Optimal port site skin closure method following minimally-invasive surgery: A systematic review and network meta-analysis of randomised clinical trials

Background

For minimally-invasive surgery (MIS), there are numerous acceptable port-site closure techniques with no consensus on the method used.

Aim

To identify optimal port site postoperative wound closure method following MIS with respect to complication rates and cosmetic outcome.

Methods

Network meta-analysis (NMA) was performed in accordance with PRISMA-NMA guidelines for RCTs comparing at least two methods of port-site closure.

Results

Nineteen RCTs were identified evaluating eight methods of wound closure in 1,932 patients; across three types of suture, three forms of tissue glue, staples and paper-tape. At NMA, there was no significant difference in wound complication, infection, dehiscence or pain rate irrespective of closure method, albeit a trend towards higher rate of dehiscence for adhesives. At NMA, wound cosmesis was superior for adhesives at both early and late postoperative follow-up.

Conclusion

This study validates the use of tissue adhesives with respect to primary closure of port sites following MIS while highlighting potential associated risks.
