Abstract：Objective To evaluate the diagnostic value of multislice spiral computed tomography （MSCT） in small bowel diverticulum and to analyze the common misdiagnosis reasons of small bowel diverticulum.Methods From January 2015 to December 2017,30 patients from outpatient clinics and hospitalization diagnosed as small intestine diverticulum by plain and enhanced CT scans on upper abdomen and 25 patients who were initially diagnosed as non-small bowel diverticulum but eventually proved were enrolled in our hospital in order to analyze the MSCT performance and the misdiagnosis reasons of these patients.Results The final definite diagnosis of small bowel diverticulum was in 55 patients mostly presenting with protrusion to the enteric cavity and gas or gas-liquid mixed density.The simple manifestation was less liquid density shadow.The diverticulum frequently located at the descending segment and the junction between the descending segment and the horizontal segment of duodenum,with little chance to be in horizontal segment.The small intestine diverticulum was mostly complicated with gastrointestinal diseases such as gallbladder stones and esophageal hiatal hernia,etc.The small intestine diverticulum in clinical practice was more likely to be misdiagnosed as intestinal obstruction,intestinal hemorrhage and perforation,inguinal hernia,appendicitis,which were mainly associated with single clinical manifestation and anatomic site of the small intestine diverticulum.Conclusion MSCT has a high value for the diagnosis of small bowel diverticulum,but it is easy to diagnose small bowel diverticulum as other diseases in the clinic.Therefore,attention should be paid to differential diagnosis.
