Comparison of four kinds of cholangiographies in the prevention of bile duct injury during laparoscopic cholecystectomy / 中国普通外科杂志

ABSTRACT

Objective The efficacies of four cholangiogrphies were compaired with each other in preventing bile duct injury during the procedure of LC. Methods Four cholangiogrphies were used in LC1. Cold light cholangiography (CLCP); 2. Methylenum coeruleum cholangioguaphy (MCCP); 3. Intraoperative cholangiography (IOCP); 4. Intraoperative endoscopic retrogarde cholangiopancreatography (IERCP). Results The images of CLCP and MCCP were direct and could help operator to identify bile duct structure in LC. The images of IPCP and IERCP were indirect and could not be so helpful. Conclusions CLCP is the only technique that clearly and directly shows the location of the extra hepatic biliary system and may be useful in selected cases with abnormal or uncertain anatomy for the prevention of bile duct injury.
