The incidence of early complications was low. Three (0.5%) patients experienced pulmonary thromboembolism.

Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. The ages of the patients ranged from 18 to 70 years (average = 46), and their body mass indices ranged from 34.6 to 77 kg/m2. Ninety-three (17.2%) patients were male and 445 (82.8%) were female. The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery) were reviewed. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. Nevertheless, the acceptance of bariatric surgery is still questioned. Santo, Marco Aurelio Pajecki, Denis Riccioppo, Daniel Cleva, Roberto Kawamoto, Flavio Cecconello, Ivanīariatric surgery has proven to be the most effective method of treating severe obesity.
