ILEAL ATRESIA PRODUCED BY INTUSSUSCEPTION IN UTERO
We experienced 3 cases of ileal atresia, which was considered to be produced by intussusception in the late stage of pregnancy. We attributed ileal atresia to intussusception in utero because of the following findings;(1) the shortage of the whole length of the small intestine, (2) the normal meconium in the large intestine, (3) defect of the mesentery,(4) no associated malformation, and (5) histologically unique polypoid prominence in the distal blind end. Histological studies of our 3 cases lead us to the hypothesis about the pathologic process of spontaneous recovery of intussusception in utero. According to this hypothesis, we presumed that the probability of the natural cure is greater than that of the atresia.
