    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.

    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.

    The aim of this study was to clarify the role of simultaneous combined diagnostic approach using laparoscopy and hysteroscopy in the evaluation of female infertility. In a retrospective study, 360 infertile women underwent complete fertility evaluation. All the patients were examined by simultaneous combined laparoscopy and hysteroscopy as a part of the routine infertility evaluation. Laparoscopy and hysteroscopy were successful in 360 patients. Bilateral tubes were blocked in 18 (5%) and unilateral tubal occlusion were in 30 (8,33%) of patients. Pelvic adhesions were revealed in 40 (11,11%), and myomas in 42 (11,65%) out of that 31 (8,6%) were revealed by laparoscopy and 11 (3,05%) by hysteroscopy. Endometrial polyps were revealed in 26 (7,22%) and Syndrome Asherman in 3(0,83%) of patients. Uterine anomaly was found in 19 (5,27%) of cases and out of that septate uterus in 7 (37,15%), bicornuate uterus in 5 (26,31%), arcuate uterus in 4 (21,26%) and uterus unicornu cum cornu rudimentario in 3 (15,27%) of uterine anomalies. Endometriosis was found in 51 (14,16%), dermoid cysts in 8 (2,22%) and in 16 (4,44%) functional cysts of patients. Also, Fitz-Hugh- Curtis syndrome was revealed in 23 (6,11%) of our patients. Laparoscopy and hysteroscopy play very important role as diagnostic tools in the infertility women. Combined diagnostic simultaneous laparoscopy and hysteroscopy should be performed in all infertile patients before the treatment. PMID:18318671

    To assess the clinical value of the diagnostic laparoscopy in choosing treatment strategies for patients with gastric cancer. Retrospective analysis was performed on clinical and pathological data collected from 2 023 patients undergoing gastric cancer surgery in the Zhongshan Hospital of Fudan University from 2009 to 2014. All the patients were diagnosed as gastric cancer by endoscopic biopsy and staged by imaging examination before surgery. During the diagnostic laparoscopy procedure, a small periumbilical incision was made and a pneumoperitoneum with CO 2 under 10-15 mmHg was established through a port. A 10 mm trocar was put in, and the camera was inserted. Two 5 mm trocars were put in two ports which located in midclavicular line two fingers under the left and right costal margin and then the instruments were inserted. A thorough inspection included ascites, the abdominal cavity, liver, diaphragm, spleen, greater omentum, colon, small intestine, mesentery, adnexa (female) and pelvic floor. If the tumor located at the posterior part of the stomach, the gastrocolic ligament was opened in order to look for carcinomatosis in the omental bursa. The accuracy rate of diagnostic laparoscopy in diagnosing adjacent organ invasion and intra-abdominal metastasis was calculated, and the rate of adjusting treatment plans after diagnostic laparoscopy was also calculated. There were 52.7%(1 067/2 023) of patients underwent diagnostic laparoscopy. The accuracy rate of diagnostic laparoscopy in evaluating adjacent organ invasion and intra-abdominal metastasis were 98.3%(1 049/1 067) and 98.1%(1 047/1 067) respectively. Besides, 14 patients with stage T4b and 32 with intra-abdominal metastasis, which were missed by imaging examination, were diagnosed by diagnostic laparoscopy. The treatment plans of 9.3% (99/1 067) of patients were changed after diagnostic laparoscopy, and 65 (6.1%) cases of non-therapeutic laparotomy were avoided. However, 18 cases of adjacent organ invasion

    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.

    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.

    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. PMID:29470527

    Surgical resection is the only curative treatment for pancreatic and periampullary cancer, but many patients undergo unnecessary laparotomy because tumours can be understaged by computerised tomography (CT). A recent Cochrane review found diagnostic laparoscopy can decrease unnecessary laparotomy. We compared the cost-effectiveness of diagnostic laparoscopy prior to laparotomy versus direct laparotomy in patients with pancreatic and periampullary cancer with resectable disease based on CT scanning. Model based cost-utility analysis estimating mean costs and quality-adjusted life years (QALYs) per patient from the perspective of the UK National Health Service. A decision tree model was constructed using probabilities, outcomes and cost data from published sources. One-way and probabilistic sensitivity analyses were undertaken. When laparotomy following diagnostic laparoscopy occurred in a subsequent admission, diagnostic laparoscopy incurred similar mean costs per patient to direct laparotomy (£7470 versus £7480); diagnostic laparoscopy costs (£995) were offset by avoiding unnecessary laparotomy costs. Diagnostic laparoscopy produced significantly more mean QALYs per patient than direct laparotomy (0.346 versus 0.337). Results were sensitive to the accuracy of diagnostic laparoscopy and the probability that disease was unresectable. Diagnostic laparoscopy had 63 to 66% probability of being cost-effective at a maximum willingness to pay for a QALY of £20 000 to £30 000. When laparotomy was undertaken in the same admission as diagnostic laparoscopy the mean cost per patient of diagnostic laparoscopy increased to £8224. Diagnostic laparoscopy prior to laparotomy in patients with CT-resectable cancer appears to be cost-effective in pancreatic cancer (but not in periampullary cancer), when laparotomy following diagnostic laparoscopy occurs in a subsequent admission.

    Stab wounds in the left thoracoabdominal region may cause diaphragmatic injury. The aim of the present study was to determine incidence of diaphragmatic injury and role of diagnostic laparoscopy in detection of injury in patients with left thoracoabdominal stab wound. Total of 81 patients (75 male, 6 female; mean age 27.5±9.8 years; range 14 to 60 years) who presented with left thoracoabdominal stab wound between April 2009 and September 2014 were evaluated. Laparotomy was performed on patients who had hemodynamic instability, signs of peritonitis, or organ evisceration. Remaining patients were followed conservatively. After 48 hours, diagnostic laparoscopy was performed on patients without laparotomy indication to examine the left diaphragm for injury. Follow-up and treatment findings were prospectively evaluated. Thirteen patients underwent laparotomy while diagnostic laparoscopy was performed on remaining 68 patients. Left diaphragmatic injury was observed in 19 patients (23.5%) in the study group. Four injuries were diagnosed by laparotomy and 15 were diagnosed by laparoscopy. Presence of hemopneumothorax did not yield difference in incidence of diaphragmatic injury (p=0.131). No significant difference was detected in terms of diaphragmatic injury with respect to entry site of stab wound in the thoracoabdominal region (p=0.929). It is important to evaluate the diaphragm in left thoracoabdominal stab injuries, and diagnostic laparoscopy is still the safest and most feasible method.

    Laparoscopic techniques have evolved, allowing increased capabilities within most subspecialties of general surgery, but have failed to gain traction managing injured patients. We hypothesized that laparoscopy is effective in the diagnosis and treatment of penetrating abdominal injuries. We retrospectively reviewed patients undergoing abdominal exploration following penetrating trauma at our Level 1 trauma center during a 6-year period from January 1, 2008, to December 31, 2013. Demographic and resuscitation data were obtained from our trauma registry. Charts were reviewed for operative details, hospital course, and complications. Hospital length of stay (LOS) and complications were primary end points. Patients were classified as having nontherapeutic diagnostic laparoscopy (DL), nontherapeutic diagnostic celiotomy (DC), therapeutic laparoscopy (TL), or therapeutic celiotomy (TC). TL patients were case-matched 2:1 with TC patients having similar intra-abdominal injuries. A total of 518 patients, including 281 patients (55%) with stab wounds and 237 patients (45%) with gunshot wounds, were identified. Celiotomy was performed in 380 patients (73%), laparoscopy in 138 (27%), with 44 (32%) converted to celiotomy. Nontherapeutic explorations were compared including 70 DLs and 46 DCs with similar injury severity. LOS was shorter in DLs compared with DCs (1 day vs. 4 days, p < 0.001). There were no missed injuries. Therapeutic explorations were compared by matching all TL patients 2:1 to TC patients with similar type and severity of injuries. Twenty-four patients underwent TL compared with 48 TC patients in the case matched group. LOS was shorter in the TL group than in the TC group (4 days vs. 2 days, p < 0.001). Wound infections were more common with open exploration (10.4% vs. 0%, p = 0.002), and more patients developed ileus or small bowel obstruction after open exploration (9.4% vs. 1.1%, p = 0.018). Laparoscopy is safe and accurate in penetrating abdominal injuries

    To evaluate the cost-effectiveness of a diagnostic laparoscopy prior to primary cytoreductive surgery to prevent futile primary cytoreductive surgery (i.e. leaving >1cm residual disease) in patients suspected of advanced stage ovarian cancer. An economic analysis was conducted alongside a randomized controlled trial in which patients suspected of advanced stage ovarian cancer who qualified for primary cytoreductive surgery were randomized to either laparoscopy or primary cytoreductive surgery. Direct medical costs from a health care perspective over a 6-month time horizon were analyzed. Health outcomes were expressed in quality-adjusted life-years (QALYs) and utility was based on patient's response to the EQ-5D questionnaires. We primarily focused on direct medical costs based on Dutch standard prices. We studied 201 patients, of whom 102 were randomized to laparoscopy and 99 to primary cytoreductive surgery. No significant difference in QALYs (utility=0.01; 95% CI 0.006 to 0.02) was observed. Laparoscopy reduced the number of futile laparotomies from 39% to 10%, while its costs were € 1400 per intervention, making the overall costs of both strategies comparable (difference € -80 per patient (95% CI -470 to 300)). Findings were consistent across various sensitivity analyses. In patients with suspected advanced stage ovarian cancer, a diagnostic laparoscopy reduced the number of futile laparotomies, without increasing total direct medical health care costs, or adversely affecting complications or quality of life.

    This study was designed to evaluate the prevalence, morbidity, and prognostic impact of port-site metastasis (PSM) in patients with epithelial ovarian cancer (EOC) undergoing laparoscopy before subsequent primary debulking surgery (PDS). All consecutive patients treated between 2000 and 2014, who had a laparoscopy followed by PDS, were extracted from our prospectively maintained database. All patients with histological examination of port-sites were included in this unicentric exploratory analysis. A total of 250 (25.5 %) of 982 patients with EOC underwent laparoscopy before PDS. Port-site resection was performed in those 214 (85.6 %) patients in whom a complete or almost complete resection with residuals ≤1 cm was achieved. Median interval between laparoscopy and PDS was 25 days. PSM was detected in 100 of 214 patients (46.7 %). Risk factors for PSM were higher tumor stage (odds ratio [OR] 13.5, 95 % confidence interval [CI] 2.9-62.0, p = 0.04), positive lymph node status (OR 3.0, 95 % CI 1.3-6.7, p = 0.009), and ascites >500 mL (OR 3.9, 95 % CI 1.5-10.0, p = 0.005). Wound healing disorders and postoperative morbidity were significantly higher in patients with PSM (Clavien-Dindo Classification grade 3-5: 41.0 vs. 14.9 %, p laparoscopy in EOC patients is considerably high. PSM had no impact on survival; however, PSM were associated with more postoperative complications and a higher surgical treatment burden. This should be balanced with the expected benefit when laparoscopy is considered for the management of EOC.

    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.

    Laparoscopy has a great role in early and effective diagnosis and treatment of ectopic pregnancy. This study was carried out to evaluate the feasibility and role of laparoscopy in diagnosis and treatment of ectopic pregnancy. This is a prospective observational study conducted in the Department of Obstetrics and Gynaecology, Kathmandu Medical College Teaching Hospital from April 2009 to March 2011. All the women who underwent laparoscopy for ectopic pregnancy or diagnosed as ectopic pregnancy during laparoscopy done for other diagnosis were included. Data were collected by interviewing patients, operating surgeons, reviewing charts and operative notes and following up patients. There were 42 cases of ectopic pregnancy during study period, of whom 16 (38.1%) underwent laparoscopy. Preoperative diagnosis of ectopic pregnancy was confirmed clinically in 6 (37.5%) patients, who underwent laparoscopy as an operative procedure. In the remaining 6 (37.5%), laparoscopy was performed as a diagnostic procedure as clinical diagnosis was doubtful; two cases of negative laparoscopy was noted. Incidental diagnosis of ectopic pregnancy was made in another 4 (25%) patients who had undergone laparoscopy for other pre operative diagnosis. All the patients were surgically managed by laparoscopy without converting it to laparotomy. There were no intraoperative or postoperative complications except for primary port infection in few (25%). Therefore, laparoscopy has a significant role in the diagnosis of ectopic pregnancy and operative laparoscopy is a safe approach with minimal complications.

    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.

    Objectives Laparoscopy is recommended to detect radiographically occult metastases in patients with pancreatic cancer before curative resection. This study was conducted to test the hypothesis that diagnostic laparoscopy (DL) is cost-effective in patients undergoing curative resection with or without neoadjuvant therapy (NAT). Methods Decision tree modelling compared routine DL with exploratory laparotomy (ExLap) at the time of curative resection in resectable cancer treated with surgery first, (SF) and borderline resectable cancer treated with NAT. Costs (US$) from the payer's perspective, quality-adjusted life months (QALMs) and incremental cost-effectiveness ratios (ICERs) were calculated. Base case estimates and multi-way sensitivity analyses were performed. Willingness to pay (WtP) was US$4166/QALM (or US$50 000/quality-adjusted life year). Results Base case costs were US$34 921 for ExLap and US$33 442 for DL in SF patients, and US$39 633 for ExLap and US$39 713 for DL in NAT patients. Routine DL is the dominant (preferred) strategy in both treatment types: it allows for cost reductions of US$10 695/QALM in SF and US$4158/QALM in NAT patients. Conclusions The present analysis supports the cost-effectiveness of routine DL before curative resection in pancreatic cancer patients treated with either SF or NAT. PMID:25123702

    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.

    Surgical resection is the only potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Laparoscopy can detect metastases not visualised on CT scanning, enabling better assessment of the spread of cancer (staging of cancer). This is an update to a previous Cochrane Review published in 2013 evaluating the role of diagnostic laparoscopy in assessing the resectability with curative intent in people with pancreatic and periampullary cancer. To determine the diagnostic accuracy of diagnostic laparoscopy performed as an add-on test to CT scanning in the assessment of curative resectability in pancreatic and periampullary cancer. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, EMBASE via OvidSP (from inception to 15 May 2016), and Science Citation Index Expanded (from 1980 to 15 May 2016). We included diagnostic accuracy studies of diagnostic laparoscopy in people with potentially resectable pancreatic and periampullary cancer on CT scan, where confirmation of liver or peritoneal involvement was by histopathological examination of suspicious (liver or peritoneal) lesions obtained at diagnostic laparoscopy or laparotomy. We accepted any criteria of resectability used in the studies. We included studies irrespective of language, publication status, or study design (prospective or retrospective). We excluded case-control studies. Two review authors independently performed data extraction and quality assessment using the QUADAS-2 tool. The specificity of diagnostic laparoscopy in all studies was 1 because there were no false positives since laparoscopy and the reference standard are one and the same if histological examination after diagnostic laparoscopy is positive. The sensitivities were therefore meta-analysed using a univariate random-effects logistic

    Which reproductive endocrine changes are attributed exclusively to laparoscopic ovarian drilling in polycystic ovarian syndrome (PCOS)? Laser evaporation-specific endocrine effects were the prevention of an immediate increase in inhibin B and a sustained decrease in testosterone, androstenedione and anti-Müllarian hormone (AMH). All ovarian drilling procedures result in reproductive endocrine changes. It is not known which of these changes are the result of ovarian drilling and which are related to the surgery per se. This prospective controlled study was performed at an outpatient academic fertility clinic. Between 2007 and 2010, a total of 21 oligo- or amenorrheic PCOS patients were included. Included were oligo- or amenorrheic PCOS patients with all three of the Rotterdam criteria and luteinizing hormone (LH) >6.5 U/l. All PCOS patients had an indication for diagnostic surgery due to subfertility. There were 12 PCOS patients who chose to undergo ovarian laser evaporation (CO2 laser, 25 W, 20 times/ovary) and 9 PCOS who chose a diagnostic laparoscopy only (controls). Reproductive endocrinology was measured before, and until 5 days after, surgery, and four gonadotrophin-releasing hormone (GnRH) 'double pulse' tests were included. The main outcome measures were changes in reproductive endocrinology and pituitary sensitivity/priming to GnRH after laser evaporation compared with diagnostic laparoscopy only. In the first hours after surgery, both groups showed an increase in LH, follicle stimulating hormone, estrogen and a decrease in testosterone, androstenedione, AMH and insulin growth factor-1 (P evaporation or laparoscopy only. The limitations of this study are the short follow-up period and the relatively small groups. The strength of this study is the integrally measured endocrine profiles in combination with an optimal control group of PCOS patients undergoing diagnostic laparoscopy only. Interestingly, most of the immediate endocrine changes after laser

    Successful cases have shown that conversion surgery after chemotherapy improves the prognosis of advanced gastric cancer. However, it is necessary to carefully select patients who have no unresectable factors prior to surgery. We recently reported that diagnostic laparoscopy with photodynamic diagnosis using oral 5-aminolevulinic acid (ALA-PDD) is a promising tool for diagnosing early peritoneal metastasis in gastric cancer. We herein evaluated the usefulness of this technique for detecting peritoneal metastases of advanced gastric cancer after chemotherapy. Diagnostic laparoscopy using sequential white light (WL) and ALA-PDD observations was performed in 38 patients with advanced gastric cancer after chemotherapy. The sensitivity of ALA-PDD for detecting peritoneal disease was compared with that of WL. The relationship between the state of peritoneal metastasis assessed by ALA-PDD and a cytological examination of the peritoneal fluid was evaluated. Twelve of the 38 patients (32 %) were diagnosed with peritoneal metastases by conventional laparoscopy. However, laparoscopy with ALA-PDD detected peritoneal metastases in 4 (11 %) of the 26 remaining patients. Three of these 4 patients had negative cytological results from the evaluation of the peritoneal fluid. Diagnostic laparoscopy using ALA-PDD is a useful technique for detecting metastases and determining treatment strategies to select patients with advanced gastric cancer who have received chemotherapy.

    IntroductionThe surgical treatment of the acute neonatal abdomen still poses a challenge in pediatric surgery. Various underlying etiologies require different surgical procedures. Until today the role of laparoscopy in the surgical treatment of the acute neonatal abdomen is controversial. The aim of this study was to analyze our experiences with laparoscopy and to perform a review of the literature. Methods Retrospective, single-institution study including all term and preterm neonates initially undergoing laparoscopy due to an acute abdomen. Results Altogether, 17 neonates presenting with an acute neonatal abdomen initially underwent laparoscopy. Unnecessary laparotomy could be avoided in 9 of 17 (53%) neonates. After diagnostic laparoscopy, 2 patients did not require any further surgical intervention. Eight neonates presented midgut atresia intraoperatively, 5 of them underwent laparoscopic-assisted correction. Successful laparoscopic derotation of an acute volvulus (n = 1) and laparoscopic appendectomy (n = 1) could be performed. Conversion to open surgery was necessary in 8 neonates (47%) due to creation of a stoma (n = 5), multiple intestinal bands causing poor visualization (n = 2), and bowel necrosis (n = 1). Conclusions Laparoscopy is a useful diagnostic tool to evaluate the need for further surgical intervention in the acute neonatal abdomen and enables immediate surgical treatment of acute volvulus, appendicitis, or intestinal atresia. In case of conversion to laparotomy, precise localization of the incision is guaranteed. Minimization of the surgical trauma and avoidance of unnecessary laparotomy are the most important benefits of the minimal-invasive approach for the critically ill neonate. © The Author(s) 2016.

    Despite improved preoperative imaging techniques, patients with incurable or unresectable gastric cancer are still subjected to non-therapeutic laparotomy. Diagnostic laparoscopy (DL) has been advocated by some to be essential in decision-making in gastric cancer. We aimed to identify and synthesize findings on the value of DL for patients with gastric cancer, in this era of improved preoperative imaging. Electronic literature searches were conducted using Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from January 1, 1998 to December 31, 2009. We calculated the change in management and avoidance of laparotomy based on the addition of DL and laparoscopic ultrasound (LUS). The accuracy, agreement (kappa), sensitivity, and specificity of DL in assessing tumor extent, nodal involvement, and the presence of metastases with respect to the gold standard (pathology) were also calculated. Twenty-one articles were included. DL showed moderate to substantial agreement with final pathology for T stage, but only fair agreement for N stage. For M staging, DL had an overall accuracy, sensitivity, and specificity ranging from 85-98.9%, 64.3-94%, and 80-100%, respectively. The use of DL altered treatment in 8.5-59.6% of cases, avoiding laparotomy in 8.5-43.8% of cases. LUS provided additional benefit in 5.8-7.2% of cases. Despite evolving preoperative imaging techniques, diagnostic laparoscopy continues to be of substantial value in staging patients with gastric cancer and in avoiding unnecessary laparotomy. The current data support DL for all patients with advanced gastric cancer.

    Full Text Available Objective: To determine the role of diagnostic hysterolaparoscopy in the evaluation of infertility in tertiary care centres. Materials and Methods: This retrospective study was conducted at two tertiary care centres (the infertility clinics of Sriram Chandra Bhanj Medical College and Prachi hospital at Cuttack, Odisha throughout the year in 2008. Women aged 20-40 years with normal hormone profile without male factor infertility were included. Results: Out of 300 cases, 206 (69% patients had primary infertility. While laparoscopy detected abnormalities in 34% of the cases, significant hysteroscopy findings were noted in 18% of cases. Together, diagnostic hysterolaparoscopy detected abnormalities in 26% of the infertile patients in both groups. While the most common laparoscopic abnormality was endometriosis (14% and adnexal adhesion (12% in primary and secondary infertile patients, respectively, hysteroscopy found intrauterine septum as the most common abnormality in both groups. Conclusions: Hysterolaparoscopy is an effective diagnostic tool for evaluation of certain significant and correctable tubo-peritoneal and intrauterine pathologies like peritoneal endometriosis, adnexal adhesions, and subseptate uterus, which are usually missed by other imaging modalities.

    Abstract Objectives  To explore women's views about the risks and benefits of diagnostic laparoscopy in the investigation of chronic pelvic pain, including how much information it is thought appropriate to give about three specific risks: death, major complications and the chance that the procedure would have an inconclusive result. Design  A qualitative analysis of semi‐structured, audio‐taped interviews with 20 women about their experiences of undergoing a diagnostic laparoscopy in a day surgery unit. Interviews were conducted 3–6 months after the procedure. Results  All the women who were interviewed were aware that diagnostic laparoscopy carried risks, including the small risk of death associated with general anaesthesia. One‐third of respondents said that they had initially been reluctant to discuss the risks of the procedure in general terms. However, when specific examples of complications and risks were introduced all but one of the respondents reported that they would have liked to discuss these at the time that the decision to have the operation was made. Women maintained that the information was needed to make an informed decision about whether to have the operation, to help them understand and cope should things go wrong and in order to make appropriate plans to cover contingencies. Most were surprised to hear that the procedure is frequently inconclusive and thought that this information should be made clear to women contemplating a laparoscopy. Conclusions  Women undergoing diagnostic laparoscopy for the investigation of chronic pelvic pain wish to be given full and accurate information about complication rates such as bowel perforation, what to expect during their recovery, and the chances of finding a cause for their pain. Although they may not want to dwell on the risk of death, they do need to be informed about the specific risks associated with the procedure in order to make a balanced decision. PMID:12460219

    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 diagnosticslaparoscopy.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.

    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.

    Abstract Background Staging laparoscopy can visualize peritoneal and liver metastases in pancreatic cancer otherwise undetectable by preoperative imaging. However, false-negative rates may be as high as 18%–26%. The aim of the present study was to improve detection of metastatic pancreatic cancer with the use of fluorescence laparoscopy (FL) in a nude-mouse model with the tumors expressing green fluorescent protein (GFP). Methods The carcinomatosis mouse model of human pancreatic cancer was established by intraperitoneal injections of green fluorescent protein-expressing MiaPaca-2 human pancreatic cancer cells into 6-week-old female athymic mice. Two weeks later, mice underwent diagnostic laparoscopy. Laparoscopy was performed first under standard brightfield lighting, followed by fluorescent lighting. The number of metastatic foci identified within the four quadrants of the peritoneal cavity was recorded. After laparoscopy, the animals were sacrificed, opened, and imaged with the OV-100 Small Animal Imaging system as a positive control to identify metastasis. Tumors were collected and processed for histologic review. Results FL enabled visualization of pancreatic cancer metastatic foci not visualized with standard brightfield laparoscopy (BL). Under FL, in 1 representative mouse, 26 separate micrometastatic lesions were identified. In contrast, only very large tumors were seen using BL. Use of the OV-100 images, as positive controls, confirmed the presence of tumor foci. FL thus allowed identification and exact localization of submillimeter tumor foci. Such small-sized tumor foci were not distinguished from surrounding tissue under BL. All malignant lesions were histologically confirmed. Conclusions The use of FL enables the identification of tumor foci that cannot be seen with standard laparoscopy. The technology described in this report has important potential for the clinical development of FL. PMID:21699431

    Purpose To investigate whether initial diagnostic laparoscopy can prevent futile primary cytoreductive surgery (PCS) by identifying patients with advanced-stage ovarian cancer in whom > 1 cm of residual disease will be left after PCS. Patients and Methods This multicenter, randomized controlled trial was undertaken within eight gynecologic cancer centers in the Netherlands. Patients with suspected advanced-stage ovarian cancer who qualified for PCS were eligible. Participating patients were randomly assigned to either laparoscopy or PCS. Laparoscopy was used to guide selection of primary treatment: either primary surgery or neoadjuvant chemotherapy followed by interval surgery. The primary outcome was futile laparotomy, defined as a PCS with residual disease of > 1 cm. Primary analyses were performed according to the intention-to-treat principle. Results Between May 2011 and February 2015, 201 participants were included, of whom 102 were assigned to diagnostic laparoscopy and 99 to primary surgery. In the laparoscopy group, 63 (62%) of 102 patients underwent PCS versus 93 (94%) of 99 patients in the primary surgery group. Futile laparotomy occurred in 10 (10%) of 102 patients in the laparoscopy group versus 39 (39%) of 99 patients in the primary surgery group (relative risk, 0.25; 95% CI, 0.13 to 0.47; P laparoscopy group, three (3%) of 102 patients underwent both primary and interval surgery compared with 28 (28%) of 99 patients in the primary surgery group ( P laparoscopy reduced the number of futile laparotomies in patients with suspected advanced-stage ovarian cancer. In women with a plan for PCS, these data suggest that performance of diagnostic laparoscopy first is reasonable and that if cytoreduction to < 1 cm of residual disease seems feasible, to proceed with PCS.

    To compare robotic-assisted laparoscopy with conventional laparoscopy for treatment of advanced stage endometriosis insofar as operative time, estimated blood loss, complication rate, and length of hospital stay. Retrospective cohort study (Canadian Task Force classification II2). All procedures were performed by one surgeon between January 2004 and July 2012. Data was collected via chart review. Tertiary referral center for treatment of endometriosis. Four hundred twenty women with advanced endometriosis. Fertility-sparing surgery to treat advanced endometriosis, either via conventional or robotic-assisted laparoscopy. Patient demographic data, operative time, estimated blood loss, complication rate, and length of hospital stay were compared between the 2 groups. Two hundred seventy-three patients underwent conventional laparoscopy and 147 patients underwent robotic-assisted laparoscopy for fertility-sparing treatment of advanced stage endometriosis. Patients in both groups had similar characteristics insofar as age, body mass index, and previous abdominal surgeries. There were no significant differences in blood loss or complication rate between the 2 groups. Mean operative time in the conventional laparoscopy group was 135 minutes (range, 115-156 minutes), and in the robotic-assisted laparoscopy group was 196 minutes (range, 185-209 minutes), with a mean difference in operative time of 61 minutes (p laparoscopy group. Most patients who underwent conventional laparoscopy were discharged to home on the day of surgery. Of 273 patients in the conventional laparoscopy group, only 63 remained in the hospital overnight, and all 147 patients in the robotic-assisted laparoscopy group were discharged on postoperative day 1. Conventional laparoscopy and robotic-assisted laparoscopy are excellent methods for treatment of advanced stages of endometriosis. However, use of the robotic platform may increase operative time and might also be associated with longer hospital stay

    Right iliac fossa (RIF) pain is one of the most common presenting complaints faced by general surgeons in the emergency department. Correct diagnosis and appropriate surgical intervention can often pose a challenge. A 12-year-old girl presented to the emergency department with a four day history of initially central acute abdominal pain, now localised in the RIF. During laparoscopy, the following findings were made: macroscopically dilated appendix, right and left gonads at the internal opening of the inguinal canal, empty pelvis with a rudimentary uterus on the right side. No evidence of fallopian tubes or connection of uterus to the vagina and broad based, non-inflamed Meckel's diverticulum. An incidental diagnosis of complete androgen insensitivity syndrome was made. Androgen insensitivity syndrome (AIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriate normal concentrations of androgens. This case report highlights the advantage of laparoscopy as a diagnostic and treatment tool in a twelve year old girl with multiple intra-abdominal findings. While the ultimate diagnosis responsible for her symptom of RIF pain was acute appendicitis, the additional diagnosis of CAIS and incidental Meckel's would have otherwise likely gone undetected.

    Laparoscopy has been proposed for the management of recurrent hepatolithiasis, but no comparative study of its relative efficacy versus laparotomy has been performed, and the patient selection criteria for laparoscopy are not clear. This study aimed to investigate the therapeutic effect of laparoscopy versus laparotomy for repeated hepatolithiasis and to highlight how to select patients best suited for laparoscopy. We performed a cohort study of 94 patients who underwent laparotomy or laparoscopy for recurrent hepatolithiasis between January 2010 and May 2014. The clinical data of 53 patients who underwent open biliary exploration (laparotomy group) and 41 patients who underwent laparoscopic biliary exploration (laparoscopy group) for recurrent hepatolithiasis were retrospectively analyzed and compared. Intestinal adhesions to the porta hepatis occurred in 62 (66%) patients. There was no difference in operating time between the two groups. In comparing the laparoscopic group versus the laparotomy group, the intraoperative blood loss was less (P = .001), the incidence of postoperative ascites (9.8 vs. 30.2%, P = .016) and/or pleural effusion (7.3 vs. 28.3%, P = .010) was lower, and the stone clearance rates were comparable. Wound morbidity appeared peculiarly in 15 (28.3%) patients among the laparotomy group. The postoperative hospital stay in the laparoscopy group was shorter than that in the laparotomy group (P = .000). Laparoscopy is a safe and effective treatment for recurrent hepatolithiasis patients who are scheduled for bile duct exploration.

    Technologic advances and superior survival with mechanical circulatory support (MCS) have led to an expanding population that develops intraabdominal conditions requiring intervention. Whether laparoscopy can be performed without detrimental effects on hemodynamics and device function is not well described. Effects of laparoscopy performed on MCS were retrospectively assessed. Intraoperative hemodynamics and device function were compared with the same time interval 24 hours prior to surgery using intrapatient paired t tests. Outcomes included survival, transfusion, thromboembolic events, and infection. Twelve patients with ventricular assist devices or total artificial hearts underwent laparoscopy from 2012 to 2014. Median follow-up was 116 days. Operations included cholecystectomy, diagnostic laparoscopy, gastrojejunostomy, and gastrostomy. There were no differences between preoperative and intraoperative mean arterial pressure, heart rate, and inotrope or vasopressor requirements (P > .05). Device fill volume, flow, rate, and power were unchanged (P > .05), whereas pulsatility index decreased by 0.2 (95% confidence interval, 0.03, 0.36) with laparoscopy (P = .03). All intraoperative fluctuations in hemodynamics and device function improved with reduction of pneumoperitoneum, adjusting device speed, or pharmacologic support. There were no operative mortalities. Thirty-day survival and survival to discharge were 75% and 50%, respectively. Despite antiplatelet therapy and preoperative international normalization ratio of 2.2 ± 0.9, there were no re-operations for bleeding, and 50% did not require transfusion. Two patients with recent cardiac surgery had thromboembolic events: one stroke and one device thrombus. None had postoperative bacteremia or driveline infection. Laparoscopy can be performed on MCS with low morbidity and mortality and minimal perturbations in hemodynamics and device function.

    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.

    The aim of this study was to evaluate laparoscopic versus open surgery for suspected appendicitis during pregnancy. A hospital-based retrospective review of 65 consecutive pregnant patients who underwent surgery for suspected appendicitis from 1999 to 2008 was performed. Significance was determined by Pearson's chi(2) test, Fisher's exact test, Mann-Whitney test, and Kruskal-Wallis test. Of the 65 patients, 48 cases were laparoscopic and 17 open. Use of the laparoscopic versus open approach was significantly increased in the first (100% vs. 0%, p appendicitis. While methodological limitations preclude a definitive recommendation, laparoscopy appears to be a safe, feasible, and efficacious approach for pregnant patients with presumed acute appendicitis. We conclude that it is likely not the surgical approach but the underlying diagnosis combined with maternal factors that determine the risk for pregnancy complications. A benefit of laparoscopy is the diagnostic ability to identify other intra-abdominal pathology which may mimic appendicitis and harbor pregnancy risks.

    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)

    The vermiform appendix has no constant position and the data on the variations in its position are limited. The aim of this study was to determine the frequency of the various positions of the appendix at laparoscopy. Patients undergoing emergency or elective laparoscopy at a university teaching hospital between April and September 2004 were studied prospectively. The positions of the appendix and the caecum were determined after insertion of the laparoscope, prior to any other procedure and the relative frequencies calculated. A total of 303 (102 males and 201 females) patients with a median age of 52 years (range 18-93 years) were studied. An emergency appendicectomy was performed in 67 patients, 49 had a diagnostic laparoscopy, 179 underwent a laparoscopic cholecystectomy and eight had other procedures. The caecum was at McBurney's point in 245 (80.9%) patients, pelvic in 45 (14.9%) and high lying in 13 (4.3%). The appendix was pelvic in 155 (51.2%) patients, pre-ileal in 9 (3.0%), para-caecal in 11 (3.6%), post-ileal in 67 (22.1%) and retrocaecal in 61 (20.1%) patients. Contrary to the common belief the appendix is more often found in the pelvic rather than the retrocaecal position. There is also considerable variation in the position of the caecum.

    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.

    Peritoneal entry (PE) during transanal endoscopic microsurgery (TEM) for tumors of the upper rectum is not an uncommon complication. The suture line of the rectal defect performed for PE is not devoid of leaks. Diagnostic laparoscopy after PE enables visualization and testing of the suture line. Here, we report the outcome of patients undergoing laparoscopy for PE following TEM. Data pertaining to patients undergoing laparoscopy for PE following TEM between 2004 and 2013 were retrospectively collected. One hundred and forty-one TEM procedures were performed, and 19 (13 %) with PE were included. The mean age was 68.1 ± 10.6 years, mean distance from the anal verge 12.5 ± 2 cm, and mean tumor size 2 cm. Lesions were located in the lateral wall (n = 14), anteriorly (n = 4), and posteriorly (n = 1). Indications for TEM were: adenoma (n = 13), indeterminate margins after polypectomy (n = 4, a submucosal lesion (n = 1), and a T1N0 adenocarcinoma (n = 1). In all patients, the rectal wall defect was closed primarily. Twelve patients underwent additional laparoscopy and suture line leak testing. In one patient, a small leak was detected which was repaired laparoscopically. In another, a hematoma of the suture line was observed and a drain was left in place. The mean operative time was 109 min (range 80-135 min) for TEM and 33 min (range 22-45 min) for laparoscopy. A diverting ileostomy was fashioned in one patient on postoperative day 3 after TEM without laparoscopy. No other major complications were observed. Laparoscopy after PE during TEM permits visualization and testing of the suture line. It is not associated with increased morbidity, and it may increase the safety of TEM.

    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)

    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.

    Introduction  Abdominal injuries are common, costly, deadly, and a source of considerable uncertainty in pediatric trauma. In some circumstances, laparoscopy offers a diagnostic and therapeutic alternative with less morbidity than standard exploration, and more certainty than most imaging. In this study, we review our experience with laparoscopic exploration for trauma. We hypothesized that laparoscopy could be employed effectively in stable blunt or penetrating trauma patients in whom diagnostic uncertainty was unresolved by imaging. Patients and Methods  A retrospective review of the trauma database identified all children admitted to our Level I pediatric trauma center between January 1, 2000, and December 31, 2012, requiring surgical abdominal exploration. The utilization of laparoscopy and laparotomy was charted over the 13-year period. Negative laparoscopies and laparotomies and nontherapeutic laparoscopies and laparotomies were examined to investigate clinical scenarios in which laparotomy might have been avoided. Statistical analyses were performed using descriptive statistics, simple linear regression analysis, and Mann-Whitney U test ( p  laparoscopy. In 13 patients (34.2%), laparoscopic exploration ruled out injuries. In nine patients (23.7%), laparoscopy identified an injury for which no surgical intervention was necessary. In nine patients (23.7%), an injury was repaired laparoscopically. In seven cases (18.4%), the identified injury required conversion to laparotomy. There were no missed injuries. In the laparotomy group, a less invasive approach could have yielded the same information in 8.7% of patients. Laparoscopy was more likely to be used after a qualitative change in institutional minimally invasive surgical capability. Conclusion  Laparoscopy reliably resolves diagnostic uncertainty in selected cases of pediatric abdominal blunt and penetrating trauma. In a hemodynamically stable patient with a concerning exam and inconclusive imaging

RESULTS: Pancreatic core biopsies and diagnostic steroid trial were not preoperatively performed in any of the patients. Based on preoperative data, ICDC diagnosed...... 6 patients (20%) as having type 1 AIP and 24 (80%) as probable AIP. Assuming all patients had responded to a steroid trial preoperatively, ICDC would have diagnosed 8 patients (27%) as having type 1 AIP, 4 (13%) as type 2 AIP, 10 as AIP-not otherwise specified (33%), and 8 (27%) as probable AIP....... In the hypothetical situation, 7 of 8 type 1 AIP patients and 3 of 3 type 2 AIP patients would have been classified into the correct subtype of AIP. CONCLUSIONS: A steroid trial enhances the possibility of correctly diagnosing AIP by ICDC despite the lack of histology. However, some patients cannot be diagnosed...

    Background and Objectives: The aim of this study is to evaluate the prevalence of intraabdominal adhesions to the umbilicus following gynecologic laparoscopy through an umbilical incision. Methods: A retrospective review was performed of all gynecologic laparoscopic procedures in a private practice setting to identify patients with a repeat laparoscopy who had a history of a previous laparoscopy through an umbilical incision. Patients with a history of other surgeries were excluded. All repeat laparoscopies used a left upper quadrant entry technique where the abdominal cavity was surveyed for adhesions. We also reviewed adverse events attributable to the left upper quadrant entry approach. Results: We identified 151 patients who underwent a second laparoscopy and had a previous umbilical scar. Thirty-two of the 151 (21.2%) patients with a history of a laparoscopy had evidence of adhesions to the umbilical undersurface. No adverse events or injuries were attributed to the left upper quadrant entry technique. Conclusions: Adhesions to the umbilical undersurface occur in 21.2% of patients who have undergone a prior laparoscopy through an umbilical incision. For this reason, we recommend an alternate location for entry in patients with an umbilical scar from a previous laparoscopy. PMID:17651555

    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.

    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)

    To compare perioperative details among patients who underwent gynecologic surgery between traditional laparoscopy and three-dimensional laparoscopy. The present prospective non-randomized study enrolled all consecutive patients diagnosed with gynecologic pathology who underwent laparoscopic surgery at Reina Sofia Hospital, Cordoba, Spain between January 1 and April 30, 2014. Perioperative data, adverse events, and patient satisfaction were compared between patients who underwent treatment with two-dimensional and three-dimensional laparoscopic surgery techniques. The study enrolled 60 consecutive patients; 31 (52%) patients who underwent three-dimensional surgery and 29 (48%) who underwent traditional two-dimensional surgery. No significant differences were observed in the adverse-event rate, operating time, or perioperative parameters. A higher use of sealing devices was recorded among patients who underwent three-dimensional laparoscopy (P=0.021). No difference was recorded in patient satisfaction between the two patient groups. Although there was no impact on surgical outcomes, three-dimensional surgery could give a more accurate view of the surgical field. Performing three-dimensional surgery could be beneficial for more complex procedures although further comparative studies are required to investigate this hypothesis. © 2016 International Federation of Gynecology and Obstetrics.

