Argon plasma coagulation (APC) is a new modality of electrosurgery to apply high frequency electric current into tissue to cause defined thermal and coagulating effects and may be beneficial for hemostasis of gastrointestinal bleeding. The aim of the present study was to assess prospectively the usefulness of endoscopic APC for peptic ulcer bleeding. Methods Patients with upper GI bleeding manifested by hematemesis or melena were included in this study. APC was carried out with the use of argon source APC 300 and high frequency generator ICC 200 (ERBE, Germany) when active bleeding from an ulcer or a visible vessel in an ulcer bed was found. Results A total of 23 patients with bleeding from peptic ulcer underwent APC. Arterial spurting was found in 5 patients, oozing in 10 and a visible vessel in 8. Initial hemostasis was achieved in 19 of 23 patients (83%). With respect to the type of bleeding, hemostasis success was 4/5 (80%) in patients with spurting, 8/10 (80%) with oozing, and 7/8 (88%) with a visible vessel. In the particular patients in whom endoscopic clipping failed to get hemostasis, hemostasis was achieved in 6/8 (75%). In terms of location, the rate of hemostasis by APC was 8/9 (89%) for lesions located in the body, 4/4 (100%) in the angle, 3/4 (75%) in the antrum, and 4/6 (67%) in the duodenum, with no significant difference. For the posterior lesions where frontal access was hard to obtain, APC resulted in a higher rate of hemostasis (86%). Rebleeding within 10 days was observed in 4/19 (21%) after initial hemostasis. No serious complication was encountered. Conclusions Endoscopic APC for bleeding peptic ulcerations resulted in a higher rate of initial hemostasis with a considerably lower rate of rebleeding. In patients with unsuccessful hemostasis by endoscopic clipping, a high rate of hemostasis was achieved by APC. Thus, APC may provide an effective and safe modality for treatment of bleeding ulcerations., 原著, Original},
