Chylous ascites post open cholecystectomy after severe pancreatitis.

Abstract

Chylous ascites a rare complication post cholecystectomy. There are to our knowledge only 3 reported cases in the literature. We describe a case of chylous ascites post open cholecystectomy in a patient with recent severe pancreatitis. We propose a potential relationship between acute biliary pancreatitis and the development of chylous ascites. We present a 37 year old man with a history of severe biliary pancreatitis 10 months prior. He was electively admitted for laparoscopic cholecystectomy. His surgery was converted to open cholecystectomy due to adhesions. A closed, non suction drain was placed intraoperatively draining serosanguinous fluid. Two days post operatively the draining fluid changed to a milky colour fluid with high triglyceride level. Chylous ascites was confirmed clinically with a 24 hour fast. He was treated with total parenteral nutrition. His chylous ascites resolved with conservative management and his drain was removed. We describe the diagnosis and management of chylous ascites post cholecystectomy. We propose the hypothesis to the aetiology of this rare condition, based on ours and one previous case, that a history of recent severe acute pancreatitis poses a risk factor in the development of chylous ascites.
