Twin ectopic pregnancy after ipsilateral salpingectomy: A report of cases

Abstract

Background: Ectopic pregnancy continues to be a significant cause of maternal morbidity and mortality. Recurrent ectopic pregnancy in the remnant portion of the tube after a previous ipsilateral salpingectomy has only rarely been reported. We present unusual cases of ipsilateral ectopic pregnancy occurring in the stump of an ectopic site. Cases report: Case 1. A 30 years old, gravida 2 para 0, she got pregnant after in vitro fertilization and embryo transfers, Diagnosed as a case of right twin ectopic pregnancy at the tubal stump of a previous partial salpingectomy caused by a ectopic pregnancy six months ago, treated by laparoscopic resection of stump.Case 2. A 29 years old, gravida 4 para 1. She had a recurrent right ectopic pregnancy at the stump of a previous salpingectomy done for ectopic pregnancy one year earlier, treated with methotrexate. Conclusion: Ectopic pregnancy in the remnant tube is difficult to diagnose due to the unique anatomic location of the pregnancy sometimes results in delayed diagnosis. Clinicians should be aware that salpingectomy does not exclude ipsilateral ectopic pregnancy. Although complete tubal resection cannot prevent cornual pregnancy, it might reduce the risk of recurrent ectopic pregnancy in the remnant tube.
