Abstract：ObjectiveTo analyze the clinical characteristics of primary small intestinal tumor and to explore the diagnosis and treatment. MethodsA retrospective analysis was conducted on clinical characteristics, pathological types, and diagnosis and treatment methods of 80 cases of primary small intestinal tumor in our hospital from 2007 to 2014.ResultsAmong the 80 cases, the main clinical manifestations were abdominal pain, gastrointestinal bleeding, anemia, intestinal obstruction, abdominal mass and marasmus. Among them, 30 cases of malignant tumors were mainly adenocarcinoma, malignant stromal tumor, lymphoma and signet-ring cell carcinoma, while 50 cases of benign tumors were benign stromal tumor, hamartoma, adenoma, hemangioma and lipoma. Primary small intestinal tumors mainly developed in jejunum, followed byduodenum, ileum, and the junction of the duodenum and jejunum. Balloon-assisted enteroscopy (BAE) was significantly higher than capsule endoscopy, abdominal computed tomography (CT) and gastrointestinal barium radiography in positive detection rate of small intestinal tumor (97.5%, 88.2%, 68.8% and 66.7% respectively,P<0.01).ConclusionThere is no specificity in clinical manifestations of primary small intestinal tumor. BAE has an important clinical value in the diagnosis and treatment of small intestinal tumor. Combination of BAE, capsule endoscopy, abdominal CT and gastrointestinal barium radiography can obviously improve the diagnosis rate of small intestinal tumor.
