The incidence of intestinal volvulus gleaned from the world's medical literature spread over the past seven decades supports the contention that this bowel disorder has distinct geographical predilections. Sigmoid volvulus, invariably superimposed upon a redundancy of this part of the bowel, probably results from a functional disturbance of the colon mediated perhaps by a high-residue vegetable diet. The same factors appear to hold for small bowel volvulus, though caecal volvulus occurs strictly on the basis of preexisting anatomical abnormalities.
从过去七十年间世界各地医学文献中收集到的肠扭转发病率数据支持了这样一种观点，即这种肠道疾病具有明显的地域倾向性。乙状结肠扭转总是发生在该段肠管冗余的基础上，可能是由高纤维蔬菜饮食介导的结肠功能紊乱所致。小肠扭转似乎也受同样因素影响，不过盲肠扭转则严格基于先前存在的解剖学异常而发生。
