Background: Colonoscopy is the gold standard procedure for screening for colorectal cancer and surveillance after polypectomy or colorectal cancer surgery for diagnosis in symptomatic patients and patients with fecal occult blood; and for screening in the high risk population. The adherence of referring physicians to the accepted recommendations can prevent long waiting lists for colonoscopy and save lives, costs and resources. Objectives: To evaluate the knowledge of primary care physicians and gastroenterologists in Israel about current guidelines for colonoscopy screening and surveillance. Methods: A 10-item questionnaire on proper follow-up colonoscopy for surveillance after polypectomy and screening for colorectal cancer in various clinical and epidemiological situations was administered to 100 expert gastroenterologists and 100 primary care physicians at a professional meeting. Answers were evaluated for each group of physicians and compared using the chi-square test. Results: The compliance rate was 45% for the gastroenterologists and 80% for the primary care physicians. The rate of correct answers to the specific items ranged from 18.7% to 93.75% for the gastroenterologists and from 6.2% to 58.5% for the primary care physicians (P < 0.001 for almost every item). Conclusions: The knowledge of physicians regarding the screening and surveillance of colorectal cancer needs to be improved.
