Gallstones are also a common gallbladder problem, and infection can occur if the gallbladder remains blocked by a gallstone or continues to be inflamed. Gallbladder disease is the term used to describe many of these maladies that can plague the gallbladder. But in many forms of gallbladder disease, a person may have no symptoms — up to 90 percent of people with gallstones, for example, don’t have any symptoms at all. So how can gallbladder disease be diagnosed? Gallbladder Disease: When Diagnostic Tests Are Needed Your doctor isn’t going to test you for something that you’re not complaining about, so generally, the only time diagnostic tests for gallbladder problems are done is when a person experiences symptoms. Warning signs of gallbladder problems include:
Bouts of severe pain in the right upper abdomen and sometimes the right chest or backPain after eating, particularly high-fat foods, or at nightFever, with shaking and chills, especially if occurring with, or after, abdominal painNausea and perhaps vomitingHeartburn and indigestionA feeling of fullness in the abdomen, or excess gas
If you don’t have symptoms, that doesn’t mean your gallbladder is perfectly normal. Often, doctors will spot signs of gallbladder problems during diagnostic testing for some other symptom or health condition. Gallbladder Disease: Eliminating Other Causes If you have some combination of these symptoms, your doctor probably will start by asking detailed questions about them. He may ask for more details about the pain — what it feels like, when it happens, and where in your belly it hurts. Your doctor will also ask questions to look for other possible causes of abdominal pain, like:
Irritable bowel syndrome (IBS)Crohn’s disease or ulcerative colitisCancer or inflammation of the pancreasKidney stones or urinary tract infectionsPneumonia (when it involves the lower part of the right lung, it can be confused with gallbladder discomfort)Viral hepatitisAppendicitisGastroesophageal reflux or ulcers in the stomachDiverticulitis or diverticulosis — conditions affecting the lining of the colon
Gallbladder Disease: Diagnostic Imaging Tests After asking questions about your symptoms, doing a physical exam, and eliminating some causes from the list of possibilities, your doctor probably will perform some imaging tests to look at your gallbladder. Imaging tests used to diagnose gallbladder problems include:
An ultrasound. This is the most commonly used of the diagnostic tests for gallbladder problems. While very effective in diagnosing even very small gallstones, it can’t always clearly diagnose cholecystitis (inflammation of the gallbladder).X-rays. An abdominal X-ray can spot gas and some types of gallstones containing calcium. Some X-ray types require that a patient swallow a dye or have dye injected into the body so the X-ray can capture a clearer picture of the gallbladder.Computed tomography (CT) scan. This imaging test uses a computer and X-rays to spot gallbladder problems, but isn’t the most effective method of diagnosing gallstones. CT scans can help spot ruptures (tears in the gallbladder wall) and infections inside the gallbladder or its bile ducts.Magnetic resonance imaging (MRI) . Regular MRI, or another type called magnetic resonance cholangiography (MRC), can help diagnose stones in the bile ducts. MRC uses regular MRI imaging technology plus a dye administered into the bile duct. This test is very useful for diagnosing biliary tract (gallbladder and surrounding ducts) cancer, but may not be able to spot tiny stones or persistent infections.Endoscopic retrograde cholangiopancreatography (ERCP) . This test uses an endoscope (a tube fitted with a tiny camera and light) that is inserted into the throat, down through the stomach, and into the small intestine. This test can help spot gallstones or problems in the bile ducts of the gallbladder — it’s considered the “gold standard” when it comes to diagnosing stones blocking bile ducts, and allows for removal (using a small basket-like device) during the test. But there is a risk of complications, so the test is typically only given to people who are thought to be very likely to have stones blocking the bile ducts.Cholescintigraphy (also called DISIDA, HIDA scan, or gallbladder radionuclide scan). A small amount of radioactive dye is administered, and then a scanning device is used to track the dye as it moves into the gallbladder. This screening method can spot a blocked duct and acute inflammation, but not chronic gallbladder inflammation or gallstones.
Gallbladder Disease: Blood and Urine Tests A blood test may also be performed to help diagnose gallbladder disease. A complete blood count, or CBC, can help confirm an infection if there is a high white blood cell count. Other specific blood tests can also reveal high bilirubin levels (the cause of jaundice, a complication of gallbladder problems) or elevated enzymes suggesting an obstruction in the gallbladder. Urine tests may also be performed to help diagnose problems with the gallbladder by looking for abnormal levels of chemicals like amylase, which is an enzyme that aids in the digestion of carbohydrates, and lipase, another enzyme that helps break down fats. Even if signs and symptoms are not directly suggesting gallbladder disease, your doctor has many ways to visualize the gallbladder. With these tests, your gallbladder disease can usually be promptly diagnosed — and just as importantly, properly treated.
