To investigate the frequency and severity of esophagitis and esophageal dysmotility in patients with chronic spinal cord injury (SCI), 46 males with chronic SCI completed a questionnaire regarding gastrointestinal symptomatology. Eleven of these patients subsequently underwent upper gastrointestinal (GI) endoscopy with esophageal biopsies and 10 of the 11 also had esophageal motility studies. A significantly higher percentage of SCI patients experienced heartburn (SCI 61%; controls (C) 40%), esophageal chest pain (SCI 33%; C 6.4%), and intermittent dysphagia (SCI 30%; C 8.5%). Forty-five percent of SCI patients had endoscopic evidence of mild esophagitis, and 91% of them had histologic evidence of esophagitis. SCI patients had low amplitude, slowly propagating abnormal (double-peaked) peristatic esophageal contractions. We conclude that SCI patients experience significantly more esophageal symptoms than controls. They have a higher incidence of esophagitis and esophageal motor abnormalities. The clinical relevance of these abnormalities remains to be evaluated.
