The diagnosis value of intestinal obstruction by Multislice computed tomography / 中国基层医药

ABSTRACT

Objective To evaluate the role of Muhislice computed tomography(MSCT) in the diagnosis of acute ileus.Methods 50,cases with suspected of intestinal obstruction were scanned using MSCT.The diagnostic resuits of MSCT were compared with operation and pathology.Results The existence of ileus was diagnosed in 96% (48 of 50 cases) on MSCT scans,the sensitivity was 95% (41 of 43 cases),the specificity was 92% (46 of 50 cases).The accurate rate of X-Ray plain film in the diagnosis of ileus in this study was 66% (33 of 50 cases),the sensitivity was 76% (33 of 43 cages),the specificity was 68% (34 of 50 cases).The accuracy of etiological diagnosis of ileas made by MSCT in 17 cases proved by operation or clinical follow-up was 82% (14 of 17 cases),and the accuracy of location was 88% (15 of 17cases).The rate of diagnosis accord of CT and surgery in intestinal were no significant differenco(X~2=2.78,P＞0.05);The rate of in line with diagnosis of CT and surgery in intestinal were no significant difference;The rate of in line with diagnosis of CT and surgery in colon were significant(X~2=23.95,P＜0.05).Conclusion Intestinal obstruction is more clearly revealed by MPR of MSCT,which improves the diagnostic ability of acute intestinal obstruction.
