The purpose of this study was to compare body composition changes of patients undergoing totally laparoscopic distal gastrectomy (TLDG) with delta-shaped anastomosis (DSA) versus conventional laparoscopic distal gastrectomy (CLDG). Data from gastric cancer patients who underwent laparoscopic distal gastrectomy for histologically proven gastric cancer in KNUMC from January 2013 to May 2014 were collected and reviewed. We examined 85 consecutive patients undergoing TLDG or CLDG: 41 patients underwent TLDG and 44 patients underwent CLDG. Body composition was assessed by segmental multifrequency bioelectrical impedance analysis. We compared the changes in nutritional parameters and body composition from preoperative status between the two groups at postoperative 6 and 12 months. All of the postoperative changes in the body composition and nutritional indices were similar between the two groups with the exception of visceral fat areas (VFAs) and albumin levels. VFAs increased at 6 months postoperatively in the TLDG group and a significant difference was shown at 12 months postoperatively between the TLDG and CLDG groups (86.7 ± 22.8 and 74.7 ± 21.9 cm(2), respectively, P body composition seemed comparable to those of CLDG. Six months postoperatively, VFAs and albumin levels were recovered in the TLDG group but not in the CLDG group. Thus, TLDG seems to be a novel surgical method.

Full Text Available Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

The purpose of this study was to compare the costs of traditional laparoscopy and robotic-assisted laparoscopy in the treatment of endometrial cancer. A total of 101 patients with endometrial cancer were randomized to the study and operated on starting from 2010 until 2013, at the Department of Obstetrics and Gynecology of Tampere University Hospital, Tampere, Finland. Costs were calculated based on internal accounting, hospital database, and purchase prices and were compared using intention-to-treat analysis. Main outcome measures were item costs and total costs related to the operation, including a 6-month postoperative follow-up. The total costs including late complications were 2160 &OV0556; higher in the robotic group (median for traditional 5823 &OV0556;, vs robot median 7983 &OV0556;, P costs for instruments and equipment as well as to more expensive operating room and postanesthesia care unit time. Traditional laparoscopy involved higher costs for operation personnel, general costs, medication used in the operation, and surgeon, although these costs were not substantial. There was no significant difference in in-patient stay, laboratory, radiology, blood products, or costs related to complications. According to this study, robotic-assisted laparoscopy is 37% more expensive than traditional laparoscopy in the treatment of endometrial cancer. The cost difference is mainly explained by amortization of the robot and its instrumentation.

The study assessed long-term shifting patterns in quality of life (QoL) after distal subtotal gastrectomy relative to an estimated healthy population QoL (HPQoL), and compared them to shifting patterns interpreted in terms of a preoperative QoL baseline. QoL data from 127 gastric cancer patients who underwent open distal subtotal gastrectomy were obtained at the preoperative period and at 6, 12, 18, 24, and 36 months after surgery. QoL data obtained from 127 age- and sex-adjusted healthy individuals were used to estimate HPQoL. The study used the European Organization for Research and Treatment of Cancer (EORTC) QoL Questionnaire Core 30 (QLQ-C30) and a gastric cancer module (QLQ-STO22) to assess QoL. Comparisons were made between preoperative-based and healthy-based interpretations of longitudinal QoL shifting patterns. Among the persistently deteriorated QoL variables indicated by the preoperative-based interpretation (physical functioning, role functioning, cognitive functioning, nausea and vomiting, dyspnea, diarrhea, dysphagia, eating restrictions, dry mouth, and body image), eating restrictions and body image concerns were the only factors indicated by a healthy-based interpretation. In this interpretation, financial difficulties were evident at the preoperative period and persisted for at least 36 months. When preoperative QoL was used as a baseline, decreased QoL due to financial difficulties was not revealed. Persistent QoL deterioration after distal subtotal gastrectomy is primarily due to financial difficulties, eating restrictions, and body image concerns. Preoperative-based interpretation of postoperative QoL may exaggerate the persistency of reduced QoL and conceal on-going QoL deterioration after surgery.

The present study was conducted to investigate the prognosis and survival of patients with locally advanced gastric cancer who underwent distal subtotal gastrectomy with modified D2 (D1+) and D2 lymphadenectomy, under 70 years of age. The five-year overall survival rates of 390 patients were compared between those receiving D1+ and D2 lymphadenectomy. Univariate and multivariate analyses were used to identify factors that correlated with prognosis and lymph node metastasis. Tumor size (P=0.039), pT stage (P=0.011), pN stage (PD2 lymphadenectomy removes sufficient lymph nodes to improve staging accuracy and survival. Therefore, D2 lymphanectomy is recommended in distal subtotal gastrectomy for locally advanced gastric cancer, especially for cancers of larger size and higher pT stage.

To identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth II reconstruction. A total of 158 patients who underwent laparoscopy-assisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University (Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y (group U) and Billroth II group (group B). Postoperative complications and relevant clinical data were compared between the two groups. According to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B (7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach pH values were lower than 7 and group B pH values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis ( P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%. Compared with Billroth II reconstruction, uncut Roux-en-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.

Conclusions: A R0 type distal subtotal gastrectomy with standard D2 lymphadenectomy for a histologically proven invasive adenocarcinoma of the distal gastric portion without distant metastasis offers acceptable postoperative morbidity and mortality, and considerably high overall cumulative 5-year survival rate. The probability of cumulative survival decreases five times when the ratio between metastatic and examined lymph nodes is > 0.25.

The aims of this study were to make serial comparisons of the quality of life (QoL) between patients who underwent total gastrectomy and those who underwent distal subtotal gastrectomy for gastric cancer and to identify the affected scales with consistency. QoL data of 275 patients who were admitted for surgery between September 2008 and June 2011 and who underwent subtotal gastrectomy or total gastrectomy were obtained preoperatively and postoperatively at 3, 6, 9, 12, 18, and 24 months. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL. QoL, as assessed by the global health status/QoL and physical functioning, revealed a brief divergence with worse QoL in the total gastrectomy group 3 months postoperatively, followed by rapid convergence. QoL related to restrictive symptoms (nausea/vomiting, dysphagia, reflux, and eating restrictions) and dry mouth was consistently worse in the total gastrectomy group during the first 2 postoperative years. The general QoL of patients after gastrectomy is highly congruent with subjective physical functioning, and the differences between patients who undergo total gastrectomy and subtotal gastrectomy are no longer valid several months after surgery. In order to further reduce the differences in QoL between patients who underwent total gastrectomy and subtotal gastrectomy, definitive preoperative informing, followed by postoperative symptomatic management, of restrictive symptoms in total gastrectomy patients is the most rational approach.

Chylous ascites is an uncommon finding which is usually associated with recent abdominal/oncologic or retroperitoneal surgery. It is not usually seen in cases of acute obstruction. A patient who had previously undergone a laparoscopy-assisted distal gastrectomy with Roux-en-Y reconstruction for early gastric cancer presented with acute abdominal pain and epigastric fullness. Computed tomography suggested small bowel obstruction due to volvulus. We were able to reduce the volvulus and close a Petersen's hernia without resecting the bowel; a large amount of chylous ascites was an incidental finding. We present a case of chylous ascites occurring in a setting of small bowel obstruction due to Petersen's hernia, 3 years after successful distal gastrectomy for early gastric cancer, with no evidence of tumor recurrence.

In totally laparoscopic distal gastrectomy, determining the resection line with safe proximal margins is often difficult, particularly for tumors located in a relatively upper area. This is because, in contrast to open surgery, identifying lesions by palpating or opening the stomach is essentially impossible. This study introduces a useful method of tumor identification that is accurate, safe, and rapid. On the operation day, after inducing general anesthesia, a mixture of sodium hyaluronate and patent blue is injected into the submucosal layer of the proximal margin. When resecting stomach, all marker spots should be on the resected side. In all cases, the proximal margin is examined histologically by using frozen sections during the operation. From October 2009 to September 2011, a prospective study that evaluated this method was performed. A total of 34 patients who underwent totally laparoscopic distal gastrectomy were enrolled in this study. Approximately 5 min was required to complete the procedure. Proximal margins were negative in all cases, and the mean ± standard deviation length of the proximal margin was 23.5 ± 12.8 mm. No side effects, such as allergy, were encountered. As a method of tumor identification for totally laparoscopic distal gastrectomy, this procedure appears accurate, safe, and rapid.

To date there have been no comprehensive, comparative assessments of the environmental impact of surgical modalities. Our study seeks to quantify and compare the total greenhouse gas emissions, or 'carbon footprint', attributable to three surgical modalities. A review of 150 staging procedures, employing laparotomy (LAP), conventional laparoscopy (LSC) or robotically-assisted laparoscopy (RA-LSC), was performed. The solid waste generated (kg) and energy consumed (kWh) during each case were quantified and converted into their equivalent mass of carbon dioxide (kg CO(2) e) release into the environment. The carbon footprint is the sum of the waste production and energy consumption during each surgery (kg CO(2) e). The total carbon footprint of a RA-LSC procedure is 40.3 kg CO(2) e/patient (p < 0.01). This represents a 38% increase over that of LSC (29.2 kg CO(2) e/patient; p < 0.01) and a 77% increase over LAP (22.7 kg CO(2) e/patient; p < 0.01). Our results provide clinicians, administrators and policy-makers with knowledge of the environmental impact of their decisions to facilitate adoption of sustainable practices.

The feasibility, safety, and improved quality of postoperative life following laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with a hand-sewn anastomosis via a mini-laparotomy for early gastric cancer (EGC) have been previously established. Here we describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy (TLPPG) using an intracorporeal delta-shaped anastomosis technique, and the short-term surgical outcomes of 60 patients with EGC in the middle stomach are reported. After lymphadenectomy and mobilization of the stomach, intraoperative gastroscopy was performed in order to verify the location of the tumor, and then the distal and proximal transecting lines were established, 5 cm from the pyloric ring and just proximal to Demel's line, respectively. Following transection of the stomach, a delta-shaped intracorporeal gastrogastrostomy was made with linear staplers. There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 259 min and 28 mL, respectively. Twelve patients (20.0%) experienced postoperative complications classified as grade II using the Clavien-Dindo classification, with the most frequent complication being gastric stasis (6 cases, 10.0 %). The incidence of severe complications classified as grade III or above was 1.7%; only one patient required reoperation and intensive care due to postoperative intraabdominal bleeding and subsequent multiple organ failure. TLPPG with an intracorporeal delta-shaped anastomosis was found to be a safe procedure, although it tended to require a longer operating time than the well-established LAPPG with a hand-sewn gastrogastrostomy.

Although recent trends in laparoscopic procedures have been toward minimizing the number of incisions, four or five ports are normally required to complete laparoscopic gastrectomy because of the complexity of this procedure. Multi-channel ports, such as the SILS port (Covidien, JAPAN), are now available and are crucial for performing single-incision laparoscopic surgery (SILS) or reduced port surgery (RPS). We carried out reduced port distal gastrectomy (RPDG) using a dual-port method with a SILS port. Ten patients who were diagnosed as early stage gastric cancer were offered the RPDG. Mean age and body mass index (BMI) were 68.1 and 21.4, respectively. No distant metastasis or regional lymph node swelling was seen in any case. A 5-mm flexible scope (Olympus, JAPAN) and SILS port were used and a nylon ligature with a straight needle, instead of a surgical instrument, was available to raise the gastric wall. The average operative time was 266.9 ± 38.3 min and blood loss was 37.8 ± 56.8 ml. Patients recovered well and experienced no complications after surgery. All patients could tolerate soft meals on the first day after surgery and the average hospital stay was 8.1 days. Past conventional LAG cases were evaluated to compare the short-term outcome and no difference was seen in the mean operative time or operative blood loss. The length of hospital stay after surgery was shorter for the RPDG group than the conventional operation group (p < 0.0001). Interestingly, the trend of serum CRP elevation after surgery was lower in the RPDG group than the conventional LAG group (p = 0.053). Although the benefits of RPS have not been established, this type of surgery may be expected to have some advantages. Cosmetic benefits and shorter hospital stays are clear advantages. Less invasiveness can be expected according to the trend of serum CRP elevation after RPDG.

Full Text Available Background. Recent studies have shown a lower risk of surgical site infections (SSI after laparoscopic distal gastrectomy compared to open surgery. This is a phase 2 study aiming to determine the incidence of SSI after laparoscopic distal gastrectomy without using antimicrobial prophylaxis (AMP. Methods. cT1N0 gastric cancers that were subject to laparoscopic distal gastrectomy were enrolled. Based on the unacceptable SSI incidence of ≥12.5% and the target SSI incidence of ≤5%, 105 patients were enrolled with an α of 0.05 and a power of 80% (ClinicalTrials.gov, NCT02200315. Results. In intention-to-treat analysis, patients did not reach the target SSI rate (12.4%, 95% confidence  interval=6.8%–19.8%. Of patients, 44 patients had a protocol violation, such as extended lymph node dissection (LND or inappropriate nonpharmacological SSI prevention measures. Per-protocol analysis excluding these patients (n=61 showed a SSI rate of 4.9%, which was within the target SSI range. Multivariate analysis revealed that extracorporeal anastomosis and extended LND were independent risk factors for SSI. Conclusions. This study failed to reach the target SSI rate without using AMP. However, per-protocol analysis suggests that no AMP might be feasible when limited LND and adequate SSI prevention measures were performed.

The safety and efficacy of radical laparoscopic distal gastrectomy (LG) with D2 lymphadenectomy for the treatment of advanced gastric cancer (AGC) remain controversial. We conducted a randomized controlled trial to compare laparoscopic and conventional open distal gastrectomy with D2 lymph node dissections for AGC. Between September 2012 and December 2014, 1,056 patients with clinical stage T2-4aN0-3M0 gastric cancer were eligible for inclusion. They were randomly assigned to either the LG with D2 lymphadenectomy group (n = 528) or the open gastrectomy (OG) with D2 lymphadenectomy group (n = 528). Fifteen experienced surgeons from 14 institutions in China participated in the study. The morbidity and mortality within 30 days after surgery between the LG (n = 519) and the OG (n = 520) groups were compared on the basis of the modified intention-to-treat principle. Postoperative complications were stratified according to the Clavien-Dindo classification. The compliance rates of D2 lymphadenectomy were similar between the LG and OG groups (99.4% v 99.6%; P = .845). The postoperative morbidity was 15.2% in the LG group and 12.9% in OG group with no significant difference (difference, 2.3%; 95% CI, -1.9 to 6.6; P = .285). The mortality rate was 0.4% for the LG group and zero for the OG group (difference, 0.4%; 95% CI, -0.4 to 1.4; P = .249). The distribution of severity was similar between the two groups (P = .314). Experienced surgeons can safely perform LG with D2 lymphadenectomy for AGC. © 2016 by American Society of Clinical Oncology.

Little information from prospective clinical trials is available on the influences of surgical approaches on postoperative body compositions and nutritional status. We designed a prospective non-randomized trial to compare postoperative chronological changes in body composition and nutritional status between laparoscopic and open distal gastrectomy for stage I gastric cancer (GC). Body compositions and nutritional indicators in blood tests were measured at the baseline and at the 1st, 3rd, 6th, and 12th postoperative months (POM). The primary end point was the decrease relative to the baseline in the body muscle mass at POM 6. Ninety-six patients for the laparoscopic group and 52 for the open group were eligible for data analysis. No significant differences were found in any baseline demographics, body compositions, and nutritional indicators between the groups. The changes of body muscle mass at POM 6 were similar in both groups. Overall, no significant differences between the groups were observed in any of the body composition and nutritional indicators during the first year after surgery. Postoperative body compositions and nutritional status were not affected by surgical approaches during the first 12 months after surgery in patients who underwent distal gastrectomy for stage I GC. © 2017 S.

Remnant gastric cancer (RGC) and gastric stump cancer after distal gastrectomy (DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer. Although eradication of Helicobacter pylori (H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis.

Robotic technology is increasingly prevalent in bariatric surgery, yet there are national deficiencies in exposure of surgical residents to robotic techniques. The purpose of this study is to accurately characterize the perioperative outcomes of a resident teaching model using the robotic-assisted sleeve gastrectomy. University Hospital. We identified 411 consecutive patients who underwent robotic sleeve gastrectomy at our institution from a prospectively maintained administrative database. Perioperative morbidity, operative time, and supply cost of the procedure were analyzed. Mean operative time was 96.4±24.9 minutes; mean robot usage time was 63.9 minutes (range 30.0-122.0 min). Ninety-day morbidities included reoperation (0.72%), major bleeding complications (0.48%), staple line leak (0.24%), stricture (0.97%), need for blood transfusion (3.86%), surgical site infection (1.69%), deep vein thrombosis (0.48%), and pulmonary embolism (0.48%). Mortality was nil. The resident cohort achieved operative time plateaus after five consecutive cases. Subset analysis for fiscal year 2014 demonstrated significantly increased supply cost for robotic sleeve gastrectomy compared with its laparoscopic equivalent. Robotic-assisted sleeve gastrectomy can be instituted as a model for resident robotic education with rates of morbidity and operative times equivalent to historical laparoscopic controls. The robot's enhanced ergonomics and its opportunity for resident education must be weighed against its increased supply cost. Copyright © 2016 American Society for Bariatric Surgery.

We present a novel minimally invasive technique, laparoscopy-assisted micropercutaneous choledocholithotripsy, for choledocholithiasis that cannot be treated with other endoscopic techniques. This technique includes standard laparoscopic exploration of the common bile duct, combined with an all-seeing needle and holmium laser lithotripsy. As is known, an all-seeing needle is used in micropercutaneous nephrolithotomy for middle-sized renal stones. In this technique, an all-seeing needle was inserted into the dilatated common bile duct under laparoscopic vision and then a lithotripsy procedure was performed with a holmium laser behind the biliary stent. A cholecystectomized female patient with a 21-mm stone in the common bile duct who previously underwent an unsuccessful endoscopic retrograde cholangiopancreatography procedure was operated on in our service with laparoscopy-assisted micropercutaneous choledocholithotomy without a T-tube. This novel procedure was completed uneventfully and the patient was discharged without any complications. In the future, this procedure will hopefully be a treatment modality in choledocholithiasis that cannot be treated by other minimally invasive techniques.

The mechanisms involved in the weight loss seen after vertical sleeve gastrectomy (VSG) are not clear. The rat stomach has two morphologically and functionally distinct proximal and distal parts. The rat model for VSG involves complete removal of the proximal part and 80% removal of the distal part along the greater curvature. The purpose of this study was to understand the potential independent contributions of removal of these distinct gastric sections to VSG outcomes. We prepared four surgical groups of male Long-Evans rats: VSG, sham surgery (control), selective proximal section removal (PR), and selective distal section removal (DR). Gastric emptying rate (GER) was highest after VSG compared with all other groups. However, PR, in turn, had significantly greater GER compared with both DR and sham groups. The surgery-induced weight loss followed the same pattern with VSG causing the greatest weight loss and PR having greater weight loss compared with DR and sham groups. The results were robust for rats fed regular chow or a high-fat diet. Body mass analysis revealed that the weight loss was due to the loss of fat mass, and there was no change in lean mass after the surgeries. In conclusion, removal of the proximal stomach contributes to most, but not all, of the physiological impact of VSG. PMID:27581811

To evaluate the long-term outcomes of pylorus-vagus-preserving partial gastrectomy for early gastric cancer in middle third of stomach. Between January 2004 and June 2009, 46 patients with early gastric cancer in middle third of stomach underwent pylorus-vagus-preserving partial gastrectomy (PPG) while another 85 patients had conventional distal gastrectomy (DG). Clinicopathologic data and follow-up results of two groups were analyzed retrospectively, including the results of subjective nutritional assessments, laboratory blood biochemical data, endoscopic findings of remnant stomach and total 5-year survival rates. Postprandial dumping syndrome occurred in 7 patients (8.2%) in DG group while no syndrome occurred in PPG group. The incidence of gallbladder stones at 18 months after operation in DG group was higher than that in PPG group. Significant difference existed between two groups (Pgastric remnant was frequently observed in PPG (31.1%) than in DG (10.8%, Pgastric cancer in middle third of stomach, pylorus-vagus-preserving partial gastrectomy is effective in maintaining postoperative function. And it has the same postoperative survival rate as conventional distal gastrectomy.

The mechanisms underlying peritoneal metastasis (PM) after curative gastrectomy for gastric cancer (GC) are not well elucidated. This study assessed whether viable cancer cells, including cancer stemlike cells (CSCs), were present in the remnant stomach immediately before gastrointestinal (GI) tract reconstruction because these could be a source of PM after gastrectomy. Saline fluid used for remnant stomach lumen irrigation before GI reconstruction was prospectively collected from 142 consecutive patients undergoing distal gastrectomy for GC and cytologically examined. Proliferative activity (Ki67 staining) and stemness (expression of the CSC surface markers CD44s or CD44v6) were evaluated in detected cancer cells. Viable cancer cells were detected in 33 (23.2 %) of the 142 remnant stomachs. These cells formed clusters and stained positively for Ki67, indicating proliferation. Cancer cells in remnant stomachs and surface cancer cells in primary GCs from 10 (30.3 %) of these 33 cases also stained positively for CD44s or CD44v6. In a multiple logistic regression analysis, advanced cancer (odds ratio [OR], 4.65; 95 % confidence interval [CI], 1.32-16.4; P = 0.017), tumor size of 40 mm or larger (OR, 3.78; 95 % CI, 1.12-12.8; P = 0.033), and histologic differentiation (OR, 3.10; 95 % CI, 1.30-7.40; P = 0.011) were associated independently with the presence of cancer cells in the remnant stomach. Viable, proliferative, and clustered cancer cells, including CSCs, were found in remnant gastric lumens immediately before GI reconstruction, indicating a possible cellular source of PM after curative gastrectomy for GC. Dissemination of gastric contents into the peritoneal cavity should be avoided during GI reconstruction.

Video-assisted laparoscopy (VALS has now replaced laparotomy as the gold standard for the diagnosis and management of endometriosis. While imaging has a role in the evaluation of some patients, histologic examination is needed for a definitive diagnosis. Laboratory evaluation currently has a minor role in the diagnosis of endometriosis, although studies are underway investigating serum markers, genetic studies, and endometrial sampling. A high index of suspicion is essential to accurately diagnose this complex condition, and a multidisciplinary approach is often indicated. The following review discusses laparoscopic diagnosis of endometriosis from the pre-operative evaluation of patients suspected of having endometriosis to surgical technique for safe and adequate laparoscopic diagnosis of the condition and postsurgical care.Keywords: endometriosis, video-assisted, laparoscopy, diagnosis

To compare the safety and efficacy of robotic-assisted distal pancreatectomy (RADP) and laparoscopic distal pancreatectomy (LDP). A literature search of PubMed, EMBASE, and the Cochrane Library database up to June 30, 2015 was performed. The following key words were used: pancreas, distal pancreatectomy, pancreatic, laparoscopic, laparoscopy, robotic, and robotic-assisted. Fixed and random effects models were applied. Study quality was assessed using the Newcastle-Ottawa Scale. Seven non-randomized controlled trials involving 568 patients met the inclusion criteria. Compared with LDP, RADP was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, R0 resection rate, lymph nodes harvested, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups. RADP is a safe and feasible alternative to LDP with regard to short-term outcomes. Further studies on the long-term outcomes of these surgical techniques are required. To date, there is no consensus on whether laparoscopic or robotic-assisted distal pancreatectomy is more beneficial to the patient. This is the first meta-analysis to compare laparoscopic and robotic-assisted distal pancreatectomy. We found that robotic-assisted distal pancreatectomy was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups.

Full Text Available Background. Some meta-analyses of case-controlled studies (CCSs have shown that laparoscopic or laparoscopy-assisted total gastrectomy (LTG had some short-term advantages over open total gastrectomy (OTG. However, postoperative complications differed somewhat among the meta-analyses, and some CCSs included in the meta-analyses had mismatched factors between LTG and OTG. Methods. CCSs comparing postoperative complications between LTG and OTG were identified in PubMed and Embase. Studies matched for patients’ status, tumor stage, and the extents of lymph-node dissection were included. Outcomes of interest, such as anastomotic, other intra-abdominal, wound, and pulmonary complications, were evaluated in a meta-analysis performed using Review Manager version 5.3 software. Result. This meta-analysis included a total of 2,560 patients (LTG, 1,073 patients; OTG, 1,487 patients from 15 CCSs. Wound complications were significantly less frequent in LTG than in OTG (n = 2,430; odds ratio [OR] 0.30, 95% confidence interval [CI] 0.29–0.85, P=0.01, I2 = 0%, and OR 0.46, 95% CI 0.17–0.52, P<0.0001, I2 = 0%. However, the incidence of anastomotic complications was slightly but not significantly higher in LTG than in OTG (n = 2,560; OR 1.44, 95% CI 0.96–2.16, P=0.08, I2 = 0%. Conclusion. LTG was associated with a lower incidence of wound-related postoperative complications than was OTG in this meta-analysis of CCSs; however, some concern remains about anastomotic problems associated with LTG.

Full Text Available Abstract Background Laparoscopic gastrectomy is a new and technically challenging surgical procedure with potential benefit. The objective of this study was to investigate clinical and para-clinical consequences following Roux-en-Y and Jejunal Loop interposition reconstructive techniques for subtotal gastrectomy using laparoscopic assisted surgery. Results Following resection of the stomach attachments through a laparoscopic approach, stomach was removed and reconstruction was performed with either standard Roux-en-Y (n = 5 or Jejunal Loop interposition (n = 5 methods. Weight changes were monitored on a daily basis and blood samples were collected on Days 0, 7 and 21 post surgery. A fecal sample was collected on Day 28 after surgery to evaluate fat content. One month post surgery, positive contrast radiography was conducted at 5, 10, 20, 40, 60 and 90 minutes after oral administration of barium sulfate, to evaluate the postoperative complications. There was a gradual decline in body weight in both experimental groups after surgery (P  0.05. Fecal fat content increased in the Roux-en-Y compared to the Jejunal loop interposition technique (P  0.05. Conclusion Roux-en-Y and Jejunal loop interposition techniques might be considered as suitable approaches for reconstructing gastro-intestinal tract following gastrectomy in dogs. The results of this study warrant further investigation with a larger number of animals.

It is well known that gastrectomy with curative intent is the best way to improve outcomes of patients with remnant gastric cancer. Recently,several investigators reported their experiences with laparoscopic gastrectomy of remnant gastric cancer. We report the case of an 83-year-old female patient who was diagnosed with remnant gastric cancer with obstruction. She underwent an entirely laparoscopic distal gastrectomy with colectomy because of direct invasion of the transverse colon. The opera...

The aim of the study was to compare the clinical symptoms between Billroth II (B-II) and Roux-en-Y (R-Y) reconstruction after distal subtotal gastrectomy (DG) for gastric cancer. Surgery is the mainstay of curative treatment for gastric cancer. The technique for reconstruction after DG remains controversial. Both B-II and R-Y are popular methods. This is a prospective multicenter randomized controlled trial. From October 2008 to October 2014, 162 patients who underwent DG were randomly allocated to B-II (n = 81) and R-Y (n = 81) groups. The primary endpoint is Gastrointestinal (GI) Symptoms Score 1 year after surgery. We also compared the nutritional status, extent of gastritis on endoscopy, and quality of life after surgery between the 2 procedures at 1 year. Operative time was significantly shorter for B-II than for R-Y [mean difference 21.5 minutes, 95% confidence interval (95% CI) 3.8-39.3, P = 0.019]. The B-II and R-Y groups had a peri-operative morbidity of 28.4% and 33.8%, respectively (P = 0.500) and a 30-day mortality of 2.5% and 1.2%, respectively (P = 0.500). GI symptoms score did not differ between R-Y versus B-II reconstruction (mean difference -0.45, 95% CI -1.21 to 0.31, P = 0.232). R-Y resulted in a lower median endoscopic grade for gastritis versus B-II (mean difference -1.32, 95% CI -1.67 to -0.98, P Y versus B-II mean difference -0.31, 95% CI -3.27 to 2.65, P = 0.837) and quality of life at 1 year between the 2 groups too. Although BII is associated with a higher incidence of heartburn symptom and higher median endoscopic grade for gastritis, BII and RY are similar in terms of overall GI symptom score and nutritional status at 1 year after distal gastrectomy.

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic gastrectomy, however, is adopted in only a few selected centers. The goals of this study were to examine the adoption of robotic gastrectomy and to compare outcomes between open and robotic gastric resections. This is a case-matched analysis of patients who underwent robotic and open gastric resection performed at Sanchinarro University Hospital, Madrid from November 2011 to February 2017. Patient data were obtained retrospectively. Clinicopathologic characteristics and perioperative and postoperative outcomes were recorded and analyzed. Two groups of demographically similar patients were analyzed: the robotic group (n = 20) and the open surgery group (n = 19). The patient characteristics of the two groups have been compared. Robotic resection resulted in less blood loss, shorter postoperative hospital stay, and a longer operating time. The two groups had similar complication rates. Pathological data were similar for both procedures. Robotic gastrectomy for locally advanced gastric carcinoma is safe, and long-term outcomes are comparable to those patients who underwent open resection. Robotic gastrectomy resulted in a shorter hospital stay, less blood loss and morbidity comparable with the outcomes of open gastrectomy.

Full Text Available Laparoscopic treatment strategies for synchronous intra-abdominal malignancies have not yet been standardized. We report a successful case of two-step laparoscopic surgery for synchronous double cancer of the colon and stomach accompanied by severe chronic obstructive pulmonary disease (COPD. A 66-year-old man with COPD was diagnosed as having advanced colon cancer and early gastric cancer. On admission, he could not go upstairs (Grade III according to the Hugh-Jones classification and his forced expiratory volume in 1 second was 600 mL (35.9%. The patient initially underwent laparoscopy-assisted sigmoidectomy with D3 lymphadenectomy, followed by laparoscopy-assisted distal gastrectomy with D1 lymphadenectomy 68 days later. The patient's each postoperative course was uneventful with no pulmonary complications, and the patient was discharged 9 and 11 days after the first and second operations, respectively. The present case demonstrates that two-step laparoscopic surgery may be a safe and feasible surgical procedure for high-risk patients with synchronous intra-abdominal malignancies.

Full Text Available Objective: To evaluate the safety and efficacy of early rehabilitation after surgery program (ERAS in patients undergoing laparoscopic assisted total gastrectomy. Materials And Methods: This is a study where 47 patients who are undergoing lap assisted total gastrectomy are selected. Twenty-two (n = 22 patients received enhanced recovery programme (ERAS management and rest twenty-five (n = 25 conventional management during the perioperative period. The length of postoperative hospital stay, time to passage of first flatus, intraoperative and postoperative complications, readmission rate and 30 day mortality is compared. Serum levels of C-reactive protein pre-operatively and also on post-op day 1 and 3 are compared. Results: Postoperative hospital stay is shorter in ERAS group (78 ± 26 h when compared to conventional group (140 ± 28 h. ERAS group passed flatus earlier than conventional group (37 ± 9 h vs. 74 ± 16 h. There is no significant difference in complications between the two groups. Serum levels of CRP are significantly low in ERAS group in comparison to conventional group. [d1 (52.40 ± 10.43 g/L vs. (73.07 ± 19.32 g/L, d3 (126.10 ± 18.62 g/L vs. (160.72 ± 26.18 g/L]. Conclusion: ERAS in lap-assisted total gastrectomy is safe, feasible and efficient and it can ameliorate post-operative stress and accelerate postoperative rehabilitation in patients with gastric cancer. Short term follow up results are encouraging but we need long term studies to know its long term benefits.

Although some studies have reported the safety of early oral intake after gastrectomy, it still remains controversial. This study focused on the feasibility of a clinical pathway with early oral intake and discharge setting for exclusively laparoscopic distal gastrectomy. A clinical pathway was applied to 403 patients until December 2014. In the protocol, patients are allowed to take a sip of water and a soft diet on the first and second days after the operation, respectively, and the discharge day is set as the fifth to seventh day after the operation. Clinicopathological variables were prospectively collected, and risk factors for discharge variances were analyzed. The completion rate of the clinical pathway was 76.9%. There were five re-admissions (1.2%). The overall morbidity rate was 18% ( n = 72), and major complications (Clavien-Dindo IIIa or greater) occurred in 13 patients (3%). Complications were the causes for discharge variances in 68 cases (73%), while the attending surgeons' judgment was the cause in 25 cases (27%). On multivariate analysis, age (odds ratio = 2.23, 95% confidence interval = 1.38-3.60, p = 0.001) and operative time (odds ratio = 2.38, 95% confidence interval = 1.45-3.98, p = 0.001) were independent risk factors for discharge variances. A high completion rate of a clinical pathway with early oral intake and discharge setting for laparoscopic distal gastrectomy was achievable with an acceptably low re-admission rate. Laparoscopic distal gastrectomy is recommended as a first step for a clinical pathway with an early oral intake and discharge protocol.

To evaluate single-port assisted extracorporeal cystectomy for treatment of large ovarian cysts and to compare its surgical outcomes, complications, and cystic content spillage rates with those of conventional laparoscopy and laparotomy. Retrospective study (Canadian Task Force classification II-2). University teaching hospital. Twenty-five patients who underwent single-port assisted extracorporeal cystectomy (group 1), 33 patients who underwent conventional laparoscopy (group 2), and 25 patients who underwent laparotomy (group 3). Surgical outcomes, complications, and spillage rates in group 1 were compared with those in groups 2 and 3. Patients characteristics and tumor histologic findings were similar in the 3 groups. The mean (SD) largest diameter of ovarian cysts was 11.4 (4.2) cm in group 1, 9.7 (2.3) cm in group 2, and 12.0 (3.4) cm in group 3. Operative time in groups 1 and 2 was similar at 69.3 (26.3) minutes vs 73.1 (36.3) minutes (p = .66); however, operative time in group 1 was shorter than in group 3, at 69.3 (26.3) minutes vs 87.5 (26.6) minutes (p =.02). Blood loss in group 1 was significantly lower than in groups 2 and 3, at 16.0 (19.4) mL vs 36.1 (20.7) mL (p < .001) and 16.0 (19.4) mL vs 42.2 (39.7) mL (p = .005). The spillage rate in group 1 was profoundly lower than in group 2, at 8.0% vs 69.7% (p < .001). Single-port assisted extracorporeal cystectomy offers an alternative to conventional laparoscopy and laparotomy for management of large ovarian cysts, with comparable surgical outcomes. Furthermore, cyst content spillage rate in single-port assisted extracorporeal cystectomy was remarkably lower than that in conventional laparoscopy. Copyright © 2015. Published by Elsevier Inc.

Gastric carcinomas are common malignancies in southern India and distal stomach remains the commonest site in low socio economic groups. Surgery still remains an important modality of treatment to achieve local control and also relieve obstructive symptoms. In this study we investigated the feasibility of performing a gastrectomy and billroth-1 type of anastomosis in a rural cancer center setting, with parameters like adequacy of margins, ease of anastomosis and its functional results were analysed. Eight patients presenting to a rurally based cancer center underwent a distal gastrectomy and billroth-1 type of anastomosis for continuity restoration. All the patients had adequate proximal and distal marg. The surgical time varied between-hrs. The anastomosis was constructed without any tension on bowel ends in all patients. The average time to start oral feeds varied between- None of the patients showed symptoms of bile reflux nor dumping. The average hospital stay varied between. Billroth-1 anastomosis is a physiologically more natural way of restoring continuity following a gastrectomy and it is a procedure which would be technically more simpler and decrease per and post operative complications and allow speedier post operative recovery following surgery on distal gastric cancers.

To evaluate the importance of salpingoscopy together with laparoscopy in the diagnosis of tubal pathology. Salpingoscopy was performed as a complementary method in patients who were subjected to diagnostic laparoscopy. The relationship between the salpingoscopy and (1) the patient's previous history of tubal disease and (2) laparoscopic diagnoses was evaluated. Private patients referred to the Instituto de Fertilidad, Buenos Aires. Forty-two patients undergoing a diagnostic laparoscopy during the evaluation of their fertility or as a follow-up of previous therapy. Salpingoscopy was performed, using a colpomicrohysteroscope. We evaluated alterations in major and minor folds and their vascularization, the presence of microadhesions, and cellular nuclei dyed with methylene blue in the tubal lumen. Fifty percent of the patients who had no previous history of tubal disease presented with endosalpingeal alterations, and in 37% of the normal laparoscopies the salpinx had unilateral or bilateral salpingoscopic abnormalities. Salpingoscopy is a useful method to evaluate oviducts, before assuming their normality, and consideration of these women for assisted reproductive technology.

Most risk adjustment approaches adjust for patient comorbidities and the primary procedure. However, procedures done at the same time as the index case may increase operative risk and merit inclusion in adjustment models for fair hospital comparisons. Our objectives were to evaluate the impact of surgical complexity on postoperative outcomes and hospital comparisons in gastric cancer surgery. Patients who underwent gastric resection for cancer were identified from a large clinical dataset. Procedure complexity was characterized using secondary procedure CPT codes and work relative value units (RVUs). Regression models were developed to evaluate the association between complexity variables and outcomes. The impact of complexity adjustment on model performance and hospital comparisons was examined. Among 3,467 patients who underwent gastrectomy for adenocarcinoma, 2,171 operations were distal and 1,296 total. A secondary procedure was reported for 33% of distal gastrectomies and 59% of total gastrectomies. Six of 10 secondary procedures were associated with adverse outcomes. For example, patients who underwent a synchronous bowel resection had a higher risk of mortality (odds ratio [OR], 2.14; 95% CI, 1.07-4.29) and reoperation (OR, 2.09; 95% CI, 1.26-3.47). Model performance was slightly better for nearly all outcomes with complexity adjustment (mortality c-statistics: standard model, 0.853; secondary procedure model, 0.858; RVU model, 0.855). Hospital ranking did not change substantially after complexity adjustment. Surgical complexity variables are associated with adverse outcomes in gastrectomy, but complexity adjustment does not affect hospital rankings appreciably. Copyright © 2015 Elsevier Inc.

During the period from 1968--1977 2400 laparoscopies were performed. Of these 10.7% were for diagnostic purposes only, in 3.6% of the cases laparoscopy was combined with biopsie and in 85.7% with tubal sterilization. Deaths or serious bleedings did not occur, laparotomies were not necessary. Total insignificant complications amounted to 1.6% (1.3% small bleedings which did not necessitate an operation and in 0.3% clinical signs of peritonitis, these disappeared after 3 to 15 days). In 0.7% laparoscopy was interrupted because of poor vision. Nine of 2055 women became pregnant after sterilization (4.5 pregnancies/1000 sterilizations). In 2 cases the ligamentum rotundum was coagulated, in 7 cases recanalization was histologically confirmed. Until Oct. 1975 coagulation was unipolar, afterwords bipolar. In 45.3% the patients had undergone an operation before, like Ceasarian section, gallbladder operation, appendectomy or umbilical hernia operation. Patients with longitudinal incision, with preceding peritonitis or ileus were excluded from laparoscopy. Laparoscopy was performed by all assistents during their last year of clinical instruction. Their first 30 laparoscopies were done under control, every assistent performed about 100 laparoscopies.

The clinicopathologic features of 45 consecutive patients who underwent minimally-invasive distal pancreatectomy from 2006 to 2015 were retrospectively reviewed. Thirty-nine patients who met our study criteria were included. Eight patients underwent RDP and 31 had LDP. There were 10 (25.6%) open conversions. Six (15.4%) patients had major (> grade 2) morbidities and there was no in-hospital mortality. There were 14 (35.9%) grade A and 9 (23.1%) grade B pancreatic fistulas. Comparison between RDP and LDP demonstrated no significant difference between the patients' baseline characteristics except there was increased frequency of spleen-preserving pancreatectomies (3 (37.5%) vs 25 (80.6%), P=0.016) and splenic-vessel preservation (5 (62.5%) vs 4 (12.9%), P=0.003) in RDP. Comparison between outcomes demonstrated that RDP was associated with a longer median operation time (452.5 (range, 300-685) vs 245 min (range, 85-430), P=0.001) and increased frequency of the procedure completed purely laparoscopically (8 (100%) vs 18 (58.1%), P=0.025). RDP can be safely adopted and is equivalent to LDP in most perioperative outcomes. It is also associated with a decreased frequency of the need for hand-assistance laparoscopic surgery or open conversion but needed a longer operation time. Copyright © 2016 John Wiley & Sons, Ltd.

Higher morbidity in total gastrectomy than in distal gastrectomy has been reported, but laparoscopic subtotal gastrectomy (LsTG) has been reported to be safe and feasible in early gastric cancer (GC). We determined the surgical, nutritional and oncological outcomes of LsTG for advanced gastric cancer (AGC). Of the 816 consecutive patients with GC who underwent radical gastrectomy at our institution between 2008 and 2012, 253 who underwent curative laparoscopic gastrectomy (LG) for AGC were enrolled. LsTG was indicated for patients with upper stomach third tumors, who hoped to avoid total gastrectomy, nutritional status were primarily assessed. Of 253 patients, the morbidity (Clavien-Dindo classification grade ≥ III) was 17.0% (43 patients). The 3-year overall survival and 3-year recurrence-free survival rates were 80.2 and 73.5%, respectively. LcDG, LsTG and LTG were performed in 121, 27 and 105 patients, individually. Morbidity was strongly associated with LTG (P = 0.001). Postoperative loss of body weight was significantly greater after LTG in comparison with LcDG or LsTG (P nutritional point of view.

After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5 th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.

Ventriculoperitoneal shunts (VPS) are the primary treatment for hydrocephalus and are associated with a high risk of complications, specifically in patients who are obese or have abdominal adhesions or shunt revisions. The present study describes the use of a novel type of peritoneal catheter peritoneocentesis trocar insertion with the assistance of a one-port laparoscope. A total of 36 patients with hydrocephalus underwent this novel type of peritoneocentesis trocar-assisted VPS. The distal shunt catheter was placed into the right subdiaphragmatic space and the catheter was traversed through a single hole drilled through the liver falciform ligament. The duration of the laparoscopic surgery ranged from 6-18 min (mean 10.4±1.6 min). No shunt-related infections or catheter malfunctions or injuries to the intra-abdominal organs occurred. The total abdominal incision length was 1.0 cm (0.5+0.5 cm). No laparoscopy-related complications were observed during follow-up assessments. The novel approach used in the current study is very easy to perform, and this method may significantly reduce the risk of malfunction complications. The presented method also has the advantages of reduced trauma and a simpler surgery. The current study indicated that this simple, minimally invasive procedure was beneficial for patients with hydrocephalus, specifically in cases of patients with obesity, peritoneal adhesions or shunt revisions.

We aimed at assessing the effect of using a "Funada-kit II" device during laparoscopy-assisted percutaneous endoscopic gastrostomy (Lap-PEG), by reviewing 29 cases of Lap-PEG we performed from 2001 to 2011. We started using the "Funada-kit II" (CREATE MEDIC CO., Kanagawa, Japan) device with two parallel needles to puncture the stomach and assist suturing the anterior gastric wall to the anterior abdominal wall during Lap-PEG in 2011 (F-PEG). By introducing a loop through the lumen of one needle which allows placement of a suture introduced through the lumen of the other needle. Once repeated, the stomach can be pexied at two points, approximately 2 cm apart. We compared Lap-PEG (n = 23) with F-PEG (n = 6) where the mean ages and weights at surgery and sex ratios were similar. All cases were uneventful without intraoperative complications, although one postoperative wound infection occurred in a Lap-PEG case. There were no differences in the duration of analgesia, time taken to commence tube feeding, and return to full feeding. However, mean operating time was significantly shorter in F-PEG (28.1 min) versus Lap-PEG (46.1 min) p < 0.05. As per results F-PEG would appear to be as safe as Lap-PEG, but much quicker.

The patient was a 65-year-old woman. She was diagnosed with advanced gastric cancer with liver invasion. After receiving systemic chemotherapy (S-1 plus PTX) for 3 months, she underwent total gastrectomy and partial hepatectomy in May 2008. Because she developed celiac artery circumference lymph node recurrence in November 2010 during postoperative adjuvant chemotherapy consisting of S-1 plus PTX, we changed her chemotherapy regimen to CPT-11 plus CDDP. We observed an increase in the size of the lymph nodes in August 2013 and the response was poor even after switching to DOC. However, the lymph nodes continued to increase in size and we administered radiotherapy of 60.4 Gy/33 Fr that resulted in shrinkage of the nodes. We observed an increase in lymph node size and pancreas invasion in September 2015, including an expansion of the mid pancreatic duct. We performed distal pancreatectomy without identifying the recurrence observed in November 2015 assuming it was an exacerbation. Six months after the surgery, the recurrence was not apparent. We report an example of long-term survival that was achieved for Stage 4 gastric cancer. The patient underwent combined modality therapy for 8 years, and local recurrence was controlled via a primary operation. (author)

The European Organization for Research and Treatment of Cancer quality-of-life questionnaire-OG25 was developed to evaluate the quality of life in patients with stomach and esophageal cancer. The following are included in the OG25 but not in the STO22: odynophagia, choked when swallowing, weight loss, trouble eating with others, trouble swallowing saliva, trouble talking, and trouble with coughing. In this study, we evaluated the quality of life of gastrectomized patients using both, the OG25 and the STO22. A total of 138 patients with partial gastrectomy (PG) (distal gastrectomy=91; pylorus-preserving gastrectomy= 47) and 44 patients with total gastrectomy (TG) were prospectively evaluated. Body weight and scores from the OG25 and STO22 were evaluated preoperatively and at 3 weeks, 3 months, and 6 months after surgery. Patients with TG had significant weight loss compared to patients with PG. At 3 months, TG was associated with worse scores for dysphagia, eating, odynophagia, trouble eating with others, trouble with taste, and weight loss on the OG25. TG was also associated with dysphagia, eating restrictions, and anxiety on the STO22. The OG25 helped differentiate between the groups with respect to weight loss, odynophagia, choked when swallowing, and trouble eating with others. The OG25 scores changed over time and were significantly different. The OG25 is a more sensitive and useful scale than the STO22 for evaluating the quality of life of gastrectomized patients, especially those with total gastrectomy.

Computer-assisted versus non-computer-assisted preoperative planning of corrective osteotomy for extra-articular distal radius malunions: a randomized controlled trial

Directory of Open Access Journals (Sweden)

Stockmans Filip

2010-12-01

Full Text Available Abstract Background Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical planning, combined with patient-specific surgical guides, has the potential to improve pre-operative understanding of patient anatomy as well as intra-operative accuracy. For patients with malunion of the distal radius fracture, this technology could significantly improve clinical outcomes that largely depend on the quality of restoration of normal anatomy. Therefore, the objective of this study is to compare patient outcomes after corrective osteotomy for distal radius malunion with and without preoperative computer-assisted planning and peri-operative patient-specific surgical guides. Methods/Design This study is a multi-center randomized controlled trial of conventional planning versus computer-assisted planning for surgical correction of distal radius malunion. Adult patients with extra-articular malunion of the distal radius will be invited to enroll in our study. After providing informed consent, subjects will be randomized to two groups: one group will receive corrective surgery with conventional preoperative planning, while the other will receive corrective surgery with computer-assisted pre-operative planning and peri-operative patient specific surgical guides. In the computer-assisted planning group, a CT scan of the affected forearm as well as the normal, contralateral forearm will be obtained. The images will be used to construct a 3D anatomical model of the defect and patient-specific surgical guides will be manufactured. Outcome will be measured by DASH and PRWE scores, grip strength, radiographic measurements, and patient satisfaction at 3, 6, and 12 months

The volume-outcome relationship in laparoscopic surgery is controversial. This study was designed to identify differences in laparoscopic gastrectomy outcomes between a low-volume hospital and a high-volume center and to provide guidelines for overcoming the problems associated with a low-volume hospital. From April 2009 to November 2012, one surgeon performed 134 totally laparoscopic distal gastrectomies (TLDGs) at a high-volume center (HVC; ASAN Medical Center) and at a low-volume hospital (LVH; Hanyang University Guri Hospital). All laparoscopically assisted gastrectomies were excluded from this study. During the early period of laparoscopic gastrectomy at the low-volume hospital, TLDG with Roux-en-Y gastrojejunostomy (RYGJ) was performed according to the surgeon's choice. The reconstruction method was classified as gastroduodenostomy (GD) or RYGJ. Early surgical outcomes achieved at the LVH were investigated and compared with those obtained at the HVC. The early surgical outcomes differed significantly between the two hospitals. In particular, the postoperative complication rate for the patients who underwent TLDG RYGJ at the LVH was higher than at the HVC (LVH 15.4 % vs. HVC 0 %; p = 0.037). Furthermore, significant differences were observed in the mean operation time (TLDG GD: LVH 141.0 min vs. HVC 117.4 min, p = 0.001; TLDG RYGJ: LVH 186.3 min vs. HVC 134.6 min, p = 0.009) and length of hospital stay (TLDG GD: LVH 8.1 days vs. HVC 7.2 days, p = 0.044; TLDG RYGJ: LVH 11.5 day vs. HVC 6.8 day, p = 0.009). Although all the operations were performed by one experienced surgeon, the early surgical outcomes differed significantly between the low- and high-volume hospitals. Low-volume hospitals often lack well-trained surgical professionals such as first assistants and scrub nurses. Therefore, the authors recommend that a surgeon who works at an LVH should assess potential personnel shortages and find a solution before operating.

Small bowel injuries after blunt abdominal trauma represent both a diagnostic and a therapeutic challenge. Early diagnosis and prompt treatment are necessary in order to avoid a dangerous diagnostic delay. Laparoscopy can represent a diagnostic and therapeutic tool in patients with uncertain clinical symptoms. We report the case of a 25-year-old man, haemodynamically stable, admitted for acute abdominal pain a few hours after a physical assault. Giving the persistence of the abdominal pain and the presence of free fluids at the computed tomography examination, an exploratory laparoscopy was performed. At the laparoscopic exploration, an isolated small bowel perforation was found, 60 cm distal from the ligament of Treitz. The injury was repaired by laparoscopic suturing and the patient was discharged home at postoperative day 3 after an uneventful postoperative course. Laparoscopy represents a valuable tool for patients with small bowel blunt injuries allowing a timely diagnosis and a prompt treatment.

Full Text Available BACKGROUND: To evaluate the prevalence of the accessory left hepatic artery (ALHA; defined as a vessel arising from the left gastric artery, which, together with a typical left hepatic artery, supplies blood to the left lobe of the liver and its short-term clinical implications in patients undergoing radical gastrectomy for gastric cancer. METHODS: Clinical data of 1173 patients with gastric cancer who underwent laparoscopy-assisted radical gastrectomy were retrospectively analyzed. Groups of patients with and without ALHA were compared to identify differences in intraoperative and postoperative variables and changes in liver function. RESULTS: Of the 1173 patients, 135 (11.5% had an ALHA and 1038 (88.5% did not. There were no significant between-group differences in clinicopathological and intraoperative characteristics, postoperative recovery, and morbidity and mortality rates (P>0.05 each. None of the patients had postoperative symptoms associated with impaired liver function. Glutamic oxaloacetic transaminase (GOT, glutamic pyruvic transaminase (GPT and total bilirubin (TBIL concentrations were similar preoperatively. TBIL concentrations on postoperative days 1, 3, and 7 were similar (P>0.05, while GOT and GPT activities were higher in the ALHA than in the non-ALHA group on days 1 and 7 (P<0.05, with all three markers similar in the two groups on day 14. In patients without chronic liver disease (CLD, GOT, GPT and TBIL concentrations were similar in patients with and without ALHA; whereas, in patients with CLD, GOT and GPT concentrations on days 1 and 3 and GOT on day 7 were higher in patients with than without ALHA. CONCLUSION: ALHA is a common anomaly that was found in 11.5% of patients. It can be safely severed during radical gastrectomy in patients without CLD, but should be left intact in patients with CLD to prevent liver dysfunction. If severed in the latter, the patient should be monitored and liver-protecting therapy may be

To compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer. Unicentric retrospective study (Canadian Task Force classification II-2). Tertiary teaching hospital. The study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups. The study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events. Robotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.

