Delayed repair of congenital diaphragmatic hernia (CDH) for days or longer has become standard, allowing improved stabilization for many, but potentially complicating treatment in severely affected infants who require extracorporeal membrane oxygenation (ECMO) and arrive unrepaired. Survival in left liver-up CDH, the most severe anatomic subset, averages 45% in published studies, with deaths often occurring in patients who failed to improve on ECMO and are repaired late, or not at all. Reliable early prediction of ECMO risk in these patients could identify the best candidates for repair before ECMO. We sought to predict ECMO risk in left liver-up CDH, and to further evaluate survival stratified by surgical timing in these patients. ⋯ Early repair of left liver-up CDH before ECMO results in improved survival. Multivariate models can accurately assess risk for ECMO at 1 hour of life, permitting stratification of CDH surgical timing to maximize survival potential while minimizing risk.

A significant number of patients undergo endovascular repair of abdominal aortic aneurysms (EVAR) outside the instructions for use (IFU). This study will examine various aortic neck features and their predictors of clinical outcomes. ⋯ Patients with neck features outside IFU can be treated with EVAR; however, they have higher rates of early and late type I endoleak, early intervention, and late death.

The initial experience with ABO incompatible (ABOi) orthotopic liver transplantations (OLTs) was dismal. In the current study, we investigated whether ABOi pediatric OLTs could achieve acceptable patient outcomes. The option for ABOi transplantation is vital because critically ill children have limited access to donor liver allografts. ⋯ This analysis revealed a significant improvement in the survival of ABOi liver transplant recipients in the modern era. Importantly, ABOi liver transplantation can be performed in recipients younger than 2 years of age with equivalent outcomes compared with ABO-identical recipients.

There are different views on the effects of resident involvement on surgical outcomes. We hypothesized that resident participation in surgical care does not appreciably alter outcomes. ⋯ We found substantial improvement in FTR with resident involvement, both in unmatched and propensity-matched comparisons. Senior-level resident participation seemed to attenuate, and even improve, surgical outcomes, despite slightly increased resource use. These results provide some reassurance about teaching paradigms.

The rate and consequences of reoperation after liver transplantation (LT) are unknown in the United States. ⋯ This is the first national study reporting that nearly one-third of transplant recipients undergo reoperation within 90 days of LT. Although necessary at times, reoperation is associated with increased risk of death at 1 year; however, it appears that the timing of these interventions can be critical, due to the type of intervention required. Early reoperative intervention does not appear to influence long-term outcomes, and delayed intervention (after 30 days) is strongly associated with decreased survival.
