REVUR is a safe and effective technique for treatment of primary unilateral VUR. The procedure is easy and fast to perform thanks to the 6° of freedom of robotic arms. The learning curve is short and it is useful to begin the robotics experience with a surgeon expert in robotic surgery as proctor on the 2nd robot console. The high cost and the diameter of instruments remain the main challenges of robotics applications in pediatric urology.
Background: In Italy, 20 minutes of continuous, flat-line electrocardiogram are required for death declaration, which significantly increase the risks of DCD LT. Despite prolonged warm ischemia time, Italian centers reported good outcomes in controlled DCD (cDCD) LT by combining normothermic regional and end-ischemic machine perfusion. However, data on uncontrolled DCD (uDCD) LT performed by this approach are lacking. Patients and Methods: This was a multicenter, retrospective study performed at three large volume centers comparing clinical outcomes of uncontrolled versus controlled DCD LT. The aim of the study was to assess outcomes of sequential normothermic regional perfusion (NRP) and end-ischemic machine perfusion in uncontrolled DCD liver transplantation (LT) Results: Of 153 DCD donors evaluated during study period, 40 uDCD and 59 cDCD grafts were transplanted (utilization rate 52% vs. 78%, p = 0.004). Recipients of uDCD grafts had higher MEAF (4.9 vs. 3.5, p < 0.001) and CCI score at discharge (24.4 vs. 8.7, p = 0.026), longer ICU stay (5 vs. 4 d, p = 0.047) and a trend towards more severe AKI. At multivariate analysis, 90-days graft loss was associated with recipient BMI and lactate downtrend during NRP. One-year graft survival was lower in uDCD (75% vs. 90%, p = 0.007) but became comparable when non-liver-related graft losses were treated as censors (77% vs. 90%, p = 0.100). Incidence of ischemic cholangiopathy was 10% in uDCD versus 3% in cDCD, p = 0.356. Conclusions: uDCD LT with prolonged warm ischemia is feasible by the sequential use of NRP and end-ischemic machine perfusion. Proper donor and recipient selection are key in achieving good outcomes in this setting.
BackgroundZenker's diverticulum (ZD) is a protrusion of the pharyngeal mucosa and submucosa through Killian's triangle, between the inferior pharyngeal constrictor muscle and the cricopharyngeal muscle. The underling mechanism of formation is the pulsion against a dyscinetic upper esophageal sphincter (UES). It is a rare disorder and mostly affects elderly people, but still, it is the most frequent esophageal diverticulum. Its incidence is reported to be
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.
