Laparoscopic Excision of Noncommunicating Uterine Horn Pregnancy
The patient was a 29-year-old G1P0 female presenting with a live 11-week extrauterine pregnancy. Radiologic work-up with both pelvic ultrasound and MRI could not fully ascertain diagnosis.
Differential diagnosis included tubal ectopic, horn pregnancy of a bicornuate uterus, interstitial pregnancy, and broad ligament pregnancy.
Given this was a wanted pregnancy, intra-sac potassium chloride was not administered pre-operatively and the patient was consented for a diagnostic laparoscopy and possible removal of ectopic pregnancy. Laparoscopy revealed a large left rudimentary horn pregnancy.
Our video demonstrates a stepwise approach for the excision of such pregnancies including isolation of the ureter retroperitoneally, bladder dissection, use of peritoneal landmarks to ensure safe transection of the fibrous band, and use of hemostatic techniques such as vasopressin and advanced bipolar devices.
In addition, we demonstrate a simple technique for oophoropexy where we stabilize a hypermobile ovary to the round ligament pedicle using a laparoscopic ligature device.
