Abstract
The presence of a left-sided gallbladder poses a unique challenge for living related liver donation. Associated anomalies include segment IV atrophy, absence of portal vein bifurcation, and abnormal intrahepatic portal branches to segments II and III. The complex is rare, but is more frequent in Japan. Of 379 living related liver transplants from our institution, the complex has been encountered on four occasions (incidence: 1.1%), and we herein review our experience. Anomalies were identified preoperatively (by computed tomography and ultrasound) in all instances. One donor was turned down because there was no common portal trunk to segment II and III branches. Three donors underwent successful retrieval using a modified technique. There were no complications in the donors or recipients relating to the complex. Thus, living related liver retrieval can be achieved safely in the presence of the left-sided gallbladder/portal anomaly complex, but technical modifications are required.
