Abstract
Recent guidelines on biliary cannulation are lacking. This guideline is an initiative of the World Endoscopy Organization (WEO) with the involvement of a panel of experts from Asia, Europe, and America. Relevant clinical questions on four areas (post-endoscopic retrograde cholangiopancreatography [ERCP] pancreatitis [PEP] prophylaxis, biliary cannulation techniques, sphincterotomy/papillary balloon dilation, and biliary cannulation in special circumstances) were developed and answered after systematic reviews of the literature and using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Successful biliary cannulation and sphincterotomy are cornerstones of ERCP and are indispensable for almost all therapeutic and advanced diagnostic procedures. However, adverse events, particularly PEP, may commonly occur and impair patients' outcomes. A high cannulation rate and a low rate of PEP are quality indicators for ERCP and should be the goal of all endoscopists. With this guideline we aimed to provide clinical practice advice applicable worldwide, regardless of resources and expertise availability. The main recommendations focus on specific aspects of ERCP, including pre-, intra-, and postprocedural measures to reduce the risk of PEP, the technique for an initial biliary cannulation attempt, options for cannulation in cases of difficult biliary access, alternatives to ERCP in case of failure (percutaneous- and endoscopic ultrasound-guided), and biliary access in altered anatomy (periampullary diverticulum and postsurgical anatomy) and in the presence of duodenal stenosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
