Resumo: | CONTEXT: Barrett's esophagus (BE) is characterized by intestinal metaplasia in the distal esophagus and is classified as short-segment (<3 cm - SSBE) or long-segment (>3 cm - LSSBE). It is suggested that LSSBE is associated with more severe esophageal motor abnormalities and increased acid exposure time than SSBE. OBJECTIVE: To evaluate the prevalence of esophageal manometriy abnormalities and acid exposure times in patients with SSBE and LSSBE. METHODS: Barrett's esophagus patients identified by upper endoscopy and confirmed by histopathology were, retrospectively, reviewed and divided into two groups: SSBE and LSBE. Demographic data, symptom duration, prevalence of hiatal hernia, lower esophagus sphincter basal pressure, prevalence of esophageal body abnormalities and acid exposure times were evaluated. RESULTS: Forty-six patients with SSBE (24 males - 52.2%, mean age of 55.2 years) and 28 patients with LSBE (18 males - 64.3%, mean age of 50.5 years). Mean symptom duration was 9.9 years for SSBE and 12.9 years for LSSBE. Hiatal hernia was present in 84.2% of SSBE, 96.3% of LSBE; average lower esophagus sphincter pressure in SSBE 9.15 mm Hg, in LSBE 6.99 mm Hg; lower esophagus sphincter hypotension in SSBE was 65.9%, in LSSBE 82.1%; aperistalsis in SSBE 6.5%, LSSBE 3.6%; mild/moderate ineffective esophageal motility in SSBE 34.8%, LSBE 46.4%; severe moderate ineffective esophageal motility in SSBE 10.9%, LSBE 7,1%; nutcracker esophagus/segmental nutcracker esophagus in SSBE 8.6%, LSBE 0%; normal body in SSBE 39.1%, in LSBE 42.9%, no statistical difference for any of these values (P<0.05). Average % total time pH<4 in SSBE 9.12, LSBE 17.27 (P<0.000); % time pH<4 upright in SSBE 11.91; LSBE 24.29 (P=0.003); % time pH<4 supine in SSBE 10.86, LSBE 33.26 (P = 0.000). CONCLUSION: There was no difference between the prevalence of motor disorders in patients with SSBE and LSSBE. Acid reflux in upright and supine positions was more intense in LSBE. |
