Passaro's triangle

Passaro's triangle or Gastrinoma triangle is a presumptive region in the abdomen between three points:

  1. confluence of the cystic and common bile duct,
  2. junction of the second and third portion of duodenum, and
  3. junction of the neck and body of the pancreas.

The importance of the triangle is because it has been known as the source of originating most of the gastrinomas.[1][2]

The appellation is due to Edward Peter Passaro, an American surgeon, who explained it for the first time.[3]
