Bicornuate uterus is a common symmetrical uterine malformation, accounting for 13.6% of uterine malformations. 40% of bicornuate uteruses can cause miscarriage, preterm labor, abnormal delivery or infertility. The reason for this is that during the development of the embryo, the two paramedian tubes fuse and the middle part is not completely absorbed, forming a cervix, two uterine cavities, the upper part of the uterine cavity and the bottom of the uterus are bifurcated, and the end of the unabsorbed septum is rounded. If the septum is located in the middle part of the uterine cavity, it is an incomplete bicornuate uterus; if it reaches the endocervix, it is a complete bicornuate uterus. Patients with a history of more than two spontaneous abortions, or primary infertility of unknown origin and need for assisted reproductive technology are indications for bicornuate orthopedic surgery. Hysteroscopic surgery allows the removal of the intrauterine septa of the incomplete bicornuate uterus so that the thickness of the median muscle wall at the base of the uterus is the same as the rest of the uterine wall, thus restoring the uterine cavity to the maximum extent possible for treatment purposes. The traditional surgical method for the treatment of a completely bicornuate uterus is open orthopedic uterine surgery (Strassman Metroplasty), in which an incision is made in the midline of the uterine horns on both sides of the uterine base through open surgery until the uterine cavity is exposed, and then the incisions on the left and right sides are sutured longitudinally to form a normal uterus. It is not an ideal surgical method because of the high trauma and slow recovery after open surgery, and the transabdominal opening of the uterine cavity makes it very easy to form adhesions and scarring after surgery. With the advancement of hysteroscopic and laparoscopic techniques, Strassman Metroplasty has been reasonably replaced by combined hysteroscopic hysterotomy and fusion. 1996, Pelosi in the United States first reported hysteroscopic cathode-assisted complete bicornuate fusion, in which the hysteroscope is illuminated in the uterine horn to show the morphology of the uterine cavity, and the laparoscopic monopolar electro-needle wedge is used to dissect the uterus where the two horns are connected The tissue was removed from the posterior fornix, the uterus was repositioned after suturing the myometrial wall and the posterior fornix was sutured. In 2009, Xia Enlan et al. reported the first combined hysterolaparoscopic complete bicornuate uterine fusion in China. First, the intrauterine septum was incised with the hysteroscope, and the myometrial wall and plasma layer of the uterine fundus were incised to form an artificial perforation, and then the myometrial wall of the uterine fundus was incised transversely in the abdominal cavity to reach 37.5 px inside the uterine horn, and then both sides of the wound were sutured longitudinally to obtain a normal shape of the uterine cavity. This procedure allows for maximum restoration of the uterine cavity and meets the requirements of minimally invasive surgery. This patient has delivered two healthy female infants by cesarean section. In the same year, Alborzi et al. reported two cases of bicornuate uterus and two cases of bicornuate uterus with a history of two recurrent miscarriages, with good results in laparoscopic correction after hysteroscopy to identify the bicornuate cavity. Combined hysterolaparoscopic correction of bicornuate uterus has good prospects for development.
