Laparoscopic treatment of heterotopic pregnancy

The increasing frequency of pelvic inflammatory disease and use of ovulation-induction agents has resulted in a corresponding increase in the frequency of heterotopic pregnancy. In most reported cases the diagnosis was made retrospectively at the time of laparotomy. With improvements in ultrasonography and operative laparoscopy, the diagnosis can be made preoperatively and the disease treated surgically with low morbidity. In a woman who had received clomiphene citrate for ovulation induction, the diagnosis of heterotopic pregnancy was suspected preoperatively based on transvaginal ultrasonography. The patient was treated laparoscopically by partial salpingectomy, and subsequently delivered a normal infant.
