Association between skin suture devices and incidence of incisional surgical site infection after gastrointestinal surgery: systematic review and network meta-analysis.

Surgical site infections (SSIs) are common complications after abdominal surgery. To compare which suture devices could reduce the incidence of incisional surgical site infections (SSIs) after gastrointestinal surgery using a systematic review and network meta-analysis. The CENTRAL, PubMed, and ICHUSHI-Web databases were searched from January 1^st, 2000, to December 31^st, 2022, for randomized clinical trials (RCTs) comparing the incidence of incisional SSI after gastrointestinal surgery among patients treated with different surgical suture devices, including non-absorbable sutures, absorbable sutures, skin staplers, and tissue adhesives (last searched in August 23^th, 2023). The risk of bias was assessed using the criteria of the Cochrane Handbook for Systematic Reviews of Interventions. To estimate the pooled odds ratios (ORs) for each comparison, a fixed-effect inverse-variance model based on the Mantel–Haenszel approach was employed. A total of 18 RCTs with 5496 patients were included in this study. The overall SSIs in absorbable sutures were significantly lower than those in skin staplers (OR: 0.77; 95% confidence intervals (CI): 0.63–0.95) and non-absorbable sutures (OR: 0.62; 95% CI: 0.39–0.99), whereas SSIs in absorbable sutures were not significantly different from the SSIs in tissue adhesive. The highest P-score was 0.91 for absorbable sutures. A funnel plot for estimating the heterogeneity of the studies revealed that a publication bias would be minimal (Egger test, P = 0.271). This study showed that absorbable sutures reduced incisional SSIs in gastrointestinal surgical operations compared to any other suture devices. [ABSTRACT FROM AUTHOR]
