Esophagogastric Junction Outflow Obstruction Association With Mood Disorders: A Retrospective Study: 2853
AMERICAN JOURNAL OF GASTROENTEROLOGY(2019)
Abstract
INTRODUCTION: Esophagogastric Junction Outflow Obstruction (EGJOO) is a manometry abnormality at the level of the lower esophageal sphincter (LES) which is associated with elevated Integrated Relaxation Pressure (IRP). This is similar to achalasia; however, EGJOO has retained peristalsis and it is largely distinguished by poor relaxation at the LES. This diagnosis is becoming increasingly prevalent as use of esophageal High-Resolution Manometry (HRM) becomes more widespread. As EGJOO’s prevalence grows, it is important to augment our knowledge. Our objective from this analysis was to find comorbid associations which may give aide in identifying at risk patients and aide with treatment modalities. Depression and anxiety were focused upon in this study. METHODS: We performed a retrospective study of patients who were diagnosed with EGJOO by HRM from 2015 to 2018 at a single tertiary care center. Patients were classified as having EGJOO by the Chicago Classification (version 3). Chart review was performed to assess for comorbid conditions. Statistical significance was performed with a Chi Square Test of Independence. RESULTS: We identified 93 patients with EGJOO and a reliable past medical history documented in their chart. Upon analysis of our patient population, it was found that previously diagnosed depression (13.98%) and anxiety (12.9%) were common comorbidities. This was significantly higher than the prevalence of depression (6.7%, P = 0.0049) and anxiety (3.1%, P = 0.0001) in the United States. CONCLUSION: Depression and anxiety appear to show increased prevalence within patients diagnosed with EGJOO. EGJOO is generally known to be associated with structural obstructions, but importantly also seen in functional obstruction. This relation to mood disorders could suggest a psychosomatic component within certain subgroups. Whether EGJOO is an incidental finding or a true contributor to symptoms is not entirely clear. These correlations could trigger practitioners to think further about a diagnosis of EGJOO in their patients with anxiety or depression if they are displaying symptoms of dysphagia with associated manometric findings. Current treatment for EGJOO is not clearly established and treatment response is highly variable. Further studies looking into the relation of mood disorders with functional obstruction could lead to potential novel therapies.
