Thoracoscopic repair of chronic post-traumatic diaphragmatic hernia: outcomes and selection criteria.
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
backgroundChronic post-traumatic diaphragmatic hernia is a delayed consequence of missed diaphragmatic injury that presents months to years after trauma. It develops in a stable anatomical setting with mature adhesions and organ migration, creating operative conditions distinct from emergency management of acute rupture.
objectiveTo evaluate the feasibility and perioperative outcomes of video-assisted thoracoscopic surgery for chronic diaphragmatic hernia and to identify anatomical factors that guide selection between minimally invasive and open repair.
methodsFrom January 2010 to May 2026, 21 consecutive patients underwent elective repair at a single center. Approach selection considered defect size, chronicity, adhesion extent, organ viability, and the anticipated ability to achieve tension‑free defect closure. Outcomes were described for thoracoscopic repair completed without conversion (n = 15) and open thoracotomy (n = 5). One hybrid procedure that begun thoracoscopically and proceeded with conversion under continued video guidance was reported separately.
resultsThoracoscopic repair was completed in 15 patients with defects measuring 20-100 mm. Five patients underwent planned open thoracotomy for larger or more complex defects ranging from 20 to 200 mm. Thoracoscopic repair was associated with lower median blood loss (10 vs 200 mL), shorter chest tube duration (1 vs. 4 days), and shorter hospital stay (5 vs. 10 days). A 100 mm right-sided defect with hepatic herniation was repaired thoracoscopically, indicating that defect size alone does not preclude minimally invasive repair. No recurrences, conversions for hemodynamic instability, or deaths occurred during follow-up.
conclusionsIn chronic diaphragmatic hernia, the absence of acute hemorrhage, instability, and visceral compromise favors minimally invasive repair. Thoracoscopic repair appeared feasible in selected patients, whereas larger or complex defects were generally managed by open reconstruction. These findings generate hypotheses and require confirmation in larger prospective studies.
