Multicenter Study
The Importance of Registries in the Postmarketing Surveillance of Surgical Meshes.
To assess the role of registries in the postmarketing surveillance of surgical meshes. ⋯ The importance of real-world data for postmarketing surveillance of surgical meshes has been demonstrated in this registry-based study. Randomized controlled trials are needed for premarket approval of new devices. The role of sponsorship of device studies by the manufacturing company must be taken into account.

Randomized Controlled Trial Multicenter Study
Surgicopathological Quality Control and Protocol Adherence to Lymphadenectomy in the CRITICS Gastric Cancer Trial.
The purpose of this study was to evaluate surgicopathological quality and protocol adherence for lymphadenectomy in the CRITICS trial. ⋯ Surgical quality in the CRITICS trial was excellent, with a MI of 1. Surgicopathological compliance improved over the years. This might be explained by the quality assurance program within the study and centralization of gastric cancer surgery in the Netherlands.

Comparative Study
Surgeon Experience and Medicare Expenditures for Laparoscopic Compared to Open Colectomy.
To quantify the extent to which payments for laparoscopic and open colectomy are influenced by a surgeon's experience with laparoscopy. ⋯ This population-based study demonstrates that differences in payments between laparoscopic and open colectomy are influenced by surgeon experience. The laparoscopic approach does not reduce payments for patients whose surgeons have limited experience with the procedure.

What are the clinical outcomes of early versus delayed laparoscopic cholecystectomy (LC) in acute cholecystitis with more than 72 hours of symptoms? ⋯ ELC for acute cholecystitis even beyond 72 hours of symptoms is safe and associated with less overall morbidity, shorter total hospital stay, and duration of antibiotic therapy, as well as reduced cost compared with delayed cholecystectomy.

The aim of this study was to decipher the true importance of R0 versus R1 resection for survival in pancreatic ductal adenocarcinoma (PDAC). ⋯ Resection margin is not a valid prognostic marker in publications before 2010 due to heterogeneity of cohorts and lack of standardized histopathological examination. Within standardized pathology protocols, R-status' prognostic validity may be primarily confined to pancreatic head cancers.
