British societies guideline on the management of emergencies in implantable left ventricular assist device recipients in transplant centres.

An implantable left ventricular assist device (LVAD) is indicated as a bridge to transplantation or recovery in the United Kingdom (UK). The mechanism of action of the LVAD results in a unique state of haemodynamic stability with diminished arterial pulsatility. The clinical assessment of an LVAD recipient can be challenging because non-invasive blood pressure, pulse and oxygen saturation measurements may be hard to obtain. As a result of this unusual situation and complex interplay between the device and the native circulation, resuscitation of LVAD recipients requires bespoke guidelines. Through collaboration with key UK stakeholders, we assessed the current evidence base and developed guidelines for the recognition of clinical deterioration, inadequate circulation and time-critical interventions. Such guidelines, intended for use in transplant centres, are designed to be deployed by those providing immediate care of LVAD patients under conditions of precipitous clinical deterioration. In summary, the Joint British Societies and Transplant Centres LVAD Working Group present the UK guideline on management of emergencies in implantable LVAD recipients for use in advanced heart failure centres. These recommendations have been made with a UK resuscitation focus but are widely applicable to professionals regularly managing patients with implantable LVADs.

Results of an exploratory survey within ESTS membership in 2022 on current trend of robotic-assisted thoracic surgery and its training perspectives.

OBJECTIVES: Robotic-assisted thoracic surgery (RATS) is increasingly used in our specialty. We surveyed European Society of Thoracic Surgeons membership with the objective to determine current status of robotic thoracic surgery practice including training perspectives. METHODS: A survey of 17 questions was rolled out with 1 surgeon per unit responses considered as acceptable. RESULTS: A total of 174 responses were obtained; 56% (97) were board-certified thoracic surgeons; 28% (49) were unit heads. Most responses came from Italy (20); 22% (38) had no robot in their institutions, 31% (54) had limited access and only 17% (30) had full access including proctoring. Da Vinci Xi was the commonest system in 56% (96) centres, 25% (41) of them had dual console in all systems, whereas RATS simulator was available only in half (51.18% or 87). Video-assisted thoracic surgery (VATS) was the most commonly adopted surgical approach in 81% of centres (139), followed by thoracotomy in 67% (115) and RATS in 36% (62); 39% spent their training time on robotic simulator for training, 51% on robotic wet/dry lab, which being no significantly different to 46-59% who had training on VATS platform. There was indeed huge overlap between simulator models or varieties usage; 52% (90) reported of robotic surgery not a part of training curriculum with no plans to introduce it in future. Overall, 51.5% (89) responded of VATS experience being helpful in robotic training in view of familiarity with minimally invasive surgery anatomical views and dissection; 71% (124) reported that future thoracic surgeons should be proficient in both VATS and RATS. Half of the respondents found no difference in earlier chest drain removal with either approach (90), 35% (60) reported no difference in postoperative pain and 49% (84) found no difference in hospital stay; 52% (90) observed better lymph node harvest by RATS. CONCLUSIONS: Survey concluded on a positive response with at least 71% (123) surgeons recommending to adopt robotics in future.

Is vacuum-assisted closure therapy the main culprit in right ventricular rupture after deep sternal wound infection?

Right ventricular rupture after deep sternal wound infection (DSWI) is a rare but fatal complication, and can occur with or without vacuum assisted closure (VAC) therapy. There is currently no strong evidence to suggest whether or not VAC therapy is a contributing factor to this complication. In total, 30 articles were retrieved and assessed through a systematic review strategy from 1953 to 2022. The keywords: 'vacuum assisted closure'; 'VAC'; 'negative pressure wound therapy'; 'deep sternal wound infection'; 'DSWI'; 'right ventricular rupture'; and 'cardiac rupture' were used in the search. Overall, 15 of the included articles satisfied the predefined eligibility criteria. Fatal right ventricular ruptures were reported in 18 (36%) out of 50 cases. In this article, the risk factors, mechanisms and management of right ventricular rupture are discussed. A novel view of the mechanism of VAC-associated right ventricular rupture is highlighted, with a focus on both pre- and intraoperative management.

