Short-term clinical outcomes of laparoscopic trans-abdominal pre-peritoneal repair using Parietex™ Lap.ProGrip™: a 10-year retrospective study.

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
purposeThe efficacy of self-fixating mesh in laparoscopic inguinal hernia repair remains controversial, and its use is not yet explicitly recommended by international guidelines. The short-term outcomes of patients who underwent trans-abdominal pre-peritoneal (TAPP) repair using Parietex™ Lap.ProGrip™ (Lap.ProGrip) during a 10-year period, were retrospectively analyzed, to evaluate its effectiveness at reducing recurrence and chronic post-operative inguinal pain (CPIP).
methodsData from 965 patients (1,129 hernias), aged ≥ 18 years, who underwent TAPP with Lap.ProGrip between November 2014 and October 2024, were retrieved. The standard post-operative follow-up period was 6 months. The primary endpoint was post-operative recurrence, specifically for large direct hernias (Japan Hernia Society [JHS] M3 type). The secondary endpoint was CPIP, which was defined, based on international guidelines, as pain that persisted for ≥ 3 months, required intervention, and interfered with daily activities. The intra-operative videos of all patients with CPIP were reviewed to identify potential procedural causes.
resultsThe 6-month follow-up completion rate was 88.4%. Although 478 hernias (42.3%) had a defect size ≥ 3 cm, including 149 hernias (13.2%) of JHS M3 type, no early recurrences occurred. Four patients (0.5%) had CPIP. Intra-operative video review revealed that in three of the four patients, electrocautery for hemostasis within the "trapezoid of disaster" was performed, suggesting nerve injury, and no mesh-related displacement or folding was observed.
conclusionsThe self-fixating mesh provides reliable short-term stability, even for large direct hernias. CPIP appears to be more closely associated with intra-operative hemostatic maneuvers than with the mesh.
