Is common bile duct dilatation associated with normal liver function tests?
Background: There is scant literature about common bile duct (CBD) dilatation with normal liver function tests (LFTs).
What causes focal dilatation of the bile duct?
Focal dilatation may be a result of downstream stricture, or damage to the elasticity of that segment of the bile duct, possibly from prior stone passage. Color Doppler can be useful to ensure that dilated structures in the liver are actually bile ducts and not an intrahepatic vascular malformation.
What is the common hepatic duct (CD)?
usually measured in the proximal duct, near the proper hepatic artery it is common practice to refer to the common hepatic/bile duct as the common duct ( CD) when reporting ultrasound, as the confluence of the cystic duct with the common hepatic duct (CHD) to form the common bile duct (CHD) is often not clearly defined.
What does a dilated common duct mean?
The common duct is the tubular structure that delivers the bile from the liver-gallbladder to the small bowel. When the gallbladder is removed, the common bile duct dilates. If a patient has a dilated common duct and still has their gallbladder then this is much more source for concern.

Are dilating bile ducts a cause for concern? | Gut
See article on page 741 Whether the bile duct dilates after cholecystectomy is a hoary old chestnut dating back to Oddi and hotly debated in the era of intravenous cholangiography but is still of practical importance now. In this issue Majeed et al (see page 741) report a careful, but uncontrolled study from Sheffield examining this question. Fifty nine patients undergoing cholecystectomy had ...

Background and study aims: Although abdominal ultrasonography (US) is a good initial screening method for detection of biliary tract disease, we sometimes encounter patients who only have findings of dilatation of the common bile duct (CBD) on US, without specific biliary symptoms or jaundice. This study aimed to evaluate the causes and clinical significance of dilatation of the CBD in ...
What causes bile duct dilation?
Choledocholithiasis. Choledocholithiasis is the most common cause of bile duct dilatation in patients with gallstones. Approximately 85% of obstructing bile duct stones are found in the distal duct near the head of the pancreas. This region of the duct is often difficult to visualize with ultrasound.
What is the cause of stagnation in the bile flow?
Interference to bile flow caused by adult flukes or eggs causes stagnation, which leads to secondary bacterial infection, pigment stone formation, and pyogenic cholangitis. 128 Demonstration of ova, or fragments of parasites, within stones provides support to this theory.
Can bile duct fibrosis cause bile duct dilation?
Disorders such as sclerosing cholangitis, acquired immunodeficiency syndrome, and chemotherapy-induced biliary sclerosis can present with bile duct fibrosis, impeding the ability of the bile ducts to become dilated. Conversely, bile duct dilatation does not always imply the presence of an obstructed biliary system.
Does bile duct dilation always imply obstruction?
Conversely, bile duct dilatation does not always imply the presence of an obstructed biliary system. For example, dilatation that may be seen in patients with Caroli disease, or choledochal cysts, can have the radiographic appearance of bile duct dilation without the presence of obstruction.

What causes enlarged bile ducts?
Gallstones are one cause of bile duct enlargement. In fact, gallstones are a build-up of bile, which forms small stone-like clumps that can lead to blockages if they get large. This is one of the most common causes of bile enlargement. However, there are other reasons for a person to have the problem.
Why is my bile duct enlarged?
Here’s a look at some of the other causes of enlarged bile ducts: Inflammation. Inflammation of the bile duct can occur due to infection , which then leads to enlargement. Porta hepatis.
What is the yellowish brownish substance that the bile duct normally carries from the liver and gallbla?
It is a yellowish-brownish or dark-green substance that the bile duct normally carries from the liver and gallbladder through the pancreas to the duodenum, which is part of the small intestine. Bile essentially helps digest fats from the food we eat. If a blockage or obstruction occurs in the bile duct, it enlarges.
What is the function of bile ducts?
Bile ducts have a major function when it comes to our well-being. Having an enlarged bile duct can lead to uncomfortable pain as well as a host of other symptoms. Bile is a liquid produced by our liver. It is a yellowish-brownish or dark-green substance that the bile duct normally carries from the liver and gallbladder through the pancreas to ...
What is the name of the surgeon who removes the liver and bile ducts?
There are doctors who specialize in treating the liver and bile ducts as well. They are called hepatobiliary surgeons. Let’s take a look at all the options for cancer: Surgical removal of the bile duct—The surgeon removes the entire organ. The operation could also include removal of lymph nodes to check for cancer.
What is the treatment for bile duct cancer?
Chemotherapy —This is the use of drugs to destroy cancer cells. Chemo is meant to stop cancer cells’ ability to grow and divide. Sadly, bile duct cancers are resistant to many types of chemotherapy , so clinical trials are the best way to try this type of treatment.
Can a tumor in the pancreas cause bile ducts to enlarge?
It eventually spreads throughout the liver. A tumor at the head of the pancreas can also lead to enlargement of the bile duct. When doctors take a close look at what causes enlarged bile ducts, they often discover that diet plays a big role. For example, gallstones are commonly linked to a high cholesterol diet.

What happens to the bile duct after cholecystectomy?
When a patient has their gallbladder removed, the common bile duct dilates over some time. Dilated common bile after a cholecystectomy is of no significance by itself and should only be considered important if there are other findings, such as pancreatitis or elevated liver function tests.
What is the common bile duct?
Common Bile duct is part of the “plumbing” that drains the secretion of the liver (bile) into small bowel (duodenum). The size of the common bile duct, if dilated, may suggest a blockage downstream. This is a specific finding that is looked for when a patient gets an ultrasound for a suspected liver or Gallbladder disease.

I am not sure gallbladder dilates common duct. Gallbladder removal over time will result in dilation of the common duct.
What causes intrahepatic duct dilation?
Similar to extrahepatic duct dilatation, a mechanical biliary obstruction is the most common cause of intrahep-atic bile duct dilatation. Intrahepatic biliary dilatation in mechanical obstruction is generally tubular and lacks focal stricture formation. Caroli disease, recurrent pyogenic cholangitis, polycystic liver disease, primary sclerosing cholangitis, choledochal cyst, and peribiliary cysts should be included in the differential diagnosis of cystic intrahepatic biliary dilatation. Caroli disease is suggested by focal or diffuse biliary dilatation that is cystic or fusiform in character (Fig. 3) [10, 11]. When diffuse involvement is present, the bile ducts converge
Is sclerosing cholangitis a duct dilation?
Although intrahepatic bile duct dilatation is a feature of primary sclerosing cholangitis, the duct dilatation is typically fusiform and isolated. The degree and extent of duct dilatation in primary sclerosing cholangitis is not as severe as that in obstructive biliary dilatation, Caroli disease, or recurrent pyogenic cholangitis because fibrosis, stricture formation, and secondary cirrhosisare the major features of primary sclerosing cholangitis.
