Multicenter Study
Perihilar Cholangiocarcinoma-Novel Benchmark Values for Surgical and Oncological Outcomes From 24 Expert Centers.
The aim of this study was to define robust benchmark values for the surgical treatment of perihilar cholangiocarcinomas (PHC) to enable unbiased comparisons. ⋯ Surgery for PHC remains associated with high morbidity and mortality with now the availability of benchmark values covering 21 outcome parameters, which may serve as key references for comparison in any future analyses of individuals, group of patients or centers.

Multicenter Study Comparative Study
Presentation, Treatment, and Prognosis of Esophageal Carcinoma in A Nationwide Comparison of Sweden and the Netherlands.
This population-based study aimed to compare presentation, treatment allocation and survival of potentially curable esophageal cancer patients between Sweden and the Netherlands. ⋯ Swedish patients with potentially curable esophageal cancer were less frequently allocated to curative treatment, and showed lower survival compared to Dutch patients. The less pronounced inter-country survival difference after curative treatment suggests that the overall survival difference could at least partly be due to relative undertreatment of Swedish patients. Shared curative treatment thresholds across Europe may help improve survival of esophageal cancer patients.

Multicenter Study Observational Study
Predicting Intraoperative Difficulty of Open Liver Resections: The DIFF-scOR Study, An Analysis of 1393 Consecutive Hepatectomies From a French Multicenter Cohort.
The aim of this study was to build a predictive model of operative difficulty in open liver resections (LRs). ⋯ The DIFF-scOR accurately predicts open-LR difficulty and may be used for various purposes in clinical practice and research.

The aim of this study was to evaluate whether neoadjuvant therapy (NAT) critically influenced microscopically complete resection (R0) rates and long-term outcomes for patients with pancreatic ductal adenocarcinoma who underwent pancreatoduodenectomy (PD) with portomesenteric vein resection (PVR) from a diverse, world-wide group of high-volume centers. ⋯ Patients with PDAC of the pancreatic head expected to undergo venous reconstruction should routinely be considered for NAT.

To investigate the association between hospital volume and failure to rescue (FtR), after open repair (OAR), and endovascular repair (EVAR) of intact abdominal aortic aneurysms (AAA) among centers participating in the VASCUNET and International Consortium of Vascular Registries. ⋯ In this multi-national dataset, FtR rate after intact AAA repair with EVAR and OAR is significantly associated with hospital volume. Hospitals in the top volume quartiles achieve the lowest mortality after a complication has occurred.
