Trocar number and placement for laparoscopic sleeve gastrectomy and comparison of single-incision and conventional laparoscopic sleeve gastrectomy: a systematic review and meta-analysis. Int J Surg 2023; 109:1783-1795. [PMID: 37068794 PMCID: PMC10389429 DOI: 10.1097/js9.0000000000000402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 04/06/2023] [Indexed: 04/19/2023]
Abstract
BACKGROUND Conventional laparoscopic sleeve gastrectomy (CLSG) has been conducted in multiple centers for treating morbid obesity, however, there are no standard criteria for (1) placing the trocar; and (2) how many trocars should be used. Single-incision laparoscopic sleeve gastrectomy (SLSG), a newly emerged technique in 2008, has been proposed as an alternative to CLSG in recent years, however, there is no definite evidence for this. MATERIALS AND METHODS A systematic literature search was performed using the PubMed, Embase, Web of Science, and Cochrane Library databases for laparoscopic sleeve gastrectomy cases from January 2006 to October 2022. We then summarized the trocar numbers and placement patterns among these studies. A meta-analysis was conducted to compare the difference between SLSG and CLSG in the perioperative and postoperative indices. RESULTS A total of 61 studies involving 20 180 patients who underwent laparoscopic sleeve gastrectomy for treating morbid obesity were included in the systematic review, including 11 on SLSG, 35 on CLSG, and 15 studies comparing SLSG and CLSG. A systematic review showed that the trocar number varied in different CLSG studies, mainly using four or five trocars. The trocars were mainly placed in position, presenting an inverted trapezoid pattern and a left-predominant pattern. Meta-analysis showed that the operative time in the SLSG was significantly higher than that in the CLSG, and the pain Visual Analog Scale rating on postoperative day 1 in the CLSG was significantly higher than in the SLSG. There were no statistical significances in the other complications or surgical efficiency. CONCLUSIONS In the CLSG, the majority of the trocars were arranged in an inverted trapezoid pattern and were of the left-predominant type. Although SLSG is a feasible technique in selected patients, there is insufficient evidence to recommend its widespread use compared with CLSG. High-quality randomized controlled trials with large study populations and long follow-up periods will be required in the future.

Outcomes of metabolic surgery in obese patients with type 2 diabetes with respect to impact on beta cell function, insulin sensitivity and diabetes remission - A study from south India. Diabetes Metab Syndr 2020; 14:1829-1835. [PMID: 32961515 DOI: 10.1016/j.dsx.2020.09.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 09/05/2020] [Accepted: 09/07/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND AIMS Metabolic surgery is gaining popularity as a procedure for the treatment of morbid obesity among patients with type 2 diabetes (T2DM). The aim of the study was to evaluate the effects of metabolic surgery on beta cell function, insulin sensitivity and glycemic status in obese Asian Indian patients. METHODS This is a prospective study of 26 patients with T2DM who underwent metabolic surgery. Complete diabetes remission was defined as FPG<100 mg/dl and HbA1c < 6%, without antidiabetic medications one-year post surgery. Anthropometry, HOMA-IR (insulin resistance), HOMA-insulin sensitivity, beta cell function and antidiabetic drug usage were measured at baseline, 6 months and 12 months post-surgery. RESULTS The overall duration of diabetes was 10.3 ± 5.4 years. At one year, 7 (27%) of 26 T2DM patients, achieved diabetes remission while the other 19 had improvement in diabetes status. ROC curves showed that those who had diabetes duration <8.5 years achieved remission. There was a significant decrease in HOMA-IR [3.7 ± 1.8 vs 1.4 ± 0.9 vs1.2 ± 0.6, p < 0.001] and improvement in HOMA-Insulin sensitivity [34 ± 17 vs 93 ± 50 vs 112 ± 62, p < 0.001] from baseline to 6 and 12 months post-surgery respectively. There was a significant (p < 0.001) reduction in the usage of anti-diabetes medications post-surgery. The limitations of this study are small sample size and limited follow up period of 1 year. CONCLUSIONS Among T2DM patients, metabolic surgery resulted in significant improvement in beta cell function and insulin sensitivity along with reduction in anti-diabetes medication. Diabetes remission was mainly seen in those who had duration of diabetes <8.5 years.

