Abstract
Aim
Temporary stoma formation remains a common part of modern-day colorectal surgical operations. At the time of reversal, a second procedure is required when the bowel is anastomosed and the musculature is closed. The rate of incisional hernia at these sites is 30%–35% with conventional suture closure. Mesh placement at this site is therefore an attractive option to reduce hernia risk, particularly as new mesh types, such as biosynthetic meshes, are available. The aim of this work was to conduct a systematic review and meta-analysis assessing the use of mesh for prophylaxis of incisional hernia at stoma closure and to explore the outcome measures used by each of the included studies to establish whether they are genuinely patient-centred.
Method
This is a systematic review and meta-analysis assessing the published literature regarding the use of mesh at stoma site closure operations. Comprehensive literature searches of major electronic databases were performed by an information specialist. Screening of search results was undertaken using standard systematic review principles. Data from selected studies were input into an Excel file. Meta-analysis of the results of included studies was conducted using RevMan software (v.5.4). Randomized controlled trial (RCT) and non-RCT data were analysed separately.
Results
Eleven studies with a total of 2008 patients were selected for inclusion, with various mesh types used. Of the included studies, one was a RCT, seven were nonrandomized comparative studies and three were case series. The meta-analysis of nonrandomized studies shows that the rate of incisional hernia was lower in the mesh reinforcement group compared with the suture closure group (OR 0.21, 95% CI 0.12–0.37) while rates of infection and haematoma/seroma were similar between groups (OR 0.7, 95% CI 0.41–1.21 and OR 1.05, 95% CI 0.63–1.80, respectively). The results of the RCT were in line with those of the nonrandomized studies.
Conclusion
Current evidence indicates that mesh is safe and reduces incisional hernia. However, this is not commonly adopted into current clinical practice and the literature has minimal patient-reported outcome measures. Future work should explore the reasons for such slow adoption as well as the preferences of patients in terms of outcome measures that matter most to them.
