[Feminizing genitoplasty in adrenal congenital hyperplasia: one or two surgical steps?]. / Genitoplastia feminizante en hiperplasia suprarrenal congénita; una o dos etapas quirúrgicas?

SUMMARY OBJECTIVES: The best time to perform a genitoplasty in a Congenital Adrenal Hyperplasia (CAH) girl is an issue that has been discussed extensively. The purpose of this study is to find criteria that may help in the decision. METHODS: Charts of all patients with diagnosis of CAH with 21 Hydroxylase deficit who underwent genitoplasty in our institution were reviewed (Jan 1996-Dec 2006). Demographic data, surgery performed and outcomes were analyzed. RESULTS: In the 10 year-period, 25 patients fit the inclusion criteria; 22 had complete data. All patients were classified based on Prader's criteria; Prader 2 (n=3), Pra der 3 (n=13) and Prader 4 (n=6). Mean age at first surgery was 13.5 months (range 2-89 m). In Prader 2 patients, a reduction clitoroplasty with a "cut back" vaginoplasty was performed with no complications. All patients in the Prader 3 group underwent a reduction clitoroplasty. A vaginoplasty was done in 9/13; 5/9 at the same surgery session (4 stenotic) and the other 4 in a 2nd stage with good results; vaginoplasty is still pending for the other 4 girls. In the Prader 4 group, a vaginoplasty pull-through was performed in 4/6 using the posterior sagital approach; one at the reduction clitoroplasty stage which ended stenotic and need dilatations, and the other 3 in a 2nd surgery with a good outcome. The other 2/6 girls are awaiting a vaginoplasty. 22/22 had acceptable results after a mean follow-up of 63 months (range 12-144). CONCLUSIONS: Congenital Adrenal Hyperplasia (CAH) shows different approaches may be used for different degrees of virilization. For less severe cases (Prader 3) a cut-back may be the surgery of choice for vaginoplasty, while in the more complex cases a flap with pull-through or a posterior sagital procedure could be useful. Based on this series, we recommend performing vaginoplasty in a 2nd stage surgery, avoiding complications and further procedures such as di lactations.

Genitoplastia feminizante en hiperplasia suprarrenal congénita; ¿una o dos etapas quirúrgicas? / Feminizing genitoplasty in adrenal congenital hiperplasia: One or two surgical steps?

OBJETIVO: El mejor momento para realizar una genitoplastia en una niña con Hiperplasia Suprarrenal Congénita (HSRC) es un tema que ha sido debatido ampliamente. El objetivo de este estudio es encontrar un criterio que pueda ayudar en esta decisión.MÉTODO: Se revisaron los datos de todos los pacientes con diagnóstico de HSRC con déficit de 21 Hidroxilasa que se sometieron a genitoplastia en nuestra institución (Enero 1996-Diciembre 2006). Se analizaron datos demográficos, cirugía realizada y resultados.RESULTADOS: En el periodo de 10 años, 25 pacientes cumplieron los criterios de inclusión; 22 tenían datos completos. Todos los pacientes fueron clasificados basándose en los criterios de Prader; Prader 2 (n=3), Prader 3 (n=13) y Prader 4 (n=6). El promedio de edad al momento de la primera cirugía fue 13.5 meses (rango 2-89m). En los pacientes Prader 2, una clitoroplastia de reducción con una vaginoplastia “cut back” fue realizada sin complicaciones. Todos los pacientes del grupo Prader 3 se sometieron a una clitoroplastia de reducción. Una vaginoplastia fue hecha en 9/13; 5/9 en la misma sesión quirúrgica (4 estenóticas) y los otros 4 en un segundo tiempo, con buenos resultados; en las otras 4 niñas la vaginoplastia está aún pendiente. En el grupo Prader 4, una vaginoplastia “pull-through” fue realizada en 4/6 usando un abordaje sagital posterior; uno al momento de la clitoroplastia de reducción, con resultados estenóticos y necesidad de dilataciones, y los otros 3 en una segunda cirugía con buenos resultados. Las otras 2/6 niñas están esperando una vaginoplastia. 22/22 tiene resultados aceptables luego de un periodo de seguimiento de 63 meses (rango 12-144m)(AU)

CONCLUSIONES: La Hiperplasia Suprarrenal Congénita (HSRC) muestra diferentes grados de virilización, por lo tanto distintos abordajes pueden ser utilizados. Para los casos menos severos (Prader <3) un “cut-back” puede ser la cirugía de elección para una vaginoplastia, mientras en los casos más complejos un colgajo con “pull-through” o un procedimiento sagital posterior puede ser útil. Basado en esta serie, nosotros recomendamos realizar una vaginoplastia en un segundo tiempo quirúrgico, evitando complicaciones y procedimientos adicionales como las dilataciones(AU)
