Parapagus conjoined twins: Complicated anatomy precludes separation

A parapagus set of male conjoined twins was brought to our institution at 12 h after birth. An extensive sharing of the abdominal viscera (single liver, hindgut), abdominal aorta, pelvis (single rectum and anus), genitalia (one set) and vertebral column was found. The surgical separation was not considered due to medical and ethical issues.
