Brief Summary:
Overt obscure gastrointestinal bleeding (OGIB) is a distinct clinical entity with significantly worse outcomes compared with colonic bleeding and upper GI bleeding. The mortality rate for patients with acute small bowel bleeding was 10%.1 Recently, a meta-analysis of 10 studies showed that VCE and DBE have an equivalent diagnosis yields in patients with obscure GIB (62% for VCE and 56% for DBE).2 The limitation of this meta-analysis study was that the included studies examined patients with occult OGIB and overt OGIB. Comparing with occult OGIB, patients with overt OGIB are more likely to present a significant lesion that causes a recurrent bleeding which subsequently increases risk of morbidity and mortality.3 According to emergency endoscopy concept from upper and lower GIB, patients with overt OGIB have been demonstrated the usefulness of urgent VCE and urgent DBE in a diagnosis tool with an impact on clinical management.4-7 Although previous studies showed promising data about the use of urgent enteroscopy, the debate about using VCE or DBE first in patients with massive overt OGIB is still uncertain. Thus in this study, we conducted the prospective study to compare urgent VCE with urgent DBE in patients with massive overt OGIB.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The consecutive patients with massive overt OGIB defined as a visible gastrointestinal bleeding (GIB) (eg, melena or hemotochezia) of unknown origin that persists after an initial negative esophagogastroduodenoscopy (EGD) and colonoscopy were recruited. Massive was defined as the need for at least 3 units of blood transfusion. All patients underwent an EGD and colonoscopy within the first 48 hrs of hospitalization.

Exclusion Criteria:

  • Exclusion Criteria pregnancy, patients with a suspected intestinal obstruction or stricture, cardiac pacemaker implantation or other electromedical device implantation, diabetic gastroparesis, a history of gastrectomy and small bowel surgery.
