Weight gain after short- and long-limb gastric bypass in patients followed for longer than 10 years.

Objective: To complete a long-term (>10 years) follow-up of patients undergoing isolated roux-en-Y gastric bypass for severe obesity.

Background: Long-term results of gastric bypass in patients followed for longer than 10 years is not reported in the literature.

Methods: Accurate weights were recorded on 228 of 272 (83.

Surgery decreases long-term mortality, morbidity, and health care use in morbidly obese patients.

Objective: This study tested the hypothesis that weight-reduction (bariatric) surgery reduces long-term mortality in morbidly obese patients.

Background: Obesity is a significant cause of morbidity and mortality. The impact of surgically induced, long-term weight loss on this mortality is unknown.
