Long-term results of hepatic resection for hepatolithiasis.
Long-term results of hepatic resection for hepatolithiasis in 34 patients having intrahepatic biliary strictures were studied. The left lateral and the right posterior segmental ducts were commonly and often simultaneously involved. Fourteen patients had multiple segmental involvement. Hepatic resection included left sided resection (n = 27), right sided resection (n = 6), and repeated bilateral resection (n = 1). Seven patients had biliary tumors: 3 cholangiocarcinomas, 2 gall bladder cancers, 1 cystadenocarcinoma, and 1 dysplasia of intrahepatic ducts. Nineteen patients received bilioenteric anastomosis. Retained stones and recurrent stones developed in 3 and 4 patients, respectively. Twenty-six patients had no remaining symptoms; 2 died of operative complication or cholangiocarcinoma; 6 presented symptoms caused by retained stones (n = 2), recurrent stones (n = 2), bile stasis (n = 1), or neuralgia (n = 1). In 4 of the 6 patients, unrelieved posterior duct strictures caused the symptoms. With a mean follow-up period of 4.5 years, 30 patients are symptoms free, and 27 are stone free. In patients with right lobar or bilobar type, intra- and extrahepatic type, and confluence strictures, bilioenteric anastomosis is required. Hepatic resection is a rational treatment for hepatolithiasis, however, meticulous management of biliary tract abnormalities, particularly the posterior duct stricture, is mandatory.
