When the intrahepatic bile duct wall has protrusions, it is clearly seen as central dots or a linear streak. [10] Caroli disease is commonly diagnosed after this “central dot sign” is detected on a CT scan or ultrasound. [10] However, cholangiography is the best, and final, approach to show the enlarged bile ducts as a result of Caroli disease.
Secondary extra-hepatic disorders involve organs excluding the liver. When a tumour develops at the pancreas head or bile duct, the common bile duct is compressed, opposing bile flow, eventually leading to hyperbilirubinemia. [4] Gallbladder carcinoma displays enlarged liver with Courvoisier's sign, a mass in the liver's right-upper quadrant. [27]
The bile duct [1] [4] (formerly known as the common bile duct [4]) is a part of the biliary tract. [4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the hepatopancreatic ampulla. It possesses its sphincter to enable the regulation of bile flow.
The function of the common bile duct is to allow bile to travel from the gallbladder to the small intestine, mixing with pancreatic digestive enzymes along the way. [4] One possible complication of choledocholithiasis is an infection of the bile ducts between the liver and the gallstone lodged in the common bile duct.

Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1] In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater , which drains via the major duodenal papilla to the second part of duodenum. [ 2 ]
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Without appropriate treatment, recurrent episodes of cholecystitis are common. [1] Complications of acute cholecystitis include gallstone pancreatitis, common bile duct stones, or inflammation of the common bile duct. [1] [8] More than 90% of the time acute cholecystitis is caused from blockage of the cystic duct by a gallstone. [1]