    To evaluate the obstetric outcome, surgical morbidity, and pre-abdominal cerclage characteristics of women undergoing transabdominal cerclage (TAC) via laparotomy or laparoscopy. Prospective cohort study (Canadian Task Force classification II-2). University hospital. Between 2007 and 2014, 51 patients underwent laparoscopic abdominal cervical cerclage to treat cervical incompetence. These women were compared with a historical cohort of 18 patients who underwent the same procedure via laparotomy between 1995 and 2011. All of the women had a diagnosis of cervical incompetence based on previous obstetric history and/or a short or absent cervix. The fetal survival rate postcerclage was 100% in the laparotomy group (n = 30 pregnancies) and 98% in the laparoscopy group (n = 54 pregnancies). There were no perioperative pregnancy losses in either group. The median gestation age was 36.9 weeks (range: 35.0-37.3) in the laparotomy group and 37.0 weeks (range: 34.7-38.0) in the laparoscopy group. Complications were recorded in 4 (22%) cases from the laparotomy group and 1 (2%) of the laparoscopies; however, the types of complications might not be comparable between groups. There were no conversions to laparotomy in the laparoscopy group. Pre-TAC median gestational age in the laparotomy group was 24.0 weeks (range: 20.0-25.1) with 19 (57.6%) previous pregnancies occurring after transvaginal cervical cerclage placement. The corresponding laparoscopy pre-TAC median gestational age was 22.0 weeks (range 19.0-34.0) with 40 (40%) previous pregnancies having a transvaginal cerclage. Before the TAC, women in the laparotomy group had lost 25 babies, and 63 babies were lost in the laparoscopy group. After TAC, these numbers were 0 and 1. Our findings show that transabdominal cervical cerclage placed laparoscopically appears to be as effective as TAC placed via laparotomy. Neither approach was associated with serious or long-term complications. Because of this finding, the approach

    There are few reports about laparoscopic approach after liver transplantation (LT). The aim of this paper is to analyze in terms of feasibility and therapeutic effectiveness an initial experience with laparoscopy in patients who have had a liver transplantation. Laparoscopic procedures were divided into "early" and "late" laparoscopy. A total of 10 laparoscopic procedures after LT were performed in 9 patients: 3 early and 7 late. The early laparoscopic procedures were performed in 3 patients who had a torpid evolution in their liver transplant: 2 were diagnostic only and 1 was also therapeutic. There were no intraoperative events or conversions. We recorded 2 complications. In 7 patients a late laparoscopy was performed: 4 in the upper abdomen and 3 in the lower abdomen. Of the 4 in the upper abdomen, 3 were liver procedures and 1 was in the transverse colon, on the other side; in addition, 2 laparoscopic inguinal hernia repairs and 1 laparoscopic appendectomy also were performed. None of these 7 cases was converted, and there were no intraoperative events. The early postoperative period, in critically ill patients diagnostic and eventually therapeutic laparoscopy was feasible and effective in our cases. Late laparoscopy in the upper abdomen is difficult due to adhesions and adds to the risk of poor graft function, but was feasible for both diagnostic and therapeutic purposes. Late laparoscopy in the lower abdomen with good graft function has the same safety and efficacy as those performed on nontransplanted patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available The spectrum of laparoscopic surgery in children has undergone a dramatic evolution. Initially used as a diagnostic modality for many pediatric urologists, complex as well as reconstructive procedures are now being performed laparoscopically. Laparoscopic orchiopexy and nephrectomy are well established and are being performed at many centers. Laparoscopic partial nephrectomy, adrenalectomy, and dismembered pyeloplasty series have reported shortened hospital stays and operative times that are comparable to that of open techniques or are decreasing with experience. The initial experiences with laparoscopic ureteral reimplantation and laparoscopic-assisted bladder reconstructive surgery have been described, reporting encouraging results with regards to feasibility, hospital stay, and cosmetic outcome. This report will provide a directed review of the literature to establish the current indications for laparoscopy in pediatric urologic surgery.

    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. 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. 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. 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.

    Emergency laparoscopic surgery allows both the evaluation of acute abdominal pain and the treatment of many common acute abdominal disorders. This review critically evaluates the current evidence base for the use of laparoscopy, both diagnostic and interventional, in the emergency abdomen, and provides guidance for surgeons as to current best practise. Laparoscopic surgery is firmly established as the best intervention in acute appendicitis, acute cholecystitis and most gynaecological emergencies but requires further randomised controlled trials to definitively establish its role in other conditions.

    To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Preoperative localization of nonpalpable testes will aid in planning of the surgical management. We evaluate the efficacy of magnetic resonance imaging (MRI) as the preoperative study in the management of the nonpalpable testis in the laparoscopic era. From 1997 to 2001, a total of 30 MRI evaluation was performed for 30 patients with nonpalpable testis. When the imaging study demonstrated a viable testis in the inguinal region, the patient underwent inguinal orchiopexy. Diagnostic laparoscopy was performed for the patient whose testis was intraabdominal or could not be detected by imaging. Thirty-one testes from 30 patients were evaluated. The imaging studies showed 16 testes from 15 patients in the inguinal region. Fifteen testes were found in the inguinal region and one was intraabdominal during groin exploration. Four testes were pointed out to be intraabdominal by MRI and identified by laparoscopic examination. Eleven testes could not be detected by the imaging studies and they underwent laparoscopic examination. Two abdominal testes were identified. Nine patients underwent inguinal surgical exploration and had a diagnosis of inguinal vanishing testis. No gonadal tissue was identified in those specimens. The sensitivity and the specificity of our MRI studies in predicting the presence of nonpalpable testis were 90.5% and 100%, respectively. Inguinal undescended testes could be diagnosed accurately with MRI and laparoscopy was informative regarding the testis location in all cases. When no intraabdominal testis is identified laparoscopically in the patient whose testis can not be detected in the inguinal region by MRI, the testis is likely vanished. (author)

    Diagnosis of acute pancreatitis in dogs remains a significant challenge despite the development of advanced diagnostic methodologies. Visual inspection and pancreas biopsy using laparoscopy are generally considered to be procedures free of complications when conducted on healthy animals. However, the usefulness of laparoscopy for diagnosing acute pancreatitis has not been assessed. In the present study, the efficacy of laparoscopy for diagnosing acute pancreatitis in dogs was evaluated in animals with experimentally induced acute pancreatitis. Gross appearance of the pancreatic area was examined by laparoscopy to survey for the presence of edema, adhesions, effusion, pseudocysts, hemorrhage, and fat necrosis. Laparoscopic biopsy was performed and the histopathologic results were compared to those of pancreatic samples obtained during necropsy. The correlation between laparoscopy and histopathologic findings of the pancreas was evaluated. The presence of adhesions, effusion, and hemorrhage in the pancreatic area observed by laparoscopy significantly correlated with the histopathologic results (p pancreatitis in dogs.

    Objective To evaluate the benefit of staging laparoscopy in patients with gallbladder cancer and hilar cholangiocarcinoma. Summary Background Data In patients with extrahepatic biliary carcinoma, unresectable disease is often found at the time of exploration despite extensive preoperative evaluation, thus resulting in unnecessary laparotomy. Methods From October 1997 to May 2001, 100 patients with potentially resectable gallbladder cancer (n = 44) and hilar cholangiocarcinoma (n = 56) were prospectively evaluated. All patients underwent staging laparoscopy followed by laparotomy if the tumor appeared resectable. Surgical findings, resectability rate, length of stay, and operative time were analyzed. Results Patients underwent multiple preoperative imaging tests, including computed tomography scan, ultrasound, magnetic resonance cholangiopancreatography, and direct cholangiography. Laparoscopy identified unresectable disease in 35 of 100 patients. In the 65 patients undergoing open exploration, 34 were found to have unresectable disease. Therefore, the overall accuracy for detecting unresectable disease was 51%. There was no difference in the accuracy of laparoscopy between patients with gallbladder cancer and hilar cholangiocarcinoma. Laparoscopy detected the majority of patients with peritoneal or liver metastases but failed to detect all locally advanced tumors. In patients undergoing biopsy only, laparoscopic identification of unresectable disease significantly reduced operative time and length of stay compared with patients undergoing laparotomy. The yield of laparoscopy was 48% in patients with gallbladder cancer (56% in those who did not undergo previous cholecystectomy), but only 25% in patients with hilar cholangiocarcinoma. However, in patients with locally advanced but potentially resectable hilar cholangiocarcinoma, the yield of laparoscopy was greater, 36% (12/33, T2/T3 tumors) versus 9% (2/23, T1 tumors). Conclusions Laparoscopy identifies the majority

    If morbidity and mortality are to be reduced in patients with penetrating abdominal trauma, first priority goes to prompt and accurate determination of peritoneal penetration and identification of the need for surgery. In this setting, laparoscopy may have an important impact on the rate of negative or non-therapeutic laparotomies. We analyzed indications and patient selection criteria for laparoscopy in penetrating trauma along with outcomes. The analysis focused on identification of peritoneal penetration and injuries to the diaphragm, small intestine, and mesentery. Results from the early phase of laparoscopy were compared with those from recent decades with more advanced laparoscopic equipment and instruments and more experienced surgeons. A systematic review of the role of laparoscopy in penetrating abdominal trauma shows a sensitivity ranging from 66.7 to 100%, specificity from 33.3 to 100% and accuracy from 50 to 100%. Publications from the 1990s found trauma laparoscopy to be inadequate for detecting intestinal injuries and so to lead to missed injuries. Twenty-three of the 50 studies including the most recent ones report sensitivity, specificity, and accuracy of 100%. Laparoscopy is more cost effective than negative laparotomy. Laparoscopy can be performed safely and effectively on stable patients with penetrating abdominal trauma. The most important advantages are reduction of morbidity, accuracy in detecting diaphragmatic and intestinal injuries, and elimination of prolonged hospitalization for observation, so reducing the length of stay and increasing cost effectiveness.

    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.

    This article shows the experience in 61 patients with adnexal tumors studied from June 1988 to June 1994; the origin of the patients in private and semiprivate, to whom we practiced a diagnostic and operative laparoscopy (56/61) at the same time. The inclusion and exclusion criteria were determined by clinical history (past history, age, symptoms, size, etc.), vaginal ultrasonography scan (ascites, papillas, cyst's content, etc.), laboratory tests (Ca 125 in postmenopausal patients), the macroscopic assessment during the diagnostic laparoscopy, transoperative biopsy (19/61) was made in order to confirm the benign findings seen before laparoscopy; and the results were accordingly on the 61 cases. The cause of consult was infertility in 24/61; 18/61 were primary infertility; 6/61 were secondary infertility. We did 22 cystectomies and 2 oophorectomies; 10 of them became pregnant. 37 from 61 had pain, nine of this group we did an oophorectomy (2 by torsion, 3 had hemorrhagic cysts that were ruptured and 4 were residual ovary), the rest 28 we performed cystectomy with frank improvement of their symptoms. The postoperative diagnosis of the tumors were: luteomas 13/61; functional cysts 17/61, Hemorrhagic cysts 8/61; endometriomas 9/61; serous cystoadenoma 3/61; mucinous cystoadenoma 1/61; ovaric fibroma 1/61; mature cystic teratoma 2/61; residual ovaries 4/61; paraovaric cysts 2/61 and Morgagni's hydatide 1/61. It is concluded that if one follows all the correct parameters for the evaluation of adnexal tumors, the endoscopic procedure could be safe with the benefits of the laparoscopic procedure.

    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.

    Accurate staging can be a major problem in therapeutic planning of advanced abdominal malignancies. We experimentally combined conventional staging laparoscopy with aminolevulinic acid (ALA) induced fluorescence diagnosis (FD) to improve the detection of disseminated peritoneal tumors. Using different photosensitization times and ALA concentrations we evaluated the optimal fluorescence parameters for laparoscopic fluorescence diagnosis of intra abdominal tumor spread. In a rat tumor model we performed conventional and fluorescence laparoscopy to determine the increase of sensitivity gained by FD in terms of additionally detected lesions. After laparoscopic examination, the fluorescence emission from the tumors was spectrometically analyzed. Serum levels of ALA and PpIX were measured by HPLC to determine their systemic metabolism. Fluorescence staging laparoscopy was able to visualize even macroscopically occult neoplasms. Using 1.5 percent ALA solution and a photosensitization time of 4 hours as favorable parameters the diagnostic value of conventional staging laparoscopy was significantly improved: 35 percent of all malignant lesions were detected only by FD. Therefore, fluorescence laparoscopy suggest to be a highly promising preoperative staging tool requiring minimal technical and clinical expenditure. It provides the laparoscopist with a rapid and accurate technique to assess more thoroughly the full extent of malignant tumor growth in the abdominal cavity.

    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.

    To review laparoscopy in patients with disorders of sex development (DSD) in order to clarify its usefulness in diagnosis, devising subsequent therapeutic strategies and managing patients with various conditions. Between April 1992 and December 2012, 29 laparoscopic surgeries were performed in 25 DSD patients. Among them, ten were diagnostic laparoscopy including gonadal biopsy, and 19 were therapeutic laparoscopy. Surgical procedures and complications were evaluated. For diagnostic laparoscopy, laparoscopic gonadal biopsy was performed in three patients. Inspection, with or without open gonadal biopsy, was performed on four out of seven patients with 46XY DSD or mixed gonadal dysgenesis (MGD). Additional surgery was planned and performed based on diagnostic laparoscopic findings in six out of seven patients. In the three patients with ovotesticular DSD, the gonadal pathology was diagnosed as: testis/ovary in one, testis/ovotestis in one and ovary/ovotestis in one--this was from the laparoscopic inspection and/or gonadal biopsy. However, the final diagnoses were bilateral ovotestis in two patients and ovary/ovotestis in one patient. For therapeutic laparoscopy, surgical procedures were: gonadectomy in 17 patients (bilateral in 13, unilateral in three, partial in two); hysterectomy in two patients; orchiopexy in one; and sigmoid vaginoplasty in one patient (included multiple procedures). There were no severe perioperative complications. In the four patients with a history of diagnostic laparoscopy, no severe intra-abdominal adhesions that would disturb therapeutic laparoscopic surgery were observed. While diagnostic laparoscopy was helpful in devising a therapeutic surgical strategy in most of the patients with DSD who were suspected as having complex gonadal status or Müllerian duct derivatives, attention must be paid to precisely diagnosing the gonadal status in ovotesticular DSD. On the other hand, therapeutic laparoscopic surgeries were valuable procedures in

    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.

    From January 1981 till October 1991, 47 diagnostic laparoscopies were performed in 50 impalpable testicles. In total, 28 intra-abdominal testes were found. In 14 cases no testes were found, but a deferential duct and vessels were seen. In 7 cases the diagnosis of testicular agenesia was made. One laparoscopy was a technical failure. We bring our results of this safe and reliable procedure, and discuss our management. A review of treatment options for intra-abdominal testes is given.

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)

    To estimate the prevalence of genital tuberculosis in women with idiopathic chronic pelvic pain on laparoscopy, correlate laparoscopic findings with microbiological and histological diagnosis of tuberculosis and assess the response to anti tubercular treatment (ATT) in these cases. In a prospective cohort study, fifty women with idiopathic chronic pelvic pain were enrolled. Diagnostic laparoscopy was done in all women and fluid from pouch of Douglas and/or saline washings were sent for acid fast bacilli (AFB) smear, conventional and rapid culture and DNA polymerase chain reaction (PCR) analysis for diagnosis of genital TB. The results of these tests were analyzed and agreement with laparoscopy was assessed using Kappa statistics. Pain scores using visual analogue scale were compared before and after treatment. Pelvic pathology was present in 44 (88%) women of idiopathic chronic pelvic pain, with a 34% prevalence rate of genital tuberculosis. Pelvic inflammation was associated with positive peritoneal fluid PCR (n=4) and AFB culture (n=3). Acid fast bacilli PCR had substantial agreement (kappa statistics=0.716) with visual findings at laparoscopy. There was a significant reduction in pain scores after treatment. Genital tuberculosis contributes to one-third cases of chronic pelvic pain. Pelvic inflammation is an early feature of genital TB and peritoneal fluid PCR has the best co-relation with laparoscopic findings of genital tuberculosis.

    The aim of this study was to evaluate the effect of laparoscopy on patients with blunt hollow viscus and mesenteric injuries (BHVMIs). Hemodynamically stable patients with BHVMIs were diagnosed using computed tomography and serial examinations. Patients admitted from July 1, 1999 to June 30, 2006 underwent exploratory laparotomy (group A), and those admitted from January 1, 2007 to December 31, 2013 received laparoscopy (group B). There were 62 patients in group A, and 59 patients in group B. There were no significant differences in demographic characteristics, injury severity score, and injuries requiring surgical intervention between the groups (all, P > .05). Patients in group B had a shorter hospital stay (mean 11.0 vs 17.6 days, P laparoscopy to laparotomy in group B was 8.5%, compared with a 100% laparotomy rate in group A (P Laparoscopy is feasible and safe for hemodynamically stable patients with BHVMIs.

    This study aimed to identify the yield of staging laparoscopy with peritoneal lavage cytology for gastric cancer patients and to track it over time. The medical records of patients with gastric or gastroesophageal adenocarcinoma who underwent pretreatment staging laparoscopy at the authors' institution from 1995 to 2012 were reviewed. The yield of laparoscopy was defined as the proportion of patients who had positive findings on laparoscopy, including those with macroscopic carcinomatosis, positive cytology, or other clinically important findings. To compare the yield of laparoscopy over time, the patients were divided into three 6-year ranges based on the date of diagnosis. Associations between clinicopathologic factors and peritoneal disease were examined using uni- and multivariate analyses. The study included 711 patients. Among these patients, 43.5 % had gastroesophageal junction tumors, 72.9 % had poorly differentiated adenocarcinoma, and 53 % had signet ring cell morphology. Endoscopic ultrasound had most commonly identified T3 (83.9 %) and N-positive (66.4 %) tumors. At laparoscopy, 148 (20.8 %) patients had been found to have macroscopic peritoneal carcinomatosis. Among 514 macroscopically negative patients who underwent peritoneal lavage cytologic analysis, 68 (13.2 %) had positive cytology results for malignancy. The total laparoscopy yield was 36 %, which did not change over time (p = 0.58). Multivariate analysis demonstrated that positive cytology or carcinomatosis was associated with poorly differentiated histology, linitis plastica, and equivocal computed tomography findings. Laparoscopy remains a useful staging procedure to evaluate for peritoneal spread when treatment or surgery is considered, even with the current availability of high-quality imaging.

    Gallstone disease is one of the most common problems in the gastroenterology and is associated with significant morbidity. It may present as stones in the gallbladder (cholecystolithiasis) or in the common bile duct (choledocholithiasis). At the end of the 1980s laparoscopy was introduced and first laparoscopic cholecystectomy was performed in 1985. The laparoscopic technique for removing the gallbladder is the current treatment of choice, although indications for open surgery exist. To perform laparoscopic cholecystectomy as safe as possible multiple safety measures were developed. The gold standard for diagnosing and removing common bile duct stones is Endoscopic Retrograde Cholangiopancreatography (ERCP). The surgical treatment option for choledocholithiasis is laparoscopic cholecystectomy with common bile duct exploration. If experience is not available, than ERCP followed by elective cholecystectomy is by far the best therapeutic modality. The present review will discuss the use, benefits and drawbacks of laparoscopy in patients with cholecystolithiasis and choledocholithiasis. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Increased abdominal pressure may have a negative effect on intracranial pressure (ICP). Human data on the effects of laparoscopy on ICP are lacking. We retrospectively reviewed laparoscopic operations for ventriculoperitoneal shunt placement to determine the effect of insufflation on ICP. Nine patients underwent insufflation with carbon dioxide (CO(2)) at pressures ranging from 8 to 15 mm Hg and ICP measured through a ventricular catheter. We used a paired t test to compare ICP with insufflation and desufflation. Linear regression correlated insufflation pressure with ICP. The mean ICP increase with 15-mm Hg insufflation is 7.2 (95% CI, 5.4-9.1 [P pressure (P = .04). Maximum ICP recorded was 25 cm H(2)O. Intracranial pressure significantly increases with abdominal insufflation and correlates with laparoscopic insufflation pressure. The maximum ICP measured was a potentially dangerous 25 cm H(2)O. Laparoscopy should be used cautiously in patients with a baseline elevated ICP or head trauma.

    Aim: To evaluate the accuracy of water enema computed tomography (CT) for predicting the location of endometriosis in patients with contraindications to magnetic resonance imaging (MRI), focusing on rectosigmoid lesions and having laparoscopic and histological data as the reference standard. Materials and methods: Thirty-three women (mean age 33.4 ± 3.1 years) suspected of having deep pelvic endometriosis underwent 64-row CT and video laparoscopy within 4 weeks. Two radiologists blinded to the clinical data evaluated the CT images obtained after colonic retrograde distension using water as the contrast medium, and a comparison with laparoscopic and histological findings was performed. CT sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated. The radiation dose to patients was estimated. Cohen's weighted kappa (κ) test was used to evaluate the interobserver agreement. Results: In 23 out of 33 patients (69%) intestinal implants were found at surgery and pathological examinations. CT confirmed the diagnosis of rectosigmoid endometriosis in 20 out of 23 implants. Three nodules located on the proximal sigmoid colon (two serosal lesions and one infiltrating the muscularis layer) with a diameter of less than 1 cm were not diagnosed. CT sensitivity, specificity, PPV, NPV, and accuracy values were 87, 100, 100, 77, and 91%, respectively. The mean effective dose estimate was 6.30 ± 1.7 mSv. Almost perfect agreement between the two readers was found (k = 0.84). Conclusion: Water enema CT can play a role in the diagnosis of bowel endometriosis and represents another accurate potential tool for video laparoscopic approaches, especially in patients for whom MRI is contraindicated

    To compare intraoperative physiologic variables and post-operative pain associated with lift laparoscopy and conventional capnoperitoneum laparoscopy. Prospective randomized case controlled study. Healthy dogs (n = 30). Dogs having laparoscopic ovariohysterectomy were randomly assigned to lift laparoscopy (n = 14) or capnoperitoneum (16) laparoscopy. Physiologic variables measured intraoperatively were documented. Postoperatively, pain response was assessed in a blinded fashion using the short Glasgow pain scale and von Frey filament aesthesiometry. Lift laparoscopy was associated with less frequency of hypercapnia, required less anesthetic gas, and was not more time-consuming or painful than capnoperitoneum laparoscopy. Lift laparoscopy is a feasible alternative to capnoperitoneum laparoscopy, especially in dogs where pressurized capnoperitoneum is not desired. © Copyright 2014 by The American College of Veterinary Surgeons.

    Full Text Available The many benefits of laparoscopy, including smaller incision, reduced length of hospital stay and more rapid return to normal function, have seen its popularity grow in recent years. With concurrent improvements in non-surgical cancer management the importance of accurate staging is becoming increasingly important. There are two main applications of laparoscopic surgery in managing hepato-pancreatico-biliary (HPB malignancy: accurate staging of disease and resection. We aim to summarize the use of laparoscopy in these contexts. The role of staging laparoscopy has become routine in certain cancers, in particular T[2] staged, locally advanced gastric cancer, hilar cholangiocarcinoma and non-Hodgkin's lymphoma. For other cancers, in particular colorectal, laparoscopy has now become the gold standard management for resection such that there is no role for stand-alone staging laparoscopy. In HPB cancers, although staging laparoscopy may play a role, with ever improving radiology, its role remains controversial.

    AIM: To evaluate the safety and effectiveness of laparoscopy compared with laparotomy for diagnosing and treating small bowel injuries (SBIs) in a porcine model. METHODS: Twenty-eight female pigs were anesthetized and laid in the left recumbent position. The SBI model was established by shooting at the right lower quadrant of the abdomen. The pigs were then randomized into either the laparotomy group or the laparoscopy group. All pigs underwent routine exploratory laparotomy or laparoscopy to evaluate the abdominal injuries, particularly the types, sites, and numbers of SBIs. Traditional open surgery or therapeutic laparoscopy was then performed. All pigs were kept alive within the observational period (postoperative 72 h). The postoperative recovery of each pig was carefully observed. RESULTS: The vital signs of all pigs were stable within 1-2 h after shooting and none of the pigs died from gunshot wounds or SBIs immediately. The SBI model was successfully established in all pigs and definitively diagnosed with single or multiple SBIs either by exploratory laparotomy or laparoscopy. Compared with exploratory laparotomy, laparoscopy took a significantly longer time for diagnosis (41.27 ± 12.04 min vs 27.64 ± 13.32 min, P = 0.02), but the time for therapeutic laparoscopy was similar to that of open surgery. The length of incision was significantly reduced in the laparoscopy group compared with the laparotomy group (5.27 ± 1.86 cm vs 15.73 ± 1.06 cm, P surgery, both laparotomy and laparoscopy offered a definitive diagnosis with no missed injuries. Postoperative complications occurred in four cases (three following laparotomy and one following laparoscopy, P = 0.326). The average recovery period for bowel function, vital appearance, and food re-intake after laparoscopy was 10.36 ± 4.72 h, 14.91 ± 3.14 h, and 15.00 ± 7.11 h, respectively. All of these were significantly shorter than after laparotomy (21.27 ± 10.17 h, P = 0.004; 27.82 ± 9.61 h, P laparotomy

    Purpose To compare the relative merits among robotic surgery, laparoscopy, and laparotomy for patients with endometrial cancer by conducting a meta-analysis. Methods The MEDLINE, Embase, PubMed, Web of Science, and Cochrane Library databases were searched. Studies clearly documenting a comparison between robotic surgery and laparoscopy or between robotic surgery and laparotomy for endometrial cancer were selected. The outcome measures included operating time (OT), number of complications, length of hospital stay (LOHS), estimated blood loss (EBL), number of transfusions, total lymph nodes harvested (TLNH), and number of conversions. Pooled odds ratios and weighted mean differences with 95% confidence intervals were calculated using either a fixed-effects or random-effects model. Results Twenty-two studies were included in the meta-analysis. These studies involved a total of 4420 patients, 3403 of whom underwent both robotic surgery and laparoscopy and 1017 of whom underwent both robotic surgery and laparotomy. The EBL (p = 0.01) and number of conversions (p = 0.0008) were significantly lower and the number of complications (plaparoscopy. The OT, LOHS, number of transfusions, and TLNH showed no significant differences between robotic surgery and laparoscopy. The number of complications (plaparoscopy and laparotomy for patients with endometrial cancer. Robotic surgery is associated with significantly lower EBL than both laparoscopy and laparotomy; fewer conversions but more complications than laparoscopy; and shorter LOHS, fewer complications, and fewer transfusions but a longer OT than laparoscopy. Further studies are required. PMID:25259856

    We sought to develop a multiple biomarker approach for prediction of incident major adverse cardiac events (MACE; composite of cardiovascular death, myocardial infarction, and stroke) in patients referred for coronary angiography. In a 649-participant training cohort, predictors of MACE within 1 year were identified using least-angle regression; over 50 clinical variables and 109 biomarkers were analyzed. Predictive models were generated using least absolute shrinkage and selection operator with logistic regression. A score derived from the final model was developed and evaluated with a 278-patient validation set during a median of 3.6 years follow-up. The scoring system consisted of N-terminal pro B-type natriuretic peptide (NT-proBNP), kidney injury molecule-1, osteopontin, and tissue inhibitor of metalloproteinase-1; no clinical variables were retained in the predictive model. In the validation cohort, each biomarker improved model discrimination or calibration for MACE; the final model had an area under the curve (AUC) of 0.79 (p Time-to-first MACE was shorter in those with an elevated score (p <0.001); such risk extended to at least to 4 years. In conclusion, in a cohort of patients who underwent coronary angiography, we describe a novel multiple biomarker score for incident MACE within 1 year (NCT00842868). Copyright © 2017 Elsevier Inc.

    Minimally invasive surgery (MIS) has contributed significantly to patient care by reducing the morbidity associated with more invasive procedures. MIS procedures have become standard treatment for gallbladder disease and some abdominal malignancies. The imaging system has played a major role in the evolving field of minimally invasive surgery (MIS). The image need to have good resolution, large magnification, especially, the image need to have depth cue at the same time the image have no flicker and suit brightness. The video stereo-laparoscopy system can meet the demand of the doctors. This paper introduces the 3d video laparoscopy has those characteristic, field frequency: 100Hz, the depth space: 150mm, resolution: 10pl/mm. The work principle of the system is introduced in detail, and the optical system and time-division stereo-display system are described briefly in this paper. The system has focusing image lens, it can image on the CCD chip, the optical signal can change the video signal, and through A/D switch of the image processing system become the digital signal, then display the polarized image on the screen of the monitor through the liquid crystal shutters. The doctors with the polarized glasses can watch the 3D image without flicker of the tissue or organ. The 3D video laparoscope system has apply in the MIS field and praised by doctors. Contrast to the traditional 2D video laparoscopy system, it has some merit such as reducing the time of surgery, reducing the problem of surgery and the trained time.

    Preoperatively evaluating the resectability of pancreatobiliary cancers is difficult. The aim of this study was to investigate the benefit of staging laparoscopy in unresectable pancreatobiliary cancers. Between 2010 and 2013, 25 patients with pancreatobiliary cancers underwent staging laparoscopy after conventional tumor staging; they were compared with 10 patients who had unresectable or metastatic tumors that were found during laparotomy. Staging laparoscopy did not show unresectable factors in 11 patients, and resections were performed in these patients. Unresectable factors were found in other 14 patients who underwent staging laparoscopy. In these patients, chemotherapy was started after median postoperative day 3 (range, 2-10 days). This period was significantly longer in patients who received unnecessary laparotomy; chemotherapy was started after median postoperative day 11 (range, 6-15 days). These results suggest that staging laparoscopy, while avoiding laparotomy with unsuccessful resection, can lead to rapid induction of chemotherapy for unresectable pancreatobiliary cancers. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    The aim of this study is to verify if the surgical approach (laparoscopy/laparotomy/vaginal) in stage-I endometrial cancer treatment, may have effects on intra- and post-operative outcomes and on the patient's quality of life. The study group consisted of patients with histological diagnosis of type-I endometrial adenocarcinoma, stage-I. They were divided into three groups according to surgical approach chosen (laparotomic/laparoscopic/vaginal). Every patient answered a telephone health survey (SF-36) at 30 and 180 days post-surgery. Surgical-operating times, hospitalization length and short/long-term complications after surgery were also compared. The SF-36 survey revealed a better performance status in patients who underwent laparoscopy as compared to those who received laparotomy or vaginal surgery. We found significantly better results considering General Health, Physical Functioning, Role-Physical and Bodily Pain in the laparoscopy group after 30 and 180 days. Patients who underwent laparoscopy had significantly shorter hospitalization and less post-operative complications even if laparoscopy required significantly longer surgical-operating times compared to vaginal surgery. Our data confirm the superiority of the laparoscopic approach respect to the laparotomic and vaginal ones both in term of hospitalization length and post-operative complications.

    Background: 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. Methods: A descriptive, prospective case series was collected in the department of Paediatric surgery Mayo 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 SPSS17. Results: Out of 50 patients studies, 27/50 (54 percentage) were male, 23/50 (46 percentage) 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 percentage), reduced intensity of pain was gained in 12/50 (24 percentage) cases while 16 percentage (8/50) still complained of pain. Conclusions: 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. (author)

    The application of laser light and laparoscopy attenuates operative trauma owing to the use of small incisions for introducing the trochars necessary for conveying the surgical instruments and fiber optics which allow for precise cutting and coagulation of small vessels under control of the image on a TV monitor. The present, most remarkable development of laparoscopic surgery is due to the fascination of physicians and patients by this procedure. The method enables the physician to operate with great precision and to take advantage of the most recent attainments of electronics and laser technique, as well as of his own ability. The patients profit by attenuation of postoperative pain, limitation of the probability of infection, reduced blood loss, decreased number of postoperative complications, shortening of the hospitalization period, and rapid return to physical fitness and work.

    Synchronous gastrointestinal multiple primary cancers (SGMPC) is infrequent. This study aimed to investigate the feasibility and outcomes of laparoscopy-assisted combined resection for SGMPC. We retrospectively reviewed 16 cases of SGMPC underwent either open or laparoscopy-assisted combined resection in the Third Affiliated Hospital of Sun Yat-sen University from Jan. 2005 to Jan. 2014. Sixteen cases contained synchronous colon cancers (n = 10), gastric and rectal cancer (n = 5), gastric and duodenal cancer (n = 1). Either laparoscopy-assisted or open procedure was performed. Compared with the open group, the laparoscopy group presented less blood loss (77.1 ± 46.3 ml vs. 145.0 ± 75.9 ml, P = 0.047) and shorter incision length (5.2 ± 0.7 cm vs. 16.4 ± 1.9 cm, P = 0.000), while no differences in operative time (228.3 ± 38.8 min vs. 188.8 ± 47.7 min, P > 0.05) and postoperative hospital stay (10.0 ± 3.4 days vs. 12.0 ± 4.8 days, P > 0.05). Two cases of postoperative complications occurred in the open group and one case of incision infection occurred in the laparoscopy one. Upon follow-up, 2 cases of open group (50.0%) and 8 cases of laparoscopy group (66.7%) were under status of disease free survival. Laparoscopy-assisted combined resection for SGMPC is feasible, safe and effective. Copyright © 2015 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

    The rates of laparoscopic colectomy for colon cancer have steadily increased since its inception. Laparoscopic colectomy currently accounts for a third of colectomy procedures in the United States, but little is known regarding the spatial pattern of the utilization of laparoscopy for colon cancer. This study evaluated the utilization of laparoscopy for colon cancer at the neighborhood level in Ontario. Retrospective analysis of prospectively collected data was performed. This study was conducted at all hospitals in the province of Ontario. This population-based study included all patients aged ≥18 who received an elective colectomy for colon cancer from April 2008 until March 2012 in the province of Ontario. The primary outcome measure was the neighborhood rates of laparoscopy. Overall, 9,969 patients underwent surgery, and the cluster analysis identified 74 cold-spot neighborhoods, representing 1.8 million people, or 14% of the population. In the multivariate analysis, patients from rural neighborhoods were less than half as likely to receive laparoscopy, OR 0.44 (95% CI, 0.24-0.84; p = 0.012). Additionally, having a minimally invasive surgery fellowship training facility within the same administrative health region as the neighborhood made it more than 23 times as likely to be a hot spot, OR 25.88 (95% CI, 12.15-55.11; p laparoscopy. Patient case mix could affect laparoscopy use. This study identified an unequal utilization of laparoscopy for colon cancer within Ontario with rural neighborhoods experiencing low rates of laparoscopic colectomy, whereas neighborhoods in the same administrative region as minimally invasive surgery training centers experienced increased utilization. Further study into the causes of this variation in resource allocation is needed to identify ways to improve more efficient spread of knowledge and technical skills advancement.

    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 laparoscopy; compared with CT and EUS, which was in fair agreement. The strength of agreement between preoperative M stage and final M stage was in almost perfect agreement (Kw = 0.990; 95% CI: 0.977-1.000; P laparoscopy; compared with CT, which was in slight agreement. Multivariate analysis revealed that tumor size (≥ 40 mm), depth of tumor invasion (T4b), and Borrmann type (III or IV) were significantly correlated with either peritoneal metastasis or positive cytology. The best performance in diagnosing P-positive was obtained when two or three risk factors existed. Staging laparoscopy can improve treatment decision-making for advanced GC and decrease unnecessary exploratory laparotomy.

    Objectives: We compared the indication of laparoscopy for treatment of adnexal masses based on the risk scores and tumor diameters with the indication based on gynecology-oncologists' experience. Methods: This was a prospective study of 174 women who underwent surgery for adnexal tumors (116 laparotomies, 58 laparoscopies). The surgeries begun and completed by laparoscopy, with benign pathologic diagnosis, were considered successful. Laparoscopic surgeries that required conversion to laparotomy, led to a malignant diagnosis, or facilitated cyst rupture were considered failures. Two groups were defined for laparoscopy indication: (1) absence of American College of Obstetrics and Gynecology (ACOG) guideline for referral of high-risk adnexal masses criteria (ACOG negative) associated with 3 different tumor sizes (10, 12, and 14 cm); and (2) Index of Risk of Malignancy (IRM) with cutoffs at 100, 200, and 300, associated with the same 3 tumor sizes. Both groups were compared with the indication based on the surgeon's experience to verify whether the selection based on strict rules would improve the rate of successful laparoscopy. Results: ACOG-negative and tumors ≤10 cm and IRM with a cutoff at 300 points and tumors ≤10cm resulted in the same best performance (78% success = 38/49 laparoscopies). However, compared with the results of the gynecology-oncologists' experience, those were not statistically significant. Discussion: The selection of patients with adnexal mass to laparoscopy by the use of the ACOG guideline or IRM associated with tumor diameter had similar performance as the experience of gynecology-oncologists. Both methods are reproducible and easy to apply to all women with adnexal masses and could be used by general gynecologists to select women for laparoscopic surgery; however, referral to a gynecology-oncologist is advisable when there is any doubt.

    The purpose of this study was to determine the feasibility of virtual endoscopy, named as ''virtual CT laparoscopy'', in the hepatobiliary system prior to laparoscopic cholecystectomy. We applied this technique to 28 patients suspected of having biliary disease. These images were compared and analyzed qualitatively based on visualization of the structures critical to operative cholangiography and surgical findings. Twenty-four patients, who underwent laparoscopic cholecystectomy, were evaluated as follows: the common bile duct and the hepatic duct were adequately visualized in 23 (96%) of the 24 patients, the cystic duct in 21 (88%), the gallbladder opacification in 20 (83%), the liver inferior surface in 20 (83%). Four patients had anatomic variations detected virtual CT laparoscopy and were proven by operative cholangiography and surgical findings. We emphasize that our new technique may contribute to the laparoscopy during surgery as the aid of understanding of anatomical structures in these organs. (author)

  5. Laparotomy and laparoscopy diversely affect macrophage-associated antimicrobial activity in a murine model

    2013-01-01

    Background Surgical intervention-related trauma contributes largely to the development of postoperative immunosuppression, with reduced resistance to secondary bacterial infection. This study compared the impact of laparotomy versus laparoscopy on macrophage-associated bactericidal ability and examined whether laparotomy renders the host more susceptible to microbial infection. Results BALB/c mice were randomized into control, laparotomy, and laparoscopy groups. Laparotomy, but not laparoscopy, significantly downregulated CR3 expression on macrophages, diminished macrophage-induced uptake and phagocytosis of E. coli and S. aureus, and impaired macrophage-mediated intracellular bacterial killing. Consistent with this, mice that underwent laparotomy displayed substantially higher bacterial counts in the blood and visceral organs as well as a significantly enhanced mortality rate following bacterial infection, whereas mice subjected to laparoscopy did not show any defects in their bacterial clearance. Conclusion Laparotomy has an adverse effect on host innate immunity against microbial infection by impairing macrophage-mediated phagocytosis and killing of the invaded bacteria. By contrast, laparoscopy appears to preserve macrophage-associated bactericidal ability, thus alleviating the development of postoperative immunosuppression. PMID:23786397

    Background The use of fluorescent proteins to label tumors is revolutionizing cancer research, enabling imaging of both primary and metastatic lesions, which is important for diagnosis, staging, and therapy. This report describes the use of fluorescence laparoscopy to image green fluorescent protein (GFP)-expressing tumors in an orthotopic mouse model of human pancreatic cancer. Methods The orthotopic mouse model of human pancreatic cancer was established by injecting GFP-expressing MiaPaCa-2 human pancreatic cancer cells into the pancreas of 6-week-old female athymic mice. On postoperative day 14, diagnostic laparoscopy using both white and fluorescent light was performed. A standard laparoscopic system was modified by placing a 480-nm short-pass excitation filter between the light cable and the laparoscope in addition to using a 2-mm-thick emission filter. A camera was used that allowed variable exposure time and gain setting. For mouse laparoscopy, a 3-mm 0° laparoscope was used. The mouse’s abdomen was gently insufflated to 2 mm Hg via a 22-gauge angiocatheter. After laparoscopy, the animals were sacrificed, and the tumors were collected and processed for histologic review. The experiments were performed in triplicate. Results Fluorescence laparoscopy enabled rapid imaging of the brightly fluorescent tumor in the pancreatic body. Use of the proper filters enabled simultaneous visualization of the tumor and the surrounding structures with minimal autofluorescence. Fluorescence laparoscopy thus allowed exact localization of the tumor, eliminating the need to switch back and forth between white and fluorescence lighting, under which the background usually is so darkened that it is difficult to maintain spatial orientation. Conclusion The use of fluorescence laparoscopy permits the facile, real-time imaging and localization of tumors labeled with fluorescent proteins. The results described in this report should have important clinical potential. PMID:20533064

    Meckel diverticulum can present with a variety of complications but is often found incidentally during other surgical procedures. The role of laparoscopy in the management of Meckel diverticulum is established. We reviewed our experience with complicated cases of Meckel diverticulum in children managed with laparoscopy. A 15-year retrospective chart review revealed 14 cases of complicated Meckel diverticulum managed with laparoscopy. Incidentally found Meckel diverticulum and cases done by laparotomy were excluded. Ages varied from 2 years to 16 years old. There were 10 males and four females. Eight cases had small bowel obstruction; of those, three had extensive intestinal gangrene. Four cases had significant rectal bleeding, three had acute diverticulitis, and two had intussusception caused by the diverticulum. Eleven cases were treated with laparoscopic Meckel diverticulectomy and three with laparoscopic-assisted bowel resection because of extensive gangrene of the intestine. Two of the three cases with significant intestinal gangrene returned several weeks later with small bowel obstruction secondary to adhesions. They were successfully managed with laparoscopic lysis of adhesions. There were no other complications. Laparoscopy is safe and effective in the management of complicated Meckel diverticulum in children. Most cases can be managed with simple diverticulectomy. Laparoscopy is useful when the diagnosis is uncertain. When extensive gangrene is present, laparoscopy can help to mobilize the intestine and evaluate the degree of damage, irrigate and cleanse the peritoneal cavity, and minimize the incision necessary to accomplish the bowel resection.

