Comparison of totally visceral sac separation (TVS) and extended view totally extraperitoneal (e-TEP) repair for umbilical and epigastric hernias: a 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
purposeTotally visceral sac separation (TVS) is a novel concept proposed for hernia repair, preserving the integrity of the posterior rectus sheath (PRS). The aim of this study was to compare the results of TVS with the extended view totally extraperitoneal (e-TEP) method for umbilical and epigastric hernias.
methodsA retrospective comparison analysis was conducted including 45 e-TEP and 43 TVS procedures performed between June 2021 and June 2024. Baseline characteristics, surgical records, and postoperative information were collected and analyzed for both groups from the electronic medical records system.
resultsThe baseline characteristics showed no significant differences. The TVS group had a significantly longer mean operative time (230 (36) minutes vs. 190 (84) minutes, P<0.01) and used a smaller mesh area (120 (10) cm² vs. 130 (20) cm², P<0.01). No significant differences were observed between the two groups in terms of quality of life scores, postoperative length of stay, and medical expenses. One patient in the e-TEP group experienced surgical site and mesh infection, requiring mesh removal and resulting in hernia recurrence.
conclusionDespite its complexity and longer operative time, the TVS approach offers potential advantages in long-term outcomes and complication management for umbilical and epigastric hernias. These findings contribute to the understanding and potential adoption of the TVS technique in hernia repair.
