In the initial hysteroscopic examination, we noticed that there was a blue line along the septum on the midline of the endometrial cavity traversing between the two tubal ostia after the injection of methylene blue. Then, we used this blue line as a guide to determine the line of incision and we incised the septum just along it. We presented two of these cases with a new finding, which we named the “Süha-Levent sign”. As a result, we believe that this finding might be used as a useful marker before incising the septate uterus.

Hysteroscopic incision of the septum is the gold standard in the treatment of cases of a septate uterus [1–3]. Determination of the incision line and depth are the most important parts of the hysteroscopic septum incision. Complications (such as perforation or incomplete incision) due to incorrect incision are not rare . Septum incision is performed with an incision between the two tubal ostia on the midline. The depth of incision reaches to a level at which both of the tubal ostia could be seen on the same plane. But it is an imaginary line and it is not always easy to determine the midline because of the angled optical system and intraoperative bleeding. Determining the incision line can cause some confusion in the mind of a surgeon, especially one who is at the beginning of his training program.
Uterine septum (Class Vb according to AFS Classification for Mullerian Duct Anomalies) was diagnosed in a 32-year-old, gravida 1, abortus 1, Caucasian woman with normal hormone profile and bilateral tubal occlusion on hysterosalpingography. She had undergone laparoscopy and hyteroscopic septum incision (Fig. 1b). Severe pelvic adhesions and occlusion at the middle portion of the right tube and left hydrosalpinx were determined by laparoscopic exploration. Laparoscopic left salpingectomy for hydrosalpinx and proximal cauterization on the right tube were performed. We saw a blue line 2–3 mm in width through the hysteroscope just on the midline of the endometrial cavity, the same as mentioned in first patient (Fig. 2b). A 2-cm deep septum incision was performed by a hysteroscopic monopolar resector along the blue line, under laparoscopic supervision (Fig. 3b). We completed the operation without complication and the patient was discharged the following day.
Generally, it is easy to determine the incision line during the hysteroscopic treatment of a septate uterus. It may be problematic when the surgeons at the beginning of their training program or if another pathology or abnormality exists in the endometrial cavity. The Süha-Levent sign can help to determine the incision line. This sign was described first by Levent Yasar and was first presented by Süha Sönmez in a national congress, and then it was named as the “Süha-Levent sign.” We postulated that this appearance may be due to the high-speed jet or turbulence of dye in the top or the deepest area of the uterine cavity when injected by a cannula (Rubin’s cannula) through the cervical canal. The deepest region in the endometrial cavity is the zone that holds the methylene blue. The zone which holds the methylene blue is the zone where the flashing dye strikes vertically and the dye penetrates the endometrial epithelium and glands. In this way, we could make a simple hypothetical explanation for the reason why this line occured in this zone. We don’t exactly know reason why the area at the top of the uterine cavity holds methylene blue. Süha-Levent’s sign can also depend on cellular, histologic, or molecular abnormalities in the defective epithelium covering septum [4, 5]. We have seen this sign even in cases with patent or occluded tubes. For now, we have only presented our observations on two cases, but soon we will present the full results of our clinical study. It is necessary to perform histologic, molecular, or clinical studies on this subject, as it may have a multifactorial etiology.
The findings presented in this report may shorten the training time for the hysteroscopic incision of the uterine septum. Methylene blue injection just before hysteroscopic septum incision can help to identify the right incision line on the uterine septum. One can make an incision accurately on the line that holds methylene blue.
