Impact of Blood Loss and Intraoperative Blood Transfusion During Liver Transplantation on the Incidence of Early Biliary Complications and Mortality.

Biliary complications are one of the most serious and dangerous complications following liver transplantation. Factors that may determine their occurrence are still being assessed. The retrospective analysis of 239 consecutive liver transplantations (LT) performed between January 2013 and December 2018 was conducted in compliance with the Helsinki Congress and the Istanbul Declaration. We divided recipients into 2 groups depending on whether biliary complications occurred. The first (biliary complication [BC group]) consisted of patients who developed biliary complications (n = 41) and the second (nonbiliary complications [NBC group]) without them (n = 198). Demographic and statistical data analysis showed no differences between the groups in terms of age, Model for End-Stage Liver Disease with sodium serum concentration (MELD-Na) score, and average cold or warm ischemia time. In comparison, estimated intraoperative blood loss, 1341 mL in the NBC and 1399 mL in the BC, was not significantly different, as were the number of transfused red blood cells (RBC) units, which were respectively 1.7 and 2.1 (P = ns). The recipients' hemoglobin levels just before surgery were (11.5 g/dL vs 11.6 g/dL; P = ns) and after transplantation (9.8 g/dL vs 9.8 g/dL; P = ns). Eleven patients died within 30 days of transplantation. This group was characterized by a higher MELD-Na score (25 vs 17; P = .01), lower pretransplant hemoglobin level (10 g/dL vs 11.6 g/dL; P = .02), and the number of transfused RBC units (3.3 vs 1.7; P = .01). However, there was no correlation between intraoperative blood loss, the number of transfused RBC units, pre- and postoperative hemoglobin levels, and the incidence of biliary complications after LT. Lower pretransplant hemoglobin levels and a higher amount of intraoperatively transfused blood products were associated with a higher fatality rate after LT.
