First page of Role of endoscopy in achalasia

Background: Esophagogastroduodenoscopy is often performed as an initial examination in patients with symptoms such as dysphagia or chest pain, which may suggest esophageal motility disorders. However, its current role is largely limited to ruling out organic diseases. Summary: High-resolution manometry (the gold standard for diagnosing primary esophageal motility disorders such as achalasia) along with esophagography is extremely useful for diagnosis. In recent years, however, several new endoscopic findings—esophageal rosette, gingko leaf sign, champagne glass sign, corona appearance, and pinstripe pattern—have been reported, making it increasingly possible to strongly suspect achalasia through endoscopy. Additionally, the presence of multiple annular contractions, spiral (corkscrew) contractions, or narrowing (poor distensibility) in the esophageal body during endoscopy may suggest abnormal motility of the esophageal body. Key Messages: When performing endoscopic examinations in patients with symptoms such as dysphagia or chest pain, it is important to consider the possibility of esophageal motility disorders. Careful endoscopic observation may allow for the suspicion of such disorders during the examination itself.
