AWATER-AIDED PROCEDURE can facilitate deeper intubation during balloon-assisted endoscopy by reducing large loop formation. A narrow, collapsed lumen underwater or bleeding following a mucosal injury by scope contacts can reduce endoscopic visibility. A new super-soft, highly flexible hood (Space adjuster; TOP Corporation, Tokyo, Japan) made of silicon and designed for therapeutic endoscopy, including endoscopic submucosal dissection or peroral endoscopic myotomy, was used to improve visibility during water-aided double-balloon endoscopy (DBE). A man in his 50s was referred to our hospital for diagnosis and treatment of a small bowel mass detected on computed tomography. We performed trans-oral DBE (EN-580T; FUJIFILM Medical, Co., Tokyo, Japan), using the new transparent super-soft hood under conscious sedation (Fig. 1). Water irrigation using sterile saline solution was performed by
