A 73-year-old woman was admitted to the hospital because of dysphagia. Esophgoscopy showed type 3 tumor at the lower thoracic esophagus and esophagogastric junction. Endoscopic biopsy confirmed Siewert type II adenocarcinoma of esophagogastric junction. Abdominal and chest CT examination revealed no lymph node and distant metastases. Clinical stage was II (T3, N0, M0). The patient underwent a thoracosopic subtotal esophagectomy in the prone position, and a laparoscopy assisted reconstruction of gastric tube in the supine position. Pathological diagnosis was well differentiated adenocarcionma (pT3, pN0, sM0, ly3, v1, fStage II). Postoperative course was uneventful. We attempted thoracosopic esophagectomy in the prone position to treat Siewert type II adenocarcinoma of esophagogastric junction.
