Aims To assess patient factors associated with pedunculated (Ip + Isp) and non-pedunculated
(Is + flat) 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 6,445 procedures, 2,621 reported a polyp in at least one colon segment (40.7%).
Pedunculated lesions were reported in 601 procedures and non-pedunculated lesions
in 2,255 procedures.
Reporting of pedunculated lesions varied with age (increasing with increasing age
group, p < 0.0001 overall). Non-pedunculated lesions varied by age with a peak in
the 60–69 age group (p < 0.0001 overall): 10–29 3.0%, 30–39 16.0%, 40–49 23.8%, 50–59
31.9%, 60–69 42.5%, 70–79 42.1%, 80 or over 38.0%.
Reporting of pedunculated lesions varied by BMI (increasing with increasing BMI group,
p = 0.042 overall). Non-pedunculated lesions also varied by BMI, generally increasing
with increasing BMI group (p < 0.0001 overall).
In those who had received a previous total colonoscopy within the last 5 years, reporting
of pedunculated lesions decreased (7.9% vs 10.2%, p = 0.003), while reporting of non-pedunculated
lesions increased (43.2% vs 29.6%, p < 0.0001).
There was no difference in the reporting of either pedunculated (p = 0.121) or non-pedunculated
(p = 0.509) lesions between in- and outpatients. Interestingly, the adequacy of bowel
clearance also had no association with the reporting of either type of lesion (p = 0.935
and p = 0.714).
Conclusions Pedunculated lesions are less commonly reported than non-pedunculated lesions. Reporting
of both pedunculated and non-pedunculated lesions varied by age and BMI. In patients
with a previous total colonoscopy in the past 5 years the reporting of pedunculated
lesions was decreased while reporting of non-pedunculated lesions was increased.
