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

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.

Pneumatic dilatation in achalasia of the esophagus: a report from Argentina.

We review the treatment of esophageal achalasia by means of pneumatic dilatation (PD), analyzing its results and comparing them with those of the literature. We conclude that our personal experience is similar to that of the literature: PD and surgery produce similar results (67-95%), morbidity (2-9.5%), and mortality (0.
