Abstract：Objective To comparatively analyze the effectiveness of MSCT (Multi-Slice Spiral Computerized Tomography), erect abdominal plain films and upper gastrointestinal imaging in diagnosis of gallstone ileus. Methods Retrospective analysis of 10 patients with confirmed gallstone ileus from 2011 to 2013 were made. Of the 10 cases, all underwent abdominal MSCT and erect abdominal plain films; 7 were examined with upper gastrointestinal imaging. Radiological findings of the allotriolith, intestinal obstruction, pneumatosis in the gallbladder and biliary tract as well as cholecysto-intestinal fistulas obtained by three imaging techniques were comparatively analyzed. Results The detection rates of the allotriolith, intestinal obstruction, pneumatosis in the gallbladder and biliary tract revealed by MSCT were 100%, 90%, 90% respectively versus 20%, 90%, 10% by erect abdominal plain films and 28.6% (2/7), 100% (7/7), 0 by upper gastrointestinal imaging. MSCT (50%) was inferior to the upper gastrointestinal imaging [100% (7/7)] in display of cholecysto-intestinal fistulas. Conclusion In comparison with other two imaging techniques, MSCT showed the greatest effectiveness in diagnosis of the gallstone ileus; the upper gastrointestinal imaging was of comparatively highest significance for detection of cholecysto-intestinal fistulas (Fistulas of Stomach and Duodenum); the erect abdominal plain film was proven to be an imaging technique with the least effectiveness.
