Abstract

Objectives: To assess the efficacy of endoscopic submucosal dissection for the treatment of early esophageal cancer at the Gastroenterology and Hepatobiliary Center, Bach Mai Hospital. Subjects and methods: A retrospective study of 36 patients with early esophageal cancer treated with endoscopic submucosal dissection at the Gastroenterology and Hepatobiliary Center, Bach Mai Hospital from January 2020 to January 2025. Results: Bleeding during ESD 5.6%. Esophageal stricture after ESD 8.3%. No air leakage, infection, perforation during and after ESD. No recurrence, distant metastasis in in patients re-examined during 5 years of follow - up; The en-bloc resection rate was 100%; Complete resection rate was 91.7%; Early esophageal cancer invades the epithelium (M1), Lamina propria mucosa (M2) was 77.8%; Muscularis mucosae (M3), Submucosa (SM1 <200 µm) was 19.4%; SM2, SM3 (>200 µm) was 2.8%. No lymph node invasion, no distant metastasis. Conclusion: Endoscopic submucosal dissection is an effective and safe technique in the treatment of early esophageal cancer.
