Background: The Nuss procedure is the primary treatment for pectus excavatum (PE), but patient expectations are not always met. In our unit, our standard approach in the last few years has been the routine application of two bars instead of one. We aimed to retrospectively assess the impact of this approach on patient satisfaction, quality of life (QoL) and safety., Methods: A retrospective study included 182 patients over 16 years old who underwent the Nuss procedure for PE between January 2007 and September 2021. Patients were categorized into one-bar or two-bar correction groups. Propensity score matching (PSM) was used, resulting in 30 patients in each group. Primary endpoints were QoL and cosmetic satisfaction, while secondary endpoints included complications and recurrence., Results: After PSM, both groups showed similar general characteristics. Patients treated with two bars reported fewer psychological complaints post-surgery (93.3% vs. 73.3%, p  = 0.031). There were no significant differences in QoL improvement (96.7% in both groups, p  = 0.197), perioperative complications ( p  = 0.771) or recurrence (one patient in the one-bar group, p  = 1.000)., Conclusions: Our study reveals that patients undergoing the Nuss Procedure for PE with two bars exhibit comparable clinical outcomes and QoL to those with one bar. However, patients with two bars may have higher levels of psychological well-being and satisfaction, indicating potential benefits associated with this approach. These findings suggest potential advantages of the two-bar approach, but further research with larger sample sizes is warranted to confirm these observations., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Nicotine addiction is a widespread, worldwide epidemic, causing six million deaths per year. A large variety of treatments for smoking cessation are currently available, including Cytisine, which is a promising drug due to its low cost and high safety levels. Notwithstanding the important amount of research on tobacco addiction treatments, smoking remains one of the most difficult substance use disorders to treat, probably also due to the fact that pharmacological treatment often overlooks other maintaining factors in this addiction, such as sensory impact and cue reactivity. To address this gap in both treatment protocols and scientific literature, we propose a study protocol in which we will compare the effects of combining Cytisine with Nirdosh, a herbal tobacco substitute, to Cytisine only in two groups of patients (C + N and C) who will also undergo exposure to four different virtual reality settings that will assess the importance of environmental cues. We will further assess mood and craving in the two samples, and include a control group taken from the general population. We expect the C + N group to report a more positive mood and a lower sensitivity to tobacco-related environmental cues., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Zamboni, Campagnari, Giordano, Fusina, Carli, Congiu, Barbon, Melchiori, Casari, Tedeschi, Vesentin, Verlato, Infante and Lugoboni.)

Background: Persistent air leak and the management of intraoperative blood loss are common threats in thoracic surgical practice. The availability of new procedures, technology and materials is constantly evolving topical hemostats and surgical sealants must be added to this toolkit. Topical hemostats and surgical sealants differ according to their chemical nature and physical characteristics, to their origin and mechanism of action, regulatory/registration and vigilance paths. A Delphi consensus was set to highlight the different points of view on the use of topical haemostatic products and sealants among the members of Italian Society of thoracic surgery., Methods: The board was formed by a group of five Italian experts; in the first phase after a careful review of the scientific literature and two rounds, the board finally generated 16 consensus statements for testing across a wider audience. During the second phase, the statements were collated into a questionnaire, which was electronically sent to a panel of 46 Italian surgeons, experts in the field., Results: Out of 46 Italian surgeons, 33 (72%) panel members responded to the Delphi questionnaire. All the items reached a positive consensus, with elevated levels of agreement, as demonstrated by the presence of a 100% consensus for nine items. For the remaining 7 statements the minimum level of consent was 88% (29 participants approved the statement and 4 disagreed) and the maximum was 97% (32 participants approved the statement and 1 was in disagreement)., Conclusions: The present Delphi analysis shows that air leak and intraoperative bleeding are clinical problems well known among thoracic surgeons. Nevertheless, the aim of the scientific societies and of the group of experts is to execute the education activities in the surgery community. This Delphi survey suggest the need of wider and updated scientific information about technical and registration characteristics of most recent technologic solutions, such as the of topical hemostats and surgical sealants to provide healthcare and administrative staff with the opportunity to work and interact through a common and shared language and eventually to guarantee minimal requirements of assistance., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-22-619/coif).

Background: Tracheal cancer is a rare malignancy of which previous reports are mostly case reports or small series. Herein, we sought to evaluate the clinical characteristics, surgical treatments, and prognosis of surgically treated primary tracheal cancer patients., Methods: Patients with primary tracheal cancer who had received surgery in our center between January 2000 and December 2020 were enrolled. Clinical and surgical features were collected by retrospective review of medical records and follow-up was done by telephone interview. The statistical tests were two-sided., Results: A total of 128 patients were included in the study, 49.2% of whom were male, and the average age was 49.4±13.6 years. The most common histological subtype was adenoid cystic carcinoma (ACC; 78/128, 60.9%) followed by squamous cell carcinoma (SCC; 24/128, 18.8%). The percentage of tumors located in the cervical trachea, thoracic trachea, and carina were 50%, 41.4%, and 8.6%, respectively. Among those analyzed, 32.0% of the primary tumors had invaded adjacent organs (E2 disease) and 7.8% of patients had lymph node involvement. Tracheal resection plus reconstruction (with or without thyroidectomy) was the predominant surgical procedure, followed by carinal resection with neocarina. Radical resection (R0) was performed on 61.7% of patients and 63 (49.2%) patients received adjuvant therapy. Compared to ACC, SCC patients had significantly higher risk of tumor of the carina, nodal metastasis, and complications. The 5-year overall survival (OS) for the entire cohort was 84.5% and factors associated with poor prognosis included carinal tumor [hazard ratio (HR) =10.206; P<0.001], E2 disease (HR =8.870; P=0.001), lymph node metastasis (HR =15.197; P<0.001), and postoperative complications (HR =12.497; P=0.001)., Conclusions: The two major subtypes of tracheal cancer are ACC and SCC. Tumor location, extension, lymph node metastasis and complication are survival related factors for surgically treated patients., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tlcr.amegroups.com/article/view/10.21037/tlcr-22-258/coif).

Background : Persistent air leak is a common complication after lung resection causing prolonged length of stay and increased healthcare costs. Surgical intervention can be an option, but other more conservative approaches should be considered first. Here, we describe the use of flexible bronchoscopy to apply fibrin glue and autologous blood sequentially to the damaged lung. We named the technique "flexible thoracoscopy"., Methods: Medical records from patients with persistent air leaks after lung resection were collected retrospectively. Depending on the type of aerostasis that was performed, two groups were created: flexible thoracoscopy and surgery (thoracotomy). Flexible thoracoscopy was introduced at our institution in 2013. We entered the pleural space with a bronchoscope following the same surgical pathway that was used for tube thoracostomy. Perioperative characteristics and outcomes were analyzed using R software (ver. 3.4.4)., Results: From 1997 to 2021, a total of 23 patients required an intervention for persistent air leaks. Aerostasis was performed via flexible thoracoscopy in seventeen patients (69%) and via thoracotomy in six patients (31%). The median age was 70 years (22-82). Twenty patients were males (87%). There was no difference in age, sex distribution, BMI, comorbidities and FEV1%. An ASA score of 3 was more represented in the flexible thoracoscopy group; however, no evidence of a difference was found when compared to the thoracotomy group ( p = 0.124). Length of in-hospital stay and chest tube duration was also similar between groups ( p = 1 and p = 0.68, respectively)., Conclusions: Aerostasis achieved either by flexible thoracoscopy or by thoracotomy showed similar results. We believe that flexible thoracoscopy could be a valid alternative to facilitate minimally invasive treatments for persistent air leaks. Further studies are needed to confirm these results.
