Brief summary
Two thirds of patients with Crohn's disease require intestinal surgery at some time in their life. Intestinal strictures, that is narrowing of the bowel due to inflammation and scarring, are the most common reason for surgery. Despite the high frequency, associated disability, and cost there are no are no treatment strategies that aim to improve the outcome of this disease complication. The STRIDENT (stricture definition and treatment) studies aim to develop such strategies.
Detailed description
Prospective randomised controlled study. Patients with Crohn's Disease and symptomatic stricture(s) will undergo randomisation to receive standard or intensive endoscopic therapy.
Interventions
single endoscopic stricture dilatation
3 endoscopic dilatations 3 weeks apart and possible needle knife strictureplasty

Eligibility
Inclusion criteria
* Inflammatory bowel disease patients with intestinal stricture(s) identified on CT, MRI or endoscopy.
Exclusion criteria
* Acute bowel obstruction requiring urgent surgical intervention * Deemed by treating physician to have high risk of acute bowel obstruction * Concurrent active perianal sepsis * Internal fistulising disease in association with strictures (entero-enteric stulas) * Low rectal or anal strictures * Evidence of dysplasia or malignancy from stricture biopsies or adjacent mucosal biopsies * Patients for whom endoscopy is not suitable due to co-morbidities or clinical state * Inability to give informed consent * Suspected perforation of the gastrointestinal tract * Pregnancy * Inability to undergo MRI small bowel due to a contraindication.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Improvement in obstructive symptoms using the Obstructive Symptom Score (OSS). | 6 months | The Obstructive Symptom Score (OSS) is a composite measure of the total number of days of obstructive abdominal pain and the severity over a fourteen-day period using a 5-point Likert scale. (no pain, mild, moderate, severe, unbearable) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Improvement in imaging parameters | 6 months | MRI and intestinal ultrasound |
| Improvement in endoscopic features | 6 months | Increased patency of strictures on endoscopy |
| Improvement in obstructive symptoms using the Obstructive Symptom Score (OSS). | 3, 6 and 12 months | The Obstructive Symptom Score (OSS) is a composite measure of the total number of days of obstructive abdominal pain and the severity over a fourteen-day period using a 5-point Likert scale. (no pain, mild, moderate, severe, unbearable) |
| Improvement in patient reported outcomes (PROs) | 6 months | IBDQ |
| Technical success of procedure | At time of procedure | Successful endoscopic procedure |
| Avoidance of surgery | 6 months | Requirement for surgical resection of stricture |
