The Use of Hexacapron in Upper Gastrointestinal Bleeding

The purpose of this study is to conduct a randomized control trial, double-blind study to compare Hexacapron with standard of care treatment to standard of care alone to evaluate the efficacy of adding effect of Hexacapron to standard therapy by decreasing the episodes of rebleeding and mortality in patient with upper gastrointestinal bleeding.

Research Objectives

To evaluate the efficacy of using hexacapron in treatment of upper gastrointestinal bleeding

* Primary outcome: Prevention of rebleeding manifested as hematemesis, melena and drop in hemoglobin level by 2g% within 24 hours after therapeutic endoscopy
* Secondary outcomes: rebleeding, need for surgery , 30 day mortality

Expected Significance- The sample size needed to detect a 10% absolute difference in the proportion of rebleeding, drop in hemoglobin by 2g% between the hexacapron treated group and standard of care group groups with 80% power and 0.05 significant levels(alpha).

Research methods:

* Prospective , randomized controlled trial , double blinded , single center
* Duration : 2 years
* \~ 300≤ participants ,18≤ years of age
* Patients 18≤ years of age admitted to emergency department in Shaare Zedek Medical Center with clinical signs and symptoms of upper gastrointestinal bleeding will receive initial resuscitation and stabilization maintaining blood pressure and intravascular volume.

Patients will be randomized to 3 groups:

1. Treatment group - receive I.V. Esomeprazole 80 mg once and then 8mg/h continuously with concurrent hexacapron I.V. every 6 hours until 72 hours and then the patient continue oral treatment 6 g /day for 7 days.
2. Standard of care group - receive I.V. Esomeprazole 80 mg once and then 8mg/h continuously

   * Every patient will undergo upper endoscopy within 12 hours of admission to emergency department and receive treatment according to the endoscopic findings
   * If no reason for bleeding will be found in upper endoscopy , treatment will be stopped and patient will be excluded
   * Every participant will fill a questionnaire with informed consent which will have to be signed.

     * If cannot sign due to his medical condition or disability his guardian will sign or first degree relative
