Comparison of laparoscopic Roux-en-Y gastric bypass with laparoscopic sleeve gastrectomy for morbid obesity or type 2 diabetes mellitus: a meta-analysis of randomized controlled trials

Background

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most widely used bariatric procedures, and laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for treating morbid obesity is becoming more popular. We compared both techniques to evaluate their efficacy in treating morbid obesity or type 2 diabetes mellitus (T2DM).

Methods

We searched the Cochrane Controlled Trials Register databases, Medline, Embase, ISI databases and the Chinese Biomedical Literature Database to identify randomized controlled trials (RCTs) of LRYGB and LSG for morbid obesity or T2DM published in any language. Statistical analyses were carried out using RevMan software.

Results

Five worldwide RCTs with 196 patients in the LRYGB group and 200 in the LSG group were included in our analysis. Compared with patients who had LSG, those who had LRYGB had a higher remission rate of T2MD, lost more weight and had lower low-density lipoprotein, triglycerides, homeostasis model assessment index and insulin levels. There was no difference in the reoperation rate between the groups. However, patients treated with LRYGB had a higher incidence of complication than those treated with LSG.

Conclusion

Our meta-analysis demonstrates that LRYGB is more effective than LSG for the surgical treatment of T2DM and control of metabolic syndrome. However, LSG is safer and has a reduced rate of complications. Further high-quality RCTs with long follow-up periods are needed to provide more reliable evidence.     

Clinical Efficacy of Laparoscopic Sleeve Gastrectomy vs Laparoscopic Gastric Bypass in Obese Type 2 Diabetic Patients: a Retrospective Comparison

Background

Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are performed in patients with obesity and type 2 diabetes mellitus (T2DM). The aim of this study is to evaluate retrospectively the clinical efficacy of RYGB and SG in two groups of obese T2DM patients.

Methods

From the hospital database, we extracted the clinical records of 31 obese T2DM patients, of whom 15 (7 F/8 M) had undergone laparoscopic SG (LSG) and 16 (7 F/9 M) laparoscopic RYGB (LRYGB) in the period 2005?C2008. The groups were comparable for age (range 33?C59?years) and BMI (range 38?C57?kg/m²). LRYGB alimentary limb was 150?cm, and biliopancreatic limb was 150?cm from the Treitz ligament. LSG vertical transection was calibrated on a 40-Fr orogastric bougie. Data were analysed at 6, 12 and 18?C24?months with reference to weight loss and remission of comorbidities.

Results

The reduction in body weight was comparable in the two groups. At 18?C24?months the percent BMI reduction was 29?±?8 and 33?±?11?% in LSG and LRYGB, respectively. Percent excess weight loss was 53?±?16 and 52?±?19?% in LSG and LRYGB, respectively. Thirteen patients in LSG and 14 patients in LRYGB discontinued their hypoglycaemic medications. Five (55?%) patients in LSG and eight (89?%) in LRYGB discontinued antihypertensive drugs. Three out of five patients in LSG and one out of two patients in LRYGB withdrew lipid-lowering agents.

Conclusions

LSG and LRYGB are equally effective in terms of weight loss and remission of obesity-related comorbidities. Controlled long-term comparisons are needed to establish the optimal procedure in relation to patients?? characteristics.     

Variations in Irisin,Bone Mineral Density,Bone Mineral Content,and Body Composition After Laparoscopic Bariatric Procedures in Obese Adults

Introduction: This study was aimed to assess irisin levels in obesity (OB) and T2DM individuals and investigate the dynamic changes of irisin, bone mineral density (BMD), bone mineral content, and body composition in 19 OB patients after laparoscopic bariatric procedures, and also to evaluate the correlation of irisin, with BMD and body composition. Methods: Forty-five OB, 20 T2DM, and 20 healthy adults had been recruited. Levels of irisin were measured in all subjects. Metabolic characteristics were obtained from OB and T2DM patients. Nineteen patients were randomly assigned to be received Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) procedure and to be completed 6-month follow-up. Irisin, BMD, bone mineral content, and body composition were measured at each visit. Results: Significantly higher circulating irisin levels were measured in the OB group compared with T2DM and control groups. FINS, C-P, HOMA-IR, FBCI, HBCI, ALT, AST, and UA levels of OB were significantly higher than those of T2DM patients. While FBG and HbA1c of the OB were significantly lower than T2DM group. There were significant differences among circulating irisin, BMD, and body composition after laparoscopic bariatric surgery. Levels of irisin were decreased after operations including both LRYGB and LSG surgery compared with preoperation. At each time point (1, 3, and 6 months) of postoperation, there was no significant difference in percentage of total weight loss between LSG and LRYGB group. The positive correlation of irisin levels with total BMD, muscle, and fat masses were found during 6-month follow-up after surgery. Conclusions: The levels of irisin were higher in OB patients. There were positive correlations of irisin levels with total BMD, muscle, and fat masses during 6-month follow-up after surgery. Irisin may be involved in the occurrence and development of obese and it is related to BMD and body composition. Both LRYGB and LSG operations could decrease the circulating levels of irisin.     

