  • Title: The role of contrast radiography in presumed bowel obstruction.
    Author: Riveron FA, Obeid FN, Horst HM, Sorensen VJ, Bivins BA.
    Journal: Surgery; 1989 Sep; 106(3):496-501. PubMed ID: 2772824.
    Abstract:
    A retrospective review of 229 patients with a final diagnosis of small-bowel obstruction was undertaken to evaluate the role of contrast radiography in the management of their conditions. In 84 patients (37%) the clinical findings and plain abdominal roentgenograms were sufficient for diagnosis and subsequent management. Of the remaining 145 patients with equivocal findings, 27% had an upper gastrointestinal series, 29% a barium enema, and 44% had both. Useful information (complete obstruction, unobstructed passage of contrast, or diagnosis other than adhesional obstruction) was obtained from 86% of the radiographic studies. Three patients had negative contrast studies yet eventually underwent adhesiolysis (enterolysis) and were classified as false-negative. Two patients had evidence of high-grade obstruction yet had nonoperative resolution and were classified as false-positive. The mortality in the contrast group (7%) was not statistically different than that in the no-contrast group (7%). Contrast radiography is a safe and effective means of increasing diagnostic accuracy in patients with presumed small-bowel obstruction.
