Question

Identify the triangle in the image below

• A. Koch’s triangle
• B. Gastrinoma triangle
• C. Hesselbach’s triangle
• D. Sherren’s triangle

Answer 1

The Correct Option is B

In the context of various anatomical triangles related to physiology, it is essential to accurately identify each based on their specific location and boundaries. In this case, the triangle described in the image is the Gastrinoma triangle.

The Gastrinoma triangle, also known as the “Passaro’s triangle,” is an anatomical area of clinical importance as it is often associated with gastrin-secreting tumors (gastrinomas), which are a cause of Zollinger-Ellison Syndrome. This triangle is formed by the following boundaries:

• Superiorly: The cystic duct
• Inferiorly: The second and third parts of the duodenum
• Medially: The neck of the pancreas

Understanding these landmarks helps in diagnosing and managing conditions related to excessive gastric acid secretion due to gastrinomas.
