Recommendation statementLevel of evidenceStrength
1.1Competence in colonoscopy is defined as the ability to perform colonoscopy, including all relevant peri-procedural and post-procedural aspects consistent with current BSG colonoscopy best practice standards and guidelines.Very lowStrong
1.2Terminal ileal intubation should be attempted in all cases where indicated. Trainees should attain an unassisted terminal ileal intubation rate of >60% where colonoscopy is indicated for suspected IBD (ie, chronic diarrhoea, iron-deficiency anaemia, abdominal pain, IBD assessment).LowStrong

1.4Competent endoscopists in colonoscopy should be able to demonstrate endoscopic non-technical skills (ENTS) as defined in DOPS and DOPyS.LowStrong
1.5Competence in colonoscopy includes the ability to identify and manage immediate and late complications of the procedure demonstrating effective clinical, endoscopic and Non-Technical Skills (ENTS) to coordinate subsequent action.LowStrong
1.6Competent endoscopists should be able to recognise the adequacy of the endoscopic procedure performed and recommend subsequent action.Very lowStrong
1.7Competence in polypectomy should be based on achieving all competencies defined in the DOPyS form rather than a set minimum number of procedures.Very lowStrong

Trainee simulator-based training should be directly supported by appropriately skilled trainers/supervisors.ModerateStrong
2.7Training in polypectomy should start early during basic colonoscopy training and continue in parallel with this.Very lowStrong
2.8Attendance at a hands on (tissue/tissue-like) model endoscopy course with exposure to differing polyp resection techniques, submucosal injection techniques, haemostatic therapy and tattooing is encouraged.Very lowStrong
2.9Polypectomy training should include skills acquisition in cold snare, hot snare and basic lift assisted polypectomy to a minimum of SMSA level 2.LowStrong
2.10Trainees should receive training in Paris polyp classification and validated optical diagnosis systems. When available, supportive web-based training tools should be used and any relevant modules completed prior to the basic skills course.ModerateStrong
2.11Appropriate discussion and reflection related to polyp classification and management should occur throughout training.Very lowStrong
2.12All parameters described in DOPS/DOPyS should be included during skills training.Very lowStrong
2.13Water-assisted insertion techniques may improve patient comfort levels and technical success, and should form part of training in colonoscopy.LowWeak
2.14Where available, magnetic endoscopic imaging should be used for colonoscopy training and should be preferentially used for training lists.LowWeak
2.15A trainee should undertake a minimum of 280 colonoscopy procedures to be eligible for summative assessment in colonoscopy.LowStrong
2.16Trainees who hold JAG certification in flexible sigmoidoscopy should have a minimum of 200 lifetime colonoscopy procedures to be eligible for summative assessment in colonoscopy.Very lowStrong
2.17A trainee should have a minimum number of dedicated training lists as defined by the JAG training standards.LowStrong
2.18It is recommended that a trainee should receive a minimum of one DOPS per training list.LowWeak
2.19It is recommended that a minimum of one DOPyS should be completed for every training list where a polypectomy has been attempted by a trainee.LowWeak
2.20Trainees must complete a reflection tool on JETS every 50 procedures. This forms a framework for meetings with their endoscopy supervisor every 6 months or less.LowStrong
3.1DOPS should be used as the competency assessment tool in lower gastrointestinal endoscopy.LowStrong
3.2Each formative DOPS should be performed on a single pre-selected case.LowStrong
3.3The last 5 DOPS prior to summative assessment must be rated competent without supervision in>90% of all items, with none requiring maximal or significant supervision.LowStrong
3.4DOPyS should be used as the polypectomy competency assessment tool for both technical and non-technical skills.LowStrong
3.5For competence at SMSA Level 1 polypectomy, a minimum of 2 SMSA Level 1 DOPyS should be competently performed using the following methods: cold snare polypectomy, diathermy-assisted resection of stalked polyps and diathermy-assisted EMR. The last 4 DOPyS (Level 1) should score ‘competent for independent practice’ in all items.Very lowStrong
3.6For competence at SMSA Level 2 polypectomy, a minimum of 2 SMSA Level 2 DOPyS should be competently performed for each of the following methods: cold snare polypectomy, diathermy-assisted resection of stalked polyps and diathermy-assisted EMR. The last 4 DOPyS (level 2) should score ‘competent for independent practice’ in all items.Very lowStrong
3.7Eligibility for summative assessment in colonoscopy may be triggered once the following are met:
  1. Meeting criteria for BSG standards for competence in colonoscopy relevant to trainees—averaged over a 3-month period (ie, unassisted caecal intubation rate 90%+, rectal retroversion 90%+, polyp detection rate 15%+, polyp retrieval rate 90%+, patient comfort: <10% with moderate–severe discomfort)

  2. Attaining minimum colonoscopy procedure count of 280 (200 if certified in flexible sigmoidoscopy)

  3. Have performed at least 15 procedures over the last 3-month period

  4. Attendance of JAG Basic Skills in Colonoscopy course

  5. Terminal Ileum intubation rates (60%+ in suspected IBD)