The transition to uniportal robotic surgery in the second decade of uniportal surgery.

Uniportal robotic surgery was created by Dr. Diego Gonzalez-Rivas as a fusion of his decade of experience with uniportal video-assisted thoracoscopic surgery (VATS) and his recent experience with the Intuitive Robotic System. It represents, in his view, the natural evolution of the uniportal technique in the era of robotic surgery. In this article, we discuss some of the novel issues that this raises, including capacitive coupling, and we describe the technique in detail to help surgeons who may be interested in starting uniportal robotic surgery. We go through case selection, which should start with wedge resections and lymphadenectomy. We look at port placement, which is more posterior and lower than the usual uniportal VATS approach, and we discuss the optimal instruments and ports for the technique. We discuss the role of the assistant in uniportal robotic surgery, which is a key part of the operation as we regard this as a two-surgeon technique. We then discuss the future and other possible robotic platforms that might be suitable for uniportal robotic surgery. It is an exciting new development for robotic surgery, and we recommend that this technique is suitable for advanced surgeons who are experienced in uniportal VATS lobectomy and in multiportal robotic surgery.

Video atlas of each uniportal robotic-assisted thoracic surgery lobectomy and lymphadenectomy.

It is important when evaluating new techniques that a surgeon can see and assess all the differences and similarities between their usual technique and the novel technique. Thus, we have collated a comprehensive atlas of videos of uniportal robotic lobectomies for every lobe. Surgeons who are considering embarking on a program of uniportal robotic lobectomies can accordingly see the different views and techniques that will be required for when they perform their first procedure. We have fully narrated the videos, so that you will be taken through each procedure. Whilst these five videos are fifty-five minutes in total, our intention is not necessarily for you to watch them all from start to finish, but rather, come to this video, select the lobe that you will shortly embark on, and watch it prior to your case so that you can visualise, as closely as possible, the procedure that you will be performing. We recommend that you watch the videos with your bedside assistant as the uniportal robotic lobectomy is a joint procedure between two surgeons, rather than a single surgeon's operation with an assistant. Though we have not provided videos on segmentectomies, the uniportal robotic lobectomy is an advanced technique and we are confident that advanced surgeons will be able to gain key insights with what has been included, even if they are proceeding to a segmentectomy for their first cases. We feel for an advanced surgeon, a segmentectomy will be just as suitable an operation as a lobectomy in the initial learning phase.

Comparison of uniportal robotic-assisted thoracic surgery pulmonary anatomic resections with multiport robotic-assisted thoracic surgery: a multicenter study of the European experience.

