Postoperative pain management after VATS for spontaneous pneumothorax - a systematic review.
Synthesis in BMC anesthesiology, 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
backgroundHistorically, thoracic epidural analgesia has been the standard for postoperative pain management after surgery for spontaneous pneumothorax. With the advent of enhanced recovery after thoracic surgery protocols, less invasive locoregional analgesic techniques are increasingly considered. Due to lack of high-quality evidence, current guidelines do not address optimal analgesic strategies in this population. This systematic review evaluated the effectiveness of various analgesic techniques following video-assisted thoracoscopic surgery for spontaneous pneumothorax.
methodsMedline, Embase and Cochrane databases were searched until May 2025. Inclusion criteria were patients undergoing video-assisted thoracoscopic surgery for spontaneous pneumothorax, with clearly described postoperative analgesic management (e.g. epidural, locoregional, systemic) and pain scores (visual analgesic score or numeric pain rating score) within 48 h. The primary outcome was pain scores within 48 h postoperatively; secondary outcomes included adjunct analgesic use and complications. Risk of bias was assessed for the primary outcome.
resultsThirty studies comprising 3,203 patients were assessed: risk of bias was low in 3, moderate/some concerns in 24 and high in 3 studies. There were 10 comparative studies and 20 single-arm cohort studies applying solely systemic analgesia (n = 14) or locoregional analgesia (n = 6). No single-arm cohort study applied solely epidural analgesia. Postoperative pain scores within 48 h were higher after systemic analgesia only, compared to the addition of locoregional or epidural analgesia. No clear differences were observed in analgesia-related complications between the analgesic techniques.
conclusionsLocoregional or epidural analgesia as part of a multimodal regimen was associated with the lowest postoperative pain scores, although differences were small. Substantial heterogeneity and low certainty of evidence precluded definitive recommendations. This review provides a foundation for future research investigating optimal analgesic strategies following surgery for spontaneous pneumothorax.
