INTRODUCTION The hemi-double stapling method (HDS) is typically used for extracorporeal Billroth-I anastomosis. We used HDS for reduced-port surgery. Laparoscopic HDS is used for intracorporeal Billroth-I anastomosis after laparoscopic distal gastrectomy. We performed reduced-port laparoscopic distal gastrectomy for gastric cancer. METHODS Reduced-port(More)
