Mandatory studies for GERD include upper gastrointestinal (GI) endoscopy and manometry. Manometry helps surgical planning by identifying any esophageal motility disorders and determining the lower esophageal sphincter pressure. It also allows the clinician to evaluate the amplitudes and propagation of esophageal swallows.
Upper GI series and nuclear medicine gastric emptying studies are optional. Upper GI series can delineate the anatomy, offering limited insight into gastric emptying, demonstrate reflux, and evaluate the size of hiatal hernias. A nuclear medicine gastric emptying study can help answer questions about inadequate gastric emptying and assist with patients who have a history of nausea and vomiting. It is routine to obtain manometry in the workup for GERD; however, upper GI series and nuclear medicine gastric emptying studies are ordered only if clinically indicated. Ultrasonography and CT are not part of the routine evaluation of patients with GERD.
