Background: Surgery is the first-choice treatment for malignant intestinal obstruction (MIO); however, many patients are deemed unfit for surgery. Endoscopic ultrasound-guided entero-colostomy (EUS-EC) with a lumen-apposing metal stent (LAMS) could represent a new treatment option., Methods: Consecutive patients undergoing EUS-EC for MIO from November 2021 to September 2023 at four European tertiary referral centers were retrospectively enrolled. Multidisciplinary meetings determined whether patients were unsuitable for surgery or colonic stent placement, or refused surgery. The primary outcome was technical success of EUS-EC and secondary outcomes were clinical outcome, safety, and hospital stay., Results: 12 patients were enrolled (median age 72.5 [range 42-85] years; 58.3% female). Colonic adenocarcinoma was the primary tumor in 75.0% of patients and 91.7% had stage IV disease. Technical success was 100%. No LAMS misdeployment or other procedural adverse events occurred; three patients (25.0%) had severe post-procedural complications. Clinical success was achieved in 10 patients (83.3%), with 5 (50.0%) resuming chemotherapy after the procedure. Median post-procedural hospital stay was 9 (1-20) days and median overall survival was 47.5 (2-270) days., Conclusions: EUS-EC was a feasible technique and could be considered a possible alternative to standard approaches for MIO in highly selected patients., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

This joint ASGE-ESGE guideline provides an evidence-based summary and recommendations regarding the role of endoscopic bariatric and metabolic therapies (EBMTs) in the management of obesity. The document was developed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. It evaluates the efficacy and safety of EBMT devices and procedures that currently have CE mark or FDA-clearance/approval, or that had been approved within five years of document development. The guideline suggests the use of EBMTs plus lifestyle modification in patients with a BMI of ≥30 kg/m 2 , or with a BMI of 27.0-29.9 kg/m 2 with at least 1 obesity-related comorbidity. Furthermore, it suggests the utilization of intragastric balloons and devices for endoscopic gastric remodeling (EGR) in conjunction with lifestyle modification for this patient population., Competing Interests: The following authors disclosed financial relationships: P.
