LID - 10.1007/s10620-024-08389-7 [doi] AB - AIM: Endoscopic necrosectomy has become the first-line treatment option for infectious necrotizing pancreatitis (INP), especially walled-off necrosis. However, the problems, including operation-related adverse events (AEs) and the need for multiple endoscopic procedures, have not been effectively addressed. We sought to evaluate the clinical safety and efficacy of anhydrous ethanol-assisted endoscopic ultrasound (EUS)-guided transluminal necrosectomy in INP. METHODS: A single-center observational cohort study of INP patients was conducted in a tertiary endoscopic center. Anhydrous ethanol-assisted EUS-guided transluminal necrosectomy (modified group) and conventional endoscopic necrosectomy (conventional group) were retrospectively compared in INP patients. The technical and clinical success rates, operation time, perioperative AEs, postoperative hospital stay, and recurrent INP rates were analyzed, respectively. RESULTS: A total of 55 patients were enrolled. No statistically significant differences were observed between the two groups regarding baseline characteristics. Compared to patients in the conventional group, patients in the modified group demonstrated significantly reduced times of endoscopic transluminal necrosectomies (1.96 +/- 0.89 vs. 2.73 +/- 0.98; P = 0.004) and comparable perioperative AEs (P = 0.35). Meanwhile, no statistically significant differences were observed in the technical and clinical success rates (P = 0.92), operation time (P = 0.59), postoperative hospital stay (P = 0.36), and recurrent INP rates (P = 1.00) between the two groups. CONCLUSION: Anhydrous ethanol-assisted EUS-guided transluminal necrosectomy seemed safe and effective in treating INP. Compared with conventional endoscopic transluminal necrosectomy, its advantage was mainly in reducing the number of endoscopic necrosectomies without increasing perioperative AEs. CI - (c) 2024.
