Massive intraoperative bleeding during liver transplantation often requires large amounts of blood products. The goal of this study was to investigate long-term outcomes of living donor liver transplantation (LDLT) recipients with hepatocellular carcinoma (HCC) who underwent intraoperative use of intraoperative blood salvage (IBS) and leukocyte depletion filter (LDF). In this study, we included 230 LDLT recipients with HCC from two transplantation centers, between February 2002 and December 2007. Group 1 patients (n = 121) underwent intraoperative IBS with LDF and group 2 patients (n = 109) did not. The amount of autotransfused, filtered red blood cells (RBCs) in group 1 was 1590.2 ± 1486.8 ml, which corresponded to 5.9 units of allogenic leukocyte-depleted RBCs saved. The incidences of renal dysfunction, postoperative bleeding, and urinary tract infection in group 2 were higher than in group 1 (P < 0.05). Recurrence-free survival rates for 1, 3, and 5 years were 91.3%, 83.3%, and 83.3%, respectively, in group 1, and 84.6%, 79.0%, and 77.4%, respectively, in group 2 (P = 0.314). IBS using LDF does not increase the risk of cancer recurrence during LDLT for recipients with HCC. Therefore, the use of IBS with LDF appears to be safe for LDLT recipients with HCC.

We compared postoperative hepatic and renal functions between the two inhalational anesthetics, desflurane and sevoflurane in living donors undergoing right hepatectomy. Seventy‐four adult donors were randomly allocated into Des group (n = 37) and sevo group (n = 37). Before the induction of anesthesia, morphine sulfate 400 μg was injected intrathecally. Anesthesia was maintained with one minimum alveolar concentration (MAC) of deflurane or sevoflurane plus continuous intravenous remifentanil. Liver and renal function tests were performed and analysed at preoperative period, immediately after operation, and on 1st, 2nd, 3rd, 5th, 7th, and 30th postoperative days (PODs). Aspartate aminotransferase (AST) showed significant elevations from the day of surgery to POD 3 and alanine aminotransferase (ALT) was significantly elevated on POD 1 and POD 3 in the sevo group. Albumin level was significantly lower on POD 2 in the sevo group. Creatinine was significantly higher on POD 3 and POD 30 and estimated glomerular filtration ratio was significantly lower on POD 3 and POD 30 in the sevo group. No patient developed hepatic or renal failures. The results of our study showed better postoperative hepatic and renal function test with desflurane than sevoflurane at equivalent dose of 1 MAC in living donors undergoing right hepatectomy, but further study is required to evaluate clinical importance.

This study was aimed to evaluate the association between preoperative high-sensitivity cardiac troponin I (hs-cTnI) level and mortality in patients undergoing liver transplantation (LT). From January 2011 to May 2016, preoperative hs-cTnI level was measured in consecutive 487 patients scheduled for LT. Patients with elevated preoperative hs-cTnI were compared with those who had normal level. The primary outcome was all-cause death in follow-up period of 30 days to 1 year after operation. Of the 487 patients, 58 (11.9%) had elevated preoperative hs-cTnI and 429 (88.1%) had normal preoperative hs-cTnI. In multivariate analysis, the rate of 1-year mortality and 30-day mortality were higher in elevated preoperative hs-cTnI group (hazard ratio [HR], 3.69; confidence interval [CI] 95%, 1.83–7.42; p < 0.001, HR, 6.61; CI, 1.91–22.82; p = 0.003, respectively). After adjustment with inverse probability weighting (IPW), the incidence of 1-year mortality and 30-day mortality were higher in elevated group (HR, 4.66; CI, 3.56–6.1; p < 0.001, HR, 10.31; CI, 6.39–16.66; p < 0.001, respectively). In conclusion, this study showed that in patients who underwent LT, elevation of preoperative hs-cTnI level was associated with 1-year mortality and 30-day mortality.

Background This study aimed to evaluate risk factors and postoperative clinical outcome associated with myocardial injury detected by an elevated high-sensitivity cardiac troponin I (hs-cTnI) immediately after living donor liver transplantation (LDLT). Methods Between January 2011 and December 2016, 313 adult recipients undergoing LDLT, with normal preoperative hs-cTnI were selected. Hs-cTnI level above 0.04 ng/mL according to 99th percentile reference limit was defined as myocardial injury. The recipients were divided into 2 groups according to postoperative hs-cTnI measured immediately after LDLT and postoperative clinical outcome was compared. Results The primary outcome was composite of death or graft failure during hospital stay. Risk factors associated with myocardial injury during LDLT was also evaluated. Of the 313 recipients with normal preoperative hs-cTnI level, 159 (50.8%) had elevated hs-cTnI level and 154 (49.2%) had normal level after LDLT. The incidence of all-cause death or graft failure during hospital stay was significantly higher in recipients with myocardial injury (1.9% vs 7.6%; hazard ratio, 4.15; 95% confidence interval, 1.01-17.14; P = 0.049). The same result was shown in propensity-matched population (0.9% vs 9.0%; hazard ratio, 9.08; 95% confidence interval, 1.16-71.01; P = 0.04). The results during 1-year follow-up were not consistent. Female sex, ischemia time, and presence of postreperfusion syndrome were independent predictors of myocardial injury during LDLT. Conclusions Myocardial injury detected by elevation of hs-cTnI level immediately after LDLT was independently associated with adverse outcome during hospital stay.
