Endoscopic full-thickness resection (EFTR) has emerged as a transformative technique for managing gastrointestinal (GI) lesions, previously deemed unsuitable for endoscopic removal. Unlike conventional endoscopic resection methods, such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), EFTR enables en bloc excision of both intraluminal and subepithelial lesions by resecting all layers of the GI wall, followed by defect closure to prevent complications. The introduction of the full-thickness resection device (FTRD) has significantly enhanced the feasibility and safety of EFTR, particularly in the colon and upper GI tract, with increasing adoption worldwide.

Background And Aims: Endoscopic retrograde cholangiopancreatography (ERCP), in surgically altered anatomy (SAA), can be challenging and the optimal technique selection remains debatable. Most common foregut interventions resulting to this burden consist of Billroth II gastrectomy, Whipple surgery and Roux-en-Y anastomoses, including gastric by-pass. This systematic review, with meta-analysis, aimed to compare the rates of successful enteroscope-assisted (EA)-, endosonography-directed transgastric- (EDGE), and laparoscopy-assisted (LA)-ERCP.

Background: A high-cholesterol diet (HCD) induces vascular atherosclerosis through vascular inflammatory and immunological processes via TLRs. The aim of this study is to investigate the mRNA expression of TLRs and other noxious biomarkers expressing inflammation, fibrosis, apoptosis, and cardiac dysfunction in the rabbit myocardium during (a) high-cholesterol diet (HCD), (b) normal diet resumption and (c) fluvastatin or rosuvastatin treatment.

Methods: Forty-eight male rabbits were randomly divided into eight groups ( = 6/group).
