Incidental Chylous Ascites Associated With Internal Hernial After Bariatric Surgery. Case Series

Bariatric surgery is of great importance due to the high incidence of morbid obesity. Techniques such as laparoscopic gastric bypass, laparoscopic tubular gastrectomy, and other bariatric techniques with gastrointestinal anastomosis are used for its treatment. The incidence of internal hernias in the late postoperative period after bariatric surgery ranges from 0.4 to 8.8%. As a consequence, there may be obstruction of the lymphatic vessels. Although chylous ascites is a rare pathology in bariatric surgery, several cases have been reported in the literature. We present two cases of patients who presented as a late complication of an internal hernia associated with chyloperitoneum.
