No increased risk of perforation during colonoscopy in patients undergoing propofol versus traditional sedation: A meta-analysis.

BACKGROUND AND AIMS: The safety of propofol sedation during colonoscopy remains unclear, and we performed a meta-analysis to assess the risk of perforation in patients undergoing propofol vs. traditional sedation.

METHODS: MEDLINE, CBM, VIP, CNKI, and Wanfang databases were searched up to December 2016. Two reviewers independently assessed abstract of those searched articles. Data about perforation condition in propofol and traditional sedation groups were extracted and combined using the random effects model.

RESULTS: A total of 19 studies were included in the current meta-analysis. Compared to traditional sedation, propofol sedation did not increase the risk of perforation (RD = - 0.00, 95% CI - 0.00~0.00, p = 0.98; subgroup analysis: OR = 1.30, 95% CI 0.83~2.05, p = 0.25).

CONCLUSION: This meta-analysis suggested that propofol sedation did not increase the risk of perforation compared to traditional sedation during colonoscopy.
