Peroral endoscopic myotomy for hypercontractile (Jackhammer) esophagus: A retrospective multicenter series with long-term follow-up.

Introduction: Long-term outcome data are limited for non-achalasia esophageal motility disorders treated by peroral endoscopy myotomy (POEM) as a separate group. We investigated a subset of symptomatic patients with hypercontractile esophagus (Jackhammer esophagus).

Methods: Forty two patients (mean age 60.

Cold Versus Hot Snare Endoscopic Resection of Large Nonpedunculated Colorectal Polyps: Randomized Controlled German CHRONICLE Trial.

Background & Aims: Endoscopic mucosal resection (EMR) is standard therapy for nonpedunculated colorectal polyps ≥20 mm. It has been suggested recently that polyp resection without current (cold resection) may be superior to the standard technique using cutting/coagulation current (hot resection) by reducing adverse events (AEs), but evidence from a randomized trial is missing.

Methods: In this randomized controlled multicentric trial involving 19 centers, nonpedunculated colorectal polyps ≥20 mm were randomly assigned to cold or hot EMR.

Integration of robotic in the reprocessing and transfer of endoscopes.

Optimal hygiene is crucial for patients undergoing flexible endoscopy. Reprocessing is currently influenced by manual procedures performed by endoscopy staff. To overcome this limitation, we designed and evaluated the integration of robotic application for an automated endoscope processing pathway.
