Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary specific aim is to perform a randomized controlled trial (RCT) to compare 30 day rebleed rates and other clinical outcomes of patients with severe, non-variceal upper GI hemorrhage (NVUGIH) - ulcers and Dieulafoy's lesions who are randomized as initial treatment with the new large over-the-scope-clip device for endoscopic hemostasis versus standard endoscopic hemostasis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Upper GI Hemorrhage (UGIH) causes significant morbidity and mortality, although endoscopic hemostasis has revolutionized management of these patients. Despite standard endoscopic treatment and high dose proton pump infusions, 25% - 30% of high risk patients with UGIB from ulcers or other non-variceal UGI lesions (NVUGI) had recurrent bleeding in a recent RCT and cohort studies by our group. Potential risk factors for NVUGI rebleeding were large ulcers (≥ 15 mm), fibrotic bases, Dieulafoy's lesions, anastomotic ulcers, coagulopathies, cirrhosis, other severe co-morbidities and residual arterial blood flow under stigmata of recent hemorrhage (SRH) after endoscopic treatment. Such patients with rebleeding after standard endoscopic hemostasis usually required angiography (by interventional radiologists-IR) or surgery for definitive hemostasis. A new, large, FDA approved, over-the-scope hemoclipping device (OTSC® System OVESCO Endoscopy, Tübingen, Germany) can capture larger amounts of tissue and underlying arteries than standard hemoclips and potentially can improve endoscopic hemostasis of such bleeding lesions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard endoscopic treatment

For those assigned to the standard endoscopy group, endoscopic hemostasis is performed using usual CURE hemostasis therapy for the focal GI lesions: injection of dilute (e.g. 1: 20,000) epinephrine (in 1-2 cc aliquots in 4 quadrants next to the SRH) of active bleeding or adherent clots (prior to snaring them off); coaptive coagulation with multipolar electrocautery (MPEC) probe and/or standard through the endoscope hemoclips along the course of the underlying artery as detected by DEP. Hemostasis is performed until active bleeding stops and/or the SRH is obliterated. Residual blood flow after visually guided hemostasis is recorded, but not used as a guide for additional hemostasis in this study.

Group Type OTHER

Standard endoscopic treatment

Intervention Type OTHER

Standard therapy includes injection of dilute epinephrine, thermal coagulation with multipolar electrocautery (MPEC) probe, and/or hemoclips.

Over-the-scope hemoclipping device

For those assigned OTSC, prior to use of the OTSC in UGI lesions with active bleeding or adherent clots, dilute epinephrine (1: 20,000) is injected around the SRH in 1-2 cc aliquots and the clots are cold guillotined off, as previously described (2, 4, 17). As a brief additional description, after initial diagnosis and preparation of the lesion and SRH (as described for standard hemostasis), the therapeutic sized endoscope is removed and this or a diagnostic panendoscope will be affixed with the OTSC of appropriate size for the endoscope and the target lesion. The endoscope is re-introduced and passed to the bleeding site. The SRH is centered in the field of view and within the cap of the OTSC device. Using high suctioning and firm pressure to center the SRH, the lesion and SRH is captured into the cap and the OTSC is deployed by rotating the handle and thereby compressing the bleeding lesion and surrounding tissue with mechanical hemostasis.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Written informed consent from the patient or a surrogate.
* Clinical evidence of severe UGIB.
* Presence of a benign appearing peptic ulcer, anastomotic ulcer, or Dieulafoy's lesion, with some SRH on endoscopy.
* Severe upper GI bleeding.
* Life expectancy of at least 30 days based on lack of severe or terminal comorbidity as judged by the generalist or subspecialist caring for the patient.

Exclusion Criteria

* Patients who are do-not-resuscitate (DNR) that is not reversible, uncooperative, refuse to participate, or are unable to give consent personally or through a legal surrogate.
* Active GI malignancy, under treatment but not in remission.
* Acute hypovolemic shock that is unresponsive to transfusion of 5 or more units of red blood cells (RBC's) or requires continuous intravenous vasopressor infusion for blood pressure support.
* ASA (American Society of Anesthesiology) class V or higher, moribund, or with a very poor prognosis and expected survival \<30 days.
* Severe coagulopathy or thrombocytopenia despite attempted reversal with transfusion of blood products (e.g persistent International Normalized Ratio \[INR\] \>2.0, platelet count \<20,000, a Partial Thromboplastin Time \[PTT\] greater than 2x upper limit of normal).
* Absolute contraindication to urgent endoscopy (such as suspected perforated viscus, or peritonitis).
* Stricture of the esophagus or pylorus that can not be dilated or precludes passage of a diagnostic sized endoscope and/or the GI endoscope with an 11, 3a OTSC device attached.
