Endoscopic submucosal dissection (ESD) is a technique that allows en bloc resection of early lesions of the digestive tract. It has curative potential in selected patients and potential benefits over esophagectomy for the treatment of esophageal cancer (EC). Aim: To report the results of ESD for EC in a high-volume center in Chile. Materials and Method: Retrospective descriptive study of patients who underwent ESD for EC at our center. Results: A total of 10 patients were treated with ESD for EC between 2010 and 2020. Eighty percent were male patients, the average age was 72 years (63-84). En bloc resection was achieved in all cases and there were no complications or mortality. All of the dissections were classified as R0 and 90% met curative standards. The mean follow-up was 38 months (3.5-123). Overall survival was 90%. Cancer-specific survival was 100% and recurrence-free survival was 100%. Discus-sion: The rate of morbidity and mortality of esophagectomy is high. ESD would be a safer technique, which allows R0 resections and eventually curation in selected patients with EC limited to the mucosa or submucosa. Conclusion: This is the first report of ESD for the treatment of EC in our country, it shows excellent oncologic results and safety of the procedure, comparable to those reported in the larger series published to date.
