A retrospective study on 19 years' choledochofiberscopic treatment for residual stones of biliary tract / 中国微创外科杂志

Objective To summarize our experience in choledochofiberscopic treatment for residual stones of biliary tract. Methods 1105 cases of residual stones of biliary tract diagnosed and treated with choledochofiberscope in the past 19 years were reviewed retrospectively. Results The 1067 patients with residual stones of bile duct were treated with choledochofiberscope for 1483 times altogether. The stones were completely removed in 1035 cases, while the stones were not cleared in other 32 cases. The clearance rate of residual stones was 97.0%(1035/1067). No patient died of choledochofiberscopic treatment. Conclusions Choledochofiberscopic treatment plays an important role in the treatment of residual stones of bile duct, because it not only reduces residual stones of bile duct to avoid repeated operation, but also has some advantages such as excellent safety, minimal invasion, low cost and quicker recovery.

Selective Intrahepatic Cholangiography via Choledochofiberscope and Litholytic Therapy / 昆明医科大学学报

This paper reported twenty-two cases of residual biliary duct stones.Because of biliary duct stenosis of stone impaction,the intrahepatic duct could not show by routine cholangiography through T-tube. We inserted a nylon cathetr lmm in diamenter into the selective biliary duct,and per- formed cholangiography through the catheter.The results were satisfactory in 20 of the 22 pa- tients. In the patients with large stones in the intrahepatic duct,the stone-dissolving liquid was instilled through a catheter which was kept in the selective duct.Finally,the stones fragmentated and were removed out successfully.

Prevention of Complications Caused by Removal of Residual Stones Through Choledochoscope After Operations / 昆明医科大学学报

It is reported here that removal of residual stones and choledochofiberscopy through T-tube fistula were peformed on 512 patients. The removal procdeure followed by complica- tions, including fever (19 cases), hemorrhage (11 cases), fistulation between T-tube fistula and duodenum (6 cases), false passage formed by damage to the fistula (4 cases) and gallstones falling into false passage and being difficult to remove (2 cases) . The compli- cations with exception of the gallstones falling into false passage were adjusted after antibiotic treatment, coagulant drip by inserting a catheter and false passage drainge, respectively. The opening of T-tube fistula did not heal following remval of residual stones after Roux-en-y in two patients whose wounds only healed after suturing the intestinal wall and abdominal wall by reoperation. The causes, prevention and treatment of complications Were discussed in this papar.
