Perception errors with double-contrast enema after a positive guaiac test.

J Kewenter, J Jensen, M Boijsen

    Gastrointestinal Radiology
    |January 1, 1987
    PubMed
    Summary

    Double-contrast enema (DCE) missed several colorectal neoplasms, even with multiple radiologists. Combining DCE with rectosigmoidoscopy is crucial for accurate colorectal cancer detection.

    Area of Science:

    • Gastroenterology
    • Radiology
    • Oncology

    Background:

    • Colorectal cancer screening relies on imaging techniques like double-contrast enema (DCE).
    • Accurate detection of colorectal neoplasms is critical for early intervention and improved patient outcomes.
    • Perception errors in radiology can lead to missed diagnoses of significant pathologies.

    Purpose of the Study:

    • To evaluate the effectiveness of double-contrast enema (DCE) in detecting colorectal neoplasms.
    • To assess the impact of multiple radiologists' interpretations on DCE accuracy.
    • To determine the added value of rectosigmoidoscopy as a complementary diagnostic tool for colorectal neoplasms.

    Main Methods:

    • Retrospective analysis of 117 individuals with positive guaiac tests.
    • Review of double-contrast enema (DCE) radiographs by 4 experienced radiologists.
    • Comparison of DCE findings with rectosigmoidoscopy results.

    Main Results:

    • Radiologists overlooked 3-6 out of 12 colorectal neoplasms larger than 1 cm per individual.
    • Even with combined readings from 2-4 radiologists, 2 small carcinomas were missed due to perception errors.
    • Rectosigmoidoscopy identified one of the missed small carcinomas, highlighting its complementary role.

    Conclusions:

    • Double-contrast enema (DCE) alone has limitations in detecting all colorectal neoplasms, including small carcinomas.
    • Combining DCE with rectosigmoidoscopy is essential to minimize the risk of missing colorectal neoplasms.
    • While combining radiologists' readings can improve detection, it may increase false-positive findings.
