Ileosigmoid knotting

Abstract

Ileosigmoid knotting carries a significant risk of mortality, and sigmoid resection should be considered for all patients with this unusual condition.

Ileosigmoidal Knotting: Outcome in 63 Patients

“…[1][2][3][4][5][6] Its incidence in the general population is not known, 4,6 but it is high in Turkey especially in eastern Anatolia. 1,2 Although ISK accounts for 18 to 50 percent of all sigmoid colon volvulus cases in eastern and 5 percent in western countries, 1,2 our rate is 7.6 percent.…”

“…ISK is common in adult males, and the peak incidence, as in our experience, is in the fourth decade. [1][2][3][4] To explain the development of ISK, some anatomic predisposing factors are considered. These include a hypermobile small intestine and cecum with an elongated mesentery having a narrow base and a redundant sigmoid colon with a long mesocolon having a narrow base.…”

The Unusual Volvulus : A Five Year Retrospective Analysis of Nine Cases

“…Ileosigmoid knotting (sometimes referred to as double or compound volvulus) is an unusual form of intestinal obstruction found mainly in parts of the world where sigmoid volvulus is common [1]. Unfamiliarity with this condition can have disastrous consequences at surgery [2].…”

Ileal invagination of the sigmoid colon producing a sigmoidorectal intussusception combined with rectal prolapse in a 3-year-old child

“…Ileal invagination of the sigmoid colon leading to sigmoidorectal intussusception is a rare disease entity unlike ileosigmoid knotting, which is relatively common in certain African, Asian, and Middle Eastern countries [1][2][3][4]. A search of the world literature (including a Medline search) revealed no cases in children of sigmoidorectal intussusception in combination with an ileal invagination into the sigmoid colon together with a rectal prolapse.…”
