Abstract

Background

This study was designed to evaluate the possibility of avoiding small-for-size syndrome (SFSS) in living donor liver transplantation (LDLT) by increasing the donor’s body weight (BW) before liver donation.

Methods

Nineteen participants, including 15 volunteers and 4 liver donors, were enrolled in this study to increase their BW by 1.5–5 kg within 3 months by eating a high-protein and high-carbohydrate diet according to a flexible formula to increase calorie intake.

Results

Fifteen participants, including 12 volunteers and 3 live liver donors, successfully increased their BW by 1.5–5 kg within 3 months (failure rate, 21%). The actual liver weight (LW) gain was more than the expected LW gain using the formula for calculating standard liver volume (2.77- to 8.94-fold; median, 4.49-fold; mean, 4.45-fold, P < 0.005) and using the ratio of liver weight to body weight (1.36- to 4.49-fold; median, 2.01-fold; mean, 2.06-fold, P < 0.005). The enlargement of the livers was symmetrical without significant fatty change. The graft-versus-recipient weight ratio increased 0.17%, 0.07%, and 0.08%, respectively, for the three live liver donors and successful LDLTs were performed.

Conclusions

By having liver donors eat a high-protein, high-carbohydrate diet to increase their BW in a short period of time, the actual LW may increase more than the expected LW gain without fatty change. This method of increasing LW may be used in selected cases of LDLT to avoid SFSS.
