Laparoscopic Management of a Heterotopic Pregnancy in the Tubal Stump

Abstract

To demonstrate how a heterotopic tubal stump pregnancy can be safely managed with laparoscopy, preserving the intrauterine pregnancy. Stepwise demonstration of the technique by means of a video tutorial. The management of pregnancies in the tubal stump after salpingectomy involves either a surgical intervention or systemic therapy. In case of a simultaneous intrauterine pregnancy, although the prognosis for the fetus remains good with live births in approximately 70% of the cases, the surgical management of the tubal stump pregnancy is challenging owing to the risk of bleeding from the uterine horn [1-5]. We present an effective and reproducible laparoscopic technique on the basis of a 31-year-old patient with 2 prior right fallopian tube pregnancies, which were later treated with salpingectomy. The patient is now presenting in the sixth week of gestation after transfer from 2 oocytes with a pregnancy in the tubal stump and a concomitant vital intrauterine pregnancy. The key steps of laparoscopic surgery include (1) continuous absorbable monofilament suture on the uterine horn around the tubal stump to achieve hemostasis and exposure of the proximal part of the tube, (2) removal of ectopic pregnancy, and (3) closure of the excision site with continuous absorbable polyfilament suture. The instillation of vasoconstrictive substances and the use of electrical coagulation should be avoided. The demonstrated laparoscopic technique is a feasible method of removal of a tubal stump pregnancy without interfering with the vital intrauterine pregnancy. The blood loss can be minimized, and laparotomy can be avoided.
