ABSTRACT
@#Objective To analyze the clinical characteristics of patients treated with esophagectomy following endoscopic submucosal dissection (ESD) for early stage esophageal cancer or precancerosis and the reasons for esophagectomy. Methods We retrospectively analyzed the clinical data of 57 patients who were treated with esophagectomy following ESD in West China Hospital and Shanxian Hygeia Hospital from January 2012 through October 2016. There were 42 males and 15 females at age of 65.4 (52–77) years. There were 15 patients of upper thoracic lesions, the middle thoracic lesions in 34 patients, and the lower thoracic lesions in 8 patients. Results The reasons for esophagectomy included 3 patients with residual tumor, 8 patients with local recurrence, 37 patients with esophageal stricture, and 9 patients with dysphagia, although the diameter was larger than 1.0 cm. The pathology after esophagectomy revealed that tumor was found in 16 patients, including 3 patients with residual tumor and 8 with recurrent tumor confirmed before esophagectomy, and 5 patients with new-found recurrent tumor. Conclusion In the treatment of early stage esophageal cancer or precancerosis, the major reasons for esophagectomy following ESD include esophageal stricture, abnormal esophageal dynamics, local residual or recurrence.
