Laparoscopic surgery for heterotopic pregnancies: a case report and a brief review

A heterotopic pregnancy is in effect a multiple pregnancy with one or more intrauterine pregnancies coexisting with an ectopic pregnancy and is rarely spontaneous. With the increasing popularity of ovulation induction performed during assisted reproductive techniques, it will not be surprising to observe that this phenomenon has increased significantly. However, diagnosis is often delayed because of its rarity and difficulty. We report a case of a woman with a viable intrauterine pregnancy who had a complication of ovarian hyper-stimulation syndrome secondary to ovulation induction following in vitro fertilization and embryo transfer, but who, during hospitalization, presented with clinically progressive abdominal pain. An unruptured ectopic pregnancy of the right fallopian tube was diagnosed accidentally by laparoscopy and laparoscopic salpingectomy was immediately performed. Post-operative follow-up revealed that the intrauterine pregnancy continued normally. She delivered a normal female baby at 38 weeks of gestation. The promising neonatal outcome might suggest that laparoscopy might be safely performed to aid differential diagnosis in an uncertain condition during pregnancy: therefore, laparoscopic surgery might be an appropriate method to manage some carefully selected patients with HP. A brief review of the published literature on the role of laparoscopy in the diagnosis and management of heterotopic pregnancy is given.
