Objectives: To provide a short overview of fast-track video-assisted thoracoscopic surgery (VATS) and to identify areas requiring further research.Design: A literature search was made using key words including: fast-track, enhanced recovery, video-assisted thoracoscopic surgery, robot-assisted thoracoscopic surgery (RATS), robotic, thoracotomy, single-incision, uniportal, natural orifice transluminal endoscopic surgery (NOTES), chest tube, air-leak, digital drainage, pain management, analgesia, perioperative management, anaesthesia and non-intubated. References from articles were screened for further articles. Using abstracts, areas of interest for developing a fast-track protocol were selected.Results: The minimally invasive approach can be divided into several surgical methods that need further research to establish superiority. The role of intubation has to be further examined as well as the role of chest drains. Multimodal analgesic treatment including preoperative methylprednisolone seems promising and requires further research.Conclusions: The fast-track data from other procedures may support future development and improvement of fast-track VATS.

OBJECTIVES: Lung cancer is the most common cause of cancer-related deaths worldwide. Survival is highly dependent on surgery. Videoassisted thoracoscopic surgery (VATS) is increasingly chosen over open thoracotomy (OT) because of the possible benefits of the minimally invasive approach. Consequently, our aim was to compare the 30-day morbidity and mortality for lung cancer patients operated by VATS lobectomy or lobectomy by OT. METHOD: Data were obtained from prospective national and regional databases, including patients who underwent lobectomy for lung cancer in the eastern part of Denmark from 1 January 2005 to 31 December 2011. All patients operated before 2009 were re-staged according to the latest International Association for the Study of Lung Cancer lung cancer classification. Patient characteristics, comorbidities, pathology and operative data were assessed using an independent samples t-test, Pearson's ?2, Fisher's exact test and Mann-Whitney test. Morbidity was assessed using multinomial logistic regression adjusted for gender, age, cancer stage, forced expiratory volume in 1 s (FEV1), year of surgery and Charlson comorbidity score. RESULTS: In total, 1379 patients underwent lobectomy, 785 patients via VATS and 594 patients via thoracotomy. The two groups were similar in gender and FEV1. The patients operated by VATS were older (P < 0.001), and had a lower Charlson comorbidity score (P = 0.034), higher frequency of adenocarcinomas (P < 0.001) and lower cancer stage (P < 0.001). Among the VATS patients, 285 (36.3%) and among the thoracotomy patients, 288 (48.5%) had minor complications (P < 0.001); and 157 (20.0%) VATS patients and 212 (35.7%) thoracotomy patients had major complications (P < 0.001). The 30-day mortality rate was 1% in the VATS group and 1.5% in the thoracotomy group (P = 0.47). Multinomial logistic regression analysis showed that the prevalence of both minor [odds ratio (OR) = 1.51; 95% confidence interval (Cl) = 1.18-1.96] and major complications (OR = 1.91, 95% Cl = 1.44-2.53) was significantly higher for patients who underwent lobectomy via thoracotomy compared with VATS. CONCLUSION: Patients undergoing lobectomy via VATS were less likely to have at least one minor complication within the first 30 postoperative days and less likely to have at least one major complication, compared with patients operated by thoracotomy. These findings remained after adjusting for gender, age, FEV1, cancer stage, year of surgery and Charlson comorbidity score. [ABSTRACT FROM AUTHOR]

Video-assisted thoracic surgery (VATS) is emerging as the standard surgical procedure for both minor and major oncological lung surgery. Thoracic epidural analgesia (TEA) and paravertebral block (PVB) are established analgesic golden standards for open surgery such as thoracotomy; however, there is no gold standard for regional analgesia for VATS. This systematic review aimed to assess different regional techniques with regard to effect on acute postoperative pain following VATS, with emphasis on VATS lobectomy. The systematic review of PubMed, The Cochrane Library and Embase databases yielded 1542 unique abstracts; 17 articles were included for qualitative assessment, of which three were studies on VATS lobectomy. The analgesic techniques included TEA, multilevel and single PVB, paravertebral catheter, intercostal catheter, interpleural infusion and long thoracic nerve block. Overall, the studies were heterogeneous with small numbers of participants. In comparative studies, TEA and especially PVB showed some effect on pain scores, but were often compared with an inferior analgesic treatment. Other techniques showed no unequivocal results. No clear gold standard for regional analgesia for VATS could be demonstrated, but a guide of factors to include in future studies on regional analgesia for VATS is presented. [ABSTRACT FROM AUTHOR]

