Laparoscopic management of 4 cases of recurrent cornual ectopic pregnancy and review of literature.

The objectives of this retrospective case series were to report our experience with laparoscopic management of recurrent cornual ectopic pregnancy in a tertiary care center and to present a review of the literature. Four patients experienced recurrent cornual ectopic pregnancy, and 1 patient had 2 consecutive recurrences. Laparoscopic surgery was performed to treat recurrent cornual ectopic pregnancy in all 4 patients. These 4 cases together with 10 cases collated from the literature review confirm that this entity is rare. Cornual ectopic pregnancy can recur as early as 4 months and as late as 5 years after the first ectopic pregnancy. There seems to be no correlation between the treatment method of the first ectopic pregnancy and the risk of recurrence. The etiology of recurrent cornual ectopic pregnancy is not fully understood, although it shares similar risk factors with tubal ectopic pregnancy. Both medical therapy and surgery are used to treat recurrent cornual ectopic pregnancy, with surgery often performed via laparotomy. These 4 cases constitute the largest case series of recurrent cornual ectopic pregnancy treated laparoscopically. Our experience with laparoscopic management of recurrent cornual ectopic pregnancy in a tertiary care center reveals that it is effective and safe.
