RÉSUMÉ
Chylous ascites is a rare complication following bariatric surgeries. Little data is available regarding chylous ascites following bariatric surgeries per se or in association with internal hernias. Herein we present two cases of chylous ascites following Roux-En-Y gastric bypass; the first one is a 60-year-old male who was presented to the ER six months after a gastric bypass operation suffering from abdominal pain, CT scan and upper endoscopy were normal, however chylous ascites and internal hernia were found during exploratory laparoscopy. The second case is a 39-year-old female patient who was admitted three years following the gastric bypass operation and diagnosed to have small bowel obstruction due to internal hernia, and during exploratory laparoscopy a chylous ascites was found.
