Abstract

Background and aims: Gallstones are one of the most common and costly diseases of the gastrointestinal tract and occur when a combination of deposits consisting of fat or minerals accumulate in the gallbladder or common bile duct (CBD). This paper provides a comprehensive review of gallstone epidemiology, diagnosis, and management, focusing on current clinical guidelines and evidence-based approaches. Methods: A systematic literature review gathered information from various sources, including PubMed, Trip, Google Scholar, Clinical Key, and reputable medical association websites. Keywords related to gallstones, CBD stones, cholelithiasis, choledocholithiasis, and guidelines were used to extract relevant recommendations. Expert consultations and consensus meetings localized the recommendations based on the target population and available resources. Results: The paper discusses demographic factors, dietary habits, and lifestyle influences contributing to gallstone formation. Gallstones are categorized into cholesterol and pigment types, with varying prevalences across regions. Many individuals with gallstones remain asymptomatic, but complications can lead to serious and potentially life-threatening conditions. Diagnosis relies on history, physical examination, laboratory tests, and transabdominal ultrasound. Specific predictive factors help categorize patients into high, moderate, or low probability groups for CBD stones. Conclusion: Evidence-based recommendations for gallstone diagnosis and management are presented, emphasizing individualized treatment plans. Surgical interventions, nonsurgical treatments like oral litholysis with UDCA, and stenting are discussed. The management of gallstones in pregnant women is also addressed, considering the potential risks and appropriate treatment options during pregnancy.
