Laparoscopic surgery during pregnancy.

BACKGROUND

Animal studies have demonstrated fetal acidosis during carbon dioxide pneumoperitoneum. This finding suggests a potential adverse effect of CO2 pneumoperitoneum on fetal outcome in humans.

PATIENTS AND

METHODS

We reviewed our recent experience with laparoscopic surgery performed under general anesthesia and with the use of CO2 pneumoperitoneum, in pregnant women with appendicitis or cholecystitis. We compared these women's charts and pregnancy outcomes with those of pregnant women who underwent formal laparotomy during the same period of time.

RESULTS

Seven pregnant patients underwent laparoscopic surgery, and there were 4 fetal deaths among them (3 during the first postoperative week, and another 4 weeks postoperatively). Five pregnant patients underwent formal laparotomy, of whom 4 subsequently progressed to term and 1 was lost to follow-up.

CONCLUSIONS

Our recent experiences together with the available animal data suggest that caution should be used when considering nonobstetrical laparoscopic surgery in pregnant women. This experience suggests that additional clinical and laboratory investigations may be indicated to evaluate fetal risk associated with such surgery.
