[Upper gastrointestinal endoscopy in children: indications and results]

OBJECTIVE: To present and discuss the indications, the endoscopic and histologic findings and the complications of upper digestive endoscopies carried out in children and adolescents.METHODS: We have done 228 endoscopies in pediatric patients with ages between 3 months to 19 years (x=5.7 y) during a period of 8 months. General anesthesia was used in 80% of patients (182). Biopsies were done in 210 patients and the Helicobacter pylori was searched for in 130 patients by antral biopsies with Hematoxylin-Eosin coloration.RESULTS: The endoscopy indication was diagnostic in all patients, and in 18 cases there was some therapeutic procedure. Fifty-eight percent of examinations presented endoscopic alteration and 84% had abnormal histologic findings. The most frequent endoscopic findings were esophagitis in 50 patients, gastritis in 44 and duodenitis in 29. Ten peptic ulcers were diagnosed. Between the histologic findings the most frequent ones were gastritis in 87 patients, esophagitis in 50 and atrophy of duodenal mucosa in 9. The H. pylori was positive in 25 (19.2%) patients.CONCLUSION: The upper digestive endoscopy has become an essential procedure to the pediatric gastroenterology practice, amplifying the available diagnostic means and enabling therapeutic endoscopy in the presence of upper digestive lesions. In the present report, 58% of the studied population presented some endoscopic lesion.
