Clinical Trial 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.

Description:

Prospective randomised controlled study. Patients with Crohn's Disease and symptomatic stricture(s) will undergo randomisation to receive standard or intensive endoscopic therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Improvement in obstructive symptoms using the Obstructive Symptom Score (OSS).	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)	6 months
Secondary	Improvement in obstructive symptoms using the Obstructive Symptom Score (OSS).	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)	3, 6 and 12 months
Secondary	Improvement in imaging parameters	MRI and intestinal ultrasound	6 months
Secondary	Improvement in endoscopic features	Increased patency of strictures on endoscopy	6 months
Secondary	Avoidance of surgery	Requirement for surgical resection of stricture	6 months
Secondary	Improvement in patient reported outcomes (PROs)	IBDQ	6 months
Secondary	Improvement in patient reported outcomes (PROs)	SF36	6 months
Secondary	Technical success of procedure	Successful endoscopic procedure	At time of procedure
