First described by von Rokitansky in 1836, sigmoid volvulus (SV) refers to the wrapping of the sigmoid colon around its own base.1-3 The incidence of SV is relatively high in South Africa, the Middle East, Northern Europe, Latin America and Australia,1,3-6 but the incidence in the United states is 1.67 per 100 000 person-years.5 SV most commonly occurs in adult men and usually presents in the 4th to 8th decades of life; the male to female ratio ranges from 1.4/1 to 4/1.1,3,7 The presence of an elongated sigmoid colon with a narrow mesentery (dolichosigmoid) is a prerequisite for SV, which is thought to be related to advanced age, male gender, high altitude, dietary or defecation habits, and some pathologies such as megacolon.1,8
