How Are Gallstones Diagnosed?Thursday, March 22, 2012 - 16:00
Accurate diagnosis is very important because gallstone symptoms are similar to those of several serious diseases.
They include heart attacks, ulcers, appendicitis, pancreatitis, hiatal hernia, and hepatitis.
Doctors may suspect gallstones based on a person's symptoms, especially in someone who is at high risk for gallbladder disease. A simple physical examination in the doctor's office may also suggest gallbladder disease. The doctor, for instance, usually presses gently with his fingers just below the ribs on the right side of the chest. That area often is tender in people with gallbladder disease. Blood tests also can show signs of obstructed ducts.
The sound waves bounce off the gallbladder,
An ultrasound scan can provide a great deal of information about a person's condition by:
- Confirming whether gallstones are present
- Showing how many stones are present, and their size
- Seeing whether the stones are in the gallbladder or the ducts
- Are painless
- Do not involve x-rays or use of radioactive materials
- Have no known damaging effects on the body
- Can be repeated safely as many times as needed

An oral cholecystogram (OCG) or cholescintigraphy involves receiving an injection of an iodine x-ray dye into a vein, or taking iodine pills. X-rays then are taken of the gallbladder to see whether it contracts normally or stones are present.
Diagnosing Stones In The Common Bile Duct
Diagnosing stones that have passed into the
- ERCP (Endoscopic retrograde cholangiopancreatography)involves swallowing a thin, flexible tube, or
endoscope, that the doctor gently moves through the gastrointestinal tract to the small intestine. He releases a special dye into the small intestine, and it stains the gallbladder's ducts. Any stones present in the ducts then can be seen on an x-ray.
- PTC (Percutaneous transhepatic cholangiography) involves injecting x-ray dye into the bile ducts with a needle that is passed through the liver.
Nice To Know:
Q. I had an ultrasound scan of the abdomen for another medical problem. It showed several big stones in my gallbladder. Should I have my gallbladder removed?
A. About 60% of people with gallstones never have any symptoms and never get sick. They're just like you. Most might never even know they had gallstones. Their stones are discovered by accident, during tests for other diseases. If you do start having abdominal pain after fatty meals, indigestion, gas, bloating, or other symptoms, make sure to remind the doctor about the ultrasound scan results.
