A Case of Severe Biliary Anastomotic Stricture after Living Donor Liver Transplantation Successfully Treated Using the Modified Gunsight Technique with Two Balloon Catheters.

Biliary stricture is a serious postoperative complication of liver transplantation. We report the case of a 2-year-old boy with severe biliary anastomotic stricture after left lobe living donor liver transplantation. As cannulation from the occluded B3 into the jejunum was impossible using the conventional technique, a gunsight approach was utilized.
