Comparing the Accuracy of Different Ultrasound -based Scores to Assess Disease Severity in Patients with Inflammatory Bowel Disease

Brief Summary

Detailed Description

* Infammatory Bowel Disease (IBD) is a lifelong chronic disease comprised of two main entities: Crohn's disease and Ulcerative Colitis. The former can involve any part of the gastrointestinal tract with marked mural infammatory change and frequent complications related to either a penetrating or fbrostenotic phenotype, while the latter is a superfcial inflammatory process involving only the colon. IBD can undergo spontaneous periods of remission and activity and has a full spectrum from mild inconsequential disease to incapacitating complications, which may alter both lifestyle and longevity * IBD patients require repeat imaging throughout the course of their disease, necessitating a safe, noninvasive, available, and repeatable method. Imaging is required at diagnosis, routine surveillance, and acute flare of disease. Ultrasound imaging meets these demands with a high degree of accuracy and wide patient acceptance. Ultrasound provides high-resolution imaging and is excellent for detailed evaluation of the bowel wall and surrounding soft tissues performed without ionizing radiation with an extremely low risk of adverse contrast events compared to CT and MR Enterography which use ahigh dose of ionizing radiation, making it the frst choice of many Gastroenterologists and overwhelmingly preferred by patients Several established IUS parameters are assessed during an IUS examination. These include bowel wall thickness (BWT); the stratification of the bowel wall layers, blood flow, luminal diameters, and motility, Additional extraintestinal surrogates to bowel inflammation to assess for include mesenteric fat proliferation and lymphadenopathy ,with proposal of different sonographic scoring systems in this domain to predict disease severity
