Abstract

BACKGROUND Successful graft regeneration is important in living-donor liver transplantation (LDLT) because partial liver grafts are used. Early allograft dysfunction (EAD) is an intermediate outcome that affects the long-term postoperative course in liver transplantation. The aim of the present study was to investigate liver graft regeneration under EAD development in LDLT. MATERIAL AND METHODS The data of 226 patients who underwent LDLT from September 2010 to July 2014 were retrospectively analyzed. The patients were classified into 2 groups: one with and one without EAD. Graft regeneration, functional recovery, and long-term patient survival were compared between the 2 groups. RESULTS The grafts grew more vigorously in the EAD group than in the non-EAD group, as evidenced by the larger absolute (ALV) and relative liver volumes (RLV) of the former on postoperative days (POD) 7 and 21. The median (interquartile range) RLVs of the non-EAD group versus the EAD group were as follows: 55.2 (47.9-65.8) vs. 53.7 (46.6-64.5)% preoperatively, p>0.05; 76.1 (66.9-85.7) vs. 86.7 (73.9-96.8)% on POD 7, p<0.01; 79.6 (69.3-91.2) vs. 93.7 (79.6-101.6)%, p<0.01 on POD 21. In the early postoperative period, hepatic function, measured as total b...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
