Popis: Abstract Background Endoscopic submucosal dissection (ESD) is gradually turning into the standard treatment for superficial esophageal squamous cell carcinoma (SESCC), however, the long-term outcomes have hardly ever been reported outside Japan. Method We consecutively recruited patients with SESCC who had received ESD treatment at E-Da Hospital. The demographics, pathological characteristics, and Lugol staining background pattern (type A or B: none or 10 small or multiform LVLs) were collected, and then correlated to outcomes and survival. Results Total of 229 lesions were enrolled and the mean lesion size was 3.28 ± 1.69 (range 1–10) cm. 72% of the lesions had a type C-D Lugol staining background pattern. After ESD, the en bloc and R0 resection rates were 93.9% and 83.5%, respectively. Forty-nine subjects developed complications, including six (2.6%) with major bleeding, two (0.9%) with perforation, and 41 (17.9%) with strictures. Pathological staging showed that 19 cases had deep submucosal cancer invasion and subsequently received adjuvant therapies. During a mean follow-up period of 52.6 (range 3–146) months, 41 patients developed metachronous recurrence. The patients with a type C-D Lugol staining background pattern were associated with a higher risk of recurrence than those with few LVLs (log-rank P = 0.019). The 10-year survival rate was more than 90%, and only eight patients died of ESCC. Conclusion ESD has excellent long-term outcomes but a high risk of metachronous recurrence. The Lugol staining pattern over the background mucosa could offer the risk stratification of metachronous recurrence.
