Assessment of Post-traumatic Stress Disorder Among Objective Esophageal Motility and Reflux Phenotypes in Symptomatic Veterans.

Prior research suggests post-traumatic stress disorder (PTSD) is associated with the development of esophageal symptoms. We aimed to evaluate the prevalence of PTSD in veterans with esophageal symptoms, and assess for differences in objective esophageal motility and reflux classifications. Consecutive veterans reporting esophageal symptoms (e.g., dysphagia and reflux) underwent clinical evaluation with standard reflux and motility testing. Relevant demographic, mental health, and clinical esophageal information was gathered. Patients were classified into "PTSD" and "Non-PTSD" groups based on the documentation of a clinician-confirmed diagnosis of PTSD in the medical chart. Of the 273 consecutive veterans (89% men, mean age: 62 years) that met inclusion criteria for the study, 34% had a clinician-confirmed diagnosis of PTSD. Differences existed between PTSD and non-PTSD groups on smoking, bipolar disorder, depression, ADHD, and opiate use. However, no differences existed in objectively determined motility or reflux phenotypes. While PTSD was highly prevalent among our sample of symptomatic veterans, the presence of PTSD was not associated with differences in motility classifications and reflux phenotypes. These findings are consistent with recent research in psychogastroenterology, which suggests psychological processes are important to consider across esophageal classifications.
