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.
目的
To assess the benefits and harms of surgical removal of the gallbladder for patients with asymptomatic gallstones.
搜尋策略
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.
選擇標準
Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing cholecystectomy and no cholecystectomy were considered for the review.
資料收集與分析
We were unable to identify any randomised clinical trials comparing cholecystectomy versus no cholecystectomy.
主要結果
We were unable to identify any randomised clinical trial comparing cholecystectomy versus no cholecystectomy.
作者結論
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.