    AIM: To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

    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 general 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

    To investigate the recurrence rate and disease-free interval between laparoscopy versus laparotomy for the conservative surgery of endometrioma. A retrospective cohort study was conducted. The medical records of reproductive women who underwent conservative ovarian cystectomy surgery (laparoscopy or laparotomy) for endometrioma at Thammasat University Hospital were retrieved. The patients were followed through 24 months to evaluate the recurrence of endometrioma. Propensity scoring was used to adjust for confounding by indication and confounding by contraindication. Model for competing time to event was used in analysis. One hundred and twenty-eight and 114 patients were enrolled in laparoscopy and laparotomy groups, respectively. Mean age and body weight in laparotomy group were statistically higher than those in the other group were. Mean height and body mass index were, however not statistically different in either groups. In addition, the stage of disease and bilaterality in both groups were comparable. Diameter ofendometrioma in laparotomy group was significantly larger than that in laparoscopy group (7.0 ± 2.5 vs. 6.2 ± 1.8 cm, respectively; p = 0.004). After adjusting for propensity scoring, the endometrioma recurrence rate was significantly higher in laparoscopy group as compared to laparotomy group (27.3% vs. 14.9%, respectively; p = 0.02). However, the cumulative rate of pregnancy after surgery was not statistically different (4.7% vs. 4.4%, respectively; p = 1.0). The present study has demonstrated that the surgical technique has a strong impact on the recurrence or disease-free interval. Laparoscopy might not eradicate the disease pathology as effectively as open laparotomy in some situations, such as in cases with complexity of disease.

    Cholangiocarcinoma is a rare cancer with a poor prognosis. Radical surgical resection is the only option for curative treatment. Optimal determination of resectability is required so that patients can be stratified into operative or chemotherapeutic treatment cohorts in an accurate and time-efficient manner. Staging laparoscopy is utilized to determine the presence of radiologically occult disease that would preclude further surgical treatment. The aim of this study was to analyse the utility of staging laparoscopy in a contemporary cohort of patients with perihilar cholangiocarcinoma. Patients diagnosed with potentially resectable perihilar cholangiocarcinoma between January 2010 and April 2015 were analysed retrospectively from a prospective database linked to UK Hospital Episode Statistics data. Patients with distal cholangiocarcinoma and gallbladder cancer were excluded from analysis. A total of 431 patients with perihilar cholangiocarcinoma were referred for assessment of potential resection at a supraregional referral centre. Some 116 patients with potentially resectable disease subsequently underwent surgical assessment. The cohort demonstrated an all-cause yield of staging laparoscopy for unresectable disease of 27·2 per cent (31 of 114). The sensitivity for detection of peritoneal disease was 71 per cent (15 of 21; P laparoscopy was 66 per cent (31 of 47) with a positive predictive value of progress to resection of 81 per cent (69 of 85). Neither the Bismuth-Corlette nor the Memorial Sloan Kettering Cancer Center preoperative scoring system was contingent with cause of unresectability at staging laparoscopy (P = 0·462 and P = 0·280 respectively). In the present cohort, staging laparoscopy proved useful in determining the presence of radiologically occult metastatic disease in perihilar cholangiocarcinoma. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Objective We assessed the direct costs of 3 surgical approaches in uterine cancer and the cost impact of incorporating robot-assisted surgery. Methods A cost system that allocates the actual cost of resources used to treat each patient, as opposed to borrowing cost data from a billing system, was used to determine direct costs for patients who underwent surgery for uterine cancer from 2009–2010. These costs included all aspects of surgical care up to 6 months after discharge. Total amortized direct costs (AC) included the capital cost of 3 dual console DaVinci Si platforms with 5 years of service contracts. Non-amortized costs (NAC) were also calculated (excluded capital costs). Modeling was performed to estimate the mean cost of surgical care for patients presenting with endometrial cancer from 2007–2010 Results Of 436 cases (132 laparoscopic, 262 robotic, 42 laparotomy), total mean AC/case was $20,489 (laparoscopy), $23,646 (robot), and $24,642 (laparotomy) (P<0.05 [robot vs laparoscopy]; P=0.6 [robot vs laparotomy]). Total NAC/case was $20,289, $20,467, and $24,433, respectively (P=0.9 [robot vs laparoscopy]; P=0.03 [robot vs laparotomy]). The planned surgical approach in 2007 was laparoscopy-68%, robot-8%, and laparotomy-24% compared to 26%, 64%, and 9%, respectively, in 2010 (P<0.001). The modeled mean AC/case was $21,738 in 2007 and $22,678 in 2010 (+$940). NAC was $21,298 in 2007 and $20,573 in 2010 (−$725). Conclusion Laparoscopy is least expensive when including capital acquisition costs. Laparoscopy and robotic surgery are comparable if upfront costs are excluded. There is cost neutralization with the robot when it helps decrease laparotomy rates. PMID:24785856

    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.

    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.).

    To compare postoperative pain after conventional laparoscopic and robotically assisted laparoscopic surgery in gynecology. This is a prospective nonrandomized analysis of patients undergoing conventional laparoscopy or robotically assisted laparoscopy in a university-affiliated hospital between March 2011 and March 2012. Postoperative pain was measured using the Numeric Rating Scale and the narcotic use converted to morphine sulfate equivalents. The primary outcome was the Numeric Rating Scale pain score obtained on the first postoperative day. One hundred ten patients were enrolled; 91 were included in the statistical analysis. Both groups were similar with regard to race, history of abdominopelvic surgeries, psychiatric history, and substance abuse. Patients undergoing robotically assisted laparoscopy were 6 years older and had a body mass index 6 points higher. Median length of hospital stay for conventional laparoscopy and robotically assisted laparoscopy was 2 days and 3 days, respectively (P<.001); median to being off narcotics was 4 days and 4.5 days, respectively (P=.336); and median return to normal activities was 13 days and 21 days, respectively (P=.021). There were no significant differences in mean Numeric Rating Scale pain scores over time (P=.499) or mean narcotic requirements (P=.393) between groups. Robotically assisted laparoscopy is equivalent to conventional laparoscopy in terms of subjective and objective measures of postoperative pain.

    With reference to your correspondence (September 27, p. 764, and December 27, p. 760) regarding laparoscopy explosion hazards with nitrous oxide, in our experience this is not substantiated. In the last 18 months we have done some 123 laparoscopies in the Medical City Hospital, Baghdad. We have done 16 sterilizations by tubal diathermy and not fewer than 12 cases where biopsies were taken from ovaries in case of tuberculosis or for other reasons, where diathermy was used. In all our laparoscopy procedures we always used nitrous oxide gas because carbon dioxide cylinders are difficult to otain. We did not have any incident of explosion, and most of our patients stayed in hospital not more than 24 hours postoperatively, during which time no complications were reported. None of these cases was readmitted for any complications. It seems to us that the hazard of explosion with nitrous oxide is more theoretical than real.

    The present study aims to evaluate the role of laparoscopy in frail patients undergoing colorectal surgery for colorectal cancer. A review of the 2011 to 2014 American College of Surgeons National Surgical Quality Improvement Program database was performed to identify frail patients (using a frailty index), who underwent resection for colorectal cancer. Univariable and multivariable analyses were performed to evaluate 30-day mortality and Clavien-Dindo grade IV (CD-IV) complications. A total of 52,087 patients with colorectal cancer were identified, of which frailty accounted for 2.63 per cent (index score ≥5). Patients above the age 85 were considered frail 6.8 per cent of the time and accounted for 24.5 per cent of patients with frailty. Laparoscopic surgery was performed in 32.9 and 53.1 per cent of patients with and without frailty (P < 0.001). Patients with frailty were less likely to die within 30 days of surgery if younger (P = 0.004), performed electively (P < 0.001), or laparoscopically (P < 0.001). On multivariate analysis, laparoscopy and elective surgery were associated with better perioperative survival; whereas, older age, male sex, and tobacco use were associated with 30-day mortality. Laparoscopy and lower body mass index were associated with fewer Clavien-Dindo grade IV complications. Although laparoscopy is performed less commonly in the frail, this study indicated better perioperative outcomes for patients undergoing elective surgery who were <85 years old.

    Abstract The aim of this study was to compare the safety and morbidity of laparoscopic versus laparotomic comprehensive staging of apparent early stage ovarian cancer. In this retrospective study, the outcomes of patients with apparent stage I ovarian cancer who underwent laparoscopic or laparotomic comprehensive surgical staging from January 2002 to January 2014 were evaluated. The long-term survival of patients with early ovarian cancer was compared. Forty-two patients were treated by laparoscopy, and 50 were treated by laparotomy. The median operative time was 200 minutes in the laparoscopy group and 240 minutes in the laparotomy group (P >0.05). The median length of hospital stay was 3 days in the laparoscopy group and 7 days in the laparotomy group (P laparoscopy and laparotomy groups. Laparoscopic and laparotomic comprehensive staging of early ovarian cancer were similar in terms of staging adequacy, accuracy and survival rate. Laparoscopic staging was associated with a significantly reduced hospital stay. Prospective randomized trials are required to evaluate the overall oncologic outcomes. PMID:27196468

    In order to support the operation of ITER and the planned experimental programme an extensive set of plasma and first wall measurements will be required. The number and type of required measurements will be similar to those made on the present-day large tokamaks while the specification...... of the measurements—time and spatial resolutions, etc—will in some cases be more stringent. Many of the measurements will be used in the real time control of the plasma driving a requirement for very high reliability in the systems (diagnostics) that provide the measurements. The implementation of diagnostic systems......&D is needed to prepare the systems. In some cases the environmental difficulties are so severe that new diagnostic techniques are required. The starting point in the development of diagnostics for ITER is to define the measurement requirements and develop their justification. It is necessary to include all...

  1. Adhesions and Adhesiolysis: The Role of Laparoscopy

    Kavic, Suzanne M.

    2002-01-01

    Background: Adhesions commonly result from abdominal and pelvic surgical procedures and may result in intestinal obstruction, infertility, chronic pain, or complicate subsequent operations. Laparoscopy produces less peritoneal trauma than does conventional laparotomy and may result in decreased adhesion formation. We present a review of the available data on laparoscopy and adhesion formation, as well as laparoscopic adhesiolysis. We also review current adjuvant techniques that may be used by practicing laparoscopists to prevent adhesion formation. Database: A Medline search using “adhesions,” “adhesiolysis,” and “laparoscopy” as key words was performed for English-language articles. Further references were obtained through cross-referencing the bibliography cited in each work. Discussion: The majority of studies indicate that laparoscopy may reduce postoperative adhesion formation relative to laparotomy. However, laparoscopy by itself does not appear to eliminate adhesions completely. A variety of adjuvant materials are available to surgeons, and the most recent investigation has demonstrated significant potential for intraperitoneal barriers. Newer technologies continue to evolve and should result in clinically relevant reductions in adhesion formation. PMID:12113430

    Full Text Available Assisted reproductive technologies are used to accelerate genetic gain and improve reproductive performances in farm animals, including small ruminants. This technologies include estrous synchronization, artifi cial insemination (AI using fresh, frozen or sexed semen, embryo transfer (ET using in vivo or in vitro produced embryos, and more advanced - cloning and production of transgenic animals. Diagnostic procedures, such as ultrasonography and laparoscopy, have been used as additional tools for monitoring the ovarian response to superovulatory treatment in donor animals as well as for AI and collection and transfer of embryos. The use of laparoscopy for assisted reproduction techniques in Macedonia commenced in the early 90’s, with the acquisition of a set of ,,Karl Storz” equipment. After the adoption of the required routine, our group has completed several scientifi c projects where laparoscopy was used for intrauterine inseminations as well as for recovery and transfer of embryos in both sheep andgoats. In the following period our group endeavored into introduction of laparoscopic insemination in the routine farm practice. Ovine intrauterine/intracornual insemination by frozen-thawed semen resulted with pregnancy rates of 45% and 60%, when AI was performed out of season and during the breeding season, respectively. In goats, this percentage occasionally peaked at 85%. The aim of this article is to review the status of implementation of laparoscopy in Assisted Reproduction Technologies (ART of small ruminants and to present our experience in this field.

    Full Text Available Background. The aim of this retrospective study was to find the incidence and type of adnexal masses in pregnancy, reliability of preoperative ultrasound examination and the effect of the surgical approach used, duration of pregnancy at the time of surgery, and the effect of emergency or planned surgery on the outcome of pregnancy. The obtained results and the data from literature were to provide the basis of the guidelines for the management of pregnant women with adnexal masses.Methods. In the study we enrolled 42 women, who underwent a surgery in pregnancy for adnexal masses. All surgeries were performed at the Department of Obstetrics and Gynecology in the period 1 January 1993–31 August 2000. The course of pregnancy was followed by 28 February 2001. The data were obtained from the records kept at the Department and from the questionnaire sent to the women. Statistical analysis was done using Chi-square test. Statistical significance was set at P ≤ 0.05.Results. We found the incidence of adnexal masses in pregnancy, requiring surgical treatment, to be 1/1034 deliveries. There were 6 (14.3% borderline malignant and malignant ovarian tumours, the incidence being 1/7239 deliveries. Preoperative ultrasound examination was not reliable enough to differentiate neither between benign and malignant adnexal masses, nor between adnexal masses and leiomyomas. Forty-two surgeries were made, 21 by laparoscopy and 21 by laparotomy. The size of removed tumours ranged between 4 and 30 cm (mean 9.4 cm, the most frequent type was mature cystic teratoma (n = 12. There were no differences in the outcome of pregnancy between the laparoscopy and laparotomy approach, between emergency and planned surgery, and between laparotomy performed by the 23rd and after the 23rd gestational week. Hemorrhagic shock due to heterotopic pregnancy lead to 1 spontaneous abortion. There were 2 preterm deliveries in the 37th week, 2 babies had intrauterine growth retardation

    Metastatic disease to the liver is one of the major factors determining the outcome of colonic resection with curative interventions in human patients. Therefore, animal models for studies of liver metastasis have been developed. Humane endpoints are needed for the evaluation of the animal...... impression of the metastases was obtained. We suggest, as a new humane endpoint, that one animal should only have 1-2 separately growing metastases, each of a maximum size of 10 mm(2). In future, the method has to be developed further to measure the size of the metastases in a more quantitatively precise...... manner. Although the animal has to be anaesthetized each time, laparoscopy is considered a minor surgical procedure as only two small puncture wounds are made through the abdominal wall. Because laparoscopy offers a direct view of the hidden tumours and their sizes, as well as of possible complications...

    Laparoscopy is considered the method of choice in the operative treatment of type I endometrial carcinoma (EC). However, there is a paucity of data regarding the safety of endoscopy for type II EC because these malignancies have several biological similarities with ovarian cancer. This study aimed to evaluate the feasibility, operative outcomes, and oncologic safety of laparoscopic surgery in patients with type II EC. A retrospective study with histologically confirmed serous or clear-cell EC without peritoneal carcinomatosis treated by laparoscopy (G1) or laparotomy (G2) was conducted. Procedures included hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymphadenectomy. From 2009 to 2015, 89 patients were included; 53 women underwent laparoscopy and 36 underwent laparotomy. No relevant epidemiological or oncologic difference between groups was observed. The mean number of removed pelvic nodes was 16 [±10] and 12 [±13] in group 1 (G1) and group 2 (G2), respectively (P = 0.127). The mean number of dissected para-aortic nodes was significantly greater in the laparoscopic group (11 [±9] vs 6 [±9], P = 0.006). Para-aortic metastasis was significantly more often observed in the endoscopy group (26% vs 13%, P = 0.04). Adjuvant therapies were given to 86% of the patients in the study and 75% in the control group (P = 0.157). No excessive blood loss, casualty related to surgery, intraoperative complication, or conversion to laparotomy occurred in G1. Ten (18%) women from G1 and 36% (13/36) in G2 developed relevant postoperative complications (P = 0.03). The median duration of follow-up was 38 months for the laparoscopy and 47 months for the open surgery (P = 0.12). The 5-year overall and disease-free survival were similar, 86% versus 78% and 58% versus 51% for G1 and G2, respectively (P = 0.312). Laparoscopy is oncologically at least not inferior to laparotomy for the surgical treatment of type II EC. Endoscopic techniques are

    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.

    The staging laparoscopy has been used in the management of gastrointestinal cancers. The aim of this study was to evaluate the role of staging laparoscopy, in comparison with computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FDG-PET) imaging in staging patients with gastro-oesophageal junction (GOJ) and gastric cancers. The data were collected for patients between 1996 and 2013 undergoing investigation and treatment for GOJ and gastric cancers at a single institute. The pre-operative data (staging data), intraoperative details, post-operative course and follow-up were analysed for individual cases. Staging laparoscopy altered management plan in 64 (17 %) of 387 patients with negative staging CT and FDG-PET scan. Twenty-seven (7 %) patients with GOJ cancer (types I, II and III) were identified with pathological intraperitoneal nodes, 15 (4 %) gastric cancer with metastatic intraperitoneal deposits and liver metastases and 3 % gastric cancers with positive ascitic fluid for cancer cells. Ten (3 %) of patients were downstaged and were offered curative resection. Patients with metastatic disease were referred for palliative chemotherapy. The overall sensitivity of staging laparoscopy in diagnosing intraabdominal pathology was 86 % in comparison with CT (81 %) and FDG-PET (78 %). The diagnostic laparoscopy is useful for detecting and confirming nodal involvement and distant metastatic disease not evident on the staging CT scan and FDG-PET. This could potentially alter treatment and prognosis in patients with upper gastrointestinal cancer. The diagnostic laparoscopy should be performed as part of investigation and treatment planning for patients suffering from GOJ and gastric cancers. This can help to avoid surgery in patients with advanced disease.

    Introduction and aim: Ovarian carcinoma (OC) is a common cancer in the Western Countries, and an important cause of death in patients suffering with gynaecologic malignancies. The majority of patients present with advanced disease at the time of diagnosis. Treatment with debulking surgery followed by chemotherapy is the standard approach while chemotherapy is contemplated when surgery is not possible. A correct pre-operative staging is important to ensure a most appropriate management. Laparoscopy (LPS) is the standard diagnostic tool for the assessment of intraperitoneal infiltration but is invasive and requires general anaesthesia. FDG-PET/CT is increasingly used for staging different types of cancer, and the aim of this study is to assess the value of FDG-PET/CT in staging advanced OC and its sensitivity to detect lesions in different quadrants of the abdominal-pelvic area compared to laparoscopy. Materials and methods: From September 2004 till April 2008, 40 patients with high suspicion of OC were referred to our hospital for diagnostic LPS to explore the possibility of optimal debulking surgery. Those who were not suitable for surgery were referred for chemotherapy. Before chemotherapy, the patients underwent an FDG-PET/CT scan. The findings in 9 quadrants of abdominal-pelvic area (total 360 quadrants) for PET/CT and LPS were recorded and compared. Results: In 14/360 areas (3.8%), surgical evaluation was not possible because of presence of adhesions, thus the number of areas explored by laparoscopy was 346. Tumour was found in 308 quadrants (38 quadrants free of disease). PET/CT was positive in all 40 patients with true negative results in 26/346 quadrants (7.5%), and true positives results in 243/346 quadrants (70.2%). False positive and negative PET/CT results were found in 12/346 and 65/346 quadrants, respectively. False positive PET/CT findings were evenly present in all quadrants. False negative PET/CT findings were present in 31/109 (28.4%) upper

    Gynecologic applications of optical coherence tomography (OCT) are usually performed in combination with routine diagnostic procedures: laparoscopy and colposcopy. In combination with laparoscopy OCT is employed for inspection of fallopian tubes in cases of unrecognized infertility while in colposcopy it is used to identify cervix pathologies including cancer. In this paper we discuss methods for increasing diagnostic efficacy of OCT application in these procedures. For OCT-laparoscopy we demonstrate independent criteria for pathology recognition which allow to increase accuracy of diagnostics. For OCT-colposcopy we report on application of device for controlled compression allowing to sense the elasticity of the inspected cervix area and distinguish between neoplasia and inflammatory processes.

    Little is known about postgastrectomy syndrome and quality of life (QOL after laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). The aim of this study was to assess postgastrectomy syndrome and QOL after LAPPG as compared with laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction (LADGBI). Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaires were sent by mail to 167 patients. To balance the characteristics of the groups, propensity score matching was performed. Of the 167 patients sent questionnaires, 112 (67%) responded, including 47 who underwent LAPPG and 65 who underwent LADGBI. After propensity score matching, the LAPPG group scored significantly better on the diarrhea and dumping subscales. Multiple regression analysis showed that female sex and LADGBI were independent factors predicting dumping. Evaluation of outcome measures for singular symptom showed that the LAPPG group scored significantly worse on the acid regurgitation subscale, but significantly better on the lower abdominal pain and early dumping abdominal subscales. LAPPG is superior to LADGBI for ameliorating postgastrectomy syndrome and maintaining QOL. LAPPG is recommended for patients with cT1N0 middle third gastric cancer. Copyright © 2016 Elsevier Inc.

    To assess the efficacy of analgesia provided by continuous ropivacaine wound infiltration after gynecologic laparoscopy. Sixty patients who underwent gynecologic laparoscopy at Ajou University School of Medicine, Suwon, Republic of Korea, between March and May 2012 were randomized to receive either intravenous fentanyl and ketorolac infusion on demand by patient-controlled analgesia (IV PCA group, n=31) or continuous wound infiltration of local ropivacaine (CWI group, n=29). Postoperative pain and postoperative nausea and vomiting (PONV) were assessed via a visual analog scale. The number of patients who requested rescue analgesia was recorded. There was no significant difference in postoperative pain between the 2 groups, but more patients requested rescue analgesia in the CWI group than in the IV PCA group in 24 hours (18 versus 9 patients, respectively; P=0.010). The PONV scores at 12 and 24 hours were, respectively, 0.28 and 0.27 in the CWI group, and 0.71 and 0.73 in the IV PCA group (P=0.004). Nine patients requested cessation of IV PCA because of severe nausea or vomiting. Continuous ropivacaine wound infiltration was found to be as effective as patient-controlled analgesia for postoperative pain relief after gynecologic laparoscopy. This technique provides good analgesia with less opioid analgesic requirement and few adverse effects. Copyright © 2013 International Federation of Gynecology and Obstetrics.

    To evaluate the effects of CO2 pneumoperitoneum during gynecologic laparoscopy on patients' postoperative cognitive function. This prospective clinical study included 225 adult female patients with American Society of Anesthesiologists physical status I or II. Patients underwent conventional open surgery (group I, n = 115) or gynecologic laparoscopy using abdominal insufflation with CO2 to an intra-abdominal pressure of 15 mm Hg (group II, n = 110). Serum S100β and neuron-specific enolase (NSE) concentrations were measured, both immediately before surgery and before the patient awoke after surgery. The Mini-Mental State Examination (MMSE) was administered 1 day before surgery as well as 1, 6, 12, 24 and 72 h after surgery and before discharge. MMSE scores were significantly lower relative to baseline at 1, 6 and 12 h post surgery, but returned to baseline by 48 h (group I) or 72 h (group II) post surgery. One hour after surgery, S100β serum levels were higher in group II than in group I (p gynecologic laparoscopy. © 2015 S. Karger AG, Basel.

    The authors discuss 47 cases in which the hysterosalpingography (HSG) examination showed secondary tubar unpatency, then verified by laparoscopy. In the opinion of the authors supported by the results the HSG examination may be considered only as a preliminary element of tubar patency examination. In case of planned microsurgery the only qualifying or disqualifying examination is the laparoscopy with introduction of color contrast. (author)

    Laparoscopy has become the gold standard for many surgical cases in the developed world. It however, remains a rarity in developing countries for several reasons, a major one being cost. This study aimed to determine the knowledge and attitude of patients attending Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana toward laparoscopic surgery and their willingness to pay for it. A cross-sectional survey was conducted among patients attending specialist clinics at KATH. 1070 patients participated. Mean age was 40±15 years. 54% were city-dwellers. 14% had salary-paying jobs. None had undergone prior laparoscopic surgery. 3% had knowledge of laparoscopy. 95% preferred laparoscopy to open surgery mainly because of faster recovery and less post-op pain. Age >45 years (AOR = 0.53, p = 0.03) and higher education (AOR = 2.00, p = 0.04) were significant predictors of patient choice. Among those preferring laparoscopy, 78% were willing to pay more than the baseline cost of open surgery for laparoscopy. A history of previous abdominal surgery (AOR = 0.67, p = 0.02), having a salaried job compared with being unemployed (AOR = 2.36, p laparoscopy. Knowledge about laparoscopy and its benefits are severely lacking among patients at KATH. Once educated about its benefits, most people prefer laparoscopy even if they needed to pay more for it even in resource-limited countries like Ghana.

    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

    Background To identify indications for staging laparoscopy (SL) in patients with resectable pancreatic cancer, and suggest a pre-operative algorithm for staging these patients. Methods Relevant articles were reviewed from the published literature using the Medline database. The search was performed using the keywords ‘pancreatic cancer’, ‘resectability’, ‘staging’, ‘laparoscopy’, and ‘Whipple's procedure’. Results Twenty four studies were identified which fulfilled the inclusion criteria. Of the published data, the most reliable surrogate markers for selecting patients for SL to predict unresectability in patients with CT defined resectable pancreatic cancer were CA 19.9 and tumour size. Although there are studies suggesting a role for tumour location, CEA levels, and clinical findings such as weight loss and jaundice, there is currently not enough evidence for these variables to predict resectability. Based on the current data, patients with a CT suggestive of resectable disease and (1) CA 19.9 ≥150 U/mL; or (2) tumour size >3 cm should be considered for SL. Conclusion The role of laparoscopy in the staging of pancreatic cancer patients remains controversial. Potential predictors of unresectability to select patients for SL include CA 19.9 levels and tumour size. PMID:26776846

    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.

    To compare the analgesic efficacy of caudal block with diclofenac suppository and local anesthetic infiltration in children undergoing laparoscopy. We studied 50 children undergoing laparoscopy for diagnostic and therapeutic purposes. Their ages ranged from 3 to 13 years, and all belonged to American Society of Anesthesiologists (ASA) class I or II. Anesthesia was carried out using the standard procedure. Patients were randomly assigned to one of two groups. Group 1 received caudal block with bupivacaine 1 mL/kg after anesthetic induction. Group 2 received diclofenac suppository 3 mg/kg postinduction and local anesthetic infiltration at the port sites at the end of the procedure. Pain was assessed using the Hannallah objective pain scale at 15, 30, 60, 120, and 360 minutes postextubation. The pain scores were comparable in both groups at all times. Twelve percent of caudal block patients and 20% of diclofenac patients needed rescue analgesic, a statistically insignificant difference. In 2 patients, caudal block was technically difficult and they were excluded from the study. The incidence of side effects was low in our study. We find the analgesic efficacy of diclofenac suppository combined with local anesthetic infiltration at port sites comparable to caudal block. Given the necessarily invasive nature of caudal block, we suggest the combined use of diclofenac suppository with local anesthetic infiltration at port sites as a useful and more economical alternative for analgesia following pediatric laparoscopy.

    We report a case of port-site metastasis after laparoscopic surgery for early stage uterine carcinosarcoma (UCS) and review the related literature. A 53-year-old woman with suspected uterine malignance underwent a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy, infra-colic omentectomy, and pelvic lymphadenectomy resulting pathologically in a stage IA UCS. Twelve months later she developed a palpable abdominal-wall mass at the trocar site without other synchronous metastases. A mass resection was performed and it was pathologically diagnosed with port-site metastasis of UCS. When performing surgery for UCS, specimens should be carefully removed in case small pieces of the occult disseminated metastatic tissues are trapped between the outer surface of the trocar sleeve and the abdominal wall incisional canal. Despite the low incidence, a laparotomy might be considered rather than laparoscopy to prevent port-site metastasis and more gynecological oncology clinical practices might be relevant to the management of port-site metastasis. © 2017 The Korean Academy of Medical Sciences.

    Full Text Available Introduction. Congenital pelviureteric junction obstruction (PUJO is one of the most common causes of hydronephrosis. Historically, open dismembered pyeloplasty has been considered the gold standard intervention for correcting PUJO. The aim of this study was to compare the surgical and functional outcomes of three different approaches, namely, open, conventional laparoscopy, and robotic pyeloplasty. Material and Methods. 60 patients underwent minimally invasive pyeloplasty (30 conventional laparoscopies and 30 robotics for congenital PUJO at a tertiary health center in India. Demographic, perioperative, and postoperative data were prospectively collected and analyzed. The data of these patients were retrospectively compared with another cohort of 30 patients who had undergone open pyeloplasty. Results. There was significant difference in operative time, time to drain removal, hospital stay, pain score, and complications rate between open and minimally invasive pyeloplasty (P<0.05. SFI was considerably lesser in robotic as compared to conventional laparoscopy. The success rate in OP, CLP, and RP was 93.33, 96.67, and 96.67%. Conclusion. Robotic pyeloplasty is safe, effective, and feasible. It is associated with significantly lesser operative time, lesser blood loss, less pain, shorter hospital stay, and fewer complications. It is also associated with considerably lesser surgeon fatigue as compared to conventional laparoscopy pyeloplasty.

    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 environmental impact of their decisions to facilitate adoption of sustainable practices.

    To compare robot-assisted laparoscopy (RL) and conventional laparoscopy (CL) in surgery for bladder endometriosis. A retrospective study was conducted between January 2007 and December 2013, including patients with bladder endometriosis receiving at least a partial cystectomy by RL or CL. The primary endpoint was the presence of a radiological recurrence at bladder level. We included 15 patients in the RL group and 22 in the CL group. The median age was 29 years±7 years. The symptoms were similar in the 2 groups. Pre-surgical mapping of the lesions was carried out with MRI. Sixty percent of patients in the RL group vs 91% in the CL group had other associated endometriosis lesions, P=0.04. The median size of the bladder lesion was 30±8mm in the RL group vs 23±7mm in the CL group, P=0.03. The median operative time was 210 vs 225min, P=0.8. We did not find any significant difference in intraoperative and early and late postoperative complications between the 2 groups. The median length of stay was 5 days vs 6 days. The proportion of relapse was 20 vs 23%, P>0.05. Clinical improvement was similar between the groups, i.e. 93 vs 86%, P=0.6 and the pregnancy rate was 93 vs 86%, P=0.6. Robot-assisted laparoscopy in the surgical treatment of bladder endometriosis as compared to traditional laparoscopy does not seem to have an adverse effect neither on the risk of recurrence nor on the occurrence of intra- and postoperative complications.

    The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers, for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a

    The use of minimally invasive surgery has become widely accepted in many gastrointestinal fields, even in patients with malignancy. However, performing laparoscopic resection for the treatment of hilar cholangiocarcinoma is still not universally accepted as an alternative approach to open surgery, and only a limited number of such procedures have been reported due to the difficulty of performing oncologic resection and the lack of consensus regarding the adequacy of this approach. Laparoscopy was initially limited to staging, biopsy and palliation. Recent technological developments and improvements in endoscopic procedures have greatly expanded the applications of laparoscopic liver resection and lymphadenectomy, and some reports have described the use of laparoscopic or robot-assisted laparoscopic resection for hilar cholangiocarcinoma as being feasible and safe in highly selected cases, with the ability to obtain an adequate surgical margin. However, the benefits of major laparoscopic surgery have yet to be conclusively proven, and carefully selecting patients is essential for successfully performing this procedure. PMID:25386064

    Pneumoperitoneum is the beginning procedure of laparoscopy to enlarge the abdominal cavity in order to allow the surgical instruments to insert for surgical purpose. However, the insertion of Veress needle is a blind fashion that could cause blood vessels or visceral injury without attention and results in undetectable internal bleeding. Seriously it may cause a life-threatened complication. We have developed a method that can monitor the tissue reflective spectrum, which can be used for tissue discrimination, in real time during the puncture of the Veress needle. The system includes a modified Veress needle which containes an optical bundle, a light spectrum analyzing and control unit. Therefore, the tissue reflective spectrum can be vivid observed and analyzed through the fiber optical technology during the procedure of the Veress needle insertion. In this study, we have measured the reflective spectra of various porcine abdominal tissues. The features of their spectra were analyzed and characterized to build up the data base and create an algorithm for tissue discrimination in laparoscopy. The results showed that the correlation coefficient (r) of the reflective spectrum can be 0.79-0.95 for the wavelength range of 350-1000 nm and 0.85-0.98 for the wavelength range of 350-650 nm in the same tissue of various samples which were obtained from different days. An alternative way for tissue discrimination is achieved through a decision making tree according to the characteristics of tissue spectrum. For single blind test the success rate is nearly 100%. It seems that both the algorithms mentioned above for tissue discrimination are all very promising. Therefore, these algorithms will be applied to in vivo study in animal in the near future.

    The benefits of laparoscopic versus open surgery for patients with both benign and malignant colorectal disease have been well established. Re-laparoscopy in patients who develop complications following laparoscopic colorectal surgery has recently been reported by some groups and the aim of this systematic review was to summarise this literature. A literature search of PubMed, Medline and EMBASE identified a total of 11 studies that reported laparoscopic re-intervention for complications in 187 patients following laparoscopic colorectal surgery. The majority of these patients required re-intervention in the immediate postoperative period (i.e. less than seven days). Anastomotic leakage was the commonest complication requiring re-laparoscopy reported (n = 139). Other complications included postoperative hernia (n = 12), bleeding (n = 9), adhesions (n = 7), small bowel obstruction (n = 4), colonic ischaemia (n = 4), bowel and ureteric injury (n = 3 respectively) and colocutaneous fistula (n = 1). Ninety-seven percent of patients (n = 182) who underwent re-laparoscopy had their complications successfully managed by re-laparoscopy, maintaining the benefits of the laparoscopic approach and avoiding a laparotomy. We conclude that re-laparoscopy for managing complications following laparoscopic colorectal surgery appears to be safe and effective in highly selected patients.

Thirty-two patients underwent TIPAL via robotic-assisted laparoscopy, and 30 via conventional laparoscopy. Comparison analyses of perioperative outcomes and estimated costs were performed. There were no differences between robotic-assisted and laparoscopy insofar as age, body mass index, presurgical morbidity, operating time (92.5 minutes for robotics vs 96.6 minutes for laparoscopy), number of aortic nodes (12 vs. 12), hospitalization stay (2 vs. 2 days), or rate of complications (12.5% vs. 13.3%). Blood loss tended to be lower in the robotic group (75.0 vs. 92.5 mL; p = .08). Surgical cost was higher in the robotic group ($3.42 vs. $2.55; p laparoscopy provide similar perioperative outcomes. However, the robotic-assisted approach is associated with higher surgical cost. Copyright © 2014 AAGL. Published by Elsevier Inc. All rights reserved.

    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

    This study aimed to systematically review and compare the perioperative outcomes of laparoscopy with laparotomy for abdominal trauma patients. We conducted a systematic review and meta-analysis comparing the perioperative outcomes of laparoscopy with laparotomy for abdominal trauma patients. Clinical endpoints included length of hospital stay, operation time, amount of intraoperative blood loss, time to postoperative exhaust, time to regular diet, time to out of bed, duration of postoperative pain, postoperative complications, perioperative mortality rate, length of intensive care unit (ICU) stay, missed injuries, conversions to laparotomy, and cure rate. Sixty-four studies including 9058 patients with abdominal trauma were included. In these studies, laparoscopy was used as a screening, diagnostic, or therapeutic tool. Meta-analysis showed significant reductions in the incidence of postoperative complications (relative risk [RR] [95 % confidence interval (CI)] 0.37 [0.29-0.46]), perioperative mortality rate (RR 0.64; 95 % CI 0.52-0.80), operation time (mean difference [MD] [95 % CI] -19.93 min [-34.43 to 5.43]), length of hospital stay (MD -5.15 days; 95 % CI -6.80 to 3.50), amount of intraoperative blood loss (MD -141.33 ml; 95 % CI -260.99 to 21.67), time to postoperative exhaust (MD -5.32 h; 95 % CI -8.60 to 2.05), time to regular diet (MD -3.46 h; 95 % CI -6.31 to 0.61), time to out of bed (MD -23.51 h; 95 % CI -24.85 to 22.16), duration of postoperative pain (MD -21.34 h; 95 % CI -22.65 to 20.03), length of ICU stay (MD -1.89 days; 95 % CI -4.05 to 0.27) in patients with abdominal trauma treated with laparoscopy compared with laparotomy. The pooled incidence of postoperative complications, missed injuries, conversions, and perioperative mortality rate of laparoscopy among the case reports were 0.04 (95 % CI 0.03-0.06), 0.01 (95 % CI 0.01-0.02), 0.24 (95 % CI 0.20-0.28), 0.01(95 % CI 0.01-0.02), respectively. Cure rate of laparoscopy ranged from 46 to 95 % and

    Retroperitoneoscopic nephrectomy is less invasive than open nephrectomy, and is an alternative surgical procedure for renal tumors and upper urothelial tumors. We evaluated the efficacy of virtual computerized tomography laparoscopy (VCTL) as a navigator for retroperitoneoscopic nephrectomy to ascertain the correct anatomy of the renal hilum pre-operatively under the retroperitoneoscopic view. Seventy-three kidneys with localized renal tumors (n=44), upper urothelial tumors (n=23), or benign renal disease (n=6) underwent multidetector-row CT. VCTL was carried out by the volume-rendered technique. The findings were compared with those of real retroperitoneoscopy. After the operation, each operator scored 1 to 5 in evaluating the usefulness of virtual retroperitoneoscopy (score 5 indicated very useful). The percentages of renal arteries depicted by VCTL compared with those noted during real surgery were 93% for kidneys with renal tumors, 100% for upper urothelial tumors and 83% for benign renal disease. Two renal arteries of 2 kidneys were not detected by virtual imaging. These were about 1 mm in diameter and directly branched from the aorta, however retroperitoneoscopic nephrectomy was performed uneventfully. VCTL depicted all the renal veins. The anatomy of the renal hilum seen on VCTL and real retroperitoneoscopy was identical, without the minor angle deviation caused by drawing the kidney during the operation. The average score for the usefulness of VCTL was 4.1, ranging from 3 to 5. The accurate surgical anatomy of the renal hilum could be predicted in almost all patients pre-operatively. VCTL is an excellent navigator for retroperitoneoscopic nephrectomy. (author)

    Laparoscopic pyeloplasty has emerged as the gold standard for repair of ureteropelvic junction obstruction. Microlaparoscopic (MLP, MLP, using a 5-mm camera in a hidden umbilical incision, and 1.9 or 3 mm working instruments and compared with patients undergoing conventional laparoscopic pyeloplasty (CLP). The data for MLP and CLP were compared using the Student t test, Pearson chi-square test, and Fisher exact test, where appropriate. Between January 2009 and May 2013, there were 19 MLP and 27 CLP procedures performed. The MLP group mean age was younger than the CLP group (34 vs 50 years; P=0.0003). Body mass index, previous treatment rates, operative time, length of stay, ureteral stent duration, and complication rates were not statistically different between the MLP and CLP groups. Strict success rates (indicated by follow-up renal scan T½MLP and CLP groups (89.5% vs 88.9%; P=0.95). No MLP procedures were converted to CLP or open approaches. From technical, perioperative, and outcome perspectives, transperitoneal pyeloplasty with microlaparoscopy is both safe and feasible in our hands compared with conventional laparoscopy, and results in subjectively superior cosmesis. This is the largest MLP series to date and contains, to our knowledge, the only cases described using prototype 1.9 mm instruments.

