Trends in the Treatment of Pectus Excavatum in the Netherlands.

INTRODUCTION: Pectus excavatum (PE) is the most common deformity of the anterior chest wall and can be corrected surgically with different techniques. In the past years, medical literature suggests that the minimal invasive surgical correction of PE (MIRPE) has currently become the operation technique of choice in Europe, and the number of PE patients undergoing surgery has increased. The aim of this study was to evaluate trends in the number of patients operated on and the surgical techniques generally used in patients with PE in the Netherlands. MATERIALS AND METHODS: From the registration by Statistics Netherlands, the numbers of live births and gender were obtained for the period 1980 to 2017. Furthermore, from the Dutch hospital registration performed by Kiwa Prismant systems, the number of total surgical procedures of PE patients from the period 1998 to 2017, and the numbers of open and MIRPE surgery were obtained over the period 2005 to 2013. RESULTS: The birth rate in Netherlands has stayed more or less stable in the last two decades. The number of PE patients asking for correction, however, has increased. In addition, the percentage of thoracoscopic assisted correction has increased. CONCLUSION: The increase in correction of PE is not due to an increased incidence but to an increase of patient wishes. The use of MIRPE is gaining popularity over time.

Clinical Experience with Thymic Cystectomy: A Single-Institution Study of 117 Cases from 2013 to 2019.

BACKGROUND The aim of this study was to summarize the clinical experience of thymic cysts treatment from a single center. MATERIAL AND METHODS Clinical data, imaging, pathological results, and follow-up results of thymic cyst patients who underwent surgery from January 2013 to September 2019 were retrospectively reviewed. RESULTS A total of 117 patients were enrolled, including 76 asymptomatic patients and 41 symptomatic patients. The average diameter of thymic cysts, the cysts in asymptomatic patients, and those in symptomatic patients were 31.93±19.92 mm, 29.28±17.97 mm, and 36.85±22.50 mm, respectively. The number of cysts ranged from 1 to 3 cm, 3 to 6 cm, and >6 cm in 73 cases (62.4%), 32 cases (27.3%), and 12 cases (10.3%), respectively. There was no correlation between the size of thymic cysts and the presence or absence of symptoms. Only 20 cases (17.1%) were correctly diagnosed as thymic cysts before surgery. There were 67 patients (57.3%) who underwent video-assisted thoracic surgery (VATS) and 50 cases (42.7%) underwent open surgery. Cystectomy was performed in 93 cases (79.5%) and 24 cases (20.5%) underwent simultaneous resection of thymic cysts and other thoracic tumors. Compared with the thoracotomy group, the VATS group had shorter hospital stay and chest tube indwelling time. No serious complications occurred after surgery. The median follow-up time was 45.0 months (range 4.0-84.0 months) and there was no recurrence. CONCLUSIONS Attention should be paid to the accuracy of preoperative diagnosis of thymic cysts and the reduction of asymptomatic thymic cystectomy. For patients who have both thymic cysts and other thoracic tumors, simultaneous surgery is safe and feasible.

Healthcare Costs and Utilization among Patients Hospitalized for Malignant Pleural Effusion.

BACKGROUND: Malignant pleural effusion (MPE) poses a considerable healthcare burden, but little is known about trends in directly attributable hospital utilization. OBJECTIVE: We aimed to study national trends in healthcare utilization and outcomes among hospitalized MPE patients. METHODS: We analyzed adult hospitalizations attributable to MPE using the Healthcare Cost and Utilization Project - National Inpatient Sample (HCUP-NIS) databases from 2004, 2009, and 2014. Cases were included if MPE was coded as the principal admission diagnosis or if unspecified pleural effusion was coded as the principal admission diagnosis in the setting of metastatic cancer. Annual hospitalizations were estimated for the entire US hospital population using discharge weights. Length of stay (LOS), hospital charges, and hospital mortality were also estimated. RESULTS: We analyzed 92,034 hospital discharges spanning a decade (2004-2014). Yearly hospitalizations steadily decreased from 38,865 to 23,965 during this time frame, the mean LOS decreased from 7.7 to 6.3 days, and the adjusted hospital mortality decreased from 7.9 to 4.5% (p = 0.00 for all trend analyses). The number of pleurodesis procedures also decreased over time (p = 0.00). The mean inflation-adjusted charge per hospitalization rose from USD 41,252 to USD 56,951, but fewer hospitalizations drove the total annual charges down from USD 1.51 billion to USD 1.37 billion (p = 0.00 for both analyses). CONCLUSIONS: The burden of hospital-based resource utilization associated with MPE has decreased over time, with a reduction in attributable hospitalizations by one third in the span of 1 decade. Correspondingly, the number of inpatient pleurodesis procedures has decreased during this time frame.

Interventional Pulmonology and COVID-19: Experience from a Malaysian Tertiary Hospital.

