Abstract
To compare the outcome of small-for-size grafts versus standard-size grafts regarding the frequency of postoperative complications, early graft dysfunction, and 1-year survival. Retrospective cohort study. Pir Abdul Qadir Shah Jeelani Institute of Medical Sciences (PAQSJIMS) Hospital, Gambat, Sindh, Pakistan from March 2019 to April 2020. A total of 147 living donor liver transplant recipients' data were retrospectively evaluated. Study participants were divided into two groups; small-for-size graft (GRWR <0.8%) and standard-size graft (GRWR >0.8%). Recipients' demographics, graft characteristics, operative parameters, postoperative complications, and graft survival were compared in both groups. Out of 147 recipients, 21 were found to have small-for-size graft, while 126 patients had the standard-size graft. Mean GRWR in small-for-size graft group was 0.73 + 0.4 (0.63-0.79), while 0.93 + 0.82 (0.81-3.0) in standard-size graft group. A statistically significant difference was found while comparing body mass index (p <0.001), hepatic venous reconstruction (p = 0.013), and liver attenuation index (p <0.001) between both study groups. While all other recipient and donor characteristics, demographical data, operative variables, postoperative lab, and complications were comparable in both groups (p >0.05). Kaplan-Meier analysis showed that 1-year survival rate for small-for-size graft recipients was 90.5%, while the survival rate for the standard-size graft was 96.0% (p = 0.272). Frequency of post-op complications was comparable in both groups. The graft survival in small-for-size grafts was as good as for standard-size grafts. Key Words: Living donor liver transplantation, GRWR, Small-for-size graft, Standard-size graft.
