title: Vascular complications in percutaneous transhepatic management of complicated hepatolithiasis with difficult intrahepatic biliary strictures: are they avoidable?
abstract: Little has been reported about hemobilia in the management of complicated residual or recurrent hepatolithiasis with intrahepatic biliary strictures by percutaneous stricture dilation and percutaneous transhepatic cholangioscopic lithotomy. To analyze retrospectively the incidence, possible factors, and management of hemobilia in such patients, a consecutive series of 177 patients was studied from 1983 to 2001: 90 patients in the early, 7.5-year period and 87 patients in the later period, in which some procedures were modified. Minor hemobilia occurred during percutaneous puncture in 6 patients: 4 (4.4%) in the early period and 2 (2.3%) in the later period. Massive hemobilia developed in 14 patients (15.5%) in only the early period, during stricture dilation, lithotripsy, or lithotomy. Immediate arteriography revealed arterial bleeding (7), extravasation (3), pseudoaneurysm (3), or an undetermined source (1). Transcatheter arterial intervention enabled successful hemostasis. Massive hemobilia is a potential serious complication of percutaneous stricture dilation and percutaneous transhepatic cholangioscopic lithotomy but is avoidable.