3D laparoscopy allows the surgeon to regain the sense of depth and improve accuracy. The aim of the study was to assess the impact of 3D in bariatric surgery. A retrospective cohort study was conducted. All our patients who underwent bariatric surgery (sleeve gastrectomy (SG) or gastric bypass (GB)) between 2013 and 2016 were included. We compared 3D laparoscopy cohort and 2D laparoscopy cohort. Variables are as follows: age, sex, DM, hypertension, surgeon experience, and type of intervention. Comparisons of operative time, hospital stay, conversion, complications, reoperation, and exitus are completed. Three hundred twelve consecutive patients were included. 56.9% of patients underwent GB and 43.1% SG. Global complications were 3.2% (fistula 2.5%, hemoperitoneum 0.3%, others 0.4%). One hundred four procedures were performed in the 3D cohort and 208 in the 2D cohort. The 2D cohort and 3D cohort were similar regarding the following: percentage of GB vs SG, age, gender, learning curve, diabetes mellitus 2, hypertension, and sleep apnea. The operating time and hospital stay were significantly reduced in the 3D cohort (144.07 ± 58.07 vs 172.11 ± 76.11 min and 5.12 ± 9.6 vs 7.7 ± 13.2 days. It was the same when we stratified the sample by type of surgery or experience of the surgeon. Complications were reduced in the 3D cohort in the surgeries performed by novice surgeons (10.2 vs 1.8%, p = 0.034). The use of 3D laparoscopy in bariatric surgery in our center has helped reducing the operating time and hospital stay, and improving the safety of the surgery, either in GB or SG, being equally favorable in novice or more experienced surgeons.

To compare the precision of computer-assisted surgery with a conventional technique (CV) using a special guiding device for screw insertion into the distal sesamoid bone in horses. In vitro experimental study. Cadaveric forelimb specimens. Insertion of a 3.5 mm cortex screw in lag fashion along the longitudinal axis of intact (non-fractured) distal sesamoid bones was evaluated in 2 groups (8 limbs each): CV and computer-assisted surgery (CAS). For CV, the screw was inserted using a special guiding device and fluoroscopy, whereas for CAS, the screw was inserted using computer-assisted navigation. The accuracy of screw placement was verified by radiography, computed tomography, and specimen dissection. Surgical precision was better in CAS compared with CV. CAS improves the accuracy of lateromedial screw insertion, in lag fashion, into the distal sesamoid bone. The CAS technique should be considered for improved accuracy of screw insertion in fractures of the distal sesamoid bone.

Full Text Available Background: More than 3 decades after the introduction of in vitro fertilization (IVF and despite the improved success rates of assisted reproductive technologies, the argument for performing laparoscopy as a part of the infertility workup still stands. Objective: To evaluate the role of laparoscopy±hysteroscopy in diagnosis and management of infertility in our setting in view of modern fertility practice. Materials and Methods: This case control study was carried out on 600 infertile women subjected to laparoscopy or combined laparoscopy and hysteroscopy at endoscopy unit in Minia University Hospital, Egypt during the period from January 2012 to December 2014. Results: The causes of infertility as identified by laparoscopy±hysteroscopy were polycystic ovary syndrome (25.1%, tubal factor (30%, uterine cause (4%, and endometriosis (2.7%. No cause was identified in 38.2% of cases. Based on operative findings, women were treated with different options. Expectant management was used in 92 cases (15.3%. Ovulation induction with anti-estrogens or gonadotropins was used in 372 cases (62%. Sixty cases (10% had intrauterine insemination and sixty four cases (10.7% underwent in vitro fertilization (IVF / intracytoplasmic sperm injection (ICSI treatment. Within 1 yr after laparoscopy, 180 cases achieved pregnancy (30%. The most favorable outcome was recorded in women with unexplained infertility (36.7% of cases got pregnant followed by women with polycystic ovary syndrome (27.8%. Participants with uterine and tubal infertility factor achieved pregnancy in 25% and 22.8% of cases, respectively. The worst outcome was recorded in women with endometriosis. Conclusion: Laparoscopy still has an important role in the diagnosis and treatment of infertility.

The aim of this study was to analyze the oncological aspects of gastric cancer following laparoscopic gastrectomy with D2 lymphadenectomy (LG-D2). We retrospectively evaluated the long-term outcomes of 354 patients who underwent LG-D2 for primary gastric cancer. Recurrence patterns and predictors of peritoneal metastasis were analyzed. Median follow-up time was 43.8 months. Five-year overall survival rates for yp/pStages I, II, and III gastric cancer were 93.7, 78.5, and 42.2 %, respectively. Recurrence was observed in 86 patients. Peritoneal metastasis was the most frequent recurrence pattern (n = 51), followed by hepatic metastasis (n = 17). Lymphatic recurrence at distant sites was observed in 10 patients. No locoregional lymph node metastasis or local recurrence was seen. Nine of 51 cases of peritoneal recurrence were detected by probe laparoscopy. Peritoneal recurrence rates were significantly higher in yp/pT4 and yp/pN3 diseases compared with yp/pT ≤ 3 and yp/pN ≤ 2 diseases. Multivariate analyses demonstrated that yp/pT4, yp/pN3, tumor size ≥70 mm, vascular invasion, and undifferentiated tumors were predictors of peritoneal recurrence following LG-D2. Long-term outcomes of gastric cancer following LG-D2, including recurrence patterns and predictors of peritoneal metastasis, were comparable to those following open D2 gastrectomy. LG-D2 showed good local control. Probe laparoscopy after LG may be effective in detecting peritoneal recurrence, which is not determined with less invasive examinations, including a CT scan. Future large-scale prospective studies are desirable to evaluate not only surgical but also oncological benefits and safety of LG-D2 for advanced gastric cancer.

Full Text Available Multiple shunt failure is a challenge in pediatric neurosurgery practice and one of the most feared complications of hydrocephalus. Objective: To demonstrate that laparoscopic procedures for distal ventriculoperitoneal shunt failure may be an effective option for patients who underwent multiple revisions due to repetitive manipulation of the peritoneal cavity, abdominal pseudocyst, peritonitis or other situations leading to a “non reliable” peritoneum. Method: From March 2012 to February 2013, the authors reviewed retrospectively the charts of six patients born and followed up at our institution, which presented with previous intra-peritoneal complications and underwent ventriculoperitoneal shunt revision assisted by video laparoscopy. Results: After a mean follow-up period of nine months, all patients are well and no further shunt failure was identified so far. Conclusion: Laparoscopy assisted shunt revision in children may be, in selected cases, an effective option for patients with multiple peritoneal complications due to ventriculo-peritoneal shunting.

Full Text Available Aim: To evaluate an alternative way of reducing intussusceptions under laparoscopic guidance. Materials and Methods: This is a retrospective observational study of children who underwent laparoscopy-assisted hydrostatic in situ reduction of intussusceptions (LAHIRI. Under general anesthesia with laparoscopic vision, warm saline was infused into the rectum with a 16-18 F Foley catheter and a drip set till the intussusception was reduced. Results: Eleven patients [age 7.8 (±2.8 months] were operated over a period of 1 year. Ten (90.9% patients had ileocolic intussusception, which got completely reduced, but one (9% had ileo-ileocolic intusussception, in whom manual reduction by extending the subumbilical incision was required to reduce the ileoileal part. The mean duration of surgery was 38.5 (±6.6 min. No patient had bowel ischemia and there were no intra- or postoperative complications. Conclusions: LAHIRI appears to be an effective and safe technique in children. Specific advantages are that it is performed in a controlled environment in the operating room, avoids patient apprehension and discomfort, avoids bowel handling, provides a safe opportunity to create higher intraluminal pressure, ensures visual assessment of bowel vascularity and completeness of reduction.

Laparoscopy has gained clinical acceptance in many subspecialties in the last decade. The conventional open surgery for peritonitis carries significant morbidity and mortality. The present study was done to extend and evaluate benefits of minimally invasive surgery in this subset of patients. This was a prospective study spanning over a period of four years. All those patients diagnosed as having peritonitis on clinical assessment and preoperative investigations and those who were stable enough haemodynamically were included in this study. After initial resuscitation for few hours, they underwent diagnostic and therapeutic laparoscopy to identify the cause of peritonitis and to confirm the pathology. All cases were done under general anesthesia, using three standard ports at appropriate sites according to pathology. Patients were treated by different procedures either laparoscopically or with laparoscopic assistance after diagnosis. Operative and post operative data was collected and analyzed. Ninety two cases of peritonitis underwent diagnostic and therapeutic laparoscopy. Mean age of patient was 46.5 years. 24 patients were diagnosed as perforated duodenal, in 14 (58.3%) patients laparoscopic suture repair was done and in 8 (33.3%) small upper midline incision was given and perforation was repaired. Out of 32 patients having perforated appendix, 25 (78.1%) patients laparoscopic appendectomy was done while in 7 (21.8%) perforation was dealt by laparoscopic assistance. Out of 14 patients of ileal perforation 6 (42.8%) with minimal contamination laparoscopic suture was applied, while in 8 (57.1%), perforated loop was brought out by making small window and perforation was closed. All 22 patients with pelvic sepsis needed only aspiration of pus and peritoneal lavage. Only one patient died post operatively and 2 (2.1%) patients developed fistula. 6 (6.5%) patients developed port site infection. Laparoscopic management is feasible, safe and effective surgical option for

Full Text Available Abstract Background Esophagojejunal fistula is a serious complication after total gastrectomy in gastric cancer patients. This study describes the successful conservative management in 3 gastric cancer patients with esophagojejunal fistula after total gastrectomy using total enteral nutrition. Methods Between January 2004 to December 2008, 588 consecutive patients with a proven diagnosis of gastric cancer were taken to the operation room to try a curative treatment. Of these, 173 underwent total gastrectomy, 9 of them had esophagojejunal fistula (5.2%. In three selected patients a trans-anastomotic naso-enteral feeding tube was placed under fluoroscopic vision when the fistula was clinically detected and a complete polymeric enteral formula was used. Results The complete closing of the esophagojejunal fistula was obtained in day 8, 14 and 25 respectively. Conclusion In some selected cases it is possible to make a successful enteral nutrition using a feeding tube distal to the leak area inserted with the help of fluoroscopic vision. The specialized management of a gastric surgery unit and nutritional therapy unit are highlighted.

This systematic review investigates newer generation 3-dimensional (3D) laparoscopy vs 2-dimensional (2D) laparoscopy in terms of error rating, performance time, and subjective assessment as early comparisons have shown contradictory results due to technological shortcomings. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) comparing newer generation 3D-laparoscopy with 2D-laparoscopy were included through searches in Pubmed, EMBASE, and Cochrane Central Register of Controlled Trials database. Of 643 articles, 13 RCTs were included, of which 2 were clinical trials. Nine of 13 trials (69%) and 10 of 13 trials (77%) found a significant reduction in performance time and error, respectively, with the use of 3D-laparoscopy. Overall, 3D-laparoscopy was found to be superior or equal to 2D-laparoscopy. All trials featuring subjective evaluation found a superiority of 3D-laparoscopy. More clinical RCTs are still awaited for the convincing results to be reproduced. Copyright © 2016 Elsevier Inc. All rights reserved.

Late onset of chylous ascites following distal gastrectomy with D1(+ dissection for gastric cancer: A case report

2015-12-01

Full Text Available Chyloperitoneum is the accumulation of lymphatic fluid in the peritoneal cavity. Chylous ascites can occur if it is not recognized during surgery. The incidence of chylous ascites after oncological surgery was approximately 7.4% however, the incidence of lymphorrhea after radical gastrectomy for gastric cancer is so low. Extensive lymph node dissection leads to a higher incidence of lymphorrhea. There have been few cases associated with D1 dissection In most patients conservative treatment is recommended that includes paracentesis, total parenteral nutrition (TPN, a medium chain triglyceride (MCT based diet, and somatostatin. Surgery is the last choice only when conservative treatment fails. In this case we aimed to present a late onset of chylous ascites after subtotal gastrectomy and D1+ dissection that was treated with percutaneous drainage and conservative management.

To summarize the surgical technique and perioperative management of laparoscopic sleeve gastrectomy (LSG). A total of 57 morbid obesity patients undergoing LSG surgery from May 2010 to December 2012 were enrolled in the study, whose clinical data in perioperative period were analyzed retrospectively. These patients had more than 1 year of follow-up. All the patients received preoperative preparation and postoperative management, and postoperative excess weight loss(EWL%) and improvement of preoperative complications was evaluated. All the cases completed the operation under laparoscopy, except 1 case because of the abdominal extensive adhesion. The average operation time was(102.0±15.2) min and the mean intraoperative blood loss (132.3±45.6) ml. Of 2 postoperative hemorrhage patients, 1 case received conservative treatment, and another one underwent laparoscopic exploration. The EWL% at 3 months, 6 months and 1 year after procedure was (54.9±13.8)%, (79.0±23.6)% and (106.9±25.1)% respectively. The preoperative complications were improved in some degree. There were no operative death, and anastomotic leak, anastomotic stenosis, or surgical site infection occurred. LSG is a safe and effective surgical technique, whose safety and efficacy may be increased by improving the perioperative management.

Konarzewska, J.; Bianek-Bodzak, A.; Mielcarek, P.; Kobierski, J.

2009-01-01

Background: Despite dynamic development of diagnostic imaging methods and endoscopic procedures, X-ray hysterosalpingography remains the basic diagnostic procedure when anatomical cause of infertility is suspected. The aim of the study was to assess the correlation between HSG results and laparoscopy findings, especially in infertile women with normal results of hysterosalpingography. Material/Methods: The results of HSG and laparoscopies performed between 2002 and 2005 years in 53 infertile women were analyzed retrospectively. The indication for HSG was primary infertility in 44 cases and secondary infertility in 9 cases.Results: The result of HSG was normal in 51%. Pathological findings were observed in 49% of HSG and in 93% of laparoscopies. The most common pathological findings observed during laparoscopy were tubal occlusion (26% cases) and endometriosis (25% cases). Polycystic ovaries and myomas were observed in 20% of the performed laparoscopies. HSG and laparoscopy yield consistent results in evaluation of tubal patency (p < 0.001). Conclusions: HSG remains the method of first choice in the diagnostics of uterine malformations and tubal diseases as causes of infertility. When mechanical factors of female infertility are suspected, HSG allows the optimal choice of more invasive procedure. (authors)

Three-dimensional laparoscopy: Principles and practice

Rakesh Y Sinha

2017-01-01

Full Text Available The largest challenge for laparoscopic surgeons is the eye–hand coordination within a three-dimensional (3D scene observed on a 2D display. The 2D view on flat screen laparoscopy is cerebrally intensive. The loss of binocular vision on a 2D display causes visual misperceptions, mainly loss of depth perception and adds to the surgeon's fatigue. This compromises the safety of laparoscopy. The 3D high-definition view with great depth perception and tactile feedback makes laparoscopic surgery more acceptable, safe and cost-effective. It improves surgical precision and hand–eye coordination, conventional and all straight stick instruments can be used, capital expenditure is less and recurring cost and annual maintenance cost are less. In this article, we have discussed the physics of 3D laparoscopy, principles of depth perception, and the different kinds of 3D systems available for laparoscopy. We have also discussed our experience of using 3D laparoscopy in over 2000 surgeries in the last 4 years.

To compare the levels of patient satisfaction with either conventional mandibular bilateral distal extension partial dentures or those assisted by bilateral distal implants. Forty-eight participants who were dissatisfied with their existing conventional mandibular distal extension dentures opposing complete maxillary dentures were selected for a multicentre prospective study in New Zealand, Colombia and the Netherlands. A control group of 12 participants in New Zealand received conventional mandibular partial dentures. Three test groups involving 36 participants in New Zealand (12), Colombia (12) and the Netherlands (12) received bilateral distal implants in the second molar regions. After conventional loading, the test group participants initially had healing caps placed on the distal implants providing support only, followed after approximately 6 months by ball abutments (retentive anchors) for support and retention. Patient outcomes were determined with questionnaires completed at specific stages of the study for up to 3 years. Visual analogue scale, Likert and oral health impact questionnaires before and after treatment indicated improved results. There were significantly improved parameters of overall satisfaction, stability, chewing and appearance after 3 years (P removable partial dentures are a preferable treatment option for patients with complaints about their conventional distal extension partial dentures. © 2011 John Wiley & Sons A/S.

Current less invasive surgical techniques, the use of new analgesic and anesthetic drugs, and early mobilization ("multimodal surgical strategies") reduce the occurrence of post-surgery paralytic ileus and vomiting, making possible early nutrition by the digestive route. With these premises, a nutrition protocol was designed for its implementation in colorectal pathology susceptible of laparoscopy-assisted surgery. to assess the efficacy of this protocol that comprises 3 phases. Phase I: home preparation with 7 days duration; low-residues and insoluble fiber diet, supplemented with 400 mL of hyperproteic polymeric formula with no lactose or fiber, bowel cleansing 2 days prior to surgery and hydration with water, sugared infusions, and vegetable broth. Phase II: immediate post-surgical period with watery diet for 3 days with polymeric diet with no fiber. Phase III: semi-solid diet with no residues, nutritional formula and progressive reintroduction of food intake in four stages of varying duration according to surgery and digestive tolerance. prospective study performed at our hospital with patients from our influence area, from February 2003 to May 2004, including 25 patients, 19 men and 6 women, with mean age of 63.3 years (range = 33-79) and mean body mass index of 26.25 kg/m2 (range = 20.84-31.3), all of them suffering from colorectal pathology susceptible of laparoscopy-assisted surgery, and to which the study protocol was applied. Fourteen left hemicolectomies, 5 right hemicolectomies, 4 low anterior resections with protective colostomy, and subtotal colectomies and lateral ileostomy were done. Final diagnoses were: 3 diverticular diseases; 3 adenomas; 7 rectosigmoidal neoplasms; and 12 large bowel neoplasms in other locations. The pathology study confirmed: pT3N0 (n = 7), pT3N1 (n = 3), pT3N2 (n = 1), and pT3N1M1 (n = 1), pT1N0 (n = 4), pT1N1 (n = 2), pTis (n = 1).

The Roles of Laparoscopy in Treating Ovarian Cancer

Directory of Open Access Journals (Sweden)

Chyi-Long Lee

2009-03-01

Full Text Available Great advances in technology offer meticulous options of minimally invasive surgery to empower the gynecologists to manage patients of early ovarian cancer. Laparoscopy affords improved visualization of the pelvic peritoneum, diaphragm and the deep pelvic structures, and offers many advantages in the avoidance of long abdominal incision, including shorter hospital stay and a more rapid recovery time. Most studies showed that laparoscopy did not compromise the survival and recurrence prognosis in comparison with open abdominal approach of staging surgery. Contrarily, laparoscopy precludes the advantage of open surgery, such as manual examination of the full extent of the bowel and palpation of lymph nodes. Besides, laparoscopy technically hampers the removal of large ovarian mass, and laparoscopic cancer surgery has a potential risk of trocar site metastasis. As the trend shows that laparoscopy has been playing an important role in treating early ovarian cancer, we could expect laparoscopy to become an attractive surgical option in the future for ovarian cancers.

This study aimed to evaluate the impact on perioperative and medium-term oncologic outcomes of the implementation of laparoscopy into a preexisting oncologic setting. Data from consecutive 736 patients undergoing surgery for apparent early stage gynecological malignancies (endometrial, cervical, and adnexal cancers) between 2000 and 2011 were reviewed. Complications were graded per the Accordion classification. Survival outcomes within the first 5 years were analyzed using Kaplan-Meier method. Overall, 493 (67%), 162 (22%), and 81 (11%) had surgery for apparent early stage endometrial, cervical, and adnexal cancer. We assisted at an increase of the number of patients undergoing surgery via laparoscopy through the years (from 10% in the years 2000-2003 to 82% in years 2008-2011; P 0.05). The introduction of laparoscopy did not adversely affect medium-term (within 5 years) survival outcomes of patients undergoing surgery for apparent early stage cancers of the endometrium, uterine cervix, and adnexa (P > 0.05 log-rank test). The introduction of laparoscopy into a preexisting oncologic service allows an improvement of standard of care due to a gain in perioperative results, without detriments of medium-term oncologic outcomes.

Self-Expandable Metal Stent for Closure of a Large Leak after Total Gastrectomy

2010-08-01

Full Text Available In recent years, self-expandable metallic stents (SEMSs have emerged as a promising treatment alternative for the bridging and sealing of esophageal perforations and extensive anastomotic leaks after esophageal resection or total gastrectomy. A 56-year-old woman underwent a total gastrectomy with Roux-en-Y end-to-side esophagojejunostomy for a gastric signet ring cell carcinoma. Ten days later, esophagogastroduodenoscopy showed a 2 cm fistula in the distal end of the Roux limb of the anastomosis. This was confirmed by gastrografin esophagography. The patient was started on total parenteral nutrition. Having deemed clipping treatment for this fistula unfeasible, we decided to insert a partially silicone-coated SEMS (Evolution Controlled Release Esophageal Stent System, Cook Medical, Winston-Salem, N.C., USA. The stent was removed after ten days. Gastrografin esophagography showed no further contrast extravasation, and esophagogastroduodenoscopy showed closure of the fistula. No clinical complications were observed, and the patient was able to start normal per os nutrition. In conclusion, the treatment of symptomatic leaks in patients who have undergone esophagojejunostomy is challenging, and leakage from the jejunal stump can be a potentially serious complication. In the treatment of leakage after total gastrectomy, plastic stents (which are either too light or exercise too little radial force and totally covered metallic stents may not adhere sufficiently to the esophagojeujunal walls and, as a result, migrate beyond the anastomosis. The promising results of this report suggest that early stenting, using a partially silicone-coated SEMS, is a feasible alternative to surgical treatment in this category of patients.

Studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) anastomosis are still lacking and inconsistent. The aim of this trial was to compare the quality of life (QoL) of B-I with R-Y reconstruction after curative distal gastrectomy for gastric cancer. A total of 140 patients were randomly assigned to the B-I group (N = 70) and R-Y group (N = 70) with the comparable baseline characteristics. The overall postoperative morbidity rates were 18.6% and 25.7% in the B-I group and R-Y group without significant difference. More estimated blood loss and longer surgical duration were found in the R-Y group. At the postoperative 1 year time point, the B-I group had a higher score in pain, but lower score in global health. However, the R-Y anastomosis was associated with lower incidence of reflux symptoms at postoperative 6 months (P = 0.002) and postoperative 9 months (P = 0.007). The multivariable analyses of variance did not show any interactions between the time trend and grouping. For the results of endoscopic examination, the degree and extent of remnant gastritis were milder significantly in the R-Y group. The stronger anti-reflux capability of R-Y anastomosis contributes to the higher QoL by reducing the reflux related gastritis and pain symptoms, and promotes a better global health.

Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland (HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery (LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor (SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG. PMID:26306144

Hysterectomy and laparoscopy are the two most common surgical options used to treat women with endometriosis, yet the disease may still recur. This study aimed to determine the long-term retreatment rates among endometriosis patients in the United States who received either hysterectomy or laparoscopy. Patients aged 18-49 years with endometriosis who underwent hysterectomy or laparoscopy were identified in the Truven Health MarketScan claims database (2004-2013). The retreatment rate up to 8 years after the initial surgery was estimated using Kaplan-Meier survival analysis. The relative risk of retreatment among patients with hysterectomy versus laparoscopy was assessed using a Cox proportional hazard model. A total of 24,915 patients with endometriosis who underwent hysterectomy and 37,308 patients with endometriosis who underwent laparoscopy were identified. The estimated retreatment rates were 3.3%, 4.7%, and 5.4% in the 2nd, 5th, and 8th year following hysterectomy, respectively, while the rates following laparoscopy were 15.8%, 27.5%, and 35.2%, respectively. The hazard ratio of retreatment was 0.157 (95% confidence interval [CI]: 0.146-0.169) comparing hysterectomy to laparoscopy. In the sensitivity analysis, which expanded the definition of retreatment by including medical treatments, the retreatment rate increased by a factor of 11-14 for the hysterectomy cohort and by a factor of 2-4 for the laparoscopy cohort, and the hazard ratio of retreatment rate for hysterectomy versus laparoscopy was 0.490 (95% CI: 0.477-0.502). Our study results indicated that the disease retreatment rate after laparoscopy is high among patients with endometriosis; even hysterectomy does not guarantee freedom from retreatment.

Strategic laparoscopic surgery for improved cosmesis (SLIC) is a less invasive surgical approach than conventional laparoscopic surgery. The aim of this study was to examine the feasibility and safety of SLIC for general and bariatric surgical operations. Additionally, we compared the outcomes of laparoscopic sleeve gastrectomy with those performed by the SLIC technique. In an academic medical center, from April 2008 to December 2010, 127 patients underwent SLIC procedures: 38 SLIC cholecystectomy, 56 SLIC gastric banding, 26 SLIC sleeve gastrectomy, 1 SLIC gastrojejunostomy, and 6 SLIC appendectomy. SLIC sleeve gastrectomy was initially performed through a single 4.0-cm supraumbilical incision with extraction of the gastric specimen through the same incision. The technique evolved to laparoscopic incisions that were all placed within the umbilicus and suprapubic region. There were no 30-day or in-hospital mortalities or 30-day re-admissions or re-operations. For SLIC cholecystectomy, gastric banding, appendectomy, and gastrojejunostomy, conversion to conventional laparoscopy occurred in 5.3%, 5.4%, 0%, and 0%, respectively; there were no major or minor postoperative complications. For SLIC sleeve gastrectomy, there were no significant differences in mean operative time and length of hospital stay compared with laparoscopic sleeve gastrectomy; 1 (3.8%) of 26 SLIC patients required conversion to five-port laparoscopy. There were no major complications. Minor complications occurred in 7.7% in the SLIC sleeve group versus 8.3% in the laparoscopic sleeve group. SLIC in general and bariatric operations is technically feasible, safe, and associated with a low rate of conversion to conventional laparoscopy. Compared with laparoscopic sleeve gastrectomy, SLIC sleeve gastrectomy can be performed without a prolonged operative time with comparable perioperative outcomes.

In contrast to the significant advantages of laparoscopic versus open gastrectomy, robotic gastrectomy has shown little benefit over laparoscopic gastrectomy. This study aimed to compare multi-dimensional aspects of surgical outcomes after open, laparoscopic, and robotic gastrectomy. Data from 915 gastric cancer patients who underwent gastrectomy by one surgeon between March 2009 and May 2015 were retrospectively reviewed. Perioperative parameters were analyzed for short-term outcomes. Surgical success was defined as the absence of conversion to open surgery, major complications, readmission, positive resection margin, or fewer than 16 retrieved lymph nodes. This study investigated 241 patients undergoing open gastrectomy, 511 patients undergoing laparoscopic gastrectomy, and 173 patients undergoing robotic gastrectomy. For each approach, the respective incidences were as follows: conversion to open surgery (not applicable, 0.4%, and 0%; p = 0.444), in-hospital major complications (5.8, 2.7, and 1.2%; p = 0.020), delayed complications requiring readmission (2.9, 2.0, and 1.2%; p = 0.453), positive resection margin (1.7, 0, and 0%; p = 0.003), and inadequate number of retrieved lymph nodes (0.4, 4.1, and 1.7%; p = 0.010). Compared with open and laparoscopic surgery, robotic gastrectomy had the highest surgical success rate (90, 90.8, and 96.0%). Learning-curve analysis of success using cumulative sum plots showed success with the robotic approach from the start. Multivariate analyses identified age, sex, and gastrectomy extent as significant independent parameters affecting surgical success. Surgical approach was not a contributing factor. Open, laparoscopic, and robotic gastrectomy exhibited different incidences and causes of surgical failure. Robotic gastrectomy produced the best surgical outcomes, although the approach method itself was not an independent factor for success.

Full Text Available Intrathoracic hernias after total gastrectomy are rare. We report the case of a 78-year-old man who underwent total gastrectomy with antecolic Roux-Y reconstruction for residual gastric cancer. He had alcoholic liver cirrhosis and received radical laparoscopic proximal gastrectomy for gastric cancer 3 years ago. Early gastric cancer in the remnant stomach was found by routine upper gastrointestinal endoscopy. We initially performed endoscopic submucosal dissection, but the vertical margin was positive in a pathological result. We performed total gastrectomy with antecolic Roux-Y reconstruction by laparotomy. For adhesion of the esophageal hiatus, the left chest was connected with the abdominal cavity. A pleural defect was not repaired. Two days after the operation, the patient was suspected of having intrathoracic hernia by chest X-rays. Computed tomography showed that the transverse colon and Roux limb were incarcerated in the left thoracic cavity. He was diagnosed with intrathoracic hernia, and emergency reduction and repair were performed. Operative findings showed that the Roux limb and transverse colon were incarcerated in the thoracic cavity. After reduction, the orifice of the hernia was closed by suturing the crus of the diaphragm with the ligament of the jejunum and omentum. After the second operation, he experienced anastomotic leakage and left pyothorax. Anastomotic leakage was improved with conservative therapy and he was discharged 76 days after the second operation.

Full Text Available BACKGROUND Stomach cancer is the fourth most common malignancy in the world. 1 Except in countries where screening for stomach cancer is prevalent, most of the distal stomach tumours are diagnosed at advanced stage. Gastric outlet obstruction is usually believed to be a sign of locally-advanced disease. Complete surgical removal of the disease (R0 is the only potentially curative treatment for resectable gastric cancer. The aim of the study is to finda The operability rate of gastric cancer in our institution and the incidence of Gastric Outlet Obstruction (GOO in patients undergoing gastrectomy for distal gastric cancer. b To compare the postoperative outcome in patients with gastric outlet obstruction and those without gastric outlet obstruction. c To see if the histology of the tumour has any role in the development of GOO. MATERIALS AND METHODS This is a retrospective study. The study includes patients who were admitted with carcinoma stomach and underwent operative or nonoperative treatment in our institution during 2013 to 2015. RESULTS Overall operability rate was 45.8%. Operable patients in the GOO group were 47%. Operability in the no outlet obstruction group were 45%. Data shows a slightly increased predilection for GOO in diffuse and mixed type of tumours (statistically not significant. Intestinal tumours had significant rate of anaemia compared to diffuse tumours (p <0.005. Overall mortality was 6.7%. Mortality is higher in the GOO group (8.8%. CONCLUSION (a. Operability rate of distal gastric cancer in our institution is 45.8%. (b. Incidence of gastric outlet obstruction in patients undergoing gastrectomy is 38.2%. (c. Presence of gastric outlet obstruction does not influence operability rate (47% vs. 45%. (d. Morbidity and mortality after distal radical gastrectomy is comparable in both groups. (e. Both intestinal and diffuse histology have equal incidence of GOO. (f. Chronic blood loss and incidence of anaemia is more in

Full Text Available Objective. To evaluate the safety and efficacy of a dual-lumen forward-viewing endoscope for ERCP in patients with prior Billroth II gastrectomy. Methods. The records of 46 patients treated with ERCP by a dual-lumen forward-viewing endoscope after Billroth II gastrectomy from 2007 to 2012 were reviewed. Results. The success rate of selective cannulation was 82.6% (38/46. Of the 38 cases with successful selective cannulation, endoscopic sphincterotomy was achieved in 23 cases by placing the needle knife through the 2nd lumen, while endoscopic papillary balloon dilatation was conducted in the other 15 cases. Of the 8 failed cases of selective cannulation, 6 had failed afferent loop intubation, and 3 of these 6 patients had Braun’s anastomosis. The safety and efficacy of catheter-assisted endoscopic sphincterotomy were increased by placing the needle knife through the 2nd lumen without altering the conventional endoscopic sphincterotomy procedure. Conclusions. A dual-lumen forward-viewing endoscope can be safely and effectively used to perform ERCP in patients with a Billroth II gastrectomy, except for patients with additional Braun’s anastomosis.

Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

We herein describe a case of cystic lymphangioma in the greater omentum of the remnant stomach, which is thought it to be related with subtotal gastrectomy 10 yr ago for early gastric cancer. A 76-yr-old man was admitted to our department with postprandial abdominal discomfort and bowel habit change. Intraabdominal multilocular cystic mass was detected by ultrasonography and computed tomography. We performed a complete En-bloc tumor resection including spleen and distal pancreas, and histological examination confirmed cystic lymphangioma originated from the greater omentum of the remnant stomach. Although the etiology of omental lymphangioma remains largely unclear, these findings suggested strongly that obstruction of the lymphatic vessels after gastric resection for gastric carcinoma might be the most plausible cause. The surgical extirpation with resection of organs involved appears to be a treatment of choice for such unusual case.

Aim of the study was to evaluate nutritional status in patients after gastrectomy due to gastric cancer. In 55 (26 males and 29 females) gastric cancer patients after gastrectomy body composition (bioimpedansometry method); resting energy expenditures and home actual nutrition (frequency analysis method) were evaluated. Blood levels of major nutrients and metabolites were assessed. Both men and women suffered from weight loss after gastrectomy (mean BMI was 19,8+/-4,7 kg/m2 in men and 20,5+/-1,9 in women). Higher BMI was positively correlated with age in women (R=0,45; pgastric cancer patients low BMI, low fat mass and energy consumption are observed even long period of time after gastrectomy. Dietary counseling and support are badly needed in patients short-term as well as long-term period after gastrectomy in men and younger women.

Full Text Available Abstract Situs inversus totalis (SIT is not itself a premalignant condition, however, rare synchronous or metachronous multiple primary malignancies have been reported. Herein we present a case of synchronous transverse and sigmoid colon cancers and a case of metachronous rectosigmoid colon and gastric cancers in patients with SIT. A 66-year-old male with SIT was referred for a two-month history of hematochezia. Synchronous colonic tumors were found on the proximal transverse and sigmoid colon. The patient underwent open total colectomy and was discharged without incident. A 71-year-old female with rectosigmoid colon cancer and SIT underwent laparoscopy-assisted low anterior resection. Fourteen months after the surgery, the patient developed a single hepatic metastasis and underwent hepatic segmentectomy (S6. Forty-six months after laparoscopy-assisted low anterior resection, the patient developed metachronous early gastric cancer on the antrum and underwent radical subtotal gastrectomy with gastroduodenostomy. The patient is doing well without recurrence for 28 months.

Full Text Available Objective. This prospective study evaluated laparoscopic sleeve gastrectomy for its safety and efficiency in excess weight loss (%EWL in super superobese patients (BMI >60 Kg/m2. Results. Thirty patients (33 women and 7 men were included, with mean age of 35 years (range 18 to 59. Mean preoperative BMI was 66 Kg/m2 (range 60 to 85. The study included one patient with complete situs inversus and 4 (14% with previous restrictive gastric banding. The mean operative time was 120 minutes (range 80 to 220 min and the mean hospital stay was 7.5 days (4 to 28 days. There was no postoperative mortality or need for a laparotomy conversion. Two subphrenic hematomas, one gastric fistula, and one pulmonary embolism, were the major complications. After 18 months 17 (77% had sufficient weight loss and six had insufficient results, leading to either re-sleeve gastrectomy (3, or gastric bypass (2. Three years after the initial laparoscopic sleeve gastrectomy, the mean EWL was 51% (range 21 to 82. Conclusion. The laparoscopic sleeve gastrectomy is a safe and efficient operating procedure for treating super superobesity. In the case of insufficient weight loss, a second-stage operation like resleeve gastrectomy or gastric bypass can be proposed.

Robotic-assisted laparoscopy (RAL) is being widely accepted in the field of urology as a replacement for conventional laparoscopy (CL). Nevertheless, the process of its integration in clinical routines has been rather spontaneous. To determine the prevalence of robotic systems (RS) in urological clinics in Germany, Austria and Switzerland, the acceptance of RAL among urologists as a replacement for CL and its current use for 25 different urological indications. To elucidate the practice patterns of RAL, a survey at hospitals in Germany, Austria and Switzerland was conducted. All surgically active urology departments in Germany (303), Austria (37) and Switzerland (84) received a questionnaire with questions related to the one-year period prior to the survey. The response rate was 63%. Among the participants, 43% were universities, 45% were tertiary care centres, and 8% were secondary care hospitals. A total of 60 RS (Germany 35, Austria 8, Switzerland 17) were available, and the majority (68%) were operated under public ownership. The perception of RAL and the anticipated superiority of RAL significantly differed between robotic and non-robotic surgeons. For only two urologic indications were more than 50% of the procedures performed using RAL: pyeloplasty (58%) and transperitoneal radical prostatectomy (75%). On average, 35% of robotic surgeons and only 14% of non-robotic surgeons anticipated RAL superiority in some of the 25 indications. This survey provides a detailed insight into RAL implementation in Germany, Austria and Switzerland. RAL is currently limited to a few urological indications with a small number of high-volume robotic centres. These results might suggest that a saturation of clinics using RS has been achieved but that the existing robotic capacities are being utilized ineffectively. The possible reasons for this finding are discussed, and certain strategies to solve these problems are offered. © 2015 S. Karger AG, Basel.

Robotic system has been increasingly used in pancreatectomy. However, the effectiveness of this method remains uncertain. This study compared the surgical outcomes between robot-assisted laparoscopic distal pancreatectomy and conventional laparoscopic distal pancreatectomy. During a 15-year period, 35 patients underwent minimally invasive approach of distal pancreatectomy in our center. Seventeen of these patients had robot-assisted laparoscopic approach, and the remaining 18 had conventional laparoscopic approach. Their operative parameters and perioperative outcomes were analyzed retrospectively in a prospective database. The mean operating time in the robotic group (221.4 min) was significantly longer than that in the laparoscopic group (173.6 min) (P = 0.026). Both robotic and conventional laparoscopic groups presented no significant difference in spleen-preservation rate (52.9% vs. 38.9%) (P = 0.505), operative blood loss (100.3 ml vs. 268.3 ml) (P = 0.29), overall morbidity rate (47.1% vs. 38.9%) (P = 0.73), and post-operative hospital stay (11.4 days vs. 14.2 days) (P = 0.46). Both groups also showed no perioperative mortality. Similar outcomes were observed in robotic distal pancreatectomy and conventional laparoscopic approach. However, robotic approach tended to have the advantages of less blood loss and shorter hospital stay. Further studies are necessary to determine the clinical position of robotic distal pancreatectomy.

The life-time drinking profiles of Japanese alcoholics have shown that gastrectomy increases susceptibility to alcoholism. We investigated the trends in gastrectomy and alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) genotypes and their interactions in alcoholics. This survey was conducted on 4879 Japanese alcoholic men 40 years of age or older who underwent routine gastrointestinal endoscopic screening during the period 1996-2010. ADH1B/ALDH2 genotyping was performed in 3702 patients. A history of gastrectomy was found in 508 (10.4%) patients. The reason for the gastrectomy was peptic ulcer in 317 patients and gastric cancer in 187 patients. The frequency of gastrectomy had gradually decreased from 13.3% in 1996-2000 to 10.5% in 2001-2005 and to 7.8% in 2006-2010 (P alcoholism-susceptibility genotypes, ADH1B*1/*1 and ALDH2*1/*1, modestly but significantly tended not to occur in the same individual (P = 0.026). The frequency of ADH1B*1/*1 decreased with ascending age groups. The high frequency of history of gastrectomy suggested that gastrectomy is still a risk factor for alcoholism, although the percentage decreased during the period. The alcoholism-susceptibility genotype ADH1B*1/*1 was less frequent in the gastrectomy group, suggesting a competitive gene-gastrectomy interaction for alcoholism. A gene-gene interaction and gene-age interactions regarding the ADH1B genotype were observed.

Technical Aspects of Laparoscopic Distal Pancreatectomy for Benign and Malignant Disease: Review of the Literature

Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

Enthusiasm for the use of laparoscopy in trauma has not rivaled that for general surgery. The purpose of this study was to evaluate our experience with laparoscopy at a level II trauma center. A retrospective review of all trauma patients undergoing diagnostic or therapeutic laparoscopy was performed from January 2004 to July 2010. Laparoscopy was performed in 16 patients during the study period. The average age was 35 years. Injuries included left diaphragm in 4 patients, mesenteric injury in 2, and vaginal laceration, liver laceration, small bowel injury, renal laceration, urethral/pelvic, and colon injury in 1 patient each. Diagnostic laparoscopy was performed in 11 patients (69%) with 3 patients requiring conversion to an open procedure. Successful therapeutic laparoscopy was performed in 5 patients for repair of isolated diaphragm injuries (2), a small bowel injury, a colon injury, and placement of a suprapubic bladder catheter. Average length of stay was 5.6 days (range, 0 to 23), and 75% of patients were discharged home. Morbidity rate was 13% with no mortalities or missed injuries. Laparoscopy is a seldom-used modality at our trauma center; however, it may play a role in a select subset of patients.

Full Text Available Background: the objective of our paper is to report on the long-term results of patients with gastric cancer treated by mini-invasive surgery with "intention-to-treat" laparoscopy. Patients and methods: between June 1993 and January 2006, 130 patients comprising 94 men and 36 women with gastric adenocarcinoma were prospectively selected by two surgical teams in three hospitals based on a prior agreement (CHU Charleroi, Belgium, Centre Hospitalier de Luxembourg and Zumárraga Hospital, Spain. Patients with adenocarcinoma of the cardia were excluded. Mean age of patients was 68 years (range, 37-85 years. Results: post-operative mortality within 60 days of operation was 6 patients; 109 patients were therefore properly followed up for an average of 49 months (range, 2-153 months. Average survival time for 10 non-resected patients was 4.5 months. Average survival rate for all 14 palliatively resected patients was 6.9 months. Actuarial 5-year survival rate for R0-type surgery was 35%. Global actuarial 5-year survival rate after resective surgery was 31%. Conclusions: laparoscopic gastrectomy with any kind of lymphadenectomy is a major but safe operation with acceptable mortality and morbility rates in patients with advanced gastric cancer, usually in poor general condition. Laparoscopic gastrectomy for locally advanced cancers is equivalent to laparotomy as far as long-term oncological results are concerned.

Minimally invasive techniques for gastric cancer surgery have recently been introduced in the Netherlands, based on a proctoring program. The aim of this population-based cohort study was to evaluate the short-term oncological outcomes of minimally invasive gastrectomy (MIG) during its introduction in the Netherlands. The Netherlands Cancer Registry identified all patients with gastric adenocarcinoma who underwent gastrectomy with curative intent between 2010 and 2014. Multivariable analysis was performed to compare MIG and open gastrectomy (OG) on lymph node yield (≥15), R0 resection rate, and 1-year overall survival. The pooled learning curve per center of MIG was evaluated by groups of five subsequent procedures. Between 2010 and 2014, a total of 277 (14%) patients underwent MIG and 1633 (86%) patients underwent OG. During this period, the use of MIG and neoadjuvant chemotherapy increased from 4% to 39% (p introduction of minimally invasive gastrectomy in Western countries is feasible and can be performed safely.

2018-01-01

To perform a comprehensive literature review of the incidence, location, etiology, timing, management, and long-term sequelae of urinary tract injury in gynecologic laparoscopy for benign indication. A systematic review of PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov was conducted. Four hundred thirty-three studies were screened for inclusion with 136 full-text articles reviewed. Ninety studies published between 1975 and 2015 met inclusion criteria, representing 140,444 surgeries. Articles reporting the incidence of urinary tract injury in gynecologic laparoscopy for benign indication were included. Exclusion criteria comprised malignancy, surgery by urogynecologists, research not in English, and insufficient data. A total of 458 lower urinary tract injuries were reported with an incidence of 0.33% (95% CI 0.30-0.36). Bladder injury (0.24%, 95% CI 0.22-0.27) was overall three times more frequent than ureteral injury (0.08%, 95% CI 0.07-0.10). Laparoscopic hysterectomy not otherwise specified (1.8%, 95% CI 1.2-2.6) and laparoscopically assisted vaginal hysterectomy (1.0%, 95% CI 0.9-1.2) had the highest rates of injury. Most ureteral injuries resulted from electrosurgery (33.3%, 95% CI 24.3-45.8), whereas most bladder injuries resulted from lysis of adhesions (23.3%, 95% CI 18.7-29.0). Ureteral injuries were most often recognized postoperatively (60%, 95% CI 47-76) and were repaired by open ureteral anastomosis (47.4%, 95% CI 36.3-61.9). In contrast, bladder injuries were most often recognized intraoperatively (85%, 95% CI 75-95) and were repaired by laparoscopic suturing (34.9%, 95% CI 29.2-41.7). The incidence of lower urinary tract injury in gynecologic laparoscopy for benign indication remains low at 0.33%. Bladder injury was three times more common than ureteral injury, although ureteral injuries were more often unrecognized intraoperatively and underwent open surgical repair. These risk estimates can assist gynecologic surgeons in effectively

A polycystic ovaries disease occurs in the case of women with anovulatory cycles as the result of neurohormonal disorders. Patients with this disease suffer from infertility and many symptoms, such as: irregular menstrual bleeding, hirsutism, obesity. The paper presents a method of the carbon dioxide laser laparoscopy in the polycystic ovary disease treatment. The study included 96 women operated on (carbon dioxide laser laparoscopy) in the II Clinic Of Obstetric and Gynecology in Warsaw. Each woman measured her body temperature in order to evaluate her menstrual cycle and had vaginal USG examination or a cytohormonal one before laparoscopy and within 6 months after the surgery. Performing the laparoscopy the operator punctured each ovary in at least 15 points using the carbon dioxide laser. The patients were followed-up for 6 months. The Chi test was used to make the statistic analysis. Comparing the percent of ovulatory cycles and regular ones before and after surgery we noticed that the differences were statistically relevant. Eighty-five patients (88%) had regular cycles and in 88 cases (92%) there was a diphasic curve of the body temperature after the laparoscopy. Fourteen percent of infertile women with polycystic ovary disease conceived.

Sleeve gastrectomy and gastro-oesophageal reflux disease: a complex relationship.

Science.gov (United States)

Mahawar, Kamal K; Jennings, Neil; Balupuri, Shlok; Small, Peter K

2013-07-01

Sleeve gastrectomy is rapidly becoming popular as a standalone bariatric operation. At the same time, there are valid concerns regarding its long-term durability and postoperative gastro-oesophageal reflux disease. Though gastric bypass remains the gold standard bariatric operation, it is not suitable for all patients. Sleeve gastrectomy is sometimes the only viable option. Patients with inflammatory bowel disease, liver cirrhosis, significant intra-abdominal adhesions involving small bowel and those reluctant to undergo gastric bypass could fall in this category. It is widely recognised that some patients report worsening of their gastro-oesophageal reflux disease after sleeve gastrectomy. Still, others develop de novo reflux. This review examines if it is possible to identify these patients prior to surgery and thus prevent postoperative gastro-oesophageal reflux disease after sleeve gastrectomy.

The role and application of robotic surgery are debated, particularly given the expansion of laparoscopy, especially laparoendoscopic single-site (LESS) surgery. This cohort study was undertaken to delineate differences in outcomes between LESS and robotic distal pancreatectomy and splenectomy. With Institutional Review Board approval, patients undergoing LESS or robotic distal pancreatectomy and splenectomy from September 1, 2012, through December 31, 2014, were prospectively observed, and data were collected. The results are expressed as the median, with the mean ± SD. Thirty-four patients underwent a minimally invasive distal pancreatectomy and splenectomy: 18 with robotic and 16 with LESS surgery. The patients were similar in sex, age, and body mass index. Conversions to open surgery and estimated blood loss were similar. There were two intraoperative complications in the group that underwent the robotic approach. Time spent in the operating room was significantly longer with the robot (297 vs 254 minutes, P = .03), although operative duration (i.e., incision to closure) was not longer (225 vs 190 minutes; P = .15). Of the operations studied, 79% were undertaken for neoplastic processes. Tumor size was 3.5 cm for both approaches; R0 resections were achieved in all patients. Length of stay was similar in the two study groups (5 vs 4 days). There was one 30-day readmission after robotic surgery. Patient outcomes are similar with LESS or robotic distal pancreatectomy and splenectomy. Robotic operations require more time in the operating room. Both are safe and efficacious minimally invasive operations that follow similar oncologic principles for similar tumors, and both should be in the surgeon's armamentarium for distal pancreatectomy and splenectomy.

Preserving gastric function and improving quality of life (QOL) is the tendency of surgery for early gastric cancer. Function preserving gastrectomy (FPG) is applied to modify the extent of surgery and to achieve better quality of life at the premise of radical resection. Pylorus-preserving gastrectomy is the most favorable approach of FPG with oncological safety, which can improve nutritional status and QOL via preserving pylorus and vagal nerve. Proximal gastrectomy is widely accepted as FPG for early upper 1/3 gastric cancer. However, the most optimal way of anastomosis is not yet solved. Sentinel node navigation is currently the most accurate approach for intraoperative diagnosis of lymph node metastasis, which stimulates the development of many kinds of FPG procedures for individual treatment. Nevertheless, more efforts should be made to reduce false negative rate of sentinel node biopsy. Herein we discuss the valuation and prospect of FPG.

Objective was to compare tuboperitoneal factors of infertile women hysterosalpingography (HSG) and laparoscopy. In this cohort study, 82 infertile cases were evaluated retrospectively by laparoscopy, 3 months subsequent to HSG in the Department of Gynecology and Obstetrics, Medical School of Dicle University, Diyarbakir, Turkey between March 2004 and April 2006. The findings of HSG and laparoscopy were compared. Out of 82 infertile women, pathological findings were observed in 45.1% by HSG and 54.9% had no pathological findings. On laparoscopic evaluation, however, pathological findings were observed in 65.85% and 34.15% had no pathological findings. The pathological findings were detected by laparoscopy in 20 of the 45(44.4%) patients who had had no pathological findings by HSG and no pathological findings were detected by laparoscopy in 3 of the 37 (8.1%) patients who had pathological findings by HSG. Laparoscopy revealed no pathological findings in 6 of 35 patients who had tubal pathology by HSG. The sensitivity of HSG was 63%, specificity was 89.3% and positive predictive value was 92% with a 55% predictive value and the accuracy ratio was 72%. Laparoscopy is a superior method for the result of tubal and pelvic pathologies in the evaluation of infertility. However, HSG is a more economical and elementary method suitable for evaluation of endometrial and tubal pathologies and laparoscopy is an appropriate method for examining the external part of tubae, fimbriae, the relation of tuba and ovary, endometriosis, adhesions, tuberculosis and other pathologies. Therefore, these 2 methods are not alternative but complementary. (author)

Full Text Available Introduction: Chronic pelvic pain (CPP is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 x 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%, followed by congestive dysmenorrhoea (26.7%. 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%, followed by pelvic congestion (18.6%. Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%. Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001. Adhesiolysis helps only small proportion of women in achieving pain control.

The fat, protein and B/sub 12/ absorption by the liver, kidney and, small intestine was studied by radionuclide methods in gastric cancer patients during the preoperative period as well as within 15-30 days, 3-12 months and for more than a year following gastrectomy. It was observed that the function of the kidney, liver and B/sub 12/ absorption was disturbed during the preoperative period. Gastrectomy caused a marked depression of the renal, hepatic and small intestinal function. During later periods following gastrectomy, these functions improved but were not restored to normal.

To describe a modified technique of deployment of stents using the overtube developed for balloon-assisted enteroscopy in post-sleeve gastrectomy (SG) complications. Between January 2010 and December 2015, all patients submitted to an endoscopic stenting procedure to treat a post-SG stenosis or leakage were retrospectively collected. Procedures from patients in which the stent was deployed using the balloon-overtube-assisted modified over-the-wire (OTW) stenting technique were described. The technical success, corresponding to proper placement of the stent in the stomach resulting in exclusion of the SG leak or the stenosis, was evaluated. Complications related to stenting were also reported. Five procedures were included to treat 2 staple line leaks and 3 stenoses. Two types of stents were used, including a fully covered self-expandable metal stent designed for the SG anatomy (Hanarostent, ECBB-30-240-090; M.I. Tech, Co., Ltd, Seoul, South Korea) in 4 procedures and a biodegradable stent (BD stent 019-10A-25/20/25-080, SX-ELLA, Hradec Kralove, Czech Republic) in the remaining procedure. In all cases, an overtube was advanced with the endoscope through the SG to the duodenum. After placement of the guidewire and removal of the endoscope, the stent was easily advanced through the overtube. The overtube was pulled back and the stent was successfully deployed under fluoroscopic guidance. Technical success was achieved in all patients. The adoption of a modified technique of deployment of OTW stents using an overtube may represent an effective option in the approach of SG complications.

