Background
The recurrence of stones after endoscopic minimally invasive cholecystolithotomy (EMIC) remains a hazardous problem in patients with cholelithasis. We sought to evaluate the risk factors for recurrence after cholecystolithotomy and to provide a theoretical basis for the indication for cholecystolithotomy.
Methods
We searched the Cochrane Library, PubMed, EMBASE, WanFang Data, CNKI and VIP Data to identify controlled trials related to cholelithasis that were published between 2007 and 2016. The odds ratios (ORs) were calculated with 95% confidence intervals (CIs). Stata12.0 was used to test the heterogeneity and publication bias.
Results
Eight studies involving 1663 participants were selected. No significant differences were observed in hazardous factors including advanced age, gender and diabetes mellitus compared with the control groups. However, family history of cholelithasis, multiple calculi, gallbladder wall thickening (GBWT) over 3 mm, a preference for greasy food, dysfunction of the gallbladder and not taking oral ursodeoxycholic acid post-EMIC yielded pooled ORs (95% CI) of 3.28 (2.30, 4.66), 4.24 (2.76, 6.50), 18.4 (7.23, 46.83), 1.90 (1.20, 3.01), 26.16 (10.15, 62.34) and 2.90 (1.36, 6.15), respectively.
Conclusions
A family history of cholelithasis, multiple calculi, a GBWT ≥ 3 mm, a preference for greasy food, dysfunction of the gallbladder and not taking oral ursodeoxycholic acid post-EMIC are hazardous factors for stones and sludge after cholecystolithotomy.
