Minimally invasive approaches for en-bloc anatomical lung and chest wall resection

BACKGROUND: The aim of this study was to evaluate the feasibility of en-bloc anatomical lung and chest wall resection via minimally invasive surgery. METHODS: Between January 2013 and December 2021, a total of 22 patients (18 males, 4 females; mean age: 63±6.9 years; range, 48 to 78 years) who underwent anatomical lung and chest wall resection using minimally invasive surgery for non-small cell lung cancer were retrospectively analyzed. Demographic, clinical, intra- and postoperative data of the patients, recurrence, metastasis, mortality, and overall survival rates were recorded. RESULTS: The surgical technique was robot-assisted thoracic surgery in two, multiport video-assisted thoracoscopic surgery in 18, and uniport video-assisted thoracoscopic surgery in two patients. Upper lobectomy was performed in 17 (77.3%) patients, lower lobectomy in three (13.6%) patients, and upper lobe segmentectomy in two (9.1%) patients. Five different techniques were used for chest wall resection. Nine (40.9%) patients had one, eight (36.4%) patients had two, four (18.2%) patients had three, and one (4.5%) patient had four rib resections. Chest wall reconstruction was necessary for only one of the patients. The mean operation time was 114±36.8 min. Complete resection was achieved in all patients. Complications were observed in seven (31.8%) patients without mortality. The mean follow-up was 24.4±17.9 months. The five-year overall survival rate was 55.3%. CONCLUSION: Segmentectomy/lobectomy and chest wall resection with minimally invasive surgery are safe and feasible in patients with nonsmall cell lung cancer. In addition, the localization of the area where chest wall resection would be performed should be considered the most crucial criterion in selecting the ideal technique.
