Trial Outcomes & Findings for Intestinal Ultrasound for the Evaluation of Pouchitis and Other Outcomes After Ileal Pouch-Anal Anastomosis (NCT NCT06316999)

NCT ID: NCT06316999

Last Updated: 2026-08-12

Results Overview

Radiologists were blinded to pouchoscopy with biopsy results and evaluated the intestinal ultrasound of the pouch for each patient; assessing whether normal healthy pouch or inflammation was present. Those results were then compared to gold standard of pouchoscopy with biopsies to confirm accuracy. The number (n(%)) of participants with abnormal ultrasound findings confirmed with gold standard are reported.

Participant Flow

protocol goal was to enroll 109, only 66 subject signed consent, and took part in the study.

Of the 66 subject that signed consent and had testing 11 subject ultrasound images not used for analysis, due to technique of preforming ultrasound.
