A Case Series and Technical Note on Endoluminal Vacuum Therapy via Pull-Through Technique for Leakage after Metabolic Bariatric Surgery.
Article in Obesity surgery, 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
backgroundEndoluminal vacuum therapy (EVT, Eso-SPONGE MATERIAL &
methodsAll patients treated for leaks after MBS with EVT pull-through technique between 01/2018 and 06/2025 at the Department of General Surgery, Medical University of Vienna (MUV), were included in this retrospective analysis. Statistical analyses were performed descriptively.
results7 patients were treated with EVT via pull-through technique. In 5/7 cases (71.4%), index surgery was a primary MBS and acute leaks occurred in 6/7 cases (85.7%). All patients received surgical reintervention, targeted drainage and EVT (7/7; 100%). Self-expanding metal stent was used in 4/7 cases (57.1%) additionally. EVT was changed 9.6 times (3-33) with EVT duration of 30.8 days (11-97). No severe device-related complications were observed. Successful leak closure with EVT was achieved in 85.7%.
conclusionEVT via pull-through technique is effective and feasible for managing leaks after MBS when targeted drainage is available. It allows precise EVT placement and enhanced tissue healing, potentially reducing necessity for further reoperation in critically ill patients.
