The purpose of this study was to investigate and discuss imaging methods and management strategies for congenital choledochal cyst with co-existing intrahepatic dilation and aberrant bile duct as well as other complicated biliary anomalies. In this study we reviewed and analyzed 72 patients with congenital choledochal cyst, ranging in age from 15 days to 12 years old and who were seen at our hospital during the past 12 years, from January 1993 to October 2005. The image manifestation and clinical significance of patients with co- existing intrahepatic biliary dilation and aberrant bile duct were carefully examined during operation via MRCP, cholangiography and choledochoscope. Twenty-two cases (30.1%) presented with intrahepatic bile duct dilation and 12 of these were of the cystic type. That is, the orifice of the dilated intrahepatic tract that converged into the common hepatic duct showed membrane or septum-like stenosis. In 10 cases the dilation tapered off from the porta hepatis to the initiating terminals of the intra-hepatic bile ducts and was not accompanied by stenosis. An aberrant bile duct was observed in 2 of the cases. In 3 cases, the right and left hepatic ducts converged at the choledochal cyst. In conclusion, the imaging methods for intrahepatic bile duct dilation possess important clinical significance. Further, for hepatojejunostomy with radical excision of a choledochal cyst, additional operative procedures for intrahepatic stenosis, possible bile duct malformation and pancreaticobiliary common duct calculi can potentially reduce postoperative complications.

Vascular injuries in laparoscopic cholecystectomy: an underestimated problem.

BACKGROUND: Bile duct injury is a severe complication of laparoscopic cholecystectomy and many reports focus on this topic, especially regarding the long-term success of repair of these injuries. There is some concern, however, as to whether concomitant vascular injuries can jeopardize reconstruction of a bile duct injury following laparoscopic cholecystectomy. METHODS: A review of the current literature on the clinical significance and management of a concomitant vascular injury to the outcome of reconstruction of bile duct injuries following laparoscopic cholecystectomy. Relevant articles were extracted through PubMed, with secondary references obtained from key articles. RESULTS: Although the relevant literature is generally poor, there is a trend of appearance of relatively large series on the topic over the last five years, as opposed to case reports or small series during the previous decade. CONCLUSION: The disruption of the hepatic arterial flow during laparoscopic cholecystectomy is usually well tolerated in an otherwise healthy patient. There is strong evidence that concomitant vascular injuries do not have any impact on mortality after biliary reconstruction. There is also evidence that does increase overall morbidity, but when it comes specifically to long-term anastomotic stricture formation, there is no strong evidence to support a negative impact of a concomitant vascular injury; this is especially true for centers/surgeons with HPB interest.
