  • Disease

    Empyema

    The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

    Empyema is a collection of pus in the space between the lung and the inner surface of the chest wall (pleural space).

  • Test

    Esophageal culture

    A sample biopsy of esophageal tissue is obtained by placing a tube through the mouth into the esophagus where small instruments grab a portion of esophageal tissue for examination.  The test is performed when infection or other diseases of the esophagus are suspected, or an ongoing infection does not respond to treatment.

    Esophageal culture is a laboratory test that checks for infection-causing germs in a sample of tissue from the esophagus.
