Laparoscopic Management of Abdominal Pregnancy.

OBJECTIVE: To illustrate the laparoscopic surgical management of a particular localization of extrauterine pregnancy misdiagnosed until 12 weeks gestational age, complicated by hemoperitoneum and abortion.

DESIGN: Canadian Task Force III on the Periodic Health Examination's Levels of Evidence.

SETTING: The prevalence of ectopic pregnancy among women presenting to an emergency department with first trimester bleeding, pain, or both ranges from 1% to 16% [1]. The most common localization of ectopic pregnancy is the fallopian tubes, whereas abdominal pregnancy accounts for at least 1% of extrauterine pregnancies. The reported incidence of abdominal pregnancy ranges from 1:10 000 to 1:30 000 pregnancies [2]. Abdominal pregnancy can be localized in the pelvic cul-de-sac, broad ligament, bowel, or pelvic sidewall. This rare type of ectopic pregnancy is often misdiagnosed until later in pregnancy, evolving in hemoperitoneum, abortion, embolism, or rarely, in diagnosed cases, live birth by cesarean section. In the literature, it is recommended that the placenta be left in situ in cases of abdominal pregnancy to avoid hemorrhage and organ injury, even though this approach may be associated with a higher rate of postoperative complications, such as infection, secondary bleeding, and cancer transformation [3]. We present a case of abdominal pregnancy in which the gestational sac was implanted in the broad ligament and resulted in hemoperitoneum at 12 weeks gestational age.

INTERVENTION: In August 2010, a 35-year-old woman, gravida 3 para 1, presented at the Di Meglio ultrasound diagnostic center in Naples for a noninvasive prenatal ultrasound (bi-test) to confirm gestational age in what to that point had been considered a normal pregnancy at 12 weeks gestation. Ultrasound revealed an ectopic abdominal pregnancy with a live fetus located in the left parauterine side. A suspicious fluid level in the pouch Douglas was also detected, and so the woman was advised to go to an obstetric hospital for a medical evaluation of the clinical situation (starting hemoperitoneum). Later that same day, the woman presented at the Villa dei Platani Hospital in Avellino, where ultrasound confirmed increased fluid in the pouch of Douglas, along with initial signs of hemoperitoneum and loss of the fetal heartbeat. The woman was immediately transferred to the Malzoni Center for Advanced Endoscopic Gynecological Surgery in Avellino, where she underwent operative laparoscopy for removal of the abdominal pregnancy (surgeon, M.M.). Informed consent for the laparoscopic surgery was provided by the patient in accordance with local regulations. The patient also provided informed consent for the use of images and a video of the procedure. Institutional Review Board approval was not required. The procedure involved laparoscopic hemoperitoneum drainage (at least 500 mL of blood), left adnexectomy after transperitoneal identification of the left uretheral pathway, and complete removal of left broad ligament pregnancy abortion with consensual removal of the ectopic placenta.

CONCLUSION: The laparoscopic management of abdominal pregnancy and hemoperitoneum resulting from rupture of the gestational chamber and abortion was optimal. With this minimally invasive technique, it was possible to drain the hemoperitoneum completely and then proceed to total removal of the gestational chamber and the fetus. Thanks to the magnification of the image by laparoscopy, it was also possible to completely remove the placenta and the cotyledons from the peritoneal surface, thereby avoiding possible postoperative bleeding, infection, and sepsis resulting from retention of incomplete removal of the placenta. On the first postoperative day, the patient was in excellent clinical condition, with a marked reduction in circulating β-human chorionic gonadotropin. She was discharged on the second postoperative day and currently is in good health.
