Intrahepatic cholangiocarcinoma. Results of aggressive surgical management.

OBJECTIVE

To report the results of a deliberately aggressive surgical management in patients with intrahepatic cholangiocarcinoma.

DESIGN

A case series of patients with intrahepatic cholangiocarcinoma.

SETTING

A tertiary care university hospital in a metropolitan area.

PATIENTS

From 1989 to 1993, 19 patients with intrahepatic cholangiocarcinoma underwent laparotomy, with a 74% resectability rate (14 liver resections). In addition, two selected patients with a slow-growing tumor underwent orthotopic liver transplantation after limited recurrence following resection in one case and after exploratory laparotomy in the other.

INTERVENTIONS

The 14 liver resections included six right or left hepatectomies and eight extended right or left hepatectomies. Total vascular exclusion of the liver was used in nine cases (64%) and resection of the biliary confluence with reconstruction was used in six cases (43%).

RESULTS

There was one postoperative death (7%). There were four postoperative biliary fistulas (28%). Overall actuarial 1- and 2-year survival rates were 58% and 32%, respectively. The 1- and 2-year survival rates were 100% after curative resection (no lymph node invasion, clearance margin of < or = 1 cm, and solitary tumor [five cases]) and 48% and 10% after palliative resection. Median survival was 14 months for the whole series and 27 and 9 months following curative and palliative resections, respectively. The two liver transplant recipients are alive and free of disease at 25 and 31 months.

CONCLUSION

These results support aggressive surgical management in patients with intrahepatic cholangiocarcinoma, including complex liver resection procedures and selective use of orthotopic liver transplantation.
