30-day outcomes for self-gripping mesh versus non-self-gripping mesh in minimally invasive extraperitoneal ventral hernia repair.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrior work suggests that use of self-gripping mesh (SGM) may be associated with decreased wound complications and pain compared to non-self-gripping mesh (NSGM) after open ventral hernia repair (VHR). Outcomes following minimally invasive (MIS) extraperitoneal VHR are unknown. We hypothesized that use of SGM in MIS extraperitoneal VHR would be associated with decreased wound complications and postoperative pain.
methodsA retrospective cohort study using prospective data from the Abdominal Core Health Quality Collaborative was performed. Adults undergoing clean, elective, MIS retromuscular and/or preperitoneal VHR using permanent synthetic SGM or NSGM were included. Cases with a second mesh, barrier-coated mesh, or anatomic inguinal mesh or without a 30-day follow-up were excluded. 1:1 propensity score matching (PSM) was utilized to generate comparable groups. The primary outcome was 30-day surgical site infection (SSI). Secondary outcomes included surgical site occurrences (SSO), SSO/I requiring procedural intervention (SSOPI), operative time, pain and hernia-related quality of life (HerQLes) at 30 d and 1 year, and hernia recurrence at 1-5 years.
resultsAfter PSM, 1378 patients remained (689 SGM, 689 NSGM). Baseline covariates were well-matched. Operative time was longer for SGM compared to NSGM cases (p = 0.008). Thirty-day SSI, SSO, and SSOPI were rare and comparable between groups. There was no difference in pain or HerQLes scores at 30-day or 1-year follow-up. Hernia recurrence rates were comparable at 1 year; however, SGM had significantly higher rates of hernia recurrence at 2-4 years.
conclusionsThere were no observed clinical advantages to use of polyester-based SGM in MIS extraperitoneal VHR, with a concerning trend toward increased long-term hernia recurrence. Further prospective evaluation and long-term surveillance are needed to define the role of SGM in MIS extraperitoneal VHR.
