Extraperitoneal cesarean section and general cesarean section have their own indications and contraindications, depending on the timing, condition and the level of the surgeon, and cannot be generalized.

It is a difficult operation and is rarely used clinically, and only people with associate chief physician qualification are qualified to perform it, It is not suitable for emergency cases.
