To demonstrate an easier surgical strategy by using the marking technique for hysteroscopic incision of the uterine septum using 5-French cold scissors.
A step-by-step surgical video demonstration.
Gynecologic department of the affiliated hospital.
A 33-year-old woman presented with a 4-year history of primary infertility. She previously had undergone transcervical resection of (uterine) septum owing to the presence of a complete uterine septum and double cervices. Postoperative 3-dimensional ultrasound revealed a 1.2-cm residual uterine septum, and the outline of the uterine fundus was flat. A second surgery for resection of the residual septum was recommended before in vitro fertilization and embryo transfer. We used the Campo hysteroscope (4.4-mm outer sheath) and 5-French scissors with our modified marking strategy to incise the incomplete uterine septum.
There were several critical strategies for this approach. After fully exposing 2 fallopian tube ostia, a 3–5-mm mark was made on each side of the uterine fundus where the septum ended, and the marks were parallel to the fallopian tubal ostia. The septum then was incised along the line between the two previously marked points that served as the endpoints. Care was taken to avoid incising myometrial blood vessels during incision, and the 5-French bipolar electrode was used for coagulation when necessary. At the end of the surgery, the distension pressure was gradually decreased to 80 mm Hg to confirm hemostasis of the wound before withdrawing the hysteroscope.
Main Outcome Measure(s)
Description of a modified hysteroscopic technique.
The overall operation time was 10 minutes, and the estimated blood loss was 5 mL. The residual septum was resected successfully while maintaining optimal hysteroscopic visualization. There were no short-term complications, such as uterine perforation or fluid overload. Hysteroscopic evaluation performed 3 months after surgery revealed that the uterine cavity was nearly normal, with no intrauterine adhesion appreciated. There are several advantages to this innovative and practical hysteroscopic surgical approach. Marking the lateral limits of the uterine septum means that a shorter reference line is obtained to incise the septum effectively rather than using the bilateral ostia as reference points. At the same time, marking the bilateral endpoint of the uterine septum incision at the beginning of the surgery might be helpful when bilateral tubal ostia are invisible because of quick absorption of the distension media, which causes insufficient distention pressure at the end of the surgery. Use of the narrow 5-French scissors allowed for instrumentation without prior cervical dilation. Moreover, with this “see and treat” strategy, a clear visualization of the surgical field was maintained without inserting and withdrawing the hysteroscope. The endometrium sustained minimal damage because of the “cold scissors” technique.
Our hysteroscopic marking strategy allows the surgeon’s intraoperative judgment to be efficient and safe during incision of the uterine septum and ensures that the incision is adequate. It is an improved and valid surgical strategy for hysteroscopic incision of the uterine septum.
