Hepatic resection for primary and metastatic tumors

Abstract

Thirty-four hepatic resections were performed on 33 patients. These included 4 trisegmentectomies, 14 lobectomies, 7 segmentectomies, and 9 wedge resections. Twenty patients had metastatic colorectal cancer, 4 had a primary liver tumor, 2 had giant cavernous hemangioma, 1 had metastatic leiomyosarcoma, 5 had various benign lesions including focal nodular hyperplasia, and 1 patient had resection for trauma. Operative morbidity included four subphrenic abscesses, one bile leak, one bile duct injury, one case of cholestasis, and one case of phlebitis. There were no operative deaths. The median survival of the patients with metastatic colorectal cancer was 40 months, and the 5-year actuarial survival rate was 35 percent. Survival rates were not significantly different between patients with a solitary metastasis and those with multiple lesions and was not influenced by size of the metastases. However, survival was significantly better in patients whose primary colorectal lesion was Dukes' B as compared with those whose lesion was Dukes' C. The results indicate that liver resection can be performed safely with acceptable morbidity and improved long-term survival.
