Abstract
Background: Ulcerative colitis, a type of inflammatory bowel disease that merely affects the mucosa and submucosa of colon in the form of inflammatory ulcers. Objectives: Our study aimed to provide an extensive overview of the main pathologic features of gut wall vessels and bowel wall thickness at US examination of UC. Patients and Methods: This prospective case control study was done on 40 patients confirmed to have UC attending to Outpatient Clinics of Internal Medicine and Gastroenterology Department – Ain-Shams University from October 2018 to Augost 2019.. Results: The peak incidence of affected patients was 30–40 years of age. Female predominance compared to male with a ratio of 2.6:1. 20% of remission patients complaining from 1-2 bowel movement while 45% and 50% of relapsing patients suffer from 3-4 and 5 bowel movement respectively. 100%, 100%, 20% and 15% of relapsing patients suffer from bleeding per rectum, abdominal pain, tenesmus and urgency. Higher ESR and CRP and lower hemoglobin in relapsing compared to remission group. Furthermore, The last group has higher value of ESR and CRP and lower value of hemoglobin compared to control group. BWT was significantly thicker in relapse group (4.8±0.7 mm) than of remission (3.55±0.5 mm) compared to control group (1.6±0.5) (p value <0.001). BWT at a cut-offs > 4 mm discriminating between cases with relapse from those with remission and at a cut-offs >4 mm discriminating between mild endoscopic severity from moderate and severe UC. Furthermore, BWT at a cut-offs >4.6 mm discriminating between mild and moderate endoscopic severity from severe UC. Vascular signal number at a cut-offs >1 discriminating between cases with relapse from those with remission and at a cut-offs >2 discriminating between mild and moderate endoscopic severity of UC.
Conclusion: Abdominal ultrasound is a widely available non-invasive method for imaging of UC. It provides a high sensitivity, specificity and accuracy in diagnosis and monitoring of UC activity.
