Awake thoracoscopic mediastinal biopsy in a teenager: a case report.
Article in Journal of pediatric surgery case reports, 2025. 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
Introduction: Mediastinal masses are a common pathology encountered by pediatric surgeons. These masses may cause airway compression that precludes the use of general anesthesia; however, pathologic diagnosis may depend upon tissue obtained only through a surgical biopsy. We describe an innovative technique to obtain adequate tissue for diagnosis from an anterior mediastinal mass in the setting of airway compression. Case presentation: A 13-year-old child presented with three months of chest pain and weakness. Initial workup with chest x-ray identified a mediastinal mass. A chest computerized tomography (CT) revealed a 14.5 by 9.7 cm anterior mediastinal mass causing tracheal compression. Bone marrow and lymph node biopsies were non-diagnostic, and a three-day trial of oral prednisone (40 mg twice daily) had minimal effect on airway compromise. Prominent vasculature precluded a window for safe percutaneous biopsy or through a Chamberlain approach. The patient was taken to the operating room for an awake thoracoscopic biopsy of the mediastinal mass using intravenous ketamine and local anesthesia. The patient was placed in left lateral decubitus position. A 5-mm trocar was placed in the posterior axillary line with two additional 5-mm trocars triangulated posteriorly. Loss of negative intrathoracic pressure allowed for visualization of the mass. Biopsies were taken using laryngeal biopsy forceps and a chest tube was left in place. The patient was discharged home on the first postoperative day after chest tube removal. The pathology was consistent with classic Hodgkin lymphoma, intermediate risk, Stage IIA. The patient was treated with chemotherapy per the AHOD0031 protocol and continues to be followed by the oncology service. Conclusion: Awake, video-assisted thoracoscopic surgery seems to be a feasible option for incisional biopsies in teenagers that have mediastinal tumors causing airway compression precluding the use of general anesthesia.
