2015-01-01

A comparative effectiveness analysis was performed to examine the risks and benefits of laparoscopic bilateral tubal ligation compared with hysteroscopic sterilization using the Essure Permanent Birth Control System (Bayer HealthCare AG, Whippany, NJ). Existing evidence shows that both LBTL and Essure are safe and effective methods of female sterilization. Both have high rates of efficacy and low rates of complications although when complications do occur, those related to the Essure procedure are more likely to be minor in nature. The analysis was limited by the restricted number of studies involving head-to-head comparisons of the 2 approaches. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

Laparoscopic resection of transverse colon carcinoma is technically demanding and was excluded from most of the large trials of laparoscopic colectomy. The aim of this study was to assess the safety, feasibility, and outcome of laparoscopic resection of carcinoma of the transverse colon. A retrospective review was performed to identify patients who underwent laparoscopic resection of transverse colon carcinoma. These patients were compared to patients who had laparoscopic resection for right and sigmoid colon carcinoma. In addition, they were compared to a historical series of patients who underwent open resection for transverse colon cancer. A total of 22 patients underwent laparoscopic resection for transverse colon carcinoma. Sixty-eight patients operated for right colon cancer and 64 operated for sigmoid colon cancer served as comparison groups. Twenty-four patients were identified for the historical open group. Intraoperative complications occurred in 4.5% of patients with transverse colon cancer compared to 5.9% (P = 1.0) and 7.8% (P = 1.0) of patients with right and sigmoid colon cancer, respectively. The early postoperative complication rate was 45, 50 (P = 1.0), and 37.5% (P = 0.22) in the three groups, respectively. Conversion was required in 1 (5%) patient in the laparoscopic transverse colon group. The conversion rate and late complications were not significantly different in the three groups. There was no significant difference in the number of lymph nodes harvested in the laparoscopic and open groups. Operative time was significantly longer in the laparoscopic transverse colectomy group when compared to all other groups (P = 0.001, 0.008, and transverse colectomy, respectively). The results of laparoscopic colon resection for transverse colon carcinoma are comparable to the results of laparoscopic resection of right or sigmoid colon cancer and open resection of transverse colon carcinoma. These results suggest that laparoscopic resection of transverse

Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy. In this review we discuss the indications and the contraindications of laparoscopic splenectomy. Moreover we analyze the standard and modified surgical approaches, and we evaluate the short-term and long-term outcomes. PMID:28979707

To compare the institutional cost of permanent female sterilization by Essure hysteroscopic sterilization and laparoscopic bilateral coagulation. Retrospective cohort study (Canadian Task Force classification II-2). Midwestern academic medical center. Women of reproductive age who elected for permanent contraception by the Essure method (n = 43) or by laparoscopic tubal coagulation (n = 44) during the time frame studied. Placement of the Essure inserts according to the manufacturer's instructions or laparoscopic tubal sterilization using bipolar forceps according to standard techniques of open or closed laparoscopy. Cost-center data for the institutional cost of the procedure was abstracted for each patient included in the study. In addition, demographic data and procedural information were obtained and compared for the patient populations. The Essure system of hysteroscopic sterilization had a significantly decreased cost compared with laparoscopic tubal sterilization when both procedures were performed in an operating room setting. The decrease per patient in institutional cost was 180 dollars (p = .038). This included the cost of the confirmatory hysterosalpingogram 3 months after Essure placement and the cost of laparoscopic tubal occlusion by Filshie clip if the Essure micro-inserts could not be placed. The majority of the cost was related to hospital costs as opposed to physician costs. The Essure procedure had higher costs for disposable equipment (p Essure hysteroscopic sterilization had significant cost savings compared with laparoscopic tubal sterilization (p = .038). We believe that our data represent the minimum of potential savings using this approach, and future developments will only increase the cost difference found in our study.

2014-01-01

The aim of this review was to estimate the incidence of urinary tract injuries associated with laparoscopic hysterectomy and describe the long-term sequelae of these injuries and the impact of early recognition. Studies were identified by searching the PubMed database, spanning the last 10 years. The key words "ureter" or "ureteral" or "urethra" or "urethral" or "bladder" or "urinary tract" and "injury" and "laparoscopy" or "robotic" and "gynecology" were used. Additionally, a separate search was done for "routine cystoscopy" and "gynecology." The inclusion criteria were published articles of original research referring to urologic injuries occurring during either laparoscopic or robotic surgery for gynecologic indications. Only English language articles from the past 10 years were included. Studies with less than 100 patients and no injuries reported were excluded. No robotic series met these criteria. A primary search of the database yielded 104 articles, and secondary cross-reference yielded 6 articles. After reviewing the abstracts, 40 articles met inclusion criteria and were reviewed in their entirety. Of those 40 articles, 3 were excluded because of an inability to extract urinary tract injuries from total injuries. Statistical analysis was performed using a generalized linear mixed effects model. The overall urinary tract injury rate for laparoscopic hysterectomy was 0.73%. The bladder injury rate ranged from 0.05% to 0.66% across procedure types, and the ureteral injury rate ranged from 0.02% to 0.4% across procedure type. In contrast to earlier publications, which cited unacceptably high urinary tract injury rates, laparoscopic hysterectomy appears to be safe regarding the bladder and ureter. Copyright © 2014 AAGL.

Laparoscopic distal pancreatectomy has been shown to be associated with favorable postoperative outcomes using meta-analysis. However, there have been no randomized controlled studies yet. This study aimed to compare laparoscopic and open distal pancreatectomy using propensity score-matching. We retrospectively collected perioperative data of 2,266 patients who underwent distal pancreatectomy in 69 institutes from 2006-2013 in Japan. Among them, 2,010 patients were enrolled in this study and divided into two groups, laparoscopic distal pancreatectomy and open distal pancreatectomy. Perioperative outcomes were compared between the groups using unmatched and propensity matched analysis. After propensity score-matching, laparoscopic distal pancreatectomy was associated with favorable perioperative outcomes compared with open distal pancreatectomy, including higher rate of preservation of spleen and splenic vessels (P pancreatectomy was associated with more favorable perioperative outcomes than open distal pancreatectomy. © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Stormer, Emma J; Sabharwal, Atul J

2009-04-01

To review the exposure pediatric surgery trainees have to laparoscopic surgery in the United Kingdom (UK). A confidential postal questionnaire was sent to all trainees working at registrar level in centers responsible for pediatric surgical training in the UK. Questions assessed the number of consultants with an interest in laparoscopic surgery, types of cases performed laparoscopically, and trainees' role in laparoscopic appendicectomy (LA). Questionnaires were sent to 112 trainees with a 55% response rate (62 replies). At least one response was received from each unit. Based on responses, 49 to 67 consultants in 21 training centers have an interest in laparoscopic surgery (0%-100% of consultants per unit). LA was offered in 20 out of 21 training centers. There was no significant difference in the proportion of appendicectomies performed laparoscopically by junior (years 1-3) and senior (years 4-6) trainees. A significantly higher proportion of junior trainees had not performed any LAs (P = 0.02). Seventy-three percent of trainees were the principal operator. For trainees who were principal operators, the cameraperson was a consultant in 52% and a junior trainee in 17%. The time of day affected the likelihood of a procedure being carried out laparoscopically in 43 (81%) responses. The majority of trainees' exposure to laparoscopic surgery could be viewed as suboptimal; however, the exposure gained varies significantly between different units throughout the UK. In an age moving in favor of minimal access surgery, all units must be in a position to offer pediatric laparoscopic surgical training.

Laparoscopic appendectomy is probably the technique of choice in acute appendicitis. Single port laparoscopic surgery (SILS) has been proposed as an alternative technique. The objective of this study is to compare the safety and efficacy of SILS against conventional laparoscopic appendectomy (LA). From January 2011 to September 2012, 120 patients with acute appendicitis were prospectively randomized; 60 for SILS and 60 for LA. Patients between 15 to 65 years were selected, with onset of symptoms less than 48h. We compared BMI, surgery time, start of oral intake, hospital stay, postoperative pain, pathology and costs. The median age, BMI, sex and time of onset of symptoms to diagnosis were similar. There were no statistically significant differences in the operative time, start of oral intake or hospital stay. There was a significant difference in postoperative pain being higher in SILS (4±1.3) than in LA (3.3±0.5) with a P=.004. Flemonous appendicitis predominated in both groups in a similar percentage. A total of 3 cases with intra-abdominal abscess (SILS 2, LA 1) required readmission and resolved spontaneously with intravenous antibiotic treatment. One case of SILS required assistance by a 5mm trocar in the RLC for drainage placement. The cost was higher in SILS due the single port device. SILS appendectomy is safe, effective and has similar results to LA in selected patients, and although the cost is greater, the long term results will determine the future of this technique.

We conducted a systematic review and meta-analysis to compare the clinical outcomes between laparoscopic splenectomy and the traditional open splenectomy in children. Literature searches were conducted to identify studies having compared the laparoscopic splenectomy (LS) and open splenectomy (OS) for children. Parameters such as operative time, blood loss, length of postoperative stay, the removal of accessory spleens and postoperative complications including postoperative high fever, acute chest syndrome (ACS), and ileus were pooled and compared by meta-analysis. Among the 922 pediatric participants included in the 10 studies, 508 had received LS and 414 OS. There were shorter length of hospital stays, less blood loss, and longer operative times with the LS approach compared with OS. However, no significant difference was found between LS and OS in the secondary outcome, such as the removal of accessory spleens or postoperative complications including postoperative high fever, ACS, and ileus. LS is a feasible, safe, and effective surgical procedure alternative to OS for pediatric patients. Compared with OS, LS has the advantage of shorter hospital stay and less blood loss. Besides, total postoperative complications may be slightly lower in LS. We conclude that LS should be considered an acceptable option for children.

Laparoscopic distal pancreatectomy: Up-to-date and literature review

Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffusion. Additional researches are necessary to determine the best technique to improve the procedure results. PMID:23082049

Robotic assisted laparoscopic pyeloplasty is an emerging, minimally invasive alternative to open pyeloplasty in children for ureteropelvic junction obstruction. The procedure is associated with smaller incisions and shorter hospital stays. To our knowledge previous outcome analyses have not included human capital calculations, especially regarding loss of parental workdays. We compared perioperative factors in patients who underwent robotic assisted laparoscopic and open pyeloplasty at a single institution, especially in regard to human capital changes, in an institutional cost analysis. A total of 44 patients 2 years old or older from a single institution underwent robotic assisted (37) or open (7) pyeloplasty from 2008 to 2010. We retrospectively reviewed the charts to collect demographic and perioperative data. The human capital approach was used to calculate parental productivity losses. Patients who underwent robotic assisted laparoscopic pyeloplasty had a significantly shorter average hospital length of stay (1.6 vs 2.8 days, p human capital gains, eg decreased lost parental wages, and lower hospitalization expenses. Future comparative outcome analyses in children should include financial factors such as human capital loss, which can be especially important for families with young children.

The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

Laparoscopic and vaginal hysterectomies are common gynaecological procedures. Same-day discharge is usual care in various gynaecological procedures like laparoscopic sterilisation and laparoscopic oophorectomies. In major procedures like vaginal or laparoscopic hysterectomy patients are usually admitted overnight. We systematically reviewed the literature to identify complications, risk factors for (re)admittance, financial consequences and patient satisfaction of same-day discharge after a vaginal or laparoscopic hysterectomy. We systematically searched PubMed, UptoDate, Embase, Cochrane and CINAHL database from inception until July 16th 2016. We selected randomized controlled trials, prospective and retrospective cohort studies assessing the safety and feasibility of same-day discharge after vaginal or laparoscopic hysterectomy. The outcome parameters that were assessed were admission rate, re-admission rate, minor and major complications, patient satisfaction and financial consequences. 27 articles were included in the systematic review. All studies provided data about the admission rate and therefore failure of same-day discharge. Eleven prospective studies were included which compromised a total of 2391 hysterectomies. The percentage of overnight admissions was median 9.3% [0-25%]. Eight retrospective studies, which screened their patients before undergoing an outpatient hysterectomy, showed in 1500 subjects a mean admission rate of 10% [4,4-64%]. Four retrospective studies, which considered a large total cohort of 142,799 hysterectomies had a mean admission rate of 59,7% [48-79%]. The overall re-admission rate was low, varying from 0.73-4.0%. Minor complications were reported in respectively 4,3% and 7,3% in prospective respectively retrospective trials. Major complications were described in 0.7%-3.6% of all cases. Generally high satisfaction rates were reported in the observational trials. Same-day discharge after laparoscopic and vaginal hysterectomy seems

Open appendicectomy is the traditional standard treatment for appendicitis. Laparoscopic appendicectomy is perceived as a procedure with greater potential for complications and longer operative times. This paper examines the hypothesis that unsupervised laparoscopic appendicectomy by surgical trainees is a safe and time-effective valid alternative. Medical records, operating theatre records and histopathology reports of all patients undergoing laparoscopic and open appendicectomy over a 15-month period in two hospitals within an area health service were retrospectively reviewed. Data were analysed to compare patient features, pathology findings, operative times, complications, readmissions and mortality between laparoscopic and open groups and between unsupervised surgical trainee operators versus consultant surgeon operators. A total of 143 laparoscopic and 222 open appendicectomies were reviewed. Unsupervised trainees performed 64% of the laparoscopic appendicectomies and 55% of the open appendicectomies. There were no significant differences in complication rates, readmissions, mortality and length of stay between laparoscopic and open appendicectomy groups or between trainee and consultant surgeon operators. Conversion rates (laparoscopic to open approach) were similar for trainees and consultants. Unsupervised senior surgical trainees did not take significantly longer to perform laparoscopic appendicectomy when compared to unsupervised trainee-performed open appendicectomy. Unsupervised laparoscopic appendicectomy by surgical trainees is safe and time-effective.

Single incision laparoscopic liver resection (SILL – a systematic review

Benzing, Christian

2015-12-01

Full Text Available Background: Today, minimally invasive liver resections for both benign and malignant tumors are routinely performed. Recently, some authors have described single incision laparoscopic liver resection (SILL procedures. Since SILL is a relatively young branch of laparoscopy, we performed a systematic review of the current literature to collect data on feasibility, perioperative results and oncological outcome.Methods: A literature research was performed on Medline for all studies that met the eligibility criteria. Titles and abstracts were screened by two authors independently. A study was included for review if consensus was obtained by discussion between the authors on the basis of predefined inclusion criteria. A thorough quality assessment of all included studies was performed. Data were analyzed and tabulated according to predefined outcome measures. Synthesis of the results was achieved by narrative review. Results: A total of 15 eligible studies were identified among which there was one prospective cohort study and one randomized controlled trial comparing SILL to multi incision laparoscopic liver resection (MILL. The rest were retrospective case series with a maximum of 24 patients. All studies demonstrated convincing results with regards to feasibility, morbidity and mortality. The rate of wound complications and incisional hernia was low. The cosmetic results were good.Conclusions: This is the first systematic review on SILL including prospective trials. The results of the existing studies reporting on SILL are favorable. However, a large body of scientific evidence on the field of SILL is missing, further randomized controlled studies are urgently needed.

The focus of research in simulation-based laparoscopic training has changed from examining whether simulation training works to examining how best to implement it. In laparoscopic skills training, portable and affordable box trainers allow for off-site training. Training outside simulation centers and hospitals can increase access to training, but also poses new challenges to implementation. This review aims to guide implementation of off-site training of laparoscopic skills by critically reviewing the existing literature. An iterative systematic search was carried out in MEDLINE, EMBASE, ERIC, Scopus, and PsychINFO, following a scoping review methodology. The included literature was analyzed iteratively using a thematic analysis approach. The study was reported in accordance with the STructured apprOach to the Reporting In healthcare education of Evidence Synthesis statement. From the search, 22 records were identified and included for analysis. A thematic analysis revealed the themes: access to training, protected training time, distribution of training, goal setting and testing, task design, and unsupervised training. The identified themes were based on learning theories including proficiency-based learning, deliberate practice, and self-regulated learning. Methods of instructional design vary widely in off-site training of laparoscopic skills. Implementation can be facilitated by organizing courses and training curricula following sound education theories such as proficiency-based learning and deliberate practice. Directed self-regulated learning has the potential to improve off-site laparoscopic skills training; however, further studies are needed to demonstrate the effect of this type of instructional design.

This present study sought to review the feasibility and patients' satisfaction of laparoscopic cholecystectomy to be perform as daycare procedure. Sixty-two patients with symptomatic gallstones were recruited within a year. They were randomized into overnight stay and daycare groups. The outcomes and post-operative complications were analyzed. Fifty-eight patients were eligible for analysis and four patients were excluded because of conversion to open cholecystectomy. All patients in daycare group reported no fever but two patients in the overnight stay group complaint of post-operative fever (p=0.150). The mean pain score using Visual Analogue Score (VAS) in daycare group was 2.93 but in the overnight stay was recorded as 3.59 (p=0.98). Five patients had post-operative nausea and vomiting (PONV) in daycare group compared to 2 patients in the overnight stay group (p=0.227). Patient's satisfaction were higher in the daycare group (p=0.160). All patients in daycare group were back at work within a week but in overnight stay, 11 patients had to stay off work for more than one week (p=0.01). Daycare laparoscopic cholecystectomy is safe and feasible. The satisfaction of daycare surgery is higher than overnight stay group. Patients' selection is an important aspect of its success.

Colovesical fistulas originating from complicated sigmoid diverticular disease are rare. The primary aim of this review was to evaluate the role of laparoscopic surgery in the treatment of this complication. The secondary aim was to determine the best surgical treatment for this disease. A systematic search was conducted for studies published between 1992 and 2012 in PubMed, the Cochrane Register of Controlled Clinical Trials, Scopus, and Publish or Perish. Studies enrolling adults undergoing fully laparoscopic, laparoscopic-assisted, or hand-assisted laparoscopic surgery for colovesical fistula secondary to complicated sigmoid diverticular disease were considered. Data extracted concerned the surgical technique, intraoperative outcomes, and postoperative outcomes based on the Cochrane Consumers and Communication Review Group's template. Descriptive statistics were reported according to the PRISMA statement. In all, 202 patients from 25 studies were included in this review. The standard treatment was laparoscopic colonic resection and primary anastomosis or temporary colostomy with or without resection of the bladder wall. Operative time ranged from 150 to 321 min. It was not possible to evaluate the conversion rate to open surgery because colovesical fistulas were not distinguished from other types of enteric fistulas in most of the studies. One anastomotic leak after bowel anastomosis was reported. There was zero mortality. Few studies conducted follow-up longer than 12 months. One patient required two reoperations. Laparoscopic treatment of colovesical fistulas secondary to sigmoid diverticular disease appears to be a feasible and safe approach. However, further studies are needed to establish whether laparoscopy is preferable to other surgical approaches.

Laparoscopic resection for transverse colon cancer is a technically challenging procedure that has been excluded from various large randomized controlled trials of which the long-term outcomes still need to be verified. The purpose of this study was to evaluate long-term oncologic outcomes for transverse colon cancer patients undergoing laparoscopic colectomy (LAC) or open colectomy (OC). This retrospective review included patients with transverse colon cancer who received a colectomy between January 2006 and December 2010. Short-term and five-year oncologic outcomes were compared between these groups. A total of 131 patients were analyzed in the final study (LAC, 84 patients; OC, 47 patients). There were no significant differences in age, gender, body mass index, tumor location, operative procedure, or blood loss between groups, but the mean operative time in LAC was significantly longer (LAC, 246.8 minutes vs. OC, 213.8 minutes; P = 0.03). Hospital stay was much shorter for LAC than OC (9.1 days vs. 14.5 days, P transverse colon cancer is feasible and safe with comparable short- and long-term outcomes.

Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

Objective To compare the safety and efficacy of hysteroscopic sterilization with the “Essure” device with laparoscopic sterilization in a large, all-inclusive, state cohort. Design Population based cohort study. Settings Outpatient interventional setting in New York State. Participants Women undergoing interval sterilization procedure, including hysteroscopic sterilization with Essure device and laparoscopic surgery, between 2005 and 2013. Main outcomes measures Safety events within 30 days of procedures; unintended pregnancies and reoperations within one year of procedures. Mixed model accounting for hospital clustering was used to compare 30 day and 1 year outcomes, adjusting for patient characteristics and other confounders. Time to reoperation was evaluated using frailty model for time to event analysis. Results We identified 8048 patients undergoing hysteroscopic sterilization and 44 278 undergoing laparoscopic sterilization between 2005 and 2013 in New York State. There was a significant increase in the use of hysteroscopic procedures during this period, while use of laparoscopic sterilization decreased. Patients undergoing hysteroscopic sterilization were older than those undergoing laparoscopic sterilization and were more likely to have a history of pelvic inflammatory disease (10.3% v 7.2%, P<0.01), major abdominal surgery (9.4% v 7.9%, P<0.01), and cesarean section (23.2% v 15.4%, P<0.01). At one year after surgery, hysteroscopic sterilization was not associated with a higher risk of unintended pregnancy (odds ratio 0.84 (95% CI 0.63 to 1.12)) but was associated with a substantially increased risk of reoperation (odds ratio 10.16 (7.47 to 13.81)) compared with laparoscopic sterilization. Conclusions Patients undergoing hysteroscopic sterilization have a similar risk of unintended pregnancy but a more than 10-fold higher risk of undergoing reoperation compared with patients undergoing laparoscopic sterilization. Benefits and risks of both procedures

Laparoscopic technology is gradually accepted in gastric cancer surgery, whose efficacy has been demonstrated by some clinical researches. Randomized controlled trials (RCT) are considered as the most important evidence to prove clinical outcomes of laparoscopic surgery for gastric cancer. Korean gastric surgeons have made great contributions to RCT in laparoscopic gastric cancer surgery. KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group) is one of the most important forerunner and global leader of clinical trials of gastric cancer treatment. KLASS series clinical trials are attracting global attention because of the significant value of surgical treatment for gastric cancer. The RCTs in Korea involve in many aspects of laparoscopic gastrectomy for gastric cancer, including laparoscopy application in early gastric cancer (KLASS-01, KLASS-03 and KLASS-07), advanced gastric cancer (KLASS-02 and KLASS-06), function-preserving gastrectomy (KLASS-04,KLASS-05) and sentinel node navigation surgery (SENORITA trial). In order to share some informations of these RCTs, we review and prospect some important clinical trials of laparoscopic gastric cancer surgery in Korea. With the experience of Korean gastric surgeons, we can make more progress in our own clinical trials of laparoscopic gastric cancer surgery.

Laparoscopic surgery is considered in the treatment of diverticular fistula for the possible reduction of overall morbidity and complication rate if compared to open surgery. Aim of this review is to assess the possible advantages deriving from a laparoscopic approach in the treatment of diverticular fistulas of the colon. Studies presenting at least 10 adult patients who underwent laparoscopic surgery for sigmoid diverticular fistula were reviewed. Fistula recurrence, reintervention, Hartmann's procedure or proximal diversion, conversion to laparotomy were the outcomes considered. 11 non randomized studies were included. Rates of fistula recurrence (0.8%), early reintervention (30 days) (2%) and need for Hartmann's procedure or proximal diversion (1.4%) did not show significant difference between laparoscopy and open technique. there is still concern about which surgery in complicated diverticulitis should be preferred. Laparoscopic approach has led to less postoperative pain, shorter hospital stay, faster recovery and better cosmetic results. Laparoscopic resection and primary anastomosis is a possible approach to sigmoid fistulas but its advantages in terms of lower mortality rate and postoperative stay after colon resection with primary anastomosis should be interpreted with caution. When there is firm evidence supporting it, it is likely that minimally invasive surgery should become the standard approach for diverticular fistulas, thus achieving adequate exposure and better visualization of the surgical field. The lack of RCTs, the small sample size, the heterogeneity of literature do not allow to draw statistically significant conclusions on the laparoscopic surgery for fistulas despite this approach is considered safe.

The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

This study evaluated the short- and long-term outcomes of laparoscopic colectomy compared with open colectomy for patients with transverse colon cancer by matched-pair analysis. This study enrolled 59 patients who underwent laparoscopic colectomy and compared them with 59 matched patients who underwent open colectomy for transverse colon cancer. The following parameters were matched: clinical stage and type of resection. Both short- and long-term outcomes of laparoscopic colectomy were compared with those of open colectomy. No difference was observed between the two groups in terms of age, gender, ASA score, comorbidity, clinical stage and operative procedures. Regarding short-term outcomes, blood loss, time to first flatus, time to liquid diet and postoperative stay were significantly shorter in the laparoscopy group than in the open group, while operation time was significantly longer in the laparoscopy group than in the open group. Postoperative complication was similar between the two groups. With respect to long-term outcomes, the two groups did not differ significantly in terms of 5-year overall and disease-free survival. In summary, laparoscopic colectomy is a safe and feasible option for selected patients with transverse colon cancer. The short- and long-term outcomes of laparoscopic colectomy are considered to be acceptable.

The aim of this study was to determine the clinical effectiveness and cost-effectiveness of laparoscopic, laparoscopically assisted (hereafter together described as laparoscopic surgery) and hand-assisted laparoscopic surgery (HALS) in comparison with open surgery for the treatment of colorectal cancer. Electronic databases were searched from 2000 to May 2005. A review of economic evaluations was undertaken by the National Institute for Health and Clinical Excellence in 2001. This review was updated from 2000 until July 2005. Data from selected studies were extracted and assessed. Dichotomous outcome data from individual trials were combined using the relative risk method and continuous outcomes were combined using the Mantel-Haenszel weighted mean difference method. Summaries of the results from individual patient data (IPD) meta-analyses were also presented. An economic evaluation was also carried out using a Markov model incorporating the data from the systematic review. The results were first presented as a balance sheet for comparison of the surgical techniques. It was then used to estimate cost-effectiveness measured in terms of incremental cost per life-year gained and incremental cost per quality-adjusted life-year (QALY) for a time horizon up to 25 years. Forty-six reports on 20 studies [19 randomised controlled trials (RCTs) and one IPD meta-analysis] were included in the review of clinical effectiveness. The RCTs were of generally moderate quality with the number of participants varying between 16 and 1082, with 10 having less than 100 participants. The total numbers of trial participants who underwent laparoscopic or open surgery were 2429 and 2139, respectively. A systematic review of four papers suggested that laparoscopic surgery is more costly than open surgery. However, the data they provided on effectiveness was poorer than the evidence from the review of effectiveness. The estimates from the systematic review of clinical effectiveness were

A systematic review of laparoscopic port site hernias in gastrointestinal surgery.

LENUS (Irish Health Repository)

Owens, M

2012-02-01

INTRODUCTION: Port site hernia is an important yet under-recognised complication of laparoscopic surgery, which carries a high risk of strangulation due to the small size of the defect involved. The purpose of this study was to examine the incidence, classification, and pathogenesis of this complication, and to evaluate strategies to prevent and treat it. METHODS: Medline was searched using the words "port site hernia", "laparoscopic port hernia" "laparoscopic complications" and "trocar site hernias". The search was limited to articles on cholecystectomy, colorectal, bariatric or anti-reflux surgery published in English. A total of 42 articles were analysed and of these 35 were deemed eligible for review. Inclusion criteria were laparoscopic gastrointestinal surgery in English only with reported incidence of port site herniation. Studies were excluded if insufficient data was provided. Eligible studies were also cross-referenced. RESULTS: Analysis of 11,699 patients undergoing laparoscopic gastrointestinal procedures demonstrated an incidence of port site hernias of 0.74% with a mean follow-up of 23.9 months. The lowest incidence of port site herniation was for bariatric surgery with 0.57% in 2644 patients with a mean follow-up of 67.4 months while the highest incidence was for laparoscopic colorectal surgery with an incidence of 1.47% in 477 patients with a mean follow-up of 71.5 months. CONCLUSION: All fascial defects larger than or equal to 10mm should be closed with peritoneum, while smaller defects may require closure in certain circumstances to prevent herniation. Laparoscopic port site herniation is a completely preventable cause of morbidity that requires a second surgical procedure to repair.

Alaker, Medhat; Wynn, Greg R; Arulampalam, Tan

2016-05-01

Laparoscopic surgery requires a different and sometimes more complex skill set than does open surgery. Shortened working hours, less training times, and patient safety issues necessitates that these skills need to be acquired outside the operating room. Virtual reality simulation in laparoscopic surgery is a growing field, and many studies have been published to determine its effectiveness. This systematic review and meta-analysis aims to evaluate virtual reality simulation in laparoscopic abdominal surgery in comparison to other simulation models and to no training. A systematic literature search was carried out until January 2014 in full adherence to PRISMA guidelines. All randomised controlled studies comparing virtual reality training to other models of training or to no training were included. Only studies utilizing objective and validated assessment tools were included. Thirty one randomised controlled trials that compare virtual reality training to other models of training or to no training were included. The results of the meta-analysis showed that virtual reality simulation is significantly more effective than video trainers, and at least as good as box trainers. The use of Proficiency-based VR training, under supervision with prompt instructions and feedback, and the use of haptic feedback, has proven to be the most effective way of delivering the virtual reality training. The incorporation of virtual reality training into surgical training curricula is now necessary. A unified platform of training needs to be established. Further studies to assess the impact on patient outcomes and on hospital costs are necessary. (PROSPERO Registration number: CRD42014010030). Copyright © 2016 IJS Publishing Group Ltd.

Hassan, Mohamed E; Al Ali, Khalid

2014-01-01

Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children. The data of children aged splenectomy for hematologic disorders were retrospectively reviewed in 2 pediatric surgery centers from June 2004 until July 2012. The study included 32 patients, 12 who underwent laparoscopic splenectomy versus 20 who underwent open splenectomy. The mean ages were 8.5 years and 8 years in the laparoscopic splenectomy group and open splenectomy group, respectively. The mean operative time was 180 minutes for laparoscopic splenectomy and 120 minutes for open splenectomy. The conversion rate was 8%. The mean amount of intraoperative blood loss was 60 mL in the laparoscopic splenectomy group versus 110 mL in the open splenectomy group. Postoperative atelectasis developed in 2 cases in the open splenectomy group (10%) and 1 case in the laparoscopic splenectomy group (8%). Oral feeding postoperatively resumed at a mean of 7.5 hours in the laparoscopic splenectomy group versus 30 hours in the open splenectomy group. The mean hospital stay was 36 hours in the laparoscopic splenectomy group versus 96 hours in the open splenectomy group. Postoperative pain was less in the laparoscopic splenectomy group. Laparoscopic splenectomy for massive splenomegaly in children is safe and feasible. Although the operative time was significantly greater in the laparoscopic splenectomy group, laparoscopic splenectomy was associated with statistically significantly less pain, less blood loss, better recovery, and shorter hospital stay. Laparoscopic splenectomy for pediatric hematologic disorders should be the gold-standard approach regardless of the size of the spleen.

2001-10-01

Full Text Available Abstract Background The purpose of this clinical study is to evaluate the feasibility of using 2-mm laparoscopic instruments to perform an appendectomy in patients with clinically suspected acute appendicitis and compare the outcome of this mini-laparoscopic or "needlescopic" approach to the conventional laparoscopic appendectomy. Methods Two groups of patients undergoing appendectomy over 24 months were studied. In the first group, needlescopic appendectomy was performed in 15 patients by surgeons specializing in advanced laparoscopy. These patients were compared with the second or control group that included 21 consecutive patients who underwent laparoscopic appendectomy. We compared the patients' demographic data, operative findings, complications, postoperative pain medicine requirements, length of hospital stay, and recovery variables. Differences were considered statistically significant at a p-value Results Patient demographics, history of previous abdominal surgery, and operative findings were similar in both groups. There was no conversion to open appendectomy in either group. No postoperative morbidity or mortality occurred in either group. The needlescopic group had a significantly shorter mean operative time (p = 0.02, reduced postoperative narcotics requirements (p = 0.05, shorter hospital stay (p = 0.04, and quicker return to work (p = 0.03 when compared with the laparoscopic group. Conclusions We conclude that the needlescopic technique is a safe and effective approach to appendectomy. When performed by experienced laparoscopic surgeons, the needlescopic technique results in significantly shorter postoperative convalescence and a prompt recovery.

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.

Laparoscopic Pediatric Inguinal Hernia Repair: Overview of "True Herniotomy" Technique and Review of Current Evidence.

Science.gov (United States)

Feehan, Brendan P; Fromm, David S

2017-05-01

Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis. The laparoscopic repair presents a viable alternative to open repair and offers a number of benefits over the traditional approach. These include superior visualization of the relevant anatomy, ability to assess and repair a contralateral hernia, lower rates of metachronous hernia, shorter operative times in bilateral hernia, and the potential for lower complication rates and improved cosmesis. This is accomplished without increasing recurrence rates or postoperative pain. Further research comparing the different approaches, including standardization of techniques and large randomized controlled trials, will be needed to definitively determine which is superior.

The utilization of robotic platforms for general surgery procedures such as hernia repair is growing rapidly in the United States. A limited amount of data are available evaluating operative outcomes in comparison to standard laparoscopic surgery. We completed a retrospective review comparing robotic and laparoscopic ventral hernia repair to provide safety and outcomes data to help design a future prospective trial design. A retrospective review of 215 patients undergoing ventral hernia repair (142 robotic and 73 laparoscopic) was completed at two large academic centers. Primary outcome measure evaluated was recurrence. Secondary outcomes included incidence of primary fascial closure, and surgical site occurrences. Propensity for treatment match comparison demonstrated that robotic repair was associated with a decreased incidence of recurrence (2.1 versus 4.2%, p robotic repair was associated with increased incidence of primary fascial closure (77.1 versus 66.7%, p robotic repairs were completed on patients with lower body mass index (28.1 ± 3.6 versus 34.2 ± 6.4, p robotic repair was associated with decreased recurrence and surgical site occurrence. However, the differences noted in the patient populations limit the interpretability of these results. As adoption of robotic ventral hernia repair increases, prospective trials need to be designed in order to investigate the efficacy, safety, and cost effectiveness of this evolving technique.

2018-01-01

The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases - underwent open pyelolithotomy. The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon.

Toh, J W T; Lim, R; Keshava, A; Rickard, M J F X

2016-12-01

To determine the incidence of internal hernias after laparoscopic colorectal surgery and evaluate the risk factors and strategies in the management of this serious complication. Two databases (MEDLINE from 1946 and Embase from 1949) were searched to mid-September 2015. The search terms included volvulus or internal hernia and laparoscopic colorectal surgery or colorectal surgery or anterior resection or laparoscopic colectomy. We found 49 and 124 articles on MEDLINE and Embase, respectively, an additional 15 articles were found on reviewing the references. After removal of duplicates, 176 abstracts were reviewed, with 33 full texts reviewed and 15 eligible for qualitative synthesis. The incidence of internal hernia after laparoscopic colorectal surgery is low (0.65%). Thirty-one patients were identified. Five cases were from two prospective studies (5/648, 0.8%), 20 cases were from seven retrospective studies (20/3165, 0.6%) and six patients were from case reports. Of the 31 identified cases, 21 were associated with left-sided resection, four with right sided resection, two with transverse colectomy, one with a subtotal colectomy and in three cases the operation was not specified. The majority of cases (64.3%) were associated with a restorative left sided resection. Nearly all cases occurred within 4 months of surgery. All patients required re-operation and reduction of the internal hernia and 35.7% of cases required a bowel resection. In 52.2% of cases, the mesenteric defect was closed at the second operation and 52.6% of cases were successfully managed laparoscopically. There were three deaths (0.08%). Mesenteric hernias are a rare but important complication of laparoscopic colorectal surgery. The evidence does not support routine closure for all cases, but selective closure of the mesenteric defect during left-sided restorative procedures in high-risk patients at the initial surgery may be considered.

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), pstart of oral tolerance and less surgical wound infection (pstart of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

To estimate readmission rates and emergency care use by patients discharged home the same day after laparoscopic hysterectomy. This was a retrospective case series of patients discharged home the same-day after total or supracervical laparoscopic hysterectomy in a managed care setting. Chart reviews were performed for outcomes of interest which included readmission rates, emergency visits, and surgical and demographic characteristics. The two hysterectomy groups were compared using χ² tests for categorical variables and t tests or Wilcoxon rank-sum tests for continuously measured variables. One-thousand fifteen laparoscopic hysterectomies were performed during the 3-year study period. Fifty-two percent (n=527) of the patients were discharged home the same-day; of those, 46% (n=240) had total laparoscopic hysterectomies and 54% (n=287) had supracervical. Cumulative readmission rates were 0.6%, 3.6%, and 4.0% at 48 hours, 3 months, and 12 months, respectively. The most common readmission diagnoses included abdominal incision infection, cuff dehiscence, and vaginal bleeding. Less than 4% of patients presented for emergency care within 48 or 72 hours, most commonly for nausea or vomiting, pain, and urinary retention. Median uterine weight was 155 g, median blood loss was 70 mL, and median surgical time was 150 minutes. There was no difference in readmission rates or emergency visits for the total compared with the supracervical laparoscopic hysterectomy group. Same-day discharge after laparoscopic hysterectomy is associated with low readmission rates and minimal emergency visits in the immediate postoperative period. Same-day discharge may be a safe option for healthy patients undergoing uncomplicated laparoscopic hysterectomy.

Different types of single-incision laparoscopic surgery (SILS) have become increasingly popular. Although SILS is technically even more challenging than conventional laparoscopy, published data of first clinical series seem to demonstrate the feasibility of these approaches. Various attempts have been made to overcome restrictions due to loss of triangulation in SILS by specially designed SILS-specific instruments. This study involving novices in a dry lab compared task performances between conventional laparoscopic surgery (CLS) and single-port laparoscopic surgery (SPLS) using newly designed pre-bent instruments. In this study, 90 medical students without previous experience in laparoscopic techniques were randomly assigned to undergo one of three procedures: CLS, SPLS using two pre-bent instruments (SPLS-pp), or SPLS using one pre-bent and one straight laparoscopic instrument (SPLS-ps). In the dry lab, the participants performed four typical laparoscopic tasks of increasing difficulty. Evaluation included performance times or number of completed tasks within a given time frame. All performances were videotaped and evaluated for unsuccessful attempts and unwanted interactions of instruments. Using subjective questionnaires, the participants rated difficulties with two-dimensional vision and coordination of instruments. Task performances were significantly better in the CLS group than in either SPLS group. The SPLS-ps group showed a tendency toward better performances than the SPLS-pp group, but the difference was not significant. Video sequences and participants` questionnaires showed instrument interaction as the major problem in the single-incision surgery groups. Although SILS is feasible, as shown in clinical series published by laparoscopically experienced experts, SILS techniques are demanding due to restrictions that come with the loss of triangulation. These can be compensated only partially by currently available SILS-designed instruments. The future of

Full Text Available CONTEXT AND PURPOSE: Partial nephrectomy has become the standard of care for renal tumors less than 4 cm in diameter. Controversy still exists, however, regarding the best surgical approach, especially when minimally invasive techniques are taken into account. Robotic-assisted laparoscopic partial nephrectomy (RALPN has emerged as a promising technique that helps surgeons achieve the standards of open partial nephrectomy care while offering a minimally invasive approach. The objective of the present study was to describe our initial experience with robotic-assisted laparoscopic partial nephrectomy and extensively review the pertinent literature. MATERIALS AND METHODS: Between August 2009 and February 2010, eight consecutive selected patients with contrast enhancing renal masses observed by CT were submitted to RALPN in a private institution. In addition, we collected information on the patients' demographics, preoperative tumor characteristics and detailed operative, postoperative and pathological data. In addition, a PubMed search was performed to provide an extensive review of the robotic-assisted laparoscopic partial nephrectomy literature. RESULTS: Seven patients had RALPN on the left or right sides with no intraoperative complications. One patient was electively converted to a robotic-assisted radical nephrectomy. The operative time ranged from 120 to 300 min, estimated blood loss (EBL ranged from 75 to 400 mL and, in five cases, the warm ischemia time (WIT ranged from 18 to 32 min. Two patients did not require any clamping. Overall, no transfusions were necessary, and there were no intraoperative complications or adverse postoperative clinical events. All margins were negative, and all patients were disease-free at the 6-month follow-up. CONCLUSIONS: Robotic-assisted laparoscopic partial nephrectomy is a feasible and safe approach to small renal cortical masses.Further prospective studies are needed to compare open partial nephrectomy with

To compare the renal function preservation between laparoscopic radio frequency ablation assisted tumor enucleation and laparoscopic partial nephrectomy. Data were analyzed from 246 patients who underwent laparoscopic radio frequency ablation assisted tumor enucleation and laparoscopic partial nephrectomy for solitary cT1a renal cell carcinoma from January 2013 to July 2015. To reduce the intergroup difference, we used a 1:1 propensity matching analysis. The functional renal parenchyma volume preservation were measured preoperative and 12 months after surgery. The total renal function recovery and spilt GFR was compared. Multivariable logistic analysis was used for predictive factors for renal function decline. After 1:1 propensity matching, each group including 100 patients. Patients in the laparoscopic radio frequency ablation assisted tumor enucleation had a smaller decrease in estimate glomerular filtration rate at 1 day (-7.88 vs -20.01%, p renal parenchyma volume preservation (89.19 vs 84.27%, p renal parenchyma volume preservation, warm ischemia time and baseline renal function were the important independent factors in determining long-term functional recovery. The laparoscopic radio frequency ablation assisted tumor enucleation technology has unique advantage and potential in preserving renal parenchyma without ischemia damage compared to conventional laparoscopic partial nephrectomy, and had a better outcome, thus we recommend this technique in selected T1a patients.

