Meta-analysis of the effectiveness of laparoscopic adjustable gastric banding versus laparoscopic sleeve gastrectomy for obesity.

ABSTRACT:

Background

Laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) are common weight loss procedures. Our meta-analysis compared these procedures for the treatment of morbid obesity and related diseases.

Methods

We systematically searched the PubMed, Embase, and the Cochrane Library through January 2018. The percentage of excess weight loss (%EWL), improvement or remission of type 2 diabetes mellitus (T2DM) and hypertension were analyzed and compared.

Results

Thirty-three studies with 4109 patients were included. Greater decreases in excess weight were found in patients who received LSG at 6 months (weighted mean difference (WMD) -9.29, 95% confidence interval (CI): -15.19 to -3.40, P = .002), 12 months (WMD -16.67 95% CI: -24.30 to -9.05, P < .0001), 24 months (WMD -19.63, 95% CI: -29.00 to -10.26, P < .0001), and 36 months (WMD -19.28, 95% CI: -27.09 to -11.47, P < .0001) than in patients who received LAGB. However, there were no significant differences in the 3-month outcomes between the 2 groups (WMD -1.61, 95% CI: -9.96 to 6.73, P = .70). T2DM patients after LSG experience more significant improvement or remission of diabetes (odds ratio (OR): 0.22, 95% CI: 0.06-0.87, P = .03). The 2 groups did not significantly differ regarding improvement or remission of hypertension (OR 0.80, 95% CI: 0.46-1.38, P = .42).

Conclusion

LSG is a more effective procedure than LAGB for morbidly obese patients, contributing to a higher %EWL and greater improvement in T2DM.

Project description:Importance:Bariatric surgery is an effective and safe approach for weight loss and short-term improvement in metabolic disorders such as diabetes. However, studies have been limited in most settings by lack of a nonsurgical group, losses to follow-up, missing data, and small sample sizes in clinical trials and observational studies. Objective:To assess the association of 3 common types of bariatric surgery compared with nonsurgical treatment with mortality and other clinical outcomes among obese patients. Design, Setting, and Participants:Retrospective cohort study in a large Israeli integrated health fund covering 54% of Israeli citizens with less than 1% turnover of members annually. Obese adult patients who underwent bariatric surgery between January 1, 2005, and December 31, 2014, were selected and compared with obese nonsurgical patients matched on age, sex, body mass index (BMI), and diabetes, with a final follow-up date of December 31, 2015. A total of 33 540 patients were included in this study. Exposures:Bariatric surgery (laparoscopic banding, Roux-en-Y gastric bypass, or laparoscopic sleeve gastrectomy) or usual care obesity management only (provided by a primary care physician and which may include dietary counseling and behavior modification). Main Outcomes and Measures:The primary outcome, all-cause mortality, matched and adjusted for BMI prior to surgery, age, sex, socioeconomic status, diabetes, hyperlipidemia, hypertension, cardiovascular disease, and smoking. Results:The study population included 8385 patients who underwent bariatric surgery (median age, 46 [IQR, 37-54] years; 5490 [65.5%] women; baseline median BMI, 40.6 [IQR, 38.5-43.7]; laparoscopic banding [n = 3635], gastric bypass [n = 1388], laparoscopic sleeve gastrectomy [n = 3362], and 25 155 nonsurgical matched patients (median age, 46 [IQR, 37-54] years; 16 470 [65.5%] women; baseline median BMI, 40.5 [IQR, 37.0-43.5]). The availability of follow-up data was 100% for all-cause mortality. There were 105 deaths (1.3%) among surgical patients during a median follow-up of 4.3 (IQR, 2.8-6.6) years (including 61 [1.7%] who underwent laparoscopic banding, 18 [1.3%] gastric bypass, and 26 [0.8%] sleeve gastrectomy), and 583 deaths (2.3%) among nonsurgical patients during a median follow-up of 4.0 (IQR, 2.6-6.2) years. The absolute difference was 2.51 (95% CI, 1.86-3.15) fewer deaths/1000 person-years in the surgical vs nonsurgical group. Adjusted hazard ratios (HRs) for mortality among nonsurgical vs surgical patients were 2.02 (95% CI, 1.63-2.52) for the entire study population; by surgical type, HRs were 2.01 (95% CI, 1.50-2.69) for laparoscopic banding, 2.65 (95% CI, 1.55-4.52) for gastric bypass, and 1.60 (95% CI, 1.02-2.51) for laparoscopic sleeve gastrectomy. Conclusions and Relevance:Among obese patients in a large integrated health fund in Israel, bariatric surgery using laparoscopic banding, gastric bypass, or laparoscopic sleeve gastrectomy, compared with usual care nonsurgical obesity management, was associated with lower all-cause mortality over a median follow-up of approximately 4.5 years. The evidence of this association adds to the limited literature describing beneficial outcomes of these 3 types of bariatric surgery compared with usual care obesity management alone.

