Colonoscopy plays a critical role in colorectal cancer (CRC) screening and has been widely regarded as the gold standard. Cecal intubation rate (CIR) is one of the well-defined quality indicators used to assess colonoscopy.

To assess the impact of new technologies on the quality of colonoscopy by assessing completion rates.

Material and methods
This was a dual-center study at the 2nd Department of Surgery at Jagiellonian University Medical College and at the Specialist Center “Medicina” in Krakow, Poland. The CIR and cecal intubation time (CIT) in three different eras of technological advancement were determined. The study enrolled 27 463 patients who underwent colonoscopy as part of a national CRC screening program. The patients were divided into three groups: group I – 3408 patients examined between 2000 and 2003 (optical endoscopes); group II – 10 405 patients examined between 2004 and 2008 (standard electronic endoscopes); and group III – 13 650 patients examined between 2009 and 2014 (modern endoscopes).

There were statistically significant differences in the CIR between successive eras. The CIR in group I (2000–2003) was 69.75%, in group II (2004–2008) was 92.32%, and in group III (2009–2014) was 95.17%. The mean CIT was significantly reduced in group III.

Our study shows that the technological innovation of novel endoscopy devices has a great influence on the effectiveness of the CRC screening program. The new era of endoscopic technological development has the potential to reduce examination-related patient discomfort, obviate the need for sedation and increase diagnostic yields.