A Meta-analysis of 2-Year Effect After Surgery: Laparoscopic Roux-en-Y Gastric Bypass Versus Laparoscopic Sleeve Gastrectomy for Morbid Obesity and Diabetes Mellitus

Literature search was performed for bariatric surgery from inception to September 2013, in which the effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) on body mass index (BMI), percentage of excess weight loss (EWL%), and diabetes mellitus (DM) were compared 2 years post-surgery. A total of 9,756 cases of bariatric surgery from 16 studies were analyzed. Patients receiving LRYGB had significantly lower BMI and higher EWL% compared with those receiving LSG (BMI mean difference (MD)?=??1.38, 95 % confidence interval (CI)?=??1.72 to ?1.03; EWL% MD?=?5.06, 95 % CI?=?0.24 to 9.89). Improvement rate of DM was of no difference between the two types of bariatric surgeries (RR?=?1.05, 95 % CI?=?0.90 to 1.23). LRYGB had better long-term effect on body weight, while both LRYGB and LSG showed similar effects on DM.

Laparoscopic Roux-en-Y Gastric Bypass or Laparoscopic Sleeve Gastrectomy as Revisional Procedure after Adjustable Gastric Band—a Systematic Review

The adjustable gastric band (L)AGB gained popularity as a weight loss procedure. However, long-term results are disappointing; many patients need revision to laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG). The purpose of this study was to assess morbidity, mortality, and results of these two revisional procedures. Fifteen LRYGB studies with a total of 588 patients and eight LSG studies with 286 patients were included. The reason for revision was insufficient weight loss or weight regain in 62.2 and 63.9 % in LRYGB and LSG patients. Short-term complications occurred in 8.5 and 15.7 % and long-term complications in 8.9 and 2.5 %. Reoperation was performed in 6.5 and 3.5 %. Revision to LRYGB or LSG after (L)AGB is feasible and relatively safe. Complication rate is higher than in primary procedures.     

Management of gallstone disease prior to and after metabolic surgery: a single-center observational study

BackgroundRapid weight loss after bariatric surgery is a risk factor for gallstone formation. There are different strategies regarding its management in bariatric patients, including prophylactic cholecystectomy (CCE) in all patients, concomitant CCE only in symptomatic patients, or concomitant CCE in all patients with known gallstones. We present the safety and long-term results of the last concept.MethodRetrospective single-center analysis of a prospective database on perioperative and long-term results of patients with laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) over a 15-year period. The minimal follow-up was 24 months. Concomitant CCE was intended for all patients with gallstones detected by preoperative sonography.SettingAcademic teaching hospital in Switzerland.ResultsAfter exclusion of patients with a history of CCE (11.5%), a total of 1174 patients (69.6% LRYGB, 30.4% LSG) were included in the final analysis. Preoperative gallbladder pathology was detected in 21.2% of patients, of whom 98.4%, or 20.9% of the total patients, received a concomitant CCE. The additional procedure prolonged the average operation time by 38 minutes (not significant) and did not increase the complication rate compared with bariatric procedure without CCE (3.7% versus 5.7%, P = .26). No complication was directly linked to the CCE. Postoperative symptomatic gallbladder disease was observed in 9.3% of patients (LRYGB 7.0% versus LSG 2.3%, P = .15), with 19.8% of those patients initially presenting with a complication.ConclusionThe concept of concomitant CCE in primary bariatric patients with gallstones was feasible and safe. Nevertheless, 9.3% of primary gallstone-free patients developed postoperative symptomatic gallbladder disease and required subsequent CCE despite routine ursodeoxycholic acid prophylaxis.

Laparoscopic bariatric surgery improves candidacy in morbidly obese patients awaiting transplantation

BACKGROUND: To evaluate, at a university tertiary referral center, the safety and efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients with end-stage renal disease (ESRD) and laparoscopic sleeve gastrectomy (LSG) in patients with cirrhosis or end-stage lung disease (ESLD); and to determine whether these procedures help patients become better candidates for transplantation. METHODS: A retrospective review was performed of selected patients with end-stage organ failure who were not eligible for transplantation because of morbid obesity who underwent LRYGB or LSG. The prospectively collected data included demographics, operative details, complications, percentage of excess weight loss, postoperative laboratory data, and status of transplant candidacy. RESULTS: Of the 15 patients, 7 with ESRD underwent LRYGB and 6 with cirrhosis and 2 with ESLD underwent LSG. Complications developed in 2 patients (both with cirrhosis); no patient died. The mean follow-up was 12.4 months, and the mean percentage of excess weight loss at > or =9 months was 61% (ESRD), 33% (cirrhosis), and 61.5% (ESLD). Obesity-associated co-morbidities improved or resolved in all patients. Serum albumin and other nutritional parameters at > or =9 months after surgery were similar to the preoperative levels in all 3 groups. At the most recent follow-up visit, 14 (93%) of 15 patients had reached our institution's body mass index limit for transplantation and were awaiting transplantation; 1 patient with ESLD underwent successful lung transplant. CONCLUSION: The results of this pilot study have provided preliminary evidence that LRYGB in patients with ESRD and LSG in patients with cirrhosis or ESLD is safe, well-tolerated, and improves their candidacy for transplantation.
