RESUMO
BACKGROUND: Analyzing the risk factors that predict readmissions can potentially lead to more individualized patient care. The 11-factor modified frailty index is a valuable tool for predicting postoperative outcomes following surgery. The objective of this study is to determine whether the frailty index can effectively predict readmissions within 90 days after lung resection surgery in cancer patients within a single health care institution. METHODS: Patients who underwent elective pulmonary resection for nonsmall cell lung cancer (NSCLC) between January 2012 and December 2020 were selected from the hospital's database. Patients who were readmitted after surgery were compared to those who were not, based on their data. Propensity score matching was employed to enhance sample homogeneity, and further analyses were conducted on this newly balanced sample. RESULTS: A total of 439 patients, with an age range of 68 to 77 and a mean age of 72, were identified. Among them, 55 patients (12.5%) experienced unplanned readmissions within 90 days, with an average hospital stay of 29.4 days. Respiratory failure, pneumonia, and cardiac issues accounted for approximately 67% of these readmissions. After propensity score matching, it was evident that frail patients had a significantly higher risk of readmission. Additionally, frail patients had a higher incidence of postoperative complications and exhibited poorer survival outcomes with statistical significance. CONCLUSION: The 11-item modified frailty index is a reliable predictor of readmissions following pulmonary resection in NSCLC patients. Furthermore, it is significantly associated with both survival and postoperative complications.
RESUMO
Sternal wound complications following cardiac surgery, including sternal dehiscence, mediastinitis, and osteomyelitis, pose significant challenges in terms of management and patient outcomes. We present a case report highlighting the complex management of a patient who underwent open heart surgery for severe aortic valve stenosis, followed by sternal wound dehiscence and sternum osteomyelitis due to extended spectrum beta lactamase (ESBL) producing Klebsiella aerogenes. A multiple myeloma diagnosis was also suspected at the positron emission tomography (PET) scan and confirmed with bone marrow biopsy. Multidisciplinary evaluation of the case led to a comprehensive treatment plan. To control the sternal osteomyelitis, total sternectomy was performed followed by immediate reconstruction with a bone (tibia) graft from the tissue bank and fixation with the minimal hardware possible. A microsurgical latissimus dorsi free flap was required to reconstruct the soft tissue defect. After 6 weeks of antibiotic treatment with ertapenem and fosfomycin based on a culture of intraoperative material, no clinical, imaging, or laboratory signs of infection were seen. Multiple myeloma treatment was then started. At 1 year of follow up, no recurrence of infection occurred, and the reconstruction was stable and closed. Multiple myeloma is under chronic treatment with novel agent combination, with an excellent haematological response.
RESUMO
BACKGROUND: Surgery for thymic cancers is considered the key of curative treatment. Preoperative patients' characteristics and intraoperative features might influence postoperative outcome. We aim to verify short-term outcomes and possible risk factors for complications after thymectomy. METHODS: We retrospectively investigated patients undergoing surgery for thymoma or thymic carcinoma in the period between January 1, 2008, and December 31, 2021, in our department. Preoperative features, surgical technique (open, bilateral VATS, RATS), intraoperative characteristics and incidence of postoperative complications (PC) were analyzed. RESULTS: We included in the study 138 patients. Open surgery was performed in 76 patients (55.1%), in 36 VATS (26.1%) and in 26 RATS (36.1%). Resection of one or more adjacent organs due to neoplastic infiltration was required in 25 patients. PC appeared in 25 patients (52% Clavien-Dindo grade I, 12% grade IVa). Open surgery had a higher incidence of PC (p < 0.001), longer postoperative in-hospital stay (p = 0.045) and larger neoplasm (p = 0.006). PC were significant related to pulmonary resection (p = 0.006), phrenic nerve resection (p = 0.029), resection of more than one organ (p = 0.009) and open surgery (p = 0.001), but only extended surgery of more organs was confirmed as independent prognostic factor for PC (p = 0.0013). Patients with preoperative myasthenia symptoms have a trend toward stage IVa complications (p = 0.065). No differences were observed between outcomes of VATS and RATS. CONCLUSIONS: Extended resections are related to a higher incidence of PC, while VATS and RATS guarantee a lower incidence of PC and shorter postoperative stay even in patients that require extended resections. Symptomatic myasthenia patients might have a higher risk toward more severe complications.

