Liver resection and intractable postoperative ascites

Abstract

Among 211 patients who, between 1985 and 1990, underwent liver resection in Kyushu University Hospital, uncontrollable ascites occurred in 53 (25%). A univariate analysis revealed that postoperative death with liver failure occurred more frequently in patients with intractable ascites (p < 0.05). Alanine amino transferase levels were significantly higher in patients with intractable ascites (p < 0.05), but serum bilirubin, alkaline phosphatase and serum albumin levels did not differ significantly. Portal pressure (p < 0.05), the operation time (p < 0.01) and blood loss (p < 0.01) were significantly higher in patients with intractable postoperative ascites. A multiple analysis showed a correlation between the operation time, portal hypertension and postoperative intractable ascites. Postoperative histology revealed that a larger number of patients with cirrhosis had intractable ascites (p < 0.05). We conclude that cirrhosis, portal pressure and operating time are the most important factors related to intractable ascites in the case of hepatectomy. Areas of the liver to be resected should be limited in cirrhotic patients with portal hypertension.
