腹腔鏡下異所性妊娠温存手術後に反復した痕跡子宮側卵管間質部妊娠

　Unicornuate uterus is a uterine malformation caused by Müllerian duct dysplasia and is classified according to the presence or absence of accessory horns, atrophic uterine remnant, and functional endometrium. Early diagnosis and treatment of rudimentary horn pregnancies are important because of the risk of serious perinatal complications involved.

　Transperineal transmigration of sperm, the ovum, and fertilized ovum can occur in spontaneous pregnancies and is responsible for many occurrences of rudimentary horn pregnancies and adnexal tubal pregnancies in the rudimentary horn. Even in the absence of a functional endometrium, adnexal tubal pregnancies can result from extravasation, making it important to select a curative treatment aimed at recurrence prevention.

　We described herein a case of repeated atrophic uterine interstitial pregnancy following conservative surgery which was able to be treated laparoscopically.
