ABSTRACT

PURPOSE:

Graft reduction can be a patient's graft-saving option to avoid large-for-size (LFS) syndrome. This study aimed to summarize the literature on graft reduction in adult liver transplantation and to demonstrate the technique of H67 graft hepatectomy.

METHODS:

The technique, shown in a didactical video, entails an ex situ posterior sectionectomy under hypothermic perfusion. The right hepatic vein is identified, and the transection line follows the right hepatic fissure. The Glissonean pedicles are ligated during parenchymal transection.

RESULTS:

A narrative review of the literature yielded 7 studies. A total of 15 liver grafts were reduced in adult liver transplantations. Most of the reductions were ex situ (11/15 [73.3%]). Graft reduction entailed an H67 sectionectomy in 10 cases and an H23 sectionectomy in 1 case. In situ reduction included 1 right hepatectomy (H5678), 2 H67 sectionectomies, and 1 H23 left lateral sectionectomy. The duration of the ex situ reduction averaged 56 minutes (median 40.5 minutes; IQR, 33.0-130.0), and the graft weight-to-recipient weight ratio decreased from 3.57% ± 0.40% to 2.70% ± 0.50% after graft reduction. The average cold ischemia time was 390 minutes (IQR, 230-570). There was no liver retransplantation.

CONCLUSION:

Graft reduction in adult liver transplantation may be necessary to avoid LFS syndrome. Ex-situ H67 posterior sectionectomy represents the easiest graft reduction hepatectomy and is able to minimize the occurrence of graft compression while leaving enough functional liver parenchyma.
