Esophageal biopsy culture

Alternative names:

culture of esophageal biopsy

How the test is performed:

A sample of esophageal tissue is placed on culture media in containers for the purpose of growing microorganisms (bacteria, fungus, or viruses) in the laboratory which will later be identified under the microscope. The microbiologist in the laboratory inspects the cultures daily for growth. If microorganisms are detected, other tests may be initiated to determine the sensitivity of the organisms to medications. Definitive antimicrobial therapy can then be determined based on these results.

How to prepare for the test:

The sample of tissue is usually obtained by EGD (esophagogastroduodenoscopy), a scope which 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.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

The large tube placed down your mouth and throat, is used to view the esophagus and take the biopsy. However, your are given sedatives, analgesics, 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 allowed after the gag reflex returns to prevent choking.

Why the test is performed:

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.
