A 65-year-old male was referred to our hospital for the treatment of early gastric cancer. The patient was treated with endoscopic submucosal dissection (ESD). As a result of ESD, the depth of invasion was SM1250 μ, and we performed laparoscopic distal gastrectomy. Computed tomography showed a type VI vascular anomaly in Adachi’s classification. Preoperative vascular construction allowed us to perform the operation without intraoperative complications. To safely perform this operation, preoperative CT angiography is very important.
