Hiatal Hernia and Pulmonary Involvement

Prior to subject's surgical procedure, blood (about 3 tablespoons (44 mL)) will be collected through a needle in vein for research purposes. The UVA researchers will analyze the biomarkers that are expressed in subject's blood.

Following blood collection, the subject will undergo the bronchoscopy for research purposes. While in the operating room, a bronchoscope will be inserted through the breathing tube that is already been placed for the surgery. Subject's airways will be examined with the bronchoscope in both lungs. Ten tablespoons (150 mL) of saline solution will be injected into one of subject airways. The fluid will be re-collected by suctioning it back up with the bronchoscope. The fluid will be collected from the bronchscope.
