In brief
Study demonstrates that advanced 3D preoperative planning significantly reduces surgical complications when using large-for-size liver grafts (GRWR ≥4%) in pediatric living donor transplantation. Comparison of outcomes before and after implementing 3D printing and simulation modeling shows improved safety for recipients under 10 kg body weight.
Written by the GCMD Library team from the article.
Background
Using "large-for-size" liver graft, graft-to-recipient weight ratio (GRWR) ≥4%, has been debated in pediatric liver transplantation due to possible graft compartment after abdomen closure. Meticulous preoperative evaluation with three-dimensional (3D) techniques may prevent these problems. This study compared the safety of large-for-size grafts in pediatric living donor liver transplantation (PLDLT) during the eras with or without 3D planning.
Methods
We defined the 3D era was after November 2017 due to our first implication of 3D printing for surgical planning and subsequently developing a 3D simulation implanting model. From November 2004 to July 2021, we enrolled 30 PLDLT patients with body weight (BW) < 10 kg and categorized them into conventional group: GRWR ≥4% before the 3D era (n = 9), 3D group: GRWR ≥4% in the 3D era (n = 8), and control group: GRWR
