RESUMO
CONTEXT: 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. CASE REPORT: 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. CONCLUSION: 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.
