Capsule Endoscopy Versus Conservative Therapy for Obscure Gastrointestinal Bleeding

Withdrawn before enrolling · Not applicable

Conditions studied: Hemorrhage, Anemia

In brief

This study is a single center prospective randomized control trial comparing the utility of performing capsule endoscopy compared to conservative management with oral iron therapy as the initial course of action in patients with non-severe obscure occult or obscure overt gastrointestinal (GI) bleeding. The investigators hypothesize that outcomes in patients with non-severe obscure GI bleeding who receive conservative therapy with oral iron will not differ to those on oral iron who undergo capsule endoscopy.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Adult men and post-menopausal women with iron deficiency anemia and pre-menopausal women with iron deficiency anemia and a negative gynecologic workup or adults with overt GI bleeding as defined by melena or hematochezia with a ≥2 gram drop in hemoglobin after stabilization (Iron deficiency is defined as hemoglobin <13.7 g/dL in men and <12 g/dL in women with serum ferritin level <50 ng/mL). Also, patients with an otherwise unexplained drop in hemoglobin of ≥ 2 g/dL in the setting of hemoccult positive stool
• Negative EGD and colonoscopy for source of GI bleeding within six months of enrollment into the study.

You may not qualify if…

• Ongoing overt gastrointestinal bleeding requiring ≥4 units of packed RBC's on any given day in the setting of overt bleeding, blood transfusions on separate days (separated by ≥12 hours), or ≥6 units of packed RBC's over the previous 7-day period prior to presentation, in the setting of overt bleeding.
• Myocardial infarct, acute neurologic event, sepsis, or respiratory failure within the previous 1 week
• History of small bowel obstruction
• Pregnant women
• Prisoners
• Age less than 18
• Known GI or hematologic malignancy
• Achalasia
• Contraindications to capsule endoscopy (inability to take prep), or felt unsafe to undergo capsule as per study investigators
• Esophageal stricture that precludes even endoscopic capsule placement
• History of upper GI or small bowel surgery
• Inability to take oral iron.
• Active IV iron use.
• Alternate source of blood loss (e.g., menorrhagia)
• Hematemesis sufficient to be the cause of the hemoglobin decline