Background: Robotic-assisted thoracic surgery (RATS) has seen increasing interest in the last few years, with most procedures primarily being performed in the conventional multiport manner. Our team has developed a new approach that has the potential to convert surgeons from uniportal video-assisted thoracic surgery (VATS) or open surgery to robotic-assisted surgery, uniportal-RATS (U-RATS). We aimed to evaluate the outcomes of one single incision, uniportal robotic-assisted thoracic surgery (U-RATS) against standard multiport RATS (M-RATS) with regards to safety, feasibility, surgical technique, immediate oncological result, postoperative recovery, and 30-day follow-up morbidity and mortality. Methods: We performed a large retrospective multi-institutional review of our prospectively curated database, including 101 consecutive U-RATS procedures performed from September 2021 to October 2022, in the European centers that our main surgeon operates in. We compared these cases to 101 consecutive M-RATS cases done by our colleagues in Barcelona between 2019 to 2022. Results: Both patient groups were similar with respect to demographics, smoking status and tumor size, but were significantly younger in the U-RATS group [M-RATS =69 (range, 39-81) years; U-RATS =63 years (range, 19-82) years; P<0.0001]. Most patients in both operative groups underwent resection of a primary non-small cell lung cancer (NSCLC) [M-RATS 96/101 (95%); U-RATS =60/101 (59%); P<0.0001]. The main type of anatomic resection was lobectomy for the multiport group, and segmentectomy for the U-RATS group. In the M-RATS group, only one anatomical segmentectomy was performed, while the U-RATS group had twenty-four (24%) segmentectomies (P=0.0006). All M-RATS and U-RATS surgical specimens had negative resection margins (R0) and contained an equivalent median number of lymph nodes available for pathologic analysis [M-RATS =11 (range, 5-54); U-RATS =15 (range, 0-41); P=0.87]. Conversion rate to thoracotomy was zero in the U-RATS group and low in M-RATS [M-RATS =2/101 (2%); U-RATS =0/101; P=0.19]. Median operative time was also statistically different [M-RATS =150 (range, 60-300) minutes; U-RATS =136 (range, 30-308) minutes; P=0.0001]. Median length of stay was significantly lower in U-RATS group at four days [M-RATS =5 (range, 2-31) days; U-RATS =4 (range, 1-18) days; P<0.0001]. Rate of complications and 30-day mortality was low in both groups. Conclusions: U-RATS is feasible and safe for anatomic lung resections and comparable to the multiport conventional approach regarding surgical outcomes. Given the similarity of the technique to uniportal VATS, it presents the potential to convert minimally invasive thoracic surgeons to a robotic-assisted approach.

Safe Implementation of a Next-Generation Surgical Robot: First Analysis of 2,083 Cases in the Versius Surgical Registry.

OBJECTIVE: To present the first report of data from the Versius Surgical Registry, a prospective, multicenter data registry with ongoing collection across numerous surgical indications, developed to accompany the Versius Robotic Surgical System into clinical practice. BACKGROUND: A data registry can be utilized to minimize risk to patients by establishing the safety and effectiveness of innovative medical devices and generating a thorough evidence base of real-world data. METHODS: Surgical outcome data were collected and inputted through a secure online platform. Preoperative data included patient age, sex, body mass index, surgical history, and planned procedures. Intraoperative data included operative time, complications during surgery, conversion from robot-assisted surgery to an alternative surgical technique, and blood loss. Postoperative outcome data included length of hospital stay, complications following surgery, serious adverse events, return to the operating room, readmission to the hospital, and mortality within 90 days of surgery. RESULTS: This registry analysis included 2083 cases spanning general, colorectal, hernia, gynecologic, urological, and thoracic indications. A considerable number of cases were recorded for cholecystectomy (n=539), anterior resection (n=162), and total laparoscopic hysterocolpectomy (n=324) procedures. The rates of conversion to an alternative technique, serious adverse events, and 90-day mortality were low for all procedures across all surgical indications. CONCLUSIONS: We report the large-scale analysis of the first 2083 cases recorded in this surgical registry, with substantial data collected for cholecystectomies, anterior resections, and total laparoscopic hysterectomies. The extensive surgical outcome data reported here provide real-world evidence for the safe implementation of the surgical robot into clinical practice.

Safe implementation of surgical innovation: a prospective registry of the Versius Robotic Surgical System.

Objectives: To describe a new, international, prospective surgical registry developed to accompany the clinical implementation of the Versius Robotic Surgical System by accumulating real-world evidence of its safety and effectiveness. Interventions: This robotic surgical system was introduced in 2019 for its first live-human case. With its introduction, cumulative database enrollment was initiated across several surgical specialties, with systematic data collection via a secure online platform. Main outcome measures: Pre-operative data include diagnosis, planned procedure(s), characteristics (age, sex, body mass index and disease status) and surgical history. Peri-operative data include operative time, intra-operative blood loss and use of blood transfusion products, intra-operative complications, conversion to an alternative technique, return to the operating room prior to discharge and length of hospital stay. Complications and mortality within 90 days of surgery are also recorded. Results: The data collected in the registry are analyzed as comparative performance metrics, by meta-analyses or by individual surgeon performance using control method analysis. Continual monitoring of key performance indicators, using various types of analyses and outputs within the registry, have provided meaningful insights that help institutions, teams and individual surgeons to perform most effectively and ensure optimal patient safety. Conclusions: Harnessing the power of large-scale, real-world registry data for routine surveillance of device performance in live-human surgery from first use will enhance the safety and efficacy outcomes of innovative surgical techniques. Data are crucial to driving the evolution of robot-assisted minimal access surgery while minimizing risk to patients. Trial registration number: CTRI/2019/02/017872.

