Rescreening colonoscopy practice after a negative index colonoscopy in a clinical setting; cross-sectional study for interval and outcomes of rescreening colonoscopy.

Abstract

BACKGROUND/AIMS:

We evaluated the rescreening colonoscopy practice after negative index colonoscopy (IC) in a real clinical setting.

METHODOLOGY:

We reviewed the individual records of aged over 40 who had negative IC at a single center between 2003 and 2005. The quality of the IC including bowel preparation (using Boston bowel preparation scale, BBPS), cecal intubation, withdrawal time and the incidence and risk factors for advanced lesions during the rescreening colonoscopy were analyzed.

RESULTS:

On 1570 negative ICs, 32.6% (n = 512) had rescreen ing colonoscopy until August, 2011. The rescreened group showed significantly lower quality of the IC compared to the group not rescreened (mean BBPS 7.9 vs. 8.2, p = 0.032, mean withdrawal time 5.2 vs. 5.7 minutes, p = 0.003). Rescreening detected polyps in 33.4% (n = 171) and advanced lesions in 3.7% (n = 19, 73.7% male; p = 0.022) including cancers (0.4%, n = 2). Male gender (odds ratio, 2.995; 95% confidence interval, 1.199-7.481) was an independent risk factors for advanced lesions on rescreening.

CONCLUSIONS:

Advanced lesions were detected in 3.7% of rescreening group after negative IC and male was a risk factor. Following a low-quality IC, a rescreening colonoscopy was performed with short interval in a clinical practice.