Single-port laparoscopy is prospected as the future of minimal invasive surgery. It is hypothesised to cause less post operative pain, with a shorter hospitalisation period and improved cosmetic results. Population- and patient-based opinion is important for the adaptation of new techniques. This study aimed to assess the opinion and perception of a healthy population and a patient population on single-port laparoscopy compared with conventional laparoscopy. An anonymous 33-item questionnaire, describing conventional and single-port laparoscopy, was given to 101 patients and 104 healthy volunteers. The survey participants (median age 44 years; range 17-82 years) were asked questions about their personal situation and their expectations and perceptions of the two different surgical techniques; conventional multi-port laparoscopy and single-port laparoscopy. A total of 72% of the participants had never heard of single-port laparoscopy before. The most important concern in both groups was the risk of surgical complications. When complication risks remain similar, 80% prefers single-port laparoscopy to conventional laparoscopy. When the risk of complications increases from 1% to 10%, 43% of all participants prefer single-port laparoscopy. A total of 70% of the participants are prepared to receive treatment in another hospital if single-port surgery is not performed in their hometown hospital. The preference for single-port approach was higher in the female population. Although cure and safety remain the main concerns, the population and patients group have a favourable perception of single-port surgery. The impact of public opinion and patient perception towards innovative techniques is undeniable. If the safety of the two different procedures is similar, this study shows a positive attitude of both participant groups in favour of single-port laparoscopy. However, solid scientific proof for the safety and feasibility of this new surgical technique needs to be obtained

Acute scrotal edema is an infrequent complication in patients who undergo continuous ambulatory peritoneal dialysis (CAPD), occurring in 2% to 4% of patients. Inguinal hernia is usually the cause, but the diagnosis is sometimes confusing. Imaging modalities such as computed tomographic peritoneography are helpful but can be equivocal. We have used diagnostic laparoscopy in conjunction with open unilateral or bilateral hernia repair for diagnosis and treatment of peritoneal dialysis (PD) patients with acute scrotal edema. TECHNIQUE AND CASES: Three patients with acute scrotal edema while receiving CAPD over the span of 7 years had inconclusive results at clinical examination and on diagnostic imaging. All patients underwent diagnostic laparoscopy that revealed indirect inguinal hernia, which was concomitantly repaired using an open-mesh technique. Diagnostic laparoscopy revealed the etiology of the scrotal edema 100% of the time, with no complications, and allowed concomitant repair of the hernia. One patient had postoperative catheter outflow obstruction, which was deemed to be unrelated to the hernia repair. Diagnostic laparoscopy is helpful in confirming the source of acute scrotal edema in CAPD patients and can be performed in conjunction with an open-mesh repair with minimal added time or risk.

Laparoscopy introduction has dramatically changed urology. Novel techniques, such as laparoendoscopic single-site surgery (LESS) and natural orifice translumenal endoscopic surgery (NOTES), might also have substantial influence. This 2012 survey evaluated present laparoscopy use, its appraisal among urologic surgeons, laparoscopy training, and use of new techniques. Results were compared to the previous surveys, demonstrating the 10-year development of laparoscopy. A detailed questionnaire regarding demographic data, laparoscopy use, attitudes concerning laparoscopy, and novel techniques was send to 424 departments in Germany, Austria, and Switzerland. Procedures performed in 25 indications were quantitatively evaluated. The response rate was 63 % (269). Eighty-six percent of the respondents reported performing laparoscopy, compared to 54 % in 2002. Only 16 % expected economic advantages with laparoscopy, whereas 67 % expected shorter hospitalization. Seventy percent of responders anticipated comparable functional and oncological results between laparoscopic procedures and open surgery. Slow learning curves (81 %) and insufficient training facilities (32 %) were reported to impair laparoscopic surgery. On average, laparoscopic and non-laparoscopic surgical teams consisted of 2.5 and 3.5 members, respectively. LESS procedures were performed at 15 % of institutions. Twenty-two percent of respondents considered NOTES techniques valuable for future urology. Few indications (laparoscopic prostatectomies or nephrectomies) were performed frequently in specialized centers, and the rapidly increasing procedure numbers observed between 2002 and 2007 had dropped to a mild accretion. The results demonstrate broad acceptance of laparoscopy in German urologic surgery, depict the need for structured training facilities, and indicate limited impact of novel techniques (LESS and NOTES). The survey demonstrates the 10-year development of urologic laparoscopy and the broad acceptance

We tested our laparoscopy-assisted "open" ligation (LOL) technique on testicular vessels. We ligated the left testicular artery and vein (TAV) in 8-week-old male Wister rats using LOL (LOL group; n=10) or laparotomy (open group; n=10). In LOL, a 0-degree laparoscope was introduced through a 5-mm epigastric trocar. A 3-mm grasper was used to expose the left TAV. A lapa-her-closure (LHC) needle loaded with 3-0 SurgiPro was directly inserted into the left lower quadrant where the left TAV should be and advanced under the vessels, and the suture material was released leaving one end outside. The LHC was then withdrawn a little and advanced again over the vessels to grasp the end of the suture material just released to bring it outside. This was proximally repeated. The two ends of both sutures were conventionally tied outside, and the knot was passed through the insertion site and tightened around the vessels. In the open group, the left TAV were ligated using two 3-0 SurgiPro ties. In both groups, the right side was left intact. All rats were sacrificed 2 weeks postoperatively, and both testes were examined with hematoxylin and eosin. Treatment time was 5-7 minutes for LOL and 7-8 minutes for the open group. Postoperative recovery was uneventful. No adhesions were present between the ligated vessels and bowel in any rat. Histopathology of all left testes showed coagulative necrosis of germinal cells and seminiferous tubules; all right testes were normal. LOL appears to be as effective as open ligation and may find application for treating varicocele.

To (1) evaluate and compare computer-assisted surgery (CAS) with conventional screw insertion (conventional osteosynthesis [COS]) for treatment of equine abaxial distal phalanx fractures; (2) compare planned screw position with actual postoperative position; and (3) determine preferred screw insertion direction. Experimental study. Cadaveric equine limbs (n=32). In 8 specimens each, a 4.5 mm cortex bone screw was inserted in lag fashion in dorsopalmar (plantar) direction using CAS or COS. In 2 other groups of 8, the screws were inserted in opposite direction. Precision of CAS was determined by comparison of planned and actual screw position. Preferred screw direction was also assessed for CAS and COS. In 4 of 6 direct comparisons, screw positioning was significantly better with CAS. Results of precision analysis for screw position were similar to studies published in human medicine. None of evaluated criteria identified a preferred direction for screw insertion. For abaxial fractures of the distal phalanx, superior precision in screw position is achieved with CAS technique compared with COS technique. Abaxial fractures of the distal phalanx lend themselves to computer-assisted implantation of 1 screw in a dorsopalmar (plantar) direction. Because of the complex anatomic relationships, and our results, we discourage use of COS technique for repair of this fracture type.

Gastrectomy for gastric cancer is a significant cause of secondary exocrine pancreatic insufficiency. Pancreatic enzyme replacement therapy may influence nutritional status and quality of life after gastrectomy, but the pertinent clinical research to date remains controversial. A randomized controlled trial to test this hypothesis was carried out. After gastrectomy, 43 patients with gastric cancer were randomly assigned to a normal diet (Normal-d; n = 21) or to a pancreatic enzyme supplementation diet (PES-d; n = 22) and were followed up during a 12-month period, assessing nutritional status and quality of life through body mass index (BMI), instant nutritional assessment (INA) class status, serum pre-albumin (SPA) values, and GastroiIntestinal Quality of Life Index (GIQLI). BMI was not significantly influenced by the type of diet; INA class status was significantly improved in the PES-d arm, particularly during the first 3 months after gastrectomy; SPA levels increased in both arms at 6 months after gastrectomy, reaching significantly higher values in the PES-d arm at 12 months. GIQLI was not significantly influenced by the type of diet throughout the follow-up period; however, this index significantly improved in the PES-d arm between the first and third month after gastrectomy. PES-d improves nutritional status and quality of life after gastrectomy for gastric cancer, particularly within 3 months from the operation. A larger, multicenter trial is necessary to address the potential influence of several confounding variables such as disease stage and adjuvant treatments.

Laparoscopic techniques are evolving for a wide range of surgical procedures although they were initially confined to cholecystectomy and exploratory laparoscopy. Recently, surgical procedures performed with a laparoscope include splenectomy, adrenalectomy, gastrectomy, and myomectomy. In this article, we review the spectrum of complications and illustrate imaging features of biliary and nonbiliary complications after various laparoscopic surgeries. Biliary complications following laparoscopic cholecystectomy include bile ductal obstruction, bile leak with bile duct injury, dropped stones in the peritoneal cavity, retained CBD stone, and port-site metastasis. Nonbiliary complications are anastomotic leakage after partial gastrectomy, gangrenous cholecystitis after gastrectomy, hematoma at the anastomotic site following gastrectomy, gastric infarction after gastrectomy, port-site metastasis after gastrectomy, hematoma after splenectomy, renal infarction after adrenalectomy, and active bleeding after myomectomy of the uterus.

The impact of operative technique on outcomes in laparoscopic sleeve gastrectomy has been explored previously; however, the relative importance of patient characteristics remains unknown. Our aim was to characterize national variability in operative technique for laparoscopic sleeve gastrectomy and determine whether patient-specific factors are more critical to predicting outcomes. We queried the database of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program for laparoscopic sleeve gastrostomies performed in 2015 (n = 88,845). Logistic regression models were used to determine predictors of postoperative outcomes. In 2015, >460 variations of laparoscopic sleeve gastrectomy were performed based on combinations of bougie size, distance from the pylorus, use of staple line reinforcement, and oversewing of the staple line. Despite such substantial variability, technique variants were not predictive of outcomes, including perioperative morbidity, leak, or bleeding (all P ≥ .05). Instead, preoperative patient characteristics were found to be more predictive of these outcomes after laparoscopic sleeve gastrectomy. Only history of gastroesophageal disease (odds ratio 1.44, 95% confidence interval 1.08-1.91, P < .01) was associated with leak. Considerable variability exists in technique among surgeons nationally, but patient characteristics are more predictive of adverse outcomes after laparoscopic sleeve gastrectomy. Bundled payments and reimbursement policies should account for patient-specific factors in addition to current accreditation and volume thresholds when deciding risk-adjustment strategies.

The use of laparoscopy in blunt abdominal trauma is gaining popularity as a useful diagnostic tool to avoid unnecessary laparotomies where there is diagnostic dilemma. But the feasibility of using laparoscopy for therapeutic intervention in these patients has been debated. Even though recent case reports seem to suggest that these patients can be managed using laparoscopy, the practice is not yet wildly adopted. A retrospective analysis of a prospectively collected data was done. All adult patients who presented with abdominal trauma and were offered laparoscopic surgery at DGMAH from 2012 to 2015 were reviewed. Data was retrieved from our departmental database and analysed using descriptive statistics. A total of 318 patients were reviewed and 35 patients had blunt abdominal trauma and were included in the study. All the patients were offered laparoscopy. The median age was 30, with 91% of our patients being males. The highest injury severity score calculated was 38. At least 77% of the patients were managed using laparoscopy. This includes 43% who had both diagnostic and therapeutic intervention and 34% had only diagnostic laparoscopy. Eight patients were converted to open surgery mainly due to active bleeding and complex injuries. We did not have any non-therapeutic laparotomies, with no documented procedure related morbidity and mortality. The positive outcomes seen from the study suggest that laparoscopy can be safe and feasible in both diagnostic and therapeutic interventions in carefully selected blunt abdominal trauma patients. A conversion to open surgery should not be regarded as a failure but rather as a sign of mature and sound clinical judgement acknowledging the limitations of laparoscopy and/or the surgeon.

Full Text Available Introduction : Sleeve gastrectomy (SG continues to gain popularity as a viable weight loss procedure with well-documented outcomes and procedure-specific adverse effects. It has become increasingly indicated for the treatment of morbid obesity. Aim of the research : To compare a novel approach to SG, which aims to reduce SG-specific complications, to the standard SG procedure. Material and methods : Sixteen morbidly obese patients with a mean body mass index (BMI of 48.5 kg/m 2 ± SD who underwent the novel laparoscopic plicated sleeve gastrectomy (LPSG were retrospectively studied. The control group included 18 patients who underwent laparoscopic SG. Study and control groups were matched for BMI and gender. Study group patients underwent a partial SG with imbrication of the distal 2/3 of the staple line with 2 cm overlap and 3–4 cm of the pre-pyloric stomach. Control group SG patients had their staple line oversewn without plication. Outcomes at 3, 6 and 12 months were compared and analyzed. Results: There was no statistically significant difference in weight loss at 12 months between the LPSG and SG groups. Postoperative nausea was comparable between the two groups. No major complications were noted in either group. Conclusions: The LPSG is a modification of the standard SG which has comparable outcomes, safety and feasibility. It may lead to a decrease in unwanted complications such as sleeve stricture or obstruction. Further studies on long-term outcomes are needed to assess its value as a bariatric procedure.

Full Text Available Abstract Here we report the method of anastomosis based on double stapling technique (hereinafter, DST using a trans-oral anvil delivery system (EEATM OrVilTM for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, laparoscopic total gastrectomy employed Roux-en-Y reconstruction, laparoscopic proximal gastrectomy employed double tract reconstruction, and end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. We used EEATM OrVilTM as a device that permitted mechanical purse-string suture similarly to conventional EEA, and endo-Surgitie. After the gastric lymph node dissection, the esophagus was cut off using an automated stapler. EEATM OrVilTM was orally and slowly inserted from the valve tip, and a small hole was created at the tip of the obliquely cut-off stump with scissors to let the valve tip pass through. Yarn was cut to disconnect the anvil from a tube and the anvil head was retained in the esophagus. The end-Surgitie was inserted at the right subcostal margin, and after the looped-shaped thread was wrapped around the esophageal stump opening, assisting Maryland forceps inserted at the left subcostal and left abdomen were used to grasp the left and right esophageal stump. The surgeon inserted anvil grasping forceps into the right abdomen, and after grasping the esophagus with the forceps, tightened the end Surgitie, thereby completing the purse-string suture on the esophageal stump. The main unit of the automated stapler was inserted from the cut-off stump of the lifted jejunum, and a trocar was made to pass through. To prevent dropout of the small intestines from the automated stapler, the automated stapler and the lifted jejunum were fastened with silk thread, the abdomen was again inflated, and the lifted jejunum was led into the abdominal cavity. When it was confirmed that the automated stapler and center rod

To compare postoperative outcomes of minimally invasive gastrectomy (MIG) to open gastrectomy (OG) for cancer during the introduction of MIG in the Netherlands. Between 2011 and 2015, the use of MIG increased from 4% to 53% in the Netherlands. This population-based cohort study included all patients with curable gastric adenocarcinoma that underwent gastrectomy between 2011 and 2015, registered in the Dutch Upper GI Cancer Audit. Patients with missing preoperative data, and patients in whom no lymphadenectomy or reconstruction was performed were excluded. Propensity score matching was applied to create comparable groups between patients receiving MIG or OG, using year of surgery and other potential confounders. Morbidity, mortality, and hospital stay were evaluated. Of the 1697 eligible patients, 813 were discarded after propensity score matching; 442 and 442 patients who underwent MIG and OG, respectively, remained. Conversions occurred in 10% of the patients during MIG. Although the overall postoperative morbidity (37% vs 40%, P = 0.489) and mortality rates (6% vs 4%, P = 0.214) were comparable between the 2 groups, patients who underwent MIG experienced less wound complications (2% vs 5%, P = 0.006). Anastomotic leakage occurred in 8% of the patients after MIG, and in 7% after OG (P = 0.525). The median hospital stay declined over the years for both procedures (11 to 8 days, P Netherlands, with overall morbidity and mortality comparable with OG, less wound complications and shorter hospitalization.

Compared to aviation, where virtual reality (VR) training has been standardized and simulators have proven their benefits, the objectives, needs, and means of VR training in minimally invasive surgery (MIS) still have to be established. The aim of the study presented is to introduce Rasmussen's model of human behavior as a practical framework for the definition of the training objectives, needs, and means in MIS. Rasmussen distinguishes three levels of human behavior: skill-, rule-, and knowledge-based behaviour. The training needs of a laparoscopic novice can be determined by identifying the specific skill-, rule-, and knowledge-based behavior that is required for performing safe laparoscopy. Future objectives of VR laparoscopy trainers should address all three levels of behavior. Although most commercially available simulators for laparoscopy aim at training skill-based behavior, especially the training of knowledge-based behavior during complications in surgery will improve safety levels. However, the cost and complexity of a training means increases when the training objectives proceed from the training of skill-based behavior to the training of complex knowledge-based behavior. In aviation, human behavior models have been used successfully to integrate the training of skill-, rule-, and knowledge-based behavior in a full flight simulator. Understanding surgeon behavior is one of the first steps towards a future full-scale laparoscopy simulator.

Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

Full Text Available BACKGROUND Laparoscopy has been a new entry in the field of surgery with an active history of around just two decades. Today, it is in a position to challenge the conventional surgery which is in use since ages. It is making rapid inroads into various disciplines of surgery. Rapid improvements in optics, along with improvements in energy devices and mechanical stapling devices gave a fillip to acceptance of laparoscopy by the majority of surgeons. Also accumulating data and evidence has started influencing the sceptical, mobilising them to jump into the bandwagon. Barriers to adoption of new techniques, resistance to learning are common to human nature and it is necessary to have a systematic overview of the issues that might crop, so as to be prepared to overcome the problems of accepting laparoscopy into established centres of surgery. AIMS This publication is a reflection of our experience, our trials and tribulations in taking forward the laparoscopy program at our institution. This publication will give an overview of the steps involved in initiation of laparoscopy and aspires to be a source of answers, for day-to-day issues that crop during the process of learning laparoscopy. METHODS AND MATERIALS Just the way, executing laparoscopic surgery is a team effort, incorporating laparoscopy program in an institution is also a team effort where the members of team extend beyond the operating room. Involvement and co-operation of individuals across departments is a must along with benevolent seniors and a proactive administration. So we collated data by interviewing all the stakeholders of laparoscopy program, analysed observations of the faculty from the operating room and reviewed literature on the world wide web. Opinions of the administrators about their perceptions and the issues faced by the junior staff of the department were taken into consideration. Patients were interviewed before and after laparoscopic surgery. CONCLUSIONS Success at

Laparoscopy has become a routine procedure in the management of acute abdominal disease and can be considered both an excellent therapeutic and additional diagnostic tool in selected cases. However, a high level of expertise in laparoscopic and emergency surgery is required. Hemodynamic instability, huge abdominal distension, fecal peritonitis and perforated cancer are relative contraindications for the laparoscopic approach. In recent years, abdominal emergencies have increasingly been managed successfully by laparoscopy. In acute appendicitis, acute cholecystitis and perforated peptic ulcer, randomized controlled trials have proven that the laparoscopic approach is as safe and as effective as open surgery, with fewer complications and a quicker postoperative recovery. Other indications such as blunt and penetrating trauma to the abdomen, small bowel occlusion and perforated diverticular disease are under debate, indicating that more randomized controlled trials comparing laparoscopic and open surgery are still necessary.

Full Text Available Introduction: Laparoscopy has proved to be an important tool in the minimally invasive exploration of selected patients with chronic abdominal disorders, whose diagnosis remains uncertain, despite exploring the requisite laboratory and imaging investigations like ultrasonography, computed tomography (CT scan, and the like. Materials and Methods: Diagnostic Laparoscopy was conducted on 120 patients, admitted to the Departments of Surgery and Gynecology, Dayanand Medical College and Hospital, Ludhiana, with an uncertain diagnosis after four weeks of onset of symptoms. Conclusion: With laparoscopy providing tissue diagnosis, and helping to achieve the final diagnosis without any significant complication and less operative time, it can be safely concluded that diagnostic laparoscopy is a safe, quick, and effective adjunct to non-surgical diagnostic modalities, for establishing a conclusive diagnosis, but whether it will replace imaging studies as a primary modality for diagnosis needs more evidence.

Acute small bowel obstruction (SBO) is an urgent medical condition. Its diagnosis is based mainly on a clinical examination followed by confirmatory simple routine radiological examinations such as plain X-ray of the abdominal cavity or computed tomography (CT). However, a real surgical challenge is not a decision whether to perform a surgery, but a decision when and how to perform it. To determine the place of laparoscopy in contemporary management of acute SBO based on the current literature. A review of the literature based on the Medline database and including mainly the period of 2013-2017 was performed. With regard to SBO, laparoscopy is a technique showing its advantages resulting from a minimally invasive approach. However, SBO is still a condition where the use of laparoscopy is limited mainly to selected cases such as SBO caused by single adhesions or foreign bodies. A basic limitation of using this technique is advanced and complicated SBO and lack of sufficient technical skills of the surgeon.

Objective: To determine the necessity of using nasogastric tubes for patients with gastrectomy. Study Design: Anon-randomized controlled trial with two arms. Place and Duration of Study: Sichuan Provincial Peoples' Hospital, China, from February 2012 to January 2014. Methodology: One hundred and twenty one patients undergoing gastrectomy were assigned into intubation group and control group based on patient's own will. The intubation group was intubated with a nasogastric tube before operation and extubated at the earliest evidence of passed flatus. Clinical outcomes, such as operation time, bleeding volume, time to passage of flatus, postoperative complications, and length of stay were recorded and compared between the two groups along with patient characteristics. Results: The two groups did not differ in patient characteristics with similar distribution of gender, age, diagnosis, tumor location and operation type. Nasogastric intubation before surgery was not associated with statistically significant difference in total surgery duration, bleeding volume of operation or postoperative complications. In addition, patients without nasogastric tubes resumed oral diet earlier (52.5 ± 14.1 vs.18.4 ± 2.0 hours, p < 0.05) and had shorter time to first passage of flatus (43.8 ± 11.2 vs. 49.0 ± 13.3 hours, p=0.02). Conclusion: It is safe to give up nasogastric intubation for patients undergoing elective gastrectomy and may even result in a better patient outcome. (author)

2000-01-01

This is a report on various post-gastrectomy reconstructive procedures, proceeding from personal experience had with 14 patients undergoing gastrectomy for carcinoma of the stomach and five patients with operations of esophagus and stomach for various pathological conditions. An assessment is done of the reconstructive methods used on the ground of objective indicators. All patients are subjected to enteral alimentation through nutritive jejunostomy. In the pre- and postoperatived periods, the trophic state of patients is evaluated on basis of biochemical, anthropometric and immunologic study data. Postoperatively, in those with small-intestinal reservoir a lower degree negative symptomatology is established, along with life style improvement. Post-gastrectomy patients presenting I-II (UICC) stage of the oncological disease are indicated for small-intestinal reservoir formation. In the overall therapeutic approach to post-gastrectomy patients adequate clinical therapeutic feeding proves absolutely indispensable.

With the initiation of laparoscopic techniques in general surgery, we have seen a significant expansion of minimally invasive techniques in the last 16 years. More recently, robotic-assisted laparoscopy has moved into the general surgeon's armamentarium to address some of the shortcomings of laparoscopic surgery. AESOP (Computer Motion, Goleta, CA) addressed the issue of visualization as a robotic camera holder. With the introduction of the ZEUS robotic surgical system (Computer Motion), the ability to remotely operate laparoscopic instruments became a reality. US Food and Drug Administration approval in July 2000 of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA) further defined the ability of a robotic-assist device to address limitations in laparoscopy. This includes a significant improvement in instrument dexterity, dampening of natural hand tremors, three-dimensional visualization, ergonomics, and camera stability. As experience with robotic technology increased and its applications to advanced laparoscopic procedures have become more understood, more procedures have been performed with robotic assistance. Numerous studies have shown equivalent or improved patient outcomes when robotic-assist devices are used. Initially, robotic-assisted laparoscopic cholecystectomy was deemed safe, and now robotics has been shown to be safe in foregut procedures, including Nissen fundoplication, Heller myotomy, gastric banding procedures, and Roux-en-Y gastric bypass. These techniques have been extrapolated to solid-organ procedures (splenectomy, adrenalectomy, and pancreatic surgery) as well as robotic-assisted laparoscopic colectomy. In this chapter, we review the evolution of robotic technology and its applications in general surgical procedures.

Unexplained abdominal pain is a common but difficult presenting feature faced by the clinicians. Such patients can undergo a number of investigations with failure to reach any diagnosis. The objective of this study was to evaluate the use of laparoscopy in the diagnosis and management of patients with unexplained abdominal pain. Methods: This cross-sectional study was conducted at Pakistan Institute of Medical Sciences Islamabad from January 2009 to December 2013. This study included 91 patients of unexplained abdominal pain not diagnosed by routine clinical examination and investigations. These patients were subjected to diagnostic laparoscopy for evaluation of their conditions and to confirm the diagnosis. These patients presented 43% of patients undergoing investigations for abdominal pain. Patients diagnosed with gynaecological problems were excluded to see surgeon's perspective. The findings and the outcomes of the laparoscopy were recorded and data was analyzed. Results: Unexplained abdominal pain is common in females than in males. The most common laparoscopic findings were abdominal tuberculosis followed by appendicitis. Ninety percent patients achieved pain relief after laparoscopic intervention. Conclusion: Laparoscopy is both beneficial and safe in majority of patients with unexplained abdominal pain. General surgeons should acquire training and experience in laparoscopic surgery to provide maximum benefit to these difficult patients. (author)

There has been made an analysis of 45 cases of women's oviductal infertility qualified to surgical treatment. In search of these reasons of infertility these patients underwent hysterosalpingographic examination and 24 of them additionally, diagnostic laparoscopy with chromoturbation. Positive intraoperative verification of HSG and laparoscopy, as a confirmation of tubal obstruction, they obtained at 40 women (88.9%) that made possible to carry out microsurgical operations in them. Such a big percentage of correct diagnoses make sure, that both HSG and laparoscopy are indispensable for proper qualification of a patient to microsurgical treatment of oviductal infertility.

2017-09-25

Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

Distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. It may be potentially destructive to the abutments and the surrounding tissues. The aim of this study was to assess the effect of implant location on stress distribution, in distal extension implant assisted removable partial dentures. Three-dimensional models of a bilateral distal extension partially edentulous mandible containing anterior teeth and first premolar in both sides of the arch, a partial removable denture and an implant (4×10mm) were designed. With the aid of the finite element program ANSYS 8.0, the models were meshed and strictly vertical forces of 10 N were applied to each cusp tip. Displacement and von Mises Maps were plotted for visualization of results. When an implant was placed in the second premolar region, the highest stress on implant, abutment tooth and cancellous bone was shown. The lowest stress was shown on implant and bone in the 1(st) molar area. Implants located in the first molar area showed the least distribution of stresses in the analyzed models.

To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO). From April 2008 to April 2012, surgery-related parameters, complications, overall survival (OS), and disease-free survival (DFS) of 74 consecutive patients with left-sided CRC presented with ACO who underwent self-expandable metallic stent (SEMS) placement followed by one-stage open (n = 58) or laparoscopic resection (n = 16) were evaluated retrospectively. The stent-laparoscopy group was also compared with a control group of 96 CRC patients who underwent regular laparoscopy without ACO between January 2010 and December 2011 to explore whether SEMS placement influenced the laparoscopic procedure or reduced long-term survival by influencing CRC oncological characteristics. The characteristics of patients among these groups were comparable. The rate of conversion to open surgery was 12.5% in the stent-laparoscopy group. Bowel function recovery and postoperative hospital stay were significantly shorter (3.3 ± 0.9 d vs 4.2 ± 1.5 d and 6.7 ± 1.1 d vs 9.5 ± 6.7 d, P = 0.016 and P = 0.005), and surgical time was significantly longer (152.1 ± 44.4 min vs 127.4 ± 38.4 min, P = 0.045) in the stent-laparoscopy group than in the stent-open group. Surgery-related complications and the rate of admission to the intensive care unit were lower in the stent-laparoscopy group. There were no significant differences in the interval between stenting and surgery, intraoperative blood loss, OS, and DFS between the two stent groups. Compared with those in the stent-laparoscopy group, all surgery-related parameters, complications, OS, and DFS in the control group were comparable. The stent-laparoscopy approach is a feasible, rapid, and minimally invasive option for patients with ACO caused by left-sided CRC and can achieve a favorable long-term prognosis.

Status and Prospects of Robotic Gastrectomy for Gastric Cancer: Our Experience and a Review of the Literature

Full Text Available Since the first report of robotic gastrectomy, experienced laparoscopic surgeons have used surgical robots to treat gastric cancer and resolve problems associated with laparoscopic gastrectomy. However, compared with laparoscopic gastrectomy, the superiority of robotic procedures has not been clearly proven. There are several advantages to using robotic surgery for gastric cancer, such as reduced estimated blood loss during the operation, a shorter learning curve, and a larger number of examined lymph nodes than conventional laparoscopic gastrectomy. The increased operation time observed with a robotic system is decreasing because surgeons have accumulated experience using this procedure. While there is limited evidence, long-term oncologic outcomes appear to be similar between robotic and laparoscopic gastrectomy. Robotic procedures have a significantly greater financial cost than laparoscopic gastrectomy, which is a major drawback. Recent clinical studies tried to demonstrate that the benefits of robotic surgery outweighed the cost, but the overall results were disappointing. Ongoing studies are investigating the benefits of robotic gastrectomy in more complicated and challenging cases. Well-designed randomized control trials with large sample sizes are needed to investigate the benefits of robotic gastrectomy compared with laparoscopic surgery.

A real time ultrasonography was set up in a senegalese hospital, resulting in a decrease of laparoscopy indications. Laparoscopy is given up for the diagnosis of liver abcess, jaundice and "abdominal masses". It must no more be included in the first step check up for hepatocellular carcinoma, because ultrasonography and cytology after puncture are enough to confirm the diagnosis. Laparoscopy remains essential for peritoneal diseases. Hepatic needle biopsy under laparoscopy control remains necessary to ensure with certainty the diagnosis of cirrhosis and especially chronic hepatitis, provided that no countraindications are found.

Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant) in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.

Post-gastrectomy anastomosis site obstruction is a relatively rare complication after a subtotal gastrectomy. We present a case of a 75-year-old man who underwent a truncal vagotomy, omental patch, gastrojejunostomy, and Braun anastomosis for duodenal ulcer perforation and a gastric outlet obstruction. Following the 10(th) postoperative day, the patient complained of abdominal discomfort and vomiting. We diagnosed post-gastrectomy anastomosis site obstruction by an upper gastrointestinal series and an upper endoscopic examination. We inserted a self-expandable metallic stent (SEMS) at the anastomosis site. The stent was fully expanded after deployment. On the day following the stent insertion, the patient began to eat, and his abdominal discomfort was resolved. This paper describes the successful management of post-gastrectomy anastomosis site obstruction with temporary placement of a SEMS.

Full Text Available PURPOSE: Radical nephrectomy can be performed using open or laparoscopic (with or without hand assistance methods, and most recently using the da Vinci Surgical Robotic System. We evaluated the perioperative outcomes using a contemporary cohort of patients undergoing radical nephrectomy by one of the above 4 methods performed by the same surgeon. MATERIALS AND METHODS: The relevant clinical information on 57 consecutive patients undergoing radical nephrectomy from September 2000 until July 2004 by a single surgeon was entered in a Microsoft Access DatabaseTM and queried. Following appropriate statistical analysis, p values < 0.05 were considered significant. RESULTS: Of 57 patients, the open, robotic, laparoscopy with or without hand assistance radical nephrectomy were performed in 18, 6, 21, and 12 patients, respectively. The age, sex, body mass index (BMI, incidence of malignancy, specimen and tumor size, tumor stage, Fuhrman grade, hospital stay, change in postoperative creatinine, drop in hemoglobin, and perioperative complications were not significantly different between the methods. While the estimated median blood loss, postoperative narcotic use for pain control, and hospital stay were significantly higher in the open surgery method (p < 0.05, the median operative time was significantly shorter compared to the robotic method (p = 0.02. Operating room costs were significantly higher in the robotic and laparoscopic groups; however, there was no significant difference in total hospital costs between the 4 groups. CONCLUSIONS: The study demonstrates that radical nephrectomy can be safely performed either by open, robotic, or laparoscopic with or without hand assistance methods without significant difference in perioperative complication rates. A larger cohort and longer follow up are needed to validate our findings and establish oncological outcomes.

To evaluate the clinical value of staging laparoscopy in treatment decision-making for advanced gastric cancer (GC). Clinical data of 582 patients with advanced GC were retrospectively analyzed. All patients underwent staging laparoscopy. The strength of agreement between computed tomography (CT) stage, endoscopic ultrasound (EUS) stage, laparoscopic stage, and final stage were determined by weighted Kappa statistic (Kw). The number of patients with treatment decision-changes was counted. A χ(2) test was used to analyze the correlation between peritoneal metastasis or positive cytology and clinical characteristics. Among the 582 patients, the distributions of pathological T classifications were T2/3 (153, 26.3%), T4a (262, 45.0%), and T4b (167, 28.7%). Treatment plans for 211 (36.3%) patients were changed after staging laparoscopy was performed. Two (10.5%) of 19 patients in M1 regained the opportunity for potential radical resection by staging laparoscopy. Unnecessary laparotomy was avoided in 71 (12.2%) patients. The strength of agreement between preoperative T stage and final T stage was in almost perfect agreement (Kw = 0.838; 95% confidence interval (CI): 0.803-0.872; P advanced GC and decrease unnecessary exploratory laparotomy.

Full Text Available Background. The aim of this study was to assess the share of organic changes in patients with chronic pelvic pain (CPP as well as evaluate the need for invasive CPP diagnostics – laparoscopy.Methods. The data for the analysis were gathered retrospectively from the descriptions of 287 CPP patients who were treated at the Clinic of Gynaecology in Ljubljana from 1993 to 1999. In this analysis the share of laparoscopically established organic causes of CPP was assessed and the findings of invasive (laparoscopy and non-invasive diagnostics (clinical status and ultrasound were compared.Results. Out of 287 patients, 272 underwent laparoscopy, 7 underwent laparotomy while 8 were only observed. As regards organic CPP causes, an organic cause was established in 70.7% patients through laparoscopy. The most frequently observed phenomena were adhesions, namely in 97 (35.7% patients, endometriosis in 68 (25.0% and pelvic varices in 29 (10% patients.By comparing the results of invasive and non-invasive diagnostics it was established that up to three times more organic changes – a possible cause of CPP – can be discovered through laparoscopy than through the use of non-invasive diagnostics methods.Conclusions. Laparoscopy is considered to be the most reliable method of diagnostics and detection of organic causes of CPP. An adequate psychological treatment within a multidisciplinary approach is necessary in patients in whom an organic cause of CPP can not be discovered in their genital tract.

Epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is exceedingly rare with only 57 cases reported since the first publication in 1980. Comprehensive clinical and diagnostic features remain to be clarified. We present a case of ECIPAS in a 21-year-old Philippine woman who was admitted with right upper quadrant abdominal pain. A cystic lesion in the pancreatic tail was discovered and evaluated by computed tomography and magnetic resonance images. Based on clinical and radiological features a solid pseudopapillary neoplasm was suspected. The patient underwent robot-assisted spleen preserving distal pancreatectomy. Pathological evaluation revealed a 26 mm intrapancreatic accessory spleen with a 16 mm cyst, lined by multilayered epithelium in the tail of the pancreas. The postoperative course was uneventful. Differentiating ECIPAS from (pre)malignant cystic pancreatic neoplasms based on clinical and radiological features remains difficult. When typical radiological signs can be combined with scintigraphy using Technetium-99m labelled colloid or Technetium-99m labelled erythrocytes, which can identify the solid component of the lesion as splenic tissue, it should be possible to make the right diagnosis noninvasively. When pancreatectomy is inevitable due to symptoms or patient preference, minimally invasive laparoscopic or robot-assisted spleen preserving distal pancreatectomy should be considered.

The aim of this study was to assess the objective and subjective functional outcomes after foveal reattachment of proximal or complete ulnar-sided triangular fibrocartilage complex lesions by two surgical procedures: an open technique or an arthroscopically assisted repair. The study was done prospectively on 49 wrists affected by post-traumatic distal radio-ulnar joint instability. Twenty-four patients were treated with the open technique (Group 1) and 25 by the arthroscopically assisted technique (Group 2). Magnetic resonance imaging demonstrated a clear foveal detachment of the triangular fibrocartilage complex in 67% of the cases. Arthroscopy showed a positive ulnar-sided detachment of the triangular fibrocartilage complex (positive hook test) in all cases. Distal radio-ulnar joint stability was obtained in all but five patients at a mean follow-up of 6 months. Both groups had improvement of all parameters with significant differences in wrist pain scores, Mayo wrist score, Disability of the Arm, Shoulder and Hand questionnaire and Patient-Rated Wrist/Hand Evaluation questionnaire scores. There were no significant post-operative differences between the two groups in the outcome parameters except for the Disability of the Arm Shoulder and Hand questionnaire score, which was significantly better in Group 2 (p < 0.001). © The Author(s) 2013.

Despite proven safety and efficacy, rates of minimally invasive approaches for colon cancer remain low in the USA. Given the known benefits, investigating the root causes of underutilization and methods to increase laparoscopy is warranted. Our goal was to develop a predictive model of factors impacting use of laparoscopic surgery for colon cancer. The Premier Hospital Database was reviewed for elective colorectal resections for colon cancer (2009-2014). Patients were identified by ICD-9-CM diagnosis code and then stratified into open or laparoscopic approaches by ICD-9-CM procedure codes. An adjusted multivariate logistic regression model identified variables predictive of use of laparoscopy for colon cancer. A total of 24,245 patients were included-12,523 (52 %) laparoscopic and 11,722 (48 %) open. General surgeons performed the majority of all procedures (77.99 % open, 71.60 % laparoscopic). Overall use of laparoscopy increased from 48.94 to 52.03 % over the study period (p colon cancer laparoscopically. Colorectal surgeons were 32 % more likely to approach a case laparoscopically than general surgeons (OR 1.315, 95 % CI [1.222, 1.415], p characteristics that can be identified preoperatively to predict who will undergo surgery for colon cancer using laparoscopy. However, additional patients may be eligible for laparoscopy based on patient-level characteristics. These results have implications for regionalization and increasing teaching of MIS. Recognizing and addressing these variables with training and recruiting could increase use of minimally invasive approaches, with the associated clinical and financial benefits.

This study investigated long-term trends in hematological and nutritional parameters after gastrectomy for gastric cancer and evaluated the influence of the reconstruction type on these trends. The medical records of 558 patients who underwent curative gastrectomy with standard lymph node dissection for stage I gastric cancer between January 2006 and December 2013 were reviewed. The hematological and nutritional parameters evaluated included hemoglobin, ferritin, vitamin B 12 , total protein, albumin, total cholesterol, triglyceride, and calcium. The patients were followed up for 6 months postoperatively and then annually until death, cancer recurrence, or follow-up loss. In the long term, ferritin and triglyceride gradually decreased after gastrectomy, while the other parameters decreased slightly or were stable. In the comparisons according to reconstruction type, the Roux-en-Y group had the lowest levels of hemoglobin, ferritin, vitamin B12, total protein, albumin, and total cholesterol beginning 6 months postoperatively compared with the Billroth I and II groups. However, only ferritin and vitamin B 12 had significant differences in the 5-year cumulative incidences of deficiency/reduction according to the reconstruction type, whereas albumin, triglyceride, total cholesterol, and calcium did not. Although malabsorption and malnutrition are common in patients after a gastrectomy, most nutritional parameters were stable or decreased slightly in the long-term and were not markedly influenced by the reconstruction type or extent of gastrectomy. Therefore, for more accurate nutritional assessment after gastrectomy, multidirectional monitoring should be considered rather than simply measuring biochemical parameters.

2017-01-01

Full Text Available Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.

Laparoscopy in the management of pediatric vesicoureteral reflux

Full Text Available The prevalence of vesicoureteral reflux (VUR has been estimated as. 4 to 1.8% among the pediatric population. In children with urinary tract infection the prevalence is typically from 30-50% with higher incidence occurring in infancy. When correction of VUR is determined to be necessary, traditionally open ureteral reimplantation by a variety of techniques has been the mainstay of treatment. This approach is justified because surgical correction affords a very high success rate of 99% in experienced hands and a low complication rate. In that context the purpose of this review article is to highlight the use of laparoscopy and robot-assisted techniques to perform ureteric reimplantation for the management of pediatric VUR. A detailed review of recent literature on the subject is performed to find out various aspects of minimally invasive surgery in the treatment of VUR, highlighting evolution of management approaches, operative steps, complications, results and the current status in clinical practice. We also share our experience on the subject.

Full Text Available Distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. It may be potentially destructive to the abutments and the surrounding tissues. The aim of this study was to assess the effect of implant location on stress distribution, in distal extension implant assisted removable partial dentures.Three-dimensional models of a bilateral distal extension partially edentulous mandible containing anterior teeth and first premolar in both sides of the arch, a partial removable denture and an implant (4×10mm were designed. With the aid of the finite element program ANSYS 8.0, the models were meshed and strictly vertical forces of 10 N were applied to each cusp tip. Displacement and von Mises Maps were plotted for visualization of results.When an implant was placed in the second premolar region, the highest stress on implant, abutment tooth and cancellous bone was shown. The lowest stress was shown on implant and bone in the 1(st molar area.Implants located in the first molar area showed the least distribution of stresses in the analyzed models.

The adoption of laparoscopy for distal pancreatectomy has proven to substantially improve short-term outcomes. Stress response after major surgery can be further minimized within an enhanced recovery programme (ERP). However, data on the potential benefit of an ERP for laparoscopic distal pancreatectomy are still lacking. The aim was to assess the feasibility, safety and cost of ERP for patients undergoing laparoscopic distal pancreatectomy. This is a case-control study from a Tertiary University Hospital. Sixty-six consecutive patients who underwent laparoscopic distal pancreatectomy were analyzed. Twenty-two patients were enrolled for the ERP and compared with previous consecutive 44 patients managed traditionally (1:2 ratio). Operative details, post-operative outcome and cost analysis were compared in the two groups. Patients enrolled in the ERP had similar intraoperative blood loss (median 165 ml vs. 200 ml; p = 0.176), operation time (225 min vs. 210 min; p = 0.633), time to remove naso-gastric tube (1 vs. 1 day; p = 0.081) but significantly shorter time to mobilization (median 1 vs. 2 days; p = 0.0001), start solid diet (2 vs. 3 days; p = 0004), and pass stools (3 vs. 5 days; p = 0.002) compared to the control group. Median length of stay was significantly shorter in the ERP group (3 vs. 6 days; p pancreatectomy with significant earlier return to normal gut function, reduced length of stay and cost saving.

To study and assess clinical outcomes of various modes of treatment for perforated giant gastric ulcer in an emergency setting. From May 2010 to February 2013, 20 cases of perforated giant gastric ulcer (> 2 cm) were operated on in an emergency setting. All the patients presented with features of peritonitis and were resuscitated aggressively before taking for surgery. In the first 4 cases, primary closure was done after taking a biopsy and among these, the 3(rd) case also underwent partial distal gastrectomy and gastrojejunostomy and the 4(th) case underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy for malignancy. All the remaining 16 cases underwent partial distal gastrectomy and gastrojejunostomy. Among the first 4 cases, 2 had an uneventful recovery and were discharged on the 6(th) postoperative day. The 3(rd) and 4(th) patients developed gastric fistula, leading to prolonged hospitalization. For the 3(rd) patient, conservative management was tried for 1 wk, followed by partial distal gastrectomy and gastrojejunostomy, and he was discharged on the 20(th) day after admission, while the 4(th) patient underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy. Postoperatively, he developed adult respiratory distress syndrome, multiorgan dysfunction syndrome and expired on the 3(rd) postoperative day of the second surgery. All the remaining 16 patients underwent partial distal gastrectomy and gastrojejunostomy and recovered well. Among these, 4 of them were malignant and the remaining were benign ulcers. All had an uneventful recovery. The percentage of malignancy in our series was 30% (6 out of 20 cases). In our study, 86% had an uneventful recovery, complications were seen in about 10%, and mortality was about 5%. In giant gastric ulcer, the chances of malignancy and leak after primary closure are high. So, we feel that partial distal gastrectomy and gastrojejunostomy is better.

Retrograde Jejuno-Jejunal Intussusception after Total Gastrectomy

Directory of Open Access Journals (Sweden)

Akira Yoneda

2008-08-01

Full Text Available An eighty-year-old female was transferred to the hospital after experiencing abdominal pain and nausea. She had had a history of total gastrectomy for gastric cancer 14 years previously. Abdominal X-ray revealed a localized expansion of the small bowel. Computed tomography revealed a mass with a lamellar structure in a concentric circle. With a tentative diagnosis of small bowel obstruction due to intussusception, she underwent emergency operation. Laparotomy revealed a retrograde jejuno-jejunal intussusception. Bowel resection was performed due to the severe ischemic damage. All reported intussusception cases after total gastrectomy displayed retrograde characteristics and could occur both during the early and late period after surgery. It is important to consider the possibility of intussusception for patients presenting with acute abdomen who have previously undergone gastric resection.

Although proximal gastrectomy has become a procedure of choice for patients' early cancer in the upper third of stomach, no clinical guide for optimal gastric resection in order to avoid postoperative jejunal ulcer is available. The aim of this study was to investigate whether determining the distribution of parietal and chief cells of the stomach using Congo red test is clinically relevant. The F-line was defined as a boundary line between fundic and intermediate area of the stomach according to the pathological findings in 29 patients who underwent total gastrectomy for early gastric cancer, whereas the f-line was regarded as a boundary line between intermediate and pyloric area. In the additional 6 patients undergoing vagus-preserving proximal gastrectomy with jejunal pouch interposition, endoscopic Congo red test was preoperatively performed to determine the F-f-line. The distances from the pyloric ring to f-line on the lesser and greater curvatures were variable. Long-term outcomes of proximal gastrectomy guided by preoperative endoscopic Congo red test were favorable. It is suggested that preoperative endoscopic Congo red test is useful to determine the appropriate cutting line in order to avoid postoperative jejunal ulcer after proximal gastrectomy.

2014-04-01

Single port instrument delivery extended reach (SPIDER(®)) surgical system is a revolutionary surgical platform that allows triangulation of the surgical instruments while eliminating the crossing of instruments, the problematic characteristic of single access laparoscopic surgery. The purpose of this study was to analyze our initial experience with SPIDER(®) sleeve gastrectomy and to present the technical details of this new minimally invasive approach, performed in ten patients at the La Casamance Private Hospital between November 2012 and April 2013. All patients were reviewed at scheduled post-operative consultations at 1, 3 and 6 months. In addition to clinical examination, the post-operative consultation at one month also included a satisfaction survey using the Moorehead-Ardelt questionnaire. An initial series of ten sleeve gastrectomies were performed in female patients with a mean age of 41.5 years (range: 2-52). The mean BMI was 40.11 (range: 37.25-44.3). The intervention was performed through a single trocar in all patients with no "conversion" to classic laparoscopy or open surgery. The mean operative time was 61 ± 15.22 minutes (SD=standard deviation) (range: 43-96 min). The mean BMI at one month was 35.5 (SD:± 3.58, SEM: ± 1.13) (SEM=standard error of mean) with an average percentage of excess weight loss (%EWL) of 32.9% (SD:± 8.56%, SEM:± 2.71%). The mean BMI at three months was 32.4 (SD: ± 2.78, SEM: ± 0.88) with an average %EWL of 52.7% (SD: ± 8.64%, SEM: ± 2.73%). The mean BMI at six months was 29.9 (SD:± 2.60, SEM: ± 0.98) with a mean %EWL of 68.8% (SD: ± 8.38%, SEM:± 3.17%). Complete remission of co-morbid conditions was observed in four patients, improvement in three others, and no change in a single patient. The mean duration of hospitalization was 3.1 days. The mean follow-up period was 161 days (SD:± 57.4 days, range: 90-243 days). There was no mortality and no intra-operative and post-operative complications were noted. The

Conclusion: Minimally invasive surgery is the trend of the future. Robot-assisted laparoscopic surgery is a new technique for myomectomy. This robotic system provides a three-dimensional operative field and an easy-to-use control panel, which may be of great help when applying the suturing techniques and may shorten the learning curve. More experience with and long-term follow-up of robotic surgery may be warranted to further validate the role the robot-assisted approach in gynecologic surgery.

Full Text Available Obesity is becoming a global health burden along with its comorbidities. It imposes tremendous financial burden and health costs worldwide. Surgery has emerged as the definitive treatment option for morbidly obese patients with comorbidities. Laparoscopic sleeve gastrectomy is performed now more than ever making it imperative for physicians and surgeons to recognize both the common and the uncommon risks and complications associated with it. In this report we describe a rare early life-threatening postoperative complication following laparoscopic sleeve gastrectomy. From our extensive review of literature, there is no existing report of acute pancreatitis with splenic infarction postsleeve gastrectomy to this date.

Abstract Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables. One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications. Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP. There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results. PMID:28422853

A 76-year-old man was admitted to our hospital for treatment of gastric tube cancer(cT2N0M0, cStage II A)detected by a screening upper gastrointestinal endoscopy. Seven years previously, he had undergone subtotal esophagectomy for esophageal cancer with gastric pull-up via the retrosternal route. At that time, he experienced cardiopulmonary arrest due to ventric- ular tachycardia. He was in a state of poor nutrition(BMI 15 kg/m2). Therefore, reducing operative stress as much as possible, minimizing complications after surgery, and aiming for a satisfactory postoperative course are all important goals. Based on his past history, we performed distal gastrectomy(resection of the distal part of the gastric tube)without excision of the right gastroepiploic artery. The postoperative course was uneventful. He was discharged 40 days after surgery. By considering the risks of surgery due to cardiac dysfunction and malnutrition, we were able to provide effective and safe therapy for the patient.

OBJECTIVE To evaluate the feasibility of laparoscopy versus exploratory laparotomy for the diagnosis of specific lesions in dogs with suspected gastrointestinal obstruction. DESIGN Controlled trial. ANIMALS 16 client-owned dogs with physical and radiographic findings consistent with gastrointestinal obstruction. PROCEDURES Single-incision laparoscopy with intracorporeal and extracorporeal examination of the gastrointestinal tract was performed by 1 surgeon. Immediately afterward, exploratory laparotomy was performed by a second surgeon. Accessibility and gross appearance of organs, surgical diagnoses, incision lengths, procedure duration, and complications were compared between diagnostic techniques. RESULTS Mean (95% confidence interval) incision length was 4.9 cm (3.9 to 5.9 cm) for laparoscopy and 16.4 cm (14.0 to 18.7 cm) for exploratory laparotomy. Mean (95% confidence interval) procedure duration was 36.8 minutes (31.6 to 41.2 minutes) and 12.8 minutes (11.4 to 14.3 minutes), respectively. Diagnoses of the cause of obstruction were the same with both methods. In 13 dogs, the laparoscopic examination was successfully completed, and in the other 3, it was incomplete. In 4 dogs in which laparoscopy was successful, conversion to exploratory laparotomy or considerable extension of the laparoscopic incision would have been required to allow subsequent surgical treatment of identified lesions. No dogs developed major complications, and minor complication rates were similar between procedures. CONCLUSIONS AND CLINICAL RELEVANCE Laparoscopy was feasible and clinically applicable in dogs with suspected gastrointestinal obstruction. Careful patient selection and liberal criteria for conversion to an open surgical approach are recommended when laparoscopy is considered for the diagnosis of gastrointestinal lesions in dogs.

The indications for sleeve gastrectomy as a primary procedure for the surgical treatment of morbid obesity have increased worldwide. Pain is the most common complaint for patients on the first day after laparoscopic sleeve gastrectomy. There are various methods for decreasing pain after laparoscopic sleeve gastrectomy such as the use of intraperitoneal bupivacaine hydrochloride. This clinical trial was an attempt to discover the effects of intraperitoneal bupivacaine hydrochloride on alleviating postoperative pain after laparoscopic sleeve gastrectomy. In general, 120 patients meeting the inclusion criteria were enrolled. Patients were randomly allocated into two interventions and control groups using a balanced block randomization technique. One group received intraperitoneal bupivacaine hydrochloride (30 cm 3 ), and the other group served as the control one and did not receive bupivacaine hydrochloride. Diclofenac suppository and paracetamol injection were administered to both groups for postoperative pain management. The mean subjective postoperative pain score was significantly decreased in patients who received intraperitoneal bupivacaine hydrochloride within the first 24 h after the surgery; thus, the instillation of bupivacaine hydrochloride was beneficial in managing postoperative pain. The intraoperative peritoneal irrigation of bupivacaine hydrochloride (30 cm 3 , 0.25%) in sleeve gastrectomy patients was safe and effective in reducing postoperative pain, nausea, and vomiting (IRCT2016120329181N4).

