Objective: To examine the association between length of stay (LOS) after lobectomy and operative adverse events and define the best predictors and risk factors associated with prolonged LOS after lobectomy.

Methods: Data from patients undergoing thoracoscopic lobectomy in the Thoracic Surgery Department of our center between January 2015 and December 2021 were retrospectively analyzed. The association between operative adverse events and LOS after lobectomy was explored using receiver operating characteristic (ROC) curves, and multivariate logistic regression analyses were used to identify preoperative risk factors associated with prolonged LOS after lobectomy.

Results: Prolonged LOS after lobectomy was defined as a LOS after lobectomy that is > 3.5 days based on an optimal diagnostic value for operative adverse events (AUC = 0.882). Of the included patients, 20.9% (91/435) exceeded this threshold, of whom 52.7% (48/91) exhibited operative adverse events. The preoperative risk factors associated with prolonged LOS after lobectomy were age≥60 years old (OR = 9.632, 95%CI 1.126-75.66, p = 0.03), being a current smoker (OR = 2.702, 95%CI 1.547-4.72, P < 0.001), an American Society of Anesthesiology (ASA) classification of 2 or higher (OR = 1.845, 95%CI 1.06-3.211, P = 0.03), ASA = 3 (OR = 9.133, 95%CI 3.281-25.425, P < 0.001), and Stage IIIA disease (OR = 6.565, 95%CI 2.823-15.271, P < 0.001). Prolonged LOS after lobectomy was significantly associated with the incidence of different operative adverse events, including conversion to thoracotomy, an operative duration of ≥300 min, blood transfusion events, chest tube drainage time, postoperative complications, and postoperative interventions (P < 0.001).

Conclusion: The risk of prolonged LOS after lobectomy is higher in patients that are ≥60 years old, current smokers, exhibit an ASA classification of 2 or higher, and have a stage IIIA disease. Early identification of these risk factors can enhance the treatment offered to high-risk patients, thereby reducing the rates of operative adverse events and optimizing resource utilization.

Background: Postoperative complications and extended length of stays (LOS) following lobectomy for non-small cell lung cancer (NSCLC) remain significant healthcare and economic burdens, especially in developing countries with limited resources. This study evaluated the effectiveness of enhanced recovery after surgery (ERAS) protocols in addressing these issues.

Methods: This observational study compared two groups of patients, utilizing a prospective arm for ERAS and a retrospective arm for routine care.

Systematic Review of Sublobar Resection for Treatment of High-Risk Patients with Stage I Non-Small Cell Lung Cancer.

Sublobar resection offers a parenchymal-sparing surgical alternative to lobectomy and includes wedge resection and segmentectomy. Sublobar resection has been historically utilized in high-risk patients with compromised lung function; however, the technique is becoming more prevalent for normal-risk patients with peripheral lung tumors < 2 cm. In this article, we summarize the technique of sublobar resection, the importance of surgical margins and lymph node sampling, patient selection, perioperative complications, outcomes, and the impact of sublobar resection on the quality of life.

Article Synopsis
  • * An expert panel from the American Association for Thoracic Surgery reviewed existing literature and reached a consensus on treatment modalities, which include sublobar resection, image-guided thermal ablation (IGTA), and stereotactic ablative radiotherapy (SABR).
  • * The conclusions highlight that surgical approaches are often preferred when safe, but SABR and IGTA can be suitable alternatives; multidisciplinary evaluations and patient preferences play crucial roles in treatment decisions.

Objective: A significant proportion of patients with stage I non-small cell lung cancer (NSCLC) are considered at high risk for complications or mortality after lobectomy. The American Association for Thoracic Surgery (AATS) previously published an expert consensus document detailing important considerations in determining who is at high risk. The current objective was to evaluate treatment options and important factors to consider during treatment selection for these high-risk patients.

Objective: The American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) previously published important considerations in determining who is at high risk for complications or mortality after lobectomy. Sublobar resection, stereotactic ablative radiotherapy, or image-guided thermal ablation is typically considered when the risks associated with lobectomy are high. The current objective was to evaluate important lung-nodule-related factors to consider during treatment selection for high-risk patients with stage I non-small cell lung cancer (NSCLC).
