Aims To assess the endoscopic interventions performed in procedures where a non-diminutive polyp was recorded.
Methods The development of the procedure questionnaire, by the European Colonoscopy Quality Investigation (ECQI) Group, has been previously presented (UEGW 2015 and 2016). We analysed data collected between 2/6/16 and 30/4/18.
Results Of 6445 procedures, 2621 reported a polyp (40.7%). Polyp size was missing in 35 procedures, leaving 2586 procedures with at least one polyp of known size.
Polyps > 5 mm: 1294 procedures reported at least one polyp > 5 mm: 1156 reported an endoscopic intervention (89.3%), 136 reported that there was no endoscopic intervention (10.5%) while 2 did not answer (DNA, 0.15%).
Of the 138 procedures with a polyp > 5 mm that did not report an endoscopic intervention, there was one procedure in which an immediate complication (vascular syncope) was reported (132 stated no immediate complications, 5 DNA), and 37 who reported a requirement for a non-routine (immediate) repeat procedure (no 93, DNA 8).
Polyps ≥ 20 mm (polyp size ≥ 20 mm is a subset of > 5 mm): 280 procedures reported a polyp ≥ 20 mm: 227 (81.1%) reported an endoscopic intervention while 53 (18.9%) reported that they did not. Tattooing was only reported in 28 procedures (10%). In procedures where there was definitely a non-pedunculated lesion ≥ 20 mm, 19/173 (11.0%) reported tattooing.
Conclusions In procedures reporting non-diminutive polyps, no immediate endoscopic intervention was reported in over 1 in 10 procedures, rising to nearly one in five for procedures reporting a polyp ≥ 20 mm. Our findings indicate that tattooing rates are very low.
