摘要

Background

Although an artificial intelligence-driven three-dimensional reconstruction system (AI-3D) facilitates preoperative planning, its impact on consistency between planned and actual surgical procedures and perioperative outcomes has not been sufficiently investigated.

Methods

This study retrospectively analyzed 1197 patients scheduled for segmentectomy (n = 479) or lobectomy (n = 718) between July 2022 and September 2023. The patients were divided into AI-3D and two-dimensional computed tomography (2D-CT) groups. The primary endpoint was the rate of unexpected procedural changes. The secondary endpoints included intraoperative outcomes (operative time, intraoperative blood loss, and the rate of conversion to open surgery) and postoperative outcomes (second operation, second chest tube, drainage volume, and so forth). Propensity score-matching (PSM) was used to minimize selection bias.

Results

Among the patients scheduled for segmentectomy, the AI-3D group demonstrated significantly higher consistency between planned and actual procedures than the 2D group (after PSM: 97.3 % vs 80.0 %; P < 0.001). Reason analysis indicated that most changes were attributable to tumor location and/or surgical margin factors. Intra- and postoperative outcomes were almost comparable between the two groups.

Conclusions

In this study, AI-driven 3D reconstruction significantly reduced the rate of unexpected procedural changes in segmentectomy. Although it ensured higher surgical reliability in relation to the preoperative plan, it did not show an advantage in terms of other intra- and postoperative outcomes.
