Abstract: Objective To investigate the value of multi-slice spiral CT(MSCT)in diagnosis of the causes of intestinal obstruction.Methods 49 cases of intestinal obstruction confirmed by surgery or clinical diagnosis underwent abdominal MSCT plain and enhanced scanning,three-dimensional post-processing reconstruction was done in 5 cases.CT features were analysed blindly by two senior radiologists,including the thickness,density and degree of enhancement of intestinal walls at the "transition zone" area of intestine and surrounding mesenteric structure.The causes of intestinal obstruction were analysed in combination with clinical history of the patients.Results The causes of intestinal obstruction were suggested by MSCT in 46 cases(94%),including intestinal adhesion in 13 cases,tumor in 11,hernia in 4,ischemic bowel disease in 4,gallstone in 2,gastrolith in 2,Bezoar in 4.paralytic ileus in 3 and appendiceal abscess in 3.Three cases were misdiagnosed.Conclusion MSCT is of significant clinical value in diagnosis of intestinal obstruction,which should be used as the first means in clinic practice.
