Dysphagia is frequent and underdiagnosed, particularly in the elderly population. It can be of oropharyngeal or esophageal origin. One should not await weight loss to start investigations. Management is multidisciplinary. Complementary examinations will depend on the type of dysphagia. Digestive endoscopy plays an important role for both the diagnosis and treatment of many esophageal conditions. Peroral endoscopic myotomy (POEM), for example, is a still recent technique that has allowed progress in the minimally invasive management of achalasia.
