Laparoscopically assisted hysteroscopic removal of an interstitial pregnancy

Abstract

To illustrate a combined technique of hysteroscopy and laparoscopy for the management of interstitial ectopic pregnancies. A description of a patient case and demonstration of a surgical technique. Tertiary referral center. A 33-year-old woman, gravida 2, para 0-0-1-0 status post invitro fertilization cycle with single embryo transfer, was diagnosed with an unruptured right interstitial pregnancy at 5 weeks of gestation. She has a history of a pregnancy of unknown location with her first invitro fertilization transfer and received methotrexate. The beta-human chorionic gonadotropin level was 2,726 mIU/mL. She was counseled on treatment options and declined treatment with methotrexate because of the negative side effects she experienced previously. She opted for surgical management and desired to keep her fallopian tubes if possible because she wished to try for spontaneous conception. The patient underwent multipuncture video laparoscopy, and a bulge was seen at the right cornua. Video hysteroscopy initially revealed an empty uterine cavity. Using atraumatic graspers, the interstitial pregnancy was gently pushed further into the uterine cavity using a milking technique. The pregnancy was then able to be visualized hysteroscopically. Products of conception were gently dislodged and removed with graspers, followed by a suction curettage. This technique resulted in minimal blood loss, preservation of reproductive organs, and expedient return to conception planning. The postoperative course was uncomplicated, and the patient was discharged the same day as surgery. After the procedure, weekly beta-human chorionic gonadotropin was drawn until the level reached <1 mIU/mL, which occurred after 4 weeks. Hysterosalpingography was performed 2 months after the procedure and demonstrated bilateral tubal patency. In select patients, an early interstitial pregnancy can be safely removed using the described technique. Although hysteroscopic removal of interstitial pregnancies is not a new concept, the addition of simultaneous video laparoscopy provides the benefit of allowing for fertility-sparing removal of the pregnancy, even if it is not initially visualized hysteroscopically. The use of this technique may result in minimal blood loss and preservation of the fallopian tubes. Furthermore, with the myometrium integrity maintained, the patient may resume sooner attempts at conception.
