Abstract

Abstract: Background: Opioid receptors are present in the esophagus, and chronic opioid therapy may be associated with esophageal dysfunction. Given the current opioid epidemic in the United States, the potential contribution of opioids to esophageal dysmotility is important from both public health and patient care perspectives. Therefore our aim is to investigate the potential contribution of opioids to dysphagia and the prevalence of major motor disorders in patients undergoing manometric evaluation. Methods: The anonymized electronic medical records of patients linked to their de‐identified high‐resolution manometry (HRM) studies were reviewed. The patients were grouped based on their opioid exposure history at the time of HRM: opioid‐naïve and chronic daily users. The oral morphine milligram equivalent daily dose (MMED) of opioids was computed. Key Results: 10% of patients referred for esophageal HRM were taking opioid analgesics on a chronic daily basis, and they had a significantly higher prevalence of dysphagia than their opioid‐naïve counterparts. The chronic daily opioid users displayed a significantly higher prevalence of achalasia type 3 (ACH3) and esophagogastric junction outflow obstruction (EGJOO) motility phenotypes. The MMED of opioids was a significant predictor of esophageal pressure metrics and motility diagnoses ( P < 0.0001). Conclusions: Chronic daily opioid intake is associated with impaired deglutitive LES relaxation and disorganized peristaltic sequence. While a minority of patients on chronic daily opioid therapy present with major esophageal motor disorders, they comprise nearly half of ACH3 and a third of EGJOO motility phenotypes. Abstract : Nearly 10% of patients referred for esophageal motility testing are on chronic daily opioids. Higher daily doses of opioids are associated with impaired deglutitive LES relaxation and disorganized peristaltic sequence.
