Improved graft survival by using three-dimensional printing of intra-abdominal cavity to prevent large-for-size syndrome in liver transplantation.

ABSTRACT:

Backgrounds/aims

While large-for-size syndrome is uncommon in liver transplantation (LT), it can result in fatal outcome. To prevent such fatality, we manufactured 3D-printed intra-abdominal cavity replicas to provide intuitive understanding of the sizes of the graft and the patient's abdomen in patients with small body size between July 2020 and February 2022.

Methods

Clinical outcomes were compared between patients using our 3D model during LT, and patients who underwent LT without 3D model by using 1 : 5 ratio propensity score-matched analysis.

Results

After matching, a total of 20 patients using 3D-printed abdominal cavity model and 100 patients of the control group were included in this study. There were no significant differences in 30-day postoperative complica
