Small bowel tuberculosis diagnosed by the combination of video capsule endoscopy and double balloon enteroscopy.

Small bowel tuberculosis is sometimes encountered in oriental countries, and because its symptoms are vague and present a nonspecific pattern, confirmative diagnosis is difficult to achieve. In 2001, two new innovative endoscopic techniques for the small bowel, video capsule endoscopy and double balloon enteroscopy, were introduced, thus advancing the diagnostic technology for small bowel disorders. Our asymptomatic patient with small bowel tuberculosis was diagnosed definitively using the combination of video capsule endoscopy and double balloon enteroscopy. The number of such cases will increase when those procedures become more widely used. At present, the endoscopic view of small bowel tuberculosis is difficult to differentiate from Crohn's disease and drug-induced enteropathy, but from now on it will be possible to distinguish them utilizing endoscopic and fluoroscopic images. On the basis of the characteristics of small bowel tuberculosis with its endoscopic images, referring to our case report and previous literature, we report a topical diagnostic procedure, the combination of video capsule endoscopy and double balloon enteroscopy.