The aim of this study was to assess the impact of BMI on perioperative outcomes in patients undergoing VATS lobectomy or segmentectomy. Data from 5088 patients undergoing VATS lobectomy or segmentectomy, included in the VATS Group Italian Registry, were collected. BMI (kg/m2) was categorized according to the WHO classes: underweight, normal, overweight, obese. The effects of BMI on outcomes (complications, 30-days mortality, DFS and OS) were evaluated with a linear regression model, and with a logistic regression model for binary endpoints. In overweight and obese patients, operative time increased with BMI value. Operating room time increased by 5.54 minutes (S.E. = 1.57) in overweight patients, and 33.12 minutes (S.E. = 10.26) in obese patients (P < 0.001). Compared to the other BMI classes, overweight patients were at the lowest risk of pulmonary, acute cardiac, surgical, major, and overall postoperative complications. In the overweight range, a BMI increase from 25 to 29.9 did not significantly affect the length of stay, nor the risk of any complications, except for renal complications (OR: 1.55; 95% CI: 1.07-2.24; P = 0.03), and it reduced the risk of prolonged air leak (OR: 0.8; 95% CI: 0.71-0.90; P < 0.001). 30-days mortality is higher in the underweight group compared to the others. We did not find any significant difference in DFS and OS. According to our results, obesity increases operating room time for VATS major lung resection. Overweight patients are at the lowest risk of pulmonary, acute cardiac, surgical, major, and overall postoperative complications following VATS resections. The risk of most postoperative complications progressively increases as the BMI deviates from the point at the lowest risk, towards both extremes of BMI values. Thirty days mortality is higher in the underweight group, with no differences in DFS and OS.

Mesothelioma is an aggressive disease arising from parietal pleura. Surgery is a valuable option in the frame of a multimodality treatment. Several surgical approaches have been standardized with the aim of a macroscopic complete resection; these often require homolateral diaphragm and pericardial resection and reconstruction. Extrapleural pneumonectomy (EPP) and extended pleurectomy decortication (EPD) have been recognized as radical surgical procedures. Nevertheless, both operations are technically challenging and associated with a significant rate of peri-operative morbidity and non-negligible mortality. The diaphragmatic and pericardial reconstruction technique is mandatory to avoid respiratory impairment and to reduce post-operative complications like gastric and cardiac herniation. Moreover, in the case of localized chest wall recurrence, surgery might be considered a valuable therapeutical option for highly selected and fit patients. All the technical aspects of the resection and reconstruction of the diaphragm, pericardium, and chest wall are described as well as the possible use of new minimally invasive techniques. In addition, the choice of different prosthetic materials, considering the most recent innovations in the field, are discussed.
RESUMO
BACKGROUND: Sternal transplant using cadaveric allograft (STCA) is a complex and rarely performed surgical procedure usually applied for massive bone tissue loss, sternotomy complications, or neoplastic resections. Although radiological imaging and especially computed tomography (CT) is routinely applied for the post-surgical assessment, up to now, a standardized approach evaluating the outcome of STCAs is missing. Therefore, aim of this study was to qualitatively and quantitatively evaluate, by CT, bone healing after STCA. METHODS: The first and the last available postsurgical CT of patients who underwent STCA in two tertiary centers between 2009 and 2017 were collected. Standardized regions of interest were applied on the cancellous bone along the transplanted sternum, and, as reference, on the fourth thoracic vertebra, at both time points, collecting the density values. The areas nearby the fixation devices were assessed by a four-points qualitative score. To evaluate the mineralization, the analysis of the variance (ANOVA) with post-hoc Bonferroni correction was applied for the quantitative measurements while the Wilcoxon test was used for the qualitative score (P<0.05). To evaluate the intra-rater reliability of the qualitative and the quantitative analyses, the same rater repeated the measurements after two months and the Cohen's kappa (k) and the intraclass correlation coefficient (ICC) were computed. RESULTS: Fourteen patients (11 females, 61±12.8 years) were examined. The first control CTs were performed 32±40.26 days after the STCA and the last CT were acquired after 729±745 days. The quantitative and the qualitative score significantly increased between the two intervals (P<0.05, each). The density of the transplanted sternum was lower than that of the vertebral reference at the first CT (P=0.006) while no differences occurred at the last control (P=0.361). The assessments showed high intra-rater reliability and agreement (ICC ≥0.890, k≥0.906). CONCLUSIONS: The hereby-proposed qualitative and quantitative methods demonstrated to be good tools for assessing bone healing after STCA.
