Abstract
Background: Endoscopic therapy is often difficult to achieve particularly when the field of view of the lesion is poor due to contamination of mucus and blood. We developed five different types of end hoods that facilitate endoscopic procedures by simultaneously allowing various treatments and irrigation of the site.Methods: The end‐hood pieces were fabricated by drilling a side hole in the cap portion of conventional transparent hoods, then the irrigation tube was glued to the exterior surface of the hole. The fabricated transparent hood was placed at the tip of the endoscope.Results: Types 1 and 2 were useful for upper‐gastrointestinal (GI) hemorrhage, type 3 for lower‐GI hemorrhage, type 4 for endoscopic submucosal dissection and type 5 for endoscopic mucosal resection.Conclusions: With this method, endoscopic procedure is easy and economical, as therapeutic procedures can be performed under irrigation using a conventional endoscopy.