Uniportal fully robotic-assisted major pulmonary resections.

Robotic-assisted thoracoscopic surgery (RATS) has proven advantages over that of conventional thoracic surgery, primarily by offering a three-dimensional view and excellent maneuverability, and by providing great ergonomic comfort to the surgeon. The instrumentation specifically offers seven degrees of freedom, allowing for safe, yet complex dissections and radical lymphadenectomies. However, the robotic platform was initially designed with four robotic arms in mind, and therefore four to five incisions were needed for most thoracic approaches. The uniportal video-assisted thoracoscopic surgery (UVATS) approach, the philosophical predecessor to the uniportal robotic-assisted thoracoscopic surgery (URATS) approach, evolved very quickly with the help of the latest technologies during the last decade. Since the first cases of UVATS in 2010, we have improved upon the technique, such that we are now able to do increasingly more complex cases. This is due to the acquired experience, specifically designed instruments, better high-definition cameras and more angulated staplers. In our efforts to improve and adapt robotic surgery to the uniportal approach, we utilized the initial available platforms (Davinci Si and X) to test the feasibility of this approach, in terms of safety and possibilities. The latest platform, the Da Vinci Xi, due to the configuration of its arms, did indeed allow for us to reduce the number of incisions to two initially and finally to one. We hence decided to fully adapt the Da Vinci Xi® to allow for the URATS approach routinely, and performed the first fully robotic anatomic resections in the world in September 2021, in Coruña, Spain. We define pure or fully robotic URATS as robotic thoracic surgery performed by a single intercostal incision, without rib spreading, using the robotic camera, robotic dissecting instruments and robotic staplers.

Impact of video-assisted thoracoscopic lobectomy versus open lobectomy for lung cancer on recovery assessed using self-reported physical function: VIOLET RCT.

