P331 Development of a novel transabdominal ultrasound disease activity score in patients with ulcerative colitis (UCUS score)

BackgroundUlcerative colitis (UC) occurs in young patients and is characterised by remitting and relapsing episodes. Evaluation of the colorectal mucosa with colonoscopy (CS) is the gold standard technique for determination of treatment. However, CS can be burdensome to both patients and physicians. Transabdominal ultrasonography (TAUS) may become an alternative to CS because it is non-invasive, is well accepted by patients, and has excellent spatial resolution. This study was performed to identify the US parameters that can predict UC endoscopic activity and develop a simple US score.
