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.

A Correction has been published | View Neurogenic tumors represent 10 to 34% of all mediastinal tumors and among them, neurofibroma originating from the vagus nerve are rare entities. We present a case of a neurofibroma with cystic degeneration originating from the left branch of the vagus nerve in a 27-year-old man without von Recklinghausen disease. A complete robotic resection of the mediastinal mass has been performed, with amputation of the vagus nerve enclosed in the mass. The postoperative course was uneventful and the patient was discharged in two days.

Background/Objectives: The surgical resection of pulmonary metastases is considered a therapeutic option in selected cases. In light of this, we present the results from a national multicenter prospective registry of lung metastasectomy. Methods: This retrospective analysis involves data collected prospectively and consecutively in a national multicentric Italian database, including patients who underwent lung metastasectomy. The primary endpoints were the analysis of morbidity and overall survival (OS), with secondary endpoints focusing on the analysis of potential risk factors affecting both morbidity and OS. Results: A total 470 lung procedures were performed (4 pneumonectomies, 46 lobectomies/bilobectomies, 13 segmentectomies and 407 wedge resections) on 461 patients (258 men and 203 women, mean age of 63.1 years). The majority of patients had metastases from colorectal cancer (45.8%). In most cases (63.6%), patients had only one lung metastasis. A minimally invasive approach was chosen in 143 cases (30.4%). The mean operative time was 118 min, with no reported deaths. Morbidity most frequently consisted of prolonged air leaking and bleeding, but no re-intervention was required. Statistical analysis revealed that morbidity was significantly affected by operative time and pulmonary comorbidities, while OS was significantly affected by disease-free interval (DFI) > 24 months (p = 0.005), epithelial histology (p = 0.001) and colorectal histology (p = 0.004) during univariate analysis. No significant correlation was found between OS and age, gender, surgical approach, surgical extent, surgical device, the number of resected metastases, lesion diameter, the site of lesions and nodal involvement. Multivariate analysis of OS confirmed that only epithelial histology and DFI were risk-factors, with p-values of 0.041 and 0.031, respectively. Conclusions: Lung metastasectomy appears to be a safe procedure, with acceptable morbidity, even with a minimally invasive approach. However, it remains a local treatment of a systemic disease. Therefore, careful attention should be paid to selecting patients who could truly benefit from surgical intervention.
RESUMO
BACKGROUND AND OBJECTIVE: Transbronchial needle aspiration (TBNA) is useful for diagnosing peripheral pulmonary lesions (PPL). However, TBNA is largely underused and the variables that may be related to its diagnostic usefulness have not been specifically studied. The aim of the present study was to evaluate the performance characteristics and predictors of yield from TBNA of PPL, and to compare the performance characteristics of different bronchoscopic sampling methods. METHODS: Consecutive patients with PPL were prospectively enrolled, and during the same examination, TBNA, transbronchial lung biopsy (TBLB) and bronchial washing (BW) were performed. RESULTS: Two hundred and eighteen PPL in 218 patients were sampled. TBNA was more sensitive (65%) than either TBLB (45%, P<0.001) or BW (22%, P<0.001). TBNA was the only diagnostic procedure in 42/196 patients (21%) with malignant lesions, and was more likely to be the only diagnostic procedure for lesions lacking (23/85 patients, 27%) than for lesions with the bronchus sign (19/111 patients, 17%). In multivariate analysis, a lesion size >2cm, malignancy and location in the middle lobe were independent predictors of a positive TBNA result. CONCLUSIONS: TBNA is the single best contributor to the success of bronchoscopy in the diagnosis of PPLs, and should be routinely used especially in the presence of lesions lacking the bronchus sign. Lesion size of > 2cm, location in the middle lobe, and malignant nature are strong predictors of a positive TBNA result.

