Multidetector Computed Tomography Findings of Adhesive Internal Hernias.

OBJECTIVE

To identify multidetector computed tomography (MDCT) findings of surgically confirmed adhesive internal hernias (IHs).

METHODS

Two gastrointestinal radiologists performed blinded, independent, and retrospective reviews of MDCT findings from a consecutive cohort of 35 adhesive IH and 41 adhesive small-bowel obstruction cases that had undergone surgery within 48 hours after MDCT. Univariate statistical analyses were performed to assess CT signs of adhesive IHs and CT findings of intestinal necrosis in patients presenting with adhesive IHs.

RESULTS

Dislocated cluster of the intestine (P = 0.005), 2 transitional zones (P = 0.002), and presence of fat in the center sign (P = 0.001) were key CT outcomes that were significantly associated with adhesive IHs. Additionally, intramural hemorrhage was found the MDCT feature indicative of intestinal necrosis (P = 0.028).

CONCLUSIONS

This study illustrates specific MDCT findings of IHs, and these observations may help guide early clinical management of the condition.
