Background. Recent reports have confirmed the improving trends in colorectal cancer (CRC) incidence and outcomes. Still, disparities in incidence and mortality in CRC continue to persist between major ethnic groups despite the provision of widespread screening and improved care. We aimed to outline, from an endoscopic point of view, ethnic disparities in major endoscopic measures concerned with CRC screening and detection and track their impact on patients' outcomes. Methods. We reviewed electronic reports of patients referred for colonoscopy procedures over 20 years. We compared demographic, clinical, and endoscopic findings between major ethnic population groups in Israel. In addition, trends of screening utilization, bowel preparation, and polyp detection rates were tracked, and the incidence of CRC diagnosis was followed. Results. A total of 51307 patients had undergone colonoscopies, of whom 16% were Arabs, and 84% were Jewish. The procedures performed for CRC screening throughout the study period were significantly lower in Arabs (5% vs. 13.1%; P < 0.0001). In parallel, for most of the follow-up period, the Arab patients had higher rates of inadequate bowel preparation (overall: 19.9% vs. 12%; P < 0.001) and a lower polyp detection rate (16.7% vs. 22.5%; P < 0.0001). Expectedly, the incidence of CRC has steadily decreased in the Jewish group, while an adverse pattern of increasing incidence was documented in the Arab patient during the follow-up period. Conclusion. Characterized by lower screening utilization and poor bowel preparation, the incidence of CRC development in Arab patients is increasing, while improving trends of CRC were observed in their Jewish counterparts.
