Septate uterusis a congenital anomaly that can cause abortion in a high percentage of cases.
The differential diagnosis usually is made with the 3D sonography but a preliminary laparoscopy can be useful to visualize the convexity or the concavity of the uterine fundus.
The resection is performed using an operative hysteroscope with monopolar cutting current and a straight blade ( Collins).
The procedure starts from the lower part of the septum and stops when the first vessels and the myometrium of the fundus are visible. A final laparoscopic view shows the change in the shape of the uterus.
