[Non-neoplastic intestinal occlusion]

In the last ten years etiology's frequency of non-neoblastic bowel occlusions has changed. Headway against occlusions percentage decreasing due to post-operative stenosis, hernial strangulation, adhesional bridles, etc., mechanical ileus observations increase in percentage round about 20%, as colon acquired diverticulitis complications. This is essentially due to the mean survival increasing in the whole occidental world and, particularly, in Italy. Therefore, we have to expect an increase of this kind of occlusion that presents, for his characteristics, a moderate diagnostic etiological pre- and intra-operative difficulty. This diagnostic doubt can afford a destroyer intervention, with a useless lymphadenectomy, more than needful with morbidity and mortality increasing.
