Background:
The rate of incisional hernia (IH) at stoma site after ileostomy closure is controversial in the literature. We aimed to estimate the prevalence of IH at stoma site after ileostomy reversal and to determine its risk factors.
Material And Methods:
We performed a systematic review according to PRISMA standards to identify studies reporting prevalence of IH after ileostomy closure. Meta-analysis was performed to estimate its rate. Heterogeneity was explained by meta-regression and subgroup analysis.
Results:
Twenty studies were included with 2629 patients. The pooled estimated rate was 13,7% with a 95% confidence interval (11-17%). The 95% prediction interval varied between 5,3% and 31,1%, which showed substantial heterogeneity. Meta-regression showed that ASA score III and IV increases IH rate (p = 0,02). Obese and elderly patients have a tendency for developing IH with substantial heterogeneity. Subgroup analysis for COPD, diabetes mellitus, smoking, laparotomy approach for the initial surgery, did not show statistically significant differences.
Conclusion:
Prevalence of IH is higher than previously estimated in the literature. ASA score III and IV increases its rate. Prospective randomized studies focusing on the impact of prophylactic mesh implementation are necessary.
