Risk factors for post‐endoscopic retrograde cholangiopancreatography complications in very elderly patients aged 90 years or older—No additional risk

Abstract

AimIn recent years, the majority of patients eligible for endoscopic retrograde cholangiopancreatography (ERCP) have been aged ≥75 years. We investigated ERCP safety in very elderly patients (aged ≥90 years).MethodsWe included patients aged ≥75 years who underwent ERCP between January 2015 and December 2020. We compared background factors, comorbidities, ERCP indications, complications, and outcomes and identified risk factors for complications using binary logistic regression and inverse probability of treatment weighting with propensity scores.ResultsThe study included 1344 patients aged ≥75 years (137 and 1207 very elderly and elderly patients, respectively). The very elderly group had more women, less frequent diabetes, fewer antithrombotic medications, more frequent parapapillary diverticulum, less frequent post‐cholecystectomy, and worse performance status. No significant differences were observed in the ERCP indications. Experienced endoscopists were likely to perform the procedure, and the procedure time was shorter for the very elderly. Complications occurred in 21 (15%) very elderly patients and 120 (10%) elderly patients, with no significant differences. The very elderly did not have an increased risk of complications but were less likely to be discharged home and had a significantly worse performance status at discharge.ConclusionsERCP could be safely performed in the very elderly, and age did not increase the risk of complications.
