Multidetector CT Enterography versus Double-Balloon Enteroscopy: Comparison of the Diagnostic Value for Patients with Suspected Small Bowel Diseases

الملخص EN

Aim.

To compare the diagnostic value of multidetector CT enterography (MDCTE) and double-balloon enteroscopy (DBE) for patients with suspected small bowel diseases.

Methods.

From January 2009 to January 2014, 190 patients with suspected small bowel diseases were examined with MDCTE and DBE.

The characteristics of the patients, detection rates, diagnostic yields, sensitivity, specificity, positive predictive value, and negative predictive value were described and analyzed.

Results.

The overall detection rates of DBE and MDCTE were 92.6% and 55.8%, respectively ( P <0.05 ), while the overall diagnostic yields were 83.2% and 33.7%, respectively ( P <0.05 ).

The sensitivity, specificity, positive predictive value, and negative predictive value of DBE were all higher than those of MDCTE.

DBE had a higher diagnostic yield for OGIB (87.3% versus 20.9%, P <0.05 ).

The diagnostic yields of DBE were higher than those of MDCTE for inflammatory diseases, angioma/angiodysplasia, and diverticulums, while being not for gastrointestinal tumors/polyps.

Conclusions.

The diagnostic value of DBE for small bowel diseases is better than that of MDCTE as a whole, but if gastrointestinal tumors are suspected, MDCTE is also needed to gain a comprehensive and accurate diagnosis.
