Rectal stricture dilatation under direct vision with an over-the-scope BougieCap.

Why This Matters

A direct-vision push-type dilator (BougieCap) was used to safely dilate a low rectal stricture from Crohn's disease, allowing same-session sigmoidoscopy and biopsy and reported symptom improvement up to 18 months.

This could interest clinicians looking for alternative endoscopic dilation techniques for anorectal strictures.

Who Should Pay Attention

Endoscopists and gastroenterologists who treat Crohn's-related anorectal strictures; colorectal surgeons; clinicians caring for patients with obstructive defecation or severe low rectal stenosis due to Crohn's disease; patients considering endoscopic dilation options.

What To Know

This is a single-case report describing a technique (BougieCap dilator positioned over a gastroscope) rather than a comparative study.

The dilator achieved controlled gradual widening to a reported maximum of 12 mm (36 Fr) and maintained visualisation of the lumen throughout, which the authors highlight as an advantage for safety and for proceeding to diagnostic endoscopy and biopsy in the same session.

Because this is one case, the report does not establish how broadly effective or durable the technique is across patients, nor does it compare the BougieCap to other dilation tools or to endoscopic balloon dilation. The authors state prospective studies are needed to assess long-term usefulness and generalisability.

Clinical takeaways: The technique may be of interest to endoscopists managing benign low rectal strictures in Crohn's disease as a way to safely dilate under direct vision and enable immediate diagnostic work (sigmoidoscopy/biopsy). Patients with severe anorectal stenosis may require anaesthesia and specialist endoscopic expertise for this approach.

Keep In Mind

This is a single-case report (BMJ Case Reports) with partial abstract-level content. It describes technique and short-term follow-up in one patient; prospective studies are required to establish safety, efficacy, and long-term outcomes. The article is an abstract/partial extraction from PubMed.