OBJECTIVES In fast-track pulmonary resections, we removed chest tubes after video-assisted thoracic surgery (VATS) lobectomy with serous fluid production up to 500 ml/day. Subsequently, we evaluated the frequency of recurrent pleural effusions requiring reintervention. METHODS Data from 622 consecutive patients undergoing VATS lobectomy from January 2009 to December 2011 were registered prospectively in an institutional database. Data included age, gender, lobe(s) resected, bleeding and duration of surgery. Follow-up was 30 days from discharge. All complications requiring pleurocentesis or reinsertion of a chest tube, and all readmissions were registered. Twenty-three patients were excluded due to missing data, in-hospital mortality and loss to follow-up, leaving 599 for final analysis. Our primary outcome was the number of patients requiring reintervention due to recurrent pleural effusion. Secondary outcomes included time of chest tube removal and time to discharge. The incidence of recurrent pleural effusions requiring reintervention was compared between three groups according to the postoperative day (POD) of chest tube removal (Day 0–1, 2–3 and ≥4, respectively) using Fisher's exact test. RESULTS Pleural effusion after chest tube removal required reintervention in 17 patients (2.8%). Of these, 7 needed readmission. Median time from surgery to chest tube removal was 2 days, and median time from surgery to discharge was 4 days. No statistically significant association was found between the incidence of reinterventions due to recurrent pleural effusion and the POD of chest tube removal (P = 0.50). The median time from chest tube removal to discharge was 1 day in all groups. Of the patients who needed reintervention, none had complications regarding this, except one who developed pneumothorax after pleurocentesis. CONCLUSIONS Our findings suggest that chest tube removal after VATS lobectomy is safe despite volumes of serous fluid production up to 500 ml/day. The proportion of patients who developed pleural effusion necessitating reintervention was low (2.8%), and a complication of the reintervention was seen in only 1 patient. [ABSTRACT FROM PUBLISHER]

Video-assisted thoracic surgery (VATS) lobectomy has become an accepted, safe, and oncologically effective strategy in the surgical management of early stage lung cancer. In this review we have focused on papers concerning patient care and outcome. On the short-term base, VATS lobectomy is associated with less postoperative pain, shorter chest tube duration, shorter length of hospital stay, shorter stay in an intensive care unit (ICU), less intraoperative blood loss, less need for blood transfusion, and less complications. On the long-term base, VATS lobectomy is associated with less chronic pain, better preservation of lung function, earlier return to daily activities, and better shoulder function. Furthermore, VATS lobectomy is less immunosuppressive and seems to facilitate the deliverance of adjuvant chemotherapy. The 5- year survival rate is comparable to or maybe even better than a lobectomy by thoracotomy. We expect VATS lobectomy to be the standard operation in early stage lung cancer in the near future.

Objectives: Lung volume reduction (LVR) is an efficient and approved treatment for selected emphysema patients. There is some evidence that repeated LVR surgery (LVRS) might be beneficial, but there are no current data on LVRS after unsuccessful bronchoscopic LVR (BLVR) with endobronchial valves (EBVs). We hypothesize good outcome of LVRS after BLVR with valves., Methods: In this study, we retrospectively investigated all patients who underwent LVRS between 2015 and 2019 at 2 centres after previous unsuccessful EBV treatment. They were further divided into subgroups with patients who never achieved the intended improvement after BLVR (primary failure) and patients whose benefit was fading over time due to the natural development of emphysema (secondary failure). Patients with severe air leak after BLVR and immediate concomitant LVRS and fistula closure thereafter were analysed separately., Results: A total of 38 patients were included. Of these, 19 patients had primary failure, 15 secondary failure and 4 were treated as an emergency due to severe air leak. At 3 months after LVRS, forced expiratory volume in 1 s had improved significantly by 12.5% (P = 0.011) and there was no 90-day mortality. Considering subgroups, patients with primary failure after BLVR seem to profit more than those with secondary failure. Patients with severe air leak after BLVR did not profit from fistula closure with concomitant LVRS., Conclusions: LVRS after previous BLVR with EBVs can provide significant clinical improvement with low morbidity, although results might not be as good as after primary LVRS., (© The Author(s) 2020.

