Abstract

Background The European Society of Gastrointestinal Endoscopy (ESGE) has developed a core curriculum for high quality optical diagnosis training for practice across Europe. The development of easy-to-measure competence standards for optical diagnosis can optimize clinical decision-making in endoscopy. This manuscript represents an official Position Statement of the ESGE aiming to define simple, safe, and easy-to-measure competence standards for endoscopists and artificial intelligence systems performing optical diagnosis of diminutive colorectal polyps (1 – 5 mm). Methods A panel of European experts in optical diagnosis participated in a modified Delphi process to reach consensus on Simple Optical Diagnosis Accuracy (SODA) competence standards for implementation of the optical diagnosis strategy for diminutive colorectal polyps. In order to assess the clinical benefits and harms of implementing optical diagnosis with different competence standards, a systematic literature search was performed. This was complemented with the results from a recently performed simulation study that provides guidance for setting alternative competence standards for optical diagnosis. Proposed competence standards were based on literature search and simulation study results. Competence standards were accepted if at least 80 % agreement was reached after a maximum of three voting rounds. Recommendation 1 In order to implement the leave-in-situ strategy for diminutive colorectal lesions (1–5 mm), it is clinically acceptable if, during real-time colonoscopy, at least 90 % sensitivity and 80 % specificity is achieved for high confidence endoscopic characterization of colorectal neoplasia of 1–5 mm in the rectosigmoid. Histopathology is used as the gold standard. Level of agreement 95 %. Recommendation 2 In order to implement the resect-and-discard strategy for diminutive colorectal lesions (1–5 mm), it is clinically acceptable if, during real-time colonoscopy, at least 80 % sensitivity and 80 % specificity is achieved for high confidence endoscopic characterization of colorectal neoplasia of 1–5 mm. Histopathology is used as the gold standard. Level of agreement 100 %. Conclusion The developed SODA competence standards define diagnostic performance thresholds in relation to clinical consequences, for training and for use when auditing the optical diagnosis of diminutive colorectal polyps.

  • Achieving PIVI and SODA competencies depends on the accuracy of high-confidence diagnoses, as these criteria are solely based on HC cases.

    “Achieving PIVI and SODA competencies depends on the accuracy of high-confidence (HC) diagnoses, as these criteria are solely based on HC cases.2,8”

    From Structured Integration of an Artificial Intelligence-Based System for the Optical Diagnosis of Colorectal Polyps (2026) · cites this paper as [8]

    Figure 2 (page not specified in our copy) defines both SODA competence standards using sensitivity and specificity for high-confidence optical diagnoses, supporting that part of the claim. The Introduction mentions PIVI competence criteria but does not establish in the passages found that they are based solely on high-confidence cases, so the claim about both sets of criteria is not fully supported. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Attaining proficiency in optical diagnosis and meeting the SODA or PIVI standards can be particularly challenging for novices.

    “Attaining proficiency in optical diagnosis and meeting the accurate standards established by Simple Optical Diagnosis Accuracy (SODA) or Preservation and Incorporation of Valuable Endoscopic Innovations (PIVI) can be particularly challenging for novices.2,7,8”

    From Structured Integration of an Artificial Intelligence-Based System for the Optical Diagnosis of Colorectal Polyps (2026) · cites this paper as [8]

    The Introduction (page unavailable) says proficiency requires training and meeting competence standards, and that PIVI criteria are difficult to implement in daily practice. It does not say novices particularly struggle to attain proficiency or meet either standard; the Conclusion and future prospects instead describes SODA standards as achievable. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
