A rare case of extraluminal interstitial pregnancy treated with laparoscopic cornuotomy

Abstract

AbstractWe report an extremely rare case of an extraluminal interstitial pregnancy. A 36‐year‐old nulliparous woman visited our hospital during the fifth week of gestation. Although no intrauterine gestational sac (GS) was identified, transabdominal ultrasonography revealed a GS‐like cyst was detected in the right uterine horn. She underwent laparoscopic surgery for a suspected interstitial ectopic pregnancy. After laparoscopic cornuotomy, dye leakage was observed from the fimbria rather than the incision site. Finally, the patient was diagnosed with a right extraluminal interstitial pregnancy. Hysterosalpingography performed at three postoperative months revealed bilateral tubal passage. She conceived 7 months after surgery, with safe delivery by elective cesarean section at 38 weeks.
