Objective: Malignant tumors of the small intestine are uncommon. There are few reports of clinical reviews, therefore, we analyzed the data of cases of small intestinal malignant tumors operated at our hospital.
Methods: We conducted a retrospective analysis of zed the clinical and pathological characteristics of cases of small intestinal malignant tumors operated at our institution from June 2007 to October 2016.
Results: There were 26 cases. The mean age was 66.0 ± 14.0 years and 16 of the patients were female. Of the 26 cases, 25 had symptoms, as follows: abdominal pain in 14 cases, vomiting in 5 cases, palpable abdominal tumor in 3 cases, lower blood in 2 cases, and anemia in 1 case. Preoperative diagnosis could be established in 9 cases. The tumor was located in the jejunum in 14 cases, in the ileum in 9 cases, and the tumor location was unknown in 3 cases. Histologically, 9 cases were diagnosed as gastrointestinal stromal tumor (GIST), 6 as malignant lymphoma, 6 as metastatic small intestinal tumor, and 5 as small intestinal cancer.
Conclusion: Small intestinal malignant tumor may cause intestinal obstruction or perforated peritonitis, carry a poor prognosis and should be included in the differential diagnosis of such condition.