To assess and compare pregnancy outcomes in hydrosalpinx (HX) patients treated by Essure, laparoscopic salpingectomy, and proximal tubal occlusion (LPTO) before IVF. Systematic review and meta-analysis. University-affiliated teaching hospital. Women undergoing Essure, laparoscopic salpingectomy, and LPTO for HX before IVF. The overall combined risk estimates were calculated by means of fixed- or random-effects models. Clinical pregnancy rate (CPR) and live birth rate (LBR). In total, 3,065 patients were included in 33 studies. Thirteen of them were comparative studies among 3 surgical methods and no intervention. In the analysis of comparative studies, there were no significant differences in implantation rate (IR), CPR, and ongoing pregnancy rate/LBR between salpingectomy and LPTO groups. The CPR, IR, and LBR of Essure were significantly lower than those of the laparoscopic surgery (salpingectomy and LPTO) group, with a CPR of 34.1% vs. 44.0% (relative risk [RR] 0.71; 95% confidence interval [CI] [0.51, 0.98]), an IR of 17.3% vs. 38.0% (RR 0.45; 95% CI [0.27, 0.74]), and an LBR of 22.2% vs. 37.4% (RR 0.57; 95% CI [0.35, 0.91]). Management of HX by laparoscopic salpingectomy and LPTO yielded the same effect on the improvement of the pregnancy outcome after IVF. The hysteroscopic placement of Essure devices to treat HX before IVF produces inferior pregnancy outcomes compared with those following the laparoscopic approach. More multicenter randomized, controlled trials are warranted in future research to further examine the conclusion from this meta-analysis. Copyright © 2017 American Society for Reproductive Medicine.

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

Colorectal cancer is the second most common cause of death from neoplastic disease in men and third in women of all ages. Globally, life expectancy is increasing, and consequently, an increasing number of operations are being performed on more elderly patients with the trend set to continue. Elderly patients are more likely to have cardiovascular and pulmonary comorbidities that are associated with increased peri-operative risk. They further tend to present with more locally advanced disease, more likely to obstruct or have disseminated disease. The aim of this review was to investigate the feasibility of laparoscopic colorectal resection in very elderly patients, and whether there are benefits over open surgery for colorectal cancer. A systematic literature search was performed on Medline, Pubmed, Embase and Google Scholar. All comparative studies evaluating patients undergoing laparoscopic versus open surgery for colorectal cancer in the patients population over 85 were included. The primary outcomes were 30-day mortality and 30-day overall morbidity. Secondary outcomes were operating time, time to oral diet, number of retrieved lymph nodes, blood loss and 5-year survival. The search provided 1507 citations. Sixty-nine articles were retrieved for full text analysis, and only six retrospective studies met the inclusion criteria. Overall mortality for elective laparoscopic resection was 2.92% and morbidity 23%. No single study showed a significant difference between laparoscopic and open surgery for morbidity or mortality, but pooled data analysis demonstrated reduced morbidity in the laparoscopic group (p = 0.032). Patients undergoing laparoscopic surgery are more likely to have a shorter hospital stay and a shorter time to oral diet. Elective laparoscopic resection for colorectal cancer in the over 85 age group is feasible and safe and offers similar advantages over open surgery to those demonstrated in patients of younger ages.

The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

Full Text Available OBJECTIVES: As the advancements, modifications and standardization of laparoscopy are taking place, there is a need for the reduction in morbidity associated with laparoscopic live donor nephrectomy. This study was performed to determine and reconfirm the advantages of laparoscopic donor nephrectomy over its open counterpart. MATERIALS AND METHODS: Two hundred open live donor nephrectomy (ODN cases were compared to 264 cases of laparoscopic live donor nephrectomy (LDN. Pretransplant functional and radiological evaluation was done routinely by excretory urogram and renal arteriography. In case of vascular variations, CT angiography was preferred. Open cases were done by conventional method and laparoscopic group underwent certain technical and surgical modifications, including meticulous planning for the port placement. Operative time, analgesia requirement, start of the orals, hospital stay, blood loss, late allograft function, incidence of rejection, complications and technical problems were analyzed. RESULTS: Operative time was 135.8 ± 43 and 165 ± 44.4 min ( P < 0.0001, requirement of analgesia was 60.5 ± 40 and 320 ± 120 mg ( P < 0.0001, hospital stay was 4 ± 0.04 and 5.7 ± 2.03 days ( P < 0.0001, warm ischemia time was 6.1 ± 2.0 and 4.1 ± 0.80 min ( P < 0.0001 and time taken for the serum creatinine to stabilize in the recipient was 4.1 ± 1.6 and 4.32 ± 1.40 days ( P =0.06 for LDN and ODN groups respectively. There was a significant reduction in the blood loss in LDN group ( P =0.0005. Overall complications were 6.81 and 14.5% and ureteric injury was seen in 0.37 and 1% in LDN and ODN respectively. CONCLUSION: Laparoscopic live donor nephrectomy can now be performed with low morbidity and mortality to both donors and recipients and is proving to be the preferred operation to open donor nephrectomy. Our continued innovations in technical modifications have made this novel operation successful.

Laparoscopic liver resection has progressively gained acceptance as a safe and effective procedure in the treatment of benign and malignant liver neoplasms. However, blood loss remains the major challenge in liver surgery. Several techniques and devices have been introduced in liver surgery in order to minimize intraoperative haemorrhage during parenchymal transection. Radiofrequency (RF)-assisted liver resection has been shown to be an effective method to minimize bleeding in open and laparoscopic liver resection. A number of RF devices for parenchymal transection have been designed to assist laparoscopic liver resections. Here we have reviewed the results of various RF devices in laparoscopic liver resection. A total 15 article were considered relevant for the evaluation of technical aspects and outcomes of RF-assisted liver resections in laparoscopic procedures. In these studies, 176 patients had laparoscopic liver resection using RF-assisted parenchymal coagulation. Two monopolar and three bipolar devices were employed. Blood loss was limited in most of the studies. The need of blood transfusions was limited to two cases in all the series. Conversion was necessary due to bleeding in 3 cases. Operative and transection times varied between studies. However, RF-assisted resection with bipolar devices appeared to have taken less time in comparison to other RF devices. RF-related complications were minimum, and only one case of in-hospital death due to hepatic failure was reported. Although RF has been used in a small minority of laparoscopic liver resections, laparoscopic RF-assisted liver resection for benign and malignant disease is a safe and feasible procedure associated with reduction in blood loss, low morbidity, and lower hospital mortality rates.

Laparoscopic subtotal colectomy (STC) is a complex procedure. It is possible that short-term benefits for segmental resections cannot be attributed to this complex procedure. This study aims to assess differences in short-term results for laparoscopic versus open STC during a 15-year single-institute experience. We reviewed consecutive patients undergoing laparoscopic or open elective or subacute STC from January 1997 to December 2012. Fifty-six laparoscopic and 50 open STCs were performed. The operation time was significantly longer in the laparoscopic group, median 266 min (range 121-420 min), compared to 153 min (range 90-408 min) in the open group (p < 0.001). Median hospital stay showed no statistical difference, 14 days (range 1-129 days) in the laparoscopic and 13 days (range 1-85 days) in the open group. Between-group postoperative complications were not statistically different. Laparoscopic STC has short-term results similar to the open procedure, except for a longer operation time. The laparoscopic approach for STC is therefore only advisable in selected patients combined with extensive preoperative counseling. Copyright © 2013 S. Karger AG, Basel.

The aim of this study was to compare skills sets during a hand-assisted and straight laparoscopic colectomy on an augmented reality simulator. Twenty-nine surgeons, assigned randomly in 2 groups, performed laparoscopic sigmoid colectomies on a simulator: group A (n = 15) performed hand-assisted then straight procedures; group B (n = 14) performed straight then hand-assisted procedures. Groups were compared according to prior laparoscopic colorectal experience, performance (time, instrument path length, and instrument velocity changes), technical skills, and operative error. Prior laparoscopic colorectal experience was similar in both groups. Both groups had better performances with the hand-assisted approach, although technical skill scores were similar between approaches. The error rate was higher with the hand-assisted approach in group A, but similar between both approaches in group B. These data define the metrics of performance for hand-assisted and straight laparoscopic colectomy on an augmented reality simulator. The improved scores with the hand-assisted approach suggest that with this simulator a hand-assisted model may be technically easier to perform, although it is associated with increased intraoperative errors.

Mature cystic teratomas, often referred to as dermoid cysts, are the most common germ cell tumors of the ovary in the recent years, transvaginal sonographic diagnosis of ovarian dermoid cysts together with the laparascopic approach have greatly improved the treatment of this benign lesion. We retrospectively reviewed the outcome of laparoscopic surgery for suspected ovarian dermoid cysts. The preoperative findings, operative techniques, and postoperative complications were retrospectively reviewed in the women who underwent lpaparoscopic surgey for dermoid cysts, between January 2001 and May 2003. In 47 women aged 21 to 53 years (median, 38.8 years), 93.6% had a unilateral cyst with a diameter of 17 to 108 mm (median 51 mm). Clinical presentations were pain (62%), abnormal vaginal bleeding (21%) and ovarian torsion (2%), while 17%were diagnosed incidently during routine examination. Surgery included cystectomy (57%), total (36%) or partial oophorectomy (6.4%) and laparoscopic assisted vaginal hysterectomy with bilateral salpingo-oophorectomy (2%). During the cyst extraction, minimal spillage occured in 42.5% of the casesand none developed chemical peritonitis. In 2 patients, conversion to laparotomy (4.3%) was required, one for sigmoid colon, injury and one for malignent ovarian tumor detected via frozen section. The median operating time was 80 minutes (range, 35-180 minutes). Using strict afherence to guidelines for preoperative clinical assessment and intraoperative management, laparoscopic treatment of dermoid cysts appers to be a safe procedure. (author)

The role of laparoscopic surgery in treatment of patients with diverticulitis is unclear. A retrospective comparison of laparoscopic with conventional surgery for patients with chronic diverticulitis was performed to assess morbidity, recovery from surgery, and cost. Records of patients undergoing elective resection for uncomplicated diverticulitis from 1992 to 1994 at a single institution were reviewed. Laparoscopic resection involved complete intracorporeal dissection, bowel division, and anastomosis with extracorporeal placement of an anvil. Sigmoid and left colon resections were performed laparoscopically in 25 patients and by open technique in 17 patients by two independent operating teams. No significant differences existed in age, gender, weight, comorbidities, or operations performed. In the laparoscopic group, three operations were converted to open laparotomy (12 percent) because of unclear anatomy. Major complications occurred in two patients who underwent laparoscopic resection, both requiring laparotomy, and in one patient in the conventional surgery group who underwent computed tomographic-guided drainage of an abscess. Patients who underwent laparoscopic resection tolerated a regular diet sooner than patients who underwent conventional surgery (3.2 +/- 0.9 vs. 5.7 +/- 1.1 days; P < 0.001) and were discharged from the hospital earlier (4.2 +/- 1.1 vs. 6.8 +/- 1.1 days; P < 0.001). Overall costs were higher in the laparoscopic group than the open surgery group ($10,230 +/- 49.1 vs. $7,068 +/- 37.1; P < 0.001) because of a significantly longer total operating room time (397 +/- 9.1 vs. 115 +/- 5.1 min; P < 0.001). Follow-up studies with a mean of one year revealed two port site infections in the laparoscopic group and one wound infection in the open group. Of patients undergoing conventional resection, one patient experienced a postoperative bowel obstruction that was managed nonoperatively, and, in one patient, an incarcerated incisional hernia

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

Recently, there has been a growth in studies supporting the hypothesis that video games have positive effects on basic laparoscopic skills. This review discusses all studies directly related to these effects. A search in the PubMed and EMBASE databases was performed using synonymous terms for video games and laparoscopy. All available articles concerning video games and their effects on skills on any laparoscopic simulator (box trainer, virtual reality, and animal models) were selected. Video game experience has been related to higher baseline laparoscopic skills in different studies. There is currently, however, no standardized method to assess video game experience, making it difficult to compare these studies. Several controlled experiments have, nevertheless, shown that video games cannot only be used to improve laparoscopic basic skills in surgical novices, but are also used as a temporary warming-up before laparoscopic surgery.

PROCEDURES Medical records of female dogs that underwent laparoscopic sterilization between 2003 and 2013 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of the surgical procedure, durations of anesthesia and surgery, intraoperative and immediate postoperative (ie, during hospitalization) complications, and short- (≤ 14 days after surgery) and long-term (> 14 days after surgery) outcomes were recorded. Data for patients undergoing LapOVE versus LapOVH were compared. RESULTS Intraoperative and immediate postoperative complications were infrequent, and incidence did not differ between groups. Duration of surgery for LapOVE was significantly less than that for LapOVH; however, potential confounders were not assessed. Surgical site infection was identified in 3 of 224 (1.3%) dogs. At the time of long-term follow-up, postoperative urinary incontinence was reported in 7 of 125 (5.6%) dogs that underwent LapOVE and 12 of 82 (14.6%) dogs that underwent LapOVH. None of the dogs had reportedly developed estrus or pyometra by the time of final follow-up. Overall, 205 of 207 (99%) owners were satisfied with the surgery, and 196 of 207 (95%) would consider laparoscopic sterilization for their dogs in the future. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that short- and long-term outcomes were similar for female dogs undergoing sterilization by means of LapOVE or LapOVH; however, surgery time may have been shorter for dogs that underwent LapOVE. Most owners were satisfied with the outcome of laparoscopic sterilization.

Laparoscopic splenectomy is considered the gold standard for resecting normal-to-moderately bigger spleens in benign conditions, and in addition could be tried for patients with malignant splenic disorders. However, the safety of laparoscopic splenectomy in patients with hypersplenism is not well-known. This study aimed to investigate the efficacy and safety of laparoscopic splenectomy for patients with hypersplenism secondary to liver cirrhosis by comparing with the open splenectomy. Several databases were searched to identify comparative studies fulfilling the predefined selection criteria from January 2000 to June 2015. The subsequent key words were utilized for browsing "laparoscopy" or "laparoscopic", "open", "splenectomy", and "liver cirrhosis". Studies evaluating laparoscopic and open splenectomy for patients with liver cirrhosis were incorporated. Two evaluators personally strained the title and abstract of each publication. Citations with contemplated compliance within our eligibility criteria underwent compressed review. Meta-analysis was carried out according to the recommendations of the Cochrane Collaboration software (review manager 5.1). Seven studies containing 509 patients were included. Compared with the open splenectomy group, patients in the laparoscopic splenectomy group had significantly less intraoperative blood loss (MD=210.30; 95% CI: 11.28-409.32; P=0.04), longer operative time (MD=-31.58; 95% CI: -53.34--9.82; P=0.004), shorter duration of postoperative hospital stay (MD=3.41; 95% CI: 2.39-4.43; Psplenectomy.

Maintenance of optimal vision during minimally invasive surgery is crucial to maintaining operative awareness, efficiency, and safety. Hampered vision is commonly caused by laparoscopic lens fogging (LLF), which has prompted the development of various antifogging fluids and warming devices. However, limited comparative evidence exists in contemporary literature. Despite technologic advancements there remains no consensus as to superior methods to prevent LLF or restore visual acuity once LLF has occurred. We performed a review of literature to present the current body of evidence supporting the use of numerous techniques. A standardized Preferred Reporting Items for Systematic Reviews and Meta-Analysis review was performed, and PubMed, Embase, Web of Science, and Google Scholar were searched. Articles pertaining to mechanisms and prevention of LLF were reviewed. We applied no limit to year of publication or publication type and all articles encountered were included in final review. Limited original research and heterogenous outcome measures precluded meta-analytical assessment. Vision loss has a multitude of causes and although scientific theory can be applied to in vivo environments, no authors have completely characterized this complex problem. No method to prevent or correct LLF was identified as superior to others and comparative evidence is minimal. Robotic LLF was poorly investigated and aside from a single analysis has not been directly compared to standard laparoscopic fogging in any capacity. Obscured vision during surgery is hazardous and typically caused by LLF. The etiology of LLF despite application of scientific theory is yet to be definitively proven in the in vivo environment. Common methods of prevention of LLF or restoration of vision due to LLF have little evidence-based data to support their use. A multiarm comparative in vivo analysis is required to formally assess these commonly used techniques in both standard and robotic laparoscopes.

The long-term oncologic stability of laparoscopic surgery for colon cancer was established, and laparoscopic surgery was accepted as an alternative to conventional open surgery for colon cancer. However, transverse colon cancer was excluded from the majority of the previous prospective studies. As a result, debate on laparoscopic surgery for transverse colon cancer continues. This study aimed to compare the clinicopathologic outcome of laparoscopic surgery with that of conventional open surgery for transverse colon cancer. From August 2004 to December 2007, 106 cases of transverse colon cancer were managed by resection at our institution, and 89 of these cases were included in this study. Age, sex, body mass index (BMI), operation time, blood loss, time to first flatus, time to start of diet, hospital stay, complications, tumor size, distal resection margin, proximal resection margin, and number of nodes harvested were compared between the two groups. No significant differences were found between the laparoscopic and conventional groups in terms of age, sex, BMI, operation time, or hospital stay. The mean blood loss during the operations was significantly less in the laparoscopic group (113.8 +/- 128.9 ml) than in the conventional group (278.8 +/- 268.7 ml; p transverse colon cancer, and the oncologic quality of laparoscopic surgery was found to be acceptable compared with conventional open surgery.

To report our experience with solo-surgeon, single-port laparoscopic anterior resection (solo SPAR) for sigmoid colon cancer. Data from sigmoid colon cancer patients who underwent anterior resections (ARs) using the single-port, solo surgery technique (n = 31) or the conventional single-port laparoscopic technique (n = 45), between January 2011 and July 2016, were retrospectively analyzed. In the solo surgeries, making the transumbilical incision into the peritoneal cavity was facilitated through the use of a self-retaining retractor system. After establishing a single port through the umbilicus, an adjustable mechanical camera holder replaced the human scope assistant. Patient and tumor characteristics and operative, pathologic, and postoperative outcomes were compared. The operative times and estimated blood losses were similar for the patients in both treatment groups. In addition, most of the postoperative variables were comparable between the two groups, including postoperative complications and hospital stays. In the solo SPAR group, comparable lymph nodes were attained, and sufficient proximal and distal cut margins were obtained. The difference in the proximal cut margin significantly favored the solo SPAR, compared with the conventional AR group (P = .000). This study shows that solo SPAR, using a passive camera system, is safe and feasible for use in sigmoid colon cancer surgery, if performed by an experienced laparoscopic surgeon. In addition to reducing the need for a surgical assistant, the oncologic requirements, including adequate margins and sufficient lymph node harvesting, could be fulfilled. Further evaluations, including prospective randomized studies, are warranted.

Short gastric vessels are divided during the laparoscopic Nissen fundoplication resulting in splenic infarct in some cases. We report a case of laparoscopic floppy Nissen fundoplication with splenic infarct that was recognized during the procedure and provide a brief literature review. The patient underwent a laparoscopic floppy Nissen fundoplication. We observed a partial infarction of the spleen. She reported no pain. A follow-up computed tomography scan showed an infarct, and a 3-month abdominal ultrasound showed complete resolution. Peripheral splenic arterial branches have very little collateral circulation. When these vessels are occluded or injured, an area of infarction will occur immediately. Management strategies included a trial of conservative management and splenectomy for persistent symptoms or complications resulting from splenic infarct. In conclusion, we believe that the real incidence is probably much higher because many cases of SI may have gone undiagnosed during or following an operation, because some patients are asymptomatic. We propose to check spleen carefully for the possibility of splenic infarct. PMID:24833155

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

Laparoscopic total mesorectal excision (TME) remains a technically challenging procedure. This study aims to compare the surgical outcomes of the robotic-assisted laparoscopic (RAL) versus hand-assisted laparoscopic (HAL) techniques in performing TME for patients with rectal cancers. A retrospective review of all patients who underwent RAL TME for rectal cancers was performed. These cases were matched for age, sex, and stage of malignancy with patients who underwent HAL TME. Data collected included age, sex, American Society of Anesthesiologists scores, comorbid conditions, types of surgical resections and operative times, perioperative complications, length of hospital stays, and histopathologic outcomes were analyzed. From August 2008 to August 2011, 19 patients, with a median age of 62 (range, 47 to 92) years underwent RAL TME. Eight (42.1%) patients received neoadjuvant chemoradiotherapy. The median docking and operative times were 10 (range, 3 to 34) and 390 (range, 289 to 771) minutes, respectively. There was 1 (5.3%) conversion to open surgery. The grade of mesorectal excision was histopathologically reported as complete in all 19 cases. Positive circumferential margin was reported in 1 (5.3%) patient.Comparing the 2 groups, more patients in the RAL group received neoadjuvant chemoradiotherapy (8 vs. 3; P=0.048). The operative times were longer in the RAL group (390 vs. 225 min; P<0.001). A higher proportion of patients in the HAL group required conversion to open surgery (5 vs. 1; P=0.180) and developed perioperative morbidities (3 vs. 7; P=0.269). The median length of hospitalization was comparable between both groups (RAL: 7 vs. HAL: 6 d; P=0.476).The procedural cost was significantly higher in the RAL group (US$12,460 vs. US$8560; P<0.001), whereas the nonprocedural cost remained comparable between the 2 groups (RAL: US$4470 vs. HAL: US$4500; P=0.729). RAL TME is associated with lower conversion and morbidity rates compared with HAL TME. The longer

To determine the best operation technique, open versus laparoscopic, for insertion of a peritoneal dialysis (PD) catheter with regard to clinical success. Clinical success was defined as an adequate function of the catheter 2 - 4 weeks after insertion. All patients with end-stage renal disease who were suitable for PD and gave informed consent were randomized for either open surgery or laparoscopic surgery. A previous laparotomy was not considered an exclusion criterion. Laparoscopic placement had the advantage of pre-peritoneal tunneling, the possibility for adhesiolysis, and placement of the catheter under direct vision. Catheter fixation techniques, omentopexy, or other adjunct procedures were not performed. Other measured parameters were in-hospital morbidity and mortality and post-operative infections. Between 2010 and 2016, 95 patients were randomized to this study protocol. After exclusion of 5 patients for various reasons, 44 patients received an open procedure and 46 patients a laparoscopic procedure. Gender, age, body mass index (BMI), hypertension, current hemodialysis, severe heart failure, and previous an abdominal operation were not significantly different between the groups. However, in the open surgery group, fewer patients had a previous median laparotomy compared with the laparoscopic group (6 vs 16 patients; p = 0.027). There was no statistically significant difference in mean operation time (36 ± 24 vs 38 ± 15 minutes) and hospital stay (2.1 ± 2.7 vs 3.1 ± 7.3 days) between the groups. In the open surgery group 77% of the patients had an adequate functioning catheter 2 - 4 weeks after insertion compared with 70% of patients in the laparoscopic group ( p = not significant [NS]). In the open surgery group there was 1 post-operative death (2%) compared with none in the laparoscopic group ( p = NS). The morbidity in both groups was low and not significantly different. In the open surgery group, 2 patients had an exit-site infection and 1 patient

Laparoscopic inguinal hernia repair has become a valid option for repair of an inguinal hernia. Due to there are several types of mesh fixation for laparoscopic repair of inguinal hernia. The study aims to assess and compare the efficacy of different types of mesh fixation for laparoscopic repair of inguinal hernia using network meta-analysis. We will systematically search PubMed, EMBASE the Cochrane library, and Chinese Biomedical Literature Database from their inception to March 2018. Randomized controlled trials (RCTs) that compared the effect of different types of mesh fixation for laparoscopic inguinal hernia repair will be included. The primary outcomes are chronic groin pain, incidence risk of hernia recurrence, and complications. Risk of bias assessment of the included RCTs will be conducted using to Cochrane risk of bias tool. A network meta-analysis will be performed using WinBUGS 1.4.3 software and the result figures will be generated using R x64 3.1.2 software and STATA V.12.0 software. Grading of Recommendations Assessment, Development and Evaluation (GRADE) will be used to assess the quality of evidence. The results of this study will be published in a peer-reviewed journal. Our study will generate evidence of laparoscopic repair of mesh fixation for adult patients with inguinal hernia and provide suggestions for clinical practice or guideline.

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

A recent Cochrane review compared laparoscopic versus open distal pancreatectomy for people with for cancers of the body and tail of the pancreas and found that laparoscopic distal pancreatectomy may reduce the length of hospital stay. We compared the cost-effectiveness of laparoscopic distal pancreatectomy versus open distal pancreatectomy for pancreatic cancer. 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. A time horizon of 5 years was used. One-way and probabilistic sensitivity analyses were undertaken. The probabilistic sensitivity analysis showed that the incremental net monetary benefit was positive (£3,708.58 (95% confidence intervals (CI) -£9,473.62 to £16,115.69) but the 95% CI includes zero, indicating that there is significant uncertainty about the cost-effectiveness of laparoscopic distal pancreatectomy versus open distal pancreatectomy. The probability laparoscopic distal pancreatectomy was cost-effective compared to open distal pancreatectomy for pancreatic cancer was between 70% and 80% at the willingness-to-pay thresholds generally used in England (£20,000 to £30,000 per QALY gained). Results were sensitive to the survival proportions and the operating time. There is considerable uncertainty about whether laparoscopic distal pancreatectomy is cost-effective compared to open distal pancreatectomy for pancreatic cancer in the NHS setting.

Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

To compare three ports laparoscopic cholecystectomy and four ports laparoscopic cholecystectomy in terms of complications, time taken to complete the procedure, hospital stay and cost effectiveness in local perspective. Methodology: This randomized control trial included 60 patients who underwent elective laparoscopic cholecystectomy at Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, Pakistan from January 2013 to June 2013. These patients were randomized on computer generated table of random numbers into group A and Group B. In Group A patients four ports were passed to perform laparoscopic cholecystectomy and in Group B patients three ports were passed to perform the procedure. Results: The mean age in both groups was 44 years (range 18-72). Three ports laparoscopic cholecystectomy (43 min) took less time to complete than four ports laparoscopic cholecystectomy (51 min). Patients in three ports laparoscopic cholecystectomy experienced less pain as compared to four ports group. The total additional analgesia requirement in 24 hours calculated in milligrams was less in three port laparoscopic cholecystectomy group as compared four port laparoscopic cholecystectomy group. The mean hospital stay in three port laparoscopic cholecystectomy group is 25 hours while the mean hospital stay in the four port laparoscopic cholecystectomy group is 28 hours. Conclusion: Three ports laparoscopic cholecystectomy is safe and effective procedure and it did not compromise the patient safety. (author)

Cholelithiasis is one of the most common disorders of the digestive tract encountered by general surgeons worldwide. Conventional or open cholecystectomy was the mainstay of treatment for a long time for this disease. In the 1980s laparoscopic surgery revolutionized the management of biliary tract diseases. It brought about a revolutionary change in the basic concepts of surgical principles and minimal access surgery gradually started to be acknowledged as a safe means of carrying out surgeries. To investigate the technical feasibility, safety and benefit of Single Incision Laparoscopic Cholecystectomy (SILC) versus Conventional Four Port Laparoscopic Cholecystectomy (C4PLC). This prospective randomized control trial was conducted to compare the advantages if any between the SILC and C4PLC. Thirty two patients underwent SILC procedure and C4PLC, each. The age of the patients ranged from 16-60years. Other demographic data and indications for cholecystectomy were comparable in both the groups. Simple comparative statistical analysis was carried out in the present study. Results on continuous variables are shown in Mean ± SD; whereas results on categorical variables are shown in percentage (%) by keeping the level of significance at 5%. Intergroup analysis of the various study parameters was done by using Fisher exact test. SPSS version 22 was used for statistical analysis. The mean operating time was higher in the SILC group (69 ± 4.00 mins vs. 38.53 ± 4.00 mins) which was of statistical significance (p=post-operative pain, with lesser analgesic requirements (p=operating time was longer otherwise it has almost similar clinical outcomes to those of C4PLC.

Laparoscopic correction of perforated peptic ulcer (PPU) has become an accepted way of management. Patch omentoplasty stayed for decades the main method of repair. The goal of the present study was to evaluate whether laparoscopic simple repair of PPU is as safe as patch omentoplasty. Since June 2005, 179 consecutive patients of PPU were treated by laparoscopic repair at our centers. We conducted a retrospective chart review in December 2012. Group I (patch group) included patients who were treated with standard patch omentoplasty. Group II (non-patch group) included patients who received simple repair without patch. From June 2007 to Dec. 2012, 179 consecutive patients of PPU who were treated by laparoscopic repair at our centers were enrolled in this multi-center retrospective study. 108 patients belong to patch group. While 71 patients were treated with laparoscopic simple repair. Operative time was significantly shorter in group II (non patch) (p = 0.01). No patient was converted to laparotomy. There was no difference in age, gender, ASA score, surgical risk (Boey's) score, and incidence of co-morbidities. Both groups were comparable in terms of hospital stay, time to resume oral intake, postoperative complications and surgical outcomes. Laparoscopic simple repair of PPU is a safe procedure compared with the traditional patch omentoplasty in presence of certain selection criteria. Copyright © 2013 Surgical Associates Ltd.

While laparoscopic donor nephrectomy has encouraged living kidney donation, debate exists about the safest laparoscopic technique. We compared purely laparoscopic and hand assisted laparoscopic donor nephrectomies in terms of donor outcome, early graft function and long-term graft outcome. We reviewed the records of consecutive laparoscopic and hand assisted laparoscopic donor nephrectomies performed by a single surgeon from 2002 to 2011. Donor operative time and perioperative morbidity were compared. Early graft function for kidneys procured by each technique was evaluated by rates of delayed graft function, need for dialysis and recipient discharge creatinine. Long-term outcomes were evaluated by graft function. A total of 152 laparoscopic donor nephrectomies were compared with 116 hand assisted laparoscopic donor nephrectomies. Hand assisted procedures were more often done for the right kidney (41.1% vs 17.1%, p recipient outcomes were also similar. Delayed function occurred after 0% hand assisted vs 0.9% purely laparoscopic nephrectomies, dialysis was required in 0.9% vs 1.7% and rejection episodes developed in 9.7% vs 18.4% (p >0.05). At last followup the organ was nonfunctioning in 6.1% of hand assisted and 7.7% of purely laparoscopic cases (p >0.05). The recipient glomerular filtration rate at discharge home was similar in the 2 groups. Hand assisted laparoscopic donor nephrectomy had shorter warm ischemia time but perioperative donor morbidity and graft outcome were comparable. The choice of technique should be based on patient and surgeon preference. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

The benefits of laparoscopic cholecystectomy, including rapid recovery and fewer infections, have been largely unavailable to the majority of people in developing countries. Compared to other countries, Mongolia has an extremely high incidence of gallbladder disease. In 2005, only 2% of cholecystectomies were performed laparoscopically. This is a retrospective review of the transition from open to laparoscopic cholecystectomy throughout Mongolia. A cross-sectional, retrospective review was conducted of demographic patient data, diagnosis type, and operation performed (laparoscopic versus open cholecystectomy) from 2005-2013. Trends were analyzed from 6 of the 21 provinces (aimags) throughout Mongolia, and data were culled from 7 regional diagnostic referral and treatment centers and 2 tertiary academic medical centers. The data were analyzed by individual training center and by year before being compared between rural and urban centers. We analyzed and compared 14,522 cholecystectomies (n = 4,086 [28%] men, n = 10,436 [72%] women). Men and women were similar in age (men 52.2, standard deviation 14.8; women 49.4, standard deviation 15.7) and in the percentage undergoing laparoscopic cholecystectomy (men 39%, women 42%). By 2013, 58% of gallbladders were removed laparoscopically countrywide compared with only 2% in 2005. In 2011, laparoscopic cholecystectomy surpassed open cholecystectomy as the primary method for gallbladder removal countrywide. More than 315 Mongolian health care practitioners received laparoscopic training in 19 of the country's 21 aimags (states). By 2013, 58% of cholecystectomies countrywide were performed laparoscopically, a dramatic increase over 9 years. The expansion of laparoscopic cholecystectomy has transformed the care of biliary tract disease in Mongolia despite the country's limited resources. Copyright © 2016 Elsevier Inc.

Esophageal achalasia in children is rare but ultimately requires endoscopic or surgical treatment. Historically, Heller esophagomyotomy has been recommended as the treatment of choice. The refinement of minimally invasive techniques has shifted the trend of treatment toward laparoscopic Heller myotomy (LHM) in adults and children with achalasia. A review of the available literature on LHM performed in patients 5 years) outcomes is needed. Due to the infrequency of achalasia in children, these characteristics are unlikely to be defined without collaboration between multiple pediatric surgery centers. The introduction of peroral endoscopic myotomy and single-incision techniques, continue the trend of innovative approaches that may eventually become the standard of care. PMID:26839646

Laparoscopic adrenalectomy: Single centre experience.

LENUS (Irish Health Repository)

O'Farrell, N J

2012-02-01

BACKGROUND: Laparoscopic adrenalectomy is an attractive alternative to the traditional open approach in the surgical excision of an adrenal gland. It has replaced open adrenalectomy in our institution and we review our experience to date. METHODS: All cases of laparoscopic adrenalectomies in our hospital over eight years (from 2001 to May 2009) were retrospectively reviewed. Patient demographics, diagnosis, length of hospital stay, histology and all operative and post-operative details were evaluated. RESULTS: Fifty-five laparoscopic adrenalectomies (LA) were performed on 51 patients over eight years. The mean age was 48 years (Range 16-86 years) with the male: female ratio 1:2. Twenty-three cases had a right adrenalectomy, 24 had a left adrenalectomy and the remaining four patients had bilateral adrenalectomies. 91% were successfully completed laparoscopically with five converted to an open approach. Adenomas (functional and non functional) were the leading indication for LA, followed by phaeochromocytomas. Other indications for LA included Cushing\\'s disease, adrenal malignancies and rarer pathologies. There was one mortality from necrotising pancreatitis following a left adrenalectomy for severe Cushing\\'s disease, with subsequent death 10 days later. CONCLUSION: Laparoscopic adrenalectomy is effective for the treatment of adrenal tumours, fulfilling the criteria for the ideal minimally invasive procedure. It has replaced the traditional open approach in our centre and is a safe and effective alternative. However, in the case of severe Cushing\\'s disease, laparoscopic adrenalectomy has the potential for significant adverse outcomes and mortality.

The role of laparoscopic surgery in the repair for peptic ulcer disease is unclear. The present study aimed to compare the safety and efficacy of laparoscopic versus open repair for peptic ulcer disease. Randomized controlled trials (RCTs) comparing laparoscopic versus open repair for peptic ulcer disease were identified from MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and references of identified articles and relevant reviews. Primary outcomes were postoperative complications, mortality, and reoperation. Secondary outcomes were operative time, postoperative pain, postoperative hospital stay, nasogastric tube duration, and time to resume diet. Statistical analysis was carried out by Review Manage software. Five RCTs investigating a total of 549 patients, of whom, 279 received laparoscopic repair and 270 received open repair, were included in the final analysis. There were no significant differences between these two procedures in some primary outcomes including overal postoperative complication rate, mortality, and reoperation rate. Subcategory analysis of postoperative complications showed that laparoscopic repair had also similar rates of repair site leakage, intra-abdominal abscess, postoperative ileus, pneumonia, and urinary tract infection as open surgery, except of the lower surgical site infection rate (P peptic ulcer. The obvious advantages of laparoscopic surgery are the lower surgical site infection rate, shorter nasogastric tube duration and less postoperative pain. However, more higher quality studies should be undertaken to further assess the safety and efficacy of laparoscopic repair for peptic ulcer disease. Copyright © 2016 IJS Publishing Group Ltd.

Innovative techniques have a really magical attraction for physicians as well as for patients. The number of robotic-assisted procedures worldwide has almost tripled from 80,000 procedures in the year 2007 to 205,000 procedures in 2010. In the same time the total number of Da Vinci surgery systems sold climbed from 800 to 1,400. Advantages, such as three-dimensional visualization, a tremor-filter, an excellent instrument handling with 6 degrees of freedom and better ergonomics, together with aggressive marketing led to a veritable flood of new Da Vinci acquisitions in the whole world. Many just took the opportunity to introduce a new instrument to save a long learning curve and start immediately in the surgical master class.If Da Vinci sacrocolpopexy is compared with the conventional laparoscopic approach, robotic-assisted sacrocolpopexy shows a significantly longer duration of the procedure, a higher need for postoperative analgesics, much higher costs and an identical functional outcome without any advantage over the conventional laparoscopic approach. Although the use of robotic-assisted systems shows a significantly lower learning curve for laparoscopic beginners, it only shows minimal advantages for the experienced laparoscopic surgeon. Therefore it remains uncertain whether robotic-assisted surgery shows a significant advantage compared to the conventional laparoscopic surgery, especially with small reconstructive laparoscopic procedures such as sacrocolpopexy.

To determine the role of laparoscopic surgery in the treatment of pediatric urachal disorders. Case reports and a literature review of laparoscopic excision of urachal remnants. In a five-year period, three children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms, and were treated by laparoscopic surgery. The average age was 8.3 years (range, 4-13),and there were two girls and one boy. Mean operative time was 90 minutes (range, 60-120), and there were nopostoperative complications. The three patients were all discharged by postoperative day four. Laparoscopy is an effective and safe minimally invasive technique in the management of pediatricurachal anomalies. It is effective even in cases of infected urachal cysts.

To measure the feasibility of using FMECA applied to the surgery and then compare the vulnerabilities of laparoscopic versus open appendectomy by using FMECA. The FMECA study was performed on each single selected phase of appendectomy and on complication-related data during the period January 1, 2009, to December 31, 2010. The risk analysis phase was completed by evaluation of the criticality index (CI) of each appendectomy-related failure mode (FM). The CI is calculated by multiplying the estimated frequency of occurrence (O) of the FM, by the expected severity of the injury to the patient (S), and the detectability (D) of the FM. In the first year of analysis (2009), 177 appendectomies were performed, 110 open and 67 laparoscopic. Eleven adverse events were related to the open appendectomy: 1 bleeding (CI: 8) and 10 postoperative infections (CI: 32). Three adverse events related to the laparoscopic approach were recorded: 1 postoperative infection (CI: 8) and 2 incorrect extractions of the appendix through the umbilical port (CI: 6). In the second year of analysis (2010), 158 appendectomies were performed, 69 open and 89 laparoscopic. Four adverse events were related to the open appendectomy: 1 incorrect management of the histological specimen (CI: 2), 1 dehiscence of the surgical wound (CI: 6), and 2 infections (CI: 6). No adverse events were recorded in laparoscopic approach. FMECA helped the staff compare the 2 approaches through an accurate step-by-step analysis, highlighting that laparoscopic appendectomy is feasible and safe, associated with a lower incidence of infection and other complications, reduced length of hospital stay, and an apparent lower procedure-related risk.

Although laparoscopic posterior fundoplication (LPF) i.e., Nissen or Toupet have the proven efficacy for controlling gastro-esophageal reflux surgically, there remain problems with postoperative dysphagia and gas bloat syndrome. To decrease some of these postoperative complications, laparoscopic anterior fundoplication (LAF) was introduced. The aim of this study was to conduct a meta-analysis and systematic review of randomized controlled trials (RCTs) to investigate the merits and drawbacks of LPF versus LAF for the treatment of gastro-esophageal reflux disease (GERD). A search of Medline, Embase, Science Citation Index, Current Contents, PubMed, ISI Web of Science, and the Cochrane Database identified all RCTs comparing different types of LPF and LAF published in the English Language between 1990 and 2013. The meta-analysis was prepared in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) statement. Data was extracted and analyzed on ten variables which include dysphagia score, heartburn rate, redo operative rate, operative time, overall complications, rate of conversion to open, Visick grading of satisfaction, overall satisfaction, length of hospital stay, and postoperative 24-h pH scores. Nine trials totaling 840 patients (anterior = 425, posterior = 415) were analyzed. There was a significant reduction in the odds ratio for dysphagia in the LAF group compared to the LPF group. Conversely, significant reduction in the odds ratio for heartburn was observed for LPF compared to LAF. Comparable effects were noted for both groups for other variables which include redo surgery, operating time, overall complications, conversion rate, Visick's grading, patients' satisfaction, length of hospital stay, and postoperative 24-h pH scores. Based on this meta-analysis, LPF compared to LAF is associated with significant reduction in heartburn at the expense of higher dysphagia rate on a short- and medium-term basis. We therefore

Although laparoscopic surgery is readily used in the management of inflammatory bowel disease (IBD) in adults, its role in the surgical treatment of IBD in the pediatric population is not well established. The aim of this narrative review was to analyze the published evidence comparing laparoscopic and open resection in the management of children and adolescents with IBD. The Pubmed and Embase databases were searched using the terms "inflammatory bowel disease," "children," "adolescents," "laparoscopic," and "colectomy." The review identified 10 appropriate studies. Even though laparoscopic surgery generally resulted in longer operating times (between a mean of 40 and 140 min), benefits included reduced postoperative pain (mean duration of opiate use 3 vs 6 days) and reduced length of stay (median length of stay 5-8 vs 10.5-19 days) compared with open surgery. Postoperative complication rates were similar following both approaches. Due to the limited available data and the small sample size of the published series, definite recommendations are not able to be drawn. Nevertheless, current evidence indicates that laparoscopic colorectal resection is safe and feasible in the management of IBD in the paediatric population, with reductions in postoperative pain and length of hospital stay achievable.

Electrocautery remains the main energy form used for dissection in laparoscopic cholecystectomy. However, due to its many risks the search continues for safer and more efficient forms of energy. This chapter assesses the outcomes of dissection using ultrasonic energy as compared to monopolar electrocautery during laparoscopic cholecystectomy. Studies included are trials of prospectively randomized adult patients with symptomatic gallstone disease subject either ultrasonic or monopolar electrocautery dissection during laparoscopic cholecystectomy. Seven trials were included in this review, with a total patient number of 695 randomized to two dissection methods: 340 in the electrocautery group and 355 in the ultrasonic group. Ultrasonic dissection is shown to be superior to monopolar electrocautery in laparoscopic cholecystectomy. Disadvantages include a difficult maneuvering technique and overall cost. Appropriate training programs may be implemented to overcome the first disadvantage, and it might be argued that given the combined cost of factors associated with standard clip and cautery technique, cost issues may be outweighed by the benefits of ultrasonic dissection. However, this necessitates further cost-benefit analysis.

