[Gallstones--surgical aspects].

Between 10% to 15% of the adult population develop gallstones. Therefore, cholecystectomy is among the most common operations in general surgery. The diagnosis of cholelithiasis depends on the patient's history, clinical findings, laboratory tests and ultrasound examination. Once diagnosis of symptomatic gallbladder disease has been confirmed, laparoscopic cholecystectomy is the treatment of choice. Its advantages in comparison with open surgery are decreased morbidity, costs and hospital stay. Open cholecystectomy is still the treatment of choice for complicated gallstone disease (i.e. cancer, Mirizzi's syndrome, severe inflammation) and in high-risk patients. In case of acute cholecystitis, early laparoscopic cholecystectomy is a safe procedure and is associated with the same benefits as for symptomatic disease.
