Project description:Pathology arising from the intrathoracic portion of the trachea (distal trachea), the carina and the main bronchi is usually neoplastic and is mainly treated with surgery. Resection of the intrathoracic portion of the trachea, the carina and the main bronchi for neoplastic lesions does not necessitate lung resection and is traditionally being conducted via open surgery. Video-assisted thoracic surgery (VATS) is witnessing an exponential growth and is the treatment of choice for early-stage non-small cell lung cancer (NSCLC). The experience accumulated over the past two decades along with the introduction of reliable and ergonomic technology, has led to the expansion of its indications. In this article we provide a detailed description of lung sparing distal tracheal, carinal and main bronchi resection for primary neoplasms of the airway, without involvement of the lung, with the uniportal video-assisted technique. The chest is entered through the fourth intercostal space, mid-axillary line. Dissection of the paratracheal space anteriorly, the tracheoesophageal groove posteriorly and the subcarinal space and division of the azygos arch are essential to mobilize the distal trachea and carina. Lateral dissection should be avoided beyond the points of division of the airway, as it may hinder the blood supply to the anastomosis. Any tension to the anastomosis should be relieved by release maneuvers. Ventilation is achieved through an endobronchial catheter, inserted into the left main bronchus through which a high-frequency jet ventilation catheter can be also inserted through it. The rationale of applying a minimally invasive technique for the conduction of tracheal and carinal resections, is to exploit its advantages, namely less pain, earlier mobilization and lower morbidity. Uniportal video-assisted resections of the distal trachea, carina and the main bronchi, are safe when conducted by experienced surgical and anesthetic teams.

Project description:BackgroundPreoperative three-dimensional (3D) lung reconstructions can reduce intraoperative blood loss, conversion rate, and operation duration. These 3D reconstructions are predominantly provided by commercial expensive products, hence we aimed to assess the usability and performance of preoperative 3D lung reconstructions created with open-source software.MethodsPatients were invited to participate in this prospective pilot study if they were planned for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy between January and February 2023. Participants were excluded if a two-dimensional (2D) late-arterial-phase computed tomography (CT) scan contained motion artifacts, another surgical procedure was performed, or the surgery was canceled. After informed consent was obtained, 3D lung reconstructions were constructed using open-source 3D Slicer software. The system usability score (SUS) questionnaire assessed the usability of these reconstructions, whilst performance was evaluated based on anatomical validity compared to prior 2D CT assessment as well as operative findings. Descriptive statistics were reported.ResultsThirteen patients were included, of whom one underwent a segmentectomy. Eighty-three percent of the 3D lung reconstructions scored above average (SUS >68). Compared to 2D CT scans, 38% of lung nodule segmental locations were detected more accurately through 3D lung reconstructions. Furthermore, 3D lung reconstructions revealed anatomical variations in 62%, which were not recognized on 2D CT scans, and provided surgeons with insights that would change the procedure and/or transection planes in 62%. One 3D lung reconstruction failed to demonstrate an intraoperative recognized segmental pulmonary artery (A6) branch.ConclusionsThree-dimensional lung reconstructions created with open-source software were usable and effective for uniportal VATS anatomical resections.Trial registrationClinicalTrials.gov/NCT06132607.

Project description:BackgroundEnhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control. We investigated the effect of non-steroidal analgesic drugs (NSAIDs) on pain control by comparing patient levels and opioid requirements after robotic pulmonary resections.MethodsWe retrospectively analyzed our prospectively maintained institutional database for elective, opioid-naïve robotic thoracoscopic pulmonary resections. All patients received postoperative NSAIDs unless contraindicated or at the discretion of the attending surgeons. Our original protocol (ERATS-V1) was modified to optimize opioid-sparing effect without affecting pain control (ERATS-V2). Demographics, operative outcomes, and postoperative opioid dispensed [morphine milligram equivalent (MME)] were collected.ResultsA total of 491 patients (147 ERATS-V1; 344 ERATS-V2) were included in this study. There was no difference in patient characteristics or operative outcomes between ERATS cohorts. Protocol optimization was associated with a 2- to 10-fold reduction of postoperative opioid use without compromising pain control. In ERATS-V1 cohort, there was no difference in pain levels and opioid requirements with NSAID usage. In ERATS-V2 cohort, while pain levels were similar, higher in-hospital opioid consumption was observed in no-NSAID subgroup {MME: 20.5 [interquartile range (IQR), 4.8-40.5] vs. 12.0 (IQR, 2.0-32.2), P=0.0096, schedule II: 14.2 (IQR, 3.0-36.4) vs. 6.8 (IQR, 1.4-24.0), P=0.012} as well as total postoperative schedule II opioid requirement [17.8 (IQR, 3.0-43.5) vs. 8.8 (IQR, 1.5-30), P=0.032].ConclusionsThe opioid-sparing effect of NSAIDs was observed only in optimized ERATS patients. Modifications of our pre-existing ERATS was associated with a significant reduction of opioid consumption without affecting pain levels. This revealed the role of NSAIDs in postoperative pain management otherwise masked by excessive opioids use.

