Abstract
Background: Despite considerable progress in surgical techniques, anastomotic leak (AL) is a common complication after gastrointestinal surgery. Stem cells are a promising therapy to improve healing and have been used in gastrointestinal anastomoses. In this study, we perform a systematic review and meta-analysis to evaluate the efficacy of stem cell therapies in preventing ALs among animal studies.
Methods: A systematic review of the literature was performed by searching PubMed, Web of Science, and the Cochrane Library. We considered all anastomoses of the gastrointestinal tract (excl. biliary) from the esophagus to the rectum. Outcomes included AL rates on postoperative day (POD) 7 and the latest time point reported.
Results: Fourteen studies were identified, evaluating stem cells in gastrointestinal anastomoses, of which 1 was on esophageal, 2 on gastric, 2 on small intestinal, and 9 on colorectal anastomoses. Meta-analysis did not show significant differences in AL rates on POD 7 (odds ratio [OR] 0.34, 95% confidence interval [CI]: 0.04-3.15, p = 0.248, I2 = 34.1%, 95% CI: 0-75.2%, Q = 6.07, df = 4, p = 0.194), but there was a nonsignificant trend for lower AL rates at the latest time point reported (OR 0.28, 95% CI: 0.08-1.01, p = 0.052, I2 = 34%, 95% CI: 0-70.8%, Q = 10.6, df = 7, p = 0.157).
Conclusion: Stem cell therapy may be associated with lower AL rates in gastrointestinal anastomoses, though meta-analysis is severely inhibited by heterogeneous study design. More studies are needed to determine the therapeutic potential of stem cells.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
