Background: Bariatric surgery is a complex procedure not exempt of complications. Aim: To assess mortality and complications of excisional gastric bypass among morbidly obese subjects. Material and methods: Prospective analysis of 684 morbid obese patients (age range 14-70 years, 525 females) subjected to an excisional gastric bypass. Major postoperative complications and mortality were registered. Results: Mean body mass index (BMI) of the subjects was 43.7 kg/m². One hundred sixty two patients had a BMI between 35 and 39.9 kg/m², 419 had a BMI between 40 and 49.9 kg/m² and 103 had a BMI over 50 kg/m². Two patients with a BMI of 52 and 56 kg/m² respectively, died in the postoperative period (0.3%). Thirty six patients had major complications. Anastomotic fistula was the most common complication in 12 patients (1.7%). Fourteen patients required a new operation due to complications. None of these died. The mean operative volume of the surgical team was 124 patients per year. Conclusions: Excisional gastric bypass has a low rate of mortality and complications, if the surgical team operates a large volume of patients
