What this trial studies

This observational study aims to optimize the evaluation and management of patients suspected of having choledocholithiasis, which involves stones in the common bile duct. The study will consist of two phases: a retrospective evaluation of 1,000 patients from 2012 to 2017 to assess the performance of current guidelines, followed by a prospective validation of a new model that incorporates dynamic liver enzyme changes into the management algorithm. The goal is to enhance the accuracy of risk stratification for patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are suspected of having choledocholithiasis, regardless of the probability of the condition.

Not a fit: Patients who are unable or unwilling to provide informed consent, those under 18 years of age, or individuals with suspected or proven cholangitis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved patient outcomes by ensuring that only those with a high likelihood of choledocholithiasis undergo ERCP, thereby reducing unnecessary procedures and associated risks.

How similar studies have performed: Other studies have shown success in optimizing management strategies for choledocholithiasis, but this specific approach incorporating dynamic liver enzyme changes is novel.
