Esophageal manometry examines the function of the esophagus and its muscle contractions during swallowing. For patients experiencing swallowing difficulties, after endoscopic evaluations rule out tumors or significant reflux, diagnoses such as achalasia are confirmed using manometric methods. These comprehensive manometric studies are successfully performed at the Motility Center, located within Memorial Bahçelievler Hospital's newly opened Advanced Endoscopy Center.
