Open<unk>  is similar in many respects to a normal cesarean section performed under general anesthesia, except that the fetus remains dependent on the placenta and is returned to the uterus. A hysterotomy is performed on the pregnant woman. Once the uterus is open and the fetus is exposed, the<unk>  begins.  Typically, this<unk>  consists of an interim procedure intended to allow the fetus to remain in utero until it has matured enough to survive delivery and neonatal surgical procedures.  Upon completion of the<unk> , the fetus is put back inside the uterus and the uterus and abdominal wall are closed up.
The mother remains in the hospital for 3-7 days for monitoring and is required to subsequently deliver the baby via a second cesarean section. Often babies who have been operated on in this manner are born pre-term.
Open<unk>  has proven to be reasonably safe for the mother.  For the fetus, safety and effectiveness are variable, and depend on the specific procedure, the reasons for the procedure, and the gestational age and condition of the fetus.
