Background.
The innovative pure laparoscopic living donor right hepatectomy (LLDRH) procedure for liver transplantation has never been fully compared to open living donor right hepatectomy (OLDRH). We aimed to compare the donor safety and graft results of pure LLDRH to those of OLDRH.
Methods.
From May 2013 to July 2017, 288 consecutive donors underwent either OLDRH (n = 197) or pure LLDRH (n = 91). After propensity score matching, 72 donors were included in each group. The primary outcome was postoperative complications during a 90-day follow-up period. Comprehensive complication index, duration of hospital stay, need for additional pain control, readmission, and donor outcomes were also compared.
Results.
The incidence of major complication during the 90-day follow-up was higher in the LLDRH group than the OLDRH group (6.6% vs 15.4%, P = 0.017) but was not statistically significant in propensity-matched analysis (11.1% vs 13.9%, odds ratio [OR], 1.29; 95% confidence interval [CI], 0.47-3.51; P = 0.62). A right hepatic duct <1 cm was independently associated with complication in the pure LLDRH group (odds ratio, 4.01; 95% confidence interval, 1.08-14.99; P = 0.04).
Conclusions.
In the initial 91 pure LLDRH cases, incidence of major complication was higher than in the OLDRH group, but the difference was not significant in propensity-matched analysis. A right hepatic duct verified as <1 cm may be related to increased frequency of complications in pure LLDRH donors. Further analysis is needed.
PurposeWhereas continuous renal replacement therapy (CRRT) has been utilized during liver transplantation (LT), there was a lack of evidence to support this practice. We investigated the adverse events at the perioperative periods in recipients of LT who received preoperative CRRT without intraoperative CRRT.MethodsWe retrospectively reviewed medical records of adult patients (age ≥ 18 years) who received LT between December 2009 and May 2015. Perioperative data were collected from the recipients, who received preoperative CRRT until immediately before LT, because of refractory renal dysfunction.ResultsOf 706 recipients, 42 recipients received preoperative CRRT. The mean (standard deviation) Model for end-stage liver disease score were 49.6 (13.4). Twenty-six point two percent (26.2%) of recipients experienced the serum potassium > 4.5 mEq/L before reperfusion and treated with regular insulin. Thirty-eight point one percent (38.1%) of recipients were managed with sodium bicarbonate because of acidosis (base excess < −10 mEq/L throughout LT). All patients finished their operations without medically uncontrolled complications such as severe hyperkalemia (serum potassium > 5.5 mEq/L), refractory acidosis, or critical arrhythmias. Mortality was 19% at 30 day and 33.3% at 1 year.ConclusionAlthough intraoperative CRRT was not used in recipients with severe preoperative renal dysfunction, LT was safely performed. Our experience raises a question about the need for intraoperative CRRT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
