BACKGROUND: Peroral cholangioscopic lithotomy is an effective treatment for extrahepatic bile duct stones. However, an evaluation of the usefulness and long-term results of peroral cholangioscopic lithotomy for hepatolithiasis has not been reported. The aim of this study was to evaluate the usefulness and long-term results of peroral cholangioscopic lithotomy for hepatolithiasis.
METHODS: From August 1987 to July 1998, 36 consecutive patients underwent peroral cholangioscopic lithotomy for hepatolithiasis; 34 were followed for a mean of 93 months (range, 14 to 164 months).
RESULTS: The rate of complete stone removal was 64%; the morbidity rate was 2.8%. The recurrence rate for patients in whom stones were completely removed was 21.7%. Two patients (5.9%) had cholangiocarcinoma develop during follow-up.
CONCLUSION: Although incomplete stone removal and recurrence are common, peroral cholangioscopic lithotomy is a sufficiently safe and effective method for the treatmentof hepatolithiasis.
