A case of bicornuate uterus in that the ectopic cervical gland was simultaneously removed during total laparoscopic hysterectomy

Abstract

　The incidence of uterine malformations in the general female population is estimated to be 3.8% to 6.7%. From the 8^th week of gestation, the oviduct, uterus, and upper vagina are formed by the differentiation of the Müllerian ducts, but a cessation of differentiation during this process results in uterine malformations. The uterine morphology is classified into duplicated uterus, bicornuate uterus, septate uterus, and so on, starting from the condition resulting from the earliest differentiation arrest. In this report, we describe a case in which a patient was diagnosed with a single cervical bicornuate uterus at the time of pregnancy and delivery and underwent total laparoscopic hysterectomy for excessive menstruation and anemia due to submucosal fibroids.