Woo, Sung Jong; Jegal, Midum; Park, Min Jong

2016-01-01

Background: Disruption of the triangular fibrocartilage complex (TFCC) foveal insertion can lead to distal radioulnar joint (DRUJ) instability accompanied by ulnar-sided pain, weakness, snapping, and limited forearm rotation. We investigated the clinical outcomes of patients with TFCC foveal tears treated with arthroscopic-assisted repair. Materials and Methods: Twelve patients underwent foveal repair of avulsed TFCC with the assistance of arthroscopy between 2011 and 2013. These patients were followed up for an average of 19 months (range 14–25 months). The avulsed TFCC were reattached to the fovea using a transosseous pull-out suture or a knotless suture anchor. At the final followup, the range of motion, grip strength and DRUJ stability were measured as objective outcomes. Subjective outcomes were assessed using the Visual Analog Scale (VAS) for pain, patient rated wrist evaluation (PRWE), Disabilities of the Arm, Shoulder and Hand questionnaire (DASH score) and return to work. Results: Based on the DRUJ stress test, 5 patients had normal stability and 7 patients showed mild laxity as compared with the contralateral side. Postoperatively, the mean range of pronation supination increased from 141° to 166°, and the mean VAS score for pain decreased from 5.3 to 1.7 significantly. The PRWE and DASH questionnaires also showed significant functional improvement. All patients were able to return to their jobs. However, two patients complained of persistent pain. Conclusions: Arthroscopically assisted repair of TFCC foveal injury can provide significant pain relief, functional improvement and restoration of DRUJ stability. PMID:27293286

We evaluate the feasibility and efficacy of combination chemotherapy including single intraperitoneal( IP)administration of paclitaxel(PTX), followed by triplet chemotherapy(PTX, cisplatin[CDDP]and S-1: PCS)for CY1P0 gastric cancer. First of all, we performed staging laparoscopy and confirmed CY1P0, and secondary, administrated PTX intraperitoneally. Thirdly, patients received PCS chemotherapy for 2 courses. After antitumor effect had been confirmed, we performed second look laparoscopy. In the case of CY0P0, we performed gastrectomy with D2 lymph nodes dissection. Total 4 patients were enrolled. Grade 3 leukopenia and neutropenia were observed in one patient while intraperitoneal and systemic-chemotherapy. One patients showed PR and 3 patients showed SD. All patients underwent second look laparoscopy. CY0P0 was observed in all patients and gastrectomy with D2 dissection was performed for all patients. Postoperative complications were observed in 2 patients. Two patients were still alive without recurrence, while the remaining 2 had died of liver metastasis and #16 LN metastasis. Combination chemotherapy including single IP PTX followed by PCS systemic-chemotherapy for CY1P0 gastric cancer is feasible and efficient.

Diagnostic laparoscopy (DL) is a well-accepted approach for penetrating abdominal trauma (PAT). However, the steps of procedure and the systematic laparoscopic examination are not clearly defined in the literature. The aim of this study was to clarify the definition of DL in trauma surgery by auditing DL performed for PAT at our institution, and to describe the strategies on how to avoid missed injuries. The data of patients managed with laparoscopy for PAT from January 2012 to December 2015 were retrospectively analyzed. The details of operative technique and strategies on how to avoid missed injuries were discussed. Out of 250 patients managed with laparoscopy for PAT, 113 (45%) patients underwent DL. Stab wounds sustained 94 (83%) patients. The penetration of the peritoneal cavity or retroperitoneum was documented in 67 (59%) of patients. Organ evisceration was present in 21 (19%) patients. Multiple injuries were present in 22% of cases. The chest was the most common associated injury. Two (1.8%) iatrogenic injuries were recorded. The conversion rate was 1.7% (2/115). The mean length of hospital stay was 4 days. There were no missed injuries. In the therapeutic laparoscopy (TL) group, DL was performed as the initial part and identified all injuries. There were no missed injuries in the TL group. The predetermined sequential steps of DL and the standard systematic examination of intraabdominal organs were described. DL is a feasible and safe procedure. It accurately identifies intraabdominal injuries. The selected use of preoperative imaging, adherence to the predetermined steps of procedure and the standard systematic laparoscopic examination will minimize the rate of missed injuries.

Endoscopic stenting is a relatively new technique for the treatment of post sleeve gastrectomy complications. Partially covered stents are used in this method to minimise the risk of migration but they are associated with difficulties with removal. Patients requiring emergency stenting following sleeve gastrectomy underwent insertion of a partially covered metallic stent. One month later, if the stent was not easily removable, a fully covered overlapping stent was inserted and the patient was readmitted 2 weeks later for removal of both stents. Four patients required stenting following sleeve gastrectomy leaks, and one patient required stenting for a stricture. In these cases, a 'stent in a stent' technique was used for removal. This technique allows the safe removal of partially covered stents inserted following sleeve gastrectomy complications.

Chronic abdominal pain after bariatric surgery is associated with diagnostic and therapeutic challenges. The aim of this study was to evaluate the yield of laparoscopy as a diagnostic and therapeutic tool in post-bariatric surgery patients with chronic abdominal pain who had negative imaging and endoscopic studies. A retrospective analysis was performed on post-bariatric surgery patients who underwent laparoscopy for diagnosis and treatment of chronic abdominal pain at a single academic center. Only patients with both negative preoperative CT scan and upper endoscopy were included. Total of 35 post-bariatric surgery patients met the inclusion criteria, and all had history of Roux-en-Y gastric bypass. Twenty out of 35 patients (57%) had positive findings on diagnostic laparoscopy including presence of adhesions (n = 12), chronic cholecystitis (n = 4), mesenteric defect (n = 2), internal hernia (n = 1), and necrotic omentum (n = 1). Two patients developed post-operative complications including a pelvic abscess and an abdominal wall abscess. Overall, 15 patients (43%) had symptomatic improvement after laparoscopy; 14 of these patients had positive laparoscopic findings requiring intervention (70% of the patients with positive laparoscopy). Conversely, 20 (57%) patients required long-term medical treatment for management of chronic abdominal pain. Diagnostic laparoscopy, which is a safe procedure, can detect pathological findings in more than half of post-bariatric surgery patients with chronic abdominal pain of unknown etiology. About 40% of patients who undergo diagnostic laparoscopy and 70% of patients with positive findings on laparoscopy experience significant symptom improvement. Patients should be informed that diagnostic laparoscopy is associated with no symptom improvement in about half of cases.

The relation between hunger, satiation, and integrated gastrointestinal motility and hormonal responses in morbidly obese patients after sleeve gastrectomy has not been determined. The objective was to assess the effects of sleeve gastrectomy on hunger, satiation, gastric and gallbladder motility, and gastrointestinal hormone response after a liquid meal test. Three groups were studied: morbidly obese patients (n = 16), morbidly obese patients who had had sleeve gastrectomy (n = 8), and nonobese patients (n = 16). The participants fasted for 10 h and then consumed a 200-mL liquid meal (400 kcal + 1.5 g paracetamol). Fasting and postprandial hunger, satiation, hormone concentrations, and gastric and gallbladder emptying were measured several times over 4 h. No differences were observed in hunger and satiation curves between morbidly obese and nonobese groups; however, sleeve gastrectomy patients were less hungry and more satiated than the other groups. Antrum area during fasting in morbidly obese patients was statistically significant larger than in the nonobese and sleeve gastrectomy groups. Gastric emptying was accelerated in the sleeve gastrectomy group compared with the other 2 groups (which had very similar results). Gallbladder emptying was similar in the 3 groups. Sleeve gastrectomy patients showed the lowest ghrelin concentrations and higher early postprandial cholecystokinin and glucagon-like peptide 1 peaks than did the other participants. This group also showed an improved insulin resistance pattern compared with morbidly obese patients. Sleeve gastrectomy seems to be associated with profound changes in gastrointestinal physiology that contribute to reducing hunger and increasing sensations of satiation. These changes include accelerated gastric emptying, enhanced postprandial cholecystokinin and glucagon-like peptide 1 concentrations, and reduced ghrelin release, which together may help patients lose weight and improve their glucose metabolism after

The purpose of this prospective study was to investigate changes in lipid indices associated with whole body composition during 1 year of follow-up after laparoscopic gastrectomy. Thirty-seven patients with benign and malignant gastric neoplasm who underwent laparoscopic gastrectomy were prospectively enrolled. None of the patients were treated with adjuvant chemotherapy. Lipid indices and body composition were measured preoperatively and at six and 12 months after laparoscopic gastrectomy. Lipid indices included total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). Body weight, fat and lean body mass (LBM) were measured by dual-energy X-ray absorptiometry and the change in fat and LBM in the trunk, arms and legs was compared. Body weight significantly decreased from 63.0 ± 11.1 kg preoperatively to 56.8 ± 10.6 kg 12 months after laparoscopic gastrectomy, with a mean of 7.1% (4.6 kg) weight loss. Fat and LBM loss contributed 68.4% (3.1 kg) and 30.1% (1.4 kg) of the total weight loss, respectively. In both the non-obese and obese groups, body weight, fat and LBM did not change significantly between 6 months and 12 months after gastrectomy. TC and LDL-C levels significantly decreased during the first six-month period and HDL-C significantly increased until 12 months after gastrectomy in the non-obese group. In the obese group, the degree of reduction in fat mass was significantly higher and the LBM/weight ratio significantly increased compared with the non-obese group. However, there was no significant change in lipid indices in the obese group. The TG level was significantly correlated with fat, especially with trunk fat. Gastrectomy resulted in improved lipid indices and a reduction in body weight, fat and LBM. The HDL-C significantly increased in the non-obese group for 1 year after gastrectomy and the reduction of TG level was positively correlated with fat

Laparoscopic sleeve gastrectomy is a safe and effective bariatric operation, but postoperative reflux symptoms can sometimes necessitate revisional surgery. Roux-en-Y gastric bypass is the preferred operation in morbidly obese patients with gastro-oesophageal reflux disease. In 2011, we introduced preoperative endoscopy to assess for hiatus hernia or evidence of oesophagitis in conjunction with an assessment of gastro-oesophageal reflux symptoms for all patients undergoing bariatric surgery with a view to avoid sleeve gastrectomy for these patients. A prospectively maintained database was used to identify patients who underwent sleeve gastrectomy before and after we changed the unit policy. The need for revisional surgery in patients with troublesome gastro-oesophageal reflux disease was examined. Prior to 2011, 130 patients underwent sleeve gastrectomy, and 11 (8.5%) of them required conversion to Roux-en-Y gastric bypass for symptomatic reflux disease. Following the policy change, 284 patients underwent sleeve gastrectomy, and to date, only five (1.8%) have required revisional surgery (p = 0.001). Baseline demographics were comparable between the groups, and average follow-up period was 47 and 33 months, respectively, for each group. Preoperative endoscopy and a detailed clinical history regarding gastro-oesophageal reflux symptoms may improve patient selection for sleeve gastrectomy. Avoiding sleeve gastrectomy in patients with reflux disease and/or hiatus hernia may reduce the incidence of revisional surgery. © 2016 World Obesity.

The totally laparoscopic approach to partial gastrectomy had not been compared previously with results of the open technique. This study compares the results of a series of laparoscopic cases with matched open cases. A retrospective case-matched study was performed in 36 patients (18 laparoscopic surgeries, 18 open surgeries). Each laparoscopic case was matched for patient age and indication for surgery. The intraoperative and postoperative details of the two groups were compared. Laparoscopic surgery resulted in less blood loss, although operative time was increased. Nasogastric tubes were less likely to be used after laparoscopic surgery, and patients in the laparoscopic group had an earlier return to normal bowel function than those in the open group. Length of hospital stay was 2 days shorter in the laparoscopic group. The totally laparoscopic approach to partial gastrectomy is an excellent alternative to the more traditional open approach. It results in a more rapid return of intestinal function and a shorter hospital stay.

Over the past 2 decades, laparoscopy has been established as a superior technique in many general surgery procedures. Few studies, however, have examined the impact of the use of a laparoscopic approach in patients with symptomatic congestive heart failure (CHF). Because pneumoperitoneum has known effects on cardiopulmonary physiology, patients with CHF may be at increased risk. This study examines current trends in approaches to patients with CHF and effects on perioperative outcomes. The 2005-2011 National Surgical Quality Improvement Program Participant User File was used to identify patients who underwent the following general surgery procedures: Appendectomy, segmental colectomy, small bowel resection, ventral hernia repair, and splenectomy. Included for analysis were those with newly diagnosed CHF or chronic CHF with new signs or symptoms. Trends of use of laparoscopy were assessed across procedure types. The primary endpoint was 30-day mortality. The independent effect of laparoscopy in CHF was estimated with a multiple logistic regression model. A total of 265,198 patients were included for analysis, of whom 2,219 were identified as having new or recently worsened CHF. Of these patients, there were 1,300 (58.6%) colectomies, 486 (21.9%) small bowel resections, 216 (9.7%) ventral hernia repairs, 141 (6.4%) appendectomies, and 76 (3.4%) splenectomies. Laparoscopy was used less frequently in patients with CHF compared with their non-CHF counterparts, particularly for nonelective procedures. Baseline characteristics were similar for laparoscopy versus open procedures with the notable exception of urgent/emergent case status (36.4% vs 71.3%; P surgery procedures, particularly in urgent/emergent cases. Despite these patterns and apparent preferences, laparoscopy seems to offer a safe alternative in appropriately selected patients. Because morbidity and mortality were considerable regardless of approach, further understanding of appropriate management in this

The optimal intraperitoneal pressure during laparoscopy is not known. Recent literature found benefits of using lower pressures, but the safety of doing abdominal surgery with low peritoneal pressures needs to be assessed. This systematic review compares low with standard pneumoperitoneum during gynecologic laparoscopy. We searched Medline, Embase, and the Cochrane Library for randomized controlled trials comparing intraperitoneal pressures during gynecologic laparoscopy. Two authors reviewed references and extracted data from included trials. Risk ratios, mean differences, and standard mean differences were calculated and pooled using RevMan5. Of 2251 studies identified, three were included in the systematic review, for a total of 238 patients. We found a statistically significant but modest diminution in postoperative pain of 0.38 standardized unit based on an original 10-point scale (95% confidence interval [CI], -0.67 to -0.08) during the immediate postoperative period when using low intraperitoneal pressure of 8 mm Hg compared with ≥ 12 mm Hg and of 0.50 (95% CI, -0.80 to -0.21) 24 hours after the surgery. Lower pressures were associated with worse visualization of the surgical field (risk ratio, 10.31; 95% CI, 1.29-82.38). We found no difference between groups over blood loss, duration of surgery, hospital length of stay, or the need for increased pressure. Low intraperitoneal pressures during gynecologic laparoscopy cannot be recommended on the behalf of this review because improvement in pain scores is minimal and visualization of the surgical field is affected. The safety of this intervention as well as cost-effectiveness considerations need to be further studied.

The aim of this study was to describe postoperative outcomes of total gastrectomy at our institution for patients with hereditary diffuse gastric cancer (HDGC). HDGC, which is mainly caused by germline mutations in the E-cadherin gene (CDH1), renders a lifetime risk of gastric cancer of up to 70%, prompting a recommendation for prophylactic total gastrectomy. A prospective gastric cancer database identified 41 patients with CDH1 mutation who underwent total gastrectomy during 2005 to 2015. Perioperative, histopathologic, and long-term data were collected. Of the 41 patients undergoing total gastrectomy, median age was 47 years (range 20 to 71). There were 14 men and 27 women, with 25 open operations and 16 minimally invasive operations. Median length of stay was 7 days (range 4 to 50). In total, 11 patients (27%) experienced a complication requiring intervention, and there was 1 peri-operative mortality (2.5%). Thirty-five patients (85%) demonstrated 1 or more foci of intramucosal signet ring cell gastric cancer in the examined specimen. At 16 months median follow-up, the median weight loss was 4.7 kg (15% of preoperative weight). By 6 to 12 months postoperatively, weight patterns stabilized. Overall outcome was reported to be "as expected" by 40% of patients and "better than expected" by 45%. Patient-reported outcomes were similar to those of other patients undergoing total gastrectomy. Total gastrectomy should be considered for all CDH1 mutation carriers because of the high risk of invasive diffuse-type gastric cancer and lack of reliable surveillance options. Although most patients have durable weight loss after total gastrectomy, weights stabilize at about 6 to 12 months postoperatively, and patients report outcomes as being good to better than their preoperative expectations. No patients have developed gastric cancer recurrence after resections.

Staple line leak is a serious complication of sleeve gastrectomy. Intraoperative methylene blue and air leak tests are routinely used to evaluate for leak; however, the utility of these tests is controversial. We hypothesize that the practice of routine intraoperative leak testing is unnecessary during sleeve gastrectomy. A retrospective cohort study was designed using a prospectively collected database of seven bariatric surgeons from two institutions. All patients who underwent sleeve gastrectomy from March 2012 to November 2014 were included. The performance of intraoperative leak testing and the type of test (air or methylene blue) were based on surgeon preference. Data obtained included BMI, demographics, comorbidity, presence of intraoperative leak test, result of test, and type of test. The primary outcome was leak rate between the leak test (LT) and no leak test (NLT) groups. SAS version 9.4 was used for univariate and multivariate analyses. A total of 1550 sleeve gastrectomies were included; most were laparoscopic (99.8%), except for one converted and two open cases. Routine intraoperative leak tests were performed in 1329 (85.7%) cases, while 221 (14.3%) did not have LTs. Of the 1329 cases with LTs, there were no positive intraoperative results. Fifteen (1%) patients developed leaks, with no difference in leak rate between the LT and NLT groups (1 vs. 1%, p = 0.999). After adjusting for baseline differences between the groups with a propensity analysis, the observed lack of association between leak and intraoperative leak test remained. In this cohort, leaks presented at a mean of 17.3 days postoperatively (range 1-67 days). Two patients with staple line leaks underwent repeat intraoperative leak testing at leak presentation, and the tests remained negative. Intraoperative leak testing has no correlation with leak due to laparoscopic sleeve gastrectomy and is not predictive of the later development of staple line leak.

Chronic abdominal Pain in children is a very common cause of hospital admission. Many of them are discharged without a diagnosis even after battery of investigations. Laparoscopy plays a significant role in diagnosis and management of many causes of acute and chronic abdominal pain. The purpose of this study was to determine the efficacy of laparoscopy as an efficient diagnostic and management tool in children with chronic abdominal pain. A descriptive, prospective case series was collected in the department of Paediatric surgery Mayo's Hospital Lahore, over the period of 5 years between Jan 2007-Dec 2013. The data of consecutive 50 patients, who were admitted in the department with the diagnosis of chronic abdominal pain, was recorded. All patients who had 2-3 admissions in hospital for last 2 months and failed to establish a definitive diagnosis after clinical examination and base line investigations underwent laparoscopy. The details of associated symptoms, finding of laparoscopy, laparoscopic procedures done, definitive diagnosis, histopathology, complications and relief of symptoms were collected and analysed and results were evaluated using SPSS-17. Out of 50 patients studies, 27/50 (54%) were male, 23/50 (46%) were female. Age ranged from 2-12 years, with the mean age of 7.24 year. Tuberculosis abdomen, adhesions, mesenteric lymphadenitis, appendicitis and cholecystitis were the final diagnosis. Five abdomens were found normal on laparoscopy. Complete pain relief was achieved in 30/50 (60%), reduced intensity of pain was gained in 12/50 (24%) cases while 16% (8/50) still complained of pain. Laparoscopy is an efficient diagnostic and treatment tool in children with chronic unexplained abdominal pain. It avoids serial examinations; prolong admission, battery of investigations and unnecessary surgeries.

Laparoscopic sleeve gastrectomy (LSG) is widely adopted but exposes serious complications. A retrospective database analysis was done to study LSG staple line complications in a tertiary referral university center with surgical ICU experienced in treatment of morbid obesity and complications. Twenty-two consecutive patients were referred between January 2004 and February 2012 with postoperative gastric leak or stenosis after LSG. Interventions consisted in the control of intra-abdominal and general sepsis; restoration of staple line continuity or revision of LSG; nutritional support; treatment of associated complications. Main outcome measures concerned success rates of therapeutic strategies, morbidity and mortality rates, LOS, and time to cure. Thirteen patients (59 %) were referred after failure of reoperation (seven fistula repairs were attempted). Three patients received emergency surgery in our center with transorificial intubation and jejunostomy formation. An endoscopic stent was tried in nine patients but failed in 84.6 % of cases within 20 days (1-161). Seven patients (32 %) necessitated total gastrectomy within 217 days (0-1,915 days) for conservative treatment failure. Procedures under general anesthesia were required in 41 % of cases, organ failure was found in 55 % of cases, and central venous device infection in 40 %. Mortality rate was 4.5 % (n = 1). Patients with unfavorable evolution of LSG complications (death or additional gastrectomy) had more previous bariatric procedure (82 % vs. 18 %, p = 0.003). Median time to cure was 310 days (9-546 days). LSG exposes severe complications occurring in patients with benign condition. Endoscopic stents entail high failure rate. Total gastrectomy is required in one third of the cases.

An unusual case of intra-abdominal testicular torsion: Role of laparoscopy

Full Text Available The authors report a case of intra-abdominal testicular torsion, where laparoscopy has been useful for diagnosis and surgical management. A boy was presented with a left impalpable testis. Laparoscopy revealed a twisted spermatic cord at the inlet pelvis, which ended in a testicular remnant located in the sub-umbilical area. After orchiectomy, the pathologist confirmed testicular atrophy. Diagnosis of intra-abdominal testicular torsion should be considered in patients with impalpable testis and abdominal pain, but could not be excluded in those with no symptoms.

Aims To investigate the feasibility and safety of endoscopic submucosal dissection (ESD) of gastric epithelial neoplasms in the remnant stomach (GEN-RS) after various types of partial gastrectomy. Methods This study included 29 patients (31 lesions) who underwent ESD for GEN-RS between March 2006 and August 2016. Clinicopathologic data were retrieved retrospectively to assess the therapeutic ESD outcomes, including en bloc and complete resection rates and procedure-related adverse events. Results The en bloc, complete, and curative resection rates were 90%, 77%, and 71%, respectively. The types of previous gastrectomy, tumor size, macroscopic type, and tumor histology were not associated with incomplete resection. Only tumors involving the suture lines from the prior partial gastrectomy were significantly associated with incomplete resection. The procedure-related bleeding and perforation rates were 6% and 3%, respectively; none of the adverse events required surgical intervention. During a median follow-up period of 25 months (range, 6–58 months), there was no recurrence in any case. Conclusions ESD is a safe and feasible treatment for GEN-RS regardless of the previous gastrectomy type. However, the complete resection rate decreases for lesions involving the suture lines.

Gastric cancer is one of the most frequent causes of death secondary to cancer in the world. Surgery is the only potentially curative treatment but its clinical consequences are significant. The objective of this study is to evaluate the nutritional state of patients with a total gastrectomy secondary to gastric adenocarcinoma. We designed a descriptive study with a transversal cut in our institution. We included 22 patients which had a minimum evolution time of six months after total gastrectomy secondary to gastric cancer surgery was performed. Neither of them had metastasis. The nutritional analysis included only biochemical data. Descriptive statistics were used for statistical analysis. Eight females and 14 males were included in the study. Median age was 57 years (34 - 69 years). The 74% of the patients were underweight and none of them was overweight. The average body mass index (BMI) was 16.88 kg/m 2 . Eleven patients suffered from mild anemia (10.5 - 12 g/dl) and 5 from moderate anemia (9 - 10.5 g/dl). Only two patients presented severe anemia (less than 9 g/dl). The 58% presented hypoproteinaemia and hypoalbuminaemia. The main post-surgery complication was nausea (46%). Seventy-eight percent of the patients had loss of appetite. Twenty-one patients were able to walk without help and leave their homes. The incidence of anemia in these patients was very high. In most of the patients, albumin and proteins levels were affected too. So malnutrition was a relevant consequence of a total gastrectomy.

Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy. A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Gastric cancer in remnant stomach is a rare tumor but with poor prognosis. Compared with conventional open surgery, laparoscopic gastrectomy has potential benefits for these patients due to advantages resulting from its minimally invasive approach. Herein, we report on three patients with gastric cancer in remnant stomach who underwent laparoscopic total gastrectomy with intracorporeal esophagojejunostomy successfully. The operative time was 280, 250 and 225 minutes, the estimated blood loss was 100, 80 and 50 ml and the length of postoperative hospital stay was seven, eight and nine days respectively. Our experience has suggested that laparoscopic total gastrectomy with intracorporeal esophagojejunostomy can be a safe, feasible and promising option for patients with gastric cancer in remnant stomach.

Full Text Available Little is known about the long term occurrence and prevalence of upper abdominal complaints after previous partial gastrectomy. Therefore, a retrospective, uncontrolled, cross-sectional, descriptive, clinical, endoscopic study was done. A questionnaire was mailed to patients who had undergone partial gastrectomy and been sent for upper gastrointestinal endoscopy. Eight questions were scored on a five-point Likert scale, and a symptom score was calculated. During the five-year study period, 189 patients (137 men, 52 women were identified as having had a partial gastrectomy -- 143 (76% received the Billroth II operation and 46 (24% received the Billroth I operation. The questionnaire was mailed to 124 patients, of whom 79 (64% responded. Eighty-eight per cent of patients had undergone surgery more than 15 years earlier. Fifty-nine patients (75% suffered from upper abdominal symptoms. Regurgitation of food, retrosternal heartburn and bile reflux occurred significantly more often in patients who underwent the Billroth II operation. The mean symptom score of patients who underwent Billroth I resection was significantly lower (4.5 [SD 3.6] than that of patients who underwent Billroth II resection (7.1 [SD 4.4](P=0.04. One or more symptoms indicative of dumping were found in 70% of patients who underwent Billroth II resection and in 59% of patients who underwent Billroth I resection (not significant. Many patients who had undergone a partial gastrectomy developed upper abdominal symptoms during long term follow-up that were not specifically linked to dumping.

To evaluate the short-term outcomes and quality of life (QoL) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-later-cut overlap method (IJOM) after totally laparoscopic total gastrectomy (TLTG). A total of 507 patients who underwent laparoscopic gastrectomy (D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG (group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy (LATG) (group A, n = 456). The short-term outcomes and QoL were compared between the two groups after 1:2 propensity-score matching (PSM). We used a questionnaire to assess QoL. Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups ( P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A ( P < 0.05). After matching, group T reported better QoL in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better QoL ("Have you felt pain" and "Have you had difficulty eating solid food") ( P < 0.05). The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving QoL after laparoscopic gastrectomy.

Full Text Available Context Whether adjuvant chemoradiotherapy may contribute to improve survival outcomes after D2-gastrectomy remains controvertial. Objective To explore the clinical utility of N-Ratio in selecting gastric cancer patients for adjuvant chemoradiotherapy after D2-gastrectomy. Methods A retrospective cohort study was carried out on gastric cancer patients who underwent D2-gastrectomy alone or D2-gastrectomy plus adjuvant chemoradiotherapy (INT-0116 protocol at the Hospital A. C. Camargo from September 1998 to December 2008. Statistical analysis were performed using multiple conventional methods, such as c-statistic, adjusted Cox's regression and stratified survival analysis. Results Our analysis involved 128 patients. According to c-statistic, the N-Ratio (i.e., as a continuous variable presented “area under ROC curve” (AUC of 0.713, while the number of metastatic nodes presented AUC of 0.705. After categorization, the cut-offs provide by Marchet et al. displayed the highest discriminating power – AUC value of 0.702. This N-Ratio categorization was confirmed as an independent predictor of survival using multivariate analyses. There also was a trend of better survival by adding of adjuvant chemoradiotherapy only for patients with milder degrees of lymphatic spread – 5-year survival of 23.1% vs 66.9%, respectively (HR = 0.426, 95% CI 0.150–1.202; P = 0.092. Conclusions This study confirms the N-Ratio as a tool to improve the lymph node metastasis staging in gastric cancer and suggests the cut-offs provided by Marchet et al. as the best way for its categorization after a D2-gastrectomy. In these settings, the N-Ratio appears a useful tool to select patients for adjuvant chemoradiotherapy, and the benefit of adding this type of adjuvancy to D2-gastrectomy is suggested to be limited to patients with milder degrees of lymphatic spread (i.e., NR2, 10%–25%.

The aim of the study was to determine one-year effects of total gastrectomy on plasma silicon and free amino acid concentrations in patients and evaluate changes of volumetric bone mineral density (vBMD) in lumbar spine. Eight patients were enrolled to the control (CTR) group. Six patients subjected to total gastrectomy (GX group) were included to the experimental group. vBMD in trabecular and cortical bone was measured in lumbar vertebrae at baseline (before surgery) and one year later using quantitative computed tomography. Plasma concentrations of silicon and free amino acids were determined at baseline and one year later using photometric method and ion-exchange chromatography. Body weights within CTR and GX groups were not different after one-year follow-up when compared to the baseline values (P > 0.05). An average annual decrease of vBMD in the trabecular bone in the gastrectomized patients reached 15.0% in lumbar spine and was significantly different in comparison to the percentage changes observed in CTR group (P = 0.02). One-year percentage change of vBMD in the cortical bone in L1 and L2 has shown significantly decreased values by 10.5 and 9.1% in the GX group when compared to the percentage change observed in the controls (P silicon was significantly lowered by 26.7% one year after the total gastrectomy when compared to the baseline value (P = 0.009). Total gastrectomy in patients has induced severe osteoporotic changes in lumbar spine within one-year period. The observed osteoporotic changes were associated with decreased plasma concentration of silicon indicating importance of exocrine and endocrine functions of stomach for silicon homeostasis maintenance. Gastrectomy-induced bone loss was not related to decreased amino acid concentration in plasma obtained from overnight fasted patients. © 2015 by the Society for Experimental Biology and Medicine.

Old age is regarded as the risk factor of major abdominal surgery due to the lack of functional reserve and the increased presence of comorbidities. This study aimed to evaluate the impact of old age on the surgical outcomes of totally laparoscopic gastrectomy for gastric cancer. This study enrolled 389 gastric cancer patients who underwent totally laparoscopic gastrectomy at Hanyang University Guri Hospital and ASAN Medical Center. The patients were classified into two groups according to age as those older than 70 years and those younger than 70 years. Early surgical outcomes such as operation time, postoperative complications, time to first flatus, days until soft diet began, and hospital stay were evaluated. No patient was converted to open surgery. The two groups differed significantly in terms of overall postoperative complication rate, time to first flatus, days until soft diet began, and hospital stay. The patients who underwent Roux-en-Y gastrojejunostomy differed in incidence of postoperative ileus but not in severe postoperative complication rate. The results of this study demonstrated that old age can have an effect on the surgical outcomes of totally laparoscopic gastrectomy. This study especially showed that elderly patients are affected by the return of bowel movement after totally laparoscopic gastrectomy. On the other hand, however, it is presumed that old age has not had a serious impact on surgical outcomes in totally laparoscopic gastrectomy because no difference in the severe postoperative complication rate was observed.

Nutritional assessment methods as predictors of postoperative mortality in gastric cancer patients submitted to gastrectomy

Directory of Open Access Journals (Sweden)

Aline Kirjner Poziomyck

Full Text Available ABSTRACT Objectives: to determine the nutritional evaluation method that best predicts mortality in 90 days of patients submitted to gastrectomy for gastric cancer. Methods: we conducted a prospective study with 44 patients with gastric cancer, stages II to IIIa, of whom nine were submitted to partial gastrectomy, 34 to total gastrectomy, and one to esophago-gastrectomy. All patients were nutritionally evaluated through the same protocol, up to 72h after hospital admission. The parameters used were Patient-Generated Subjective Global Assessment (PGSGA, classical anthropometry, current weight and height, percentage of weight loss (%WL and body mass index (BMI. We also measured the thickness of the thumb adductor muscle (TAM in both hands, dominant hand (TAMD and non-dominant hand (TAMND, as well as the calculated the prognostic nutritional index (PNI. The laboratory profile included serum levels of albumin, erythrocytes, hemoglobin, hematocrit, leukocytes, and total lymphocytes count (TLC. Results: of the 44 patients studied, 29 (66% were malnourished by the subjective method, 15 being grade A, 18 grade B and 11 grade C. Cases with PGSGA grade B and TAMD 10.2±2.9 mm were significantly associated with higher mortality. The ROC curves (95% confidence interval of both PGSGA and TAMD thickness reliably predicted mortality at 30 and 90 days. No laboratory method allowed predicting mortality at 90 days. Conclusion: PGSGA and the TAMD thickness can be used as preoperative parameters for risk of death in patients undergoing gastrectomy for gastric cancer.

Purpose: To evaluate the use of laparoscopy, CT, colonic enema (CE), and laboratory tests (white blood cell count (WBC), sedimentation rate (SR), and C-reactive protein (CRP)) in diagnosing diverticulitis of the sigmoid colon. Material and Methods: The diagnostic methods were prospectively evaluated in 88 patients, 30 of whom were referred for laparoscopy. Results: Fity-two patients were found to have sigmoid diverticulitis: 20 patients by lanparoscopy, 21 by CT, and 11 by CE combined with one positive laboratory test. Laparoscopy proved to be superior to the other diagnostic methods in diagnosing diverticulitis of the sigmoid colon. CT had a high specificity (1.0; 95% CI: 0.92-1.0) but low sensitivity (0.69; 95% CI: 0.56-0.79) in detecting diverticulitis. CE had a higher sensitivity (0.82; 95% CI: 0.71-0.90) but a lower specificity (0.81; 95% CI: 0.67-0.91) than CT. Conclusion: CT was the best method for diagnosing abdominal pathology outside the colon. CT can be recommended as the first examination in seriously ill patients where abscesses and other causes of the symptoms than diverticulitis must first be rule out. Laparoscopy is probably the most accurate method in diagnosing diverticulitis. (orig.)

DISTAL MYOPATHIES

Over a century ago, Gowers described two young patients in whom distal muscles weakness involved the hand, foot, sternocleidomastoid, and facial muscles in the other case the shoulder and distal leg musculature. Soon after, , similar distal myopathy cases were reported whereby the absence of sensory symptoms and of pathologic changes in the peripheral nerves and spinal cord at postmortem examination allowed differentiation from Charcot-Marie-Tooth disease. In 1951, Welander described autosomal dominant (AD) distal arm myopathy in a large Scandanavian cohort. Since then the number of well-characterized distal myopathies has continued to grow such that the distal myopathies have formed a clinically and genetically heterogeneous group of disorders. Affected kindred commonly manifest weakness that is limited to foot and toe muscles even in advanced stages of the disease, with variable mild proximal leg, distal arm, neck and laryngeal muscle involvement in selected individuals. An interesting consequence of the molecular characterization of the distal myopathies has been the recognition that mutation in a single gene can lead to more than one clinical disorder. For example, Myoshi myopathy (MM) and limb girdle muscular dystrophy (LGMD) type 2B are allelic disorders due to defects in the gene that encodes dysferlin. The six well described distal myopathy syndromes are shown in Table 1. Table 2 lists advances in our understanding of the myofibrillar myopathy group and Table 3 includes more recently delineated and less common distal myopathies. In the same manner, the first section of this review pertains to the more traditional six distal myopathies followed by discussion of the myofibrillar myopathies. In the third section, we review other clinically and genetically distinctive distal myopathy syndromes usually based upon single or smaller family cohorts. The fourth section considers other neuromuscular disorders that are important to recognize as they display prominent

The number of published series on minimally invasive distal pancreatectomy has significantly increased. Robotic systems can overcome some limitations of laparoscopy. This study aimed to compare two techniques in distal pancreatectomy. Multiple electronic databases were systematically searched to identify studies (up to July 2015) that compared perioperative outcomes between robotic distal pancreatectomy (RDP) and laparoscopic distal pancreatectomy (LDP). Relative risks with 95 % confidence intervals (CIs) were estimated. Nine studies were enrolled in this review. Four studies reported on operative time, indicating no difference between the RDP and LDP groups (WMD = 21.55, 95 % CI -65.28-108.37, P = 0.63). No significant difference between the two groups was indicated with respect to the number of patients who converted to open (OR 0.35, 95 % CI 0.11-1.13, P = 0.08), spleen preservation rate (OR 2.37, 95 % CI 0.50-11.30, P = 0.28), and transfusion rate (OR 1.30, 95 % CI 0.54-3.13, P = 0.56). In addition, no difference was indicated in the incidence of pancreatic fistulas (OR 1.05, 95 % CI 0.67-1.65, P = 0.83) and length of hospital stay between the two groups (WMD = -0.61, 95 % CI -1.40-0.19, P = 0.13). RDP seems to be a safe and effective alternative to LDP. Large randomized controlled trials are needed to verify the results of this meta-analysis.

Jeremy R Huddy

2013-01-01

Full Text Available Introduction: Experience has allowed increasingly complex procedures to be undertaken by single port surgery. We describe a technique for single port Billroth I gastrectomy with a hand-sewn intracorporeal anastomosis in the resection of a benign tumour diagnosed incidentally on a background of cholelithiasis. Materials and Methods: Single port Billroth I gastrectomy and cholecystectomy was performed using a transumbilical quadport. Flexible tipped camera and straight conventional instruments were used throughout the procedure. The stomach was mobilised including a limited lymph node dissection and resection margins in the proximal antrum and duodenum were divided with a flexible tipped laparoscopic stapler. The lesser curve was reconstructed and an intracorporal hand sewn two layer end-to-end anastomosis was performed using unidirectional barbed sutures. Intraoperative endoscopy confirmed the anastomosis to be patent without leak. Results: Enteral feed was started on the day of surgery, increasing to a full diet by day 6. Analgesic requirements were a patient-controlled analgesia morphine pump for 4 postoperative days and paracetamol for 6 days. There were no postoperative complications and the patient was discharged on the eighth day. Histology confirmed gastric submucosal lipoma. Discussion: As technology improves more complex procedures are possible by single port laparoscopic surgery. In this case, flexible tipped cameras and unidirectional barbed sutures have facilitated an intracorporal hand-sewn two layer end-to-end anastomosis. Experience will allow such techniques to become mainstream.

In 63 patients after total gastrectomy and reconstruction of the small bowel described by Beal-Longmire, Roux and Tomoda radiological findings were correlated with clinical symptoms. No correlation could be found between clinical symptoms of dumping and oesophagitis caused by reflux on one side and increased length of intestinal transit time, increased diameter of intestinal loops and gastro-oesophageal reflux on the other side. Enlarged blind loops after termino-lateral oesophago-jejunostomy and insufficient ligations (operation technique by Tomoda) were correlated with higher incidence of pains. Patients operated by the method of Beal-Longmire and Roux showed better results than those operated with the method of Tomoda.

Full Text Available Introduction. The placement of ring or band around the gastric tube might prevent the dilation after Laparoscopic Sleeve Gastrectomy (LSG. We describe the first randomized study comparing LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG. Material and Method. Fifty obese patients were enrolled in the study between January 2014 and January 2015. We analysed differences in operative time, complication rate, mortality, and BMI between the two groups over a period of 12 months. Results. Twenty-five patients received LSG (group A and 25 LBSG (group B. The mean preoperative BMI was 47.3±6.58 kg/m2 and 44.95±5.85 kg/m2, respectively, in the two groups. There was no statistical relevant difference in operative time. No intraoperative complications occurred. Mean BMI registered after 3, 6, and 12 months in groups A and B, respectively, were 37.86±5.72 kg/m2 and 37.58±6.21 kg/m2 (p=0.869, 33.64±6.08 kg/m2 and 32.03±5.24 kg/m2 (p=0.325, and 29.72±4.40 kg/m2 and 27.42±4.47 kg/m2 (p=0.186; no statistical relevant difference was registered between the two groups. Conclusion. LBSG is a safe and feasible procedure. The time required for the device positioning did not influence significantly the surgical time. The results of bodyweight loss did not document any statistically significant differences among the two groups, even though LBSG group showed a mean BMI slightly lower than that of the control group.

The aim of the present study is to evaluate mental workload and fatigue in fingers, hand, arm, shoulder in single-incision laparoscopic surgery (SILS) and multiport laparoscopy. Volunteers performed chosen tasks by standard laparoscopy and SILS. Time to complete tasks and finger and hand strength were evaluated. Lateral, tripod, and pulp pinch strengths were measured. Hand dexterity was determined by pegboard. Electromyography recordings were taken from biceps and deltoid muscles of both extremities. The main outcome measurement was median frequency (MF) slope. NASA-TLX was used for mental workload. Time to complete laparoscopic tasks were longer in the SILS group (P NASA-TLX score was 73 ± 13.3 and 42 ± 19.5 in SILS and multiport laparoscopy, respectively (P < .01). Mental demand, physical demand, temporal demand, performance, effort, and frustration were, respectively, scored 10.7 ± 3.8, 11.7 ± 3.5, 12.2 ± 2.7, 11 ± 3, 13.6 ± 2.7, and 13.5 ± 2.8 in SILS and 6.3 ± 3.1, 6.6 ± 3.3, 7.3 ± 3.3, 7.1 ± 4.1, 7.9 ± 3.9, and 6.6 ± 3.8 in standard laparoscopy (P < .01). SILS is mentally and physically demanding, particularly on arms and shoulders. Fatigue of big muscles, effort, and frustration were major challenges of SILS. Ergonomic intervention of instruments are needed to decrease mental and physical workload. © The Author(s) 2014.

Olfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. A laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit. Analyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all). Here, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.

Artificial tactile sensing is a novel method for obtaining different characteristics of a hard object embedded in a soft tissue. In this regard, artificial palpation is one of the most valuable achievements of artificial tactile sensing that can be used in various fields of medicine and more specifically in surgery. In this study, considering the present problems and limitations in kidney-stone-removal laparoscopy, a new application will be presented for artificial tactile sensing approach. Having imitated surgeon's palpation during open surgery and modeled it conceptually, indications of stone existence that appear on the surface of kidney (due to exerting mechanical load) were determined. A number of different cases were created and solved by the software. Using stress distribution contours and stress graphs, it is illustrated that the created stress patterns on the surface of kidney not only show the existence of stone inside, but also its exact location. In fact, the reliability and accuracy of artificial tactile sensing method in detection of kidney stone during laparoscopy is demonstrated by means of finite element analysis. Also, in this paper, the functional principles of tactile system capable of determining the exact location of stone during laparoscopy will be presented.

Full Text Available Ovarian cysts are the most common cause of pelvic masses in women. Although laparoscopic surgery is considered the gold standard treatment for ovarian cysts, most of the large ovarian cysts continue to be treated by laparotomy due to technical difficulties. Laparoscopic-assisted cystectomy is an alternative operation type for managing such cases. A case of large ovarian cyst with adnexal torsion in a 21-year-old virgin patient is presented in this report. In this case laparoscopic-assisted cystectomy was performed without intraoperatif complication. Postoperative course was uneventful. Pathology revealed a benign serous cystadenoma. At 6 months follow up, she continued to be asymptomatic, and sonography showed no recurrence of her disease. Laparoscopic-assisted cystectomy is a safe and effective procedure for large adnexal cysts.

Analysis of perioperative outcomes and survival of patients with recurrent ovarian cancer undergoing secondary cytoreduction by robotics, laparoscopy, or laparotomy. Retrospective analysis of 52 selected patients with recurrent ovarian cancer undergoing secondary cytoreduction by laparoscopy (9), laparotomy (33) or robotics (10) between January 2006 and December 2010. Comparison was made by a total of 21 factors including age, BMI, number of previous surgeries, tumor type and grade, number of procedures, and 15 types of procedures performed at secondary cytoreduction. For all patients, the mean operating time was 213.8 min, mean blood loss 657.4 ml; and mean hospital stay 7.5 days. Complete debulking was achieved in 75% of patients. Postoperative complications were noted in 36.5% of patients. Overall and progression-free survival at 3-years were 58.8% and 34.1%, respectively. Laparoscopy and robotics had reduced blood loss and hospital stay, while no differences were observed among the three groups for operating time, complications, complete debulking, and survival. Selected patients with recurrent ovarian cancer benefit from a laparoscopic or robotic secondary cytoreduction without compromising survival. Robotics and laparoscopy provide similar perioperative outcomes, and reduced blood loss and shorter hospital stay as compared to laparotomy. Laparotomy seems preferable for patients with widespread peritoneal implants, multiple sites of recurrence, and/or extensive adhesions. Copyright © 2013 Elsevier Inc. All rights reserved.

Directory of Open Access Journals (Sweden)

Can Konca

2018-05-01

Full Text Available Background: Staple-line leak is the most frightening complication of laparoscopic sleeve gastrectomy and several predisposing factors such as using improper staple sizes regardless of gastric wall thickness, narrower bougie diameter and ischemia of the staple line are asserted. Aims: To evaluate the effects of different bougie diameters on tissue oxygen partial pressure at the esophagogastric junction after sleeve gastrectomy. Study Design: A randomized and controlled animal experiment with 1:1:1:1 allocation ratio. Methods: Thirty-two male Wistar Albino rats were randomly divided into 4 groups of 8 each. While 12-Fr bougies were used in groups 1 and 3, 8-Fr bougies were used in groups 2 and 4. Fibrin sealant application was also carried out around the gastrectomy line after sleeve gastrectomy in groups 3 and 4. Burst pressure of gastrectomy line, tissue oxygen partial pressure and hydroxyproline levels at the esophagogastric junction were measured and compared among groups. Results: Mortality was detected in 2 out of 32 rats (6.25% and one of them was in group 2 and the cause of this mortality was gastric leak. Gastric leak was detected in 2 out of 32 rats (6.25%. There was no significant difference in terms of burst pressures, tissue oxygen partial pressure and tissue hydroxyproline levels among the 4 groups. Conclusion: The use of narrower bougie along with fibrin sealant has not had a negative effect on tissue perfusion and wound healing.

Esophageal reflux symptom has been reported as common in patients with subtotal gastrectomy. Management of postoperative esophageal reflux symptom is not satisfactory. The aim of this study is to investigate prevalence of esophageal reflux symptom after subtotal gastrectomy and assess factors affecting esophageal reflux symptom in subtotal gastrectomy patients. We prospectively enrolled 100 consecutive patients with subtotal gastrectomy who were regularly followed up by endoscopic examination. Acid secretory capacity was assessed by measuring messenger RNA (mRNA) expression of H + /K + -adenosine triphosphatase (ATPase) via real-time polymerase chain reaction (PCR) in biopsy specimens. In total, 47 % of patients had typical esophageal reflux symptom, where heartburn or regurgitation was experienced at least weekly. Age, sex, body mass index, and type of reconstruction did not differ between esophageal reflux and non-esophageal-reflux groups. The esophageal reflux group had longer duration from time of operation until study (median 5.0 versus 3.6 years; P = 0.017). Hill grade for gastroesophageal (GE) flap valve was higher in the esophageal reflux group than in the non-esophageal-reflux group (P = 0.027). H + /K + -ATPase mRNA expression was higher in the esophageal reflux group than in the non-esophageal-reflux group [3967.6 (± 7583.7) versus 896.2 (± 1456.0); P = 0.006]. Multivariate analysis revealed that postoperative duration, H + /K + -ATPase mRNA expression level, and GE flap valve disruption were significantly associated with esophageal reflux symptom development. Esophageal reflux symptom is common in patients after subtotal gastrectomy, possibly because of anti-reflux-barrier impairment and preservation of acid secretory capacity following surgery. Optimal acid suppression may be helpful in managing postoperative esophageal reflux symptom.

BACKGROUND & AIMS Observational studies and small randomized controlled trials have shown that the use of laparoscopy in colon resection for diverticular disease is feasible and results in fewer complications. We analyzed data from a large, prospectively maintained, multicenter database (National Surgical Quality Initiative Program) to determine whether the use of laparoscopy in the elective treatment of diverticular disease decreases rates of complications compared with open surgery, independent of preoperative comorbid factors. METHODS The analysis included data from 6970 patients who underwent elective surgeries for diverticular disease from 2005 to 2008. Patients with diverticular disease were identified by International Classification of Diseases, 9th revision codes and then categorized into open or laparoscopic groups based on Current Procedural Terminology codes. Preoperative, intraoperative, and postoperative data were analyzed to determine factors associated with increased risk for postoperative complications. RESULTS Data were analyzed from 3468 patients who underwent open surgery and 3502 patients who underwent laparoscopic procedures. After correcting for probability of morbidity, American Society of Anesthesiology class, and ostomy creation, overall complications (including superficial surgical site infections, deep incisional surgical site infections, sepsis, and septic shock) occurred with significantly lower incidence among patients who underwent laparoscopic procedures compared with those who received open operations. CONCLUSIONS The use of laparoscopy for treating diverticular disease, in the absence of absolute contraindications, results in fewer postoperative complications compared with open surgery.

Keller, R; Kleemann, M; Hildebrand, P; Roblick, U J; Bruch, H-P

2006-11-01

Acute abdomen is not a disease in itself but a description of a complex of symptoms combined with severe abdominal pain developed within a time frame of less than 24 h. All strategies for the management of acute abdomen underline the need for an interdisciplinary approach to diagnosis and therapy. This requires focused and intelligent use of efficient diagnostic procedures. Diagnostic laparoscopy may be a key to solving the diagnostic dilemma of unspecific acute abdomen. Furthermore, it allows not only direct inspection of the abdominal cavity but also surgical intervention, if needed. In particular the rate of negative laparotomies can be reduced.

Postoperative complications are associated with increased hospital costs following major surgery, but the mechanism by which they increase cost and the categories of care that drive this increase are poorly described. To describe the association of postoperative complications with hospital costs following total gastrectomy for gastric adenocarcinoma. This retrospective analysis of a prospectively collected gastric cancer surgery database at a single National Cancer Institute-designated comprehensive cancer center included all patients undergoing curative-intent total gastrectomy for gastric adenocarcinoma between January 2009 and December 2012 and was conducted in 2015 and 2016. Ninety-day normalized postoperative costs. Hospital accounting system costs were normalized to reflect Medicare reimbursement levels using the ratio of hospital costs to Medicare reimbursement and categorized into major cost categories. Differences between costs in Medicare proportional dollars (MP $) can be interpreted as the amount that would be reimbursed to an average hospital by Medicare if it paid differentially based on types and extent of postoperative complications. In total, 120 patients underwent curative-intent total gastrectomy for stage I through III gastric adenocarcinoma between 2009 and 2012. Of these, 79 patients (65.8%) were men, and the median (interquartile range) age was 64 (52-70) years. The 51 patients (42.5%) who underwent an uncomplicated total gastrectomy had a mean (SD) normalized cost of MP $12 330 (MP $2500), predominantly owing to the cost of surgical care (mean [SD] cost, MP $6830 [MP $1600]). The 34 patients (28.3%) who had a major complication had a mean (SD) normalized cost of MP $37 700 (MP $28 090). Surgical care was more expensive in these patients (mean [SD] cost, MP $8970 [MP $2750]) but was a smaller contributor to total cost (24%) owing to increased costs from room and board (mean [SD] cost, MP $11 940 [MP $8820]), consultations (mean [SD

Extended Distal Pancreatectomy with En Bloc Resection of the Celiac Axis for Locally Advanced Pancreatic Cancer: A Case Report and Review of the Literature

2012-01-01

Full Text Available Due to a lack of early symptoms, pancreatic cancers of the body and tail are discovered mostly at advanced stages. These locally advanced cancers often involve the celiac axis or the common hepatic artery and are therefore declared unresectable. The extended distal pancreatectomy with en bloc resection of the celiac artery may offer a chance of complete resection. We present the case of a 48-year-old female with pancreatic body cancer invading the celiac axis. The patient underwent laparoscopy to exclude hepatic and peritoneal metastasis. Subsequently, a selective embolization of the common hepatic artery was performed to enlarge arterial flow to the hepatobiliary system and the stomach via the pancreatoduodenal arcades from the superior mesenteric artery. Fifteen days after embolization, the extended distal pancreatectomy with splenectomy and en bloc resection of the celiac axis was carried out. The postoperative course was uneventful, and complete tumor resection was achieved. This case report and a review of the literature show the feasibility and safety of the extended distal pancreatectomy with en bloc resection of the celiac axis. A preoperative embolization of the celiac axis may avoid ischemia-related complications of the stomach or the liver.

