TITLE: Impact of complex bilio-vascular donor anatomy on donor and recipient morbidity in adult LDLT


Primary objective

• This study aims to determine the differences in the incidence of bilio-vascular complications and morbidity in recipients of LDLT receiving grafts from donors with complex bilio-vascular anatomy, compared to those receiving grafts with single artery, portal vein, bile duct.

Secondary objectives

• To determine whether the presence of complex bilio-vascular anatomy has an impact on donor complications, and adds to donor morbidity.

• To determine whether number (of graft artery/PV/ducts), type (according to the classification of bilio-vascular donor anatomy), or type of anastomoses (using loupes vs. microscope for artery and bile duct, plasty with straight extension vs. Y graft in PV, duct to duct vs. Roux for multiple ducts etc.) determine the incidence of complications.

• To determine whether complications have an impact on long term graft and patient outcomes.

STUDY DESIGN: Retrospective

PARTICIPANTS: International multi-center
