Background.
No data exist to evaluate how hepatectomy time (HT), in the context of donation after cardiac death (DCD) procurement, impacts short- and long-term outcomes after liver transplantation (LT). In this study, we analyze the impact of the time from aortic perfusion to end of hepatectomy on outcomes after DCD LT in the United Kingdom.
Methods.
An analysis of 1112 DCD donor LT across all UK transplant centers between 2001 and 2015 was performed, using data from the UK Transplant Registry. Donors were all Maastricht Category III. Graft survival after transplantation was estimated using Kaplan-Meier method and logistic regression to identify risk factors for primary nonfunction (PNF) and short- and long-term graft survivals after LT.
Results.
Incidence of PNF was 4% (40) and in multivariate analysis only cold ischemia time (CIT) longer than 8 hours (hazard ratio [HR], 2.186; 95% confidence interval [CI], 1.113–4.294; P = 0.023) and HT > 60 minutes (HR, 3.669; 95% CI, 1.363–9.873; P = 0.01) were correlated with PNF. Overall 90-day, 1-, 3-, and 5-year graft survivals in DCD LT were 91.2%, 86.5%, 80.9%, and 77.7% (compared with a donation after brain death cohort in the same period [n = 7221] 94%, 91%, 86.6%, and 82.6%, respectively [P < 0.001]). In multivariate analysis, the factors associated with graft survival were HT longer than 60 minutes, donor older than 45 years, CIT longer than 8 hours, and recipient previous abdominal surgery.
Conclusions.
There is a negative impact of prolonged HT on outcomes on DCD LT and although HT is 60 minutes or longer is not a contraindication for utilization, it should be part of a multifactorial assessment with established prognostic donor factors, such as age (>45 y) and CIT (>8 h) for an appropriately selected recipient.
Background: While mortality rates after radical gastrectomy have decreased, there is considerable morbidity after D2 lymphadenectomy. In this study, we assessed the perioperative results of D2 gastrectomy for gastric cancer. Materials: Data of 159 patients who underwent D2 gastrectomy for gastric adenocarcinoma at Tata Memorial Hospital was analyzed for interim analysis. The extent of resection, blood loss, transfusions, duration of hospitalization, number of lymph nodes dissected, complications, morbidity and mortality were analyzed. Results: 130 and 29 patients underwent distal and total gastrectomy, respectively (2002–2005) by single specialized surgical unit. Median age was 55 years (range 21–78) and blood loss was 450 ml (range 100–2,200 ml). The median duration of hospitalization was 13 days (range 7–52 days). The median number of dissected lymph nodes was 15 (range 2–46). Minor and major morbidity rate was 4.4 and 4.4% respectively. Mortality rate was 1.25%. Conclusion: Morbidity and mortality following D2 lymphadenectomy is low in this first prospective study from India. With Japan and Western countries having polarized views on D2 lymphadenectomy, future international multicenter trials could also incorporate data such as ours from areas of high incidence of gastric cancer since perioperative outcomes would no longer cloud their results and might provide a better global perspective on D2 lymphadenectomy.
A late referral was associated with a higher incidence of post-treatment complications, greater need for invasive procedures and a longer recovery period. These observations support the need for early patient transfer to a tertiary institution following BDI.
The incidence of SFSS in grafts with a GRWR <0.8 is more than in GRWR ≥0.8; however, the low GRWR does not appear to impact perioperative outcomes or graft survival.
This study supports the use of DCD renal grafts with comparable long-term survival and function to DBD grafts. The use of EC-DCD grafts is justified in selected recipients and provides acceptable function and survival advantages over dialysis.