BACKGROUND: Lung cancer is the leading cause of cancer death. Surgery remains the main method of managing early-stage disease. Minimal-access video-assisted thoracoscopic surgery results in less tissue trauma than open surgery; however, it is not known if it improves patient outcomes. OBJECTIVE: To compare the clinical effectiveness and cost-effectiveness of video-assisted thoracoscopic surgery lobectomy with open surgery for the treatment of lung cancer. DESIGN, SETTING AND PARTICIPANTS: A multicentre, superiority, parallel-group, randomised controlled trial with blinding of participants (until hospital discharge) and outcome assessors conducted in nine NHS hospitals. Adults referred for lung resection for known or suspected lung cancer, with disease suitable for both surgeries, were eligible. Participants were followed up for 1 year. INTERVENTIONS: Participants were randomised 1 : 1 to video-assisted thoracoscopic surgery lobectomy or open surgery. Video-assisted thoracoscopic surgery used one to four keyhole incisions without rib spreading. Open surgery used a single incision with rib spreading, with or without rib resection. MAIN OUTCOME MEASURES: The primary outcome was self-reported physical function (using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30) at 5 weeks. Secondary outcomes included upstaging to pathologic node stage 2 disease, time from surgery to hospital discharge, pain in the first 2 days, prolonged pain requiring analgesia at > 5 weeks, adverse health events, uptake of adjuvant treatment, overall and disease-free survival, quality of life (Quality of Life Questionnaire Core 30, Quality of Life Questionnaire Lung Cancer 13 and EQ-5D) at 2 and 5 weeks and 3, 6 and 12 months, and cost-effectiveness. RESULTS: A total of 503 patients were randomised between July 2015 and February 2019 (video-assisted thoracoscopic surgery, n = 247; open surgery, n = 256). One participant withdrew before surgery. The mean age of patients was 69 years; 249 (49.5%) patients were men and 242 (48.1%) did not have a confirmed diagnosis. Lobectomy was performed in 453 of 502 (90.2%) participants and complete resection was achieved in 429 of 439 (97.7%) participants. Quality of Life Questionnaire Core 30 physical function was better in the video-assisted thoracoscopic surgery group than in the open-surgery group at 5 weeks (video-assisted thoracoscopic surgery, n = 247; open surgery, n = 255; mean difference 4.65, 95% confidence interval 1.69 to 7.61; p = 0.0089). Upstaging from clinical node stage 0 to pathologic node stage 1 and from clinical node stage 0 or 1 to pathologic node stage 2 was similar (p ≥ 0.50). Pain scores were similar on day 1, but lower in the video-assisted thoracoscopic surgery group on day 2 (mean difference -0.54, 95% confidence interval -0.99 to -0.09; p = 0.018). Analgesic consumption was 10% lower (95% CI -20% to 1%) and the median hospital stay was less (4 vs. 5 days, hazard ratio 1.34, 95% confidence interval 1.09, 1.65; p = 0.006) in the video-assisted thoracoscopic surgery group than in the open-surgery group. Prolonged pain was also less (relative risk 0.82, 95% confidence interval 0.72 to 0.94; p = 0.003). Time to uptake of adjuvant treatment, overall survival and progression-free survival were similar (p ≥ 0.28). Fewer participants in the video-assisted thoracoscopic surgery group than in the open-surgery group experienced complications before and after discharge from hospital (relative risk 0.74, 95% confidence interval 0.66 to 0.84; p < 0.001 and relative risk 0.81, 95% confidence interval 0.66 to 1.00; p = 0.053, respectively). Quality of life to 1 year was better across several domains in the video-assisted thoracoscopic surgery group than in the open-surgery group. The probability that video-assisted thoracoscopic surgery is cost-effective at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year is 1. LIMITATIONS: Ethnic minorities were under-represented compared with the UK population (< 5%), but the cohort reflected the lung cancer population. CONCLUSIONS: Video-assisted thoracoscopic surgery lobectomy was associated with less pain, fewer complications and better quality of life without any compromise to oncologic outcome. Use of video-assisted thoracoscopic surgery is highly likely to be cost-effective for the NHS. FUTURE WORK: Evaluation of the efficacy of video-assisted thoracoscopic surgery with robotic assistance, which is being offered in many hospitals. TRIAL REGISTRATION: This trial is registered as ISRCTN13472721. FUNDING: This project was funded by the National Institute for Health and Care Research ( NIHR ) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 48. See the NIHR Journals Library website for further project information.

BACKGROUND: Lung cancer is a common cause of cancer death worldwide. If the disease is caught early, the part of the lung containing the tumour can be removed in an operation called a lobectomy. The operation can be carried out through a large cut so that the surgeon has a full view of the lung, which is called open surgery, or using several small cuts and a camera, which is called video-assisted thoracoscopic (keyhole) surgery. It is thought that, as keyhole surgery is less invasive, patients recover quicker. However, to the best of our knowledge, there are no high-quality research studies that are applicable to UK practice to support this. This study was conducted so that it could be determined, based on high-quality evidence, which operation provides the best treatment and recovery for patients. WHO PARTICIPATED?: Five hundred and three adults referred for lobectomy for known or suspected lung cancer from nine hospitals in the UK. WHAT WAS INVOLVED?: Participants were randomly allocated to either receive keyhole or open surgery. Participants were followed up for 12 months. We collected information on further treatment, hospital visits, safety information and disease progression over this period. Participants were also asked to complete questionnaires about their health and recovery. WHAT DID THE TRIAL FIND?: For patients with early-stage lung cancer who underwent a lobectomy, keyhole surgery led to less pain, less time in hospital and better quality of life than open surgery, without having a detrimental effect on cancer progression or survival. Keyhole surgery was found to be cost-effective and to provide excellent value for money for the NHS.

