Rectosigmoid vaginoplasty: clinical experience and outcomes in 86 cases

There are several techniques for creation of a neovagina. However, rectosigmoid segment presents the most natural substitute for vaginal tissue.

To evaluate the anatomical and functional results of sigmoid vaginoplasty and long-term sexual and psychological outcomes in 86 patients with vaginal absence.

Between April 2000 and February 2009, 86 patients, aged 18 to 57 years (mean 22) underwent rectosigmoid vaginoplasty. Indications were vaginal agenesis (54), female transgenderism (27), and genital trauma (5). Rectosigmoid segments ranging from 8 cm to 11 cm were isolated, to avoid excessive mucus production. Preferably, it should be dissected distally first in order to check its mobility and determine the correct site for its proximal dissection. Stapling device was used for the colorectal anastomosis as the safest procedure. Creation of perineal cavity for vaginal replacement was performed using a simultaneous approach through the abdomen and perineum. Perineal skin flaps were designed for anastomosis with rectosigmoid vagina for the prevention of postoperative introital stenosis. Main Outcome Measures.  Sexual and psychosocial outcomes assessment was based on the Female Sexual Function Index, Beck Depression Inventory, and standardized questionnaires.

Follow-up ranged from 8 to 114 months (mean 47 months). Good aesthetic result was achieved in 77 cases. Neovaginal prolapse (7) and deformity of the introitus (9) were repaired by minor surgery. There was no excessive mucus production, vaginal pain, or diversion colitis. Satisfactory sexual and psychosocial outcome was achieved in 69 patients (80.23%).

Rectosigmoid colon presents a good choice for vaginoplasty. According to our results, sexual function and psychosocial status of patients who underwent rectosigmoid vaginoplasty were not affected in general, and patients attained complete recovery.
