Methods: The cost comparison analysis was based on the clinical pathway and drawn up by collecting the information available from the Thoracic Surgery Division medical team at Mantova Hospital. Direct resource consumption was derived from a previous randomized controlled trial including 40 patients. Use and maintenance of technology, equipment and operating room; administrative plus general costs; and 30-day use of postsurgery hospital resources were considered. The analysis was conducted from the hospital perspective. Results: On the average, a patient submitted to pulmonary lobectomy costs €9,744.29. This sum could vary from €9,027 (using ES) to €10,460 (using ST). The overall lower incidence (50% vs 95%, P=0.0001) and duration of air leakage (1.7 days vs 4.5 days, P=0.0001) in the ES group significantly affects the mean time of hospital stay (11.0 days vs 14.3 days) and costs. Cost saving in the ES group was also driven by the lower incidence of complications. The main key cost driver was staff employment (42%), then consumables (34%) and operating room costs (12%). Conclusion: There is an overall saving of around €1,432.90 when using ES patch for each pulmonary lobectomy. Among patients undergoing this surgical procedure, ES can significantly reduce air leakage incidence and duration, as well as decrease hospitalization rates. However, further multicenter research should be developed considering different clinical and managerial settings.

Backgrounds: Oligometastatic Non-Small Cell Lung Cancer (NSCLC) patients represent a category without a standard therapeutic approach. However, in selected oligometastatic NSCLC, radical surgery seems to offer a good prognosis. This retrospective study aimed to analyse the long-term outcomes of synchronous oligometastatic patients treated with curative intent and identify the factors associated with better results and the proposal of a risk stratification system for classifying the synchronous oligometastatic NSCLC., Methods: The medical records of patients from 18 centres with pathologically diagnosed synchronous oligometastatic NSCLC were retrospectively reviewed. The inclusion criteria were synchronous oligometastatic NSCLC, radical surgical treatment of the primary tumour with or without neoadjuvant/adjuvant therapy and radical treatment of all metastatic sites. The Kaplan - Meier method estimated survivals. A stratified backward stepwise Cox regression model was assessed for multivariable survival analyses., Results: 281 patients were included. The most common site of metastasis was the brain, in 50.89 % patients. Median overall survival was 40 months (95 % CI: 29-53). Age ≤65 years (HR = 1.02, 95 % CI: 1.00-1.05; p = 0.019), single metastasis (HR = 0.71, 95 % CI: 0.45-1.13; p = 0.15) and presence of contralateral lung metastases (HR = 0.30, 95 % CI: 0.15 - 0.62; p = 0.001) were associated with a good prognosis. The presence of pathological N2 metastases negatively affected survival (HR = 2.00, 95 % CI: 1.21-3.32; p = 0.0065). These prognostic factors were used to build a simple risk classification scheme., Conclusions: Treatment of selected synchronous oligometastatic NSCLC with curative purpose could be conducted safely and at acceptable 5-year survival levels, especially in younger patients with pN0 disease., (Copyright © 2021 Elsevier B.V.

The current coronavirus disease 2019 (COVID-19) pandemic has made us aware of the weaknesses and often the inadequacies of our current technologies and practices and has presented us with a huge challenge: to reorganize the way we work and sometimes even think, in order to ensure the safety of our patients. The Italian Society of Thoracic Surgery has launched various initiatives in response to the COVID-19 pandemic, aimed at facilitating the exchange of information, strategies and personal experiences between institutions. This article presents the results of a survey amongst all Italian thoracic surgery units accredited to SICT, with the aim of providing a glimpse of the current working conditions in these units, and an understanding of the impact of COVID-19 on their daily activities and patient care., (© The Author(s) 2020.

Background: Several gray areas and controversies exist concerning the management of pulmonary ground-glass opacities (GGOs), and there is a lack of consensus among clinicians on this topic. One of the main aims of the Italian Society of Thoracic Surgery is to promote education and research, so we decided to perform a survey on this topic to estimate current trends in practice in a large sample of thoracic surgeons., Methods: A total of 160 thoracic surgeons responded, namely, completed our questionnaire (response rate, 53%; 160 of 302). The survey was composed of 36 questions divided into six subsections: (1) demographic characteristics of the respondents; (2) terminology and taxonomy; (3) radiologic and radiometabolic evaluation; (4) diagnostic approach and indications for surgery; (5) surgical management; and (6) radiologic surveillance., Results: We observed some divergence of opinion regarding the definition of mixed GGOs, the role of 18F fluorodeoxyglucose positron emission tomography and computed tomography scans, indications for nonsurgical biopsy, intraoperative techniques for localizing GGOs, indications for surgery, extension of lung resection and lymph node dissection according to the radiologic scenario, use of intraoperative frozen section analysis, and radiologic surveillance of pure GGOs., Conclusions: This topic warrants more investigation in the future. An upcoming consensus conference of Italian Society of Thoracic Surgery experts (also open to experts in other specialties) could provide updated indications for GGO management based on the literature, expert opinions, and the results of the present survey., (Copyright © 2018 The Society of Thoracic Surgeons.

