Preoperative Factors Associated with Surgical Complexity and Postoperative Outcomes in Patients Undergoing Robotic Anatomical Segmentectomy.

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
objectivesAnatomical segmentectomy is increasingly used for early-stage lung cancer due to its parenchymal-sparing benefits. However, it remains technically challenging, and procedural complexity is often inconsistently defined. Robotic-assisted surgery, offering enhanced dexterity and visualization, has become more widespread but still requires high technical expertise. This study aimed to identify preoperative factors associated with procedural complexity and evaluate its impact on postoperative outcomes.
methodsThis single-centre cohort study included 160 consecutive patients who underwent robotic segmentectomy by 2 expert surgeons between November 2018 and August 2025. Complex procedures were defined as those with operative time >125 min (75th percentile), conversion to another surgical approach, or changes in the planned resection due to intraoperative technical challenges. Logistic regression was used to identify preoperative variables associated with complexity. Postoperative outcomes were compared between complex and non-complex cases.
resultsThirty-seven segmentectomies (23.1%) were classified as complex. Predictors of complexity included age (odds ratio [OR] = 1.042, P = .063), transverse pleural diameter (OR = 0.716, P = .089), and number of staple planes (OR = 1.644, P = .058), while the presence of emphysema (OR = 0.428, P = .076) appeared to be protective. Mortality, overall morbidity, prolonged air leak, and readmission rates were similar between groups. However, complex cases had significantly higher rates of major morbidity (13.5% vs 1.6%, P = .008), reintervention (10.8% vs 0.8%, P = .010), and longer hospital stays (median 3 vs 2 days, P = .004).
conclusionsThis exploratory analysis identified preoperative factors associated with procedural complexity in robotic segmentectomy. These findings may help improve patient selection, surgical planning, resource allocation, and structured training.
