BACKGROUND & AIMS: The utility of ultrasound and color Doppler in the diagnosis and evaluation of inflammatory bowel diseases (IBD) has not been studied enough. Therefore, the aim of the current study was to evaluate the importance of conventional abdominal ultrasound and color Doppler in diagnosing IBD and assessing disease activity.
The study was conducted at the National Hepatology and Tropical Medicine Research Institute (NHTMRI) between July 2018 and January 2019, in which 150 patients were suffering from diarrhea, dysentery, tenesmus, or rectal bleeding were evaluated by colonoscopy, high-resolution ultrasound, and color Doppler scans.
The present study was conducted on 150 patients; 84 (56%) had ulcerative colitis (UC), 16 (10.7%) had Crohn's disease (CD), and 50 (33.3%) had normal colonoscopy results with a mean age 37.2 ± 9.059. The superior mesenteric Artery Peak Systolic Velocity (SMA-PSV) and End Diastolic Velocity (EDV) were significantly higher in both UC and CD than in the control group; however, pulsatility index (PI) was significantly higher in the control group than both UC and CD. However, there was no significant difference between UC and CD. The inferior mesenteric artery PSV and EDV were significantly higher in both UC and CD than in the control group.
Doppler ultrasound findings of SMA and IMA correlate with the incidence of inflammatory bowel disease, the site of disease, and its activity.
超声和彩色多普勒在炎症性肠病（IBD）的诊断和评估中的应用尚未得到充分研究。因此，本研究旨在评估常规腹部超声和彩色多普勒在诊断 IBD 和评估疾病活动中的重要性。
该研究于 2018 年 7 月至 2019 年 1 月在国家肝脏病学和热带医学研究所（NHTMRI）进行，其中 150 例腹泻、痢疾、里急后重或直肠出血的患者接受了结肠镜检查、高分辨率超声和彩色多普勒扫描。
本研究共纳入 150 例患者；84 例（56%）为溃疡性结肠炎（UC），16 例（10.7%）为克罗恩病（CD），50 例（33.3%）结肠镜检查结果正常，平均年龄为 37.2 ± 9.059 岁。UC 和 CD 患者的肠系膜上动脉峰值收缩速度（SMA-PSV）和舒张末期速度（EDV）均明显高于对照组；然而，搏动指数（PI）在对照组中明显高于 UC 和 CD。然而，UC 和 CD 之间没有显著差异。UC 和 CD 患者的肠系膜下动脉 PSV 和 EDV 均明显高于对照组。
SMA 和 IMA 的多普勒超声表现与炎症性肠病的发生率、病变部位及其活动度相关。
