From December 1981 to October 1997, we had performed 1559 cases of intrahepatobiliary tract stones by surgery alone/or with cholangioscopy, of which 332 cases were left intrahepatobiliary tract stones (accounted for 33.9%), 111 right intrahepatobiliary tract stones (accounted for 11.3%) and 545 cases in both sides (54.7%). 324 patients complicated with stricture of biliary tract (32.3%), of which 156 cases (48.2%) were stricture of left intrahepatobiliary tract, 107 cases (33.0%) stricture of right intrahepatobiliary tract, 61 cases (18.8%) stricture of hepatic hilus biliary tract. The operative procedure were: ①hapatic lobe or segment resection, ②high cholangiotomy and palstic repair, ③choledochojejunostomy and ④T-tube or U-tube drainage with removal of stones by cholangioscopy later. The operative procedure should be based on different types of intrahepatobiliary tract stones and patholigical features. The result indicates that cholangioscopy may play an important role in the treatment of intrahepatobiliary tract stones.
