Objective To investigate the CT features and different risk CT findings of intestinal stromal tumor. Methods The CT imaging data of 25 cases of intestinal stromal tumor confirmed by pathology and compared with operative and pathologic findings were retrospectively studied. Analyzing the CT features based on Histopathologieal classification of the different risk groups and using chi-square test to compare the differences. Results There were 9 cases which tumors originated from the jejunum, and 13 cases from ileum, only 3 cases from duodenum. Among them, 2 cases were submucosal type, 13 cases were intramural type, and 10 cases were subserous type. The pathologic patterns of different risk which included high-risk, intermediated-risk, low-risk, and very low-risk were 12 cases, 7 cases, 5 cases and 1 cases respectively. A typical CT manifestations of intestinal stromal tumors were a outward growth of irregular or round soft tissue mass originated in small intestine which had clear boundary and the non-homogeneous density, which corresponding to necrosis, cystic change, mucoid degeneration and sinus or cavity. Mesenteric fat invaded by tumor showed high-density lines or points shape. The Enhancement of lesion was obvious and not homogeneous which showed little change in peak of enhancement between arterial phase and venous phase. Intestinal stromal tumors took 5 cm as the boundary which including different size, shape, density, and appearance vessel-like artery shadow at arterial phase between different risk groups(low, very low-risk group and intermediated, high-risk group) were statistically different (P <0.05), while enhanced degree without significant difference (P > 0.05). Conclusion CT findings of small intestine stromal tumor have characteristics and CT features have significant difference between different risk groups. These features of more than 5 cm in diameter, non-homogeneous density, irregular shape and chaos appearance like vascular enhancement are showed in intermediated-high-risk group.

Objective To study the clinicopathologic characteristics and the prognostic factors of gastric stump cancer (GSC). Methods A total of forty-seven patients with GSC from Jan 2000 to Dec 2006 were enrolled in this study for retrospective analysis. Initial surgery was performed for gastric benign disease in 39 patients and for malignant disease in 8 patients, which were divided into 2 groups for analysis. The prognosis of all 47 patients were analyzed. Results The mean interval between previous gastrectomy and diagnosis of GSC was 24.4 years. Tumor developed mostly in the patients with Billroth- Ⅱ reconstruction, and male more than female. Tumor located at anastomotic site mostly, at stump stomach and cardia secondly. The mean interval for patients who had undergone their first gastrectomy for malignant disease was shorter than that with benign disease(P<0.05). Histology, therapy and prognosis showed no significant differences between two groups (P>0.05). Disease TNM stage and total radical gastrectomy were shown to be significant predictor for the outcome of patients with GSC (P <0.01). Conclusion Now the GSC patients with initial surgery performed for malignant disease are increased, which are no siginificant different to patients with benign disease. Early diagnosis and an aggressive surgical approach are crucial to achieve better outcomes for patients with GSC.
