Overview

An upper transverse line, the transpyloric is located halfway between the jugular notch and the upper border of the symphysis pubis; this indicates the margin of the transpyloric plane, which in most cases cuts through the pylorus, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebra.

Structures crossed

The transpyloric plane is clinically notable because it passes through several important abdominal structures. These include:

• the fundus of the gallbladder
• the neck of the pancreas
• the origins of the superior mesenteric artery and portal vein
• the hila of the kidneys
• the root of the transverse mesocolon
• the duodenojejunal junction
• the 2nd part of the duodenum
• the termination of the spinal cord
• the spleen
