Impact of sarcopenic obesity on outcomes in patients undergoing living donor liver transplantation

Sarcopenia is known to be a poor prognostic factor after liver transplantation (LT). However, the significance of obesity in combination with sarcopenia (sarcopenic obesity) remains unclear. This study examined the impact of sarcopenic obesity on outcomes after living donor LT (LDLT). We retrospectively analyzed 277 adult patients who underwent LDLT at our center between January 2008 and June 2016. Body composition parameters including skeletal muscle mass index (SMI), intramuscular adipose tissue content (IMAC), visceral fat area (VFA), and visceral-to-subcutaneous adipose tissue area ratio (VSR) were evaluated by preoperative plain computed tomography imaging at the level of the third lumbar vertebra. This study defined sarcopenic obesity as a low SMI (male
