Anastomotic leaks after laparoscopic gastric bypass.

The gastrojejunostomy may be the most technically challenging step when performing laparoscopic Roux-en-Y gastric bypass. Patients who develop anastomotic leaks have increased morbidity and mortality rates. Difficulty in diagnosis is related to nonspecific systemic symptoms and limitations in most radiological studies. Our aim is to evaluate the incidence, etiology, diagnosis, management, and prevention of anastomotic leaks occurring in patients undergoing laparoscopic Roux-en-Y gastric bypass.
