[Diagnostic value of spiral computed tomography in adhesive ileus].
OBJECTIVE
To discuss the diagnostic value of spiral computed tomography (CT) in adhesive ileus.


METHODS
We retrospectively analyzed 40 patients with adhesive ileus who were diagnosed by CT and confirmed by operations. The main reconstruction method included multi-planar reconstruction (MPR) and sliding thin slab-maximum intensity projection (STS-MIP).


RESULTS
Among all the 40 patients, localization diagnosis was correct in 32 patients (80%) and partially correct in 8 patients (20%). The main signs included: (1) dilated proximal intestinal canal and collapsed distal intestinal canal in 40 patients (100%); (2) smooth transitional zone in 39 patients (97.5%); (3) delayed enhancement of regional bowel in 33 patients (82.5%); (4) beak sign in 32 patients (80%); (5) adhesions balteum in 6 patients (15%); and (6) pseudotumor appearance in one patient (2.5%).


CONCLUSIONS
Spiral CT has an important value in detecting adhesive ileus.
