    Abstract:
    Nonpropulsive esophageal contractions radiologically described as tertiary contractions or "corkscrew" esophagus suggest the presence of an underlying motility disorder and may lead to impaired acid clearance. The goals of this study were to determine the prevalence and role of gastroesophageal reflux (GER) in patients with tertiary contractions. Thirty-five consecutive patients with spontaneous, repetitive, nonpropulsive esophageal contractions noted on esophagography were studied with endoscopy, infusion esophageal manometry, and 24-h ambulatory pH monitoring. All patients had esophageal symptoms, mainly dysphagia, heartburn, and chest pain, but only three were found to have esophagitis by endoscopy and biopsy. Nineteen patients had repetitive, nonlumen-obliterating, nonperistaltic (tertiary) contractions, six had corkscrew esophagus, and 10 had forceful, lumen-obliterating simultaneous contractions (rosary bead esophagus). Twenty patients (58%) had GER by pH criteria with mean values: % time pH less than 4, 40.9; %upright pH less than 4, 41; %supine pH less than 4, 44.3%; number of episodes with greater than 5 min of pH less than 4, 12. Esophageal motility revealed "nutcracker" esophagus in eight, low LESP in two, and nonspecific esophageal motility disorder in 10. Symptoms or severity of nonperistaltic contractions did not correlate with GER. Radiologically demonstrable free reflux or the presence of heartburn did not predict GER. We conclude that 1) GER occurs in up to 58% of patients with nonpropulsive (tertiary) esophageal contractions on esophagography, and may play a role in the induction of abnormal peristaltic activity of the esophageal body; 2) GER is usually not associated with endoscopic evidence of esophagitis or characteristic symptoms, and is recognized by 24-h pH monitoring. We speculate that detection and treatment of GER may improve the symptomatic management of patients with nonpropulsive esophageal contractions.
