Analysis of Modern International Clinical Guidelines for the Diagnosis of Acute Pancreatitis

Acute pancreatitis is a common and potentially life-threatening gastrointestinal disorder that requires prompt and accurate diagnosis to reduce morbidity and mortality. Over the past two decades, several international clinical guidelines have been developed to standardize diagnostic approaches and improve patient outcomes. This article provides a comparative analysis of modern international clinical guidelines for the diagnosis of acute pancreatitis, including recommendations issued by the American College of Gastroenterology, the American Gastroenterological Association, and the Revised Atlanta Classification. The study examines diagnostic criteria, laboratory and imaging modalities, severity assessment tools, and recommended diagnostic algorithms. The analysis demonstrates a high level of consensus regarding core diagnostic criteria, while differences persist in the timing and choice of imaging techniques and the role of prognostic scoring systems. The findings highlight the importance of guideline-based, integrated diagnostic strategies in contemporary clinical practice.
