Bicornuate uterus is a common symmetrical uterine malformation, the incidence of which accounts for approximately 13.6% of uterine malformations [1]. It occurs because during embryonic development, two paramedian ducts (also known as Müllerian ducts) fuse and the middle section is not completely absorbed, forming a cervix, two uterine cavities, a bifurcation of the upper part of the uterine cavity and the bottom of the uterus, and a tonoplast at the tip of the unabsorbed septum. 40% of bicornuate uteri can cause miscarriage, preterm labor [2], abnormal delivery, or infertility [3]. The fundamental treatment is to fuse the two narrow uterine cavities into one normal form. The traditional surgical approach is open uterine orthopedic surgery (strassman metroplasty). With the maturity and common use of combined hysteroscopic and laparoscopic surgery, a successful hysterolaparoscopic complete bicornuate uterine fusion was performed in our center in May 2007. The uterus is the site of fertilization and fetal growth and development, and abnormal uterine morphology and function is one of the causes of infertility, miscarriage, preterm delivery, IUGR or obstructed labor [4]. Bicornuate uterus is a symmetrical malformation of uterine development caused by hypoplasia of the paramedian duct. Surgical treatment can improve the morphology of the uterus, expand the uterine cavity, reduce intrauterine pressure, improve endometrial blood flow, facilitate fertilization and prevent miscarriage, and improve the reproductive prognosis [3, 5]. The aim of bicornuate hysterectomy is to restore fertility, and the procedure involves opening the uterine cavity, invading the endometrium, and postoperative scar formation, which may cause adhesions or stenosis of the uterine cavity and affect fertility. The traditional treatment is open orthopaedic surgery. in 1996 Pelosi et al [6] performed surgical correction using laparoscopy combined with a negative approach. Laparoscopic practice over the years has demonstrated that hysterolaparoscopic surgery is less invasive than open or negative surgery, with less tissue damage and a lower chance of postoperative intrapelvic adhesions []. In uterine orthopedics, hysteroscopic surgery has reasonably replaced open surgery, and Heinonen reported an increase in fetal survival rate from 13% to 91% in hysteroscopic orthopedics [5]. In recent years bipolar electrosurgery with the application of saline irrigation has been introduced to avoid hyponatremic complications and improve the safety of hysteroscopic surgery, Litta et al [6] compared the feasibility, safety and reproductive prognosis of unipolar and bipolar (Versapoint) hysteroscopic orthopedic procedures. In 63 patients with incomplete septum, 42 were corrected with bipolar and 21 with monopolar. The results were 20.5 min for unipolar and 15.4 min for bipolar, with P<0.05 for both groups. pregnancy, delivery and spontaneous abortion rates were similar in both groups. In this paper, we report a minimally invasive combined hysterolaparoscopic orthopedic bicornuate hysterectomy that significantly improves reproductive prognosis [7]. Recently Alborzi et al [8] reported 2 cases of laparoscopic correction after hysteroscopy of bicornuate uterus with good results. Combined hysterolaparoscopic correction of bicornuate uterus has good prospects for development. Figure 2 Figure 3.