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
Residual masses in patients with mediastinal lymphoma may be positron emission tomography (PET) positive during follow-up also in cases of complete response. The aim of this retrospective study is to verify the reliability of mediastinal PET-positive findings in suggesting disease relapse or progression during follow-up by histological verification. From January 2002 to March 2016, 96 patients with mediastinal lymphoma underwent PET follow-up after front-line treatment. A surgical biopsy was performed to confirm the suspected relapse (for a total of 113 procedures). A lymphoma relapse was diagnosed in 66/102 successful procedures (64.7%). Diagnosis at relapse was concordant with the initial diagnosis in all but 3 cases. Standardized uptake value was significantly higher among patients with relapse than among those who remained in remission (10 versus 5, p < .05). PET scan helps individuate patients with a high suspect of lymphoma relapse and may guide the surgeon to the most suitable target.

Broncho-pleural fistula (BPF) is an atypical communication between the tracheobronchial tree and the alveolar/pleural space, with prolonged air leak (PAL). BPF is frequent and related to significant morbidity, prolonged length of hospital stay, and mortality. Nevertheless, in about 10%, more than 5 days of an air leak is considered a PAL, accounted for significant morbidity. Endobronchial valve is a novel device for the PAL management with minimal morbidity if related to surgical repairs. While it is suggested that surgical treatment should be undertaken when possible, endobronchial valves should be recommended as a therapeutic choice in high-risk patients. Placement techniques remain operator and patient friendly and allow the procedure to be performed with relative ease. Prospectively conducted, randomised, controlled clinical trials are needed where valve treatment is compared with other bronchoscopic techniques, surgical procedures, or both.
RESUMO
In recent years, retrospective analyses have suggested that an oligometastatic state could exist, but the best evidence to date that a temporary oligometastatic disease exists for lung cancer mainly derives from the survival data on retrospective patients underwent surgical resection of a single M1 site and all intrathoracic disease. The critical determinates of long-term survival include definitive treatment of the primary non-small cell lung cancer (NSCLC), a single organ site of synchronous or metachronous disease, a long disease-free interval between treatment of the primary NSCLC and development of metastases, and the absence of intrathoracic lymph node (N0) disease. The ongoing development of innovative approaches to local therapy and treatment directed to the oligometastatic sites should be defined in future studies.
RESUMO
Synchronous cancers are not such rare clinical conditions. Nevertheless, even after the 8th edition of the TNM classification of the lung cancer, the surgical approach for patients presenting with synchronous bilateral lung cancer is still under debate. The resection of both lesions in the case of synchronous bilateral lung cancer is reasonable, but, on the other hand, is the lobectomy the correct choice in the event of the single primary with a contralateral metastatic lesion? In this case report, we describe how the molecular analysis and the detection of the EGFR, KRAS and TP53 mutations in both tumours have determined in a patient the two tumours as primary and both the right surgical approach. We also discuss how molecular analysis found differences in all the three genes examined in the two lesions and allowed to exclude the clonal nature of the two tumours. In conclusion, genetic studies help to offer a more radical surgical treatment to this patient.
RESUMO
We report on the successful surgical treatment of an esophageal-bibronchial fistula originating from an iatrogenic mediastinal abscess. Endoscopic treatment had been excluded due to the extensive damage to the right main stem bronchus wall. The surgical treatment was carried out as follows: 1) Endoscopic stenting of the left main bronchus with a self-expanding metallic stent followed by selective left main bronchus intubation; 2) Laparotomic harvesting of the omentum pedicled on both gastro-epiploic vessels; 3) Right thoracotomy, complete dissection of both main bronchi and esophageal wall at the site of the leakage; 4) Harvesting of a pericardial vascularized graft; 5) Deployment of a self-expanding metallic stent from the surgical field into the right main stem bronchus; 6) Reconstruction of the right bronchus wall with the pericardial patch; 7) Positioning a T-tube in the esophageal leak; and 8) Intrathoracic transposition of the omental graft for buttressing all sutures and potential leakage points. The postoperative course was uneventful from a surgical point of view and the patient recovered completely.
