Interstitial Ectopic Pregnancy—A Step-by-Step of Laparoscopic Cornuostomy Technique

Objective: To demonstrate the laparoscopic conservative technique (cornuostomy) for the interstitial pregnancy. Material and Methods: Demonstration of the laparoscopic cornuostomy technique for the interstitial pregnancy with narrated video. The optimal treatment approach for interstitial pregnancy remains uncertain and surgical treatment may include cornuostomy, cornual resection, or hysterectomy. Results: The authors present a case of interstitial pregnancy in a 29-year-old woman with no identifiable risk factors for ectopic pregnancy. Laparoscopic cornuostomy was successfully performed, involving the application of adrenaline and a cerclage suture around the interstitial pregnancy on the right side, followed by ipsilateral cornuostomy and salpingectomy. During the procedure, Fitz-Hugh-Curtis syndrome was diagnosed, which may have contributed to the occurrence of this ectopic pregnancy. Conclusion: Interstitial pregnancy is a rare condition that can lead to significant morbidity and mortality, particularly in cases of uterine rupture and hemorrhage. Diagnosing interstitial pregnancy is often challenging and may only occur during surgery. Therefore, early detection is vital to prevent a potentially life-threatening condition and facilitate conservative approaches, since the optimal treatment approach for interstitial pregnancy remains uncertain.
