The globus syndrome: value of flexible endoscopy of the upper gastrointestinal tract

Abstract

Flexible endoscopy of the upper gastrointestinal tract usually does not form part of the primary diagnostic evaluation of the globus syndrome. In a prospective trial, a flexible endoscopy was performed in 51 globus patients with normal results of the laryngologic and radiographic examination. Pathologic findings requiring therapy were diagnosed in 70.6 per cent of cases. The most frequent findings were reflux oesophagitis (n = 24; 47 per cent) and hiatal hernia (n = 25; 49 per cent). In 16 cases (31.4 per cent) these were accompanied by other pathologic lesions. A total of 32 patients (62.7 per cent) suffered from oesophageal diseases as sole aetiologic factors of the globus syndrome, which led us to postulate a causative relationship in these cases. Flexible endoscopy therefore can contribute significantly to the differential diagnosis of the globus syndrome. It must be kept in mind, however, that there is a 'blind zone' for endoscopic assessment in a region of the hypopharynx, thus some indications may require rigid endoscopy.
