prophylactic cholecystectomy may be performed for asymp- tomatic cholelithiasis in the following situations:
● large (>3 cm) gallstones;
● choledocholithiasis;
● chronic haemolytic conditions (sickle cell disease, heredi-
tary spherocytosis);
● gallbladder polyps >1 cm in diameter;
● suspicion/risk of malignancy (anomalous pancreatic duc-
tal drainage);
● calcifcation of the wall (porcelain gallbladder);
● some ethnic groups or subjects living in areas with a high
prevalence of gallbladder cancer associated with gallstones (some parts of northern India, Native Americans, Mexican Americans, Colombia, Chile, Bolivia);
● transplant patients (during transplantation);
● bariatric surgery.
