Child, 5 days from the first pregnancy, birth weight 3200g. The pregnancy was proceeding normally. From the moment of birth, the child had no stool, frequent vomiting, anxiety, bloating. On examination, the anus is present, but probing cannot be performed. What pathology should you think about in this case? What is the reason for the occurrence of this malformation?

Atresia of the anus arose as a result of a violation of cell death: the cells that fill the lumen of the anus during embryogenesis were preserved.
