Robotic subxiphoid surgical approach for mediastinal lesions: One-year experience.
Article in World journal of clinical cases, 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
backgroundMedian sternotomy has been considered the gold standard approach for anterior mediastinal tumor resection. However, recent advances in video-assisted thoracoscopic surgery and robotic-assisted thoracoscopic surgery with carbon dioxide insufflation have allowed minimally invasive approaches even for large and locally invasive tumors of the upper-anterior mediastinum. The subxiphoid robotic optical approach is a recently developed technique for accessing the mediastinum. The trans-subxiphoid technique offers excellent exposure of the surgical field, reduces postoperative pain, facilitates specimen retrieval even for large tumors, and potentially improves early surgical outcomes.
aimTo evaluate the safety, feasibility, and outcomes of a robotic subxiphoid approach for the resecting of large/invasive mediastinal tumors.
methodsBetween July 2024 and September 2025, 12 patients underwent subxiphoid robotic mediastinal resection. The diameter of the operated lesions ranged from 30 mm to 70 mm. A 3 cm subxiphoid incision was made at the subxiphoid level for GelPort placement, allowing for optical port access. Two operating ports were placed at the sixth intercostal space bilaterally. Carbon dioxide insufflations (8-10 mmHg) enlarged the surgical field, improving visualization of critical anatomical landmarks, such as the internal mammary arteries and phrenic nerves. This approach allowed complete resection of large or invasive tumors, preserving thoracic stability and reducing the risk of postoperative myasthenic crisis.
resultsThe mean operating time was 170.2 minutes, and the median hospital stay was 3.5 days. No major postoperative complications occurred. Two conversions were necessary: One with a lateral robotic approach due to previous abdominal surgery, and one with a sternotomy for tumor invasion of the aortic arch. Histopathological analysis identified nine thymomas and one solitary fibrous tumor.
conclusionSubxiphoid robotic approach is a safe, effective technique for extended thymectomy, fulfilling both oncological and myasthenia gravis surgical objectives.