Project description:To find out effectiveness of revisional laparoscopic sleeve gastrectomy (RLSG) in the patients who had laparoscopic adjustable gastric banding (LAGB) and failed to reduce or regained the weight and effectiveness of sweet abstaining and exercise on postoperative weight loss.This retrospective observational study was conducted at AlMoosa Hospital, Al-Ahsa, Kingdom of Saudi Arabia from December 2011 to November 2016. The patients who failed to reduce, regained the weight or had complications after LAGB, were performed RLSG. They were followed-up at three, six, twelve and twenty-four months intervals. Their weight, percent excess weight loss (%EWL) and body mass index (BMI) at pre-RLSG were compared with post-RLSG. The data was recorded in SPSS 22 and analyzed.Thirty-six patients with male/female ratio of 1:5 underwent RLSG. Twelve (33.3%) were frequent sweet-eaters and twenty-four (66.7%) were not. Fourteen (38.88%) did not have exercise, while twenty-two (61.11%) had daily regular exercise. Their mean pre-RLSG weight, percent excess weight loss (%EWL)and BMI were compared with post-RLSG at the period of three, six, twelve and twenty-four months. Their mean weight reduced from 111.69 kilograms to 96.94, 87.25, 79.56 and 76.11 kilograms respectively. Their mean of the percent excess weight loss (%EWL) reduced to 22.08, 45.75, 59.64 and 66.42 kilograms respectively. Their mean pre-RLSG BMI was 43.50 kg.m-2, which reduced to the mean of 37.79, 34.02, 30.97 and 29.70 respectively. There were no post-operative complications in thirty (83.3%), mild like wound infection and seroma in four (11.1%) and bleeding in two (5.6%) patients. None of the patients had leakage. The patients who kept themselves abstained from sweet consumption and performed regular postoperative exercise had better results. They also had considerable reduction in appetite after RLSG.RLSG is an effective procedure after failed LAGB in terms of weight loss having minimal rate of complications. Moreover, abstaining from sweet consumption and continuing exercise postoperatively has better results.

Project description:ImportanceThere is conflicting evidence about how different bariatric procedures impact health care use.ObjectiveTo compare the impact of laparoscopic adjustable gastric banding (AGB) and laparoscopic Roux-en-Y gastric bypass (RYGB) on health care use and costs.Design, setting, and participantsRetrospective interrupted time series with comparison series study using a national claims data set. The data analysis was initiated in September 2011 and completed in January 2015. We identified bariatric surgery patients aged 18 to 64 years who underwent a first AGB or RYGB between 2005 and 2011. We propensity score matched 4935 AGB to 4935 RYGB patients according to baseline age group, sex, race/ethnicity, socioeconomic variables, comorbidities, year of procedure and baseline costs, emergency department (ED) visits, and hospital days. Median postoperative follow-up time was 2.5 years.Main outcomes and measuresQuarterly and yearly total health care costs, ED visits, hospital days, and prescription drug costs. We used segmented regression to compare pre-to-post changes in level and trend of these measures in the AGB vs the RYGB groups and difference-in-differences analysis to estimate the magnitude of difference by year.ResultsBoth AGB and RYGB were associated with downward trends in costs; however, by year 3, AGB patients had total annual costs that were 16% higher than RYGB patients (P < .001; absolute change: $818; 95% CI, $278 to $1357). In postoperative years 1 and 2, AGB was associated with 27% to 29% fewer ED visits than RYGB (P < .001; absolute changes: -0.6; 95% CI, -0.9 to -0.4 and -0.4; 95% CI, -0.6 to -0.1 visits/person, respectively); however, by year 3, there were no detectable differences. Postoperative annual hospital days were not significantly different between the groups. Although both procedures lowered prescription costs, annual postoperative prescription costs were 17% to 32% higher for AGB patients than RYGB patients (P < .001).Conclusions and relevanceBoth laparoscopic AGB and RYGB were associated with flattened total health care cost trajectories but RYGB patients experienced lower total and prescription costs by 3 years postsurgery. On the other hand, RYGB was associated with increased ED visits in the 2 years after surgery. Clinicians and policymakers should weigh such differences in use and costs when making recommendations or shaping regulatory guidance about these procedures.
