Culture - esophageal biopsyDefinition Return to top
Esophageal biopsy culture is a laboratory test to identify organisms causing infection from a specimen obtained by a biopsy of the esophagus.How the test is performed Return to top
A sample of esophageal tissue is placed on culture media for the purpose of growing microorganisms (bacteria, fungus, or viruses) in the laboratory which will later be identified.
A microbiologist in the laboratory inspects the cultures daily for growth. If microorganisms are detected, other tests may be done to determine the sensitivity of the organisms to medications. The best antimicrobial therapy can often be determined based on these results.
How to prepare for the test Return to top
The sample of tissue is usually obtained by EGD (esophagogastroduodenoscopy), a procedure in which a scope is passed into the esophagus. Fast for at least 6 hours before the test. Remove all jewelry. You will wear a hospital gown. The test may be performed in a specialist's office or special procedures area of an outpatient facility or hospital.How the test will feel Return to top
The large tube placed down your mouth and throat is used to view the esophagus and take the biopsy. You are given sedatives, analgesics (pain relievers), and muscle relaxants before the procedure to eliminate much of the discomfort.
You are relaxed, but awake enough to cooperate with instructions. The specimen is obtained through the scope with special instruments. The tube is then removed. Some numbness remains until the anesthetic wears off, then sore throat may be noticed for 1 or 2 days. Food and fluid are not allowed until after the gag reflex returns to prevent choking.
Why the test is performed Return to top
The test is performed when infection of the esophagus is suspected, an ongoing infection does not respond to treatment, other disease of the esophagus or gastrointestinal tract is suspected or present, or unidentified infection is present.Normal Values Return to top
No organisms on the culture after an appropriate growth period is normal.What abnormal results mean Return to top
Abnormal results indicate an infection of the esophagus. The infection may be bacterial, viral, or fungal. The causative organism and an effective medication to treat the organism, if available, may be indicated in the results.What the risks are Return to top
The risks are related to the procedure of EGD and are mainly discomfort. A small risk of bleeding or infection is also present.Special considerations Return to top
Other endoscopic procedures or tests may be performed in conjunction with an esophageal biopsy culture. Update Date: 1/26/2004 Updated by: Daniel Levy, M.D., Ph.D., Infectious Diseases, Greater Baltimore Medical Center, Baltimore, MD. Review provided by VeriMed Healthcare Network.
