From Wikipedia, the free encyclopedia

Passaro's triangle or gastrinoma triangle is a presumptive region in the abdomen between three points:
- Superior—porta hepatis[1] (earlier—confluence of the cystic and common bile duct),[2]
- Inferior—junction of the second and third portion of duodenum,[2] and
- Medial—junction of the neck and body of the pancreas[2]
The importance of the triangle is because it is known as the source of origin of most gastrinomas.[3][4] However, primary gastrinomas can also occur in the liver or extrahepatic bile ducts, commonly with metastasis to the local lymph nodes.[5]
The appellation is due to Edward Peter Passaro, an American surgeon, who explained it for the first time in the year 1984.[3] [6]