Abstract
PURPOSE Both laparoscopic sleeve gastrectomy (LSG) and liraglutide cause a significant weight loss. We evaluated the effect of liraglutide in comparison with placebo on total weight loss (TWL) and excess body weight loss (EWL) and when added in initial weight loss period after LSG in obese individuals. MATERIAL AND METHODS Participants with BMI > 30 kg/m2 undergoing LSG were randomised to receive either liraglutide (subcutaneous) in increasing does of 0.6 mg/day until maximum tolerated dose of 3.0 mg (L-L group) or placebo (L-P group) from 6 weeks post-operative until 6 months. Weight, BMI, %TWL, %EWL, HbA1c, fasting plasma glucose, HOMA-IR, resolution of type 2 diabetes mellitus, hypertension, dyslipidaemia, sleep apnea and quality of life were evaluated. Primary end point was %TWL and % EWL at post-operative 6 months. RESULTS Thirty participants underwent LSG, and 23 were randomised to receive liraglutide (n = 12) or placebo (n = 11).The mean dose of liraglutide in L-L group was 1.41 ± 0.49 mg/day. Patients in L-L group had %TWL of 28.2 ± 5.7 and %EWL of 58.7 ± 14.3 as compared with 23.2 ± 6.2 (p = 0.116) and 44.5 ± 8.6 (p = 0.043) in L-P group at 24 weeks, respectively. BMI decreased by 11.7 ± 3.5 in L-L group compared with 9.5 ± 4.0 in L-P group (p = 0.287). All patients with diabetes or pre-diabetes had resolution of dysglycemia in the L-L group as compared with 50% in L-P group. However, there was no significant difference in resolution of other obesity-related comorbidities between two groups at 24-week follow-up. CONCLUSION Liraglutide added early after LSG significantly augments weight loss from LSG in obese individuals. TRIAL REGISTRATION The study protocol was registered at clinical trials.gov.in with NCT: 04325581.

Abstract
INTRODUCTION Increasing incidence of obesity in Indian population has led to an exponential rise in the number of bariatric operations performed annually. Laparoscopic Sleeve Gastrectomy (LSG) has been proposed to cause rapid remission of Type 2 Diabetes Melitus (T2DM) and metabolic syndrome in a weight loss independent manner. AIM To evaluate the effects of LSG on metabolic syndrome and central obesity in morbidly and severely obese Indian adults. Material and Methods: Study was conducted on 91 morbidly obese [Body Mass Index (BMI)>40 kg/m2] and severely obese (BMI>35 kg/m2) individuals who were suffering from diabetes, hypertension or dyslipidemia. The patients were followed up for six months and the trends of glycaemic control, mean blood pressure, lipid profile, weight loss parameters and changes in parameters of central obesity were studied. RESULTS Weight loss was significant at three months postsurgery and was sustained through six months. There was significant improvement in glycaemic control leading to reduction in need for oral hypoglycaemic agents or insulin in majority of them and even discontinuation of these medications in few patients. Hypertension and dyslipidemia also showed an improving trend through six months postsurgery. There was a significant impact on reduction of central obesity in these patients as marked by significant reduction in waist to hip ratio. CONCLUSION LSG produces sustainable weight loss with significant improvement in glycaemic status and control of metabolic syndrome in severe to morbidly obese patients. LSG is also efficacious in reducing central obesity in Indian population which is a major depressive ailment amongst obese individuals.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) was initially performed as the first stage of biliopancreatic diversion with duodenal switch for the treatment of super-obese or high-risk obese patients but is now most commonly performed as a standalone operation. The aim of this prospective study was to investigate outcomes after LSG according to resected stomach volume. METHODS Between May 2011 and April 2013, LSG was performed in 102 consecutive patients undergoing bariatric surgery. Two patients were excluded, and data from the remaining 100 patients were analyzed in this study. Patients were divided into three groups according to the following resected stomach volume: 700-1,200 mL (group A, n = 21), 1,200-1,700 mL (group B, n = 62), and >1,700 mL (group C, n = 17). Mean values were compared among the groups by analysis of variance. RESULTS The mean percentage excess body weight loss (%EBWL) at 3, 6, 12, and 24 months after surgery was 37.68 ± 10.97, 50.97 ± 13.59, 62.35 ± 11.31, and 67.59 ± 9.02 %, respectively. There were no significant differences in mean %EBWL among the three groups. Resected stomach volume was greater in patients with higher preoperative body mass index and was positively associated with resected stomach weight. CONCLUSIONS Mean %EBWL after LSG was not significantly different among three groups of patients divided according to resected stomach volume. Resected stomach volume was significantly greater in patients with higher preoperative body mass index.

