Minimally invasive management of chronic pleural empyema in non-expandable lung: a systematic review of tunneled pleural catheter use as a surgical alternative.
Synthesis in Langenbeck's archives of 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
backgroundChronic pleural empyema in patients with non-expandable lung represents a major therapeutic challenge, particularly in individuals who are poor surgical candidates. While surgical approaches such as decortication or open window thoracostomy remain standard treatments, minimally invasive strategies are increasingly considered for frail or high-risk patients. Tunneled pleural catheters (TPCs) have emerged as a potential alternative; however, clinical data regarding their efficacy and safety in chronic pleural infection remain limited.
methodsWe conducted a systematic review of studies evaluating the use of TPCs in the management of chronic pleural infections in non-surgical candidates. A comprehensive search was performed in PubMed and other relevant databases up to March 2025. Studies were included if they reported clinical outcomes of TPCs in empyema or pleural infection. Data were extracted on patient characteristics, success rates, complications, and pleurodesis outcomes.
resultsA total of eight studies including 1,141 patients were analyzed. TPCs were associated with infection control in the majority of reported cases, with complete or partial resolution rates of up to 100% in selected cohorts. In the largest study, the infection rate associated with TPCs was 4.9%, with an infection-related mortality of 0.29%. Post-infection pleurodesis occurred in more than 60% of patients. Case reports and small series described effective symptom relief and radiological improvement over follow-up periods ranging from weeks to months. In selected cases, intrapleural fibrinolytics were administered safely via TPCs.
conclusionsTPCs appear to be a feasible and potentially effective management option for carefully selected patients with chronic pleural infection and non-expandable lung who are unfit for surgery. Their use may facilitate ambulatory care, reduce hospitalization, and support pleural symphysis formation in selected cases. Given the limited and predominantly observational nature of the available evidence, TPCs should be considered as part of an individualized, multidisciplinary treatment approach, and further prospective studies are warranted to better define their role alongside other minimally invasive strategies in inoperable pleural empyema.
