title: [A Korean national survey for colorectal cancer screening and polyp diagnosis methods using web-based survey].
abstract: OBJECTIVE
  There is a paucity of national guideline for colorectal cancer screening and polyp diagnosis in Korea. Thus, we investigated the present state of colorectal cancer screening and polyp diagnosis methods using web-based survey to use as reference data for developing a guideline.
  
  
  METHODS
  A multiple choice questionnaires of screening recommendations was sent via e-mail to members of the Korean Association for the Study of Intestinal Diseases and primary care physicians who participated in the national colonoscopy surveillance program. Among 425 colonoscopists, a total 263 colonoscopists replied (response rate, 61.9%).
  
  
  RESULTS
  The most commonly recommended starting age for colorectal cancer screening and polyp diagnosis was 50 years old in the average risk group, and 40 years old in groups who had a family history of colon cancer (64.3% and 65.0% respectively). Surgeons had a tendency to recommend screening in younger people than internist do. Ninety-eight percent of physicians recommended screening colonoscopy to asymptomatic, average-risk patients as a first choice. Only 2% of physicians chose sigmoidoscopy as a screening tool. When the initial colonoscopy showed a negative finding, over 60% of internists repeated the exam 5 years later, whereas 62% of surgeons did so within 3 years.
  
  
  CONCLUSIONS
  The starting age of colorectal cancer screening and the interval of the colorectal polyp examination are not uniform in various medical environments, and there is a discrepancy between the practical recommendations and western guidelines. Thus, a new evidence-based national practice guideline for colorectal cancer screening and polyp diagnosis should be developed.
