Despite its great importance in surgical approaches to intestinal resection, little definitive information is available on human gut tract length. Previous studies have correlated various measures with sex, age, weight, height, and “ethnic background.” Better knowledge of these relationships may aid in avoidance of surgical complications such as the nutritional disorder “short bowel syndrome.” This study examined length of the intestinal tract and its components (small intestine and colon) in 10 donor bodies. The small intestine was measured from pyloric sphincter to ileocecal junction while the large intestine was measured from caecum to sigmoid colon. Results indicate strong correlation (r=0.827) between colon length and body height from cranial vertex to heel, likely a result of the colon's function in water absorption. This relationship was stronger than the ones among total gut length, small intestine length, and body height. In particular, the weakest correlation was between small intestine length and height (r=0.337), suggesting that the combined lengths of the duodenum, jejunum, and ileum are not closely related to body size. Indeed, this measure had the highest coefficient of variation (0.26) while colon length showed the lowest (0.085). Future research will test hypotheses related to population differences in gut length and its physiologic consequences.
