Summary
Individuals with a hiatal hernia (HH) were 2.57 times more likely to have cricopharyngeus muscle (CPM) dysfunction (CPMD). This study suggests a link between GERD and CPMD, warranting further investigation into the etiology of CPMD.
Area of Science:
- Gastroenterology
- Otolaryngology
- Radiology
Background:
- Cricopharyngeus muscle (CPM) dysfunction (CPMD) etiology is unclear, with hypotheses suggesting it may compensate for gastroesophageal reflux disease (GERD).
- Investigating the association between CPMD and hiatal hernia (HH) could elucidate CPMD's origins.
Purpose of the Study:
- To evaluate the association between CPMD and the presence of HH.
- To explore potential etiological factors for CPMD.
Main Methods:
- Retrospective review of video fluoroscopic esophagrams from 01/01/14 to 10/30/16.
- Comparison of CPMD prevalence between 50 subjects with HH and 50 age- and gender-matched controls without HH.
Main Results:
- The HH group showed a higher prevalence of CPMD (78%) compared to the non-HH group (58%).
- Individuals with HH were 2.57 times more likely to exhibit CPMD (95% CI 1.07–6.15).
Conclusions:
- Data indicate a potential association between GERD (as indicated by HH) and CPMD.
- Further research is necessary to establish a causal relationship between GERD and CPMD.
