Type of weight loss surgery matters for people with severe obesity

(Reuters Health) - People who have weight-loss surgery for extreme obesity may lose more weight with an older operation known as Roux-en-Y gastric bypass than with a newer sleeve gastrectomy procedure, a small U.S. study suggests.

AbstractIntroductionBone mineral density (BMD) declines in the initial years after bariatric surgery, but long-term skeletal effects are unclear and comparisons between sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are rare.Design and MethodsAn observational longitudinal study of obese patients undergoing SG or RYGB was performed. Whole-body (WB) BMD, along with BMD of the total hip (TH), femoral neck (FN), and lumbar spine (LS), was measured by dual-energy X-ray absorptiometry (DXA) before surgery and yearly thereafter for 4  years. Calciotropic hormones were also measured.ResultsForty-seven patients un...

ConclusionsThis is the first report of cognitive improvements following VSG and the first direct comparison of cognitive improvements following RYGB and VSG. Short-term improvements in specific domains of cognitive function are observed at the beginning of the active weight loss phase following bariatric surgery that persisted to 3  months. The anatomical distinction between the two surgeries and resulting differential metabolic profiles may be responsible for the improvements in attention observed following RYGB but not following VSG.

As recently summarized1, there are only four randomized clinical trials (RCTs) in patients with type 2 diabetes mellitus (T2DM) comparing Roux-en-Y gastric bypass (RYGB) with sleeve gastrectomy (SG) and providing level I evidence up to 5 years after randomization.2-5 None of the individual studies were primarily designed and adequately powered to compare the effects of RYGB with SG on T2DM. However, combined analysis of these RCTs (i.e. meta-analysis) in order to increase the sample size and statistical power (RYGB, n=176 versus SG, n=175) would indicate that either there is no significant long-term difference between RYGB...

ConclusionsForegut pathology is common in bariatric patients with subjective symptoms of GERD. Implementing a comprehensive protocol to objectively assess these patients leads to a significant clinical impact on which procedure these patients ultimately undergo.

This study included patients who underwent primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG). The primary outcome of interest was incisional SSI occurring within 30  days. Surgeries performed in 2015 were used in a derivation cohort and the predictive tool was validated against the 2016 cohort. A forward selection algorithm was used to build a logistic regression model predicting probability of SSI.ResultsA total of 274,187 patients were included with 71.7% being LSG and 28.3% LRYGB. 0.7% of patients had a SSI in which 71.0% had an incisional SSI, and 29.9% had an organ/spa...

Objective: We sought to compare the short and long-term outcomes of MBS in adolescents vs. adults who have undergone a Roux-en-Y gastric bypass (RYGB) or Sleeve gastrectomy (SG).Design: Retrospective cohort study.Setting: Single tertiary care academic referral center.Participants: One hundred fifty adolescent (≤ 21-years) and adult (>21-years) subjects with severe obesity between 15 and 70 years of age who underwent RYGB or SG.Outcomes: Metabolic parameters, weight and height measures were obtained pre-and post-surgery (at 3 and 6 months, and then annually for 4 years).Results: Median pre-surgical body mass index (BM...

We examined the association of hospital length of stay (LOS) by race-ethnicity (Hispanic, non-Hispanic white [NHW], NH black [NHB]) and MBS-procedure among Florida inpatients. DESIGN: Secondary analysis of inpatient records was performed using the 2016 Florida Agency for Health Care Administrative (AHCA) data. Records of Laparoscopic Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Adjustable Gastric Banding (LAGB), and Sleeve Gastrectomy (SG) procedures based on ICD 10th edition code were analyzed. Via logistic regression analysis, the adjusted odds ratio (aOR) of longer LOS (≥2 versus

AbstractBackgroundRevisional gastric bypass (R-RYGB) surgery is utilized for the management of inadequate weight loss or weight regain observed after some cases of bariatric surgeries. Data on the mid-term effectiveness of primary gastric bypass (P-RYGB) compared with R-RYGB (e.g., post sleeve gastrectomy/gastric banding) are controversial.MethodsRetrospective chart review of all patients who received P-RYGB and R-RYGB (January 2011 –June 2015) at our center. One hundred twenty patients who underwent P-RYGB and 34 R-RYGB who completed 18 months follow-up were included. We compared the effectiveness of P-RYGB with R-R...

Bariatric surgery is an effective therapeutic procedure for morbidly obese patients. The two most common interventions are Sleeve Gastrectomy (SG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB).