Full Text Available INTRODUCTION: Dysphagia is the important symptom in achalasia, and surgery is the most common treatment. The Heller-Pinotti technique is the method preferred by Brazilian surgeons. For many years, this technique was performed by laparotomy, and now the laparoscopic method has been introduced. The objective was to evaluate the immediate and long-term results of patients submitted to surgery by either laparotomy or laparoscopy. MATERIALS AND METHODS: A total of 67 patients submitted to surgery between 1994 and 2001 with at least 5 years of follow-up were evaluated retrospectively and divided into two groups: laparotomy (41 patients and laparoscopy (26 patients. Chagas was the etiology in 76.12% of cases. Dysphagia was evaluated according to the classification defined by Saeed et al. RESULTS: There were no cases of conversion to open surgery. The mean duration of hospitalization was 3.32 days for laparotomy and 2.54 days for laparoscopy (p<0.05. An improvement in dysphagia occurred with both groups reporting good or excellent results (laparotomy: 73.17% and laparoscopy: 73.08%. Mean duration of follow-up was 8 years. CONCLUSIONS: There was no difference between the two groups with respect to relief from dysphagia, thereby confirming the safety and effectiveness of the Heller-Pinotti technique, which can be performed by laparotomy or laparoscopy, depending on the surgeon's experience.

Objective: To evaluate the diagnostic efficacy of laparoscopy in ill-defined recurrent chronic abdominal pain. Study Design: Prospective study. Place and Duration of Study: Surgical department, Military Hospital Rawalpindi, from Jul 2011 to Dec 2013. Material and Methods: A total of 102 patients who presented to surgical department with chronic recurrent abdominal pain of unknown etiology and underwent diagnostic laparoscopy were included in our study. Patients with acute onset of abdominal pain, hemodynamically unstable, pregnant or those in which diagnosis can be made by radiological techniques were excluded from our study. Patient's demographic data, clinical findings and laparoscopic findings were recorded. Finally data was analyzed by using SPSS version 21. Results: Out of 110 patients 96 were female while remaining 14 were male. The age range of the patients was 20- 70 years with mean age of 50 +- 10 years. The most common site of pain was lower abdomen while mean duration of abdominal pain was 34 weeks. Laparoscopic findings include acute recurrent appendicitis in 32 (29.09%) patients, cholecystitis with biliary sludge in 14 (12.72%), pelvic inflammatory disease in 12 (10.90%), ovarian cyst in 11(10%), adhesions in 10(9.09%), intestinal tuberculosis in 8 (7.27%), mesenteric lymphadenitis in 7 (6.36%), lymphoma in 4 (3.63%), ectopic pregnancy in 3 (2.7%), CA gallbladder in 2 (1.81%), meckels diverticulum in 2 (1.81%), endometriosis in 2 (1.81%) and crohns disease in 1 (0.9%) patients. Mean operative time was 48 min while average hospital stay was 2-3 days. No major complications were noticed. Conclusion: Laparoscopy in our clinical setup has significant role in diagnosing cases of vague abdominal pain which cannot be diagnosed by routine investigations. (author)

The Society of Gynecologic Surgeons Systematic Review Group performed a systematic review of both randomized and observational studies to compare robotic vs nonrobotic surgical approaches (laparoscopic, abdominal, and vaginal) for treatment of both benign and malignant gynecologic indications to compare surgical and patient-centered outcomes, costs, and adverse events associated with the various surgical approaches. MEDLINE and the Cochrane Central Register of Controlled Trials were searched from inception to May 15, 2012, for English-language studies with terms related to robotic surgery and gynecology. Studies of any design that included at least 30 women who had undergone robotic-assisted laparoscopic gynecologic surgery were included for review. The literature yielded 1213 citations, of which 97 full-text articles were reviewed. Forty-four studies (30 comparative and 14 noncomparative) met eligibility criteria. Study data were extracted into structured electronic forms and reconciled by a second, independent reviewer. Our analysis revealed that, compared with open surgery, robotic surgery consistently confers shorter hospital stay. The proficiency plateau seems to be lower for robotic surgery than for conventional laparoscopy. Of the various gynecologic applications, there seems to be evidence that renders robotic techniques advantageous over traditional open surgery for management of endometrial cancer. However, insofar as superiority, conflicting data are obtained when comparing robotics vs laparoscopic techniques. Therefore, the specific method of minimally invasive surgery, whether conventional laparoscopy or robotic surgery, should be tailored to patient selection, surgeon ability, and equipment availability.

2010-12-01

Full Text Available Aim: The aim of this study was to evaluate the reconstruction methods applied after total gastrectomy in terms of postoperative symptomology and nutrition. Methods: This retrospective study was conducted on 31 patients who underwent total gastrectomy due to gastric cancer in 2. Clinic of General Surgery, SSK Ankara Training Hospital. 6 different reconstruction methods were used and analyzed in terms of age, sex and postoperative complications. One from esophagus and two biopsy specimens from jejunum were taken through upper gastrointestinal endoscopy from all cases, and late period morphological and microbiological changes were examined. Postoperative weight change, dumping symptoms, reflux esophagitis, solid/liquid dysphagia, early satiety, postprandial pain, diarrhea and anorexia were assessed. Results: Of 31 patients,18 were males and 13 females; the youngest one was 33 years old, while the oldest- 69 years old. It was found that reconstruction without pouch was performed in 22 cases and with pouch in 9 cases. Early satiety, postprandial pain, dumping symptoms, diarrhea and anemia were found most commonly in cases with reconstruction without pouch. The rate of bacterial colonization of the jejunal mucosa was identical in both groups. Reflux esophagitis was most commonly seen in omega esophagojejunostomy (EJ, while the least-in Roux-en-Y, Tooley and Tanner 19 EJ. Conclusion: Reconstruction with pouch performed after total gastrectomy is still a preferable method. (The Medical Bulletin of Haseki 2010; 48:126-31

This study aims to analyze the scientific production about patients with gastric cancer submitted to gastrectomy and describe important aspects of nursing guidelines for these patients. An integrative review was carried out using Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE) databases; twenty two articles were analyzed. Retrospective cross-sectional studies were the most frequent. The scientific production of nursing is numerically small in relation to the medical area. The results show that approaches related to pre and post-operative in gastrectomy for gastric cancer resection subsidize the knowledge of issues essential for nurses to promote efficient intervention for the recovery of such patients. There is still the need for further research on the practice of nursing in the guidelines of this kind of surgery.

Laparoscopy has been used for the diagnosis and treatment for hemodynamically stable patients with penetrating abdominal trauma. This study evaluated whether diagnostic and therapeutic laparoscopy can be used as effectively in select patients with blunt abdominal trauma. All hemodynamically stable patients undergoing operations for blunt abdominal trauma over a 10-year period (2006-2015) at a tertiary medical center were included. Patients undergoing laparotomy were categorized as group A. Patients who underwent laparoscopy were categorized as group B. The clinical outcomes of the 2 groups were compared. There were 139 patients in group A and 126 patients in group B. Group A patients were more severely injured (mean injury severity score of 23.3 vs. 18.9, P .05). Laparoscopy is a feasible and safe tool for the diagnosis and treatment of hemodynamically stable patients with blunt abdominal trauma who require surgery.

Bariatric procedures are technically complex and skill demanding. In order to standardize the procedures for research and training, a Delphi analysis was performed to reach consensus on the practice of the laparoscopic gastric bypass and sleeve gastrectomy in the Netherlands. After a pre-round identifying all possible steps from literature and expert opinion within our study group, questionnaires were send to 68 registered Dutch bariatric surgeons, with 73 steps for bypass surgery and 51 steps for sleeve gastrectomy. Statistical analysis was performed to identify steps with and without consensus. This process was repeated to reach consensus of all necessary steps. Thirty-eight participants (56%) responded in the first round and 32 participants (47%) in the second round. After the first Delphi round, 19 steps for gastric bypass (26%) and 14 for sleeve gastrectomy (27%) gained full consensus. After the second round, an additional amount of 10 and 12 sub-steps was confirmed as key steps, respectively. Thirteen steps in the gastric bypass and seven in the gastric sleeve were deemed advisable. Our expert panel showed a high level of consensus expressed in a Cronbach's alpha of 0.82 for the gastric bypass and 0.87 for the sleeve gastrectomy. The Delphi consensus defined 29 steps for gastric bypass and 26 for sleeve gastrectomy as being crucial for correct performance of these procedures to the standards of our expert panel. These results offer a clear framework for the technical execution of these procedures.

Gastrectomy remains the primary therapeutic method for resectable gastric cancer. Thought of as an important measure to reduce post-operative complications and mortality, abdominal drainage has been used widely after gastrectomy for gastric cancer in previous decades. The benefits of abdominal drainage have been questioned by researchers in recent years. The objectives of this review were to assess the benefits and harms of routine abdominal drainage post-gastrectomy for gastric cancer. We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases (UGPD) Group Specialised Register and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2014, Issue 11); MEDLINE (via PubMed) (1950 to November 2014); EMBASE (1980 to November 2014); and the Chinese National Knowledge Infrastructure (CNKI) Database (1979 to November 2014). We included randomised controlled trials (RCTs) comparing an abdominal drain versus no drain in patients who had undergone gastrectomy (not considering the scale of gastrectomy and the extent of lymphadenectomy); irrespective of language, publication status, and the type of drain. We excluded RCTs comparing one drain with another. We adhered to the standard methodological procedures of The Cochrane Collaboration. From each included trial, we extracted the data on the methodological quality and characteristics of the participants, mortality (30-day mortality), re-operations, post-operative complications (pneumonia, wound infection, intra-abdominal abscess, anastomotic leak, drain-related complications), operation time, length of post-operative hospital stay, and initiation of a soft diet. For dichotomous data, we calculated the risk ratio (RR) and 95% confidence interval (CI). For continuous data, we calculated mean difference (MD) and 95% CI. We tested heterogeneity using the Chi(2) test. We used a fixed-effect model for data analysis with RevMan software, but we used a random-effects model if the P value of

The incidence of abdominal tuberculosis is much higher in an HIV-positive cohort. The use of laparoscopy in the diagnostic work-up of suspected abdominal tuberculosis is underutilized and its use and efficacy in the context of HIV co-infection has never been examined. A prospective clinical audit of the use of diagnostic laparoscopy was conducted in patients with clinically suspected abdominal tuberculosis but histologically or microbiologically unconfirmed tuberculosis at any site. From January 2008 to June 2010, 81 patients underwent diagnostic laparoscopy; 34 were male and 47 were female, with a mean age of 33 years, and 77 % were HIV-positive. Fifty-five patients (68 %) had positive histology or culture for tuberculosis. In 15 patients (19 %), histology revealed non-specific inflammation, no pathology was found in one patient, and no specimen was taken from one patient. Eighty percent of peritoneal deposits and 77 % of lymph nodes were positive for tuberculosis, whereas 35 % of ascitic fluid cultures were positive. In nine patients (11 %) an alternative diagnosis was found; nine patients (11 %) had conversion to laparotomy. There was no procedure-related death. Nine patients (11 %) died during the 2-month follow-up period. Diagnostic laparoscopy avoids the morbidity and mortality of laparotomy in chronically ill patients, and reduces the rate of misdiagnosis of other abdominal conditions and unnecessary long-term therapy. Diagnostic laparoscopy and tissue sampling is a viable and reliable strategy in patients with suspected abdominal tuberculosis.

An experience with laparoscopic sleeve gastrectomy using the natural orifice specimen extraction (NOSE) technique. Bariatric surgery is nowadays the only long term effective obesity treatment method. Twenty one consecutive patients underwent laparoscopic sleeve gastrectomy with the use of natural orifice specimen extraction (NOSE) in the Surgical Clinic of Faculty Hospital Ostrava between May 2012 and August 2012. Inclusion criteria were the body mass index (BMI) higher than 35 kg/m2 or higher than 32 kg/m2 accompanied with relevant comorbidities. Among 21 patients in this series, there were three men (14.3%) and 18 women (85.7%). Their mean age was 40.9±10.2 years. Their mean preoperative BMI was 40.4±4.6 kg/m2. No patient had previous bariatric surgery, one patient had laparoscopic fundoplication. All operations were completed laparoscopically with no conversions to an open procedure. In two cases, laparoscopic cholecystectomy was performed and the gallbladder was extracted along with the gastric specimen by transgastric approach. Laparoscopic sleeve gastrectomy is a safe and effective bariatric procedure with low morbidity and mortality. Based on our initial experiences it could be an indication for NOSE with transgastric approach. Obese patients would benefit from this approach due to the elimination of wound complications (Tab. 2, Fig. 3, Ref. 22).

Laparoscopy is increasingly utilised as a diagnostic tool in management of abdominal trauma; however its role in therapeutic intervention remains unexplored. The aim of this study is to compare laparoscopy with laparotomy in the treatment of abdominal trauma in haemodynamically stable patients. A review of patients undergoing surgery for abdominal trauma between January 2004-2014 identified 25 patients who underwent laparoscopy for therapeutic intervention (TL). This group was matched with 25 similar patients undergoing laparotomy (LT). Matching of the two cohorts was based on patient characteristics, severity of injuries, haemodynamic compromise and radiological findings. Peri-operative outcomes were compared. Patient characteristics were similar in TL and LT patients for age (median 33 vs. 26 years), gender distribution and clinical presentation. Injury severity score was also similar with a median of 16 in both groups (major trauma = ISS>15, normal range 0-75). Types of injuries included; hollow viscus [bowel repair = 10 (TL) vs. 16 (LT)] and solid organs [5(TL) vs. 2 (LT)]. Median operating time was similar in both groups; 105(TL) compared to 98 (LT) minutes. Post-operative complications (1 vs. 10, p = 0.02), analgesia requirements, specifically opiate use (34 vs. 136 morphine equivalents, p = 0.002) and hospital stay (4 vs. 9 days, p = 0.03) were significantly lower in the laparoscopy group. Abdominal trauma in haemodynamically stable patients can be managed effectively and safely with laparoscopy by experienced surgeons. Major benefits may include lower morbidity, reduced pain, and shorter length of hospital stay. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Educational system of laparoscopic gastrectomy for trainee-how to teach, how to learn.

Science.gov (United States)

Kaito, Akio; Kinoshita, Takahiro

2017-01-01

The feasibility of laparoscopic gastrectomy (LG) has been gradually proven by several scientific works, however, proper training method for this kind of surgery are still under investigation and debate. Here we report our educational system of LG to enhance the skill of young surgeons in our hospital. Our training program for trainee consists of 3 years of junior residency and 2 years of senior residency programs, requiring 5 years in total. In order to master LG, three following factors seem to be essential: learning, practice and experience. Learning means that trainee study techniques and concepts by educational materials, such as operative videos, lectures, or textbook. Practice means animal laboratory training or dry box training to acquire hand-eye coordination or bi-hand coordination, leading to precise movement of surgical devices. Experience means actual on-site training, participating in clinical LG as scopist, assistant or operator. In the actual surgery, we have some common principles for scopist, assistant and operator, respectively, and these principles are shared by entire surgical team. These principles are transmitted from trainer to trainee using simple keywords repeatedly. In conclusion, combination and balance of the three factors, learning, practice and experience are necessary to efficiently advance education of LG for trainee and may leads to benefits for gastric cancer patients.

Chronic pelvic pain: how does noninvasive imaging compare with diagnostic laparoscopy?

Science.gov (United States)

Tirlapur, Seema A; Daniels, Jane P; Khan, Khalid S

2015-12-01

Chronic pelvic pain (CPP) has an annual prevalence of 38/1000 in the UK, with coexisting pathologies often present. Diagnostic laparoscopy has long been the gold standard diagnostic test, but with up to 40% showing no abnormality, we explore the value of noninvasive imaging, such as pelvic ultrasound and MRI. A literature review from inception until January 2015 of the following databases: PubMed, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica database, and System for Information on Grey Literature in Europe were performed to identify published studies assessing the usefulness of ultrasound, MRI, and laparoscopy in the diagnosis of CPP. Three studies (194 women) addressed their comparative performance in patients with endometriosis, showing the sensitivity of ultrasound ranged between 58 and 88.5%; MRI was 56-91.5% and in the one study using histology as its reference standard, the sensitivity of laparoscopy was 85.7%. Noninvasive imaging has the additional benefit of being well tolerated, safer, and cheaper than surgery. CPP, by nature of its multifactorial causation, can be difficult to manage and often requires a multidisciplinary team. Ultrasound and MRI may provide information about the presence or lack of abnormality, which would allow general practitioners or office gynaecologists to initiate treatment and think about surgery as a second-line investigative tool.

Surgical complications are a major disincentive to pancreas transplantation, despite the undisputed benefits of restored insulin independence. The da Vinci surgical system, a computer-assisted electromechanical device, provides the unique opportunity to test whether laparoscopy can reduce the morbidity of pancreas transplantation. Pancreas transplantation was performed by robot-assisted laparoscopy in three patients. The first patient received a pancreas after kidney transplant, the second a simultaneous pancreas kidney transplantation, and the third a pancreas transplant alone. Operations were carried out through an 11-mm optic port, two 8-mm operative ports, and a 7-cm midline incision. The latter was used to introduce the grafts, enable vascular cross-clamping, and create exocrine drainage into the jejunum. The two solitary pancreas transplants required an operating time of 3 and 5 hr, respectively; the simultaneous pancreas kidney transplantation took 8 hr. Mean warm ischemia time of the pancreas graft was 34 min. All pancreatic transplants functioned immediately, and all recipients became insulin independent. The kidney graft, revascularized after 35 min of warm ischemia, also functioned immediately. No patient had complications during or after surgery. At the longer follow-up of 10, 8, and 6 months, respectively, all recipients are alive with normal graft function. We have shown the feasibility of laparoscopic robot-assisted solitary pancreas and simultaneous pancreas and kidney transplantation. If the safety and feasibility of this procedure can be confirmed by larger series, laparoscopic robot-assisted pancreas transplantation could become a new option for diabetic patients needing beta-cell replacement.

Single-incision laparoscopic total gastrectomy for gastric cancer has recently been reported by Seoul National University Bundang Hospital. However, this is not a popular procedure primarily because of the technical difficulties involved in achieving consistent intracorporeal esophagojejunostomy. At Seoul National University Bundang Hospital, we recently introduced a simple, easy-to-use, low-profile laparoscopic manual scope holder that enables the maintenance of a stable field of view, the most demanding condition in single-port gastrectomy. In this technical report, we describe in detail the world's first solo single-incision laparoscopic total gastrectomy with D1+ lymph node dissection and intracorporeal esophagojejunostomy for proximal early gastric cancer.

mortalidade, factível cirurgicamente pela via laparoscópica e passível de ser ofertada como opção operatória ao tratamento da diabetes mellitus tipo 2.INTRODUCTION: There is an evidence that the best results in terms of resolution of diabetes in morbidly obese patients are achieved with bilio-pancreatic bypass, especially the duodenal switch. These operations are characterized by partial gastrectomy and the rapid transit of food into the distal ileum through derivation of a significant segment of small intestine. The idea of performing the technique presented here was based on these principles. METHOD: The procedures are usually performed laparoscopically, after establishment of a pneumoperitoneum at 12-15 mmHg and introduction of six trocars. The patient is initially positioned in 30° reverse Trendelenburg with the surgeon on the right side of the patient. The sleeve gastrectomy is performed using the anatomical distal trifurcation of the anterior vagus nerve as a reference. The devascularization of the greater curvature is performed and extends to the oesophagogastric junction. With an intra-gastric calibration tube of 20 mm positioned along the lesser curvature, gastric resection starts at the proximal antrum with linear stapler up to oesophagogastric angle. An invaginating running suture is also performed. To perform the ileal interposition in the proximal jejunum, it is divided 20-30 cm distally with a 45-mm linear stapler. The cecum is identified and the distal ileum transected 30cm proximal to the ileocecal valve. A 170 to 200 cm of ileum was measured proximally along the anti-mesenteric border using a 10-cm marked atraumatic grasper, and transected with a 45-mm linear stapler. This segment of ileum is interposed in an isoperistaltic way into the proximal jejunum, previously divided. Next are perform three side-to-side enteroanastomosis. The first enteroanastomosis is the ileo-ileostomy, then the jejuno-ileostomy and finally, the ileo-jejunostomy. All three

Five patients with recurrent pneumonia after gastrectomy were studied by upper digestive tract scintigraphy. Severe gastroesophageal reflux was noted in three of the five patients in the supine position. In the other two patients, the same kind of reflux was easily induced by changing position. Esophageal dysfunction was suspected in four patients. The frequency of pneumonia decreased after we instructed the patients how to avoid reflux. We therefore diagnosed it as the chronic aspiration pneumonia. We concluded that upper digestive tract scintigraphy is useful for evaluating gastroesophageal reflux and esophageal function in patients after gastrectomy. (author)

Hysterectomy and laparoscopy are common surgical procedures used for the treatment of endometriosis. This study compares outcomes for women who received either procedure within the first year post initial surgery. The study used data from the Truven Health MarketScan claims databases from 2004 to 2013 to identify women aged 18-49 years who received an endometriosis-related laparoscopy or hysterectomy. Patients were excluded if they did not have continuous insurance coverage from 1 year before through 1 year after their endometriosis-related procedure, if they were diagnosed with uterine fibroids prior to or on the date of surgery (i.e., index date), or if they had a hysterectomy prior to the index date. The descriptive analyses examined differences between patients with an endometriosis-related laparoscopy or hysterectomy in regard to medications prescribed, complications, and hospitalizations during the immediate year post procedure. The final sample consisted of 24,915 women who underwent a hysterectomy and 37,308 who underwent a laparoscopy. Results revealed significant differences between the cohorts, with women who received a laparoscopy more likely to be prescribed a GnRH agonist, progestin, danazol, or an opioid analgesic in the immediate year post procedure compared to women who underwent a hysterectomy. In contrast, women who underwent a hysterectomy generally had higher complication rates. Index hospitalization rates and length of stay (LOS) were higher for women who had a hysterectomy, while post-index hospitalization rates and LOS were higher for women who had a laparoscopy. For both cohorts, post-procedure complications were associated with significantly higher hospitalization rates and longer LOS. This study indicated significantly different 1-year post-surgical outcomes for patients who underwent an endometriosis-related hysterectomy relative to a laparoscopy. Furthermore, the endometriosis patients in this analysis had a considerable risk of

Laparoscopic sleeve gastrectomy is gaining popularity in the US; however, there has been no study examining the use of sleeve gastrectomy at a national level and its impact on the use of other bariatric operations. The aim of this study was to examine contemporary changes in use and outcomes of bariatric surgery performed at academic medical centers. Using ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of morbid obesity between October 1, 2008 and September 30, 2012 were reviewed. Quartile trends in use for the 3 most commonly performed bariatric operations were examined, and a comparison of perioperative outcomes between procedures was performed within a subset of patients with minor severity of illness. A total of 60,738 bariatric procedures were examined. In 2008, the makeup of bariatric surgery consisted primarily of gastric bypass (66.8% laparoscopic, 8.6% open), followed by laparoscopic gastric banding (23.8%). In 2012, there was a precipitous increase in use of laparoscopic sleeve gastrectomy (36.3 %), with a concurrent reduction in the use of laparoscopic (56.4%) and open (3.2%) gastric bypass, and a major reduction in laparoscopic gastric banding (4.1%). The length of hospital stay, in-hospital morbidity and mortality, and costs for laparoscopic sleeve gastrectomy were found to be between those of laparoscopic gastric banding and laparoscopic gastric bypass. Within the context of academic medical centers, there has been a recent change in the makeup of bariatric surgery. There has been an increase in the use of laparoscopic sleeve gastrectomy, which has had an impact primarily on reducing the use of laparoscopic adjustable gastric banding.

Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

Ectopic jejunal pacemakers and gastric emptying after Roux gastrectomy: Effect of intestinal pacing

The aims of this study were to determine whether ectopic pacemakers are present after meals in the Roux limbs of dogs after vagotomy and Roux gastrectomy, whether these pacemakers slow gastric emptying of liquids or solids, and whether abolishing the pacemakers with electric pacing might speed any slow emptying that occurs. In six dogs that underwent vagotomy and Roux gastrectomy and in four dogs that underwent vagotomy and Billroth gastrectomy (controls), myoelectric activity of the Roux limb or duodenum was measured during gastric emptying of a 500 kcal mixed meal of 99mTc-labeled cooked egg and 111In-labeled milk. Roux dogs were tested with and without pacing of the Roux limb. Roux dogs showed ectopic pacemaker in the Roux limb that drove the pacesetter potentials of the limb in a reverse, or orad, direction during 57% of the postprandial recordings. Billroth dogs had no ectopic pacemakers (p less than 0.05). Liquids emptied more slowly in Roux dogs (half-life (t1/2) = 121 +/- 15 minutes) than in Billroth dogs (t1/2 = 43 +/- 9 minutes; p less than 0.05), but solids emptied similarly in both groups of dogs (t1/2 approximately 8 hours). Pacing the Roux limb abolished the ectopic pacemakers, restored the slow emptying of liquids to the more rapid rate found in the Billroth dogs (t1/2: paced Roux, 72 +/- 15 minutes; Billroth, 43 +/- 9 minutes; p greater than 0.05) and did not change emptying of solids. The conclusion was that ectopic pacemakers present in the Roux limb after vagotomy and Roux gastrectomy drove the limb in a reverse direction and slowed emptying of liquids after the operation. The defect was corrected by pacing the Roux limb in a forward direction

Full Text Available Introduction: Duodenal stump fistula (DSF after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure. Material and methods: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay. Results: In the period covered in this study, we performed 666 gastrectomies and observed DSF in 13 patients (1.95%. In 8 of the 13 patients (61.5% surgery was the treatment of choice and in 5 cases (38.5% conservative treatment was carried out. Postoperative mortality associated with DSF was 46.2% (6 cases. In the surgical group, 3 patients developed severe sepsis with multiple organ failure, 2 patients presented a major hematemesis which required endoscopic haemostasis, 1 patient had an evisceration and another presented a subphrenic abscess requiring percutaneous drainage. Six patients (75% died despite surgery, with 3 deaths in the first 24 hours of postoperative care. The 2 patients who survived after the second surgical procedure had a hospital stay of 45 and 84 days respectively. In the conservative treatment group the cure rate was 100% with no significant complications and an average postoperative hospital stay of 39.5 days (range, 26-65 days. Conclusion: FMD is an unusual complication but it is associated with a high morbidity and mortality. In our experience, conservative management has shown better results compared with surgical treatment.

Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy. To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort. Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer. The tasks were performed conventionally, utilizing the three devices, and robotically. Task completion times were recorded and the surgeon discomfort was evaluated using questionnaires. Task completion times were compared using nonparametric Wilcoxon signed rank test and ergonomic scores were compared using Pearson chi-square test. The use of the full laparoscopic set (ETHOS chair, three-dimensional laparoscopic camera, Radius Surgical System needle holders), resulted in a significant improvement of the completion time of the three tested tasks compared with conventional laparoscopy (psystem nullified heavy discomfort for Tasks IV and V and minimized it (6.7%) for the most demanding Task VI. Especially for Task VI, all trainees gained benefit, by using the system, in terms of task completion times and discomfort. The limited trainee robotic experience and the questionnaire subjectivity could be a potential limitation. The ergonomic laparoscopic system offers significantly improved task completion times and ergonomy than conventional laparoscopy. Furthermore, it demonstrates comparable results to robotic surgery. The study was conducted in a pelvi trainer and no patients were recruited. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Miniscrew-assisted mandibular molar distalization in a patient with skeletal class-III malocclusion: A clinical case report

Directory of Open Access Journals (Sweden)

2013-01-01

Full Text Available In nongrowing patients with mild skeletal Class-III malocclusion, premolar extraction or molar distalization in the lower arch can be done as a part of camouflage treatment. Temporary anchorage devices are widely used for this purpose because they do not produce undesirable reciprocal effects and do not depend on the patient′s cooperation. However, most reported cases in this regard have used interradicular miniscrews in the mandibular arch and these have a risk of failure as they can loosen due to collision with adjacent roots. This article showcases mandibular molar distalization utilizing miniscrews, inserted at the retromolar area to correct a Class-III problem. A 24-year-old girl with a mild skeletal Class-III malocclusion and dental Class-III molar and canine relationship bilaterally was referred for orthodontic treatment. The treatment plan included distalization of the lower molars bilaterally followed by full fixed appliance therapy, after third molar extractions. For the lower molar distalization, the miniscrews were inserted at the retromolar pad. At the end of 21 months, a Class-I molar and canine relationship, normal overjet and overbite were obtained. The average amount of distalization of mandibular first molar was 3.2 mm at the crown level. In conclusion, placing miniscrews at the retromolar pad area for lower molar distalization was found to be a simple and effective method for correcting anterior cross bite and mandibular anterior crowding or protrusion, without the need for patient compliance.

Laparoscopy and dye test is an important investigation in the evaluation of infertile women which has been underutilised in our practice. This review is aimed at determining whether the findings of this procedure are substantial enough to make it a first line evaluation for infertile women. A review of the laparoscopic findings in infertile women who presented for evaluation and treatment at a private fertility centre was carried out. A total of 253 day-case laparoscopy and dye test procedures were reviewed, 115 (45.0%) were done for primary infertility, 137 (54.5%) for secondary infertility and 1 (0.4%) for primary amenorrhoea and infertility. The mean period of infertility was 4.5 years with a range of 2-10 years and the women were aged between 19 and 52 years. Analysis of the result showed that 100 (39.5%) women had normal patent tubes while 153 (60.4%) had tubal pathologies like bilateral tubal occlusion in 97 (38.3%) and unilateral tubal occlusion in 56 (22.1%) women. Pelvic adhesion of varying degrees of severity was present in 108 (42.7%) women. Bilateral tubal occlusion was more common in nulliparous women and those aged between 30-39 years. One or both ovaries were normal (functional) in 189 (74.7%) women. Altogether, only 43 (17.0%) women were "normal" (had patent tubes, functional ovary and no pelvic adhesion). Additional pelvic pathology was present in 142 (56.1%) women. The commonest was uterine fibroid (leiomyomata) of various sizes in 100 (39.5%) of the women, followed by ovarian cyst in 56 (22.2%) and endometriosis in 11 (4.4%) women. Other pathologies observed include uterine abnormalities and unruptured ectopic pregnancy. Only 16 (37.2%) of the 43 "normal" women had no additional pelvic pathology. The high prevalence o tuboperitoneal factor and additional pelvic pathology in these infertile women reveal the importance of laparoscopic evaluation. We recommend the use of laparoscopy and dye test as a first line investigation in our environment to

Full Text Available Postoperative leak is a serious complication of bariatric surgery and often results in significant morbidity and mortality. Stent placement is a less invasive alternative to surgery for the treatment of bariatric surgical leak. We evaluated the efficacy and complications of covered self-expandable metal stents (SEMS in the treatment of post-bariatric surgical leak. We retrospectively reviewed patients who underwent stent placement for leak after bariatric surgery. Leak was diagnosed by upper gastrointestinal series or was visualized during the endoscopy. We examined the timing of stent placement, size of the leak, stent migration and its complications, total stent treatment duration, and treatment outcome. Between January 2011 and April 2015, seven patients underwent covered SEMS placement for leak after bariatric surgery, including laparoscopic sleeve gastrectomy (LSG (n = 5 and laparoscopic loop duodenojejunal bypass with sleeve gastrectomy (LDJB-SG (n = 2. A stent was placed in one patient for infection control and bridging to revisional surgery. Among the other six patients, one patient who received stent placement one year after leak diagnosis failed to achieve leak closure, and five patients with early stent placement achieved leak closure. Three patients with small leak achieved leak closure more quickly. Stent migration was found in six patients, and associated ulcers occurred in five patients. We conclude that stenting is effective in the management of staple-line leaks following LSG and LDJB-SG. Stent migration and associated ulcers are common after stent placement. Early stent removal can be achieved in patients with small leaks.

We sought to compare robotic vs laparoscopic surgery in regards to patient reported postoperative pain and quality of life. This was a prospective study of patients who presented for treatment of a new gynecologic disease requiring minimally invasive surgical intervention. All subjects were asked to take the validated Brief Pain Inventory-Short Form at 3 time points to assess pain and its effect on quality of life. Statistical analyses were performed using Pearson x(2) and Student's t test. One hundred eleven were included in the analysis of which 56 patients underwent robotic assisted surgery and 55 patients underwent laparoscopic surgery. There was no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. There was a statistically significant difference found at the delayed postoperative period when evaluating interference of sleep, favoring laparoscopy (ROB 2.0 vs LSC 1.0; P = .03). There were no differences found between the robotic and laparoscopic groups of patients receiving narcotics (56 vs 53, P = .24, respectively), route of administration of narcotics (47 vs 45, P > .99, respectively), or administration of nonsteroidal antiinflammatory medications (27 vs 21, P = .33, respectively). Our results demonstrate no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. Furthermore, pain did not appear to interfere consistently with any daily activity of living. Interference of sleep needs to be further evaluated after controlling for bilateral salpingo-oophorectomy. Copyright © 2015 Elsevier Inc. All rights reserved.

The purpose of the present study was to investigate on the acceptance and frequency of laparoscopic surgery for the management of acute and chronic bowel obstruction in a general patient population in German hospitals. To receive an authoritative opinion on laparoscopic treatment of bowel obstruction in Germany, a cross-sectional online study was conducted. We designed an online-based survey, supported by the German College of Surgeons (Berufsverband der Deutschen Chirurgen, BDC) to get multi-institutional-based data from various level providers of patient care. Between January and February 2014, we received completed questionnaires from 235 individuals (16.7 %). The participating surgeons were a representative sample of German hospitals with regard to hospital size, level of center size, and localization. A total of 74.9 % (n = 176) of all responders stated to use laparoscopy as the initial step of exploration in expected bowel obstruction. This procedure was highly statistically associated with the frequency of overall laparoscopic interventions and laparoscopic experience. The overall conversion rate was reported to be 29.4 %. This survey, investigating on the use of laparoscopic exploration or interventions in bowel obstruction, was able to show that by now, a majority of the responding surgeons accept laparoscopy as an initial step for exploration of the abdomen in the case of bowel obstruction. Laparoscopy was considered to be at least comparable to open surgery in an emergency setting. Furthermore, data analysis demonstrated generally accepted advantages and disadvantages of the laparoscopic approach. Indications for or against laparoscopy are made after careful consideration in each individual case.

Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Several methods have been proposed for repairing a distal penile erosion. We present our preliminary experience in "Distal corporoplasty" technique. We enrolled 18 consecutive patients whose underwent a distal corporoplasty with simultaneous reimplantation of an "AMS 700 inflatable penile prosthesis (LGX)" from January 2013 to November 2015 at our hospital. All procedures were performed by a single surgical team. Intraoperative and postoperative complications have been classified and reported according to Satava6 and Clavien-Dindo (CD) system.7 Mean values with standard deviations (±SD) were computed and reported for all items. Mean age of the patients was 53.61 (±11.90) years. Mean body max index (BMI) was 24.22 (±2.51). Mean operative time was 85.2 (±13.1) minutes. Blood losses were minimal. No intraoperative complications are reported according to Satava classification. Four out of 18 patients (22.22%) experienced postoperative complications according to CD system. All patients had sexual intercourse for the first time postsurgery after a mean of 59.11 ± 2.08 days. Mean follow-up was 22.11 (±9.95). Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Distal corporoplasty was first described by Mulcahy. He reported a series of 14 patients with a follow-up of about 2 years with optimal functional outcomes. Moreover, distal corporoplasty resulted in shorter operative time, better function, less pain, and fewer recurrences than Gortex windsock repair.10 In our experience, distal corporoplasty is a simple and safe procedure in the treatment of distal cylinders extrusion when the prosthetic material is not exposed to the exterior.

Continuous efforts to reduce the numbers and size of incisions led to the emergence of a new technique, single-incision laparoscopic surgery (SILS). It has been rapidly accepted as the preferred surgical approach in the colorectal area. In the age of SILS, what is the role of hand-assisted laparoscopic surgery (HALS)? We introduce the way to take advantage of it, as an effective alternative to avoid open conversion. This is a retrospective review of prospectively collected data of SILS colectomies performed by a single surgeon in Samsung Medical Center between August 2009 and December 2012. Out of 631 cases of SILS colectomy, 47 cases needed some changes from the initial approach. Among these, five cases were converted to HALS. Four of them were completed successfully without the need for open conversion. One patient with rectosigmoid colon cancer invading bladder was finally opened to avoid vesical trigone injury. The mean operation time of the 4 patients was 265.0 minutes. The mean estimated blood loss was 587.5 mL. The postoperative complication rate associated with the operation was 25%. Conversion from SILS to HALS in colorectal surgery was feasible and effective. It seemed to add minimal morbidity while preserving advantages of minimally invasive surgery. It could be considered an alternative to open conversion in cases of SILS, especially when the conversion to conventional laparoscopy does not seem to be helpful.

Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

The ferric chloride intoxication is frequently caused by accident. Its toxicity is generally underrated, which can lead to fatal evolution or irreversible consequences. In this case, the caustic condition of the substance is related to the toxic properties of iron. A 36-year-old male patient arrives by ambulance indicating sensory deterioration. He presents erosive injuries in the buccal cavity and in the oropharynx, brownish teeth and metabolic acidosis. Toxicology tests and ferritin blood dosage are requested, which show a result from 1400 mg/dl. The symptoms are interpreted as acute iron intoxication. Due to the unfavorable evolution of his condition, an abdominal and pelvic CT scan are performed, which show extensive pneumoperitoneum and free fluid in the abdominal cavity. An exploratory laparotomy, a total gastrectomy with esophagostomy and feeding jejunostomy, washing and drainage due to perforated gastric necrosis caused by caustic ingestion are performed. In our country, there is a high rate of intoxication caused by iron compounds, although it is not statistically measured. Nevertheless, the ferric chloride intoxication is extremely infrequent. The ingestion of this product leads to complications, which are associated with the iron concentration and its condition as a caustic agent. The surgical indications in the presence of intoxication caused by iron compounds are: stomach evacuation of iron, gastric necrosis, perforation or peritonitis and stenosis. Early or prophylactic gastrectomy is contraindicated. However, if complications that require immediate surgical intervention arise, there should be no hesitation and the corresponding procedure should be performed.

Introduction: Diagnostic laparoscopy allows the visual examination and documentation of intra-abdominal organs in order to detect any pathology. It is an important tool for final minimally invasive exploration of patients with abdominal tuberculosis, the diagnosis of which remains uncertain despite employing the requisite laboratory and non-invasive imaging investigations. Objective: To determine the frequency of peritoneal tuberculosis using diagnostic laparoscopy in clinically suspected cases of peritoneal tuberculosis. Study Design: Cross sectional survey. Setting: The study was conducted in all the four Surgical Wards on surgical floor of Mayo Hospital Lahore. Duration of Study with Dates: Six months (1st July 2009 to 31st December 2009). Material and Methods: 35 Patients aged between 13-60 years with clinical suspicion of peritoneal tuberculosis were selected. The patients underwent the procedure accordingly. Per operative diagnosis of peritoneal tuberculosis made on the basis of presence of any or all of the operative (laparoscopic) findings such as multiple peritoneal adhesions, fibrous bands, whitish peritoneal tubercles, omental thickening and ascites. Diagnosis was confirmed with histopathology of peritoneal tissue biopsy. Also the biochemical analysis and culture sensitivity of ascetic fluid was routinely performed if any ascites is present. Results: Out of 35 patients, 40% were males and 60% females with mean age of 24.91+-6.69 years. The Laparoscopic findings of peritoneal tuberculosis were whitish peritoneal tubercles (57.2%) peritoneal adhesions (28.6%), ascites (17.2%), omental thickening (14.3%), fibrous bands (11.4%) and swollen edematous appendix (5.7%). Eighty percent were labeled with diagnosis of peritoneal tuberculosis on basis of diagnostic laparoscopy. These patients were confirmed to have peritoneal tuberculosis on histopathology of tissue biopsy. Conclusion: Diagnostic laparoscopy is useful in patients with suspected peritoneal

A 72-year-old man who had undergone a total gastrectomy with a Roux-en-Y esophagojejunostomy for gastric cancer 6 years earlier presented to our hospital with massive hematemesis and melena. Endoscopic examination indicated esophageal varices with cherry-red spots and hemorrhage arising from beyond the anastomosis. Abdominal contrast-enhanced computed tomography and angiography revealed a dilated vein in the elevated jejunal limb supplying the varices. Percutaneous trans-hepatic obliteration (PTO) of the varices through the jejunal vein was performed using microcoils, ethanolamine oleate, and gelatin sponge cubes. Ten days after the procedure, endoscopic examination revealed reduction and thrombosis of the varices. We consider PTO to be an effective alternative method for treating ruptured esophagojejunal varices after total gastrectomy

Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

Hand surgeons have been hesitant to perform distal digital replantation because of the technical challenges and the perception of a high cost-to-benefit ratio. Recent studies, however, have shown high survival rates and excellent functional and aesthetic results, providing renewed enthusiasm for distal replantation. The authors reviewed the literature and summarize key points regarding the surgical treatment, perioperative care, and outcomes of distal digital replantation. They describe specific techniques and considerations for surgical repair in each of four distal zones as described by Sebastin and Chung. Zone 1A replantation involves an artery-only anastomosis of a longitudinal pulp artery. Venous anastomosis first becomes possible in zone 1B. Zone 1C involves periarticular amputations where arthrodesis of the distal interphalangeal joint is usually indicated. Repair of the artery, vein, and nerve is technically optimal in zone 1D, where venous anastomosis should be performed. Overall, survival rates for distal digital replantation are similar to those reported for more proximal replantation. The literature reports good outcomes regarding nail salvage, fingertip sensibility, and range of motion, with restoration of length and aesthetic appearance. Distal replantation performed at institutions that specialize in microsurgery and specifically tailored to the level of injury is associated with good survival, function, and patient satisfaction and superior aesthetic outcome. More prospective data are needed to evaluate the cost of treatment, psychological outcomes, and functional outcomes of distal replantation compared with revision amputation.

Concurrent Mesh Repair of a Morgagni and Umbilical Hernia during a Laparoscopic Sleeve Gastrectomy in a Morbidly Obese Individual

Full Text Available Morgagni Hernia is a rare form of diaphragmatic hernia. It is mainly asymptomatic and often identified incidentally during surgery. Tension-free synthetic mesh repair is the preferred treatment modality. However, the use of synthetic mesh concurrently during a clean-contaminated surgery such as sleeve gastrectomy remains controversial due to the remote possibility of mesh infection. A middle-aged female 2 with BMI of 47 Kg/m was admitted electively for laparoscopic sleeve gastrectomy with concurrent umbilical hernia repair. Intra-operatively, a left Morgagni Hernia containing omentum and a segment of transverse colon was noted. She underwent a laparoscopic sleeve gastrectomy and simultaneous laparoscopic tension-free composite mesh repair of both Morgagni and umbilical hernia. Outpatient review three months later revealed excess weight loss of almost 30% with no recurrence of either hernia. In conclusion, the advantages of concurrent hernia repair during bariatric surgery outweigh the risk of mesh infection and should be performed to prevent future risk of visceral herniation and strangulation. Laparoscopic mesh repair of a Morgagni Hernia and umbilical hernia in the setting of an electively planned sleeve gastrectomy is feasible, effective and safe in the hands of a trained laparoscopic surgeon.

The late postoperative complications in patients after gastrectomy include anemia and metabolic bone disorders. We studied to determine whether gastric surgery is associated with metabolic bone disease. Vertebral BMD was measured in 55 patients after gastric resection by using DEQCT (dual energy quantitative CT). Forty patients were symptomatic, having bone or joint pain, history of bone fracture, or dental caries. The control group consisted of 161 patients without metabolic bone disorders. Forty percent of the patients with either the symptoms or history of bone fracture or dental caries, and 20% of the patients without the symptoms or the history showed decreased BMD. BMD was significantly lower in males in their 60s and in females in their 50s and 70s than BMD in age-matched control groups. When male subjects were grouped according to the years following the operation (1-5, 6-10, 11-15, 16-20 years), BMD was found to be decreased in 27%, 29%, 40% and 50% of the patients in each group, respectively, and the degree of the decrease tended to be greater with increasing time after surgery. Higher incidence of decreased BMD was found in the patients after total gastrectomy when compared with those after subtotal gastrecotmy. Among the patients with subtotal gastrectomy, the incidence of decreased BMD was higher in patients with Billroth II anastomosis than in those with Billroth I anastomosis. In cases with compression fracture on thoracolumbar radiographs, BMD was significantly lower in comparison with cases with no fracture. It was difficult to differentiate between osteomalacia and osteoporosis only by the thoracolumbar radiographs. While the clinical information such as patients' complaints, histories of fracture and laboratory findings are important to evaluate the bone changes following gastric resection. BMD measurement is most useful in quantitatively determining the degree of bone loss after gastrectomy. (author)

Initial staging of gastric cancer consists of computed tomography (CT) and gastroscopy. In locally advanced (cT3-4) gastric cancer, fluorodeoxyglucose positron emission tomography with CT (FDG-PET/CT or PET) and staging laparoscopy (SL) may have a role in staging, but evidence is scarce. The aim of this study is to evaluate the impact and cost-effectiveness of PET and SL in addition to initial staging in patients with locally advanced gastric cancer. This prospective observational cohort study will include all patients with a surgically resectable, advanced gastric adenocarcinoma (cT3-4b, N0-3, M0), that are scheduled for treatment with curative intent after initial staging with gastroscopy and CT. The modalities to be investigated in this study is the addition of PET and SL. The primary outcome of this study is the proportion of patients in whom the PET or SL lead to a change in treatment strategy. Secondary outcome parameters are: diagnostic performance, morbidity and mortality, quality of life, and cost-effectiveness of these additional diagnostic modalities. The study recently started in August 2017 with a duration of 36 months. At least 239 patients need to be included in this study to demonstrate that the diagnostic modalities are break-even. Based on the annual number of gastrectomies in the participating centers, it is estimated that approximately 543 patients are included in this study. In this study, it is hypothesized that performing PET and SL for locally advanced gastric adenocarcinomas results in a change of treatment strategy in 27% of patients and an annual cost-reduction in the Netherlands of €916.438 in this patient group by reducing futile treatment. The results of this study may be applicable to all countries with comparable treatment algorithms and health care systems. NCT03208621 . This trial was registered prospectively on June 30, 2017.

It is estimated that there are nearly 40 million people with the human immunodeficiency virus (HIV) worldwide. Due to the advent of antiretroviral drugs, it has been observed increasing in obesity and metabolic rates among patients undergoing treatment. Thus, numerous surgical therapies for weight loss are proposed for continuous improvement in health of patients with HIV, being the vertical gastrectomy an option for intact intestinal transit. To evaluate the applicability of the vertical gastrectomy in patients with morbid obesity and HIV. Was conducted a systematic review of the literature, in the electronic databases Scopus, Pubmed, Cinahl, Scielo, Cochrane and Lilacs, from 1998 to 2015. MeSH headings used in data collection were "Gastrectomy" and "Morbid obesity" being combined with the descriptor "HIV". Were found 2148 articles in Scopus, 1234 in PubMed and 784 in Cinahl. The articles were analyzed by the Jadad Quality Scale, being reduced to 40 articles, subsequently reassessed using an elaborated form by the Critical Appraisal Skills Programme (CASP), reaching 12 articles in the end. It was found that vertical gastrectomy constitutes a safe and effective method, with low mortality and low rate of postoperative complications, being recommended as surgical technique in patients with obesity, HIV and comorbidities.

We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC. Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU or hand-assisted (HALNU. The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU. Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

Sleeve gastrectomy is increasingly used in the treatment of morbid obesity, but its long-term outcome vs the standard Roux-en-Y gastric bypass procedure is unknown. To determine whether there are differences between sleeve gastrectomy and Roux-en-Y gastric bypass in terms of weight loss, changes in comorbidities, increase in quality of life, and adverse events. The Swiss Multicenter Bypass or Sleeve Study (SM-BOSS), a 2-group randomized trial, was conducted from January 2007 until November 2011 (last follow-up in March 2017). Of 3971 morbidly obese patients evaluated for bariatric surgery at 4 Swiss bariatric centers, 217 patients were enrolled and randomly assigned to sleeve gastrectomy or Roux-en-Y gastric bypass with a 5-year follow-up period. Patients were randomly assigned to undergo laparoscopic sleeve gastrectomy (n = 107) or laparoscopic Roux-en-Y gastric bypass (n = 110). The primary end point was weight loss, expressed as percentage excess body mass index (BMI) loss. Exploratory end points were changes in comorbidities and adverse events. Among the 217 patients (mean age, 45.5 years; 72% women; mean BMI, 43.9) 205 (94.5%) completed the trial. Excess BMI loss was not significantly different at 5 years: for sleeve gastrectomy, 61.1%, vs Roux-en-Y gastric bypass, 68.3% (absolute difference, -7.18%; 95% CI, -14.30% to -0.06%; P = .22 after adjustment for multiple comparisons). Gastric reflux remission was observed more frequently after Roux-en-Y gastric bypass (60.4%) than after sleeve gastrectomy (25.0%). Gastric reflux worsened (more symptoms or increase in therapy) more often after sleeve gastrectomy (31.8%) than after Roux-en-Y gastric bypass (6.3%). The number of patients with reoperations or interventions was 16/101 (15.8%) after sleeve gastrectomy and 23/104 (22.1%) after Roux-en-Y gastric bypass. Among patients with morbid obesity, there was no significant difference in excess BMI loss between laparoscopic sleeve gastrectomy and laparoscopic Roux

To compare the mid-term follow-up angiographic findings in distal internal carotid artery (ICA) aneurysms treated by stent-assisted coil embolization using the Enterprise or Neuroform stent. We included 68 patients with 70 aneurysms: 31 cases with Enterprise and 39 cases with Neuroform. Inclusion criteria were 1) location of the stent within the distal ICA, including the carotid siphon; 2) follow-up angiogram after > 6 months, and 3) single use of the stent for 1 parent artery. The patients' mean age was 54.9 years (16 male and 52 female). Mean follow-up duration was 9.1 months. At follow-up, there were intraluminal filling defects of the parent artery in 19.4% of the Enterprise group and no filling defect in the Neuroform group. There was no significant in-stent stenosis in either group. Straightening of the parent artery was seen in 35.5% of the Enterprise group and 20.5% of the Neuroform group. Two Enterprise cases showed delayed migration. The Enterprise showed statistically significant intraluminal filling defects of the parent artery compared with the Neuroform. The rates of significant in-stent stenosis and straightening of the parent artery were not significantly different between the Enterprise and the Neuroform groups.

Gastro-oesophageal reflux disease (GORD) is a common obesity-related co-morbidity that is assessed objectively by 24-h pH monitoring. Some concerns have been raised regarding the risk of de novo GORD or exacerbation of pre-existing GORD after laparoscopic sleeve gastrectomy. Here, 24-h pH monitoring was used to assess the influence of laparoscopic sleeve gastrectomy on postoperative GORD in obese patients with or without preoperative GORD. From July 2012 to September 2014, all patients scheduled for laparoscopic sleeve gastrectomy were invited to participate in a prospective follow-up. Patients who underwent preoperative 24-h pH monitoring were asked to repeat the examination 6 months after operation. GORD was defined as an oesophageal pH < 4 for at least 4·2 per cent of the total time recorded. Of 89 patients, 76 had preoperative pH monitoring for GORD evaluation and 50 had postoperative reassessment. Patients without (group 1, 29 patients) or with (group 2, 21 patients) preoperative GORD were similar regarding age, sex ratio and body mass index. In group 1, the median (i.q.r.) total time at pH < 4 was significantly higher after surgery than before: 5·6 (2·5-9·5) versus 1·6 (0·7-2·9) per cent (P < 0·001). Twenty of the 29 patients experienced de novo GORD as determined by 24-h pH monitoring (P < 0·001). In group 2, total time at pH < 4 after surgery was no different from the preoperative value: 5·9 (3·9-10·7) versus 7·7 (5·2-10·3) per cent (P = 0·296). Laparoscopic sleeve gastrectomy was associated with de novo GORD in over two-thirds of patients, but did not seem to exacerbate existing GORD. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

Robotic-assisted versus laparoscopic colorectal surgery: a meta-analysis of four randomized controlled trials

Science.gov (United States)

2014-01-01

Background Robotic-assisted laparoscopy is popularly performed for colorectal disease. The objective of this meta-analysis was to compare the safety and efficacy of robotic-assisted colorectal surgery (RCS) and laparoscopic colorectal surgery (LCS) for colorectal disease based on randomized controlled trial studies. Methods Literature searches of electronic databases (Pubmed, Web of Science, and Cochrane Library) were performed to identify randomized controlled trial studies that compared the clinical or oncologic outcomes of RCS and LCS. This meta-analysis was performed using the Review Manager (RevMan) software (version 5.2) that is provided by the Cochrane Collaboration. The data used were mean differences and odds ratios for continuous and dichotomous variables, respectively. Fixed-effects or random-effects models were adopted according to heterogeneity. Results Four randomized controlled trial studies were identified for this meta-analysis. In total, 110 patients underwent RCS, and 116 patients underwent LCS. The results revealed that estimated blood losses (EBLs), conversion rates and times to the recovery of bowel function were significantly reduced following RCS compared with LCS. There were no significant differences in complication rates, lengths of hospital stays, proximal margins, distal margins or harvested lymph nodes between the two techniques. Conclusions RCS is a promising technique and is a safe and effective alternative to LCS for colorectal surgery. The advantages of RCS include reduced EBLs, lower conversion rates and shorter times to the recovery of bowel function. Further studies are required to define the financial effects of RCS and the effects of RCS on long-term oncologic outcomes. PMID:24767102

The objective of this prospective study was to describe the clinical effects of a bone-supported molar distalizing appliance, the dual-force distalizer. The study group included 16 patients (mean age, 14.3 years) with Class II molar relationships. Study models and lateral cephalograms were taken before and after the distalizing movement to record significant dental and skeletal changes (Wilcoxon test). The average distalization time was 5 months, with a movement rate of 1.2 mm per month; the distalization amounts were 5.9 +/- 1.72 mm at the crown level and 4.4 +/- 1.41 mm at the furcation level. The average molar inclination was 5.6 degrees +/- 3.7 degrees ; this was less than the amount of inclination generated by bone-supported appliances that use single distalizing forces. The correlation between inclination and distalization was not significant, indicating predominantly bodily movement. The teeth anterior to the first molar moved distally also; the second premolars distalized an average of 4.26 mm, and the incisors retruded by 0.53 mm. The dual-force distalizer is a valid alternative distalizing appliance that generates controlled molar distalization with a good rate of movement and no loss of anchorage.

Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success. We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease. Also, we looked for variables related to a higher chance of occult metastasis. Patients with PDAC submitted to staging laparoscopy either immediately before pancreatectomy or as a separate procedure between January 2010 and December 2016 were included. None presented gross metastatic disease at initial staging. We used logistic regression to search for variables associated with metastatic disease. The study population consisted of 63 patients. Among all patients, nine (16.7%) had occult metastases at laparoscopy. Unresectable tumor (Odds ratio = 18.0, P = 0.03), increasing tumor size (Odds ratio = 1.36, P = 0.01), and abdominal pain (Odds ratio = 5.6, P = 0.04) significantly predicted the risk of occult metastases in univariate analysis. In multivariate analysis, only tumor size predicted the risk of occult metastases. Laparoscopy remains a valuable tool in PDAC staging. Patients with either large or unresectable tumors, or presenting with abdominal pain present the highest risk for occult intra-abdominal metastases. © 2018 Wiley Periodicals, Inc.

To assess the difference between early enteral nutrition (EEN group) and total parenteral nutrition (TPN group) after total gastrectomy for gastric cancer. The nutrition index, liver function, patient generated subjective global assessment (PG-SGA) score, the post-operation complications, the hospital stay and hospitalization expense of the postoperative patient after total gastrectomy, admitted to our Department of Surgery from May 2011 to May 2013 were analyzed retrospectively. A total of 72 patients including 37 cases in the EEN group and 35 cases in the TPN group were recruited. Hypoalbuminemia gradually improved in the EEN group about 3-5 days, but it did not increase until average 21 days in the TPN group. The body weight decreased in the EEN group during the first 2 weeks and recovered gradually in 21 days; body weight in the TPN group was significantly lower than the EEN group at 21 days (pnutrition indicators. The incidence of complications in the EEN group and TPN group were 8.1% and 25.7% respectively, with no significant differences (p>0.05). The days of hospital stays in the EEN and in the TPN group were up to 12.2 ± 2.5 d vs 14.9 ± 2.9 d (pgastric cancer.

Food intake and nutritional status was studied in 67 patients, who had had a gastrectomy 2-30 years earlier, and in a randomly selected, matched group of healthy persons. The gastrectomized patients weighed less than the control persons (women 56.4 +/- 9.5 vs 61.4 +/- 6.9 kg; P less than 0.05; men.......01). The serum concentration of alkaline phosphatase was raised and the concentration of calcium, phosphorus and 25-hydroxycholecalciferol reduced in the gastrectomized group. None of these results could be explained from the nutritional study as both the intake of energy and protein and the intake of calcium...

Deomir Germano Bassi

Full Text Available Reflux esophagitis and Barrett's esophagus after total gastrectomy is related to reconstructive procedure of intestinal continuity. The Roux-en-Y operation with length of limb of 40 cm occasionally is not enough to prevent biliary reflux to distal esophagus. Barrett's esophagus is thought to develop as a consequence of biliary reflux and has a malignant potential. Symptoms of retroesternal burning and dysphagia that does not improve with conservative management has to be treated by an operative procedure. To prevent biliary reflux to distal esophagus after total gastrectomy the lenght of limb of Roux-en-Y should be at lest 60 cm.

Our objective was to evaluate the usefulness of CT virtual preoperative planning in the surgical repositioning of malunited distal radius fracture. Eleven patients with malunited distal radius fracture underwent multislice CT of both wrists. A preoperative workup was performed in a virtual reality environment created from the CT data sets. Virtual planning comprised three main procedures, carrying out the virtual osteotomy of the radius, prediction of the final position of the distal radius after osteotomy and computer-assisted manufacturing of a repositioning device, which was later placed at the surgical osteotomy site to reposition objectively the distal radius fragment before fixation with the osteosynthesis. All patients tolerated the surgical procedure well. During surgery, the orthopedic surgeons were not required in any of the cases to alter the position of the distal radius that was determined by the repositioning device. At postoperative follow-up, the anatomic relationship of the distal radius was restored (radial inclination, 21.4 ; volar tilt, 10.3 ; ulnar variance, 0.5 mm). Clinically, a significant improvement of pronation (P=0.012), supination (P=0.01), flexion (P=0.001) and extension (P=0.006) was achieved. Pain decreased from 54 to 7 points. CT virtual reality is a valuable adjunct for the preoperative workup and surgical reposition of malunited distal radius fractures. (orig.)

The restoration of the digestive tract by performing an esophago-jejunal anastomosis (EJA) is a crucial step of the total gastric and distal esophagus surgical resection for esophago-gastric junction (EGJ) cancer. We have already ideated and tested on a cadaver model an innovative technique which could be useful to minimize the risk of complications related to the phase of securing the anvil of the circular stapler prior to perform the EJA. This surgical technique was derived from the well-known "double-stapling Knight and Griffen" one that was described for the rectal resection. We used the following described technique in 20 patients with EGJ cancer and it is efficient, reliable, safe, easy to learn and easy to perform. From August 2014 to May 2015, 20 patients (14 male and 6 female) underwent surgery for esophagogastric junction cancer: In all patients a distal esophageal resection and total gastrectomy was performed. Through the trans-hiatal access, the free margins of the esophageal stump were suspended and the anvil of a circular stapler on a new dedicated and registered support bar was inserted into the lumen. Subsequently, the linear suturing stapler is closed over the bar and then fired to suture the distal stump of the esophagus; after the confirmation of a negative margin, the bar is retracted and the push-rod of the anvil is pulled out through the linear suture. Finally, the anastomosis is performed with the classic technique by using a circular stapler. No postoperative mortality occurred; postoperative course has been uneventful for 18 patients. One patient developed anastomotic fistula that has been treated conservatively with endoscopic prothesis, removed after 20 days. One patient developed in 3 POD myocardial infarction Mean Hospital stay has been 14 days (range 7-20 days). The aim of our new procedure is the insertion the anvil of a common circular stapler without handsewn securing; this is to reduce the technical difficulties related to the hand

To evaluate systemic markers of immune and stress responses after bilateral adnexectomy performed using 2 different laparoscopic techniques in pigs. Prospective comparative study (Canadian Task Force classification II-2). University teaching hospital, research hospital, and tertiary care center. Twenty female Yorkshire pigs undergoing laparoscopic surgery. Animals underwent bilateral salpingo-oophorectomy (ovary and fallopian tube extraction), performed via conventional laparoscopy (n = 10) or the single-port access approach (n = 10). Injury provokes an acute-phase response, primarily produced by cytokines. The inflammatory response has been well described for major surgery and for conventional laparoscopy; however, little information is currently available for single-port laparoscopy, and none in the gynecologic field. This is the first study to compare serum cytokine interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) concentrations at baseline and in the early postoperative period (2, 4, and 20 hours) after bilateral salpingo-oophorectomy performed via conventional laparoscopy (n = 10) or single-port access (n = 10) in a porcine model. The stress response was measured using glucose and cortisol concentrations and the animals' response to surgery via a 6-category observation-based behavior test. Both IL-6 and TNF-α concentrations peaked at 4 hours after surgery, and were significantly lower in the single-port access group (p = .02) than in the conventional laparoscopy group (p = .02). In addition, in the single-port access group, concentrations of stress markers were slightly lower at all intervals recorded and were statistically significant at 2 hours after the operation for glucose concentration (mean [SD], 164.50 [26.73] mg/dL for conventional laparoscopy vs 86.50 [17.93] mg/dL for single-port access; p = .02). Evidence of improved inflammatory and stress responses was recorded in the minimally invasive single-port group. More clinical

To explore the feasibility of subserosal injection of carbon nanoparticle via venous infusion needle to label lymph node and its application value in laparoscopic radical gastrectomy. Forty patients with gastric cancer were randomly divided into two groups (carbon nanoparticle group and control group). Subserosal injection of carbon nanoparticle around the tumor was performed via venous infusion needle laparoscopically at the beginning of surgery in carbon nanoparticles group, while the patients routinely underwent laparoscopic radical gastrectomy in control group. Results of harvested lymph nodes were compared between the two groups. The perioperative complications and the side effect of carbon nanoparticle were also evaluated. The average number of harvested lymph node in carbon nanoparticle group (31.7±7.6) was significantly higher than that in control group (19.8±6.1, Pinjection of carbon nanoparticle via venous infusion needle to label lymph nodes during laparoscopic radical gastrectomy is safe and feasible. It can increase the number of harvested lymph node, especially the small node.

The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. Twenty-one patients developed benign strictures at the site of anastomosis. The majority of strictures occurred within 1 year after surgery (95.2%). The median duration to stenosis after surgery was 1.70 months (range, 0.17 to 23.97 months). The success rate of the first endoscopic dilation was 61.9%. Between the restenosis group (n=8) and the no restenosis group (n=13), there were no significant differences in the body mass index (22.82 kg/m(2) vs 22.46 kg/m(2)), interval to symptom onset (73.9 days vs 109.3 days), interval to treatment (84.6 days vs 115.6 days), maximal balloon diameter (14.12 mm vs 15.62 mm), number of balloon dilation sessions (1.75 vs 1.31), location of gastric cancer or type of surgery. One patient required surgery because of stricture refractory to repeated dilation. Endoscopic dilation is a highly effective treatment for benign anastomotic strictures after radical gastrectomy for gastric cancer and should be considered a primary intervention prior to proceeding with surgical revision.

Full Text Available Introduction : Celiac trunk (CT compression syndrome caused by the median arcuate ligament (MAL is a rarely diagnosed disease because of its nonspecific symptoms, which cause a delay in the correct diagnosis. Intestinal ischemia occurs, which causes symptoms of abdominal angina. One method of treatment for this disease is surgical release of the CT – the intersection of the MAL. Laparoscopy is the first step of the hybrid technique combined with percutaneous angioplasty and stenting of the CT. Aim: To demonstrate the usefulness and advantages of the laparoscopic approach in the treatment of Dunbar syndrome. Material and methods : Between 2013 and 2016 in the General and Minimally Invasive Surgery Department of the Medical Sciences Faculty of the University of Warmia and Mazury in Olsztyn, 6 laparoscopic procedures were performed because of median arcuate ligament syndrome. During the laparoscopy the MAL was cut with a harmonic scalpel. One month after laparoscopy 5 patients had Doppler percutaneous angioplasty of the CT with stent implantation in the Vascular Surgery Department in Pomeranian Medical University in Szczecin. Results : In one case, there was a conversion of laparoscopic surgery to open due to unmanageable intraoperative bleeding. In one case, postoperative ultrasound examination of the abdominal cavity demonstrated the presence of a large hematoma in the retroperitoneal space. All patients reported relief of symptoms in the first days after the operation. Conclusions : The hybrid method, combining laparoscopy and angioplasty, seems to be a long-term solution, which increases the comfort of the patient, brings the opportunity for normal functioning and minimizes the risk of restenosis.

2017-01-01

The aim of this study was to evaluate and compare strain around abutment teeth with different attachments used for implant-assisted distal extension partial overdentures (IADEPODs). A mandibular Kennedy class I acrylic model (remaining teeth from first premolar to first premolar) was constructed. A conventional partial denture was constructed over the model (control, group 1). Two laboratory implants were then placed bilaterally in the first molar areas parallel to each other and perpendicular to the residual ridge. Three additional experimental partial overdentures (PODs) were constructed and connected to the implants using ball (group 2), magnetic (group 3), and Locator (group 4) attachments. Three linear strain gauges were bonded buccal, lingual, and distal to the first premolar abutment tooth at the right (loading) and the left (nonloading) sides. For each group, a universal testing device was used to apply a unilateral vertical static load (50 N) on the first molar area, and the strain was recorded using a multichannel digital strainometer. Significant differences between groups and between sites of strain gauges were detected. Strains recorded for all groups were compressive (negative) in nature. Group 1 demonstrated the highest strain, followed by group 3 and group 4; group 2 recorded the lowest strain. For group 2, the highest strain was recoded at the lingual nonloading side. For group 1, group 3, and group 4, the highest strain was recorded at the buccal loading side. Within the limitation of the present study, ball attachments used to retain IADEPODs to the implants were associated with lower strains around abutment teeth than Locator and magnetic attachments. The highest strain was recorded with conventional partial dentures. © 2015 by the American College of Prosthodontists.

Standardization of postoperative care has been shown to decrease postoperative length of stay. In June 2009, we standardized postoperative care for all gastrectomies at our institution. Four years' worth of total gastrectomies (2 years prior to standardization and 2 years after standardization) were reviewed to determine the effect of standardization on postoperative care, length of stay, complications, and readmissions. Between June 2007 and July 2011, 99 patients underwent curative intent open total gastrectomy: 51 patients prior to standardization, and 48 patients poststandardization. Patients were predominantly male (70%); median age was 63; and median body mass index was 26. Standardization of postoperative care was associated with a decrease in median time to beginning both clear liquids and a postgastrectomy diet, earlier removal of epidural catheters, earlier use of oral pain medication, less time receiving intravenous fluids, and decreased length of stay (all P Care Center, or readmission.

2018-03-06

The laparoscopic sleeve gastrectomy is now the most common bariatric operation in the United States and has become an established procedure in the armamentarium of the bariatric surgeon. However, this has happened without the strong support of long-term outcomes data, namely the rate of revision and durability of the weight loss. Newly published data from around the world are starting to show alarming trends in these 2 areas. This paper will examine the published and presented data with at least a 7-year follow-up. This is a meta-analysis on published data with at least 7 years of follow-up from the laparoscopic sleeve gastrectomy. Online published articles. We performed a meta-analysis of publications with at least 7 years of follow-up with the keywords "laparoscopic, bariatric, sleeve gastrectomy, sleeve, long-term, long, term, results, follow-up, follow up, conversion, 7 years, 8 years, 9 years, 10 years, 11 years." We queried the PubMed, MEDLINE, and ClinicalKey search engines, which included abstracts as well. The I 2 statistic was used to determine the heterogeneity across the studies. In presence of heterogeneity, a random effect model using the Dersimonian and Laird method was used to estimate the pooled estimates. The results were summarized using effect size along with a 95% confidence interval (CI). Meta-regression was also used to assess the effect of body mass index and follow-up years on the incidence of recidivism at ≥7 years. Nine cohort studies met the inclusion criteria, with a total of 2280 patients included initially. Only 652 patients had completed ≥7 years of follow-up. At ≥7 years, the long-term weight recidivism rate was estimated to be 27.8% (I 2 = .60%; 95% CI: 22.8%-32.7%) with a range of 14% to 37%. The overall revision rate was estimated to be 19.9% (I 2 = 93.8%; 95% CI: 11.3%-28.5%). This was broken down into 13.1% (I 2 = 93.8%; 95% CI: 5.6%-20.6%) due to weight regain (5 studies) and 2.9% (I 2 = 60.8%; 95% CI: 1%-4.9%) due to

We studied the effects of a splenectomy in combination with immunotherapy on the survival of patients who had undergone a total gastrectomy. It was found that a splenectomy was not effective against advanced gastric cancer at stage III, and that the spleen should be retained for immunotherapy. Splenectomy for gastric cancer at terminal stage IV, particularly in combination with immunotherapy, produced not only augmentation of cellular immunity, but also increased survival.

Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables.One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications.Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP.There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results.

Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers. To determine the association between perioperative morbidity and the number of stapler firings during laparoscopic sleeve gastrectomy. This observational study was based on retrospective analysis of prospectively collected data in patients operated on for morbid obesity in a teaching hospital/tertiary referral center for general surgery. The patients who underwent LSG were analyzed in terms of the number of stapler firings used as a new potential risk predictor for postoperative complications after surgery, adjusting for other patient- and treatment-related factors. The study included 333 patients (209 women, 124 men, mean age: 40 ±11). During the first 30 days after surgery, complications were observed in 18 (5.41%) patients. Multivariate analysis showed that prolonging operative time increased morbidity (every minute, OR = 1.01; 95% CI: 1.00-1.02) and the complication rate increased with the number of stapler firings (every firing, OR = 1.91; 95% CI: 1.09-3.33; p = 0.023). Additional stapler firings above the usual number and a prolonged operation should alert a surgeon and the whole team about increased risk of postoperative complications.

Full Text Available Background and Objective: The optimal treatment strategy for patients with gastric cancer is gastrectomy. Typically, nasogastric intubation is used after this type of surgery to feed patients; however, there seems to be no unanimity of opinion on this topic. Therefore, this study aimed to evaluate the effect of nasogastric intubation on gastrointestinal function after gastrectomy in gastric cancer patients. Materials and Method: This clinical trial was conducted on gastric cancer patients, admitted to the general ward of Imam Reza Hospital in Mashhad, Iran in 2015. In total, 68 patients were selected through randomized convenience sampling and divided into two intervention and control groups of 34 individuals. Nasogastric tube insertion was applied for the intervention group after the surgery. Patients of the study groups were fasted for three days after the surgery, which was followed by the removal of nasogastric tubes and initiation of oral feeding. Gastrointestinal function of all the participants was evaluated six hours after transferring to the ward up to seven days after the surgery on a daily basis using nausea and vomiting assessment tools and researcher-made questionnaire of gastrointestinal function. Data analysis was performed in SPSS version 16 using Fisher’s exact test, Chi-square, Mann-Whitney U, repeated measures ANOVA and paired t-test. Results: In this study, the severity of nausea and vomiting, the first time of passing gas and severity of flatulence Intensity were less observed in the control group, compared to the intervention group. Moreover, postoperative food tolerance was higher in the patients of the control group, compared to the other study group (P<0.05. Conclusion: According to the results of this study, nasogastric intubation can delay normal gastrointestinal function after gastrectomy. Therefore, it is not recommended to use this method after gastrectomy.

Ten years after the first reports of laparoscopic techniques in colorectal surgery the precise role for these approaches in future colorectal practice as still to be defined. However, it seems most unlikely that the application is going to disappear. Laparoscopic colectomy is undoubtedly a complex. time-consuming procedure and it is clear that the technique is intolerant of difficult cases and will likely remain thus. Therefore. the potential advantages of laparoscopy do not as yet appear to be attainable across the board in colorectal resection. Such generalized advantage may, however, be tantalizingly close. Although many studies have failed to show major benefits for laparoscopy in terms of postoperative recovery, it must be remembered that most of these have been of insufficient statistical power to settle the issue. What is clear to all involved in the field is that very many patients do gain major benefit from the minimally invasive approach. The challenge for the future lies in developing the technology to such a point that these benefits for patients are more reproducible. The requirement for a significant abdominal incision to deliver an intact specimen represents a significant hurdle in this regard. The importance of pathological staging for colorectal cancer at present mandates retrieval of an intact specimen. It is of course possible that radiological staging may develop to such a point that surgeons need only remove the lesion with minimal attention to lymphadenectomy. Alternatively, new adjuvant therapies may arrive that, by virtue of increased efficacy and low side-effect profiles, may be applicable to all but the earliest lesions. Finally, increasing health awareness and application of screening programs may lead to a preponderance of large polyps and preinvasive lesions for which a more limited resection may be appropriate. Obviously these scenarios remain almost entirely speculative. However, the trend towards less invasive local therapy for

A 67-year-old male was referred to our otolaryngological clinic because of aphonia and dysphagia. His voice was breathy and he could not even swallow saliva following a total gastrectomy for gastric carcinoma performed 2 weeks previously. Laryngeal fiberscopy revealed major glottal incompetence when he tried to phonate. However, both vocal folds abducted over the full range during inhalation. The patient could not swallow saliva because of a huge glottal chink, even during phonation. Based on these findings, he was diagnosed as having bilateral incomplete cricoarytenoid dislocation after intubation. The patient underwent speech therapy; within 1 min his vocal fold movement recovered dramatically and he was able to phonate and swallow. There have been few case reports of bilateral cricoarytenoid dislocation, and no effective rehabilitation has been reported. We believe that our method of vocal rehabilitation serves as a useful reference for physicians and surgeons worldwide.

Refinements in microsurgery have made distal finger replantation an established technique with high success rates and good functional and aesthetic outcomes. However, it still represents a technically demanding procedure due to the small vessel caliber and frequent lack of vessel length, requiring the use of interpositional venous grafts in some instances. We describe a new technique for anastomosis in fingertip replantation, whereby the need for venous grafts is eliminated. Applying the reverse distal transverse palmar arch technique, 11 cases of distal digital replantation were performed between January 2011 and July 2016. The described procedure was used for arterial anastomosis in 10 cases and arteriovenous shunting for venous drainage in 1 case. A retrospective case review was conducted. The technical description and clinical outcome evaluations are presented. Ten of the 11 replanted digits survived, corresponding to an overall success rate of 91%. One replant failed due to venous insufficiency. Blood transfusions were not required for any of the patients. Follow-up (range, 1.5-5 months) revealed near-normal range of motion and good aesthetic results. All of the replanted digits developed protective sensation. The average length of hospital admission was 5 days. All patients were satisfied with the results and were able to return to their previous work. The use of the reverse distal transverse palmar arch is a novel and reliable technique in distal digital replantation when an increase in vessel length is required, allowing for a tension-free arterial repair without the need for vein grafts.

A 69-year-old man with right upper quadrant abdominal pain and fever was referred to our hospital. He had a history of asbestosis exposure. Computed tomography(CT)revealed a mass at the right subhepatic space, and an antibiotic was administered after a diagnosis of an abdominal abscess. However, the patient did not respond to the treatment, and finally, exploratory laparoscopy was performed. A sheet of combined white nodules surrounding the right lobe of the liver was found, and the mass was continuous with the covering particles. Biopsy of the mass and immunohistochemical examination was performed. The resulting diagnosis was diffuse epithelial malignant peritoneal mesothelioma(MPM). Postoperative systematic chemotherapy of pemetrexed and cisplatin was administered. Laparoscopy was useful to evaluate the distribution of the MPM, which led to adequate therapeutic determination.

Full Text Available Objectives: To investigate the analgesic effect of a subcostal-posterior transversus abdominis plane (TAP block combination following laparoscopic sleeve gastrectomy. Methods: This study was conducted at Fatih Sultan Mehmet Educational and Research Hospital, Istanbul, Turkey, between March 2014 and June 2015. A total of 40 patients with a body mass index of 40-60 kg/m2 scheduled for laparoscopic sleeve gastrectomy were randomly allocated into 2 groups. Patients in Group I (n=20 received a bilateral subcostal TAP block, and patients in Group II (n=20 received a bilateral subcostal and posterior TAP block. Pain intensity was assessed at rest and during coughing using the visual analog scale (VAS prior to and at various time points after TAP block (0 min, 30 min, 2 hours, 4 hours, 6 hours, 12 hours, and 24 hours. Morphine consumption over 24 hours and time to first morphine requirement were recorded. Results: There was no difference in VAS scores between groups. Morphine consumption was 6.78±5.95 mg in Group I, and 7.28±5.95 mg in Group II (p=0.795. Time to first morphine requirement was 267.22±303.84 min for Group I, and 207.80±209.81 min for Group II (p=0.154. Conclusions: Subcostal-posterior TAP block provided equivalent analgesia to subcostal TAP block alone following laparoscopic sleeve gastrectomy.

A significant body weight loss (BWL) is observed during 1 month after gastrectomy for gastric cancer. However, it remains unclear which body component mainly accounts for the weight loss. Two-hundred forty-four patients who underwent gastrectomy for gastric cancer between May 2010 and October 2013 were examined. Body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery (first measurement), at 1 week after surgery (second measurement), and at 1 month after surgery (third measurement). The changes in the early period were defined as the differences until the second measurement, and those in the late period were defined as the differences from the second to the third measurement. Total BWL within 1 month was -3.4 kg, and the rate of body weight at 1 month to the preoperative body weight was 94.1 %. BWL was significantly greater in the early period than in the late period (-2.1 kg vs -1.2 kg, p body mass was significantly greater than loss of fat mass (-1.5 kg vs -0.6 kg, p body mass accounted for a significant part of the BWL during the first week.

Determining the optimal design for surgical skills training is an ongoing research endeavor. In education literature, varied practice is listed as a positive intervention to improve acquisition of knowledge and motor skills. In the current study we tested the effectiveness of a varied practice intervention during laparoscopy training. Twenty-four trainees (control group) without prior experience received a 3 weeks laparoscopic skills training utilizing four basic and one advanced training task. Twenty-eight trainees (experimental group) received the same training with a random training task schedule, more frequent task switching and inverted viewing conditions on the four basic training tasks, but not the advanced task. Results showed inferior performance of the experimental group on the four basic laparoscopy tasks during training, at the end of training and at a 2 months retention session. We assume the inverted viewing conditions have led to the deterioration of learning in the experimental group because no significant differences were found between groups on the only task that had not been practiced under inverted viewing conditions; the advanced laparoscopic task. Potential moderating effects of inter-task similarity, task complexity, and trainee characteristics are discussed.

We present an approach to laparoscopic radical nephrectomy and intact specimen extraction, which incorporates hand assisted and standard laparoscopic techniques. A refined approach to laparoscopic radical nephrectomy is described and our experience is reviewed. A low, muscle splitting Gibson incision is made just lateral to the rectus muscle and the hand port is inserted. A trocar is placed through the hand port and pneumoperitoneum is established. With the laparoscope in the hand port trocar 2 additional trocars are placed under direct vision. The laparoscope is then repositioned through the middle trocar and standard laparoscopic instruments are used through the other 2 trocars including the one in the hand port. If at any time during the procedure the surgeon believes the hand would be useful or needed, the trocar is removed from the hand port and the hand is inserted. This approach has been applied to 7 patients. Mean estimated blood loss was 200 cc (range 50 to 300) and mean operative time was 276.7 minutes (range 247 to 360). Mean specimen weight was 767 gm. (range 538 to 1,170). Pathologically 6 specimens were renal cell carcinoma (grades 2 to 4) and 1 was oncocytoma. Mean length of hospital stay was 3.71 days (range 2 to 7). There were no major complications. We believe that this approach enables the surgeon to incorporate the advantages of the hand assisted and standard laparoscopic approaches.

Reposition and fixation of unstable distal clavicle fractures with a low profile locking plate (Acumed, Hempshire, UK) in conjunction with a button/suture augmentation cerclage (DogBone/FibreTape, Arthrex, Naples, FL, USA). Unstable fractures of the distal clavicle (Jäger and Breitner IIA) in adults. Unstable fractures of the distal clavicle (Jäger and Breitner IV) in children. Distal clavicle fractures (Jäger and Breitner I, IIB or III) with marked dislocation, injury of nerves and vessels, or high functional demand. Patients in poor general condition. Fractures of the distal clavicle (Jäger and Breitner I, IIB or III) without marked dislocation or vertical instability. Local soft-tissue infection. Combination procedure: Initially the lateral part of the clavicle is exposed by a 4 cm skin incision. After reduction of the fracture, stabilization is performed with a low profile locking distal clavicle plate. Using a special guiding device, a transclavicular-transcoracoidal hole is drilled under arthroscopic view. Additional vertical stabilization is arthroscopically achieved by shuttling the DogBone/FibreTape cerclage from the lateral portal cranially through the clavicular plate. The two ends of the FibreTape cerclage are brought cranially via adjacent holes of the locking plate while the DogBone button is placed under the coracoid process. Thus, plate bridging is achieved. Finally reduction is performed and the cerclage is secured by surgical knotting. Use of an arm sling for 6 weeks. Due to the fact that the described technique is a relatively new procedure, long-term results are lacking. In the short term, patients postoperatively report high subjective satisfaction without persistent pain.

Full Text Available Nasogastric tubes (NGTs are important for feeding, stenting and decompression after gastrointestinal surgeries, particularly in the upper gastrointestinal tract. Resistance in the removal of a NGT is a rare surgical complication and may be due to a knot in the tube or a stitch anchoring the tube to an anastomosis. We report a 41-year-old male patient who was admitted to the King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia, in 2015 with stomach cancer. He underwent a radical total gastrectomy with a Roux-en-Y oesophagojejunostomy. One week after the surgery, removal of the NGT was attempted; however, this was very difficult and the proximal end of the tube was cut off as a temporary measure. Six weeks later, an upper gastrointestinal tract endoscopy revealed that the distal end of the NGT had been accidentally stitched to the Roux-en-Y oesophagojejunostomy. The stitch was removed and the rest of the NGT was successfully extracted using a snare.

Objective: To describe the results of laparoscopic procedures at a Urology - Nephrology tertiary care centre. Study Design: Case series / observational study. Place and Duration of Study: The Kidney Centre Postgraduate Training Institute, Karachi, from August 2007 to March 2012. Methodology: Medical records of all planned laparoscopic surgery conducted during the study period were reviewed. Those cases which to open surgery were excluded. All were performed by a single surgeon, initially as supervised and later independently. Data was maintained for demographic data, procedure details, length of hospital stay, and complications including conversion to open surgeries. Data was analyzed through SPSS 17.0. Results: There were 36 planned laparoscopic surgeries in the specified period. Out of 36 cases, 8 were converted to open surgery. Those who underwent laparoscopic surgery include two diagnostic procedures and renal cyst deroofing each, four ureterolithotomy, nineteen simple nephrectomy and one radical nephrectomy. So in total 28 cases were performed on 15 females and 13 males with mean age of 33.01 A +- 10.9 years. The mean operative time was 216 A +- 100 minutes and mean length of hospital stay was as 2.7 A +- 1.04 days. There were 10 complications in 28 cases, majority being Clavien Grade II including 7% (2/28) blood transfusion. Conclusion: There are technical challenges in learning laparoscopy for practicing urologists. Following some learning model in a systematic manner will help surmounting the technical challenges in learning laparoscopy. (author)

Full Text Available Background/Objectives: Vitamin B12 (VB12 deficiency is a common complication after total gastrectomy which may be associated with megaloblastic anemia and potentially irreversible neurologic symptoms. Intramuscular supplementation of VB12 has been considered the standard treatment, although it is associated with high costs and patient discomfort. Patients/Methods: We performed a prospective uncontrolled study (ACTRN12614000107628 in order to evaluate the clinical and laboratory efficacy of long-term oral VB12 supplementation in patients submitted to total gastrectomy. All patients received daily oral VB12 (1 mg/day and were evaluated every 3 months (clinical and laboratory evaluation: hemoglobin, VB12, total iron, ferritin, and folate. Results: A total of 26 patients were included with a mean age of 64 years (29-79. Patients were included with a mean period of 65 months (3-309 after total gastrectomy. At inclusion time, 17/26 patients were under intramuscular VB12, and 9 had not started supplementation yet. There were normal serum VB12 levels in 25/26 patients (mean VB12 serum levels: 657 pg/mL. The mean follow-up period was 20 (8.5-28 months. During follow-up, all patients had normal VB12 levels and there was no need for intramuscular supplementation. The patient with low VB12 levels had an increase to adequate levels, which remained stable. There were no differences with statistical significance among VB12 levels at 6 (867 pg/mL, 12 (1,008 pg/mL, 18 (1,018 pg/mL, and 24 (1,061 pg/mL months. Iron and folate supplementation was necessary in 21 and 7 patients, respectively. Conclusions: Oral VB12 supplementation is effective and safe in patients who underwent total gastrectomy and should be considered the preferential form of supplementation.

Total or proximal gastrectomy is usually performed for early proximal gastric carcinoma, but the optimal type of gastrectomy is still unknown. We evaluated short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy (LsTG) in comparison with laparoscopic total gastrectomy (LTG) and laparoscopic proximal gastrectomy (LPG). We analyzed 113 patients who underwent LsTG (n = 38), LTG (n = 48), or LPG (n = 27) for cStage I gastric cancer located in the upper third of the stomach. Postoperative morbidities, nutritional status including body weight, serum albumin, hemoglobin, the prognostic nutritional index (PNI), and endoscopic findings at 1 year after surgery were compared between LsTG and both LTG and LPG. Operation time and intraoperative blood loss were similar among the three groups. The incidence of postoperative morbidities was lower in LsTG than in LTG. The degree of body weight loss was significantly smaller in LsTG than in LTG at 6 and 12 months. At 12 months, LsTG resulted in better serum albumin and PNI than LPG, and better hemoglobin than LTG. Endoscopic examination demonstrated that one LsTG patient and two LPG patients had reflux esophagitis. Remnant gastritis was observed more frequently in LPG than in LsTG. No LsTG patient had bile reflux, although it was observed in four LPG patients. LsTG with a very small remnant stomach had favorable short-term outcomes and nutritional status compared with LTG and LPG, so it may be a better treatment option for cStage I proximal gastric carcinoma.

Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for weight loss at 5 years in patients with morbid obesity. The Sleeve vs Bypass (SLEEVEPASS) multicenter, multisurgeon, open-label, randomized clinical equivalence trial was conducted from March 2008 until June 2010 in Finland. The trial enrolled 240 morbidly obese patients aged 18 to 60 years, who were randomly assigned to sleeve gastrectomy or gastric bypass with a 5-year follow-up period (last follow-up, October 14, 2015). Laparoscopic sleeve gastrectomy (n = 121) or laparoscopic Roux-en-Y gastric bypass (n = 119). The primary end point was weight loss evaluated by percentage excess weight loss. Prespecified equivalence margins for the clinical significance of weight loss differences between gastric bypass and sleeve gastrectomy were -9% to +9% excess weight loss. Secondary end points included resolution of comorbidities, improvement of quality of life (QOL), all adverse events (overall morbidity), and mortality. Among 240 patients randomized (mean age, 48 [SD, 9] years; mean baseline body mass index, 45.9, [SD, 6.0]; 69.6% women), 80.4% completed the 5-year follow-up. At baseline, 42.1% had type 2 diabetes, 34.6% dyslipidemia, and 70.8% hypertension. The estimated mean percentage excess weight loss at 5 years was 49% (95% CI, 45%-52%) after sleeve gastrectomy and 57% (95% CI, 53%-61%) after gastric bypass (difference, 8.2 percentage units [95% CI, 3.2%-13.2%], higher in the gastric bypass group) and did not meet criteria for equivalence. Complete or partial remission of type 2 diabetes was seen in 37% (n = 15/41) after sleeve gastrectomy and in 45% (n = 18/40) after gastric bypass (P > .99). Medication for dyslipidemia was discontinued in 47% (n�

To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL ± 6.8 before stent insertion, decreased to 4.58 mg/dL ± 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 ± 99 days, and the median patient survival was 179 ± 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

Traumatic injuries to the distal pancreas are infrequent. Universally accepted recommendations about the need for routine splenectomy with distal pancreatectomy do not exist. The aims of this study were to compare outcomes after distal pancreatectomy and splenectomy versus spleen-preserving distal pancreatectomy, and to define the appropriate patient population for splenic preservation. All patients who underwent distal pancreatectomy (January 1, 2007, to December 31, 2014) were identified from the National Trauma Data Bank. Patients with concomitant splenic injury and those who underwent partial splenectomy were excluded. Demographics, clinical data, procedures, and outcomes were collected. Study groups were defined by surgical procedure: distal pancreatectomy and splenectomy versus spleen-preserving distal pancreatectomy. Baseline characteristics between groups were compared with univariate analysis. Multivariate analysis was performed with logistic and linear regression to examine differences in outcomes. Over the 8-year study period, 2,223 patients underwent distal pancreatectomy. After excluding 1,381 patients with concomitant splenic injury (62%) and 8 (pancreatectomy and splenectomy, those who underwent spleen-preserving distal pancreatectomy were younger (p pancreatectomy (p = 0.017). Complications, mortality, and intensive care unit LOS were not significantly different. In young patients after blunt trauma who are not severely injured, a spleen-preserving distal pancreatectomy should be considered to allow for conservation of splenic function and a shorter hospital LOS. In all other patients, the surgeon should not hesitate to remove the spleen with the distal pancreas. Therapy, level IV.

To determine whether immune-enhanced enteral nutrition (EN) was effective on nutritional status, immune function, surgical outcomes and days of hospitalization after total gastrectomy for patients with advanced gastric cancer (AGC). From August 2005 to May 2011, 78 patients with AGC who underwent a total gastrectomy were enrolled and divided randomly into three groups: immune-enhanced EN (EN + glutamine [Gln]) group, standard EN group and control group. Serum parameters including total protein, albumin, proalbumin and transferrin were examined on preoperative day 1, postoperative day 2 and day 12. Levels of immunoglobulin M (IgM), immunoglobulin G (IgG), natural killer (NK) cells, CD4⁺ and CD8⁺ T cells were also compared. The formulas were tolerated well in all the patients except 5 with mild complications. The EN + Gln and EN groups showed a faster onset of flatus and shorter hospitalization duration than the control group. On postoperative day 12, serum total protein, albumin, proalbumin and transferrin levels of the EN + Gln and EN groups were significantly higher than those of the control group (P nutritional status and immune function for the patients with AGC after total gastrectomy. © 2012 The Authors.

Full Text Available Introduction: Oesophageal resection were notoriously complicated and produces a cohort of patients prone to postoperative complications and here we would like to focus on the implementation and effectiveness of early chest tube removal in ERAS after oesophago-gastrectomy considering the various aspect like pleural effusion and reducing the length of hospital stay which ultimately lead to reducing the economic burden on patient. Methods: An ERAS programme was devised and implemented with the support of a dedicated in-hospital task-force. The patients underwent esophago-gastrectomy were randomly divided into two groups: the ERAS group and the control group (non-ERAS. The ERAS group was treated with early removal of the chest tube after surgery, and the control group was treated with traditional way and outcomes were compared between them. Results: The length of hospital stay and the cost of hospitalization in the ERAS group were significantly lower than those in the control group（p<0.05. However, there was no statistical significant difference in the incidences of pleural effusion between the two groups（p＞0.05. Conclusions: The introduction of early chest tube removal as an ERAS programme after oesophago-gastrectomy would not increase the risk of pleural effusion and would not increase the total length of stay and cost of hospitalisation without jeopardising patient safety or clinical outcomes.

Although laparoscopy is becoming the standard of care for the treatment of colorectal disease, its application in case of postoperative peritonitis is still not widespread. The objective of this article is to evaluate the role of laparoscopy in the management of postoperative peritonitis after elective minimally invasive colorectal resection for malignant and benign diseases. Between April 2010 and May 2016, 536 patients received primary minimally invasive colorectal surgery at our Department. Among this series, we carried out a retrospective study of those patients who, having developed signs of peritonitis, were treated with a laparoscopic reintervention. Patient demographics, type of complication and of the main relaparoscopic treatment, and main outcomes of reoperation were recorded. A total of 20 patients (3.7%) underwent relaparoscopy for the management of postoperative peritonitis, of which exact causes were detected by laparoscopy in 75% as follows: anastomotic leakage (n = 8, 40%), colonic ischemia (n = 2, 10%), iatrogenic bowel tear (n = 4, 20%), and other (n = 1, 5%). The median time between operations was 3.5 days (range, 2-8). The laparoscopic reintervention was tailored case by case and ranged from lavage and drainage to redo anastomosis with ostomy fashioning. Conversion rate was 10% and overall morbidity was 50%. No cases required additional surgery and 30-day mortality was nil. Three patients (15%) were admitted to intensive care unit for 24-hour surveillance. Our experience suggests that in experienced hands and in hemodynamically stable patients, a prompt laparoscopic reoperation appears as an accurate diagnostic tool and an effective and safe option for the treatment of postoperative peritonitis after primary colorectal minimally invasive surgery.

Virtual reality (VR) applications with head-mounted displays (HMDs) have had an impact on information and multimedia technologies. The current work aimed to describe the process of developing a highly immersive VR simulation for laparoscopic surgery. We combined a VR laparoscopy simulator (LapSim) and a VR-HMD to create a user-friendly VR simulation scenario. Continuous clinical feedback was an essential aspect of the development process. We created an artificial VR (AVR) scenario by integrating the simulator video output with VR game components of figures and equipment in an operating room. We also created a highly immersive VR surrounding (IVR) by integrating the simulator video output with a [Formula: see text] video of a standard laparoscopy scenario in the department's operating room. Clinical feedback led to optimization of the visualization, synchronization, and resolution of the virtual operating rooms (in both the IVR and the AVR). Preliminary testing results revealed that individuals experienced a high degree of exhilaration and presence, with rare events of motion sickness. The technical performance showed no significant difference compared to that achieved with the standard LapSim. Our results provided a proof of concept for the technical feasibility of an custom highly immersive VR-HMD setup. Future technical research is needed to improve the visualization, immersion, and capability of interacting within the virtual scenario.

The recent scientific and technologic advances have profoundly affected the training of surgeons worldwide. We describe a novel intraoperative real-time training module, the Advanced Robotic Multi-display Educational System (ARMES). We created a real-time training module, which can provide a standardized step by step guidance to robotic distal subtotal gastrectomy with D2 lymphadenectomy procedures, ARMES. The short video clips of 20 key steps in the standardized procedure for robotic gastrectomy were created and integrated with TilePro™ software to delivery on da Vinci Surgical Systems (Intuitive Surgical, Sunnyvale, CA). We successfully performed the robotic distal subtotal gastrectomy with D2 lymphadenectomy for patient with gastric cancer employing this new teaching method without any transfer errors or system failures. Using this technique, the total operative time was 197 min and blood loss was 50 mL and there were no intra- or post-operative complications. Our innovative real-time mentoring module, ARMES, enables standardized, systematic guidance during surgical procedures. © 2017 Wiley Periodicals, Inc.

Minimally invasive procedures for pancreatic pathologies are increasingly being used, including distal pancreatectomy. This study aimed to assess the indications for and outcomes of the da Vinci distal pancreatectomy procedure. We reviewed the medical records of patients who underwent pancreatic head resection from April 2009 to September 2013. Four patients (mean age, 52.7 years) underwent da Vinci distal pancreatectomy and 10 (mean age, 68.0 +/- 12.1 years) underwent laparoscopic distal pancreatectomy. The mean surgical duration was 292 +/- 153 min and 306 +/- 29 min, the mean blood loss was 153 +/- 71 mL and 61.7 +/- 72 mL, and the mean postoperative length of stay was 24 +/- 11 days and 14 +/- 3 days in the da Vinci distal pancreatectomy and laparoscopic distal pancreatectomy groups, respectively. One patient who underwent da Vinci distal pancreatectomy developed a pancreatic fistula, while 2 patients in the laparoscopic distal pancreatectomy group developed splenic ischemia and gastric torsion, respectively. Laparoscopic and robotic pancreatic resection were both safe and feasible in selected patients with distal pancreatic pathologies. Further studies are necessary to clarify the role of robotic surgery in the advanced laparoscopic era.

Background. Laparoscopic sleeve gastrectomy (LSG) has become a popular operation during the recent years. This procedure requires resection of 80-90% of the stomach. Extraction of gastric specimen is known to be a challenging and costly stage of the operation. In this paper, we report results of a simple and cost-effective specimen extraction technique which was applied to 137 consecutive LSG patients. Methods. Between October 2013 and October 2015, 137 laparoscopic sleeve gastrectomy surgeries were performed at Dokuz Eylul University General Surgery Department, Upper Gastrointestinal Surgery Unit. All specimens were extracted through a 15 mm trocar site without using any special device. Results. We noticed one superficial incisional surgical site infection and treated this patient with oral antibiotics. No cases of trocar site hernia were observed. Conclusion. Different techniques have been described for specimen extraction. This simple technique allows extraction of specimen safely in a short time and does not require any special device.

Full Text Available Introduction: In recent years, enhancements in implants have made their use possible as a mode of absolute anchorage in orthodontic patients. In this paper, the authors have introduced an innovative technique to unilaterally distalize the upper left 1 st molar to obtain an ideal Class I molar relationship from a Class II existing molar relationship with an indigenous designed distalizer. Clinical Innovation: For effective unilateral diatalization of molar, a novel cantilever sliding jig assembly was utilized with coil spring supported by a buccally placed single micro implant. The results showed 3 mm of bodily distalization with 1 mm of intrusion and 2° of distal tipping of upper left 1 st molar in 1.5 months. Discussion: This appliance is relatively easy to insert, well-tolerated, and requires minimal patient cooperation compared to other present techniques of molar distalization. Moreover, it is particularly useful in cases that are Class II on one side and Class I on the other, with a minor midline discrepancy and nominal overjet. Patient acceptance level was reported to be within patients physiological and comfort limits.

Breast cancer is the most common malignant neoplasm in the female population. However, stomach is a rare site for metastasis, and can show up many years after initial diagnosis and treatment of the primary tumor. Analyze a case series of this tumor and propose measures that can diagnose it with more precocity. Were analyzed 12 patients with secondary gastric tumors. Immunohistochemistry has demonstrated that primary tumor was breast cancer. We retrieved information of age, histological type, interval between diagnosis of the primary breast cancer and its metastases, immunohistochemistry results, treatment and survival. The mean age was 71.3 years (ranging 40-86). Ten cases had already been underwent mastectomy in the moment of the diagnosis of gastric metastasis. Two patients had diagnosis of both primary and secondary tumors concomitantly. At average, diagnosis of gastric metastasis was seven years after diagnosis of primary breast cancer (ranging 0-13). Besides, nine cases had also metastases in other organs, being bones the most affected ones. Immunohistochemistry of the metastases has shown positivity for CK7 antibody in 83.34%, estrogen receptor in 91.67%, progesterone receptor in 66.67% and AE1AE3 antibody in 75%, considering all 12 cases. Moreover, CK20 was absent significantly (66.67%). The positivity of BRST2 marker did not present statistical significance (41.67%). Eight cases were treated with chemotherapy associated or not with hormonal blockade. Surgical treatment of gastric metastasis was performed in four cases: three of them with total gastrectomy and one with distal gastrectomy. Follow-up has shown a mean survival of 14.58 months after diagnosis of metastasis, with only two patients still alive. Patients with a history of breast cancer presenting endoscopic diagnosis of gastric cancer it is necessary to consider the possibility of gastric metastasis of breast cancer. The confirmation is by immunohistochemistry and gastrectomy should be oriented in

Iatrogenic and spontaneous downstream microembolization of atheromatous material is increasingly recognized as a source of cardiovascular morbidity and mortality. Devising ways of reducing this distal embolization using a variety of mechanical means--distal protection--is currently under intense and diverse investigation. This review therefore summarizes the present status of distal protection. It examines the problem of distal embolization, describes the available distal protection devices, reviews those areas of cardiovascular medicine where distal protection devices are being investigated, and discusses potential future developments.

Minimally invasive surgery requires technical skills distinct from those used in conventional surgery. The aim of this prospective study was to identify personal characteristics that may predict the attainable proficiency level of first-time virtual reality laparoscopy (VRL) trainees. Two hundred and seventy-nine consecutive undergraduate medical students without experience attended a standardized VRL training. Performance data of an abstract and a procedural task were correlated with possible predictive factors providing potential competence in VRL. Median global score requirement status was 86.7% (interquartile range (IQR) 75-93) for the abstract task and 74.4% (IQR 67-88) for the procedural task. Unadjusted analysis showed significant increase in the global score in both tasks for trainees who had a gaming console at home and frequently used it as well as for trainees who felt self-confident to assist in a laparoscopic operation. Multiple logistic regression analysis identified frequency of video gaming (often/frequently vs. rarely/not at all, odds ratio: abstract model 2.1 (95% confidence interval 1.2; 3.6), P = 0.009; virtual reality operation procedure 2.4 (95% confidence interval 1.3; 4.2), P = 0.003) as a predictive factor for VRL performance. Frequency of video gaming is associated with quality of first-time VRL performance. Video game experience may be used as trainee selection criteria for tailored concepts of VRL training programs.

Virtual reality (VR) training simulators have started playing a vital role in enhancing surgical skills, such as hand-eye coordination in laparoscopy, and practicing surgical scenarios that cannot be easily created using physical models. We describe a new VR simulator for basic training in laparoscopy, i.e. SmartSIM, which has been developed using a generic open-source physics engine called the simulation open framework architecture (SOFA). This paper describes the systems perspective of SmartSIM including design details of both hardware and software components, while highlighting the critical design decisions. Some of the distinguishing features of SmartSIM include: (i) an easy-to-fabricate custom-built hardware interface; (ii) use of a generic physics engine to facilitate wider accessibility of our work and flexibility in terms of using various graphical modelling algorithms and their implementations; and (iii) an intelligent and smart evaluation mechanism that facilitates unsupervised and independent learning.

In adults undergoing gastric bypass surgery, it is routine practice to perform pre-operative testing for Helicobacter pylori infection. Evidence suggests that infection impairs anastomotic healing and contributes to complications. There currently are no data for adolescents undergoing bariatric procedures. Despite few patients with pre-operative symptoms, we noted occasional patients with H. pylori detected after sleeve gastrectomy. We reviewed our experience with our adolescent sleeve gastrectomy cohort to determine the prevalence of H. pylori infection, its predictive factors, and association with outcomes. We hypothesized that H. pylori infection would be associated with pre-operative symptoms, but not surgical outcomes. All patients undergoing sleeve gastrectomy at our hospital were included. We conducted a chart review to determine pre- or post-operative symptoms of gastroesophageal reflux disease GERD or gastritis, operative complications, and long-term anti-reflux therapy after surgery. Pathology reports were reviewed for evidence of gastritis and H. pylori infection. 78 adolescents had laparoscopic sleeve gastrectomy from January 2010 through July 2014. The prevalence of chronic gastritis was 44.9% (35/78) and 11.4% of those patients had H. pylori (4/35). Only one patient with H. pylori had pre-operative symptoms, and only 25.7% (9/35) of patients with pathology-proven gastritis had symptoms. One staple line leak occurred but this patient did not have H. pylori or gastritis. Mean patient follow-up was 10 (3-26) mos. There is a moderate prevalence of gastritis among adolescents undergoing sleeve gastrectomy, but only a small number of these patients had H. pylori infection. Neither the presence of chronic gastritis nor H. pylori infection correlated with symptoms or outcomes. Thus, in the absence of predictive symptomology or adverse outcome in those who are infected, we advocate for continued routine pathologic evaluation without the required need for pre

To assess the effectiveness of the new anterolateral approach of the distal femur for the treatment of distal femoral fractures. Between July 2007 and December 2009, 58 patients with distal femoral fractures were treated by new anterolateral approach of the distal femur in 28 patients (new approach group) and by conventional approach in 30 patients (conventional approach group). There was no significant difference in gender, age, cause of injury, affected side, type of fracture, disease duration, complication, or preoperative intervention (P > 0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, hospitalization days, and Hospital for Special Surgery (HSS) score of knee were recorded. Operation was successfully completed in all patients of 2 groups, and healing of incision by first intention was obtained; no vascular and nerves injuries occurred. The operation time and intraoperative fluoroscopy frequency of new approach group were significantly less than those of conventional approach group (P 0.05). All patients were followed up 12-36 months (mean, 19.8 months). Bone union was shown on X-ray films; the fracture healing time was (12.62 +/- 2.34) weeks in the new approach group and was (13.78 +/- 1.94) weeks in the conventional approach group, showing no significant difference (t=2.78, P=0.10). The knee HSS score at last follow-up was 94.4 +/- 4.2 in the new approach group, and was 89.2 +/- 6.0 in the conventional approach group, showing significant difference between 2 groups (t=3.85, P=0.00). New anterolateral approach of the distal femur for distal femoral fractures has the advantages of exposure plenitude, minimal tissue trauma, and early function rehabilitation training so as to enhance the function recovery of knee joint.

