Chylous ascites associated with radical resection of gastric cancer is a serious clinical condition. Lymph node dissection is indispensable during gastrectomy for gastric cancer. However, postoperative chylous ascites prolongs the hospital stay and re-operation. There are few reports on this subject. Most cases of chylous ascites resolve without treatment, but the condition can result in substantial morbidity. The definition of chylous ascites is ambiguous and varies in the English literature. In this report, we discuss a case of chylous ascites in a 68-year-old man who underwent distal gastrectomy for early gastric cancer at our hospital. He was admitted 8 months after surgery with a main complaint of abdominal swelling. Abdominal puncture helped to diagnose chylous ascites with marked elevation of triglyceride level. The patient received a hypercaloric infusion through a central line, and octreotide acetate, but did not improve. After assessment of lymph outflow by lymph scintigraphy, surgical ligation of the lymph vessels was performed through laparotomy. The volume of milky-white ascites in the abdominal cavity was 3,000 mL. Macroscopically, the fluid was confirmed as flowing from behind the common hepatic artery. Thus, ligation was performed. Chylous ascites has not recurred at 12 months after the re-operation. In summary, a case of chylous ascites after radical gastrectomy for gastric cancer was successfully treated by surgery. We review and discuss the relevant literature.
