Long-term weight change and health outcomes for sleeve gastrectomy (SG) and matched Roux-en-Y gastric bypass (RYGB) participants in the Longitudinal Assessment of Bariatric Surgery (LABS) study.

ABSTRACT:

Background

Data from a US multicenter longitudinal study of bariatric surgery were used to compare weight change (primary outcome) and comorbidities (secondary outcome) in patients who underwent sleeve gastrectomy versus Roux-en-Y gastric bypass.

Methods

This study includes participants who underwent sleeve gastrectomy and matched participants who underwent Roux-en-Y gastric bypass from the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study. Adults undergoing initial bariatric surgical procedures between 2006 and 2009 were enrolled. Participants who underwent sleeve gastrectomy were high-risk or superobese and intended to have a second-stage procedure. Mixed models were used to evaluate percent weight change from baseline through 7 years, and diabetes, dyslipidemia, and hypertension prevalence through 5 years.

Results

Fifty-seven of 59 participants who underwent sleeve gastrectomy were matched one to one. Most were female (68%) and white (81%), and had a median age of 49 (37-56) years and median body mass index of 56.4 (35.5-76.8) kg/m² presurgery. Weight loss was significantly less 1 to 7 years after sleeve gastrectomy versus matched Roux-en-Y gastric bypass (eg, year 7 mean weight loss was 23.6% vs 30.4%, respectively; P = .001). For both surgical groups, prevalence of diabetes, low high-density lipoprotein, and hypertension were significantly (P < .05) lower 5 years postsurgery versus baseline.

Conclusion

Higher-risk or super-obese participants after sleeve gastrectomy lost less weight than did matched Roux-en-Y gastric bypass counterparts throughout 7 years. Both groups exhibited improvements in comorbidities from presurgery through 5 years.

Project description:BackgroundPregnancies occurring after bariatric surgery are associated with various perinatal complications. However, there may be differences in the type of perinatal complications occurring after different methods of bariatric surgery. The aim of the current study was to compare adverse perinatal outcomes in pregnant women following Roux-en-Y Gastric Bypass (RYGB) vs. Sleeve Gastrectomy (SG).MethodsA systematic database search was performed in PubMed, Embase, Scopus and CINAHL. Observational studies comparing perinatal outcomes post-bariatric (RYGB and SG) surgery to pregnancies without prior surgery were selected. Outcomes of interest were: maternal body mass index (BMI) at the time of conception, mode of delivery, time from surgery to conception, birth weight, gestational age and intrauterine fetal death. Article selection, risk of bias assessment and data extraction, were performed by two authors. The study protocol was published in its revised form in PROSPERO, registration number: CRD42021234480.ResultsA total of 3201 records were extracted. After duplicates were removed, 3143 records were screened for inclusion. Six studies fitted the selection criteria, of which four studies were RYGB and two SG (1100 post-RYGB vs. 209 post-SG). For the included studies, higher incidence of both SGA (22.9%, 11.9%, 14.2%) and LGA (4.2%, 4.8%, 1.7%) in SG compared to Roux-en-Y (SGA: 8.8%, 7.7%, 11.5%, 8.3% and LGA: 3.4%, 0.7%) were observed. SG had a shorter surgery to conception interval as compared to RYGB. Risk of bias assessment was moderate to serious for the studies included in the review, with bias in selection of participants being the major reason.ConclusionOur systematic review demonstrated no major differences in BMI, mode of delivery, birthweight, gestational age, or rates of intrauterine death between women having undergone RYGB vs. SG. The rate of SGA and LGA births were higher in the SG group, but this group also had a shorter surgery to conception interval. Future studies are indicated to counsel women of reproductive age on the most appropriate type of bariatric surgery that is associated with the best perinatal outcomes.
