What condition can cause obstructive jaundice secondary to biliary tract obstruction?

Obstructive jaundice occurs when there is a blockage in the biliary tract that prevents bile from flowing into the intestines, leading to the accumulation of bilirubin in the bloodstream. One of the key conditions that can cause this type of jaundice is acute cholangitis, which refers to an infection of the bile duct usually caused by a blockage (for example, from gallstones or tumors). The obstruction not only prevents bile from draining but can also lead to infection and inflammation in the biliary tree, causing a rapid increase in bilirubin levels and presenting as jaundice.

In the context of acute cholangitis, the classic triad of symptoms includes jaundice, fever, and abdominal pain, which can help differentiate it from other conditions. Early recognition and treatment are crucial as it can lead to serious complications if untreated.

Other conditions listed may cause their own complications related to the biliary system, but they do not typically lead to obstructive jaundice in the same way that acute cholangitis does. For instance, acute cholecystitis primarily involves inflammation of the gallbladder and may lead to complications, but it does not directly obstruct the common bile duct. Acute pancreatitis can lead to complications such as pseudocysts
