Abstract:Objective:To explore the technique of T-tube replacement after choledochoscopy.
Methods :Choledochoscopy was performed in 256 cases, replacement of T-tube was conducted by direct insertion technique in 85 cases (Group A),and by a wire-guide technique in 171 cases(Group B).
Results:Three cases of T-tube replacement were unsuccessful in group A, in one case of which, the T-tube was misguided into the bowel and the patient recovered after conservative treatment following the withdrawal of T-tube. In group B, all the T-tube replacements were conducted successfully with the wire-guide technique.
Conclusions:Replacement of T-tube is facilitated by the wire-guide technique.
