Clinical Study on the Distribution of Digestive Tract Microbiota Before and After Ileocecal Resection in Crohn’s Disease
Overview
In this study, the microbiota sequencing was used to investigate the changes of microbiota in the terminal ileum and the middle part of ascending colon, the mesenteric adipose tissue of ileum and ascending mesocolon, and oral cavity of patients with Crohn's disease before and after ileocecal resection, so as to further explore the role of ileocecal region in inducing remission of disease.
Full Title of Study: “Clinical Study on the Distribution of Digestive Tract Microbiota Before and After Ileocecal Resection in Crohn’s Disease”
Study Type
- Study Type: Observational
- Study Design
- Time Perspective: Prospective
- Study Primary Completion Date: March 15, 2023
Arms, Groups and Cohorts
- Before ileocecal resection
- Patients diagnosed with Crohn’s disease after comprehensive evaluation of clinical symptoms, endoscopic features, radiological manifestations and histological features were recruited,and the patients were admitted for right hemicolectomy
- After ileocecal resection
- Patients diagnosed with Crohn’s disease after comprehensive evaluation of clinical symptoms, endoscopic features, radiological manifestations and histological features were recruited,and the patients underwent reversal of ileostoma after right hemicolectomy
Clinical Trial Outcome Measures
