Introduction:
Colorectal cancer is one of the most sprayed cancers; the gold standard of diagnostic is a colonoscopy. The quality of this examination is depended on many factors, which includes doctors' experience.
Purpose:
The purpose of this study is to establish the main factors affecting the completeness of colonoscopy in colorectal cancer screening.
Materials And Methods:
Endoscopists were questioned; descriptive statistics methods and logistic regression were used.
Results And Discussion:
The main factors that influence the quality of screening colonoscopy were identified: experience in colonoscopy, theoretical training, participation in the screening program, and number of annual colonoscopies. The calculated odds ratio for the selected dependent variable is calculated.
Conclusions:
The experience for more than 5 years (p = 0.017) and at least 200 colonoscopies per year (p = 0.004) are the main factors that allow to perform complete colonoscopy in 90% or more of cases.
