Non-image diagnosis of bile duct injury during laparoscopic cholecystectomy

<正> Objective: To evaluate the role of simple non-imagetechnique in intraoperative diagnosis of bile duct in-jury (BDI).Methods: BDI was highly suspected at the original la-paroscopic cholecystectomy (LC) when the following 3abnormal findings were noted: the "cystic duct" stump(the common bile duct stump actually) markedly re-tracted down to the duodenum; bile leakage from theporta hepatis; abnormal mucosal patch attached to the"cystic duct" stump of the removed gallbladder. Allcases of suspected BDI were converted to have laparo-tomy. Image techniques such as intraoperative cholan-giography or ultrasonography were not utilized forrecognition of BDI in all 9 patients.Results: BDI in 4 of the 9 patients was suspected ac-cording to 1-3 abnormal intraoperative findings de-scribed above. The four patients were subjected imme-diately to converted laparotomy. Abnormal findingswere not observed or misinterpreted in the other 5misdiagnosed patients.Conclusions: Timely recognizing whether BDI occursshould be considered as a routine procedure ofLC. Negligence of operators to the abnormalities of theoriginal LC, is the main cause of misdiagnosis forBDL. Simple non-image approaches such as close ob-servation of these abnormalities can make timely diag-nosis for most BDIs during the original LC.
