What is Hepatocystic triangle?

Hepatocystic triangle (blue): Upper boundary of hepatocystic triangle is the inferior border of liver. Lateral, the cystic duct and the neck of the gallbladder. Medial, the common hepatic duct. Triangle of Calot (yellow): Upper boundary is the cystic artery. Lateral the cystic duct.

What are the contents of Calot’s triangle?

Calot’s triangle In its present interpretation the upper border is formed by the inferior surface of the liver with the other two boundaries being the cystic duct and the bile duct [Figure 5]. Its contents usually include the RHA, the cystic artery, the cystic lymph node (of Lund), connective tissue, and lymphatics.

What is the node of Calot?

The cystic lymph node of Lund (also known as the Calot or Mascagni node) is the sentinel node for the gallbladder, and one of the structures in Calot triangle. It lies in close proximity to the cystic artery and is one of the structures removed during cholecystectomy.

What structure runs through the Hepatocystic triangle to create the double inlet?

Hepatocystic triangle This triangle contains the cystic artery, a variable portion of right hepatic artery, the cystic lymph node, lymphatics, and a variable amount of fibro-fatty connective tissue[21].

What is frozen Calots triangle?

Calot described this triangle in 1891 formed by the cystic duct, hepatic duct, and the cystic artery. In reality, it is a space bounded by the cystic duct, hepatic duct, and the inferior surface of the liver. It contains the RHA, cystic artery, Lunds lymph node, connective tissue, and lymphatics.

What is inflammation of the bile duct?

Cholangitis is an inflammation of the bile duct system. The bile duct system carries bile from your liver and gallbladder into the first part of your small intestine (the duodenum). In most cases cholangitis is caused by a bacterial infection, and often happens suddenly.

Can Mirizzi syndrome be cured?

Surgery remains the preferred approach for the treatment of Mirizzi Syndrome. Laparoscopic cholecystectomy (LC), which has been used since 1987, was first reported to successfully treat Type 1 Mirizzi Syndrome by Paul et al.

How do you treat an inflamed bile duct?

Treatment includes antibiotics, supportive care and drainage of the bile ducts — surgically, endoscopically or percutaneously through the liver. Stones in the bile duct (choledocholithiasis) — a gallstone may form in the bile duct, causing an obstruction in the duct.

Is an enlarged bile duct serious?

A bile duct obstruction, also known as biliary obstruction, is when one of the ducts that carry bile from the liver to the intestine via the gallbladder becomes blocked. If left untreated, this blockage can lead to serious complications, including severe infection.

What is the Mirizzi syndrome?

Mirizzi syndrome is defined as common hepatic duct obstruction caused by extrinsic compression from an impacted stone in the cystic duct or infundibulum of the gallbladder [1-3]. Patients with Mirizzi syndrome can present with jaundice, fever, and right upper quadrant pain.

What is the significance of the triangle of Calot?

Clinical significance. Calot’s triangle, containing the cystic artery, may also contain an accessory right hepatic artery or anomalous sectoral bile ducts. As a result dissection in the triangle of Calot is ill-advised until the lateral-most structures have been cleared and identification of the cystic duct is definitive.

Is the cystic artery in the Calot triangle?

The Calot triangle, which contains the cystic artery, may also contain an accessory right hepatic artery or abnormal sectoral bile ducts. As a result, the dissection in Calot’s triangle is misguided until more lateral structures have been removed and the identification of the cystic duct is definitive.

Where is the Calot triangle in the liver?

Conclusion: The Calot’s triangle is an anatomical space in the right sub hepatic area and it is bounded medially by the common hepatic duct, laterally by the cystic duct and superiorly by the inferior border of the liver.

Is the stomach part of the Calot triangle?

The stomach was removed taking care not to damage the coeliac trunk. The inferior border of the liver was cut to expose the Calot’s triangle region for the ease of dissection and visualization. The common bile duct, its right, and left divisions and the cystic duct were dissected meticulously.
