Factors associated with low graft regeneration in the early phase after living donor liver transplantation
Appropriate graft regeneration after living donor liver transplantation (LDLT) is crucial to avoid small‐for‐size syndrome. We enrolled 44 recipients who underwent ABO‐identical/compatible LDLT from December 2007 to August 2016 and determined possible factors associated with low graft regeneration a...

| description | Appropriate graft regeneration after living donor liver transplantation (LDLT) is crucial to avoid small‐for‐size syndrome. We enrolled 44 recipients who underwent ABO‐identical/compatible LDLT from December 2007 to August 2016 and determined possible factors associated with low graft regeneration after LDLT. Liver regeneration was calculated by the ratio of the graft size on postoperative day (POD) 7 ± 1 day (calculated by CT volumetry) to the size of the donated liver at implant. Postoperative outcomes were compared between the low and high regeneration groups. Median regeneration rate was 1.65‐fold. Regeneration rate was negatively correlated with graft‐to‐recipient weight ratio. Postoperative morbidity rates on POD 14‐90 were significantly higher in the low group compared with the high group (63% vs 18%, P = .03). Graft and patient survival in the low group were significantly worse than the high group (1‐year graft survival 73% vs 100%, P = .002; patient survival 82% vs 100%, P = .01). Cold ischemia time (CIT; per 10 minute; odds ratio [OR] =1.37) and platelet count |
