Update on the endoscopic treatments for achalasia

Figure 2 High-resolution esophageal manometry of a patient with achalasia. A 34-year-old man with progressive dysphagia to liquids and solids had a barium esophagram suggestive of achalasia. He presented for high-resolution manometry to confirm the diagnosis of achalasia. The manometric and topographic findings demonstrated aperistalsis with residual pressure at the lower esophageal sphincter with an elevated integrated relaxation pressure and pan-esophageal pressurization, which was consistent with type II achalasia by the Chicago classification.
