OBJECTIVE: To describe the manometric findings detected in adult patients with dysphagia that were diagnosed of eosinophilic oesophagitis, and to compare with the cases of eosinophilic infiltration of the oesophagus reported in the literature. PATIENTS AND METHODS: We present 12 adult patients diagnosed as suffering from this disorder in our department in a 1.5-year period, according to histological criteria and discarding any other cause of eosinophilic infiltration of the oesophagus. Stationary oesophageal manometry using a hydropneumocapillary perfusion system was performed in every case. The recommendations of the Spanish Group of Digestive Motility were followed for the interpretation of the results. In seven patients who presented motor disorder in manometric evaluation, treatment with steroid oesophageal lavage using fluticasone propionate was carried out and these patients were subsequently re-evaluated. RESULTS: All patients were young predominantly men, and the first endoscopic examination showed regular concentric stenosis or a 'ring oesophagus'. Six patients had a severe nonspecific oesophageal motor disorder characterized by up to 80% of nontransmitted or very low-amplitude waves in the lower two-thirds of the organ. Three patients presented a manometric disturbance characterized by hyperkinetic peristaltic waves in distal oesophageal third. One patient had an alteration of the oesophageal motor dynamics characterized by 80% of deglutory complexes formed by a primary simultaneous wave in the two lower oesophageal thirds followed by a secondary peristaltic wave in 50% of cases that had a normal duration and amplitude. The remaining two patients had normal oesophageal motility. The upper oesophageal sphincter showed no alterations, and the manometric evaluation of the lower oesophageal sphincter tone proved normal in 10 patients, with slight hypotension in two cases. In seven of the nine patients who presented an oesophageal motor disorder, treatment with steroid oesophageal lavage using fluticasone propionate was administered and a new oesophageal manometry was performed afterwards, in which the motor disorder was clearly improved as soon as dysphagia, endoscopic lesions and histopathologic alteration disappeared. DISCUSSION: In the literature, 61 cases of eosinophilic infiltration of the oesophageal mucosa subjected to oesophageal manometric study had been described, and 60.6% of them showed evidence of different types of manometric alterations, mainly with spastic or hypercontractility characteristics. Although six of our cases showed very deficient peristalsis with very low-amplitude or nontransmitted waves, and in another three high-amplitude peristaltic waves were recorded. Motor disorders improved parallel to the disappearance of the eosinophilic infiltration of the mucosa. These data suggest that motor disorders in eosinophilic oesophagitis are a consequence of eosinophil infiltration of the oesophagus and should be considered in the differential diagnosis of dysphagia. These manometric alterations could be considered as primary nonspecific disorders and included in the 'ineffective oesophageal motility' group.
