The management of gallbladder polyp is controversial. Removal of the gallbladder (cholecystectomy) for gallbladder polyps larger than 10 mm has been recommended because of the association between polyps larger than 10 mm and gallbladder cancer. Cholecystectomy is often recommended for patients with biliary type pain and polyps smaller than 10 mm. There has been no randomised clinical trial comparing cholecystectomy with observation for gallbladder polyps. Randomised clinical trials with low bias-risk (low likelihood of systematic error) are necessary to evaluate the role of cholecystectomy in gallbladder polyps smaller than 10 mm.

The management of gallbladder polyps is controversial. Cholecystectomy has been recommended for gallbladder polyps larger than 10 mm because of the association with gallbladder cancer. Cholecystectomy has also been suggested for gallbladder polyps smaller than 10 mm in patients with biliary type of symptoms.
Matlamat
The aim of this review is to compare the benefits (relief of symptoms, decreased incidence of gallbladder cancer) and harms (surgical morbidity) of cholecystectomy in patients with gallbladder polyp(s).
Kaedah Pencarian
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 July 2008 to identify the randomised trials.
Kriteria Pemilihan
Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing cholecystectomy and no cholecystectomy were considered for the review.
Pengumpulan Data dan Analisis
We planned to collect the data on the characteristics, methodological quality, mortality, number of patients in whom symptoms were improved or cured from the one identified trial. We planned to analyse the data using the fixed-effect and the random-effects models using RevMan Analysis. For each outcome we planned to calculate the risk ratio (RR) with 95% confidence intervals based on intention-to-treat analysis.
Keputusan Utama
We were unable to identify any randomised clinical trials comparing cholecystectomy versus no cholecystectomy in patients with a gallbladder polyp.
Kesimpulan Pengarang
There are no randomised trials comparing cholecystectomy versus no cholecystectomy in patients with gallbladder polyps. Randomised clinical trials with low bias -risk are necessary to address the question of whether cholecystectomy is indicated in gallbladder polyps smaller than10 mm.
