The incidence of the ileal band was recorded in 1,040 northwest Indian subjects varying in age from 1 day to 100 years on whom a medicolegal postmortem had been performed by the author. The band was present in 31.8% of male and 17.5% of female subjects (P less than .05) and was either quadrilateral (60%) or triangular in shape. In addition 25 foetuses, each above 250 mm in crown-rump length, 25 neonates, 25 monkeys (Macaca mulatta), and an equal number of dogs, rabbits, guinea pigs and rats were also dissected, but the band was found to be absent. In all the foetuses dissected and in 24 out of 25 newborns the caecum was found to be either in the subhepatic or right lumbar region. The earliest age at which the band was found was 7 months. As the band was absent in the animals and the newborns, it appears that it develops in man on account of attaining an erect posture.
作者对1040名年龄从1天到100岁不等的印度西北部受试者进行了法医尸检，并记录了回肠带的发生率。该回肠带出现在31.8%的男性和17.5%的女性受试者中（P<0.05），其形状为四边形（60%）或三角形。此外，还解剖了25例冠臀长超过250毫米的胎儿、25例新生儿、25只猴子（恒河猴），以及数量相等的狗、兔子、豚鼠和大鼠，但未发现回肠带。在所有解剖的胎儿以及25例新生儿中的24例中，发现盲肠位于肝下或右腰区。发现回肠带的最早年龄为7个月。由于在动物和新生儿中未发现回肠带，似乎它是人类因采取直立姿势而发育形成的。
