OBJECTIVE
To assess the efficacy of the mesh fixation technique on abdominal adhesions in IPOM hernia repair.
MATERIAL AND METHODS
The protocol has been developed following the PRISMA guidelines. Electronic searches over the past 20 years were performed in the Web of Science, Scopus, PubMed, RSCI databases. The methodological quality of the articles was assessed using a scoring system based on SYRCLE’s risk of bias tool. The conclusion about the severity of abdominal adhesion was made based on the following parameters: 1) quantity (No. of pieces of mesh with adhesions); 2) extent (percentage of the surface); 3) type (appearance); 4) tenacity (resistance to lysis); 5) organ involvement. In all studies, at least two types of fixation were assessed.
RESULTS
The search in databases yielded 22 experimental studies. Clinical trials that met the inclusion criteria were not found. Mesh fixation was predominantly performed by transfascial sutures, titanium tacks, absorbable tacks, fibrin sealant, and cyanoacrylate glue. Only three studies had a low risk of bias. In 36.36% of the studies, there was no association between mesh fixation and abdominal adhesion. The most positive effect was obtained when using fibrin glue.
CONCLUSION
After analyzing experimental studies evaluating the effect of mesh fixation on adhesion formation, methods that give both a positive trend (fibrin glue) and methods that have risks (transfascial sutures) were identified. The performed systematic analysis showed that the experimental study of adhesion formation issues with different variants of intraperitoneal mesh fixation had been reserved for development. The lack of targeted clinical studies on this topic is the basis for their implementation.
