Background

Bowel ultrasound (US) represents a non-invasive, easily accessible cross-sectional imaging technique used increasingly to assess activity and complications of inflammatory bowel disease (IBD). It has a good sensitivity and specificity for detecting small and large bowel inflamed segments, as well as penetrating complications, in symptomatic patients, but its role in routine monitoring of asymptomatic IBD patients remains to be determined.

Therefore, the aim of this study was to assess the incidence of clinically relevant findings in asymptomatic IBD patients undergoing bowel US as a part of routine outpatient visit.

Methods

All consecutive IBD patients consulting one tertiary IBD centre with bowel ultrasound performed routinely at the outpatient visit where identified through insurance reporting system. In the period from July 2014 until March 2015, all US exams performed in IBD patients were identified and the US findings in asymptomatic patients were further analysed. Further investigations, such as endoscopy and magnetic resonance enterography indicated based on the ultrasound findings, were noted, as well as the ensuing change in the clinical management.

Results

From 248 consecutive US performed in the study period, 87 US (71 IBD patients; median age 30 years, range 19–70 years) were a part of a routine check of asymptomatic IBD patients (79% Crohn’s disease, 14% ulcerative colitis, and 7% IBD unclassified). In 38 out of these 87 examinations (44%), abnormalities were detected, and in 20 cases (53%), further investigations were performed, and therapy was changed in 16 patients (23% of all asymptomatic patients).

Conclusion

Routinely performed bowel US incorporated in routine follow-up revealed clinically relevant findings in up to one fourth of the asymptomatic IBD patients.
