A fetal sacrococcygeal tumor obstructing labor after attempted home confinement.

Obstructed labor due to a large sacrococcygeal tumor is reported. A technique of transabdominal intrauterine reduction in the size of the tumor to allow delivery of the infant in satisfactory condition is described. The method and the successful outcome have not previously been reported. It is recommended as a combined obstetric and pediatric surgical solution to similar complications. The complication should be circumvented by ultrasonographic screening of high-risk or suspect cases and of women entering a high-risk environment for delivery.
