Balloon\u2010assisted endoscopic submucosal dissection (BA\u2010ESD) is useful in the treatment of proximal colorectal tumors where scope maneuverability is poor. Herein, we reported a case in which BA\u2010ESD was successfully performed using a long colonoscope with a guidewire, although the lesion could not be reached using the balloon\u2010assisted endoscopy technique with a therapeutic colonoscopy.<\/jats:p><jats:p>A 50\u2010year\u2010old man underwent a colonoscopy that revealed a tumor in the ascending colon. BA\u2010ESD was performed using a conventional therapeutic endoscope due to excessive intestinal elongation and poor endoscopic maneuverability. However, the transverse colon loop could not be reduced, and the total colonoscopy failed despite using balloon\u2010assisted endoscopy. The scope was then changed from a conventional colonoscope to a long colonoscope, inserted into the terminal ileum, and the loop was reduced. After the guidewire was placed at the terminal ileum and the long colonoscope was removed, a therapeutic colonoscopy with an overtube was inserted into the ascending colon without reforming the colonic loop, allowing safe BA\u2010ESD.<\/jats:p>","DOI":"10.1002\/deo2.259","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T02:54:40Z","timestamp":1686884080000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