Full Text Available Introduction. Single-incision laparoscopic colectomy (SILC is a viable and safe technique; however, there are no single-institution studies comparing outcomes of SILC for colon cancer with well-established minimally invasive techniques. We evaluated the short-term outcomes following SILC for cancer compared to a group of well-established minimally invasive techniques. Methods. Fifty consecutive patients who underwent SILC for colon cancer were compared to a control group composed of 50 cases of minimally invasive colectomies performed with either conventional multiport or hand-assisted laparoscopic technique. The groups were paired based on the type of procedure. Demographics, intraoperative, and postoperative outcomes were assessed. Results. With the exception of BMI, demographics were similar between both groups. Most of the procedures were right colectomies ( and anterior resections (. There were no significant differences in operative time (127.9 versus 126.7 min, conversions (0 versus 1, complications (14% versus 8%, length of stay (4.5 versus 4.0 days, readmissions (2% versus 2%, and reoperations (2% versus 2%. Oncological outcomes were also similar between groups. Conclusions. SILC is an oncologically sound alternative for the management of colon cancer and results in similar short-term outcomes as compared with well-established minimally invasive techniques.

To review surgical-site infection (SSI) and retrieval-site tumor recurrence rates in laparoscopic colorectal procedures when using a plastic freezer bag as a wound protector. Laparoscopic colorectal procedures where a plastic freezer bag used as a wound protector at the extraction site were reviewed between 1991 and 2008 from a prospectively collected database. χ test was used to compare SSI and tumor recurrence rates between groups. Costing data were obtained from the operating room supplies department. A total of 936 cases with 51 (5.45%) surgical-site infections were identified. SSI rates did not differ when comparing groups based on demographic factors, diagnosis, or location of procedure. Retrieval-site tumor recurrence rate was 0.21% (1/474). Cost of plastic freezer bags including sterilization ranged from $0.25 to $3. Plastic freezer bags as wound protectors in laparoscopic colorectal procedures are cost effective and have SSI and retrieval-site tumor recurrence rates that compare favorably to published data.

We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15-80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (Pincarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative.

An overview of laparoscopic sterilization techniques from a historical and practical viewpoint includes instrumentation, operative techniques, mechanical occlusive devices, anesthesia, failure rates, morbidity and mortality. Laparoscope was first reported in 1893, but was developed simultaneously in France, Great Britain, Canada and the US in the 1960s. There are smaller laparoscopes for double-puncture procedures, and larger, single-puncture laparoscopes. To use a ring or clip, a much larger operating channel, up to 8 mm is needed. Insufflating gas may be CO2, which does not support combustion, but is more uncomfortable, NO2, which is also an anesthetic, and room air often used in developing countries. Unipolar electrocautery is now rarely used, in fact most third party payers do not allow it. Bipolar cautery, thermal coagulation and laser photocoagulation are safer methods. Falope rings, Hulka-Clemens, Filshie, Bleier, Weck and Tupla clips are described and illustrated. General anesthesia, usually a short acting agent with a muscle relaxant, causes 33% of the mortality of laparoscope, often due to cardiac arrest and arrhythmias, preventable with atropine. Local anesthesia is safer and cheaper and often used in developing countries. Failure rates of the various laparoscopic tubal sterilization methods are reviewed: most result from fistula formation. Mortality and morbidity can be caused by bowel damage, injury or infection, pre- existing pelvic infection, hemorrhage, gas embolism (avoidable by the saline drip test), and other rare events.

Laparoscopic distal pancreatectomy for adenocarcinoma: safe and reasonable?

Science.gov (United States)

Postlewait, Lauren M.

2015-01-01

As a result of technological advances during the past two decades, surgeons now use minimally invasive surgery (MIS) approaches to pancreatic resection more frequently, yet the role of these approaches for pancreatic ductal adenocarcinoma resections remains uncertain, given the aggressive nature of this malignancy. Although there are no controlled trials comparing MIS technique to open surgical technique, laparoscopic distal pancreatectomy for pancreatic adenocarcinoma is performed with increasing frequency. Data from retrospective studies suggest that perioperative complication profiles between open and laparoscopic distal pancreatectomy are similar, with perhaps lower blood loss and fewer wound infections in the MIS group. Concerning oncologic outcomes, there appear to be no differences in the rate of achieving negative margins or in the number of lymph nodes (LNs) resected when compared to open surgery. There are limited recurrence and survival data on laparoscopic compared to open distal pancreatectomy for pancreatic adenocarcinoma, but in the few studies that assess long term outcomes, recurrence rates and survival outcomes appear similar. Recent studies show that though laparoscopic distal pancreatectomy entails a greater operative cost, the associated shorter length of hospital stay leads to decreased overall cost compared to open procedures. Multiple new technologies are emerging to improve resection of pancreatic cancer. Robotic pancreatectomy is feasible, but there are limited data on robotic resection of pancreatic adenocarcinoma, and outcomes appear similar to laparoscopic approaches. Additionally fluorescence-guided surgery represents a new technology on the horizon that could improve oncologic outcomes after resection of pancreatic adenocarcinoma, though published data thus far are limited to animal models. Overall, MIS distal pancreatectomy appears to be a safe and reasonable approach to treating selected patients with pancreatic ductal

Full Text Available Rationale: One of the most complicated and unresolved problems in clinical medicine is the choice of an optimal method for organ-preservation treatment of uterine fibroids in women of childbearing age. Aim: To assess clinical efficacy of robot-assisted laparoscopic myomectomy. Materials and methods: The search was performed in PubMed, Embase, Trip, Cochrane, DocMe databases by keywords: “fibroids”, “robot”, “da Vinci”, “robotic myomectomy”, “robot-assisted myomectomy”. Results: We found 25 publications on robot-assisted laparoscopic myomectomy, including 6  papers on its reproductive outcomes (levels of evidence II–IV. Duration of robot-assisted surgery ranged from 132 to 261 minutes, intraoperative blood loss was in the range from 50 to 387 mL, postoperative hospital stay ranged from 1 to  3.9  days. There was a  lower percentage of intra- and postoperative complications after the robot-assisted interventions, compared to abdominal or classic laparoscopic access, as well as a lower percentage of conversion laparotomies compared to laparoscopy. Pregnancy rates after robotic myomectomy ranged from 16.7 to 69%. Only one case of uterine rupture after robot-assisted laparoscopic myomectomy has been described in the literature. Conclusion: Due to high cost of the method, the number of conducted studies is insufficient to evaluate the role of robotic technologies in the organ-preservation approach to uterine fibroids. Nevertheless, they suggest that robot-assisted laparoscopic myomectomy is justified in women of childbearing age who are planning pregnancy, with big centripetally growing intramural nodes and deformation of the uterine cavity. This technique on its own is an independent method for fertility restoration and could be the first step before the use of assisted reproductive technology.

Training in laparoscopic surgery is important not only to acquire and improve skills but also avoid the loss of acquired abilities. The aim of this single-centre, prospective randomized study was to assess skill acquisition of different laparoscopic techniques and identify the point in time when acquired skills deteriorate and training is needed to maintain these skills. Sixty surgical novices underwent laparoscopic surgery (LS) and single-incision laparoscopic surgery (SILS) baseline training (BT) performing two validated tasks (peg transfer, precision cutting). The novices were randomized into three groups and skills retention testing (RT) followed after 8 (group A), 10 (group B) or 12 (group C) weeks accordingly. Task performance was measured in time with time penalties for insufficient task completion. 92 % of the participants completed the BT and managed to complete the task in the required time frame of proficiency. Univariate and multivariate analyses revealed that SILS (P skills (comparison of BT vs RT) was not identified; however, for SILS a significant deterioration of skills (adjustment of BT and RT values) was demonstrated for all groups (A-C) (P skills more difficult to maintain. Acquired LS skills were maintained for the whole observation period of 12 weeks but SILS skills had begun to deteriorate at 8 weeks. These data show that maintenance of LS and SILS skills is divergent and training curricula need to take these specifics into account.

Full Text Available Background. In laparoscopic surgery errors are unavoidable and require proper acknowledgment to reduce the risk of intraoperative and accurately assess the appropriate therapeutic approach. Fortunately, their frequency is low and cannot overshadow the benefits of laparoscopic surgery. Materials and Methods. We made an epidemiological investigation in General Surgery Department of Emergency Clinical Hospital "St. John" Bucharest, analyzing 20 years of experience in laparoscopic surgery, during 1994-2014. We wanted to identify evolution trends in complications of laparoscopic surgery, analyzing the dynamic of errors occurred in all patients with laparoscopic procedures. Results. We recorded 26847 laparoscopic interventions with a total of 427 intra-or postoperative complications that required 160 conversions and 267 reinterventions to resolve inconsistencies. The average frequency of occurrence of complications was 15.9‰ (15.9 of 1,000 cases. In the period under review it was a good momentum of laparoscopic procedures in our department. Number of minimally invasive interventions increased almost 10 times, from 266 cases operated laparoscopically in 1995 to 2638 cases in 2008. Annual growth of the number of laparoscopic procedures has surpassed the number of complications. Conclusions. Laborious work of laparoscopic surgery and a specialized centre with well-trained team of surgeons provide premises for a good performance even in the assimilation of new and difficult procedures.

Diverticular disease is a common condition in Western industrialised countries. Most individuals remain asymptomatic throughout life; however, 25% experience acute diverticulitis. The standard treatment for acute diverticulitis is open surgery. Laparoscopic surgery - a minimal-access procedure - offers an alternative approach to open surgery, as it is characterised by reduced operative stress that may translate into shorter hospitalisation and more rapid recovery, as well as improved quality of life. To evaluate the effectiveness of laparoscopic surgical resection compared with open surgical resection for individuals with acute sigmoid diverticulitis. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2) in the Cochrane Library; Ovid MEDLINE (1946 to 23 February 2017); Ovid Embase (1974 to 23 February 2017); clinicaltrials.gov (February 2017); and the World Health Organization (WHO) International Clinical Trials Registry (February 2017). We reviewed the bibliographies of identified trials to search for additional studies. We included randomised controlled trials comparing elective or emergency laparoscopic sigmoid resection versus open surgical resection for acute sigmoid diverticulitis. Two review authors independently selected studies, assessed the domains of risk of bias from each included trial, and extracted data. For dichotomous outcomes, we calculated risk ratios (RRs) with 95% confidence intervals (CIs). For continuous outcomes, we planned to calculate mean differences (MDs) with 95% CIs for outcomes such as hospital stay, and standardised mean differences (SMDs) with 95% CIs for quality of life and global rating scales, if researchers used different scales. Three trials with 392 participants met the inclusion criteria. Studies were conducted in three European countries (Switzerland, Netherlands, and Germany). The median age of participants ranged from 62 to 66 years; 53% to 64% were

Laparoscopic surgery has become the treatment of choice for the management of perforated peptic ulcer. The advantages of laparoscopic repair for perforated peptic ulcer include less pain, a short hospital stay, and an early return to normal activity. Although the operation time of laparoscopic surgery is significantly longer than that of open surgery, laparoscopic technique is safe, feasible, and with morbidity and mortality comparable to that of the conventional open technique. To benefit from the advantages offered by minimally invasive laparoscopic technique, further study will need to determine whether laparoscopic surgery is safe in patients with generalized peritonitis or sepsis.

Role of Epidural Analgesia within an ERAS Program after Laparoscopic Colorectal Surgery: A Review and Meta-Analysis of Randomised Controlled Studies

Full Text Available Introduction. Epidural analgesia has been a cornerstone of any ERAS program for open colorectal surgery. With the improvements in anesthetic and analgesic techniques as well as the introduction of the laparoscopy for colorectal resection, the role of epidural analgesia has been questioned. The aim of the review was to assess through a meta-analysis the impact of epidural analgesia compared to other analgesic techniques for colorectal laparoscopic surgery within an ERAS program. Methods. Literature research was performed on PubMed, Embase, and the Cochrane Library. All randomised clinical trials that reported data on hospital stay, postoperative complications, and readmissions rates within an ERAS program with and without an epidural analgesia after a colorectal laparoscopic resection were included. Results. Five randomised clinical trials were selected and a total of 168 patients submitted to epidural analgesia were compared to 163 patients treated by an alternative analgesic technique. Pooled data show a longer hospital stay in the epidural group with a mean difference of 1.07 (95% CI 0.06–2.08 without any significant differences in postoperative complications and readmissions rates. Conclusion. Epidural analgesia does not seem to offer any additional clinical benefits to patients undergoing laparoscopic colorectal surgery within an ERAS program.

Full Text Available According to a nation-wide population-based study in Taiwan, along with the expanding concepts and surgical techniques of minimally invasive surgery, laparoscopic supracervical/subtotal hysterectomy (LSH has been blooming. Despite this, the role of LSH in the era of minimally invasive surgery remains uncertain. In this review, we tried to evaluate the perioperative and postoperative outcomes of LSH compared to other types of hysterectomy, including total abdominal hysterectomy (TAH, vaginal hysterectomy, laparoscopic-assisted vaginal hysterectomy, and total laparoscopic hysterectomy (TLH. From the literature, LSH has a better perioperative outcome than TAH, and comparable perioperative complications compared with laparoscopic-assisted vaginal hysterectomy. LSH had less bladder injury, vaginal cuff bleeding, hematoma, infection, and dehiscence requiring re-operation compared with TLH. Despite this, LSH has more postoperative cyclic menstrual bleeding and re-operations with extirpations of the cervical stump. LSH does, however, have a shorter recovery time than TAH due to the minimally invasive approach; and there is quicker resumption of coitus than TLH, due to cervical preservation and the avoidance of vaginal cuff dehiscence. LSH is therefore an alternative option when the removal of the cervix is not strictly necessary or desired. Nevertheless, the risk of further cervical malignancy, postoperative cyclic menstrual bleeding, and re-operations with extirpations of the cervical stump is a concern when discussing the advantages and disadvantages of LSH with patients.

To report our experience and review published reports on the laparoscopic management of peripelvic renal cysts. Peripelvic renal cysts represent a unique subset of renal cysts, as they are rare, commonly symptomatic, and more difficult to treat than simple peripheral renal cysts. Minimally invasive methods for the treatment of peripelvic renal cysts, including laparoscopic decortication, have recently become more common. Four patients who presented with symptomatic peripelvic cysts underwent laparoscopic decortication at our institution. All four were men aged 47 to 65 years. One patient had undergone an unsuccessful prior cyst aspiration. All patients underwent preoperative computed tomography and retrograde pyelography. The mean number of peripelvic cysts per patient was 3.0, and the mean cyst size was 7.1 cm. The mean operative time was 259 minutes (range 240 to 293), and the mean estimated blood loss was 30 mL (range 10 to 50). No evidence of cystic renal cell carcinoma was found on aspiration cytology or cyst wall pathologic examination. The mean hospital stay was 1.3 days. No inadvertent collecting system injuries and no intraoperative or postoperative complications occurred. All 4 patients achieved symptomatic relief and were determined to have radiologic success as determined by the 6-month postoperative computed tomography findings. Laparoscopic ablation of peripelvic renal cysts is more difficult than that of simple peripheral renal cysts and demands a heightened awareness of potential complications and, therefore, more advanced surgical skills. In addition to our experience, a thorough review of published reports found this procedure to be safe and effective with appropriate patient selection.

Full Text Available ABSTRACT Objective: to evaluate the pulmonary function of women submitted to conventional and single-port laparoscopic cholecystectomy. Methods: forty women with symptomatic cholelithiasis, aged 18 to 70 years, participated in the study. We divided the patients into two groups: 21 patients underwent conventional laparoscopic cholecystectomy, and 19, single-port laparoscopic cholecystectomy. We assessed pulmonary function through forced vital capacity (FVC, forced expiratory volume in the first second (FEV1, and the FEV1/FVC ratio, measured before and 24 hours after the procedure. Results: in both groups, FVC and FEV1 were lower in the postoperative period than those obtained in the preoperative period, with a greater reduction in the group undergoing conventional laparoscopic cholecystectomy. Regarding the FEV1/FVC (% values, there was no statistically significant difference in any of the groups or times analyzed. Conclusion: there was a greater decline in FVC and FEV1 in the postoperative group of patients submitted to conventional laparoscopic cholecystectomy.

Objective: Although the anterior approach is normally used for elective laparoscopic splenectomy (LS), the posterolateral approach may be superior. We have retrospectively compared the effectiveness and safety of these approaches in patients with non-severe splenomegaly scheduled for elective total LS. Methods: Patients with surgical spleen disorders scheduled for elective LS between March 2005 and June 2011 underwent laparoscopic splenic mobilization via the posterolateral or anterior approach. Main outcome measures included operation time, intraoperative blood loss, frequency of postoperative pancreatic leakage, and length of hospital stay. Results: During the study period, 203 patients underwent LS, 58 (28.6%) via the posterolateral and 145 (71.4%) via the anterior approach. Three patients (1.5%) required conversion to laparotomy due to extensive perisplenic adhesions. The posterolateral approach was associated with significantly shorter operation time (65.0 ± 12.3 min vs. 95.0 ± 21.3 min, P 0.05) Conclusions: The posterolateral approach is more effective and safer than the anterior approach in patients without severe splenomegaly (< 30 cm).

Laparoscopic radical nephroureterectomy: dilemma of the distal ureter.

Science.gov (United States)

Steinberg, Jordan R; Matin, Surena F

2004-03-01

Laparoscopic nephroureterectomy has recently emerged as a safe, minimally invasive approach to upper tract urothelial cancers. The most controversial and challenging feature of laparoscopic nephroureterectomy is the management of the distal ureter. We review the most common methods of managing the distal ureter, with emphasis on contemporary oncologic outcomes, indications, advantages, and disadvantages. There are currently in excess of five different approaches to the lower ureter. These techniques often combine features of endoscopic, laparoscopic, or open management. They include open excision, a transvesical laparoscopic detachment and ligation technique, laparoscopic stapling of the distal ureter and bladder cuff, the "pluck" technique, and ureteral intussusception. Each technique has distinct advantages and disadvantages, differing not only in technical approach, but oncological principles as well. While the existing published data do not overwhelmingly support one approach over the others, the open approach remains one of the most reliable and oncologically sound procedures. The principles of surgical oncology dictate that a complete, en-bloc resection, with avoidance of tumor seeding, remains the preferred treatment of all urothelial cancers. The classical open technique of securing the distal ureter and bladder cuff achieves this principle and has withstood the test of time. Transvesical laparoscopic detachment and ligation is an oncologically valid approach in patients without bladder tumors, but is limited by technical considerations. The laparoscopic stapling technique maintains a closed system but risks leaving behind ureteral and bladder cuff segments. Both transurethral resection of the ureteral orifice (pluck) and intussusception techniques should be approached with caution, as the potential for tumor seeding exists. Additional long-term comparative outcomes are needed to solve the dilemma of the distal ureter.

OBJECTIVE To estimate the probability of successful sterilization after hysteroscopic or laparoscopic sterilization procedure. METHODS An evidence-based clinical decision analysis using a Markov model was performed to estimate the probability of a successful sterilization procedure using laparoscopic sterilization, hysteroscopic sterilization in the operating room, and hysteroscopic sterilization in the office. Procedure and follow-up testing probabilities for the model were estimated from published sources. RESULTS In the base case analysis, the proportion of women having a successful sterilization procedure on first attempt is 99% for laparoscopic, 88% for hysteroscopic in the operating room and 87% for hysteroscopic in the office. The probability of having a successful sterilization procedure within one year is 99% with laparoscopic, 95% for hysteroscopic in the operating room, and 94% for hysteroscopic in the office. These estimates for hysteroscopic success include approximately 6% of women who attempt hysteroscopically but are ultimately sterilized laparoscopically. Approximately 5% of women who have a failed hysteroscopic attempt decline further sterilization attempts. CONCLUSIONS Women choosing laparoscopic sterilization are more likely than those choosing hysteroscopic sterilization to have a successful sterilization procedure within one year. However, the risk of failed sterilization and subsequent pregnancy must be considered when choosing a method of sterilization. PMID:21775842

The aim of the present study was to assess the impact of a novel posterior reconstruction technique during robot-assisted laparoscopic prostatectomy on continence recovery. A total of 116 consecutive patients who received the novel posterior reconstruction (case group) were retrospectively compared with a cohort of 126 patients who did not receive posterior reconstruction (control group). The primary end-point was the duration of continence recovery (no pad use) after robot-assisted laparoscopic prostatectomy. The posterior reconstruction was obtained by opposing the median dorsal fibrous raphe to the posterior counterpart of the detrusor apron, rather than the Denonvilliers' fascia. The case group showed higher continence rates at all points of evaluation, which were 2 weeks (30.1% vs 19.8%), 1 month (58.4% vs 45.7%), 3 months (82.7% vs 70.5%) and 6 months postoperatively (95.3% vs 86.4%) (P = 0.007). Application of the novel posterior reconstruction technique, age and length of membranous urethra were significant variables for the complete recovery of continence on multivariable analysis. This study shows that the application of this novel PR technique significantly improves the recovery of continence in patients undergoing robot-assisted laparoscopic prostatectomy. © 2012 The Japanese Urological Association.

A retrospective review of medical records was performed to assess the incidence and type of significant complications encountered during laparoscopic hysterectomy Two hundred and sixty-five consecutive patients were reviewed between the years 1994 and August 2001. Two hundred and thirty-two laparoscopic vaginal hysterectomies and 33 total laparoscopic hysterectomies were performed. The operations were performed at Monash Medical Centre, a Melbourne tertiary public hospital, and two Melbourne private hospitals, by three surgeons. Ten significant complications occurred. There were two cases of ureteric fistula, two bladder injuries, two bowel obstructions, two postoperative haematomas, one case of a bladder fistula and one superficial epigastric artery injury. In-patient stay ranged from two to six days. Our complication and in-patient stay rates are consistent with previously reported rates.

Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black boxes and simulators were included. The results indicated any kind of simulator training (black box, VR) to be beneficial at novice level. After VR training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. No clinical follow-up data were found. Optimal learning requires skills training to be conducted as part of a systematic training program. No data on the cost-benefit of simulators were found, the price of a VR simulator begins at EUR 60 000. Theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. The cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. In order to achieve optimal learning a validated training program is needed.

Full Text Available Irene Sellbrant,1 Gustaf Ledin,2 Jan G Jakobsson2 1Department of Anaesthesia, Capio Lundby, Gothenburg, 2Department of Anaesthesia and Intensive Care, Institution for Clinical Science, Karolinska Institutet, Danderyds Hospital, Stockholm, Sweden Abstract: Laparoscopic cholecystectomy is one of the most common general surgical procedures. The aim of the present paper is to review current evidence and well-established practice for elective laparoscopic perioperative management. There is no firm evidence for best anesthetic technique, further high quality studies assessing short as well as more protracted outcomes are needed. Preventive multi-modal analgesia, combining non-opioid analgesics, paracetamol, nonsteroidal anti-inflammatory drugs or coxib, and local anesthesia, has a long history. Local anesthesia improves postoperative pain and facilitates discharge on the day of surgery. Whether transversus abdominis plane-block has clinically important advantages compared to local infiltration analgesia needs further studies. Single intravenous dose steroid, dexamethasone, reduces postoperative nausea and vomiting, pain, and enhances the recovery process. Multi-modal analgesia is reassuringly safe thus having a positive benefit versus risk profile. Adherence to modern guidelines avoiding prolonged fasting and liberal intravenous fluid regime supports rapid recovery. The effects of CO2 insufflation must be acknowledged and low intra-abdominal pressure should be sought in order to reduce negative cardiovascular/respiratory effects. There is no firm evidence supporting heating and humidification of the insufflated gas. The potential risk for CO2/gas entrainment into vasaculture, gas emboli, or subcutaneous/intra-thoracic into the pleural space must be kept in mind. Laparoscopic cholecystectomy in ASA 1-2 patients following a multi-modal enhanced recovery protocol promotes high success rate for discharge on the day of surgery. Keywords: laparoscopic

A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications. Copyright 2001 Academic Press.

Appendicovesicostomy is commonly employed to facilitate drainage of urine through the catheter. Due to the tendency to less invasive procedures for the treatment of patients with neurogenic bladder, laparoscopy has been used as an alternative to open surgery, with the immediate advantages of postoperative recovery, shorter postoperative ileus, better cosmetic results, lower postoperative pain and early reintegration into everyday life. Compare the results of laparoscopic procedure with open appendicovesicostomy. We conducted an observational, analytical, longitudinal, ambispective cohort study, which included patients from 6-16 years of age diagnosed with neurogenic bladder, operated through laparoscopic and open appendicovesicostomy from January 2009 to June 2013. Information was obtained from clinical records. Six patients were operated laparoscopically and 14 by open approach. Surgical time was longer and statistically significant in the laparoscopic group with a median of 330 min (300-360 min) compared to open procedure of 255 min (180-360 min). Seven patients had complications in the open group and only one in the laparoscopic group. The difference in the dose of analgesics and time of use was statistically significant in favor of the laparoscopic group. The degree of urinary continence through the stoma was higher for laparoscopic (100%) compared to the open procedure (64%). In neurogenic bladder with urodynamic bladder capacity and leak point pressure bladder within acceptable values, laparoscopic appendicovesicostomy was a better alternative.

To evaluate the Single-Incision Transumbilical Surgery (SITUS) technique as compared to an established laparoendoscopic single-site surgery (LESS) technique (Single-Port Laparoscopic Surgery, SPLS) and conventional laparoscopy (CLS) in a surgical simulator model. Sixty-three medical students without previous laparoscopic experience were randomly assigned to one of the three groups (SITUS, SPLS and CLS). Subjects were asked to perform five standardized tasks of increasing difficulty adopted from the Fundamentals of Laparoscopic Surgery curriculum. Statistical evaluation included task completion times and accuracy. Overall performances of all tasks (except precision cutting) were significantly faster and of higher accuracy in the CLS and SITUS groups than in the SPLS group (p = 0.004 to p port-assisted LESS technique such as SPLS. The demonstrated advantages of SITUS may be attributed to a preservation of the basic principles of conventional laparoscopy, such as the use of straight instruments and an adequate degree of triangulation.

This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

Current status of laparoscopic central pancreatectomy

Full Text Available Central pancreatectomy is an ideal surgical procedure for the treatment of benign or low-grade malignant tumors in the pancreatic neck or the proximal body of the pancreas, and it can preserve more normal pancreatic tissue in order to reduce the incidence of endocrine and exocrine insufficiency after surgery. Although some clinical studies have demonstrated the feasibility and safety of this procedure, laparoscopic central pancreatectomy was technically challenging with a few number of cases. This article reviews the current status of laparoscopic central pancreatectomy and introduces our clinical experience of laparoscopic central pancreatectomy and pancreaticojejunostomy.

Since its introduction in the early 1990s, laparoscopic splenectomy (LS) has gained worldwide acceptance for spleen removal, especially in hematological patients. The present review summarizes the current knowledge and results of LS for the treatment of benign hematological diseases in adults. A MEDLINE/PubMed database research was performed using the terms: "laparoscopic splenectomy" OR "laparoscopy" OR "splenectomy" AND "hematological disorders" OR "hematological disease" OR "hematology" AND "adults" as key words. We set our analysis starting date as January 1st 2010 and the end date as December 31st 2016. We identified 247 relative articles. All the references from the identified articles were searched for relevant information. Twenty-seven articles were deemed appropriate for our analysis. LS was found to be feasible and safe in the majority of patients with benign hematological disorders, with a mortality rate ranging from 0% to less than 4% and the postoperative complications rate from 0% to 35.7%. The conversion rate was also very low (4%) and response (complete or partial) was achieved in more than 80% of patients. Lateral approach with four trocars was the most commonly used approach with concommitant cholecystectomy being correlated with increased operative time and morbidity. Current literature holds that whenever splenectomy is required for the treatment of hematological disorders in adults, a laparoscopic approach should be offered as the gold standard. However, to strengthen the clinical evidence in favor of LS, more high-quality clinical trials on several issues of the procedure are necessary.

Preoperative, intraoperative and postoperative risk factors for anastomotic leakage after laparoscopic low anterior resection with double stapling technique anastomosis.

Science.gov (United States)

Kawada, Kenji; Sakai, Yoshiharu

2016-07-07

Anastomotic leakage (AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection (LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR.

The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, Pstudy showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

Advantages and disadvantages of open and endoscopic hernia surgery are still being discussed. Until now there has been no study that evaluated the advantages and disadvantages of bilateral hernia repair in a large number of patients. Our prospectively collected database was analyzed to compare the results of laparoscopic bilateral with laparoscopic unilateral hernia repair. We then compared these results with the results of a literature review regarding open and laparoscopic bilateral hernia repair. From April 1993 to December 2007 there were 7240 patients with unilateral primary hernia (PH) and 2880 patients with bilateral hernia (5760 hernias) who underwent laparoscopic transabdominal preperitoneal patch plastic (TAPP). Of the 10,120 patients, 28.5% had bilateral hernias. Adjusted for the number of patients operated on, the mean duration of surgery for unilateral hernia repair was shorter than that for bilateral repair (45 vs. 70 min), but period of disability (14 vs. 14 days) was the same. Adjusted for the number of hernias repaired, morbidity (1.9 vs. 1.4%), reoperation (0.5 vs. 0.43%), and recurrence rate (0.63 vs. 0.42%) were similar for unilateral versus bilateral repair, respectively. The review of the literature shows a significantly shorter time out of work after laparoscopic bilateral repair than after the bilateral open approach. Simultaneous laparoscopic repair of bilateral inguinal hernias does not increase the risk for the patient and has an equal length of down time compared with unilateral repair. According to literature, recovery after laparoscopic repair is faster than after open simultaneous repair. Laparoscopic/endoscopic inguinal hernia repair of bilateral hernias should be recommended as the gold standard.

To compare the operative outcome, morbidity profile, and functional outcome after transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in unusual circumstances (intrinsic pathology in anomalous kidneys or unusual extrinsic pathologies; group 1) to the outcome after this procedure in familiar pathologies (normally located kidneys with intrinsic dysfunctional segment or extrinsic compression due to a crossing vessel; group 2). The patients were evaluated in detail. All patients underwent transperitoneal laparoscopic dismembered pyeloplasty. The operative and postoperative parameters were recorded. Patients were followed up after the procedure on a 3-month protocol. Imaging was repeated at 1 year. No intervention during the follow-up period (ie, nephrostomy, ureteral stenting, or redo pyeloplasty) and improvement in the hydronephrosis grade and diuretic renogram parameters was interpreted as procedural success. The operative, postoperative, and follow-up parameters in the 2 groups were compared. Group 1 included 17 patients with intrinsic pathologic features and renal anomalies with ureteropelvic junction obstruction due to unusual extrinsic pathology. All procedures were successfully completed with the laparoscopic approach. A significant difference was noted in the mean operative duration (group 1, 196.9 ± 10.3 minutes; group 2, 125.44 minutes, P = .00). The other operative and postoperative parameters were comparable. No significant operative or postoperative events were noted. A total of 14 patients (group 1) completed the 1-year follow-up protocol. The success rate was 92.9% (13 of 14) in group 1 and 97.9% (44 of 45) in group 2 (P = .42). The procedural duration for laparoscopic dismembered pyeloplasty in unusual circumstances is longer than in familiar pathologies. However, the morbidity profile and functional outcome in these 2 scenarios were comparable. Copyright © 2012 Elsevier Inc. All rights reserved.

Full Text Available Introduction. Laparoscopic appendectomy (LA has been performed in many approaches such as open, laparoscopic and recently Single Port Access (SPAA. In order to elucidate its potential advantages, we compared the two laparoscopic approaches. Methods. 87 patients were included in a multicentric study for suspected appendicitis in order to perform (SPAA appendectomy or laparoscopic appendectomy (LA. All outcomes, including blood loss, operative time, complications, and length of stay and pain were recorded prospectively. Results. There were 46 patients in the SPAA group and 41 in the LAG with a mean operative time of 40,4 minutes in the SPAA group and 35,0 minutes in the LA group. Only one patient was converted to an open approach. We described only 2 complications. Pain was graded 2,8 in the SPAA group and 2,9 in the LA group, according to the AVS after 24 hours. Patients in the SPAA Group were more satisfied (7,5 versus 6,9 (<0.05. Same results were found for the cosmetic result (8,6 versus 7,4 (<0.05. Conclusion. Using the single port approach feasible and safe. The true benefit of the technique should be assessed by new randomised controlled trials.

Full Text Available Management of renal stone in crossed fused renal ectopia (CFRE is difficult because of abnormal location, malrotation, and its relations with vertebral column and small bowel. Management is not standardized because of the paucity of literature and variable anatomy. We managed an 8-year-old boy with multiple renal stones in right side crossed kidney by laparoscopic pyelolithotomy and nephro pyeloscopy with the help of ureteroscope. Until now, there is only one prior report of laparoscopic pyelolithotomy in CFRE. We share our experience in this case and review the literature regarding the management of kidney stones in this rare anomaly.

Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery. This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis. We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7%) patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique); 21 (30%) patients underwent peritoneal laparoscopic lavage; 4 (5.7%) patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6%) patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy. The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients). In the LPL group the morbidity rate was 33.3%. Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage.

A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy and 10 patients underwent LAMP. The same surgeon performed all the surgeries. The 2 procedures were compared in terms of tumor size, operating time, time to resumption of a soft diet, length of hospital day, and postoperative complications. The 2 groups were similar in terms of tumor size (30.08 vs. 32.50 mm, P=0.796), mean operating time (112.9 vs. 127 min, P=0.316), time to resumption of a soft diet (1.25 vs. 1.30 d, P=0.805), and length of hospital day (4.08 vs. 4.50 d, P=0.447). Despite 1 patient in the LAMP group experiencing ipsilateral pleural effusion as a postoperative complication, this parameter was similar for the 2 groups (P=0.195). Perioperative mortality, blood transfusion, and conversion to open surgery did not occur. Perioperative outcomes for LAMP were similar to those for conventional laparoscopic adrenalectomy. LAMP appears to be a feasible option for adrenalectomy.

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

In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

Postoperative admission for acute appendicitis utilizes health care system resources. We evaluated outcomes and hospital charges for children with nonperforated appendicitis who underwent outpatient laparoscopic appendectomy. A retrospective chart review was performed for patients ≤18years old who underwent laparoscopic appendectomy for acute appendicitis in 2015. Patients were categorized into discharge from postanesthesia care unit (PACU) (outpatient), admission for 24-h. Continuous variables were compared using analysis of variance and categorical variables were compared using chi-square test, with p24-h. There were no differences in postoperative emergency department/clinic visits, complications, or readmissions. Hospital charges for admission 24-h were $1007 and $2237 more per patient than the PACU-discharge group, respectively. Outpatient laparoscopic appendectomies became more common over time, occurring in only 20% of patients with acute appendicitis in the first quarter of the year versus 49% of patients in the last quarter. Outpatient laparoscopic appendectomy for nonperforated appendicitis in children is a safe practice that decreases length of stay and hospital charges. Adoption of an outpatient strategy allows for better standardization of care and can lead to savings in health care resources. III (Treatment: retrospective comparative study).

2005-01-01

Full Text Available The present study is undertaken to establish the usefulness of laparoscopic cholecystectomy and to know its merits and demerits as compared to open cholecystectomy in children. In all, 28 patients who underwent cholecystectomy (8 open and 20 laparoscopic cholecystectomy in B.Y.L. Nair hospital between July 1999 and March 2004 were analyzed. Calculous cholecystitis was found to be the most common indication for surgery. Operative time for laparoscopic cholecystectomy was more than that in open cholecystectomy in the early phase of laparoscopy, which got reduced as we gained experience. The requirement of parenteral antibiotics and analgesics and the duration of stay were significantly shorter with laparoscopy. The advantages for a child in laparoscopic cholecystectomy as compared to open cholecystectomy are minimal pain, avoidance of an upper abdominal incision, cosmesis and shorter duration of hospitalization with quick return to home and school. Thus, laparoscopic cholecystectomy is safe and efficacious in children.

Over the last decade, robotic approaches have been described for removing adrenal tumors. Although there are reports comparing robotic and laparoscopic techniques in general, there are limited data on outcomes in patients with primary hyperaldosteronism (PHA). The aim of this study is to compare the safety and efficacy of robotic adrenalectomy (RA) versus laparoscopic adrenalectomy (LA) for PHA. The records of 20 patients who underwent RA for PHA were compared with 16 patients who underwent LA between 2000 and 2014. Data were retrospectively reviewed from a prospectively maintained, IRB-approved adrenal database. Statistical analysis was performed using t test and the Fisher exact analysis. Continuous variables are reported as mean±SEM. Demographic and clinical parameters were similar between the groups. There were no conversions to open in either group. Estimated blood loss, length of stay, and complication rates were comparable. Operative time was shorter in the robotic versus laparoscopic group (130±8.94 vs. 159±11.1 min, P=0.0487). In follow-up, the improvement in patients' blood pressure after adrenalectomy, as assessed by the reduction in the number of antihypertensive medications, was similar between the 2 groups. However, 1 patient in the RA and 1 patient in the LA group were not cured, as determined by postoperative aldosterone:renin levels. The biochemical cure rate between the groups was similar (P=0.529). To our knowledge, this is the first study comparing robotic versus laparoscopic resection of PHA. Our results show that the robotic approach was similar to laparoscopic regarding safety and efficacy. Operative time was shorter with the robotic approach, which could be related to more efficient dissection with wristed instrumentation.

Robotic surgery has evolved from simple extirpative surgery to complex reconstructions even in infants. Data are lacking comparing surgical and direct costs to open approaches. We describe the feasibility, salient tips and outcomes of robot-assisted laparoscopic pyeloplasty compared to an open approach. We evaluated patients undergoing open pyeloplasty or robot-assisted laparoscopic pyeloplasty. Ten patients in each group met inclusion criteria. Mean patient age was 3.31 months in the open group and 7.3 months in the robotic group (p=0.02). Postoperative outcomes including length of stay (2.2 vs 2.1 days), estimated blood loss (6.5 vs 7.6 ml), days to regular diet (1 vs 1.1) and days to Foley catheter removal (1.3 vs 1.3) were similar between the open and robotic groups. Total operating time (199 vs 242 minutes) was significantly longer in the robotic group. Postoperative improvement in hydronephrosis was identical in both groups. Direct costs, excluding amortization, robotic cost, maintenance and depreciation, were $4,410 in the open group and $4,979 in the robotic group (p=0.10). In our preliminary experience robotic pyeloplasty in infants is feasible and safe. The immediate outcomes are similar to those of an open approach. The robotic technique in infants currently has the benefits of improved esthetic appearance, improved pain control and similar direct costs compared to the traditional open approach.

No criteria define indications for laparoscopic splenectomy in trauma. This investigation compared characteristics of trauma patients and outcomes between laparoscopic and open splenectomies. Patients were identified retrospectively by using ICD-9 codes. Included patients were 18 or older, with a blunt splenic injury from January 1, 2011, through December 31, 2014, and required splenectomy. Excluded patients had penetrating trauma, successful nonoperative management, or successful embolization. Variables included demographics, presenting characteristics, injury severity scores, abdominal abbreviated injury scores, splenic injury grade, surgical indication and approach (open or laparoscopic), surgery length, intra-operative blood loss, transfusions, length of stay, complications, mortality, and discharge disposition. Forty-one patients underwent open splenectomy, and 11 underwent laparoscopic splenectomy. The mean age was 48.7 years, and men comprised the sample majority (36/52). The groups were well matched for age, abdominal injury scores, and admission vital signs. The open group had a significantly lower level of consciousness and more acidosis compared with the laparoscopic group. Most laparoscopic splenectomies were performed after failed nonoperative management or embolization. The indications for open splenectomy were a positive focused assessment with sonography for trauma and computed tomography results. Laparoscopic patients had significantly longer times between presentation and surgery and longer operations, but had significantly less blood loss and fewer transfusions compared with the open group. There were no differences in mortality, length of stay, complications, or discharge dispositions. Laparoscopic splenectomy is useful in patients with blunt trauma in whom conservative management produced no improvement and who do not have other injuries to preclude laparoscopy.

The advances in both video games and minimally invasive surgery have allowed many to consider the potential positive relationship between the two. This review aims to evaluate outcomes of studies that investigated the correlation between video game skills and performance in laparoscopic surgery. A systematic search was conducted on PubMed/Medline and EMBASE databases for the MeSH terms and keywords including "video games and laparoscopy," "computer games and laparoscopy," "Xbox and laparoscopy," "Nintendo Wii and laparoscopy," and "PlayStation and laparoscopy." Cohort, case reports, letters, editorials, bulletins, and reviews were excluded. Studies in English, with task performance as primary outcome, were included. The search period for this review was 1950 to December 2014. There were 57 abstracts identified: 4 of these were found to be duplicates; 32 were found to be nonrelevant to the research question. Overall, 21 full texts were assessed; 15 were excluded according to the Medical Education Research Study Quality Instrument quality assessment criteria. The five studies included in this review were randomized controlled trials. Playing video games was found to reduce error in two studies (P 0.002 and P 0.045). For the same studies, however, several other metrics assessed were not significantly different between the control and intervention group. One study showed a decrease in the time for the group that played video games (P 0.037) for one of two laparoscopic tasks performed. In the same study, however, when the groups were reversed (initial control group became intervention and vice versa), a difference was not demonstrated (P for peg transfer 1 - 0.465, P for cobra robe - 0.185). Finally, two further studies found no statistical difference between the game playing group and the control group's performance. There is a very limited amount of evidence to support that the use of video games enhances surgical simulation performance.

Background Adoption of the laparoscopic approach for colorectal cancer treatment has been slow owing to initial case study results suggesting high recurrence rates at port sites. The use of laparoscopic surgery for colorectal cancer still raises a number of concerns, particularly with the technique’s complexity, learning curve and longer duration. After exploring the scientific literature comparing open and laparoscopic surgery for the treatment of colorectal cancer with respect to oncologic efficacy and short-term outcomes, the Comité de l’évolution des pratiques en oncologie (CEPO) made recommendations for surgical practice in Quebec. Methods Scientific literature published from January 1995 to April 2012 was reviewed. Phase III clinical trials and meta-analyses were included. Results Sixteen randomized trials and 10 meta-analyses were retrieved. Analysis of the literature confirmed that for curative treatment of colorectal cancer, laparoscopy is not inferior to open surgery with respect to survival and recurrence rates. Moreover, laparoscopic surgery provides short-term advantages, including a shorter hospital stay, reduced analgesic use and faster recovery of intestinal function. However, this approach does require a longer operative time. Conclusion Considering the evidence, the CEPO recommends that laparoscopic resection be considered an option for the curative treatment of colon and rectal cancer; that decisions regarding surgical approach take into consideration surgeon experience, tumour stage, potential contraindications and patient expectations; and that laparoscopic resection for rectal cancer be performed only by appropriately trained surgeons who perform a sufficient volume annually to maintain competence.

