Abstract: A technique, by which the root of the right gastric artery can be clearly exposed and the area of the right gastric artery can thus be completely dissected, is presented herein. In conventional procedures, the approach to the right gastric artery is performed from the lessor omentum, and a lymphadenectomy along the common hepatic artery is carried out after the division of the right gastric artery. Using the present technique, the common hepatic artery is exposed before the exposure of the right gastric artery and lymph node dissection is thus continued peripherally to the proper hepatic artery. During these procedures, the root of the right gastric artery arising from the hepatic artery can be easily identified. The lymphatic flow from the area of the right gastric artery to that of the common hepatic artery is transected using the conventional procedure, but not with the present technique. In addition, an en bloc dissection of the regional lymph nodes is also possible when using this procedure.
