Metallic clip migration to T-tube sinus tract after laparoscopic choledochotomy

Migration and translocation of metallic clips in the abdominal cavity after laparoscopic bile duct surgery have been reported to occur in the common bile duct (CBD), hepatic duct, duodenum, and even the ovarium, which could cause severe complications. Here we present three cases of metallic clip migration to the T-tube sinus tract after laparoscopic choledochotomy. Metallic clips were discharged from the sinus tract of the T-tube into the drainage bag in two cases. In another case, clips were found to translocate into the sinus tract during choledochoscopic examination for residual stones in CBD.