Minilaparoscopy-assisted transumbilical laparoscopic cholecystectomy

GERALDO JOSÉ DE SOUZA LIMA

Full Text Available ABSTRACT The role of laparoscopy in the modern surgery era is well established. With the prospect of being able to improve the already privileged current situation, new alternatives have been proposed, such as natural orifice endoscopic surgery (NOTES, the method for single transumbilical access (LESS - Laparo-endoscopic single-site surgery and minilaparoscopy (MINI. The technique proposed by the authors uses a laparoscope with an operative channel like the flexible endoscope used in NOTES. All operative times are carried out through the umbilical trocar as in LESS, and assisted by a minilaparoscopy grasper. This new technic combines, and results from, the rationalization of technical particularities and synergy of these three approaches, seeking to join their advantages and minimize their disadvantages.

AIM: To evaluate the prevalence and predictive factors of osteoporosis in patients with gastric adenocarcinoma after gastrectomy.METHODS: The study included 133 patients diagnosed with gastric adenocarcinoma but who did not undergo prior diagnostic work-up for osteoporosis. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA) and vertebral deformity was assessed by plain X-rays. We evaluated the effects of age, sex, body mass index (BMI), anemia, back pain,vertebral deformity, tumor staging, reconstruction type,and past medical history to determine predictive factors of osteoporosis in these patients.RESULTS: The prevalence of osteoporosis in the lumbar spine was 38.3% (male, 28.9%; female, 54.0%), and 15.0% in the femoral neck (male, 10.8%; female,22.0%). The vertebral deformity rate was 46.6% (male,43.4%; female, 52.0%). Age, BMI and hemoglobin correlated with BMD (P ＜ 0.01). In males, anemia and age ＞ 64 years were independent predictive factors of osteoporosis in multivariate analysis. In females, back pain was an independent factor for osteoporosis.CONCLUSION: The results of this study revealed that prevalence of osteoporosis and vertebral bone deformity rate were high in gastric cancer patients, regardless of post-gastrectomy duration and operation type. Early diagnosis and a proper management plan must be established in these patients.

Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate

Malignancy is a secondary cause of sarcopenia, which is associated with impaired cancer treatment outcomes. The aim of this study was to investigate the prevalence of preoperative sarcopenia among elderly gastric cancer patients undergoing gastrectomy and the differences in preoperative dietary intake and postoperative complications between sarcopenic and non-sarcopenic patients. Ninety-nine patients over 65 years of age who underwent gastrectomy for gastric cancer were analyzed. All patients underwent gait and handgrip strength testing, and whole-body skeletal muscle mass was measured using a bioimpedance analysis technique based on the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm for the evaluation of sarcopenia before surgery. Preoperative dietary intake was assessed using a food frequency questionnaire. Of these patients, 21 (21.2 %) were diagnosed with sarcopenia. Sarcopenic patients consumed fewer calories and less protein preoperatively (23.9 vs. 27.8 kcal/kg ideal weight/day and 0.86 vs. 1.04 g/kg ideal weight/day; P = 0.001 and 0.0005, respectively). Although the overall incidence of postoperative complications was similar in the two groups (57.1 % vs. 35.9 %; P = 0.08), the incidence of severe (Clavien-Dindo grade ≥ IIIa) complications was significantly higher in the sarcopenic group than in the non-sarcopenic group (28.6 % vs. 9.0 %; P = 0.029). In the multivariate analysis, sarcopenia alone was identified as a risk factor for severe postoperative complications (odds ratio, 4.76; 95 % confidence interval, 1.03-24.30; P = 0.046). Preoperative sarcopenia as defined by the EWGSOP algorithm is a risk factor for severe postoperative complications in elderly gastric cancer patients undergoing gastrectomy.

Virtual reality (VR) simulators for surgical training might possess the properties needed for basic training in laparoscopy. Evidence for training efficacy of VR has been investigated by research of varying quality over the past decade. To review randomized controlled trials regarding VR training efficacy compared with traditional or no training, with outcome measured as surgical performance in humans or animals. In June 2011 Medline, Embase, the Cochrane Central Register of Controlled Trials, Web of Science and Google Scholar were searched using the following medical subject headings (MeSh) terms: Laparoscopy/standards, Computing methodologies, Programmed instruction, Surgical procedures, Operative, and the following free text terms: Virtual real* OR simulat* AND Laparoscop* OR train* Controlled trials. All randomized controlled trials investigating the effect of VR training in laparoscopy, with outcome measured as surgical performance. A total of 98 studies were screened, 26 selected and 12 included, with a total of 241 participants. Operation time was reduced by 17-50% by VR training, depending on simulator type and training principles. Proficiency-based training appeared superior to training based on fixed time or fixed numbers of repetition. Simulators offering training for complete operative procedures came out as more efficient than simulators offering only basic skills training. Skills in laparoscopic surgery can be increased by proficiency-based procedural VR simulator training. There is substantial evidence (grade IA - IIB) to support the use of VR simulators in laparoscopic training. © 2012 The Authors  Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

Obesity is one of the most rapidly increasing health problems in children. Laparoscopic sleeve gastrectomy (LSG) is one of the best treatment options and is feasible and safe in children. The aim of this study was to present the short-term results of a laparoscopic sleeve gastrectomy series in children. Children who underwent LSG in 2014-2017 were included in the study. Charts were investigated retrospectively and short-term weight loss was analyzed. Patients who had surgery in 2014-2017 were included in the study. There were six girls and two boys, and the median age was 15 years (range, 11-18 years). Mean weight was 159.25 ± 19.78 kg, and mean body mass index was 61.05 ± 8.5 kg/m 2 . Mean operation time was 70 min (range, 65-90 min), mean hospital stay was 5.1 days (range, 3-7 days), and mean follow up was 19.2 months (range, 1-43 months). Of these patients, five had hypertension and were under medication and two of these five also had hyperinsulinemia. One of the five children had Bardet-Biedl syndrome and one had bronchial asthma. After operation, medication was stopped in four of the eight children. At the time of writing, six patients were doing well without postoperative complications, or the need for reoperation. Even though the follow-up period was short and the number of patients was small, LSG was a feasible and promising surgical method for morbidly obese children. A multidisciplinary approach and lifelong behavior therapy are key steps for success. © 2018 Japan Pediatric Society.

Diagnostic Laparoscopy as Decision Tool for Re-recurrent Inguinal Hernia Treatment Following Open Anterior and Laparo-Endoscopic Posterior Repair

Directory of Open Access Journals (Sweden)

Ferdinand Köckerling

2017-05-01

Full Text Available IntroductionThe guidelines of the international hernia societies recommend posterior repair in laparo-endoscopic technique for recurrent inguinal hernia after open anterior mesh repair and, conversely, open anterior repair for recurrence after laparo-endoscopic primary repair. Even when these guidelines are followed, already 1 year after repair a re-recurrence rate of 1–2% must be expected, with that rate rising further in the subsequent years. Accordingly, increasingly more patients with re-recurrence after anterior and posterior mesh implantation must be treated, which constitutes a problem that to date has been investigated in only very few studies. Hence, there are no well-founded recommendations. This paper now presents a number of case reports aimed at identifying the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment.Patients and methodsBased on three case reports the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment is presented below.ResultsIn all the three cases described explorative laparoscopy played a key role as decision tool when deciding how best to treat re-recurrence after anterior and posterior inguinal hernia repair. In one case severe adhesions after robotic prostatectomy and in another case correct placement of the mesh in the posterior plane, adhesions from the cecum to the groin region and no definitive finding of a re-recurrence resulted in an open repair. In the third case, an insufficient laparoscopic posterior mesh placement made the re-recurrent TAPP procedure relatively easy.ConclusionExplorative laparoscopy is an important decision tool for re-recurrent inguinal hernia treatment to minimize the risks of the procedure for the patients.

The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m 2 (range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m 2 (range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.

This study was undertaken to determine the quality of information on the Internet regarding laparoscopy. Four popular World Wide Web search engines were used with the key word "laparoscopy." Advertisements, patient- or physician-directed information, and controversial material were noted. A total of 14,030 Web pages were found, but only 104 were unique Web sites. The majority of the sites were duplicate pages, subpages within a main Web page, or dead links. Twenty-eight of the 104 pages had a medical product for sale, 26 were patient-directed, 23 were written by a physician or group of physicians, and six represented corporations. The remaining 21 were "miscellaneous." The 46 pages containing educational material were critically reviewed. At least one of the senior authors found that 32 of the pages contained controversial or misleading statements. All of the three senior authors (LKN, NAO, GAF) independently agreed that 17 of the 46 pages contained controversial information. The World Wide Web is not a reliable source for patient or physician information about laparoscopy. Authenticating medical information on the World Wide Web is a difficult task, and no government or surgical society has taken the lead in regulating what is presented as fact on the World Wide Web.

Laparoscopy is beneficial to patients as measured by less painful recovery and an earlier return to functional health compared to conventional open surgery. However, laparoscopy requires the manipulation of long, slender tools from outside the patient's body. As a result, laparoscopy generally benefits only patients undergoing relatively simple procedures. An innovative approach to laparoscopy uses miniature in vivo robots that fit entirely inside the abdominal cavity. Our previous work demonstrated that a mobile, wireless robot platform can be successfully operated inside the abdominal cavity with different payloads (biopsy, camera, and physiological sensors). We hope that these robots are a step toward reducing the invasiveness of laparoscopy. The current study presents design details and results of laboratory and in vivo demonstrations of several new payload designs (clamping, cautery, and liquid delivery). Laboratory and in vivo cooperation demonstrations between multiple robots are also presented.

Objective: To investigate the outcomes of laparoscopic sleeve gastrectomy (LSG) in terms of weight loss. Study Design: Descriptive cohort study. Place and Duration of Study: Department of Surgery, Shifa International Hospital, Islamabad, from January 2009 to January 2015. Methodology: A total of 100 consecutive patients were included in the study through retrospective chart review. A 5-port technique was utilized with the gastric sleeve being created using endostapler. Postoperatively, patients gradually progressed from clear liquid diet and oral rehydration salts to nutritional supplements over three days. By two weeks postoperatively, patients had progressed to a solid diet. SPSS was used for data entry and analysis. Body mass index (BMI) and weight in kg were determined. Results: From 100 patients, 17 were lost to follow-up less than a week into the postoperative period. Of the remaining, average age of the patients was 34.7 ±11.3 years at the time of surgery. The majority of patients were females (72 percentage). Mean preoperative and postoperative BMI was 45.3 ±10.4 kg/m2 and 35.0 ±10 kg/m2, respectively. Of the 83 patients, 62 were followed-up for longer than 1 month (average 419 days). For patients in this category, mean reduction in BMI was 10.3 ±6.5 kg/m2 with average weight loss of 34.3 ±18.2 kg. There were no mortalities associated with LSG. Conclusion: Laparoscopic sleeve gastrectomy is a safe and effective intervention in young Pakistani females with encouraging outcomes at a mean follow-up of over one year. (author)

To determine the feasibility of esophagogastric anastomosis in esophageal cancer radical resection under thoracoscopy combined with laparoscopy in terms of complications and operation time. Experimental study. Department of Thoracic Surgery, Affiliated with The First Hospital, Suzhou University, from June 2008 to June 2012. Clinical data of 136 patients operated for esophageal cancer by radical resection under thoracoscopy combined with laparoscopy was analyzed. Eighty one superior and middle segment esophageal carcinoma patients were operated through right thoracoscope, abdominoscope, and neck incision. The esophagogastric anastomosis was completed in the left side of neck by handiwork. Fifty five inferior segment esophageal carcinoma were operated through right thoracoscope, abdominoscope and the esophagogastric anastomosis was completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus. The operation time and the intra-operative blood loss in patients with intrathoracic mechanical anastomosis was significantly lower than that of cervical anastomosis. Other variables were not significantly different. The practicability of this method of anastomosis that completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus had been well confirmed.

Standard treatment of advanced ovarian cancer is surgery and chemotherapy. The goal of surgery is to remove all macroscopic tumour, as the amount of residual tumour is the most important prognostic factor for survival. When removal off all tumour is considered not feasible, neoadjuvant chemotherapy (NACT) in combination with interval debulking surgery (IDS) is performed. Current methods of staging are not always accurate in predicting surgical outcome, since approximately 40% of patients will have more than 1 cm residual tumour after primary debulking surgery (PDS). In this study we aim to assess whether adding laparoscopy to the diagnostic work-up of patients suspected of advanced ovarian carcinoma may prevent unsuccessful primary debulking surgery for ovarian cancer. Multicentre randomized controlled trial, including all gynaecologic oncologic centres in the Netherlands and their affiliated hospitals. Patients are eligible when they are planned for PDS after conventional staging. Participants are randomized between direct PDS or additional diagnostic laparoscopy. Depending on the result of laparoscopy patients are treated by PDS within three weeks, followed by six courses of platinum based chemotherapy or with NACT and IDS 3-4 weeks after three courses of chemotherapy, followed by another three courses of chemotherapy. Primary outcome measure is the proportion of PDS's leaving more than one centimetre tumour residual in each arm. In total 200 patients will be randomized. Data will be analysed according to intention to treat. Patients who have disease considered to be resectable to less than one centimetre should undergo PDS to improve prognosis. However, there is a need for better diagnostic procedures because the current number of debulking surgeries leaving more than one centimetre residual tumour is still high. Laparoscopy before starting treatment for ovarian cancer can be an additional diagnostic tool to predict the outcome of PDS. Despite the absence

Hydronephrosis is a common disease in children and may be caused by ureteral fibroepithelial polyps (UFP). Ureteral fibroepithelial polyps are rare in children and are difficult to precisely diagnose before surgery. Surgical treatment for symptomatic UFP is recommended. At the present institution, retroperitoneal laparoscopy has been used to treat five boys with UFP since 2006. To highlight the significance of UFP as an etiological factor of hydronephrosis in children and evaluate the applicative value of retroperitoneal laparoscopy in the treatment of children with UFP. Between 2006 and 2013 five boys underwent retroperitoneal laparoscopy at the present institution. They were identified with UFP by review of the clinical database. Detailed data were collected, including: radiographic studies, gross anatomical pathology, and pathology and radiology reports. All boys had been followed up at least every 6 months. All of the boys were aged between 7 and 16 years (mean 9.8 years). The main symptoms were flank pain (all five) and hematuria (three). Radiographic examination showed that all of the boys presented with incomplete ureteral obstruction and hydronephrosis. The ureteral fibroepithelial polyps were located near the left UPJ or the left proximal ureter. All of the boys had the UFP removed: three underwent retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty and polypectomy, and two had retroperitoneal laparoscopic ureteral anastomosis. These polyps were all on the left side and between 15 and 35 mm in length (mean 22 mm) (Figure). All of the boys recovered well and were discharged from hospital. The postoperative histological report confirmed that the specimens were UFP. Hydronephrosis was periodically assessed by ultrasonography (using the same method as pre-surgical ultrasonography) after surgery. Mean follow-up was 33 months (range 6-58 months) and no complications were found afterwards. Ureteral fibroepithelial polyps are rare but rather

To study the accuracy of four-dimensional (4D) ultrasound and power Doppler flow mapping in detecting tubal patency in women with sub-/infertility, and compare it with laparoscopy and chromopertubation. A prospective study. The study was performed in the outpatient clinic and infertility unit of a university hospital. The sonographic team and laparoscopic team were blinded to the results of each other. Women aged younger than 43 years seeking medical advice due to primary or secondary infertility and who planned to have a diagnostic laparoscopy performed, were recruited to the study after signing an informed consent. All of the recruited patients had power Doppler flow mapping and 4D hysterosalpingo-sonography by injecting sterile saline into the fallopian tubes 1 day before surgery. Registering Doppler signals, while using power Doppler, both at the tubal ostia and fimbrial end and the ability to demonstrate the course of the tube especially the isthmus and fimbrial end, while using 4D mode, was considered a patent tube. Out of 50 recruited patients, 33 women had bilateral patent tubes and five had unilateral patent tubes as shown by chromopertubation during diagnostic laparoscopy. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for two-dimensional power Doppler hysterosalpingography were 94.4%, 100%, 100%, 89.2%, and 96.2%, respectively and for 4D ultrasound were 70.4%, 100%, 100%, 70.4%, and 82.6%, respectively. Four-dimensional saline hysterosalpingography has acceptable accuracy in detecting tubal patency, but is surpassed by power Doppler saline hysterosalpingography. Power Doppler saline hysterosalpingography could be incorporated into the routine sub-/infertility workup. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Currently, there is no optimal digestive tract reconstruction technique well recognized by scholars after total gastrectomy. In this study, a new reconstruction method, which is modified from the classic Roux-en-Y procedure, an uncut jejunal esophageal anastomosis with double jejunal pouch (UJEA-DJP) was established, and its advantages for improving the quality of life of patients who undergo total gastrectomy were analyzed. Altogether 160 patients with gastric cancer enrolled in our center from September 2009 to March 2012 received radical D2 total gastrectomy. According to the reconstruction methods used, these patients were divided into three groups: UJEA-DJP (n = 63), Roux-en-Y (n = 45), and P-loop with Roux-en-Y esophagojejunostomy (P-RY; n = 52). The operation time for reconstruction, complications, prognostic nutritional index (PNI), and the Visick classification among the three groups were analyzed. We found that UJEA-DJP has advantages over Roux-en-Y and P-RY regarding the time of digestive tract reconstruction, incidence rates for long-term complications, postoperative nutritional index, body weight recovery, and the Visick classification for subjective feelings (p quality of life of patients after surgical procedure.

The advent of three-dimensional passive stereoscopic imaging has led to the development of 3D laparoscopy. In simulation tasks, a reduction in error rate and performance time is seen with 3D compared to two-dimensional (2D) laparoscopy with both novice and expert surgeons. Robotics utilises 3D and instrument articulation through a console interface. Robotic trials have demonstrated that tasks performed in 3D produced fewer errors and quicker performance times compared with those in 2D. It was therefore perceived that the main advantage of robotic surgery was in fact 3D. Our aim was to compare 3D straight-stick laparoscopic task performance (3D) with robotic 3D (Robot), to determine whether robotic surgery confers additional benefit over and above 3D visualisation. We randomised 20 novice surgeons to perform four validated surgical tasks, either with straight-stick 3D laparoscopy followed by 3D robotic surgery or in the reverse order. The trial was conducted in two fully functional operating theatres. The primary outcome of the study was the error rate as defined for each task, and the secondary outcome was the time taken to complete each task. The participants were asked to perform the tasks as quickly and as accurately as possible. Data were analysed using SPSS version 21. The median error rate for completion of all four tasks with the robot was 2.75 and 5.25 for 3D with a P value performance time for completion of all four tasks with the robot was 157.1 and 342.5 s for 3D with a P value 3D robotic systems over 3D straight-stick laparoscopy, in terms of reduced error rate and quicker task performance time.

This study investigated the effects of acupuncture combined with general anesthesia on postoperative immune and cognitive functions in elderly patients undergoing subtotal gastrectomy. We recruited 96 elderly patients who received anesthesia for subtotal gastrectomy and randomly divided them into control (n=48) and experimental (n=48) groups. The control group received general anesthesia and the experimental group received combined acupuncture and general anesthesia. We measured hemodynamic immediately before and after anesthesia induction, and immune observations before and after surgery. We found no significant differences in mean heart rate (HR), mean oxygen saturation (SpO2), and partial pressure of end-tidal carbon dioxide (PETCO2) in the perioperative period between the two groups. Mean arterial pressure (MAP) was lower in the experimental group than that in the control group (P0.05), but the incidence of delayed recovery and postoperative agitation were significantly lower in the experimental group compared with those in the control group (P<0.05). One day after surgery, the experimental group showed better protection of cognitive function than the control group (P<0.05). Overall, combined acupuncture and general anesthesia in elderly gastric cancer patients receiving subtotal gastrectomy showed more stable hemodynamics and fewer stress responses during surgery. Thus, combined acupuncture and general anesthesia can shorten the recovery time from anesthesia, have less negative effects on immune function and decrease the incidence of postoperative cognitive impairment.

This study was designed to evaluate the efficacy and safety of computed tomography (CT)-guided drainage in treating infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity. From January 2007 to June 2009, 21 patients (9 men and 12 women; mean age, 39.2 (range, 26–52) years) with infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity underwent image-guided percutaneous drainage. All procedures were performed using CT guidance and 8- to 12-Fr pigtail drainage catheters. Immediate technical success was achieved in all 21 infected collections. In 18 of 21 collections, we obtained progressive shrinkage of the collection with consequent clinical success (success rate 86%). In three cases, the abdominal fluid collection was not resolved, and the patients were reoperated. Among the 18 patients who avoided surgery, 2 needed replacement of the catheter due to obstruction. No major complications occurred during the procedure. The results of our study support that CT-guided percutaneous drainage is an effective and safe method to treat infected abdominal fluid collections due to gastric leak in patients who had previously underwent laparoscopic sleeve gastrectomy for morbid obesity. It may be considered both as a preparatory step for surgery and a valuable alternative to open surgery. Failure of the procedure does not, however, preclude a subsequent surgical operation.

Esophagojejunostomy after total gastrectomy still remains a high risk anastomosis with a considerable morbidity and mortality. The majority of these anastomoses are performed by the intraluminal stapler technique, yet stenoses are a known late complication even after an uneventful postoperative course. In the present study, the osophagojejunostomy with the biofragmentable anastomosis ring (BAR) was examined in dogs. 28 dogs were randomized into a group of manual suture (n = 14) and a BAR-group (n = 14). After gastrectomy, the esophagojejunostomy was performed by hand-suture with polypropylene 4-0 in the manual suture group, and with the 25/1.5 mm BAR in the BAR-group. In both groups the Roux-en-Y jejunojejunostomy was performed by hand-suture. The dogs were evaluated on postoperative days 4, 7 and 14 with regard to macroscopy, bursting strength, tissue hydroxyproline and histology. There was one leakage without clinical effect in the hand-sewn group on postoperative day 4; there was no leak in the BAR-group. In observing fibre-free enteral feeding, neither functional disorders nor obstruction of the BAR were observed. The general anastomosis parameters were matchable between the groups. The infracarinal BAR-esophagojejunostomy is comparable to the hand-sewn anastomosis in the dog-model.

Full Text Available Objective: The aim of this study was to demonstrate a lurking ligament and its various formation types and to mention the importance of this ligament in Laparoscopic sleeve gastrectomy Methods: One hundred and twelve patients had laparoscopic sleeve gastrectomy (LSG procedure in our clinic between March 2011 and September 2013. All procedures were performed with a standard operative technique. Only difference for the last 50 patients was to avoid the excessive dissection of posterior gastric wall. The existence of posterior gastric ligament was recorded and different types of posterior gastric ligament was demonstrated. Results: Posterior gastric ligament was observed in all of the cases in different formation types. Three types of ligament; complete, partial and skippy, was demonstrated. 53(47.3% of the patients had skippy, while 41 (36.6% had partial and 18 (16.1% had complete type of posterior gastric ligament. Conclusion: A ligament named as ‘posterior gastric ligament’ and its various forms were defined in the third dimensional plane of stomach. Posterior gastric ligament remains as the only structure in LSG for preventing the mobility and ability of the stomach to rotate. The excessive dissection of the posterior gastric ligament should be avoided to prevent complications such as kinking and volvulus

Laparoscopy andor laparotomy had been performed in 91 patients also examined by hysterosalpingography (HSG) during two years. The comparison of the radiological and the operative findings shows, that total occlusion and hydrosalpinx are radiological signs of adhesions in the pelvis. A depot of contrast medium remaining around the fimbriated end of the oviduct is also a sign of adhesions. More than half of the patients with adhesions surrounding the oviducts and/or endometriosis had however normal hysterosalpingograms. Thus, the radiological examination, hysterosalpingography, has a low sensitivity rate concerning pelvic abnormalities. (orig.) [de

Full Text Available ABSTRACT OBJECTIVE: To measure the quality of life and clinical-functional results from patients diagnosed with osteoarthrosis of the distal radioulnar joint who underwent surgical treatment using the technique of total arthroplasty of the ulna, with a total or partial Ascension(r prosthesis of the distal ulna. METHODS: Ten patients were evaluated after 12 months of follow-up subsequent to total or partial arthroplasty of the distal ulna. All of them presented post-traumatic osteoarthrosis and/or chronic symptomatic instability of the distal radioulnar joint. The study was prospective. Seven patients had previously undergone wrist procedures (two cases with Darrach, three with Sauvé-Kapandji and two with ligament reconstruction of the fibrocartilage complex and three presented fractures of the distal ulna that evolved with pain, instability and osteoarthrosis of the distal radioulnar joint. The following were assessed: quality of life (DASH scale; percentage degree of palm grip strength (kgf and pronosupination range of motion in relation to the unaffected side; pain (VAS; return to work; subjective evaluation of radiography; and complications. RESULTS: The patients presented a mean range of motion of 174.5° (normal side: 180°. Quality of life was analyzed by applying the DASH questionnaire and the mean value found was 5.9. The mean pain score using the VAS was 2.3. The mean degree of palm grip strength (kgf was 50.7, which represented 90.7% of the strength on the unaffected side. The complication rate was 10%: this patient presented slight dorsal instability of the ulna and persistent pain, and did not return to work. This patient is still being followed up in the outpatient clinic and occupational therapy sector, with little improvement. He does not wish to undergo a new procedure. The mean length of follow-up was 16.8 months, with a minimum of 10 and maximum of 36 months. CONCLUSION: This concept is subject to the test of time

Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay. Moreover, new technologies, such as intraoperative fluorescence guidance and augmented reality will define additional indications for robot-assisted pancreatic surgery.

The standard of care for managing pancreaticobiliary disease in altered Roux-en-Y gastric bypass patients is laparoscopy-assisted endoscopic retrograde cholangiopancreatography (LA-ERCP), but is limited by cost and adverse events. Recently a minimally invasive, completely endoscopic approach using endoscopic ultrasound (EUS) directed transgastric ERCP (EDGE) has been described. We aim to compare EDGE to LA-ERCP in this study. Patients from May 2005 to June 2017 with Roux-en-Y gastric bypass anatomy having undergone LA-ERCP or EDGE at 4 tertiary centers were captured in a registry. Patient demographics, procedural details, and clinical outcomes were measured for each group. Seventy-two patients (n=29 EDGE, n=43 LA-ERCP) were included in this study. There was no significant difference in the technical success of EDGE gastrogastric fistula (96.5%) versus LA-gastrostomy creation (100%). The success rate of achieving therapeutic ERCP (EDGE 96.5% vs. LA-ERCP 97.7%) and number of ERCP (EDGE 1.2 vs. LA-ERCP 1.02) needed to achieve clinical resolution was similar between both groups. Adverse event rate for EDGE, 24% (7/29) and LA-ERCP, 19% (8/43) was similar. The total procedure time (73 vs. 184 min) and length of hospital stay (0.8 vs. 2.65 d) was significantly shorter for EDGE compared to LA-ERCP. The overall weight change after EDGE was -6.6 lbs at an average 28-week follow-up. This study suggests that the EDGE procedure has similar technical success and adverse events compared with LA-ERCP with the benefit of significantly shorter procedure times and hospital stay. EDGE may offer a minimally invasive, effective option, with less resource utilization, and without significant weight gain.

Objective: To determine the feasibility of esophagogastric anastomosis in esophageal cancer radical resection under thoracoscopy combined with laparoscopy in terms of complications and operation time. Study Design: Experimental study. Place and Duration of Study: Department of Thoracic Surgery, Affiliated with The First Hospital, Suzhou University, from June 2008 to June 2012. Methodology: Clinical data of 136 patients operated for esophageal cancer by radical resection under thoracoscopy combined with laparoscopy was analyzed. Eighty one superior and middle segment esophageal carcinoma patients were operated through right thoracoscope, abdominoscope, and neck incision. The esophagogastric anastomosis was completed in the left side of neck by handiwork. Fifty five inferior segment esophageal carcinoma were operated through right thoracoscope, abdominoscope and the esophagogastric anastomosis was completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus. Results: The operation time and the intra-operative blood loss in patients with intrathoracic mechanical anastomosis was significantly lower than that of cervical anastomosis. Other variables were not significantly different. Conclusion: The practicability of this method of anastomosis that completed with stapler in right thoracic cavity through superior belly incision and diaphragmatic hiatus had been well confirmed.

Objective: To evaluate the application value of carbon lymph node tracing technique by preoperative endoscopic subserosal injection in laparoscopic radical gastrectomy. Methods: From June 2013 to February 2015, seventy eight patients with gastric cancer were enrolled and randomly divided into trial group and control group. Subserosal injection of carbon nanoparticles around the tumor was performed by preoperative endoscopic subserosal injection one day before the operation in trial group, while the patients routinely underwent laparoscopic gastrectomy in control group. Results of harvested lymph nodes, postoperative complications were compared between the two groups. Carbon nanoparticle-related side effect was also evaluated. Results: The average number of harvested lymph node in trial group was significantly higher than that in control group (35.5±8.5 vs 29.5±6.5, P 0.05), and no carbon nanoparticle-related side effect was observed. Conclusion: Given a higher harvested lymph node number and a similar rate of complications, preoperative endoscopic subserosal injection of carbon nanoparticles was safe and feasible.

The malignant form of atrophic papulosis (Köhlmeier-Degos disease) is a rare thrombo-occlusive vasculopathy that can affect multiple organ systems. Patients typically present with distinctive skin lesions reflective of vascular drop out. The small bowel is the most common internal organ involved, resulting in considerable morbidity and mortality attributable to ischemic microperforations. Determination of the presence of gastrointestinal lesions is critical in distinguishing systemic from the benign, cutaneous only disease and in identifying candidates for treatment. We describe an 18 year old male who first presented with cutaneous atrophic papulosis but became critically ill from small bowel microperforations. He had an almost immediate and dramatic response to treatment. Prior to his presentation with acute abdomen he had upper and lower endoscopy showing areas of nonspecific patchy erythema. At laparotomy, innumerable characteristic lesions with central pearly hue and erythematous border were seen. PubMed was used for a literature search using the keywords malignant atrophic papulosis, Degos disease, endoscopy, laparoscopy and laparotomy. This search yielded 200 articles which were further analyzed for diagnostic procedures and findings. Among the 200 articles we identified only 11 cases in which endoscopy was performed. Results of endoscopy and laparotomy in our patient with malignant atrophic papulosis were compared to those in the literature. Endoscopy of the gastrointestinal tract has shown gastritis and non-specific inflammation whereas laparoscopy shows white plaques with red borders on the serosal surface of the small bowel and the peritoneum. From personal communications with other physicians worldwide, we identified three additional unpublished cases in which endoscopy revealed only minimal changes while laparoscopy showed dramatic lesions. From our experience the endoscopic findings are often subtle and nonspecific, whereas laparascopy or laparotomy

To investigate the feasibility and safety of Da Vinci surgical robot in the dissection of splenic hilar lymph nodes for gastric cancer patients with total gastrectomy. Clinical data of two cases who underwent total gastrectomy for cardia cancer at our department in January 2016 were analyzed retrospectively. Two male patients were 62 and 55 years old respectively, with preoperative diagnosis as cT2-3N0M0 and cT1-2N0M0 gastric cancer by gastroscope and biopsy, and both received robotic total gastrectomy spleen-preserving splenic hilar lymph node dissection successfully. The operative time for splenic hilar lymph node dissection was 30 min and 25 min respectively. The intraoperative estimated blood loss was both 100 ml, while the number of total harvested lymph node was 38 and 33 respectively. One dissected splenic hilar lymph node and fatty tissues in two patients were proven by pathological examinations. There were no anastomotic leakage, pancreatic fistula, splenic infarction, intraluminal bleeding, digestive tract bleeding, aneurysm of splenic artery, and other operation-associated complications. Both patients suffered from postoperative pneumonia, and were cured by conservative therapy. The robotic spleen-preserving splenic hilar lymph node dissection is feasible and safe, but its superiority needs further evaluation.

The effectiveness of sleeve gastrectomy has been confirmed in many studies. The impact of individual factors on the parameters of weight loss is still not clear. To identify important factors affecting the parameters of weight loss after sleeve gastrectomy. The impact of prognostic factors and postoperative care components on body mass index (BMI) and percentage excess weight loss (%EWL) was assessed in a group of 100 consecutive patients who underwent laparoscopic sleeve gastrectomy. The baseline BMI and body mass in patients with BMI < 30 kg/m 2 and BMI ≥ 30 kg/m 2 12 months after surgery were, respectively, 39.7 ±3.2 vs. 45.9 ±4.6 kg/m 2 , p < 0.0001, and 114.4 ±16.8 vs. 130.3 ±18.5 kg, p < 0.0001. In the group with EWL < 50%, the average age was 47.1 ±7.7 vs. 40.6 ±10.8 in the group with EWL ≥ 50%, p = 0.0025. In the group of patients with preoperative weight loss, %EWL was 61.4 ±17.2 vs. 53.3 ±19.3% in the group with no weight loss, p = 0.0496. Body mass index of the patients who started physical activities was 30.6 ±4.2 kg/m 2 vs. 34.0 ±5.6 kg/m 2 in the patients with no physical activity, p = 0.0013, and %EWL was 63.4 ±14.6 vs. 47.0 ±19.9%, p < 0.0001, respectively. In the case of patients regularly consulted by a dietician BMI was 30.6 ±4.2 kg/m 2 vs. 35.1 ±5.5 kg/m 2 in the group without systematic consultations, p < 0.0001, and %EWL was 63.1 ±15.1% vs. 42.3 ±18.2%, p < 0.0001. Lower baseline body weight parameters, younger age, preoperative weight loss, starting systematic physical activities and constant care of a dietician were conducive to achieving better results of surgery, as assessed on the basis of changes in BMI and %EWL.

AIM: To investigate the role of second-look laparoscopy in patients with acute mesenteric ischemia (AMI). METHODS: Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room. RESULTS: The average time of admission to the hospital after the initiation of symptoms was 3 d (range, 5 h-9 d). In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% (n = 6). CONCLUSION: Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis.

Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

2017-05-01

Full Text Available Background: In recent years, laparoscopic sleeve gastrectomy (LSG has become more acceptable for obese patients. Single-port sleeve gastrectomy (SPSG is more popular since each abdominal incision carries the risk of bleeding, hernia, and internal organ injury as well as exponentially affecting cosmesis. This cross-sectional study aimed at comparing multi-port sleeve gastrectomy (MPSG and SPSG in terms of their early results and complications. Methods: Out of129 obese patients candidated for LSG, 102 patients were assigned to 2 groups of SPSG and MPSG. Complications and demographic data such as body mass index (BMI, age, gender, operation time, and hospital stay were measured. All surgeries were carried out between2013 and 2015 in Shiraz, Iran. Data analysis was performed using SPSS, version 16 for Windows (SPSS Inc., Chicago, IL. The continuous and categorical variables were compared using the Student t-test and the Chi-square test or the Fisher exact test, respectively. Results: The patients’ data from both groups were similar in terms of age, intraoperative and postoperative bleeding volume, and length of hospital stay. Mean BMI was 42.8±0.7 in the SPSG group and 45.3±1.2 in the MPSG group. Duration of surgery was significantly lower in the SPSG group (P<0.001. Only 1 patient from the SPSG group and 5 patients from the MPSG group had bleeding as an early complication. Conclusion: The differences in each complication between the groups were not statistically significant. SPSG seems to be safe and is the same as MPSG in terms of major postoperative complications.

Full Text Available Objective: In addition to adipocytes, adipose tissue contains large numbers of immune cells. A wide range of evidence links the activity of these cells to regulation of adipocyte and systemic metabolic function. Bariatric surgery improves several aspects of metabolic derangements and at least some of these effects occur in a weight-loss independent manner. We sought to investigate the impact of vertical sleeve gastrectomy (VSG on adipose immune cell frequencies. Methods: We analyzed the frequencies of immune cells within distinct adipose tissue depots in obese mice that had VSG or sham surgery with a portion of the latter group pair-fed such that their body mass was matched to the VSG animals. Results: We demonstrate that VSG induced a shift in the epididymal adipose tissue leukocyte profile including increased frequencies of CD11c− macrophages, increased frequencies of T cells (CD4+, CD8+, and CD4−/CD8− T cells all increased, but a significantly decreased frequency of adipose tissue dendritic cells (ATDC that, despite the continued high fat feeding of the VSG group, dropped below control diet levels. Conclusions: These results indicate that VSG induces substantial changes in the immune populations residing in the adipose depots independent of weight loss.

Adjustable gastric banding and vertical banded gastroplasty are associated with the worst postoperative food tolerance of all bariatric techniques. However, food tolerance tends to improve over time. The aim of this study was to assess food tolerance and diet quality in patients undergoing a sleeve gastrectomy, 1 and 5 years after surgery. A prospective observational study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy was performed. Food tolerance was assessed using the Quality of Alimentation questionnaire validated in bariatric patients. Ninety-three patients were analyzed. One year after surgery, mean excess weight loss (EWL) was 81.1% ± 8.3%, and 5 years after surgery, mean EWL was 79.9% ± 6.4%. Preoperatively, 39.8% of patients perceived their eating patterns as good or excellent, 1 year after surgery, 79.6% and 5 years postoperatively, 86%. One year after surgery, the patients reported some difficulty in tolerance of rice, pasta, and red meat. Five years after surgery, these difficulties disappeared and very few patients just refer some tolerance difficulties with red meat. One year after surgery, 10% of the patients reported that they suffered postprandial vomiting often and 22% rarely. Five years postoperatively, only 8% of subjects describe rarely vomiting. After sleeve gastrectomy, the patients recognize an improvement in the quality of alimentation. During the first postoperative year, they present tolerance problems with rice, pasta, and red meat, and that disappeared 5 years after surgery.

Single-port laparoscopy has gained popularity within minimally invasive gynecologic surgery for its feasibility, cosmetic outcomes, and safety. However, within gynecologic oncology, there are limited data regarding short-term adverse outcomes and long-term hernia risk in patients undergoing single-port laparoscopic surgery. The objective of the study was to describe short-term outcomes and hernia rates in patients after single-port laparoscopy in a gynecologic oncology practice. A retrospective, single-institution study was performed for patients who underwent single-port laparoscopy from 2009 to 2015. A univariate analysis was performed with χ 2 tests and Student t tests; Kaplan-Meier and Cox proportional hazards determined time to hernia development. A total of 898 patients underwent 908 surgeries with a median follow-up of 37.2 months. The mean age and body mass index were 55.7 years and 29.6 kg/m 2 , respectively. The majority were white (87.9%) and American Society of Anesthesiologists class II/III (95.5%). The majority of patients underwent surgery for adnexal masses (36.9%) and endometrial hyperplasia/cancer (37.3%). Most women underwent hysterectomy (62.7%) and removal of 1 or both fallopian tubes and/or ovaries (86%). Rate of adverse outcomes within 30 days, including reoperation (0.1%), intraoperative injury (1.4%), intensive care unit admission (0.4%), venous thromboembolism (0.3%), and blood transfusion, were low (0.8%). The rate of urinary tract infection was 2.8%; higher body mass index (P = .02), longer operative time (P = .02), smoking (P = .01), hysterectomy (P = .01), and cystoscopy (P = .02) increased the risk. The rate of incisional cellulitis was 3.5%. Increased estimated blood loss (P = .03) and endometrial cancer (P = .02) were independent predictors of incisional cellulitis. The rate for surgical readmissions was 3.4%; higher estimated blood loss (P = .03), longer operative time (P = .02), chemotherapy alone (P = .03), and

Current efforts in surgical simulation very often focus on creating realistic graphical feedback, but neglect some or all tactile and force (haptic) feedback that a surgeon would normally receive. Simulations that do include haptic feedback do not typically use real tissue compliance properties, favoring estimates and user feedback to determine realism. When tissue compliance data are used, there are virtually no in vivo property measurements to draw upon. Together with the Center for Innovative Minimally Invasive Therapy at the Massachusetts General Hospital, the Haptics Group is developing tools to introduce more comprehensive haptic feedback in laparoscopy simulators and to provide biological tissue material property data for our software simulation. The platform for providing haptic feedback is a PHANToM Haptic Interface, produced by SensAble Technologies, Inc. Our devices supplement the PHANToM to provide for grasping and optionally, for the roll axis of the tool. Together with feedback from the PHANToM, which provides the pitch, yaw and thrust axes of a typical laparoscopy tool, we can recreate all of the haptic sensations experienced during laparoscopy. The devices integrate real laparoscopy toolhandles and a compliant torso model to complete the set of visual and tactile sensations. Biological tissues are known to exhibit non-linear mechanical properties, and change their properties dramatically when removed from a living organism. To measure the properties in vivo, two devices are being developed. The first is a small displacement, 1-D indenter. It will measure the linear tissue compliance (stiffness and damping) over a wide range of frequencies. These data will be used as inputs to a finite element or other model. The second device will be able to deflect tissues in 3-D over a larger range, so that the non-linearities due to changes in the tissue geometry will be measured. This will allow us to validate the performance of the model on large tissue

Post-gastrectomy weight loss is associated with deterioration in quality of life, and influences the long-term prognosis of gastric cancer patients. We conducted a prospective, randomized controlled, open-label study to examine whether an oral elemental diet (Elental(®), Ajinomoto Pharmaceuticals, Tokyo, Japan; hereafter referred to as ED) prevents postoperative weight loss in post-gastrectomy patients. Patients were randomly divided to receive the ED or control diet. The ED group received 300 kcal of ED plus their regular diet for 6-8 weeks after surgery, starting from the day the patient started a soft rice or equivalent diet after surgery, while the control group received the regular diet alone. The primary endpoint was the percentage of body weight loss (%BWL) from the presurgical body weight to that at 6-8 weeks after surgery. Secondary endpoints were dietary adherence, nutrition-related blood parameters, and adverse events. This study included 112 patients in eight hospitals. The mean treatment compliance rate in the ED group was 68.7 ± 30.4 % (median 81.2 %). The %BWL was significantly different between the ED and control groups (4.86 ± 3.72 vs. 6.60 ± 4.90 %, respectively; p = 0.047). In patients who underwent total gastrectomy, the %BWL was significantly different between the two groups (5.03 ± 3.65 vs. 9.13 ± 5.43 %, respectively; p = 0.012). In multivariate analysis, ED treatment, surgery type, and preoperative performance status were independently associated with %BWL. No significant differences were observed in the other clinical variables. ED supplementation reduced postoperative weight loss in gastric cancer patients undergoing gastrectomy.

Methods: This study was designed as a prospective, nonblinded, randomized, parallel clinical trial (Trial Number: MN Ostrava, 200604. With informed consent, patients undergoing gastrectomy for malignancy were randomized to J-pouch or Roux-en-Y reconstruction. The time taken for a test semisolid meal labeled with 99mTc-sulfur colloid to exit the reconstructed parts was measured by dynamic scintigraphy 1 year after resection. Quality of life was measured using the Eypasch questionnaire at the same time as functional emptying assessment. This trial was investigator-initiated. Results: In all, 72 patients were included into the study. The time taken for the test meal to exit the postgastrectomy reconstruction was 16.5±10.0 minutes (mean ± standard deviation in the Roux-en-Y group and 89.4±37.8 minutes in the “J-pouch” group; the difference was statistically significant (P<0.001. Emptying of the J-pouch appeared to be a linear decreasing function compared to the exponential pattern seen in the Roux-en-Y group. The quality of life measurement showed scores of 106±18.8 points (mean ± standard deviation in the Roux-en-Y group compared to 122±22.5 points in the J-pouch group; the difference was statistically significant (P=0.0016. There were no important adverse events. Conclusion: After total gastrectomy, a J

To clarify the role of splenectomy in total gastrectomy for proximal gastric cancer. Splenectomy in total gastrectomy is associated with increased operative morbidity and mortality, but its survival benefit is unclear. Previous randomized controlled trials were underpowered and inconclusive. We conducted a multiinstitutional randomized controlled trial. Proximal gastric adenocarcinoma of T2-4/N0-2/M0 not invading the greater curvature was eligible. During the operation, surgeons confirmed that R0 resection was possible with negative lavage cytology, and patients were randomly assigned to either splenectomy or spleen preservation. The primary endpoint was overall survival (OS) and the secondary endpoints were relapse-free survival, operative morbidity, operation time, and blood loss. The trial was designed to confirm noninferiority of spleen preservation to splenectomy in OS with a noninferiority margin of the hazard ratio as 1.21 and 1-sided alpha of 5%. Between June 2002 and March 2009, 505 patients (254 splenectomy, 251 spleen preservation) were enrolled from 36 institutions. Splenectomy was associated with higher morbidity and larger blood loss, but the operation time was similar. The 5-year survivals were 75.1% and 76.4% in the splenectomy and spleen preservation groups, respectively. The hazard ratio was 0.88 (90.7%, confidence interval 0.67-1.16) (splenectomy should be avoided as it increases operative morbidity without improving survival.

The current system of surgical education is facing many challenges in terms of time efficiency, costs, and patient safety. Training using simulation is an emerging area, mostly based on the experience of other high-risk professions like aviation. The goal of simulation-based training in surgery is to develop not only technical but team skills. This learning environment is stress-free and safe, allows standardization and tailoring of training, and also objectively evaluate performances. The development of simulation training is straightforward in endourology, since these procedures are video-assisted and the low degree of freedom of the instruments is easily replicated. On the other hand, these interventions necessitate a long learning curve, training in the operative room is especially costly and risky. Many models are already in use or under development in all fields of video-assisted urologic surgery: ureteroscopy, percutaneous surgery, transurethral resection of the prostate, and laparoscopy. Although bench models are essential, simulation increasingly benefits from the achievements and development of computer technology. Still in its infancy, virtual reality simulation will certainly belong to tomorrow's teaching tools.

Distal radius fractures (DRF) are often referred to as osteoporosis indicator fractures as their incidence increases from age 45. In the group of young adults, distal radius fractures normally result from high-energy trauma. Wrist fractures in young patients without adequate trauma thus raise suspicion of a pathologic fracture. In this report we present the case of a fractured unicameral bone cyst (UBC) at the distal radius in a young adult.To the author's best knowledge, this is the first detailed report in an UBC at the distal radius causing a pathologic DRF in an adult patient. A 25-year-old otherwise healthy male presented to our Emergency Department after a simple fall on his right outstretched hand. Extended diagnostics revealed a pathologic, dorsally displaced, intra-articular distal radius fracture secondary to a unicameral bone cyst occupying almost the whole metaphysis of the distal radius. To stabilize the fracture, a combined dorsal and volar approach was used for open reduction and internal fixation. A tissue specimen for histopathological examination was gathered and the lesion was filled with an autologous bone graft harvested from the ipsilateral femur using a reamer-irrigator-aspirator (RIA) system. Following one revision surgery due to an intra-articular step-off, the patient recovered without further complications. Pathologic fractures in young patients caused by unicameral bone cysts require extended diagnostics and adequate treatment. A single step surgical treatment is reasonable if fracture and bone cyst are treated appropriately. Arthroscopically assisted fracture repair may be considered in intra-articular fractures or whenever co-pathologies of the carpus are suspected.

To assess the outcome of surgical therapy and choice of surgical strategy for patients with adenocarcinoma of the gastroesophageal junction. Between February 1989 and January 2005 during 16 years, 335 patients (65 female, 270 male, mean age 56 years) with esophagogastric junction adenocarcinoma underwent surgical operation. The choice of surgical approach was based on the anatomical location of the tumor mass. Outcome of surgery, histopathologic characteristics, demographic data and long term survival rates were compared among three types of tumor defined as follows. Type I: Adenocarcinoma of the distal esophagus which infiltrates the esophagogastric junction from above. Type II: True carcinoma of the cardia arising immediately at the esophagogastric junction. Type III: Subcardial gastric carcinoma that infiltrates the esophagogastric junction and distal esophagus from below. Of the 335 patients undergoing resection, 110 (33%) had type I, 96 (28%) had type II, and 129 (39%) had type III. The preponderance of the male sex and the prevalence of metaplasia in distal esophagus decreased from type I to type III tumors (P<0.01). The prevalence of undifferentiated tumors increased from type I to type III tumors (P<0.01). Esophagectomy with resection of the proximal stomach for type I and extended total gastrectomy with transhiatal resection of the distal esophagus for type II and III were the primary procedures. The mean number of removed lymph node was higher in type III and II compared to type I tumors. The overall postoperative 30-day mortality was 8.4%. The death rate in transthoracic esophagectomy was higher than with extended total gastrectomy. The classification of adenocarcinoma of the esophagogastric junction into type I, II and III tumors helps in the selection of surgical approach. Type I tumors are approached as distal esophageal cancer. Type III tumors are a special form of gastric cancer and treated as a gastric cancer. The relation of type II tumors to

This study aimed to compare the degree of gastric food stasis and following body fat changes after laparoscopic subtotal gastrectomy (LSTG) versus open subtotal gastrectomy (OSTG). For 284 consecutive gastric cancer patients who underwent subtotal gastrectomy (213 LSTG and 71 OSTG), the one-year follow-up CT images were reviewed retrospectively. The characteristics of gastric stasis was divided into 5 degrees (0, no residue; 1, small secretion; 2, poorly-defined amorphous food; 3, well-delineated measurable food; 4, bezoar-like food). The residual food volume was calculated for the patients with degree 3 or 4 gastric stasis. Postoperative visceral, subcutaneous, and total fat changes were measured on CT and were correlated with the residual food volume. The LSTG group showed higher degrees of gastric stasis [degree 3 (LSTG, 15.0%; OSTG, 9.9%), degree 4 (LSTG, 6.5%; OSTG, 2.8%)] (p = 0.072). The mean residual food volume of the LSTG group was larger than that of the OSTG group (13779 cc versus 6295 cc) (p = 0.059). Postoperative abdominal fat change was not significantly different between the 2 groups and was not correlated with the residual food volume. LSTG tends to develop gastric stasis more frequently compared with OSTG, but gastric stasis might hardly affect the postoperative body fat status.

Laparoscopic sleeve gastrectomy (SG) represents, at present, the most performed bariatric procedure worldwide with excellent long-term results on weight loss and comorbidities control. After the gastrectomy procedure, together with hormonal modification, several changes in taste and habits occur, including the potential modification in alcohol consumption. The aim of this prospective study was to determine the frequency and the amount of alcohol use before and after SG using a modified version of the Alcohol Use Disorder Identification Test (AUDIT) at 1-year follow-up and eventually to evaluate relationships between different ages and sexes. A total of 142 patients were prospectively enrolled and evaluated before and 1 year after SG with a modified AUDIT. The exclusion criteria were as follows: history of alcohol abuse, presence of psychopathology or cognitive impairments, diabetes mellitus type II decompensated, or previous gastrointestinal, liver, and pancreatic resective surgery. Subgroup analyses were performed between male and female and between under and over 40 years old. The median AUDIT score decreased from 2.70 (range 1-18) before surgery to 1.38 (range 1-7) after 1 year of SG, indicating a marked reduction in alcohol use. The most consumed alcoholic drink was beer (36.6%/n = 52) while after surgery the consumption of beer decreased considerably (21.1%/n = 30). The frequency of alcohol consumption also decreased: at baseline 45% of patients consumed alcoholic drinks "from 2 to 4 times per month", whereas 26 and 39.4% consumed alcohol "never" and "less than once a month," respectively. After surgery, nobody consumed more then six alcoholic drinks. No differences were found between the subgroups in terms of alcohol consumption and social behavior. The alcohol preference is modified and decreased 1 year after SG and this could be related to the strict nutritional follow-up and to the hormonal changes. Studies with large samples and long

Bariatric surgery has shown to be safe for patients over 60 years with good results especially considering resolving of comorbidities. Sleeve gastrectomy is considered to be safer than gastric bypass (GBP) and more effective than gastric banding with less adverse symptoms. Weight loss may be more modest than after GBP, but the effect on vitamins may also be milder. Since 2007, we collected prospectively 12-month follow-up data from 55 sleeve gastrectomy patients of whom 12 were over 59 years of age. Vitamin and calcium supplements were used postoperatively. The recovery from the operation was recorded during hospital stay, at 1- and 12-month follow-up visits using a standard protocol including laboratory tests. The results between patients over and under 59 years were compared. The preoperative weight and weight loss were comparable between the groups. Operation time was shorter and hospital stay was longer for older patients, p = ns. There was no operative mortality. Early major complications were seen more often in the older age group, 42% vs 9% (p = 0.02), but late complications were more common in younger patients, 17% vs 44%, p = ns. Early complications were mostly bleedings, which did not lengthen the hospital stay, neither were re-operations nor endoscopic procedures needed. Excess weight loss and resolving of comorbidities after 12 months was comparable between the groups. However, vitamin deficiencies and hypoalbuminemia were more common in the older age group, 42% and 23% for vitamins and 44% and 29% for proteins, p = ns. The older patients had more adverse effects related to surgery, 25% vs 9%, and younger had more adverse psychiatric effects, p = ns. Sleeve gastrectomy is effective and safe for older bariatric patients. Weight loss is comparable to younger patients and enough to resolve the comorbidities in most of the patients. With standardized nutritional supplementation, the older patients had more often vitamin deficiencies and

We present the first laparoscopically assisted vaginal hysterectomy (LAVH) performed in our centre and indeed in southeast Nigeria. The case records of a 60 year old post menopausal woman; Para 6(+2) with moderate cystocele, treated at the Nnamdi Azikiwe University Teaching Hospital in July 2007 was retrieved for presentation. A 60 year old post menopausal woman, Para 6(+2) with moderate cystocele, no descent of the cervix and narrowed vagina. LAVH and anterior colporraphy was performed. She had an uneventful post operative stay and was discharged home. She has not experienced any complication one year after the procedure. LAVH is our first major gynaecological laparoscopy surgery and we consider it an important breakthrough worthy of reporting.

