Comparative Study Clinical Trial
Emergency Computed Tomography Predicts Caustic Esophageal Stricture Formation.
Endoscopy is the best predictor of stricture formation after caustic ingestion. ⋯ Emergency CT outperforms endoscopy in predicting esophageal stricture formation after caustic ingestion. Emergency endoscopy evaluation after caustic ingestion is not indispensable.

Clinical Trial
Intraoperative Near-infrared Imaging Can Identify Neoplasms and Aid in Real-time Margin Assessment During Pancreatic Resection.
To determine if intraoperative near-infrared (NIR) imaging carries benefit in resection of pancreatic neoplasms. ⋯ Second window ICG reliably accumulates in invasive pancreatic malignancies and provides real-time feedback during pancreatectomy. NIR imaging may help to assess the response to neoadjuvant therapy.

Observational Study
Current Management and Predictive Factors of Lymph Node Metastasis of Appendix Neuroendocrine Tumors: A National Study from the French Group of Endocrine Tumors (GTE).
The primary endpoint was to analyze the predictive factors of lymph node involvement (LN+). ⋯ In the largest study using the latest pathological criteria for completion RHC in A-NET, a quarter of patients had residual tumor. Further studies are warranted to demonstrate the survival impact of RHC in this setting.

Comparative Study
Stent Design Affects Femoropopliteal Artery Deformation.
Poor durability of femoropopliteal artery (FPA) stenting is multifactorial, and severe FPA deformations occurring with limb flexion are likely involved. Different stent designs result in dissimilar stent-artery interactions, but the degree of these effects in the FPA is insufficiently understood. ⋯ Peripheral self-expanding stents significantly affect limb flexion-induced FPA deformations, but in different ways. Although certain designs seem to accommodate some deformation modes, no device was able to match all FPA deformations.

To develop and validate a preoperative frailty index (pFI) for use in population-based health administrative (HA) data. ⋯ A preoperative FI derived from HA data is a robust method to measure frailty in elective and emergency patients. Generalizable FIs should be considered a standard approach to population-level study of surgical frailty.