Early effect of the COVID-19 pandemic on the North American cardiothoracic surgery job market.

Background: The present study aims to report the early effect of the coronavirus disease 2019 (COVID-19) pandemic on the cardiothoracic surgery job market in North America. Methods: The Cardiothoracic Surgery Network (CTSNet) job market database was queried, and patterns from January to May for 2019 versus January to May 2020 were compared for trends in job postings and job seekers. Results: Our study is comprised of 395 cardiothoracic surgery job postings, of which 98% were positions located in North America and 63% were academic. The negative impact of the pandemic on the cardiothoracic surgery job market was greatest in the cardiothoracic/cardiovascular combined subspecialty, followed by congenital and adult cardiac surgery, whereas general thoracic surgery experienced an increase in proportion of jobs available. Despite an increase in views per job posted in 2020 vs. 2019 (532 vs. 290), employer views of job seeker curriculum vitae declined over the same time period in 2020 (January, 380 views/month to May, 3 views/month) compared to 2019 (January, 100 views/month to May, 54 views/month). Conclusions: An analysis of job postings from CTSNet suggests a decline in job availability in the North American cardiothoracic surgical job market following declaration of the pandemic with acknowledgement that there is month to month variability and a supply-demand mismatch. The COVID-19 pandemic has had an unprecedented impact on our field, and the ultimate consequences remain unknown.

Joint British Societies' guideline on management of cardiac arrest in the cardiac catheter laboratory.

More than 300 000 procedures are performed in cardiac catheter laboratories in the UK each year. The variety and complexity of percutaneous cardiovascular procedures have both increased substantially since the early days of invasive cardiology, when it was largely focused on elective coronary angiography and single chamber (right ventricular) permanent pacemaker implantation. Modern-day invasive cardiology encompasses primary percutaneous coronary intervention, cardiac resynchronisation therapy, complex arrhythmia ablation and structural heart interventions. These procedures all carry the risk of cardiac arrest.We have developed evidence-based guidelines for the management of cardiac arrest in adult patients in the catheter laboratory. The guidelines include recommendations which were developed by collaboration between nine professional and patient societies that are involved in promoting high-quality care for patients with cardiovascular conditions. We present a set of protocols which use the skills of the whole catheter laboratory team and which are aimed at achieving the best possible outcomes for patients who suffer a cardiac arrest in this setting. We identified six roles and developed a treatment algorithm which should be adopted during cardiac arrest in the catheter laboratory. We recommend that all catheter laboratory staff undergo regular training for these emergency situations which they will inevitably face.

Preclinical evaluation of Versius, an innovative device for use in robot-assisted thoracic surgery.

OBJECTIVES: The adoption of robot-assisted thoracic surgery (RATS) has helped to overcome some of the challenges associated with surgeons performing conventional video-assisted thoracic surgery. The Versius Surgical System (CMR Surgical, Cambridge, UK) has been developed iteratively in line with surgical team feedback to improve the surgeon's experience and patient outcomes. The goal of this study was to assess the use of the device in RATS in a preclinical setting and to fulfil Idea, Development, Exploration, Assessment, Long-Term Follow Up-Devices stage 1 (Idea). METHODS: Four cadaveric sessions were conducted between November 2018 and December 2020, during which device performance in a range of thoracic operations was assessed. Procedures were categorized as either completed or not completed, and surgeons evaluated the device's ability to successfully complete necessary surgical steps. Port and bedside unit positions were recorded. RESULTS: In total, 22/24 (91.7%) thoracic procedures were successfully completed, including 17/18 lobectomies, 2/3 thymectomies and 3/3 diaphragm plications, in 9 cadaver specimens. One thymectomy could not be completed due to cadaver anatomy and 1 lobectomy was not completed due a console system fault. Port and bedside unit configurations were successfully validated for all procedures, and lead surgeons deemed the device to be well-suited for thoracic surgery. CONCLUSIONS: This preclinical study demonstrated the successful use of the device in RATS in cadaveric models and supports progression to small-scale clinical studies, as part of Idea, Development, Exploration, Assessment, Long-Term Follow Up-Devices stage 2a (Development).

