Diagnosis and treatment of primary malignant tumors of the small bowel]

To study the clinical characteristics, effective diagnostic methods and therapeutic measures of primary malignant tumors of the small bowel so as to improve therapeutic effect.In this paper 75 cases of primary malignant tumors of the small bowel were analyzed. Survival rates were calculated with Life Table, and computer Cox multivariate analysis model was used for survival analysis.The most frequent clinical manifestations of primary malignant tumors of the small bowel were abdominal pain, abdominal mass, emaciation and intestinal obstruction. Gastrointestinal barium meal roentgenography was performed in 13 cases, with an accurate diagnostic rate of 84.6%. The 1-,3- and 5-year survival rate after radical resection was 87.5%, 68.7% and 48.1%, respectively, while that for palliative resection was 57.9%, 33.8% and 24.1%, respectively. The factors including age, histological type, tumor site and type of resection were selected into Cox model in survival analysis.For primary malignant tumors of the small bowel, gastrointestinal barium meal roentgenography is the most valuable method for diagnosis, and surgical radical resection is the most effective therapy. The significant prognostic factors are age, histological type, tumor site and type of resection. Chemotherapy had no effect on prognosis.
