| Abstract: | Six cases of perforation of the small intestine, one secondary to anaphylactoid purpura and five spontaneous, are reported. Ingestion of an iced drink acted as a trigger in two cases. A vascular genesis is put forward to explain the aetiopathogenesis of two cases and it is noted that perforation of this type is present in the final ileal ansa, at the mesenterial margin. In three cases, histology revealed the presence of double refraction crystal. These came from vegetal residues and are probably capable of penetrating from the lumen into the mucosa causing a foreign body reaction, abscess and subsequent perforation. In these cases, perforation occurred in an ansa located further away than the last ileal ansa (about 3 m) and on the mesenterial margin. Intestinal resection and subsequent end-to-end, single layer anastomosis were performed in all cases. |
