The DJBL improves glycemic status in obese subjects with diabetes and therefore represents a nonsurgical, reversible alternative to bariatric surgery.

The DJBL, when used for a period of 6 months, is effective in the control of diabetes, weight loss, improvement of insulin resistance, and decrease of cardiovascular risk among morbidly obese patients with type 2 diabetes mellitus.

BackgroundIn patients with chronic diarrhea, colonoscopy may identify inflammatory causes or some occult disease, and also can show a normal mucosa. Serial biopsies of intestinal mucosa can be useful for a differential diagnosis, and to modify the treatment.AimTo evaluate whether the biopsies performed in patients with chronic diarrhea and a normal colonoscopy contribute to the differential diagnosis and alter the therapeutic approach.MethodsA descriptive, retrospective and cross-sectional study using a computerized database was done. Patients with chronic diarrhea and a normal colonoscopy underwent serial biopsies of the terminal ileum, ascending colon and rectum.ResultsFrom 398 records, 214 were excluded. Of the 184 patients enrolled, 91 showed histological changes: 40% nonspecific inflammation; 5.18% lymphocytic inflammation, 10.37% eosinophilic inflammation; 39.26% lymphoid hyperplasia; 2.22% collagenous colitis; 2.22% melanosis; and 0.74% pseudomelanose. The sites with the largest number of changes were the terminal ileum and right colon.ConclusionsSerial biopsies in patients with chronic diarrhea and normal colonoscopy identified changes in almost 50% of cases and 22% of these cases may had modified the treatment after identification of collagenous, lymphocytic and eosinophilic colitis.

DJBL delays gastric emptying but is reversible after withdrawal. The changes in gastric emptying have no relationship to weight loss and T2DM control.

BackgroundGastroesophageal reflux disease is an increasingly common condition worldwide causing a considerable economic impact. More than half the patients with clinical symptoms of reflux disease display no mucosal erosions on esophagogastroduodenoscopy, making it impossible to confirm the diagnosis without further investigations.AimTo evaluate the correlation between minimal endoscopic changes on white-light esophagogastroduodenoscopy (carditis, mucosal thickening and invisibility of vessels) and histologic changes observed in distal esophageal biopsies in a sample of patients with symptoms suggestive of reflux disease, and to verify the specificity of these symptoms for non-erosive reflux disease.MethodsRetrospective, cross-sectional study based on information retrieved from a digital database at a Brazilian hospital for the period March-October, 2012. The sample consisted of previously untreated, non-smoking subjects aged >18 years with symptoms suggestive of reflux disease but no esophageal erosions, submitted to esophagogastroduodenoscopy and distal esophageal biopsy.ResultsThe final sample included 23 subjects. The most frequently observed change was invisibility of vessels (n=21; 91.3%), followed by mucosal thickening (n=15; 65.2%) and carditis (n=5; 21.7%). The correlation coefficient between each variable and the anatomopathological diagnosis was 0.386 for body mass index, 0.479 for mucosal thickening, -0.116 for invisibility of vessels, 0.306 for carditis and 0.462 for hiatal hernia.ConclusionAll patients displayed minimal endoscopic changes on esophagogastroduodenoscopy, but only mucosal thickening revealed a moderately significant correlation with severity of esophagitis, although increased body mass index values and the presence of hiatal hernia were also associated.