Abstract
BACKGROUND Bariatric surgery has been established as the best option of treatment for morbid obesity. Recently, laparoscopic sleeve gastrectomy (SG) has become very popular because of good postoperative weight loss and low morbidity. The aim of this study was to report our single-center experience with SG regarding feasibility, morbidity, and outcome. METHODS From January 2006 to December 2011, 93 patients (68 female) with a median age of 46 years underwent laparoscopic SG at our department. Thirteen patients had a history of gastric banding with insufficient weight loss or band-related complications. Clinical outcome and laboratory findings were analyzed. RESULTS The mean preoperative and postoperative body mass index (BMI) was 44.1 ± 6.9 and 33.4 ± 6.8 kg/m(2), respectively (p < 0.001). The mean excessive body weight loss after a median follow-up of 11.9 months was 55.7 % ± 24.9 %. Three bleedings, two staple line leakages, and a deep wound infection required conversion to laparotomy (n = 1), reoperation (n = 4), or endoscopic stent implantation (n = 2). Resolution of diabetes and dyslipidemia was seen in 85 and 50 % of patients, respectively. Blood test results of HbA1c, cholesterols, triglycerides, and leptin showed significant postoperative improvement. CONCLUSIONS Laparoscopic SG represents a feasible bariatric procedure with good short-term weight loss, low morbidity rate, and efficient resolution of diabetes and dyslipidemia, especially in patients with lower BMI. The significant decrease of leptin necessitates further studies to understand the ambiguous role of leptin in bariatric surgery.

Abstract
Laparoscopic sleeve gastrectomy (LSG) has become a common surgical procedure, yet there is no consensus on what bougie size is best for LSG. We reviewed the literature and assessed the relationship between the size of bougie used and the incidence of leak as well as weight loss parameters. We wanted to determine if there is an ideal bougie size for LSG. A search of the medical literature was undertaken. We limited the search to articles published in the last 5 years written in English and investigating humans. We analyzed 32 publications comprising 4,999 patients. We determined the frequency of staple line leaks as well as weight loss parameters in relation to bougie size. This study was exempt from our institutional review board. The use of bougies of 40 French (F) and larger was associated with a leak rate of 0.92% as opposed to 2.67% for smaller bougies (p < 0.05). Weight loss in percent of extra weight loss (%EWL) was 69.2% when a bougie of 40 F and larger was used, as opposed to 60.7% of EWL when smaller bougies were used (p = 0.29). LSG is becoming an important and common procedure. Larger sizing bougies are associated with a significant decrease in incidence of leak with no change in weight loss. Further studies are needed before an unequivocal decision on the optimal bougie size is made. A recommendation to use the smallest bougie possible should be avoided because the risks may outweigh the benefits.

Abstract
BACKGROUND AND OBJECTIVES Laparoscopic sleeve gastrectomy is gaining popularity as a bariatric procedure, with outcomes similar to gastric band and gastric bypass. Staple-line disruption is a significant source of morbidity and death. We aim to evaluate the effect of staple-line reinforcement on the gastric leak rate, morbidity, and mortality rate. METHODS A systematic review was performed using title key words "sleeve gastrectomy," and articles were reviewed for description of operative technique and postoperative outcomes including staple-line leak. Rates of leak, bleeding, surgical-site infection, reintervention, readmission, and mortality were analyzed. We calculated pooled event rates and 95% confidence intervals using fixed-effects modeling to determine differences between the reinforcement group (group A) and non-reinforcement group (group B). RESULTS We identified 390 articles, and 30 met the inclusion criteria. Group A had 3293 patients, and group B had 1588 patients. After heterogeneity calculations, 9 variables met the criteria to be analyzed. The leak rate was 3.9% (95% confidence interval, 2.9%-5.5%) in group A and 3.2% (95% confidence interval, 2.8%-4.1%) in group B. The mortality rate was 0.8% (95% confidence interval, 0.4%-1.5%) in group A and 0.7% (95% confidence interval, 0.4%-1.1%) in group B. Our results also showed no statistical difference for any of our other 7 outcome variables. CONCLUSION Our study shows a lack of statistical difference in leak rate, overall morbidity, or mortality rate in laparoscopic sleeve gastrectomy with or without staple-line reinforcement. Because of study limitations, we propose that prospective trials are needed to determine the effect of staple-line reinforcement on leak rates.

