1 · What the graph read from it

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.

2 · The registry

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

backgroundIn complex ventral hernias, tension-free midline fascial re-approximation may remain unattainable despite posterior component separation (PCS) with transversus abdominis release (TAR). We describe a technique and our initial experience using the entire peritoneal sac as a free flap to augment repair in this setting.

methodsThis retrospective single-center study included all consecutive patients who underwent PERitoneal Free Flap (PERFF) reconstruction between January 2024 and January 2025. Demographics, hernia characteristics, operative details, and post-operative outcomes-including complications (Clavien-Dindo classification), surgical site infection, seroma, hematoma, and hernia recurrence-were analyzed.

resultsEight patients underwent ventral hernia repair using PERFF. The mean age was 68.1 years (range, 57-82), and the mean body mass index was 32.5 kg/m² (range, 27-43). The mean defect width was 6.6 cm (range, 5-15 cm), defect sizes ranged from 5 × 5 cm to 12 × 15 cm, and the Tanaka index ranged from 0.25 to 0.45. Six patients required bilateral TAR and two unilateral TAR. Two patients underwent concomitant small bowel resection. All patients were discharged by post-operative day 3. No post-operative complications or hernia recurrences were observed during a mean follow-up of 17.6 months.

conclusionPERFF is a feasible and safe adjunct to augment PCS with TAR in complex ventral hernia repair when midline closure is not achievable. Harvesting the entire peritoneal sac as a free flap provides flexible and durable fascial coverage while maintaining separation of the mesh from visceral and subcutaneous tissues.
