Abstract

Cholangioscopic lithotomy (CSL) for hepatolithiasis, a minimally invasive procedure, has a place in complicated or recurrent hepatolithiasis. CSL itself, however, carries inherent risk for recurrence. We analyzed follow-up data after CSL for primary or repeat hepatolithiasis to determine the frequency of recurrence. This retrospective analysis includes 21 patients with hepatolithiasis admitted to the hospital from September 1992 to December 1995 who underwent CSL. Through a percutaneous biliary drainage route, cholangioscopy was inserted to remove calculi with basket forceps or electrohydraulic lithotripter. Stenotic ducts, defined as less than 2 mm in diameter, were dilated with silicone rubber stenting or a balloon dilator. Ten patients were treated for primary hepatolithiasis and 11 for repeat hepatolithiasis. Of the patients with primary hepatolithiasis, one died of complications and the other nine patients underwent complete lithotomy. Among 11 patients who had repeat hepatolithiasis, four had undergone hepatectomy for hepatolithiasis and two previous CSLs; 10 patients (91%) underwent complete lithotomy. During the follow-up, four (40%) of the 10 patients with biliary stenosis at the time of cholangioscopic treatment showe...Continue Reading