Abstract
OBJECTIVE The study compared laparoscopic sleeve gastrectomy (LSG) staple-line leak rates of 4 prevalent surgical options: no reinforcement, oversewing, nonabsorbable bovine pericardial strips (BPS), and absorbable polymer membrane (APM). BACKGROUND LSG is a multipurpose bariatric/metabolic procedure with effectiveness proven through the intermediate term. Staple-line leak is a severe complication of LSG for which no definitive method of prevention has been identified. METHODS The systematic review study design was employed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement screening guidelines. Inclusion criteria centered on variables potentially relevant to LSG leak: leak rate, age, gender, calibrating bougie size, distance between pylorus and gastric transection line, overall complication rate, and mortality. Analysis of variance models were used to explore differences in select demographic and surgical technique variables characterizing each reinforcement group. An omnibus χ(2) test followed by independent Fisher's exact tests were used to compare leak rates. RESULTS There were 659 articles identified; 41 duplicates removed. Of 618 remaining articles, 324 did not meet inclusion criteria. Of the 294 remaining articles, 206 were eliminated (kin studies, those not reporting staple-line or leak incidence, those reporting discontinued products). There were 88 papers included in the analysis. Statistically significant differences were found between groups across demographic and surgical variables studied (p<0.001). There were 191 leaks in 8,920 patients; overall leak rate 2.1%. Leak rates ranged from 1.09% (APM) to 3.3% (BPS); APM leak rate was significantly lower than other groups (p< 0.05). CONCLUSION Systematic review of 88 included studies representing 8,920 patients found that the leak rate in LSG was significantly lower using APM staple-line reinforcement than oversewing, BPS reinforcement, or no reinforcement.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy is increasingly being acknowledged as an effective independent bariatric procedure for obese persons with type 2 diabetes. Data on laparoscopic sleeve gastrectomy from India on this group of patients are limited. This study presents 12-month follow-up data of laparoscopic sleeve gastrectomy on obese Indian patients with type 2 diabetes. SUBJECTS AND METHODS In total, 43 obese patients with type 2 diabetes who received sleeve gastrectomy surgery in the Department of Bariatric Surgery, Medanta the Medicity, Gurgaon, India, were evaluated prospectively for a period of 1 year. RESULTS Seven patients missed follow-up visits, and one patient died, leaving 35 patients who were analyzed. The mean glycated hemoglobin (HbA1c) levels at baseline and 12 months after surgery were 7.94±1.9% and 5.80±0.7%, respectively (P<0.001). Of these, 77.14% reached the primary end point of HbA1c level ≤6% without medication. HbA1c level at target (i.e., <7%) occurred in 91.4%. The mean body weight decreased from 122.08±23.32 kg to 83.43±15.12 kg at 12 months (P<0.001). The percentage of weight loss and percentage of excess weight loss at 12 months were 31.14±7.8% and 61.52±15%, respectively. Antidiabetes medication use decreased from 88.57% to 11.4%. CONCLUSIONS Laparoscopic sleeve surgery is a safe and effective treatment option among the obese Indian type 2 diabetes population with significant remission rates. Follow-up studies are necessary to assess the long-term durability of these results.

