Abstract
Sixty-two patients underwent hepatic resection for isolated colorectal metastases from 1963 to 1988. The numbers of hepatic resections were: lobectomy, 24 (39 percent); wedge resection, 23 (37 percent); and segmentectomy, 15 (24 percent). The median number of intraoperative blood transfusions was 3 0 units (range, 0-16 units). The median number of days in the hospital following hepatic resection was 13 (range, 4-51 days). There were 19 patients (30 percent), who developed a total of 23 complications. Surgery was required for complications in nine patients. Surgical mortality occurred in 5 of 62 (8 percent) patients. The estimated median survival in 56 patients with one to three metastases was 26 months, with a 28 percent estimated 5-year survival. The median size of the metastases was 4.0 cm (range, 0.7-13 cm). The estimated median survival in 27 patients with metastases less than 4 cm in diameter was 26 months, with a 24 percent estimated 5-year survival. The estimated median overall survival from the time of hepatic resection was 25 months.
