Aim: Microscopic bowel inflammation is present in up to 60% of all patients with spondyloarthritis (SpA) and appears to be associated with more severe joint disease and a higher risk of developing inflammatory bowel disease (IBD). This study aimed to determine the utility of fecal calprotectin (fCAL) in evaluating endoscopic and histological bowel inflammation in SpA patients.

Methods: Ileocolonoscopies with biopsies and fCAL measurements were performed in 65 patients with SpA.

Background: The effects of vertical banded gastroplasty/Roux-en-Y gastric bypass (Capella) on the esophageal mucosa of patients with histological esophagitis are poorly understood. To evaluate long-term effects, we investigated the persistence, aggravation or disappearance of histological esophagitis in patients with morbid obesity and reflux esophagitis (diagnosed by endoscopic biopsy) after Roux-en-Y gastric bypass.

Methods: Twenty-one patients with morbid obesity and esophagitis (histological diagnosis) were submitted to gastric bypass (Fobi-Capella technique) and underwent upper endoscopy and esophageal biopsy during the late postoperative period.
