Repeat liver resection for recurrent colorectal metastases

Sixteen patients underwent 18 repeat liver resections for recurrence of colorectal hepatic metastases that had been previously resected. Only minor liver resection had been undertaken at the first operation; three were palliative. The second operation was major hepatectomy in ten patients, minor resection in five and orthotopic liver transplantation in one. In one patient, lung metastases were resected before the second operation. One repeat hepatectomy was palliative. After partial liver resection, there were no deaths and complications were observed in six of 15 patients. One patient died 2 weeks after liver transplantation. After the second resection, 2-, 3- and 5-year survival rates were 67, 57 and 30 per cent; the mean survival time was 33 (range 8-93) months. Tumour recurrence was observed in 11 of 14 patients 4-32 (mean 13) months after a second curative liver resection; two patients received a third curative operation for recurrent liver metastases. After the second curative hepatectomy, seven patients died from disease after a mean of 36 (range 14-61) months and seven are currently alive at a mean of 33 (range 8-93) months. Four of these patients are free from disease 26-93 months after resection and three are alive with recurrence. Repeat hepatectomy for recurrent colorectal metastases can prolong survival in selected patients and has low operative risk.
