ABSTRACT

OBJECTIVE: To compare the clinical-radiological characteristics and explore the association between therapeutic success in patients undergoing ERCP and age in Cayetano Heredia Hospital, Lima, Peru. MATERIALS AND METHODS: Retrospective, descriptive study based on the review of records of patients undergoing ERCP between the years 2008 to 2014. These were divided into two groups greater than or equal to 60 years (group 1) and less than 60 years (group 2). Indications of ERCP, radiological finding, therapeutic success, diagnostic and complications were documented. RESULTS: A total of 450 patients were studied, the group 1 consisting of 164 and group 2 of 286 patients. The most frequent indication for ERCP in both groups was choledocholithiasis. The most common radiological finding in both groups was bile duct dilatation (p=0.155). The most common diagnosis was choledocholithiasis in both groups, predominantly in group 2. We achieved a complete cleaning of the bile duct in 185(78.75%) patients with choledocholithiasis, finding more patients in group 2 (p=0.008) (OR=0.46; CI 95% 0.25-0.87). The most frequent complication was pancreatitis in both groups (p=0.01). CONCLUSIONS: Choledocholithiasis and pancreatitis were the diagnosis and the most frequent complication. We found that the therapeutic success in patients who presented choledocholithiasis is associated with an age less than 60 years.
