In this study, we performed laparoscopy-assisted distal gastrectomy (LADG) and lymph node dissection with an incision of 3 cm aiming at radical cure and low invasiveness. We introduce and discuss this technique of minilaparotomy and recommend a device for anastomosis. In LADG, a skin incision of 5cm or greater is made in order to pull out the stomach in other institutes. Whether function is distinctly better after laparoscopy-assisted surgery than after abdominal section has not been elucidated so far, so we should seek an aesthetic advantage. We have used a 3-cm abdominal wound to date. If the wound is smaller than this, the body of the SDH25 cannot be inserted, and currently a wound less than 3cm may thus not be possible. The shaft of the SDH is straight, making it easy to confirm the direction even through a laparoscope. The shaft of the anvil head of the PPCEEA is too long, so that when it is connected with the body through the 3-cm incision, it is necessary to draw it through the remnant stomach to a great extent.
