Abstract

AIM: To evaluate the hemostatic effect of topical hemocoagulase spray in digestive endoscopy.

METHODS: Eighty-nine patients who developed oozing bleeding during endoscopic treatment from September 2014 to October 2014 at Center for Digestive Endoscopy, Tianjin Medical University General Hospital were randomly divided into either a study group (n = 39) or a control group (n = 50). The study group was given topical hemocoagulase spray intraoperatively, while the control group was given traditional 8% norepinephrine spray. Hemostatic efficacy was compared between the two groups. Bleeding site, wound cleanliness and perforation were recorded, and the rates of perforation and late bleeding were compared.

RESULTS: Successful hemostasis was achieved in 39 (100%) patients of the study group and in 47 (94.0%) patients of the control group, and there was no significant difference in the rate of successful hemostasis between the two groups. Compared with the control group, after topical hemocoagulase spray in the study group, the surgical field was clearer, the bleeding site was more easily identified, and the wound was cleaner. There was no significant difference in the rate of perforation between the study and control groups (16.7% vs 35.0%, P = 0.477), but the rates of late bleeding (0% vs 15.8%, P = 0.048) and overall complications (P = 0.032) were significantly lower in the study group.

CONCLUSION: Topical hemocoagulase spray has a definite hemostatic effect for oozing bleeding in digestive endoscopy, and this method is convenient, safe, and reliable. It is expected to become a new method for endoscopic hemostasis.

Core tip: In this study, we evaluated the hemostatic effect of topical hemocoagulase spray in digestive endoscopy. There was no significant difference in the rate of perforation between the study and control groups. There was no significant difference in the rate of successful hemostasis between the two groups, but the rates of late bleeding and overall complications of the hemocoagulase group were significantly lower than the 8% norepinephrine group. The surgical field was clearer, the bleeding site was more easily identified, and the wound was cleaner in the study group.
