Delayed bile leakage from a remaining part of segment 8 in a posterior section graft after living donor liver transplantation: a common pitfall in harvesting a posterior section graft? A case report.

In Japan and Korea, where availability of deceased donor organs for solid organ transplantation remains rare, living donor liver transplantation (LDLT) using a posterior section graft (PSG; segments VI+VII, according to Couinaud's Nomenclature for liver segmentation) has now been accepted as a standard procedure that balances donor risk and patient benefits for cases in which right hemi-liver donation is too risky, because of marked volume imbalances between right and left hemi-livers. Compared with other types of grafts, however, the procedure requires detailed knowledge concerning hepatic vascular anatomy and meticulous manipulation during donation surgery. We present herein a case of delayed bile leakage from a remaining part of segment 8 in a PSG, which was considered to be a complication peculiar to LDLT using a PSG.
