[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. They are slightly characteristic in children with minimal lesions. Long-term follow up - necessary due to the risk of cancer - have shown that there is possibility of recovery in cases of minimal advancement and short duration of the disease.

[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. With increasing experience the complete colonoscopy was performed more often. In 1985 coecum and ileum terminale was reached in almost all children in whom it was needed (75% of all examinations). The inflammatory changes were revealed on 230 occasions. In 78 cases colon polyps and in 27 vascular changes were found. The most common cause rectal bleeding were colon polyps (66 cases) and inflammatory changes (554 cases). Less common were vascular changes (10 cases). 32% false negative and 16% false positive results of colonoscopy in diagnosis colitis were obtained when the results of visual findings were compared with histopathological findings. Colonoscopy performed by an experienced colonoscopist rather avoiding general anesthesia is a safe and useful procedure in diagnosing lower gastrointestinal tract diseases in children. The evaluation of colitis should be based on visual findings with biopsy confirmation.

Short- and long-term results of colonoscopic polypectomy in children.

Eighty-four colorectal polyps of up to 3.3 cm in diameter were removed with the diathermy snare during 48 colonoscopies on 42 children, aged 2 to 18 years (mean, 7.4 years). Most polyps were juvenile and the majority were located in the sigmoid colon (55%) or rectum (37%). No complications related to medication, colonoscopy, or snare polypectomy were observed. The two presenting symptoms, rectal bleeding and anemia, disappeared soon after polypectomy in all but one patient with adenomatous polyposis coli, subsequently operated upon. Follow-up examinations, including total colonoscopy, performed 4 months to 7 years (mean, 25 months) later did not reveal abnormalities in any of the 37 children whose previously removed polyps were juvenile. The authors conclude that endoscopic snare polypectomy is an effective and safe treatment for colorectal polyps in the pediatric age group.