    By now laparoscopy has become an established access route in gynaecological surgery. It took many years to get to this stage for various obstacles had to be overcome. In the end, it was the low intra- and postoperative complication rates together with the rapid reconvalescence of the patients and their wish to be quickly discharged from hospital which led to an unstoppable diffusion of the method. With the increased use of the procedure and the expertise of the surgeons, it entered the field of gynaecological oncology and met similar reservations. Once again the same convincing advantages helped overcome the resistance. Thus, laparoscopic surgical procedures have secured a place in the treatment of corpus and cervical carcinomas, as their surgical safety has been proved. The aim of future examinations should be the proof of non-inferiority compared to the open techniques because the advantages of the laparoscopic procedure have been sufficiently proved. Regardless of the required proof, the method is rapidly expanding with robot-assisted procedures, while surgeons develop exenterative techniques.

    BACKGROUND Gastric cancer has a high incidence in the elderly in the UK, with a significant number of patients aged 75 years or more. While surgery forms the mainstay of treatment, evidence pertaining to the management of gastric cancer in the Western population in this age group is scarce. METHODS We retrospectively reviewed the outcomes of laparoscopy-assisted total and distal gastrectomies at our centre from 2005 to 2015. Patients aged 70 years or above were included in the elderly group. RESULTS A total of 60 patients underwent laparoscopy-assisted gastrectomy over a 10-year period, with a predominance of male patients. There was no significant difference in the rate of overall surgical and non-surgical complications, in-hospital mortality, operation time and length of hospital stay, between the elderly and non-elderly groups. Univariate analysis, performed for risk factors relating to anastomotic leak and surgical complications, showed that age over 70 years and higher American Association of Anesthesiologists grades are associated with a higher, though not statistically significant, number of anastomotic leaks (P = 1.000 and P = 0.442, respectively) and surgical complications (P = 0.469 and P = 0.162, respectively). The recurrence rate within the first 3 years of surgery was significantly higher in the non-elderly group compared with the elderly group (Log Rank test, P = 0.002). There was no significant difference in survival between the two groups (Log Rank test, P = 0.619). CONCLUSIONS Laparoscopy-assisted gastrectomy is safe and feasible in an elderly population. There is a need for well-designed, prospective, randomised studies with quality of life data to inform our practice in future.

    Safe placement of the Verres needle or the primary trocar for establishment of pneumoperitoneum is the most critical step in laparoscopic procedure as it is associated with bowel, bladder and life threatening vascular injuries and embolism. In the last few decades many techniques and guidelines have been introduced to eliminate complications in creation of pneumoperitoneum. Classical closed technique (Verres needle) and the open classic technique (Hasson) are the most commonly used techniques for creation of pneumoperitoneum. To compare the rate of occurrence and nature of complications in open and closed laparoscopy during establishment of pneumoperitoneum in different surgical and gynaecological procedures. This was a comparative study conducted at three hospitals in Dibrugarh district, Assam, India from January 2012 to December 2014. Total 3000 cases were included in the study with 1500 cases of open laparoscopy and 1500 cases of closed laparoscopy. Complications occurring in both the groups were compared by using Fisher's-exact test. In closed laparoscopy group minor complications occurred in 80 (5.33%) and major complications in 20 (1.33%) cases. In open laparoscopy group minor complications were observed in 60 (4%) and major complications in 2 (0.13%). The p-value of the difference between the two groups for minor complications was 0.0834 and for major complications was 0.0001(significant). Open laparoscopy was seen to be better than closed laparoscopy in terms of not only the rate of occurrence of complications but also the nature and severity of the complications. This study is clinically relevant as there is no consensus for a particular method of safe entry in to the peritoneal cavity warranting the need for more research. Open technique can be performed in all cases irrespective of previous operative scar, suspected intra peritoneal adhesions or obesity. Favourable outcome may be achieved in closed technique in cases of normal BMI, absence of

    Full Text Available The present research provides analysis of results of preoperative examination of 680 patients with ectopic pregnancy depending on the range of surgical treatment. It has been shown that in case of progressive ectopic pregnancy the diagnostic significance of concentrations of human chorionic gonadotropin, transvaginal examination and laparos-copy depends on the duration of pregnancy. When the term of ectopic pregnancy is 3-4 weeks monitoring of p chorionic gonadotropin in blood serum (99.5%, transvaginal examination (58% and laparoscopy (78.5% are more informative. When the term of ectopic pregnancy is more than 4 weeks there is a high diagnostic value of monitoring p-subunit of chorionic gonadotropin (99.5%, transvaginal examination (68% and laparoscopy (99,5%. The research has proved that pregnancy period of 3-4 weeks is optimal for laparoscopy and other operations

    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.

    Laparoscopic reconstructive surgery is associated with a steep learning curve related to the use of two-dimensional (2D) vision and rigid instruments. With the advent of robotic surgery, three-dimensional (3D) vision, and articulated instruments, this learning curve has been facilitated. We present a hybrid alternative to robotic surgery, using laparoscopy with 3D vision and articulated shears. To compare outcomes of children undergoing pyeloplasty using 3D laparoscopy with articulated instruments with those undergoing the same surgery using standard laparoscopy with 2D vision and rigid instruments. Medical charts of 33 consecutive patients with ureteropelvic junction obstruction who underwent laparoscopic pyeloplasty by a single surgeon from 2006 to 2013 were reviewed in a retrospective manner. The current 3D cohort was compared with the previous 2D cohort. Data on age, weight, gender, side, operative time, dimension (2D = 19 patients, 3D = 8 patients), presence of a crossing vessel, length of hospital stay, and complication rate were compared between the two groups. Articulating shears were used for pelvotomy and spatulation of the ureter in the 3D group. Statistical tests included linear regression models and chi square tests for trends using STATA software. Operative time per case was decreased by an average of 48 min in the group undergoing 3D laparoscopic pyeloplasty compared with the group undergoing 2D laparoscopic pyeloplasty (p = 0.02) (Figure). Complication rate and length of hospital stay were not significantly affected by the use of 3D laparoscopy. These favorable results are in accordance with previous literature emphasizing the importance of 3D vision in faster and more precise execution of complex surgical maneuvers. The use of flexible instruments has also helped overcome the well-described delicate step of a dismembered pyeloplasty, namely the pelvotomy and ureteral spatulation. Limitations of this study are those inherent to the

    The comparative costs of laparoscopy and laparotomy in surgical resection of colorectal cancer, especially of the hospital provider, have not yet been assessed in the perspective of the Italian National Healthcare System. This paper aims to fill this gap by providing economic information on this research topic of growing relevance at a time of reduced healthcare budgets. Three Italian reference centres retrospectively provided from their databases data on 90 cases of laparotomy (OP) or laparoscopy (LAP) interventions for right colon (RCol), left colon/sigma (LCol) and rectum (Rec). Costs were retrieved according to phases of the in-hospital procedure: pre-operative, operative and post-operative phase, including diagnostic work-up, hospital length of stay, duration of intervention, theatre occupation time, type of anaesthesia, medical devices and drugs used and staff time throughout the management process from hospital admission to discharge. The cost estimation was carried out using a microcosting, bottom-up technique, and statistical analysis was carried out using appropriate techniques. The average cost of colorectal surgery was euro 10,539/patient (median euro 10,396) with rectum procedures being statistically more costly than colon procedures (mean Rec euro 12,562/patient versus LCol euro 9,054 and RCol euro 10,002; median euro 11,704 versus euro 8,941 and euro 9,513, respectively; p surgery is a costly procedure, and in-patient DRG tariffs are currently insufficient to cover the cost of its management for Italian hospital providers.

    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.

    Two hundred and fifty-two women scheduled to undergo laparoscopy were randomly assigned to a Verres needle or direct insertion group. The groups were similar with respect to incidence of obesity, prior surgical treatment, indication for operation and level of training of the surgeon performing the procedure. There were no major complications associated with either technique. Minor complications (preperitoneal insufflation, failed entry or more than three attempts necessary to enter the peritoneal cavity with the trocar) were significantly more frequent (p Verres needle technique group. One hundred and thirteen of these patients underwent sterilization procedures. The mean times for performance of the laparoscopic procedure using the direct insertion and Verres needle techniques was 15.3 and 19.6 minutes, respectively. The time saved using the direct insertion technique is explained by a significant (p Verres needle techniques, respectively. We prefer the direct insertion technique for trocar placement because it has fewer minor complications and requires less operating time.

    C-reactive protein and procalcitonin are reliable early predictors of infection after colorectal surgery. However, the inflammatory response is lower after laparoscopy as compared to open surgery. This study analyzed whether a different cutoff value of inflammatory markers should be chosen according to the surgical approach. A prospective, observational study included consecutive patients undergoing elective colorectal surgery in three academic centers. All infections until postoperative day (POD) 30 were recorded. The inflammatory markers were analyzed daily until POD 4. Areas under the ROC curve and diagnostic values were calculated in order to assess their accuracy as a predictor of intra-abdominal infection. Five-hundred-one patients were included. The incidence of intra-abdominal infection was 11.8%. The median levels of C-reactive protein (CRP) and procalcitonin (PCT) were lower in the laparoscopy group at each postoperative day (p laparoscopy group (p = 0.0036) but were not different in patients presenting with intra-abdominal infections (p = 0.3243). In the laparoscopy group, CRP at POD 4 was the most accurate predictor of overall and intra-abdominal infection (AUC = 0.775). With a cutoff of 100 mg/L, it yielded 95.7% negative predictive value, 75% sensitivity, and 70.3% specificity for the detection of intra-abdominal infection. The impact of infection on inflammatory markers is more important than that of the surgical approach. Defining a specific cutoff value for early discharge according to the surgical approach is not justified. A patient with CRP values lower than 100 mg/L on POD 4 can be safely discharged.

    Objective: To evaluate the role of laparoscopic cholecystectomy in acute cholecystitis and establish the out-comes of this treatment modality at North Oakland Medical Centers. Methods: This was a retrospective analysis over a three-year period (January 1, 1994 to December 31, 1996), per-formed at a University-affiliated urban teaching hospital, North Oakland Medical Centers, Pontiac, Michigan. Five hundred and fifty-seven patients underwent surgical treatment for gallbladder disease; 88 patients had acute cholecystitis, and 469 patients had chronic cholecystitis. Acute cholecystitis patients underwent surgery within 72 hours of the onset of symptoms; the patient's selection for laparoscopic cholecystectomy or open cholecystectomy depended on severity of disease, comorbid factors and surgeon's preference. The parameters of age, gender, operating (OR) time, length of stay, complications, conversion rates from laparoscopic cholecystectomy to open cholecystectomy, and cost were compared in patients who underwent laparoscopic cholecystectomy and/or open cholecystectomy. Results: Patients chosen to undergo laparoscopic cholecystectomy for acute cholecystitis tended to be younger females. Patients treated with laparoscopic cholecystectomy for acute cholecystitis had shorter OR times and LOS compared to patients treated with open cholecystectomy for acute cholecystitis. Conversion rates (CR) were 22% in acute cholecystitis and 5.5% in chronic cholecystitis during the study period; CR diminished considerably between the first and third year. Complications were also lower in patients who underwent laparoscopic cholecystectomy vs. open cholecystectomy. Conclusions: Laparoscopic cholecystectomy appears to be a reliable, safe, and cost-effective treatment modality for acute cholecystitis; however, the surgical approach should be cautionary because of the spectrum of potential technical hazards. CR is improving as surgeons gain experience. PMID:10444011

  17. Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions.

    Full Text Available Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber may act as a rare intermediate host, and so unscreened wild caught individuals may pose a potential risk of introducing this parasite to disease-free countries through translocation programs. There is currently no single definitive ante-mortem diagnostic test in intermediate hosts. An effective non-lethal diagnostic, feasible under field condition would be helpful to minimise parasite establishment risk, where indiscriminate culling is to be avoided. This study screened live beavers (captive, n = 18 or wild-trapped in Scotland, n = 12 and beaver cadavers (wild Scotland, n = 4 or Bavaria, n = 11, for the presence of E. multilocularis. Ultrasonography in combination with minimally invasive surgical examination of the abdomen by laparoscopy was viable under field conditions for real-time evaluation in beavers. Laparoscopy alone does not allow the operator to visualize the parenchyma of organs such as the liver, or inside the lumen of the gastrointestinal tract, hence the advantage of its combination with abdominal ultrasonography. All live beavers and Scottish cadavers were largely unremarkable in their haematology and serum biochemistry with no values suspicious for liver pathology or potentially indicative of E. multilocularis infection. This correlated well with ultrasound, laparoscopy, and immunoblotting, which were unremarkable in these individuals. Two wild Bavarian individuals were suspected E. multilocularis positive at post-mortem, through the presence of hepatic cysts. Sensitivity and specificity of a combination of laparoscopy and abdominal ultrasonography in the detection of parasitic liver cyst lesions was 100% in the subset of cadavers (95%Confidence Intervals 34.24-100%, and 86.7-100% respectively. For abdominal ultrasonography alone sensitivity was only 50% (95%CI 9

    Robotic surgery is a conceptual fusion of the conventional open surgery and the minimally invasive laparoscopic surgery. We reviewed the current role of robotic-assisted laparoscopy in the field of reproductive surgery by a literature search in PubMed database. We analyzed the reported advantages and limitations of the use of robotics in reproductive surgeries like myomectomy, tubal reanastomosis, endometriosis, ovarian tissue cryopreservation, and ovarian transposition. Overall, robotic assistance in reproductive surgery resulted in decreased blood loss, less post-operative pain, shorter hospital stay, and faster convalescence, whereas reproductive outcomes were similar to open/laparoscopic approaches. The main drawbacks of robotic surgery were higher cost and longer operating times. It is as safe and effective as the conventional laparoscopy and represents a reasonable alternate to abdominal approach. Procedures that are technically challenging with the conventional laparoscopy can be performed with robotic assistance. It has advantages of improved visualization and Endowrist™ movements allowing precise suturing. This helps to overcome the limitations of laparoscopy, especially in complicated procedures, and may shorten the steep learning curve in minimal invasive surgery. Randomized controlled trials looking at both short- and long-term outcomes are warranted to strengthen the role of robotic surgery in the field of reproductive surgery.

    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.

    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.

    A bezoar is a collection of indigestible material found in the alimentary canal, which can cause mechanical obstruction of the gastrointestinal tract. Phytobezoar is a variant composed of mostly plant material and indigestible fiber. Phytobezoar is a rare cause of small bowel obstruction (SBO) and happens more commonly in patients with risk factors predisposing to impaired gastrointestinal motility. We present a rare case of SBO secondary to phytobezoar in a 60-year-old female patient with type 2 diabetes. There was no prior history of any abdominal surgery. The abdominal computed tomography (CT) scan was inconclusive. Laparoscopy was found to be an effective diagnostic and therapeutic procedure in this patient.

    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

    Laparoscopic skills training is an essential component of general surgery training. This study proposes the use of three-dimensional (3D) laparoscopy as the initial training tool for beginners to shorten the learning curve. This study evaluates the surgical performance and subjective experience of junior and senior trainees with 3D versus two-dimensional laparoscopy. Peg transfer task was used as the objective time measurement. A subjective evaluation of the 2 systems using a questionnaire was also used. The mean difference in the juniors was 16.33 seconds, while in the seniors it was only 3.46 seconds (P = .036). The time difference between groups was much smaller in the 3D than the two-dimensional (P = .14 vs .02) laparoscopy. In the subjective evaluation, the novice group also scored significantly higher for the 3D system in the bimanual dexterity category (P = .004, .007). Our study demonstrates the feasibility of using 3D laparoscopy for laparoscopic skills training in novices. Copyright © 2015 Elsevier Inc. All rights reserved.

    To study the feasibility, safety, and short-/long-term outcomes of laparoscopy-assisted right hemicolectomy with D3 lymphadenectomy for colon cancer. The clinical data of 177 cases that underwent laparoscopy-assisted radical right hemicolectomy with D3 lymphadenectomy for colon cancer between Jun 2003 and Sep 2010 was collected; the safety of operation, status of recovery, complication, oncological outcomes, and results of short-/long-term follow-up were analyzed. No case died in this study; five cases (2.82 %) were converted to open surgery. Four cases (2.26 %) underwent hand-assisted laparoscopic right hemicolectomy. The average operation time was 133 ± 36 min, and the blood loss was 94 ± 34 ml. The average time for passage of flatus, liquid food eating, and hospitalization were 2.1 ± 0.7, 3.2 ± 0.5, and 10.4 ± 2.7 day, respectively. The total number of lymph nodes removed was 15.2 ± 10.1. Postoperative complications were observed in 23 of 177 patients (12.99 %). The median follow-up period was 54 months; port-site recurrence was observed in one patient; local recurrence was found in five cases (2.82 %); distant metastasis was found in 21 cases (11.86 %). The cumulative overall survival of all stages at 12, 36, 60, and 72 months was 97.18 %, 83.73 %, 70.37 %, and 68.99 %, respectively. The cancer-specific survival was 98.73 % (12 months), 87.81 % (36 months), and 80.17 % (60 months). Laparoscopy-assisted right hemicolectomy with D3 lymphadenectomy can be successfully performed for right colon cancer with the advantages of minimally invasive surgery. Moreover, the results implied appropriate short- and long-term outcomes.

    Laparoscopic colectomy is increasingly being adopted for the treatment of colon cancer; however, the long-term effectiveness of this approach in a real-world clinical setting has yet to be verified. This study aims to compare the effectiveness and costs associated with laparoscopic and open colectomy from the perspective of the National Health Insurance (NHI) system in Taiwan. A nationwide population-based colon cancer cohort was observed by linking the Taiwan Cancer Registry, claims data from NHI system, and the National Death Registry. Adult patients with Stage I to Stage III colon cancer who underwent primary cancer resection using either laparoscopy or open colectomy between 2009 and 2011 were included. A propensity score-matched cohort (1745 pairs) was applied to examine three clinical endpoints: overall survival, recurrence-free survival, and disease-free survival within 2 years after the operation. To comply with the perspective as well as the analytic horizon of the study, we limited the research to NHI claims from the study population for the corresponding time period. The health outcomes and net monetary benefits were verified by multivariate mixed-effect models. This analysis revealed that laparoscopy resulted in longer overall survival (adjusted difference 16.8 days, 95 % CI 7.3-26.2), recurrence-free survival (16.8 days, 5.0-28.6) and disease-free survival (26.4 days, 7.4-45.4), compared to open colectomy at 2 years post-op. Laparoscopy also led to a significantly shorter length of stay (3.2 days, 2.4-3.9) and lower index hospitalization costs (US$ 455, 181-729) than open colectomy; however, no differences in costs were observed over the long term. Overall, laparoscopy was more cost-effective than open colectomy under various willingness-to-pay thresholds in the setting of the Taiwan NHI. The continued adoption of laparoscopy in primary curable colon cancer resection is expected to reduce health care costs over the short term while providing

    In recent years, staging laparoscopy has gained acceptance as part of the assessment of resectability of upper gastrointestinal (UGI) malignancies. Not infrequently, we encounter tumours that are either locally advanced; requiring neoadjuvant therapy or occult peritoneal disease that requires palliation. In all these cases, the establishment of enteral feeding during staging laparoscopy is important for patients' nutrition. This review describes our technique of performing laparoscopic feeding jejunostomy and the clinical outcomes. The medical records of all patients who underwent laparoscopic feeding jejunostomy following staging laparoscopy for UGI malignancies between January 2010 and July 2015 were retrospectively reviewed. The data included patient demographics, operative technique and clinical outcomes. Fifteen patients (11 males) had feeding jejunostomy done when staging laparoscopy showed unresectable UGI maligancy. Eight (53.3%) had gastric carcinoma, four (26.7%) had oesophageal carcinoma and three (20%) had cardio-oesophageal junction carcinoma. The mean age was 63.3 ± 7.3 years. Mean operative time was 66.0 ± 7.4 min. Mean postoperative stay was 5.6 ± 2.2 days. Laparoscopic feeding jejunostomy was performed without intra-operative complications. There were no major complications requiring reoperation but four patients had excoriation at the T-tube site and three patients had tube dislodgement which required bedside replacement of the feeding tube. The mean duration of feeding tube was 127.3 ± 99.6 days. Laparoscopic feeding jejunostomy is an important adjunct to staging laparoscopy that can be performed safely with low morbidity. Meticulous attention to surgical techniques is the cornerstone of success.

    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 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

    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 strengths of surgical laparoscopy compared to laparotomy include shorter hospitalization, reduction in post-operative pain and adhesions, and better cosmetic outcomes. Since 2008, Single Port Access Laparoscopy (SPAL) has been used in order to offer additional cosmetic benefits and to further reduce post-operative morbidity. The aim of this study was to assess the feasibility of a subtotal hysterectomy using SPAL technique, as well as the benefits and the limitations of this technique. Retrospective series of 15 women managed between September 2010 and February 2013 at our university tertiary referral center by subtotal hysterectomy using SPAL technique for benign pathologies. Twelve of the 15 procedures were performed by SPAL alone. Three conversions to classic laparoscopy were required for a large uterus (1 case) or major pelvic adhesions (2 cases). Postoperative complications were a bladder injury, a subumbilical hematoma and transcervical fragmentation of a uterus with a low-grade sarcoma. Mean operative time was 85.4 minutes (50-170). Postoperative hospitalization was of 2 days in average. The rate of patient satisfaction at 16-month follow-up was 9.2/10. Subtotal hysterectomy using SPAL technique is safe and feasible. Successful procedure requires accurate selection of patients taking into account main limitations, such as uterus weight, patient's BMI and abdominal surgical history. Notwithstanding, SPAL technique can be seen as technical progress. Celsius.

    Laparoscopy is a reliable imaging method to examine the liver. However, due to the limited field of view, a lot of experience is required from the surgeon to interpret the observed anatomy. Reconstruction of organ surfaces provide valuable additional information to the surgeon for a reliable diagnosis. Without an additional external tracking system the structure can be recovered from feature correspondences between different frames. In laparoscopic images blurred frames, specular reflections and inhomogeneous illumination make feature tracking a challenging task. We propose an ego-motion estimation system for minimal invasive laparoscopy that can cope with specular reflection, inhomogeneous illumination and blurred frames. To obtain robust feature correspondence, the approach combines SIFT and specular reflection segmentation with a multi-frame tracking scheme. The calibrated five-point algorithm is used with the MSAC robust estimator to compute the motion of the endoscope from multi-frame correspondence. The algorithm is evaluated using endoscopic videos of a phantom. The small incisions and the rigid endoscope limit the motion in minimal invasive laparoscopy. These limitations are considered in our evaluation and are used to analyze the accuracy of pose estimation that can be achieved by our approach. The endoscope is moved by a robotic system and the ground truth motion is recorded. The evaluation on typical endoscopic motion gives precise results and demonstrates the practicability of the proposed pose estimation system.

    Gangrenous cholecystitis (GC) is a rare and severe condition requiring immediate cholecystectomy. The aim of this study was to compare outcomes of laparoscopic cholecystectomy with open cholecystectomy in patients with GC. The records of 278 patients with GC who underwent cholecystectomy, for acute cholecystitis were compared with those of 531 patients with nongangrenous cholecystitis. In patients with GC, the outcomes of laparoscopic cholecystectomy were also compared with the outcomes of open cholecystectomy. Multivariate analysis demonstrated an independent association of diabetes mellitus, temperature, muscle rigidity on examination, white cell blood count, gallbladder wall thickening, gallbladder wall interruption, detection of pericholecystic exudate on ultrasonography, with the development of acute GC. The rate of conversions in the GC group was higher than in nongangrenous cholecystitis group. In patients with GC morbidity did not differ between patients operated using laparoscopic technique or open technique. Total and postoperative hospital stays were shorter in patients operated using laparoscopic technique. Laparoscopic cholecystectomy is a safe procedure in patients with GC. Although the conversion rate to open surgery was elevated, the number of other complications was comparable to open surgery. Laparoscopic cholecystectomy significantly reduced total hospital stays and medical costs.

    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.

    Robert's uterus is a unique malformation, described as a septate uterus with a non-communicating hemicavity, consisting of a blind uterine horn usually with unilateral hematometra, a contralateral unicornuate uterine cavity and a normally shaped external uterine fundus. The main symptom in affected young women is pelvic pain that becomes intensified near menses. We describe the case of a 22-year-old woman who was referred for diagnostic assessment and treatment of a congenital uterine anomaly. We used three-dimensional sonohysterography with volume-contrast imaging, HDLive rendering mode and automatic volume calculation (SonoHysteroAVC) for the diagnosis, surgical planning and postoperative evaluation. These imaging techniques provided a complete understanding of the internal and external uterine structures, enabling us to perform a minimally invasive hysteroscopic metroplasty, guided by transrectal ultrasound, and therefore avoiding the need for laparotomy/laparoscopy. The outcome of treatment was considered satisfactory; menstruation ceased to be painful and, after two hysteroscopic procedures, the communicating 0.3-cm 3 hemicavity was visualized as a 3.6-cm 3 normalized uterine cavity using the same imaging techniques. The findings of this case report raise questions about the embryological origin of Robert's uterus, the suitability of current classification systems, and the role of more invasive approaches (laparoscopy/laparotomy) and surgical procedures (horn resection/endometrectomy) that do not aim to improve uterine cavity shape and volume in women with this condition.

    To evaluate the impact of gynecologic laparoscopy courses on the participants' laparoscopy practice. We conducted 5 repeated laparoscopy courses between 2008 and 2012 at the United Arab Emirates University in Al Ain, United Arab Emirates, so as to enhance performance in the operating room. An electronic questionnaire was sent to all participants from each of the courses to evaluate the impact of course attendance on clinical practice. Of 70 participants who were approached to complete the online questionnaire, 38 (54.3%) responded. The majority were female (94.7%) and specialists (65.8%). Half the participants (50.0%) thought they would probably not have started performing laparoscopy without having attended the course. Of the participants, 18.4% thought that their operating skills had greatly improved, 63.2% felt that their operating skills had improved moderately to a lot, and 6/12 participants who had not been performing laparoscopy before attendance of the course began doing so. Overall, the course had no significant impact on the participants' performance of laparoscopy (P=0.51, McNemar test), but the proportion of participants who performed level II laparoscopy was significantly increased after course attendance (10.5% versus 47.4%; P=0.001, McNemar test). Gynecologic laparoscopy courses encourage gynecologists to use laparoscopy in clinical practice. © 2013.

    Full Text Available Introduction: 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. Materials And Methods: 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. Results: 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. Conclusion: 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

    Port insertion is a high-risk period during laparoscopy. The French Gynecologist and Obstetricians College (CNGOF) published recommendations in 2010 to minimize those risks. The aim of our analysis was to establish the accidents' circumstances and consequences and to determine if those incidents could have been depending on whether recommendations had been respected or not. Gynerisq is an approved organism by the Haute Autorité de santé (HAS). Its mission is to evaluate and improve practices by a risk management centered approach. We analysed incidents reported by Gynerisq's adherents in an experience report database. Above 114 incidents analysed in the Gynerisq's database, we reported 31 bowel injuries. Those injuries occurred for 77.4% (24/31) during planned interventions. For 32.3% of the cases (10/31), interventions were judged complex by the surgeons. A total of 54.8% (17/31) of the patients had a history of laparotomy. Above 27 injuries occurred during Veress needle or open laparoscopy, 17 could have been avoided regarding to the surgeon. The causes reported were in 10 cases that the recommendations had not been respected, in 2 cases another cause and in 5 cases no causes were given to explain the incident. Our analysis shows that bowel injuries after port insertion, in open laparoscopy or Veress needle use, do not seem to occur only in an emergency context or during complicated interventions. However, most of the incidents occurred for patients with risk factors. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    This meta-analysis aimed to evaluate the prognosis and recurrence of apparent early-stage ovarian tumors treated with laparoscopy compared with laparotomy. Clinical studies published in English were retrieved from the computerized databases Medline and Embase. A meta-analysis was performed to investigate the differences in the efficacy and safety of laparoscopy versus laparotomy in terms of postoperative complications, lengths of hospital stay, recurrence rates, and disease-free survival times using the random effects model. The studies were independently reviewed by two investigators. Data from the eligible studies were extracted, and the meta-analysis was performed using the Comprehensive Meta-Analysis program, version 2 (CMA-2; Biostat, Englewood, NJ, USA). A total of 8 studies were included in the analysis. The results showed that laparoscopic surgery was significantly associated with lower rates of complications (OR = 0.433, P = 0.019) and shorter postoperative hospital stays (weighted mean difference [WMD] = −0.974, P < 0.001). There was no significant difference in the rates of recurrence (OR = 0.707, P = 0.521) between patients with apparent early-stage ovarian tumors who were treated using laparoscopy and those who underwent laparotomy. No publication bias was detected. Laparoscopic surgery shows favorable prognostic outcomes in terms of postoperative complication rates and postoperative hospital stay durations. Further studies with longer follow-up periods are required to confirm recurrence and survival outcomes after laparoscopic surgery in patients with apparent early-stage ovarian tumors

    The surgical management of urolithiasis has undergone a remarkable clinical evolution over the past three decades. The once common practice of open stone surgery has nearly been relegated to historical interest by modern technology. The introduction of minimally invasive techniques, laparoscopy and robot-assisted surgery, have emerged to complete the urologist's armamentarium. The benefits to patients when other endourologic procedures have failed include less pain, shorter hospitalization and convalescence, and improved cosmesis. This chapter explores the historical shift from open to minimally invasive management for stone disease and the unique risks and outcomes associated with these procedures in modern urology.

  16. Treatment of chronic recurrent abdominal pain: laparoscopy or hypnosis?

    Science.gov (United States)

    Galili, Offer; Shaoul, Ron; Mogilner, Jorge

    2009-02-01

    Functional chronic recurrent abdominal pain (FCRAP) is long lasting, intermittent, or constant pain affecting 15-30% of children ages 4-18 and presents a diagnostic and treatment challenge to the physician. The predictive value of diagnostic tests is questionable, and studies of the treatment of chronic abdominal pain show inconclusive evidence regarding diet regimens as well as medical and surgical treatments. However, there is evidence that cognitive-behavioral therapy may be useful in improving pain and disability outcome. Increasing the understanding of the neural-pain pathways and research in cognitive modulation of pain led to the application of behavioral strategies in children with FCRAP with variable success. However, the use of hypnotherapy in children with recurrent abdominal pain is not common. During the last 3 years, we have implemented hypnosis as the preferred treatment for patients with FCRAP. In the current study, we aimed to summarize our experience with hypnosis for the treatment of FCRAP in children. Twenty patients who met the criteria for FCRAP were candidates for hypnosis. Hypnosis or imagery was offered to the families, of whom 3 refused. Seventeen patients underwent just one single session of hypnosis. A possible nonorganic etiology for the abdominal pain was revealed in all cases. In 14 adolescents, all clinical symptoms resolved. Hypnosis was not effective in 3 cases, in whom secondary gain was probably responsible for their symptoms. No side effects have been noted during and after the study. Follow-up was available for a period of 4-24 months. Although effective in the management of acute pain and distress in pediatric cancer patients, the use of hypnotherapy in children with FCRAP is not a common practice. The current study highly supports the use of hypnosis as a part of the biobehavioral approach for this dilemma.

    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

    In children with a poorly functioning kidney due to vesicoureteral reflux (VUR) or ureteropelvic junction obstruction, management is by nephrectomy with total or proximal ureterectomy. The complete removal of all the ureter minimizes the risk of future morbidity associated with the distal ureteral stump (DUS), including febrile urinary tract infections (UTIs), lower quadrant pain and hematuria, the so-called ureteral stump syndrome. To assess the outcome of the DUS after nephroureterectomy, we analyzed our recent experience of nephrectomy performed via retroperitoneoscopy and via laparoscopy. The records of 21 consecutive patients (median age 3.5 years, range 1-10 years) who underwent nephroureterectomy via laparoscopy or via retroperitoneoscopy were retrospectively reviewed for symptoms caused by DUS and their management. Nephrectomy was undertaken for a poorly functioning dysplastic (4), scarred from VUR (10) or hydronephrotic (7) kidney. In the laparoscopic group (11 pts), 6 cases required nephrectomy for reflux while 5 patients were operated for hydronephrotic or dysplastic non-functioning kidney. In the retroperitoneoscopic group (10 pts), nephrectomy was performed for reflux in 4 cases versus 6 patients affected by hydronephrotic or dysplastic non-functioning kidney. The patients were evaluated using ultrasound (US) to check DUS length and clinically to evaluate symptoms due to a symptomatic DUS. The average length of surgery was 50 min for laparoscopy and 80 min for retroperitoneoscopy. The average of follow-up was 5 years. The length of DUS after laparoscopic nephrectomy was shorter (range 3-7 mm, statistically significant) than the DUS after retroperitoneoscopy (range 2-5 cm) (p laparoscopy permits removal of all the ureter near the bladder dome, in children with non-functioning kidney due to VUR, it is advisable to always perform a laparoscopic rather than a retroperitoneoscopic nephrectomy to prevent problems related to a symptomatic DUS.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

    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

  3. Role of Laparoscopy in Management of Ectopic Pregnancy

    Full Text Available Ectopic pregnancy means implantation of fertilized ovum outside the endometrial lining of the uterus. It remains the leading cause of early pregnancy-related death. Delay in diagnosis and treatment puts the life of women at risk. Laparoscopic surgery is increasingly becoming the preferred approach for ectopic pregnancy management. Laparoscopic treatment in ectopic pregnancy raises question of safety and feasibility when compared to laparotomy. In this review article our objective is to summarize the role of laparoscopy in management of ectopic pregnancy in comparison to laparotomy. For this, a literature search was done by using Google and PubMed. The selected articles were analyzed on laparoscopic treatment outcomes such as surgery success rate, operating time, intraoperative and postoperative complications, hospital stay, future fertility, postoperative recurrent ectopic pregnancy, cost-effectiveness in comparison to laparotomy. After analyzing all selected articles, it can be concluded that the laparoscopic management of ectopic pregnancy is safe, effective, and economical in comparision to laparotomy. So, for the patients’ benefit, laparoscopy should be considered as the gold standard method in management of ectopic pregnancy and is worthy to be popularized in clinical practice.

    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.

    Marcello Barbosa Barros

    Full Text Available CONTEXT: Iatrogenic vascular problems due to laparoscopy are a well recognized problem and lead to significant repercussions. In this context, a ten-year review of cases topic is presented, based on experience gained while heading two important vascular surgery services. CASES: Five patients with vascular injuries during elective laparoscopy are described. These patients presented with seven lesions of iliac vessels. All cases were evaluated immediately and required laparotomy, provisional hemostasis and urgent attendance by a vascular surgeon. Direct suturing was performed in three cases. One aortoiliac bypass and one ilioiliac reversed venous graft were made. Venous lesions were sutured. One case of a point-like perforation of the small bowel was found. There were no deaths and no complications during the postoperative period. DISCUSSION: Important points on this subject are made, and advice is given. There needs to be immediate recognition of the vascular injury, and expert repair by a vascular surgeon is recommended, in order to significantly reduce the degree of complications.

    Laparoscopic hepatectomy provides the usual advantages of a minimally invasive surgery. This study presents a case of Fasciola hepatica infection that was successfully treated with laparoscopic hepatectomy. The patient was referred because of persistent fever and right hypochondralgia with a huge mass occupying the right lobe of the liver, which was detected by imaging analysis. Serologic tests indicated an F. hepatica infection. The patient underwent a laparoscopic resection because the anthelmintic agent, triclabendazole was not effective. During the surgical technique, 5 trocars were inserted. After liver mobilization, the Glissonian pedicles and right hepatic veins were safely taped. A Penrose drain was placed behind the liver for a liver-hanging maneuver. A liver parenchymal transection was performed through an 8 cm handport site using a dissecting sealer (TissueLink Medical) after precoagulating its superficial layer by microtaze. Glissonian pedicles and the right hepatic vein were divided using an endolinear stapler (endcutter 45, Ethicon). Finally, the resected specimen was extracted from the handport. The surgical time was 450 minutes and the surgical blood loss was 370 mL. The patient was discharged 10 days after the surgery with an uneventful postoperative course. The laparoscopy-assisted hepatectomy in this case was beneficial for the patient's quality of life as a minimally invasive operation with a high degree of safety.

    Laparoscopy-assisted distal gastrectomy (LADG) has been widely accepted for the treatment for early gastric cancer. Obesity is a rapidly growing epidemic, and the number of obese patients with gastric cancer is increasing, but the impact of visceral fat (VF) accumulation on laparoscopic gastric surgery remains unknown. The aim of the present study was to determine the impact of VF accumulation on LADG. The medical charts of 30 patients who underwent LADG for early gastric cancer in our hospital between November 2000 and November 2006 were analyzed retrospectively. The patients were divided into two groups on the basis of VF accumulation measured on cross-sectional computed tomography at the level of the umbilicus. Twelve patients had high VF accumulation (> or =100 cm2) and 18 had low VF accumulation (group had a significantly longer operation time and significantly more operative blood loss than the low-VF-accumulation group. There was no significant difference in the rate of postoperative complications or conversion to open laparotomy between the two groups. There were no operative deaths or requirements for blood transfusion in either group. VF accumulation was significantly correlated with operative difficulties during LADG. Although LADG was as safe for patients with high VF accumulation as for patients with low VF accumulation, a longer operative time and more operative blood loss were observed in patients with high VF accumulation. VF accumulation appears to be a possible risk factor in LADG and should be considered when making a decision about treating early gastric cancer with LADG.

    Full Text Available Tumor size smaller than 4 cm as an indication for surgical treatment of incidentaloma is still a subject of discussion. Our aim was the estimation of the incidence of malignancy and analysis of treatment outcomes in patients with incidentaloma smaller than 4 cm in comparison to bigger lesions. 132 patients who underwent laparoscopic adrenalectomy for nonsecreting tumors were divided into two groups: group 1 (55 pts., size  40 mm. Operation parameters and histopathological results were analyzed. No differences in group characteristics, mean operation time, and estimated blood loss were noted. Complications in groups 1 and 2 occurred in 3.6% and 5.2% of patients, respectively (P=0.67. Malignancy in groups 1 and 2 was present in 1 and 6 patients, respectively (P=0.13. Potentially malignant lesions were identified in 4 patients in group 1 and 4 patients in group 2 (P=0.39. The results do not allow for straightforward recommendations for surgical treatment of smaller adrenal tumors. The safety of laparoscopy and minimal, but impossible to omit, risk of malignancy support decisions for surgery. On the other hand, the risk of malignancy in smaller adrenal tumors is lower than surgical complications, which provides an important argument against surgery.

    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.

