简要总结

This study is designed as a controlled trial to evaluate the efficacy of balloon-assisted enteroscopy-guided radial incision therapy for the treatment of stricturing small bowel Crohn's disease. The study aims to compare therapeutic outcomes, procedure-related complications, and recurrence rates in patients with stricturing small bowel Crohn's disease undergoing balloon-assisted enteroscopy-guided radial incision therapy. The results are expected to provide a novel and reliable treatment option for patients with stricturing Crohn's disease and to lay a foundation for improving disease-related symptoms and quality of life.

入选标准

  • Age between 16 and 75 years.
  • Diagnosis of Crohn's disease with primary or secondary small bowel stricture confirmed by imaging studies, or small bowel stricture identified by enteroscopy.
  • Inadequate response to conventional medical therapy and step-up treatment strategies.
  • Stricture length less than 5 cm.
  • Signed informed consent form.

排除标准

  • Bowel wall thickening with Limberg grade IV blood flow on intestinal ultrasound, or presence of complications such as perforation, fistula, deep ulcer, inflammatory mass, or abscess.
  • Deep ulcer in the stricture segment observed by enteroscopy, potentially involving the muscular layer.
  • Presence of strictures in the esophagus, stomach, or duodenum.
  • Presence of colorectal stricture or ileocecal valve stricture.
  • Small bowel stricture complicated by abscess, fistula, or severe angulation.
  • Patients with ≥3 small bowel strictures or stricture length ≥5 cm.
  • Strictures previously treated with stent placement, dilation, or incision but without sustained symptom-free remission for at least 1 year.
  • Pregnancy or breastfeeding.
  • Inability to undergo endoscopic treatment.
  • Severe coagulation disorders (platelet count <70,000/μL, INR >1.5).
  • Concomitant advanced tumors or other severe organ diseases.
  • Suspected localized intestinal malignancy.

研究组 & 干预措施

No Intervention

Sham Comparator

Patients in this arm will not receive endoscopic interventional treatment for small bowel strictures and will be managed with standard medical therapy and clinical observation.

干预措施: No Interventions (Procedure)

Balloon-assisted enteroscopy-guided balloon dilation

Experimental

Patients in this arm will undergo balloon dilation of small bowel strictures under balloon-assisted enteroscopy to relieve luminal narrowing.

干预措施: balloon dilation (Procedure)

Balloon-assisted enteroscopy-guided stricture incision

Experimental

Patients in this arm will receive balloon-assisted enteroscopy-guided radial incision of small bowel strictures under direct endoscopic visualization.

干预措施: stricture incision (Procedure)

结局指标

主要结局

Proportion of patients not requiring additional therapeutic interventions at 1-year follow-up

时间窗: 1 year

Percentage of patients who do not require any new therapeutic intervention, including endoscopic balloon dilation (EBD), endoscopic stricture incision (EST), or surgery, within 1 year after the initial procedure.

次要结局

  • Immediate technical success of the procedure(At the time of procedure)
  • Symptom-free duration within 1 year post-procedure(1 year)
  • Proportion of patients not requiring additional therapeutic interventions at 3-year follow-up(3 years)
  • Proportion of patients not requiring additional therapeutic interventions at 5-year follow-up(5 years)
  • Safety assessment of the two treatment methods(Within 2 months post-procedure)
  • Cost analysis of the two treatment methods(Up to 1 year post-procedure)
