[Adenocarcinoma of the small intestine including the duodenum]

Adenocarcinoma, malignant lymphoma and leiomyosarcoma are the main malignant tumors found most frequently in the small intestine and adenocarcinoma should be differentiated from these lesions as well as benign tumors. Ten cases with primary adenocarcinoma of the duodenum and 14 of the small intestine (the jejunum and ileum) were diagnosed and treated surgically in our clinic during recent 22 years. Analysing the clinical signs, symptoms and roentgenological features of these patients, the diagnosis, treatment and prognosis for these lesions were discussed and reviewed. To enhance the 5-year survival rate for these patients, the early diagnosis in the curative stage should be established.