RESUMO
Removal of foreign bodies from the upper gastrointestinal tract, though a common occurrence, can be technically challenging and risky. We report the case of a young man that, after eating a pizza cooked in a wood-burning oven, reported a sense of foreign body. Though the first evaluation by fiberoptic laryngoscopy found no foreign body, after a few weeks, the patient was readmitted from the ER for worsening symptoms and fever. A CT scan showed a metallic mediastinal foreign body inside a large fluid collection. After multidisciplinary evaluation, an endoscopic removal was attempted by accessing the mediastinal collection through EUS-guided positioning of a Hot Axios™ stent. The cavity was drained by naso-esophageal suction. The foreign body was a fragment of the brush used to clean the oven. The patient is now doing well after 7 months.

BACKGROUND: Sternal resection and reconstruction with cryopreserved allografts provides a safe alternative to traditional methods of anterior chest wall reconstruction. Despite favorable results, successful integration of the graft sternum has never been demonstrated owing to the invasiveness of bone biopsy. We describe our experience of using 18F-sodium fluoride positron emission tomography/computed tomography scans as a noninvasive method of evaluating graft integration. METHODS: Seven patients underwent surgery and radiologic follow-up. Surgical indications were sternal metastases (n = 5) and sternal dehiscence (n = 2). Sternal reconstruction was performed using a cryopreserved cadaveric sternal allograft fixed in place with titanium plates and screws. Follow-up with 18F-sodium fluoride positron emission tomography/computed tomography scans was performed at 1 and 2 years after surgery. RESULTS: Three patients underwent total sternectomy. Two underwent partial upper sternectomy involving the manubrium, clavicle (1 patient only), and upper sternal body; and 2 had partial sternectomy of the sternal body and xiphoid process. Focal tracer accumulation occurred at the junctions between native bone and graft bone. The median maximum standardized uptake value at 1 year was 16.8 (range, 11.2 to 37.9; interquartile range, 13.6 to 19.4), and at 2 years it was 10.8 (range, 6.1 to 30.2; interquartile range, 8.9 to 15.1). In 6 cases accumulation was lower at the second scan, whereas in 1 patient the accumulation was higher at the second scan. CONCLUSIONS: Sternal reconstruction with cryopreserved allograft is safe and well tolerated. The 18F-sodium fluoride positron emission tomography/computed tomography scans are a useful and promising noninvasive method of demonstrating the metabolic activity of the graft and its incorporation into the host skeleton during follow-up.

BACKGROUND: Reconstruction of the anterior chest wall defect after sternectomy is a challenge for cardiothoracic surgeons. In 2010, the Padua group published the first case of cadaveric sternum transplantation after sternectomy. This multicenter study reports the clinical indications and early and long-term results of sternal chondral allograft transplantation. METHODS: This is a retrospective multicenter study from 7 academic centers. We collected demographic data, surgical indications, technical details, and early postoperative results. The complications, long-term stability, and tolerance of the allografts were also analyzed. RESULTS: Between January 2008 and December 2019, 58 patients underwent sternectomy followed by reconstruction using cadaveric-cryopreserved sternochondral allografts. Thirty-two patients were male, median age 63.5 years (interquartile range, 50-72 years). Indications for sternectomy were secondary sternal tumors (n = 13), primary sternal tumors (n = 15), and nonneoplastic disease (n = 30). Thirty patients underwent total sternectomy, 16 lower-body sternectomy, and 12 upper-body manubrium resection. The 30-day mortality was 5%; overall morbidity was 31%. Six early reoperations were necessary because of bleeding (n = 1), titanium plate dislocation (n = 1), and resuture of the skin in the lower part of the incision (n = 4). Overall, 5-year survival was 74%. In all the survived patients, the reconstructions were stable and free from mechanical or infective complications. CONCLUSIONS: The main indications for sternal allograft implantation were complex poststernotomy dehiscence followed by primary or secondary tumor involvement of the sternum. The collected results demonstrate that sternochondral allograft transplantation is a safe and effective method in reconstructing the anterior chest wall after sternectomy. Further studies to demonstrate the integration of the bone grafts into the patients' sternal wall will be made.

