[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%).
Conclusion: Spiral CT has an important value in detecting adhesive ileus.
