Patient care diagnostic tests, tools, procedures
Gallbladder endoscopy: An endoscope is a device consisting of a flexible tube and an optical system. In endoscopy, this device is introduced through the mouth or anus to view the interior of the body.
How the test is performed: Endoscopes used to look directly at the outside of the uterus, Fallopian tubes, ovaries, appendix, and other abdominal organs have the special name laparoscope (see laparoscopy). Other endoscopes are inserted through incisions to look at joints (arthroscopy), and still others to view the inside of the bladder (cystoscopy).
An endoscope, a flexible fiberoptic scope with a light, is inserted through the mouth into the duodenum. A catheter is advanced through the endoscope and inserted into the pancreatic or biliary ducts. A contrast agent is injected into these ducts and X-rays are taken to evaluate their caliber, length and course. Endoscopic retrograde cholangiopancreatography (ERCP) is performed to identify any narrowing, stones, or tumors in the pancreatic or biliary ducts.
The gallbladder is a muscular sac located under the liver. It stores and concentrates the bile produced in the liver that is not immediately needed for digestion. Bile is released from the gallbladder into the small intestine in response to food. The pancreatic duct joins the common bile duct at the small intestine adding enzymes to aid in digestion.
