Conjoined twins can be subdivided into (a) symmetrical conjoined twins, and (b) heteropagus or parasitic twins. This chapter presents a brief summary of the history of conjoined twins followed by a classification of the various types according to the site of attachment, the investigations required, and the operative procedure. The experience of the team at Great Ormond Street Hospital is presented.
