Background/Purpose: Endoscopic submucosal dissection (ESD) is an advanced endoscopic procedure to resect early gastrointestinal neoplasm. It is technically more difficult and risky when used to treat early esophageal tumors. We report our experiences related to performing ESD for early esophageal neoplasia. The efficacy, complications, and outcome were also analyzed. Methods: From December 2007 to April 2010, 22 patients with documented early esophageal neoplasm underwent ESD. All patients completed a meticulous endoscopic examination using conventional endoscopy followed by narrow-band imaging. Lugol's staining was performed to identify the margin of the suspicious lesion. Insulation-tipped diathermic knife 2 was used for ESD. Results: A total of 26 neoplastic lesions (including 13 tumors with high-grade dysplasia, 12 tumors with squamous cell carcinoma, and one tumor with adenocarcinoma) in 22 patients were enrolled. All patients were men. The mean age was 47.6 ± 8.6 years (range, 30-68 years). The mean size of tumors was 33.7 ± 21.7 mm (range, 8-80 mm). ESD was performed for 24 lesions in 20 patients. The mean size of resected specimens was 43.1 ± 19.2 mm (range, 15-90 mm). The mean operation time was 92.7 ± 69. minutes (range, 30-310 minutes). There were three ESD-related complications, including one with delayed bleeding, one with subcutaneous emphysema, and one with perforation. Two patients received additional operations after ESD due to deep submucosal invasion by cancer. Three lesions in two patients (12.5%) developed post-ESD esophageal stricture that needed repeated endoscopic bougination. There was no procedure-related mortality. No local recurrence was found during the follow-up period. Conclusion: ESD is a promising local curative treatment option for early esophageal neoplasia in Taiwan. However, this procedure may result in complications that are worth noting, especially post-ESD esophageal stricture. Education regarding this procedure and more hands-on training will facilitate endoscopists to improve the outcomes of patients undergoing this procedure. © 2012, Elsevier Taiwan LLC & Formosan Medical Association.