The concept of reducing the number of transabdominal access ports has been criticized for violating basic tenets of traditional multiport laparoscopy. Potential benefits of reduced port surgery may include decreased pain, improved cosmesis, less hernia formation, and fewer wound complications. However, technical challenges associated with these access methods have not been adequately addressed by advancement in instrumentations. We describe our initial experience with the NovaTract™ Laparoscopic Dynamic Retractor. A retrospective review of all patients who underwent two-port laparoscopic cholecystectomy between 2013 and 2014 using the NovaTract retractor was performed. The patients were equally divided into three groups (Group A, B, C) based on the order of case performed. Eighteen consecutive patients underwent successful two-port laparoscopic cholecystectomy for symptomatic cholelithiasis. Mean age was 39.9 years and mean body mass index was 28.1 kg/m(2) (range 21-39.4). Overall mean operative time was 65 minutes (range 42-105), with Group A of 70 minutes, Group B of 65 minutes, and Group C of 58 minutes (P = .58). All cases were completed laparoscopically using the retraction system, without a need for additional ports or open conversion. No intra- or postoperative complications were seen. All patients were discharged on the same day of surgery. No mortality found in this series. The NovaTract laparoscopic dynamic retractor is safe and easy to use, which is reflected by acceptable operative time for a laparoscopic cholecystectomy using only two ports. The system allows surgical approach to mimic the conventional laparoscopic techniques, while eliminating or reducing the number of retraction ports.

2011-01-01

Full Text Available Purpose: The purpose of the study was two-fold. Firstly it was to assess the suitability for tubal recanalization and factors predicting successful laparoscopic recanalization. Secondly, it was to analyze the fertility outcomes and factors affecting the pregnancy rate following laparoscopic tubal recanalization. Materials and Methods: A retrospective chart review of prospectively followed-up 29 women at a tertiary care center seeking tubal sterilization reversal between May 2005 and February 2010 were included. Results: In 14 (48.3% women unilateral tubes were suitable and in only 3 women (10.3% bilateral tubes were suitable. All cases with laparoscopic tubal sterilization were suitable, whereas all cases with fimbriectomy were unsuitable for recanalization. In 6 (20.7% cases salphingostomy was performed as an alternative procedure to tubal reanastomosis. The overall pregnancy rate was 58.8%. In cases with sterilization by Pomeroy′s method, 4 out of 10 (40% conceived, whereas for laparoscopic tubal ligation cases 6 out of 7 (85.7% conceived (P=0.32. None of the patients with final tubal length <5 cm conceived (P=0.03. Comparing the age at recanalization, in women ≤30 years, 71.4% conceived, as compared with 50% when age of women was more than 30 years (P=0.37. Conclusions: The important factors determining the success of recanalization are technique of sterilization and the remaining length of the tube after recanalization. The gynecologist must use an effective technique of sterilization to minimize the failure rates, but at the same time, which causes minimal trauma, and aim at preserving the length of the tube so that reversal is more likely to be successful, should the patient′s circumstances change.

Full Text Available Introduction. Several studies have shown the feasibility and safety of both transperitoneal and posterior retroperitoneal approaches for single incision laparoscopic adrenalectomy, but none have compared the outcomes according to the left- or right-sided location of the adrenal glands. Materials and Methods. From 2009 to 2013, 89 patients who received LAMP (laparoscopic adrenalectomy through mono port were analyzed. The surgical outcomes attained using the transperitoneal approach (TPA and posterior retroperitoneal approach (PRA were analyzed and compared. Results and Discussion. On the right side, no significant differences were found between the LAMP-TPA and LAMP-PRA groups in terms of patient characteristics and clinicopathological data. However, outcomes differed in which LAMP-PRA group had a statistically significant shorter mean operative time (84.13 ± 41.47 min versus 116.84 ± 33.17 min; P=0.038, time of first oral intake (1.00 ± 0.00 days versus 1.21 ± 0.42 days; P=0.042, and length of hospitalization (2.17 ± 0.389 days versus 3.68 ± 1.38 days; P≤0.001, whereas in left-sided adrenalectomies LAMP-TPA had a statistically significant shorter mean operative time (83.85 ± 27.72 min versus 110.95 ± 29.31 min; P=0.002. Conclusions. We report that LAMP-PRA is more appropriate for right-sided laparoscopic adrenalectomies due to anatomical characteristics and better surgical outcomes. For left-sided laparoscopic adrenalectomies, however, we propose LAMP-TPA as a more suitable method.

LAPAROSCOPIC PANCREATIC RESECTION. FROM ENUCLEATION TO PANCREATODUODENECTOMY. 11-YEAR EXPERIENCE

Full Text Available Context Our experience with laparoscopic pancreatic resection began in 2001. During initial experience, laparoscopy was reserved for selected cases. With increasing experience more complex laparoscopic procedures such as central pancreatectomy and pancreatoduodenectomies were performed. Objectives The aim of this paper is to review our personal experience with laparoscopic pancreatic resection over 11-year period. Methods All patients who underwent laparoscopic pancreatic resection from 2001 through 2012 were reviewed. Preoperative data included age, gender, and indication for surgery. Intraoperative variables included operative time, bleeding, blood transfusion. Diagnosis, tumor size, margin status were determined from final pathology reports. Results Since 2001, 96 patients underwent laparoscopic pancreatectomy. Median age was 55 years old. 60 patients were female and 36 male. Of these, 88 (91.6% were performed totally laparoscopic; 4 (4.2% needed hand-assistance, 1 robotic assistance. Three patients were converted. Four patients needed blood transfusion. Operative time varied according type of operation. Mortality was nil but morbidity was high, mainly due to pancreatic fistula (28.1%. Sixty-one patients underwent distal pancreatectomy, 18 underwent pancreatic enucleation, 7 pylorus-preserving pancreatoduodenectomies, 5 uncinate process resection, 3 central and 2 total pancreatectomies. Conclusions Laparoscopic resection of the pancreas is a reality. Pancreas sparing techniques, such as enucleation, resection of uncinate process and central pancreatectomy, should be used to avoid exocrine and/or endocrine insufficiency that could be detrimental to the patient's quality of life. Laparoscopic pancreatoduodenectomy is a safe operation but should be performed in specialized centers by highly skilled laparoscopic surgeons.

Full Text Available Background: Single-incision laparoscopic surgery (SILS has gained great popularity in paediatric surgery due to its minimally invasive approach and improved cosmetic results. Notwithstanding, reports describing its adoption in children are still fragmentary and some perplexities have been raised by some surgeons. We reviewed our experience with the SILS Palomo varicocelectomy procedure (SIL-V in children and adolescents, comparing this group with a similar series operated using conventional laparoscopic varicocelectomy (CL-V. Patients and Methods: A total of 69 Palomo laparoscopic varicocelectomies were performed in patients aged 11-17 years from January 2011 to January 2013. Indications for surgery included grades II-III varicocele or ipsilateral testicular hypotrophy. The SIL-V procedure was performed in 44 patients with roticulating and conventional 5 mm instruments. Testicular vessels were isolated "en bloc," clipped and cut. Operating time, visual analogue scale and post-operative results were compared to a similar group of 25 patients operated with CL-V. Results: No patient of the SIL-V group required conversion to conventional laparoscopy, none to open surgery. Mean operative time was 22 min (range: 19-28 in the SIL-V group, not significantly different compared with CL-V (mean 21 min, range: 18-25. All patients experienced a smooth recovery from surgery without any complications, and were discharged on day 1. No difficulties were found in the SIL-V group. The post-operative pain score was significantly better in SIL-V. Conclusion: The SIL-V procedure is safe and effective and allows a fast and efficient isolation of the vascular bundle. The use of conventional instruments is technically feasible in SIL-V.

Laparoscopic cholecystectomy, a minimal access surgery, is fast replacing open cholecystectomy and is being associated with less trauma. The objective of this study was to compare the proinflammatory cytokine levels in both laparoscopic cholecystectomy and open cholecystectomy. This study was carried out at Aseer Central Hospital, Aseer region, Abha Private Hospital and the College of Medicine and Medical Sciences, King Khalid University, Abha, Kingdom of Saudi Arabia, during the time period October 1998 through to November 2000. Sixty-one patients were included in the study, 27 of them had laparoscopic cholecystectomy and 34 had open cholecystectomy. Cytokines [Interleukin-6 Interleukin-1b, Tumor necrosis factor -a and Interleukin- 8] were measured in blood samples collected from the patients before, at and 24 hours post surgery, using commercially available kits. Interleukin-6 levels were significantly increased at 24 hours post surgery in the open cholecystectomy group of patients compared to the laparoscopic cholecystectomy group (P<0.04). No differences were found in the other cytokines levels (Interleukin-1b, tumor necrosis factor -a and Interleukin-8) between the open cholecystectomy and laparoscopic cholecystectomy groups. Laparoscopic cholecystectomy, a minimal access surgery, is associated with lower levels of the proinflammatory interleukin-6 cytokine compared to open cholecystectomy. (author)

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

Full Text Available The role of laparoscopy in the acute care surgery had significantly increased during the latest years, both as a diagnostic and treatment method of all the upper or lower gastrointestinal pathologies. The objective of the present research is to review the current indications for laparoscopy in bdominal emergencies and to detail the benefits and complications associated with this approach. We have reviewed the relevant literature about this topic published between January 2005 and December 2017, using the PubMed/Medline and Web of Science Core Collection databases. According to the current evidence, we may conclude that the laparoscopic approach is an integral part of the emergency surgery for all the abdominal pathologies. Although laparoscopy requires specialized training and curricula, it brings all the benefits of minimal access in acute care arena.

To analyze the financial implications of establishing a hysteroscopic sterilization program using the Essure micro-insert tubal sterilization system in an ambulatory clinic. A retrospective cohort study (Canadian Task Force classification Type II-2), in an ambulatory women's health clinic in a tertiary hospital, of 108 women undergoing Essure coil insertion between 2005 and 2006, and 104 women undergoing laparoscopic tubal sterilization for permanent sterilization between 2001 and 2004. The Essure procedures used a 4 mm single channel operative hysteroscope and conscious sedation (fentanyl and midazolam); the laparoscopic tubal sterilizations were completed under general anaesthesia with a 7 mm laparoscope and either bipolar cautery or Filshie clips. Costs associated with the procedure, follow-up, and management of any complications (including nursing, hospital charges, equipment, and disposables) were tabulated. The Essure coils were successfully placed on the first attempt in 103 of 108 women (95%). Three patients required a second attempt to complete placement and two patients required laparoscopic tubal sterilization after an unsuccessful Essure. All 104 laparoscopic tubals were completed on the first attempt with no complications reported. The total cost for the 108 Essure procedures, including follow-up evaluation, was $138,996 or $1287 per case. The total cost associated with the 104 laparoscopic tubal sterilization procedures was $148,227 or $1398 per case. The incremental cost-effectiveness ratio was $111. The Essure procedure in an ambulatory setting resulted in a statistically significant cost saving of $111 per sterilization procedure. Carrying out the Essure procedure in an ambulatory setting frees space in the operating room for other types of cases, improving access to care for more patients.

Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery). We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004. We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt für Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie. Handsearch of abstracts from the following society meetings from 1991 to 2004: American College of Surgeons, American Society of Colorectal Surgeons, Royal Society of Surgeons, British Assocation of Coloproctology, Surgical Association of Endoscopic Surgeons, European Association of Endoscopic Surgeons, Asian Society of Endoscopic Surgeons. All randomised-controlled trial were included regardless of the language of publication. No- or pseudorandomised trials as well as studies that followed patient's preferences towards one of the two interventions were excluded, but listed separately. RCT presented as only an abstract were excluded. Results were extracted from papers by three observers independently on a predefined data sheet. Disagreements were solved by discussion. 'REVMAN 4.2' was used for statistical analysis. Mean differences (95% confidence intervals) were used for analysing continuous variables. If

Full Text Available Background: Percutaneous endoscopic gastrostomy (PEG and laparoscopic-assisted gastrostomy (LAG are widely used in the paediatric population. The aim of this study was to determine which one of the two procedures is the most effective and safe method. Methods: This systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses statement. Primary outcomes were success rate, efficacy of feeding, quality of life, gastroesophageal reflux and post-operative complications. Results: Five retrospective studies, comparing 550 PEG to 483 LAG placements in children, were identified after screening 2347 articles. The completion rate was similar for both procedures. PEG was associated with significantly more adjacent bowel injuries (P = 0.047, early tube dislodgements (P = 0.02 and complications that require reintervention under general anaesthesia (P < 0.001. Minor complications were equally frequent after both procedures. Conclusions: Because of the lack of well-designed studies, we have to be cautious in making definitive conclusions comparing PEG to LAG. To decide which type of gastrostomy placement is best practice in paediatric patients, randomised controlled trials comparing PEG to LAG are highly warranted.

To describe the laparoscopic approach for uretero-ileal anastomosis strictures and to analyse our long term series. A retrospective review was performed evaluating our series of patients with benign ureteroileal anastomosis strictures treated laparoscopically from 2011 to 2017. Demographics and perioperative data were obtained and analyzed. Complications were described with the Clavien-Dindo classification. The surgical technique was described and a literature review was performed. Eleven procedures were performed in ten patients. Mean blood loss was 180 ml. All the operations were performed laparoscopically without conversion. Mean hospital stay was 10 days (4-23). Early complications were Clavien-Dindo I y II: Two cases of limited anastomosis leakage, one lymphorrea, one paralitic ileum and one accidental descent of the ureteral catheter. Mean follow-up was 56 months (12-179) No late complications have been described. Based on our series with 5 year follow up, the laparoscopic approach for uretero-ileal anastomosis strictures is feasible and safe.

The role of the da Vinci Robotic System ® in adrenal gland surgery is not yet well defined. The goal of this study was to compare robotic-assisted surgery with pure laparoscopic surgery in a single center. One hundred and 16 patients underwent minimally invasive adrenalectomies in our department between June 1994 and December 2014, 41 of whom were treated with a robotic-assisted approach (robotic adrenalectomy, RA). Patients who underwent RA were matched according to BMI, age, gender, and nodule dimensions, and compared with 41 patients who had undergone laparoscopic adrenalectomies (LA). Statistical analysis was performed using the Student's t test for independent samples, and the relationship between the operative time and other covariates were evaluated with a multivariable linear regression model.

Several recent studies have suggested that warming up prior to surgery may improve surgical performance. The purpose of this study was to investigate whether warming up prior to laparoscopic surgery improves surgical performance or reduces surgery duration. Between August 2011 and January 2012, a randomized controlled trial was conducted to compare two warm-up modalities to no warm-up. The study was conducted at a single site, with nine surgeons performing 72 laparoscopic cholecystectomies and 37 laparoscopic appendicectomies. Prior to surgery, surgeons were randomized to either laparoscopic trainer box warm-up, PlayStation 2 warm-up or no warm-up. The activity was performed within 30 min of surgery commencing. Patients provided informed consent for the surgery to be digitally recorded. Digital videodiscs (DVDs) were reviewed by an independent and blinded assessor. Data were collected on duration of surgery, level of training and perceived surgical difficulty. Surgical performance was graded using a validated scoring system. From the 109 operations performed, there were 75 usable DVDs. Overall, there were no statistical differences in the demographics of patients and surgeons in the three treatment groups, nor in the subset that had useable DVDs. There were no statistical differences in the duration of surgery or surgeon's perceived surgical difficulty. There was no statistical difference in surgical performance. This study suggests that warm-up prior to laparoscopic cholecystectomy or appendicectomy is not essential, acknowledging that there are several study limitations that preclude definitive conclusion. © 2012 The Authors.

Full Text Available Objective: Most laparoscopic surgeons have attempted to reduce incisional morbidity and improve cosmetic outcomes by using less and smaller trocars. Single incision laparoscopic splenectomy is a new laparoscopic procedure. Herein we would like to present our experiences.Material and Methods: Between January 2009 and June 2009, data of the 7 patients who underwent single incision laparoscopic splenectomy were evaluated retrospectively.Results: There were 7 patients (5 females and 2 males with a mean age of 29.9 years. The most common splenectomy indication was idiopathic thrombocytopenic purpura. Single incision laparoscopic splenectomy was performed successfully in 6 patients. In one patient the operation was converted to an open procedure.Conclusion: With surgeons experienced in minimally invasive surgery, single incision laparoscopic splenectomy could be performed successfully. However, in order to demonstrate the differneces between standard laparoscopic splenectomy and SILS splenetomy, prospective randomized comparative studies are required.

This study was designed to compare spinal anesthesia using hyperbaric bupivacaine given as a conventional dose by lumbar puncture or as a low-dose by thoracic puncture.Methods: A total of 140 patients with symptomatic gallstone disease were randomized to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under spinal anesthesia using either conventional lumbar spinal anesthesia (hyperbaric bupivacaine 15 mg and fentanyl 20 mg or low-dose thoracic spinal anesthesia (hyperbaric bupivacaine 7.5 mg and fentanyl 20 µg. Intraoperative parameters, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two treatment groups.Results: All procedures were completed under spinal anesthesia, with no cases needing conversion to general anesthesia. Values for time for block to reach the T3 dermatomal level, duration of motor and sensory block, and hypotensive events were significantly lower with low-dose bupivacaine. Postoperative pain was higher for low-dose hyperbaric bupivacaine at 6 and 12 hours. All patients were discharged after 24 hours. Follow-up 1 week postoperatively showed all patients to be satisfied and to be keen advocates of spinal anesthesia.Conclusion: Laparoscopic cholecystectomy can be performed successfully under spinal anesthesia. A small dose of hyperbaric bupivacaine 7.5 mg and 20 µg fentanyl provides adequate spinal anesthesia for laparoscopy and, in comparison with hyperbaric bupivacaine 15% and fentanyl 20 µg, causes markedly

Transversus abdominis plane (TAP) block using a short-acting local anesthetic as part of multimodal analgesia is efficient in various abdominal surgeries, including laparoscopic surgery. However, information regarding its use in laparoscopic colorectal surgery is still limited and sometimes controversial. Therefore, we conducted a systematic review and meta-analysis to determine whether TAP block using a short-acting anesthetic has a positive postoperative analgesic outcome in patients who have undergone laparoscopic colorectal surgery. We searched for studies comparing the postoperative pain outcome after laparoscopic colorectal surgery between patients who received TAP block and a control group (placebo or no treatment). Outcome measures were early pain at rest (numeric rating scale [NRS] score at 0-2 h postoperatively), late pain at movement (NRS score at 24 h postoperatively), late pain at rest (NRS score at 24 h postoperatively), and postoperative opioid consumption (up to 24 h postoperatively). We used a random-effects model for the meta-analysis and Egger's regression test to detect publication bias. We included six studies involving 452 patients (224 in the TAP block group, 228 in the control group). Early and late pain scores at movement were significantly different between the TAP block and control groups (standardized mean difference: - 0.695, P consumption (P = 0.257). The TAP block using a short-acting anesthetic had a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) period at movement. However, it did not have a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) periods at rest after laparoscopic surgery.

Laparoscopy is the most common procedure for correction of congenital pyloric stenosis. The standard laparoscopic approach is based on the three-port technique. In contrast to the standard laparoscopic technique, the single-incision laparoscopic surgery (SILS) requires only one incision. We report on our experience with this surgical approach. Between September 2009 and August 2010 a total of 24 children underwent a laparoscopic pyloromyotomy, 12 in SILS technique. The single incision was carried through the center of the umbilicus. The working instruments were introduced in a two-dimensional direction into the peritoneal cavity via the same umbilical incision. The two groups were compared for patients' demographics, operative report and early postoperative outcomes. All SILS procedures were performed successfully with no conversion rate. There were no differences in the preoperative parameters between the two groups regarding age before surgery and body weight at operation. Operative time and time of full enteral intake was similar to comparable procedures with usage of a standard laparoscopic approach. There were no operative or postoperative complications. The early experience described in this study confirms that SILS can be applied for treatment of pyloric stenosis with outcomes similar to the standard laparoscopic surgery.

Transverse colon malignancies have been excluded from all randomized controlled trials comparing laparoscopic against open colectomies, potentially due to the advanced laparoscopic skills required for dissecting around the middle colic vessels and the associated morbidity. Concerns have been expressed that the laparoscopic approach may compromise the oncological clearance in transverse colon cancer. This study aimed to comprehensively compare the laparoscopic (LPA) to the open (OPA) approach by performing a meta-analysis of long and short term outcomes. Medline, Embase, Cochrane library, Scopus and Web of Knowledge databases were interrogated. Selected studies were critically appraised and the short-term morbidity and long term oncological outcomes were meta-analyzed. Sensitivity analysis according to the quality of the study, type of procedure (laparoscopic vs laparoscopically assisted) and level of lymphadenectomy was performed. Statistical heterogeneity and publication bias were also investigated. Eleven case control trials (1415 patients) were included in the study. There was no difference between the LPA and the OPA in overall survival [Hazard Ratio (HR) = 0.83 (0.56, 1.22); P = 0.34], disease free survival (p = 0.20), local recurrence (p = 0.81) or distant metastases (p = 0.24).

Laparoscopy was a progressive step to advancing surgical procedures as it minimised the scars left on the body after surgery, compared to traditional open surgery. Many years later, single-incision laparoscopic surgery (SILS) was created where, instead of having multiple incisions, only one incision is made or multiple small incisions in one location. SILS, or laparoendoscopic single-site surgery (LESS), may produce lesser scars but drawbacks for the surgeons are still present. This paper aims to present related literature of the recent technological developments in laparoscopic tools and procedure particularly in the vision system, handheld instruments. Tech advances in LESS will also be shown. Furthermore, this review intends to give an update on what has been going on in the surgical robot market and state which companies are interested and are developing robotic systems for commercial use to challenge Intuitive Surgical's da Vinci Surgical System that currently dominates the market.

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

The continuing evolution of technique and devices used in laparoscopic liver resection (LLR) has allowed successful application of this minimally invasive surgery for the treatment of liver disease. However, the type of instruments by energy sources and technique used vary among each institution. We reviewed the literature to seek the best technique for parenchymal transection, which was proposed as one of the important clinical question in the 2nd International Consensus Conference on LLR held on October 2014. While publications have described transection techniques used in LLR from 1991 to June 2014, it is difficult to specify the best technique and device for laparoscopic hepatic parenchymal transection, owing to a lack of randomized trials with only a small number of comparative studies. However, it is clear that instruments should be used in combination with others based on their functions and the depth of liver resection. Most authors have reported using staplers to secure and divide major vessels. Preparation for prevention of unexpected hemorrhaging particularly in liver cirrhosis, the Pringle's maneuver and prompt technique for hemostasis should be performed. We conclude that hepatobiliary surgeons should select techniques based on their familiarity with a concrete understanding of instruments and individualize to the procedure of LLR. © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Since 2010, comparative studies on transanal and laparoscopic total mesorectal excision (TME) have been published and it remains unclear about the oncological benefit from transanal total mesorectal excision (taTME). We have searched English databases to identify all taTME studies published between January 2010 and August 2017. Pathological outcomes included circumferential resection margin (CRM), positive CRM (CRM (WMD, 0.833; 95% CI 0.366-1.299; P CRM (OR, 0.505; 95% CI 0.258-0.991; P = 0.047), and a longer DRM (WMD, 6.261; 95% CI 1.049-11.472; P = 0.019). There were no significant differences in other pathological outcomes. Both cumulative meta-analysis and sensitivity analysis were unable to detect potential sources of the heterogeneity in DRM. There was no evidence of publication bias. This meta-analysis revealed that taTME had more advantages on positive CRM, CRM, and DRM compared with laparoscopic TME. Compared with laparoscopic TME, more benefits of taTME on pathological outcomes remained undetected. The current findings are all based on observational studies, RCTs with adequate power are required.

Full Text Available Purpose: One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. Materials and Methods: With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. Results: This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024. Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS. No difference was noted in the postoperative pain scores. Conclusion: Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

Secrets of safe laparoscopic surgery: Anaesthetic and surgical considerations

2010-01-01

Full Text Available In recent years, laparoscopic surgery has gained popularity in clinical practice. The key element in laparoscopic surgery is creation of pneumoperitoneum and carbon dioxide is commonly used for insufflation. This pneumoperitoneum perils the normal cardiopulmonary system to a considerable extent. Every laparoscopic surgeon should understand the consequences of pneumoperitoneum; so that its untoward effects can be averted. Pneumoperitoneum increases pressure on diaphragm, leading to its cephalic displacement and thereby decreasing venous return, which can be aggravated by the position of patient during surgery. There is no absolute contraindication of laparoscopic surgery, though we can anticipate some problems in conditions like obesity, pregnancy and previous abdominal surgery. This review discusses some aspects of the pathophysiology of carbon dioxide induced pneumoperitoneum, its consequences as well as strategies to counteract them. Also, we propose certain guidelines for safe laparoscopic surgery.

Full Text Available Abstract Background Several systematic reviews and meta-analyses populate the literature on the effectiveness of laparoscopic surgery for colorectal cancer. The utility of this body of work is unclear. The objective of this study was to synthesize all such systematic reviews in terms of clinical effectiveness, to appraise their quality, and to determine whether areas of duplication exist across reviews. Methods Systematic reviews comparing laparoscopic and open surgery for colorectal cancer were identified using a comprehensive search protocol (1991 to 2008. The primary outcome was overall survival. The methodological quality of reviews was appraised using the Assessment of Multiple Systematic Reviews (AMSTAR instrument. Abstraction and quality appraisal was carried out by two independent reviewers. Reviews were synthesized, and outcomes were compared qualitatively. A citation analysis was carried out using simple matrices to assess the comprehensiveness of each review. Results In total, 27 reviews were included; 13 reviews included only randomized controlled trials. Rectal cancer was addressed exclusively by four reviews. There was significant overlap between review purposes, populations and, outcomes. The mean AMSTAR score (out of 11 was 5.8 (95% CI: 4.6 to 7.0. Overall survival was evaluated by ten reviews, none of which found a significant difference. Three reviews provided a selective meta-analysis of time-to-event data. Previously published systematic reviews were poorly and highly selectively referenced (mean citation ratio 0.16, 95% CI: 0.093 to 0.22. Previously published trials were not comprehensively identified and cited (mean citation ratio 0.56, 95% CI: 0.46 to 0.65. Conclusions Numerous overlapping systematic reviews of laparoscopic and open surgery for colorectal cancer exist in the literature. Despite variable methods and quality, survival outcomes are congruent across reviews. A duplication of research efforts appears to exist

Full Text Available Background: Severe abdominal pain is not common after laparoscopic surgeries, but acute or chronic pain after operation is considerable in some patients. Post-operative Pain control after laparoscopic surgeries, is conventionally achieved using analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs and narcotics, but their administration has a lot of side effects. This study compares the efficacy and side effects of local anesthetic drugs versus conventional analgesics in post-operative pain control.Materials and Methods: This prospective investigation was conducted into two groups of patients (n=93. Group 1, as control group, was given conventional analgesics such as narcotics and NSAIDs. In investigational group, at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (Lidocaine 2% plus a long acting (Bupivacaine 0.5% is instilled through the port lumen between the abdominal wall layers. The efficacy of both types of medications was compared to their efficacy and side effects.Results: 85% of the control group, received 5 to 20 ml Morphine for pain control while the others were controlled with trans-rectal NSAIDs. In the treatment group, the pain of 65% of the patients was controlled only by local anesthetic drugs, 30% required NSAIDs and the other 5% required narcotics administration for pain control.Conclusion: The administration of local anesthetic drugs after laparoscopic surgery is an effective method for pain control with a low complications rate and side effects of narcotics.

The management of gastrointestinal malignancies continues to evolve with the latest available therapeutic and diagnostic modalities. There are currently two driving forces in the management of these cancers: the benefits of minimally invasive surgery so thoroughly demonstrated by laparoscopic surgery, and the shift toward neoadjuvant chemotherapy for upper gastrointestinal cancers. In order to match the appropriate treatment to the disease, accurate staging is imperative. No technological advances have combined these two needs as much as laparascopic ultrasound to evaluate the liver and peritoneal cavity. We present a concise review of the latest application of laparoscopic ultrasound in management of gastrointestinal malignancy.

The laparoscopic repair of Morgagni's hernia (MH) has been reported to be safe and feasible. However, it is still unclear whether laparoscopy is superior to open surgery in repairing MH. Using a defined search strategy, three investigators independently identified all comparative studies reporting data on open and laparoscopic MH repair in patients open approaches and 39 (42%) laparoscopy. Meta-analysis - The length of surgery was shorter in laparoscopy (50.5 ± 17.0 min) than in open procedure (90.0 ± 15.0 min; P open surgery (4.5 ± 2.1 days; P open: 9.4% ± 1.6%; P = .087) and recurrences (laparoscopy: 2.9% ± 5.0%, open: 5.7% ± 1.8%; P = .84). Comparative studies indicate that laparoscopic MH repair can be performed in infants and children. Laparoscopy is associated with shortened length of surgery and hospital stay in comparison to open procedure. Prospective randomized studies would be needed to confirm present data.

Laparoscopic use of laser and monopolar electrocautery

Science.gov (United States)

Hunter, John G.

1991-07-01

Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

Laparoscopic bariatric surgery has experienced a rapid expansion of interest over the past 5 years, with a 470% increase. This rapid expansion has markedly increased overall cost, reducing surgical access. Many surgeons believe that the traditional open approach is a cheaper, safer, equally effective alternative. 16 highly experienced "open" bariatric surgeons with a combined total of 25,759 cases representing >200 surgeon years of experience, pooled their open Roux-en-Y gastric bypass (ORYGBP) data, and compared their results to the leading laparoscopic (LRYGBP) papers in the literature. In the overall series, the incisional hernia rate was 6.4% using the standard midline incision. Utilizing the left subcostal incision (LSI), it was only 0.3%. Return to surgery in <30 days was 0.7%, deaths 0.25%, and leaks 0.4%. Average length of stay was 3.4 days, and return to usual activity 21 days. Small bowel obstruction was significantly higher with the LRYGBP. Surgical equipment costs averaged approximately $3,000 less for "open" cases. LRYGBP had an added expense for longer operative time. This more than made up for the shorter length of stay with the laparoscopic approach. The higher cost, higher leak rate, higher rate of small bowel obstruction, and similar long-term weight loss results make the "open" RYGBP our preferred operation. If the incision is taken out of the equation (i.e. use of the LSI), the significant advantages of the open technique become even more obvious.

To report about an additional case of biliary ileus after bariatric surgery is reported and extensively reviewing the literature on this topic. We reviewed the literature and found three cases of gallstone ileus (GI) that occurred after bariatric surgery. A 41 year old patient presented a GI eight years after a biliointestinal bypass (BIB) for morbid obesity. The patient complained of abdominal pain for two weeks. Computed tomography (CT) and abdominal ultrasound (US) allowed a preoperative diagnosis of GI and planning of surgical strategy. Surgical treatment was carried out through laparoscopic-assisted enterolithotomy alone procedure. This choice is supported discussing the related issues: morbidity, potential recurrence, eventual developing of gallbladder carcinoma. It is the first reported case of GI after BIB preoperatively diagnosed through CT scan and US, and treated with a laparoscopic assisted approach. Additional considerations concerning preoperative diagnosis, surgical strategy, technical details and follow-up can be usefully applied even in non post-bariatric biliary ileus.

Transversus abdominis plane (TAP) block is a locoregional anaesthesia technique of growing interest in abdominal surgery. However, its efficacy following laparoscopic colorectal surgery is still debated. This meta-analysis aimed to assess the efficacy of TAP block after laparoscopic colorectal surgery. All comparative studies focusing on TAP block after laparoscopic colorectal surgery have been systematically identified through the MEDLINE database, reviewed and included. Meta-analysis was performed according to the Mantel-Haenszel method for random effects. End-points included postoperative opioid consumption, morbidity, time to first bowel movement and length of hospital stay. A total of 13 studies, including 7 randomized controlled trials, were included, comprising a total of 600 patients who underwent laparoscopic colorectal surgery with TAP block, compared with 762 patients without TAP block. Meta-analysis of these studies showed that TAP block was associated with a significantly reduced postoperative opioid consumption on the first day after surgery [weighted mean difference (WMD) -14.54 (-25.14; -3.94); P = 0.007] and a significantly shorter time to first bowel movement [WMD -0.53 (-0.61; -0.44); P plane (TAP) block in laparoscopic colorectal surgery improves postoperative opioid consumption and recovery of postoperative digestive function without any significant drawback.

Laparoscopic managment of common bile duct stones: our initial experience.

Science.gov (United States)

Aroori, S; Bell, J C

2002-05-01

The management of choledocholithiasis has changed radically since the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones laparoscopically at the time of cholecystectomy. This has lead to reliance on endoscopic retrograde cholangiopancreatography followed by endoscopic sphincterotomy to deal with common bile duct stones. We retrospectively reviewed the charts of patients who had laparoscopic common bile duct exploration at Downe Hospital between December 1999 and August 2001. Among 149 laparoscopic cholecystectomies done by our group in this period, 10 patients (6.7%) underwent laparoscopic CBD exploration, three by the transcystic technique and seven by choledochotomy. Three patients (2%) had unsuspected stones found on routine per- operative cholangiogram. The mean operative time was 2.34hrs (range 1.50-3.30hrs). The mean hospital post- operative stay was 3 days (range 1-6 days). Post-operative morbidity was zero. Stone clearance was achieved in all cases. We conclude, laparoscopic exploration of the common bile duct is relatively safe and straightforward method. The key skill required is the ability to perform laparoscopic suturing with confidence.

Laparoscopic surgery (LS) has proved superior compared to conventional surgery (CS) regarding morbidity, length of hospital stay, rate of wound infection and time until recovery. An improved preservation of the postoperative immune function is assumed to contribute to these benefits though the role of the local peritoneal immune response is still poorly understood. Our study investigates the peritoneal immune response subsequent to abdominal surgery and compares it between laparoscopic and conventional surgery to find an immunological explanation for the clinically proven benefits of LS. Wistar rats (N = 140) underwent laparoscopic cecum resection (LCR; N = 28), conventional cecum resection (CCR; N = 28), laparoscopic sham operation (LSO; N = 28), conventional sham operation (CSO; N = 28), or no surgical treatment (CTRL; N = 28). Postoperatively, peritoneal lavages were performed, leukocytes isolated and analyzed regarding immune function and phagocytosis activity. Immune function was inhibited postoperatively in animals undergoing LCR or CCR compared to CTRL reflected by a lower TNF-α (CTRL 3956.65 pg/ml, LCR 2018.48 pg/ml (p = 0.023), CCR 2793.78 pg/ml (n.s.)) and IL-6 secretion (CTRL 625.84 pg/ml, LCR 142.84 pg/ml (p = 0.009), CCR 169.53 pg/ml (p = 0.01)). Phagocytosis was not affected in rats undergoing any kind of surgery compared to CTRL. Neither cytokine secretion nor phagocytosis activity differed significantly between laparoscopic and conventional surgery. According to our findings the benefits associated with LS compared to CS cannot be explained by differences in the postoperative peritoneal innate immune response. Further studies are needed to elucidate the causes for a more favorable postoperative outcome in patients after LS compared to CS.

Do laparoscopic skills transfer to robotic surgery?

Panait, Lucian; Shetty, Shohan; Shewokis, Patricia A; Sanchez, Juan A

2014-03-01

Identifying the set of skills that can transfer from laparoscopic to robotic surgery is an important consideration in designing optimal training curricula. We tested the degree to which laparoscopic skills transfer to a robotic platform. Fourteen medical students and 14 surgery residents with no previous robotic but varying degrees of laparoscopic experience were studied. Three fundamentals of laparoscopic surgery tasks were used on the laparoscopic box trainer and then the da Vinci robot: peg transfer (PT), circle cutting (CC), and intracorporeal suturing (IS). A questionnaire was administered for assessing subjects' comfort level with each task. Standard fundamentals of laparoscopic surgery scoring metric were used and higher scores indicate a superior performance. For the group, PT and CC scores were similar between robotic and laparoscopic modalities (90 versus 90 and 52 versus 47; P > 0.05). However, for the advanced IS task, robotic-IS scores were significantly higher than laparoscopic-IS (80 versus 53; P robotic-PT score when compared with laparoscopic-PT (92 versus 105; P  0.05). The robot was favored over laparoscopy for all drills (PT, 66.7%; CC, 88.9%; IS, 94.4%). For simple tasks, participants with preexisting skills perform worse with the robot. However, with increasing task difficulty, robotic performance is equal or better than laparoscopy. Laparoscopic skills appear to readily transfer to a robotic platform, and difficult tasks such as IS are actually enhanced, even in subjects naive to the technology. Copyright © 2014 Elsevier Inc.

2012-09-12

The role of a robotic assistant in laparoscopic cholecystectomy is controversial. While some trials have shown distinct advantages of a robotic assistant over a human assistant others have not, and it is unclear which robotic assistant is best. The aims of this review are to assess the benefits and harms of a robot assistant versus human assistant or versus another robot assistant in laparoscopic cholecystectomy, and to assess whether the robot can substitute the human assistant. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded (until February 2012) for identifying the randomised clinical trials. Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing robot assistants versus human assistants in laparoscopic cholecystectomy were considered for the review. Randomised clinical trials comparing different types of robot assistants were also considered for the review. Two authors independently identified the trials for inclusion and independently extracted the data. We calculated the risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI) using the fixed-effect and the random-effects models based on intention-to-treat analysis, when possible, using Review Manager 5. We included six trials with 560 patients. One trial involving 129 patients did not state the number of patients randomised to the two groups. In the remaining five trials 431 patients were randomised, 212 to the robot assistant group and 219 to the human assistant group. All the trials were at high risk of bias. Mortality and morbidity were reported in only one trial with 40 patients. There was no mortality or morbidity in either group. Mortality and morbidity were not reported in the remaining trials. Quality of life or the proportion of patients who were discharged as day-patient laparoscopic cholecystectomy patients were not reported in any

Acute appendicitis (AA) in elderly patients (60 years of age and older) is a challenging problem associated with significant morbidity and mortality when perforation is present. We hypothesized that laparoscopic appendectomy (LA) would enable an earlier correct diagnosis and have advantages in elderly patients. We performed a retrospective review of patients who underwent laparoscopic appendectomy for suspected AA. Data of elderly patients were compared to data of younger patients (18 to <60 years of age). Fifty-four LA were performed in elderly patients and 423 in younger patients. Patients over the age of 60 years had more co-morbidities and required more frequent use of anticoagulants. Preoperative imaging (ultrasound or computerized tomography) was significantly more frequent in elderly patients (36% versus 15%), and was associated with a higher rate of confirmation of acute appendicitis (78% versus 55%), which allowed a decrease in the rate of negative surgical explorations to 4.1% in elderly patients compared to 10.2% in younger patients. Complicated appendicitis and conversions were more frequent in the elderly patients. This resulted in prolonged operative time and longer hospital stay for this group. The overall complication rate was equivalent in the two groups, without differences in the occurrence either of infectious complications or of complications related to surgical site. There were no deaths following appendectomy in our series. Laparoscopic appendectomy is safe in the elderly population and is not associated with any increase in morbidity. The high incidence of complicated appendicitis in elderly patients affects operative time and length of hospital stay following laparoscopic appendectomy, and it can also lead to an increased rate of conversion to an open procedure. Use of preoperative abdominal computerized tomography scan is mandatory in elderly patients to provide an early diagnosis and to decrease unnecessary surgical exploration when acute

With recent advances in minimally invasive techniques, many surgeons are favoring laparoscopic over traditional "open" pyloromyotomy for hypertrophic pyloric stenosis. The results of few studies, however, exist in the literature adequately comparing surgical outcome. We present a retrospective analysis of 56 consecutive patients who underwent laparoscopic or open pyloromyotomy. A retrospective chart review of 56 consecutive infants (ages: 2 to 9 weeks; weights: 2.2 to 5.4 kilograms) who underwent laparoscopic (Group A-28) vs open (Group B- 28) pyloromyotomy between January 2000 and May 2001 was performed. Preoperative (age, sex, weight, HCO3, and K values) and postoperative (operating time, time to full feedings, persistence of emesis, and hospital stay) parameters were compared. Statistical analysis was performed via the Student t test and chi-square/Fischer analysis where appropriate. A P value 0.05). In Group A, 26/28 (92.9%) were completed successfully with 2 open conversions. Group A versus Group B average operating times (36.1 vs 32.5 minutes), time to full feedings (24.1 vs 27.0 hours), and hospital stay (2.5 vs 2.6 days) were similar (P>0.05). Persistent vomiting was observed in Group A, 25.0% (day 1)/3.5% (day 2) vs Group B, 39.3% (day 1)/10.7% (day 2). One infant in Group B required operative drainage of a wound abscess 1 week after surgery. Laparoscopic pyloromyotomy can be performed with similar efficiency and surgical outcome as traditional open pyloromyotomy. Improved cosmesis and avoidance of wound complications are major benefits of this procedure, and a tendency towards less postoperative emesis is a potential benefit that deserves further investigation.

Anastomotic leakage (AL) is one of the most dreadful postoperative complications because it can result in increased morbidity and mortality as well as poorer long-term prognosis. Although most studies of AL limited their investigation time to a period of 30 days postoperatively, only a few studies have shown that AL can occur after that period. Here, we report four patients of rectal cancer with delayed AL following laparoscopic intersphincteric resection (ISR) and conduct a literature review on delayed AL. Case 1 was a 67-year-old male who underwent laparoscopic partial ISR in July 2009. Although the patient was asymptomatic, an anastomotic-urethral fistula was observed 57 months after ISR. Case 2 was a 44-year-old female who underwent laparoscopic partial ISR in July 2008. She presented with discharge of gas and feces from her vagina, and an anastomotic-vaginal fistula was observed 14 months after ISR. Case 3 was a 74-year-old man who underwent laparoscopic partial ISR in August 2007. He presented with pneumaturia and fecaluria, and an anastomotic-urethral fistula was observed 4 months after ISR. Case 4 was a 68-year-old woman who underwent laparoscopic subtotal ISR for rectal cancer in February 2013 and partial hepatic resection for liver metastases in March 2013. She presented with anal pain and purulent perineal discharge, and an anastomotic-perineal fistula was observed 9 months after ISR. All four cases presented with fistula formation and required reoperation (establishment of a diverting ileostomy). Since delayed AL is not a rare postoperative complication, surgeons need to provide long-term follow-up and remain alert to the possible development of delayed AL.

