[Fiber-optic endoscopy of the lower gastrointestinal tract in children].

Between 1978 and 1985 565 lower gastrointestinal endoscopies were performed in children. In 221 cases the cause of rectal bleeding was explored, in 227 the suspicion of colitis and in 25 of polyposis was verified. To evaluate the results of treatment (polypectomy, surgical procedures and medical therapy in inflammatory bowel disease) 121 examinations were done.

[Barrett esophagus].

An analysis of the clinical picture of Barrett's esophagus in 18 children is presented. This group of patients have been distinguished out of 114 children with chronic gastroesophageal reflux on the base of anatomopathological examinations. Clinical course and efficiency of the diagnostic examinations depend on the degree of esophagitis.
