Official title
Clinical Study on the Integration of Traditional Chinese Medicine Xu Gua Therapy With Mesenchymal Stem Cells for the Treatment of Crohn's Disease-Associated Anal Fistula.
Overview
To evaluate the efficacy and safety of TCM virtual hanging therapy combined with mesenchymal stem cellsin the treatment of CD anal fistula. To establish the standard of clinical diagnosis and treatment and thestandard procedure of operation for the treatment of CD anal fistula by virtual hanging therapy combinedwith mesenchymal stem cells.
Interventions
- Procedure TCM dummy therapy combined with mesenchymal stem cell injection therapy
Combines TCM dummy therapy with mesenchymal stem cell injection, integrating traditional local stimulation and modern stem cell regenerative mechanisms. - Procedure Dummy Line Therapy Group
Utilizes traditional thread-embedding techniques, placing specialized threads at specific sites to effectively drain inflammatory exudates and necrotic materials. - Procedure MSC Group
Administers mesenchymal stem cell injections directly to target areas, leveraging their differentiation and anti-inflammatory properties to enhance tissue repair.

Eligibility criteria
Inclusion criteria
Signed informed consent form.
Diagnosis of Crohn's disease (CD) confirmed at least 6 months prior to screening, based on the Chinese Consensus on Diagnosis and Treatment of Inflammatory Bowel Disease (2018, Beijing).

Good general health status confirmed by medical history and relevant examinations.
Exclusion criteria
CDAI >220 or requiring immediate treatment for active CD.
Patients with rectal/anal stenosis or active proctitis (due to procedural limitations).