Full Text Available Transumbilical laparoscopic assisted appendectomy combines laparoscopic single port dissection with open appendectomy after exteriorization of the appendix through the port site. Compared to the conventional three-port approach, this technique provides an alternative with excellent cosmetic outcome. We developed a safe and effective technique to perform an intracorporeal single port appendectomy, using the same laparoscope employed in the extracorporeal procedure. Retrospective review of 71 consecutively performed intracorporeal single port appendectomies and 30 conventional three-port appendectomies in children 6 to 17 years of age. A straight 10-mm Storz telescope with inbuilt 6 mm working channel is used to dissect the appendix, combined with one port-less 2.3 mm percutaneous grasper. Polymer WECK® hem-o-lock® clips are applied to seal the base of the appendix and the appendiceal vessels. No intraoperative complications were reported with the hybrid intracorporeal single port appendectomy or three-port appendectomy. There were two post-operative complications in the group treated with the single port hybrid technique: one intra-abdominal abscess and one surgical site infection. Groups did not differ in age, weight, and types of appendicitis. Operative times were shorter for the hybrid technique (70 vs 79 minutes but did not differ significantly (P=0.19. This modified technique to a previously described single port extracorporeal appendectomy is easy to master and implement. It provides exposure similar to a three-port laparoscopic appendectomy, while maintaining virtually scarless results and potentially reduces the risk for surgical site infections compared to the extracorporeal technique.

Full Text Available Abstract Background Rectovaginal fistula (RVF is an epithelium-lined communication between the rectum and vagina. Most RVFs are acquired, the most common cause being obstetric trauma. Most of the high RVFs are repaired by conventional open surgery. Laparoscopic repair of RVF is rare and so far only one report is available in the literature. Methods We present a case of high RVF repaired by laparoscopy. 56-year-old female who had a high RVF following laparoscopic assisted vaginal hysterectomy was successfully operated laparoscopically. Here we describe the operative technique and briefly review the literature. Results The postoperative period of the patient was uneventful and after a follow up of 6 months no recurrence was found. Conclusion Laparoscopic repair of high RVF is feasible in selected patients but would require proper identification of tissue planes and good laparoscopic suturing technique.

Radiofrequency has been used as a tool for liver resection since 2002. A new laparoscopic device is reported in this article that assists liver resection laparoscopically. From October 2006 to the present, patients suitable for liver resection were assessed carefully for laparoscopic resection with the laparoscopic Habib Sealer (LHS). Detailed data of patients resected laparoscopically with this device were collected prospectively and analyzed. In all, 28 patients underwent attempted laparoscopic liver resection. Four cases had to be converted to an open approach because of extensive adhesions from previous colonic operations. Twenty-four patients completed the procedure comprising tumorectomy (n = 7), multiple tumoretcomies (n = 5), segmentectomy (n = 3), and bisegmentectomies (n = 9). Vascular clamping of portal triads was not used. The mean resection time was 60 +/- 23 min (mean +/- SD), and blood loss was 48 +/- 54 mL. None of the patients received any transfusion of blood or blood products perioperatively or postoperatively. Postoperatively, 1 patient developed severe exacerbation of asthma that required steroid therapy, and 1 other patient had a transient episode of liver failure that required supportive care. The mean duration of hospital stay was 5.6 +/- 2 days (mean +/- SD). At a short-term follow up, no recurrence was detected in patients with liver cancer. Laparoscopic liver resection can be performed safely with this new laparoscopic liver resection device with a significantly low risk of intraoperative bleeding or postoperative complications.

To compare surgical outcomes between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy in patients with chronic kidney disease. Of 550 patients who underwent partial nephrectomy between 2012 and 2015, 163 patients with T1-2 renal tumors who had an estimated glomerular filtration rate between 30 and 60 mL/min/1.73 m 2 , and underwent robot-assisted laparoscopic partial nephrectomy or open partial nephrectomy were retrospectively analyzed. To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching. The present study included 75 patients undergoing robot-assisted laparoscopic partial nephrectomy and 88 undergoing open partial nephrectomy. After propensity score matching, 40 patients were included in each operative group. The mean preoperative estimated glomerular filtration rate was 49 mL/min/1.73 m 2 . The mean ischemia time was 21 min in robot-assisted laparoscopic partial nephrectomy (warm ischemia) and 35 min in open partial nephrectomy (cold ischemia). Preservation of the estimated glomerular filtration rate 3-6 months postoperatively was not significantly different between robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy (92% vs 91%, P = 0.9348). Estimated blood loss was significantly lower in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (104 vs 185 mL, P = 0.0025). The postoperative length of hospital stay was shorter in the robot-assisted laparoscopic partial nephrectomy group than in the open partial nephrectomy group (P negative surgical margin status were not significantly different between the two groups. In our experience, robot-assisted laparoscopic partial nephrectomy and open partial nephrectomy provide similar outcomes in terms of functional preservation and perioperative complications among patients with chronic kidney disease. However, a lower estimated blood loss and

Since it's introduction, laparoscopic surgery represented a real revolution in clinical practice. The use of a new generation three-dimensional (3D) HD laparoscopic system can be considered a favorable "hybrid" made by combining two different elements: feasibility and diffusion of laparoscopy and improved quality of vision. In this study we report our clinical experience with use of three-dimensional (3D) HD vision system for laparoscopic surgery. Between 2013 and 2017 a prospective cohort study was conducted at the University Hospital of Palermo. We considered 163 patients underwent to laparoscopic three-dimensional (3D) HD surgery for various indications. This 3D-group was compared to a retrospective-prospective control group of patients who underwent the same surgical procedures. Considerating specific surgical procedures there is no significant difference in term of age and gender. The analysis of all the groups of diseases shows that the laparoscopic procedures performed with 3D technology have a shorter mean operative time than comparable 2D procedures when we consider surgery that require complex tasks. The use of 3D laparoscopic technology is an extraordinary innovation in clinical practice, but the instrumentation is still not widespread. Precisely for this reason the studies in literature are few and mainly limited to the evaluation of the surgical skills to the simulator. This study aims to evaluate the actual benefits of the 3D laparoscopic system integrating it in clinical practice. The three-dimensional view allows advanced performance in particular conditions, such as small and deep spaces and promotes performing complex surgical laparoscopic procedures.

The utility of laparoscopic repair in the treatment of incisional hernia repair is still contentious. The aim was to conduct a meta-analysis of RCTs investigating the surgical and postsurgical outcomes of elective incisional hernia by open versus laparoscopic method. A search of PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane Central Register of Controlled Trials published between January 1993 and September 2013 was performed using medical subject headings (MESH) "hernia," "incisional," "abdominal," "randomized/randomised controlled trial," "abdominal wall hernia," "laparoscopic repair," "open repair", "human" and "English". Prospective RCTs comparing surgical treatment of only incisional hernia (and not primary ventral hernias) using open and laparoscopic methods were selected. Data extraction and critical appraisal were carried out independently by two authors (AA and MAM) using predefined data fields. The outcome variables analyzed included (a) hernia diameter; (b) operative time; (c) length of hospital stay; (d) overall complication rate; (e) bowel complications; (f) reoperation; (g) wound infection; (h) wound hematoma or seroma; (i) time to oral intake; (j) back to work; (k) recurrence rate; and (l) postoperative neuralgia. These outcomes were unanimously decided to be important since they influence the practical and surgical approach towards hernia management within hospitals and institutions. The quality of RCTs was assessed using Jadad's scoring system. Random effects model was used to calculate the effect size of both binary and continuous data. Heterogeneity amongst the outcome variables of these trials was determined by the Cochran Q statistic and I (2) index. The meta-analysis was prepared in accordance with PRISMA guidelines. Sufficient data were available for the analysis of twelve clinically relevant outcomes. Statistically significant reduction in bowel complications was noted with open surgery compared to the

Laparoscopic surgery carries the advantage of minimal invasiveness, but ergonomic design of the instruments used has progressed slowly. Previous studies have demonstrated that the handle of laparoscopic instruments is vital for both surgical performance and surgeon's health. This review provides an overview of the sub-discipline of handle ergonomics, including an evaluation framework, objective and subjective assessment systems, data collection and statistical analyses. Furthermore, a framework for ergonomic research on laparoscopic instrument handles is proposed to standardize work on instrument design. Copyright © 2016 IJS Publishing Group Ltd.

To compare the surgical outcomes 12 months after laparoscopic sacrocolpopexy performed with porcine dermis and the current gold standard of polypropylene mesh. Patients scheduled for laparoscopic sacrocolpopexy were eligible for this randomized controlled trial. Both our clinical research nurse and the patients were blinded as to which material was used. Our primary end point was objective anatomic cure defined as no pelvic organ prolapse quantification (POP-Q) points Stage 2 or greater at any postoperative interval. Our sample size calculation called for 57 patients in each group to achieve 90% power to detect a 23% difference in objective anatomic cure at 12 months (α=0.05). Our secondary end point was clinical cure. Any patient with a POP-Q point greater than zero, or Point C less than or equal to -5, or any complaints of prolapse symptoms whatsoever on Pelvic Floor Distress Inventory-20 or Pelvic Floor Impact Questionnaire, Short Form 7, or reoperation for prolapse were considered "clinical failures"; the rest were "clinical cures." Statistical comparisons were performed using the χ or independent samples t test as appropriate. As expected, there were no preoperative differences between the porcine (n=57) and mesh (n=58) groups. The 12-month objective anatomic cure rates for the porcine and mesh groups were 80.7% and 86.2%, respectively (P=.24), and the "clinical cure" rates for the porcine and mesh groups were 84.2% and 89.7%, respectively (P=.96). Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire, Short Form 7 score improvements were significant for both groups with no differences found between groups. There were no major operative complications. There were similar outcomes in subjective or objective results 12 months after laparoscopic sacrocolpopexy performed with either porcine dermis or polypropylene mesh.

What is going on in augmented reality simulation in laparoscopic surgery?

Botden, Sanne M B I; Jakimowicz, Jack J

2009-08-01

To prevent unnecessary errors and adverse results of laparoscopic surgery, proper training is of paramount importance. A safe way to train surgeons for laparoscopic skills is simulation. For this purpose traditional box trainers are often used, however they lack objective assessment of performance. Virtual reality laparoscopic simulators assess performance, but lack realistic haptic feedback. Augmented reality (AR) combines a virtual reality (VR) setting with real physical materials, instruments, and feedback. This article presents the current developments in augmented reality laparoscopic simulation. Pubmed searches were performed to identify articles regarding surgical simulation and augmented reality. Identified companies manufacturing an AR laparoscopic simulator received the same questionnaire referring to the features of the simulator. Seven simulators that fitted the definition of augmented reality were identified during the literature search. Five of the approached manufacturers returned a completed questionnaire, of which one simulator appeared to be VR and was therefore not applicable for this review. Several augmented reality simulators have been developed over the past few years and they are improving rapidly. We recommend the development of AR laparoscopic simulators for component tasks of procedural training. AR simulators should be implemented in current laparoscopic training curricula, in particular for laparoscopic suturing training.

Robotic platforms have the potential advantage of providing additional dexterity and precision to surgeons while performing complex laparoscopic tasks, especially for those in training. Few quantitative evaluations of surgical task performance comparing laparoscopic and robotic platforms among surgeons of varying experience levels have been done. We compared measures of quality and efficiency of Fundamentals of Laparoscopic Surgery task performance on these platforms in novices and experienced laparoscopic and robotic surgeons. Fourteen novices, 12 expert laparoscopic surgeons (>100 laparoscopic procedures performed, no robotics experience), and five expert robotic surgeons (>25 robotic procedures performed) performed three Fundamentals of Laparoscopic Surgery tasks on both laparoscopic and robotic platforms: peg transfer (PT), pattern cutting (PC), and intracorporeal suturing. All tasks were repeated three times by each subject on each platform in a randomized order. Mean completion times and mean errors per trial (EPT) were calculated for each task on both platforms. Results were compared using Student's t-test (P task performance was slower on the robotic platform compared with laparoscopy. In comparisons of expert laparoscopists performing tasks on the laparoscopic platform and expert robotic surgeons performing tasks on the robotic platform, expert robotic surgeons demonstrated fewer errors during the PC task (P = 0.009). Robotic assistance provided a reduction in errors at all experience levels for some laparoscopic tasks, but no benefit in the speed of task performance. Robotic assistance may provide some benefit in precision of surgical task performance. Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate the clinical advantages of single-port laparoscopic hepatectomy (SPLH) compare to multi-port laparoscopic hepatectomy (MPLH). We retrospectively reviewed the medical records of 246 patients who underwent laparoscopic liver resection between January 2008 and December 2015 at our hospital. We divided the surgical technique into two groups; SPLH and MPLH. We performed laparoscopic liver resection for both benign and malignant disease. Major hepatectomy such as right and left hepatectomy was also done with sufficient disease-free margin. The operative time, the volume of blood loss, transfusion rate, and the conversion rate to MPLH or open surgery was evaluated. The post-operative parameters included the meal start date after operation, the number of postoperative days spent in the hospital, and surgical complications was also evaluated. Of the 246 patients, 155 patients underwent SPLH and 91 patients underwent MPLH. Conversion rate was 22.6% in SPLH and 19.8% in MPLH ( P = 0.358). We performed major hepatectomy, which was defined as resection of more than 2 sections, in 13.5% of patients in the SPLH group and in 13.3% of patients in the MPLH group ( P = 0.962). Mean operative time was 136.9 ± 89.2 min in the SPLH group and 231.2 ± 149.7 min in the MPLH group ( P started earlier in the SPLH group (1.06 ± 0.27 d after operation) than in the MPLH group (1.63 ± 1.27 d) ( P < 0.001). The mean hospital stay after operation was non-significantly shorter in the SPLH group than in the MPLH group (7.82 ± 2.79 d vs 7.97 ± 3.69 d, P = 0.744). The complication rate was not significantly different ( P = 0.397) and there was no major perioperative complication or mortality case in both groups. Single-port laparoscopic liver surgery seems to be a feasible approach for various kinds of liver diseases.

Laparoscopic herniorrhaphy.

Swanstrom, L L

1996-06-01

There is little doubt that laparoscopic herniorrhaphy has assumed a place in the pantheon of hernia repair. There is also little doubt that further work needs to be done to determine the exact role that laparoscopic hernia repair should play in the surgical armamentarium. Hernias have been surgically treated since the early Greeks. In contrast, laparoscopic hernia repair has a history of only 6 years. Even within that short time, laparoscopic hernia repair techniques have not remained unchanged. This is obviously a technique in evolution, as indicated by the abandonment of early repairs ("plug and mesh" and IPOM) and the gradual gain in pre-eminence of the TEP repair. During the same time frame, surgery itself has evolved into a discipline more concerned with cost-effectiveness, outcomes, and "consumer acceptance." Confluence of these two developments has led to a situation in which traditional concerns regarding surgical procedures (i.e., recurrence rates or complication rates) assume less of a role than cost-effectiveness, learnability, marketability, and medical-legal considerations. No surgeon, whether practicing in a academic setting or a private practice, is exempt from these pressures. Laparoscopic hernia repair therefore seems to fit into a very specialized niche. In our community, the majority of general surgeons are only too happy to not do laparoscopic hernia repairs. On the other hand, in our experience, certain indications do seem to cry out for a laparoscopic approach. At our own center we have found that laparoscopic repairs can indeed be effective, and even cost-effective, under specific circumstances. These include completing a minimal learning curve, utilizing the properitoneal approach, minimizing the use of reusable instruments, using dissecting balloons as a time-saving device, and very specific patient selection criteria. At present these include patients with bilateral inguinal hernias on clinical examination, patients with recurrent

Bariatric surgery makes up an increasing percentage of general surgery training. The safety of resident involvement in these complex cases has been questioned. We evaluated patient outcomes in resident performed laparoscopic bariatric procedures. Retrospective review of patients undergoing a laparoscopic bariatric procedure over seven years at a tertiary care single center. Procedures were primarily performed by a general surgery resident and proctored by an attending surgeon. Primary outcomes included operative volume, operative time and leak rate with perioperative outcomes evaluated as secondary outcomes. A total of 1649 bariatric procedures were evaluated. Operations included laparoscopic bypass (690) and laparoscopic sleeve gastrectomy (959). Average operating time was 136 min. Eighteen leaks (0.67%) were identified. Graduating residents performed an average of 89 laparoscopic bariatric cases during their training. There were no significant differences between resident levels with concern to operative time or leak rate (p 0.97 and p = 0.54). General surgery residents can safely perform laparoscopic bariatric surgery. When proctored by a staff surgeon, a resident's level of training does not significantly impact leak rate.

Thromboelastography (TEG) is a technique that measures coagulation processes and surveys the properties of a viscoelastic blood clot, from its formation to lysis. To determine the possible hypercoagulability state and the effect of antithrombotic prophylaxis on thromboelastogram results and development of venous thrombosis during laparoscopic fundoplication. The study was performed on 106 patients who were randomized into two groups. The first group received low-molecular-weight heparin (LMWH) 12 h before the operation, and 6 and 30 h after it. The second group received LMWH only 1 h before the laparoscopic fundoplication. The TEG profile was collected before LMWH injection, 1 h after the introduction of the laparoscope and 15 min after the surgery was completed. There was no significant difference in thromboelastography R-time between the groups before low-molecular-weight heparin injection. In group I preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, after the end of surgery and on the third postoperative day. K-time values decreased significantly on the third postoperative day compared with the results before low-molecular-weight heparin injection, and after the operation. In group II, preoperative R-values significantly decreased 1 h after the introduction of the laparoscope, and after surgery. K-time values did not change significantly during or after the laparoscopic operation. Our study results demonstrated that the hypercoagulation state (according to the TEG results) was observed during and after laparoscopic fundoplication in patients when LMWH was administered 12 h before the operation together with intraoperative intermittent pneumatic compression. The optimal anticoagulation was obtained when LMWH was administered 1 h before fundoplication.

Full Text Available Introduction: Laparoscopic cholecystectomy has clearly become the choice over open cholecystectomy in the treatment of hepatobiliary disease since its introduction by Mouret in 1987. This study evaluates a series of patients with chronic calculus cholecystitis who were treated with laparoscopic and open cholecystectomy and assesses the outcomes of both techniques. Objective: To evaluate the efficacy of laparoscopic vs open cholecystectomy in chronic calculus cholecystitis and establish the out-comes of this treatment modality at Lumbini Medical College and Teaching Hospital. Methods: This was a retrospective analysis over a one-year period (January 1, 2012 to December 31, 2012, per-formed by single surgeon at Lumbini Medical College and Teaching Hospital located midwest of Nepal. 166 patients underwent surgical treatment for chronic calculus cholecystitis. Patients included were only chronic calculus cholecystitis proven histopathologocally and the rest were excluded. Data was collected which included patients demographics, medical history, presentation, complications, conversion rates from laparoscopic. cholecystectomy to open cholecystectomy, operative and postoperative time. Results: Patients treated with laparoscopic cholecystectomy for chronic calculus cholecystitis had shorter operating times and length of stay compared to patients treated with open cholecystectomy for chronic calculus cholecystitis. Conversion rates were 3.54% in chronic calculus cholecystitis during the study period. Complications were also lower in patients who underwent laparoscopic cholecystectomy versus open cholecystectomy for cholelithiasis. Conclusions: Laparoscopic cholecystectomy appears to be a reliable, safe, and cost-effective treatment modality for chronic calculus cholecystitis.

Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

There is increasing awareness of potential ergonomic challenges experienced by the laparoscopic surgeon. The purpose of this study is to quantify and compare the ergonomic stress experienced by a surgeon while performing open versus laparoscopic portions of a procedure. We hypothesize that a surgeon will experience greater ergonomic stress when performing laparoscopic surgery. We designed a study to measure upper-body muscle activation during the laparoscopic and open portions of sigmoid colectomies in a single surgeon. A sample of five cases was recorded over a two-month time span. Each case contained significant portions of laparoscopic and open surgery. We obtained whole-case electromyography (EMG) tracings from bilateral biceps, triceps, deltoid, and trapezius muscles. After normalization to a maximum voltage of contraction (%MVC), these EMG tracings were used to calculate average muscle activation during the open and laparoscopic segments of each procedure. Paired Student's t test was used to compare the average muscle activation between the two groups (*p open procedures were noted for the left triceps (4.07 ± 0.44% open vs. 2.65 ± 0.54% lap, 35% reduction), left deltoid (2.43 ± 0.45% open vs. 1.32 ± 0.16% lap, 46% reduction), left trapezius (9.93 ± 0.1.95% open vs. 4.61 ± 0.67% lap, 54% reduction), right triceps (2.94 ± 0.62% open vs. 1.85 ± 0.28% lap, 37% reduction), and right trapezius (10.20 ± 2.12% open vs. 4.69 ± 1.18% lap, 54% reduction). Contrary to our hypothesis, the laparoscopic approach provided ergonomic benefit in several upper-body muscle groups compared to the open approach. This may be due to the greater reach of laparoscopic instruments and camera in the lower abdomen/pelvis. Patient body habitus may also have less of an effect in the laparoscopic compared to open approach. Future studies with multiple subjects and different types of procedures are planned to further investigate these findings.

Laparoscopic suturing is an advanced skill that is difficult to acquire. Simulator-based skills curricula have been developed that have been shown to transfer to the operating room. Currently available skills curricula need to be optimized. We hypothesized that mastering basic laparoscopic skills first would shorten the learning curve of a more complex laparoscopic task and reduce resource requirements for the Fundamentals of Laparoscopic Surgery suturing curriculum. Medical students (n = 20) with no previous simulator experience were enrolled in an IRB-approved protocol, pretested on the Fundamentals of Laparoscopic Surgery suturing model, and randomized into 2 groups. Group I (n = 10) trained (unsupervised) until proficiency levels were achieved on 5 basic tasks; Group II (n = 10) received no basic training. Both groups then trained (supervised) on the Fundamentals of Laparoscopic Surgery suturing model until previously reported proficiency levels were achieved. Two weeks later, they were retested to evaluate their retention scores, training parameters, instruction requirements, and cost between groups using t-test. Baseline characteristics and performance were similar for both groups, and 9 of 10 subjects in each group achieved the proficiency levels. The initial performance on the simulator was better for Group I after basic skills training, and their suturing learning curve was shorter compared with Group II. In addition, Group I required less active instruction. Overall time required to finish the curriculum was similar for both groups; but the Group I training strategy cost less, with a savings of $148 per trainee. Teaching novices basic laparoscopic skills before a more complex laparoscopic task produces substantial cost savings. Additional studies are needed to assess the impact of such integrated curricula on ultimate educational benefit. Copyright (c) 2010 American College of Surgeons. Published by Elsevier Inc.

The fundamental idea is to have all of the laparoscopic working ports entering the abdominal wall through the same incision. Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus and reduces morbidity of minimally invasive surgery. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. This review summarizes the history of SPAL hysterectomy (single-port access laparoscopy), and emphasizes nomenclature, surgical technique, instrumentation, and perioperative outcomes. Specific gynecological applications of single-port hysterectomy to date are summarized. Using the PubMed database, the English-language literature was reviewed for the past 40 years. Keyword searches included scarless, scar free, single-port/trocar/incision, single-port access laparoscopic hysterectomy. Within the bibliography of selected references, additional sources were retrieved. The purpose of the present article was to review the development and current status of SPAL hysterectomy and highlight important advances associated with this innovative approach.

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

The management of gallbladder stones (lithiasis) concomitant with bile duct stones is controversial. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. The laparoscopic-endoscopic rendezvous combines the two techniques in a single-stage operation. To compare the benefits and harms of endoscopic sphincterotomy and stone removal followed by laparoscopic cholecystectomy (the single-stage rendezvous technique) versus preoperative endoscopic sphincterotomy followed by laparoscopic cholecystectomy (two stages) in people with gallbladder and common bile duct stones. We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, Science Citation Index Expanded Web of Science, and two trials registers (February 2017). We included randomised clinical trials that enrolled people with concomitant gallbladder and common bile duct stones, regardless of clinical status or diagnostic work-up, and compared laparoscopic-endoscopic rendezvous versus preoperative endoscopic sphincterotomy procedures in people undergoing laparoscopic cholecystectomy. We excluded other endoscopic or surgical methods of intraoperative clearance of the bile duct, e.g. non-aided intraoperative endoscopic retrograde cholangiopancreatography or laparoscopic choledocholithotomy (surgical incision of the common bile duct for removal of bile duct stones). We used standard methodological procedures recommended by Cochrane. We included five randomised clinical trials with 517 participants (257 underwent a laparoscopic-endoscopic rendezvous technique versus 260 underwent a sequential approach), which fulfilled our inclusion criteria and provided data for analysis. Trial participants were scheduled for laparoscopic cholecystectomy because of suspected cholecysto-choledocholithiasis. Male/female ratio was 0.7; age of men and women ranged from 21 years to 87

Laparoscopic common bile duct exploration (CBDE) is becoming more popular in the management of choledocholithiasis due to improved laparoscopic expertise and advancement in endoscopic technology and equipment. This study aimed to evaluate the safety and short-term outcome of laparoscopic CBDE in a single institution over a 3-year period. A retrospective review of the records of all patients who underwent laparoscopic CBDE in Tan Tock Seng Hospital between January 2006 and September 2008 was conducted. Fifty consecutive patients, with a median age of 60 years (range, 27 to 85) underwent laparoscopic CBDE for choledocholithiasis during the study period. About half of our patients presented as an emergency with acute cholangitis (32.0%) accounting for the majority. A total of 22 (44.0%) patients underwent laparoscopic CBDE as their primary procedure while the remaining 28 (56.0%) were subjected to preoperative ERCP initially. Of the latter group, documented stone clearance was only documented in 5 (17.9%) patients. Laparoscopic CBDE via the transcystic route was performed in 27 (54.0%) patients while another 18 patients (36.0%) had laparoscopic choledochotomy and 1 patient (2.0%) had laparoscopic choledocho-duodenostomy. There were 4 (8.0%) conversions in our series. The median operative time for laparoscopic CBDE via the transcystic route and the laparoscopic choledochotomy were 170 (75-465) and 250 (160-415) minutes, respectively. For the 18 patients who underwent a laparoscopic choledochotomy, T-tube was inserted in 8 (44.4%) patients while an internal biliary stent was placed in 4 (22.2%) with the remaining 6 patients (33.3%) undergoing primary closure of the choledochotomy. The median length of hospital stay was 2 days (range, 1 to 15) with no associated mortality. The main complications (n = 4, 8.0%) included retained CBD stones and biliary leakage. These were treated successfully with postoperative endoscopic retrograde cholangiopancreatography (ERCP) with

Traditionally, laparoscopic cholecystectomy is performed using two 10-mm ports and two 5-mm ports. Recently, a reduction in the number of ports has been suggested as a modification of the standard technique with a view to decreasing pain and improving cosmesis. The safety and effectiveness of using fewer-than-four ports has not yet been established. To assess the benefits (such as improvement in cosmesis and earlier return to activity) and harms (such as increased complications) of using fewer-than-four ports (fewer-than-four-ports laparoscopic cholecystectomy) versus four ports in people undergoing laparoscopic cholecystectomy for any reason (symptomatic gallstones, acalculous cholecystitis, gallbladder polyp, or any other condition). We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 8, 2013), MEDLINE, EMBASE, Science Citation Index Expanded, and the World Health Organization International Clinical Trials Registry Platform portal to September 2013. We included all randomised clinical trials comparing fewer-than-four ports versus four ports, that is, with standard laparoscopic cholecystectomy that is performed with two ports of at least 10-mm incision and two ports of at least 5-mm incision. Two review authors independently identified the trials and extracted the data. We analysed the data using both the fixed-effect and the random-effects models. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis, whenever possible. We found nine trials with 855 participants that randomised participants to fewer-than-four-ports laparoscopic cholecystectomy (n = 427) versus four-port laparoscopic cholecystectomy (n = 428). Most trials included low anaesthetic risk participants undergoing elective laparoscopic cholecystectomy. Seven of the nine trials used a single port laparoscopic cholecystectomy and the remaining two trials used three-port laparoscopic

Laparoscopic colectomies, with and without robotic assistance, are performed to treat both benign and malignant colonic disease. This study compared clinical and economic outcomes for laparoscopic colectomy procedures with and without robotic assistance. Patients aged ≥18 years having primary inpatient laparoscopic colectomy procedures (cecectomy, right hemicolectomy, left hemicolectomy, and sigmoidectomy) identified by International Classification of Diseases, Ninth Edition procedure codes performed between 2009 and the second quarter of 2011 from the Premier Hospital Database were studied. Patients were matched to a control cohort using propensity scores for disease, comorbidities, and hospital characteristics and were matched 1:1 for specific colectomy procedure. The outcomes of interest were hospital cost of laparoscopic robotic-assisted colectomy compared with traditional laparoscopic colectomy, surgery time, adverse events, and length of stay. Of 25,758 laparoscopic colectomies identified, 98% were performed without robotic assistance and 2% were performed with robotic assistance. After matching, 1066 patients remained, 533 in each group. Lengths of stay were not significantly different between the matched cohorts, nor were rates of major, minor, and/or surgical complications. Inpatient procedures with robotic assistance were significantly more costly than those without robotic assistance ($17,445 vs $15,448, P = .001). Operative times were significantly longer for robotic-assisted procedures (4.37 hours vs 3.34 hours, P < .001). Segmental colectomies can be performed safely by either laparoscopic or robotic-assisted methods. Increased per-case hospital costs for robotic-assisted procedures and prolonged operative times suggest that further investigation is warranted when considering robotic technology for routine laparoscopic colectomies.

Report of our initial experience in laparoscopic hysterectomy by a solo surgeon using a robotic camera system with three-dimensional visualisation. This novel device (Einstein Vision®, B. Braun, Aesculap AG, Tuttlingen, Germany) (EV) was used for laparoscopic supracervical hysterectomy (LASH) performed by one surgeon. Demographic data, clinical and surgical parameters were evaluated. Our first 22 cases, performed between June and November 2012, were compared with a cohort of 22 age-matched controls who underwent two-dimensional LASH performed by the same surgeon with a second surgeon assisting. Compared to standard two-dimensional laparoscopic hysterectomy, there were no significant differences regarding duration of surgery, hospital stay, blood loss or incidence of complications. The number of trocars used was significantly higher in the control group (p solo surgery laparoscopic hysterectomy is a feasible and safe procedure. Duration of surgery, hospital stay, blood loss, and complication rates are comparable to a conventional laparoscopic hysterectomy.

Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but unfortunately there are no guidelines for annotating these videos or agreed methods to measure the educational content and the safety of the procedure presented. Aim of this study is to systematically search the World Wide Web to determine the availability of laparoscopic colorectal surgery videos and to objectively establish their potential training value. A search for laparoscopic right hemicolectomy videos was performed on the three most used English language web search engines Google.com, Bing.com, and Yahoo.com; moreover, a survey among 25 local trainees was performed to identify additional websites for inclusion. All laparoscopic right hemicolectomy videos with an English language title were included. Videos of open surgery, single incision laparoscopic surgery, robotic, and hand-assisted surgery were excluded. The safety of the demonstrated procedure was assessed with a validated competency assessment tool specifically designed for laparoscopic colorectal surgery and data on the educational content of the video were extracted. Thirty-one websites were identified and 182 surgical videos were included. One hundred and seventy-three videos (95%) detailed the year of publication; this demonstrated a significant increase in the number of videos published per year from 2009. Characteristics of the patient were rarely presented, only 10 videos (5.4%) reported operating time and only 6 videos (3.2%) reported 30-day morbidity; 34 videos (18.6%) underwent a peer-review process prior to publication. Formal case presentation, the presence of audio narration, the use of diagrams, and snapshots and a step-by-step approach are all characteristics of peer-reviewed videos but no significant difference was found in the safety of the procedure. Laparoscopic videos can be a useful adjunct to operative training. There is a large and increasing amount of

A meta-analysis of published literature comparing outcomes after laparoscopic resection (LR) with open resection (OR) for transverse colon tumours. Medline, PubMed, CINAHL, EMBASE and Cochrane were searched from inception to October 2013. The text words "minimally invasive", "keyhole surgery" and "transverse colon" were used in combination with the medical subject headings "laparoscopy" and "colon cancer". Outcome variables were chosen based upon whether the included articles reported results. A meta-analysis was performed to obtain a summative outcome. Six comparatives involving 444 patients were analysed. Of them 245 patients were in the LR group and 199 in the OR group. There was a significant increase in operative time in the LR group compared with the OR group [random effects model: SMD = -0.65, 95% CI (-1.01, -0.30), z = -3.60, p transverse colon tumours is a safe and effective technique. Although there is an increase in operating time, operative and clinical outcomes of intraoperative blood loss and faster recovery are seen with laparoscopic procedures.

In recent years the progress of laparoscopic procedures and the development of new and dedicated technologies have made laparoscopic hepatic surgery feasible and safe. In spite of this laparoscopic liver resection remains a surgical procedure of great challenge because of the risk of massive bleeding during liver transection and the complicated biliary and vascular anatomy in the liver. A new laparoscopic device is reported here to assist liver resection laparoscopically. The laparoscopic Habib 4X is a bipolar radiofrequency device consisting of a 2 x 2 array of needles arranged in a rectangle. It is introduced perpendicularly into the liver, along the intended transection line. It produces coagulative necrosis of the liver parenchyma sealing biliary radicals and blood vessels and enables bloodless transection of the liver parenchyma. Twenty-four Laparoscopic liver resections were performed with LH4X out of a total of 28 attempted resections over 12 months. Pringle manoeuvre was not used in any of the patients. None of the patients required intraoperative transfusion of red cells or blood products. Laparoscopic liver resection can be safely performed with laparoscopic Habib 4X with a significantly low risk of intraoperative bleeding or postoperative complications.

The purpose of this study was to estimate the effects of surgical laparoscopic operation course on laparoscopic operation skills after the simulated training for medical students with relatively objective results via data gained before and after the practice course of laparoscopic simulator of the resident standardized trainees. Experiment 1: 20 resident standardized trainees with no experience in laparoscopic surgery were included in the inexperienced group and finished simulated cholecystectomy according to simulator videos. Simulator data was collected (total operation time, path length, average speed of instrument movement, movement efficiency, number of perforations, the time cautery is applied without appropriate contact with adhesions, number of serious complications). Ten attending doctors were included in the experienced group and conducted the operation of simulated cholecystectomy directly. Data was collected with simulator. Data of two groups was compared. Experiment 2: Participants in inexperienced group were assigned to basic group (receiving 8 items of basic operation training) and special group (receiving 8 items of basic operation training and 4 items of specialized training), and 10 persons for each group. They received training course designed by us respectively. After training level had reached the expected target, simulated cholecystectomy was performed, and data was collected. Experimental data between basic group and special group was compared and then data between special group and experienced group was compared. Results of experiment 1 showed that there is significant difference between data in inexperienced group in which participants operated simulated cholecystectomy only according to instructors' teaching and operation video and data in experienced group. Result of experiment 2 suggested that, total operation time, number of perforations, number of serious complications, number of non-cauterized bleeding and the time cautery is applied

Laparoscopic assistance is often entrusted to a less experienced resident, medical student, or operating room nurse. Data regarding laparoscopic training for operating room nurses are not available. The aim of the study was to analyse the initial performance level and learning curves of operating room nurses in basic laparoscopic surgery compared with medical students and surgical residents to determine their ability to assist with this type of procedure. The study was designed to compare the initial virtual reality performance level and learning curves of user groups to analyse competence in laparoscopic assistance. The study subjects were operating room nurses, medical students, and first year residents. Participants performed three validated tasks (camera navigation, peg transfer, fine dissection) on a virtual reality laparoscopic simulator three times in 3 consecutive days. Laparoscopic experts were enrolled as a control group. Participants filled out questionnaires before and after the course. Nurses and students were comparable in their initial performance (p>0.05). Residents performed better in camera navigation than students and nurses and reached the expert level for this task. Residents, students, and nurses had comparable bimanual skills throughout the study; while, experts performed significantly better in bimanual manoeuvres at all times (p<0.05). The included user groups had comparable skills for bimanual tasks. Residents with limited experience reached the expert level in camera navigation. With training, nurses, students, and first year residents are equally capable of assisting in basic laparoscopic procedures. Copyright © 2017 Elsevier Ltd. All rights reserved.

Laparoscopic radical cystectomy with lymphadenectomy and urinary diversion is an increasingly widespread operation. Studies are needed to support the oncological effectiveness and safety of this minimally invasive approach. A nonrandomised, comparative prospective study between open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) was conducted in a university hospital. The main objective was to compare cancer-specific survival. The secondary objective was to compare the surgical results and complications according to the Clavien-Dindo scale. We treated 156 patients with high-grade invasive bladder cancer with either ORC (n=70) or LRC (n=86). The mean follow-up was 33.5±23.8 (range 12-96) months. The mean age was 66.9+9.4 years, and the male to female ratio was 19:1. Both groups were equivalent in age, stage, positive lymph nodes, in situ carcinoma, preoperative obstructive uropathy, adjuvant chemotherapy and type of urinary diversion. There were no differences between the groups in terms of cancer-specific survival (log-rank; P=.71). The histopathology stage was the only independent variable that predicted the prognosis. The hospital stay (P=.01) and operative transfusion rates (P=.002) were less for LRC. The duration of the surgery was greater for LRC (P<.001). There were no differences in the total complications rate (p=.62) or major complications (P=.69). The risk of evisceration (P=.02), surgical wound infection (P=.005) and pneumonia (P=.017) was greater for ORC. The risk of rectal lesion (P=.017) and urethrorectal fistulae (P=.065) was greater for LRC. LRC is an equivalent treatment to ORC in terms of oncological efficacy and is advantageous in terms of transfusion rates and hospital stays but not in terms of operating room time and overall safety. Studies are needed to better define the specific safety profile for each approach. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

Full Text Available This review paper discusses the ergonomic challenges associated with laparoscopy in the operating room (OR and summarizes the practical ergonomic solutions. The literature search was conducted in the fields of laparoscopy and applied ergonomics. Findings indicated that laparoscopic OR staff (surgeons, perioperative nurses and technicians commonly experienced physical and mental ergonomic risks while working in prolonged static and awkward body positions. This study highlighted the need for more ergonomic interventions in OR environment in order to improve the efficiency of laparoscopy. Ergonomic solutions included utilizing adjustable equipment, placing computer peripherals in optimal locations, providing ergonomic instruments, and improving communication. Understanding the job- or task-related ergonomic risks and hazards could help identify intervention requirements to meet the challenges associated with increased dependency on advanced high technology in the OR.

The aim of this study is to compare the perioperative and oncologic outcomes of open and laparoscopic approaches for concomitant resection of synchronous colorectal cancer and liver metastases. Between 2006 and 2015, all patients undergoing combined resection of primary colorectal cancer and liver metastases were included in the study (n=43). Laparoscopic and open groups were compared regarding clinical, perioperative and oncologic outcomes. There were 29 patients in the open group and 14 patients in the laparoscopic group. The groups were similar regarding demographics, comorbidities, histopathological characteristics of the primary tumor and liver metastases. Postoperative complication rate (44.8% vs . 7.1%, P=0.016) was higher, and hospital stay (10 vs . 6.4 days, P=0.001) longer in the open compared to the laparoscopic group. Overall survival (OS) was comparable between the groups (P=0.10); whereas, disease-free survival (DFS) was longer in laparoscopic group (P=0.02). According to the results, in patients, whose primary colorectal cancer and metastatic liver disease was amenable to a minimally invasive resection, a concomitant laparoscopic approach resulted in less morbidity without compromising oncologic outcomes. This suggests that a laparoscopic approach may be considered in appropriate patients by surgeons with experience in both advanced laparoscopic liver and colorectal techniques.

Although pre-operative chemoradiation therapy for advanced lower rectal cancer is a controversial treatment modality, it is increasingly used in combination with surgery. Few studies have considered the combination of chemoradiation therapy followed by laparoscopic surgery for locally advanced lower rectal cancer; therefore, this study aimed to assess the usefulness of this therapeutic combination. We retrospectively reviewed the medical records of patients with locally advanced lower rectal cancer treated by pre-operative chemoradiation therapy and surgery from February 2002 to November 2012 at Oita University. We divided patients into an open surgery group and a laparoscopic surgery group and evaluated various parameters by univariate and multivariate analyses. In total, 33 patients were enrolled (open surgery group, n=14; laparoscopic surgery group, n=19). Univariate analysis revealed that compared with the open surgery group, operative time was significantly longer, whereas intra-operative blood loss and intra-operative blood transfusion requirements were significantly less in the laparoscopic surgery group. There were no significant differences in post-operative complication and recurrence rates between the two groups. According to multivariate analysis, operative time and intra-operative blood loss were significant predictors of outcome in the laparoscopic surgery group. This study suggests that laparoscopic surgery after chemoradiation therapy for locally advanced lower rectal cancer is a safe procedure. Further prospective investigation of the long-term oncological outcomes of laparoscopic surgery after chemoradiation therapy for locally advanced lower rectal cancer is required to confirm the advantages of laparoscopic surgery over open surgery.

This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery.

