- Abstract: Objective To explore the utility of different endoscopic retrograde cholangiopancreatography(ERCP)complexity scales in the training of endoscopists.Methods Clinical data of 237 patients treated by ERCP completed by trainee physicians at two hospitals in Eastern China from February 2022 to February 2023 were prospectively collected.All ERCP cases were classified using previously proposed complexity grading scales,including the American Society of Gastrointestinal Endoscopy(ASGE),Morriston and HOUSE grading scales,compared with the hepatopancreatic ampulla features classification.Successful intubation,successful surgical treatment and complication rates within 48 h were recorded.Results Within each grading,subgroups were divided according to severity,and the comparison of intubation success rates between subgroups in the 3 different grades showed statistically significant differences(P = 0.000).The treatment success rate and intubation success rate had similar findings(P = 0.000).There was no correlation between the complication rate and ASGE grading(P = 0.361),Morriston grading(P = 0.332),and HOUSE grading(P = 0.586).When only cases with primitive papillae were considered,the intubation success rate depended on the complexity grading after the newly added classification of hepatopancreatic ampulla features.In the ASGE group,the success rate of intubation was compared between different subgroups,and the difference was statistically significant(P = 0.004);in the Morriston group,the success rate of intubation was compared between different subgroups,and the success rate of intubation was statistically significant(P = 0.002);in the HOUSE group,the success rate of intubation was compared between different subgroups,and the difference was statistically significant(P = 0.000);In the hepatopancreatic ampulla characteristics group,the difference in intubation success rate was statistically significant when compared between different subgroups(P = 0.000).Similar findings were also found for treatment success rate and intubation success rate(P = 0.000).There was no correlation between the complication rate and ASGE group(P = 0.586),Morriston group(P = 0.443),HOUSE group(P = 0.306),and hepatopancreatic ampulla characteristics group(P = 0.350).Conclusion The use of hepatopancreatic ampulla features as a classification of biliary cannulation complexity is feasible and could be an alternative or additional means of predicting successful biliary cannulation and surgical treatment success and could be used in the future to assess endoscopist training and learning progress and technical standards.
