Three case scenarios are presented in this month’s e-Video section. The one from Endoscopy shows a single-session combined submucosal dissection and endoscopic full-thickness resection for a recurrent rectal polyp. The DEN case demonstrates treatment of Zenker’s diverticulum by total septum myotomy throughout a submucosal tunnel (Z‐POEM).

In the VideoGIE contribution, the authors demonstrate the usefulness and safety of a novel multifunctional snare, for colorectal precutting EMR and for hybrid endoscopic submucosal dissection of a sessile serrated polyps.

We are grateful to the editors of these journals for sharing their links with our WEO e-Newsletter community.
