What is a triangle in stomach?

Passaro’s triangle or Gastrinoma triangle is a presumptive region in the abdomen between three points: of Gallbladder (Earlier-confluence of the cystic and common bile duct), Inferior-junction of the second and third portion of duodenum, and. Medial- junction of the neck and body of the pancreas.

Where is the Gastrinoma triangle?

The gastrinoma triangle is defined as the confluence of the cystic and common bile duct superiorly, the second and third portions of the duodenum inferiorly, and the neck and body of the pancreas medially, both dorsally and ventrally (Figure 1).

Is gastrinoma a cancer?

All gastrinomas are cancers. Some gastrinomas grow slowly and don’t spread to other parts of the body. Others can spread to other parts of the body (metastases).

What are the different parts of the pancreas?

The pancreas has three main sections:

  • Head: area of pancreas to right of left border of superior mesenteric vein.
  • Body: area of pancreas between left border of superior mesenteric vein and left border of aorta.
  • Tail: area of pancreas between left border of aorta and hilum of spleen.

What does Gastrinoma mean?

Listen to pronunciation. (gas-trih-NOH-muh) A tumor that causes overproduction of gastric acid. It usually begins in the duodenum (first part of the small intestine that connects to the stomach) or the islet cells of the pancreas.

What is a Vipoma?

VIPomas are rare functioning neuroendocrine tumors that secrete vasoactive intestinal polypeptide (VIP) [1,2]. This topic will review the clinical manifestations, diagnosis, and management of VIPomas.

What is Verner Morrison syndrome?

The Verner-Morrison syndrome is characterised by a profuse, watery diarrhoea that results in massive intestinal loss of water, potassium, sodium and bicarbonate, leading to hypovolaemia, hypokalaemia and reduced total body potassium, and achlorhydria (metabolic acidosis).

What is Zollinger?

Zollinger-Ellison syndrome is a rare digestive disorder that results in too much gastric acid. This excess gastric acid can cause peptic ulcers in your stomach and intestine. Symptoms include abdominal pain, nausea, vomiting, weight loss, and diarrhea.

In which organ is Gastrinoma usually found?

Gastrinomas are neuroendocrine tumours that are usually found in the first part of the small intestine or in the pancreas, which produce excess amounts of the hormone called gastrin.

Who is the inventor of the gastrinoma triangle?

Edward Peter Passaro (1930-2017) was an American GI surgeon, who described his eponymous triangle in 1984 2. 1. Horton KM, Hruban RH, Yeo C et-al. Multi-detector row CT of pancreatic islet cell tumors.

What kind of tumor is a gastrinoma?

Gastrinomas are rare, usually small tumors that can originate from G cells in the pancreas, stomach or small intestine. Most gastrinomas are malignant. Gastrinomas can be solitary or develop in clusters, and can occur sporadically or be associated with multiple endocrine neoplasia type 1 (MEN-1).

Which is more common gastrinoma or pancreas metastasis?

Tumor localization: 60-90% gastrinomas arise within the Gastrinoma triangle. Gastrinoma is more common in duodenum than in pancreas. 2. Hepatic metastases: Gastrinomas that arise from the tail of pancreas have higher rate of hepatic metastases compared to that which arises in gastrinoma triangle.
