Objective We examined the safety and efficacy of endoscopic stone removal for choledocholithiasis in elderly patients ≥90 years of age with native papilla and compared the outcomes with those in patients 75-89 years of age.
Methods This multicenter retrospective study included 569 patients 75-89 years of age and 126 patients ≥90 years of age who had native papilla and underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis at 3 institutions in Japan between April 2012 and March 2018. The main outcomes assessed were the incidence of post-ERCP complications during hospitalization and outcomes of ERCP in patients ≥90 years of age.
Results Biliary cannulation and subsequent endoscopic sphincterotomy, endoscopic balloon dilation, and endoscopic large balloon dilation were successful in 97.7% of patients 75-89 years of age and in 98.4% of patients ≥90 years of age. There was no significant difference in the incidence of post-ERCP complications between patients 75-89 years of age and those ≥90 years of age (7.7% vs. 9.5%, respectively; p=0.47). Although the rate of use of mechanical lithotripter was not significantly different, the rate of complete stone removal in patients ≥90 years of age was lower than that in patients 75-89 years of age (81.0% vs. 94.9%, respectively; p<0.001). In all cases with incomplete stone removal in both groups, permanent biliary stent placement was successful.
Conclusion ERCP for choledocholithiasis in elderly patients ≥90 years of age is a safe and effective procedure; however, endoscopists should select appropriate strategies after considering each patient's medical condition and background.
