Management of postsurgical leaks in the bariatric patient

Postsurgical leaks after bariatric procedures are a significant cause of morbidity and mortality. They usually arise from anastomotic and staple line failures that are attributed to surgical technique, ischemia, and patient comorbid conditions. Timely diagnosis from subtle clinical clues is the key to appropriate management. Traditional treatment consists of adequate control of the intra-abdominal infection via surgical or percutaneous drainage maneuvers, antibiotics, and nutrition support via parenteral or feeding tube routes. Recently, endoscopically placed covered esophageal stents have been used to exclude the leak site, allowing oral nutrition and speeding healing.
