Adults undergoing laparoscopic or robotic retromuscular and/or preperitoneal ventral hernia repair with clean wound class, successful fascial closure, and at least 1 year of clinical or patient-reported follow-up.
Care Setting
Care setting described in the source article.
Key Highlights
Retrospective analysis of prospectively collected data from the Abdominal Core Health Quality Collaborative registry.
Included uncoated, permanent synthetic medium- or heavyweight mesh and excluded cases without documented mesh characteristics.
The primary outcome was pragmatic hernia recurrence at 1 year, combining available surgeon-reported and patient-reported assessments.
Secondary outcomes included 30-day surgical-site events, readmission, reoperation, recurrence, pain, and abdominal-wall-specific quality of life.
Propensity score matching was used to create comparable mesh-weight groups.
Guideline-Based Recommendations
Diagnosis
Recurrence assessments included surgeon-reported recurrence based on examination or imaging and patient-reported recurrence using a positive Hernia Recurrence Inventory response.
Pragmatic recurrence combined available surgeon- and patient-reported assessments at each time point.
Management
The study assessed outcomes associated with medium- versus heavyweight mesh in minimally invasive extraperitoneal repair; the supplied content does not report comparative results or a mesh-selection recommendation.
Monitoring & Follow-up
Outcomes included recurrence at 30 days and 1 year.
Pain was assessed with PROMIS Pain Intensity and quality of life with the HerQLes survey at baseline, 30 days, and 1 year.
Risks
The study excluded open repairs, conversions to open repair, multiple-mesh cases, non-clean wound classes, and cases without successful fascial closure.
Patient & Prescribing Data
Adults aged 18 years or older in the ACHQC registry who underwent eligible minimally invasive extraperitoneal ventral hernia repair between 2013 and May 2025 and had at least 1 year of clinical or patient-reported follow-up.
Compared uncoated permanent synthetic medium-weight mesh (40–60 g/m²) with heavyweight mesh (>75 g/m²); the supplied content describes study methods but provides no comparative results.
Clinical Best Practices
The study defined recurrence using surgeon-reported, patient-reported, and pragmatic assessments; these measures should be distinguished when describing its outcomes.
The study population was limited to clean wound class, successful fascial closure, and at least 1 year of clinical or patient-reported follow-up.
Propensity score matching was used to address specified demographic, clinical, and operative factors.
