Abdominal Pregnancy in the Right Uterosacral Ligament: A Novel Case Report

Abdominal pregnancy is a rare type of ectopic pregnancy, accounting for about 1% of ectopic pregnancies. Early diagnosis of abdominal pregnancy is challenging and may lead to serious complications. This article reports a case of a patient who was 58 days postmenopausal and presented with acute lower abdominal pain. The patient's preoperative ultrasound suggested ectopic pregnancy. Laparoscopy and therapeutic surgery were performed. During the surgical procedure, the gestational sac was identified in the right uterosacral ligament, and the gestational tissue was successfully removed with minimal bleeding. Histopathological examination confirmed it to be chorionic tissue. The serum human chorionic gonadotropin level decreased significantly in the postoperative period, and she was discharged from the hospital on the fourth postoperative day. Abdominal pregnancies are rare and early diagnosis is crucial to prevent serious complications. Laparoscopic surgery is an efficacious treatment for early abdominal pregnancy.