Project description:BackgroundSince the conception of enhanced recovery after surgery protocols, tubeless strategies have become popular. Herein, we introduce a previously unreported alternative air-extraction strategy for patients who have undergone thoracoscopic wedge resection and explore its feasibility and safety.MethodsBetween January 2015 and June 2017, 264 consecutive patients underwent thoracoscopic wedge resection with different drainage strategies. Patients were divided according to the postoperative drainage strategies used: routine chest tube drainage (RT group), complete omission of chest tube drainage (OT group), and prophylactic air-extraction catheter insertion procedure (PC group). Using the propensity score matching method, clinical parameters and objective operative qualities were compared among the three groups.ResultsOptimal 1:1 matching was used to form pairs of RT (n =36) and PC (n =36) groups and balance baseline characteristics among the three groups. The incidence rates of pneumothorax were 5.6% (2/36), 9.8% (5/51), and 19.4% (7/36) in the RT, OT, and PC groups, respectively (P = 0.07). Chest tube reinsertion incidence for postoperative pneumothorax was 19.4% (1/7) in the PC group and 60% (3/5) in the OT group. Other postoperative complications were comparable among these groups.ConclusionsThe prophylactic air-extraction strategy may be an alternative procedure for selected patients. Remedial air extraction may reduce the occurrence of chest tube reinsertion for pneumothorax patients, but further investigation is required.

Project description:BackgroundLung cancer patients with chronic obstructive pulmonary disease (COPD) are considered a high-risk population to receive radical surgical treatment due to the high incidence of cardiopulmonary complications. The aim of this study was to evaluate the clinical factors associated with postoperative complications in primary lung cancer patients with moderate to extremely severe grades of COPD.MethodsFrom December 2015 to June 2020, 138 patients with moderate to extremely severe COPD who underwent video-assisted thoracoscopic surgery (VATS) lung cancer resection (lobectomy or sublobar resection) were retrospectively reviewed. Patients' postoperative complications were collected from clinical records. Clinical factors (such as COPD severity or surgical approaches, etc.) were evaluated to investigate the association with postoperative complications.ResultsOf the 138 patients included in the study, the mean age was 67 (63-74) years, the mean preoperative forced expiratory volume in one second (FEV1) was 1.33±0.39 L, the mean FEV1% was 51.23% (41.43-60.00%). 33% patients (46/138) had postoperative complications, and no mortality occurred. Univariate analysis revealed that incidence of overall complications (OCs) and respiratory complications (RCs) was markedly higher in extremely severe COPD patients compared to moderate (OCs, P=0.033; RCs, P=0.050) and severe (OCs, P=0.015; RCs, P=0.008) COPD patients, respectively. Multivariate analysis showed that COPD grade was an independent risk factor of RCs (P=0.024). Furthermore, the grades of COPD (moderate, P=0.029; severe, P=0.028; extremely severe, P=0.019) and the surgical procedure (lobectomy or sublobar resection, P=0.043) were independent risk factors for atelectasis, which was the most common postoperative complication.ConclusionsThe aggravation of COPD was accompanied by an increase in the incidence of respiratory system complications postoperatively, especially atelectasis. For patients with moderate to extremely severe grades of COPD, careful perioperative evaluation should be performed to identify the indicators that influence the surgical choice between lobectomy and sublobar resection.

