Total Hysteroscopic Treatment of Cervical Pregnancy: The 2-step Technique

Abstract

To evaluate the efficacy of total surgical treatment of ectopic cervical pregnancy [1] with a minimally invasive approach performed by hysteroscopy [2]. Step-by-step video demonstration of the surgical technique using 5 mm hysteroscopy followed by 10 mm resectoscopy. A research and university hospital (IRCCS Burlo Garofolo, Trieste, Italy). A 41-year-old woman with an ultrasound diagnosis of ectopic cervical pregnancy at 6 + 6 weeks of gestation with a beta human chorionic gonadotropin serum level of 55.951 mUI/mL. We performed a 2-step technique using 5- and 10-mm hysteroscopy (Video 1). During the first step, a 5-mm Bettocchi hysteroscope (Karl Storz, Tuttlingen, Germany) with a 5F bipolar electrode Versapoint Twizzle (Gynecare, Menlo Park, CA) was used. In this phase, the gestational sac was identified in order to confirm the diagnosis and its site of implantation. Later, the gestational sac was opened, and the pregnancy was terminated by cord section under an embryoscopic view (Fig. 1). Finally, a partial vessel coagulation was performed. Afterward, the cervix was dilated, and a resectoscopy was performed. During the second step, a 10-mm Gynecare resectoscope with the bipolar Gynecare Versapoint was used and the gestational sac with the embryo was removed; subsequently, a complete chorial villi resection was achieved. At last, a coagulation of bleeding vessels on the implantation site in order to control the hemostasis was performed (Fig. 2). The study was approved by the institutional review board. The patient was discharged 24 hours after the procedure with an uneventful postoperative course, and the beta human chorionic gonadotropin serum level became negative in 20 days. After 40 days, the ultrasound cervical findings were regular, whereas office hysteroscopy showed the implantation site scar. After 5 months, the patient was pregnant with regular intrauterine implantation (Fig. 3). The total hysteroscopic approach with a 2-step technique offers an effective, safe, and minimally invasive surgical treatment to ectopic cervical pregnancy. Considering that our method, in contrast with the recent literature [3-5], is performed without any medical treatment, we reported for the first time an approach, that deserve more clinical data to confirm its effectiveness.
