Total gastrectomy or proximal gastrectomy is usually performed either as an open procedure or laparoscopically for the treatment of early gastric cancer (EGC) in the upper stomach. However, quality of life after either total or proximal gastrectomy is not so satisfactory. The authors report a novel surgical procedure, laparoscopy-assisted subtotal gastrectomy (LAsTG), by which a very small remnant stomach is preserved, for the surgery of selected EGCs in the upper stomach. Twenty-three patients with EGC in the upper stomach underwent LAsTG. After lymph node dissection and mobilization of the stomach, the stomach was transected about 2 cm proximal to the tumor and a very small remnant stomach was preserved. An anvil was inserted transorally into the remnant stomach by using the OrVil system. The reconstruction method was Roux-en-Y, and hemidouble-stapling gastrojejunostomy with a circular stapler was performed intracorporeally. There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 266.7 min and 54.6 ml, respectively. The overall incidence of early postoperative complications was 17.4%, and two patients underwent reoperation because of duodenal stump leakage and stenosis of the Y-anastomosis, respectively. During the follow-up period, two patients experienced gastrojejunostomy stenosis and both were treated successfully by endoscopic balloon dilation. LAsTG may be performed in selected patients with EGC in the upper stomach. With the described method, a very small remnant stomach can be preserved.
