CLINICAL AND MANOMETRIC ASPECTS OF DIFFUSE ESOPHAGEAL SPASM IN A COHORT OF SUBJECTS EVALUATED FOR DYSPHAGIA AND OR CHEST PAIN

Manometric criteria for diffuse esophageal spasm have recently been restated. In this study, a cohort of 358 subjects was evaluated in a gastrointestinal motility laboratory for dysphagia and/or chest pain. Applying the recently proposed criteria of Richter and Castell, 18 subjects (5%) were diagnosed as having DES. Dysphagia was the major complaint (89%), while 44% of patients complained of chest pain and 33% of both symptoms. All patients shared more than 30% simultaneous contractions after wet swallows interspersed with normal peristaltic sequences. Associated manometric findings were repetitive (>3 peaks) contractions (67%), high-amplitude contractions (33%), spontaneous activity (22%), prolonged duration (11%), and lower esophageal sphincter abnormalities (5%). Radiology discosed significant abnormalities in only 27% of DES patients.
