Chylous ascites: a rare complication of radical gastrectomy.

Chylous ascites is the accumulation of lymphatic fluid within the peritoneal cavity, due to trauma or obstruction to the lymphatic system. Postoperative chylous ascites is a rare complication of abdominal surgery. This is frequently reported after retroperitoneal dissections, and results in high morbidity and mortality. The treatment options are varied and include total parenteral nutrition (TPN), elemental diet with medium chain triglycerides (MCT), repeated paracentesis and surgical ligation. We report a case of post-operative chylous ascites after D2 distal gastrectomy. Treatment by fasting, TPN followed by fat-free diet resulted in complete resolution of ascites within 3 weeks. To our knowledge this is the first report of such a complication following radical gastrectomy. We review the literature and briefly discuss the management options.
