Background: The use of abdominal drains is a common practice in gastric surgery. Aim: To assess the daily flow of abdominal drains after gastric bypass for morbid obesity. Material and Methods: Prospective study of 359 morbid obese patients subjected to gastric bypass with excision of the distal gastric segment. The daily flow of drainages placed at the right and left side of the anastomosis was measured. Patients with fistulae or other abdominal complications, were excluded. Results: The right drainage had an initial flow of 50 mg/24 h. At the fifth postoperative day the flow was less than 20 ml/24 h and the drain was withdrawn. The left drainage had a higher initial flow of serous or serous-hematic fluid and was maintained for a mean of six postoperative days. Conclusions: The use of abdominal drains after gastric bypass is not associated with complications and allows a daily assessment of the drainage flow