Objective: To evaluate the role of nondismembered laparoscopic pyeloplasty and percutaneous endopyelotomy for ureteropelvic junction obstruction (UPJO) with low volume renal pelvis. Material and Methods: Retrospective acquired data of 34 patients of laparoscopic nondismembered pyeloplasty was compared with 26 patients of UPJO with pelvic volume less than 50 ml undergoing antegrade endopyelotomy and analyzed for clinical parameters, operative outcomes and success of procedures. All patients were followed up clinically and with diuretic renogram at regular intervals. Results: Mean age, renal pelvic volume and preoperative glomerular filtration rate (GFR) was 25 years, 43.6 ml and 42.5 ml/min, respectively in endopyelotomy group and 21 years, 34.4 ml and 39.9 ml/min, respectively in laparoscopic pyeloplasty group. Mean operative time, postoperative analgesic requirement and mean hospital stay was 100min, 250 mg and 4 days, respectively in endopyelotomy group and 210 min, 300 mg and 4 days, respectively in laparoscopic pyeloplasty group. Only operative time was significantly different between two groups (P < 0.05). Mean follow-up was 36 and 39 months and success rates were 91.2% and 88.8% in laparoscopy and endopyelotomy group, respectively (P < 0.05). No significant complication was seen in endopyelotomy group while two patients had hematuria (one requiring blood transfusion) and three had increased drain output for more than 3 days in laparoscopy group. Conclusion: Percutaneous endopyelotomy is associated with significantly less operative time and postoperative complication rate and provides equivalent success in comparison to nondismembered laparoscopic pyeloplasty in patients with UPJO and low volume pelvis. It can be a preferred minimally invasive treatment modality for such patients. PMID:19468432

Purpose To report the first case of robotic-assisted laparoscopic management of a symptomatic caliceal diverticular calculus and review the literature on laparoscopic treatment for this condition. Case report A 33-year-old obese woman with a 2×1 cm calculus within an anterior caliceal diverticulum located in the middle pole of the left kidney was referred to our service. She had already undergone two flexible ureterorenoscopies without success. We considered that a percutaneous approach would be very challenging due to stone location, thus we elected to perform a robotic-assisted laparoscopic procedure for stone removal and diverticulum fulguration. The procedure was uneventfully performed with no intraoperative or postoperative complications. The patient was discharged from the hospital on the second postoperative day and after 1.5 years of follow-up she is asymptomatic with no recurrence. Conclusions The robotic-assisted laparoscopic approach to caliceal diverticular calculi is feasible and safe, providing one more option for treatment of stones in challenging locations.

The discovery of Helicobacter pylori (H. pylori) as the culprit in peptic ulcer disease (PUD) has revolutionized its management. Despite the presence of effective drug treatments and an increased understanding of its etiology, the percentage of patients who require emergent surgery for complicated disease remains constant at 7% of hospitalized patients. This study aims at reviewing the incidence of complicated PUD and analyze changes in surgical management. From January 2002 to September 2012, records of all patients with a clinical or radiologic diagnosis of perforated PUD were evaluated. Short-term and long-term results were assessed with regard to type of surgical intervention. The primary end point was adverse events. Other end points were length of hospital stay, complications, and deaths. Included were 400 patients with a median age of 56 years (range, 17 to 89 y). Of these, males made up 70% (n=280), were older and had more comorbidities. Majority of perforations were located in the prepyloric region (80%) and duodenal bulb (20%). Nonsteroidal anti-inflammatory drug alone was involved in 50% of cases and in combination with H. pylori in 84%. H. pylori alone occurred in 40% of cases.Laparoscopic treatment was performed in 48 patients (12%) who remained hemodynamically stable. In the remaining 88% of patients, open approach was used. Simple closure with omentoplasty was performed in 98% and in 2%; definitive anti ulcer procedure was performed. Major complications occurred in 6% with an overall 30-day mortality rate of 2%. Most postoperative morbidity occurred after open approach. One patient who had laparoscopic repair died of other causes unrelated to the gastroduodenal perforation. Among the laparoscopic group, mean hospital stay was 4 days (range, 3 to 7 d), compared with 6 days (5 to 14 d) after open approach. Although the incidence of PUD is decreasing, it appears that among our patients, the incidence of complication is rising. Laparoscopic approach

Background There are scant data in the literature regarding the role of robotic liver surgery. The aim of the present study was to develop techniques for robotic liver tumour resection and to draw a comparison with laparoscopic resection. Methods Over a 1-year period, nine patients underwent robotic resection of peripherally located malignant lesions measuring <5 cm. These patients were compared prospectively with 23 patients who underwent laparoscopic resection of similar tumours at the same institution. Statistical analyses were performed using Student's t-test, χ2-test and Kaplan–Meier survival. All data are expressed as mean ± SEM. Results The groups were similar with regards to age, gender and tumour type (P = NS). Tumour size was similar in both groups (robotic −3.2 ± 1.3 cm vs. laparoscopic −2.9 ± 1.3 cm, P = 0.6). Skin-to-skin operative time was 259 ± 28 min in the robotic vs. 234 ± 17 min in the laparoscopic group (P = 0.4). There was no difference between the two groups regarding estimated blood loss (EBL) and resection margin status. Conversion to an open operation was only necessary in one patient in the robotic group. Complications were observed in one patient in the robotic and four patients in the laparoscopic groups. The patients were followed up for a mean of 14 months and disease-free survival (DFS) was equivalent in both groups (P = 0.6). Conclusion The results of this initial study suggest that, for selected liver lesions, a robotic approach provides similar peri-operative outcomes compared with laparoscopic liver resection (LLR).

Full Text Available Of the various options for patients with end stage renal disease, kidney transplantation is the treatment of choice for a suitable patient. The kidney for transplantation is retrieved from either a cadaver or a live donor. Living donor nephrectomy has been developed as a method to address the shortfall in cadaveric kidneys available for transplantation. Laparoscopic living donor nephrectomy (LLDN, by reducing postoperative pain, shortening convalescence, and improving the cosmetic outcome of the donor nephrectomy, has shown the potential to increase the number of living kidney donations further by removing some of the disincentives inherent to donation itself. The technique of LLDN has undergone evolution at different transplant centers and many modifications have been done to improve donor safety and recipient outcome. Virtually all donors eligible for an open surgical procedure may also undergo the laparoscopic operation. Various earlier contraindications to LDN, such as right donor kidney, multiple vessels, anomalous vasculature and obesity have been overcome with increasing experience. Laparoscopic live donor nephrectomy can be done transperitoneally or retroperitoneally on either side. The approach is most commonly transperitoneal, which allows adequate working space and easy dissection. A review of literature and our experience with regards to standard approach and the modifications is presented including a cost saving model for the developing countries. An assessment has been made, of the impact of LDN on the outcome of donor and the recipient.

We report our results and short term follow up of transperitoneal laparoscopic pyeloplasty for pelvi-ureteric junction (PUJ) obstruction. We have prospectively maintained a database to document our initial experience of 54 laparoscopic pyeloplasty. All procedures were carried out by one surgeon through a transperitoneal approach. The data extends from April 2005 to September 2008 and reports operative time, blood loss, complications, hospital stay, short term follow-up on symptomatic and radiological outcome. Fifty-four procedures were performed during the study period. Mean patient age was 29 years. Mean operating time was 133 minutes (range 65-300 minutes), and mean blood loss was 45 ml (range 20-300 ml). No intra operative complication occurred. Neither blood transfusion nor conversion to open surgery was required. Postoperative mean hospital stay was 3.4 days (range 3-14 days). There were 3 anastomotic leakages; 2 in the immediate postoperative period and 1 following removal of stent. They all required percutaneous drainage and prolonged stenting. Overall 47 (87%) patients have symptomatic relief and resolution of obstruction on renogram. Four (7%) patients developed recurrence. Three (5.5%) patients had symptomatic relief but have a persistent obstructive renogram. Laparoscopic pyeloplasty is an effective alternative treatment for symptomatic pelvi-ureteric junction obstruction. The results appear comparable to open pyeloplasty with decreased postoperative morbidity.

Laparoscopic surgery for gastro-esophageal acid reflux disease.

Gastro-esophageal reflux disease is a troublesome disease for many patients, severely affecting their quality of life. Choice of treatment depends on a combination of patient characteristics and preferences, esophageal motility and damage of reflux, symptom severity and symptom correlation to acid reflux and physician preferences. Success of treatment depends on tailoring treatment modalities to the individual patient and adequate selection of treatment choice. PubMed, Embase, The Cochrane Database of Systematic Reviews, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for systematic reviews with an abstract, publication date within the last five years, in humans only, on key terms (laparosc* OR laparoscopy*) AND (fundoplication OR reflux* OR GORD OR GERD OR nissen OR toupet) NOT (achal* OR pediat*). Last search was performed on July 23nd and in total 54 articles were evaluated as relevant from this search. The laparoscopic Toupet fundoplication is the therapy of choice for normal-weight GERD patients qualifying for laparoscopic surgery. No better pharmaceutical, endoluminal or surgical alternatives are present to date. No firm conclusion can be stated on its cost-effectiveness. Results have to be awaited comparing the laparoscopic 180-degree anterior fundoplication with the Toupet fundoplication to be a possible better surgical alternative. Division of the short gastric vessels is not to be recommended, nor is the use of a bougie or a mesh in the vast majority of GERD patients undergoing surgery. The use of a robot is not recommended. Anti-reflux surgery is to be considered expert surgery, but there is no clear consensus what is to be called an 'expert surgeon'. As for setting, ambulatory settings seem promising although high-level evidence is lacking. Copyright © 2013 Elsevier Ltd. All rights reserved.

Expert opinion on laparoscopic surgery for colorectal cancer parallels evidence from a cumulative meta-analysis of randomized controlled trials.

Full Text Available This study sought to synthesize survival outcomes from trials of laparoscopic and open colorectal cancer surgery, and to determine whether expert acceptance of this technology in the literature has parallel cumulative survival evidence.A systematic review of randomized trials was conducted. The primary outcome was survival, and meta-analysis of time-to-event data was conducted. Expert opinion in the literature (published reviews, guidelines, and textbook chapters on the acceptability of laparoscopic colorectal cancer was graded using a 7-point scale. Pooled survival data were correlated in time with accumulating expert opinion scores.A total of 5,800 citations were screened. Of these, 39 publications pertaining to 23 individual trials were retained. As well, 414 reviews were included (28 guidelines, 30 textbook chapters, 20 systematic reviews, 336 narrative reviews. In total, 5,782 patients were randomized to laparoscopic (n = 3,031 and open (n = 2,751 colorectal surgery. Survival data were presented in 16 publications. Laparoscopic surgery was not inferior to open surgery in terms of overall survival (HR = 0.94, 95% CI 0.80, 1.09. Expert opinion in the literature pertaining to the oncologic acceptability of laparoscopic surgery for colon cancer correlated most closely with the publication of large RCTs in 2002-2004. Although increasingly accepted since 2006, laparoscopic surgery for rectal cancer remained controversial.Laparoscopic surgery for colon cancer is non-inferior to open surgery in terms of overall survival, and has been so since 2004. The majority expert opinion in the literature has considered these two techniques to be equivalent since 2002-2004. Laparoscopic surgery for rectal cancer has been increasingly accepted since 2006, but remains controversial. Knowledge translation efforts in this field appear to have paralleled the accumulation of clinical trial evidence.

To perform the first randomized controlled trial to compare laparoscopic and open liver resection. Laparoscopic liver resection is increasingly used for the surgical treatment of liver tumors. However, high-level evidence to conclude that laparoscopic liver resection is superior to open liver resection is lacking. Explanatory, assessor-blinded, single center, randomized superiority trial recruiting patients from Oslo University Hospital, Oslo, Norway from February 2012 to January 2016. A total of 280 patients with resectable liver metastases from colorectal cancer were randomly assigned to undergo laparoscopic (n = 133) or open (n = 147) parenchyma-sparing liver resection. The primary outcome was postoperative complications within 30 days (Accordion grade 2 or higher). Secondary outcomes included cost-effectiveness, postoperative hospital stay, blood loss, operation time, and resection margins. The postoperative complication rate was 19% in the laparoscopic-surgery group and 31% in the open-surgery group (12 percentage points difference [95% confidence interval 1.67-21.8; P = 0.021]). The postoperative hospital stay was shorter for laparoscopic surgery (53 vs 96 hours, P < 0.001), whereas there were no differences in blood loss, operation time, and resection margins. Mortality at 90 days did not differ significantly from the laparoscopic group (0 patients) to the open group (1 patient). In a 4-month perspective, the costs were equal, whereas patients in the laparoscopic-surgery group gained 0.011 quality-adjusted life years compared to patients in the open-surgery group (P = 0.001). In patients undergoing parenchyma-sparing liver resection for colorectal metastases, laparoscopic surgery was associated with significantly less postoperative complications compared to open surgery. Laparoscopic resection was cost-effective compared to open resection with a 67% probability. The rate of free resection margins was the same in both groups. Our results support the continued

A best evidence topic in surgery was written according to a structured protocol. The question addressed was whether playing video games improves surgical performance in laparoscopic procedures. Altogether 142 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The details of the papers were tabulated including relevant outcomes and study weaknesses. We conclude that medical students and experienced laparoscopic surgeons with ongoing video game experience have superior laparoscopic skills for simulated tasks in terms of time to completion, improved efficiency and fewer errors when compared to non-gaming counterparts. There is some evidence that this may be due to better psycho-motor skills in gamers, however further research would be useful to demonstrate whether there is a direct transfer of skills from laparoscopic simulators to the operating table.

Surgical site infections with elective laparoscopic cholecystectomy are less frequent and less severe, leading some to suggest that prophylactic antibiotics (PA) are no longer indicated. We compared the incidence of surgical site infections before and after an institutional practice change of withholding PA for elective laparoscopic cholecystectomy. Between May 7, 2013, and March 11, 2015, no PA were given to patients selected for elective cholecystectomy by two surgeons at a single center. The only patients excluded were those who received antibiotics before surgery for any reason. All others, including those at high risk for infection, were included. The incidence and severity of infections were compared with historical controls treated with prophylaxis by the same two surgeons from November 6, 2011, to January 13, 2013. There were 268 patients in the study group and 119 patients in the control group. Infection occurred in 3.0 per cent in the study group compared with 0.9 per cent in the controls (P = 0.29). All infections were mild except one. Based on these data, the routine use of PA for elective laparoscopic cholecystectomy is not supported.

To investigate the feasibility and safety of solo surgery with single-port laparoscopic appendectomy, which is termed herein solo-SPLA (solo-single-port laparoscopic appendectomy). This study prospectively collected and retrospectively analyzed data from patients who had undergone either non-solo-SPLA (n = 150) or solo-SPLA (n = 150). Several devices were utilized for complete, skin-to-skin solo-SPSA, including a Lone Star Retractor System and an adjustable mechanical camera holder. Operating times were not significantly different between solo- and non-solo-SPLA (45.0 ± 21.0 minutes vs. 46.7 ± 26.1 minutes, P = 0.646). Most postoperative variables were also comparable between groups, including the necessity for intravenous analgesics (0.7 ± 1.2 ampules [solo-SPLA] vs. 0.9 ± 1.5 ampules [non-solo-SPLA], P = 0.092), time interval to gas passing (1.3 ± 1.0 days vs. 1.4 ± 1.0 days, P = 0.182), and the incidence of postoperative complications (4.0% vs. 8.7%, P = 0.153). Moreover, solo-SPLA effectively lowered the operating cost by reducing surgical personnel expenses. Solo-SPLA economized staff numbers and thus lowered hospital costs without lengthening of operating time. Therefore, solo-SPLA could be considered a safe and feasible alternative to non-solo-SPLA.

Abdominoperineal excision of the rectum (APER) for cancer has been associated with higher circumferential resection margin (CRM) involvement and failure of local disease control. The aim of this study was to investigate whether the introduction of laparoscopic APER altered the incidence of CRM involvement. Consecutive patients undergoing open or laparoscopic APER for adenocarcinomas of the rectum were studied. Patient demographics, preoperative staging, neoadjuvant treatment, operative findings, length of stay and pathological details were collected from operative and radiology databases and compared. There were 16 laparoscopic and 25 open APER performed over a 3-year period. Neoadjuvant therapy was given to 43.8% (7/16) of the laparoscopic group and 56.0% (14/25) of the open group. Complete laparoscopic resection was possible in 14 (87.5%) of 16 patients. The median harvested number of nodes was 14 (4-33) in both groups. The median length of stay was 7 (3-13) and 15 (9-40) days in the laparoscopic and open groups (P CRM was clear in all cases. There was no local recurrence in either group at a median follow-up of 23 months. There were no in-hospital deaths and no significant differences in overall survival. There were no significant differences in preoperative or postoperative histopathological T stage between the two groups (P = 0.057 and P = 0.121). Laparoscopic APER for selected rectal cancers can achieve comparable oncological outcome to open surgery but is associated with a much shorter length of stay. Patient and tumour characteristics must be taken into consideration when deciding on a laparoscopic approach for low rectal cancer. © 2011 The Authors.

Specimen retrieval bags have long been used in laparoscopic gynecologic surgery for contained removal of adnexal cysts and masses. More recently, the concerns regarding spread of malignant cells during mechanical morcellation of myoma have led to an additional use of specimen retrieval bags for contained "in-bag" morcellation. This review will discuss the indications for use retrieval bags in gynecologic endoscopy, and describe the different specimen bags available to date.

Transperitoneal laparoscopic approach for retrocaval ureter

Directory of Open Access Journals (Sweden)

Nagraj H

2006-01-01

Full Text Available We had a 14 year old boy, who presented with recurrent attacks of right loin pain. Investigations revealed a retrocaval ureter. A transperitoneal three port laparoscopic approach was undertaken. The retrocaval portion of ureter was excised. A double J stent was placed laparoscopically and ureteroureterostomy was done with intracorporeal suturing. The patient was discharged after 72 hours and the stent was removed on the 15th day. Follow up showed regression of hydronephrosis. We recommend this approach compared to open surgery, as it offers several advantages compared to conventional open surgery like decreased postoperative pain, decreased hospital stay and a cosmetically more acceptable surgical scar.

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

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

A recent multicenter randomized trial in achalasia patients has shown that pneumatic dilation resulted in equivalent relief of symptoms compared to laparoscopic Heller myotomy. Additionally, the cost of each treatment should be also taken in consideration. Therefore, the aim of the present study was to perform an economic analysis of the European achalasia trial. Patients with newly diagnosed achalasia were enrolled from to 2003 to 2008 in 14 centers in five European countries and were randomly assigned to either pneumatic dilation (PD) or laparoscopic Heller (LHM). The economic analysis was performed in the three centers in three different countries where most patients were enrolled (Amsterdam [NL], Leuven, [B] and Padova [I]) and then applied to all patients included in the study. The total raw costs of the two treatments per patient include the initial costs, the costs of complications, and the costs of retreatments. Two hundred and one patients, 107 (57 males and 50 females, mean age 46 CI: 43-49 years) were randomized to LHM and 94 (59 males and 34 females, mean age 46 CI 43-50 years) to PD. The total cost of PD per patient was quite comparable in the three different centers; €3397 in Padova, €3259 in Amsterdam and €3792 in Leuven. For LHM, the total costs per patient were highest in Amsterdam: €4488 in Padova, €6720 in Amsterdam, and €5856 in Leuven. In conclusion, the strategy of treating achalasia starting with PD appears the most economic approach, independent of the health system. © 2017 John Wiley & Sons Ltd.

Minimally invasive surgery (MIS) has heralded a revolution in surgical practice, with numerous advantages over open surgery. Nevertheless, it prevents the surgeon from directly touching and manipulating tissue and therefore severely restricts the use of valuable techniques such as palpation. Accordingly a key challenge in MIS is to restore haptic feedback to the surgeon. This paper reviews the state-of-the-art in laparoscopic palpation devices (LPDs) with particular focus on device mechanisms, sensors and data analysis. It concludes by examining the challenges that must be overcome to create effective LPD systems that measure and display haptic information to the surgeon for improved intraoperative assessment.

Valenza, Franco; Chevallard, Giorgio; Fossali, Tommaso; Salice, Valentina; Pizzocri, Marta; Gattinoni, Luciano

2010-06-01

Laparoscopy is widely used in the surgical treatment of a number of diseases. Its advantages are generally believed to lie on its minimal invasiveness, better cosmetic outcome and shorter length of hospital stay based on surgical expertise and state-of-the-art equipment. Thousands of laparoscopic surgical procedures performed safely prove that mechanical ventilation during anaesthesia for laparoscopy is well tolerated by a vast majority of patients. However, the effects of pneumoperitoneum are particularly relevant to patients with underlying lung disease as well as to the increasing number of patients with higher-than-normal body mass index. Moreover, many surgical procedures are significantly longer in duration when performed with laparoscopic techniques. Taken together, these factors impose special care for the management of mechanical ventilation during laparoscopic surgery. The purpose of the review is to summarise the consequences of pneumoperitoneum on the standard monitoring of mechanical ventilation during anaesthesia and to discuss the rationale of using a protective ventilation strategy during laparoscopic surgery. The consequences of chest wall derangement occurring during pneumoperitoneum on airway pressure and central venous pressure, together with the role of end-tidal-CO2 monitoring are emphasised. Ventilatory and non-ventilatory strategies to protect the lung are discussed.

Inguinal hernia repair: totally preperitoneal laparoscopic approach versus Stoppa operation: randomized trial of 100 cases.

Champault, G G; Rizk, N; Catheline, J M; Turner, R; Boutelier, P

1997-12-01

In a prospective randomized trial comparing the totally preperitoneal (TPP) laparoscopic approach and the Stoppa procedure (open), 100 patients with inguinal hernias (Nyhus IIIA, IIIB, IV) were followed over a 3-year period. Both groups were epidemiologically comparable. In the laparoscopic group, operating time was significantly longer (p = 0.01), but hospital stay (3.2 vs. 7.3 days) and delay in return to work (17 vs. 35 days) were significantly reduced (p = 0.01). Postoperative comfort (less pain) was better (p = 0.001) after laparoscopy. In this group, morbidity was also reduced (4 vs. 20%; p = 0.02). The mean follow-up was 605 days, and 93% of the patients were reviewed at 3 years. There were three (6%) recurrences after TPP, especially at the beginning of the surgeon's learning curve, versus one for the Stoppa procedure (NS). For bilateral hernias, the authors suggest the use of a large prosthesis rather than two small ones to minimize the likelihood of recurrence. In the conditions described, the laparoscopic (TPP) approach to inguinal hernia treatment appears to have the same long-term recurrence rate as the open (Stoppa) procedure but a real advantage in the early postoperative period.

Laparoscopic donor nephrectomy has become the criterion standard for kidney retrieval from living donors. There is no information on the experience and outcomes of laparoscopic donor nephrectomy in Pakistan. The objective of the study was to identify benefits and harms of using laparoscopic compared with open nephrectomy techniques for renal allograft retrieval. In this a retrospective study, patient files from May 2014 to September 2015 were analyzed. Patients were divided into 2 groups: those with open donor nephrectomy and those with laparoscopic donor nephrectomy. Donor case files and operative notes were analyzed for age, sex, laterality, body mass index, warm ischemia time, perioperative and postoperative complications, surgery time, and length of hospital stay. Finally, serum creatinine patterns of both donors and recipients were analyzed. Data were analyzed using SPSS version 10 (SPSS: An IBM Company, IBM Corporation, Armonk, NY, USA). Of 388 total donors, 190 (49%) had open donor nephrectomy and 198 (51%) had laparoscopic donor nephrectomy. For both groups, most donors were older than 25 years with male preponderance. Left-to-right kidney donation ratio was markedly higher in the laparoscopic group than in the open donor nephrectomy group, with 6 cases of double renal artery also included in this study. There were no significant differences in surgery times between the 2 groups, whereas the laparoscopic donor nephrectomy group had shorter hospital stay. Analgesic requirements were markedly shorter in the laparoscopic donor nephrectomy group. The 1-year graft function was not significantly different between the 2 groups. The results for laparoscopic donor nephrectomy were comparable to those for open donor nephrectomy, and its acceptability was high. Laparoscopic donor nephrectomy should be the preferred approach for procuring the kidney graft.

To compare patient-satisfaction, scar-pain and cosmesis between laparoscopic and open-cholecystectomy. Cross-sectional survey. Khyber Teaching Hospital, Peshawar, from August 2012 to May 2014. A total of 400 patients, who had undergone open or laparoscopic cholecystectomy in all units of the Surgical Department, were included. Data was collected on questionnaires given and read to the patients along with counselling and information regarding scar-pain using visual analog score, and satisfaction and cosmesis on a 0 - 10 scale, by a medical professional in the patients' native language. This was done postoperatively on patients' follow-up visits at 1 and 4 weeks. Mean scar pain score at 1 and 4 weeks postoperatively was higher for open-cholecystectomy; 4.96 ±1 and 0.96 ±1, compared to 2.24 ±0.6 and 0, respectively for laparoscopic-cholecystectomy (p < 0.001 and < 0.001). Cosmesis was higher for laparoscopic-group; 8.6 ±1.2 vs. 6.2 ±1.46 for open-cholecystectomy (p < 0.001). Patient-satisfaction was higher for laparoscopic-cholecystectomy; 9.28 ±1.5 vs. 8.32 ±2.3 for open-cholecystectomy (p < 0.001). Mean-cosmesis score was higher for laparoscopic-cholecystectomy for those younger than 40, females and unmarried. Mean patient-satisfaction score was higher for those older than 40 years who had undergone open-cholecystectomy, women who had undergone laparoscopic-cholecystectomy and for unmarried patients who had laparoscopic-cholecystectomy. Overall patient-satisfaction and cosmesis scoring was higher for laparoscopic-cholecystectomy especially among females, unmarried and younger than 40 years. Patients of 40 years and older had greater satisfaction scoring for open-cholecystectomy. Therefore, laparoscopic-cholecystectomy should be favoured in females and unmarried patients and those younger than 40 years.

The management of Incarcerated Inguinal Hernia (IIH) in children is challenging and may be associated with complications. We aimed to compare the outcomes of laparoscopic vs. open repair of IIH. With institutional ethical approval (09SG13), we reviewed the notes of 63 consecutive children who were admitted to a single hospital with the diagnosis of IIH between 2000 and 2008. Data are reported as median (range). Groups were compared by chi-squared or t-tests as appropriate. · Open repair (n=35): There were 21 children with right and 14 with left IIH. 2 patients also had contralateral reducible inguinal hernia. Small bowel resection was required in 2 children. · Laparoscopic repair (n=28): All children had unilateral IIH (19 right sided, 9 left sided). 15 children (54%) with no clinical evidence of contralateral hernia, had contralateral patent processus vaginalis at laparoscopy, which was also repaired. The groups were similar with regard to gender, age at surgery, history of prematurity, interval between admission and surgery, and proportion of patients with successful preoperative manual reduction. However, the duration of operation was longer in the laparoscopy group (p=0.01). Time to full feeds and length of hospital stay were similar in both groups. Postoperative follow-up was 3.5 months (1-36), which was similar in both groups. 5 patients in the group undergoing open repair had serious complications: 1 vas transaction, 1 acquired undescended testis, 2 testicular atrophy and 1 recurrence. The laparoscopic group had a single recurrence. Open repair of incarcerated inguinal hernia is associated with serious complications. The laparoscopic technique appears safe, avoids the difficult dissection of an oedematous sac in the groin, allows inspection of the reduced hernia content and permits the repair of a contralateral patent processus vaginalis if present. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of this study is to evaluate if 3-dimensional high-definition (3D) vision in laparoscopy can prompt advantages over conventional 2D high-definition vision in hiatal hernia (HH) repair. Between September 2012 and September 2015, we randomized 36 patients affected by symptomatic HH to undergo surgery; 17 patients underwent 2D laparoscopic HH repair, whereas 19 patients underwent the same operation in 3D vision. No conversion to open surgery occurred. Overall operative time was significantly reduced in the 3D laparoscopic group compared with the 2D one (69.9 vs 90.1 minutes, P = .006). Operative time to perform laparoscopic crura closure did not differ significantly between the 2 groups. We observed a tendency to a faster crura closure in the 3D group in the subgroup of patients with mesh positioning (7.5 vs 8.9 minutes, P = .09). Nissen fundoplication was faster in the 3D group without mesh positioning ( P = .07). 3D vision in laparoscopic HH repair helps surgeon's visualization and seems to lead to operative time reduction. Advantages can result from the enhanced spatial perception of narrow spaces. Less operative time and more accurate surgery translate to benefit for patients and cost savings, compensating the high costs of the 3D technology. However, more data from larger series are needed to firmly assess the advantages of 3D over 2D vision in laparoscopic HH repair.

2007-10-01

To highlight the clinical and experimental rationales that support why the Roux-en-Y limb is an important surgical principle for bariatric gastric bypass. We reviewed PubMed citations for open Roux-en-Y gastric bypass (RYGBP), laparoscopic RYGBP, loop gastric bypass, chronic alkaline reflux gastritis, and duodenoesophageal reflux. We reviewed clinical and experimental articles. Clinical articles included prospective, retrospective, and case series of patients undergoing RYGBP, laparoscopic RYGBP, or loop gastric bypass. Experimental articles that were reviewed included in vivo and in vitro models of chronic duodenoesophageal reflux and its effect on carcinogenesis. No formal data extraction was performed. We reviewed published operative times, lengths of stay, and anastomotic leak rates for laparoscopic RYGBP and loop gastric bypass. For in vivo and in vitro experimental models of duodenoesophageal reflux, we reviewed the kinetics and potential molecular mechanisms of carcinogenesis. Recent data suggest that laparoscopic loop gastric bypass, performed without the creation of a Roux-en-Y gastroenterostomy, is a faster surgical technique that confers similarly robust weight loss compared with RYGBP or laparoscopic RYGBP. In the absence of a Roux limb, the long-term effects of chronic alkaline reflux are unknown. Animal models and in vitro analyses of chronic alkaline reflux suggest a carcinogenic effect.

Rules and technical tricks in extremely difficult laparoscopic cholecystectomies

Full Text Available We remind you of some technical artifices required in order to resolve difficult cases, such as: antegrade laparoscopic cholecystectomy (LC, subtotal laparoscopic cholecystectomy (SLC and the “stairs” clipping of the cystic duct. Also we acknowledge the closing of the cystic duct. We analyzed the medical records of 15251 laparoscopic cholecystectomies performed during 1994-2015, with emphasis on: surgical technique, conversion rate, hemorrhage, postoperative bile leaking, iatrogenic MBD injuries and mortality. We divided the cases in 5 study groups, group 1 (1994- 2004 N= 5138, group 2 (2005-2015 N= 10113, group 3 (fundus first cholecystectomies, N=2348, group 4 (retrograde cholecystectomies, N=12889 and group 5 (subtotal laparoscopic cholecystectomy-SLC, N=14 which we compared regarding the main parameters. We prefer to perform a “step by step” clipping each time the length of the clip does not cover all the circumference of the cystic duct. This artifices, is a simple laparoscopic gesture easy to perform and has the advantage of avoiding a large excessive and risky laparoscopic dissection in the vicinity of the main biliary duct. More seldom we appeal to the suture of the cystic stump using the intracorporeal knots or a simple stump ligation with an extracorporeal preformed not. We did not encounter any late or early complications following the implementation of this technical laparoscopic artifice. Laborious laparoscopic cholecystectomies performed by a well-trained surgical team ensure the premises of a good performance even while adopting laparoscopic ingenious and difficile gestures that also respect the intraoperatory rules and principals.

Laparoscopic distal pancreatectomy (LDP) reduces postoperative morbidity, hospital stay and recovery as compared with open distal pancreatectomy. Many authors believe that robotic surgery can overcome the difficulties and technical limits of LDP thanks to improved surgical manipulation and better visualization. Few studies in the literature have compared the two methods in terms of surgical and oncological outcome. The aim of this study was to compare the results of robotic (RDP) and laparoscopic distal pancreatectomy. A systematic review and meta-analysis was conducted of control studies published up to December 2016 comparing LDP and RDP. Two Reviewers independently assessed the eligibility and quality of the studies. The meta-analysis was conducted using either the fixed-effect or the random-effect model. Ten studies describing 813 patients met the inclusion criteria. This meta-analysis shows that the RDP group had a significantly higher rate of spleen preservation [OR 2.89 (95% confidence interval 1.78-4.71, p < 0.0001], a lower rate of conversion to open OR 0.33 (95% CI 0.12-0.92), p = 0.003] and a shorter hospital stay [MD -0.74; (95% CI -1.34 -0.15), p = 0.01] but a higher cost than the LDP group, while other surgical outcomes did not differ between the two groups. This meta-analysis suggests that the RDP procedure is safe and comparable in terms of surgical results to LDP. However, even if the RDP has a higher cost compared to LDP, it increases the rate of spleen preservation, reduces the risk of conversion to open surgery and is associated to shorter length of hospital stay.

Uncertainties about laparoscopic myomectomy during pregnancy: A lack of evidence or an inherited misconception? A critical literature review starting from a peculiar case.

The aim of this report was to perform a critical review of the literature about feasibility, safety, limitations and contraindications of laparoscopic myomectomy during pregnancy starting from a peculiar case of a 15-weeks pregnant woman affected by a symptomatic large myoma. A 35 year-old Caucasian-nulliparous-woman was referred to our unit at nine weeks of gestation for abdominal heaviness and constipation. The ultrasound examination revealed the presence of a 24 cm pedunculated myoma. The initial management was conservative until the achievement of 15 gestational weeks, when the worsening of abdominal pain led to the need of a laparoscopic myomectomy. Intraoperative blood-loss was 600 ml and operating-time was 150 minutes (70 minutes were required for the morcellement); the postoperative course was normal. The pregnancy evolved regularly and, at 41 weeks, the patient delivered by urgent caesarean section (because intrapartum fetal heart rate abnormalities) a healthy male baby weighing 4460 gr. Both post-partum and puerperium period had a regular course. Laparoscopic myomectomy is feasible and safe during pregnancy for both mother and fetus and vaginal delivery should not be contraindicated. Evidence from our and other reported cases suggests that, during pregnancy, laparoscopic myomectomy should be considered the best surgical choice when subserous peduncolated myomas are symptomatic.

Rivier, Pablo; Furneaux, Rob; Viguier, Eric

2011-01-01

This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

Growing evidence suggests that the level of pneumoperitoneal pressure is directly correlated with postoperative pain in patients undergoing laparoscopic procedures. However, only limited evidence is available in the field of gynaecologic surgery. Therefore, this study aimed to compare the effects of low (8mmHg), standard (12mmHg) and high (15mmHg) pneumoperitoneal pressures (LPPlaparoscopic procedures confined to the pelvis. The primary outcome was to evaluate if changes in pneumoperitoneal pressure influence postoperative pain. The study also sought to determine the safety of LPP during gynaecologic procedures. A literature search revealed two randomized controlled trials that evaluated the effects of different pneumoperitoneal pressures. Overall, 230 patients who underwent gynaecologic procedures via laparoscopy using different pneumoperitoneal pressures (LPP: n=74, 32%; SPP: n=67, 29%; HPP: n=89, 39%) were evaluated. Pooled results suggested that the use of LPP does not increase operative time compared with SPP [mean difference (MD) 6.78min] and HPP (MD 5.52min). Similarly, no differences in operative time were recorded between procedures using SPP and HPP (MD 0.34min). Estimated blood loss was not influenced by CO2 intra-abdominal pressure (LPP vs SPP: MD 10.05ml; LPP vs HPP: MD -4.03ml; SPP vs HPP: MD 6.75ml). Twenty-four hours after surgery, HPP was found to be correlated with higher levels of pain compared with LPP and SPP. However, CO2 pressure did not influence the length of hospital stay. These results suggest that in comparison with SPP and HPP, LPP provides a slight benefit in terms of postoperative pain among patients undergoing gynaecologic laparoscopy, with no increase in operative time, blood loss or surgery-related morbidity.

Laparoscopic versus open radical cystectomy in bladder cancer: a systematic review and meta-analysis of comparative studies.

Directory of Open Access Journals (Sweden)

Kun Tang

Full Text Available BACKGROUND AND OBJECTIVE: More recently laparoscopic radical cystectomy (LRC has increasingly been an attractive alternative to open radical cystectomy (ORC and many centers have reported their early experiences in the treatment of bladder cancer. Evaluate the safety and efficacy of LRC compared with ORC in the treatment of bladder cancer. METHODS: A systematic search of Medline, Scopus, and the Cochrane Library was performed up to Mar 1, 2013. Outcomes of interest assessing the two techniques included demographic and clinical baseline characteristics, perioperative, pathologic and oncological variables, and post-op neobladder function and complications. RESULTS: Sixteen eligible trials evaluating LRC vs ORC were identified including seven prospective and nine retrospective studies. Although LRC was associated with longer operative time (p<0.001, patients might benefit from significantly fewer overall complications (p<0.001, less blood loss (p<0.001, shorter length of hospital stay (p<0.001, less need of blood transfusion (p<0.001, less narcotic analgesic requirement (p<0.001, shorter time to ambulation (p = 0.03, shorter time to regular diet (p<0.001, fewer positive surgical margins (p = 0.006, fewer positive lymph node (p = 0.05, lower distant metastasis rate (p = 0.05 and fewer death (p = 0.004. There was no significant difference in other demographic parameters except for a lower ASA score (p = 0.01 in LRC while post-op neobladder function were similar between the two groups. CONCLUSIONS: Our data suggest that LRC appears to be a safe, feasible and minimally invasive alternative to ORC with reliable perioperative safety, pathologic & oncologic efficacy, comparable post-op neobladder function and fewer complications. Because of the inherent limitations of the included studies, further large sample prospective, multi-centric, long-term follow-up studies and randomized control trials should be undertaken to confirm our

BACKGROUND: Preoperative oral carbohydrate can attenuate postoperative insulin resistance and catabolism, and may have the potential to improve postoperative recovery. There are no data from randomized studies on postoperative clinical outcome after specific surgical procedures. This study...... evaluated the clinical effects of a preoperative carbohydrate beverage in patients undergoing laparoscopic cholecystectomy. METHODS: Ninety-four patients undergoing laparoscopic cholecystectomy were included in a randomized clinical trial. Patients were randomized to receive 800 ml of an iso-osmolar 12.......5 per cent carbohydrate-rich beverage the evening before operation (100 g carbohydrate) and another 400 ml (50 g carbohydrate) 2 h before initiation of anaesthesia, or the same volume of a placebo beverage. The primary endpoint was general well-being the day after operation. Patients were evaluated from...

Full Text Available Purpose: To assess the effectiveness and safety of robot-assisted radical prostatectomy (RARP versus laparoscopic radical prostatectomy (LRP in the treatment of prostate cancer. Materials and Methods: Existing systematic reviews were updated to investigate the effectiveness and safety of RARP. Electronic databases, including Ovid MEDLINE, Ovid Embase, the Cochrane Library, KoreaMed, Kmbase, and others, were searched through July 2014. The quality of the selected systematic reviews was assessed by using the revised assessment of multiple systematic reviews (R-Amstar and the Cochrane Risk of Bias tool. Meta-analysis was performed by using Revman 5.2 (Cochrane Community and Comprehensive Meta-Analysis 2.0 (CMA; Biostat. Cochrane Q and I2 statistics were used to assess heterogeneity. Results: Two systematic reviews and 16 additional studies were selected from a search performed of existing systematic reviews. These included 2 randomized controlled clinical trials and 28 nonrandomized comparative studies. The risk of complications, such as injury to organs by the Clavien-Dindo classification, was lower with RARP than with LRP (relative risk [RR], 0.44; 95% confidence interval [CI], 1.23–0.85; p=0.01. The risk of urinary incontinence was lower (RR, 0.43; 95% CI, 0.31–0.60; p<0.000001 and the potency rate was significantly higher with RARP than with LRP (RR, 1.38; 95% CI, 1.11–1.70; I2 =78%; p=0.003. Regarding positive surgical margins, no significant difference in risk between the 2 groups was observed; however, the biochemical recurrence rate was lower after RARP than after LRP (RR, 0.59; 95% CI, 0.48–0.73; I2 =21%; p<0.00001. Conclusions: RARP appears to be a safe and effective technique compared with LRP with a lower complication rate, better potency, a higher continence rate, and a decreased rate of biochemical recurrence.

Laparoscopic simulation for all: two affordable, upgradable, and easy-to-build laparoscopic trainers.

Smith, Matthew D; Norris, Joseph M; Kishikova, Lyudmila; Smith, David P

2013-01-01

Laparoscopic surgery has established itself as the approach of choice for a multitude of operations in general, urological, and gynecological surgery. A number of factors make performing laparoscopic surgery technically demanding, and as such it is crucial that surgical trainees hone their skills safely on trainers before operating on patients. These can be highly expensive. Here, we describe a novel and upgradable approach to constructing an affordable laparoscopic trainer. A pattern was produced to build an upgradable laparoscopic trainer for less than $100. The basic model was constructed from an opaque plastic crate with plywood base, 2 trocars, and 2 pairs of disposable laparoscopic instruments. A laptop, a light emitting diode (LED), and a fixed webcam were utilized to visualize the box interior. An enhanced version was also created, as an optional upgrade to the basic model, featuring a neoprene-trocar interface and a simulated mobile laparoscope. The described setup allowed trainees to gain familiarity with laparoscopic techniques, beginning with simple manipulation and then progressing through to more relevant procedures. Novices began by moving easy-to-grasp objects between containers and then attempting more challenging manipulations such as stacking sugar cubes, excising simulated lesions, threading circular mints onto cotton, and ligating fastened drinking straws. These techniques have introduced the necessity of careful instrument placement and have increased trainees' dexterity with laparoscopy. Here, we have outlined an upgradable and affordable alternative laparoscopic trainer that has given many trainees crucial experience with laparoscopic techniques, allowing them to safely improve their manual skill and confidence.

