What Is the Hepatobiliary System?
At Advanced Laparoscopic Associates, our surgeons specialize in the treatment of conditions of the abdominal cavity, including the hepatobiliary system.
The hepatobiliary tract consists of the liver, gallbladder and bile ducts. This system serves to remove waste products from the liver into the duodenum (first section of small intestine) and helps digestion by controlled release of bile. Bile is a greenish-yellow fluid secreted by the liver cells that contains cholesterol and bile salts.
Bile breaks down fats during the digestive process and carries away waste. Half of all bile runs directly into the duodenum while the other half is stored in the gallbladder. When food is eaten, the gallbladder releases the stored bile into the duodenum to help break down the fats.
Most of the released bile (90 percent) is reabsorbed in the intestinal tract. A small percentage of bile is eventually excreted in the form of feces and is the component that gives feces their dark brown color.
What Are Gallstones?
When the hepatobiliary system is functioning normally, the liver, gallbladder and hepatic ducts work together to produce, secrete, transport and store bile. However, many dysfunctions of this system may occur. Gallstones are one of the primary dysfunctions of the hepatobiliary system.
Gallstones are deposits of digestive fluid (bile) that has hardened into “stones” that range from the size of a grain of sand to a golf ball. There are two kinds of gallstones, depending on their content – cholesterol (most common) and pigment.
Cholesterol stones form when the gallbladder doesn’t empty properly and also when bile contains too much cholesterol and bilirubin. Pigment stones form when cells breakdown from a range of disease.
People may develop one or more gallstones at the same time. If gallstones have no symptoms, surgery is usually not required. However, if they are causing a blockage, inflammation or pain, surgery is generally indicated.
Forms of Hepatobiliary Surgery
At Advanced Laparoscopic Associates, we perform the following surgical procedures to treat hepatobiliary conditions:
Cholecystectomy is the surgical removal of the gallbladder. This surgery is very common and low risk. Gallbladder removal may be required if gallstones have formed and are blocking the flow of bile. Blockages can cause pain, inflammation and even cancer. Indications include gallstones in the gallbladder or bile ducts and gallbladder or pancreatic inflammation (pancreatitis).
A cholecystectomy is usually performed minimally invasively, either laparoscopically or robotically. Rarely will we need to perform an open procedure to remove a gallbladder.
In a minimally invasive procedure, four small incisions are made in the abdomen. A tiny camera is inserted for the surgeon to visualize the abdominal cavity, and the gallbladder is removed. This surgery is most often done as an outpatient procedure and patients may go home the same day.
Because the gallbladder merely concentrates and stores bile already made in the liver, the body will be able to function normally without the gallbladder. Without a gallbladder, the liver releases bile directly into the intestines. Bile directly from the liver is less concentrated and therefore slightly less effective at breaking down fatty foods, but the body can adapt without a gallbladder.
Common Bile Duct Exploration
This procedure is used to see if the flow of bile from the liver and gallbladder to the intestine is being blocked. If something, such as a stone, is blocking the bile duct, bile can back up into the liver. This blockage can cause jaundice (yellowing of the skin and eyes) or infection of the bile duct.
A cholagiogram—a picture of the bile ducts—is usually performed at the time of a cholecystectomy. Dye is injected into the bile duct. An X-ray is taken to show the blockage location.
If stones are found, a choledocchoscopy can be performed. A choledochoscopy is a procedure performed under general anesthesia. It is a visual exploration of the inside of the common bile duct using a small endoscope (choledochoscope).
The endoscope can be inserted intraoperatively through the cystic duct, directly into the common bile duct. Small calculi (stones) may be removed if found during this procedure.
In more complicated cases a tube may be inserted into the bile duct in order to drain bile into a bag outside the body for one to several weeks. An X-ray procedure may need to be repeated before tube removal. A hospital stay of one to four days may be required.
A liver ultrasound (or abdominal ultrasound) is a short, noninvasive imaging test that may be performed in conjunction with other imaging tests. This test uses sound waves to produce images of the size and shape of the liver, as well as blood flow through the liver. Liver ultrasounds are indicated when fatty liver disease (FLD), cirrhosis of the liver, liver fibrosis or other liver abnormalities are suspected.
In FLD, normal liver tissue is replaced by more than five to six percent fat, which can cause:
- Cell death
- Scarring of the liver
Without treatment, FLD can lead to liver fibrosis, which can reduce blood flow through the liver and create scar tissue. Liver fibrosis may cause cirrhosis, liver cancer or liver failure. On a liver ultrasound, scarred livers look brighter than normal livers, while cirrhotic livers look shrunken and lumpy.
Ultrasound elastography is an imaging technique to check for liver fibrosis. Through the movements of the liver caused by the ultrasound waves, doctors may measure the liver’s elasticity (or stiffness). Fibrotic livers are much less elastic than normal livers and move much more in response to the ultrasound waves.
In this procedure, a small piece of liver tissue is removed to examine for signs of disease or damage. A liver biopsy is often recommended when blood tests or imaging studies indicate a possible liver problem, such as a liver tumor or ongoing fevers of unknown origin.
Liver biopsies are also used to determine the severity of liver disease (staging), including:
- Hepatitis B or C
- Wilson disease
- Alcoholic liver disease
- Nonalcoholic fatty liver disease
- Autoimmune hepatitis
A percutaneous liver biopsy is the most common type performed. A thin needle is inserted through the abdomen into the liver to remove a small piece of tissue. There are two other types of liver biopsies – transjugular (through a vein in the neck) and laparoscopic (through a small incision in the abdomen).
If you are experiencing abdominal pain and suspect you may have gallstones or another biliary tract dysfunction, please contact us today for an appointment. If you are experiencing severe abdominal pain, this is a medical emergency and you should seek immediate medical attention.
For additional information, all prospective patients are invited to attend a free educational seminar.
Seminars are a great source of information about the procedure you are considering, and they allow you to meet the surgeons as well as ask any questions you may have. You may also have the opportunity to meet some post-operative patients.
