Enhanced Recovery Pathway in Lung Resection Surgery: Program Establishment and Results of a Cohort Study Encompassing 1243 Consecutive Patients

SIMPLE SUMMARY: Enhanced Recovery Pathways (ERP) have been scarcely assessed in lung cancer surgery. We performed a two-step audit for our experience: the first dealing with our initial experience focusing on patients undergoing segmentectomies and lobectomies, the second including all subsequent consecutive patients undergoing all kind of lung resections for NSCLC. The first step aimed at auditing results of ERP on occurrence of postoperative complications and at assessing which ERP components were associated with improved short-term outcomes. We also audited late results by assessing long-term survival of patients in the first step of our study. The second step aimed at auditing on large-scale short-term results of the ERP in a real-life setting. In total, 166 patients were included in the first period. No postoperative death occurred. The overall adverse events rate was 30%. In multivariate analyzes, the only element associated with reduced adverse postoperative events was chest tube withdrawal within POD2. The 1-, 3- and 5-year survival rates were 97%, 86.1%, and 76.3%, respectively. In the second period, 1077 patients were included; 11 patients died during the postoperative period. The overall postoperative adverse event rate was 30.3%. Thoracoscore independently predicted postoperative death, the occurrence of complications (all-kind, minor, major, or respiratory ones). We conclude that compliance to ERP procedures and early chest tube removal are associated with reduced postoperative events in patients with lung resection surgery. Thoracoscore is a useful tool in predicting mortality and postoperative adverse events. ABSTRACT: Introduction: In spite of increasing diffusion, Enhanced Recovery Pathways (ERP) have been scarcely assessed in large scale programs of lung cancer surgery. The aim of this study was auditing our practice. Methods: A two-step audit program was established: the first dealing with our initial ERP experience in patients undergoing non-extended anatomical segmentectomies and lobectomies, the second including all consecutive patients undergoing all kind of lung resections for NSCLC. The first step aimed at auditing results of ERP on occurrence of postoperative complications and at assessing which ERP components are associated with improved short-term outcomes. We also audited late results by assessing long-term survival of patients in the first step of our study. The second step aimed at auditing on large-scale short-term results of the ERP in a real-life setting. Results: Over a one-year period, 166 patients were included. The median number of ERP procedures per patient was three (IQR 3–4). No postoperative death occurred. The overall adverse events rate was 30%. In multivariate analyzes, the only element associated with reduced adverse postoperative events was chest tube withdrawal within POD2 (OR = 0.21, 95% CI (0.10–0.46)). The 1-, 3-, and 5-year survival rates were 97%, 86.1%, and 76.3%, respectively. In the second period, 1077 patients were included in our ERP; 11 patients died during the postoperative period or within 30 days of operation (1.02%). The overall postoperative adverse event rate was 30.3%, major complication occurring in 134 (12.4%), and minor ones in 192 (17.8%). Respiratory complications occurred in 64 (5.9%). Thoracoscore independently predicted postoperative death, the occurrence of complications (all-kind, minor, major, or respiratory ones). Conclusions: Compliance to ERP procedures and early chest tube removal are associated with reduced postoperative events in patients with lung resection surgery. In a large setting scale, ERP can be applied with satisfactory results in terms of mortality and morbidity. Thoracoscore is a useful tool in predicting mortality and postoperative adverse events.
