Colonic duplication is a rare congenital anomaly that is often diagnosed in childhood, but may go unrecognised until adulthood. It often presents with chronic abdominal pain and constipation, and the preoperative diagnosis may be difficult. We present a case of sigmoid duplication in a 33-year-old Indonesian woman who presented with right-sided colicky abdominal pain and vomiting. Clinical examination was unremarkable and radiological investigations raised the possibility of a giant colon diverticulum. The patient underwent exploratory laparotomy that revealed a tubular sigmoid duplication. A sigmoid colectomy with end-to-end anastomosis was performed. She was discharged a week later and remained well at 1 year follow-up. Colon duplications rarely present in adult life and the accurate diagnosis is often made at laparotomy.
