Intraoperative recall of surgeon-defined 3-dimensional planning during robotic pulmonary resection: A feasibility study.
Article in JTCVS techniques, 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
Objective: To evaluate the feasibility, usability, and user acceptance of integrating preoperative patient-specific 3-dimensional planning into an intraoperative stereoscopic robotic workflow during pulmonary resection. Methods: We conducted a prospective single-center pilot study of patients scheduled to undergo robot-assisted pulmonary lobectomy or anatomical segmentectomy. Patient-specific pulmonary anatomical models were generated preoperatively and displayed intraoperatively on the robotic surgeon's console using an i-Lung 3-dimensional simulator. Planned transection references for the vascular and bronchial structures were defined using cut rings and recalled during surgery. Questionnaire responses from surgeons and assistants were prospectively collected after each procedure. The outcomes were summarized using descriptive statistics, and no formal hypothesis testing was performed. Results: Sixteen consecutive patients were enrolled; 1 procedure was aborted because of unexpected pleural dissemination. The remaining 15 patients were analyzed. The system was successfully introduced in all 15 procedures, with no conversions, procedure interruptions, technical failures, system crashes, or image display interruptions attributable to the system. All surgeon responses indicated anatomical consistency, no rendering delay interfering with surgery, and no significant visual discomfort. Surgeon-rated depth perception and usefulness of console-based anatomical confirmation were rated 5 in 13 responses and 4 in 2 responses. Interactive functions and future-use items were rated 5 in all surgeon responses. Assistant responses also favored shared stereoscopic visualization. Conclusions: The i-Lung 3-dimensional simulator enabled feasible integration of preoperative patient-specific 3-dimensional planning into the intraoperative stereoscopic robotic console environment. Further studies with objective endpoints are warranted.
