探查胃窦肿物，见浆膜层受累，第6组淋巴结转移可能性大，建议进行14v组淋巴结清扫。过程包括打开胃结肠韧带，解剖胃结肠静脉干、肝十二指肠韧带、小网膜、胃胰皱襞，分别于根部离断胃网膜左血管、胃网膜右血管、胃右血管、胃左血管，清扫第1、3、4、5、6、7、8、9、11p、12a、12p、14v组淋巴洁，完成D2腹腔淋巴结清扫。腔镜下离断十二指肠及部分远端胃，标本取出后行胃十二指肠毕I式吻合(四角吻合)。

Exploring the gastric antrum tumor, the serosal layer was found to be involved. No.6 lymph node (LN) has a high rate of metastasis, and is need to perform the No.14v LN dissection. The operation procedure include transection of gastrocolic ligament, dissection of gastrocolic trunk, hepatoduodenal ligament, lesser omentum and pancreatic stomach plica. Left gastric omentum vessels, right gastric omentum vessels, right gastric vessel and left gastric vessel were transected at the root. No.1、3、4、5、6、7、8、9、11p、12a、12p、14v lymph nodes were dissected, and D2 abdominal javascript: ; lymphadenectomy was completed. After laparoscopic transection of the distal stomach and duodenum, we removed the en-block specimen, then augmented rectangle anastomosis (ART) was performed.
