Abstract

Although intrahepatic cholangioma is a poor prognostic disease, no effective therapy has been established without hepatic resection. We have treated total 52 patients with intrahepatic cholangioma from April 1989 to November 2002. Twenty-nine patients underwent hepatic resection, 5 patients with unresectable intrahepatic cholangioma underwent open MCT, and 18 patients underwent exploratory laparotomy or no operation. One-year and 2-year survival rates in open MCT group were 80% and 26.7%, respectively. These were slightly higher than those of non-curative resection group and no operation group. Local recurrence of treated area was experienced in only one case. We conclude that the open MCT is one of an effective therapeutic method for the patient of unresectable intrahepatic cholangioma as a multimodal therapy combined with chemotherapy and irradiation.
