NCT ID: NCT05387031 Recruiting - Crohn Disease Clinical Trials

Efficacy of Ustekinumab-based Integrated Medicine Therapy in Patients With Symptomatic Stricturing Crohn's Disease

Start date: May 26, 2022
Phase:
Study type: Observational

This study intends to select patients with confirmed moderate-to-severe Crohn's disease (CD) and obstructive symptoms of intestinal stenosis, who have clear evidence of lumen stenosis caused by the disease itself through radiography or endoscopy. After the informed consent of the patients, comprehensive drug therapy with ustekinumab as the mainstay was performed. The basic information and medical history of the patients were collected, and the treatment process of the patients was followed up and recorded, and the drug regimen was adjusted according to the physician's experience and judgment. At different follow-up time points, blood, feces, tissue and other specimens of patients were collected according to the situation, and gastrointestinal endoscopy, imaging examination, laboratory index examination, self-assessment of subjects' symptoms, and nutritional risk screening were performed on the patients. This study evaluated the CD disease activity, obstructive symptoms, and radiographic or endoscopic remission in patients at different follow-up time points, and comprehensively evaluated the efficacy of ustekinumab in relieving stenotic CD and its related factors.

Endoscopic Stricturotomy Versus Endoscopic Balloon Dilatation in Patients With Crohn's Disease and Symptomatic Small Bowel Stricture

DESTRESS
Start date: August 1, 2021
Phase: N/A
Study type: Interventional

Stenosis is one of the most frequent complications in patients with Crohn's disease (CD). In particular, CD patients with intestinal strictures are often faced with short bowel syndrome after repeated or extensive surgical resection. Endoscopic management shows good efficacy and safety in the treatment of strictures in CD patients. The European Crohn's and Colitis Organisation (ECCO) guideline recommended that endoscopic balloon dilatation is suitable to treat short [<5 cm] strictures of the terminal ileum in CD. Recently, Lan et al. reported that endoscopic stricturotomy appeared to be more effective in treating CD patients with anastomotic stricture than endoscopic balloon dilatation. However, there is no prospective clinical studies evaluating the efficacy and safety of endoscopic stricturotomy in the treatment of fibrostenotic Crohn's disease. The trial aims to compare the efficacy and safety of endoscopic stricturotomy with endoscopic balloon dilation in the treatment of small bowel stricture in patients with Crohn's Disease.

NCT ID: NCT04865484 Recruiting - Crohn Disease Clinical Trials

Prospective Randomized Comparative Study of the Treatment of Multisegmental Fibrostenosing Crohn's Disease.

SUREST
Start date: March 12, 2021
Phase: N/A
Study type: Interventional

Stenosis is one of the most frequent complications in patients with Crohn's disease (CD). In particular, CD patients with multi segmental intestinal strictures are often faced with short bowel syndrome after repeated or extensive surgical resection. Strictureplasty conserves bowel and minimizes the risk of developing short-bowel syndrome in the short-term and, probably, long-term. Strictureplasty has become an established surgical option in the management of obstructive Crohn's disease, especially for multiple short fibrous strictures. It is particularly suitable for patients at risk for short-bowel syndrome. Endoscopic management shows good efficacy and safety in the treatment of strictures in CD patients. The ECCO guideline recommended that endoscopic balloon dilatation is suitable to treat short [<5 cm] strictures of the terminal ileum in CD. Recently, Lan et al. reported that endoscopic stricturotomy appeared to be more effective in treating CD patients with anastomotic stricture than endoscopic balloon dilatation. However, there is no scientific evidence for determining the most appropriate treatment for multiple fibrosis stenosis. We designed a prospective randomized comparative study of the treatment of multisegmental fibrostenosing Crohn's disease (surgical resection plus endoscopic stricturotomy versus surgical resection plus strictureplasty).

Stricture Definition and Treatment (STRIDENT) Endoscopic Therapy Study

STRIDENT
Start date: October 9, 2017
Phase: N/A
Study type: Interventional

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.
