Which of the following tests can be performed to diagnose a hiatal hernia?
A. Colonoscopy
B. Lower GI series
C. Barium swallow
D. Abdominal x-rays
Correct Answer: C. Barium swallow
A barium swallow with fluoroscopy shows the position of the stomach in relation to the diaphragm. A barium swallow involves drinking a special liquid, then taking X-rays to help see problems in the esophagus (such as swallowing disorders) and the stomach (such as ulcers and tumors). It also shows how big the hiatal hernia is and if there is twisting of the stomach as a result of the hernia.
Option A: A colonoscopy shows disorders of the intestine. Colonoscopy is a diagnostic as well as a therapeutic procedure performed to evaluate the large intestine (i.e., colon, rectum, and anus) as well as the distal portion of the small intestine (terminal ileum). It is performed using a hand-held flexible tube-like device called the colonoscope, which has a high definition camera mounted at the tip of the scope, as well as accessory channels that allow insertion of equipment and fluids to cleanse the colonoscope lense and colonic mucosa
Option B: A lower GI series shows disorders of the intestine. A lower GI series is a procedure in which a doctor uses X-rays and a chalky liquid called barium to view the large intestine. The barium will make the large intestine more visible on an x-ray. A lower GI series is also called a barium enema.
Option D: Abdominal x-ray uses a very small dose of ionizing radiation to produce pictures of the inside of the abdominal cavity. It is used to evaluate the stomach, liver, intestines, and spleen and may be used to help diagnose unexplained pain, nausea, or vomiting.
