Arm Label

Early Capsule Group

Standard of Care Work-up

Arm Description

The intervention for subjects in this arm will be to have a video capsule deployed as soon as possible after presentation to the clinical decision unit. Information from the video capsule will be obtained and reviewed to determine location of bleeding. Once that information has been obtained a decision will be made on which endoscopic test is most pertinent in finding and treating the source of bleeding.

In this arm, patients will receive "standard of care workup" for non-hematemesis gastrointestinal bleeding. This could include upper endoscopy, colonoscopy, and additional capsule or small bowel enteroscopy depending on the subject's presentation and the results of the workup performed by the gastroenterology team. For patients requiring a video capsule endoscopy as part of "standard of care workup" the patients will be given the same Olympus video capsule that is used in the "Early Capsule" group.

5. Study Description

Brief Summary
This study will evaluate the use of the Olympus EndoCapsule EC-10 video capsule compared with the standard of care workup for patients in the Clinical Decision Unit who have symptoms of gastrointestinal (GI) bleeding. Patients will be eligible if they have any symptoms of GI bleeding, either vomiting blood or symptoms without vomiting blood. Patients randomized to the early capsule arm will have an immediate video capsule endoscopy. Patients randomized to the standard of care arm will have no study intervention and will follow the treating physician's diagnostic workup. The primary goal of the study is to compare how often a source of bleeding is identified in patients in the two groups.
Detailed Description
After 40 years of considering gastrointestinal bleeding as upper or lower and largely ignoring the small intestine, there is accumulating evidence that the conventional approach to the assessment of non-hematemesis gastrointestinal bleeding (NHGIB) could be improved by early deployment of a video capsule as the first diagnostic test. Currently, video capsule endoscopy (VCE) is considered the gold standard diagnostic test for small intestinal bleeding after upper and lower endoscopy. However, video capsule endoscopy is an underutilized, minimally invasive tool that can improve rates of detection, minimize patient discomfort, and shorten the length of hospital stay for many patients. In a recent study at University of Massachusetts Worcester (UMass) of 336 patients who presented to the Emergency Department (ED) with complaints of gastrointestinal bleeding only 36 patients (10.7%) were given a video capsule during their stay.1 Traditionally, in patients with hematemesis (H), upper endoscopy has been the diagnostic and therapeutic modality of choice. However, recent data from a randomized clinical trial suggests that when video capsule endoscopy is used as the primary diagnostic tool, the investigators were able to safely define those patients that require admission from those that can be discharged for later follow-up 2. In this cohort, 30% of patients could be safely discharged and undergo endoscopy, if necessary within 48 hours, as an outpatient. This data is consistent with internal epidemiological data from UMass where nearly 30% of patients who were admitted did not receive any endoscopic evaluation as in-patients. Similarly, a randomized controlled trial has recently shown that patients with NHGIB may benefit from early VCE. In this population, the detection of active bleeding with video capsule as the first procedure was 63% compared with 27% for the standard of care approach. The study did not demonstrate a significant reduction in length stay since this was not part of the trial design. No attempt was made to change physician behavior. The study was too small to demonstrate a reduction in procedures, but there was a modest reduction in healthcare costs despite the addition of the video capsule. The study encountered no adverse events. Readmission rates were not significantly reduced but there were no re-admissions in the capsule group for gastrointestinal (GI) bleeding where there were four in the standard of care group. The hypothesis is that both signs and symptoms provide poor localization as to the origin of bleeding in NHGIB. Data from the previous study suggests that the ingestion of a video capsule in the emergency department could quickly and non-invasively provide clinicians accurate data as to the origin of the bleeding. This information could provide a guide to further management of the patient. Video capsule endoscopy is able to visualize bleeding in the esophagus, stomach, duodenum, small intestine and right colon, thereby eliminating the guess work of deciding which endoscopic approach to use. The study plans to use the clinical decision unit for two reasons. This unit provides an ideal site for the early safe deployment of a video capsule or initiation of a standard of care workup for either or NHGIB. Second, in those patients who are demonstrated not to be bleeding in either group by capsule endoscopy or standard of care workup may be discharged home safely without being admitted, thereby saving significant costs. It is known that 80% of patients stop bleeding spontaneously. Thus, the earlier they are examined the more likely the origin of the bleeding is likely to be found and appropriate management instituted. The use of capsule endoscopy has been approved by the FDA since 2001 for small intestinal bleeding obscure GI Bleeding. It is very safe, no deaths associated with its use have been reported. More than 3 million capsules have been deployed and obstruction and perforation are extremely rare. Interest in the broader use of VCE is accumulating. A pilot study on the use of early use of VCE in acute NHGIB showed a 50% reduction to time to diagnosis in 24 patients. More recently studies of VCE deployed in the ED, in patients with upper GI bleeding showed improved management. The UMass group recently demonstrated that the closer a video capsule is performed to the time of bleeding the higher the likelihood of locating the sources and the higher the therapeutic intervention rate. This protocol is logical step to prospectively examine this concept in a large randomized prospective trial for both H and NHGIB. The questions are, can early capsule intervention decrease time to diagnosis, numbers of procedures, admission rate and hospital length of stay in patients with H and NHGIB.
