Directly Observed Polypectomy Skills (DOPyS) is a validated tool used to assess polypectomy
skills in the UK(1). DOPyS has 34 parameters measuring technical & non-technical polypectomy
skills and an overall polypectomy proficiency score on which a trainee is scored on
a grade of 1-4. Trainees are certified as competent in level 1 (<1cm) & level 2 (1-2cm)
polypectomy if they achieve overall scores 3 or 4 in their last 4 consecutive DOPyS,
alongside other key performance indicators. Stable colonoscope position, tip control,
cecal intubation rate (CIR), variability in endoscopic technique & time spent to examine
the polypectomy site have all been suggested as factors critical in competent polypectomy(2),
however, there is currently no literature on trainees’ skill-set or learning curve
required to achieve safe & competent polypectomy.
