[A rare cause of intestinal obstruction].

Three-hundred-thirteen cases of small and large bowel obstructions surgically managed, from May 1974 to September 1995, are reviewed. Particularly, 10 uncommon cases are described: 3 hernias in anomalous recesses, 1 small bowel spontaneous hematoma, 2 Ogilvie syndromes, 1 obstruction due to cholecystitis, 1 left diaphragmatic hernia, 1 encapsulating peritonitis, 1 incarcerated Spigelian hernia. Their aetiopathogenetic and clinical patterns are examined. The Authors conclude, in agreement with Literature, that small bowel obstructions need urgent operation because of high risk of ischemic lesions. In large bowel obstructions operation is suggested after more careful diagnostic researches and adequate patient preparation. In some uncommon obstructions the purpose is to restore normal anatomical conditions.
