title: Primary biliary stones: diagnosis and management.
abstract: To review the results of treatment of primary biliary stones, 96 consecutive patients managed from 1991 to 1996 were studied retrospectively. Acute cholangitis and abdominal pain were the presenting symptoms in 57 patients (59%) and 29 patients (30%), respectively. Fifty-four patients (56%) had a history of biliary surgery. Endoscopic retrograde cholangiopancreatography, ultrasonography, and computed tomography were frequently employed for diagnosis of primary biliary stones and were performed on 84 patients (88%), 90 patients (94%), and 89 patients (93%), respectively. Intrahepatic stones were identified in 91 patients (95%) and biliary strictures in 34 patients (35%). Concomitant cholangiocarcinoma occurred in 15 patients (16%). Hepatic resection was required in 55 patients (57%) for removal of an atrophic liver lobe or a segment related to repeated infection, biliary strictures, liver abscesses, or cholangiocarcinoma. Intraoperative choledochoscopy was routinely performed in all patients to detect, remove, or confirm clearance of biliary stones. A hepaticocutaneous jejunostomy (HCJ) was constructed in 70 patients (73%) to facilitate postoperative choledochoscopic examination or biliary stone extraction. Twenty-two patients (23%) had residual stones and required postoperative choledochoscopic extraction. Complete eradication of residual stones was achieved in all patients. Postoperative morbidity occurred in 28 patients (29%), and there was one hospital death (a patient with cholangiocarcinoma). With a median follow-up of 26 months (range 2-62 months), stones recurred in three patients. In conclusion, the early results of treatment of primary biliary stones were satisfactory owing to a systematic, aggressive approach that consisted of hepatic resection, frequent construction of an HCJ, and postoperative choledochoscopy.