    Living pancreas transplantation plays an important role in the treatment of patients with severe type 1 diabetes. However, pancreatectomy is very invasive for the donor, and less-invasive surgical procedures are needed. Although some reports have described hand-assisted laparoscopic surgery for distal pancreatectomy in living-donor operations, less-invasive laparoscopy-assisted (LA) procedures are expected to increase the donor pool. We herein report the outcomes of four cases of LA spleen-preserving distal pancreatectomy (Warshaw technique [WT]) in living pancreas donors. Four living pancreas donors underwent LA-WT at our institution from September 2010 to January 2013. All donors fulfilled the donor criteria established by the Japan Society for Pancreas and Islet Transplantation. The median donor age was 54 years. Two donors underwent left nephrectomy in addition to LA-WT for simultaneous pancreas-kidney transplantation. The median donor operation time for pancreatectomy was 340.5 minutes. The median pancreas warm ischemic time was 3 minutes. The median donor blood loss was 246 g. All recipients immediately achieved insulin independence. One donor required reoperation because of obstructive ileus resulting from a port-site hernia. Another donor developed a pancreatic fistula (International Study Group of Pancreatic Fistula grade B), which was controlled with conservative management. After a maximum follow-up of 73 months, no clinically relevant adverse events had occurred. These results were comparable with those of previous studies concerning living-donor pancreas transplantation. The LA-WT is a safe and acceptable operation for living-donor pancreas transplantation.

    Aim: To investigate the computed tomography (CT) imaging features of omental infarction in patients who underwent laparoscopy-assisted gastrectomy (LAG) for gastric cancer. Materials and methods: A retrospective study was performed on 390 patients who underwent LAG for gastric cancer. Two radiologists evaluated the CT images for the presence of omental infarction. The CT pattern was characterized at initial presentation and the evolutional changes were evaluated. The initial CT appearance of omental infarctions were categorized into the following four types: type 1 (ill-defined, heterogeneous, fat density lesion); type 2 (well-defined fat density lesion with rim enhancement); type 3 (well-defined heterogeneous lesion with fat component); and type 4 (well-defined heterogeneous lesion without a fat component). Results: Of the 390 patients involved, nine patients (2.3%; six male and three female with a mean age of 57 years) were diagnosed with omental infarction. Infarctions averaged 4.1 cm (range 2-7.3 cm) in diameter. Among nine patients with omental infarction, two patients had type 1 lesions, two had type 2, two had type 3, and three type 4. All infarctions became smaller and better defined with evolution. In two patients who presented with type 1 lesions on initial CT, each lesion was progressed to type 2 and type 3 on follow-up CT. In two patients with type 3 lesions on initial CT, the lesions changed to type 4 on follow-up CT. Conclusion: An awareness of the various CT features and evolutional changes in omental infarction after LAG for gastric cancer can help ensure the correct diagnosis and to avoid misdiagnosis for omental implants.

    To compare the clinical effect of transumbilical single-port laparoscopy combined with improved double hernia needles with that of traditional open surgery in the treatment of hydrocele in children. We retrospectively analyzed 35 cases (54 sides) of pediatric hydrocele treated by transumbilical single-port laparoscopy combined with improved double hernia needles (laparoscopy group). We recorded the operation time, intraoperative blood loss, hospital stay, scrotal edema, and postoperative complications and compared them with those of another 46 cases (58 sides) treated by traditional open surgery (open surgery group) during the same period. The laparoscopy group showed a significantly shorter operation time, less intraoperative blood loss, milder scrotal edema, and fewer hospital days than the open surgery group (all P0.05). Subcutaneous emphysema developed in 2 patients in the laparoscopy group, which disappeared after 1-3 days of oxygen inhalation and other symptomatic treatment, while scrotal hematoma occurred in 1 and incision fat liquefaction in 2 patients in the open surgery group 3 days postoperatively, which healed after debridement suture and daily dressing, respectively. The patients were followed up for 3-6 months, which revealed no late complications in the laparoscopy group but 1 case of unilateral recurrence and 2 cases of offside recurrence in the open surgery group, all cured by laparoscopic internal ring ligation. Transumbilical single-port laparoscopy combined with improved double hernia needles is superior to traditional open surgery for the treatment of pediatric hydrocele and therefore deserves clinical generalization.

    Biliary lithiasis is an endemic condition in both Western and Eastern countries, in some studies affecting 20% of the general population. In up to 20% of cases, gallbladder stones are associated with common bile duct stones (CBDS), which are asymptomatic in up to one half of cases. Despite the wide variety of examinations and techniques available nowadays, two main open issues remain without a clear answer: how to cost-effectively diagnose CBDS and, when they are finally found, how to deal with them. CBDS diagnosis and management has radically changed over the last 30 years, following the dramatic diffusion of imaging, including endoscopic ultrasound (EUS) and magnetic resonance cholangiography (MRC), endoscopy and laparoscopy. Since accuracy, invasiveness, potential therapeutic use and cost-effectiveness of imaging techniques used to identify CBDS increase together in a parallel way, the concept of “risk of carrying CBDS” has become pivotal to identifying the most appropriate management of a specific patient in order to avoid the risk of “under-studying” by poor diagnostic work up or “over-studying” by excessively invasive examinations. The risk of carrying CBDS is deduced by symptoms, liver/pancreas serology and ultrasound. “Low risk” patients do not require further examination before laparoscopic cholecystectomy. Two main “philosophical approaches” face each other for patients with an “intermediate to high risk” of carrying CBDS: on one hand, the “laparoscopy-first” approach, which mainly relies on intraoperative cholangiography for diagnosis and laparoscopic common bile duct exploration for treatment, and, on the other hand, the “endoscopy-first” attitude, variously referring to MRC, EUS and/or endoscopic retrograde cholangiography for diagnosis and endoscopic sphincterotomy for management. Concerning CBDS diagnosis, intraoperative cholangiography, EUS and MRC are reported to have similar results. Regarding management, the recent

    To determine the interest of using robotic laparoscopic surgery in the management of female infertility, we reviewed our own activity and searched the Medline database for publications on robotic technology in infertility surgery, with the use of the following search words: robotic laparoscopy, tubal anastomosis, myomectomy, deep infiltrating endometriosis, and adnexal surgery. Robot-assisted laparoscopic surgery has seen rapid progression over the past few years. It has been mostly used for myomectomy, proximal tubal reanastomosis, and deep endometriosis surgery. Despite its increased range of indications, no randomized control studies are available. The place of robotic surgery in the management of infertility remains undetermined.

    This paper describes the significance in human, scientific, and technical terms of the first experiment of robotic telesurgery effected between the Telerobotics Laboratory of the Politecnico di Milano and the Jet Propulsion Laboratory, NASA, in Pasadena California, on 7 July 1993. An Italian surgeon controlled from the U.S. A. an Italian robot in the Telerobotics Laboratory in such a way that the robot performed a biopsy, on a model containing the organs of a pig, carrying out an aspiration of organic material and two incisions for the commencement of the surgical operation of laparoscopy. Transmission was effected by means of a double satellite link with three stations -- one in Italy, one in New York and one in Pasadena -- and two geostationary satellites, the first over the Atlantic and the second over the United States.

    The results of preoperative pelvic examination and eventual ultrasound examination were correlated with the laparoscopic findings in 316 women with acute pelvic pain. The predictive values of normal and abnormal findings at pelvic examination were 46.9 and 82.1%, respectively. 42.1% of the women...... had ultrasound examination performed. This investigation showed to be helpful especially in patients with normal findings at pelvic examination. If ultrasonic findings were abnormal the results at laparoscopy were also abnormal in 90%. On the contrary, normal findings at ultrasound examination did...... not exclude abnormal pelvic findings. The predictive value of normal results at ultrasound examination was 50.0%. This discrepancy between ultrasonic and pelvic findings can be explained by the size of the pelvic masses.

  19. Technique of Intravesical Laparoscopy for Ureteric Reimplantation to Treat VUR

    Directory of Open Access Journals (Sweden)

    Atul A. Thakre

    2008-01-01

    Full Text Available The prevalence of vesicoureteral reflux (VUR has been estimated as 0.4 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 presenting our surgical technique: laparoscopic intravesical ureteric reimplantation is to highlight the use of laparoscopy to perform ureteric reimplantation for the management of pediatric VUR.

    While laparoscopy-assisted endoscopic retrograde cholangiopancreatography can be performed for the diagnosis and management of pancreaticobiliary diseases in patients with Roux-en-Y (RY) anatomy; the technical feasibility of performing laparoscopy-assisted endoscopic ultrasound (EUS) is unknown. In this report, we describe the technique for performing laparoscopy-assisted EUS in two patients with RY gastric bypass anatomy who presented with obstructive jaundice, abnormal liver function tests, and dilated biliary tree. While the examination was normal in one patient, EUS-guided fine needle aspiration of pancreatic head mass revealed adenocarcinoma in the other. Laparoscopic assisted EUS examination including FNA is feasible in Roux-en-Y surgical anatomy.

    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)

    Emergency abdominal surgery results in a high rate of post-operative complications and death. There are limited data describing the emergency surgical population in details. We aimed to give a detailed analyses of complications and mortality in a consecutive group of patients undergoing acute abdominal surgery over a 4-year period. This observational study was conducted between 2009 and 2013 at Copenhagen University Hospital Herlev, Denmark. All patients scheduled for emergency laparotomy or laparoscopy were included. Pre-, intra-, and post-operative data were collected from medical records. Complications were registered according to the Clavien-Dindo classification. Cox regression analysis was performed to identify risk factors for mortality. A total of 4,346 patients underwent emergency surgery, of whom 14 % had surgical complications and 23 % medical complications. The overall 30-day mortality was 8 % with 50 % of those in this group over 80 years of age. The 30-day mortality rates were 0.8 % (95 % CI 0.5-1.1) and 17 % (95 % CI 15.5-18.9), respectively, for the laparoscopy and the laparotomy groups. The overall death rate within 24 h of surgery was 21 %. Several risk factors for 30- and 90-day mortality were identified: age, ASA ≥3 (American Society of Anaesthesiologists physical status classification), performance score (Zubroed/WHOclassification), cirrhosis of the liver, chronic nephropathy, several medical conditions, and malignancy. Almost one in five patients died after emergency laparotomy, of whom one in five died within 24 h of surgery. Predictors for poor outcome were identified.

    Full Text Available Background. Ruptured ectopic pregnancy (REP is a common gynaecological emergency in resource-poor settings, where laparotomy is the standard treatment despite laparoscopic surgery being regarded as the optimal treatment. There is a lack of prospective randomised data comparing laparoscopic surgery with laparotomy in the surgical management of women with REP. Objective. To compare operative laparoscopy with laparotomy in women with REP. Methods. This was a randomised parallel study. One hundred and forty women with suspected REP were randomised to undergo operative laparoscopy or laparotomy. The outcome measures were operating time, hospital stay, pain scores and analgesic requirements, blood transfusion, time to return to work, and time to full recovery. Results. Operating time was significantly longer in the laparoscopy group (67.3 v. 30.5 minutes, p<0.001. Duration of hospital stay, pain scores and need for analgesia were significantly less in the laparoscopy group. Women in this group returned to work 8 days earlier and their time to full recovery was significantly shorter compared with those in the laparotomy group. Significantly more women undergoing laparotomy required blood transfusion than women in the laparoscopy group. In the latter group, 14.5% of women required blood transfusion compared with 26.5% in the laparotomy group (p=0.01. Conclusion. Operative laparoscopy in women treated for REP is feasible in a resource-poor setting and is associated with significantly less morbidity and a quicker return to economic activity.

    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 laparoscopy. Pegboard time was increased in both hands after SILS (P laparoscopy was close to reference slope, indicating there was more fatigue in biceps and deltoid muscles of both upper extremities in SILS group. NASA-TLX score was 73 ± 13.3 and 42 ± 19.5 in SILS and multiport laparoscopy, respectively (P 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.

    Benefits of laparoscopic surgery in the management of gastrointestinal fistula caused by Crohn disease need to be fully elucidated. We conducted this retrospective study to investigate the safety and feasibility and emphasize the advantages of laparoscopy compared with that of laparotomy for patients with gastrointestinal fistula caused by Crohn disease. A total of 1213 patients with gastrointestinal fistula in our center were screened, and 318 qualified patients were enrolled and divided into laparoscopy (n = 122) and laparotomy (n = 196) groups. Postoperative complications, length of hospital stay, systemic stress responses to surgery, postoperative mortality, and economic burden were collected and compared. A total of 125 laparoscopic interventions were performed with a conversion rate of 20.0%. Fifteen versus 84 postoperative complications were obtained in laparoscopy and laparotomy groups, respectively (P = 0.0033). Total hospitalization was 22.7 d and 38.0 d in laparoscopy and laparotomy groups, respectively (P laparoscopy was significantly lower than that to laparotomy. Reduced postoperative mortality (P = 0.0292) and postoperative cost (P = 0.0292) were observed in laparoscopy instead of laparotomy group. Laparoscopic approach is safe and feasible and could improve clinical outcome in gastrointestinal fistula patients with Crohn disease. Copyright © 2016 Elsevier Inc. All rights reserved.

    Abstract The aim of this study was to compare the long-term safety and efficacy of laparoscopic surgery and laparotomy for high-risk endometrial cancer (EC). A retrospective analysis based on our decade of clinical data of patients with high-risk EC who were comprehensively surgically staged by laparotomy or laparoscopy was performed. The surgical outcomes were compared between different approaches using propensity score matching (PSM). Eighty-one pairs of patients from the initial 220 enrolled ones were matched by PSM. The mean operative time is similar between laparotomy and laparoscopy groups (258 minutes vs. 253 minutes). The laparoscopy cohort has less blood loss (107 mL vs.414 mL, P laparoscopy (16.4) were significant less than that dissected by laparotomy (21.9). The 5- and 10-year survival rate for laparotomy were 89.2% and 75.8% compared with 85.3% and 85.3% for the laparoscopy. There was no significant difference in overall survival (P = 0.97). Laparoscopy is as effective as laparotomy in the long term and can be safely carried out in patients with high-risk EC for surgery treatment. PMID:26222865

    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

    To evaluate the technique and short-term results of intraperitoneal (IP) myomectomies. From January 1, 1990, to March 1, 1991, IP myomectomies were performed in all cases in which it appeared feasible. This study was conducted in a tertiary care center, the Port-Royal University Hospital. Among 49 consecutive patients with interstitial or subserous myomas, 6 patients with voluminous, multiple myomas had laparotomies. Intraperitoneal myomectomy was performed in 43 patients. The indication for laparoscopy was a pelvic mass in 29 cases, infertility in 13, and severe endometriosis in 1 case. Thermocoagulation or monopolar coagulation was used for the uterine incision. Myometrium and serosa were sutured in 23 of 43 patients. Myomas were removed through the suprapubic puncture site after fragmentation of large myomas. We evaluated the length of the procedures, blood loss, and postoperative course. Ninety-two myomas were removed laparoscopically. No complication was observed. In selected cases, IP myomectomy appears to be a safe technique with the advantages of laparoscopic surgery.

    Recent literature suggests that laparoscopic repair of ventral hernias may have very low recurrence rates. However, laparoscopy may not be feasible in certain situations. We describe an open technique that uses the tension-free retrofascial principles of laparoscopic repair without the need for subcutaneous flaps. Through an incision in the hernia, the peritoneum is entered and adhesions are taken down. A piece of DualMesh (W.L. Gore & Associates, Inc, Newark, Del) is trimmed to fit with a 5-cm circumferential overlap. A vertical incision is made in the mid portion of the mesh. The mesh is fixed in an intraperitoneal retrofascial position using GORE-TEX sutures (W.L. Gore & Associates, Inc). The sutures are brought through the abdominal wall using a laparoscopic suture passer and tied into place on one side of the mesh. That side is then tacked to the posterior fascia with a spiral tacking device. The other side is sutured into place in a similar fashion and then tacked to the fascia by passing the spiral tacking device through the incision in the mesh. The mesh incision is closed with a running GORE-TEX suture. The overlying tissues are closed in layers.

    To review the most recent literature and contemporary role of the use of porcine and chicken models in laparoscopic and robotic simulation exercises, for training and skill assessment. There are multiple types of the simulators which include mechanical, virtual reality, hybrid simulators and animal models. The recent literature has seen insurgence of several of such simulators, specifically the animate ones comprising porcine and chicken models. The different training models reported have evolved from generalized and simpler, to a more task dedicated and complex versions. Unlike in the past, the recent publications include analysis of these models incorporating different measures of validity assessment. On account of the natural tissue properties inherent to these porcine and chicken models, they are proving to be instrumental in acquisition of higher surgical skills such as dissection, suturing and use of energy sources, all of which are required in real-time clinical scenarios be it laparoscopy or robotic-assisted procedures. In-vivo training in the animal model continues to be, perhaps, the most sophisticated training method before resorting to real-time surgery.

  15. "Spaghetti Maneuver": A useful tool in pediatric laparoscopy - Our experience

    Full Text Available Aims: The laparoscopic "Spaghetti Maneuver" consists in holding an organ by its extremity with a grasper and rolling it up around the tool to keep the organ stable and facilitate its traction within a small space. We describe our experience with the "Spaghetti Maneuver" in some minimally invasive procedures. Materials and Methods: We successfully adopted this technique in 13 patients (5F : 8M aged between 6 and 14 years (average age, 10 on whom we performed 7 appendectomies, 2 ureteral reimplantation and 4 cholecystectomies. In all cases, after the first steps, the appendix, the gallbladder and the ureter were rolled around the grasper and easily isolated; hemostasis was thus induced and the organ was mobilized until removal during cholecystectomy and appendectomy, and before the reimplantation in case of ureteral reimplantation. Results: We found that this technique facilitated significantly the acts of holding, isolating and removing, when necessary, the structures involved, which remained constantly within the visual field of the operator. This allowed a very ergonomic work setting, overcoming the problem of the "blind" zone, which represents a dangerous and invisible area out of the operator′s control during laparoscopy. Moreover the isolation maneuvers resulted easier and reduced operating time. Conclusion: We think that this technique is easy to perform and very useful, because it facilitates the dissection of these organs, by harmonizing and stabilizing the force of traction exercised.

    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 Thirty patients with ovarian dermoid cysts removed by laparoscopic surgery were compared with 42 patients with ovarian dermoid cysts removed by laparotomy, with respect to the selection criteria, surgical procedures, operating time, intraoperative and postoperative complications, blood loss, and hospital stay. Although the operating time for unilateral cystectomy, unilateral salpingo-oophorectomy, and bilateral cystectomy performed by laparoscopic surgery was longer (120.3 ± 43.7 min, mean ± SD than those for the same procedures performed by laparotomy (73.9 ± 21.6 min, p < 0.01, we observed a learning curve with a remarkable declining tendency (linear regression model, p < 0.01. At the end of this study, the times taken for laparoscopic procedures were almost the same as those for laparotomy. Less blood loss (18.2 ± 1.7 ml versus 105.9 ± 84.3 ml, p < 0.01 and shorter hospital stay (5.9 ± 1.9 days versus 12.0 ± 2.9 days, p < 0.01 were also found to be advantages of laparoscopic surgery. This article discusses the technical procedures of laparoscopic surgery. The efficiency and safety of operative laparoscopy as an alternative access route for the management of ovarian dermoid cysts were recognized. We stress that strict criteria for selection of patients should always be followed and the necessity of retraining schedules for gynecologists and nursing staff in the speciality of laparoscopic surgery.

    Previous studies have suggested that patients with occult peritoneal metastases not seen on preoperative imaging have poor prognosis. In this study, we aim to evaluate the utility and impact of staging laparoscopy and peritoneal cytology in patients with gastric adenocarcinoma. A retrospective analysis of patients with gastric adenocarcinoma managed at two major metropolitan hospitals in Melbourne, Australia, between January 1999 and July 2010 was undertaken. The main outcome measures were the number of patients in whom laparoscopy and/or peritoneal cytology changed treatment intent, and the overall survival of patients with occult metastases detected by laparoscopy/cytology. Staging laparoscopy as an independent procedure was performed in 74.3% (148/199) of patients who had neither unequivocal metastases (M1) on preoperative imaging nor early T1 disease on endoscopic ultrasound. Laparoscopy/cytology detected occult metastases in 38 (25.6%) patients (27 macroscopic M1 and 11 microscopic M1 with positive peritoneal cytology only), leading to change in the treatment intent in 37 cases. The median overall survivals of patients with metastatic disease detected at staging laparoscopy (8.3 months, 95% confidence interval (CI) 5.4-16.5) or on peritoneal cytology (4.9 months, 95% CI 4.2-48) were as poor as those with M1 disease seen on preoperative imaging (6.7 months, 95% CI 4.2-8.9), P = 0.97. Laparoscopy and peritoneal cytology add incremental value to modern imaging in the staging of gastric adenocarcinomas by detecting occult metastatic disease. Their utility needs to be optimized to allow better treatment selection for gastric cancer patients. © 2013 The Authors. ANZ Journal of Surgery © 2013 Royal Australasian College of Surgeons.

    Following CT, guidelines for staging oesophageal and gastro-oesophageal junction (GOJ) cancer recommend endoscopic ultrasonography (EUS), PET-CT and laparoscopy for T3-T4 GOJ tumours. These recommendations are based on generic utilities, but it is unclear whether the test risk outweighs the potential benefit for some patients. This study sought to quantify investigation risks, benefits and utilities, in order to develop pragmatic, personalized staging recommendations. All patients with a histological diagnosis of oesophageal or GOJ cancer staged between May 2006 and July 2013 comprised a development set; those staged from July 2013 to July 2014 formed the prospective validation set. Probability thresholds of altering management were calculated and predictive factors identified. Algorithms and models (decision tree analysis, logistic regression, artificial neural networks) were validated internally and independently. Some 953 patients were staged following CT, by [(18) F]fluorodeoxyglucose PET-CT (918), EUS (798) and laparoscopy (458). Of these patients, 829 comprised the development set (800 PET-CT, 698 EUS, 397 laparoscopy) and 124 the validation set (118 PET-CT, 100 EUS, 61 laparoscopy). EUS utility in the 71.8 per cent of patients with T2-T4a disease on CT was minimal (0.4 per cent), its risk exceeding benefit. EUS was moderately accurate for pT1 N0 disease. A number of factors predicted metastases on PET-CT and laparoscopy, although none could inform an algorithm. PET-CT altered management in 23.0 per cent, and laparoscopy in 7.1 per cent, including those with T2 and distal oesophageal tumours. Although EUS provided additional information on T and N category, its risk outweighed potential benefit in patients with T2-T4a disease on CT. Laparoscopy seemed justified for distal oesophageal tumours of T2 or greater. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Laparoscopic surgery is widely used, and results in accelerated patient recovery time and hospital stay were compared with laparotomy. However, laparoscopic surgery is more challenging compared with open surgery, in part because surgeons must operate in a three-dimensional (3D) space through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception. To counter this problem, 3D imaging for laparoscopy was developed. A systematic review of the literature was performed to assess the effect of 3D laparoscopy. A systematic search of the literature was conducted to identify randomized controlled trials that compared 3D with 2D laparoscopy. The search was accomplished in accordance with the PRISMA guidelines using the PubMed, EMBASE, and The Cochrane Library electronic databases. No language or year of publication restrictions was applied. Data extracted were cohort size and characteristics, skill trained or operation performed, instrument used, outcome measures, and conclusions. Two independent authors performed the search and data extraction. Three hundred and forty articles were screened for eligibility, and 31 RCTs were included in the review. Three trials were carried out in a clinical setting, and 28 trials used a simulated setting. Time was used as an outcome measure in all of the trials, and number of errors was used in 19 out of 31 trials. Twenty-two out of 31 trials (71%) showed a reduction in performance time, and 12 out of 19 (63%) showed a significant reduction in error when using 3D compared to 2D. Overall, 3D laparoscopy appears to improve speed and reduce the number of performance errors when compared to 2D laparoscopy. Most studies to date assessed 3D laparoscopy in simulated settings, and the impact of 3D laparoscopy on clinical outcomes has yet to be examined.

    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

    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.

    To compare and analyze the clinical efficacy of laparoscopy combined with choledochoscopy, and laparoscopy combined with duodenoscopy, for cholelithiasis and choledocholithiasis. A total of 105 patients with cholelithiasis and choledocholithiasis from our hospital, from January 2014 to January 2015, were enrolled in this study. All patients weren given primary treatment. After obtaining consent from our hospital Ethics Committee and the patients, all 10529 cases were divided into two groups according to their time of admission. The observation group consisted of 59 cases and the control group consisted of 46 cases. The control group were treated by laparoscopy combined with duodenoscopy (cholecystectomy +ERCP+calculi extraction with an endoscope) and the observation group were treated by laparoscopy combined with choledochoscopy. We then compared the clinical efficacy between the two groups of patients. The success rate of the first surgery in the observation group, was higher than that in the control group. The time of surgery and intra-operative blood loss of the observation group were less than the control group. The differences had statistical significance p choledocholithiasis. Its treatment outcomes might be superior to laparoscopy combined with duodenoscopy.

    Background: Tubal disturbances often contribute to infertility. Conventional hysterosalpingography (HSG) is considered as standard in the assessment of the patency of the fallopian tubes, but requires ionizing radiation and is restricted to the imaging of endoluminal structures. Purpose: To evaluate dynamic magnetic resonance-HSG (dMR-HSG) in the diagnostic work-up in patients with infertility. Material and Methods: Thirty-seven consecutive infertile women underwent dMR-HSG: 20 ml of gadolinium-polyvidone solution (18.4 mM Dotarem 1:20 with polyvidone) were injected intracervically through a 5-Charriere balloon catheter while acquiring five consecutive flash-3D T1-weighted MR sequences with fat saturation. Two experienced readers assessed image quality and anatomic-pathologic correlations prospectively. The relevance of results was evaluated in the clinical context of each patient. Patient comfort was evaluated with a standardized questionnaire. Results: dMR-HSG was successfully completed in 33/37 patient with an average study time of 45 min. In 4 of 37 patients the catheter became dislodged during the examination, resulting in two complete diagnostic failures. Failure in another two patients was due to preliminary termination because of excessive pain and discomfort during the application of the contrast solution. The uterine cavity was completely visualized and bilateral fallopian tube patency was confirmed by dMR-HSG in 27 of 33 patients. Bilateral tubal occlusion was diagnosed in one of the remaining six patients and was confirmed by laparoscopy. Successful selective tubal catheterization was performed in one additional patient with unilateral and one patient with bilateral fallopian tube occlusion. In three cases, the catheter became dislocated at the end of the examination without demonstration of tubal patency. Since all three patients refused diagnostic laparoscopy and conventional HSG, possible bilateral occlusions of the fallopian tubes could not be

    To investigate whether preclinical laparoscopy training offers a benefit over standard apprenticeship training and apprenticeship training in combination with simulation training. This randomized controlled trial consisted of 3 groups of first-year surgical registrars receiving a different teaching method in laparoscopic surgery. The KU LEUVEN Faculty of Medicine is the largest medical faculty in Belgium. Thirty final-year medical students starting a general surgical career in the next academic year. Thirty final-year medical students were randomized into 3 groups, which differed in the way they were exposed to laparoscopic simulation training but were comparable in regard to ambidexterity, sex, age, and laparoscopic psychomotoric skills. The control group received only clinical training during surgical residentship, whereas the interval group received clinical training in combination with simulation training. The registrars were allowed to do deliberate practice. The Centre for Surgical Technologies Preclinical Training Programme (CST PTP) group received a preclinical simulation course during the final year as medical students, but was not exposed to any extra simulation training during surgical residentship. At the beginning of surgical residentship and 6 months later, all subjects performed a standardized suturing task and a laparoscopic cholecystectomy in a POP Trainer. All procedures were recorded together with time and motion tracking parameters. All videos were scored by a blinded observer using global rating scales. At baseline the 3 groups were comparable. At 6 months, for suturing, the CST PTP group was better than both the other groups with respect to time, checklist, and amount of movements. The interval group was better than the control group on only the time and checklist score. For the cholecystectomy evaluation, there was a statistical difference between the CST PTP study group and both other groups on all evaluation scales in favor of the CST PTP

    Laparoscopy is a revolutionary technique in modern surgery. However, the comparative efficacy between two-dimensional laparoscopy and three-dimensional laparoscopy remains in uncertainty. Therefore we performed this systematic review and meta-analysis in order to seek for answers. Databases of PubMed, Web of Science, EMBASE and Cochrane Library were carefully screened. Clinical trials comparing two-dimensional versus three-dimensional laparoscopy were included for pooled analysis. Observational and randomized trials were methodologically appraised by Newcastle-Ottawa Scale and Revised Jadad's Scale respectively. Subgroup analyses were additionally conducted to clarify the potential confounding elements. Outcome stability was examined by sensitivity analysis, and publication bias was analyzed by Begg's test and Egger's test. 21 trials were screened out from the preliminary 3126 records. All included studies were high-quality in methodology, except for Bilgen 2013 and Ruan 2015. Three-dimensional laparoscopy was superior to two-dimensional laparoscopy in terms of surgical time (P analysis. Although Begg's test (P = 0.215) and Egger's test (P = 0.003) revealed that there was publication bias across included studies, Trim-and-Fill method confirmed that the results remained stable. Three-dimensional laparoscopy is a preferably surgical option against two-dimensional laparoscopy due to its better surgical efficacy.

    To compare the outcome of robotic-assisted laparoscopy vs conventional laparoscopy in the management of ovarian masses. Retrospective cohort (Canadian Task Force classification II-3). Academic medical centre in the northeast United States. Retrospective medical record review of 71 consecutive patients with presumed benign ovarian masses. Robotic-assisted laparoscopy in 30 patients with presumed benign ovarian masses was compared with conventional laparoscopy in 41 patients. Operative outcomes including operative time, estimated blood loss, length of hospital stay, and complications were recorded. Standard statistical analysis was used to compare the outcomes in the 2 groups. Mean (SD) operative time in the robotic group was 1.95 (0.63) hours, which was significantly longer than in the conventional laparoscopic group, 1.28 (0.83) hours (p = .04). Estimated blood loss in the robotic group was 74.52 (56.23) mL, which was not significantly different from that in the conventional laparoscopic group, 55.97 (49.18) mL. There were no significant differences in length of hospital stay between the robotic and conventional laparoscopic groups: 1.20 (0.78) days and 1.48 (0.63). Conversion to laparotomy was not necessary in either group of patients. Intraoperative and postoperative complications were similar between the 2 groups. Robotic-assisted laparoscopy is a safe and efficient technique for management of various types of ovarian masses. However, conventional laparoscopy is preferred for management of ovarian masses because of shorter operative time. Prospective studies are needed to evaluate the outcomes of robotic-assisted laparoscopic management of benign and malignant ovarian neoplasms. Copyright © 2014 AAGL. Published by Elsevier Inc.

    To determine whether the proportion of several leukocyte subsets is modulated in the endometrium of patients with endometriosis and, if yes, whether it can be used for diagnostic purposes. Case-control study. Eight clinical institutions of the Montreal area. Women who underwent laparoscopy or laparotomy between 1997 and 2001, who had regular menstrual cycles and were not under hormone treatment for the previous 3 months were selected. This study included 368 women, 173 with surgically confirmed endometriosis and 195 controls with no surgical evidence of endometriosis. Cytometry analysis was used to measure the proportion of several leukocyte subsets among CD45(+) endometrial cells. The proportion of CD3(+), CD16(+), CD3(-)HLADR(-), CD3(-)CD45RA(-), CD3(+)CD16(-), CD3(+)CD56(-), CD56(-)CD16(+), and CD16b(+) leukocytes was significantly altered in the endometrium of cases compared with controls. A multiple logistic regression model was adjusted with these endometrial leukocytes, serum CA-125 levels, risk factors, and confounders. The diagnostic performance of this predictive model was defined by a specificity of 95% and a sensitivity of 61%. Furthermore, the positive and negative predictive values were 91% and 75%, respectively. This predictive model represents a novel diagnostic tool to identify women with a high likelihood of suffering from endometriosis.

    Complications associated with initial abdominal entry are a prime concern for laparoscopic surgeons. In order to minimize first access-related complications in laparoscopy, several techniques and technologies have been introduced in the past years. This investigation compares two laparoscopic access techniques. 194 women underwent laparoscopic surgery for simple ovarian cysts: 93 were assigned to direct optical access (DOA) abdominal entry (group I), and 101 women to classical closed method by Verres needle, pneumoperitoneum and trocar entry (group II). The following parameters were compared: time required for entry into abdomen, occurrence of vascular and/or bowel injury, blood loss. The results were analyzed using SAS software. p-valueVerres methods, commonly used by gynecologists, suggests that the visual entry system confers a statistical advantage over closed entry technique with Verres needle, in terms of time saving and due to the minor vascular and bowel injuries, thus enabling a safe and expeditious, visually-guided, entry for surgeons. 2009 Elsevier Ireland Ltd.

    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.

  13. Task performance in standard laparoscopy in comparison with single-incision laparoscopy in a modified skills trainer.

    Wright, Andrew S; Khandelwal, Saurabh

    2016-08-01

    Single-incision laparoscopy (SIL) is similar to conventional laparoscopic surgery (LAP), but carries specific technical challenges due to lack of triangulation, reduced dexterity, conflicts due to inline instrumentation, and impaired visualization. This study was designed to evaluate technical skill performance of SIL versus LAP surgery in a simulated environment. We developed a modified laparoscopic skills trainer for SIL based upon the fundamentals of laparoscopic surgery (FLS) model. This includes a standard laparoscopic tower for visualization, allowing replication of the conflicts between scope and instruments. It also has a modified trainer box allowing use of different access devices and instruments for SIL. Sixteen subjects at different levels of training (novice through expert) completed four FLS tasks with standard LAP techniques. They then practiced the same tasks using SIL technique until they reached a steady state of performance. The first and last SIL trials were recorded. Baseline SIL peg transfer was worse than FLS (254 ± 157 s vs 99 ± 27, p < 0.0002). Final SIL time was still significantly worse than FLS (173 ± 130, p < 0.02). FLS, baseline SIL, and final SIL circle cutting were not significantly different (p = 0.058). Final SIL loop ligation was significantly faster than FLS (48 ± 19 vs 70 ± 42, p < 0.05). FLS suturing was faster than SIL suturing (281 ± 188 vs. 526 ± 105, p < 0.01). There was substantial dropout due to frustration with SIL, and only two surgeons were able to successfully complete SIL suturing. There are technical challenges with SIL that vary depending on task. Peg transfer and suturing were significantly impaired in SIL, while circle cutting was not significantly affected, and ligating loop was faster with SIL than LAP. These challenges may impact clinical outcomes of SIL and should influence training in SIL as well as future product development.

    What is the diagnostic accuracy of 2D/3D hysterosalpingo-foam sonography (HyFoSy) and 2D/3D-high-definition flow Doppler (HDF)-HyFoSy in comparison to laparoscopy with dye chromotubation (as the reference method) and 2D air/saline-enhanced hysterosalpingo-contrast sonography (HyCoSy) (as the initial index test)? 2D/3D-HDF-HyFoSy had the best diagnostic accuracy and was the only method that did not significantly differ from the reference method, while both 2D/3D-HyFoSy and 2D/3D-HDF-HyFoSy had significantly higher accuracy than 2D-air/saline-HyCoSy. Previous studies on X-ray hysterosalpingography and laparoscopy and dye as the reference standard have undermined the impact of older commercial contrast agents on the accuracy of ultrasound tubal patency tests. Recently, HyFoSy was reported to have very high accuracy in a small pilot study in comparison to laparoscopy and dye, and had a very high positive predictive value (PPV) for medical tubal occlusion. A new Doppler sonographic technique, known as HDF imaging with better axial resolution, fewer blooming artifacts and higher sensitivity than color and power Doppler imaging, has been introduced. A prospective observational study was performed on 132 women (259 Fallopian tubes) consecutively enrolled between 2013 and 2015. This study included infertile women of reproductive age who previously had not been examined for tubal patency and who presented for the evaluation to the university hospital, private hospital and clinic at which this study was conducted. 2D-Air/saline-HyCoSy, 2D/3D-HyFoSy and 2D/3D-HDF-HyFoSy and laparoscopy were performed independently by experienced readers. During HyFoSy, the 3D mode was used for standardization of pelvic scanning and observations of contrast flow without diagnosis after volume acquisition. Sensitivity, specificity, negative and positive predictive value (NPV and PPV), negative and positive-likelihood ratio (LR- and LR+) and 95% CI were calculated. McNemar's test and relative

    We performed a search of PUBMED and MEDLINE for articles concerning surgical management of early stage endometrial cancer from 1950 to 2011. From the articles collected we extracted data such as estimated blood loss, operating room time, complications, conversion to laparotomy, and length of hospital stay. Forty-seven relevant sources were analyzed. The patients in the laparoscopy group had less blood loss, fewer complications, longer operating room times, and a shorter length of stay. Lymph node count was similar in both groups. Although obesity is not a contraindication to laparoscopy, it does lead to a higher conversion rate. Route of surgical treatment had no impact on recurrence or survival. Robotic surgery has significant advantages over laparotomy, but advantages over laparoscopy are not as distinct. Laparoscopic hysterectomy offers several advantages over laparotomy. These advantages relate to improvements in patient care with comparable clinical outcome. After careful analysis we believe laparoscopy should be the standard of care for surgical management of early stage endometrial cancer. Copyright © 2012 AAGL. Published by Elsevier Inc.

    2014-01-01

    Background Although Brazilian National Public Health System (BNPHS) has presented advances regarding the treatment for obesity in the last years, there is a repressed demand for bariatric surgeries in the country. Despite favorable evidences to laparoscopy, the BNPHS only performs this procedure via laparotomy. Aim 1) Estimate whether bariatric surgeons would support the idea of incorporating laparoscopic surgery in the BNPHS; 2) If there would be an increase in the total number of surgeries performed; 3) As well as how BNPHS would redistribute both procedures. Methods A panel of bariatric surgeons was built. Two rounds to answer the structured Delphi questionnaire were performed. Results From the 45 bariatric surgeons recruited, 30 (66.7%) participated in the first round. For the second (the last) round, from the 30 surgeons who answered the first round, 22 (48.9%) answered the questionnaire. Considering the possibility that BNPHS incorporated laparoscopic surgery, 95% of surgeons were interested in performing it. Therefore, in case laparoscopic surgery was incorporated by the BNPHS there would be an average increase of 25% in the number of surgeries and they would be distributed as follows: 62.5% via laparoscopy and 37.5% via laparotomy. Conclusion 1) There was a preference by laparoscopy; 2) would increase the number of operations compared to the current model in which only the laparotomy is available to users of the public system; and 3) the distribution in relation to the type of procedure would be 62.5% and 37.5% for laparoscopy laparotomy.

    Recent studies reported the feasibility of intraoperative lymphatic mapping in women with endometrial cancer but none of these studies compared the sentinel lymph nodes (SLNs) detection rates obtainable through laparoscopy or laparotomy. The purpose of this study was to address this issue. Thirty-four patients with clinical stage I-II endometrial cancer were enrolled in this prospective comparative trial. Four milliliters of Patent Blue Violet were injected into the cervix after the induction of general anesthesia. The assessment of SLNs was done in 17 patients through laparoscopy and in 17 patients through laparotomy as first step of systematic pelvic lymphadenectomy. Both SLNs and non-SLNs were evaluated for micrometastases. The SLNs detection rate was significantly higher (82%) for laparoscopy than for laparotomy (41%; P = 0.008). Pelvic lymph node metastases were present in 6 out of 34 patients (18%) but only 3 (50%) of these patients were correctly identified. SLNs detection rate is significantly higher through laparoscopy than through laparotomy after vital dye pericervical injection but intraoperative vital dye pericervical injection is not reliable as part of standard care for predicting lymphatic spread in women with early stage endometrial cancer.

    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. To demonstrate the usefulness and advantages of the laparoscopic approach in the treatment of Dunbar syndrome. 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. 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. 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.

    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.

