All types of previous pelvic operations increase the risk of ectopic pregnancy from a 2-fold increase for appendectomy to a 9-fold increase for ectopic pregnancy, if maternal age, parity, history of spontaneous and induced abortions and history of infertility is controlled. This study suggests that a previous pelvic operation may increase the risk of ectopic pregnancy. ER -
