    Abstract:
    BACKGROUND/PURPOSE: This report identifies a group of children in whom severe acute food bolus impaction (AFBI) was the leading symptom of gastroesophageal reflux (GER) in the absence of stricture. METHODS: The esophageal structure and function of 8 patients treated for AFBI requiring endoscopic removal of alimentary foreign bodies in 6 of them (up to 4 times in 1 case) were investigated by barium meal, esophagoscopy-biopsy, pH-metering, pull-through stationary manometry, and 24-hour ambulatory manometry. The results were compared with those in a group of age-matched regular refluxers (n = 14) without AFBI. RESULTS: Six boys and 2 girls aged 108 +/- 59 months had impaction. Six children had symptoms of GER like vomiting during infancy, heartburn, or respiratory tract disease. Barium swallow ruled out stenosis in all patients and showed small hiatal hernias in 3. All had endoscopic and histologic esophagitis (moderate to severe in 6), and one had Schatzki ring. All but one (who had 8.45 mm Hg) had normal lower esophageal sphincter pressure (16.2 +/- 4.7 mm Hg, mean +/- SD), and all showed normal sphincteric relaxation. Esophageal body motility was not significantly different from that in regular refluxers except in 6 children in whom energetic distal peristalsis after reflux episodes could be seen particularly during the night. Three of them had amazingly powerful distal waves during the day and even stronger, simultaneous, wide and bizarre-shaped waves during sleep. Symptoms improved in all cases after antireflux medication. Four patients were cured after antireflux surgery. CONCLUSIONS: AFBI is a dramatic but practically unheard of symptom of GER in children. It should be differentiated from dysphagia and reveals motor dysfunction, sometimes severe, of the esophageal body in the absence of sphincteric obstruction. Antireflux medication or surgery were uniformly successful in our patients.
