title: Anterior sagittal transanorectal approach to the urogenital sinus in adrenogenital syndrome: preliminary report.
abstract: In the female adrenogenital syndrome, the treatment of the urogenital sinus with high implanted vagina still presents a surgical challenge. The conventional technique (perineal vaginal pull-through) has been plagued by a high incidence of vaginal stenosis. A posterior sagittal transanorectal approach was proposed as an alternative to obtain an excellent exposure and thus an adequate mobilization of the vagina. But bivalving a normal rectum and anus has the potential for compromising bowel control and represents a bold maneuver, and the rectum and sphincteric mechanism must be meticulously reconstructed. In the original procedure a protective colostomy must be performed before the operation. To reduce these disadvantages, the authors made the following modifications: sagittal incision of only the anterior rectal wall (Anterior Sagittal Transanorectal Approach--ASTRA) and protective colostomy at the same time as the operation. In this way, maintaining the same excellent exposure and reducing the number of operations from three to two, we operated on 10 girls with adrenogenital syndrome: 4 with high, 3 with intermediate urogenital sinus, and 3 who had previously undergone vaginal pull-through but experienced a vaginal retraction with severe stenosis. At the time of surgery four patients were under 1 year (mean, 9.25 months) and six were from 2 to 11 years of age (mean, 6.5 years). After closing the colostomy, all patients were continent in stools and urine, and the vagina looked normal. The authors suggest using this modified approach as an alternative to the conventional operation and for those patients in whom other techniques have failed.
