A reappraisal of cholangiocarcinoma in patient with hepatolithiasis

Abstract

Background: Hepatolithiasis associated with cholangiocarcinoma is not often encountered. During the past 3 years, an increased incidence of patients with hepatolithiasis associated with cholangiocarcinoma was noted. Data were needed to reliably determine the incidence of this disease.

Methods: Data concerning the relationship between cholangiocarcinoma and hepatolithiasis are presented. The treatment modalities and factors that influence long-term survival are discussed.

Results: The overall incidence of cholangiocarcinoma in association with hepatolithiasis was 5.0% (55 in 1105). Before 1987, 65% of cholangiocarcinoma in association with hepatolithiasis was diagnosed postoperatively. After 1987, the incidence of accurate preoperative diagnosis increased (22.8%), and in most of the other instances (62.8%), the diagnosis was made at laparotomy. Surgical procedures consisted of common bile duct exploration with T-tube drainage (100%) and hepatectomy (38.2%). Mortality for patients who underwent surgery was 5.4%; they died of recurrent cholangitis. The overall median survival time of patients with cholangiocarcinoma in association with hepatolithiasis was 10.4 months; the 1-, 2-, and 4-year cumulative survival rates were 30.0%, 12.7%, and 3.6%, respectively. Patients with hepatectomy or the presence of mucobilia had better survival rates (P < 0.05).

Conclusions: The overall incidence of hepatolithiasis associated with cholangiocarcinoma was 5%. In most patients with cholangiocarcinoma in association with hepatolithiasis, diagnosis can be made preoperatively and at laparotomy. Patients with hepatectomy or presence of mucobilia had better survival rates.
