Appendix as a biliary conduit for choledochal cysts in children.

Biliary conduits are constructed in operations for choledochal cysts. A wide variety of options are available for biliary tract reconstruction. We present our experience of treating six children with choledochal cysts by using the appendix as a biliary conduit. After mobilizing the appendix on its vascular pedicle, nonrefluxing, tunneled anastomosis was made with the 2nd part of the duodenum and the appendix. The operative procedure was simple and less time-consuming. Postoperative evaluation was done with the help of HIDA scan and ultrasound examination. Postoperative cholangitis was conspicuously absent in the two years of follow-up. One child has been lost to follow-up. From our preliminary experience, the operation seems simple and satisfying. Though the long-term efficacy still remains to be proven, the appendix should prove durable as a functional conduit.
