What condition is referred to when a stone is impacted in Hartmann's pouch, causing compression of the CBD?

The condition referred to when a stone is impacted in Hartmann's pouch, causing compression of the common bile duct (CBD), is Mirizzi's syndrome.

Mirizzi's syndrome occurs when a gallstone gets lodged in the cystic duct or the neck of the gallbladder, which leads to inflammation and potential compression of the adjacent CBD. This compression can cause obstructive jaundice due to the bile duct being compressed by the stone, resulting in a buildup of bile. The clinical presentation often includes symptoms of cholestasis such as jaundice, abdominal pain, and sometimes fever if there is associated cholecystitis.

It is important to differentiate this condition from others. Biliary atresia refers to a congenital condition of the bile ducts in infants, which does not involve stones. Chronic cholecystitis is a long-term inflammation of the gallbladder typically due to repeated episodes of irritation by gallstones, but it does not specifically relate to the compression of the CBD by an impacted stone in Hartmann’s pouch. Pneumobilia is the presence of air within the biliary tree, which is an entirely different phenomenon and generally indicates an abnormal communication between the biliary system and the gastrointestinal tract, often due to infection or
