Early clinical outcomes of thoracic surgery using the Saroa surgical system: a single institution retrospective observational study of perioperative outcomes.
Article in Surgical endoscopy, 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
backgroundThe Saroa surgical system is a novel robot-assisted surgical platform characterized by pneumatic actuation and quantitative haptic feedback. Data on its broader consecutive use during early thoracic surgical implementation remain limited. This study evaluated the early perioperative safety and implementation-related outcomes of this platform.
methodsThis single-center retrospective observational study included 72 consecutive patients who underwent thoracic surgery using the Saroa surgical system between July 2023 and April 2026. The primary outcome was postoperative complications of Clavien-Dindo grade II or higher within 30 days. Secondary outcomes included intraoperative adverse events, conversion, perioperative mortality, and system log-based reboot-requiring protective stop events.
resultsThe cohort included 43 lobectomies, 20 segmentectomies, and 9 mediastinal tumor resections. Clavien-Dindo grade II or higher complications occurred in 13 patients (18.1%). Among anatomical pulmonary resection cases, the most common complication was prolonged air leak, occurring in 6 of 63 patients (9.5%). No 30- or 90-day mortality or Clavien-Dindo grade IIIb or higher complications were observed. Intraoperative adverse events occurred in 3 patients (4.2%), all involving vascular injury. Overall conversion occurred in 7 patients (9.7%), including conversion to video-assisted thoracic surgery in 5 and thoracotomy in 2; no emergency conversion occurred. Reboot-requiring protective stop events occurred 30 times in 16 patients. No complications were directly attributed to these events, although one device-related conversion occurred.
conclusionsEarly thoracic surgical implementation of the Saroa surgical system demonstrated an acceptable perioperative safety profile in this consecutive series. Evaluation of novel robotic platforms should include not only conventional perioperative outcomes but also system log-based troubleshooting, system refinement, conversion readiness, and team-based workflow during adoption.
