Answer

Optional studies include 24-hour pH probe test and upper GI series. Use of 24-hour pH testing helps confirm the diagnosis in patients in whom the history is not clear, atypical symptoms dominate the clinical picture, or endoscopy shows no complications of reflux disease. Upper GI series can be ordered to further delineate the anatomy. Hiatal hernias can be evaluated (size) and reflux can be demonstrated. In addition, gastric emptying can be evaluated to a limited extent. If a question exists regarding inadequate gastric emptying or if the patient has a history of nausea and vomiting, a nuclear medicine gastric emptying study can be obtained.
