AWAD F, WILLIAM et al. Long term results of gastric bypass for morbid obesity. Rev Chil Cir [online]. 2007, vol.59, n.6, pp. 443-447. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262007000600010.

Background: Gastric bypass is the standard surgical procedure for morbid obesity. Aim: To evaluate long term results of gastric bypass. Patients and methods: Prospective follow up of 1000 consecutive patients (800 women) subjected to gastric bypass between May 1996 and March 2006. A long term follow up was achieved in 545 patients. Percentage of excess weight loss (% EWL), postoperative complications and evolution of complications associated to obesity were studied. Quality of life was assessed using the BAROS II test . Results: % EWL stabilizes in a range from 72 to 79% and between 12 to 84 months after operation. However, patients followed for 120 months, gain weight and % EWL is reduced to 55%. According to BAROS II, 84% of patients considered results as excellent or good, 14% considered results regular and 2% were dissatisfied with surgical outcome. Complications recorded were thromboembolism in 0.5%, gastrointestinal bleeding in 0.1%, leaks in 2%, necrotizing fasciitis in 0.1%, hemoperitoneum in 0.3% acute pneumonia in 2% and wound infection in 1%. One patient died due to a massive pulmonary embolism. As late complications, hernias appeared in 4%, cholelithiasis in 3%, hair loss in 15%, hypocromic anemia 5%, anastomotic ulcers in 2%, intestinal Obstruction in 1.5%, PTFE ring migration and anastomosis obstruction in 2%. Complications were more common in laparoscopic bypass. In all patients there was a reduction of complications associated to obesity. Conclusions: % EWL is excellent with gastric bypass, but there is weight gain in the long term follow up. Complications associated to obesity are almost always corrected
