Analysis is made of the results of ultrasound diagnosis of developmental abnormalities of the alimentary tract. It has been established that the information content of echography is dependent on the anatomic intensity of an abnormality and the period of pregnancy at which the examination was done. It has been shown that the method is not of high diagnostic significance in revealing developmental abnormalities of the upper lip and hard palate, atresia of the esophagus, large intestine and rectum. At the same time atresia of the duodenum, small intestine, omphalocele, gastroschisis, diaphragmatic and inguino-scrotal hernia are detectable in practically 100% of cases. The authors provide echograms of the majority of abnormalities, indicate the minimal times of detection, analyze the causes of diagnostic errors.
