Changes of morphology of cystic duct in bile duct stones secondary to choledocholithiasis / 中华肝胆外科杂志

ABSTRACT

Objective To study the morphological changes of the cyctic duct in bile duct stones secondary to choledocholithiasis.Methods The results of imaging examinations before cholecystectomy and biliary exploration with laparoscopy and cholechodoscopy were respectively analyzed in 108 patients.Meanwhile, the cystic duct morphology, diameter and dilatation during the operation were determined to investigate the features of changes in its morphology.Results Gallstones were confirmed in all of the 108 cases by B-model ultrasonography preoperatively.The gallstone was positive in common bile duct in 76 cases.Common bile duct dilatation was seen in 75 cases and cystic duct dilatation in 21.Common bile duct dilatation was found in 81 cases by MRCP and in 45 by CT.Cystic duct dilatation was found in 36 cases by MRCP and in 19 by CT.Cystic duct variety was found in 9 cases by MRCP.Laparoscopic transcyctic common bile duct exploration(LTCBDE)was performed in those patients with short and wide cystic duct.Conclusion MRCP is the effective method for considering the outlooks of the cystic duct in bile duct stones secondary to choledocholithiasis.
