Aims Faecal immunochemical test (FIT) is used for colorectal cancer screening. The aim of this study is describe findings in the distal and proximal colon in a FIT colorectal screening programme and its relationship with FIT value.

Methods Multicenter Prospective study of 692 patients referred from the colorectal screening program with a positive FIT (October 2016 and October 2018).

Results 692 patients were included between 50 and 69 years old, 44 were excluded due to inadequate preparation and/or incomplete colonoscopy. 55.2% are males. Total ADR is 61.1%. The adenoma detection rate in right colon is 36% and in distal colon is 61%. The highest FIT values ​​correlate with larger polyps in the sigma and rectum colon (p: 0.022 and p: 0.007), however there are no differences in the number of polyps per section and the FIT values. CRC is diagnosed at 3.46% of the 692 patients included; being located in the distal colon in 70% of cases.

Conclusions In colo-rectal screening programme with positive FIT: 1) Adenoma detection rate is higher in distal colon. 2) Advanced adenomatous lesions and CRC are most often found in the left colon. 3) It is observed that when FIT values are higher, polyp`s size tend to have higher size in the left size of the colon and rectum sections.
