“…The length of the large intestine has been measured by several researchers [110,111,112,113,114,115,116,117,118,119], but it is difficult to compare these data because of differences in the methods of measurement employed. Western reports generally use two methods, i.e., measuring the distance of string from mouth to anus, and by postmortem survey [112,113,114,115,116,117,118,119]; in contrast, Japanese reports determine the length of the large intestine by radiographs with barium enema [110,111]. As mentioned above, Sugihara et al [105] and Sasaki et al [107] have suggested that intraluminal pressure causes the development of right-sided diverticula in Japan.…”
