Bypass and sleeve beat AGB for adolescents undergoing surgery

Adolescents undergoing Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) have a greater decline in BMI, compared to those who had laparoscopic adjustable gastric banding (AGB), according to researchers reporting outcomes from the PCORnet Bariatric Study (PBS).  In addition, the authors also reported that the majority of patients maintained weight loss over the five-year follow-up time period, while patients undergoing AGB lost the least weight.

RYGB can reverse fatty liver disease and non-alcoholic steatohepatitis

Roux-en-Y gastric bypass (RYGB) surgery maybe a promising approach to reverse fatty liver disease, and importantly, a potential future therapeutic option for the treatment and reversal of non-alcoholic steatohepatitis (NASH), according to a study by researchers from the Cleveland Clinic, OH.

Rapid improvement in insulin sensitivity post-surgery

Non-diabetic obese patients who have bariatric surgery reported an improvement in  insulin sensitivity (IS), with more pronounced improvements for roux-en-y gastric bypass (RYGB) than for laparoscopic adjustable gastric banding (LAGB), according to a study published in Diabetes Care.

Although bariatric surgery has been shown to have important long-term metabolic effects resulting in enhanced insulin sensitivity and improved glucose tolerance in patients with type 2 diabetes, the contribution of reduced caloric intake to these beneficial effects of surgery remains unclear.

Pre-operative factors and weight loss post-RYGB

A study of patients who underwent gastric bypass surgery found that those who used insulin prior to surgery, had a history of smoking, or took 12 or more medications maintained the greatest weight loss seven to 12 years after the surgery. The study was published by JAMA Surgery.

Ten year outcomes shows durability of RYGB

Roux-en-y gastric bypass is a durable operation for long-term weight loss and treatment of obesity-related comorbid disease, according to researchers from the University of Virginia, Charlottesville, VA. The study, which included 1,087 patients who underwent RYGB procedures over a 20-year study period (1985–2004), reported that excess body mass index significantly improved over time and a significant decrease in obesity-related comorbid disease persisted at ten years of follow-up after RYGB.

Bariatric surgery improves lipid profile in obese patients

Bariatric and metabolic surgery can significantly benefit the lipid profiles of patients a year and more after surgery, according to a report published in The American Journal of Medicine. Researchers from the NYU Langone Medical Center, New York, US, made their conclusions after undertaking a meta-analysis of studies on contemporary bariatric surgery outcomes to describe the effects of Bilio-pancreatic Diversion (BPD), Roux-en-Y Gastric Bypass (RYGBP), Adjustable Gastric Banding, and Sleeve Gastrectomy procedures on serum lipids of obese patients at one year and more after surgery.

Bariatric surgery restores cardiac dysfunction

Bariatric surgery can restore both cardiac and sudomotor autonomic C-fibre dysfunction towards normal in subjects with diabetes, potentially impacting morbidity and mortality, according to a study published in PlosOne.

The advantages of MGB, Diverted-MGB and banded-MGB

The popularity of mini gastric bypass (MGB) has increased in recent years as a simpler, yet safe and effective alternative to roux en y gastric bypass (RYGB). Bariatric News talked to Dr Rui Ribeiro from the Centro Hospitalar de Lisboa Central, Portugal, about the benefits of MGB, Diverted-MGB and banded-MGB…

Alternative method preventing Petersen post-RYGB

Researchers from Brazil have proposed an alternative to closing the Petersen space and thereby preventing internal Petersen hernia in postoperative Roux-en-Y gastric bypass (RYGB) patients.

SILS safe and feasible but controlled trials needed

Laparoscopic single-incision gastric bypass is feasible, safe and reproducible technique used as an access to complex surgeries like gastric bypass in carefully selected patients, according to researchers from Hospital de Clinicas de Porto Alegre, Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil, and the Cleveland Clinic, Bariatric and Metabolic Institute, Cleveland, OH, USA.
