The Value of Choledochoscopy in Exploration of the Common Bile Duct

摘要: Direct visualization of the biliary tree using choledochoscopy has been recommended as a technique to improve accuracy common duct exploration. In several series incidence retained calculi dramatically reduced choledochoscopy, and some authors have reported findings other unsuspected benign malignant lesions well. During an eight-year period 288 patients underwent exploration bile specifically for calculous disease. Operative rigid was performed in 140 this group, with 79 found choledocholithiasis; seven stones occurred group 8.9%. Routine 148 revealed 67 six 9.0%. Though there no difference or without 20 were missed during routine once choledochoscope inserted. addition obvious value identifying removing stones, it also be aid intra-hepatic ducts clarifying atypical anatomy. Other causes obstruction such liver fluke, polyp, strictures, ductal carcinomas identified by use biopsy forceps inserted through choledochoscope. It is that explorations surgical training programs insure residents learn operative choledochoscopy.