    Background: Leiomyomata is the most frequent gynecological neoplasm. One of the major complications of myomectomy is intrauterine adhesion (synechiae). Objective: To evaluate and compare the rate and severity of synechiae formation after myomectomy by laparotomy and laparoscopy. Materials and Methods: In this non-randomized interventional trial, hysteroscopy was performed in all married fertile women who had undergone myomectomy (type 3-6 interamural and subserosal fibroids) via laparotomy and laparoscopy in Tehran’s Arash Hospital from 2010 to 2013. Three months after the operation, the occurrence rate and severity of intrauterine synechiae, and its relationship with type, number and location of myomas were investigated and compared in both groups. Results: Forty patients (19 laparoscopy and 21 laparotomy cases) were studied. Both groups were similar regarding the size, type (subserosal or intramural), number and location of myoma. The occurrence rate of synechiae in the laparoscopy and laparotomy group was 21% and 19%, respectively; showing no significant difference (p=0.99). Among all patients, no significant relationship was found between the endometrial opening (p=0.92), location (p=0.14) and type of myoma (p=0.08) with the occurrence rate of synechiae. However, a significant relationship was observed between myoma’s size (p=0.01) and the location of the largest myoma with the occurrence of synechiae (p=0.02). Conclusion: With favorable suturing methods, the outcome of intrauterine synechiae formation after myomectomy, either performed by laparotomy or laparoscopy, is similar. In all cases of myomectomy in reproductive-aged women, postoperative hysteroscopy is highly recommended to better screen intrauterine synechiae. PMID:26000007

    To compare the proficiency and preference of physicians in performing standard tasks in a box trainer using 2-dimensional (2D) versus 3-dimensional (3D) laparoscopy. Prospective randomized controlled trial. Prospective, randomized controlled trial (Canadian Task Force classification I). Tertiary care teaching hospital. Thirty physicians from the Department of Obstetrics and Gynecology. Participants were randomly assigned to perform a set of 3 to 4 tasks in a pelvic trainer using 2D laparoscopy first and then 3D laparoscopy, and vice versa. The time taken to complete the tasks and side effects experienced were noted. Participants were asked to complete a modified Global Operative Assessment of Laparoscopic Skills (GOALS) form at the end of their tasks to evaluate their experiences and to assess their own proficiency with both visual modalities. The time taken for peg transfer, duct cannulation, and suturing was significantly faster using 3D laparoscopy compared with 2D laparoscopy. There were no significant differences in the time taken for pattern cutting with both visual modalities. Participants experienced more dizziness using 3D laparoscopy (6.9% vs 37.9%; p = .004). The GOALS self-evaluation score was significantly higher for 3D compared with 2D laparoscopy. After the study, 11 of 29 (37.9%) participants preferred 2D, 16 of 29 (55.2%) preferred 3D, and 1 of 29 (8.3%) had no preference. Although 3D laparoscopy scored higher on self-evaluation and was preferred by more participants, it only gave better objective performance in the completion of some selected tasks by participants with intermediate skill levels and was associated with more dizziness. Further studies are needed to determine the value of 3D laparoscopy, especially when used in the clinical setting. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

    Intestinal malrotations with midgut volvulus are surgical emergencies that can lead to life-threatening intestinal necrosis. This study evaluates the feasibility and the outcomes of laparoscopic treatment of midgut volvulus compared with classic open Ladd's procedure in neonates. The medical records of all neonates with diagnosis of malrotation and volvulus, who underwent surgery between January 1993 and January 2014, were reviewed. We considered the group of neonates laparoscopically treated (Group A, n = 20) and we compared it with an equal number of neonates treated with the classical open Ladd's procedure (Group B, n = 20). The median age at surgery was 8.4 days and the mean weight was 3.340 kg. The suspicion of volvulus was documented by plain abdominal radiograph, upper gastrointestinal contrast study, and/or ultrasound scanning of the mesenteric vessels. All the patients were treated according to the Ladd's procedure. Conversion to an open procedure was necessary in 25% of the patients. The mean operative time was 80 minutes (28-190 minutes) in Group A and 61 minutes (40-130 minutes) in Group B (P = .04). The median time to full diet (P = .02) and hospital stay (P = .04) was better in Group A. Rehospitalization because of recurrence of occlusive symptoms occurred in 30% of patients in Group A (n = 6) and in 40% of patients in Group B (n = 8). Among these, all the 6 patients of Group A underwent redo surgery for additional division of Ladd's bands or debridement; instead in Group B, 4 of 8 patients underwent open redo surgery. Laparoscopic exploration is the procedure of choice in case of suspicion of intestinal malrotation and volvulus. Laparoscopic treatment is feasible and safe even in neonatal age without additional risks compared with classical open Ladd's procedure.

    Full Text Available Aim: We aimed at analysing the patients, who underwent surgical treatment in our hospital after having abdominal wounding by firearm in the war at Syria, retrospectively. Material and Method: The files of Syrian patients, who applied to Emergency Service of Harran University Medical Faculty because of gunshot wounds and had operation after being hospitalized in General Surgery Clinic due to abdominal injuries between the years of 2011 and 2014, were analysed retrospectively. Results: 175 Syrian patients, who had abdominal injuries by firearms, underwent operation in our general surgery clinic. 99.4% (n=174 of the patients were male, and 0.6% (n=1 were female. Trauma-admission to hospital times of all cases were %u2265 6 hours. 62.8% (n=110 of the patients had isolated abdominal injuries, and 37.1% (n=65 had two or more system injuries. The frequency of more than one organ injuries in abdominal region was 44.5% (n=78 and the most frequent complication was wound infection (10%. Negative laparoscopy was 2.8% (n=5, support for intensive care was 38.2% (n=67, average duration of intensive care unit stay was 5.57 days and mortality was 9.7% (n=17. Discussion: In our study, it was seen that infectious morbidity and mortality increased for the patients, who applied to our hospital because of abdominal injuries by firearm, particularly the ones with gastrointestinal perforation, if trauma-admission to hospital times were %u2265 6 hours. And this shows us that the early intervention to injuries that perforate gastrointestinal tract was an important factor for decreasing morbidity and mortality.

    This is an updated version of the original review, published in Issue 1, 2011, of The Cochrane Library. Acute lower abdominal pain is common, and making a diagnosis is particularly challenging in premenopausal women, as ovulation and menstruation symptoms overlap with symptoms of appendicitis, early pregnancy complications and pelvic infection. A management strategy involving early laparoscopy could potentially provide a more accurate diagnosis, earlier treatment and reduced risk of complications. To evaluate the effectiveness and harms of laparoscopy for the management of acute lower abdominal pain in women of childbearing age. The Menstrual Disorders and Subfertility Group (MDSG) Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, LILACS and CINAHL were searched (October 2013). The International Clinical Trials Registry Platform (ICTRP) was also searched. No new studies were included in this updated version. Randomised controlled trials (RCTs) that included women of childbearing age who presented with acute lower abdominal pain, non-specific lower abdominal pain or suspected appendicitis were included. Trials were included if they evaluated laparoscopy with open appendicectomy, or laparoscopy with a wait and see strategy. Study selection was carried out by two review authors independently. Data from studies that met the inclusion criteria were independently extracted by two review authors and the risk of bias assessed. We used standard methodological procedures as expected by The Cochrane Collaboration. A summary of findings table was prepared using GRADE criteria. A total of 12 studies including 1020 participants were incorporated into the review. These studies had low to moderate risk of bias, mainly because allocation concealment or methods of sequence generation were not adequately reported. In addition, it was not clear whether follow-up was similar for the treatment groups

    The experiences of special X-ray diagnostics of female genitals are described, that were made in 41 children within a period of 12 years. The superiority of the X-ray-technique arises from the impossibility of the manual examination in newborn and infants and the avoidance of diagnostic techniques like laparoscopy or laparotomy. All the examination techniques are described. In intersexualmarked patients the discrimination into six types after Shopfner is preferred. Malformations and tumours are dealt with briefly. The relations between skeleton and female genitals are pointed out at the example of the gonadal dysgenesis. (orig.) [de

    Full Text Available Adenomyosis or endometriosis genitalis interna is a frequent benign disease of women in fertile age. It causes symptoms like bleeding disorders and dysmenorrhea and seems to have a negative effect on fertility. Adenomyosis can be part of a complex genital and extragenital endometriosis but also can be found as a solitary uterine disease. While peritoneal endometriosis can be easily diagnosed by laparoscopy with subsequent biopsy, the determination of adenomyosis is difficult. In the following literature review, the diagnostic methods clinical history and symptoms, gynecological examination, 2D and 3D transvaginal ultrasound, MRI, hysteroscopy, and laparoscopy will be discussed step by step in order to evaluate their predictive value in the diagnosis of adenomyosis.

    laparoscopia revelou obstrução bilateral. Em 15 casos (65,2% em que a HSG havia demonstrado obstrução bilateral, a laparoscopia foi normal ou revelou apenas obstrução unilateral. CONCLUSÕES: a laparoscopia demonstrou sua relevância diagnóstica e terapêutica revelando-se fundamental na clarificação do status tubo-peritoneal. Permitiu a realização concomitante de atos terapêuticos, possibilitando a definição da melhor estratégia terapêutica no casal infértil.PURPOSE: to evaluate the contribution of diagnostic laparoscopy to approach the infertile couple. METHODS: retrospective analysis of 86 consecutive cases of patients who were accompanied in the infertility appointments and were submitted to diagnostic laparoscopy from January 2004 to December 2006. Eighty-two of these patients had been submitted to hysterosalpingography (HSG prior to laparoscopy. The laparoscopic findings were analyzed, as well as the accessory procedures, and the results of the hysterosalpingography and of the laparoscopy were correlated. Statistical analysis was performed by the use of the Statistical Package for the Social Sciences 15. The sensitivity and the specificity of HSG were determined and the confidence intervals were calculated with an alpha error of 0.05 (95%CI. RESULTS: the laparoscopy revealed 21 cases of endometriosis (24.4%, 14 cases of uni/bilateral inflammatory disease of the salpinx (16.3%, and 16 cases of pelvic inflammatory disease (18.6%. Adhesiolysis and ablation of endometrial lesions were performed in eight patients. There were also other accessory procedures: two salpingostomies, two paraovarian cystectomies, two ovarian cystectomies and three ovarian drillings. The tubal patency test during laparoscopy was normal in 44 cases (53%, revealed unilateral obstruction in 21 cases (25.3% and bilateral obstruction in 17 cases (20.5%. The results of the hysterosalpingography were similar to those of the laparoscopy in 44 out of the 82 cases (53.7%. HSG sensitivity was

    Appendicitis in pregnancy (AIP) is the most common nonobstetric cause of an acute abdomen requiring surgical intervention. Diagnostic difficulties arising from gestational symptoms compound the risk of foetal loss after negative appendicectomy and exponentially increase the risk to mother and foetus with delay in genuine cases. In this article, we investigate the symptoms and signs of AIP and attempt to identify consistent clinical features and review the role of imaging in diagnosis. MEDLINE and PubMed were searched for case-control studies recording preoperative symptoms/signs suggestive of AIP, as well as appendiceal pathology. Combined likelihood and odds ratios (OR) were created for clinical features across homogenous papers. Papers examining the use of laparoscopy, ultrasound (US), computerized tomography (CT) and magnetic resonance imaging (MRI) were assessed qualitatively. Seven papers met the inclusion criteria for the analysis of consistent clinical features (450 patients). The only symptoms or signs significantly associated with a diagnosis of appendicitis were nausea (OR: 2.21, 95%CI: 1.34-3.66), vomiting (OR: 0.82-15.6 range) and peritonism (OR: 1.80, 95%CI: 1.06-3.04). US, CT and MRI have all been used to successfully diagnose AIP. Laparoscopic appendicectomy has been safely undertaken in pregnancy. Appendicitis will continue to challenge the diagnostic acumen of surgeons. Whilst useful, consensus regarding the safety of laparoscopy, CT and MRI in pregnancy is yet to be achieved.

    The use of mini-laparoscopy scissors to remove a central venous catheter inadvertently fixed to the wall of the brachiocephalic vein is described. During a rethoracotomy in a 15-year-old female patient, a central venous catheter preoperatively introduced in the left subclavian vein was inadvertently trapped by a suture and fixed to the wall of the left brachiocephalic vein. The foreign body was removed by use of a transjugularly introduced venous sheath, a catheter wire snare, and mini-laparoscopy scissors. The fixed catheter was freed from the wall of the vein under fluoroscopic control with the help of a mini-laparoscopy scissors. Since the intravasal end of the catheter had already been grasped during mobilization with the wire snare it could be completely removed subsequently without any problem. The percutaneous, intravascular use of mini-laparoscopy instruments may be considered for foreign body removal in special cases.

We also evaluated short-term and oncologic outcomes after laparoscopy and open surgery.Methods: A total of 100 consecutive stage IV patients undergoing open (n=61 or laparoscopic (n=39 major resection were analyzed. There were four cases (10% of conversion to laparotomy in the laparoscopy group.Results: Pathological T4 tumors (56% vs 26%, primary colon cancers (74% vs 51%, and larger tumor diameter (6 vs 5 cm were more commonly managed with open surgery. Right colectomy was more common in the open surgery group (39% and low anterior resection was more common in the laparoscopy group (39%, P=0.002. Hepatic metastases in segments II, III, IVb, V, and VI were more frequently resected with laparoscopy (100% than with open surgery (56%, although the difference was not statistically significant. In colon and rectal cancers, mean operative time and 30-day complication rates of laparoscopy and open surgery did not differ. In both cancers, mean time to soft diet and length of hospital stay were shorter in the laparoscopy group. Mean time from surgery to chemotherapy commencement was significantly shorter with laparoscopy than with open surgery. In colon and rectal cancers, 2-year cancer-specific and progression-free survival rates were similar between the laparoscopy and open surgery groups.Conclusion: Based on our findings, laparoscopy can be selected as an initial approach in patients with a primary tumor without adjacent organ invasion and patients without primary tumor-related symptoms.

    Elderly patients usually have concurrent ailments, and the safety and effectiveness of laparoscopy-assisted distal gastrectomy (LADG) for these patients have been controversial. This study aimed to evaluate whether laparoscopy-assisted distal gastrectomy is safe and effective for elderly patients aged 80 years and over, as well as to clarify their long-term prognosis. A total of 31 patients aged 80 years and over who underwent LADG in our hospital were retrospectively reviewed. Peri- and postoperative data were compared with those of 38 patients aged 65 years and younger. The median follow-up period of the elderly and younger group was 56.0 and 63.0 months, respectively, and their prognosis was examined. There were significant differences between the two groups in preoperative respiratory and renal functions, hemoglobin, and nutritional index. Significant differences in postoperative complications were seen only in pneumonia and delirium. There were no hospital deaths, but the 3-year and 5-year overall survival rates were significantly lower in the elderly group than in the non-elderly group. However, in the elderly group, only one patient died of gastric cancer recurrence, whereas four died of cardiovascular disease and three died of pneumonia during follow-up. Therefore, the recurrence-free survival rate was not significantly different between the groups. LADG seems to be safe and effective even for elderly patients, and their prognosis was satisfactory. However, careful monitoring for cardiovascular and pulmonary disease should be observed during the follow-up period.

    To describe the clinical workup and laparoscopic treatment of ovarian remnant syndrome in dogs and cats. After confirming the diagnosis with some or all of the following tests - vaginoscopy with cytology, hormonal tests, and ultrasound - laparoscopic removal of the ovarian remnants was performed. A three-portal technique was used in the four dogs and a two-portal technique in the two cats. All patients recovered well and were discharged the same day. No post-operative complications occurred in any patient. Overall, in the hands of an experienced laparoscopic surgeon, laparoscopic removal of ovarian remnants appears to be a safe procedure in dogs and cats. In addition, laparoscopy offers the advantages of excellent visualization and a reduced morbidity for the patient. Careful case selection and complete pre-operative workup to rule out co-morbidities or underlying neoplasia are important. As with any laparoscopy the surgeon should always be prepared to convert to an open laparotomy if necessary.

    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.

    Several surgical specialties use laparoscopy and share many of the same techniques and challenges, such as entry approaches, equipment, and complications. However, most basic training programs focus on a single specialty. The objective of this study was to describe the implementation of a regional cross-specialty training program for basic laparoscopy, to increase the flexibility of educational courses, and to provide a more efficient use of simulation equipment. Using a regional training program in basic laparoscopy for gynecology as a model, we developed a cross-specialty training program for residents in surgery, gynecology, urology, and thoracic surgery. We reviewed data on training for the first year of the program and evaluated the program by using a scoring system for quality criteria for laparoscopic curricula and skills. We held 6 full-day theoretical courses involving 67 residents between September 1, 2013, and August 31, 2014. In the weeks following each course, residents practiced in a self-directed, distributed, and proficiency-based manner at a simulation center and in local hospital departments. A total of 57 residents completed the self-practice and a subsequent practical animal laboratory-based course. The structure of the training program was evaluated according to identified quality criteria for a skills laboratory, and the program scored 38 of a maximum 62 points. Implementation of a regional cross-specialty training program in basic laparoscopy is feasible. There are several logistic benefits of using a cross-specialty approach; however, it is important that local departments include specialty-specific components, together with clinical departmental follow-up.

    To compare transumbilical laparoendoscopic single-site surgery with conventional laparoscopy for the resection of retroperitoneal paragangliomas. In the present case-control study, we compared 11 transumbilical laparoendoscopic single-site surgery procedures with 22 conventional laparoscopy procedures carried out to treat retroperitoneal paragangliomas between June 2004 and October 2013 at Peking Union Medical Hospital, Beijing, China. Operative time, estimated intraoperative blood loss, blood transfusions, intraoperative hypertension, intraoperative hypotension, highest intraoperative systolic blood pressure, lowest intraoperative systolic blood pressure, postoperative fatigue time, postoperative systematic inflammation reaction syndrome, 24-h postoperative visual analog scale scores, postoperative hospital stay duration, and postoperative complications were recorded and analyzed. There were no significant differences in patient characteristics. All surgical procedures were successfully completed in both groups. Minor complications occurred in one case in the laparoendoscopic single-site surgery group and in two cases in the conventional laparoscopy group. In the laparoendoscopic single-site surgery group, the operative time was longer than that in the conventional laparoscopy group (P = 0.001). There were no significant differences in terms of intraoperative hypertension, intraoperative hypotension, highest intraoperative systolic blood pressure, lowest intraoperative systolic blood pressure, estimated blood loss, postoperative fatigue time, postoperative hospital stay or systematic inflammation reaction syndrome between the two groups. The 24-h postoperative visual analog scale score was lower in the laparoendoscopic single-site surgery group (P = 0.002). No recurrence or metastases were observed over the duration of the postoperative follow up. In properly selected patients, transumbilical laparoendoscopic single-site surgery is a feasible, safe and effective

    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.

    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.

    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.

    Simulated laparoscopy training is limited by its low-quality image. A high-definition (HD) laparoscopic training box was developed under the present necessity of simulating advanced surgery. To describe and test a new HD laparoscopic training box for advanced simulation training. We describe the features and image quality of the new training box. The simulator was tested and then evaluated by a group of 76 expert surgeons using a 4-item questionnaire. To assess the effectiveness of training using this simulation box, 15 general surgery residents were trained to perform a laparoscopic jejuno-jejunostomy in a validated simulation program. They were assessed with objective rating scales before and after the training program, and their results were compared with that of experts. The training box was assembled using high-density fiberglass shaped as an insufflated abdomen. It has an adapted full-HD camera with a LED-based illumination system. A manually self-regulated monopod attached to the camera enables training without assistance. Of the expert surgeons who answered the questionnaire, 91% said that the simulation box had a high-quality image and that it was very similar to real laparoscopy. All residents trained improved their rating scores significantly when comparing their initial versus final assessment ( P .2). This novel laparoscopic training box presents a high-resolution image and allows training different types of advanced laparoscopic procedures. The simulator box was positively assessed by experts and demonstrated to be effective for laparoscopy training in resident surgeons.

    One by one, minimally invasive alternatives to established gastrointestinal procedures have become clinical routine. We have studied the use of laparoscopy in four common procedures-cholecystectomy, appendectomy, reflux surgery, and bariatric surgery-as well as in major resectional gastrointestinal surgery in Sweden. The National Patient Registry was used to identify all in-hospital procedures performed in patients above the age of 15 during 1998-2014, meeting our inclusion criteria. For each group, the annual number of procedures and proportion of laparoscopic surgery were studied, as well as applicable subgroups. Differences in age, gender, as well as geographical differences were evaluated in the most recent 3-year period (2012-2014). In total, 537,817 procedures were studied, 43% by laparoscopic approach. In 2012-2014, the proportion of laparoscopic surgery ranged from high rates in the four common procedures (cholecystectomy 81%, appendectomy 47%, reflux surgery 72%, and bariatric surgery 97%) to rather low numbers in resectional surgery (4%-10%), however, increasing in the last years. In appendectomy and cholecystectomy, men were less likely to have laparoscopic surgery (42% versus 51% and 74% versus 85%, respectively, p laparoscopy were also noted, for example, the proportion of laparoscopic appendectomy varied from 11% to 76% among the 21 different Swedish counties. The proportion of laparoscopy was high in the four common procedures and low, but rising, in major resectional surgery. A large variation in the proportion of laparoscopic surgery by age, gender, and place of residence was noted.

    Laparoscopy surgery has been widely used for many decades and combined laparoscopic procedures have become favorable choices for concomitant pathologies in the abdomen. However, the type of combination procedures and their safety in obese women have not been well elucidated in obese women. Here we retrospectively reported 147 obese women underwent combined laparoscopic gynecological surgery and cholecystectomy/appendicectomy in our hospital from January 2003 to December 2011. Of the total number of patients (n = 147), various laparoscopic gynecological surgeries were combined with laparoscopic cholecystectomy in 93 patients, and were combined with laparoscopic appendectomy in the rest 54 patients. Patients' ages ranged from 24 to 55 years with an average of 33 years. Our results showed that combined procedures caused various operative time and blood loss, with no difference considering the time to resume oral intake and length of hospital stay. Intraoperative complications occurred in a total of 7 patients (4.8%). None of the patients suffered from major complications after laparoscopic surgery, and minor postoperative complications occurred in 30 patients (20.4%). The follow-up period ranged from 6 to 24 months (average, 18.5 months). None of the patients developed complications during follow-up, except that one patient suffered from colporrhagia. Our results further suggest that the combined abdominal laparoscopic procedures of gynecologic and general surgery are safe and economic choices for obese women, and benefit patients in many ways including lesser pain, shorter hospital stays and earlier recovery.

    To describe disease course, histopathology, and outcomes for infants with atypical presentations of alveolar capillary dysplasia with misalignment of the pulmonary veins (ACDMPV) who underwent bilateral lung transplantation. We reviewed clinical history, diagnostic studies, explant histology, genetic sequence results, and post-transplant course for 6 infants with atypical ACDMPV who underwent bilateral lung transplantation at St. Louis Children's Hospital. We compared their histology with infants with classic ACDMPV and compared their outcomes with infants transplanted for other indications. In contrast with neonates with classic ACDPMV who present with severe hypoxemia and refractory pulmonary hypertension within hours of birth, none of the infants with atypical ACDMPV presented with progressive neonatal respiratory failure. Three infants had mild neonatal respiratory distress and received nasal cannula oxygen. Three other infants had no respiratory symptoms at birth and presented with hypoxemia and pulmonary hypertension at 2-3 months of age. Bilateral lung transplantation was performed at 4-20 months of age. Unlike in classic ACDMPV, histopathologic findings were not distributed uniformly and were not diffuse. Three subjects had apparent nonmosaic genetic defects involving FOXF1. Two infants had extrapulmonary anomalies (posterior urethral valves, inguinal hernia). Three transplanted children are alive at 5-16 years of age, similar to outcomes for infants transplanted for other indications. Lung explants from infants with atypical ACDMPV demonstrated diagnostic but nonuniform histopathologic findings. The 1- and 5-year survival rates for infants with atypical ACDMPV are similar to infants transplanted for other indications. Given the clinical and histopathologic spectra, ACDMPV should be considered in infants with hypoxemia and pulmonary hypertension, even beyond the newborn period. Copyright © 2017 Elsevier Inc.

    To present a case of hydronephrosis and hydroureter secondary to pelvic endometriosis and to discuss the pitfalls in laparoscopic management. A 37-year-old nulligravida woman had mild elevation of blood pressure for about 1 year without abdominal pain, dyspareunia, or dysmenorrhea. Renal ultrasound revealed left hydronephrosis and a 4-cm pelvic cyst. Intravenous pyelogram showed distal ureteral obstruction. An MRI with fat saturation disclosed a left ovarian endometrioma and a lesion in the uterosacral ligament causing periureteral compression. Laparoscopic findings included a dilated left ureter above the uterosacral ligament, left uterosacral ligament endometriosis with adhesions, and a 4-cm left ovarian endometrioma. Cystoureteroscopy showed external ureteral compression 2 cm above the ureteral orifice. A ureteral catheter was placed. The left endometrioma was enucleated and ureterolysis was performed. The latter procedure had to be discontinued because of bleeding from descending uterine vessels. The ureteral catheter was removed 2 months later and her blood pressure gradually returned to normal. However, after 1 year, she was found to have recurrent hydronephrosis and underwent segmental resection of the distal ureter and reconstruction by end-to-end reanastomosis. In women of reproductive age, hydronephrosis and hypertension may be the only symptoms of endometriosis. While laparoscopic treatment is useful in endometriosis, it may fail in the presence of chronic inflammation and severe fibrosis.

    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.

    Despite diffusion of laparoscopic hepatectomy, the acquisition of necessary skills is not easy for open liver surgeons. Concepts and techniques have totally changed in laparoscopic hepatectomy compared with open hepatectomy, which is an underlying cause of a technical hurdle in laparoscopic hepatectomy. This study aimed to illustrate laparoscopy-specific concepts and techniques for hepatectomy. Video footages of laparoscopic and open hepatectomies stored in the Institut Mutualiste Montsouris and Kyoto University were reviewed to define the differences in surgical view, surgical concept, and technical details, using left lateral sectionectomy (LLS) and right hepatectomy (RH) as representative examples. By comparison with open LLS and RH, laparoscopy-specific procedures were identified with regard to surgical view, parenchymal transection, available landmarks, and vascular dissection. By laparoscopy, the surgical field was constantly viewed and accessed from the caudal side to the cranial side. Similarly, the parenchyma was divided, and intrahepatic vessels were dissected in the same direction. Laparoscopy-specific landmarks were identified for both LLS and RH, behind the liver. The concepts and techniques in laparoscopic hepatectomy are totally different from those of open hepatectomy because of the different surgical views. Understanding the laparoscopy-specific concepts and techniques would facilitate safe and efficient execution of laparoscopic hepatectomy.

    Carry out a preliminary study comparing postoperative pain and intraoperative and postoperative complications between micro-laparoscopy and laparoscopic monotrocart non-oncological adnexal surgery. All patients should benefit from a benign adnexal surgery were included prospectively from February to May 2014. The insufflation pressure, infiltration of trocar holes with a local anesthetic, postoperative analgesics were prescribed standardized. Operative and postoperative complications, type and length of hospital stay as well as EVA and analgesic consumption were recorded. Nine patients were included in monotrocart group versus 7 in the micro-laparoscopy group. There were no differences in operative and postoperative complications, the type and length of hospital stay, as well as cosmetics satisfaction. However, there was a significant difference in the VAS to D2 (2.15 vs. 4.08, P=0.04) and analgesic consumption at D0 (P=0.04), D1 (P=0.04), D2 (P=0.02) and D3 (P=0.01), for the benefit of micro-laparoscopy. Despite an enrollment of patients low, micro-laparoscopy appears to have a significant advantage over the monotrocart laparoscopy for postoperative pain in benign adnexal surgery.

    Background/Aims Laparoscopy is important in staging pancreatic cancer, but false negatives remain problematic. Making tumors fluorescent has the potential to improve the accuracy of staging laparoscopy. Methodology Orthotopic and carcinomatosis models of pancreatic cancer were established with BxPC-3 human pancreatic cancer cells in nude mice. Alexa488-anti-CEA conjugates were injected via tail vein 24 hours prior to laparoscopy. Mice were examined under bright field laparoscopic (BL) and fluorescence laparoscopic (FL) modes. Outcomes measured included time to identification of primary tumor for the orthotopic model and number of metastases identified within 2 minutes for the carcinomatosis model. Results FL enabled more rapid and accurate identification and localization of primary tumors and metastases than BL. Using BL took statistically significantly longer time than FL. More metastatic lesions were detected and localized under FL compared to BL and with greater accuracy, with sensitivities of 96% vs. 40%, respectively, when compared to control. FL was sensitive enough to detect metastatic lesions laparoscopy with tumors labeled with fluorophore-conjugated anti-CEA antibody permits rapid detection and accurate localization of primary and metastatic pancreatic cancer in an orthotopic model. The results of the present report demonstrate the future clinical potential of fluorescence laparoscopy. PMID:22369743

    To investigate the surgical and oncological outcomes of hybrid laparoendoscopic single-site (LESS) in partial nephrectomy with reusable components compared with multiport laparoscopy. Hybrid LESS technique with auxiliary 3.5mm trocar (n=20) was compared with conventional multiport laparoscopy (n=26) by a prospective, paired, nonrandomized, and comparative study in partially nephrectomized patients. Follow-up average was 31±18.6 months. In one case, LESS was converted to laparoscopy. No differences were found regarding age, sex, body mass index, laterality, localization, tumor size or use of double J stent. Dominance of Loop-I (P=0.09) and benign histology (P=0.05) were observed in the LESS group. Neither there were differences regarding operating time, ischemia time, use of hemostatic materials, estimated blood loss, postoperative hemoglobin levels, transfusion or other complications. In any case, to extend the skin incision for specimen extraction was not necessary. Drainage time (P=0.006) and hospital stay (P=0.003) were better in LESS patients. Concerning complications, no significant differences were observed according Clavien-Dindo scale. In laparoscopic group one patient died of pulmonary embolism after hospital discharge. No positive margins were observed in any case. During follow-up neither tumor recurrence nor disease progression were observed. Regarding surgical outcomes, partial nephrectomy by LESS technique does not imply improvements, excepting shorter hospital stay, probably due to accurate surgical hemostasis and/or selection of cases. No surgical and oncological risks are involved, as well as no improvement in ischemia time, blood loss or transfusion rate. We find no significant difference in cosmetic outcomes.

    Diaphragmatic rupture is a serious but frequently missed condition that is potentially curable. While surgical management has classically been performed through open thoracotomy, a laparoscopic approach has been suggested as a preferable alternative. A man in his mid-50s presented with non-specific abdominal symptoms, 8 months after falling down some stairs. Diaphragmatic rupture was suspected after old rib fractures were noticed on an admitting chest radiograph. Further signs and symptoms presented following deterioration due to the unstable pathology. Prompt surgical treatment using laparoscopy was attempted with success and resulted in rapid and lasting improvement in symptoms.

The aim of this study was to investigate the correlation between pressure pain threshold (PPT of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT.Materials and methods: The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery. In group C, normal saline was infused at the corresponding time point. PPT assessment was performed 1 day before surgery and at postoperative 24 hours by using a pressure algometer at bilateral shoulder muscles (levator scapulae and supraspinatus and forearm (flexor carpi ulnaris. Meanwhile, bilateral shoulder pain was evaluated through visual analog scale score at 24 hours after surgery. Results: Preoperative PPT level of the shoulder, but not of the forearm, was significantly and negatively correlated with the intensity of ipsilateral PLSP. In group C, PPT levels of shoulder muscles, but not of forearm muscles, decreased after laparoscopy at postoperative 24 hours. The use of parecoxib significantly improved the decline of PPT levels of bilateral shoulder muscles (all P<0.01. Meanwhile, parecoxib reduced the incidence of PLSP (group P: 45% vs group C: 83.3%; odds ratio: 0.164; 95% confidence interval: 0.07–0.382; P<0

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    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.

    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.

    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.

    We report a unique case of intramucosal carcinoma in a tubulovillous adenoma arising from a single diverticulum. Endoscopic mucosal resection (EMR) was carried out successfully and completely with the assistance of laparoscopy. A 71-year-old man was admitted to our hospital because of melena and anemia. Emergent colonoscopy showed diverticulosis in the right-sided colon. However, endoscopy could not exactly detect the bleeding site. A flat elevated polyp was found within a single diverticulum located in the descending colon and diagnosed as an intramucosal carcinoma, as magnifying chromoendoscopy revealed a type IV pit pattern. As his diverticular bleeding repeated, a right-sided hemicolectomy was decided for treatment, the polyp within the diverticulum was also completely removed by EMR with the assistance of laparoscopy. Although a colonic perforation was detected immediately after EMR, the perforation was closed with endoclips intraluminally and also repaired laparoscopically from the serosal side. Histologically, the resected lesion was an intramucosal well-differentiated adenocarcinoma and the surgical margin was free of tumor. PMID:20333800

    The objective of this study was to evaluate laparoscopy training using pelvitrainers for gynaecological surgeons in a low-income country. The study was carried out in Madagascar from April 2016 to January 2017. The participants were gynaecological surgeons who had not previously performed laparoscopy. Each surgeon was timed to evaluate the execution times of four proposed exercises, based on the fundamentals of laparoscopic surgery (FLS) programme's skills manual, as follows: exercise 1, involving a simple object transfer; exercises 2 and 3, comprising complex object transfers; and exercise 4, a precision cutting exercise. The 8-month training and evaluation programme was divided into different stages, and the four following evaluations were compared: a pretest (T0), assessment at the end of the first training (T1) and auto-evaluation at 2 months (T2) and 8 months (T3). Eight participants were included. The median time was significantly reduced (Pincome countries before providing the necessary equipment. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    To assess complications and outcomes of pregnancies following laparoscopic abdominal surgery during the second and third trimesters of pregnancy. Retrospective single-center study of 23 cases of laparoscopic surgery in the second or third trimesters of pregnancy between January 2005 and May 2016. The laparoscopies were performed between 15 and 33 weeks of gestation, a mean of 23 weeks+2 days, with 6 cases in the 3rd trimester. The operations were: 11 cholecystectomies, 6 appendectomies, 1 intestinal occlusion (volvulus on a gastric band), 3 adnexal torsions, 1 ovarian cyst and 1 paratubal cyst with torsion. No secondary laparotomy was required. The postoperative courses were favorable in most cases. However, 3 appendectomies were complicated, one by chorioamnionitis and miscarriage at 20½ weeks of gestation and 2 by right iliac fossa abscesses requiring percutaneous radiological drainage, one of these women delivered a healthy term baby and the other had chorioamnionitis and preterm delivery at 34 weeks, followed by neonatal death. Laparoscopy can be safely performed for surgical indications in the second and third trimesters of pregnancy. In case of abdominal symptoms, a timely diagnosis is required to decide whether or not to operate and imaging should not be withheld particularly in case of suspected appendicitis which has a high risk of complications.

    Full Text Available Erica Schipper,1 Camran Nezhat21Center for Minimally Invasive and Robotic Surgery, Palo Alto, CA; 2Obstetrics/Gynecology and Surgery, Stanford University Medical Center, Palo Alto, CA, USAAbstract: Endometriosis is a highly enigmatic disease with multiple presentations ranging from infertility to severe pain, often causing significant morbidity. 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

    Background The purpose of this study was to evaluate the adoption of laparoscopic colon surgery and assess its impact in the community at large. Study Design The Surgical Care and Outcomes Assessment Program (SCOAP) is a quality improvement (QI) benchmarking initiative in the Northwest using medical record-based data. We evaluated the use of laparoscopy and a composite of adverse events (CAE; death or clinical reintervention) for patients undergoing elective colorectal surgery at 48 hospitals from 4th quarter of 2005 through 4th quarter of 2010. Results Of the 9,705 patients undergoing elective colorectal surgeries (mean age 60.6 ± 15.6 (SD) yrs; 55.2% women), 38.0% were performed laparoscopically (17.8% laparoscopic procedures converted to open). The use of laparoscopic procedures increased from 23.3% in 2005 quarter 4 to 41.6% in 2010 quarter 4 (trend over study period, plaparoscopy. Within those hospitals that had been in SCOAP since 2006, hospitals where laparoscopy was most commonly used also had a significant increase in the volume of all types of colon surgery (202 cases per hospital in 2010 from 112 cases per hospital in 2006, 80.4% increase), and in particular the number of resections for non-cancer diagnoses and right sided pathology. Conclusions The use of laparoscopic colorectal resection increased in the Northwest. Increased adoption of laparoscopic colectomies was associated with greater use of all types of colorectal surgery.

    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.

    Full Text Available Purpose: To report a case of combined laparoscopic and carbon dioxide partial cystectomy and foreign body removal and to review the existing literature on the topic. Materials and Methods: A 43-year-old Asian woman was found to have an intrauterine device embedded in the bladder wall during evaluation for chronic pelvic pain and urinary tract infection. She underwent cystoscopic-laparoscopic partial cystectomy, with an uncomplicated postoperative course. She had normal renal function during the follow-up period. This case demonstrates the possibility and safety of performing cystoscopic-laparoscopic partial cystectomy for the removal of a partially implanted intravesical foreign body. Results: The patient recovered without incident and was discharged 7 days after surgery. No abnormalities were noted in the urine output or renal function in the postoperative follow-up period. No complications due to retrograde flow of carbon dioxide up the ureters or air embolism were noted during the procedure or postoperatively. Conclusions: The combination of laparoscopy and air cystoscopy has been shown to be an optimal method for retracting foreign bodies embedded in the bladder wall. Also, air cystoscopy can be used to give doctors a better view in cases in which vision is compromised under water-contrast cystoscopy.

    The conventional incision for donor hepatectomy is a right subcostal incision with a midline extension. With increased experience in both donor hepatectomy and laparoscopy, the conventional incision can be shortened to a significant extent. Laparoscopic mobilization of the liver coupled with a hand port allows the insertion of one hand inside the abdomen for control; this makes small-incision donor hepatectomy a technically feasible alternative. We compared 26 right lobe donor hepatectomies performed with a laparoscopy-assisted technique (the laparoscopy-assisted donor hepatectomy group) to 24 donor hepatectomies performed with the conventional open technique (the conventional donor hepatectomy group). The donors in both groups and their recipients were followed for 6 months. Pain, discomfort related to the scar [including abdominal wall sensorineural deficits (numbness and differences in tactile and temperature sensations) and tightness around the scar], and donor quality of life (assessed with the International Quality of Life Assessment Short Form 8 scoring system) were compared between the 2 groups. In conclusion, laparoscopy-assisted surgery can be a technically feasible alternative in experienced hands, and as with other minimally invasive surgeries, it has advantages such as significantly less pain, reduced incision-related complications, and better donor quality of life during the early postoperative period without compromising donor safety. © 2014 American Association for the Study of Liver Diseases.

    This study aimed at evaluating the voiding patterns of adult patients who underwent hypospadias repair in childhood. Following IRB approval 103 (22.7%) of 449 adult patients who underwent hypospadias repair between 1978 and 1993 responded to the following questionnaires: International Prostate Symptom Score (I-PSS) and Short Form 12 questionnaire (SF-12). Uroflowmetry (UF) was performed for all patients. The patients were divided into three groups according to the primary meatus localization. Group I had 63 patients (61.5%) treated for glanular hypospadias, group II had 19 patients (18.4%) treated for distal hypospadias, and group III comprised the remaining 21 patients (20.4%) treated for proximal hypospadias. The mean ± SD I-PSS score for all patients who responded to the questionnaire was 2.3 ± 2.4, and UF was 21.1 ± 4.3 mL/s. The patients from groups I and III had fewer urinary symptoms compared with those of the group II: 1.3 ± 1.5, 5.5 ± 2.4, and 1.6 ± 1.4, respectively (p hypospadias repair in childhood had normal or mild voiding disturbance, with no effects on their physical or mental status.

