“…Our study showed no significant difference in PSV and EDV values between active and inactive CD, but we found a significant difference in RI values in mural arteries. Higher values of flow volume and lower RI of mural arteries in thickened bowel wall were recorded in different studies 22,24,25. The probable reason is arterial hyperemia in the thickened gut wall of Crohn’s disease.…”

Objectives:To investigate the diagnostic accuracy of ultrasound for evaluation of inflammatory activity in patients with Crohn’s disease (CD).Methods:Fifty-six patients with histologically proven CD (39 with active, 17 with inactive disease) and 30 healthy volunteers as a control group were enrolled in the study at WeiFang People’s Hospital, Weifang Province, China from October 2012 to December 2014. Bowel wall thickness, and vascularity pattern were measured by Doppler ultrasound.Results:There was a significant difference in flow volume of the superior mesenteric artery (585 ± 235 ml/min) in the patients with active disease, compared with those with inactive disease (401 ± 238 ml/min) and the control group (390 ± 189 ml/min, p<0.001). Wall thickness was 5.1 ± 1.5 mm in the active CD group, 3.3 ± 1.6 mm in the inactive disease group (p<0.001) and <3 mm in the control group. Resistance index in the thickened bowel wall showed some differences: 0.68 ± 0.05 in the active disease group, 0.78 ± 0.08 in the inactive disease group, and 0.85 ± 0.07 in the control group (p<0.05).Conclusion:Doppler ultrasound is a useful diagnostic tool in detecting CD and assessing inflammatory activity.

“…Vascularity within the bowel walls has been evaluated using a subjective scoring system according to the intensity of color signals and/or by the measurement of resistive index obtained from vessels detected within the bowel walls. [62][63][64][65][66][67][68] Ten studies including a total of 446 patients with established CD were identified 45,48,53,[55][56][57][58][59]61,62 (Table 6). All studies considered CDAI as reference standard and 3 studies used endoscopy as standard for disease activity.…”

“…A literature review revealed that CDUS examination of the SMA has been used to determine Crohn disease activity or intestinal inflammation caused by other illnesses, bowel wall perfusion in preterm neonates to predict developing necrotizing enterocolitis, or in children with small bowel obstruction for the detection of strangulation (8,14,15). In the present study we intended to evaluate SMA blood flow hemodynamics after surgery and found low values of SMA BFV, PSV, and RI when assessed with the cut-off values given in the literature (6)(7)(8).…”

Background/aim: The aim is to evaluate the long-term outcome of asymptomatic patients who underwent surgical correction for midgut volvulus. Materials and methods:Seven patients managed surgically for midgut volvulus in the last 3 years were included. Demographic features, symptoms at presentation, diagnoses, surgical procedures, and complications were recorded. Patients were then contacted for followup and evaluation of long-term outcomes. General physical conditions, anthropometric parameters, feeding habits, and defecation histories were evaluated. Laboratory examinations were performed. Color Doppler ultrasonography (CDUS) was performed to evaluate blood flow in the superior mesenteric artery (SMA).Results: In total, seven patients were identified. The median age at admission was 3 days (0-90 days). Mean age at follow-up was 17 ± 2 months. Growth parameters were normal in all cases. Four patients had low levels of ferritin and transferrin saturation. One patient had microcytic anemia. Another patient had low serum zinc level. One patient who had ileal resection had a high level of steatorrhea in stool examination. In CDUS, SMA blood flow volume was low in all cases. Peak-systolic velocity and resistance index were low in all but one case. Conclusion:Despite uneventful postoperative courses, all patients operated on for midgut volvulus showed mild laboratory changes and decreased blood flow in the SMA in long-term follow-up.
