Diagnosis of Inflammatory Bowel Disease by Abdominal ultrasound and Color Doppler Techniques
Background &Aims: The utility of ultrasound and color Doppler in diagnosis and assessment of the activity of
inflammatory bowel diseases (IBD) is not studied enough. So, the aim of the current study was to evaluate the value of
conventional abdominal ultrasound and color Doppler in the diagnosis of IBD and assessing disease activity.
Methods: The study was conducted in National Hepatology and Tropical Medicine Research institute (NHTMRI) in the
period between July, 2018 and January, 2019; where 150 patients suffering from diarrhea, dysentery, tenesmus or
bleeding per rectum were evaluated by colonoscopy, high resolution ultrasonography and color Doppler scanning.
Results: The present study was conducted on 150 patients, where 84 (56%) had Ulcerative colitis (UC) disease, 16
(10.7%) were Crohn's disease (CD) and 50 (33.3%) had normal colonosopic findings with their mean age was
(37.2±9.059). The superior mesenteric artery (SMA) peak systolic velocity (PSV) and end diastolic velocity (EDV) was
significantly higher in both UC and CD than 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 (IMA) PSV and EDV was significantly higher in both UC and CD than the control group.
Conclusions: Doppler sonographic findings of SMA and IMA correlate with the incidence of IBD and their site of
affection and their activity.
