title: Spontaneous live recurrent ectopic pregnancy after ipsilateral partial salpingectomy leading to tubal rupture.
abstract: BACKGROUND
  Ectopic pregnancy accounts for 1-2% of all pregnancies in the United States. The most common site of implantation for an ectopic pregnancy is the fallopian tube. We present the first case describing a recurrent ectopic pregnancy with a fetal heartbeat after ipsilateral salpingectomy that led to tubal rupture.
  
  
  METHODS
  The patient presented with abdominal pain approximately six weeks after her last menstrual period. Seven years prior to presentation, a laparoscopic partial right salpingectomy had been performed for a tubal ectopic pregnancy. Physical exam was significant for diffuse abdominal tenderness and guarding. Ultrasonography revealed a right tubal pregnancy with a fetal pole and a fetal heart rate that was calculated to be 108 beats per minute. Free fluid was also noted. 1.5l of hemoperitoneum was subsequently evacuated and the right fallopian tube remnant with the ectopic pregnancy was removed. Pathology of the tubal remnant showed immature chorionic villi and fetal parts.
  
  
  CONCLUSIONS
  The mechanism by which a recurrent ectopic pregnancy after ipsilateral salpingectomy occurs is unclear, but is theorized to be secondary to contralateral fertilization and/or tubal recanalization that may occur due to inadequate diathermy.
  
  
  CONCLUSIONS
  Physicians should be aware that ectopic pregnancies may not only occur repeatedly but may also present a typically. We recommend when performing a salpingectomy that efforts be undertaken to minimize the length of the tubal remnant and to assure adequate coagulation of tissue so as to reduce the risk of recurrence.
