Figure 1 Healthy small bowel. A: the Patent Blue injected into the subserosal layer outlines a lymphatic vessel which rectilinearly goes into the mesenterium towards the lymph-node (arrow). Lymphatic vessels longitudinally directed are not observed; B: Small bowel affected by Crohn’s disease: the Patent Blue injected at the level of a skip lesion outlines a lymphatic vessel longitudinally directed in the small bowel wall and only from this site can it spread into the mesenterium.
