[Perinatal risk in emergent surgery].

During pregnancy, appendicitis, cholecystitis, choledocholithiasis, intestinal obstruction, and ulcers can lead to complaints and complications which occasion emergent surgery. The disease as such, its complications, the surgical intervention, and the anesthesia represent a risk for both mother and child. Risks arise particularly often due to the delay of diagnosis and therapy. Risk to the child depends on gestational week, fetal lung maturity, and oxygen supply.
