Abstract: Due to the high incidence of small bowel obstruction, early accurate diagnosis and comprehensive evaluations are very important for choice of the treatment methods. Multi-slice spiral computed tomography(MSCT) has very high accuracy in the evaluation of whether there is any obstruction; obstructive sites, severity degrees and causes, and can also provide useful information for secondary intestinal ischemia. The present research situations of MSCT in evaluation of the small bowel obstruction were reviewed in this article.
