Ischiopagus tetrapus conjoined twins: 22 years after separation

There is no record of both separated ischiopagus tetrapus conjoined twins leading normal lives 22 years after separation. We separated a pair of such twins in 1986 and have followed them up till date. Details regarding the technique of separation and the procedures required to ensure normal defecation and micturition and normal musculoskeletal function have been described by us in earlier communications. In this paper we describe their present status and ability to face the world as independent adult females. The outcome reflects the responsibilities and dedication of pediatric surgeons for infant patients with congenital problems after they have become adults, taking a pivotal role to involve surgeons of other disciplines as and when necessary
