采用kocher手法，分离十二指肠降部与下腔静脉之间间隙；分离胃结肠韧带，不保留大网膜，进入小网膜囊，小网膜囊后壁下面即为胰腺前缘；分离横结肠系膜前叶及胰腺背膜，于胰腺下缘找到肠系膜上静脉，分离钳顺着肠系膜上静脉在胰腺后侧打洞分离，直至门静脉；解剖肝十二指肠韧带，游离肝门三管；分别于胃大弯和胃小弯游离韧带，于固定处用直线切割闭合器切断胃；于预定切除处断胰；仔细分离钩突与SMV之间的小静脉、以及可能出现的胃结肠干、胃网膜右静脉等血管；施行胰肠吻合、胆肠吻合、胃肠吻合。

The kocher technique was used to separate the space between the descending part of duodenum and the inferior vena cava, to separate and resect the gastrocolonic ligament, then to enter the small reticular sac, and to separate the anterior lobe of the transverse mesocolon from the dorsal membrane of the pancreas under the posterior wall of the lesser omental sac. The superior mesenteric vein was found at the lower margin of the pancreas, and the separation forceps were perforated along the superior mesenteric vein to the posterior side of the pancreas until the portal vein; the hepatoduodenal ligament was dissected to free the porta hepatis; the free ligament was located in the greater curvature of the stomach and the lesser curvature of the stomach, respectively. The stomach was cut off by using a straight line stapler, the pancreas was cut off at the predetermined resection site, the venules between the uncinate process and SMV, and the possible blood vessels such as gastrocolic trunk and right gastroepiploic vein were carefully separated. Therefore pancreaticojejunostomy, choledochojejunostomy and gastrointestinal anastomosis were performed respectively.