BACKGROUND: Lung transplantation is nowadays the standard therapy for certain well-defined chronic end-stage lung diseases, even in patients on mechanical ventilation or extracorporeal life support. While these latter techniques have been used worldwide as bridging options to lung transplantation for listed patients, they are not commonly used in previously healthy patients developing acute not-reversible lung failure. METHODS: We will discuss two patients without any relevant medical history developing acute lung failure evolving to irreversible acute fibrinous and organising pneumonia (AFOP), thus listed for urgent lung transplantation. RESULTS: The patients recovered well, and both are still alive. CONCLUSIONS: In the absence of clear guidelines, our approach showed, in these patients, the possible benefits of lung transplantation regarding survival in AFOP.

BACKGROUND: Many new surgical techniques and materials have been introduced in the last decade for chest wall reconstruction or stabilization with the purpose of improving the incorporation, maintaining chest wall stability with reduction of infections. However, none of them are yet considered a gold standard procedure. The aim of this work is to evaluate the initial experience using a new titanium mesh for chest wall reconstruction in four Italian Thoracic Surgery Departments. METHODS: A review was performed of all patients undergoing chest wall reconstruction using a new titanium mesh between January 2014 and September 2018. Surgical indications, the location and size of the chest wall defect, intraoperative variables and postoperative complications were analyzed. RESULTS: A total of 26 consecutive patients were included. The most common indications for surgery were primary or secondary chest wall tumors (38%) followed by lung cancer invading chest wall (31%). The most common localization of chest wall defect was anterolateral (46%). Sternal reconstruction was required in 3 patients (12%). The average size of the defect was 9.3×7.8 cm. The median number of resected ribs was 3.6. No perioperative deaths occurred. Mean hospital stay was 11.9 days. Overall morbidity was 19%. One failure of reconstruction (4%) was reported during follow up. CONCLUSIONS: In our early clinical experience chest wall reconstruction using titanium mesh can be performed as a safe and effective surgical procedure. This mesh has excellent biomechanical characteristics between rigid and malleable materials, it's easy to trim and fix for optimal adaptation without necessity of dedicated instruments. The early and mid-term results are satisfactory with low incidence of complications related to the titanium mesh implant.
RESUMO
Rationale: The diagnostic concordance between transbronchial lung cryobiopsy (TBLC)-versus surgical lung biopsy (SLB) as the current gold standard-in interstitial lung disease (ILD) cases requiring histology remains controversial. Objectives: To assess diagnostic concordance between TBLC and SLB sequentially performed in the same patients, the diagnostic yield of both techniques, and subsequent changes in multidisciplinary assessment (MDA) decisions. Methods: A two-center prospective study included patients with ILD with a nondefinite usual interstitial pneumonia pattern (on high-resolution computed tomography scan) confirmed at a first MDA. Patients underwent TBLC immediately followed by video-assisted thoracoscopy for SLB at the same anatomical locations. After open reading of both sample types by local pathologists and final diagnosis at a second MDA (MDA2), anonymized TBLC and SLB slides were blindly assessed by an external expert pathologist (T.V.C.). Kappa-concordance coefficients and percentage agreement were computed for: TBLC versus SLB, MDA2 versus TBLC, MDA2 versus SLB, and blinded pathology versus routine pathology. Measurements and Main Results: Twenty-one patients were included. The median TBLC biopsy size (longest axis) was 7 mm (interquartile range, 5-8 mm). SLB biopsy sizes averaged 46.1 ± 13.8 mm. Concordance coefficients and percentage agreement were: TBLC versus SLB: κ = 0.22 (95% confidence interval [CI], 0.01-0.44), percentage agreement = 38% (95% CI, 18-62%); MDA2 versus TBLC: κ = 0.31 (95% CI, 0.06-0.56), percentage agreement = 48% (95% CI, 26-70)%; MDA2 versus SLB: κ = 0.51 (95% CI, 0.27-0.75), percentage agreement = 62% (95% CI, 38-82%); two pneumothoraces (9.5%) were recorded during TBLC. TBLC would have led to a different treatment if SLB was not performed in 11 of 21 (52%) of cases. Conclusions: Pathological results from TBLC and SLB were poorly concordant in the assessment of ILD. SLBs were more frequently concordant with the final diagnosis retained at MDA.

