Benefits and complications of the duodenal switch/biliopancreatic diversion compared to the Roux-en-Y gastric bypass.

The duodenal switch/biliopancreatic diversion has not gained widespread acceptance among patients or physicians, says Dr Dorman of the University of Minnesota, Minneapolis – is it because it leads to less impressive outcomes? After performing almost 200 duodenal switch/biliopancreatic diversions between 2005 and 2010, Dorman says this isn't the case: the procedure engenders both superior weight loss and improvement of major comorbidities, while demonstratic similar adverse event and complication rates to gastric bypass.

Barbed Versus Usual Suture for Closure of the Gastrojejunal Anastomosis in Laparoscopic Gastric Bypass: a Comparative Trial.

They found that omental patch repair led to shorter operation time, less blood loss, and a shorter total length of stay. (Full text)

Revisional surgery after failed laparoscopic adjustable gastric banding: a systematic review.

The best way to adapt a failed gastric band is to convert to another bariatric procedure, say Dr Elnahas et al from McMaster University, Canada, after performing a systematic literature review. Patients experience stable weight loss after Roux-en-Y gastric bypass, and converting to laparoscopic biliopancreatic diversion and duodenal switch is promising, although more research is needed in this case.

Clinical Efficacy of Laparoscopic Sleeve Gastrectomy vs Laparoscopic Gastric Bypass in Obese Type 2 Diabetic Patients: a Retrospective Comparison.

Retrospectively examining results from 31 obese T2DM patients, 15 of whom received sleeve gastrectomy while 16 of whom received gastric bypass, Dr Cutolo et al from the S Giovanni Bosco Hospital, Italy, found that the two techniques are similarly effective, both in terms of weight loss and remission of comorbidities.
