To evaluate 30-day postoperative outcomes following minimally invasive retrorectus and preperitoneal ventral hernia repair, comparing self-gripping mesh (SGM) versus non-self-gripping mesh (NSGM).
Approach:
Study Design: Retrospective cohort study utilizing data from the Abdominal Core Health Quality Collaborative (ACHQC) database.
Inclusion Criteria: Adult patients (≥ 18 years) who underwent VHR with clean wound class via MIS extraperitoneal approach with documented mesh type.
Exclusion Criteria: Cases involving second mesh, barrier-coated mesh, missing mesh characteristics, or non-clean wound class procedures.
Statistical Analysis: Propensity score matching and multiple imputation were used to adjust for confounding variables.
Key Findings:
The primary outcome was 30-day surgical site infection (SSI).
Secondary outcomes included 30-day surgical site occurrences (SSO), SSI or SSO requiring procedural intervention (SSOPI), operative time, and reoperation rates at 30 days and 1 year.
Hernia recurrence was evaluated at 30 days and up to 5 years post-surgery, classified as patient-reported, surgeon-reported, and pragmatic recurrence.
Interpretation:
The clinical benefits of SGM versus NSGM in minimally invasive ventral hernia repair are not definitively established.
Limitations:
Retrospective nature of the study.
No pre-specified power analysis was performed.
Conclusion:
The study seeks to clarify the comparative outcomes of SGM and NSGM in minimally invasive ventral hernia repair.
