Abstract
INTRODUCTION
We aimed to conduct a systematic review and meta-analysis to assess the impact of chronic opioid exposure on esophageal motility in patients undergoing manometric evaluation.
METHODS
Multiple databases were searched through October 2022 for original studies comparing the manometric results of patients who have used chronic opioids (for >90 days) with those who do not. The primary outcomes were esophageal dysmotility disorders. Three high-resolution manometry parameters were conducted as secondary outcomes. A random-effects model was applied to calculate the odds ratio (OR) and means difference (MD) along with a 95% confidence interval (CI).
RESULTS
Nine studies were included in this meta-analysis. Opioid use was associated with higher esophageal dysmotility disorders, including distal esophageal spasm (pooled OR 4.84, 95% CI 1.60-14.63, P = 0.005, I 2 = 96%), esophagogastric junction outflow obstruction (pooled OR 5.13, 95% CI 2.11-12.43, P = 0.0003, I 2 = 93%), and type III achalasia (pooled OR 4.15, 95% CI 2.15-8.03, P < 0.0001, I 2 = 64%). No significant differences were observed for hypercontractile esophagus, type I achalasia, or type II achalasia. The basal lower esophageal sphincter pressure (MD 3.02, 95% CI 1.55-4.50, P < 0.0001, I 2 = 90%), integrated relaxation pressure (MD 2.51, 95% CI 1.56-3.46, P < 0.00001, I 2 = 99%), and distal contractile integral (MD 640.29, 95% CI 469.56-811.03, P < 0.00001, I 2 = 91%) significantly differed between the opioid use and nonopioid use group. However, opioid use was associated with a lower risk of ineffective esophageal motility (pooled OR 0.68, 95% CI 0.49-0.95, P = 0.02, I 2 = 53%).
DISCUSSION
Chronic opioid exposure is associated with an increased frequency esophageal dysmotility disorders. Our results revealed that opioid use is significantly associated with type III achalasia but not with type I and II achalasia. Therefore, opioid treatment should be taken into account as a potential underlying risk factor when diagnosing these major esophageal motor abnormalities.
