Abstract
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. By puncturing balloons dilated at the occluded site of B3 and the proximal end of the non-occlusive B2, a tract between B3 and B2 was created, and the catheter was finally successfully inserted from B3 into the jejunum through the dilated tract and B2. The gunsight approach is an option for severe biliary strictures when the conventional approach proves impossible.
