Small intestinal vascular malformation bleeding: diagnosis by double-balloon enteroscopy combined with abdominal contrast-enhanced CT examination.

Aim: The purpose of this study was to explore the value of double-balloon enteroscopy combined with abdominal vascular-enhanced CT examination for the diagnosis of intestinal vascular malformation bleeding, to explore a simple and effective method for the diagnosis of small intestinal vascular malformation bleeding.

Methods: Ten patients with intestinal bleeding were first examined with double-balloon enteroscopy. If active bleeding considered as vascular malformation was observed, the patient underwent abdominal vascular-enhanced CT examination. If no active bleeding was observed with double-balloon enteroscopy, the patient also underwent abdominal vascular-enhanced CT examination. When intestinal vascular malformation bleeding was diagnosed with double-balloon enteroscopy and/or abdominal vascular-enhanced CT examination, the patient underwent surgical operation and vascular malformation was confirmed with pathologic diagnosis.

Results: In ten patients who underwent double-balloon enteroscopy examination, active intestinal bleeding was observed in seven patients and no active bleeding was observed in three patients. All ten patients underwent abdominal vascular-enhanced CT examination and vascular malformation was detected in all the patients with confirmation by pathologic diagnosis.

Conclusion: Double-balloon enteroscopy combined with abdominal vascular enhanced CT examination is a simple and effective method for the diagnosis of intestinal vascular malformation bleeding.
