BACKGROUND: The purpose of this investigation is to assess how effective it is to exclude individuals from the liver transplant (LT) using the body mass index (BMI) as a criterion. METHODS AND MATERIALS: A retrospective longitudinal analysis of patients with liver transplant outcomes from January 2002 to May 2020 was conducted using the United Network for Organ Sharing (UNOS) database. RESULTS: A total of 118,486 LT cases included in the study. Based on their BMI, patients were split into three groups: a BMI <
35 kg/m CONCLUSION: The outcomes of LT in patients requiring a LT are not significantly affected using the BMI, considering the advancements in surgical techniques and postoperation improvements, and excluding obese patients based on the BMI alone would be inappropriate.
