Tubal stump pregnancy after salpingectomy-Does the time interval from surgical intervention to conception matter?

Aim: Ectopic pregnancy implantation on the tubal stump after salpingectomy is a rare location for extrauterine pregnancy, whose pathogenesis is still unknown. The purpose of this study was to examine whether the time interval elapsed from salpingectomy may predispose the embryo to implantation on the tubal stump in the next pregnancy subsequent to tube removal.

Methods: Nine women operated for stump pregnancy (study group) between 2008 and 2019 were retrospectively identified.
