Precise Endoscopic Application of Tranexamic Acid and Sucralfate in Gastrointestinal Bleeding: A Randomized Controlled Trial

Summary

Background and Aim: Gastrointestinal bleeding (GIB) is a common problem in the hospital. GIB can be divided into upper GIB, small bowel bleeding, and lower GIB. Endoscopic hemostasis includes epinephrine injection, hemoclipping, heat probe coagulation, and Argon plasma coagulation. Although the successful hemostasis rate is high, recurrent bleeding can occur, ranging from 10% to 50% according to the bleeding etiology. Therefore, how to reduce the rebleeding of GIB is an important clinical issue. Methods: This is a randomized clinical trial. Patients with gastrointestinal bleeding for endoscopy screening and treatment at National Cheng Kung University Hospital were enrolled. The study will recruit 60 patients. After randomization, 30 patients will be classified into the intervention group and 30 into the control group. The participants will receive standard endoscopic hemostasis by either local injection of diluted epinephrine, heater probe coagulation, hemoclipping, or band ligation. After then, we will spray 2g of sucralfate powder and 1g of tranexamic acid through duodenoscopy precisely on the bleeding site in the intervention group. All enrolled patients will be monitored for rebleeding for 28 days after the first endoscopy.
