Sigmoid volvulus occurs when the sigmoid colon twists on its mesenteric pedicle. Anatomic factors predisposing to sigmoid volvulus include sigmoid redundancy and an elongated mesenteric pedicle. Adverse sequelae include obstruction, ischemia, and perforation. Without surgery, recurrence is common. Surgical options include stenting and sigmoid resection with or without restoration of bowel continuity.
