- High or increased risk of malignancy (cancer).
- Sufferer's age above 70.
- Sufferer with Sugar disease (Diabetes): New evidence suggests that cholecystectomy should be done for the same indications as general population. thaere is no need of prophylactis cholecystectomy in asymptomatic gallstones in diabetics..
