Multicenter Study
New Nodal Staging for Primary Pancreatic Neuroendocrine Tumors: A Multi-institutional and National Data Analysis.
To determine the prognostic role of metastatic lymph node (LN) number and the minimal number of LNs for optimal staging of patients with pancreatic neuroendocrine tumors (pNETs). ⋯ Regional lymphadenectomy of at least 8 lymph nodes was necessary to stage patients accurately. The proposed nodal staging of N0, N1, and N2 optimally staged patients.

Meta Analysis
Meta-Analysis and Systematic Review of the Use of a Prosthetic Mesh for Prevention of Parastomal Hernia.
The primary endpoint of this meta-analysis was the PSH rate at 1 year of follow-up with or without the use of a mesh. ⋯ Based on this meta-analysis including the latest RCT on the prevention of PSH, the use of a mesh should not be recommended.

Multicenter Study
Mapping of Lymph Node Metastasis From Esophagogastric Junction Tumors: A Prospective Nationwide Multicenter Study.
The aim of the study was to determine the optimal extent of lymph node dissection for the 2 histological types of esophagogastric junction (EGJ) tumors based on the incidence of metastasis in a prospective nationwide multicenter study. ⋯ The study accurately identified the distribution of lymph node metastases from EGJ tumors and the optimal extent of subsequent lymph node dissection.
