The left and right hepatic ducts exit the liver and join to form the common hepatic duct in an area called the hilum. Lower down, the gallbladder (a small organ that stores bile) is joined to the common hepatic duct by a small duct called the cystic duct. This combined duct is called the common bile duct.
What does the hepatic duct do in the digestive system?
The common bile duct is a small, tube-like structure formed where the common hepatic duct and the cystic duct join. Its physiological role is to carry bile from the gallbladder and empty it into the upper part of the small intestine (the duodenum). The common bile duct is part of the biliary system.
Where does the common hepatic duct drain?
The bile flows through a series of small tubes (ducts) that drain into one large duct called the common bile duct, which then empties into the duodenum, the first part of the small bowel after the stomach. Bile is also stored in the gallbladder.
What is hepatic duct and cystic duct?
The right and left hepatic ducts exit the liver and then join together to form the common hepatic duct. The common hepatic duct and the cystic duct join to form the common bile duct. The cystic duct connects the gallbladder (a small organ that stores bile) to the common bile duct.
What does hepatic duct mean?
Hepatic duct: A duct that carries bile from the liver into the common bile duct which conveys it to the duodenum (the upper part of the small intestine).
Can you live without a bile duct?
If left untreated, bile duct obstructions can lead to life-threatening infections. In the long-term, they can also result in chronic liver diseases, such as biliary cirrhosis.
What is the purpose of the bile duct?
A tube that carries bile from the liver and the gallbladder through the pancreas and into the duodenum (the upper part of the small intestine). It is formed where the ducts from the liver and gallbladder are joined.
What causes bile duct problems?
The blockage is most commonly caused by gallstones or sludge impacting the bile ducts. Autoimmune disease such as primary sclerosing cholangitis may affect the system. Other, less common causes of cholangitis include: A tumor.
What is the function of liver?
Functions of the liver All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.
What does the right hepatic duct do?
Right hepatic duct: The duct that drains bile from the right half of the liver and joins the left hepatic duct to form the common hepatic duct.
How is hepatic duct formed?
When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. These ducts ultimately drain into the common hepatic duct. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct.
What happens if bile does not drain?
If something is blocking the bile duct, bile can back up into the liver. This can cause jaundice, a condition in which the skin and white of the eyes become yellow. When the bile duct is blocked, a biliary drain helps bile flow from the liver into the intestine.
What happens if your cystic duct is blocked?
If gallstones become lodged in the spiral valve or other parts of the duct, the movement of bile becomes impeded or blocked completely. Should this happen, bile will become trapped within the gallbladder. The bile will build up to the point where the gallbladder will swell.
Where is cystic duct present?
The cystic duct is the short duct that joins the gallbladder to the common hepatic duct. It usually lies next to the cystic artery. It is of variable length.
Is the cystic duct removed during a cholecystectomy?
A small incision is made just below the rib cage on the right side of the abdomen. The liver is moved to expose the gallbladder. The vessels and tubes (cystic duct and artery) to and from the gallbladder are cut and the gallbladder is removed.
What is common hepatic duct in medical terms?
Common hepatic duct: The duct formed by the junction of the right hepatic duct (which drains bile from the right half of the liver) and the left hepatic duct (which drains bile from the left half of the liver). The common hepatic duct then joins the cystic duct coming from the gallbladder to form the common bile duct.
Can bile duct tumors be benign?
A bile duct tumor is an abnormal growth that may be benign (non-cancerous) or malignant (cancerous). Most gallbladder tumors are benign, but malignant tumors may be indicative of cholangiocarcinoma (bile duct cancer).
What is the function of the left hepatic duct?
Left hepatic duct: The duct that drains bile from the left half of the liver and joins the right hepatic duct to form the common hepatic duct.
How long can you survive with a blocked bile duct?
Death from obstructive jaundice in the first few weeks of its course is quite rare and is only occasionally observed. After a period varying from four to six months, however, patients suffering from occlusion of the common bile duct usually deteriorate rapidly and die.
How serious is bile duct surgery?
Surgery for bile duct cancer is a major operation that might mean removing parts of other organs. This can have a major effect on a person’s recovery and health after the surgery. Serious problems soon after surgery can include bile leakage into the abdomen, infections, and liver failure.
How can I unclog my liver bile duct?
Some of the treatment options include a cholecystectomy and an ERCP. A cholecystectomy is the removal of the gallbladder if there are gallstones. An ERCP may be sufficient to remove small stones from the common bile duct or to place a stent inside the duct to restore bile flow.
What is hepatic bile flow?
Bile flows out of the liver through the left and right hepatic ducts, which come together to form the common hepatic duct. This duct then joins with a duct connected to the gallbladder, called the cystic duct, to form the common bile duct.
What foods should you avoid if you have no gallbladder?
People who have had gallbladder removal surgery should avoid certain foods, including:
- fatty, greasy, or fried foods.
- spicy food.
- refined sugar.
- caffeine, which is often in tea, coffee, chocolate, and energy drinks.
- alcoholic drinks, including beer, wine, and spirits.
- carbonated beverages.
What foods help bile ducts?
It stores bile produced by the liver, and releases the bile into the small intestine to help digest food. … For a healthy gallbladder, incorporate the following foods into your diet:
- bell peppers.
- citrus fruits.
- dark, leafy greens.
- tomatoes.
- milk.
- sardines.
- fish and shellfish.
- low-fat dairy.
What are the symptoms of a dilated bile duct?
symptoms of bile duct abnormalities
- Jaundice (yellowing of the skin) and/or Icterus (yellowing of the eyes). …
- Itching (not necessarily in one area and may be worse at night or warm weather).
- Urine turning orange or dark brown.
- Fatigue.
- Unexplained weight loss.
- Fever or night sweats.
Does a dilated bile duct cause pain?
Abdominal pain: This symptom of bile duct cancer usually appears in the advanced stages of the disease. Nausea and/or fever: A side effect of abnormal liver function or the buildup of bilirubin, nausea and/or fever may also result from an infection (cholangitis) caused by bile duct blockage.
Is a dilated bile duct normal?
Conclusions: CBD dilatation with normal liver chemistry is not always a benign condition. Even when prior imaging tests are negative, EUS may allow to diagnose conditions overlooked by standard diagnostic imaging.
What are the signs your liver is not functioning properly?
Signs that your liver is not functioning properly include fatigue, abdominal pain, jaundice and other symptoms and signs. The liver is a reddish-brown, cone-shaped organ found in the upper right portion of your abdominal cavity.
What are the 5 functions of the liver?

- Bile production and excretion.
- Excretion of bilirubin, cholesterol, hormones, and drugs.
- Metabolism of fats, proteins, and carbohydrates.
- Enzyme activation.
- Storage of glycogen, vitamins, and minerals.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
