  • Title: The sensitivity of radiography of the postoperative stomach.
    Author: Ott DJ, Munitz HA, Gelfand DW, Lane TG, Wu WC.
    Journal: Radiology; 1982 Sep; 144(4):741-3. PubMed ID: 7111718.
    Abstract:
    The results of radiology and endoscopy were compared in 140 patients who had undergone gastric surgery for ulcer disease. Of 74 patients who were examined with single-contrast radiography, 37 had abnormalities that were demonstrated endoscopically. The radiographic sensitivities in these patients were: gastritis 2/22 (9%); ulcer 3/5 (60%); obstruction 8/8 (100%); and miscellaneous abnormalities 2/2 (100%). The predictive accuracy of a diagnosis of ulcer was 38%. Of the 66 patients who were examined with double-contrast radiography, 33 abnormalities were found with endoscopy. The radiographic sensitivities were: gastritis 3/13 (23%); ulcer 7/10 (70%); obstruction 4/4 (100%); and miscellaneous abnormalities 6/6 (100%). The predictive accuracy of a diagnosis of ulcer was 44%. Radiology appears to be unreliable in diagnosing gastritis and recurrent ulceration in the postoperative stomach. The double-contrast technique does not offer significant improvement over the single-contrast method in evaluating these postoperative problems.
