Abstract
BACKGROUND: the aim of this meta-analysis was to evaluate the postoperative effects of neuromuscular blockade reversal with sugammadex compared with acetylcholinesterase inhibitors in colorectal surgery. METHODS: A systematic literature search was performed for studies comparing the postoperative course of patients receiving neuromuscular blockade reversal with either sugammadex or acetylcholinesterase inhibitors (control) after colorectal surgery. Data from eligible studies were extracted, qualitatively assessed, and included in a meta-analysis. Odds ratios and standardized mean differences with 95% confidence intervals (CIs) were calculated. RESULTS: Five studies with a total of 1969 patients were included (sugammadex n = 1137, control n = 832). Sugammadex reversal resulted in a significantly faster return of defecation or flatus after surgery compared to acetylcholinesterase inhibitors (SMD 13.01, 95% CI 6.55-19.46, p = < 0.0001). There were no significant differences between the two groups in other clinical outcomes such as surgical morbidity and length of hospital stay. CONCLUSION: The present data support the beneficial impact of sugammadex on gastrointestinal motility after colorectal surgery. However, the effect of sugammadex on the prevention of surgical complications and a prolonged hospital stay is diminishing. Larger randomized controlled trials with standardized study protocols are needed to validate the results presented here.
