Endoscopic Collagen Spray A Novel Method Which can be Used as an Adjunct to Conventional Hemostatic Techniques in Peptic Ulcer Bleeding

Abstract

Aim: To study endoscopic collagen spray as a hemostatic agent in peptic ulcer bleeding not controlled by conventional therapy. Methods: In this prospective study, endoscopic collagen spray, VGM’s Haemoseal spray has been used in the treatment of peptic ulcer bleeding, as a single agent or in combination with other agents. Haemoseal Spray Kit consists of air pump, Haemoseal probe, a 7.5 Fr spray catheter, 230 cm in length and a pre-loaded collagen cartridge that contains 5 grams of powder. A maximum of 2 grams is applied depending on the area to be covered. Results: Eighteen consecutive patients, who presented with peptic ulcer bleeding were included. There were sixteen patients with duodenal ulcer and two patients with gastric ulcer. The hemorrhagic ulcers were Forrest classification category Ib in sixteen patients and Ia in two patients. After spraying collagen, the bleeding stopped within seconds in all the patients. Repeat endoscopy after 48 hours showed no rebleeding. One patient had an arterial spurt from duodenal ulcer. Collagen spray was used initially as there was poor visibility. After 24 hours, repeat endoscopy revealed visible vessel with no bleeding. Hemoclipping could be achieved. There were no side effects experienced by the patients. Conclusion: Collagen spray is a safe and effective endoscopic hemostatic agent in treatment of peptic ulcer bleeding not controlled by conventional therapy.
