The nPTD classification. The ‘n’ zone is newly created as the region with a diameter of about 5 cm set on the watershed between the left and right gastroepiploic arteries on the greater curvature. The boundary between the P and T zones is changed to the line that links the watershed point between the left and right gastroepiploic arteries to the upper one-third point of the lesser curvature. Furthermore, the P zone is divided into two; the lesser curvature side (PL) and the greater curvature side (PG). The D zone is left unchanged. The lymphatic compartments are also displayed. This figure was newly created by the first author
