摘要

Purpose

Retromuscular ventral hernia repair (RVHR) is a well-established and increasingly popular technique for mesh placement, offering favorable recurrence and complication rates. However, the role of mesh fixation in RVHR remains unclear, as some have questioned its effect on reducing recurrence and could potentially increase postoperative morbidity. We performed a systematic review and meta-analysis to compare outcomes of RVHR with and without mesh fixation.

Methodology

PubMed, EMBASE, and Cochrane Library were searched through July 2025. Eligible studies included adult patients undergoing open RVHR with or without fixation. Primary outcomes were hernia recurrence and postoperative pain; secondary outcomes included hematoma, seroma, surgical site infection (SSI), reoperation, operative time, length of stay (LOS), and quality of life. Risk of bias was assessed using RoB 2 and ROBINS-I. Random-effects models were used, and heterogeneity was quantified using the I2 statistic.

Results

Six studies (15,106 patients; 3,994 without fixation) met inclusion criteria: two randomized controlled trials and four observational cohorts, including one registry study. Recurrence did not differ between fixation and non-fixation (OR 1.1, 95% CI 0.91–1.34; I2 = 0%). Fixation was associated with significantly worse quality-of-life scores (MD –12.71, 95% CI –16.48 to –8.93; p < 0.001; I2 = 0%) and higher hematoma risk (OR 5.18, 95% CI 1.18–22.68; p = 0.03; I2 = 0%). No significant differences were found for pain, SSI, seroma, reoperation, LOS, or operative time.

Conclusion

Our systematic review and meta-analysis identified no difference in recurrence, pain, SSI, or long-term outcomes between mesh fixation and non-fixation in RVHR. However, fixation was associated with significantly worse quality-of-life scores and a higher risk of hematoma. These findings suggest a selective rather than routine use of mesh fixation in RVHR.