Video-Assisted Thoracoscopic or Open Lobectomy in Early-Stage Lung Cancer.

Video-Assisted Thoracoscopic Surgery or Open Lobectomy in Early-Stage Lung CancerIn a patient with early-stage lung cancer, is resection by video-assisted thoracoscopic surgery (VATS) versus open resection superior with respect to the postoperative recovery? This question was addressed in a multicenter randomized trial in more than 500 patients. At 5 weeks after surgery, the physical function mean score was 73 in the VATS group and 67 in the open surgery group (function scores range from 0 to 100, with higher scores indicating better function). Of the participants allocated to VATS, 30.7% had serious adverse events after discharge compared with 37.8% of those allocated to open surgery. At 52 weeks, there were no differences in cancer progression-free survival.

Investigating balance, gait, and physical function in people who have undergone thoracic surgery for a diagnosis of lung cancer: A mixed-methods study.

OBJECTIVES: Symptoms associated with lung cancer and thoracic surgery might increase fall risk. We aimed to investigate: 1) balance, gait and functional status in people post-thoracic surgery compared to healthy controls; 2) perceptions of balance, gait and functional status. METHODS: Recruitment targeted older adults (≥50 years) who had undergone thoracic surgery for a diagnosis of lung cancer in the previous 3 months, and healthy age-matched controls. Dynamic and static balance, gait velocity, knee-extension strength and physical activity levels were assessed using the BESTest, Kistler force plate, GAITRite system, Biodex System 3 and CHAMPS questionnaire, respectively. Two-part semi-structured interviews were conducted post-surgery. RESULTS: Individuals post-surgery (n = 15) had worse dynamic balance and gait, and lower levels of moderate/vigorous physical activity (MVPA) (all p<0.05) versus healthy controls (n = 15). Strength did not differ between groups (p > 0.05). No associations between BESTest and strength or physical activity existed post-surgery (p > 0.05). Three themes were identified: 1) Symptoms affect daily activities; 2) Functional assessments alter perceptions of balance ability and 3) Open to supervised rehabilitation. CONCLUSION: Balance, gait and MVPA are impaired post-thoracic surgery, yet balance was not viewed to be important in enabling activities of daily living. However, supervised rehabilitation was considered acceptable.

Minimally Invasive Plication of the Diaphragm: A Single-Center Prospective Study.

OBJECTIVE: Plication of the diaphragm is a life-changing procedure for patients affected by diaphragm paralysis. Traditionally, this procedure is performed through a thoracotomy. Access to the diaphragm via this incision is poor and the indications for surgery are limited to patients who can actually sustain such an invasive approach and associated morbidities. A minimally invasive approach was developed to improve the surgical management of diaphragm paralysis. METHODS: Patients underwent minimally invasive diaphragm plication either by video-assisted or robotic surgery through a 3-port technique with CO2 insufflation. Patients were followed at the routine 6-week clinic and also by telephone consultation 6 to 12 months postoperatively. Data were collected on postoperative complications, postoperative pain or numbness, symptomatic improvement, and change to quality of life following surgery. RESULTS: Forty-eight patients underwent 49 minimally invasive diaphragm plication. Median postoperative length of hospital stay was 4 days (range: 2 to 34 days) and there were no cases of mortality. Mean reduction in Medical Research Council dyspnea score per patient was 2.2 points (mode: 3 points). Twenty-eight patients (77.8%) reported a significant symptomatic improvement enabling improvements in quality of life, and 97.2% (n = 35) were satisfied with the surgical outcome. CONCLUSIONS: Minimally invasive diaphragm plication is a safe procedure associated with prompt postoperative recovery. It is effective at reducing debilitating dyspnea and improving quality of life.
