BackgroundGastroesophageal reflux-related chronic cough (GERC), is one common type of chronic cough. Drug treatment is effective for some GERC patients. But, there is refractory GERC (rGERC). For rGERC, fundoplication may be the only effective method. However, there were very few studies about laparoscopic fundoplication in treating rGERC, and the cure rate of fundoplication in treating rGERC was unknown. So there is a question, what is the cure rate of fundoplication in treating rGERC? To solve this question, we performed this meta-analysis.MethodsThe PRISMA strategy and Cochrane collaboration method were used for this study. Our study was registered with PROSPERO (ID: CRD42021251072). We searched PubMed, Medline, Web of Science, and the Cochrane databases from 1990 to December 2022. The meta-analysis was performed with Review Manager 5.4 and Stata 14.ResultsAfter selection and exclusion, 8 articles out of 672 were included. The meta-analysis showed the cure rate of laparoscopic fundoplication in treating rGERC was 62% (95% confidence interval: 53-71%), with no deaths in 503 patients. There was no significant heterogeneity or bias in the meta-analysis.ConclusionsIn terms of safety, laparoscopic fundoplication is quite reliable offered by skilled surgeons. In terms of cure rate, laparoscopic fundoplication could completely heal two-thirds of rGERC patients; however, there are still some patients who can not be completely cured by fundoplication.Copyright © 2023 the Author(s).