    We investigated into association of quality of life(QOL)and prognosis of breast cancer patients who underwent neoadjuvant chemotherapy(NAC). We retrospectively studied 228 patients with breast cancer who were performed NAC during a period between 2007 and 2015. TheQ OL score was measured with"The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs(QOL-ACD)". We evaluate association between QOL score with antitumor effect and prognosis. Changes in the QOL score between before and after NAC were compared as well. We divided 2 groups by QOL-ACD scoreinto high and low groups. Therapeautic effect of NAC on 75 patients were pathological complete response(pCR). QOL-ACD score was not significantly associated with pCR rate in both high and low groups(p=0.199). High group was significantly associated with higher survival rate in both of disease free survival(p=0.009, logrank)and overall survival(p=0.040, logrank). QOLACD score decreased after NAC in both of pCR and non-pCR patients. In conclusion, QOL evaluation using QOL-ACD could be an indicator of breast cancer patients' prognosis who underwent NAC.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    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.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Controversy exists regarding the role of laparoscopy in the evaluation of patients with penetrating abdominal trauma (PAT). Our objective was to perform a comprehensive review of the literature and conduct a meta-analysis to compare outcomes of laparoscopy and laparotomy in PAT. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, we conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the Cochrane Central Register of Controlled Trials (CENTRAL); the World Health Organization International Clinical Trials Registry; ClinicalTrials.gov; ISRCTN Register, and bibliographic reference lists. We applied a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits in each of the above databases. Missed injury, mortality, and complications were defined as the primary outcome parameters. Procedure time, length of hospital stay, sensitivity and specificity of the procedure were the secondary outcomes. Combined overall effect sizes were calculated using fixed-effect or random-effects models. We identified one randomised controlled trial (RCT) and 8 observational studies comparing outcomes of laparoscopy with laparotomy in PAT. Laparoscopy was associated with a significantly lower risk of wound infection (Odd ratio (OR): 0.55; 95% Confidence interval (CI), 0.37-0.81, P = 0.003) and pneumonia (OR: 0.22; 95% CI, 0.13-0.37, P Laparoscopy was 100% sensitive in most of the included studies and avoided non-therapeutic laparotomies in 45.6% of patients. Our analysis of best available evidence mainly from heterogeneous observational studies has demonstrated that laparoscopic evaluation of haemodynamically stable patients with PAT may be safe and can reduce post-operative complications and length of hospital stay. The most important advantage of laparoscopy is avoidance of non-therapeutic laparotomies which are

    Diagnostic laparoscopy (DL) has decreased the rate of nontherapeutic laparotomy for patients suffering from penetrating injuries. We evaluated whether DL similarly lowers the rate of nontherapeutic laparotomy for patients with blunt injuries. All patients undergoing DL over a 10-year period (ie, 2001-2010) in a single level 1 trauma center were classified by the mechanism of injury. Demographic and perioperative data were compared using the Student t and Fisher exact tests. There were 131 patients included, 22 of whom sustained blunt injuries. Patients suffering from blunt injuries were more severely injured (Injury Severity Score 18.0 vs 7.3, P = .0001). The most common indication for DL after blunt injury was a computed tomographic scan concerning for bowel injury (59.1%). The rate of nontherapeutic laparotomy for patients sustaining penetrating vs blunt injury was 1.8% and nil, respectively. DL, when coupled with computed tomographic findings, is an effective tool for the initial management of patients with blunt injuries. Copyright © 2013 Elsevier Inc. All rights reserved.

    The implementation of the multidisciplinary team conference has been shown to improve treatment outcome for patients with gastric- and gastroesophageal cancer. Likewise, the staging laparoscopy has increased the detection of patients with disseminated disease, that is, patients who do not benefit from a surgical resection. The aim of this study was to compare the multidisciplinary team conference's decision in respect of M-staging with the findings of the following staging laparoscopy. Patients considered operable and resectable within the multidisciplinary team conference in the period 2010-2012 were retrospectively reviewed. Patient data were retrieved by searching for specific diagnosis and operation codes in the in-house system. The inclusion criteria were as follows: biopsy-verified cancer of the esophagus, gastroesophageal junction or stomach, and no suspicion of peritoneal carcinomatosis or liver metastases on multidisciplinary team conference before staging laparoscopy. Furthermore, an evaluation with staging laparoscopy was required. In total, 222 patients met the inclusion criteria. Most cancers were located in the gastroesophageal junction, n = 171 (77.0%), and most common with adenocarcinoma histology, n = 196 (88.3%). The staging laparoscopy was M1-positive for peritoneal carcinomatosis in eight patients (16.7%) with gastric cancer versus nine patients (5.3%) with gastroesophageal junction cancer. Furthermore, liver metastases were evident in zero patients (0.0%) and four patients (2.3%) with gastric- and gastroesophageal junction cancer, respectively. The staging laparoscopy findings regarding peritoneal carcinomatosis were significantly different between gastric- and gastroesophageal junction cancers, p = 0.01. No significant differences were found regarding T-/N-stage or histological tumor characteristics between the positive- and negative-staging laparoscopy group.

    Minimally invasive liver surgery is a rapidly advancing field with demonstrated applicability to living donation. In this paper, we compare the safety and efficacy of laparoscopy-assisted donor right hepatectomy (LADRH) to open donor right hepatectomy (ODRH). We performed a retrospective, comparative analysis of 33 LADRH to the most recent 33 ODRH performed at our institution, evaluating donor complications, costs, and recipient outcomes. Donor demographics including age, gender, body mass index (BMI), and vascular and biliary anomalies were comparable. Donor complication rates were equivalent for LADRH and ODRH. Donor operative times were shorter for LADRH (LADRH 265 minutes, ODRH 316; P size, recipient patient or graft survival, or recipient vascular or biliary complications. Our experience suggests that LADRH compares favorably with ODRH with equivalent safety, resource utilization, and effectiveness. We believe that LADRH provides potential physical and psychological benefits without an adverse effect on outcomes.

    Arteriovenous malformations of the stomach are an uncommon cause of upper GI bleeding. We report a case of stomach arteriovenous malformation in an 85-year-old Asian man who presented with massive hematemesis. Initial esophagogastroduodenoscopy did not detect this lesion, but contrast multi-detector CT confirmed GI bleeding. Multi-detector CT revealed a mass of blood vessels underlying the submucosa that arose from the right gastroepiploic artery. Repeat esophagogastroduodenoscopy showed that the lesion was a submucosal tumor with erosion and without active bleeding in the lower body of the stomach on the greater curvature. We performed partial gastrectomy via laparoscopy-assisted surgery. The histopathological diagnosis was arteriovenous malformation. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    To demonstrate our technique of mini-laparoscopic adnexectomy or salpingectomy at the time of total laparoscopic hysterectomy (TLH). Step-by-step video demonstration of our technique. The advantages of laparoscopic surgery have been widely recognized, including improved visualization and exposure, reduced operative trauma owing to smaller incisions and gentler tissue handling, and faster postoperative recovery. Continuing technological developments have allowed the use of smaller-caliber instruments while maintaining a high standard of surgical performance. Mini-laparoscopy requires the use of 3-mm or smaller ports. The main advantage of mini-laparoscopy is the reduced incision size, which can translate into a lower incidence of incision-related complications such as postoperative pain, infection, and trocar site herniation, along with superior cosmetic results. Today, in younger patients, prophylactic salpingectomy can be considered instead of adnexectomy, taking into account the well-known benefits of ovarian conservation. Prophylactic salpingectomy involves Fallopian tube removal for primary prevention of epithelial carcinoma of the fallopian tubes, ovaries, and peritoneum in women undergoing pelvic surgery for another indication. Other advantages of this intervention are the avoidance of hydrosalpinx (which affects ∼30% women after hysterectomy), the 7.8% lifetime risk of revision surgery [1], tubal infection, and benign and malignant Fallopian tube tumors. Finally, salpingectomy has no known physiological side effects, is safe and feasible, does not worsen surgical outcomes, does not significantly increase the operative time, and is not related to increased rates of intraoperative and postoperative complications or readmission. The patient is a 44-year-old woman with a history of 2 previous cesarean sections with adenomyosis and endometriosis infiltration of the uterosacral ligaments. After discussion about the risks and benefits of ovarian conservation with

    To investigate the technical feasibility of optical biopsy (probe-based confocal laser endomicroscopy [pCLE]) during laparoscopy and by the vaginal route in the exploration of pelvic gynecological cancers. Prospective study including 31 patients undergoing laparoscopic hysterectomy (benign or malignant indication). Confocal microlaparoscopy (analysis of tubes, ovaries, and depending on the type de cancer, pelvic adenopathies) and optical biopsy of the endometrium were first carried out by the vaginal route under general anesthesia. The surgical procedure was then carried out. Thirty-one consecutive patients were included (16 for benign hysterectomy, 12 for endometrial cancer and 3 for ovarian carcinoma). pCLE offered dynamic pictures that were correlated with the histopathological images. pCLE provides high resolution imaging of cancerous and benign tissues in real-time similar to histopathological results. Both feasibility and safety were confirmed. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They were randomly divided into the EN group and the TPN group. The biochemical and clinical parameters were recorded and analyzed between the two groups. There was no significant difference in the nutritional status, liver and kidney function, and blood glucose levels between the TPN and EN groups on the preoperative day, the 1st and 3 rd postoperative days. However, on the 7th postoperative day, there was significant difference between the two groups in 24 h urinary nitrogen, serum levels of, total protein (TP), transferrin (TF), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transpeptadase (GGT), blood urea nitrogen (BUN) and creatinine (Cr). On the 14th postoperative day, there was a significant difference between the two groups in terms of urinary levels of 24 h nitrogen, TP, TF, retinol binding protein, ALT, AST, ALP, GGT, total bilirubin, direct bilirubin, BUN, Cr, and glucose. The incidence of delayed gastric emptying in the EN and TPN groups was 0% and 20%, respectively. Moreover, the incidence of pancreatic fistulas and hemorrhages in the EN group were 3.6% and 3.6%, versus 26.7% and 30% in the TPN group, respectively. EN is better than TPN for pancreatic cancer patients who received pancreaticoduodenectomy.

    . Despite having discussed personalized medicine for more than a decade, we still see that most drug prescriptions for severe chronic diseases are largely based on 'trial and error' and not on solid biomarker data. However, with the advance of molecular diagnostics and a subsequent increased understanding...... of disease mechanisms, things are slowly changing. Within the last few years, we have seen an increasing number of predictive biomarker assays being developed to guide the use of targeted cancer drugs. This type of assay is called companion diagnostics and is developed in parallel to the drug using the drug-diagnostic...... co-development model. The development of companion diagnostics is a relatively new discipline and in this review, different aspects will be discussed including clinical and regulatory issues. Furthermore, examples of drugs, such as the ALK and PD-1/PD-L1 inhibitors, that have been approved recently...

    Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE) who underwent computed tomography pulmonary angiography (CTPA). Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells’ criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1%) of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05). Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05). Frequency of all criteria of Wells’ criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05). The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05). Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

    The management of penetrating abdominal stab wounds has been the subject of continued reappraisal and controversy. In the present study a novel method which combines the use of diagnostic laparoscopy and DPL, termed laparoscopic diagnostic peritoneal lavage (L-DPL) is described Five trauma patients with penetrating injuries to the lower chest or abdomen were included. Standard videoscopic equipment is utilized for the laparoscopic trauma evaluation of the injured patient. When no significant injury is detected, the videoscope is withdrawn and 1000 mL of normal saline is infused through the abdominal trochar into the peritoneal cavity, and the effluent fluid studied for RBCs, WBC, amylase debry, bile as it is uced in regular diagnostic peritoneal lavage Laparoscopic peritoneal lavage (L-DPL) was then performed and proved to be negative in all 5 patients. RBC lavage counts above 100,000/mcrl were not considered as a positive lavage result, because the bleeding source was directly observed and controlled laparoscopically. All patients recovered uneventfully and were released within 3 days. This procedure combines the visual advantages of laparoscopy together with the sensitivity and specificty of DPL for the diagnosis of significant penetrating intra-abdominal injury, when the diagnostic strategy of selective consevatism for abdominal stab wounds is adopted. A method of laparoscopic diagnostic peritoneal lavage (L-DPL) in hemodynamically stable patients with penetrating lower thoracic or abdominal stab wounds is described. The method is especially applicable for trauma surgeons with only basic experience in laparoscopic technique. This procedure is used to obtain conclusive evidence of significant intra-abdominal injury, confirm peritoneal penetration, control intra-abdominal bleeding, and repair lacerations to the diaphragm and abdominal wall. The combination of laparoscopy and DPL afforded by the L-DPL method adds to the sensitivity and specificity of DPL, and

    Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    There are increasingly more patients seeking minimally invasive procedures, which have become more effective and safer in reducing the signs of facial aging. This study included 40 female adult patients who voluntarily underwent selected minimally invasive procedures (filling with hyaluronic acid and botulinum toxin injection) for facial rejuvenation. All patients were followed for a period of 6 months. They were evaluated with the use of questionnaires, a quality-of-life questionnaire (DLQI), the self-esteem scale of Rosenberg (EPM/Rosenberg), and a pain scale. The minimally invasive procedures resulted in improvement in quality of life and self-esteem, which were stronger the first 3 months after the procedures but remained at a higher level than that before treatment, even after 6 months. Hyaluronic acid with lidocaine in the formula is more comfortable for the patient as it makes the injection less painful.

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre. All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma. A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up. Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    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.

    During the past year the far-infrared or submillimeter diagnostic research program resulted in three major developments: (1) an optically pumped 0.385-μm D 2 O-laser oscillator-amplifier system was operated at a power level of 1 MW with a line width of less than 50 MHz; (2) a conical Pyrex submillimeter laser beam dump with a retention efficiency greater than 10 4 was developed for the ion temperature Thompson scattering experiment; and (3) a new diagnostic technique was developed that makes use of the Faraday rotation of a modulated submillimeter laser beam to determine plasma current profile. Measurements of the asymmetric distortion of the H/sub α/ (6563 A) spectral line profile show that the effective toroidal drift velocity, dv/sub two vertical bars i/dT/sub i/, may be used as an indicator of plasma quality and as a complement to other ion temperature diagnostics

    2014-04-01

    Early diagnosis of fungal infection is critical to effective treatment. There are many impediments to diagnosis such as a diminishing number of clinical mycologists, cost, time to result, and requirements for sensitivity and specificity. In addition, fungal diagnostics must meet the contrasting needs presented by the increasing diversity of fungi found in association with the use of immunosuppressive agents in countries with high levels of medical care and the need for diagnostics in resource-limited countries where large numbers of opportunistic infections occur in patients with AIDS. Traditional approaches to diagnosis include direct microscopic examination of clinical samples, histopathology, culture, and serology. Emerging technologies include molecular diagnostics and antigen detection in clinical samples. Innovative new technologies that use molecular and immunoassay platforms have the potential to meet the needs of both resource-rich and resource-limited clinical environments.

    The aim of this study was to evaluate the long-term outcomes of four patients with tracheal agenesis who underwent airway and esophageal/alimentary reconstruction. We reviewed the medical records of four long-term survivors of tracheal agenesis and collected the following data: age, sex, type of tracheal agenesis, method of reconstruction, nutritional management, and physical and neurological development. The patients consisted of three boys and one girl, who ranged in age from 77 to 109months. The severity of their condition was classified as Floyd's type I (n=2), II (n=1), or III (n=1). Mechanical respiratory support was not necessary in any of the cases. Esophageal/alimentary reconstruction was performed using the small intestine (n=2), a gastric tube (n=1), and the esophagus (n=1). The age at esophageal reconstruction ranged from 41 to 55months. All of the cases required enteral nutrition via gastrostomy. Three of the patients were able to swallow a small amount of liquid and one was able to take pureed food orally. The physical development of the subjects was moderately delayed-borderline in childhood. Neurological development was normal in two cases and slightly delayed in two cases. None of the long-term survivors of tracheal agenesis required the use of an artificial respirator, and their development was close to normal. Future studies should aim to elucidate the optimal method for performing esophageal reconstruction to allow tracheal agenesis patients to achieve their full oral intake.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB.

    Video thoracoscopic sympathectomy is the recommended surgical treatment for primary hyperhidrosis and has a high success rate. Despite this high success rate, some patients are unresponsive and eventually need a resympathectomy. Few studies have previously analysed exclusively the results of these resympathectomies in patients with primary hyperhidrosis. None of the studies have objectively evaluated the degree of response to surgery or the improvement in quality of life after resympathectomies. This is a retrospective study, evaluating 15 patients from an initial group of 2300 patients who underwent resympathectomy after failure of the primary surgical treatment. We evaluated sympathectomy levels of resection, technical difficulties, surgical complications preoperative quality of life, response to treatment and quality-of-life improvement 30 days after each surgery. Regarding gender, 11 (73.3%) patients were women. The average age was 23.2 with SD of 5.17 years, and the mean body mass index was 20.9 (SD 2.12). Ten patients had major complaints about their hands (66%) and 5 (33%) patients about their forearms. A high degree of response to sympathectomy occurred in 73% of patients. In 11 of these patients, the improvement in quality of life was considered high, 3 showed a mild improvement and 1 did not improve. No major complications occurred; the presence of adhesions was reported in 11 patients and pleural drainage was necessary in 4 patients. Resympathectomy is an effective procedure, and it improves the quality of life in patients with primary hyperhidrosis who failed after the first surgery. © The Author 2017.

    The study objective was to report the outcomes of biventricular repair in patients with double outlet right ventricle. Patients with double outlet right ventricle who underwent biventricular repair at Fuwai Hospital from January 2005 to December 2012 were included. Patients were excluded if double outlet right ventricle was combined with atrioventricular septal defect, heterotaxy syndrome, atrioventricular discordance, or univentricular physiology. A total of 380 consecutive patients with a mean age of 1.9 ± 2.1 years (range, 1 month to 6 years) were included. Varied types of biventricular repair were customized individually. Follow-up was 90.4% complete, and the mean follow-up time was 3.4 ± 3.9 years. There were 17 (4.5%) early deaths and 7 (2.1%) late deaths. Preoperative pulmonary hypertension was the only risk factor for early mortality. Postoperative significant left ventricular outflow tract obstruction was present in 9 survivors. Patients with noncommitted ventricular septal defect had a longer crossclamp time, longer cardiopulmonary bypass time, and higher incidence of postdischarge left ventricular outflow tract obstruction. There were 4 reoperations, all of which were caused by subaortic left ventricular outflow tract obstruction. All of the pressure gradients were decreased to less than 20 mm Hg after the modified Konno procedure with an uneventful postoperative course. Optimal results of varied types of biventricular repair for double outlet right ventricle have been acquired. Although noncommitted ventricular septal defect is technically difficult, the outcomes of patients are favorable. Late-onset left ventricular outflow tract obstruction is the main reason for reoperation but can be successfully relieved by the modified Konno procedure.

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

    Background Gastric cancer is a common malignancy worldwide and a common cause of death from cancer. Despite recent advances in multimodality treatment and targeted therapy, complete resection remains the only treatment that can lead to cure. This study was devised to investigate the technical feasibility, safety and oncologic efficacy of laparoscopy-assisted gastrectomy for advanced gastric cancer without serosa invasion. Methods A retrospective matched cohort study was performed in south China comparing laparoscopy-assisted gastrectomy and open gastrectomy for advanced gastric cancer without serosa invasion. Eighty-three patients with advanced gastric cancer undergoing laparoscopy-assisted gastrectomy between January 2008 and December 2010 were enrolled. These patients were compared with 83 patients with advanced gastric cancer undergoing open gastrectomy during the same period. Results There was no significant difference in clinicopathologic characteristics between the two groups. Regarding perioperative characteristics, the operation time and time to ground activities did not differ between the two groups, whereas the blood loss, transfused patient number, time to first flatus, time to resumption of diet, and postoperative hospital stay were significantly less in laparoscopy-assisted gastrectomy than in open gastrectomy (P Laparoscopy-assisted gastrectomy with D2 lymphadenectomy is a safe and feasible procedure for advanced gastric cancer without serosa invasion. To be accepted as a choice treatment for advanced gastric cancer, well-designed randomized controlled trials comparing short-term and long-term outcomes between laparoscopy-assisted gastrectomy and open gastrectomy in a larger number of patients are necessary.

    Full Text Available Goats (n=12 undergoing laparoscopy assisted embryo transfer were randomly allotted to two groups (I and II and injected lignocaine hydrochloride (4mg/kg or ropivacaine hydrochloride (1mg/kg at the lumbosacral epidural space. The animals were held with raised hind quarters for first three minutes following injection. Immediately after induction of regional anaesthesia, they were restrained in dorsal recumbency in Trendelenburg position in a cradle. Laparoscopy was performed after creating pneumoperitoneum using filtered room air. The mean (± S.E induction time in animals of group I was significantly shorter (5.33 ± 0.61 min than those belonging to group II (12.66 ±1.99 min. Complete analgesia developed throughout the hind quarters and abdomen for 30 min and 60 min in group I and II animal’s respectively. Unlike animals of group I, group II goats continued to show moderate analgesia for 180 minutes. The motor activity returned after a lapse of 130.00 ± 12.64 min and 405.00 ± 46.31 min respectively. Occasional vocalization and struggling was noticed in two goats one from each group irrespective of the surgical manipulations during laparoscopy. The rectal temperature and respiration rates showed only non-significant increase, but the heart rate values were significantly higher (P < 0.5 up to 150 min in animals of both the groups when compared to their baseline values. From this study, it was concluded that both anaesthetic agents produced satisfactory regional anaesthesia in goats undergoing laparoscopy. However, considering the very long delay in regaining the hind limb motor activity, the use of ropivacaine may not be recommended for this purpose. Supplementation of sedative/tranquilizer with lumbosacral epidural anaesthesia needs evaluation.

    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.

    Background Because of the high prevalence of obesity, there is a growing demand for bariatric surgery worldwide. The objective of this systematic review was to analyze the difference in relation to cost-effectiveness of access route by laparoscopy versus laparotomy of Roux en-Y gastric bypass (RYGB). Methods A systematic review was conducted in the electronic databases MEDLINE, Embase, Scopus, Cochrane and Lilacs in order to identify economic evaluation studies that compare the cost-effectiveness of laparoscopic and laparotomic routes in RYGB. Results In a total of 494 articles, only 6 fulfilled the eligibility criteria. All studies were published between 2001 and 2008 in the United States (USA). Three studies fulfilled less than half of the items that evaluated the results quality; two satisfied 5 of the required items, and only 1 study fulfilled 7 of 10 items. The economic evaluation of studies alternated between cost-effectiveness and cost-consequence. Five studies considered the surgery by laparoscopy the dominant strategy, because it showed greater clinical benefit (less probability of post-surgical complications, less hospitalization time) and lower total cost. Conclusion This review indicates that laparoscopy is a safe and well-tolerated technique, despite the costs of surgery being higher when compared with laparotomy. However, the additional costs are compensated by the lower probability of complications after surgery and, consequently, avoiding their costs. PMID:24945704

    Umbilical laparoendoscopic single-site (LESS) surgery is an increasingly used modality for treating renal masses. We present a prospective comparison between LESS renal surgery and conventional laparoscopy. A comparative paired study was conducted that evaluated the surgical results and complications of patients with renal neoplasia treated with LESS surgery (n=49) or multiport laparoscopy (n=53). The LESS approach was performed with reusable material placed in the navel and double-rotation curved instruments. An additional 3.5-mm port was employed in 69.4% of the cases. We assessed demographic data, the type of technique (nephrectomy, partial nephrectomy and nephroureterectomy), surgical time, blood loss, haemoglobin, need for transfusion, number and severity of complications (Clavien-Dindo), hospital stay, histological data and prognosis. There were no differences in follow-up, age, sex, body mass index, preoperative haemoglobin levels or type of surgery. Conversion occurred in 2 cases (1 in each group). The surgical time was equivalent (P=.6). Intraoperative transfusion (P=.03) and blood loss (Plaparoscopy (P=.0013). Umbilical LESS surgery with reusable platform enables various surgical techniques to be performed when treating renal masses, with time consumption and safety comparable to conventional laparoscopy. The LESS approach is advantageous in terms of blood loss and hospital stay. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    The efficacy and safety of treating elderly patients with colorectal cancer (CRC) is of concern. This study aimed to compare the short- and long-term outcomes of elective laparoscopic vs. open surgery to treat CRC in very elderly patients. All patients aged >80 years and who had undergone a colectomy for CRC without metastasis between July 2005 and April 2012 were considered for inclusion. Demographic, clinical, operative, and postoperative data, plus overall and disease-free survival rates, were retrospectively collected and compared between two groups of patients that underwent an open procedure (OP group) or laparoscopy (LG). 123 patients were enrolled (55 OPG, 68 LG). Median age was similar between the groups (84 vs. 83 years, respectively; NS). Duration of surgery was significantly lower in OPG (170 vs. 200min; p=0.030). Overall mortality at 3 months was 8.3%: it tended to be greater in the OPG (16.5% vs. 1.5%, NS). Morbidity was significantly greater in the OPG compared to the LG (52.7% vs. 27.5%; p=0.021), resulting in significantly longer hospital stay (12 vs. 8 days, respectively; plaparoscopy (85% and 72%) compared to open surgery (58.2% and 48%, respectively; plaparoscopy is safe and could increase overall survival compared to open surgery in elderly patients suffering from CRC. This retrospective study compared the short- and longer-term outcomes of patients aged >80 years and undergoing elective laparoscopic or open surgery for CRC between 2005 and 2012.

    Recently, studies have focused on how to optimize laparoscopic surgical workspace by changes in intra-abdominal pressure, level of muscle relaxation or body position, typically evaluated by surgeons using subjective rating scales. We aimed to validate two rating scales by having surgeons assess surgical workspace in video sequences recorded during laparoscopic surgery. Video sequences were obtained from laparoscopic procedures. Eight experienced surgeons assessed the video sequences on a categorical 5-point scale and a numerical 10-point rating scale. Intraclass correlations coefficients (ICC) and 95% confidence intervals (CI) were calculated for intra- and inter-rater reliability. The 5-point rating scale had an intra-rater ICC of 0.76 (0.69; 0.83) and an inter-rater ICC of 0.57 (0.45; 0.68), corresponding to excellent and fair reliability, respectively. The 10-point scale had an intra-rater ICC of 0.86 (0.82; 0.89) and an inter-rater ICC of 0.54 (0.39; 0.68), corresponding to excellent and fair as well. All surgeons used the full range of the 5-point scale, but only one surgeon used the full range of the 10-point scale. In conclusion, both scales showed excellent intra-rater and fair inter-rater reliability for assessing surgical workspace in laparoscopy. The 5-point surgical rating scale had all categories employed by all surgeons. © 2017 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    The purpose of this study was to validate the therapeutic efficacy of the innovative surgical approach using laparoscopy, atelocollagen sponge, and hand-made mould on the achievement of a satisfactory neovagina in patients with vaginal agenesis. The current study involved four patients diagnosed as having Mayer-Rokitansky-Küster-Hauser syndrome. After creating a vaginal tunnel, the mould wrapped with atelocollagen sponge was placed within the neovagina. The hand-made mould made of expanded polystyrene was started to insert into the neovagina at 7 days after operation. Since this mould is lighter and easier to adjust compared with the previous commercialized ones, it was less stressful for the patients to master the procedure than previous methods. Average operation time was 124 minutes with average blood loss being 45 ml. Average hospital stay was 23 days. The mean length of the neovagina one week postoperation was 8 cm with two fingers in width in all patients. No remarkable postoperative complications were noted. At two months after surgery, the neovagina was confirmed to be completely epithelialized in all patients, assessed by Schiller's test. This innovative surgical procedure using a mould wrapped with atelocollagen sponge may be a more useful approach for the treatment of vaginal agenesis.

    For virtual reality laparosopic simulation we developed a new, highly immersive simulation mode. The goal of the current pilot study was to investigate if kinetosis or other negative vegetative side effects can be caused by a total virtual training set-up (TVRL). In this study 20 participants with varying degrees of expertise in laparoscopy performed 3 tasks (i.e. ring exchange, fine dissection and cholecystectomy) in regular (VRL) and immersive mode (TVRL) with a head-mounted display (HMD) on a laparoscopic simulator. Aside from performance scores, the heart rate was recorded and the occurrence of vertigo was investigated. Surgical performance was independent of the VR mode (VRL or TVRL). Participants' heart rate was higher in TVRL without reaching statistical significance. Kinetosis occurred in two participants (10%) with a history of motion sickness. Laparoscopic training can take place in a total virtual environment with limited nagative vegetative side effects. Special attention should be paid to participants with a history of motion sickness. The development of TVRL enables new perspectives for surgical training.

    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.

    Single-site laparoscopy (SSL) attempts to further reduce the surgical impact of minimally invasive surgery. However, crossed instruments and the proximity of the endoscope to the operating instruments placed through one single site leads to inevitable instrument or trocar collision. We hypothesized that a novel, single-port, triangulating surgical platform (SPSP) might enhance performance by improving bimanual coordination and decreasing the surgeon's mental workload. Fourteen participants, proficient in basic laparoscopic skills, were tested on their ability to perform a validated intracorporeal suturing task by either an SSL approach with crossed articulated instruments or a novel SPSP, providing true-right and true-left manipulation. Standard laparoscopic (SL) access served as control. Sutures were evaluated using validated scoring methods and the National Aeronautics and Space Administration Task Load Index was used to rate mental workload. All participants proficiently performed intracorporeal knots by SL (mean score 99.0; 95% CI 97.0 to 100.9). Performance decreased significantly (more than 50%, p mental workload when using true-right and true-left manipulation. This study objectively assessed SSL performance and current attempts for instrumentation improvement in single-site access. While SSL significantly impairs basic laparoscopic skills, surgical platforms providing true-left and true-right maneuvering of instruments appear to be more intuitive and address some of the current challenges of SSL that may otherwise limit its widespread acceptance.

    The aim of this study was to compare the outcomes of robotic surgery, laparoscopy, and laparotomy for the surgical treatment of stage IA to IIB cervical cancer. This retrospective study was carried out in a university-affiliated teaching hospital. A total of 100 women with an initial diagnosis of stage IA to IIB cervical cancer, without preoperative brachytherapy or chemotherapy, were included in this study. With selection of the cases, 44 patients received laparotomy surgery, 32 patients received laparoscopic surgery, and 24 patients received robotic surgery. The perioperative parameters measured included operation time, blood loss, transfusion rate, lymph node yield, adhesion score, laparotomy conversion rate, postoperative and 24-hour pain scores, time to full diet resumption, and hospital stay. The perioperative complication and disease-free survival were also evaluated. The robotic group showed a shorter operation time, less blood loss, lower transfusion rate, and lower laparotomy conversion rate than the laparoscopic or laparotomy group. As for the postoperative parameters, the robotic group showed reduced postoperative and 24-hour pain scores, shortened length of hospital stay, and decreased time to full diet resumption compared with the other 2 surgical groups. No significant differences were found between the groups in perioperative complication rate or disease-free survival. The data suggested that robotic surgery is a feasible and potentially optimal option for the treatment of stage IA to IIB cervical cancer with favorable short-term surgical outcomes.

    Light-emitting diodes (LEDs) bring great flexibility in color choice and high luminous efficacy design for biomedical illumination. Based on the state-of-the-art LED chips, a three-chip LED illumination system was developed specially for laparoscopy and minimal access surgery. White light is produced by mixing three specific wavelengths of amber red, true green and blue, and then coupled into a fiber-optic light guide with 2mm diameter. The whole device has a compact size of 145mm × 92mm × 84 mm which is more suitable than a conventional xenon lamp source for portable endoscopes. The illuminance and color characteristic of the three-chip model were analyzed, compared to those of traditional light source. A maximum illuminance of 1960 lux was obtained at the distance of 100 mm, with the average current of 450 mA of the LEDs. Additionally, a simulation environment had been set up to find out the performance of the endo-illuminator in the specific circumstance, which was closer distance and crawl space. Experiments showed that images taken under the three-chip LED illumination had better contrast and saturation. With the temperature of 31.5 degrees Celsius at the end of the fiber bundle, the endo-illuminator is also a cold light source.

  10. PATIENT POSITION AS A POSSIBLE RISK FACTOR FOR POSTOPERATIVE NAUSEA AND VOMITING (PONV IN GYNECOLOGIC LAPAROSCOPY

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Postoperative nausea and vomiting (PONV are still a significant problem in modern anesthetic practice. Discomfort caused by PONV intensifies other unpleasant elements of recovery, such as pain, frustration or fear. PONV also generates aversion to future anesthesia and have a negative impact on staff and patient's family. PONV can increase the cost of completing a surgical procedure, because it extends the time a patient spends in the postanesthesia care unit (PACU or delay discharge of ambulatory patients. It is generally accepted that the incidence of PONV after general anesthesia for various types of surgery in the last decade is still between 20-30%, and 70% in laparoscopic abdominal surgery. The incidence is three times higher in females compared to males. Many factors are involved in triggering PONV, such as patientrelated factors, the type of surgery, anesthesia management, etc. The results of this study suggest that the patient positioning (modified supine lithotomy position with ''Trendelenburg" increases the risk of PONV in gynecologic laparoscopy.

    Full Text Available Introduction: Due to the growing economical and ethical limitations in surgeons training for minimally invasive surgery (mis, e.g. laparoscopy, this study aims at evaluating the effect of a continuous practice of a particular videogame on the development of the fundamental and specific skills needed to perform this type of procedure successfully. Materials and methods: To evaluate the effectiveness of video game practicing, three essential and common activities were chosen (cutting, suturing, and eye-hand coordination to be performed in laparoscopic simulators. Eight different indexes or variables of performance were measured in the three activities. Fourteen voluntaries without previous experience in surgery were divided in two groups (intervention and control and their performance was evaluated before and after a one-month standardized training program with the video game Marble Mania®. Results: A general improvement of all the performance variables was observed after one month training in the intervention group. This improvement was significant with respect to the control group in three of the eight variables: suturing errors (p = 0.003, and the execution and number of errors in the eye-hand coordination (p = 0.025 and 0.001, respectively.

    Despite advances in imaging techniques, peritoneal and/or metastatic disease have been identified by staging laparoscopy in up to 50 % of patients with a negative preoperative imaging. Neutrophil to lymphocyte ratio (NLR) has been recently shown as a prognostic factor in gastric and esophageal cancers. We retrospectively reviewed the medical records of 117 patients with early gastric and lower esophagus adenocarcinoma that were referred for staging laparoscopy in the last two years in the University College Hospital, London. Complete blood count was performed preceding staging laparoscopy. The NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count; a high NLR was defined ≥3.28. We evaluated the predictive power of a high NLR for a positive staging laparoscopy. The median age was 66.7 years; 87 (74.4 %) were male. Forty-four percent of the tumors were located at the gastroesophageal junction, 18 % were esophageal, and 38 % were gastric. Twenty-five (21.4 %) patients were found to have peritoneal or metastatic disease on staging laparoscopy. NLR ≥3.28 was an independent predicting factor for the discovery of peritoneal and/or metastatic disease (OR 3.9, 95 % CI: 1.54-9.86, p = 0.005). The median value of NLR was significantly higher in patients for whom the laparoscopy had discovered peritoneal or metastatic disease, than in those it had not (3.3 vs. 2.2, p = 0.011). Our findings suggest that the NLR may be reliable for predicting the presence of peritoneal or metastatic involvement on staging laparoscopy, in patients with early gastric cancer or lower esophageal cancer.

  13. Periodontal diagnostics.

    Periodontitis affects a subset of the population and our current thinking is that progression of periodontal disease may be either continuous or cyclical (burst hypothesis). These features make screening and diagnostic tools desirable in the management of this disease. Although many potential markers exist, several difficulties hamper our ability to declare them diagnostic tests with proven utility. The 'gold standard' for active periodontal disease is not available and inflammation due to gingivally confined lesions (gingivitis) and periodontal inflammation which results in attachment loss is a potential confounder of any test based on assessing the host response elements of the disease. The current absence of proof for the progression of periodontal disease i.e., whether or not the burst hypothesis is correct, is a further problem. Although much is written about the need for markers of current or future disease which will prevent us from overtreating pockets, the time, effort and cost involved in testing these sites has to be balanced against the relative ease and speed of routine therapy such as root planing. In addition, we are still some way from the development and validation of reliable host or microbial testing methods. In terms of screening tests for diseases such as the early-onset forms of periodontitis, the research and development on diagnostic tools involving genetic polymorphisms, specific genes, systemic antibodies or leucocyte cell surface markers of the patients, may become a clinical reality in time. One could envisage chairside tests using blood from thumb pricks being capable of determining a young individual's risk of developing disease at a later age, and thus the need for a timely prevention programme. Before applying any test we should reconsider what treatment planning effects a positive or negative result will have, and any test which does not influence the treatment plan is redundant. Whether periodontal diagnostic tests will be

    Purpose: To compare the diagnostic value of dual-phase multidetector-row CT (MDCT) and MR imaging with dual-phase three-dimensional MR angiography (MRA) in the prediction of vascular involvement and resectability of pancreatic ductal adenocarcinoma. Methods and materials: 116 patients with proven pancreatic adenocarcinoma underwent both MDCT and combined MR imaging prior to surgery. Of 116 patients, 56 who underwent surgery were included. Two radiologists independently attempt to assess detectability, vascular involvement and resectability of pancreatic adenocarcinoma on both images. Results were compared with surgical findings and statistical analysis was performed. Results: MDCT detected pancreatic mass in 45 of 56 patients (80.3%) and MR imaging in 44 patients (78.6%). In assessment of vascular involvement, sensitivities and specificities of MDCT were 61% and 96% on a vessel-by-vessel basis, respectively. Those of MR imaging were 57% and 98%, respectively. In determining resectability, sensitivities and specificities of MDCT were 90% and 65%, respectively. Those of MR imaging were 90% and 41%, respectively. There was no statistical difference in detecting tumor, assessing vascular involvement and determining resectability between MDCT and MR imaging (p = 0.5). Conclusion: MDCT and MR imaging with MRA demonstrated an equal ability in detection, predicting vascular involvement, and determining resectability for a pancreatic ductal adenocarcinoma.

    The diagnostic methods of tubal factor in infertility have been presented. In details have been discussed PJ, PK HSG and pelviscopy. These examinations themselves constitute the basic ones in infertility. We turned our attention into technical details and possible mistakes which may occur at the time of performing them, these misinterpretations may lead to absolutely wrong conclusion and diagnosis. Authors have wide experience in performing the discussed examinations and this allows them to share their opinion. Over the years several thousand of PK and HSG examinations have been carried out and also 1000 laparoscopies. (author)

    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.

    In 2005, the general population of Mongolia was not aware of laparoscopic surgery and was skeptical about the safety of surgical care. A 9-year initiative to expand laparoscopic surgery was initiated by Mongolian surgeons. This study examines the current barriers to and perceptions of surgical care following laparoscopic surgical expansion countrywide. In September 2013, interviews were conducted with 71 patients, and 39 physicians in Mongolia. Patients and physicians were interviewed using separate sets of interview questions. Questions were designed to gauge perceptions of surgical care in Mongolia evaluating for access, affordability, sustainability, barriers to care, quality, and knowledge of laparoscopy. Responses were fine coded for statistical analysis. 79 % of patients felt surgical care was improving in Mongolia, and 76 % would choose laparoscopy if available. Physicians (100 %) felt laparoscopic surgery had improved surgical care in Mongolia. Barriers to care for patients were time to work up and diagnosis (37 %), and funding an operation (39 %). None of the 36 % of patients who stated funding an operation would be difficult identified government sources of funding (p laparoscopy. 74 % of physicians felt that Mongolian physicians return or stay in Mongolia after training, defying the trend of migration in low-resource settings. Improved local patient and physician perception of laparoscopy is propelling the expansion of laparoscopy in Mongolia.

    In this study we aimed to assess the feasibility and safety of fast-track surgery (FTS) combined with laparoscopy for treating patients with rectal cancer and compare the results with those of the conventional perioperative intervention group. A total of 120 patients with rectal cancer were prospectively randomly assigned to the FTS combined with laparoscopy group and the conventional perioperative intervention plus laparoscopy group from November 2011 to November 2012. All patients received radical anterior resection with total mesorectal excision. Their baseline characteristics and the perioperative outcomes were recorded for analyses. Compared with the conventional perioperative intervention group, the fast-track protocol combined with laparoscopy could shorten the time to the first flatus (53.44 ± 23.64 h vs 67.85 ± 20.12 h, P = 0.001) and first defecation (65.23 ± 22.24 h vs 86.98 ± 24.85 h, P = 0.000) after operation, accelerate the decrease of white blood cell count (P laparoscopy may accelerate the clinical recovery of patients with rectal cancer after surgery. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    We compared laparoscopy-assisted Duhamel (Lap-D) with open surgery (Duhamel or Soave = D/S) for treating total colonic aganglionosis (TCA) in children to establish what factors may affect outcome. Fourteen TCA cases treated between 1990 and 2010 were reviewed. Open D/S (O-D/S) through a vertical midline abdominal incision was routine from 1990 to 2005, whereupon Lap-D became routine. Lap-D involves laparoscopic colon resection, ileostomy take-down, and ileum pull-through through an additional Pfannenstiel incision. We compared pre-operative nutrition, operating time, intraoperative blood loss, duration until oral challenge, postoperative analgesic usage, incidence of enterocolitis, early complications that arose within 30 days of surgery, and late complications, and wound cosmesis 1 year postoperatively (Grade-1: unacceptable, Grade-2: passable, Grade-3: excellent). Six had O-D/S (2D, 4S) and eight had Lap-D. Differences in patient demographics, mean ages/weights at surgery, average length of the aganglionic segment from the terminal ileum, operating time, and time taken for oral challenge were all not significant, full feeding took longer in O-D/S (6.7 vs. 5.9 days). Preoperative central vein intravenous hyperalimentation was required for one case in O-D/S and two cases in Lap-D. These three required hospitalization for at least 30 days postoperatively and parenteral nutrition after discharge. Although there were no intraoperative complications in either group, there was one case of transient ileus in O-D/S that resolved conservatively. Cosmesis was significantly better in Lap-D (O-D/S = 1.2; Lap-D = 2.1; p < 0.05). Cosmesis was the only factor that was significantly different between Lap-D and O-D/S; all other factors were similar.

