Use of endoscopy in the treatment of calculus of intrahepatic or extrahepatic duct:A clinical study / 中国微创外科杂志

ABSTRACT

Objective To discuss the application of endoscopic techniques in the treatment of calculus of intrahepatic or extrahepatic duct. Methods Laparoscopy in conjunction with duodenoscopy or cholangioscopy was adopted in 96 cases of calculus of intrahepatic or extrahepatic duct, including 72 cases of cholecystolithiasis complicated by choledocholithiasis, 16 cases of simple choledocholithiasis and 8 cases of left intrahepatic duct calculus complicated by choledocholithiasis. The surgical procedures included laparoscopic cholecystectomy (LC) combined with EST (37 cases), LC combined with cholangioscopic exploration (54 cases), and laparoscopic left hepatic lobectomy combined with cholangioscopic exploration (5 cases). Results Postoperative re-examination revealed no residual calculus in 93 out of 96 patients. Small amounts of biliary leakage occurred in 4 patients and healed spontaneously within a mean time of 10 days. No other severe complications took place. A conversion to open surgery was required in 3 patients, 2 of which were high bile duct stricture and 1 of which were severe portal adhesion. Conclusions Endoscopy in the treatment of calculus of intrahepatic or extrahepatic duct is feasible. Proper application of multiple endoscopic techniques is a safe, effective and minimally invasive means for the treatment of cholelithiasis.
