Description

<jats:title>Abstract</jats:title><jats:p>In previous reports of laparoscopic pancreaticoduodenectomy, the <jats:styled-content style="fixed-case">K</jats:styled-content>ocher maneuver with a wide mobilization of the right colonic flexure is carried out in the early phase, and dissection of the superior mesenteric artery is performed in the last phase of resection. This report describes laparoscopic superior mesenteric artery first approach, in which the superior mesenteric artery is dissected in the early phase of resection. Through the ligament of <jats:styled-content style="fixed-case">T</jats:styled-content>reitz, the retroperitoneum is widely opened and the superior mesenteric artery is isolated just superior to the left renal vein. The periarterial connective tissue and nerve plexuses surrounding the superior mesenteric artery are dissected longitudinally to identify the inferior pancreaticoduodenal artery, which is then tied and divided. The superior mesenteric artery first approach and early ligation of the inferior pancreaticoduodenal artery is considered to be a feasible, safe, and effective method for performing pure laparoscopic pancreaticoduodenectomy.</jats:p>
