Infrapyloric artery(IPA) is of great importance for gastric cancer patients. In early gastric cancer patients, the pylorus-preserving gastrectomy requires the preserving of IPA. In advanced gastric cancer patients, the subgroup of No. 6 lymph node might be associated with IPA. In Japanese Gastric Cancer Association(JGCA) gastric cancer classification guidelines, the No. 6 lymph nodes is defined as lymph nodes along the first branch and proximal part of the right gastroepiploic artery(RGEA) down to the confluence of the right gastroepiploic vein and the anterior superior pancreatoduodenal vein. However,if IPA origins from the gastroduodenal artery(GDA) or anterior superior pancreatoduodenal artery(ASPDA), the lymph nodes along the IPA can not be grouped into the No. 6 lymph nodes. Thus, a new definition of No. 6 lymph nodes is needed on the basis of the origin of IPA.
Previous studies about IPA origin are few and the origin of IPA varies greatly among different studies.

Patients who would receive total gastrectomy or distal gastrectomy are enrolled in to the study and this group. An optional reconstruction of IPA by enhanced CT scan can be performed before surgery but not a definite require. During the operation, IPA origin location will be photo-taken or video-recorded before its transection.
Patients with gastric cancer that needs receiving total or distal gastrectomy. During the surgery, IPA needs to be exposed and transected.
Other Name: surgery
- Distribution of IPA origin [ Time Frame: Immediately after surgery ]The percentage of IPA origin from GDA, ASPDA and RGEA.
- Reconstruction rate of IPA by CT scan [ Time Frame: Immediately after the reconstruction of CT scan. ]The rate of identification of IPA origin by reconstruction of CT scan.
