Robotic versus thoracoscopic combined anatomic subsegmentectomy for early-stage lung cancer: early results of a cohort study.

ABSTRACT:

Background

Combined anatomic subsegmentectomy performed by video-assisted thoracic surgery or robot-assisted thoracic surgery is an emerging minimally invasive surgical technique for patients with early-stage non-small cell lung cancer (NSCLC). However, the early results of these two methods have barely been studied.

Methods

A retrospective analysis of medical records from Shanghai Ruijin Hospital between July 2017 and August 2021 included 62 patients, 32 of whom underwent video-assisted combined anatomic pulmonary subsegmentectomy and 30 underwent robot-assisted combined anatomic pulmonary subsegmentectomy. Perioperative outcomes were compared.

Results

Sixty-two patients with comparable baseline characteristics were included in this study. No signiﬁcant difference was found in the length of postoperative hospital stay, operation duration, intraoperative blood loss and the rate of overall complications between the robot-assisted and video-assisted groups. A higher cost was observed in the robot-assisted group compared to the video-assisted group. There were more N1 lymph nodes and N1 stations dissected in the robot-assisted group compared with the video-assisted group; the same results were observed with regard to the number of N2 lymph nodes and N2 stations dissected.

Conclusions

It is safe and feasible for the patients with early-stage NSCLC to be treated with combined anatomic subsegmentectomy performed via robot-assisted or video-assisted thoracic surgery. The robotic approach may contribute to the potential improvements in N1 and N2 lymph node retrieval.

Project description:Introduction: Robotic and thoracoscopic surgery are being increasingly adopted as minimally invasive alternatives to open sternotomy for complete thymectomy. The superior maneuverability range and three-dimensional magnified vision are potential ergonomical advantages of robotic surgery. To compare the ergonomic characteristics of robotic versus thoracoscopic thymectomy, a previously developed scoring system based on impartial findings was employed. The relationship between ergonomic scores and perioperative endpoints was also analyzed. Methods: Perioperative data of patients undergoing robotic or thoracoscopic complete thymectomy between January 2014 and December 2022 at three institutions were retrospectively retrieved. Surgical procedures were divided into four standardized surgical steps: lower-horns, upper-horns, thymic veins and peri-thymic fat dissection. Three ergonomic domains including maneuverability, exposure and instrumentation were scored as excellent(score-3), satisfactory(score-2) and unsatisfactory(score-1) by three independent reviewers. Propensity score matching (2:1) was performed, including anterior mediastinal tumors only. The primary endpoint was the total maneuverability score. Secondary endpoints included the other ergonomic domain scores, intraoperative adverse events, conversion to sternotomy, operative time, post-operative complications and residual disease. Results: A total of 68 robotic and 34 thoracoscopic thymectomies were included after propensity score matching. The robotic group had a higher total maneuverability score (p = 0.039), particularly in the peri-thymic fat dissection (p = 0.003) and peri-thymic fat exposure score (p = 0.027). Moreover, the robotic group had lower intraoperative adverse events (p = 0.02). No differences were found in residual disease. Conclusions: Robotic thymectomy has shown better ergonomic maneuverability compared to thoracoscopy, leading to fewer intraoperative adverse events and comparable early oncological results.

Project description:RATIONALE:Video-assisted thoracoscopic surgery (VATS) and open lobectomy are both standard of care for the treatment of early-stage non-small cell lung cancer (NSCLC) because of equivalent long-term survival. OBJECTIVES:To evaluate whether the improved perioperative outcomes associated with VATS lobectomy are explained by surgeon characteristics, including case volume and specialty training. METHODS:We analyzed the Surveillance, Epidemiology, and End Results-Medicare-linked registry to identify stage I-II NSCLC in patients above 65 years of age. We used a propensity score model to adjust for differences in patient characteristics undergoing VATS versus open lobectomy. Perioperative complications, extended length of stay, and perioperative mortality among patients were compared after adjustment for surgeon's volume and specialty using linear mixed models. We compared survival using a Cox model with robust standard errors. RESULTS:We identified 9,508 patients in the registry who underwent lobectomy for early-stage NSCLC. VATS lobectomies were more commonly performed by high-volume surgeons (P < 0.001) and thoracic surgeons (P = 0.01). VATS lobectomy was associated with decreased adjusted odds of cardiovascular complications (odds ratio [OR] = 0.65; 95% confidence interval [CI] = 0.47-0.90), thromboembolic complications (OR = 0.47; 95% CI = 0.38-0.58), extrapulmonary infections (OR = 0.75; 95% CI = 0.61-0.94), extended length of stay (OR = 0.47; 95% CI = 0.40-0.56), and perioperative mortality (OR = 0.33; 95% CI = 0.23-0.48) even after controlling for differences in surgeon volume and specialty. Long-term survival was equivalent for VATS and open lobectomy (hazard ratio = 0.95; 95% CI = 0.85-1.08) after controlling for patient and tumor characteristics, surgeon volume, and specialization. CONCLUSIONS:VATS lobectomy for NSCLC is associated with better postoperative outcomes, but similar long-term survival, compared with open lobectomy among older adults, even after controlling for surgeon experience.

Project description:ObjectiveNonintubated anesthesia, electromagnetic navigation (EMN)-guided preoperative localization, and uniportal video-assisted thoracic surgery (VATS) are recent innovations in minimally invasive thoracic surgery. This study aimed to explore the feasibility of applying nonintubated anesthesia in a "one-stage" localization and resection workflow.MethodsPatients who underwent EMN-guided preoperative percutaneous localization with indocyanine green (ICG) and uniportal VATS were included. Perioperative data were compared between patients receiving nonintubated anesthesia and those receiving general anesthesia with endotracheal intubation.ResultsForty-six patients with a total of 50 nodules were included in the study. Overall, finger palpation could be avoided in 94% of the nodules, whereas fluorescent green signals with a clear border on the pleural surface were noted in 91.3% (21 of 23) of nodules in the nonintubated group and 88.9% (24 of 27) of nodules in the intubated group. Intraoperatively, the nonintubated group had a lower median pH (7.33 [interquartile range (IQR), 7.28-7.40] vs 7.41 [IQR, 7.38-7.44]; P = .003), higher median arterial CO2 (45.5 [IQR, 41.1-58.7] mm Hg vs 38.4 [IQR, 35.3-40.6] mm Hg; P < .001), and lower arterial oxygen (322 [IQR, 211-433] mm Hg vs 426 [IQR, 355-471] mm Hg; P = .005) levels compared with the intubated group. The nonintubated group also had a shorter median registration time (2.0 [IQR, 1.0-3.0] minutes vs 3.0 [IQR, 2.0-8.0] minutes; P = .008) and total time in the operating room (150 [IQR, 130-175] minutes vs 170 [IQR, 135-203] minutes; P = .035), whereas no between-group differences were seen in localization and operative time. The duration of chest drainage, postoperative complications, pathologic diagnosis, and margins were similar in the 2 groups.ConclusionsNonintubated "one-stage" EMN-guided percutaneous ICG localization and uniportal VATS can be an option for selected patients undergoing treatment for small peripheral nodules.
