Cloacal exstrophy: individualized management through a staged surgical approach.
Cloacal exstrophy, centered on the maldevelopment of the primitive streak mesoderm and cloacal membrane, results in bladder and intestinal exstrophy, omphalocele, gender confusion, and hindgut deformity. The surgical management and outcome of 10 of 14 survivors (1965 to 1988) are described. Genotypic males (6) were assigned male (2) or female (4) phenotype. Genotypic females (4) were unchanged. All had omphalocele closure in the newborn period. Two had loop stomas. Eight had end stomas (ileostomy [6], ileocolostomy [2]). Toddler and adolescent reconstruction differed in each. Early in the study, abdominoperineal pull-through failed in four patients, necessitating permanent stoma. Four patients had a stoma from the outset. Augmentation using colon remnant improved water loss and nutrition in two infants. Exstrophy turn-in for urinary reservoir was considered in all, but was impossible in three who required urinary diversion. Six patients had exstrophy turn-in and now void by clean intermittent catheterization (4), continent vesicostomy (1), and incontinent (1). Hindgut augmentation improved urinary capacity in two. Two genotypic-phenotypic males had penile lengthening. Four genotypic male-phenotypic females had early orchiectomy with subsequent clitoroplasty or vaginoplasty. Four genotypic-phenotypic females had clitoroplasty or vaginoplasty. Cloacal exstrophy is compatible with a useful life and sound psychologic development, but requires staged reconstruction with long-term support and follow-up.
