Spontaneous ectopic pregnancy occurring in the remnant tube after ipsilateral salpingectomy: a report of 2 cases.

Ectopic pregnancy occurring in the remnant tube after ipsilateral salpingectomy is assumed to be rare. We report 2 cases of spontaneous ectopic pregnancy occurring in the remnant tube that were treated surgically. Even in spontaneous pregnancy, attention should be paid to the remnant tube so as not to miss an ectopic pregnancy after previous salpingectomy.
