Hybrid stricturotomy plus balloon dilation versus stricturotomy alone for short Crohn's strictures
Official title: Hybrid Endoscopic Stricturotomy Plus Balloon Dilation Versus Endoscopic Stricturotomy Alone for Short Strictures (<3 cm) in Crohn's Disease (The HEIST Study)
Run by Asian Institute of Gastroenterology, India · NCT06958159 · Data updated 2026-11-12
This study will test whether adding balloon dilation to endoscopic stricturotomy helps adults with short Crohn's strictures have fewer symptoms and need fewer repeat procedures or surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–65 with symptomatic, non-angulated fibrotic or mixed Crohn's strictures shorter than 3 cm (up to two accessible strictures) in the colon or neo-terminal ileum are the intended participants.
✕Probably not a fit
Patients with predominantly inflammatory or ulcerated strictures, strictures longer than 3 cm, inaccessible locations, pregnancy, three or more strictures, or prior stricturotomy at the same site are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The HEIST trial randomly assigns adults with symptomatic, non-angulated Crohn's strictures under 3 cm in the colon or neo-terminal ileum to receive either endoscopic stricturotomy alone or stricturotomy followed by controlled balloon dilation. Procedures are performed during colonoscopy by experienced interventional endoscopists using standardized techniques and devices. Participants are followed at 1, 3, 6, and 12 months with symptom scoring, quality-of-life measures, adverse event monitoring, and documentation of any further endoscopic or surgical interventions. The primary focus is on durability of symptom relief and need for re-intervention over 12 months.
Why it matters
Potential benefit: If successful, the hybrid approach could reduce the need for repeat endoscopic procedures and surgery while improving symptom control and quality of life for patients with short fibrotic strictures.
How similar studies have gone: Endoscopic stricturotomy and balloon dilation are established treatments for short Crohn's strictures, but randomized data directly comparing the combined hybrid approach to stricturotomy alone are limited.