Abstract
After establishing a foothold in the West, the pandemic of obesity now threatens to spin out of control in the developing nations of Asia and the Indian subcontinent. Like many of its neighbors, Pakistan has witnessed an unprecedented growth in the number of overweight and obese individuals in its population, and obesity is proving to be an issue of considerable public health concern. Conventional medical therapies for obesity and related complications have proven to be less than effective, especially in the population of the southeast, which appears to be inherently predisposed to developing obesity-related complications. Bariatric surgery is fast emerging as a definitive therapeutic alternative for obesity and has proven to be highly successful and cost-effective at producing remission of complications of the same. In this article, we expound the need for introducing and incorporating bariatric surgery as part of the therapeutic protocols for obese individuals of South Asian descent suffering from the chronic and debilitating complications of obesity.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been gaining acceptance because it has shown good short- and mid-term results as a single procedure for morbid obesity. The aim of this study was to compare short- and mid-term results between laparoscopic Roux-en-Y gastric bypass (LRYGB) and LSG. METHODS Observational retrospective study from a prospective database of patients undergoing LRYGB and LSG between 2004 and 2011, where 249 patients (mean age 44.7 years) were included. Patients were followed at 1, 3, 6, 12, and 18 months, and annually thereafter. Short- and mid-term weight loss, comorbidity improvement or resolution, postoperative complications, re-interventions, and mortality were evaluated. RESULTS One hundred thirty-five LRYGB and 114 LSG were included. Significant statistical differences between LRYGB and LSG were found in operative time (153 vs. 93 min. p < 0.001), minor postoperative complications (21.5 % vs. 4.4 %, p = 0.005), blood transfusions (8.8 % vs. 1.7 %, p = 0.015), and length of hospital stay (4 vs. 3 days, p < 0.001). There were no differences regarding major complications and re-interventions. There was no surgery-related mortality. The percentage of excess weight loss up to 4 years was similar in both groups (66 ± 13.7 vs. 65 ± 14.9 %). Both techniques showed similar results in comorbidities improvement or resolution at 1 year. CONCLUSIONS There is a similar short- and mid-term weight loss and 1-year comorbidity improvement or resolution between LRYGB and LSG, although minor complication rate is higher for LRYGB. Results of LSG as a single procedure need to be confirmed after a long-term follow-up.

Abstract
BACKGROUND Weight loss and reduction in comorbidities can be achieved by longitudinal sleeve gastrectomy (LSG). Existing evidence suggests that LSG resolves or improves hyperlipidemia in morbidly obese patients. The aim of this study was to systematically review the effect of LSG on hyperlipidemia. METHODS A systematic literature search was conducted from English-language studies published from 2000 to 2012 for the following databases: MEDLINE, EMBASE, CINAHL, PubMed, Clinical evidence, Scopus, Dara, Web of Sciences, TRIP, Health Technology Database, Cochrane library, and PsycINFO. RESULTS A total of 4,211 articles were identified in the initial search, and 4,185 articles were excluded based on the exclusion criteria. Twenty-six studies met the inclusion criteria for this systematic review, involving 3,591 patients. The mean preoperative body mass index (BMI) was 48 ± 7.0 kg/m(2) (range 37.2-65.3). The mean postoperative BMI was 35 ± 5.9 kg/m(2) (range 26.3-49). The mean percentage of excess weight loss (EWL) was 63.1% (range 37.7-84.5), with a mean followup of 19.1 months (range 6-60). The mean levels of pre and post operative cholesterol were 194.4 ± 12.3 mg/dL (range 178-213) and 181 ± 16.3 mg/dL (range 158-200), respectively. CONCLUSION Most patients with hyperlipidemia showed improvement or resolution of lipid profiles after LSG. Based on this systematic review, LSG has a significant effect on hyperlipidemia in the form of resolution or improvement in the majority of patients.

Abstract
Laparoscopic sleeve gastrectomy (LSG) is a relatively new bariatric surgical procedure associated with an acceptable weight loss and a relatively low morbidity. There is existing evidence suggesting bariatric surgery resolves or improves hypertension. The purpose of this study is to systematically review the effect of LSG on hypertension. An electronic search method was primarily used for identification of the studies. We performed a comprehensive search of all electronic databases (MEDLINE, PubMed, Embase, Scopus, Dare, Clinical Evidence, BIOSIS, Previews, TRIP, Web of Science, Health Technology Database, Conference abstracts, clinical trials, and the Cochrane Library database) using broad search terms. All human studies from August 2000 to September 2011 were included. After an initial screening, a total of 326 studies were identified. After assessment of these studies based on our exclusion criteria, 222 studies were considered for the abstract review. A total of 33 studies were identified after a careful screening, involving a total of 3,997 patients. The mean pre-operative body mass index (BMI) was 49.1 ± 7.5 kg/m(2) (range 37-68). The average follow-up time was 16.9 ± 9.8 months (range 12-48). The mean post-operative BMI was 36 ± 7.0 kg/m(2) (range 25.6-54). LSG resulted in resolution of hypertension in 58% of patients. On average, 75% of patients experienced resolution or improvement of their hypertension. Based on our systematic review, LSG has a significant effect on hypertension, inducing resolution or improvement in the majority of cases. Therefore, LSG remains a viable surgical option in obese patients with hypertension.

