Which is better to use “body weight” or “standard liver weight”, for predicting small‐for‐size graft syndrome after living donor liver transplantation?

AIM: Little evidence about whether to apply graft-to-recipient body weight ratio (GRWR) or graft weight to standard liver weight (GW/SLW) for graft selection has been published. The aim of the present study was to clarify the importance of the correct use of GRWR and GW/SLW for selecting graft according to the recipients' physique in living donor liver transplantation (LDLT). METHODS: Data were collected for 694 recipients who underwent LDLT between 1997 and 2020. RESULTS: = 0.002] was the independent risk factor in non-obese recipients. CONCLUSION: Proper use of the formulas for calculating GRWR and GW/SLW in choosing graft according to recipient BMI is important, not only to meet metabolic demand for avoiding SFSS but also to ameliorate donor shortages.
