Many people who have gallstones will experience no symptoms. However, if the gallstones are blocking a bile duct, symptoms can occur. People who experience prolonged pain that lasts for more than five hours, nausea and vomiting, fever, chills, yellowish skin or yellow discoloration of the whites of the eyes, or clay-colored stools may be experiencing a gallbladder attack. These attacks can sometimes follow fatty meals or happen at night. Anyone experiencing these symptoms should see a doctor immediately as these can be an indication of a large gallstone or other condition.
A biopsy is a sample of tissue removed by your doctor to make a precise diagnosis. Biopsy procedures can range from a simple sampling of skin under local anesthesia to surgical opening of the chest wall to remove a portion of lung tissue. Biopsies may also be obtained during diagnostic procedures such as endoscopy, colonoscopy, bronchoscopy, and others. Sometimes doctors perform biopsies using a CAT scan or other radiological imaging techniques to help identify the exact area to be sampled and avoid injury to surrounding organs. There are several types of biopsies.
