Indications for major hepatectomy in cirrhotic liver.
In an investigation of the indications for major hepatic resection of the cirrhotic liver, the records of 152 consecutive patients who had undergone a right hepatic resection between April 1985 and January 1991 were reviewed. A comparison of right hepatic lobectomy and right partial hepatectomy of the liver with no cirrhotic changes, revealed that postoperative values of serum glutamic pyruvic transaminase were significantly higher after right partial hepatectomy than after right lobectomy, despite the fact that there were no significant differences with respect to preoperative laboratory data, and there was a greater blood loss and total weight of the resected liver in patients receiving a right lobectomy as compared with those undergoing partial hepatectomy. These results suggest that in order to enable a more favorable recovery from hepatic resection, it is essential to avoid both mechanical damage and ischemic injury to the residual liver during hepatic surgery. A total of 77 patients underwent a partial hepatectomy of a cirrhotic liver, and among these patients, 16 patients had values of the indocyanine green test of less than 20%, as well as a portal pressure of less than 200 mm saline. Compared with these 16 cirrhotic patients and those patients who underwent right lobectomy, there were no significant differences with regard to the pre-operative laboratory data and portal pressure. These results therefore suggest that major hepatic lobectomy could be performed on selected patients with cirrhotic livers.
