Abstract

Objective: To investigate the relationship between psoas muscle index (PMI) and early postoperative survival rate and the incidence of complications after liver transplantation in adults. Methods: The clinical data of 225 patients (male, n=184; female, n=41) underwent liver transplantation at the Organ Transplantation Department of First Central Clinic Institute of Tianjin Medical University from January 2014 to December 2016 were analyzed, retrospectively.Original disease: hepatitis B liver cirrhosis(44 cases), hepatitis C cirrhosis(10 cases), autoimmune liver cirrhosis(29 cases), other benign liver diseases(24 cases), liver cirrhosis with liver cancer(116 cases), hilar cholangiocarcinoma(1 case) and hepatic vascular sarcoma(1 case). The area of bilateral psoas muscle on the lower edge level of the third lumbar vertebral body was measured through preoperative CT image.The PMI was calculated using this formula: bilateral psoas muscle area (mm(2))/the square of the body height (m(2)). According to the receiver operating characteristic curve and cut-off values, the male and female patients were divided into low PMI group and high PMI group respectively.The χ(2) test, Fisher exact test and t-test was used to compare the difference...Continue Reading
