[1-3]. However, in recent years because of improved diagnostic accuracy, the incidence of small bowel cancer is rising. It is estimated that 10, 470 new cases of primary SI cancer will be diagnosed in the US with 1450 cancer-related deaths . The most frequent histologic types of small bowel malignant tumors include adenocarcinomas, carcinoids, lymphomas, and sarcomas.
