Effect of High-dose Oral Rabeprazole on Recurrent Bleeding After the Endoscopic Treatment of Bleeding Peptic Ulcers

Peptic Ulcer Hemorrhage Clinical Trial

Official title: Effect of High-dose Oral Rabeprazole on Recurrent Bleeding After the Endoscopic Treatment of Bleeding Peptic Ulcers

Status Terminated

Clinical Trial Summary

This study is conducted to compare and evaluate the effect of administering a high-dose intravenous proton pump inhibitors or high-dose oral Rabeprazole in preventing recurrent bleeding after the endoscopic treatment of bleeding peptic ulcers.

Clinical Trial Description

0.1 % of hospitalized patients are attributed to upper gastrointestinal bleeding every year in the U.S. and Europe, among which peptic ulcer is the most common cause of upper gastrointestinal bleeding. Endoscopic hemostasis procedure in the management of bleeding due to peptic ulcers was safe as well as effective and lowered recurrent bleeding, surgery and mortality. Endoscopic treatment is widely used as an effective and safe method but it has disadvantages including the need for the endoscopy specialist and the likelihood of developing the complications such as perforation or recurrent bleeding although they rarely occur. Thus, less invasive medical treatments with fewer side effects have been continuously studied and among them, gastric acid inhibitors have been studied the most.Acid and pepsin inhibit platelet aggregation, activation of blood coagulation system, and fibrinogen polymerization. Blood clots already formed are digested by pepsin and the activity of pepsin is closely related to intragastric pH level. Therefore, it is known that an elevated intragastric pH facilitates hemostasis process, induces hemostasis by stabilizing hematoma and prevents recurrent bleeding. To suffice these conditions, it is reported that a potent gastric acid inhibitor is needed to maintain intragastric pH of 6 or higher.

For the treatment of bleeding peptic ulcers, the intravenous administration of a high-dose proton pump inhibitor after the initial endoscopic treatment has shown a decline in the frequency of recurrent bleeding as well as surgery. Recent studies reported that the use of oral proton pump inhibitor was effective under certain circumstances in the treatment of bleeding peptic ulcers. However, to date, no study has been conducted to compare the effect of a high-dose intravenous proton pump inhibitor with that of oral Rabeprazole after endoscopic treatment of bleeding peptic ulcers. Therefore, in this study, after administering a high-dose intravenous proton pump inhibitor or high-dose oral Rabeprazole in preventing recurrent bleeding following endoscopic treatment of bleeding peptic ulcers, we are going to compare the rate of recurrent bleeding between the two groups as well as to compare and evaluate the surgery rate, mortality rate and the number of days of hospital stay. ;
