4 - Greater curvature nodes
4 - Nodi curvaturae majori
Definition
The greater curvature lymph nodes ((Station number 4 in the gastric lymph node stations - Japanese Research Society for Gastric Cancer) are divided into two groups separated by the Von Ghoete point, where right and left gastroepiploic arteries meet each other at full channel: a left group (4s) and a right group (4d) Moreover, the left group is divided into a proximal part (4sa) and a distal part (4sb). lymph nodes of the proximal part of left group 4 (4sa) are located around the short gastric vessels while lymph nodes of the distal part (4sb) are located along the left gastroepiploic vessels. lymph nodes of the right part of group 4 are located along the right gastroepiploic vessels, distal to the first gastric branch (boundary with infrapyloric lymph nodes).
