Background: Walled-off necrosis is a common complication of severe pancreatitis. Guidelines recommend endoscopic transgastric necrosectomy as therapy of choice. Different endoscopic approaches are possible. Methods: We retrospectively analyzed our series of 9 patients where necrosectomy was performed after application of a lumen-apposing metal stent (LAMS) delivered using a Hot AxiosTM Stent device. Results: In all 9 cases, the walled-off necrosis resolved completely. Necrosectomy was performed through the LAMS (mean: 5.7 times). Endoscopic necrosectomy was repeated every 3rd–7th day using 10- or 15-mm snares. There were no major complications. Especially, no early or delayed bleeding was seen. Conclusion: The Hot AxiosTM Stent device is a safe method for necrosectomy of walled-off necrosis. It enables puncture, drainage, and LAMS insertion in a single delivery, followed by several courses of necrosectomy if needed without stent exchange.
