8407 Interstitial Ectopic Pregnancy: A Case Series with Practical Tips for Surgical Management

Abstract

<h3>Study Objective</h3> To review current treatment options for interstitial ectopic pregnancy (IP), with a focus on surgical treatments. To review outcomes of three surgically managed cases of IP. To demonstrate practical tips for success in laparoscopic management of IP. <h3>Design</h3> A case series presenting three cases of surgically managed IP with guided explanation of surgical intervention using video. <h3>Setting</h3> Academic affiliated community hospital. <h3>Patients or Participants</h3> The 3 cases of IP evaluated and treated over the past year were included in the study. <h3>Interventions</h3> Two patients underwent laparoscopic cornual resection of IP and one patient underwent emergent abdominal repair of ruptured IP. <h3>Measurements and Main Results</h3> Estimated blood loss (EBL) for laparoscopic management of 6-week IP with preoperative uterine artery embolization (UAE) was 20ml; length of post operative length of stay (LOS) was 1 day. EBL for 13-week IP without embolization was 50 ml, post op LOS was 0 days. EBL for ruptured IP repaired via open approach was 1000ml including hemoperitoneum, post operative LOS was 2 days. Beta hCG was trended once per week post operatively for all patients. Both patients undergoing laparoscopic resection had negative HCG by week 4. The patient with ruptured IP had negative hCG by week 8; however, she did not complete testing between week 5-7; at 4 weeks her hCG was 17. <h3>Conclusion</h3> IP is sometimes a difficult diagnosis to make; a high index of suspicion is necessary. Laparoscopic surgery for IP is achievable using similar techniques as laparoscopic myomectomy for limiting perioperative blood loss and repair of the myometrial defect; Ultrasonic scalpel, vasopressin, delayed absorbable barbed suture. IP can often be treated laparoscopically, however laparotomy may be necessary in unstable patients with advanced gestation. Further investigation is necessary to determine the best practice for surgical management of IP.
