Cholecystectomy is currently advised only for symptomatic gallstones. However, about 4% of patients with asymptomatic gallstones develop symptoms including cholecystitis, obstructive jaundice, pancreatitis, and gallbladder cancer. Literature search was performed for evidence from randomised clinical trials to find whether cholecystectomy was indicated in patients with silent (asymptomatic) gallstones. There is no randomised trial comparing cholecystectomy versus no cholecystectomy in silent gallstones. Further evaluation of observational studies, which measure outcomes such as obstructive jaundice, gallstone-associated pancreatitis, and/or gall-bladder cancer for sufficient duration of follow-up is necessary before randomised trials are designed in order to evaluate whether cholecystectomy or no cholecystectomy is better for asymptomatic gallstones.

Cholecystectomy is currently advised only for patients with symptomatic gallstones. However, about 4% of patients with asymptomatic gallstones develop symptoms including cholecystitis, obstructive jaundice, pancreatitis, and gallbladder cancer.
Objectifs
To assess the benefits and harms of surgical removal of the gallbladder for patients with asymptomatic gallstones.
Stratégie de recherche documentaire
We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until May 2008.
Critères de sélection
Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing cholecystectomy and no cholecystectomy were considered for the review.
Recueil et analyse des données
We were unable to identify any randomised clinical trials comparing cholecystectomy versus no cholecystectomy.
Résultats principaux
We were unable to identify any randomised clinical trial comparing cholecystectomy versus no cholecystectomy.
Conclusions des auteurs
There are no randomised trials comparing cholecystectomy versus no cholecystectomy in patients with silent gallstones. Further evaluation of observational studies, which measure outcomes such as obstructive jaundice, gallstone-associated pancreatitis, and/or gall-bladder cancer for sufficient duration of follow-up is necessary before randomised trials are designed in order to evaluate whether cholecystectomy or no cholecystectomy is better for asymptomatic gallstones.
