RESUMO
Objectives: To identify factors associated with prolonged postoperative length of stay (LOS) after VATS lobectomy (VATS-L), explore potential intersurgeon variation in LOS and ascertain whether or not early discharge influences hospital readmission rates. Methods: We conducted a retrospective analysis of patients who underwent VATS-L at a single academic center between 2018 and 2021. Each VATS lobectomy procedure was performed by 1 of 7 experienced thoracic surgeons. The primary end point of interest was prolonged LOS, defined as an index LOS >3 days. Results: Among 1006 patients who underwent VATS lobectomy, 632 (63%) had a prolonged LOS. On multivariate analysis, the factors independently associated with prolonged LOS were: surgeon (P < .001), patient age (odds ratio [OR], 1.03; 95% CI, 1.02-1.06), operation time (OR, 1.01; 95% CI, 1.01-1.01), postoperative complication (OR, 3.60; 95% CI, 2.45-5.29), and prolonged air leak (OR, 8.95; 95% CI, 4.17-19.23). There was no significant association between LOS and gender, body mass index, coronary artery disease, prior atrial fibrillation, American Society of Anesthesiologists score >3, and prior ipsilateral thoracic surgery or sternotomy. There was no association between LOS ≤3 days and hospital readmission (20 [5.3%] vs 39 [5.9%]; OR, 0.88; 95% CI, 0.50-1.53). Conclusions: An intersurgeon variation in postoperative LOS after VATS-L exists and is independent of patient baseline characteristics or perioperative complications. This variation seems to be more closely related to differences in postoperative management and discharge practices rather than to surgical quality. Postoperative discharge within 3 days is safe and does not increase hospital readmissions.
RESUMO
OBJECTIVE: The goal of minimally invasive surgery is to reduce trauma to patients and improve their postoperative outcomes. In this context, the utilization of robot-assisted thoracic surgery (RATS) in the treatment of lung cancer has increased worldwide. The feasibility of single-incision major pulmonary resections by RATS was recently reported, with the objective of minimizing the surgical trauma of the traditional multiportal RATS approach. However, both techniques require intercostal incisions, potentially causing immediate and chronic pain resulting from intercostal nerve injury. To reduce postoperative pain resulting from intercostal approaches, we developed a nonintercostal, outside the thoracic cage (OTC) approach for RATS lobectomy, avoiding intercostal instrumentation. This report aims to describe the results of the first reported series of OTC subcostal RATS lobectomies. METHODS: Retrospective analysis of a series of the first consecutive patients operated on using the novel OTC subcostal RATS lobectomy technique. RESULTS: Between August and December 2022, a total of 10 consecutive cases were analyzed. The median age was 63 (55 to 84) years, the mean body mass index was 29 (24 to 45) kg/m2, and the median American Society of Anesthesiologists score was III (II to IV). No serious adverse events were observed, and there was no conversion of the surgical technique. The mean operative time was 132.6 (98 to 223) min. The median length of stay was 2 days. No pain-related complications, readmissions, or 30-day mortality were observed. CONCLUSIONS: This series demonstrates that OTC RATS lobectomy is feasible and safe. A phase I clinical trial is currently underway to prospectively assess the safety of the technique as well as its clinical relevance.
