RARE COLORECTAL MALFORMATIONS IN NEWBORNS. LITERATURE REVIEW AND OWN OBSERVATIONS

The article presents literature data andown observations of some rare congenital malformationsof the colorectal area in newborns that require surgicaltreatment. These are defects such as congenital pouch colonand congenital segmental dilatation of the colon. Thereare isolated cases of birth of children with these defectsin European countries and North America. They are morecommon in Asian countries, especially in India. Diagnosisand surgical correction of such congenital malformationscause difficulties associated with insufficient awarenessof pediatric surgeons, neonatologists, pediatricians aboutthis pathology. Data is presented on clinical manifestations,antenatal and postnatal diagnosis and treatment tactics, aswell as the histopathological structure of the affected colonin these defects.The analysis of literature data and the presented clinicalobservations of congenital pouch colon and congenitalsegmental dilatation of the colon in newborns indicate thepossibility of their antenatal and preoperative diagnosis.It is concluded that children with anorectal malformationsand Hirschsprung's disease require a thorough differentialdiagnosis with congenital pouch colon and segmentaldilatation of the colon, as the tactics of their surgicalcorrection significantly differ from the treatment tacticsof common anorectal malformations and Hirschsprung'sdisease surgical management.
