The normal position of the anus is not defined objectively. Using a simple technique, the anal position index was designed to define the position of anus in neonates and infants as follows: the ratio of the distance between the scrotum and the anus to the distance between the scrotum and the coccyx for males and the distance between the vagina and the anus to the distance between the vagina and the coccyx for females. The anal position index in neonates was not affected by body weight. In male infants, the anal position index was not affected by age. But in female infants, the anal position index decreased from neonatal period to three months of age but no significant difference was demonstrated from three months of age to twelve months of age. We think that the anal position index is useful as an objective parameter to assess the localization of the anus.

Case 1. A full term male infant was admitted on the day of birth with an associated omphalocele, spina bifida, extrophy of the bladder, imperforate anus and cecal fistula. 3 months after birth, a colostomy was created at the perineal portion. At 3 years of age, the patient underwent a total cystectomy and ileocutaneous ureterostomy. This 7 years old boy is now healthy and is leading active life. Case 2. A premature male infant was admitted on the day of his birth with an omphalocele, extrophy of the bladder, imperforate anus and cecal fistula. An intravenous pyelogram revealed bilateral double pelvis and double ureter. 4 months after birth, a colostomy was created at the perineal portion. At 2 years of age, an ileocutaneous ureterostomy was created at the left lower abdomen. This patient is now 5 years old and is healthy and active. The use of extrophied colon is contributory for the success. Colostomy was created at the perineum, in spite of all the defect of muscles in that place. Iliac osteotomies are not necessary in order to close the abdominal wall. It may be stressed that successful surgical management was achieved by employment of staged procedure.
