Validation of Tokyo guidelines 2018 for safety and mortality benefit from urgent ERCP in acute cholangitis across different age groups

BackgroundThe 2018 Tokyo Guidelines (TG18) recommend urgent endoscopic biliary drainage based on acute cholangitis (AC) severity. Therefore, we evaluated the safety and mortality benefits of urgent endoscopic retrograde cholangiopancreatography (ERCP) in different age groups. MethodsUsing International Classification of Diseases-10 (ICD-10) codes, we sampled adult AC patients from National Inpatient Sample. TG18 definition of cholangitis severity was used to identify patients with severe and nonsevere (mild or moderate) AC. Age categories were 18-64, 65-79, and 80 and above. Multivariate linear or logistic regression was used as appropriate. We used Stata, version 14.2, to perform analyses considering two-sided p < .05 as statistically significant. ResultsAmong 137 100 patients, there were 93 365 (68.09%) patients with nonsevere cholangitis and 43 735 (31.91%) patients with severe cholangitis. Urgent ERCP (within 24 h) resulted in decreased mortality in all age groups for both severe and nonsevere AC. Post-sphincterotomy bleeding was more common in patients >= 80 years of age, whereas post-ERCP acute cholecystitis was more common in patients 65-79 years. The rates of post-ERCP pancreatitis, bile duct perforation, and duodenal perforation did not differ among the age groups. In addition, there were no differences in the rate of sedation-related complications between different age groups who underwent urgent ERCP. ConclusionThis study demonstrates the mortality benefit from urgent ERCP for AC in different age groups and describes the safety of performing urgent ERCP in patients of various ages. Therefore, we recommend that urgent ERCP be performed according to the TG18 guidelines regardless of age.
