“…Superior mesenteric artery diameter increases with a number of stimuli, including meal [37,76,90] and decreases with exercise [77], cold stimuli [81] and hypovolaemia [74]. Also SMA diameter increases in diseases with enteric manifestation [24], including Crohn's colitis [54,70] and celiac disease [1]. Major clinical importance of SMA diameter and flow is during evaluation of chronic mesenteric ischaemia.…”

“…Flow measurements of the superior and inferior mesenteric arteries by Doppler ultrasound have been reported as an additional tool to measure disease activity in patients with Crohn's disease [25][26][27]. This method is complicated by angle dependence of the Doppler shift, high deviations of flow measurements and a high interequipment variability [28].…”

Background/Aim: In recent years, power Doppler sonography has been proposed as a method to assess disease activity in patients with Crohn’s disease. The aim of this prospective study was to evaluate diagnostic criteria for power Doppler sonography by blinded comparison with ileocolonoscopy. Methods: Twenty-two patients with confirmed Crohn’s disease were prospectively investigated with B-mode and power Doppler sonography (HDI 5000, Philips Ultrasound) as well as ileocolonoscopy. Sonography was performed within 3 days before endoscopy. All procedures were performed by experienced examiners who were blinded to the clinical data and other results. Defined ultrasound parameters (bowel wall thickness, vascularization pattern) were used to determine a sonographic score of the activity. The degree of activity was scored from 1 (none) to 4 (high) by both ultrasound and ileocolonoscopy (pattern, extent of typical lesions). For each patient all segments of the colon and the terminal ileum were evaluated by both ultrasound and endoscopy. The weighted ĸ test was used (StatXact software) for statistical analysis. Results: In total, 126 bowel segments were evaluated by both ultrasound and endoscopy. The study showed a high concordance of power Doppler sonography and ileocolonoscopy (weighted ĸ by region: sigmoid colon: 0.81; transverse colon: 0.78; ascending colon: 0.75; cecum: 0.84; terminal ileum: 0.82). Highest concordance was found in the descending colon (weighted ĸ: 0.91; 95% CI: 0.83–0.98). Conclusions: Combination of B-mode and power Doppler sonography has a high accuracy in the determination of disease activity in Crohn’s disease when compared to ileocolonoscopy. The diagnostic criteria established in this study can be useful for the evaluation of inflammatory bowel diseases by ultrasound.

Activity of Crohn disease assessed by measurement of superior mesenteric artery flow with Doppler US.

Abstract: Activity of Crohn disease causes a substantial increase in SMA flow volume. Measurement of SMA blood flow may be an important noninvasive, readily available, inexpensive tool that can be used to monitor Crohn disease objectively.
