Endoscopic hemostasis in the ulcer gastro-duodenal hemorrhage, using high-frequency biological welding electro-ligature
Objective. To improve the efficacy of endoscopic hemostasis for the ulcer gastro-duodenal hemorrhage, using high-frequency biological welding electro-ligature.
Materials and methods. In 2017-2020 yrs period the analysis of efficacy of endoscopic hemostasis was done in 160 patients, ageing 40-85 yrs old, for the ulcer gastro-duodenal hemorrhage. The patients were distributed into two groups: the main - 80 patients, in whom high-frequency biological welding electro-ligature was performed, and a control one - 80 patients, in whom monopolar thermal argon-plasm coagulation was conducted.
Results. In the main Group a primary hemostasis was achieved in 77 (96.3%) patients. Early recurrence of hemorrhage have occurred in 3 (3.8%) patients. In a control Group a primary hemostasis was achieved in 66 (82.5%) patients. Recurrence of the hemorrhage have occurred in 14 (17.5%) patients.
Conclusion. Endoscopic hemostasis for the ulcer gastro-duodenal hemorrhage, using high-frequency biological welding electro-ligature, is achieved due to the impedance action of modulated signal of a high-frequency current as well as the adaptive system of automatic guidance of the welding process and a contact between special endoscopic probe, owing a concave electrode, with bleeding vessel, leading to its complete obliteration. Application of welding electro-ligature for endoscopic hemostasis in the ulcer gastro-duodenal hemorrhage, using high-frequency biological welding electro-ligature, guarantees more secure residual hemostasis, than application of monopolar thermal argon-plasm coagulation, peculiarly in hemorrhage from vessels owing 2 - 4 mm diameter. As a result, the hemorrhage recurrence rate have had reduced down to 3.8% (in the control Group - 18.0%).
