Fernando J, et al. | Anatomic variations of the healthy colon 23 Actual Med.2022;107(815):18- 26 Correlation analysis between age, BMI, and morphometric variables A positive and statistically significant correlation was found between age and the angle HF - PUBIS - SF (r = 0.328) and the distances SMA - HF (r = 0.241) and IMA - HF (r = 0.34); the correlation between age and the distance PUBIS - HF (r = 0.155) was close to statistical significance as well. The correlation with age was statistically significant but negative for the distances PUBIS - SMA (r = - 0.233) and PUBIS - IMA (r = - 0.245). A positive and statistically significant correlation was observed between BMI and the distances PUBIS - SMA (r = 0.232), SMA - IMA (r = 0.276), PUBIS - HF (r = 0.492), PUBIS - SF (r = 0.273), PUBIS - ICJ (r = 0.442), PUBIS - SDJ (r = 0.354), SMA - SF (r = 0.351), IMA - HF (r = 0.369), and IMA - SF (r = 0.319). The correlation with BMI was statistically significant but negative for the angle HF - IMA - SF (r = - 0.293) (Table 5). DISCUSSION Our study sought to demonstrate whether sex, age, and BMI influence the anatomy of the colon by using three-dimensional reconstructions of the colon from CT scans, further evaluating whether any potential changes could be measured and analyzed. The anatomical variability of the colon is well known in terms of the length of its segments and their different disposition. (2,3) Embryonic development explains this variability. The rotation of intestinal loops and the fusion of the peritoneal layers produced during the formation of mesenteries and fascial coalescence determine the location and length of the different colonic segments. (1,18) Moreover, recent anatomical studies have considered the mesentery as a distinct organ with continuity throughout the digestive tract, from the duodenum to the anorectal junction, which also influences the various morphologies observed in the colon.
