Background And Objective: In clinical practice, valve-sparing aortic root replacement surgery primarily addresses left ventricular dysfunction in patients due to severe aortic regurgitation, but there is controversy regarding the choice of surgical technique. In order to investigate which type of valve-sparing aortic root replacement surgeries can achieve better blood flow conditions, this study examines the impact of changes in the geometric morphology of the aortic root on the hemodynamic environment through numerical simulation.
Methods: An idealized model of the aortic root was established based on data obtained from clinical measurements, including using the model of the aortic root without significant lesions as the control group (Model C), while using surgical models of leaflet reimplantation with tubular graft (Model T), leaflet reimplantation with Valsalva graft (Model V), and the Florida sleeve procedure (Model F) as the experimental groups.

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach for strategies to diagnose and manage GERD. This document was developed using the Grading of Recommendations Assessment, Development, and Evaluation framework and serves as an update to the 2014 ASGE guideline on the role of endoscopy in the management of GERD. This updated guideline addresses the indications for endoscopy in patients with GERD as well as in the emerging population of patients who develop GERD after sleeve gastrectomy or peroral endoscopic myotomy.

Biliopancreatic diversion with duodenal switch (BPD-DS) and single anastomosis duodeno-ileostomy with sleeve (SADI-S) are associated with superior and sustained weight loss outcomes. Despite their growing popularity, long-term safety profiles, particularly the risk of internal hernia (IH), remain underexplored. This study aimed to evaluate the incidence and characteristics of IH following BPD-DS and SADI-S procedures, comparing their clinical presentation, diagnostic methods, and outcomes.