OBJECTIVES: The aim of this study was to evaluate a new self-expanding tract sealant device, designed to prevent pneumothorax after computed tomography (CT)-guided lung biopsy, as an intraoperative marker for small pulmonary nodules or ground-glass opacities during minimally invasive thoracic surgery. METHODS: Three patients with pulmonary nodules underwent CT-guided biopsies in our radiology department. During the same procedure, using a 19-gauge coaxial needle, a self-expanding tract sealant device was positioned in the lung nodule to be used not only for the prevention of pneumothorax but also as an intraoperative marker. A few days later, conventional thoracoscopic surgery was scheduled. A visual examination was performed. The site of the deployment of the BioSentry device was determined by checking for the proximal end of it beyond the visceral pleura. Thoracoscopic wedge resections using endoscopic staplers were performed to confirm histological characteristics, surgical margins and correct placement of the plug. RESULTS: Three consecutive patients underwent CT-guided placement of this self-expanding tract sealant device (BioSentry) before surgery, without complications. The thoracoscopic resection was performed with success. The plug was easy to visualize with the scope, and all removed nodules had surgical free margins and the plug was correctly positioned in all patients. CONCLUSIONS: The self-expanding tract sealant device was created for the reduction of pneumothorax and chest tube placement rates after percutaneous lung biopsy. We used it for the first time for intraoperative localization of peripheral small solid nodules or ground-glass opacities with good results.

BACKGROUND: Acute post-operative pain following thoracic surgery procedures is still an unresolved problem despite the introduction of minimally invasive procedures such as video assisted surgery. Until now it is never investigated if different surgical instruments could influence post-operative pain. The aim of our study is to investigate the role of different type of trocar on post-operative pain in minimally invasive thoracic surgery. METHODS: This was a prospective randomized single center study. We identified 53 patients randomized into three groups underwent single port thoracoscopy for malignant pleural effusion with drainage of the fluid and talc poudrage. The three groups differ for the trocar type, rigid, flexible and wound protector. RESULTS: We compared the postoperative pain between the three groups in which there was no statistical difference. Rigid trocar seems to give a more stable level of pain during the days, flexible trocar gains more pain in the first few hours, however the pain at discharge decreases significantly, reaching the similar values, in all the three groups. The association between pain at discharge and operative time or days of drainage was analyzed by means of linear regression, no statistically significant difference was found. CONCLUSIONS: Our study showed that different type of trocars during video assisted thoracic surgery (VATS) produces similar level of acute postoperative pain. In future, further randomized study with a great number of patients enrolled needs to confirm our results.
RESUMO
Isolated unilateral pulmonary vein atresia (UPVA) is a rare congenital malformation and the management remains controversial. In adults, pneumonectomy is the treatment of choice when significant hemoptysis becomes life-threatening. We report a case of a 28-year-old male with isolated unilateral right atresia of the pulmonary vein who had life-threatening hemoptysis treated with bronchial arteries embolization followed by successful right pneumonectomy.
RESUMO
Cystic lesions of the pericardium are a rare entity. Generally, they are congenital and located in the cardiophrenic angle. The right paratracheal location is unusual and differential diagnosis in particular with bronchogenic cyst is difficult even when using magnetic resonance imaging (MRI). The surgical indication exists in case of symptomatic patients or huge mass with compression of nearby structures. Different surgical approaches have been reported in literature to treat mediastinal cysts. We report a case of uniportal thoracoscopic removal of an unusual located right paratracheal pericardial cyst.
RESUMO
Pulmonary sequestration (PS) is a rare congenital malformation of the respiratory tract. Two main variants are described, the intralobar and the extralobar PS. Clinical manifestations vary from accidental findings to life threatening complications. Surgical resection is the definitive and indicated treatment of PS. The operation could be performed through an open thoracotomy or video-assisted thoracic surgery approach. We report the management of two patients with diagnosis of extralobar PS in the first case and intralobar PS in the second case. Both patients underwent uniportal video-assisted thoracic surgery resection of PS with success. In our experience, we confirm that uniportal video-assisted thoracic surgery is a safe and feasible approach for extralobar and intralobar PS.
RESUMO
Primary spontaneous pneumothorax has been defined as the disease of the 'young and healthy'. There are multiple possible therapies and in recent years, surgery has evolved towards the use of the uniportal thoracoscopic approach. The objective of our study is to describe and present an innovative approach to access to the thoracic cavity in patients with spontaneous pneumothorax. The surgery was performed using a single access of 20 mm at the level of the 8th intercostal space. For the isolation and suspension of any dystrophic area, we use a 'loop' of non-absorbable braided suture inserted through the IV intercostal space and successive wedge resection using an endoscopic 10 mm mechanical stapler. Using this access, we were able to visualize and dissect the pulmonary ligament and perform complete pleural abrasion. We had no complications. The operative time was 60 min, the chest tube was removed the 2th postoperative day and the patient was discharged the day after. The operation we propose permits the reduction of the dimension of the access to the thoracic cavity. We were able to resect blebs without problems, the recovery was excellent and no complications related to the procedure were reported.
