The BougieCap\u2019s clear walls allow direct vision, and conical shape enables controlled gradual dilatation to a maximum diameter of 12\u2009mm\/36 Fr facilitating subsequent flexible sigmoidoscopy using the same endoscope. A patient with a benign low rectal stenosis due to Crohn\u2019s disease underwent general anaesthesia for flexible sigmoidoscopy. Her stenosis symptoms included liquid seepage and obstructed defecation. A 12\u2009mm gastroscope could not be passed due to the severity of anorectal stenosis not admitting a little finger. Once the BougieCap dilator was positioned over the gastroscope, the stricture could be gently traversed under direct vision. The lumen was always visible. Flexible sigmoidoscopy and stricture biopsy then took place. At 6, 12 and 18 months follow-up, she reported a consistent improvement in symptoms. Prospective studies are required to establish long-term usefulness of this technique.<\/jats:p>","DOI":"10.1136\/bcr-2025-270997","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T18:15:22Z","timestamp":1790100922000},"page":"e270997","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rectal stricture dilatation under direct vision with an over-the-scope BougieCap"],"prefix":"10.1136","volume":"19","author":[{"given":"Joanna","family":"Park","sequence":"first","affiliation":[{"name":"Core Surgical Trainee - North Central East London, Barts Health NHS Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamzin","family":"Cuming","sequence":"additional","affiliation":[{"name":"Colorectal Surgery, Homerton Hospital, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7903-5243","authenticated-orcid":false,"given":"Iain","family":"Ewing","sequence":"additional","affiliation":[{"name":"Gastroenterology, Homerton University Hospital NHS Foundation Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"2026092211151700000_19.9.e270997.1","doi-asserted-by":"crossref","first-page":"401","DOI":"10.1080\/17474124.2021.1854732","article-title":"Prevention and Treatment of Stricturing Crohn\u2019s Disease \u2013 Perspectives and Challenges","volume":"15","author":"Sleiman","year":"2021","journal-title":"Expert Rev Gastroenterol Hepatol"},{"key":"2026092211151700000_19.9.e270997.2","unstructured":"Ovesco Endoscopy AG .
