Translevator anal anomalies with cutaneous fistulae passing deep to the scrotum.

METHODS

The authors present a series of 9 patients collected from 4 centers with translevator anal anomalies, each of which has a fistula tracking forward deep to the scrotum and opening at the peno-scrotal junction. Whereas some would appear to be covered ani in type, others are deeper and would appear to fit in with an intermediate type of classification emphasizing the idea of a "spectrum" of malformation.

RESULTS

The anatomic arrangement, associated anomalies (eg, 2 had hypospadias), and surgical management is described briefly in each case. Careful examination may be necessary to identify the fistula.

CONCLUSIONS

It is recommended that the surgery be individualized depending on the findings. On a theoretical embryologic basis there is abnormality in the formation of the outer genital folds, and there also may be abnormality in some cases of the inner genital folds.
