A Rare Coexistence: Omphalomesenteric Remnant with Appendix and Caecum Duplication

The nutrition source of developing embryo at early stages is the omphalomesenteric duct which obliterates latter. Failure of this obliteration process brings on omphalomesenteric remnants. Appendix anomalies, which include appendix duplications, are very rare. Usually severe intestinal, genitourinary and vertebral anomalies coexist with appendix duplications. The aim of this study is, to present a case of an infant who underwent surgery for operative repair of an omphalomesenteric remnant (omphalomesenteric fistula), and appendix and caecum duplication was diagnosed during surgery, to review the classification of appendix duplications and to call attention to coincidence of omphalomesenteric remnants and other congenital anomalies.
