Objectives: This study reports the results of an international expert consensus process evaluating the assessment of intraoperative air leaks (IAL) and treatment of postoperative prolonged air leaks (PAL) utilizing a Delphi process, with the aim of helping standardization and improving practice., Methods: A panel of 45 questions was developed and submitted to an international working group of experts in minimally invasive lung cancer surgery. Modified Delphi methodology was used to review responses, including 3 rounds of voting. The consensus was defined a priori as >50% agreement among the experts. Clinical practice standards were graded as recommended or highly recommended if 50-74% or >75% of the experts reached an agreement, respectively., Results: A total of 32 experts from 18 countries completed the questionnaires in all 3 rounds. Respondents agreed that PAL are defined as >5 days and that current risk models are rarely used. The consensus was reached in 33/45 issues (73.3%). IAL were classified as mild (<100 ml/min; 81%), moderate (100-400 ml/min; 71%) and severe (>400 ml/min; 74%). If mild IAL are detected, 68% do not treat; if moderate, consensus was not; if severe, 90% favoured treatment., Conclusions: This expert consensus working group reached an agreement on the majority of issues regarding the detection and management of IAL and PAL. In the absence of prospective, randomized evidence supporting most of these clinical decisions, this document may serve as a guideline to reduce practice variation., (© The Author(s) 2022.

Objectives: Preoperative selection bias led to the inability to generalize the proposed benefit of subxiphoid uniportal video-assisted thoracoscopic surgery (SVATS) as having less postoperative pain than uniportal intercostal VATS. So, we conducted this prospective, single-blinded, randomized controlled trial to investigate the hypothesis that SVATS may have less early postoperative pain than UVATS in patients who undergo major lung resection for early-stage lung cancer., Methodsa Total of: 262 patients were randomly allocated between 2 groups (each with 131 patients), the first being the UVATS group and the second being the SVATS group. The values indicated on the numerical rating scale (NRS) of pain were collected at 24 h and 48 h during rest and during coughing. In addition, different perioperative variables were analysed and compared between the 2 groups., Results: Multiple linear regression analysis showed that the type of surgical approach was a significant predictor of the postoperative NRS values. The postoperative NRS pain values were significantly lower in the SVATS group after 24 h during rest and coughing and after 48 h during coughing. Postoperatively, patients in the SVATS group got out of bed significantly earlier [16.37 (2.54) vs 18.05 (3.29) h, p < 0.001]. The SVATS group showed a significantly higher rate of intraoperative arrhythmia [20 (15.3%) vs 3 (2.3%) patients, p = 0.03]., Conclusions: SVATS major pulmonary resection in early-stage lung cancer is associated with less early postoperative pain than the UVATS approach. Operating on patients with cardiac problems using the SVATS approach is still a limiting factor for randomization due to the potential compression on the heart with resulting arrhythmia., Clinical Trial Registration: The trial was registered under clinical trials.gov Identifier: NCT03331588. https://clinicaltrials.gov/ct2/show/NCT03331588., (© The Author(s) 2022.

General thoracic surgery operations in Egypt are performed mainly by cardiothoracic surgeons and less oftenly by dedicated thoracic surgeons and general surgeons. This is mainly due to the relatively small number of thoracic surgeons in relation to population as only 210 cardiothoracic surgery specialists and 458 consultants are registered with the Egyptian Medical Syndicate (EMS) in a country with a population of more than 100 million people. Thoracic surgeons in Egypt are faced with a number of burdens, including the need to propagate the service to advanced technology infront of the obstacle of limited resources. Other burdens include higher incidence of TB, trauma and foreign body inhalation related to cultural backgrounds. More centres now are major video-assisted thoracic surgery (VATS) providing centres and others are specialized in more complex surgeries like complicated airway procedures and radical surgery for mesothelioma. As part of the international community, the COVID-19 pandemic has put more burdens on the thoracic surgery service as most centres have reduced their elective surgery workload to less than half of usual. Interestingly, the pandemic has allowed a self-referral screening programme with widespread Computed Tomography (CT) chest being performed among the population allowing thoracic surgeons to operate more on early stage lung cancer. The academic challenges for thoracic surgeons are even more with need for developing national databases. Nevertheless, thoracic surgeons in Egypt are optimistic regarding the future. The rising interest among the younger population will push training programs to meet the interests of enthusiastic junior surgeons. While the ancient history of thoracic surgery in Egypt seems to be extraordinary, the future perspectives promise to be more rewarding., Competing Interests: Conflicts of Interest: The authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-21-723/coif).

