RESUMO
In March 2016, we reported the SSI rate at LSU Health for all abdominal wall hernia repairs performed between 2011 and 2013. Among the 263 repairs, the infection rate averaged 6.8 per cent. Given the diversity of repairs, this global percentage lacks relevance, but looking at subsets provides meaningful insights. For example, SSI was 1.8 per cent among 55/263 laparoscopic repairs and 8.2 per cent among 206/263 open repairs. The infection rate of 26.3 per cent among the 19 open component separation cases was especially noteworthy and bothersome. Even though there was no mortality in any subset, the vast majority of the morbidity and costs involved repairs with open component separations. A meta-analysis published in 2016 revealed a likely SSI benefit for the endoscopic component separation technique (ECST) over the open CST. Since that report, we have focused our quality improvement efforts on this subset of challenging cases and have replaced CST with ECST. Our data now include results from 33 hernia repairs with either CST or ECST that were performed between November 2011 and April 2018. Twenty-four of 33 patients had CST with an SSI rate of 37.5 per cent (9 of 24). Nine of 33 had ECST with 0 per cent SSI (P value = 0.039). These results mirror the findings reported in the meta-analysis.