Lung volume reduction surgery (LVRS) is a treatment option for patients with severe emphysema. A multicentre randomised trial (NETT) found, that LVRS reduced symptoms from emphysema, and in selected patients with heterogen-ous emphysema it improved survival. Since NETT was performed, other studies have demonstrated positive outcomes, both symptomatic and for survival in previously classified high-risk patients. Post-operative mortality after LVRS is now negligible, which is often credited to minimally invasive techniques, greater experience with the patient group and improved operative equipment.

This review is about the initial diagnostic workup and the surgical treatment of patients with lung cancer in Denmark. Due to the development of international and national clinical guidelines for diagnosis and treatment of lung cancer, survival has increased. Data from 2005-2016 in the National Danish Lung Cancer Registry show an increase in: 1) the number of women being diagnosed, 2) the part of surgical candidates being thoracoscopically treated, 3) the number of patients being referred to surgery and 4) the survival rate.

Objective: Microlobectomy is a novel form of videoscopic-assisted thoracic surgery lobectomy. Strict inclusion criteria consist of the following: no intercostal incisions greater than 5 mm, 12 mm subxiphoid port, subxiphoid removal of the specimen, total endoscopic technique with CO2 insufflation, vision through a 5-mm camera, stapling via the subxiphoid port, or with 5-mm stapling devices., Methods: The combined early experiences of six hospitals from three countries were combined from September 2014 to May 2016. During that time, the study represents a consecutive cohort study of this technique., Results: Seventy-two patients underwent microlobectomy. The median (range) age was 66 (27-82). Half of the patients were female. There were 48 right-sided resections and 24 on the left. There were four segmental resections and there was one right pneumonectomy. Four operations were performed robotically (with 8-mm intercostal incisions). The median (range) operative time was 180 (94-285) minutes and the blood loss was 118 (5-800) mL. There were three conversions to thoracotomy and two conversions to videoscopic-assisted thoracic surgery by means of an intercostal utility incision to complete the operation. The median (range) length of stay was 3 (1-44) days and 30 patients (42%) when home by day 2 and 16 patients (22%) were discharged on day 1. There were no deaths. Five patients (7%) had a prolonged airleak. There were no wound infections and there was one incisional hernia., Conclusions: We believe that microlobectomy is an interesting novel form of videoscopic-assisted thoracic surgery lobectomy and has several theoretical advantages. We have presented our early results and hope that this will stimulate others to investigate this type of videoscopic-assisted thoracic surgery lobectomy further.

Video-assisted thoracoscopic surgery (VATS) has undergone significant evolution over several decades. Although endoscopic instruments continued to improve, it was not until 1992 that the first VATS lobectomy for lung cancer was performed. Despite significant seeding of such procedure in several thoracic units globally, the uptake was slow and frustrating. Many surgeons considered it complex and unsafe being skeptic about its oncological validity. The last decade has witnessed significant change of practice in many thoracic units with a new generation of VATS thoracic surgeons. Additionally the technique has been refined, standardized and proved its validity and superiority in lung cancer treatment.

Introduction: An increasing proportion of thoracic procedures are performed using video-assisted thoracic surgery. This minimally invasive technique places special demands on the surgeons. Using simulation-based training on artificial models or animals has been proposed to overcome the initial part of the learning curve. This study aimed to investigate the effect of simulation-based training and to compare self-guided and educator-guided training., Methods: The study included a surgeon group (n = 10) and 30 randomized novices in 3 groups. A control group (n = 10) and the group of surgeons (n = 10) were tested with no previous simulator training. A self-guided training group (n = 10) and an educator-guided training group (n = 10) trained for 3 hours on 3 scenarios of increasing fidelity and difficulty before taking a standardized test consisting of performing a wedge resection on a porcine lung, which was recorded and assessed blindly and independently by 2 thoracoscopic experts using a modified version of a validated assessment tool., Results: Interrater reliability was acceptable (Spearman ρ = 0.73, P < 0.001). The control group and the self-guided training group performed significantly worse than the experienced surgeons (P = 0.012 and P = 0.010, respectively). There was no significant difference between the educator-guided training group and the experienced surgeons (P = 0.271)., Conclusions: This randomized study concerning simulation-based training for thoracoscopy showed that 3 hours of intensive simulator training with a dedicated educator enables novices to perform an acceptable wedge resection in a simple, simulated model. Although not significant, it seemed that having an educator present during training had a beneficiary effect. Transfer studies are required for further conclusions.

