Our department consists of four divisions; Esophago-Gastric Surgery, Colorectal Surgery, Hepato-Biliary-Pancreatic Surgery and Vascular Surgery. Recently, endoscopic surgery has become a major operative procedure for gastroenterological surgery, and we are doing our best to further advance our surgical techniques and to extend operative indications of endoscopic surgery so that we provide our patients safe and fine minimally-invasive surgeries across the fields. In the field of vascular surgery, interventional radiology (IVR) plays a major role in recent years. We offer multiple treatment options combining surgery and IVR for patients with vascular diseases.
