Helicobacter Pylori Infection

To determine the diagnostic performance in the detection of Helicobacter pylori in biopsies taken only from the gastric antrum for the determination of the positive predictive value, the negative predictive value, and sensitivity and specificity.

Obese patients undergoing Local Anesthetics and Transnasal Endoscopy.

Obesity

Bariatric Surgery Candidate

Transnasal endoscopy without sedation with ultra-thin endoscopes in patients who are candidates for bariatric surgery

transnasal endoscopy

Will be carried out topical anesthesia of the pharynx with lidocaine spray (10%) 6 puffs and instillation of nasal vasoconstrictor 4 drops.

Local Anesthetics,Topical

Transnasal Endoscopy in Obese Patients Are Candidates for Bariatric Surgery

Transnasal Endoscopy in Obese Patients Are Candidates for Bariatric Surgery: Feasibility, Tolerance, Security and Cost-effectiveness.

The exam will be considered feasible if the appliance reaches the second duodenal portion and is performed retroflexão, allowing the visualization of all portions of the digestive system and the achievement of biopsies if necessary.
All patients will complete a questionnaire 15 to 30 minutes after the transnasal endoscopy and will be released next to the house.
All of this information and the results will be compared with the main data in the literature. Bivariate analyzes shall be calculated from the test "t" test for continuous variables and the chi-square test or Fisher exact test for categorical variables. Proportions will be reported by categorical data; and mean, median and standard deviation for continuous variables. P values less than 0.05 are considered statistically significant.

Participants can be identified by the number of medical records and phone contacts have been duly authorized by the institution responsible.
