Endoscopic Characterization of Giant Choledocholithiasis and Its Correlation With Primary Choledocholithiasis.

Introduction: Gallstone disease is extremely prevalent in Western society, and the prevalence of common bile duct (CBD) stones with concomitant cholelithiasis increases significantly in the elderly. Different variants influence the treatment of this pathological entity, such as the origin of the stones, their location and quantity, comorbidities of the patient, impaction, and size of the lithos, the latter being an independent predictive factor. In most situations, choledocholithiasis can be resolved with endoscopic retrograde cholangiopancreatography (ERCP); however, in complex cases, such as giant choledocholithiasis (GC), advanced surgical, endoscopic, and percutaneous techniques are required to remove gallstones.
