There was no difference in the rates of stomal hernia after 24 months in this study that finally included 135 procedures: 31 per cent versus 28 per cent without mesh. There were no mesh infections.

Comment: It is interesting that there have been numerous RCTs, but with very variable results. This makes it difficult to conduct a systematic analysis, and to provide definitive recommendations.
