Obesity is correlated with several comorbidities, including gastroesophageal reflux disease. Its main complications are detectable by endoscopy: erosive esophagitis and Barrett's esophagus.
: To correlate erosive esophagitis and hiatal hernia with the degree of body mass index (BMI).
: Was performed a retrospective analysis of 717 preoperative endoscopic reports of bariatric patients. Fifty-six (8%) presented hiatal hernia, being 44 small, nine medium and five large. Esophagitis was classified by Los Angeles classification.
: There was no correlation between the presence and dimension of hiatal hernia with BMI. One hundred thirty-four (18.7%) patients presented erosive esophagitis. Among them, 104 (14.5%) had esophagitis grade A; 25 (3.5%) grade B; and five (0.7%) grade C. When considering only the patients with erosive esophagitis, 77.6% had esophagitis grade A, 18.7% grade B and 3.7% grade C. Were identified only two patients with Barrett's esophagus (0,28%).
: There was a positive correlation between the degree of esophagitis with increasing BMI.
