PURPOSE: No consensus exists regarding the most effective procedure for neovagina formation. We describe our experience with modified single Monti tube colovaginoplasty in pediatric patients with disorders of sexual differentiation.
MATERIALS AND METHODS: Six patients were retrospectively identified who underwent primary sigmoid vaginoplasty with a modified single Monti tube between 2009 and 2012. Data were collected from patient charts. The procedure is performed by isolating an 8 to 10 cm segment of distal sigmoid colon or proximal rectum, which is detubularized along the anterior mesentery, folded and retubularized longitudinally, leaving the mesentery in a cephalad position. A channel is dissected in the pelvis to accommodate the neovagina.
RESULTS: Mean patient age was 12.7 years (range 6 to 17). The primary diagnosis was androgen insensitivity in 3 cases (50%), and Mayer-Rokitansky syndrome, partial androgen insensitivity and persistent cloaca in 1 each (16.7%). Chromosomal analysis revealed 46XY in 4 patients (66.7%). Median followup was 7.9 months (range 3 to 41). One patient who engages in vaginal intercourse reported satisfactory vaginal length without discomfort. In 1 patient an anastomotic stricture developed, which was managed by buccal mucosal grafting.
CONCLUSIONS: Modified single Monti tube sigmoid vaginoplasty is a safe, effective technique for neovagina formation in pediatric patients with disorders of sexual differentiation. Compared to other existing methods, our technique allows for the use of shorter bowel segments with decreased tension of the vascular pedicle.
