A 64-year-old man presented with dysphagia. Esophagogastroduodenoscopy revealed a submucosal tumor of 52mm in size at the lower thoracic esophagus. Biopsy yielded a pathological diagnosis of c-kit-positive esophageal gastrointestinal stromal tumor(GIST). We started neoadjuvant therapy with imatinib to avoid excessive surgical invasion. After 6 months of treatment, CT revealed a reduction in tumor size to 27 mm. We performed laparoscopic lower esophagectomy, proximal gastrectomy, double-tract reconstruction, and complete tumor resection. Neoadjuvant imatinib therapy was effective for the esophageal GIST.