To review the global select data on the current technique, perioperative outcome and literature on the robot-assisted pyeloplasty (RAP). The published English literature (PubMed) was extensively searched using the key words; robot, robot-assisted pyeloplasty, laparoscopy, laparoscopic pyeloplasty and ureteropelvic junction obstruction. The selected studies were then reviewed, tracked and analyzed in order to determine the current role, outcome and status of robot-assisted laparoscopic pyeloplasty. The search yielded about 25 published series on RAP comprising about 740 cases with a mean operative time, estimated blood loss, crossing vessel prevalence, hospital stay,perioperative complication rate and follow up duration of 194 min, 50 mL, 47%, 2.3 days, 6% and 14.9 months respectively. The initial peri-operative results and intermediate follow up of cases of repair of the ureteropelvic junction obstruction with robot-assisted pyeloplasty appear to be favorable and comparable to that of open pyeloplasty, while long term outcome data is still awaited. The da Vinci surgical robotic system is a promising surgical armamentarium in the hands of the modern day urologist for the minimally invasive definitive surgical management of both primary and secondary ureteropelvic junction obstruction.

Inactivating mutations in the CDH1 (E-cadherin) gene are the predisposing cause of gastric cancer in most families with hereditary diffuse gastric cancer (HDGC). The lifetime risk of cancer in mutation positive members is more than 80 % and prophylactic total gastrectomy is recommended. Not all...... mutations in the CDH1 gene are however pathogenic and it is important to classify mutations before this major operation is performed. Probands from two Danish families with gastric cancer and a history suggesting HDGC were screened for CDH1 gene mutations. Two novel CDH1 gene mutations were identified....... Hospital stay was 6-8 days and there were no complications. Small foci of diffuse gastric cancer were found in all patients-intramucosal in six and advanced in one. Preoperative endoscopic biopsies had revealed a microscopic cancer focus in two of the patients. Our data confirmed the pathogenic nature...

We undertook this study to determine the feasibility and analgesic efficacy of ultrasound-guided TAP blocks in morbidly obese patients. We describe the dermatomal spread of local anesthetic in TAP blocks administered, and test the hypothesis that TAP blocks decrease visual analog scale (VAS scores.Patients and methods: After ethics committee approval and informed consent, 35 patients with body mass index >35 undergoing single-port sleeve gastrectomy (SPSG were enrolled. All patients received balanced general anesthesia, followed by intravenous patient-controlled analgesia (IV-PCA; hydromorphone postoperatively; all reported VAS >3 upon arrival to the recovery room. From the cohort of 35 patients having single-port laparoscopy (SPL, a sealed envelope method was used to randomly select ten patients to the TAP group and 25 patients to the control group. The ten patients in the TAP group received ultrasound-guided TAP blocks with 30 mL of 0.2% Ropivacaine injected bilaterally. The dermatomal distribution of the sensory block (by pinprick test was recorded. VAS scores for the first 24 hours after surgery and opioid use were compared between the IV-PCA+TAP block and IV-PCA only groups.Results: Sensory block ranged from T5–L1. Mean VAS pain scores decreased from 8 ± 2 to 4 ± 3 (P=0.04 within 30 minutes of TAP block administration. Compared with patients given IV-PCA only, significantly fewer patients who received TAP block had moderate or severe pain (VAS 4–10 after block administration at 6 hours and 12 hours post-surgery.

Internal herniations through broad ligament defects are very rare. We present the first report of the triad of broad ligament defect, internal herniation of the caecum and appendicitis. A 36-year-old woman with phocomelia presented with right iliac fossa pain and vomiting. The patient had no previous history of trauma or surgery. Abdominal ultrasound showed a small amount of free fluid. At laparoscopy, bilateral broad ligament defects were found, with herniation of the caecum and an inflamed appendix through the right-sided defect. A laparoscopic salpingo-oophorectomy was required for reduction of the herniated bowel, and an appendicectomy was performed. Broad ligament defects may be congenital or acquired. In this case, in light of the limb abnormality and absence of previous surgery, a congenital aetiology is more likely. Ultrasound scan is not reliable and, although computed tomography may be of help, a diagnostic laparoscopy is the best investigation. PMID:20566032

Laparascopic-assisted nephroureterectomy for shaped urolithiasis and xanthogranulomatous pyelonephritis: Case report and review of literature

Directory of Open Access Journals (Sweden)

Valentina Pastore

2013-01-01

Full Text Available We report a case of xanthogranulomatous pyelonephritis (XGP complicated by shaped urolithiasis, severe hydroureteronephrosis and kidney exclusion treated by laparoscopic-assisted nephroureterectomy. A 9 year-old boy was referred to us for recurrent episodes of urinary tract infection, abdominal pain and severe hydronephrosis. Abdominal CT and a Tc-99m MAG3 scan showed a non-functioning obstructed kidney with shaped urolithiasis of the distal ureter. XGP was suspected, and nephroureterectomy was performed by laparoscopic distal ureterectomy and open extraperitoneal nephrectomy. This technique avoided the need for a more extended nephrectomy incision or even a second iliac incision. It also ensured complete excision of the distal ureter with minimal risk of developing the ureteral stump syndrome, which sometimes follows nephroureterectomy. We believe that laparoscopic-assisted nephroureterectomy may be a suitable technique in those cases of difficult nephrectomy where a ureteral stump syndrome is likely to develop.

In this work, a foldable ring-shaped light-emitting diode (LED) lighting assembly, designed to attach to a rubber wound retractor, is realized and tested through porcine animal experiments. Enabled by the small size and the high efficiency of LED chips, the lighting assembly is compact, flexible, and disposable while providing direct and high brightness lighting for more uniform background illumination in video-assisted thoracic surgery (VATS). When compared with a conventional fiber bundle coupled light source that is usually used in laparoscopy and endoscopy, the much broader solid angle of illumination enabled by the LED assembly allows greatly improved background lighting and imaging quality in VATS.

Background. Marginal ulcer is a well-known complication after gastrectomy. Its bleeding can be severe, but the severity has rarely been reported. We aim to evaluate the clinical outcomes of marginal ulcer bleeding (MUB) as compared to peptic ulcer bleeding (PUB) with nonoperated stomach. Methods. A consecutive series of patients who had nonvariceal upper gastrointestinal bleeding and admitted to the hospital between 2005 and 2011 were retrospectively analyzed. A total of 530 patients were enrolled in this study, and we compared the clinical characteristics between 70 patients with MUB and 460 patients with PUB. Results. Patients with MUB were older (mean age: 62.86 ± 10.59 years versus 53.33 ± 16.68 years, P = 0.01). The initial hemoglobin was lower (8.16 ± 3.05 g/dL versus 9.38 ± 2.49 g/dL, P = 0.01), and the duration of admission was longer in MUB (7.14 ± 4.10 days versus 5.90 ± 2.97 days, P = 0.03). After initial hemostasis, the rebleeding rate during admission was higher (16.2% versus 6.5%, P = 0.01) in MUB. However, the mortality rate did not differ statistically between MUB and PUB groups. Helicobacter pylori-positive rate with MUB was lower than that of PUB (19.4% versus 54.4%, P = 0.01). Conclusions. Clinically, MUB after gastrectomy is more severe than PUB with nonoperated stomach. Infection with H. pylori might not appear to play an important role in MUB after gastrectomy. PMID:23304127

reconstruction is the most preferred method following distal gastrectomy for Type I pyloric stricture.1. Conventionally, the Billroth I reconstruction is done by carrying out a limited resection of pre-pyloric stricture with the pylorus followed by gastroduodenal hand-sewn anastomosis. Although staplers have widely replaced.

Full Text Available When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the whole first part of the duodenum, complete omentectomy, bursectomy, and D2+ lymphadenectomy performed for a pT3pN2pM1 (+ number 13 lymph nodes adenocarcinoma of the antrum. Duodenal stump rupture was managed successfully by end tube duodenostomy, without omental patching, and tube cholangiostomy. Close assessment of clinical, physical, and radiological signs, output volume, and enzyme concentration of the tube duodenostomy, T-tube, and closed suction drain, which was placed near the tube duodenostomy site to drain the leak around the catheter, dictated postoperative management of the external duodenal fistula.

Endolymphatic Sac Enlargement in a Girl with a Novel Mutation for Distal Renal Tubular Acidosis and Severe Deafness

Full Text Available Hereditary distal renal tubular acidosis (dRTA is caused by mutations of genes encoding subunits of the H+-ATPase (ATP6V0A4 and ATP6V1B1 expressed in α-intercalated cells of the distal renal tubule and in the cochlea. We report on a 2-year-old girl with distal RTA and profound speech delay which was initially misdiagnosed as autism. Genetic analysis showed compound heterozygous mutations with one known and one novel mutation of the ATP6V1B1 gene; cerebral magnetic resonance imaging (MRI revealed bilateral enlargement of the endolymphatic sacs of the inner ear. With improved cooperation, audiometric testing showed that hearing loss was most profound on the right, where endolymphatic sac enlargement was greatest, demonstrating a clear link between the degree of deafness and the degree of inner ear abnormality. This case indicates the value of MRI for diagnosis of inner ear involvement in very young children with distal RTA. Although citrate therapy quickly corrects the acidosis and restores growth, early diagnosis of deafness is crucial so that hearing aids can be used to assist acquisition of speech and to provide enough auditory nerve stimulation to assure the affected infants remain candidates for cochlear implantation.

2009-07-01

We present herein a novel, combined, simultaneous open proximal and stent-graft distal repair for complex distal aortic arch aneurysms involving the descending aorta. In the first surgical step, the transverse arch is opened during selective antegrade cerebral perfusion, and a Dacron graft (DuPont, Wilmington, DE) is positioned down the descending aorta in an elephant trunk-like fashion with its proximal free margin sutured circumferentially to the aorta just distal to the left subclavian or left common carotid artery. With the graft serving as the new proximal landing zone, subsequent endovascular repair is performed antegrade during rewarming through the ascending aorta.

To investigate the association between distal clavicular osteolysis and subchondral fractures of the distal clavicle at MRI. This study was approved by the hospital human research committee, which waived the need for informed consent. Three radiologists retrospectively analyzed 36 shoulder MR examinations in 36 patients with imaging findings of distal clavicular osteolysis. The presence of a subchondral fracture of the distal clavicle, abnormalities of the acromioclavicular joint, rotator cuff tears and labral tears were assessed by MRI. These cases were then compared with 36 age-matched controls. At MRI, 31 of 36 patients (86%) had a subchondral line within the distal clavicular edema, consistent with a subchondral fracture. Of the 36 patients, 32 (89%) had fluid in the acromioclavicular joint, while 27 of 36 patients (75%) had cysts or erosions in the distal clavicle. There were 13 patients (36%) with associated labral tears, while eight patients (22%) had partial-thickness rotator cuff tears. In the control group one of 36 (3%) had a subchondral line (P<0.05), while ten of 36 (28%) had rotator cuff tears and 13 of 36 (36%) had labral tears. These latter two were not statistically significant between the groups. A distal clavicular subchondral fracture is a common finding in patients with imaging evidence of distal clavicular osteolysis. These subchondral fractures may be responsible for the propensity of findings occurring on the clavicular side of the acromioclavicular joint. (orig.)

Distal extremity of lower limb sustains the complications of loss of tissue: problem of coverage (cutaneous and tendon necrosis, osteoarticular infection. The whole point of the surgery is to fight against the infection by repeated debridments, against the deformations or their correction by early osteosynthesis (pins and external fixation). The coverage is very important in this treatment: either with Vacuum-Assisted Closure (VAC) and skin graft or fasciocutaneous flap. In spite of this management, the after-effects are important although the conservative treatment is the determining factor of satisfaction.

Full Text Available Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. Recently, many studies have addressed the laparoscopic management of these tumors. The aim of this study was to evaluate the safety and efficacy of laparoscopic atypical gastrectomy in the resolution of these neoplasms. In the period between January 2009 and December 2015, 24 patients with suspected gastric GIST less than 5 cm in size underwent surgery under this approach. Abscense of peritoneal and liver metastases and immunohistochemistry expression of CD117 antigen were considered as inclusion criteria. We retrospectively analyzed clinical and histopathological characteristics, surgical outcomes, postoperative complications and oncological results. Statistical analysis included 14 patients. The mean age was 60 years (10 women and 4 men and upper gastrointestinal bleeding was the chief complaint for consultation. Conversion to open surgery was necessary in one case and no major complications, readmissions or reoperations were recorded. The mean tumor size was 41 mm with negative resection margin in all samples. The mean hospital stay was 3 days and no tumor recurrences were recorded in 44 months of follow-up. Laparoscopic atypical gastrectomy for gastric GIST is a safe and effective technique with good outcomes in experienced hands

To study the feasibility and results (live-birth and complication rates) of placement of Essure(®) microinserts before assisted reproductive technology (ART) treatment of women with hydrosalpinx when laparoscopy should be avoided. Study design National survey of 45 French hospital centres providing ART reporting a retrospective analysis of 43 women with unilateral or bilateral hydrosalpinges and Essure(®) placement. The results of the following ART cycle were studied for 54 embryo transfers. The placement success rate reached 92.8% (65/70 tubes), and the mean number of visible intrauterine coils was 1.61 (range: 0-6). Pyosalpinx occurred in one case, and expulsion of the device into the uterus in two others. Of 43 women, 29 (67.4%) had a total of 54 fresh or frozen embryos transferred. The clinical pregnancy rate was 40.7% (22/54) and the live-birth rate 25.9% (14/54). The implantation rate was 29.3% (27/92). Essure(®) placement is an effective method for occlusion of hydrosalpinges before IVF. Monitoring the live-birth rate confirms that this option is the strongest in cases when laparoscopy is impossible or contraindicated. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

To determine long-term outcome associated with laparoscopic-assisted gastropexy in prevention of gastric dilatation-volvulus (GDV) in susceptible dogs and to evaluate use of laparoscopy to correct GDV. Prospective study. 25 client-owned large-breed dogs. 23 dogs susceptible to GDV were referred as candidates for elective gastropexy. These dogs had a history of treatment for gastric dilatation, clinical signs of gastric dilatation, or family members with gastric dilatation. Laparoscopic-assisted gastropexy was performed. One year after surgery, abdominal ultrasonography was performed to evaluate the attachment of the stomach to the abdominal wall. Two dogs with GDV were also treated with laparoscopic-assisted derotation of the stomach and gastropexy. None of the dogs developed GDV during the year after gastropexy, and all 20 dogs examined ultrasonographically had an intact attachment. Another dog was euthanatized at 11.5 months for unrelated problems. Two dogs with GDV successfully underwent laparoscopic-assisted gastropexy after the stomach was repositioned. Laparoscopic-assisted gastropexy resulted in a persisting attachment between the stomach and abdominal wall, an absence of GDV development, and few complications. Dogs with a high probability for development of GDV should be considered candidates for minimally invasive gastropexy. Carefully selected dogs with GDV can be treated laparoscopically.

An important yet difficult problem is qualification for surgery in elderly patients. With age the risk of comorbidities increases - multi-disease syndrome. Elderly patients suffer from frailty syndrome. Many body functions become impaired. All these factors make the elderly patient a major challenge for surgical treatment. Analysis of the possibility of developing the indications and contraindications and the criteria for surgical treatment of the elderly based on our own cases. Discussion whether there is a place for laparoscopy during surgery of the elderly in emergency room (ER) mode. The analysis was performed based on seven cases involving surgical treatment of elderly patients who were admitted to the hospital in emergency room mode. The patients were hospitalized in the General and Minimally Invasive Surgery Clinic in Olsztyn in 2016. Surgical treatment of elderly patients should be planned with multidisciplinary teams. Geriatric surgery centers should be developed to minimize the risk of overzealous treatment and potential complications. Laparoscopy should always be considered in the case of ER procedures or diagnostics. Elderly patients should not be treated as typical adults, but as a separate group of patients requiring special treatment. Due to the existing additional disease in the elderly, the frailty syndrome, any surgical intervention should be minimally invasive. The discussion about therapy should be conducted by a team of specialists from a variety of medical fields.

The aim of this study was to present the orthodontic treatment of a 15-year-old boy with a unilateral maxillary molar distalization system, called the zygoma-gear appliance. It consisted of a zygomatic anchorage miniplate, an inner bow, and a Sentalloy closed coil spring (GAC International, Bohemia, NY). A distalizing force of 350 g was used during the distalization period. The unilateral Class II malocclusion was corrected in 5 months with the zygoma-gear appliance. The maxillary left first molar showed distalization of 4 mm with an inclination of 3°. The maxillary premolars moved distally with the help of the transseptal fibers. In addition, there were slight decreases in overjet (-0.5 mm) and maxillary incisor inclination (-1°), indicating no anchorage loss from the zygoma-gear appliance. Preadjusted fixed appliances (0.022 × 0.028-in, MBT system; 3M Unitek, Monrovia, Calif) were placed in both arches to achieve leveling and alignment. After 14 months of unilateral distalization with the zygoma-gear appliance and fixed appliances, Class I molar and canine relationships were established with satisfactory interdigitation of the posterior teeth. Acceptable overjet and overbite were also achieved. This article shows that this new system, the zygoma-gear appliance, can be used for unilateral maxillary molar distalization without anchorage loss.

The albumin-bilirubin (ALBI) score was initially developed for assessing liver dysfunction severity and was suggested to have prognostic value in patients with hepatocellular carcinoma. We aimed to evaluate the prognostic impact of ALBI grade in patients with advanced gastric cancer (GC) after radical gastrectomy. This study included 283 patients who underwent radical gastrectomy for pT2-4 GC without preoperative treatment. ALBI was calculated as follows: (log 10 bilirubin (μmol/L) × 0.66) + (albumin (g/L) × -0.0852) and categorized into grades 1 (≤-2.60), 2 (-2.60<, ≤-1.39) and 3 (-1.39<). The median ALBI score was -2.96, and a number of patients in ALBI grades 1, 2 and 3 were 228, 55 and 0, respectively. Patients with ALBI grade 2 had a lower administration rate of adjuvant chemotherapy than those with ALBI grade 1, whereas no significant differences were found in morbidity rate and disease stage. The ALBI grade 2 group was more likely to have shorter disease-specific and disease-free survival compared with the ALBI grade 1 group. Multivariable analysis identified ALBI grade 2 as an independent prognostic factor for disease-free survival (hazard ratio 1.97, 95% confidence interval 1.10-3.47, p = 0.0242). Survival differences between ALBI grade 1 and 2 groups were increased in the patient subset that received adjuvant chemotherapy. ALBI grade 2 was correlated with a shortened duration of administration of postoperative S-1 adjuvant. ALBI grade serves as a simple and promising predictive factor for disease-free and disease-specific survival in patients with pT2-4 GC after radical gastrectomy.

Intra-Articular Osteotomy for Distal Humerus Malunion

Directory of Open Access Journals (Sweden)

René K. Marti

2009-01-01

Full Text Available Intra-articular osteotomy is considered in the rare case of malunion after a fracture of the distal humerus to restore humeral alignment and gain a functional arc of elbow motion. Traumatic and iatrogenic disruption of the limited blood flow to the distal end of the humerus resulting in avascular necrosis of capitellum or trochlea is a major pitfall of the this technically challenging procedure. Two cases are presented which illustrate the potential problems of intra-articular osteotomy for malunion of the distal humerus.

Volar plating for distal radius fractures--do not trust the image intensifier when judging distal subchondral screw length.

Science.gov (United States)

Park, Derek H; Goldie, Boyd S

2012-09-01

The use of the volar plate to treat distal radius fractures is increasing but despite the theoretical advantages of a volar approach there have been reports of extensor tendon ruptures due to prominent screw tips protruding past the dorsal cortex. The valley in the intermediate column between Lister tubercle and the sigmoid notch of the distal radius makes it difficult to rely on fluoroscopy to judge screw length. Our aim was to quantify the dimensions of this valley and to demonstrate the danger of relying on intraoperative image intensification fluoroscopy to determine lengths of distal screws. We measured the depth of this valley in the intermediate column of the distal radius in 33 patients with computed tomographic (9 patients) or magnetic resonance image (24 patients) scans of the wrist. There was a consistent valley in all images examined [average 1.8 mm (95% confidence interval, 1.6-2.0 mm)]. Thirty-nine percent of wrists had a valley depth of at least 2 mm. Standard lateral views or rotation of the forearm to obtain oblique views does not identify prominent screw tips; and whatever the rotation of the forearm, screw tips protruding beyond dorsal cortex may look as if it is within the bone when in fact it is out. When drilling we suggest noting the depth at which the drill bit just penetrates dorsal cortex and routinely downsize the distal screw length by 2 mm. We caution against relying on flourosocopy when judging the length of the distal subchondral screws.

To evaluate the impact of obesity on the outcomes of surgical treatment for endometrial cancer in general and also comparing laparoscopic and open abdominal approach. Retrospective case-control study (Canadian Task Force classification II-1). Obstetrics and Gynecology Department, University of Insubria, Varese, Catholic University of the Sacred Heart, Rome, International School of Surgical Anatomy, Sacred Heart Hospital, Negrar, and Sant'Orsola-Malpighi Hospital, Bologna, Italy. Data of consecutive patients who underwent surgery for endometrial cancer in 4 centers were reviewed. Univariate and multivariable analyses were performed. Adjustment for potential selection bias in surgical approach was made using propensity score (PS) matching. Laparoscopic or open surgical treatment for endometrial cancer. A total of 1266 patients were included, including 764 in the laparoscopy group and 502 in the open surgery group. A total of 391 patients (30.9%) were obese, including 238 (18.8%) with class I obesity, 89 (7%) with class II obesity, and 64 (5.1%) with class III obesity. The total number of complications, risk of wound complications, and venous thromboembolic events were higher in obese women compared with nonobese women. Blood transfusions, incidence/severity of postoperative complications, and postoperative hospital stay were significantly higher in the open surgery group compared with the laparoscopy group, irrespective of obesity. These differences remained significant in both multivariable analysis and PS-matched analysis. The percentage of patients who received lymphadenectomy declined significantly in patients with BMI ≥40 in both the laparoscopy and open surgery groups. Conversions from the initially intended minimally invasive approach to open surgery were 1.1% to 2.2% for women with BMI obese women in the laparoscopic group. Laparoscopy for endometrial cancer retains its advantages over open surgery, even in obese patients. However, operating on obese

Arthroscopic-Assisted Triangular Fibrocartilage Complex Reconstruction.

Chu-Kay Mak, Michael; Ho, Pak-Cheong

2017-11-01

Injury of the triangular fibrocartilage complex (TFCC) is a common cause of ulnar-sided wrist pain. Volar and dorsal radioulnar ligaments and their foveal insertion are the most important stabilizing components of the TFCC. In irreparable tears, anatomic reconstruction of the TFCC aims to restore normal biomechanics and stability of the distal radioulnar joint. We proposed a novel arthroscopic-assisted technique using a palmaris longus tendon graft. Arthroscopic-assisted TFCC reconstruction is a safe and effective approach with outcomes comparable to conventional open reconstruction and may result in a better range of motion from minimizing soft tissue dissection and subsequent scarring.

Conceptualizing distal drivers in land use competition

DEFF Research Database (Denmark)

Niewhöner, Jörg; Nielsen, Jonas Ø; Gasparri, Gasparri

2016-01-01

This introductory chapter explores the notion of ‘distal drivers’ in land use competition. Research has moved beyond proximate causes of land cover and land use change to focus on the underlying drivers of these dynamics. We discuss the framework of telecoupling within human–environment systems...... as a first step to come to terms with the increasingly distal nature of driving forces behind land use practices. We then expand the notion of distal as mainly a measure of Euclidian space to include temporal, social, and institutional dimensions. This understanding of distal widens our analytical scope...... for the analysis of land use competition as a distributed process to consider the role of knowledge and power, technology, and different temporalities within a relational or systemic analysis of practices of land use competition. We conclude by pointing toward the historical and social contingency of land use...

Saber, Alan A; Shoar, Saeed; Khoursheed, Mousa

2017-08-01

Despite its technical simplicity, laparoscopic sleeve gastrectomy (LSG) complications are increasingly reported. Intra-thoracic sleeve migration (ITSM ) is a rare complication after LSG which has been inconsistently addressed in the literature. The purpose of this study was to emphasize ITSM occurrence after LSG and evaluate the perioperative factors associated with its development. Between January and July 2016, LSG patients diagnosed with ITSM at two bariatric surgery departments were identified. Perioperative factors were assessed for all the patients and compared between two groups, LSG alone and LSG with concomitant hiatal hernia (HH) repair (HHR). A total of 19 patients (6 males and 13 females) were included. Central obesity was present in 18 patients (94.7%). Nine patients (47.4%) had concomitant hiatal hernia repair during their original LSG. Post-LSG GERD (94.7%) (38.9% de novo and 61.1% recurrent) and post-LSG constipation (57.9%) were commonly associated with ITSM. Severe refractory GERD was the most common presentation for ITSM (94.7%), followed by epigastric pain (47.4%), persistent nausea/vomiting (36.8%), and dysphagia (21.1%). Time interval between primary LSG and ITSM diagnosis ranged from 1 day to 3 years. Patients with LSG and concomitant HHR presented with higher post-LSG BMI compared to the LSG patients (37 ± 6.4 kg/m 2 vs. 30.1 ± 6.3 kg/m 2 , p = 0.03). All the patients underwent successful reduction of ITSM and subsequent HHR. Central obesity, chronic constipation, post-LSG GERD, and concomitant HHR are commonly seen in post-laparoscopic sleeve gastrectomy intra-thoracic sleeve migration.

To evaluate the chance of adhesion formation after laparoscopic salpingo-ovariolysis and determine the efficacy of early second-look laparoscopy (SLL). Prospective, randomized study (Canadian Task Force classification I). Shiraz University hospitals. Ninety women with mean duration of infertility of 7.2 years. Operative laparoscopy, with early SLL with adhesiolysis in 46 (group 1) and no SLL in 44 women (group 2). Adnexal adhesions were evaluated according to American Society for Reproductive Medicine adhesion classification. Separation of newly reformed adhesions was performed at the time of SLL. Patients were followed for a year after operation without other infertility treatment. At the time of operation in group 1, adnexal adhesions were graded as severe (class D) in 19 women, moderate (class C) in 31, mild (class B) in 28, and minimal (class A) in 14. Respective figures in group 2 were 10, 30, 34, and 14. After salpingo-ovariolysis these figures were 12, 10, 20, and 50 in group 1 and 6, 14, 17, and 51 in group 2. In group 1 in whom early second-look laparoscopy was performed, at the start of the operation these figures were 17, 20, 21, and 34, and after operation 12, 8, 20, and 52, respectively. There were 11 term pregnancies in group 1 and 15 in group 2. No women with severe adhesions in either group conceived. In group 1, chances of term pregnancy were 18.75% for those with moderate adhesions, 35.71% for women with mild adhesions, and 42.86% in patients with minimal adhesions. Respective figures in group 2 were 26.67%, 41.18%, and 57.14%. The chance of moderate and severe adhesion reformation after laparoscopic salpingo-ovariolysis was 40.2%. Although separation of these adhesions could be performed more easily at the time of early SLL, the chance of pregnancy did not increase compared with that in patients who did not undergo SLL.

From the Automated Endoscopic System for Optimal Positioning (AESOP), a robotic arm which operates the laparoscope, to the robots Zeus and da Vinci, robotic assistance in gynaecological endoscopic surgery has continuously evolved for the last fifteen years or so. It has brought about new technical advancements: the last generation robots offer a steady three-dimensional image, improved instrument dexterity and precision, higher ergonomics and comfort for the surgeon. The da Vinci robotic system has been used without evincing any specific morbidity in various cases, notably for tubal reanastomosis, myomectomy, hysterectomy, pelvic and para-aortic lymphadenectomy or sacrocolpopexy amongst others. Robotic assistance in gynaecology is thus feasible. Like conventional laparoscopic surgery, it allows decreased blood loss and morbidity as well as shorter hospital stay, as compared to laparotomy. It might indeed allow many surgical teams to perform minimally invasive surgical procedures which they were not used to performing by laparoscopy. Randomized prospective studies are needed to define its indications more precisely. Besides, its medico-financial impact should be evaluated too.

Staple line leaks after sleeve gastrectomy are dreaded complications. Many surgeons routinely perform an intraoperative leak test (IOLT) despite little evidence to validate the reliability, clinical benefit, and safety of this procedure. To determine the efficacy of IOLT and if routine use has any benefit over selective use. Eight teaching hospitals, including private, university, and military facilities. A multicenter, retrospective analysis over a 5-year period. The efficacy of the IOLT for identifying unsuspected staple line defects and for predicting postoperative leaks was evaluated. An anonymous survey was also collected reflecting surgeons' practices and beliefs regarding IOLT. From January 2010 through December 2014, 4284 patients underwent sleeve gastrectomy. Of these, 37 patients (.9%) developed a postoperative leak, and 2376 patients (55%) received an IOLT. Only 2 patients (0.08%) had a positive finding. Subsequently, 21 patients with a negative IOLT developed a leak. IOLT demonstrated a sensitivity of only 8.7%. There was a nonsignificant trend toward increased leak rates when an IOLT was performed versus when IOLT was not performed. Leak rates were not statistically different between centers that routinely perform IOLT versus those that selectively perform IOLT. Routine IOLT had very poor sensitivity and was negative in 91% of patients who later developed postoperative leaks. The use of IOLT was not associated with a decrease in the incidence of postoperative leaks, and routine IOLT had no benefit over selective leak testing. IOLT should not be used as a quality indicator or "best practice" for bariatric surgery. Published by Elsevier Inc.

To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients.

Distal radioulnar joint injuries

Full Text Available Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint , forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments.The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.

Rectal prolapse is defined as the protrusion of the rectal wall through the anal canal; with a prevalence of less than 0.5%. The most frequent symptoms include pain, incomplete defecation sensation with blood and mucus, fecal incontinence and/or constipation. The surgical approach can be perineal or abdominal with the tendency for minimal invasion. Robot-assisted procedures are a novel option that offer technique advantages over open or laparoscopic approaches. 67 year-old female, who presented with rectal prolapse, posterior to an episode of constipation, that required manual reduction, associated with transanal hemorrhage during defecation and occasional fecal incontinence. A RMI defecography was performed that reported complete rectal and uterine prolapse, and cystocele. A robotic assisted Frykman-Goldberg procedure wass performed. There are more than 100 surgical procedures for rectal prolapse treatment. We report the first robot assisted procedure in Mexico. Robotic assisted surgery has the same safety rate as laparoscopic surgery, with the advantages of better instrument mobility, no human hand tremor, better vision, and access to complicated and narrow areas. Robotic surgery as the surgical treatment is a feasible, safe and effective option, there is no difference in recurrence and function compared with laparoscopy. It facilitates the technique, improves nerve preservation and bleeding. Further clinical, prospective and randomized studies to compare the different minimal invasive approaches, their functional and long term results for this pathology are needed.

Type 1 diabetes requires intensive self-management to avoid acute and long-term health complications. In the past two decades, substantial advances in technology have enabled more effective and convenient self-management of type 1 diabetes. Although proximal technologies (eg, insulin pumps, continuous glucose monitors, closed-loop and artificial pancreas systems) have been the subject of frequent systematic and narrative reviews, distal technologies have received scant attention. Distal technologies refer to electronic systems designed to provide a service remotely and include heterogeneous systems such as telehealth, mobile health applications, game-based support, social platforms, and patient portals. In this Review, we summarise the empirical literature to provide current information about the effectiveness of available distal technologies to improve type 1 diabetes management. We also discuss privacy, ethics, and regulatory considerations, issues of global adoption, knowledge gaps in distal technology, and recommendations for future directions.

Abstract Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm2/m2 for women and 40.8 cm2/m2 for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover, sarcopenia is independently associated with overall and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. PMID:27043677

Poor nutrition and weight loss are important factors contributing to poor quality of life (QOL) after gastrectomy in patients with gastric cancer. Ghrelin is a hormone produced by the stomach that, plays a role in appetite increase and fat storage. The present study aims to clarify the location of ghrelin mRNA in the stomach, changes in blood ghrelin concentrations after gastrectomy and whether or not they are associated with the reconstruction method in patients with gastric cancer. We collected seven normal mucosa samples from different parts of six totally resected stomachs with gastric cancer. We extracted RNA from the normal mucosa, synthesized cDNA from total RNA (1 μg), and then quantified ghrelin mRNA using quantitative real-time polymerase chain reaction (Q-PCR). Ghrelin blood concentrations were measured using enzyme-linked immunosorbent assay (ELISA) kits in 74 patients with gastric cancer (total gastrectomy (TG), n=23; distal gastrectomy (DG), n=30; proximal gastrectomy (PG), n=11; pylorus preserving gastrectomy (PPG), n=10). In order, the ghrelin gene was expressed most frequently in the gastric body, followed by the fornix, cardia, antrum and pylorus ring. Blood ghrelin concentrations after surgery similarly changed in all groups. The average blood ghrelin concentrations were significantly higher in the DG and PPG groups than in the TG group on postoperative days (POD) 1, 7, 30, 90 and 180. However, blood ghrelin concentrations did not significantly differ between the DG and TG groups on POD 270 and 360. Cells that produce ghrelin are supposed to be located mostly in the fundic gland of the stomach. We speculate that the production of ghrelin from other organs increases from around nine months after total gastrectomy. Therefore, evaluating the nutritional status and the weight of patients at nine months after total gastrectomy is important to help these patients improve their QOL.

van der Goot et al. (2014) proposed that distal, deictic communication indexed the appreciation of the psychological state of a common ground between a signaler and a receiver. In their study, great apes did not signal distally, which they construed as evidence for the human uniqueness of a sense of common ground. This study exposed 166 chimpanzees to food and an experimenter, at an angular displacement, to ask, "Do chimpanzees display distal communication?" Apes were categorized as (a) proximal or (b) distal signalers on each of four trials. The number of chimpanzees who communicated proximally did not statistically differ from the number who signaled distally. Therefore, contrary to the claim by van der Goot et al., apes do communicate distally. © 2015 The Authors. Child Development © 2015 Society for Research in Child Development, Inc.

Robotic surgery was developed in response to the limitations and drawbacks of laparoscopic surgery. Since 1997 when the first robotic procedure was performed various papers pointed the advantages of robotic-assisted laparoscopic surgery, this technique is now a reality and it will probably become the surgery of the future. The aim of this paper is to present our preliminary experience with the three-arms "da Vinci S surgical system", to assess the feasibility of this technique in various abdominal and thoracic procedures and to point out the advantages of the robotic approach for each type of procedure. Between 18 January 2008 and 18 January 2009 153 patients (66 men and 87 women; mean age 48,02 years, range 6 to 84 years) underwent robotic-assisted surgical procedures in our institution; we performed 129 abdominal and 24 thoracic procedures, as follows: one cholecystectomy, 14 myotomies with Dor fundoplication, one gastroenteroanastomosis for unresectable antral gastric cancer, one transthoracic esophagectomy, 14 gastrectomies, one polypectomy through gastrotomy, 22 splenectomies,7 partial spleen resections, 22 thymectomy, 6 Nissen fundoplications, one Toupet fundoplication, one choledocho-duodeno-anastomosis, one drainage for pancreatic abscess, one distal pancreatectomy, one hepatic cyst fenestration, 7 hepatic resections, 29 colonic and rectal resections, 5 adrenalectomies, 12 total radical hysterectomies and pelvic lymphadenectomy, 3 hysterectomies with bilateral adnexectomy for uterine fibroma, one unilateral adnexectomy, and 2 cases of cervico-mediastinal goitre resection. 147 procedures were robotics completed , whereas 6 procedures were converted to open surgery due to the extent of the lesion. Average operating room time was 171 minutes (range 60 to 600 minutes, Median length of stay was 8,6 days (range 2 to 48 days). One system malfunctions was registered. Post-operatory complications occurred in 14 cases. There were no deaths. Our preliminary experience

In nongrowing patients with mild skeletal Class-III malocclusion, premolar extraction or molar distalization in the lower arch can be done as a part of camouflage treatment. Temporary anchorage devices are widely used for this purpose because they do not produce undesirable reciprocal effects and do not depend on the patient′s cooperation. However, most reported cases in this regard have used interradicular miniscrews in the mandibular arch and these have a risk of failure as they can loosen ...

Full Text Available Introduction: Hypersplenism is a common complication of portal hypertension. Cytopenia in hypersplenism is predominantly caused by splenomegaly. Distal splenorenal shunt (Warren with partial spleen resection is an original surgical technique that regulates cytopenia by reduction of the enlarged spleen. Objective. The aim of our study was to present the advantages of distal splenorenal shunt (Warren with partial spleen resection comparing morbidity and mortality in a group of patients treated by distal splenorenal shunt with partial spleen resection with a group of patients treated only by a distal splenorenal shunt. Method. From 1995 to 2003, 41 patients with portal hypertension were surgically treated due to hypersplenism and oesophageal varices. The first group consisted of 20 patients (11 male, mean age 42.3 years who were treated by distal splenorenal shunt with partial spleen resection. The second group consisted of 21 patients (13 male, mean age 49.4 years that were treated by distal splenorenal shunt only. All patients underwent endoscopy and assessment of oesophageal varices. The size of the spleen was evaluated by ultrasound, CT or by scintigraphy. Angiography was performed in all patients. The platelet and white blood cell count and haemoglobin level were registered. Postoperatively, we noted blood transfusion, complications and total hospital stay. Follow-up period was 12 months, with first checkup after one month. Results In the first group, only one patient had splenomegaly postoperatively (5%, while in the second group there were 13 patients with splenomegaly (68%. Before surgery, the mean platelet count in the first group was 51.6±18.3x109/l, to 118.6±25.4x109/l postoperatively. The mean platelet count in the second group was 67.6±22.8x109/l, to 87.8±32.1x109/l postoperatively. Concerning postoperative splenomegaly, statistically significant difference was noted between the first and the second group (p<0.05. Comparing the

Sleeve gastrectomy (SG) has known a spectacular rise worldwide during the last decade. The absence of digestive anastomosis simplifies the surgical technique, reducing anastomosis-related complications such as fistula, stricture and marginal ulcer. Furthermore, the respect for digestive continuity preserves the functions of pylorus, that regulates gastric emptying, and duodenum, where calcium, B vitamins and iron are absorbed. Despite the multiple advantages, SG also has specific complications such as bleeding, stenosis, portal thrombosis and leak. The staple line leak at the oesophagogastric junction is the most feared complication and its prevention remains difficult, as the involved mechanisms have been only partially elucidated. Its management is long and requires a multidisciplinary technical platform including Intensive Care Unit, digestive endoscopy and interventional radiology as well as a specialised surgeon. The aim of this review is to explain in detail the perioperative complications of SG, their prevention and treatment, referring to the most recent available literature.

Hiatal hernia (HH) is common in the bariatric population. Its presence imposes various degrees of difficulty in performing laparoscopic sleeve gastrectomy (LSG). Preoperative upper gastrointestinal evaluation consists of fluoroscopic and or endoscopic studies OBJECTIVES: To evaluate the efficacy of routine, preoperative barium swallow in identifying HH in patients undergoing LSG, and determine if such foreknowledge changes operative and immediate postoperative course regarding operative time, intraoperative adverse events, and length of hospital stay (LOS). In addition, to quantify HH prevalence in these patients and correlate preoperative patient characteristics with its presence. High-volume bariatric practice in a private hospital in Israel METHODS: Retrospective analysis of prospectively collected data between October 2010 and March 2015: anthropometrics, co-morbidities, previous barium swallow, preoperative HH workup (type and result), operative and immediate postoperative course. Primary LSG was performed in 2417 patients. The overall prevalence of HH was 7.3%. Preoperative diagnosis of gastroesophageal reflux disease and female gender were independent risk factors for HH presence. Operative times were significantly longer when HH was concomitantly repaired but "foreknowledge" thereof did not assist in shortening this time. Looking for an HH that was suggested in preoperative upper gastrointestinal evaluation slightly prolonged surgery. LOS was not changed in a significant fashion by HH presence and repair, whether suspected or incidentally found. Routine, pre-LSG barium swallow does not seem to offer an advantage over selective intraoperative hiatal exploration, in the discovery and management of HH. Conversely, when preoperative workup yields a false-positive result, surgery is slightly prolonged. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc.

The aim of this study is to present a new upper molar distalization appliance called Cise distalizer designed as intraoral device supported with orthodontic mini screw for upper permanent molar distalization. The new appliance consists of eight main components. In order to understand the optimum force level, the appliance under static loading is tested by using strain gage measurement techniques. Results show that one of the open coils produces approximately 300 gr distalization force. Cise distalizer can provide totally 600 gr distalization force. This range of force level is enough for distalization of upper first and second molar teeth.

Is there any occurrence of hidden (occult) endometriotic lesions in normal peritoneum of women with and without visible endometriosis? We detected a slightly higher occurrence of occult microscopic endometriosis (OME) in normal peritoneum of women with visible endometriosis than in control women. Based on a small number of cases, the concept of invisible microscopic endometriosis in visually normal peritoneum has been reported for more than a decade but there is controversy regarding their tissue activity and clinical significance. This case-controlled research study was conducted with prospectively collected normal peritoneal samples from 151 women with and 62 women without visible endometriosis. Normal peritoneal biopsy specimens from different pelvic sites of were collected during laparoscopy. A histological search of all peritoneal biopsy specimens for the detection of invisible endometriosis was done by immunoreaction to Ber-EP4 (epithelial cell marker), CD10 (stromal cell marker) and Calretinin (mesothelial cell marker). Tissue expression of estrogen/progesterone receptors (ER/PR) and cell proliferation marker, Ki-67, was performed by immunohistochemistry to identify tissue activity. Three different patterns of OME were detected based on (I) the presence of typical gland/stroma, (II) reactive hyperplastic change of endometrioid epithelial cells with surrounding stroma and (III) single-layered epithelium-lined cystic lesions with surrounding stroma. A higher tendency toward the occurrence of OME was found in women with visible endometriosis (15.2%, 23/151) compared with control women (6.4%, 4/62) (P = 0.06, χ(2) test). The epithelial cells and/or stromal cells of OME lesions were immunoreactive to Ber-EP4 and CD10 but not reactive to Calretinin. ER and PR expression was observed in all patterns of OME lesions. Ki-67 index was significantly higher in pattern I/II OME lesions than in pattern III OME lesions (Pendometriosis due to the presence of adhesions in

The application of robotic-assisted surgery offers EndoWrist instruments and 3-D visualization of the operative field, which are improvements over traditional laparoscopy. The results of the few studies published so far have shown that living donor nephrectomy using the robot-assisted technique is safe, feasible, and offers advantages to patients. Since November 2009, 16 patients have undergone robotic-assisted living donor nephrectomy at our Institute. Patients were divided into two groups according to the surgical technique adopted for the procedure: Group A, hand-assisted robotic nephrectomy (eight patients); Group B, totally robotic nephrectomy (eight patients). Intra-operative bleeding was similar in the two groups (90 vs 100 mL for Group A and B, respectively). Median warm ischemia time was significantly shorter in Group A (2.3 vs 5.1 min for Group A and B, respectively, P-value = 0.05). Switching to the open procedure was never required. Median operative time was not significantly longer in Group A than Group B (275 min vs 250 min, respectively). Robotic assisted living kidney recovery is a safe and effective procedure. Considering the overall technical, clinical, and feasibility aspects of living kidney donation, we believe that the robotic assisted technique is the method of choice for surgeon's comfort and donors' safety.

Surgical resection is currently the only treatment with the potential for long-term survival and cure of pancreatic cancer. Surgical resection is provided as distal pancreatectomy for cancers of the body and tail of the pancreas. It can be performed by laparoscopic or open surgery. In operations on other organs, laparoscopic surgery has been shown to reduce complications and length of hospital stay as compared with open surgery. However, concerns remain about the safety of laparoscopic distal pancreatectomy compared with open distal pancreatectomy in terms of postoperative complications and oncological clearance. To assess the benefits and harms of laparoscopic distal pancreatectomy versus open distal pancreatectomy for people undergoing distal pancreatectomy for pancreatic ductal adenocarcinoma of the body or tail of the pancreas, or both. We used search strategies to search the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded and trials registers until June 2015 to identify randomised controlled trials (RCTs) and non-randomised studies. We also searched the reference lists of included trials to identify additional studies. We considered for inclusion in the review RCTs and non-randomised studies comparing laparoscopic versus open distal pancreatectomy in patients with resectable pancreatic cancer, irrespective of language, blinding or publication status.. Two review authors independently identified trials and independently extracted data. We calculated odds ratios (ORs), mean differences (MDs) or hazard ratios (HRs) along with 95% confidence intervals (CIs) using both fixed-effect and random-effects models with RevMan 5 on the basis of intention-to-treat analysis when possible. We found no RCTs on this topic. We included in this review 12 non-randomised studies that compared laparoscopic versus open distal pancreatectomy (1576 participants: 394 underwent laparoscopic distal pancreatectomy and 1182

We describe the successful removal of a pelvic contraceptive coil in a symptomatic 46-year-old patient who had Essure devices for four years, using a combined hysteroscopy-laparoscopy-fluoroscopy approach. Following normal hysteroscopy, at laparoscopy the right Essure implant was disrupted and its outer nitinol coil had perforated the fallopian tube. However, the inner rod (containing polyethylene terephthalate) had migrated to an extrapelvic location, near the proximal colon. In contrast, the left implant was situated within the corresponding tube. Intraoperative fluoroscopy was used to confirm complete removal of the device, which was further verified by postoperative computed tomography. The patient's condition improved after surgery and she continues to do well. This is the first report to describe this technique in managing Essure complications remote from time of insertion. Our case highlights the value and limitations of preoperative and intraoperative imaging to map Essure fragment location before surgery.

AIM To evaluate the risks of medical conditions, evaluate gastric sleeve narrowing, and assess hydrostatic balloon dilatation to treat dysphagia after vertical sleeve gastrectomy (VSG). METHODS VSG is being performed more frequently worldwide as a treatment for medically-complicated obesity, and dysphagia is common post-operatively. We hypothesize that post-operative dysphagia is related to underlying medical conditions or narrowing of the gastric sleeve. This is a retrospective, single institution study of consecutive patients who underwent sleeve gastrectomy from 2013 to 2015. Patients with previous bariatric procedures were excluded. Narrowing of a gastric sleeve includes: inability to pass a 9.6 mm gastroscope due to stenosis or sharp angulation or spiral hindering its passage. RESULTS Of 400 consecutive patients, 352 are included; the prevalence of dysphagia is 22.7%; 33 patients (9.3%) have narrowing of the sleeve with 25 (7.1%) having sharp angulation or a spiral while 8 (2.3%) have a stenosis. All 33 patients underwent balloon dilatation of the gastric sleeve and dysphagia resolved in 13 patients (39%); 10 patients (30%) noted resolution of dysphagia after two additional dilatations. In a multivariate model, medical conditions associated with post-operative dysphagia include diabetes mellitus, symptoms of esophageal reflux, a low whole blood thiamine level, hypothyroidism, use of non-steroidal anti-inflammatory drugs, and use of opioids. CONCLUSION Narrowing of the gastric sleeve and gastric sleeve stenosis are common after VSG. Endoscopic balloon dilatations of the gastric sleeve resolves dysphagia in 69% of patients. PMID:28058017

Robot-assisted surgery overcomes some of the limitations of traditional laparoscopic surgery. We present our experience and lessons learned in two surgical units dedicated to gastro-esophageal surgery. From June 2009 to January 2013, we performed 130 robot-assisted gastroesophageal procedures, including Nissen fundoplication (29), paraesophageal hernia repair (18), redo for failed antireflux surgery (11), esophagectomy (19), subtotal (5) or wedge (4) gastrectomy, Heller myotomy for achalasia (22), gastric bypass for morbid obesity (12), thoracoscopic leiomyomectomy (4), Morgagni hernia repair (3), lower-third esophageal diverticulectomy (1) and two diagnostic procedures. There were 80 men and 50 women with a median age of 54 years (interquartile range: 46-65). Ten patients (7.7 %) had severe postoperative complications: eight after esophagectomy (three leaks-two cervical and one thoracic-managed conservatively), one stapler failure, one chylothorax, one case of gastric migration to the thorax, one case of biliary peritonitis, and one patient with a transient ventricular dyskinesia. One redo procedure needed reoperation because of port-site bleeding, and one patient died of pulmonary complications after a giant paraesophageal hernia repair; 30-day mortality was, therefore, 0.8 %. There were six elective and one forced conversions (hemorrhage), so total conversion was 5.4 %. Median length of stay was 4 days (IQ range 3-7). Robot-assisted gastroesophageal surgery is feasible and safe, and may be applied to most common procedures. It seems of particular value for Heller myotomy, large paraesophageal hernias, redo antireflux surgery, transhiatal dissection, and hand-sewn intrathoracic anastomosis.

Laparoscopic sleeve gastrectomy evolved as a primary bariatric procedure with little information on its nutritional effects. Our objective was to assess the longer term micronutrient and vitamin status after laparoscopic sleeve gastrectomy at a university hospital. Measurements of ferritin, iron, total iron binding capacity, hemoglobin, hematocrit, parathyroid hormone, albumin, calcium, magnesium, phosphorus, zinc, folate, and vitamins A, B1, B12, and D were obtained at baseline and 1, 3, and 5 years after surgery. Two-sample t tests with multiple adjusted comparisons and Fisher's exact test were used to determine deficiency. A total of 82 patients (67% women), with a mean age of 46.4 years and a baseline body mass index 55.7 kg/m2 were included in the present study (35 at 1, 27 at 3, and 30 at 5 years postoperatively). The percentage of excess body mass index loss was 58.5% at year 1 in 35 patients, 63.1% at year 3 in 27 patients, and 46.1% at year 5 in 30 patients. The parathyroid hormone level decreased from 75.0 to 49.6 ng/mL in year 1 to 40.7 ng/mL in year 3. The year 5 levels increased to 99.6 ng/mL. The mean vitamin D level increased from 23.6 ng/mL to 35.0, 32.1 and 34.8 at years 1, 3, and 5 (P = .05 for baseline to year 1). The vitamin D level was less than normal in 42% of the patients at year 5. After normalization from baseline, by year 5, parathyroid hormone had increased in 58.3% of patients. At year 5, vitamin B1 was less than normal in 30.8% of patients, and hemoglobin and hematocrit were less than normal in for 28.6% and 25% of patients, respectively. Finally, 28.9% of patients reported taking supplements in year 1, 42.9% in year 3, and 63.3% in year 5. The other variables were not significantly different. Laparoscopic sleeve gastrectomy resulted in health improvements through year 3. At year 5, the nutrient levels had reverted toward the baseline values. These observations provide focus for necessary clinical monitoring. Copyright © 2012 American
