Abstract:

Objective

To systematically evaluate the safety and efficacy of prophylactic mesh placement during permanent colostomy in preventing parastomal hernia (PSH).

Methods

A systematic search of English database (PubMed, Science Citation Index, Cochrane, EMBASE) and Chinese database (CNKI, Wanfang, VIP and CBM) was conducted for randomized controlled trials (RCTs) concerning prophylactic mesh placement during permanent colostomy for prevention of PSH, which published from the establishment of the database to July 2021. Two independent investigators evaluated the quality of the included literature and extracted data. Data were analyzed using Stata 13 and Revman 5.3 software.

Results

A total of 14 RCTs involving 1280 patients were included. There were 625 patients in the mesh group (who received prophylactic mesh placement) and 655 patients in the control group (who did not receive mesh placement). The results of meta-analysis revealed that prophylactic mesh group had lower incidence of PSH (RR=0.49, 95% CI 0.37-0.64, P<0.000 01) and lower incidence of PSH requiring repair (RR=0.25, 95% CI 0.13-0.51, P=0.0001) than those in the control group. There were no statistically difference between mesh group and control group for the incidence of stoma related infection (RR=0.90, 95% CI 0.38-2.13, P=0.81), stomal necrosis (RR=0.76, 95% CI 0.41-1.43, P=0.40), stomal retraction (RR=1.42, 95% CI 0.55-3.64, P=0.47), stoma skin and mucosa dehiscence (RR=1.21, 95% CI 0.64-2.30, P=0.56), stoma prolapse (RR=0.46, 95% CI 0.21-1.05, P=0.06) and stoma stenosis (RR=1.31, 95% CI 0.62-2.79, P=0.48).

Conclusion

Prophylactic mesh placement during permanent colostomy can prevent PSH after surgery, which is a safe and feasible method, but further high-quality and large sample studies are still required to verify the conclusion.
