Aims To assess the patient factors associated with flat and protruded lesion reporting,
as defined by Paris classification.
Methods The development of the procedure questionnaire, by the European Colonoscopy Quality
Investigation (ECQI) Group, has been previously described (UEGW 2015 and 2016). We
analysed data collected between 2/6/16 and 30/4/18.
Results Of 6445 procedures, 2621 reported a polyp in at least one segment (40.7%). Protruded
lesions were reported in 2160 procedures and flat lesions were reported in 692 procedures.
Reporting of both flat and protruded lesions varied by age (generally increasing with
increasing age, p < 0.0001). Reporting also increased for both flat and protruded
lesions in those who had received a previous total colonoscopy within the last 5 years
(p < 0.0001): flat lesions 13.8% vs 9.8%; protruded lesions 38.7% vs 29.2%. Flat lesion
reporting was not associated with BMI (p = 0.667), while protruded lesion reporting
was generally higher in higher BMI groups (p < 0.0001).
Flat lesions were more commonly reported in inpatients than outpatients (16.2% vs
10.7%, p < 0.0001), while protruded lesions were more common in outpatients (29% vs
33.4%, p = 0.023).
The reporting of flat lesions was significantly higher in procedures reporting adequate
bowel clearance (11.4% vs 8.0%, p = 0.004); no change in protruded lesion reporting
(p = 0.317).
Conclusions Higher BMI was associated with increased reporting of protruded lesions, but had
no effect on flat lesion reporting. Flat lesions were more likely to be reported in
inpatients while protruded lesions were more likely in outpatients. Protruded lesion
reporting was unaffected by adequacy of bowel clearance while flat lesion reporting
was higher in procedures reporting adequate bowel clearance.