Abstract
BACKGROUND The clinical significance of sleeve gastrectomy (SG) as a primary bariatric intervention is still under debate. This article aims to systematically analyze excessive weight loss (EWL) in patients after SG. METHODS A systematic literature search on SG from the period January 2003 to December 2010 was performed. Data described from systematic reviews dealing with gastric bypass procedures was used as comparator. RESULTS The final study included 123 papers describing 12,129 patients. Most of the papers describe EWL at 12 months (43.9% of all papers). For SG, the maximum EWL occurred 24 and 36 months postoperatively with a mean EWL of 64.3% (minimum 46.1%, maximum 75.0%) and 66.0% (minimum 60.0%, maximum 77.5%), respectively. At 12 months, the mean EWL in patients receiving SG was significantly lower when compared to patients who underwent gastric bypass (SG 56.1%, gastric bypass 68.3%; p < 0.01, two-sided Wilcoxon test). Although patients with gastric bypass still had higher EWL rates at 24 months compared to patients after SG, these differences were not significant (SG 61.3%, gastric bypass 69.6%; p = 0.09, two-sided Wilcoxon rank-sum test). Reoperations after SG are necessary in 6.8% (range 0.7-25%) of cases with patients receiving SG as a stand alone procedure and in 9.6-28.5% of cases with patients undergoing SG as a planned first stage procedure. CONCLUSIONS SG is an effective bariatric procedure with a lasting effect on EWL. Compared with gastric bypasses, there is no difference in EWL at the time point of 24 months.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has become very popular nowadays among bariatric surgeons because of its surgical simplicity and good postoperative results. We present our experience on LSG as a single stage primary bariatric procedure for morbid obesity and its 1-3-year follow-up results. METHODS Between March 2008 and March 2011, a total of 110 patients underwent laparoscopic sleeve gastrectomy. Two patients were excluded from the study and thus the prospectively maintained data of 108 patients were retrospectively reviewed and outcomes were recorded. RESULTS The mean patient age was 39.3 ± 11.1 years, mean body mass index was 44.5 ± 6.8, mean excess body weight was 54.1 ± 16.3 kg, and the mean American Society of Anesthesiologists score was 3.1 ± 0.57. The mean operative time for the LSG procedure was 64.8 ± 10.6 min. The minimum follow-up duration was 6 months and maximum of 36 months. The mean postoperative percent excess body weight loss achieved was 67.5 ± 13.0 at 1 year, 71.1 ± 13.8 at 2 years, and 66.09 ± 14.3 at 3 years. At the end of 3 years, there was 83.3% resolution in diabetes, 85.7% resolution in hypertension, and 85.71% resolution in dyslipidemia. There were no reports of postoperative hemorrhage, gastric leak, deep venous thrombosis, pulmonary embolism, delayed gastric tube stricture, and operative mortality. CONCLUSIONS LSG is a safe and effective bariatric procedure with low perioperative complications. Before it is considered as a single stage primary procedure, a long-term prospective comparative study with other bariatric procedures is required.

