Sigmoid volvulus occurs more frequently in the younger patient than is presently thought. It is not infrequent in females. It usually presents with "colicky" abdominal pain, long-standing constipation or obstipation, and increasing distention of several days' duration. A history of similar attacks strengthens the suspicion for this diagnosis. Abdominal x-ray films will usually reveal severe colonic dilation down to a low point in the sigmoid, without gas in the rectum. The classic "horseshoe" sign is seldom seen, but when present, strengthens the diagnosis. Surgical manipulation and pregnancy may be contributing factors. Treatment should be surgical unless contraindicated by specific circumstances.
乙状结肠扭转在年轻患者中的发生率比目前认为的更高。在女性中并不少见。它通常表现为“绞痛性”腹痛、长期便秘或完全性便秘，以及持续数天的腹胀加重。类似发作的病史会增加对此诊断的怀疑。腹部X光片通常会显示严重的结肠扩张至乙状结肠的最低点，直肠内无气体。经典的“马蹄形”征象很少见，但出现时有助于诊断。手术操作和妊娠可能是促成因素。除非有特殊情况禁忌，否则应进行手术治疗。
