Nasogastric-tube decompression facilitates the pocket-creation method of gastric endoscopic submucosal dissection.

Trans‐anal Foley catheter facilitates endoscopic submucosal dissection of a distal rectal tumor

“…When performing rectal endoscopic submucosal dissection (ESD), collapsing of the lumen with frequent aspiration of gas can provide a thick submucosal tissue and provide stable endoscope maneuverability 1–3 . Recently, we introduced the placement of a trans‐anal nasogastric tube to allow gas and fluid to drain 4 .…”
