ABSTRACT
Objective To study the value of intraoperative cholangiography(IOCG) in cholecystectomy for gallbladder stone. Methods The IOCG data of 694 cases in the Affiliated Hospital, Yanan University Medical School were retrospectively analysed. Results Among 694 cases with IOCG, 65 had positve findings. Bile duct stone occurred in 44 patients, residnal stone in cyst duct in 7, bile duct injury in 2, and Mirizzi syndrom in 3. Among the 44 cases with bile duct stone, the age of 4.3% cases was 22～50 years old, 10.3% older than 50 years. The incidence of bile duct stone occurring after 50 years old increased with age. The accurate rate of IOCG was 98% in this series. Conclusions IOCG can not only find residual stone, but also find bile duct abnormality and bile duct injury in time, if correct imagic technique is applied.
