Concepts and considerations for repair of a severe cloacal anomaly

A 1.8 kg chromosomally normal child was suspected antenatally to have a cloacal anomaly and oligohydramnios. Both parents had a chromosome 9 inversion (inv [9] [p11 q13]). Postnatal study showed a high confluence of the urinary, genital and intestinal tracts. Because of prematurity, a right colostomy was performed on a short colon, but the genitourinary tract was not drained. Poor weight gain, urinary tract infection and septicaemia led to a one-stage reconstruction at 5 months of age and a weight of 3.2 kg. Follow-up although short at 15 months, is encouragingly suggestive of urinary and faecal continence. The vagina is patent. This paper considers concepts in cloacal management and submits for evaluation an alternative surgical plan to the presently almost exclusively accepted posterior sagittal approach of Pena and De Vries.
