Delayed primary closure of the abdominal wall after cadaveric and living related donor liver graft transplantation in children: a safe and useful technique

Abstract

Due to the shortage of size-matched liver donors, relatively oversized liver grafts (even after ex situ volume reduction) are frequently used for liver transplantation in children. This was recently observed when livers from large, living related donors were procured for transplantation in very small recipients. Given that abdominal hyperpressure can compromise vascular flow in the new graft, primary closure of the abdomen was delayed by temporary Silastic prosthetic closure in selected cases. The new technique was original in that the skin was closed, avoiding fluid loss and reducing the risk of infections reported with other techniques, and in that reoperation allowed for a delayed, but primary-type, closure (fascia and skin) that resulted in an esthetically correct aspect. Over a period of 7 years, 330 pediatric liver transplantations were performed, and delayed prosthetic closure was achieved successfully and safely in 47 cases. The present report outlines this clinical experience.
