Why the study?
Does isolated gastric bypass improve weight loss outcomes compared to biliopancreatic diversion in obese patients?
Does isolated gastric bypass improve weight loss outcomes compared to biliopancreatic diversion in obese patients?
Isolated gastric bypass provides high success rates for weight loss in obese and morbidly obese patients, comparing favorably to biliopancreatic diversion.
May support isolated gastric bypass for durable weight loss in obese patients; leaves open direct comparison to biliopancreatic diversion in randomized trials.
This study of isolated gastric bypass with a 5.5-year follow-up rate of 88.6% revealed a success rate of 93% in obese or morbidly obese patients and 57% in super-obese patients. Isolated gastric bypass compares favorably with biliopancreatic diversion in terms of weight loss, maximum weight loss, weight regain, current body-mass index, and percentage of patients with a body-mass index less than 35 kg/m2.
