Summary
Brief summary (as posted)
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.

Arms (1)
- label
- Observational group
- description
- 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.
- interventionNames
- Procedure: Gastrectomy
Primary outcomes (1)
- measure
- Distribution of IPA origin
- timeFrame
- Immediately after surgery
- description
- The percentage of IPA origin from GDA, ASPDA and RGEA.
Secondary outcomes (1)
- measure
- Reconstruction rate of IPA by CT scan
- timeFrame
- Immediately after the reconstruction of CT scan.
