A Pilot and Feasibility Study to Evaluate Capsule Endoscopy (MA-79)
|ClinicalTrials.gov Identifier: NCT00974701|
Recruitment Status : Completed
First Posted : September 10, 2009
Last Update Posted : June 10, 2011
This study is aimed at assessing the capability of the PillCam Platform using the PillCam ESO 2 Capsule in:
- Determining whether there is 1) active bleeding in the Upper gastrointestinal (UGI) tract, 2) identifying the anatomic location of acute overt UGI bleeding, and 3) discriminating a variceal versus non-variceal source of UGI bleeding.
|Condition or disease||Intervention/treatment|
|Upper Gastrointestinal Hemorrhage||Device: PillCam ESO2|
Upper gastrointestinal hemorrhage (UGIH) is a prevalent, clinically significant, and expensive healthcare problem worldwide. The incidence of acute, overt UGIH has been estimated to be 50-150 cases per 100,000 adults in the United States population each year.
Clinical Significance / Rationale EGD is the currently accepted community standard for the diagnosis and management of UGIH. Diagnostic EGD in persons presenting with acute UGIH allows for (1) differentiating the source of bleeding (variceal vs. non-variceal), (2) defining the anatomic location of the bleeding site (e.g., esophagus, stomach, duodenum), (3) providing an endoscopic diagnosis, and (4) facilitating patient triage for subsequent level of care (ICU, monitored bed, non-monitored bed, early / expedited hospital discharge).
Capsule endoscopy for the small bowel was cleared by the FDA in 2001, and within a short time, has gained acceptance as providing state-of-the-art endoscopic imaging. Capsule endoscopy is now commonly used in the evaluation of patients with obscure gastrointestinal bleeding, including iron deficiency anemia, suspected and known Crohn's disease, malabsorption syndromes (e.g., Celiac disease), and chronic abdominal pain. Capsule endoscopy technology is now also being applied to evaluation of the esophagus (PillCam® ESO, Given Imaging, Ltd, Yoqneam, Israel) and the colon (PillCam® COLON). Recently, a second generation esophageal capsule endoscope (PillCam® ESO 2, Given Imaging Ltd, Yoqneam, Israel) was cleared by the United States Food and Drug Administration in June 2007. While having the same outer dimensions (length and diameter) as the original PillCam ESO capsule, several significant improvements have been made to the internal components of the PillCam ESO 2. Similar to the original PillCam ESO, the system includes a sensor array and data recording device which are connected to the patient during the procedure. The recorded data is downloaded into the Given Imaging RAPID® workstation for review of the capsule endoscopy video.
However, there are no published detailed data evaluating the feasibility of utilizing PillCam ESO 2 in individuals presenting with acute, overt UGI bleeding. Moreover, there are no data comparing PillCam ESO 2 and EGD in the evaluation of this patient population. Therefore, in this proof-of-concept pilot study, we will evaluate the feasibility and safety of using PillCam ESO 2 in individuals presenting with acute, overt UGI bleeding.

The capsule to be tested in this proposed study, PillCam ESO 2 capsule Endoscopy, is an improved version with exactly the same dimensions as the current PillCam ESO capsule, both in length and diameter.
Other Name: PillCam ESO 2
- Identification of gross blood (fresh or coffee grounds) / active bleeding in the esophagus, stomach and /or duodenum by PillCam™ ESO 2 and NG aspirate [ Time Frame: 7 days ]
- Suspected anatomic location of acute overt UGI bleeding (e.g., esophageal, gastric, and/or duodenal location) by PillCam™ ESO 2 and EGD. [ Time Frame: 7 days ]
- Determination of suspected variceal vs. non-variceal source of acute overt UGIH by PillCam™ ESO 2 and EGD. [ Time Frame: 7 days ]
- Number, type and severity of adverse events and number of PillCam™ ESO 2 capsules that reached the 2nd portion of the duodenum. [ Time Frame: 7 days ]
- Patient subjective assessment questionnaires [ Time Frame: 7 days ]
