Laparoscopy‐assisted Pylorus‐preserving Gastrectomy: Preservation of Vagus Nerve and Infrapyloric Blood Flow Induces Less Stasis

Abstract
Pylorus-preserving gastrectomy (PPG) prevents postprandial symptoms; however, delayed gastric retention due to aberrant pylorus function can occur during the early postoperative period. This study aimed to establish a stasis-less PPG procedure with preservation of the vagal nerve and blood flow to the pyloric cuff, and to apply the technique for laparoscopy-assisted PPG.