PRINCIPLES OF SAFETY IN LAPAROSCOPIC CHOLECYSTECTOMY

Directory of Open Access Journals (Sweden)

Full Text Available Background. After more than decade of routine use of laparoscopic cholecystectomy for treatment of symptomatic gallbladder stones, the incidence of biliary injuries, which are potentially life threatening and cause prolonged hospitalization and major morbidity, seems to be increased in laparoscopic cholecystectomy compared with open operation. Injury rate was from some reports 2.5 to 4 times higher than with open operation. There are many proposed classifications of types of biliary injuries.The most frequent direct causes of laparoscopic biliary injury are misidentification of the common bile duct, cautery injuries to the bile duct and improper application of clips to the cystic duct.Conclusions. To avoid misidentification of ducts one should conclusively identify cystic duct and artery, the structures to be divide, in every laparoscopic cholecystectomy. To achieve that goal, Calot’s triangle must be dissected free of fat and fibrous – tissue and the lower end of the gallbladder must be dissected of the liver bed. The only two structures entering the gallbladder should be visible – cystic duct and artery. With avoidance of blind application of cautery and clips to control bleeding one should avoid injury of bile duct. Low cautery settings should be used in portal dissections to prevent arc.With meticulous care in dissection and conclusive identification of cystic duct and artery we can prevent injuries of bile duct, which still have impermissible high incidence. In the article 504 laparoscopic cholecystectomies performed at the Department of abdominal surgery in BPD in 2002 were analysed. We follow priciples of safety in laparoscopic cholecystectomy. There were no biliary injuries reports.

A STUDY ON OPEN VS. LAPAROSCOPIC APPROACH IN ACUTE APPENDICITIS

Full Text Available Reginald Fitz in 1986, first described acute appendicitis. Since the acute appendicitis was first described, the pathology remains the most common intra-abdominal condition requiring emergency surgery. The life time risk of having acute appendicitis is about 8%. Traditionally, the treatment of choice has been surgery. Before the only option was the open laparotomical meaning opening the abdominal cavity was the mode of operation. Laparoscopic appendectomy was described by Semm in 1983. This method was new and had its own benefits but this particular procedure has struggled to prove its superiority over the open technique. This is contrast to laparoscopic cholecystectomy which has promptly become the gold standard for gallstone disease despite little scientific challenge. This peculiarity might be because of the fact that the Open Appendectomy was used for centuries with good effect. The particular procedure withstood the test of time for more than a century since its introduction by McBurney unlike cholecystectomy. Open surgery is typically completed using a small right lower quadrant incision between the point joining the lateral one-third and medial two-third of a line drawn from anterior-superior iliac spine and the umbilicus. The postoperative recovery is usually uneventful. The overall mortality of OA is around 0.3% and morbidity about 11%. Despite numerous randomised trials, several meta-analysis and systematic critical reviews, the clear cut winner is unannounced. A sincere effort has been put to understand the different pros and cons of the two methods so that the patient can be benefited. METHODS One Hundred cases were studied in the Department of Surgery, King George Hospital, Visakhapatnam, Andhra Pradesh from 01-09-2015 to 29-02-2016. Out of these, fifty cases underwent open surgery and the rest through laparoscopic surgery. The first group (Open Surgery thus consisted of 50 cases and the second group (laparoscopic consisted of fifty

The challenges in laparoscopic suturing include need to expertise to suture. Laparoscopic needle holder is a" key" instrument to accomplish this arduous task. The objective of this new invention was to develop a laparoscopic needle holder which would be adapted to avoid any wobble (with a shaft diameter same as a 5mm port), ensure accurate and dexterous suturing not just in adult patients but pediatric patients alike (with a short shaft diameter) and finally ensure seamless throw of knots with a narrow tip configuration. We did an initial evaluation to evaluate the validity of the prototype needle holder and its impact on laparoscopic suturing skills by experienced laparoscopic surgeons and novice laparoscopic Surgeons. Both the groups of surgeons performed two tasks. The first task was to grasp the needle and position it in an angle deemed ideal for suturing. The second task was to pass suture through two fixed points and make a single square knot. At the end of the tasks each participant was asked to complete a 5- point Likert's scale questionnaire (8 items; 4 items of handling and 4 items of suturing) rating each needle holder. In expert group, the mean time to complete task 1 was shorter with prototype 3/5 laparoscopic needle holder (11.8 sec Vs 20.8 sec). The mean time to complete task 2 was also shorter with prototype 3/5 laparoscopic needle holder (103.2 sec Vs 153.2 sec). In novice group, mean time to complete both the task was shorter with prototype 3/5 laparoscopic needle holder. The expert laparoscopic surgeons as well as novice laparoscopic surgeons performed laparoscopic suturing faster and with more ease while using the prototype 3/5 laparoscopic needle holder.

Staehr-Rye, Anne K; Rasmussen, L S; Rosenberg, J

2014-01-01

BACKGROUND: Pulmonary function may be impaired in connection with laparoscopic surgery, especially in the head-down body position, but the clinical importance has not been assessed in detail. The aim of this study was to assess pulmonary function after laparoscopic hysterectomy and laparoscopic...... cholecystectomy in the 20° head-up position or hysterectomy in the 30° head-down position. The primary outcome was the difference between arterial oxygenation (PaO2 ) 2 h postoperatively and the preoperative value. Two hours and 24 h after surgery, pulmonary shunt and ventilation-perfusion mismatch were assessed.......88). Shunt was significantly greater in the cholecystectomy group 24 h after surgery compared to the hysterectomy group [4%, 95% CI 0 to 9 vs. 0%, 95% CI 0 to 7, P = 0.02]. CONCLUSIONS: Minimal impairment in pulmonary gas exchange was found after laparoscopic surgery. Pulmonary shunt was larger after...

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

We present two cases of natural orifice specimen extraction (NOSE) after laparoscopic total colectomy and ileorectal anastomosis (TC-IRA), and we also review all of the previously reported cases. Our aim was to focus on patient selection for NOSE after TC-IRA. The PubMed and Google Scholar databases were scanned. Demographic features, surgical indications, and techniques were analyzed. Basic calculations were used for statistical analysis. A total of 13 cases were detected in addition to our 2 cases. All of the specimens were removed through the natural orifices successfully. No case required a diverting ileostomy. No patients were converted to open surgery or to conventional laparoscopy. Complications were reported in three patients. Transanal extractions were performed in 12 cases (10 colonic inertia, 2 polyposis), and transvaginal extractions were performed in 3 cases (2 malignancy, 1 colonic inertia). Both transanal and transvaginal specimen extractions after laparoscopic TC-IRA can be preferred. However, transanal extraction seems to be feasible in cases of TC for benign disease with a limited mesenteric-omental resection. If the indication is a malignancy requiring a mesenteric-omental resection, a transvaginal route should be preferred for a voluminous specimen.

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

To compare the cost of laparoscopically assisted vaginal hysterectomy (LAVH) with that of total abdominal hysterectomy (TAH) under casemix. Retrospective comparison of the costs, operating time and length of hospital stay. The 16 women undergoing consecutive LAVH and 16 age-matched women undergoing TAH between 1 February 1994 and 31 July 1995; all women were public patients undergoing hysterectomy for benign disease. Monash Medical Centre, a large tertiary teaching hospital in Melbourne, Australia, where casemix is used to determine funding and budget allocation. The difference between the costs of the two procedures was not statistically significant (P = 0.5), despite the cost of laparoscopic hysterectomy including that of disposables. The mean operating time for TAH was 86 minutes (95% CI, 65.5-106.5), compared with 120 minutes (95% CI, 100.8-140.5) for LAVH (P < 0.01). The mean length of stay in the TAH group was 5.75 days, compared with 3.25 days in the LAVH group (P < 0.001). In hysterectomy for benign gynaecological disease, the laparoscopic procedure costs the same as the total abdominal procedure. Audit such as this is important in patient management and in guiding hospitals in funding and bed allocation.

Standard surgical training has traditionally been one of apprenticeship, where the surgical trainee learns to perform surgery under the supervision of a trained surgeon. This is time-consuming, costly, and of variable effectiveness. Training using a virtual reality simulator is an option to supplement standard training. Virtual reality training improves the technical skills of surgical trainees such as decreased time for suturing and improved accuracy. The clinical impact of virtual reality training is not known. To assess the benefits (increased surgical proficiency and improved patient outcomes) and harms (potentially worse patient outcomes) of supplementary virtual reality training of surgical trainees with limited laparoscopic experience. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE and Science Citation Index Expanded until July 2012. We included all randomised clinical trials comparing virtual reality training versus other forms of training including box-trainer training, no training, or standard laparoscopic training in surgical trainees with little laparoscopic experience. We also planned to include trials comparing different methods of virtual reality training. We included only trials that assessed the outcomes in people undergoing laparoscopic surgery. Two authors independently identified trials and collected data. We analysed the data with both the fixed-effect and the random-effects models using Review Manager 5 analysis. For each outcome we calculated the mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals based on intention-to-treat analysis. We included eight trials covering 109 surgical trainees with limited laparoscopic experience. Of the eight trials, six compared virtual reality versus no supplementary training. One trial compared virtual reality training versus box-trainer training and versus no supplementary training, and one trial compared

2012-01-01

The T1 renal cancer in adults is made known; incidence, characteristics and management. Renal cell carcinoma has been the most common malignancy of the kidney, percentage is close to three percent of solid tumors of adults. The treatments for this tumor are analyzed: open radical nephrectomy, laparoscopic radical nephrectomy, open partial nephrectomy and laparoscopic partial nephrectomy. Laparoscopic partial nephrectomy has represented an alternative option acceptable, safely and with good oncological and surgical outcomes for patients, as it is used to conserve nephrons and simultaneously to resect the tumor of a complete form promoting in the future the patient present a good renal function. Additionally, a adequate oncological control has reduced the risk of submit postoperative renal failure. An evolution of laparoscopic partial nephrectomy is presented determining the procedure for renal tumors in state T1 in the adults [es

Spleen injury appears in 10% to 30% of abdominal trauma patients. Mortality among the patients in the last 20 years remains high (6% to 7%) and shows no tendency to decline. Nowadays nonoperative management is widely accepted management of patients with low-grade spleen injury, whereas management of patients with high-grade spleen injury (III and higher) is not so obvious. There are 3 methods exist in treatment of such patients: conservative (with or without angioembolization), spleen-preserving operations, and splenectomy. Today laparoscopic splenectomy is not a widely used operation and only few studies reported about successful use of laparoscopic splenectomy in patients with spleen injury.The aim of the study was to determine indications and contraindications for laparoscopic splenectomy in abdominal trauma patients and to analyze results of the operations. The study involved 42 patients with spleen injury grade III who were admitted in our institute in the years of 2010 to 2014. The patients were divided in 2 groups. Laparoscopic splenectomy was performed in 23 patients (group I) and "traditional" splenectomy was carried out in 19 patients (group II). There was no difference in the demographic data and trauma severity between the 2 groups. Noninvasive investigations, such as laboratory investigations, serial abdominal ultrasound examinations, x-ray in multiple views, and computed tomography had been performed before the decision about necessity of an operation was made. Patients after laparoscopic operations had better recovering conditions compared with patients with the same injury after "traditional" splenectomy. Neither surgery-related complications nor mortalities were registered in both groups. Laparoscopic splenectomy was more time-consuming operation than "traditional" splenectomy. We suggest that as experience of laparoscopic splenectomy is gained the operation time will be reduced. Laparoscopic splenectomy is a safe feasible operation in patients

2017-09-01

Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer. Newly qualified medical officers with minimal experience in laparoscopic surgery were invited to participate in the study and assigned to the following groups: gamers (n = 20) and non-gamers (n = 20). Analysis included participants' demographic data and baseline video gaming experience. Laparoscopic skills were assessed using a laparoscopic simulator trainer. There were no significant demographic differences between the two groups. Each participant performed three laparoscopic tasks and mean scores between the two groups were compared. The gamer group had statistically significant better results in maintaining the laparoscopic camera horizon ± 15° (p value = 0.009), in the complex ball manipulation accuracy rates (p value = 0.024) and completed the complex laparoscopic simulator task in a significantly shorter time period (p value = 0.001). Although prior video gaming experience correlated with better results, there were no significant differences for camera accuracy rates (p value = 0.074) and in a two-handed laparoscopic exercise task accuracy rates (p value = 0.092). The results show that previous video-gaming experience improved the baseline performance in laparoscopic simulator skills. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

The purpose of this study was to characterize the safety of laparoscopic pyloromyotomy and examine the effect of resident training on the occurrence of complications. Five hundred consecutive infants who underwent laparoscopic pyloromyotomy between January 1997 and December 2005 were reviewed and analyzed. Laparoscopic pyloromyotomy was successfully completed in 489 patients (97.8%). Four hundred seventeen patients were boys (83%). Intraoperative complication occurred in 8 (1.6%) patients (mucosal perforation, 7; serosal injury to the duodenum, 1). All were immediately recognized and uneventfully repaired. Six patients (1.2%) required revision pyloromyotomy for persistent or recurrent gastric outlet obstruction. There were 7 wound complications (1.4%) and no deaths. Pediatric surgery residents performed 81% of the operations, whereas 16% were done by general surgery residents (postgraduate years 3-4). There was a 5.4-fold increased risk of mucosal perforation or incomplete pyloromyotomy when a general surgery resident rather than a pediatric surgery resident performed the operation (95% confidence interval, 1.8-15.8; P = .003). These effects persisted even after controlling for weight, age, and attending experience. The laparoscopic pyloromyotomy has an excellent success rate with low morbidity. The occurrence of complications is increased when the operation is performed by a general surgery resident, even when directly supervised by pediatric surgical faculty.

2011-04-01

Surgical site infections have been categorized by the Centers for Medicare and Medicaid Services as "never events". The incidence of surgical site infection following laparoscopic urological surgery and its risk factors are poorly defined. We evaluated surgical site infection following urological laparoscopic surgery and identified possible factors that may influence occurrence. Patients who underwent transperitoneal laparoscopic procedures during a 4-year period by a single laparoscopic surgeon were retrospectively reviewed. Surgical site infections were identified postoperatively and defined using the Centers for Disease Control criteria. Clinical parameters, comorbidities, smoking history, preoperative urinalysis and culture results as well as operative data were analyzed. Nonparametric testing using the Mann-Whitney U test, multivariable logistic regression and Spearman's rank correlation coefficient were used for data analysis. In 556 patients undergoing urological laparoscopic procedures 14 surgical site infections (2.5%) were identified at mean postoperative day 21.5. Of the 14 surgical site infections 10 (71.4%) were located at a specimen extraction site. Operative time, procedure type and increasing body mass index were significantly associated with the occurrence of surgical site infections (p = 0.007, p = 0.019, p = 0.038, respectively), whereas history of diabetes mellitus (p = 0.071) and intraoperative transfusion (p = 0.053) were found to trend toward significance. Age, gender, positive urine culture, steroid use, procedure type and smoking history were not significantly associated with surgical site infection. Body mass index and operative time remained significant predictors of surgical site infection on multivariate logistic regression analysis. Surgical site infection is an infrequent complication following laparoscopic surgery with the majority occurring at the specimen extraction site. Infection is associated with prolonged operative time and

Laparoscopic choledochoduodenostomy: review of a 4-year experience with an uncommon problem.

2002-06-01

A laparoscopic choledochoduodenostomy (LCDD) may be performed when the common bile duct (CBD) is obstructed by primary or secondary stones or strictures. A biliary bypass procedure has two goals in view. The short-term goal is complete removal of stones and bypass of obstruction and stricture to restore biliary drainage. The long-term goal is preventing a recurrence of the problem. There is debate over the superiority of any one procedure to achieve both goals. Therefore, it may help the practicing clinician to be aware of the success (or failure), on a case-by-case basis, of these procedures. This awareness may help in the choice of technique. To date, since 1991, we have performed 16 LCDDs; however, in this report, we describe our results with LCDD over the last 4 years to emphasize the usefulness of this procedure. We find that it is a safe and effective procedure for treating patients with benign bile duct obstruction, even for those whose condition may be described as complicated or difficult. Evidence is slowly accumulating that LCDD is also successful in promoting long-term biliary drainage. We reviewed our LCDDs done over the past 4 years, documenting our preoperative, intraoperative, and postoperative experience. A successful LCDD was performed on all six patients. None of the patients had postoperative leaks. There was only one death, which was due to the patient's comorbidities and not the procedure itself. The hepatobiliary enzyme levels returned to normal in all of the surviving patients. The average postoperative length of stay was 6 days. With proper selection and adequate laparoscopic experience, LCDD can be performed in a safe and effective way.

To analyse the outcomes of laparoscopic versus open repair for perforated peptic ulcers (PPU). All patients undergoing PPU repair between January 2002 and March 2012 were included in the study. Demographic characteristics, operation time, complications, and length of hospital stay were evaluated. Two hundred and twelve patients (median age, 49 years) were included, 60 in the laparoscopic group and 52 in the open group. Patients operated laparoscopically were significantly younger and had a higher consumption of tobacco, alcohol and cannabis. Median acute symptoms time was shorter in the laparoscopic group (6h) compared to the open group (12h; P=.025) Symptoms time was shorter in the laparoscopic group. Median operating time was significantly longer in the laparoscopic group (104.5min vs. 76min, P=.025). The percentage of conversion to open repair was 25%. There was no difference in morbidity between 2 groups, but there were 3 deaths in the open group. Median hospital stay was significantly shorter in patients treated laparoscopically when compared with the open group (6 days vs. 8 days; P=.041). Laparoscopic and open repair are equally safe in the management of PPU. A shorter hospital stay can be achieved in the laparoscopic group. Copyright © 2012 AEC. Published by Elsevier Espana.

Laparoscopic colectomy for both benign and malignant disease, including inflammatory bowel disease (IBD), has recently been shown to have many advantages compared with open surgery. This study aimed to compare the effect of laparoscopic versus open subtotal colectomy (STC) for IBD on overall morbidity. A total of 99 patients undergoing STC for IBD at our institution from 2007 through 2011 were identified. Patients undergoing open STC were compared with patients undergoing laparoscopic STC. Outcomes included 30-day morbidity, conversion to laparotomy, intraoperative blood loss, operative time, admission time, late onset complications and 30-day mortality. Results are presented as median values. A total of 57 patients underwent open STC (Group 1) and 42 patients laparoscopic STC (Group 2). Group 1 comprised 26 males and 31 females, with a median age of 35 years and a body mass index (BMI) of 23.2 kg/m2. Group 2 comprised 18 males and 24 females, with a median age of 34 years and a BMI of 23.5 kg/m2. Group 2 had less morbidity (42.9% versus 75.4%, p < 0.002), reduced blood loss (100 ml versus 200 ml, p < 0.001), longer operative time (193.5 min. versus 128 min., p < 0.001), shorter length of hospital stay (six days versus 16 days, p < 0.001) than Group 1. One patient died (Group 1). There was no difference in late onset complications and no conversions to laparotomy in the laparoscopic group. Laparoscopic STC has a longer operative time, but improves short-term outcomes compared with open surgery. not relevant. not relevant.

Laparoscopic resection for transverse colon cancer remains controversial. The aim of this study is to investigate the short- and long-term outcomes of laparoscopic surgery for transverse colon cancer. A total of 278 patients with transverse colon cancer from a single institution were included. All patients underwent curative surgery, 156 patients underwent laparoscopic resection (LR), and 122 patients underwent open resection (OR). The short- and long-term results were compared between two groups. Baseline demographic and clinical characteristics were comparable between two groups. Conversions were required in eight (5.1 %) patients. LR group was associated with significantly longer median operating time (180 vs. 140 min; P colon cancer is associated with better short-term outcomes and equivalent long-term oncologic outcomes.

Schwannomas are usually benign tumors attached to peripheral nerves and are rarely found in the gastrointestinal tract. Schwannomas in the porta hepatis are extremely rare, with only 15 cases described in the literature to date. A 22-year-old female patient presented with colicky upper abdominal pain lasting 3 months. Magnetic resonance imaging of the abdominal cavity revealed a tumor in the porta hepatis. The patient was qualified for laparoscopy. The tumor was totally excised laparoscopically under guidance of laparoscopic ultrasound without intra- or postoperative complications. Postoperative histopathological examination confirmed the porta hepatic schwannoma. The patient recovered uneventfully with very good cosmetic results. In the follow-up period of 5 months we have not observed any abdominal or general health problems. The present case is the first report in the world of laparoscopic ultrasound guided laparoscopic excision of a porta hepatic schwannoma.

Laparoscopic adhesiolysis has been demonstrated to be technically feasible in small bowel obstruction and carries advantages in terms of post-surgical course. The increasing dissemination of laparoscopic surgery in the emergency setting and the lack of concrete evidence in the literature have called for a consensus conference to draw recommendations for clinical practice. A literature search was used to outline the evidence, and a consensus conference was held between experts in the field. A survey of international experts added expertise to the debate. A public jury of surgeons discussed and validated the statements, and the entire process was reviewed by three external experts. Recommendations concern the diagnostic evaluation, the timing of the operation, the selection of patients, the induction of the pneumoperitoneum, the removal of the cause of obstructions, the criteria for conversion, the use of adhesion-preventing agents, the need for high-technology dissection instruments and behaviour in the case of misdiagnosed hernia or the need for bowel resection. Evidence of this kind of surgery is scanty because of the absence of randomized controlled trials. Nevertheless laparoscopic skills in emergency are widespread. The recommendations given with the consensus process might be a useful tool in the hands of surgeons. © 2012 The Authors.

Full Text Available Since its introduction at the end of the 20th century, laparoscopic cholecystectomy has evolved into a safe and convenient minimally invasive surgical method, which is now the gold standard therapy for cholelithiasis worldwide. Physicians have continued to improve upon the procedure, creating methods that further minimize the related scarring and pain, such as the laproendoscopic single-site cholecystectomy and the gasless-lift laparoscopy. Additionally, the primary challenge of limited operative space in these procedures remains a key feature requiring improvement. In this review, the development and progression of laparoscopic cholecystectomy over the past 26 years is discussed, highlighting the current advantages and disadvantages that need to be addressed by practicing physicians to maximize the clinical value of this important therapy.

Laparoscopic repair of ventral and incisional hernia has become increasingly popular as compared to open repair. The procedure has the advantages of minimal access surgery, reduction of post operative pain and the recurrence rate. A prospective study of laparoscopic incisional hernia repair was performed in our center from August 2002 to April 2004. Eighteen cases (n: 18) were performed during the study period. Fifteen cases (n: 15) had open hernia repair previously. Sixteen patients (n: 16) had successful repair of the hernia with the laparoscopic approach and two cases were converted to open repair. The mean hernia defect size was 156cm2. There was no intraoperative or immediate postoperative complication. The mean operating time was 100 +/- 34 minutes (75 - 180 minutes). The postoperative pain was graded as mild to moderate according to visual analogue score. The mean day of discharge after surgery was two days (1 - 3 days). During follow up, three patients (16.7%) developed seroma at the hernia sac which was resolved with conservative management after three weeks. One (5.6%) patient developed recurrence six months after surgery. In conclusion, laparoscopic repair of incisional hernia particularly recurrent hernia has been shown to be safe and effective in our centre. However, careful patient selection and acquiring the necessary advanced laparoscopic surgical skills coupled with the proper use of equipment are mandatory before embarking on this procedure.

The Evolution of the Appendectomy: From Open to Laparoscopic to Single Incision

Full Text Available Beginning with its initial description by Fitz in the 19th century, acute appendicitis has been a significant long-standing medical challenge; today it remains the most common gastrointestinal emergency in adults. Already in 1894, McBurney advocated for the surgical removal of the inflamed appendix and is credited with the initial description of an Open Appendectomy (OA. With the introduction of minimally invasive surgery, this classic approach evolved into a procedure with multiple, smaller incisions; a technique termed Laparoscopic Appendectomy (LA. There is much literature describing the advantages of this newer approach. To name a few, patients have significantly less wound infections, reduced pain, and a reduction in ileus compared with the OA. In the past few years, Single Incision Laparoscopic Appendectomy (SILA has gained popularity as the next major evolutionary advancement in the removal of the appendix. Described as a pioneer in the era of “scarless surgery,” it involves only one transumbilical incision. Patients are postulated to have reduced post-operative complications such as infection, hernias, and hematomas, as well as a quicker recovery time and less post-operative pain scores, in comparison to its predecessors. In this review, we explore the advancement of the appendectomy from open to laparoscopic to single incision.

Carbon Dioxide Embolism during Laparoscopic Surgery

Park, Eun Young; Kwon, Ja-Young

2012-01-01

Clinically significant carbon dioxide embolism is a rare but potentially fatal complication of anesthesia administered during laparoscopic surgery. Its most common cause is inadvertent injection of carbon dioxide into a large vein, artery or solid organ. This error usually occurs during or shortly after insufflation of carbon dioxide into the body cavity, but may result from direct intravascular insufflation of carbon dioxide during surgery. Clinical presentation of carbon dioxide embolism ranges from asymptomatic to neurologic injury, cardiovascular collapse or even death, which is dependent on the rate and volume of carbon dioxide entrapment and the patient's condition. We reviewed extensive literature regarding carbon dioxide embolism in detail and set out to describe the complication from background to treatment. We hope that the present work will improve our understanding of carbon dioxide embolism during laparoscopic surgery. PMID:22476987

By means of a matched-pair analysis comparing data obtained from laparoscopic cholecystectomy (LC) and robot-assisted laparoscopic cholecystectomy (RAC), the value of both methods as well as the advantages and disadvantages of both approaches were elucidated. The consideration was carried out by evaluation of postoperative surgical results, a cost analysis and a subjective survey of the patients using a questionnaire. Thus, from the 35 consecutive RAC, 35 (parallel) retrospectively matched pairs were established. Postoperative surgical results did not show any significant differences between LC and RAC. In the individual assessment by each patient, there were also no significant differences; however, there was a tendency towards the assessment of the RAC to be slightly worse. A striking difference was found with respect to the cost analysis at the time of surgery. The RAC operation alone is significantly more expensive compared to LC with respect to maintenance and acquisition costs. In addition, RAC can at present not be completely reimbursed under the current German diagnosis-related system. The postulated advantages of RAC comprise mainly the precise preparation within narrow confinements and the favorable ergonomic handling for the surgeon. The basic prerequisites are control of the costs and a reasonable reflection in the current reimbursement system.

Laparoscopic colectomy procedures and their corresponding difficulty levels may vary depending on the tumor location within the colon, and a laparoscopic complete mesocolic excision (CME) with central vascular ligation (CVL) would require more proficiency than a conventional laparoscopic colectomy. We aimed to report our laparoscopic CME with CVL data and to investigate the clinical outcome differences of laparoscopic CME with CVL by various tumor sub-site locations. Prospectively collected clinical data of consecutive patients who received laparoscopic colectomy for primary colon cancer between April 1995 and December 2010 from single surgeon were retrospectively reviewed. All of the included surgery was performed on the basis of CME with CVL principle with no-touch isolation technique. Data were analyzed and compared among three groups; patients who received right or extended right hemicolectomy (group A, n = 142), transverse colectomy or left or extended left hemicolectomy (group B, n = 59), and sigmoidectomy or anterior resection (group C, n = 210). Female patients were more common in group A (53.5% vs. 37.3% vs. 39.5%, p = 0.020). Other baseline characteristics were comparable. Operative time was shorter in group C than the other groups (309.0 ± 74.7 vs. 324.3 ± 89.1 vs. 280.1 ± 93.1 min, p = 0.000). There was no significant difference among groups in perioperative complication and patient recovery. Five-year overall survival, disease-free survival and local recurrence rate showed no difference for a median follow up period of 73 (1-120) months. In conclusion, laparoscopic tumor-specific CME and CVL for colon cancer can be performed with comparable short- and long-term outcomes regardless of tumor sub-site location except for the operative time.

initiating adjuvant chemotherapy and/or radiation therapy. If the patient develops a wound infection, the infection should be more readily manageable with smaller incisions. Although not proven clinically relevant in humans, the reduction in perioperative stress associated with laparoscopic resection may translate to a cancer benefit for some patients. One report compared markers of systemic inflammatory response in 15 subjects undergoing left pancreatectomy. Eight had hand-access laparoscopic procedures and the rest had standard open surgery. The subjects in the laparoscopic group had statistically lower C-reactive protein levels than the open group on postoperative days one (5.5 mg/dL versus 9.7 mg/dL, P = .006) and three (8.5 mg/dL versus 17.7 mg/dL, P = .003), suggesting that the laparoscopic approach to left pancreatectomy is associated with less inflammation. While this report is underpowered, it supports the notion that MIS cancer surgery may induce less of a systemic insult to the body than standard open cancer surgery. More work in this area is necessary before any firm conclusions can be drawn. An important issue to consider is that of training surgeons to perform these complex procedures laparoscopically. Not all pancreatectomies are amenable to the laparoscopic approach, even in the most skilled hands. As such, only a percentage of cases will be performed this way and expectations to educate surgeons adequately to perform advanced laparoscopic procedures can be unrealistic, resulting in more "on-the-job" training. Another aspect that draws some controversy is that of the totally laparoscopic procedure versus the hand-access approach. No laparoscopic instrument provides the tactile feedback possible to obtain with the hand. The HALS approach allows for this, and the opportunity to control bleeding during the procedure. HALS also provides a way to improve confidence during the learning-curve phase of these operations. Finally, it is important to remember that if

Toward a Model of Human Information Processing for Decision-Making and Skill Acquisition in Laparoscopic Colorectal Surgery.

White, Eoin J; McMahon, Muireann; Walsh, Michael T; Coffey, J Calvin; O Sullivan, Leonard

To create a human information-processing model for laparoscopic surgery based on already established literature and primary research to enhance laparoscopic surgical education in this context. We reviewed the literature for information-processing models most relevant to laparoscopic surgery. Our review highlighted the necessity for a model that accounts for dynamic environments, perception, allocation of attention resources between the actions of both hands of an operator, and skill acquisition and retention. The results of the literature review were augmented through intraoperative observations of 7 colorectal surgical procedures, supported by laparoscopic video analysis of 12 colorectal procedures. The Wickens human information-processing model was selected as the most relevant theoretical model to which we make adaptions for this specific application. We expanded the perception subsystem of the model to involve all aspects of perception during laparoscopic surgery. We extended the decision-making system to include dynamic decision-making to account for case/patient-specific and surgeon-specific deviations. The response subsystem now includes dual-task performance and nontechnical skills, such as intraoperative communication. The memory subsystem is expanded to include skill acquisition and retention. Surgical decision-making during laparoscopic surgery is the result of a highly complex series of processes influenced not only by the operator's knowledge, but also patient anatomy and interaction with the surgical team. Newer developments in simulation-based education must focus on the theoretically supported elements and events that underpin skill acquisition and affect the cognitive abilities of novice surgeons. The proposed human information-processing model builds on established literature regarding information processing, accounting for a dynamic environment of laparoscopic surgery. This revised model may be used as a foundation for a model describing robotic

Nowadays, laparoscopic operations are a common part of surgical practice. However, they have their own characteristics and require a specific method of preparation. Recently, simulation techniques have been increasingly used for the training of skills. The aim of this review is to provide a summary of available literature on the topic of laparoscopic simulators, to assess their contribution to the training of surgeons, and to identify the most effective type of simulation. PubMed database, Web of Science and Cochrane Library were used to search for relevant publications. The keywords "laparoscopy, simulator, surgery, assessment" were used in the search. The search was limited to prospective studies published in the last 5 years in the English language. From a total of 354 studies found, we included in the survey 26 that matched our criteria. Nine studies compared individual simulators to one another. Five studies evaluated "high and low fidelity" (a virtual box simulator) as equally effective (EBM 2a). In three cases the "low fidelity" box simulator was found to be more efficient (EBM 2a3b). Only one study preferred the virtual simulator (VR) (EBM2b).Thirteen studies evaluated the benefits of simulators for practice. Twelve found training on a simulator to be an effective method of preparation (EBM 1b3b). In contrast, one study did not find any difference between the training simulator and traditional preparation (EBM 3b). Nine studies evaluated directly one of the methods of evaluating laparoscopic skills. Three studies evaluated VR simulator as a useful assessment tool. Other studies evaluated as successful the scoring system GOALS-GH. The hand motion analysis model was successful in one case. Most studies were observational (EBM 3b) and only 2 studies were of higher quality (EBM 2b). Simulators are an effective tool for practicing laparoscopic techniques (EBM: 1b). It cannot be determined based on available data which of the simulators is most effective. The

Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated diverticulitis with less morbidity than resection procedures. To compare the outcomes from laparoscopic lavage with those for colon resection for perforated diverticulitis. Multicenter, randomized clinical superiority trial recruiting participants from 21 centers in Sweden and Norway from February 2010 to June 2014. The last patient follow-up was in December 2014 and final review and verification of the medical records was assessed in March 2015. Patients with suspected perforated diverticulitis, a clinical indication for emergency surgery, and free air on an abdominal computed tomography scan were eligible. Of 509 patients screened, 415 were eligible and 199 were enrolled. Patients were assigned to undergo laparoscopic peritoneal lavage (n = 101) or colon resection (n = 98) based on a computer-generated, center-stratified block randomization. All patients with fecal peritonitis (15 patients in the laparoscopic peritoneal lavage group vs 13 in the colon resection group) underwent colon resection. Patients with a pathology requiring treatment beyond that necessary for perforated diverticulitis (12 in the laparoscopic lavage group vs 13 in the colon resection group) were also excluded from the protocol operations and treated as required for the pathology encountered. The primary outcome was severe postoperative complications (Clavien-Dindo score >IIIa) within 90 days. Secondary outcomes included other postoperative complications, reoperations, length of operating time, length of postoperative hospital stay, and quality of life. The primary outcome was observed in 31 of 101 patients (30.7%) in the laparoscopic lavage group and 25 of 96 patients (26.0%) in the colon resection group (difference, 4.7% [95% CI, -7.9% to 17.0%]; P = .53).

Laparoscopic cholecystectomies are associated with an appreciably high rate of postoperative nausea and vomiting (PONV). This study was designed to compare the effectiveness of ondansetron, granisetron, and dexamethasone for the prevention of PONV in patients after laparoscopic cholecystectomy. A total of 80 American Society of Anesthesiologists (ASA) physical class I-II patients scheduled for laparoscopic cholecystectomy were included in this randomized, double blind, placebo-controlled study. All patients received a similar standardized anesthesia and operative treatment. Patients were randomly divided into four groups (n = 20 each). Group 1, consisting of control patients, received 0.9% NaCl; group 2 patients received ondansetron 4 mg i.v.; group 3 patients received granisetron 3 mg i.v.; and group 4 patients received dexamethasone 8 mg i.v., all before the induction of anesthesia. Both nausea and vomiting were assessed during the first 24 h after the procedure. The total incidence of PONV was 75% with placebo, 35% with ondansetron, 30% with granisetron, and 25% with dexamethasone. The incidence of PONV was significantly less frequent in groups receiving antiemetics (p granisetron, and ondansetron were not significant. Prophylactic dexamethasone 8 mg i.v. significantly reduced the incidence of PONV in patients undergoing laparoscopic cholecystectomy. Dexamethasone 8 mg was as effective as ondansetron 4 mg and granisetron 3 mg, and it was more effective than placebo.

Although simulation training beneficially contributes to traditional surgical training, there are less objective data on simulation skills retention. To investigate the retention of laparoscopic and robotic skills after simulation training. We present the second stage of a randomized single-blinded controlled trial in which 40 simulation-naïve medical students were randomly assigned to practice peg transfer tasks on either laparoscopic (N = 20, Fundamentals of Laparoscopic Surgery, Venture Technologies Inc., Waltham, MA) or robotic (N = 20, dV-Trainer, Mimic, Seattle, WA) platforms. In the first stage, two expert surgeons evaluated participants on both tasks before (Stage 1: Baseline) and immediately after training (Stage 1: Post-training) using a modified validated global rating scale of laparoscopic and robotic operative performance. In Stage 2, participants were evaluated on both tasks 11-20 weeks after training. Of the 40 students who participated in Stage 1, 23 (11 laparoscopic and 12 robotic) underwent repeat evaluation. During Stage 2, there were no significant differences between groups in objective or subjective measures for the laparoscopic task. Laparoscopic-trained participants' performances on the laparoscopic task were improved during Stage 2 compared to baseline measured by time to task completion, but not by the modified global rating scale. During the robotic task, the robotic-trained group demonstrated superior economy of motion (p = .017), Tissue Handling (p = .020), and fewer errors (p = .018) compared to the laparoscopic-trained group. Robotic skills acquisition from baseline with no significant deterioration as measured by modified global rating scale scores was observed among robotic-trained participants during Stage 2. Robotic skills acquired through simulation appear to be better maintained than laparoscopic simulation skills. This study is registered on ClinicalTrials.gov (NCT02370407).

The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. Prospective descriptive study. In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.

This is the first study to explore the effects of crosstalk from 3D laparoscopic displays on technical performance and workload. We studied crosstalk at magnitudes that may have been tolerated during laparoscopic surgery. Participants were 36 voluntary doctors. To minimize floor effects, participants completed their surgery rotations, and a laparoscopic suturing course for surgical trainees. We used a counterbalanced, within-subjects design in which participants were randomly assigned to complete laparoscopic tasks in one of six unique testing sequences. In a simulation laboratory, participants were randomly assigned to complete laparoscopic 'navigation in space' and suturing tasks in three viewing conditions: 2D, 3D without ghosting and 3D with ghosting. Participants calibrated their exposure to crosstalk as the maximum level of ghosting that they could tolerate without discomfort. The Randot® Stereotest was used to verify stereoacuity. The study performance metric was time to completion. The NASA TLX was used to measure workload. Normal threshold stereoacuity (40-20 second of arc) was verified in all participants. Comparing optimal 3D with 2D viewing conditions, mean performance times were 2.8 and 1.6 times faster in laparoscopic navigation in space and suturing tasks respectively (p< .001). Comparing optimal 3D with suboptimal 3D viewing conditions, mean performance times were 2.9 times faster in both tasks (p< .001). Mean workload in 2D was 1.5 and 1.3 times greater than in optimal 3D viewing, for navigation in space and suturing tasks respectively (p< .001). Mean workload associated with suboptimal 3D was 1.3 times greater than optimal 3D in both laparoscopic tasks (p< .001). There was no significant relationship between the magnitude of ghosting score, laparoscopic performance and workload. Our findings highlight the advantages of 3D displays when used optimally, and their shortcomings when used sub-optimally, on both laparoscopic performance and workload.

Purpose: Radical trachelectomy is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. The purpose of this study was to retrospectively evaluate, in a series of 3 patients, the feasibility, morbidity, and safety of laparoscopically assisted vaginal radical trachelectomy for early cervical cancer. Patients and Methods: Three non consecutive patients with FIGO stage IA1 and IB1 cervical cancer was evaluated in a period of years 2008 - 2011. The patients underwent a laparoscopic pelvic lymphadenectomy and radical parametrectomy class II procedure according to the Piver classification. The section of vaginal cuff, trachelectomy, permanent cerclage and isthmo-vaginal anastomosis ware realised by vaginal approach. Results: The median operative time, the median blood loss and the mean number of resected pelvic nodes was comparable with published data. Major intraoperative complications did not occur and no patient required a blood transfusion. The median follow-up time was 33 (38-59) months. One vaginal recurrence occurred in 7 months after primary surgery. The patient was underwent a radicalisation procedure and adjuvant oncologic therapy and now is free of disease. Conclusions: Laparoscopically assisted vaginal radical trachelectomy (LAVRT)may be an alternative in fertility-preserving surgery for early cervical cancer. The procedure offers patients potential benefits of minimally invasive surgery with adequate oncological safety, but it should be reserved for oncologic surgeons trained in advanced laparoscopic procedures.

Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

Fibromyalgia is a chronic debilitating disorder affecting 3-5% of the US population. Treatment of this disorder is a challenge. The incidental finding of improvement of fibromyalgia following laparoscopic Roux-en-Y gastric bypass stimulated us to study this phenomenon. A retrospective chart review of patients with fibromyalgia who underwent laparoscopic Roux-en-Y gastric bypass. Postoperative decrease in median of BMI from 49.4 to 29.7 was significant (p value = 0.0010). This was associated with statistically significant improvement in median of pain score (p value = 0.0010) and median points of tenderness (p value = 0.0010). Significant weight loss following laparoscopic Roux-en-Y gastric bypass is associated with resolution or improvement of fibromyalgia. Consequently, the bariatric surgeon should be a member of the multidisciplinary team approach for treating fibromyalgia.

2009-04-01

A retrospective review of medical records was performed to assess the incidence and types of significant complications encountered during laparoscopic hysterectomy which would affect the use of a laparoscopic approach versus other routes of hysterectomy. A total of 526 consecutive patients' medical data between January 1994 and August 2007 were reviewed. Two hundred and thirty-two laparoscopic-assisted vaginal hysterectomies and 294 total laparoscopic hysterectomies were performed at Monash Medical Centre, a Melbourne tertiary public hospital, and three Melbourne private hospitals, by or under the supervision of three surgeons. Sixteen significant complications occurred. There were two cases of ureteric fistula, two bladder injuries, two bowel obstructions, four postoperative haematomas, one case of a bladder fistula, four conversions to laparotomy and one superficial epigastric artery injury. Inpatient stay ranged from two to six days. Our complication and inpatient stay rates are consistent with the previously reported rates, although there has been a reduction of incidence of visceral injuries with experience and introduction of new equipment.

