Dry Medical Thoracoscopy with Artificial Pneumothorax Induction: A Scoping Review.
Article in Tuberculosis and respiratory diseases, 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
backgroundDry medical thoracoscopy (MT) allows access into the pleural cavity in the absence of effusion; but its role, safety, and techniques remain poorly defined. This scoping review summarises current evidence on indications, procedural approaches, diagnostic yield, and safety of dry MT; and highlights gaps to guide future research.
methodsWe conducted a scoping review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. PubMed and Google Scholar databases were systematically searched for original studies reporting on dry MT involving pneumothorax induction. Study selection and data extraction followed the Joanna Briggs Institute methodology.
resultsThirteen studies involving 357 patients were included. 146 cases (40.9%) were completely 'dry' (complete absence of pleural fluid). Techniques for pneumothorax induction varied, including blunt dissection, Veress needle, Boutin needle, bladeless trocar, Saugman cannula and guidewire-assisted catheter insertion. Procedural success ranged from 80.6% to 100%, though definitions were inconsistently reported. Thoracic ultrasound was frequently used for site selection and needle guidance, but standardised criteria were lacking. Malignancy and chronic pleurisy were common histological findings. Complications occurred in 5.9% of cases, most commonly chest pain. No studies reported long-term follow-up.
conclusionDry MT appears technically feasible and generally safe. Heterogeneity in techniques, outcome definitions, and limited follow-up constrain further interpretation. Future studies should aim to standardise procedural definitions, evaluate predictors of success, and compare pneumothorax induction methods. Prospective research with long-term outcomes is needed to definite the role of dry MT more clearly.
