Successful Laparoscopic Hepaticojejunostomy for Infant Congenital Biliary Dilatation with both Aberrant Right Hepatic Artery and Bile Duct from the Caudate Region
Abstract
A boy with congenital hydronephrosis underwent ultrasonography every month for follow-up. At 4 months of age, ultrasonography incidentally revealed congenital biliary dilatation (5-cm type Ia). We performed laparoscopic extrahepatic bile duct resection and hepaticojejunostomy. After dissecting the dilated common bile duct (CBD), we found that the arcading-like shaped right hepatic artery (RHA) coursed in front of the CBD. Additionally, a tiny duct was identified below the main hepatic duct. At first, we thought it was a lymphatic vessel and dissected it from the main hepatic duct. However, bile flow out was recognized after dissecting the tiny duct. Finally, we confirmed it as an aberrant bile duct from the caudate region. We anastomosed the bile duct from the caudate region and main hepatic duct in a double-barrel fashion and performed hepaticojejunostomy below the RHA. The postoperative course was uneventful. Ultrasonography showed no intrahepatic ductal dilatation including the caudate lobe.

Written informed consent was obtained from the parent of the patient for the publication of this article and accompanying images.
Note
An aberrant hepatic artery and an aberrant hepatic duct are sometimes recognized during hepatobliliary surgery, especially in congenital biliary dilatation. Pediatric surgeons have to do the appropriate decision of operative procedure and perform secure definitive surgery for unexpected anomalies in congenital biliary dilatation.
