What is cholecystitis?
Cholecystitis is a redness and swelling (inflammation) of the gallbladder. It happens when a digestive juice called bile gets trapped in your gallbladder.
The gallbladder is a small organ under your liver. It stores bile which is made in the liver.
Normally bile drains out of your gallbladder and into your small intestine. If the bile is blocked, it builds up in your gallbladder. This causes inflammation and can cause infection.
Cholecystitis can be sudden (acute) or long-term (chronic).
What causes cholecystitis?
The gallbladder stores a digestive juice called bile. Little stones called gallstones can form in your gallbladder. They are made from bile. Cholecystitis happens when bile gets trapped in your gallbladder.
In most cases, this happens because gallstones are blocking a tube that drains bile from the gallbladder. This causes bile to build up in your gallbladder causing irritation and pressure. It can cause swelling and infection.
Other causes of cholecystitis include:
Bacterial infection in the bile duct system. The bile duct system is the drainage system that carries bile from your liver and gallbladder into the first part of your small intestine (the duodenum).
Tumors of the pancreas or liver. A tumor can stop bile from draining out of your gallbladder.
Reduced blood supply to the gallbladder. This may happen if you have diabetes or, occasionally, if you are very sick from other causes and staying in the hospital ICU..
Gallbladder sludge. This is a thick material that can?t be absorbed by bile in your gallbladder. The sludge builds up in your gallbladder. It happens mainly to pregnant women or to people who have had a very fast weight loss.
Cholecystitis can happen suddenly (acute) or it can be long-term (chronic).
What are the symptoms of cholecystitis?
In most cases, an attack of cholecystitis lasts 2 to 3 days. Each person?s symptoms may vary. Symptoms may include:
Intense, sudden pain in the upper right or center part of your belly
Pain (often worse with deep breaths) that spreads to your back or below the right shoulder blade
Yellowing of the skin and eyes (jaundice)
Loose, light-colored bowel movements
The symptoms of cholecystitis may look like other health problems. Always see your healthcare provider to be sure.
How is cholecystitis diagnosed?
Your healthcare provider will look at your past health and give you a physical exam.
You may also have some blood tests including:
Complete blood count (CBC). This test measures your white blood cell count. You may have a high white blood cell count if you have an infection.
Liver function tests. A group of special blood tests that can tell if your liver is working properly.
You may also have imaging tests, including:
Ultrasound. This test creates images of your internal organs on a computer screen using high-frequency sound waves. It is used to see the liver and gallbladder and check blood flow through different vessels.
Belly X-ray. This test makes pictures of internal tissues, bones, and organs using invisible electromagnetic energy beams.
CT scan. This is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs. It is more detailed than a regular X-ray.
HIDA scan (cholescintigraphy or hepatobiliary scintigraphy). This scan checks for any abnormal movements (contractions) of your gallbladder. It also checks for blocked bile ducts. A radioactive chemical or tracer is shot (injected) into your vein. It collects in your liver and flows into your gallbladder. A special scanner watches the tracer move through your organs. You will take medicine to make your gallbladder contract.
PTC (percutaneous transhepatic cholangiography). A thin needle is put through your skin and into the bile duct in your liver. A dye is then shot (injected) through the needle. The dye lets your bile ducts be seen clearly on the X-rays. A blocked duct will show up on the X-rays.
ERCP (endoscopic retrograde cholangiopancreatography). This is used to find and treat problems in your liver, gallbladder, bile ducts, and pancreas. It uses X-ray and a long, flexible tube (endoscope) with a light and camera at one end. The tube is put into your mouth and throat. It goes down your food pipe (esophagus), through your stomach, and into the first part of your small intestine (the duodenum). It then goes into your bile ducts. The inside of these organs can be seen on a video screen. A dye is put into your bile ducts through the tube. The dye lets the bile ducts be seen clearly on the X-rays.
MRCP (magnetic resonance cholangiopancreatography). This is a special MRI test that gives details about the liver, pancreas, gallbladder, and bile drainage area.
How is cholecystitis treated?
You will likely be admitted to a hospital to rest your gallbladder. You may need surgery to remove your gallbladder.
In the hospital your treatment may include:
Taking antibiotic medicines to fight the infection
Taking fluids and pain medicines by IV
Keeping your stomach empty until your symptoms ease
Your symptoms may get better with this treatment. But if your cholecystitis is caused by gallstones in your gallbladder, you will need to have surgery to remove your gallbladder. Gallbladder removal (cholecystectomy) is a common surgery. Your body will work well without your gallbladder. It is not essential for a healthy life.
You may have surgery done right away. If you are too sick to have surgery, a small tube may be put through your skin and into your gallbladder. This will drain the bile and ease your symptoms until you can have surgery.
Other treatment options may include:
Oral dissolution therapy. Medicines made from bile acid are used to dissolve the stones. It only works for some types of gallstones. The gallstones often come back when the medicine is stopped.
Medicines. These are used to prevent gallstones from forming.
Low-fat diet. When you are allowed to eat food again,you should keep to a low-fat diet.
What are possible complications of cholecystitis?
In some cases, cholecystitis can cause other problems including:
Infection and pus buildup in your gallbladder
Tissue death in your gallbladder (gangrene)
Bile duct injury that can affect your liver
Infection and inflammation of your pancreas (pancreatitis)
Infection and inflammation of the lining of your belly (peritonitis)
If your gallbladder has not been removed and you have more attacks of cholecystitis, you may develop long-term (chronic) cholecystitis.
Chronic cholecystitis may not cause any symptoms. But it can damage the walls of your gallbladder. The walls can become scarred and get thicker. Your gallbladder will start to get smaller. Over time, it will be less able to store and release bile. You will need surgery to remove your gallbladder.
When should I call my healthcare provider?
Call your healthcare provider right away if:
You have severe belly pain that won?t go away
Your cholecystitis symptoms come back after treatment
Key points about cholecystitis
