| Abstrakt: | Purpose: We present a modified technique of sigmoid neovaginal construction in children that protects the sigmoid pedicle from traction, allows easy adjustment of caliber and reorients the mucosal fold in a longitudinal direction. Materials and Methods: From 1997 to 2000, 10 genetically male (46 XY) children 1 to 13 years old underwent construction of a neovagina with sigmoid, incorporating the Yang-Monti concept of intestinal reconfiguration. The diagnosis was androgen insensitivity in 7 patients, congenital adrenal hyperplasia in 2 due to 17 alpha-hydroxylase deficiency and 3 beta-hydroxysteroid dehydrogenase deficiency, respectively, and bladder exstrophy in 1 who required sex reassignment. Results: Eight children had an adequate caliber neovagina after an initial period of systematic dilation. In 1 case a relevant stricture required reoperation using the same technique and the outcome was good. In another child a stricture developed in the middle of the reconfigured sigmoid segment and a regular dilation schedule is still being followed after 23 months of followup. Conclusions: The new sigmoid reconfiguration technique enables the use of smaller dimension intestinal segments and construction of a long vaginal conduit of adequate caliber. Its optimal adequacy for penetration must be assessed in the future after these patients begin sexual activity. |