Objectives: Lobectomies done by video-assisted thoracic surgery (VATS) result in fewer complications and less pain and save total costs compared with the traditional approach. However, the majority of procedures are still performed via open thoracotomies, because VATS lobectomy is considered difficult to learn, requiring experience in open surgery, and causing complications in the initial phase of the learning curve. The aim of this study was to describe a training model appreciating patient safety during training and to explore the initial learning curve for a trainee rather inexperienced in open surgery., Methods: A trainee who had performed 14 lobectomies by thoracotomy was enrolled in a training programme at a high-volume VATS centre. The training model included courses and simulations followed by the selection of suitable patients operated on during close expert supervision. Data regarding time, a variety of quality indicators and complications were collected prospectively and compared with experts' performance., Results: Over 12 months, 29 of 214 VATS lobectomies were performed by the trainee. Twice, the supervisor had to finish the procedure due to technical difficulties. None of the operations were converted to open thoracotomy. Compared with experts, the trainee operated significantly slower [median 120 (range 74-160) vs 100 (range 42-255) min, P = 0.04]; had similar perioperative bleeding [median 100 (range 10-500) vs 50 (range 5-2500) ml, P = 0.79]; had earlier chest tube removal [median 1 (range 1-6) vs 2 (range 1-32) postoperative days, P < 0.001]; and reduced hospital stay [median 3 (range 1-10) vs 4 (range 1-41) days, P < 0.001]. Twenty-three (79%) patients had no complications, while 2 had atrial fibrillation. Pneumothorax after chest tube removal, incisional infection, prolonged pain and need for pleuracentesis were each seen once., Conclusions: With thorough preparation of trainees and training on selected patients under close supervision, the learning curve can be overcome with good results even if the trainee has limited prior experience in open surgery.

Introduction: Esophageal perforation can within hours result in seriously-ill patients with a high risk of complications. The array of treatment options is many and minimal invasive methods are emerging., Materials and Methods: Six patients with esophageal perforations, who were managed successfully by thoracoscopic debridement, irrigation and drainage. The causes of the lesions and the importance of early diagnosis are described. The different treatment schemes are outlined, and the specifics of this thoracoscopic approach are described. The importance of port placement is underlined and illustrated in Figure 1., Results: The six patients with a median age of 70.5 years (29-80) were successfully treated with videothoracoscopic debridement, irrigation with saline and drainage. Median time in surgery was 91.5 min. and the in-hospital time was 17.5 days. There were no complications except for one patient with continuous bacterial contamination of the pleural cavity, necessitating chest tube treatment for weeks after discharge. No patient was re-operated nor had a fatal course., Discussion: The potential applications of thoracoscopic surgery as a minimal invasive treatment for esophageal perforations are discussed, as well as the advantages of a combination of videothorascopic drainage and placement of a covered expandable stent. This combination must be evaluated in future studies.

Introduction: This article reports the introduction of VATS (video-assisted thoracic surgery) lobectomy in lung cancer patients in our department., Methods: From 22 October 1999 to 15 December 2000, ten patients with peripheral primary lung cancer with no signs of spreading underwent VATS lobectomy. In an additional four patients, the resection started as VATS, but had to be converted to an open procedure., Results: No 30 day mortality or late complications were seen. One patient who developed empyema underwent surgery and one had a stroke, but with total remission., Discussion: We have shown that it is possible to introduce VATS lobectomy with acceptable results. A literature overview demonstrates that thoracoscopic lobectomies offer similar survival data to that of conventional surgery.
