Background: Non-intubated thoracoscopic surgery with spontaneous breathing is rarely utilized, but may have several advantages over standard intubation, especially in those with significant cardiopulmonary comorbidities. In this study we evaluate the safety, feasibility, and 3-year survival of thoracoscopic surgery without endotracheal intubation for oncologic and non-oncologic indications.
Methods: All consecutive patients [2018-2022] selected for lung resection or other pleural space intervention under local anesthesia and sedation were compared to a cohort undergoing elective thoracoscopic procedures with endotracheal intubation. A propensity-score matched cohort was used to compare perioperative outcomes and 3-year overall survival.
Results: A total of 72 patients underwent thoracoscopic surgery without intubation compared to 1,741 who were intubated. Non-intubated procedures included 19 lobectomies (26.4%), 9 segmentectomies (12.5%), 25 wedge resections (34.7%), and 19 pleural or mediastinal resections (26.4%). Non-intubated patients had a lower average body mass index (BMI; 24.6 27.1 kg/m, P<0.001) and a higher comorbidity burden. Primary lung cancer was the indication in 30 (41.7%) non-intubated patients. The non-intubated cohort had no operative or 30-day mortality. After propensity-score matching, there was no significant difference in pre-operative factors. In propensity-score matched analysis, non-intubated patients had shorter median total operating room time (109 159 min, P<0.001) and procedure time (69 119 min, P<0.001). Peri-operative morbidity was rare and did not differ between intubated and non-intubated patients. There was no significant difference in 3-year survival associated with non-intubation in the propensity-score matched cohorts (95% 89%, P=0.10) or in a Cox proportional hazard model [hazard ratio (HR), 1.15; 95% confidence interval (CI): 0.36-3.67; P=0.81].
Conclusions: Non-intubated thoracoscopic surgery is safe and feasible in carefully selected patients for both benign and oncologic indications.

We demonstrate that performing anatomical pulmonary resection by video-assisted thoracoscopic surgery without staplers or energy devices is feasible. This technique is an alternative for surgeons with limited access to expensive technologies.

: Video-assisted thoracoscopic surgery (VATS) is associated with less postoperative pain than traditional open thoracotomy. However, trocar and chest tube placement may damage the intercostal nerves, causing significant discomfort. An ultrasound-guided serratus anterior plane block (SAPB) is a promising mode of pain management; this reduces the need for opioids and the associated side-effects.

Background: Neuroendocrine tumors of the thymus (NETT) are rare and malignant tumors that arise in the anterior mediastinum. These tumors can exhibit aggressive behavior and may involve surrounding critical structures, such as the superior vena cava. This case contributes to the literature by presenting a recurrent thymic carcinoma with invasion of major blood vessels, including the superior vena cava, and the complexities involved in its surgical management.

Background: Video-assisted thoracoscopic surgery (VATS) is widely used in lung cancer surgery, as this technique causes less pain and faster recovery than open thoracotomy. However, significant postoperative pain persists in a number of patients, often leading to increased opioid use and opioid-related adverse events in addition to prolonged admission times. Perioperatively administered glucocorticoids have been demonstrated effective in reducing pain after other types of surgeries, but the effect in VATS remains unclear.

. The optimal surgical approach for thymoma resection is still an object of debate. The increasing experience in robotic-assisted thoracic surgery (RATS) has led to the progressive affirmation of this technique as a valid alternative to Sternotomy, Thoracotomy and Video-Assisted Thoracic Surgery (VATS) in this setting.
