An average of 1-2% of pregnant women in developed countries, are submitted to anesthesia for non-obstetrical surgery, with a range of 80,000 procedures per year . Intra-abdominal pathologies are the most commonly encountered surgical emergencies in pregnant women and diagnosis is hampered by factors such as nausea, vomiting, constipation, abdominal distension and pain related to normal pregnancy. Moreover, the physical examination of the abdomen in pregnancy has peculiar features particularly in the last weeks of pregnancy which can lead to late diagnosis. Appendicitis, cholecystitis, ovarian torsion, maternal malignancies and trauma are among the most common indications for surgical intervention. Appendicectomies are about 25% of these procedures (1:2,000 pregnancies). The position of the appendix during pregnancy alters, resulting in displacement of the McBurney's point which can difficult diagnosis, and classic signs of peritonitis may therefore be reduced or absent. Cholecystectomy is the second most frequently performed procedure (8-10:10,000), due to a state of gallbladder’s dyskinesia which increases the chance of stone formation. Anexial disease is also not uncommon and surgery may be required for diagnosis or treatment of ovarian pathology. In such situations, laparoscopic approach is increasingly being used. About 1 to 8% of anexial masses diagnosed during pregnancy are malignant and the delay in addressing them can worsen the outcome. Less common are cardiac and neurologic surgeries.
