Abstract：Objective To study the risk factors and clinical features of recurrent tubal ectopic pregnancy (REP).Methods A retrospective case-control study was performed in 78 REP and 77 single ectopic pregnancy (SEP)patients matched at a ratio of 1 ∶ 1 with respect to age of initial EP,marital and employment status between January 2013 to December 2014 from Peking Union Medical College Hospital.Results Nonparous women (OR=2.163,95％CI 1.066-4.386) and previous laparotomy surgery for initial EP patients (OR=8.585,95％ CI 1.001-73.596)were more likely to suffer REP.Clinical features were similar between REP and SEP,except that REP patients had less adnexal mass ＞ 4cm on ultrasound (P＜0.01).Surgical findings showed that REP had more pelvic adhesion and contralateral tubal disorders (P＜0.05).Conclusion Active prevention for primary EP,effective contraceptive methods and laparoscopic surgery are proposed to reduce the risk of REP.
