[Non-neoplastic pathology of the last ileal ansa (anatomo-surgical problems)]

The surgery of the last ileal ansa in case of non-neoplastic pathology bears some problems of technical nature, bound to the remarkable anatomic variabilities in the arterial blood supply to terminal ileum. The authors report the observation of three cases of non-neoplastic pathology of the last ileal ansa, treated with different technique in relation to the type of arterial blood supply remarked. In a case an ileum resection with termino-terminal anastomosis was performed, and in the other two cases a resection of the last ileal ansa, followed by an ileo-caecal reimplantation, was effected.
