Cholestatic liver diseases comprise a heterogeneous group of disorders affecting both adult and pediatric population, characterized by alterations in bile formation, secretion, or flow, leading to the accumulation of bile acids and other toxic substances in the liver. In recent years, advances in new pharmacological therapies, the availability of next-generation genetic sequencing techniques, and the development of specific treatments for genetic cholestasis have transformed the diagnostic and therapeutic approach to these conditions. This document, jointly prepared by the "Asociación Española para el Estudio del Hígado" (AEEH) and the "Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátrica" (SEGHNP), presents a national evidence-based guideline for the diagnosis and management of hepatic cholestasis in Spain. It addresses recommendations for differential diagnosis, diagnostic algorithms, indications for genetic studies, treatment and follow-up criteria in diseases such as primary biliary cholangitis, primary sclerosing cholangitis, genetic cholestasis, intrahepatic cholestasis of pregnancy, and vanishing bile duct syndrome. In addition, recommendations are included for the management of extrahepatic complications, indications for liver transplantation, and special considerations in pregnancy and childhood. The guideline emphasizes the importance of a multidisciplinary approach, the use of non-invasive tools for risk stratification, and the incorporation of new targeted therapies, with the aim of improving the prognosis and quality of life of patients affected by cholestatic liver diseases.
Objective: To evaluate the diagnostic performance of the 2019 American Society for Gastrointestinal Endoscopy (ASGE) criteria for choledocholithiasis in patients with acute biliary pancreatitis (ABP).
Patients and methods: We retrospectively analyzed patients diagnosed with ABP and suspected choledocholithiasis at a tertiary hospital between January and December 2024. Common bile duct (CBD) stones were confirmed by magnetic resonance cholangiopancreatography (MRCP) or computed tomography (CT) followed by endoscopic retrograde cholangiopancreatography (ERCP). Patients were stratified according to ASGE 2019 criteria. Diagnostic accuracy was assessed, and cut-off values for alkaline phosphatase (ALP), total bilirubin (TB), and CBD diameter were determined using receiver operating characteristic (ROC) analysis and logistic regression. Biochemical follow-up was analyzed in intermediate-risk patients without confirmed stones.
Results: A total of 197 patients were included; 52 (26.4%) had confirmed choledocholithiasis. Prevalence was 46.9% in the high-risk group and 22.4% in the intermediate group. High-risk classification showed low sensitivity (28.8%) but high specificity (88.3%). Alkaline phosphatase (ALP) was the only independent predictor (cut-off 518IU/L). In intermediate-risk patients without stones, 95% achieved biochemical normalization within 2 weeks.
Conclusions: ASGE 2019 criteria overestimate the risk of choledocholithiasis in ABP, particularly in intermediate-risk patients. Early biochemical follow-up may avoid unnecessary imaging and procedures in this group, while ALP remains the most consistent independent predictor. These results support more conservative and cost-effective management strategies in ABP.
