[Small bowel tumors -- peculiarities of diagnosis and evolution]

The authors analyze 13 cases of small bowel tumors. There are emphasized the difficulties of diagnosis, which is rarely established before the laparotomy. In the same time, clinical features are few and operations are often performed too late, in emergency, due to tumors complications (perforation, bleeding, occlusion). There are also presented new etiopathogenic hypothesis, recently mentioned in literature. Surgical treatment is followed by many post-operative complications. Five-years survival is low, under 40% of patients.
