Background: Gastric bypass is a recognized treatment to improve Gastroesophageal reflux disease (GERD) in obesity. The aim of this study was to assess the performance of the Montreal Consensus in the diagnosis of postoperative GERD among patients who had Gastric bypass for morbid obesity.
Methods: 53 consecutive morbidly obese patients submitted to Gastric Bypass [15 men (28%), 41 years old (range, 21-62)], were evaluated after 39 ± 7 months with GERD symptoms assessment, upper gastrointestinal endoscopy, and ambulatory esophageal pH monitoring. The performance of the Montreal Consensus was determined by matching the standardized assessment which includes both endoscopy and pH monitoring for non troublesome gastroesophageal reflux symptoms with the Montreal Consensus.
Results: The mean BMI in the postoperative period was 30 ± 5.2 kg/m2. Three patients reported heartburn while other three reported regurgitation. Endoscopic examination revealed esophagitis in 10 patients and pH-metry showed pathologic reflux in 13 patients (DeMeester score). Compared with endoscopy, the Montreal Consensus showed sensitivity of 86% and specificity of 100% (p <0.05). In the comparison with the diagnosis by ph-metry the sensitivity was 80% and the specificity was 100% (p <0.05).
Conclusion: In the postoperative period of Gastric Bypass the evaluation of GERD through the Montreal Consensus presents high specificity, but with a more limited sensitivity.
