text: [Polyps esophageal cardio-conversion in children: causes, clinical picture, management and prognosis of tactics].
  105 children with polyps of esophago-gastric junction region, detected by gastroscopy, were under follow up during 1-9 years. 55 children with polyp size less than 5 mm were followed up without endoscopic polypectomy (EP) and 50 children with polyp size more than 5 mm and another indications underwent EP. Polyps were more frequently encountered in males aged 7-15 years without specific clinical symptoms; histologically, there were hyperplastic polyps. The majority of children (94.5%) treated conservatively were found to have absence of growth or polyp regression. Risk factors of reappearing of polyps after EP were progress of esophagitis and abnormal gastroesophageal flap valve. According to results of 24-hour pH monitoring of esophagus, alkaline gastroesophageal reflux was diagnosed only in patients with polyps in comparison with children without polyps with chronic diseases of upper floor of digestive tract (p = 0.04).
