Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for hypopharyngeal hemangioma.Methods:A retrospective analysis was performed on data of patients with hypopharyngeal hemangioma who were treated with ESD at the endoscopy center of Zhongshan Hospital, Fudan University from October 2023 to February 2024. The en bloc resection rate, complete resection rate, procedure time, length of hospital stay, and incidence of adverse events were recorded.Results:A total of five patients were included, aged 28-78, four females and one male, with a median tumor long diameter of 1.5 cm (1.0-4.0 cm). All ESD procedures were successfully performed for hypopharyngeal hemangioma, and the rate of en bloc resection was 80.0% (4/5). Complete resection rate was 100.0% (5/5). The median procedure time was 35 minutes (18-60 minutes). None of them underwent prophylactic tracheotomy, and all of them were confirmed as hemangiomas by postoperative pathology. Open diet 1 day postoperatively, and the median length of hospital stay was 6 days (3-8 days). There were no serious adverse events related to ESD during or after the procedure.Conclusion:ESD can be a potential new method for the treatment of hypopharyngeal hemangioma, demonstrating satisfactory effectiveness and safety.
