Functional lumen imaging probe and Heller myotomy: solves the dysphagia issue, but the resulting GERD is still a mystery

The practice of esophagology has advanced significantly over the past few decades as the now widespread use of high-resolution esophageal manometry (HRM), 24-hour pH-impedance testing, and 48- to 96-hour wireless pH monitoring have transformed the way in which we evaluate patients with esophageal diseases.