RESUMO
BACKGROUND: Surgical excision with wide margins, prevention of respiratory impairment, and protection of surrounding organs are primary goals in resection and reconstruction of the chest wall. We describe our experience of the use of cadaveric cryopreserved sternal allograft. METHODS: Eighteen patients underwent surgery. Indications for sternectomy were sternal metastases (n = 9), primary chondrosarcoma (n = 4), sternal dehiscence (n = 2), soft tissue sarcoma (n = 1), malignant solitary fibrous tumor (n = 1), and direct involvement of thymic carcinoma (n = 1). The defect was reconstructed using a cadaveric sternal allograft harvested aseptically, treated with antibiotic solution, and cryopreserved (-80°C). The graft was tailored to fit the defect and fixed in place with titanium plates and screws. RESULTS: Four patients underwent a total sternectomy, 8 a partial lower sternectomy, and 6 a partial upper sternectomy. In 14 patients, muscle flaps were positioned to cover the graft. During the postoperative course, 1 patient died of pulmonary embolism, 1 had systemic Candida infection, and 1 had surgical revision for bleeding at the site of muscle flap. One patient required removal of a screw on the clavicle 4 months after operation because of partial dislocation. At a median follow-up of 36 months, neither infection nor rejection of the graft occurred; 13 patients are alive without disease, and 4 patients had died. None had local tumor relapse. CONCLUSIONS: Sternal replacement with cadaveric allograft is safe and effective, providing optimal stability of the chest wall and protection of the surrounding organs, even after extensive chest wall resections. The allograft was biologically well tolerated, allowing a perfect integration into the host.

We standardised a Ventilation Mechanical Test (VMT) after video-assisted thoracoscopic surgery (VATS) lobectomy that classifies intraoperative alveolar air leaks (IOAALs) in mild, moderate and severe. We assumed that mild IOAALs (<100 mL/min) are self-limiting, whereas severe IOAALs (>400 mL/min) must be treated. An IOAAL between 100 and 400 mL/min was defined moderate and constituted the study population of a prospective multicentre randomised trial on the use of a polymeric biodegradable sealant (ProgelTM Pleural Air Leak Sealant, Bard Davol, USA) in case of moderate IOAAL compared with no treatment. We assumed that the standardised VMT allows to accurately selected patients needing treatment, thus limiting unnecessary sealant use. We analysed data of the randomised trial to assess the cost-effectiveness of Progel treatment in VMT selected patients. This is a multicenter randomised controlled trial. Patients with moderate IOAAL were randomised to Progel (group A) or "no treatment" (group B).The primary efficacy endpoint of the study was the postoperative duration of air leakage. The secondary outcome measures included: mean time to chest drain removal, mean length of hospitalisation, the percentage of postoperative complications occurring within two months, and cost of treatment. Between January 2015 and January 2017, 255 VATS lobectomies were performed in 4 centres, 55 met the inclusion criteria, and they were randomly assigned to 2 different groups (28 in the Progel and 27 in the control group). The mean air leakage duration was statistically different between the two groups: in the group A was 1.60 vs. 5.04 days in group B (P<0.001). The average duration of chest drainage was statistically shorter in group A than in the control group (4.1 vs. 6.74 days; P=0.008). The mean time to hospital discharge was also statistically shorter in group A than in group B (5.75 vs. 7.85 days, P=0.026). In the Progel group, a statistically significant reduction of hospitalisation costs compared with the control group was observed (Progel group =12,905£, Control group =39,690£; P<0.001). Our standardised VMT helps in reducing the length of hospital stay after VATS lobectomy because in case of IOAALs between 100 and 400 mL/min the use of ProgelTM significantly reduces postoperative air leak, time to drain removal and length of hospitalisation compared with no treatment. This shorter hospital stays results in significant cost saving benefits. Selection of patients with standardised VMT is essential to limit unnecessary intraoperative sealant treatments, thus contributing to limit the costs.
