Abstract:Objective: To study the application value of multi-slice spiral CT in the diagnosis of small intestinal obstruction. Methods: 88 cases of patients with small intestinal obstruction confirmed by surgery in our hospital from January 2012 to December 2016 were selected for the study and treated with multi-slice spiral CT examination. The accuracy rates of the site, degree and etiology of small intestinal obstruction were calculated by the multi-slice spiral CT diagnosis. Results: There were 80 cases of small intestinal obstruction correctly detected by CT with the accuracy rate of 90.9%, including 6 cases of duodenal obstruction, 17 cases of jejunum obstruction and 57 cases of ileal obstruction. There were 60 cases of complete small intestinal obstruction and 21 cases of incomplete small intestinal obstruction correctly detected by CT with the accuracy rate of 92.1%. And there were 79 cases of small intestine obstruction detected with etiology by CT with the accuracy rate of 89.8%, including 39 cases of intestinal adhesions, 14 cases of inflammation, 11 cases of tumors, 5 cases of external hernia, 4 cases of intestinal torsion, 2 cases of traumatic small intestinal obstruction, 2 cases of blood-borne small intestinal obstruction and 2 cases of congenital small intestinal obstruction. Conclusion: Multi-slice spiral CT can accurately diagnose the site, degree, etiology of small intestinal obstruction, and have an important guiding role in surgical treatment.
