The Origin of Infrapyloric Artery

Infrapyloric artery(IPA) is of great importance for gastric cancer patients. According to previous study, the origin of IPA varies greatly among different studies. This trial aims to tell the distribution of IPA origin in Chinese patients.

About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients with gastric cancer who needs to receive total or distal gastrectomy.
  • Signed informed consent

Exclusion criteria

  • IPA not dissected, photo-taken or video-recorded.

Treatment and study plan

gastrectomy

Procedure

Patients with gastric cancer that needs receiving total or distal gastrectomy. During the surgery, IPA needs to be exposed and transected.

Other names: surgery
