Opioid-Induced Esophageal Dysmotility (OIED) - A Case Report.

Recent studies have shown that chronic opioid use is associated with an increased risk of symptomatic esophageal motility disorders. Opioid-induced esophageal dysfunction (OIED) is most often identified in patients taking high doses of opioids. This condition is associated with poorer treatment outcomes than primary motility disorders and management of these cases is further complicated by the presence of chronic pain, opioid addiction, and physical and psychological comorbidity.
