[Quality in Colonoscopy: Experience in an Endoscopy Center in Boyacá, Colombia]

Colorectal cancer ranks the third place in incidence in Colombia by 2020. Screening programs, such as colonoscopy, help to reduce deaths related to colorectal cancer deaths by 18 to 26%. Quality indices can be classified intopre-procedure, trans-procedure and post-procedure. For this reason, all endoscopist and institutions should have quality indicators.

To evaluate the quality of colonoscopy and its predictors in an outpatient endoscopy center.

A cross-sectional study in patients over 18 years of age undergoing colonoscopy between February 2017 to March 2022 in a specialized endoscopy center based in Boyacá, Colombia, using a real-time instrument. The polyp detection rate and predictors of colonoscopy quality were determined.

9760 records were collected, the rate of cecal intubation was 94.6%, while the detection rate of polyps was 17.1%. The time of removal of the endoscope (OR: 2.35; 95% CI: 1.92-2.88 p = 0.001), a Boston rating greater than 6 (OR 1.4 95% CI 1.1- 1.7 p < 0.005), sex (OR: 1.42; 95% CI: 1.27-1.59; p = 0.001) and age (OR: 2.24; 95% CI: 1.91-2.4; p = 0.001) were predictors for polyp detection. A Boston rating greater than 6 (OR: 37.8; 95% CI: 29.7-48; p < 0.05), sedation (OR: 7.87; 95% CI: 3.07-20.01; p < 0.05) and age (OR: 1.31; 95% CI: 1.031.67; p = 0.026) were predictors for cecal arrival.

Predictors of good quality colonoscopy are good preparation, male sex, age under 60 years and use of sedation.
