Clinical Trial: A Study Comparing Transperineal Ultrasound, Magnetic Resonance Imaging, Endoscopic Ultrasound, and Examination Under Anesthesia to Detect and Classify Perianal Fistulas in Patients With Crohn's Disease or Fistulas of Unknown Cause

U.S., Sept. 1 -- ClinicalTrials.gov registry received information related to the study (NCT07794410) titled 'A Study Comparing Transperineal Ultrasound, Magnetic Resonance Imaging, Endoscopic Ultrasound, and Examination Under Anesthesia to Detect and Classify Perianal Fistulas in Patients With Crohn's Disease or Fistulas of Unknown Cause' on Aug. 03, 2025.

Brief Summary: The goal of this study is to learn how well different imaging tests detect and describe perianal fistulas in adults with Crohn's disease or fistulas with no known cause (cryptogenic). Perianal fistulas are painful tunnels that form near the anus and can lead to discharge, swelling, or infection. The main questions this study aims to answer are:
