Anatomic variations of the healthy colon | Fernando J, et al. 22 Actual Med.2022;107(815):18- 26 Analysis of morphometric variables by BMI When comparing the morphometric variables between the normal weight, overweight, and obese groups, respectively, statistically significant differences were found for the distances SMA - IMA (6.35 vs. 6.92 vs. 7.00 cm), PUBIS - HF (15.15 vs. 18.55 vs. 15.87 cm), PUBIS - ICJ (12.03 vs. 14.13 vs. 14.92 cm), PUBIS - SDJ (8.31 vs. 7.79 vs. 10.62 cm), SMA - SF (8.31 vs. 9.62 vs. 9.56 cm), IMA - HF (8.85 vs. 10.97 vs. 11.49 cm) and IMA - SF (11.86 vs. 13.89 vs. 13.50 cm), as well as the angle HF - IMA - SF (115.04º vs. 96.86º vs. 95.81º). A posteriori two-by-two contrasts were further applied to analyses the morphometric variables discussed above that showed statistically significant differences between these three groups. The distance SMA - IMA showed a statistically significant difference between the normal weight and obese groups. The distance IMA - SF showed a statistically significant difference between the normal weight and overweight groups. The distances PUBIS - HF, PUBIS - ICJ, SMA - SF and IMA - HF, as well as the angle HF - IMA – SF, showed statistically significant differences between the normal weight and overweight groups, as well as the normal weight and obese groups. Only the distance PUBIS - SDJ showed statistically significant differences between the normal weight and overweight groups, the normal weight and obese groups, and the overweight and obese groups (Tables 3-4).
