Abstract
OBJECTIVE
To investigate whether multiple detector CT (MDCT) could detect troublesome aberrant posterior sectoral hepatic duct (PHD) communicating with cystic duct (CD).
METHODS
The most troublesome bile duct anomaly during cholecystectomy is an aberrant PHD communicating with CD. It has been suggested that an unenhanced small duct between Rouviere's sulcus and CD on MDCT could be coincident to an aberrant PHD communicating with CD. A total of 224 patients who underwent laparotomy with complete lymph node dissection in the hepatoduodenal ligament for hepatobiliary or pancreatic tumour were enrolled. Retrospective review of preoperative MDCT images and surgical records was performed.
RESULTS
Preoperative MDCT detected 8 (3.6%) unenhanced ducts between Rouviere's sulcus and CD. Surgical records identified 7 (3.1%) cases of aberrant PHD communicating with CD, and all 7 cases showed an unenhanced duct between Rouviere's sulcus and CD on preoperative MDCT imaging. Among the 7 patients, 5 (71%) were without bile duct dilatation.
CONCLUSION
MDCT could detect troublesome aberrant PHD communicating with CD, regardless of the presence or absence of bile duct dilatation. Advances in knowledge: MDCT could detect most troublesome PHD communicating with CD, regardless of the presence or absence of bile duct dilatation.
