[Value of identification of renal pedicles in the echotomographic study of the normal and pathological pancreas].

The renal pedicles were identified in 83.5% of pancreases during echotomography. The horizontal relations together with the vertical relations represented by the abdominal aorta and inferior vena cava permit one to localise with precision the cephalic and corporeal parts of the pancreas for they are situated just in front. Analysis of the echostructure of the pancreas thus localised is greatly facilitated.