Objectives: Subxiphoid uniportal video-assisted thoracoscopic segmentectomy (SU-VATs) has been widely adopted because it is associated with better postoperative pain scores. Nevertheless, it also has had some limitations that have gradually been decreasing. Therefore, our goal was to evaluate the change in perioperative results with SU-VATs as the learning curve developed to outline the current status and the points that should be of future concern., Methods: Three hundred patients who underwent SU-VATs from September 2014 to May 2018 were divided chronologically into 2 groups; group 1 comprised the first 150 cases and group 2 comprised the last 150 cases. Different perioperative variables were analysed and compared between the 2 groups. In addition, the cumulative sum analysis and multivariable logistic regression were conducted to identify the cut-off point and predictors of significant improvement in operative time., Results: The cumulative sum analysis showed significant improvement in the operative time after the 148th case. Group 2 showed a statistically significant decrease in operative time (104.3 ± 36.7 vs 132 ± 43.1 min; P < 0.001), amount of operative blood loss [50 (80 ml) vs 100 (50 ml); P < 0.001], chest drain duration (2.6 ± 1.6 vs 3.2 ± 1.4 days; P = 0.004) and hospital stay (3.7 ± 1.7 vs 4.2 ± 1.7 days; P = 0.008). The number of dissected lymph nodes was significantly higher in the second group [11 (4) vs 9 (4); P < 0.001]., Conclusions: Limitations of SU-VATs are being overcome by the improvement in the learning curve and in the expertise of the surgeons. Our future concerns should focus on examining the long-term survival rate, the oncological efficacy and the effect on quality of life., (© The Author(s) 2020.

Background: Subxiphoid uniportal video-assisted thoracoscopic surgery (SVATS) is more technically challenging than intercostal uniportal video-assisted thoracoscopic surgery (UVATS), especially in more complex procedures such as segmentectomy. We therefore aimed to investigate the worthiness of undertaking the more demanding subxiphoid approach in patients who had undergone anatomical segmentectomy for stage IA non-small cell lung cancer (NSCLC)., Methods: A total of 491 patients were included in our study who had undergone anatomical segmentectomy for stage IA non-small cell lung cancer from September 2014 to April 2018. They were divided into two groups; 278 patients in the UVATS group and 213 patients in the SVATS group. Different perioperative variables, postoperative pain, quality of life and cost were analyzed and compared between both groups., Results: The SVATS group showed a significantly longer operative time (P = 0.007) and more operative blood loss than the intercostal group (P = 0.004). There was no significant difference between both groups regarding postoperative drainage, duration of chest tube, postoperative hospital stay, operative conversion or postoperative complications. The SVATS group showed a significantly lower pain score postoperatively (P < 0.001). In addition, the SVATS group showed a significantly better postoperative quality of life score along the first postoperative year (P < 0.001). UVATS segmentectomy appeared to be significantly cheaper than SVATS segmentectomy (P < 0.001)., Conclusions: SVATS segmentectomy for stage IA lung cancer is a safe procedure that is worth proceeding with as it is associated with better postoperative pain and better quality of life in the first postoperative year. Further studies are recommended to evaluate the actual cost-effectiveness of SVATS segmentectomy., Key Points: • Significant findings of the study Subxiphoid uniportal approach for pulmonary segmentectomy is safe and feasible approach. It has better postoperative pain and better quality of life than the uniportal intercostal approach; however, it is more expensive. • What this study adds Subxiphoid uniportal approach for pulmonary segmentectomy gives a better quality of life in Chinese patients than the intercostal approach; however, it is more expensive., (© 2020 The Authors.

