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

Sep 30, 2026

An exploratory single-centre cohort study evaluates how preoperative patient and anatomical factors relate to procedural complexity and how complexity affects postoperative results after robotic anatomical segmentectomy. Complex cases are defined by longer operative time, conversion or changes in planned resection due to intraoperative technical challenges. Among 160 consecutive patients, complex procedures show higher major morbidity, reintervention, and longer hospital stays, while mortality and overall morbidity remain similar.

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. Methods: This 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. Results: Thirty-seven segmentectomies (23. 1%) were classified as complex. Predictors of complexity included age (odds ratio [OR] ¼ 1.042, P ¼ .063), transverse pleural diameter (OR ¼ 0.716, P ¼ .089), and number of staple planes (OR ¼ 1.644, P ¼ .058), while the presence of emphysema (OR ¼ 0.428, P ¼ .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 ¼ .008), reintervention (10.8% vs 0.8%, P ¼ .010), and longer hospital stays (median 3 vs 2 days, P ¼ .004). Conclusions: This exploratory analysis identified preoperative factors associated with procedural complexity in robotic segmentectom

FAQs

What is the purpose of this study on robotic anatomical segmentectomy?

The study aims to identify preoperative factors associated with procedural complexity and assess how complexity influences postoperative outcomes.

How does the study define a “complex” procedure?

Procedures are classified as complex if operative time exceeds 125 minutes, there is conversion to another approach, or intraoperative technical challenges lead to changes in the planned resection.

Which preoperative factors were associated with higher procedural complexity?

Predictors include age, transverse pleural diameter-related measures, and the number of staple planes, while the presence of emphysema appeared protective in the analysis.
