Abstract

Abstract : Background: To investigate the value of double-balloon endoscopy(DBE), CT enterography (CTE) and their combination for the diagnosis of small bowel Crohn disease(CD). Methods: Data of 35 patients admitted from January 2018 to December 2019 who were clinically suspected of small bowel CD undergoing double-balloon endoscopy(DBE) were reviewed. 30 patients underwent CT enterography (CTE). Diagnosis was made based on pathological, endoscopic findings, CT enterography findings and clinic follow-up results. Detection rates and diagnosis rates of small bowel CD were compared by double-balloon enteroscopy(DBE) and CT enterography(CTE). Results: The detection and diagnosis rates of small bowel CD by double-balloon endoscopy (DBE) were 97.1%(34/35) and 91.2%(31/34), respectively. These two variables by CT enterography(CTE) were 86.7%(26/30) and 88.5%(23/26). Both double balloon enteroscopy (DBE) and CT enterography (CTE) detected small intestinal CD in 25 cases, with a detection rate of 83.3% (25/30) and a diagnosis rate of 92%(23/25). The detection rate and diagnosis rate of double balloon enteroscopy (DBE) were higher than that of CT enterography(CTE). Double balloon enteroscopy(DBE) combined with CT enterography(CTE) has the highest rate of diagnosis. Conclusions: Double balloon enteroscopy(DBE) has high application value for the diagnosis of small bowel CD, and can be recommended as the first choice for the diagnosis of small bowel CD. For those contraindicated with endoscopy, CT enterography(CTE) can be considered as a preferred auxiliary diagnostic modality. The combination of the two methods can complement each other and provide more information for the diagnosis of small bowel CD, thus improving the diagnosis rate of small intestinal CD.