Background: Myocardial damage due to ischemia and reperfusion is still unavoidable during coronary surgery. Anesthetic agents have myocardial preconditioning effect. Ketamine has sympathomimetic effect, while dexmedetomidine has a sympatholytic effect in addition to anesthetic, analgesic, and anti-inflammatory properties of both the drugs. This study was carried out to compare ketamine-dexmedetomidine (KD) combination with fentanyl-propofol (FP) combination on the release of cardiac troponin T (cTnT) and outcome after coronary artery bypass graft., Patients and Methods: Ninety adult patients who underwent coronary artery bypass grafting (CABG) were assigned to receive either KD base anesthesia (KD group) or FP anesthesia (FP group). Trends of high-sensitive cTnT, CK-MB, and serum cortisol were followed in the first postoperative 24 h. Other outcomes were vital signs, weaning from cardiopulmonary bypass, tracheal extubation time, and echocardiographic findings., Results: There was a significant lower release of cTnT in KD group than FP group during its peak values at 6 h after aortic unclamping (92.01 ± 7.332 in KD versus 96.73 ± 12.532 ng.L -1 P = 0.032). significant lower levels of serum cortisol levels were noted KD group than in FP group at 6 and 12 h after aortic unclamping P < 0.001. As regard tracheal extubation time, patients assigned to KD group extubated earlier than whom in FP group 202.22 ± 28.674 versus 304.67 ± 40.598 min respectively P < 0.001., Conclusion: The use of KD during on-pump CABG confers better myocardial protective and anti-inflammatory effect than fentanyl propofol., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Anesthesia: Essays and Researches.)

The subxiphoid approach to video-assisted thoracic surgery (VATS) has been introduced as an alternative to intercostal VATS. There is some evidence that avoiding intercostal incision and instrumentation leads to reduced pain and facilitates early mobilisation and enhanced recovery. Access of the pleural cavities and anterior mediastinal space through a subxiphoid incision presents some challenges, particularly when accessing posterior pulmonary lesions. With increasing experience, a large range of thoracic surgical operations performed through the subxiphoid approach have been reported including anatomical segmentectomies, thymectomies. Another attraction is that bilateral procedures can be performed through a single incision. The experience of several surgeons passing through the learning curve of subxiphoid VATS surgery has resulted in overcoming many of the early challenges faced. In this paper, a series of tips and tricks are presented to enable surgeons considering adopting this technique into their practice to do so safely and with an appreciation of the difficulties that they may face., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Introduction: Tracheal stenosis is a complex condition caused by altered inflammatory response to injury and subsequent excessive circumferential scar formation. Surgical resection, wherever possible, offers the best long-term results. Nonsurgical methods provide immediate relief to all can be curative in few but mostly serve as an excellent bridge to surgery in majority. The purpose of this study is to retrospectively evaluate the outcome following surgery for benign tracheal stenosis at our center., Materials and Methods: This retrospective analysis was conducted on 18 patients who underwent resection and anastomosis for tracheal stenosis at our center between March 2012 and December 2015. Their records were analyzed for demography, history, clinical presentation, computed tomography, bronchoscopy details, preoperative interventions, indications for and details of surgery, the procedure performed, postoperative complications, and course during 6 months follow-up., Results: The patients had a varied list of pathologies for which they were either intubated or tracheostomized. The length of stenosis ranged between 1 cm and 4 cm. The diameter of stenotic segment ranged between 0 mm and 10 mm. Average length of resected segment was 3 cm, and number of tracheal rings resected ranged from 2 to 9. Postoperative complications occurred in four patients (22.22%). All our patients were in the "excellent outcome" category at discharge as well as at 3 months follow-up., Conclusions: Surgical management of tracheal stenosis is challenging and requires multidisciplinary team approach. Thorough preoperative preparation and multidisciplinary planning regarding need for and timing of surgery, meticulous intraoperative technique, and aggressive postoperative care is key to successful surgery, which can provide long-lasting cure to these patients.
