Abstract [en]

To compare circular stapler (CS) with linear stapler (LS) in a meta-analysis concerning operative time, anastomotic leaks, wound infections, strictures, and length of stay. Pubmed, Medline, and Scopus were searched for articles published since 2006. Four hundred and five articles were assessed, and 13 articles of which only one was a randomized controlled trial were included in all 49,331 patients from different regions of the world. The pooled analysis shows that operative time was shorter in LS than in CS (weighted mean difference 36.2min; 95% CI 34.7-37.6.; pamp;lt;0.0001). No difference was seen concerning leaks or strictures. The relative risk (RR) of leakage after LS was 80% of the risk after CS; however, the 95% confidence interval (CI) showed overlap (0.58-1.11). The RR of anastomotic stricture after LS was 74% of the risk after CS; however, 95% CI (0.52-1.05) showed overlap. Wound infections were less common after LS than after CS; RR was 27% (95% CI 0.21-0.33). Length of stay (LOS) was 0.65days shorter after LS than after CS (95% CI 0.51-0.78). LS compared with CS results in shorter operative time, less wound infections, and shorter length of stay, but no difference was seen concerning risks of leaks or strictures.
