Abstract

Objective The characteristics and clinical significance of multi-slice spiral CT of elderly patients with small bowel tumors complicated with intussusception before and after surgery. Methods 28 elderly patients with small bowel tumors complicated with intussusception who were treated in our hospital between October 2013 and October 2014 were selected as the study object. 16 slice spiral CT scan was adopted before surgery to perform plain scan and enhanced scan. The image features of lesions in arterial and venous phase were analyzed. The postoperative and follow-up CT findings of the patients were observed. Results The accuracy rate of preoperative CT in the diagnosis of 28 patients with small bowel tumors complicated with intussusception was 89.29% (25/28). There were 5 patients misdiagnosed, including 2 patients with extensive necrosis in small intestine and ascending colon and 3 patients with intraperitoneal hernias. There were 7 patients with small intestine intussusception, 11 patients with colonic intussusception, 10 patients with ileocecus intussusception. Before suegry, 24 patients were diagnosed by CT as small bowel stromal tumors and hamartomas. Plain scan showed equal-density masses. After enhancement, they were significantly enhanced and the degree of enhancement was similar to that in arterial phase. Conclusion Multi slice spiral CT can accurately reflect the characteristics of elderly patients with small bowel tumors complicated with intussusception before and after surgery. It is of important guiding significance in selection of the surgical modes and evaluation of prognosis. It worthy of clinical promotion and application.
