Mandatory studies include upper GI endoscopy and manometry. Endoscopy can help confirm the diagnosis of reflux by demonstrating complications of reflux (esophagitis, strictures, Barrett esophagus) and can help in evaluating the anatomy (eg, hiatal hernia, masses, strictures). Manometry helps surgical planning by determining the lower esophageal sphincter (LES) pressure and identifying any esophageal motility disorders. Esophageal amplitudes and propagation of esophageal swallows are also evaluated.
