Objective: to evaluate esophageal motor function in children with a history of endoscopic esophageal dilations due to caustic stenosis. Method: a prospective cross-sectional study that included: upper GI endoscopy with biopsy taken at the distal esophagus, esophageal manometry and 24 hours pH metry. Results: Six patients presented/displayed caustic esophagitis IIB, four caustic esophagitis IIIA and one caustic esophagitis IIIB at the moment of the accident. Six (54.5%) patients showed inefective motility and 4 (36.3%) aperistalsis of the esophageal body. When correlating the esophageal injury at the time of ingesting the caustic with the motility disorder of the esophagus shown during manometry there was no statistical association (p=0, 2). There is also no correlation between the alteration of the esophageal motility and the time of evolution from the accident to the moment of this study (p=0,9). A statistical significant association was demonstrated between the esophageal motor disorder and the number of endoscopic dilations, as well as with the time needed to solve the stenosis. Conclusions: Patients who ingest caustics and suffer moderate to severe esophageal injuries have a high probability of presenting/displaying important motor disorders. We demonstrate the association between the number of dilations necessary to solve the stenosis and the aperistalsis of the esophagus.
