Vaginectomy is surgery with limited indications. Usually, it is performed with concurrent hysterectomy even if the uterus is not affected by the neoplastic disease. However, it is possible to spare the uterine corpus and connect it to a neovagina. We present a nulliparous patient with vaginal melanoma and describe this step-by-step procedure. Written informed consent was obtained from all subjects.
The surgery proceeded as a radical abdominal trachelectomy1 except that there was no need for extensive parametrectomy. Epinephrine (1 mg) diluted in the saline solution (200 mL) was used to facilitate vaginal dissection.
After vaginal dissection up to its distal portion, two mixter forceps were used to clamp the distal border of the vagina, and the incision was made distally to it (Figure 1).
The proximal incision was made on the uterine cervix sparing 1 cm of it, close to the uterine isthmus, and a cervical cerclage was performed.
A foley catheter was attached to the uterine corpus to guide the neovagina pathway.
There are different possibilities to construct a neovagina (Online Supplemental Table 1), from the colon to abdominus myocutaneous flap, but we decided to use an ileal conduit to minimize the possibility of anastomosis fistula and because her mesocolon was too short.2–4 An ileal segment was carefully chosen, regarding its blood supply and it was sutured to the uterine corpus. After that, the distal end of the neovagina was sutured to the distal vagina and the round ligaments were reconnected.
The ileal anastomosis was performed using the Barcelona technique, in which a lateral-lateral entero-anastomosis is made by a stapler creating a common channel, and then, the same stapler is used to close the opening of this common channel.
Surgery time was 630 min and estimated blood loss was 400 mL. The foley catheter used to guide the neovagina came out by itself on the 10th post-operative day (Video 1).
The pathology report confirmed mucosal melanoma and margins were negative as well as lymph nodes.
Magnetic resonance on late postoperative term demonstrated a good location of the neovagina, and she resumed regular menstrual activity.
Regarding bladder activity, she had some occasional urinary incontinence after surgery that recovered with physiotherapy. The bladder foley catheter was removed on the 24th postoperative day.
On the 140th postoperative day, PET-CT evidenced positive sacral and iliac lymph nodes, and later, she presented nodules in the lungs, neck, and retroperitoneal space. She is under combined immunotherapy (Ipilimumab 1mg+nivolumab 3 mg every 21 days).
We conclude that it is possible to remove almost the entire vagina with uterine sparing and acceptable transitory bladder dysfunction.
