ANIDO ESCOBAR, Vivianne et al. Motility factors at Barrett's Esophagus, according different endoscopic presentation. Rev haban cienc méd [online]. 2013, vol.12, n.3, pp.343-353. ISSN 1729-519X.

Background: Barrett's esophagus is considered one of the most severe complications of gastroesophageal reflux disease, because its association with esophageal adenocarcinoma. Although motility studies show significant abnormalities at the antireflux barrier, not all patients show the same affectations. Aims: by conventional esophageal manometry to define the characteristics of motility factors at antireflux barrier and esophageal motor disorders, in patients with Barrett, according to different endoscopic presentations. Material and Methods: esophageal manometry was performed to a group of patients with Barrett, histologically confirmed. Characteristics of the antireflux barrier and esophageal body peristalsis were recorded. There were applied statistical techniques for the association between variables (multiple correlation and regression). Results: predominance of patients with short segment, 61.3% male and a mean age of 47.7 years. Patients with long segment were lower resting pressure of the lower esophageal sphincter and larger hiatal hernias, while in patients with short segment, instability prevailed. Severe motor disorders predominated, with over 30% of failures of responses, but they were more important in patients with short-segment Barrett. Conclusions: Tthere were differences in motility patterns between the group of patients with short-segment and long segment Barrett Esophagus.
