Liver transplantation for polycystic liver and massive hepatomegaly.

Liver tumor and other benign liver diseases such as polycystic liver disease can cause massive hepatomegaly and may represent an indication for liver transplantation (LT) in some instances. In this setting, LT can be extremely difficult and challenging due to its decreased mobility and access to vascular supply. Benefit from either a right or a left partial liver resection during the transplant procedure has been advocated to safely accomplish the hepatectomy of the native liver. Although we believe that partial hepatectomy adds some risk to intra-operative bleeding, we alternatively advise a different approach. We have a successful experience with LT in 6 massive hepatomegaly patients due to giant liver lesions. All the transplant procedures were performed without intermediate partial liver resection, showing that selective use of veno-venous bypass can play a significant role in the treatment of massive hepatomegaly.