Abstract
Sleeve gastrectomy was conceived in 1988 both as a first step to the duodenal switch procedure and as an extension of anti-reflux surgery where patients lost significant weight. It is now a stand-alone laparoscopic bariatric procedure worldwide with two international consensus summits identifying it as a safe and feasible restrictive and appetite-suppressing procedure. In our centre, it is a key component in the surgical armamentarium and used as a first-line and revisional procedure for morbid obesity. The procedure is performed using standard five port technique. One year results are reviewed for its feasibility in our Asian patients. Twenty of 48 laparoscopic sleeve gastrectomies have a 1-year follow-up with four of them a revisional procedure for bands with complications. There were 11 males and 9 females (average age 43.6) and a representation of all four major ethnic groups. Average weight and BMI improved from 116.3 to 90.2 kg and 42.5 to 33.1 kg m(-2) after 1 year, respectively. Average weight loss was 26.1 kg and excess weight loss (in percent) was 49.6%. There was an improvement in diabetes mellitus, hypertension, obstructive sleep apnoea and asthma and three complications including two leaks and a gastro-oesophageal spasm/stricture. Laparoscopic sleeve gastrectomy is safe and feasible as first-line surgery for morbid obesity and revisional procedures for band-related complications in the short term. Further studies are required to elucidate the exact mechanisms of weight loss in the sleeve gastrectomy to answer the appropriateness of the variations in the technique and long-term weight loss and morbidity.

Abstract
INTRODUCTION Sleeve gastrectomy has become a popular stand-alone bariatric procedure with comparable weight loss and resolution of comorbidities to that of laparoscopic gastric bypass. The simplicity of the procedure and the decreased long-term risk profile make this surgery more appealing. Nonetheless, the ever present risk of a staple-line leak is still of great concern and needs further investigation. METHODS An electronic literature search of MEDLINE database plus manual reference checks of articles published on laparoscopic sleeve gastrectomy for morbid obesity and its complications was completed. Keywords used in the search were "sleeve gastrectomy" OR "gastric sleeve" AND "leak." We analyzed 29 publications, including 4,888 patients. We analyzed the frequency of leak after sleeve gastrectomy and its associated risks of causation. RESULTS The risk of leak after sleeve gastrectomy in all comers was 2.4%. This risk was 2.9% in the super-obese [body mass index (BMI) > 50 kg/m(2)] and 2.2% for BMI < 50 kg/m(2). Staple height and use of buttressing material did not affect leak rate. The use of a size 40-Fr or greater bougie was associated with a leak rate of 0.6% compared with those who used smaller sizes whose leak rate was 2.8%. Leaks were found at the proximal third of the stomach in 89% of cases. Most leaks were diagnosed after discharge. Endoscopic management is a viable option for leaks and was documented in 11% of cases as successful. CONCLUSIONS Sleeve gastrectomy has become an important surgical option for the treatment of the ever growing morbidly obese population. The risk of leak is low at 2.4%. Attention to detail specifically at the esophagogastric junction cannot be stressed enough. Careful patient selection (BMI < 50 kg/m(2)) and adopting the use of a 40-Fr or larger bougie may decrease the risk of leak. Vigilant follow-up during the first 30 days is critical to avoid catastrophe, because most leaks will happen after patient discharge.

Abstract
Published data show that bariatric surgery not only leads to significant and sustained weight loss but also resolves or improves multiple comorbidities associated with morbid obesity. Evidence suggests that the earlier the intervention the better the resolution of comorbidities. Patients with metabolic syndrome and comorbidities associated with morbid obesity should be promptly referred for consideration for bariatric surgery earlier in the disease process.

Abstract
Morbid obesity is associated with increased morbidity and represents a major healthcare problem with increasing incidence worldwide. Bariatric surgery is considered an effective option for the management of morbid obesity. We searched MEDLINE, Current Contents and the Cochrane Library for papers published on bariatric surgery in English from 1 January 1990 to 20 July 2010. We also manually checked the references of retrieved articles for any pertinent material. Bariatric surgery results in resolution of major comorbidities including type 2 diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome, non-alcoholic fatty liver disease, nephropathy, left ventricular hypertrophy and obstructive sleep apnea in the majority of morbidly obese patients. Through these effects and possibly other independent mechanisms bariatric surgery appears to reduce cardiovascular morbidity and mortality. Laparoscopic Roux-en-Y gastric bypass (LRYGB) appears to be more effective than laparoscopic adjustable gastric banding (LAGB) in terms of weight loss and resolution of comorbidities. Operation-associated mortality rates after bariatric surgery are low and LAGB is safer than LRYGB. In morbidly obese patients bariatric surgery is safe and appears to reduce cardiovascular morbidity and mortality.