Project description:Abstract The main focus of this study was to compare the predictive value of coagulation, fibrinolysis, thromboelastography, stress response, and immune function in predicting the incidence of deep venous thrombosis (DVT) in lung cancer (LC) patients undergoing thoracoscopic LC resection vs thoracotomy LC resection. To do that, a prospective, single-center, case-control study involving 460 LC patients was conducted. The risk indicators affecting patients with DVT after LC resection in the testing cohort were determined using logistic regression and receiver operator characteristic (ROC) analyses. One validation cohort was used to assess the risk prediction models. DVT incidence was higher in the thoracoscopic group (18.7%) than in the thoracotomy group (11.2%) in the testing cohort (χ2 = 4.116, P = 0.042). The final model to predict the incidence of DVT after thoracoscopic LC excision (1 day after surgery) was as follows: Logit(P) = 9.378 – 0.061(R-value) – 0.109(K value) + 0.374(α angle) + 0.403(MA) + 0.298(FIB) + 0.406(D-D) + 0.190(MDA) − 0.097(CD4+/CD8+). For thoracotomy LC resection, the final model (3 days after operation) was: Logit(P) = –2.463 − 0.026(R-value) − 0.143(K value) + 0.402(α angle) + 0.198(D-D) + 0.237(MDA) + 0.409(SOD). In the validation cohort, this risk prediction model continued to demonstrate good predictive performance. As a result, the predictive accuracy of postoperative DVT in patients who underwent thoracoscopic LC resection and thoracotomy LC resection was improved by risk prediction models. Graphical abstract

Project description:Long-segment tracheal resection is technically challenging due to its high tension during reconstruction. Therefore, tracheal release maneuvers, including pulmonary hilar release and pericardial dissection, were required to reduce the anastomotic tension. Traditional hilar release is performed via thoracotomy; however, this approach is invasive. We report a case of bilateral hilar and pericardial release via a video-assisted thoracoscopic surgery (VATS) approach in resecting a long segment tracheal adenoid cystic carcinoma that spanned 50% of the trachea. The bilateral hilar and pericardial releases were performed under general anesthesia through biportal VATS, which contributed to a total of 2.5 cm of additional mobility to the trachea, and the infrahyoid release was then performed through a cervical collar incision. The tumor-involved tracheal segments were removed via median sternotomy, totaling 6.0 cm in length, and the remaining trachea could be successfully reconstructed with a tension-free anastomosis. The total operative duration was 4.5 hours. The patient suffered a transient swallowing dysfunction during the postoperative course, with a good luminal patency in the trachea after 1 month postoperatively. Therefore, bilateral hilar release via VATS can be considered to be a less invasive, avoiding the potential complications related to a thoracotomy, but similarly effective release maneuver for long-segment tracheal resections.

Project description:Chemoradiotherapy followed by surgical resection (trimodality therapy) is a guideline recommended treatment for sulcus superior tumors (SST). By definition, SSTs invade the chest wall and therefore require en-bloc chest wall resection with the upper lung lobe or segments. The addition of a chest wall resection, potentially results in higher morbidity and mortality rates when compared to standard anatomical pulmonary resection. This, together with their anatomical location in the thoracic outlet, and varying grades of fibrosis and adhesions resulting from induction chemoradiotherapy in the operation field, make surgery challenging. Depending on the exact location of the tumor and extent to which it invades the surrounding structures, the preferred surgical approach may vary, e.g., anterior, posterolateral, hemi-clamshell, or combined approach; all with their own potential advantages and morbidities. Careful patient selection, adequate staging and discussion in a multidisciplinary tumor board in a center experienced in complex thoracic oncology leads to the best long-term survival outcomes with the least morbidity and mortality. Enhanced recovery guidelines are now available for thoracic surgery, promoting faster recovery and helping to minimize complications and morbidity, including infections and thoracotomy pain. Although minimally invasive surgery can enhance recovery and reduce chest wall morbidity, and is in widespread use in thoracic oncology, its use for SST has been limited. However, this is an evolving area and hybrid surgical approaches (including use of the robot) are being reported. Chest wall reconstruction is rarely necessary, but if so, the prosthetic materials are preferably radiolucent/non-scattering, rigid enough while still being somewhat flexible, and inert, providing structural support, allowing chest wall movement, and closing defects, while inciting a limited inflammatory response. New techniques such as 3D image reconstructions/volume rendering, 3D-printing, and virtual reality modules may help pre-operative planning and informed patient consent.