Full Text Available Purpose. Short hospital stay and equal or reduced complication rates have been demonstrated after fast track open colonic surgery. However, fast track principles of perioperative care can be difficult to implement and often require increased nursing staff because of more concentrated nursing tasks during the shorter hospital stay. Specific data on nursing requirements after laparoscopic surgery are lacking. The purpose of the study was to evaluate the effect of operative technique (open versus laparoscopic operation, but without changing nurse staffing or principles for peri- or postoperative care, that is, without implementing fast track principles, on length of stay after colorectal resection for cancer. Methods. Records of all patients operated for colorectal cancer from November 2004 to December 2008 in our department were reviewed. No specific patients were selected for laparoscopic repair, which was solely dependent on the presence of two specific surgeons at the same time. Thus, the patients were not selected for laparoscopic repair based on patient-related factors, but only on the simultaneous presence of two specific surgeons on the day of the operation. Results. Of a total of 540 included patients, 213 (39% were operated by a laparoscopic approach. The median hospital stay for patients with a primary anastomosis was significantly shorter after laparoscopic than after conventional open surgery (5 versus 8 days, while there was no difference in patients receiving a stoma (10 versus 10 days, ns, with no changes in the perioperative care regimens. Furthermore there were significant lower blood loss (50 versus 200 mL, and lower complication rate (21% versus 32%, in the laparoscopic group. Conclusion. Implementing laparoscopic colorectal surgery in our department resulted in shorter hospital stay without using fast track principles for peri- and postoperative care in patients not receiving a stoma during the operation. Consequently, we

Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

2006-12-01

Full Text Available OBJECTIVE: To report our experience with laparoscopic-assisted nephroureterectomy for upper tract transitional cell carcinomas after radical cystectomy and urinary diversion. MATERIALS AND METHODS: Seven patients (53-72 years-old underwent laparoscopic-assisted nephroureterectomy 10 to 53 months after radical cystectomy for transitional cell carcinoma at our institution. Surgical technique, operative results, tumor features, and outcomes of all patients were retrospectively reviewed. RESULTS: Mean operative time was 305 minutes with a significant amount of time spent on the excision of the ureter from the urinary diversion. Estimate blood loss and length of hospital stay averaged 180 mL and 10.8 days, respectively. Intraoperative and postoperative complications occurred in two patients each. There was one conversion to open surgery. Pathology confirmed upper-tract transitional cell carcinoma in all cases. Metastatic disease occurred in two patients after a mean follow-up of 14.6 months. CONCLUSIONS: Nephrouretectomy following cystectomy is a complex procedure due to the altered anatomy and the presence of many adhesions. A laparoscopic-assisted approach can be performed safely in properly selected cases but does not yield the usual benefits seen with other laparoscopic renal procedures.

Surgery is accompanied by a surgical stress response, which results in increased morbidity and mortality. Oxidative stress is a part of the surgical stress response. Minimally invasive laparoscopic surgery may result in reduced oxidative stress compared with open surgery. Nineteen patients...... scheduled for sigmoid resection were randomly allocated to open or laparoscopic sigmoid resection in a double-blind, prospective clinical trial. Three biochemical markers of oxidative stress (malondialdehyde, ascorbic acid, and dehydroascorbic acid) were measured at 6 different time points (preoperatively......, 1 h, 6 h, 24 h, 48 h, and 72 h postoperatively). There were no statistical significant differences between laparoscopic and open surgery for any of the 3 oxidative stress parameters. Malondialdehyde was reduced 1 hour postoperatively (P...

Laparoscopic pancreatectomy: Indications and outcomes

Science.gov (United States)

Liang, Shuyin; Hameed, Usmaan; Jayaraman, Shiva

2014-01-01

The application of minimally invasive approaches to pancreatic resection for benign and malignant diseases has been growing in the last two decades. Studies have demonstrated that laparoscopic distal pancreatectomy (LDP) is feasible and safe, and many of them show that compared to open distal pancreatectomy, LDP has decreased blood loss and length of hospital stay, and equivalent post-operative complication rates and short-term oncologic outcomes. LDP is becoming the procedure of choice for benign or small low-grade malignant lesions in the distal pancreas. Minimally invasive pancreaticoduodenectomy (MIPD) has not yet been widely adopted. There is no clear evidence in favor of MIPD over open pancreaticoduodenectomy in operative time, blood loss, length of stay or rate of complications. Robotic surgery has recently been applied to pancreatectomy, and many of the advantages of laparoscopy over open surgery have been observed in robotic surgery. Laparoscopic enucleation is considered safe for patients with small, benign or low-grade malignant lesions of the pancreas that is amenable to parenchyma-preserving procedure. As surgeons’ experience with advanced laparoscopic and robotic skills has been growing around the world, new innovations and breakthrough in minimally invasive pancreatic procedures will evolve.

Full Text Available Laparoscopic surgery provides patients with less painful surgery but is more demanding for the surgeon. The increased technological complexity and sometimes poorly adapted equipment have led to increased complaints of surgeon fatigue and discomfort during laparoscopic surgery. Ergonomic integration and suitable laparoscopic operating room environment are essential to improve efficiency, safety, and comfort for the operating team. Understanding ergonomics can not only make life of surgeon comfortable in the operating room but also reduce physical strains on surgeon.

To evaluate the effect of three-dimensional (3D) visualization on operative performance during elective laparoscopic liver resection (LLR). Major limitations of conventional laparoscopy are lack of depth perception and tactile feedback. Introduction of robotic technology, which employs 3D imaging, has removed only one of these technical obstacles. Despite the significant advantages claimed, 3D systems have not been widely accepted. In this single institutional study, 20 patients undergoing LLR by high-definition 3D laparoscope between April 2014 and August 2014 were matched to a retrospective control group of patients who underwent LLR by two-dimensional (2D) laparoscope. The number of patients who underwent major liver resection was 5 (25%) in the 3D group and 10 (25%) in the 2D group. There was no significant difference in contralateral wedge resection or combined resections between the 3D and 2D groups. There was no difference in the proportion of patients undergoing previous abdominal surgery (70 vs. 77%, p = 0.523) or previous hepatectomy (20 vs. 27.5%, p = 0.75). The operative time was significantly shorter in the 3D group when compared to 2D (225 ± 109 vs. 284 ± 71 min, p = 0.03). There was no significant difference in blood loss in the 3D group when compared to 2D group (204 ± 226 in 3D vs. 252 ± 349 ml in 2D group, p = 0.291). The major complication rates were similar, 5% (1/20) and 7.5% (3/40), respectively, (p ≥ 0.99). 3D visualization may reduce the operating time compared to high-definition 2D. Further large studies, preferably prospective randomized control trials are required to confirm this.

Laparoscopic sleeve gastrectomy has become a stand-alone procedure in the treatment of morbid obesity. There are very few reports on the use of robotic approach in sleeve gastrectomy. The purpose of this retrospective study is to report our early experience of robotic-assisted laparoscopic sleeve gastrectomy (RALSG) using a proctored training model with comparison to an institutional cohort of patients who underwent laparoscopic hand-assisted sleeve gastrectomy (LASG). University hospital. The study included 108 patients who underwent sleeve gastrectomy either via the laparoscopic-assisted or robot-assisted approach during the study period. Of these 108 patients, 62 underwent LASG and 46 underwent RALSG. The console surgeon in the RALSG is a clinical year 4 (CY4) surgery resident. All CY4 surgery residents received targeted simulation training before their rotation. The console surgeon is proctored by the primary surgeon with assistance as needed by the second surgeon. The patients in the robotic and laparoscopic cohorts did not have a statistical difference in their demographic characteristics, preoperative co-morbidities, or complications. The mean operating time did not differ significantly between the 2 cohorts (121 min versus 110 min, P = .07). Patient follow-up in the LSG and RALSG were 91% and 90% at 3 months, 62% and 64% at 6 months, and 60% and 55% at 1 year, respectively. The mean percentage estimated weight loss (EWL%) at 3 months, 6 months, and 1 year was greater in the robotic group but not statistically significant (27 versus 22 at 3 mo [P = .05] and 39 versus 34 at 6 mo [P = .025], 57 versus 48 at 1 yr [P = .09]). There was no mortality in either group. Early results of our experience with RALSG indicate low perioperative complication rates and comparable weight loss with LASG. The concept of a stepwise education model needs further validation with larger studies. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc

Human perceptual capabilities related to the laparoscopic interaction paradigm are not well known. Its study is important for the design of virtual reality simulators, and for the specification of augmented reality applications that overcome current limitations and provide a supersensing to the surgeon. As part of this work, this article addresses the study of laparoscopic pulling forces. Two definitions are proposed to focalize the problem: the perceptual fidelity boundary, limit of human perceptual capabilities, and the Utile fidelity boundary, that encapsulates the perceived aspects actually used by surgeons to guide an operation. The study is then aimed to define the perceptual fidelity boundary of laparoscopic pulling forces. This is approached with an experimental design in which surgeons assess the resistance against pulling of four different tissues, which are characterized with both in vivo interaction forces and ex vivo tissue biomechanical properties. A logarithmic law of tissue consistency perception is found comparing subjective valorizations with objective parameters. A model of this perception is developed identifying what the main parameters are: the grade of fixation of the organ, the tissue stiffness, the amount of tissue bitten, and the organ mass being pulled. These results are a clear requirement analysis for the force feedback algorithm of a virtual reality laparoscopic simulator. Finally, some discussion is raised about the suitability of augmented reality applications around this surgical gesture.

Heller Myotomy for Achalasia: Quality of Life Comparison of Laparoscopic and Open Approaches

Katilius, Marius

2001-01-01

Background: Achalasia is a relatively rare disorder with a variety of treatment options. Although laparoscopic Heller myotomy has become the surgical treatment of choice, little data exist on the overall quality of life of patients undergoing this technique versus standard open approaches. Methods: We prospectively evaluated all patients surgically treated for achalasia by a single surgeon. Laparoscopic Heller myotomy consisted of a long (≥ 6 cm) esophageal cardiomyotomy extending at least 2 cm onto the gastric cardia, with a concomitant Dor fundoplication. Patients were evaluated preoperatively and postoperatively for symptoms and quality of life using the SF-36, a standardized, generic quality of life instrument. Results: A total of 23 patients were surgically treated: 15 patients had a planned laparoscopic procedure, with 3 conversions; 8 had planned open procedures. Dysphagia resolved in 20 of 21 patients, with 1 patient in the laparoscopic group requiring reoperation due to an inadequate gastric myotomy. Compared with preoperative scores, a statistically significant improvement occurred in the general health domain of the SF-36 (70 to 82, P = 0.04). Compared with that in patients undergoing open surgery, the laparoscopic group had better scores in the domains of physical functioning and bodily pain. Conclusions: Laparoscopic Heller myotomy has comparable success to open Heller myotomy, and causes less early detriment to quality of life. This should be the primary treatment in all fit surgical patients with achalasia. PMID:11548827

Full Text Available This study aimed to evaluated laparoscopic ureterocalicostomy as treatment of experimental ureteropelvic junction (UPJ obstruction in pigs. Ten male Large White pigs weighting approximately 28.4 (±1.43 kg were used in the current study. The UPJ obstruction was created laparoscopically by double-clipping of the left ureter. After 14 days the animals underwent laparoscopic ureterocalicostomy f The animals were sacrificed for subsequent retrograde pyelography in order to assess the anastomotic patency on the 28th day. The laparoscopic procedure for experimental obstruction of UPJ was successfully performed in all animals, as well as the laparoscopic ureterocalicostomy. There was intestinal iatrogenic injury in one animal. Satisfactory UPJ patency was noted in 75% of the animals. There was no stenosis of the proximal anastomosis between the ureter and the lower pole of the kidney in 37.5%, mild stenosis in 37.5% and severe stenosis in 25% of the animals. The laparoscopic approach for reestablishment he urinary flow by ureterocalicostomy was feasible in the porcine model. The ascending pyelography revealed satisfactory results of the laparoscopic ureterocalicostomy

Laparoscopic pectopexy: initial experience of single center with a new technique for apical prolapse surgery

Directory of Open Access Journals (Sweden)

Ahmet Kale

Full Text Available ABSTRACT Objective: To share our first experience with laparoscopic pectopexy, a new technique for apical prolapse surgery, and to evaluate the feasibility of this technique. Materials and Methods: Seven patients with apical prolapse underwent surgery with laparoscopic pectopexy. The lateral parts of the iliopectineal ligament were used for a bilateral mesh fixation of the descended structures. The medical records of the patients were reviewed, and the short-term clinical outcomes were analyzed. Results: The laparoscopic pectopexy procedures were successfully performed, without intraoperative and postoperative complications. De novo apical prolapse, de novo urgency, de novo constipation, stress urinary incontinence, anterior and lateral defect cystoceles, and rectoceles did not occur in any of the patients during a 6-month follow-up period. Conclusion: Although laparoscopic sacrocolpopexy has shown excellent anatomical and functional long-term results, laparoscopic pectopexy offers a feasible, safe, and comfortable alternative for apical prolapse surgery. Pectopexy may increase a surgeon's technical perspective for apical prolapse surgery.

The mean operation time was 59.5 ± 20.0 and 39.5 ± 17.5 minutes, respectively, in Groups 1 and 2 (P P P >0.05. Conclusions Early ligature using fast access to the renal vessels during retroperitoneal laparoscopic radical nephrectomy contributed to less operation time and intraoperative blood loss compared with the previous technique. In addition, the modified technique permits the procedure to be performed following the principles of open radical nephrectomy.

Full Text Available Context: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. Aims: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. Settings and Design: Prospective descriptive study. Materials and Methods: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. Statistical Analysis Used: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. Results: Of the 570 patients undergoing laparoscopic surgery, 17 (3% had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI was the most frequent (n = 10, 1.8%, followed by port site bleeding (n = 4, 0.7%, omentum-related complications (n = 2; 0.35%, and port site metastasis (n = 1, 0.175%. Conclusions: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.

Analgesic effect of bilateral subcostal tap block after laparoscopic cholecystectomy

International Nuclear Information System (INIS)

Karam, K.; Khan, B.I.

2018-01-01

Pain after laparoscopic cholecystectomy is mild to moderate in intensity. Several modalities are employed for achieving safe and effective postoperative analgesia, the benefits of which adds to the early recovery of the patients. As a part of multimodal analgesia, various approaches of Transversus abdominis plane (TAP) block has been used for management of parietal and incisional components of pain after laparoscopic cholecystectomy. This study was designed to compare the analgesic efficacy of two different approaches of ultrasound guided TAP block, i.e., Subcostal-TAP block technique with ultrasound guided Posterior-TAP block for post-operative pain management in patients undergoing laparoscopic cholecystectomy under general anaesthesia. Methods: In this double blinded randomized controlled study, consecutive nonprobability sampling was done and a total of 126 patients admitted for elective laparoscopic cholecystectomy fulfilling the inclusion criteria were selected. After induction of general anaesthesia, patients were randomized through draw method and received either ultrasound guided posterior TAP block with 0.375% bupivacaine (20ml volume) on each side of the abdomen or subcostal TAP block bilaterally with the same. Up to 24 hours postoperatively, static and dynamic numeric rating pain scores were assessed. Results: We found statistically significant difference in mean static pain scores over 24 hours postoperatively in subcostal TAP group, suggesting improved analgesia. However, mean dynamic postoperative pain scores were comparable between the two groups. Whereas, patients in both groups were satisfied with pain management. Conclusions: Ultrasound guided subcostal TAP block provides better postoperative analgesia as compared to the Posterior TAP block in laparoscopic cholecystectomy. Otherwise both of the approaches improve patient outcomes towards early recovery and discharge from hospital. (author)

2016-11-01

Laparoscopic anti-reflux surgery is conventionally performed using two 10/12 mm ports. While laparoscopic procedures reduce post-operative pain, the use of larger ports invariably increases discomfort and affects cosmesis. We describe a new all 5 mm ports technique for laparoscopic anti-reflux surgery and present a review of our initial experience with this approach. All patients undergoing laparoscopic fundoplication over a 35 month period from February 2013 under the care of a single surgeon were included. A Lind laparoscopic fundoplication was performed using an all 5 mm port technique. Data was recorded prospectively on patient demographics, operating surgeon, surgical time, date of discharge, readmissions, complications, need for re-intervention, and reasons for admission. Two hundred and five consecutive patients underwent laparoscopic fundoplication over the study period. The all 5 mm port technique was used in all cases, with conversion to a 12 mm port only once (0.49%). Median operating time was 52 min 185 (90.2%) patients were discharged as day cases. Increasing ASA grade and the presence of a hiatus hernia were associated with the need for overnight stay with admission required in 33% of patients with ASA 3, compared to 4% with ASA 1 (p = 0.001), and 29% of those with a hiatus hernia vs. 5% without (p management. This would improve the service for these patients and culminate in cost savings for the NHS. Copyright © 2016. Published by Elsevier Ltd.

The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

Extramucosal pancreaticojejunostomy at laparoscopic pancreaticoduodenectomy

Directory of Open Access Journals (Sweden)

Servet Karagul

2018-01-01

Full Text Available While the 'best pancreatic anastomosis technique' debate is going during Whipple procedure, the laparoscopic pancreaticoduodenectomy lately began to appear more and more often in the medical literature. All the popular anastomosis techniques used in open pancreas surgery are being experienced in laparoscopic pancreaticoduodenectomy. However, when they were adapted to laparoscopy, their implementation was not technically easy, and assistance of robotic surgery was sometimes required at the pancreatic anastomosis stage of the procedure. Feasibility and simplicity of a new technique have a vital role in its adaptation to laparoscopic surgery. We frequently use the extra-mucosal single row handsewn anastomosis method in open and laparoscopic surgery of the stomach, small and large bowel and we found it easy and reliable. Here, we defined the adaptation of this technique to the laparoscopic pancreas anastomosis. The outcomes were not inferior to the other previously described techniques and it has the advantage of simplicity.

The risk of port-site metastasis after laparoscopic removal of incidental gallbladder cancer was previously estimated to be 14-30%. The present study was designed to determine the incidence of port-site metastasis in incidental gallbladder cancer in the modern era (2000-2014) versus the historic era (1991-1999). We also investigated the site of port-site metastasis. Using PRISMA, a systematic review was conducted to identify papers that addressed the development of port-site metastasis after laparoscopic resection of incidental gallbladder cancer. Studies that described cancer-specific outcomes in ≥5 patients were included. A validated quality appraisal tool was used, and a weighted estimate of the incidence of port-site metastasis was calculated. Based on data extracted from 27 papers that met inclusion criteria, the incidence of port-site metastasis in incidental gallbladder cancer has decreased from 18.6% prior to 2000 (95% confidence interval 15.3-21.9%, n = 7) to 10.3% since then (95% confidence interval 7.9-12.7%, n = 20) (P extraction site is at significantly higher risk than nonextraction sites. The incidence of port-site metastasis in incidental gallbladder cancer has decreased but remains high relative to other primary tumors. Any preoperative finding that raises the suspicion of gallbladder cancer should prompt further investigation and referral to a hepato-pancreato-biliary specialist. Copyright © 2016 Elsevier Inc.

Operative repair of obstructive gastric volvulus is challenging. In high-operative risk patients with obstructive gastric volvulus, we perform laparoscopic reduction of gastric volvulus and anterior abdominal wall sutured gastropexy. This case series reports our experience with this operation. We reviewed the charts of all patients who presented with obstructive gastric volvulus and underwent laparoscopic gastropexy between 2007 and 2013. Eleven patients underwent laparoscopic gastropexy. Median age was 83 years (50 to 92). Six patients presented with chronic obstruction; 5 presented with acute obstruction. Median postoperative hospitalization was 2 days (1 to 39). Two patients required reoperation for displaced gastrostomy tubes. At median follow-up of 3 months (2 weeks to 57 months), all patients remained free of gastric obstructive symptoms and recurrent episodes of volvulus. Only 1 patient received nutrition via gastrostomy tube. Laparoscopic gastropexy can treat obstructed gastric volvulus in highoperative risk patients. Because of associated morbidity, gastrostomy tubes should be placed selectively. Copyright © 2015 Elsevier Inc. All rights reserved.

Surgical Treatment for Achalasia of the Esophagus: Laparoscopic Heller Myotomy

Torres-Villalobos, Gonzalo; Martin-del-Campo, Luis Alfonso

2013-01-01

Achalasia is an esophageal motility disorder that leads to dysphagia, chest pain, and weight loss. Its diagnosis is clinically suspected and is confirmed with esophageal manometry. Although pneumatic dilation has a role in the treatment of patients with achalasia, laparoscopic Heller myotomy is considered by many experts as the best treatment modality for most patients with newly diagnosed achalasia. This review will focus on the surgical treatment of achalasia, with special emphasis on laparoscopic Heller myotomy. We will also present a brief discussion of the evaluation of patients with persistent or recurrent symptoms after surgical treatment for achalasia and emerging technologies such as LESS, robot-assisted myotomy, and POEM.

The development of laparoscopic hernia repair has provided an alternative approach to the management of incarcerated inguinal hernia in children. Different laparoscopic techniques for hernia repair have been described. However, we hereby review the role of laparoscopic hernia repair using the hook method in the emergency setting for incarcerated inguinal hernias in children. A retrospective review was conducted of all children who presented with incarcerated inguinal hernia and underwent laparoscopic hernia repair using the hook method in emergency setting between 2004 and 2010. There were a total of 15 boys and 1 girl with a mean age of 30 ± 36 months (range, 4 months to 12 years). The hernia was successfully reduced after sedation in 7 children and after general anesthesia in 4 children. In 5 children, the hernia was reduced by a combined manual and laparoscopic-assisted approach. Emergency laparoscopic inguinal hernia repair using the hook method was performed after reduction of the hernia. The presence of preperitoneal fluid secondary to recent incarceration facilitated the dissection of the preperitoneal space by the hernia hook. All children underwent successful reduction and hernia repair. The median operative time was 37 minutes. There was no postoperative complication. The median hospital stay was 3 days. At a median follow-up of 40 months, there was no recurrence of the hernia or testicular atrophy. Emergency laparoscopic inguinal hernia repair by the hook method is safe and feasible. Easier preperitoneal dissection was experienced, and repair of the contralateral patent processus vaginalis can be performed in the same setting. Copyright © 2011 Elsevier Inc. All rights reserved.

Several studies have demonstrated that laparoscopic colonic resection has significant benefits in comparison with open approaches in patients with benign and malignant disease. The proportion of colonic and rectal resections conducted laparoscopically in Austria is not currently known; the aim of this study was to evaluate the current status of laparoscopic colonic surgery in Austria. A questionnaire was distributed to all general surgical departments in Austria. In collaboration with IMAS, an Austrian market research institute, an online survey was used to identify laparoscopic and open colorectal resections performed in 2013. The results were compared with data from the National Hospital Morbidity Database (NHMD), in which administrative in-patient data were also collected from all general surgical departments in Austria in 2013. Fifty-three of 99 surgical departments in Austria responded (53.5%); 4335 colonic and rectal resections were carried out in the participating departments, representing 50.5% of all NHMD-recorded colorectal resections (n = 8576) in Austria in 2013. Of these 4335 colonic and rectal resections, 2597 (59.9%) were carried out using an open approach, 1674 (38.6%) were laparoscopic, and an exact classification was not available for 64 (1.5%). Among the NHMD-recorded colonic and rectal resections, 6342 (73.9%) were carried out with an open approach, and 2234 (26.1%) were laparoscopic. The proportion of colorectal resections that are carried out laparoscopically is low (26.1%). Technical challenges and a learning curve with a significant number of cases may be reasons for the slow adoption of laparoscopic colonic surgery.

New technological advances have enabled the development of single-port laparoscopic surgery. This approach began with cholecystectomy and subsequently with other abdominal surgeries. However, few publications on laparoscopic liver surgery have described the use of complete single-port access. We present our initial experience of a single-port laparoscopic hepatectomy. Between May 2012 and December 2013, 5 single-port laparoscopic hepatectomies were performed: one for benign disease and four for colorectal liver metastases. The lesions were approached through a 3-5 cm right supraumbilical incision using a single-port access device. All the lesions were located in hepatic segments II or III. Four left lateral sectorectomies and one left hepatectomy were performed. Median operative time was 135 min. No cases were converted to conventional laparoscopic or open surgery. The oral intake began at 18 h. There were no postoperative complications and no patients required blood transfusion. The median hospital stay was 3 days. The degree of satisfaction was very good in 4 cases and good in one. Patients resumed their normal daily activities at 8 days. Single-port laparoscopic hepatectomy is safe and feasible in selected cases and may reduce surgical aggression and offer better cosmetic results. Comparative studies are needed to determine the real advantages of this approach. Copyright © 2014 AEC. Published by Elsevier Espana. All rights reserved.

Laparoscopic Heller myotomy for achalasia: changing trend toward "true" day-case procedure.

Science.gov (United States)

Agrawal, Sanjay; Super, Paul

2008-12-01

Laparoscopic Heller myotomy is the most effective therapy for achalasia. All case series have reported a minimum length of stay of more than 1 day. "True" day-case laparoscopic Heller myotomy has not been reported, so far. The aim of this study was to review our results with laparoscopic Heller myotomy with respect to the length of stay following the procedure. All patients undergoing laparoscopic Heller myotomy between August 2000 and July 2007 under the care of one surgeon were included in the study. This was performed by incising 6 cm of distal esophageal musculature, extending to 2 cm below the gastroesophageal junction. The myotomy was covered by an anterior fundoplication. All patients were reviewed in the clinic at a median of 6 weeks after surgery and, thereafter, if necessary. Over the 7-year period, 24 consecutive patients with achalasia were treated in this manner. There were 13 women and 11 men, with an age range of 12-73 years. Intraoperative complications included mucosal perforation in 2 patients (sutured immediately) with no postoperative complications or conversion to open surgery. There were no deaths. The average length of stay was 1.9 days (range, 0-4). The last 2 patients were discharged on the same day, and the 5 previous to this were discharged within 23 hours of surgery. There were no adverse outcomes related to early discharge, and there were no readmissions. All patients reported good to excellent results with a relief of dysphagia on follow-up. Three patients (12%) developed recurrent dysphagia after an initial improvement, requiring dilatation only several months later. Based on our own experience, we believe that laparoscopic Heller myotomy with anterior partial fundoplication is safe and achieves a good outcome in the treatment of achalasia. It is well tolerated and can be considered a true day-case procedure.

The aim of this study is to compare Holmium laser enucleation of the prostate with another minimally invasive technique, the laparoscopic simple prostatectomy. We compared outcomes of a series of 40 patients who underwent laparoscopic simple prostatectomy (n=20) with laser enucleation of the prostate (n=20) for large adenomas (>100 grams) at our institution. Study variables included operative time and catheterization time, hospital stay, pre- and post-operative International Prostate Symptom Score and maximum urinary flow rate, complications and economic evaluation. Statistical analyses were performed using the Student t test and Fisher test. There were no significant differences in patient age, preoperative prostatic size, operating time or specimen weight between the 2 groups. Duration of catheterization (P=.0008) and hospital stay (P.99). Holmium enucleation of the prostate has similar short term functional results and complication rates compared to laparoscopic simple prostatectomy performed in large glands with the advantage of less catheterization time, lower economic costs and a reduced hospital stay.

2010-08-01

Studies using conventional consoles have suggested a possible link between video-gaming and laparoscopic skill. The authors hypothesized that the Nintendo Wii, with its motion-sensing interface, would provide a better model for laparoscopic tasks. This study investigated the relationship between Nintendo Wii skill, prior gaming experience, and laparoscopic skill. In this study, 20 participants who had minimal experience with either laparoscopic surgery or Nintendo Wii performed three tasks on a Webcam-based laparoscopic simulator and were assessed on three games on the Wii. The participants completed a questionnaire assessing prior gaming experience. The score for each of the three Wii games correlated positively with the laparoscopic score (r = 0.78, 0.63, 0.77; P skill overlap between the Nintendo Wii and basic laparoscopic tasks. Surgical candidates with advanced Nintendo Wii ability may possess higher baseline laparoscopic ability.

To investigate whether a virtual reality simulator (LapSim) and traditional box trainer are effective tools for the acquisition of basic laparoscopic skills, and whether the LapSim is superior to the box trainer in surgical education. In a study at Ege University School of Medicine, Izmir, Turkey, between September 2008 and March 2013, 40 first- and second-year residents were randomized to train via the LapSim or box trainer for 4 weeks, and 20 senior residents were allocated to a control group. All 3 groups performed laparoscopic bilateral tubal ligation. Video records of each operation were assessed via the general rating scale of the Objective Structured Assessment of Laparoscopic Salpingectomy and by operation time in seconds. Compared with the control group, the LapSim and box trainer groups performed significantly better in total score (Peducation. Training with a virtual reality simulator or box trainer should be considered before actual laparoscopic procedures are carried out.

There is conflicting evidence for the use of warmed, humidified carbon dioxide (CO2) for creating pneumoperitoneum during laparoscopic cholecystectomy. Few studies have reported less post-operative pain and analgesic requirement when warmed CO2 was used. This systematic review and meta-analysis aims to analyse the literature on the use of warmed CO2 in comparison to standard temperature CO2 during laparoscopic cholecystectomy. Systematic review and meta-analysis carried out in line with the PRISMA guidelines. Primary outcomes of interest were post-operative pain at 6 h, day 1 and day 2 following laparoscopic cholecystectomy. Secondary outcomes were analgesic usage and drop in intra-operative core body temperature. Standard Mean Difference (SMD) was calculated for continuous variables. Six randomised controlled trials (RCTs) met the inclusion criteria (n = 369). There was no significant difference in post-operative pain at 6 h [3 RCTs; SMD = -0.66 (-1.33, 0.02) (Z = 1.89) (P = 0.06)], day 1 [4 RCTs; SMD = -0.51 (-1.47, 0.44) (Z = 1.05) (P = 0.29)] and day 2 [2 RCTs; SMD = -0.96 (-2.30, 0.37) (Z = 1.42) (P = 0.16)] between the warmed CO2 and standard CO2 group. There was no difference in analgesic usage between the two groups, but pooled analysis was not possible. Two RCTs reported significant drop in intra-operative core body temperature, but there were no adverse events related to this. This review showed no difference in post-operative pain and analgesic requirements between the warmed and standard CO2 insufflation during laparoscopic cholecystectomy. Currently there is not enough high quality evidence to suggest routine usage of warmed CO2 for creating pneumoperitoneum during laparoscopic cholecystectomy.

In the late '80s the successes of the laparoscopic surgery for gallbladder disease laid the foundations on the modern use of this surgical technique in a variety of diseases. In the last 20 years, laparoscopic colorectal surgery had become a popular treatment option for colorectal cancer patients. Many studies emphasized on the benefits stating the significant advantages of the laparoscopic approach compared with the open surgery of reduced blood loss, early return of intestinal motility, lower overall morbidity, and shorter duration of hospital stay, leading to a general agreement on laparoscopic surgery as an alternative to conventional open surgery for colon cancer. The reduced hospital stay may also decrease the cost of the laparoscopic surgery for colorectal cancer, despite th higher operative spending compared with open surgery. The average reduction in total direct costs is difficult to define due to the increasing cost over time, making challenging the comparisons between studies conducted during a time range of more than 10 years. However, despite the theoretical advantages of laparoscopic surgery, it is still not considered the standard treatment for colorectal cancer patients due to technical limitations or the characteristics of the patients that may affect short and long term outcomes. The laparoscopic approach to colectomy is slowly gaining acceptance for the management of colorectal pathology. Laparoscopic surgery for colon cancer demonstrates better short-term outcome, oncologic safety, and equivalent long-term outcome of open surgery. For rectal cancer, laparoscopic technique can be more complex depending on the tumor location. The advantages of minimally invasive surgery may translate better care quality for oncological patients and lead to increased cost saving through the introduction of active enhanced recovery programs which are likely cost-effective from the perspective of the hospital health-care providers.

Full Text Available Noninvasive ventilation has been shown to reduce acute postoperative hypoxaemia, with significant reduction in the incidence of re-intubation, complications and a trend towards lower mortality. The aim of the study was to determine the effectiveness of CPAP vs venturi therapy in early achievement of oxygenation goals and in prevention of re-intubation for management of postoperative hypoxaemia following laparoscopic cholecystectomy. Forty adult patients of ASA physical status I& II, scheduled for elective laparoscopic cholecystectomy, those were unable to maintain SpO2 > 95% breathing room air after extubation, were recruited for a prospective, randomized comparative study. Patients with PaO2 / FiO2 between 250 and 300 were included in the study and were randomly allocated to one of the two groups to receive oxygen therapy either using a CPAP of 10 cm of water and a FiO2 of 0.5 (Group A or using a venturi mask of FiO2 of 0.5 (Group B . All patients were observed postoperatively upto 18 h and were screened by ABG analyses at 6, 12 and 18 h of treatment. SpO2, ECG, heart rate, respiratory rate, temperature and NIBP were monitored throughout the study period. Patients in Group A showed significant improvement in early achievement of adequate oxygenation than those in Group B, although, due to intolerance to CPAP therapy two patients in Group A needed reintubation to maintain adequate oxygenation. To conclude, oxygenation using continuous positive airway pressure is a safe and effective means in improving gas exchange to treat acute postoperative hypoxaemia in conscious and cooperative patients.

Previous studies have shown that laparoscopic colorectal cancer surgery is highly safe and effective compared to laparotomy. However, whether laparoscopic colorectal cancer surgery can be safely performed in patients with severe comorbidities remains unclear. The aim of this study was to evaluate the safety of laparoscopic colorectal cancer surgery in patients with severe comorbidities. A total of 82 consecutive patients with colorectal cancer who underwent laparoscopic surgery were retrospectively divided into two groups according to whether they had severe comorbidity (50 patients) or non-severe comorbidity (32 patients). An age-adjusted Charlson comorbidity index of ≥6 was defined as severe comorbidity. Operative time, blood loss, and rate of conversion to laparotomy did not differ between the groups. Postoperative complications and the length of the postoperative hospital stay also did not differ significantly between the groups. Laparoscopic colorectal cancer surgery is feasible and safe, even in patients with severe comorbidities. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Full Text Available Surgical pancreatic duct (PD drainage for chronic pancreatitis in children is relatively rare. It is indicated in cases of recurrent pancreatitis and PD dilatation that have not responded to medical therapy and therapeutic endoscopy. We performed laparoscopic side-to-side pancreaticojejunostomy for two paediatric patients with chronic pancreatitis. The main PD was opened easily by electrocautery after locating the dilated PD by intraoperative ultrasonography. The dilated PD was split longitudinally from the pancreatic tail to the pancreatic head by laparoscopic coagulation shears or electrocautery after pancreatography. A laparoscopic side-to-side pancreaticojejunostomy was performed by a one-layered technique using continuous 4-0 polydioxanone (PDS sutures from the pancreatic tail to the pancreatic head. There were no intraoperative or postoperative complications or recurrences. This procedure has cosmetic advantages compared with open surgery for chronic pancreatitis. Laparoscopic side-to-side pancreaticojejunostomy in children is feasible and effective for the treatment of chronic pancreatitis.

We developed the iTrainer (iT) as a portable laparoscopic trainer, which incorporates the iPad tablet. We then compared the iT with a standard pelvic trainer (SPT) to assess surgical skills as well as its image quality, resolution, brightness, comfort, and overall performance. We designed and constructed the iT to be compatible with the Apple iPad 3 and standard laparoscopic instruments. Participants were assigned to perform the thread-the-loops task on both trainers and were prospectively randomized to start on either the iT or the SPT. Each participant was allowed a 2-minute warm-up before the 2-minute testing period. We scored participants using the product of skill quality (0-4 scale) and quantity of loops threaded (0-10 scale). Participants then rated each trainer on image quality, resolution, brightness, comfort, and overall performance on a 5-point Likert scale. A total of 45 subjects including 10 undergraduates, 10 medical students, 10 general surgery and urology residents, and 15 experts (fellows and attending surgeons) participated in this study. There was no significant difference between thread-the-loops task scores completed on the iT when compared with the SPT for all groups tested (p > 0.05) with the exception of the medical student group, who performed better on the SPT (p < 0.05). On evaluation of each trainer, participants rated the iT as having superior image quality and resolution when compared with the SPT (p < 0.05) but rated the SPT higher in overall performance (p < 0.05). Brightness and comfort were rated similarly for both trainers. We have demonstrated face validity and criterion validity for the thread-the-loops task on the iT. The iT rated superior in image quality and resolution but inferior in overall performance compared with the SPT. The iT provides trainees a unique advantage over SPT as an additional resource to laparoscopic training as it is inexpensive, portable, and can be readily available for training. Copyright © 2014

Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013. Patients were classified according to their BMI as obese (BMI 30.0-39.9), morbidly obese (BMI 40.0-49.9), and super obese (BMI >50). Main outcome measures included conversion rate, operative time, estimated blood loss, post-operative complications, and length of stay. There were 923 patients who met inclusion criteria. Overall, 604 (65.4%), 257 (27.9%), and 62 (6.7%) were classified as obese (O), morbidly obese (MO), and super obese (SO), respectively. Clinicopathologic characteristics were similar among the three groups. The SO group had significantly higher conversion rates (17.7 vs. 7 vs. 4.8%; P = 0.031), longer average hospital stays (7.1 days vs. 4.9 vs. 3.4; P = 0.001), higher morbidity (40.3 vs. 16.3 vs. 12.4%; P = 0.001), and longer operative times (206 min vs. 184 vs. 163; P = 0.04) compared to the MO and O groups, respectively. The anastomotic leak rate in the SO (4.8%; P = 0.027) and MO males (4.1%; P = 0.033) was significantly higher than MO females (2.2%) and all obese patients (1.8%). Increasing severity of obesity is associated with worse perioperative outcomes following laparoscopic colectomy.

This study aimed to evaluate laparoscopic dismembered pyeloplasty compared with open surgery and to determine whether the morbidity and outcome rates are different in each of these techniques. We report our 10-year experience with open and laparoscopic pyeloplasty at one istitution. From February 1999 to October 2010, 49 patients with ureteropelvic junction obstruction were assigned into two groups. 25 patients underwent open surgical pyeloplasty (period 1999-2010) and 24 underwent laparoscopic pyeloplasty (period 2004-2010). 25 patients undergoing open pyeloplasty had a retroperitoneal flank approach. Of the 24 laparoscopic cases 18 had a transperitoneal retrocolic access, 1 had a transperitoneal transmesocolic access and 5 had a retroperitoneal access. In all 49 cases an Anderson-Hynes dismembered pyeloplasty was used. We retrospectively compared the operative time, hospital stay, perioperative complications and follow-up of the two groups. Clinical symptoms were assessed before and after surgery, subjectively. Patients dermographic data were similar between the two groups with mean age of 42 years (range 6-78) and with a male/female ratio of 1:1.45. A crossing vessel could be identified in 37.5% (9/24) with laparoscopy vs. 32% (8/25) in open surgery. Compared with open procedures, laparoscopic procedures were associated with a longer mean operating time (274 vs 143 min), a shorter mean hospital stay (9.9 vs 15.8 day) and the perioperative complication rates were 16.7% for laparoscopic pyeloplasties and 20% for open pyeloplasties. The success rates were 90.5% for laparoscopy and 90.9% for open surgery. Average follow-up was 40.9 month for the laparoscopic group and 72.3 month for the open group. Failed procedures showed no improvement in loin pain or obstruction. The efficacy (in term of success rate and perioperative complications) of laparoscopic pyeloplasty is comparable to that of open pyeloplasty, with shorter mean hospital stay and better cosmetic results

While robotic assisted radical nephrectomy is safe with outcomes and complication rates comparable to those of the pure laparoscopic approach, there is little evidence of an economic or clinical benefit. From the 2009 to 2011 Nationwide Inpatient Sample database we identified patients 18 years old or older who underwent radical nephrectomy for primary renal malignancy. Robotic assisted and laparoscopic techniques were noted. Patients treated with the open technique and those with evidence of metastatic disease were excluded from analysis. Descriptive statistics were performed using the chi-square and Mann-Whitney tests, and the Student t-test. Multiple linear regression was done to examine factors associated with increased hospital costs and charges. We identified 24,312 radical nephrectomy cases for study inclusion, of which 7,787 (32%) were performed robotically. There was no demographic difference between robotic assisted and pure laparoscopic radical nephrectomy cases. Median total charges were $47,036 vs $38,068 for robotic assisted vs laparoscopic surgery (p robotic assisted surgery were $15,149 compared to $11,735 for laparoscopic surgery (p robotic assistance conferred an estimated $4,565 and $11,267 increase in hospital costs and charges, respectively, when adjusted for adapted Charlson comorbidity index score, perioperative complications and length of stay (p Robotic assisted radical nephrectomy results in increased medical expense without improving patient morbidity. Assuming surgeon proficiency with pure laparoscopy, robotic technology should be reserved primarily for complex surgeries requiring reconstruction. Traditional laparoscopic techniques should continue to be used for routine radical nephrectomy. Copyright © 2014 American Urological Association Education and Research, Inc.

Laparoscopic myotomy: technique and efficacy in treating achalasia.

Science.gov (United States)

Ali, A; Pellegrini, C A

2001-04-01

Esophageal Heller myotomy and a partial antireflux procedure for achalasia are the ideal procedures to benefit from the advances in minimally invasive surgery. The magnified view of the operative field provided by the laparoscope allows precise division of the esophageal muscle fibers with excellent results. Laparoscopic Heller myotomy results in reduced postoperative pain, less morbidity, shorter hospitalization, better resolution of dysphagia, and less postoperative heartburn when compared with the open abdominal and even the thoracoscopic approach. A longer myotomy especially at the distal end, and a loose, well-formed partial fundoplication are the keys to a successful outcome. Superior long-term results after surgical myotomy when compared with nonsurgical interventions argue strongly in favor of surgery in any patient who is fit enough to undergo general anesthesia.

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

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

Full Text Available Background. Controversies on the utility of laparoscopic mini gastric bypass (LMGB in weight loss and type 2 diabetes mellitus (T2DM control still exist. Methods. We conducted a comprehensive literature search of PubMed, EMBASE, and Cochrane Library. Review Manager was used to perform the meta-analysis and the weighted mean difference (WMD and/or odds ratio with 95% confidence interval (95% CI were used to evaluate the overall size effect. Results. The literature search identified 16 studies for systematic review and 15 articles for meta-analysis. Compared with LAGB, LSG, and LRYGB, LMGB showed significant weight loss [WMD, −6.58 (95% CI, −9.37, −3.79, P<0.01 (LAGB; 2.86 (95% CI, 1.40, 5.83, P=0.004 (LSG; 10.33 (95% CI, 4.30, 16.36, P<0.01 (LRYGB] and comparable/higher T2DM remission results [86.2% versus 55.6%, P=0.06 (LAGB; 89.1% versus 76.3%, P=0.004 (LAGB; 93.4% versus 77.6%, P=0.006 (LAGB]; LMGB also had shorter learning curve and less operation time than LRYGB [WMD, −35.2 (95% CI, −46.94, −23.46]. Conclusions. LMGB appeared to be effective in weight loss and T2DM remission and noninferior to other bariatric surgeries. However, clinical utility of LMGB needs to be further validated by future prospective randomized controlled trials.

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