Alveolar air leaks, often resulting from lung tissue traumatization during dissection of fissures, still remain a challenging problem in lung surgery. Several tools and techniques have been used to reduce air leakage, but none was judged ideal. This prospective, randomized trial was designed to evaluate the feasibility, safety, and effectiveness of completion of fissures during pulmonary lobectomy by using a laser system. A standard stapler technique was used for comparison; the primary goal was to reach at least a comparable result. Forty-four patients were enrolled, 22 were treated with standard technique by using staplers (S) and 22 underwent laser (L) dissection. Randomization to one of the two groups was intraoperative after evaluating the presence of incomplete fissure (grade 3-4 following Craig's classification). A Thulium laser 2010 nm (Cyber TM, Quanta System, Italy) was used at power of 40 W. Outcome primary measures were the evaluation and duration of intra- and postoperative air leaks, the rate of complications, and the hospital stay. Air leaks (2.1 ± 4.2 vs 3.6 ± 7.2 days; p = 0.98) and chest tube duration (6.4 ± 4.2 vs 7.5 ± 6.3 days, p = 0.44) were lower in L compared with S group even if these were not statistically significant. Complications (36.4 vs 77.3 %; p = 0.006), hospital stay (6.9 ± 3.8 vs 9.9 ± 6.9 days; p = 0.03), hospitalization costs (5,650 vs 8,147 euros; p = 0.01), and procedure costs (77 % of difference; p < 0.0001) were significantly lower for L group, while operative time was longer (197 ± 34 vs 158 ± 41 min; p = 0.004). The use of laser dissection to prevent postoperative air leaks is effective and comparable with stapler technique. Aero-haemostatic laser properties (by sealing of small blood vessels and checking air leaks) allow a safe application during pulmonary lobectomy in interlobar fissure completion avoiding stapler use.

Objective: Alveolar air leaks are common after pulmonary resection, often prolonging hospitalization and increasing surgical morbidity and costs. Air leakages result from lung tissue traumatized by the dissection of fissures. This randomized and controlled trial evaluates 2 different surgical techniques for the completion of interlobar fissures during pulmonary lobectomy to establish which is superior in preventing air leakage., Methods: There were 20 patients in each of the 2 groups: Electrocautery was used for precision dissection and collagen patches were coated with human fibrinogen and thrombin (TachoSil, Nycomed, Vienna, Austria) for aerostasis in the electrocautery and sealant group (ES), and the approved routine surgical procedure with staplers was used in the stapler group (ST)., Results: Statistically significant reductions of air leakage were found in the ES group in the overall incidence of air leaks (50% vs 95%, P = .0001), duration of air leaks (1.7 days vs 4.5 days, P = .003), and procedure costs (425 euros vs 630.5 euros, P = .0001). There were no complications related to the use of the patches, and a significantly lower incidence of dead pleural space was observed in the ES group (5% vs 40%, P = .020)., Conclusion: The use of electrocautery dissection and collagen patches coated with human fibrinogen and thrombin (TachoSil, Nycomed, Vienna, Austria) for aerostasis to complete interlobar fissures seems to be safe and effective in reducing alveolar air leaks and procedure costs. Although this pilot study showed advantages in terms of hospitalization and cost benefits, further multicentric studies are required to clarify that these differences are statistically significant.

Background: Thoracic surgeons have limited experience with treating localized organizing pneumonia owing to its rare occurrence in routine clinical practice., Methods: We retrospectively investigated the clinicopathologic features of 21 patients with localized organizing pneumonia observed between 2001 and 2004., Results: There were 15 men and 6 women. Mean age was 63 years. Eight patients (38%) were symptomatic. Computed tomographic scan showed a single lesion in 17 patients (12 nodules and 5 masses) and bilateral lesions in 4. Wedge resection was performed in 16 patients and lobectomy in 5. There was no operative mortality. Follow-up was complete in all patients (range, 2 to 46 months; median, 20 months). Surgery was curative in 15 of 17 patients with a single lesion, and no recurrence was observed (p < 0.005). The remaining 2 patients with a single lesion (2 masses) had a local relapse with the appearance of nodular lesions in the residual parenchyma. Both these patients received steroids with resolution of the lesions. All 4 patients with bilateral lesions who underwent surgery for diagnostic purposes received steroids with improvement of the radiologic aspect in 3 and stabilization of the lesions in 1., Conclusions: Clinical and radiologic findings of localized organizing pneumonia are nonspecific, and this unusual entity is difficult to differentiate from a primary or metastatic tumor. Surgical resection allows both diagnosis and cure. However, considering the benignity of the lesion and the efficacy of steroids, major pulmonary resections should be avoided.

Objective: Persistent air leak is among the most common complications after pulmonary resection, leading to prolonged hospitalization and increased costs. At present there is not yet a consensus on their treatment., Methods: During a 7-year experience, 21 patients submitted to pulmonary resection were postoperatively treated with an autologous blood patch for persistent air leaks. Persistent air leaks were catalogued twice daily according to the classification previously reported by Cerfolio and associates. Chest radiographs showed a fixed pleural space deficit in 18 (86%) patients. A total of 50 to 150 mL of autologous blood was drawn from the patient and injected into the chest tube, which was removed 48 hours after cessation of the air leak., Results: We observed a 4% incidence of persistent air leaks after pulmonary resection in our series. Persistent air leaks were categorized as follows: 14% forced expiratory, 57% expiratory, 29% continuous, and 0% inspiratory. The mean duration of prolonged air leaks was 11 days after surgery. In 81% of the cases examined, a blood patch was only carried out once and gave successful results within 24 hours. In the remaining 19% of cases, the air leak ceased within 12 hours after the second procedure. Mean hospital stay was 15 days. In our experience this procedure had a 100% success rate., Conclusions: Pleurodesis with an autologous blood patch is well tolerated, safe, and inexpensive. This procedure is an effective technique for treatment of postoperative persistent air leaks, even in the presence of an associated fixed pleural space deficit.