    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.

    Objective: To examine the potential utility of 3D-reconstructed sonograms to distinguish cirrhotic from non-cirrhotic livers by demonstrating hepatic surface characteristics. Materials and methods: A preliminary phantom study was performed to examine the potential resolution of 3D images, recognizing surface irregularities as a difference in height. In a prospective clinical study of 31 consecutive patients with ascites (21 cirrhosis, 10 non-cirrhosis), liver volume data were acquired by transabdominal mechanical scanning. The hepatic surface features of cirrhotic and non-cirrhotic patients were compared by 2 independent reviewers. Intra- and inter-operator/reviewer agreements were also examined. Results: The phantom study revealed that 0.4 mm was the minimum recognizable difference in height on the 3D sonograms. The hepatic surface image was successfully visualized in 74% patients (23/31). Success depended on the amount of ascites; visualization was 100% with ascites of 10 mm or more between the hepatic surface and abdominal wall. The images showed irregularity of the hepatic surface in all cirrhotic patients. The surface appearance was confirmed as being very similar in 3 patients who had both 3D sonogram and liver resection for transplantation. The ability to distinguish cirrhotic liver from non-cirrhotic liver improved with the use of combination of 2D- and 3D-imaging versus 2D-imaging alone (sensitivity, p = 0.02; accuracy, p = 0.02) or 3D-imaging alone (sensitivity, p = 0.03). Intra-/inter-operator and inter-reviewer agreement were excellent (κ = 1.0). Conclusion: 3D-based sonographic visualization of the hepatic surface showed high reliability and reproducibility, acting as a virtual laparoscopy method, and the technique has the potential to improve the diagnosis of cirrhosis.

    Aim The use of a minimally invasive approach to treat appendicitis has yet to be universally accepted. The objective of this study was to examine recent trends in Ireland in the surgical management of acute appendicitis. Method Data were obtained from the Irish Hospital In-Patient Enquiry system for patients discharged with a diagnosis of appendicitis between 1999 and 2007. An anonymous postal survey was sent to all general surgeons of consultant and registrar level in Ireland to assess current attitudes to the use of laparoscopic appendectomy. Results The use of laparoscopic appendectomy increased throughout the study and was the most common approach for appendectomy in 2007. Multivariate analysis revealed age under 50 years (OR = 1.51), female sex (OR = 2.84) and residence in high-density population areas (OR = 4.15) as predictive factors for undergoing laparoscopic appendectomy in the most recent year of the study. While 97% of surgeons reported current use of laparoscopy in patients with acute right iliac fossa pain, in most cases it was selective. Surgeons in university teaching hospitals (42 of 77; 55%) were more likely to report using laparoscopic appendectomy for all cases of appendicitis than those in regional (six of 23; 26%) or general (13 of 53; 25%) hospitals (P = 0.048). Conclusion This study has demonstrated a significant increase in laparoscopic appendectomy, yet a variety of patient and surgeon factors contribute to the choice of procedure. Differences in the perception of benefit of the laparoscopic approach amongst surgeons appears to be an important factor in determining the operative approach for appendectomy.

    OBJECTIVE Ventriculoperitoneal (VP) shunt treatment is the main treatment method for hydrocephalus. The traditional operative approach for peritoneal catheter insertion is mini-laparotomy. In recent years, laparoscopy-assisted insertion has become increasingly popular. It seems likely that use of an endoscope could lower the incidence of shunt malfunction. However, there is no consensus about the benefits of laparoscopy-assisted peritoneal catheter insertion. METHODS A systematic search was performed using the PubMed, Embase, ScienceDirect, and Cochrane Library databases. A manual search for reference lists was conducted. The protocol was prepared according to the interventional systematic reviews of the Cochrane Handbook, and the article was written on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. RESULTS Eleven observational trials and 2 randomized controlled trials were included. Seven operation-related outcome measures were analyzed, and 3 of these showed no difference between operative techniques. The results of the meta-analysis are as follows: in the laparoscopy group, the rate of distal shunt failure was lower (OR 0.41, 95% CI 0.25-0.67; p = 0.0003), the absolute effect is 7.11% for distal shunt failure, the number needed to treat is 14 (95% CI 8-23), operative time was shorter (mean difference [MD], -12.84; 95% CI -20.68 to -5.00; p = 0.001), and blood loss was less (MD -9.93, 95% CI -17.56 to -2.31; p = 0.01). In addition, a borderline statistically significant difference tending to laparoscopic technique was observed in terms of hospital stay (MD -1.77, 95% CI -3.67 to 0.13; p = 0.07). CONCLUSIONS To some extent, a laparoscopic insertion technique could yield a better prognosis, mainly because it is associated with a lower distal failure rate and shorter operative time, which would be clinically relevant.

    Diagnosis of pelvic inflammatory disease is difficult. We focus on a systematic literature review to study diagnostic values of history-taking, clinical examination, laboratory tests and imagery. After this literature review, we build a diagnostic model for pelvic inflammatory disease. This diagnostic model is built on two major criteria: presence of adnexal tenderness or cervical motion tenderness. Additional minor criteria, increasing the likelihood of the diagnosis of pelvic inflammatory disease were added based on their specificity and their positive likelihood ratio. These minor criteria are supported by history-taking, clinical examination, laboratory tests and also on relevant ultrasonographic criteria. Copyright © 2012 Elsevier Masson SAS.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    Full Text Available Endometriosis is characterized by endometrial tissue found outside of the uterus (primarily in the pelvic cavity, causing chronic inflammatory reaction, infertility, and pain. The impact of endometriosis on different aspects of women’s life is important, including family and social life, work, and reproduction. The usual way of examining endometriosis is history taking, recognition of typical symptoms, clinical examination, and the use of imaging techniques, but the diagnosis is made by histopathology findings, usually after laparoscopy. The aim is to represent current recommendations and guidelines referring to endometriosis diagnostics and therapy, proposed by two major societies dealing with reproductive medicine: European Society for Human Reproduction and Embryology (ESHRE and American Society of Reproductive Medicine (ASRM. The recommendations refer primarily to the therapeutic modalities in infertility and pain problems caused by endometriosis, and represent the basis of appropriate strategy for overcoming numerous problems linked with this chronic illness.

    In the acquisition of new skills that are difficult to master, such as those required for laparoscopy, feedback is a crucial component of the learning experience. Optimally, feedback should accurately reflect the task performance to be improved and be proximal to the training experience. In surgery, however, feedback typically is in vivo. The development of virtual reality training systems currently offers new training options. This study investigated the effect of feedback type and quality on laparoscopic skills acquisition. For this study, 32 laparoscopic novices were prospectively randomized into four training conditions, with 8 in each group. Group 1 (control) had no feedback. Group 2 (buzzer) had audio feedback when the edges were touched. Group 3 (voiced error) had an examiner voicing the word "error" each time the walls were touched. Group 4 (both) received both the audio buzzer and "error" voiced by the examiner All the subjects performed a maze-tracking task with a laparoscopic stylus inserted through a 5-mm port to simulate the fulcrum effect in minimally invasive surgery (MIS). A computer connected to the stylus scored an error each time the edge of the maze was touched, and the subjects were made aware of the error in the aforementioned manner. Ten 2-min trials were performed by the subjects while viewing a monitor. At the conclusion of training, all the subjects completed a 2-min trial of a simple laparoscopic cutting task, with the number of correct and incorrect incisions recorded. Group 4 (both) made significantly more correct incisions than the other three groups (F = 12.13; df = 3, 28; p < 0.001), and also made significantly fewer errors or incorrect incisions (F = 14.4; p < 0.0001). Group 4 also made three times more correct incisions and 7.4 times fewer incorrect incisions than group 1 (control). The type and quality of feedback during psychomotor skill acquisition for MIS have a large effect on the strength of skills generalization to a simple

    Sleep deprivation affects surgical performance and has the potential to endanger patient safety. Pharmacological stimulants may counter this consequence of long working hours. This study aimed to investigate whether commonly available stimulants can counter the effects of fatigue on technical and neurocognitive skill. This was a single-blind crossover study of surgical novices trained to proficiency on the Minimally Invasive Surgical Trainer-Virtual Reality laparoscopic simulator. Participants were acutely sleep-deprived three times each, followed by administration of either placebo, 150 mg caffeine, or 150 mg caffeine combined with 2 g taurine before simulated laparoscopy. Outcome measures were: laparoscopic psychomotor skill, cognitive performance and the Stanford Sleepiness Scale (range 1-7). Rested baselines were gathered following completion of test sessions. Baseline performance was recorded for 18 participants in the rested state. Sleep-deprived participants receiving the placebo took longer (median 41 versus 35 s; P = 0·016), were less economical with movement (3·25 versus 2·95 m; P = 0·016) and made more errors (66 versus 59; P = 0·021) on the laparoscopic task compared with the rested state. Caffeine restored psychomotor skills to baseline for time taken (37 versus 35 s; P = 0·101), although the number of errors remained significantly greater than in the rested state (63 versus 59; P = 0·046). Sleep-deprived subjects receiving placebo had slower reaction times (377 versus 299 ms; P = 0·008) and a higher score on the Stanford Sleepiness Scale (6 versus 2 points; P = 0·001) than rested surgeons. Negative effects of sleep deprivation on reaction time were reversed when caffeine (307 ms versus 299 ms in rested state; P = 0·214) or caffeine plus taurine (326 versus 299 ms; P = 0·110) was administered. Subjective sleepiness was also improved, but not to baseline levels. Sleep deprivation affects laparoscopic psychomotor skills, reaction time and

    This paper reports that experience in the remediation of schools and other large buildings has shown the importance of the effects of both the location of geologic sources and HVAC-induced distribution of indoor radon. In general, elevated radon in areas of schools with evenly distributed HVAC pressures are correlated with maximum soil radon emanations. However, strong or unequal HVAC effects can redistribute indoor radon to areas away from the direct source. Effective remediation required a complete understanding of both contributions. In some schools, highest indoor radon levels were located near large return ducts and were attributed to proximity to negative HVAC pressure. Successful sub-slab depressurization systems were installed, however, in rooms with lower indoor but greatest sub-slab radon levels, closest to the source. This shows the inadequacy of using indoor radon levels alone as a basis for remediation. Wings of two other schools with radon problems have equivalent window fan coil units in rooms of equal size and no central HVAC system. Highest indoor radon levels correlated well with highest sub-slab radon levels due to the equivalent effects of the window units. Diagnostic tests in other schools have revealed: blockwall radon transport to upper floors; high blockwall radon adjacent to sub-slab sources; and elevated indoor radon over crawlspace being drawn upward by HVAC-induced negative pressure, determined from indoor to outdoor micromanometer measurements

    Objective: The aim of the present study was to compare female sexual function between women who underwent conventional abdominal or laparoscopic hysterectomy. Materials and Methods: Seventy-seven women who were scheduled to undergo hysterectomy without oophorectomy for benign gynecologic conditions were included in the study. The women were assigned to laparoscopic or open abdominal hysterectomy according to the surgeons preference. Women with endometriosis and symptomatic prolapsus were excluded. Female sexual function scores were obtained before and six months after the operation from each participant by using validated questionnaires. Results: Pre- and postoperative scores of three different quationnaires were found as comparable in the group that underwent laparoscopic hysterectomy (p>0.05). Scores were also found as comparable in the group that underwent laparotomic hysterectomy (p>0.05). Pre- and postoperative values were compared between the two groups and revealed similar results with regard to all three scores (p>0.05). Conclusion: Our data showed comparable pre- and the postoperative scores for the two different hysterectomy techniques. The two groups were also found to have similar pre- and postoperative score values. PMID:28913149

    The objective of this study was to determine the association of vaginal cuff length (VCL) with vaginal and pelvic recurrence rates in patients with cervical cancer who underwent radical hysterectomies. The clinicopathologic characteristics were collected from the medical records of 280 patients with cervical cancer who underwent radical hysterectomies. The association of VCL with 3-year vaginal and pelvic recurrence rates was determined using a Z-test. The association of VCL with other clinicopathologic characteristics was also determined. The VCL was not associated with 3-year vaginal and pelvic recurrence rates. The 3-year vaginal recurrence rate was 0%-2% and the 3-year pelvic recurrence rate was 7%-8%, independent of VCL. The VCL and the age of patients had an inverse relationship. However, the VCL was not associated with histologic type, FIGO stage, clinical tumor size, tumor size in the surgical specimen, depth of invasion, lymphovascular space invasion, parametrial involvement, lymph node involvement, and adjuvant therapy. One-hundred ninety of 280 patients (68%) underwent adjuvant therapies following radical hysterectomies. Although it is limited by the high rate of adjuvant therapy, the current study suggested that the VCL following radical hysterectomy in patients with cervical cancer was not associated with vaginal and pelvic recurrence rates.

    2016-02-01

    We herein report a case series evaluating the safety and complication rate of transumbilical cord access (TUCA) for pediatric laparoscopic surgery. Data were collected for 556 infants and children. Access into the abdominal cavity was gained via a transverse infraumbilical stab incision passing the fibrotic umbilical cord remnant. Ninety-two infants underwent laparoscopic pyloromyotomy (LPM), 159 female infants underwent herniorrhaphy (LHR) and 309 infants underwent appendectomy (LAP). Of the total operations, 70 % were performed by board-certified surgeons and 30 % were performed by non-board-certified surgeons. The median time of follow-up was 24 months. No cases of acute severe bleeding or organ laceration were noted. TUCA-related complications were observed in nine patients (1.6 %). Omphalitis and persistent wound secretion were detected in eight children and foreign bodies consisting of cyanoacrylate were removed from three of these patients. Meanwhile, umbilical pain leading to surgical revision was observed in one child, and eight umbilical hernias were repaired during the TUCA procedures. No signs of postoperative incisional hernia were recorded. TUCA is a safe and comfortable access method for pediatric laparoscopic surgery in various age groups. This method is easy to learn and can be quickly and safely performed in the vast majority of children.

    2005-12-01

    Full Text Available Background: The aim of this study was to determine if students are suitable candidates to assess the learning effect through a virtual reality laparoscopy simulator (LapSim®. Materials and methods: 14 medical students in their final year without any previous experience with a virtual reality simulator were recruited as subjects. In order to establish a "base line" all subjects were instructed into the "clip application" task - a basis module of the laparoscopy simulator - at the beginning of the study. They were then randomized into two groups. Group A (n=7 had parameter adjusted to an easy level of performance, while group B (n=7 was adjusted to a difficult level. In both levels, errors simulated clinically relevant situations such as vessel rupture and subsequent bleeding. Each participant had to repeat the clip application task ten times consecutively. Results: The mean time for completion ten repetitions was 15 min pro participant in group A and 20 min in group B. From the first to the fifth repetition group A improved significantly the task completion time from 238.9 s to 103.3 s (p<0.007 consecutively and also improved the error score from 312 to 177 (p<0.07. At the tenth repetition they increased the task completion time from 103.3 s to 152.2 s (p<0.09 and increased their error score from 177 to 202 (p=0.25. From the first to the fifth repetition group B also improved the task completion time from 131.6 s to 104.5 s (p<0.31 consecutively and improved the error score from 235 to 208 (p<0.32 but at the tenth repetition they increased the task completion time from 104.5 s to 142.4 s (p<0.45 and clearly increased their error score from 208 to 244 (p<0.38. Conclusion: These results suggest that medical students, who lack clinical background, may be not suitable candidates for assessing the efficiency of a training model using a laparoscopy simulator. If medical students are appointed for such studies, they should receive didactic sessions in

    Full Text Available Abstract Background The management of penetrating abdominal stab wounds has been the subject of continued reappraisal and controversy. In the present study a novel method which combines the use of diagnostic laparoscopy and DPL, termed laparoscopic diagnostic peritoneal lavage (L-DPL is described Method Five trauma patients with penetrating injuries to the lower chest or abdomen were included. Standard videoscopic equipment is utilized for the laparoscopic trauma evaluation of the injured patient. When no significant injury is detected, the videoscope is withdrawn and 1000 mL of normal saline is infused through the abdominal trochar into the peritoneal cavity, and the effluent fluid studied for RBCs, WBC, amylase debry, bile as it is uced in regular diagnostic peritoneal lavage Results Laparoscopic peritoneal lavage (L-DPL was then performed and proved to be negative in all 5 patients. RBC lavage counts above 100,000/mcrl were not considered as a positive lavage result, because the bleeding source was directly observed and controlled laparoscopically. All patients recovered uneventfully and were released within 3 days. This procedure combines the visual advantages of laparoscopy together with the sensitivity and specificty of DPL for the diagnosis of significant penetrating intra-abdominal injury, when the diagnostic strategy of selective consevatism for abdominal stab wounds is adopted. Conclusion A method of laparoscopic diagnostic peritoneal lavage (L-DPL in hemodynamically stable patients with penetrating lower thoracic or abdominal stab wounds is described. The method is especially applicable for trauma surgeons with only basic experience in laparoscopic technique. This procedure is used to obtain conclusive evidence of significant intra-abdominal injury, confirm peritoneal penetration, control intra-abdominal bleeding, and repair lacerations to the diaphragm and abdominal wall. The combination of laparoscopy and DPL afforded by the L

    Full Text Available A 79-year-old female was referred to our Gynecologic Department presenting with a pelvic magnetic resonance imaging (MRI, showing an adnexal mass, later confirmed at the pelvic examination. The patient’s routine laboratory tests were normal. A sonographic examination was performed with inconclusive results. Although the ultrasonography excluded the presence of vascularization and malignant degeneration, the adnexal localization appeared to be dubious. The laparoscopy and the subsequent histologic examination revealed the presence of a mucocele of the appendix. The following case report focuses the attention on a misdiagnosis of appendiceal mucocele. The misdiagnosis caused no negative impact on the treatment that in this case was adequate and successful.

    We aimed to evaluate prognostic significance of preoperatively assessed aspartate aminotransaminase (AST)/alanine aminotransferase (ALT) (De Ritis) ratio on survival in bladder cancer (BC) patients underwent radical cystectomy (RC). We, respectively, analysed clinical and pathological data of 153 patients who underwent RC for BC between February 2006 and December 2016 at a tertiary level hospital. The potential prognostic value of De Ritis ratio was assessed by using ROC curve analysis. The effect of the De Ritis ratio was analysed by the Kaplan-Meier method and Cox regression hazard models for patients' disease-specific survival (DSS) and overall survival (OAS). We had 149 BC patients, in total. Mean age was 61.65 ± 9.13 years. One hundred and thirty-nine (93.3%) of the patients were men. According to ROC analysis, optimal threshold of De Ritis ratio for DSS was 1.30. In Kaplan-Meier analyses, the high De Ritis ratio group showed worse progression in DSS and OAS (all parameters, p < 0.001). On Cox regression models of clinical and pathological parameters to predict DSS, De Ritis ratio (HR 5.79, 95% CI 2.25-15.13), pathological T stage (HR 15.89, 95% CI 3.92-64.33, in all p < 0.001); and to predict OAS, De Ritis ratio (HR 2.61, 95% CI 1.49-4.56; p < 0.001), pathological T stage (HR 5.42, 95% CI 2.63-11.64; p < 0.001) and age (HR 1.05, 95% CI 1.02-1.08; p = 0.001) were determined as independent prognostic factors. Preoperative elevated De Ritis ratio could be an independent prognostic factor in BC patients underwent RC. Our results should be confirmed by large and properly designed prospective, randomized trials.

    Optimal enteral immunonutrition (EIN) regime for gastric cancer (GC) patients underwent gastrectomy remains uncertainty. To assess comparative efficacy of different EIN formulas in GC patients underwent gastrectomy, we performed network meta-analysis. We included 11 RCTs enrolling 840 patients. Pairwise meta-analysis indicated that EIN (RR 0.56, 95% CI 0.36-0.86; MD -0.42, 95% CI -0.74-0.10), Arg+RNA+ω-3-FAs (RR 0.37, 95% CI 0.22-0.63; MD -0.42, 95% CI -0.75-0.07), Arg+Gln+ω-3-FAs (RR 0.22, 95% CI 0.05-0.94; MD -0.69, 95% CI -1.22-1.07) reduced ICs and LOS. Network meta-analysis confirmed the potential of Arg+RNA+ω-3-FAs for ICs (OR 0.27, 95% Crl 0.12-0.49) and Arg+Gln+ω-3-FAs for CIs (OR 0.22, 95% Crl 0.02-0.84) and LOS (SMD -0.63, 95% Crl -1.07-0.13), and indicated that Arg+RNA+ω-3-FAs was superior to Arg+RNA and Arg+Gln for ICs as well. We performed direct and network meta-analyses for randomized controlled trials comparing EIN formulas with each other or standard enteral nutrition (SEN) in reducing infectious complications (ICs), noninfectious complications (NICs) and length of hospital stay (LOS), through January 2016. The surface under the cumulative ranking curve (SCURA) and Grading of Recommendations Assessment, Development and Evaluation (GRADE) were used to rank regimes and rate qualities of evidences respectively. As for GC patients underwent gastrectomy, Arg+RNA+ω-3-FAs and Arg+Gln+ω-3-FAs are the optimal regimes of reducing ICs and LOS.

    Hepatitis A is generally known as a mild, self-limiting disease of the liver, but in rare instances it can progress to fulminant hepatitis, which may require liver transplantation for recovery. Such cases are known to be related to old age and underlying liver disease. We report four cases of hepatitis A in which patients presented with fulminant hepatitis and acute renal failure and underwent liver transplantation. The following common features were observed in our cases: (1) occurrence in relatively old age (>/=39 years old), (2) association with acute renal failure, (3) presence of hepatomegaly, and (4) microscopic features of submassive hepatic necrosis.

    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.

    Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution. This retrospective review evaluates laparoscopic cases performed at Bongolo Hospital between January 2006 and December 2013. Demographic and perioperative information for patients undergoing laparoscopic procedures was collected. Insufflation was achieved using a standard, oil-free air compressor using filtered air and a standard insufflation regulator. A total of 368 laparoscopic procedures were identified within the time period. The majority of cases were gynecologic (43%). There was a 2% (8/368) complication rate with one perioperative death. The 2 complications related to insufflation were episodes of hypotension responsive to standard corrective measures. No intracorporeal combustion events were observed in any cases in which the use of diathermy and room air insufflation were combined. The other complications and the death were unrelated to the use of insufflation with air. Insufflation complications with room air occurred in our study. However, the complications related to insufflation with room air in our study were no different than those described in the literature using carbon dioxide. As room air is less costly than carbon dioxide and readily available, confirming the safety of room air insufflation in prospective studies is warranted. Room air appears to be safe for establishing and maintaining pneumoperitoneum, making laparoscopic surgery more accessible to patients in low-resource settings.

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway.

    Full Text Available Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS. Three main components (naringin, naringenin, and hesperetin were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n=47 and control group (CG, received 20 mg placebo daily, n=48. After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P>0.01. The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

    Malnutrition has been identified as an important predictor of poor clinical outcomes in patients with heart failure. The aim of this study is to examine the prognostic impact of nutritional status in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). The impact of nutrition, assessed using the geriatric nutritional risk index (GNRI) calculated by serum albumin and body mass index, was evaluated in 2,853 patients with CAD who underwent their first PCI between 2000 and 2011. Patients were assigned to tertiles based on their GNRI levels. The incidences of all-cause death and cardiac death were assessed. The median GNRI values were 101 (interquartile range 95 to 106). Lower GNRI levels were associated with older age and higher prevalence of acute coronary syndrome and chronic kidney disease. During the median follow-up period of 7.4 years, Kaplan-Meier curves showed ongoing divergence in rates of mortality among tertiles (GNRI nutritional status was associated with long-term clinical outcomes in CAD patients after PCI. Evaluation of GNRI carries important prognostic information and may guide the therapeutic approach to such patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure.

    Full Text Available Amiodarone is used commonly and effectively in the treatment of arrhythmia; however, it may cause thyrotoxicosis categorized into two types: iodine-induced hyperthyroidism (type 1 amiodarone-induced thyrotoxicosis (AIT and destructive thyroiditis (type 2 AIT. We experienced a case of type 2 AIT, in which high-dose steroid was administered intravenously, and we finally decided to perform total thyroidectomy, resulting in a complete cure of the AIT. Even though steroid had been administered to the patient (maximum 80 mg of prednisolone, the operation was performed safely and no acute adrenal crisis as steroid withdrawal syndrome was found after the operation. Few cases of type 2 AIT that underwent total thyroidectomy with high-dose steroid administration have been reported. The current case suggests that total thyroidectomy should be taken into consideration for patients with AIT who cannot be controlled by medical treatment and even in those under high-dose steroid administration.

    Abstract The prevalence of cognitive impairment and orthostatic hypotension (OH) increases with age, but the results of studies that assessed possible associations between them are inconsistent. The aim of this study is to assess possible associations between cognitive impairment and OH in patients ≥65 years of age who underwent a comprehensive geriatric assessment. A retrospective analysis was conducted of the computerized medical records of the study population from 2005 to 2013. Data collected included blood pressure measurements that enabled the calculation of OH, results of the mini-mental state examination (MMSE), results of the Montreal cognitive assessment (MoCA) test, and cognitive diagnoses that were determined over the course of the assessment. The rate of OH in the study population of 571 adults was 32.1%. The mean MMSE score was 22.5 ± 5.2 among participants with OH and 21.6 ± 5.8 among those without OH (P = 0.09). The absence of a significant association between OH and MMSE remained after adjusting the MMSE score for age and education level. The mean MoCA score was 16.4 ± 5.0 among participants with OH and 16.4 ± 4.8 among those without (P = 0.33). The prevalence of OH was 39% among participants without cognitive impairment, 28.9% among those with mild cognitive impairment (MCI), and 30.6% among those with dementia (P = 0.13). There was no association between OH and cognitive impairment in adults who underwent a comprehensive geriatric assessment. PMID:27442658

    Limited data exist regarding the long-term prognosis of percutaneous coronary intervention (PCI) in young adults. The aim of this study was to retrospectively assess the long-term clinical outcomes in young patients who underwent PCI. Between 1985 and 2011, 7649 consecutive patients underwent PCI, and data from 69 young adults (age ≤40 years) and 4255 old adults (age ≧65 years) were analyzed. A Cox proportional hazards regression analysis was used to determine the independent predictors of a composite endpoint that included all-cause death and acute coronary syndrome (ACS) during the follow-up period. The mean age of the 69 young patients was 36.1±4.9 years, and 96% of them were men. Approximately 30% were current smokers, and their body mass index (BMI) was 26.7±5.0kg/m(2). The prevalence of diabetes and hypertension was 33% and 48%, respectively. All patients had ≥1 conventional cardiovascular risk factor. At a median follow-up of 9.8 years, the overall death rate was 5.8%, and new-onset ACS occurred in 8.7%. Current smoking was an independent predictor of the composite endpoint (hazard ratio 4.46, confidence interval 1.08-19.1, p=0.04) for young adults. Current smoking and obesity (high BMI) are the important clinical characteristics in young Japanese coronary heart disease patients who undergo PCI. The long-term prognosis in young patients is acceptable, but current smoking is a significant independent predictor of death and the recurrence of ACS in young Japanese coronary heart disease patients who are obese.

    Metatarsal head resection is a common and standardized treatment used as part of the surgical routine for metatarsal head osteomyelitis. The aim of this study was to define the influence of the amount of the metatarsal resection on the development of reulceration or ulcer recurrence in patients who suffered from plantar foot ulcer and underwent metatarsal surgery. We conducted a prospective study in 35 patients who underwent metatarsal head resection surgery to treat diabetic foot osteomyelitis with no prior history of foot surgeries, and these patients were included in a prospective follow-up over the course of at least 6 months in order to record reulceration or ulcer recurrences. Anteroposterior plain X-rays were taken before and after surgery. We also measured the portion of the metatarsal head that was removed and classified the patients according the resection rate of metatarsal (RRM) in first and second quartiles. We found statistical differences between the median RRM in patients who had an ulcer recurrence and patients without recurrences (21.48 ± 3.10% vs 28.12 ± 10.8%; P = .016). Seventeen (56.7%) patients were classified in the first quartile of RRM, which had an association with ulcer recurrence (P = .032; odds ratio = 1.41; 95% confidence interval = 1.04-1.92). RRM of less than 25% is associated with the development of a recurrence after surgery in the midterm follow-up, and therefore, planning before surgery is undertaken should be considered to avoid postsurgical complications. © The Author(s) 2015.

    According to current guidelines, in patients without additional risk factors who have undergone aortic valve replacement with a bioprosthesis, anticoagulation in the first 3 months after surgery is still a matter of debate. According to current evidence, aspirin in low doses is a reasonable alternative to vitamin K antagonists (VKA). A comparison is made between the incidence of thrombotic and haemorrhagic complications in patients with low thrombotic risk who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico. The hypothesis: aspirin as monotherapy has a beneficial effect compared to VKA. The studied patients were the low thrombotic risk patients who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico from 2011 to 2015. The groups studied were: aspirin only, VKA only, and the combination of VKA plus aspirin. The patients were retrospectively followed-up for 12 months, and the thrombotic and haemorrhagic complications were documented. Of the 231 patients included in the study, only one patient in the VKA only group presented with a haemorrhagic complication. No thrombotic complications were observed. In the present study no thrombotic complications were observed in patients who did not receive anticoagulation in the first 3 months after an aortic valve replacement with a bioprosthesis after a follow up period of 12 months. This suggests that the use of aspirin only is safe during this period. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

    Full Text Available Autotransplantation of spleen tissue is an attempt for maintenance of splenic functions when splenectomy is indicated in children. It minimizes the risks of overwhelming postsplenectomy infection and it has been done in children with severe portal hypertension due to hepatosplenic mansonic schistosomiasis that underwent splenectomy. The purposes of this investigation were to study the morphology of the residual splenic tissue; to evaluate the residual filtration function of this splenosis; and to assess the immune response to polyvalent pneumococcal vaccine of these patients. Twenty-three children with portal hypertension from mansonic schistosomiasis who underwent splenectomy, ligature of the left gastric vein, autotransplantation of spleen tissue into an omental pouch were evaluated for residual splenic parenchyma and functions. Tc-99m sulfur colloid liver-spleen scans were used for detection of splenic nodules. The search for Howell Jolly bodies were used for assessing the filtration function and Enzyme-linked immunosorbent assay was used for measuring the relative rise in titter of specific pneumococcal antibodies. Splenosis was evident in all children; however, in two there were less than five splenic nodules in the greater omentum, which was considered insufficient. Howell-Jolly bodies were found in the peripheral blood only in these two patients with less evident splenosis. The immune response was adequate in 15 patients; it was intermediate in 4 patients and inadequate in 4 patients. Autotransplantation of spleen tissue into an omental pouch is efficient in maintaining the filtration splenic function in more than 90% of the cases and the immune response to pneumococcal vaccination in approximately 65% of the children.

    Full Text Available Objective: To explore the effect of advanced blood pressure control with nifedipine delayedrelease tablets on the blood pressure in patients underwent nasal endoscope surgery and its feasibility. Methods: A total of 80 patients who were admitted in ENT department from June, 2012 to June, 2015 for nasal endoscope surgery were included in the study and randomized into the observation group and the control group with 40 cases in each group. The patients in the observation group were given nifedipine delayed-release tablets for advanced blood pressure control before operation, and were given routine blood pressure control during operation; while the patients in the control group were only given blood pressure control during operation. The changes of blood pressure, mean central arterial pressure, and heart rate before anesthesia (T0, after intubation (T1, during operation (T2, extubation when waking (T3, 30 min after extubation (T4, and 3 h after back to wards (T5 in the two groups were compared. The intraoperative situation and the surgical field quality in the two groups were compared. Results: SBP, DBP, and MAP levels at T1-5 in the two groups were significantly lower than those at T0. SBP, DBP, and MAP levels at T2 were significantly lower than those at other timing points, and were gradually recovered after operation, but were significantly lower than those at T0. The effect taking time of blood pressure reducing, intraoperative nitroglycerin dosage, and postoperative wound surface exudation amount in the observation group were significantly less than those in the control group. The surgical field quality scores in the observation group were significantly superior to those in the control group. Conclusions: Advanced blood pressure control with nifedipine delayed-release tablets can stabilize the blood pressure during the perioperative period in patients underwent nasal endoscope surgery, and enhance the surgical field qualities.

    High peak airway pressure (Ppeak) and high end-tidal carbon dioxide tension (PETCO2) are the common problems encountered in the obese patients undergoing gynecological laparoscopy with conventional volume-controlled ventilation. This study was designed to investigate whether volume-controlled inverse ratio ventilation (IRV) with inspiratory to expiratory (I:E) ratio of 2:1 could reduce Ppeak or the plateau pressure (Pplat), improve oxygenation, and alleviate lung injury in patients with normal lungs. Sixty obese patients undergoing gynecological laparoscopy were enrolled in this study. After tracheal intubation, the patients were randomly divided into the IRV group (n = 30) and control group (n = 30). They were ventilated with an actual tidal volume of 8 mL/kg, respiratory rate of 12 breaths/min, zero positive end-expiratory pressure and I:E of 1:2 or 2:1. Arterial blood samples, hemodynamic parameters, and respiratory mechanics were recorded before and during pneumoperitoneum. The concentrations of tumor necrosis factor-α, and interleukins 6 and 8 in bronchoalveolar lavage fluid were measured immediately before and 60 minutes after onset of CO2 pneumoperitoneum. IRV significantly increased arterial partial pressure of oxygen, mean airway pressure, and dynamic compliance of respiratory system with concomitant significant decreases in Ppeak and Pplat compared to conventional ventilation with I:E of 1:2 (p laparoscopy without adverse respiratory and hemodynamic effects. It is superior to conventional ratio ventilation in terms of oxygenation, respiratory mechanics and inflammatory cytokine in obese patients undergoing gynecologic laparoscopy. Copyright © 2015.

    Gastric cancer is a leading cause of cancer-related mortality worldwide. We have invented a novel hand-assist device that allows the placement of surgical instruments and the maneuvering of the surgeon's hand, and we have established a new hand-assisted laparoscopic technique called Three United Laparoscopic Surgery (TULS) for laparoscopic dissection of advanced gastric cancer. The present study aimed at exploring the usefulness of TULS in the treatment of advanced gastric cardia cancer. A retrospective study on 100 patients with advanced gastric cardia cancer admitted from January 2014 to June 2015 was done. There were 38 cases of TULS, 30 cases of laparotomy, and 32 cases of laparoscopy-assisted surgery. Statistical comparisons between three treatment groups in operative time, incision length, amount of bleeding, number of lymph nodes dissected, time to flatus after surgery, rate of postoperative complications, hospital stay, and expense were done. For lymph node dissection, there were no significant differences between TULS, laparotomy, and laparoscopy-assisted surgery. However, compared with conventional laparotomy, TULS and laparoscopy-assisted surgery were found to be able to minimize incision length, reduce blood loss during surgery, lower postoperative complication rate, and shorten time to flatus and hospital stay. The differences were statistically significant (P laparoscopy-assisted surgery (P < .05), and it was comparable to that of laparotomy. TULS is as efficient as laparotomy in lymph node dissection, and it shows the advantages of minimally invasive surgery. It can be considered a novel and promising surgical intervention for treatment of advanced gastric cancer.

The LC group had a shorter length of postoperative hospital stay, a lower rate of drainage tube placement, and fewer postoperative complications compared with the OC group, but only the length of postoperative hospital stay showed a significant difference between the two groups (t=7472,P<0.001. The LC group experienced significant reductions in the serum white blood cell count (WBC, C-reactive protein (CRP, interleukin-6 (IL-6, and tumor necrosis factor α (TNFα on days 3 and 5 after surgery (all P<0.05. The OC group experienced significant increases in serum WBC, CRP, IL-6, and TNFα on day 1 after surgery, and significant reductions in these indices on days 3 and 5 after surgery (all P<0.05. The LC group had significantly lower serum WBC, CRP, IL-6, and TNFα on days 1, 3, and 5 after surgery compared with the OC group (all P<0.05. ConclusionLC is safe and effective in the treatment of gangrenous cholecystitis. Compared with OC, LC has the advantages of less trauma and faster

    Full Text Available Introduction: Quality of life can be defined as the expression of aconceptual model that tries to represent patient’s perspectivesand his/her level of satisfaction expressed by numbers. Theobjective of this study is to evaluate the parameters of quality oflife of 23 patients who underwent surgery for anterior cruciateligament reconstruction. Methods: We adopted SF-36, a generichealth-related evaluation questionnaire, to obtain informationregarding several aspects of patients’ health conditions, and theLysholm questionnaire, specific to evaluate the symptoms andfunction of the knee. The questionnaires were applied at two stagesof the treatment: pre- and postoperatively (after the rehabilitationprogram. Results: Before surgery, the Lysholm questionnairepresented the following results: excellent in 4% of the cases, goodin 22%, fair in 22%, and poor in 52%. After surgery (Lysholm e SF-36 the correlation level was approximately 44% (p = 0.041.Discussion: The correlation between the Lysholm and the SF-36questionnaires showed the following: the lower the level of pain,the higher the Lysholm score. The high scores presented by theLysholm questionnaire are directly proportional to physical andemotional aspects, and to functional capacity. Conclusion:Analysis of both questionnaires, as well as of their correlation,showed some improvement in patients´ quality of life. We werealso able to demonstrate the importance and usefulness of applyingthe two questionnaires at three different moments: before, duringand after physiotherapeutic intervention.

    The aim of this study was to determine the effect of anxiety and depression scores of couples who underwent Assisted Reproductive Techniques (ART) on pregnancy outcomes. This study was conducted as a prospective and comparative study with 217 couples. The study data was collected by using a semi-structured questionnaire and the Turkish version of the State-Trait Anxiety Inventory (STAI), and Beck Depression Inventory (BDI). The questionnaire, STAI and BDI were applied to couples who initiated ART treatment. Couples' state anxiety scores were re-evaluated after embryo transfer (ET). A significant relationship was found between the depression score of women and pregnancy outcome (p 0.05) and lower depression scores (p positive pregnancy outcome. Study results indicated that the anxiety and depression scores of couples who had achieved a positive pregnancy result were lower than for couples with a negative result. The results of this study will contribute to the health professionals especially to the nurses who spend the most time with couples in providing consulting services and supporting psychological status of couples during ART process in Turkey.

    Full Text Available Background The current study aimed to evaluate the postural control in patients underwent anterior cruciate ligament reconstruction pre and post wearing functional knee brace. Methods Eighteen athletes undergone unilateral anterior cruciate ligament reconstruction included in the study. They had unilateral anterior cruciate ligament reconstruction at least six months before session test. Postural control was assessed pre and post wearing custom-fit functional knee brace using a posturographic platform prokin 254. The balance tests included: 1 standing on prokin platform with eyes open/closed on anterior cruciate ligament reconstruction limb, 2 standing on prokin platform with eyes open/closed on both limbs. The standard deviation (SD of body sway along the anteroposterior (AP and mediolateral (ML axis, mean velocity of center of pressure (COP along AP/ ML axis and the area ellipse (measured in 2 mm were calculated. Results Results of the paired T-test revealed a significant effect on selected postural control variables for the brace conditions especially in low challengeable conditions (double leg, eyes open test situations (P < 0.05. But in high challengeable conditions this effect was not significant. Conclusions Functional knee brace improved postural control in the simple balancing task in the subjects with anterior cruciate ligament reconstruction. But this improvement in more difficult balancing task was limited.
