    Abstract:
    BACKGROUND: Open access endoscopy allows reference of patients for endoscopic procedures without prior gastrointestinal consultation, allowing the procedure to be more accessible. This practice is becoming increasingly widespread in the United States and other countries and has become commonplace in clinical practice in Israel. The objective of our study is to bring forward our experience with an open access referral system for colonoscopy and to measure the yield and safety of colonoscopy in this system. METHODS: Between January 2001 and September 2003, 10,866 colonoscopies were performed. Patient's charts were reviewed for the following data: demographics, indication for endoscopy, endoscopic and histopathologic findings, and complications. The practice guidelines of the American Society for Gastrointestinal Endoscopy were used to assess appropriateness of colonoscopy. RESULTS: 3533 pathologic findings were found, in 2978 colonoscopies. 2336 polyps were removed, including 18% hyperplastic, 26% tubular adenomata, 13% villous adenomata, 11% tubulovillous adenomata. Advanced disease was found in 41% of pathologic findings, 11% were invasive cancer. Rate of colonoscopies "generally indicated" according to American Society for Gastrointestinal Endoscopy guidelines was 78% with a rate of colonoscopies "generally not indicated" of 22%. Colonoscopy was completed successfully to the cecum in 93% of patients. 0.08% had serious complications during or immediately after colonoscopy. CONCLUSIONS: Our results suggest that open access colonoscopy is a reliable and safe method for screening average risk population. As colonoscopy is becoming the recommended screening model for colorectal cancer this attitude of performing screening in an open access system could both cut costs in the future and improve availability, in an aim to become common practice.
