Comparative Analysis of Hemostatic Efficacy: Local Application of Lancehead Snake Venom Thrombin versus Hemostatic Forceps in Colon Polypectomy.

Background • Colon polypectomy often involves managing bleeding, and the choice of hemostatic methods is critical for patient outcomes. This study addresses the hemostatic effects of lancehead snake venom thrombin compared to hemostatic forceps in the context of colon polypectomy. Objective • To compare and assess the effectiveness and safety of local application of lancehead snake venom thrombin and hemostatic forceps in achieving hemostasis during colon polypectomy. Design • A randomized controlled trial was conducted to investigate and compare the hemostatic outcomes of two different approaches in colon polypectomy. Setting • The study was conducted at the Affiliated Hospital of Hebei University Hospital from January 2022 to June 2022. Participants • A total of 80 patients with colon polyps who met the inclusion criteria were randomly assigned to either the lancehead snake venom thrombin group or the hemostatic forceps group. Interventions • In the hemostatic forceps group, hemostatic forceps were employed to seal the wound postpolyp resection. In the lancehead snake venom thrombin group, aluminium potassium sulfate gel, in conjunction with locally sprayed lancehead snake venom thrombin, was applied to the wound. Primary Outcome Measures • The study assessed (1) intraoperative immediate bleeding and hemostasis; (2) intraoperative hemostasis time; (3) postoperative delayed post-polypectomy bleeding (DPPB); and (4) adverse reactions as primary outcome measures. Results • No significant differences were observed in the incidence rate of intraoperative immediate bleeding and the success rate of intraoperative hemostasis between the two groups. The lancehead snake venom thrombin group exhibited a shorter intraoperative hemostasis time and a lower incidence rate of adverse reactions compared to the hemostatic forceps group. No significant difference was found in the incidence rate of postoperative DPPB between the two groups. Conclusion • Local application of lancehead snake venom thrombin proves to be more effective and safer than hemostatic forceps in promptly managing bleeding during colon polypectomy.
