Foreign body impaction in the esophagus: are there underlying motor disorders?

UNLABELLED: We observed in our practice several cases of impaction with meat boluses without bony edges, in patients with patent esophageal lumen. The aim of this study was to search for eventual underlying motor disorders which could be responsible for this impaction. We included 19 patients who attended the endoscopy service for meat bolus impaction without organic esophageal stenosis. This group was compared with 18 control volunteers. Both groups underwent UGI series, UGI endoscopy and low-compliance perfusion standard esophageal manometry. RESULTS: Compared with the control group, the impacted subjects presented marked reduction in amplitude and duration of esophageal contraction in the proximal esophagus. CONCLUSIONS: These motor disorders could be responsible for the foreign body impaction in the esophagus. However, we believe this patient group should be further studied by 24-hour esophageal manometry to reach a more accurate diagnosis by studying each patient's entire circadian cycle.
