- Abstract: Objective To apply radionuclide hepatobiliary dynamic imaging for studying the bile dynamic characteristics in patients with choledochal dilatation and non-dilatation after cholecystectomy. Methods The clinical data of 34 patients receiving hepatobiliary dynamic examination after cholecystectomy in the First People’s Hospital of Shunde, Shunde Hospital of Southern Medical University, were retrospectively analyzed. Among the 34 cases, 22 cases with choledochal dilatation after cholecystectomy were taken as dilatation group, while the other cases without choledochal dilatation after cholecystectomy were taken as non-dilatation group. Moreover, 12 healthy subjects without undergoing cholecystectomy were selected as control group. The postoperative biliary dynamic parameters in 3 groups were recorded by hepatobiliary dynamic imaging, and the bile dynamic index levels in patients with different degrees of choledochal dilatations were compared. Results No significant difference was found in the peak imaging time and half-time of liver among 3 groups (P>0.05). The time to peak choledochal imaging and the half-time of the common bile duct in dilatation group were (43.87±12.46) and (29.32±5.66) min, respectively, significantly longer than those in non-dilatation group and control group, with statistical differences (P<0.05). The duodenum imaging time and the hepatic to duodenal transit time in dilatation group were significantly longer than those in non-dilatation group and control group, with statistical differences (P<0.05). There were significant differences in time to peak choledochal imaging, the half-time of the common bile duct, duodenum imaging time and the hepatic to duodenal transit time among patients with different degrees of choledochal dilatations, with statistical differences (P<0.05). Conclusion The degree of choledochal dilatation after cholecystectomy is closely related to biliary dynamics. Monitoring biliary dynamics is of great help for determining the severity of choledochal dilatation and guiding clinical practice.
