A study on the morphology of the transition between the small and large intestines was carried out in 32 wild boars (Sus scrofa, L., 1758) genetically chosen, male and female, with ages averaging from young (4 months) to adult (14 months). We examed at macroscopic level all the specimens the shape and direction of the ileal prominence into the large intestine, of the ostium ileale, of the termination of the ileum and of the intestines ceco and ascending colon. Then, whe took some measurements of the ileum inside the large intestine. The results were analyzed by Wilcoxon Test (± < 0,05). The terminal ileum showed cylindrical morphology in 100% of the cases. In all of the cases, we observed that the ileal eminence was papilar shape ileal papilla (papilla ilealis) towards the large intestine with an oblique direction. On the top of the papilla we observed one central ostium (ostium ileale), relatively closed and star shaped (75% of the cases), or relatively opened and oval shaped (25%). Our findings demonstrate that the different morphology of the ileo-ceco-colic junction as compared to other animals, another indication against the generalization of the description of this region in mammals.Downloads
