Roux-en-Y gastric bypass

More operations or interventions after gastric bypass than sleeve

A study involving tens of thousands of bariatric surgery patients found that RYGB patients were significantly more likely than sleeve gastrectomy (SG) patients to return to hospital in the years following surgery for an operation or intervention. According to the authors, the study is one of the largest bariatric surgery studies ever done and the first study of its size to focus on health problems years after the procedure.

RYGB associated with a higher risk of subsequent interventions

Although Roux-en-Y gastric bypass (RYGB) appears to be slightly more effective than vertical sleeve gastrectomy (VSG) for weight loss and type 2 diabetes remission, it is also associated with a higher risk of subsequent operative and endoscopic interventions, according to a study led by Wake Forest Baptist Health researchers.

Biliopancreatic diversion improves insulin sensitivity vs RYGB

Some studies have demonstrated that biliopancreatic diversion has been better at reducing diabetes compared to Roux-en-Y gastric bypass, because it typically causes greater weight loss. However, small study by researchers at Washington University School of Medicine in St Louis have reported that biliopancreatic diversion appears to be more effective at eliminating diabetes not just because of greater weight loss but because the procedure itself seems to make patients more sensitive to insulin.

Vitamin concentrations and BMI variation after RYGB

Women who had Roux-en-Y Gastric Bypass (RYGB) had higher BMI and vitamin D deficiency, along with hyperparathyroidism after three years, compared to a non-surgical control group, according to researchers from Brazil. The study authors found no association between variables related to body composition and 25(OH)D concentrations, although vitamin concentrations correlated negatively to BMI variation after undergoing surgery.

Weight regain: Post-op adjuvant weight loss medication is effective

Adjuvant weight loss medications after bariatric surgery can stop weight regain and maintain weight loss, according to a study by researchers from the Bariatric and Metabolic Institute, Department of General Surgery, Cleveland Clinic, Cleveland, OH. The study found that more than one third of patients who received adjuvant weight loss medications achieved>5% weight loss and the response was ‘significantly better’ in gastric bypass and gastric banding patients, compared with sleeve gastrectomy patients.

Bariatric surgery associated with reduction in all-cause mortality

Obese, middle-age men and women who had bariatric surgery have half the death rate of those who had traditional medical treatment over a 10-year period, according to a study assessing the long-term risk of bariatric surgery. The study was by Northwestern University Feinberg School of Medicine and the Clalit Research Institute in Israel.

Majority of women and children insufficiently active after RYGB

The majority of both women undergoing Roux-en-Y Gastric Bypass (RYGB) and children are insufficiently active 48 months after maternal RYGB, according to researchers from Sweden. The researchers reported that objectively measured physical activity (PA) in women remains unchanged while appurtenant children decrease time spent in moderate to vigorous PA (MVPA) and increase sedentary time (ST), from three months before through nine and 48 months after maternal RYGB.

12-year follow-up data shows T2DM remission for RYGB

For patients with severe obesity, Roux-en-Y gastric bypass is associated with lasting benefits, according to the 12-year follow-up results of an observational, prospective study published in the New England Journal of Medicine.

Omega-loop GB beats RYGB for weight loss

Omega-loop gastric bypass (OLGB) results in better weight loss (WL) compared to Roux-en-Y gastric bypass (RYGB), according to a retrospective study by researchers from the Medical University of Vienna, the Karl Landsteiner Institute for Obesity and Metabolic Diseases, Vienna and the Special Institute for Preventive Cardiology And Nutrition (SIPCAN), Salzburg, Austria. The study, ‘The Effect of Roux-en-Y vs.

Medication could improve gastric bypass results

New findings about the mechanisms involved - or not involved - in the effects of the most common form of bariatric surgery suggest that combining surgery with a specific type of medication could augment the benefits of the procedure.
