  1. Physicians'perceptions of dysplasia and approaches to surveillance colonoscopy in ulcerative colitis.

    Article - En anglais


    Colonoscopic biopsy surveillance to detect dysplasia, defined as a neoplastic change of the epithelium without invasion into the lamina propria, in patients with ulcerative colitis has become a widespread practice.

    We undertook a survey study to determine physicians'perceptions of, and approaches to, dysplasia surveillance colonoscopy in ulcerative colitis.


    Members of two regional gastroenterology associations in the United States, including both academic and private practice-based gastroenterologists, and a group of senior gastroenterology trainees were surveyed by means of a written questionnaire.

    The questionnaires were distributed at three separate meetings of practicing gastroenterologists or trainees :

    • 1) a Gastrointestinal pathology course for second-year gastroenterology fellows from training programs around the United States (February 1993,

    • Los Angeles,

    • CA) ; 2) a meeting of the Southern California Gastroenterology Society (March 1993, Los Angeles, CA) ; and 3) a meeting of the Pacific Northwest Gastroenterology Society (June 1993, Seattle, Washington).

    The percentages of all responses were tallied and analyzed for the group as a whole as well as by subgroup analysis.

    Understanding of the definition of dysplasia and specific practice techniques and approaches were the main outcomes sought.


    Only 19% of respondents correctly identified the definition of dysplasia.