The ongoing pandemic of COVID-19 has presented multiple challenges to global healthcare services, dictating changes in almost every aspect of daily medical practice. Performing aerosol generating procedures (AGPs) in the field of interventional pulmonology can lead to profound formation of aerosols, leading to a high risk of infection among healthcare workers (HCWs). We share our experiences on performing AGPs in the midst of a COVID-19 pandemic by focusing on changes in AGP practices. In a pandemic, HCWs ought to adapt to the ever-changing situation and use available resources to provide the best possible healthcare to patients, ensure safety of staff, and continue medical education of future pulmonologists.

Radiofrequency in the treatment of primary hyperhidrosis: systematic review and meta-analysis.

PURPOSE: To evaluate, via a systematic review, the effectiveness of radiofrequency (RF) for treatment of primary hyperhidrosis (PH). METHODS: Experimental or observational studies were included where RF treatment (ablation or microneedling) was performed, comparing the periods before and after treatment. RESULTS: Nine studies were considered eligible and included for analysis. In seven of nine studies, patients were subjected to RF only, and in two of nine studies RF was compared to video-assisted thoracoscopic sympathectomy (VATS). There was a reduction in the severity of PH in microneedling (three studies, mean difference -1.24, 95% CI -1.44 to -1.03). In a study that performed sympathetic RF ablation there was a greater reduction in PH severity compared to studies that performed microneedling (-2.42, 95% CI -2.55 to -2.29). There was improvement in the quality of life (QoL) after sympathetic RF ablation (two studies, mean difference -15.92, 95% CI -17.61 to -14.24). Regarding the microneedling procedure, there was a lower improvement in QoL, (two studies, -9.0, 95% CI -9.15 to -8.85). One study comparing sympathetic RF ablation with VATS applied the QoL questionnaire, and the VATS showed superior results. One of the two studies comparing compensatory sweating in RF ablation with VATS showed that compensatory hyperhidrosis was higher in VATS; however, the other study did not observe this difference. One study compared the recurrence of symptoms between VATS and RF ablation; symptom recurrence was shown to be higher in RF. CONCLUSIONS: RF is effective for PH treatment, with superior results obtained with sympathetic ablation compared to microneedling.

Trends in the Incidence, Etiology, Treatment, and Outcomes of Pleural Infections in Adults Over a Decade in a Finnish University Hospital.

BACKGROUND AND AIMS: The aim of the study was to ascertain changes in the incidence, etiology, treatment, and outcomes of pleural infections over a decade in a Finnish University Hospital. MATERIALS AND METHODS: All patients treated for pleural infections in Tampere University Hospital during 2000-2008 and 2012-2016 were included. The incidence rates and the epidemiologic data and medical history of patients, etiology of infection, and treatment trends and outcomes were compared between the cohorts. RESULTS: The incidence of pleural infections increased from 4.4 during 2000-2008 to 9.9 during 2012-2016 per 100.000 patient-years, p < 0.001. The patients in the latter group were older, 63 versus 57 years, p = 0.001, and the prevalence of chronic lung disease, hypertension, heart failure, dyslipidemia, and immunosuppressive medication were higher. The causes of infection remained similar and pneumonia accounted for 70% of all cases. The identification rate of the microbe pathogens increased from 49% to 64%, p = 0.002, while the distribution of identified pathogens was unchanged. More patients in the latter cohort were treated operatively, 88.3% versus 80.9%, p = 0.005, and, in these, the proportion of thoracoscopic surgery was higher, 57.4% versus 8.0%, p < 0.001, and the delay to surgery shorter, 5 versus 7 days, p < 0.001. Radiologic outcomes were similar. The 30-day mortality rate was 3.1% during 2000-2008 and 5.1% during 2012-2016, p = 0.293. CONCLUSION: The overall incidence of pleural infections has increased significantly while the causes of pleural infections and the distribution of pathogens remain unchanged. Contemporary patients are older with higher prevalence of comorbidities and more frequently undergo thoracoscopic surgery.

Evolving changes of minimally invasive esophagectomy: a single-institution experience.

BACKGROUND: Initial adoption of minimally invasive esophagectomy (MIE) began in the late 1990s but its surgical technique, perioperative management, and outcome continues to evolve. METHODS: The aim of this study was to examine the evolving changes in the technique, outcome, and new strategies in management of postoperative leaks after MIE was performed at a single institution over a two-decade period. A retrospective chart review of 75 MIE operations was performed between November 2011 and September 2018 and this was compared to the initial series of 104 MIE operations performed by the same group between 1998 and 2007. Operative technique, outcomes, and management strategies of leaks were compared. RESULTS: There were 65 males (86.7%) with an average age of 61 years. The laparoscopic/thoracoscopic Ivor Lewis esophagectomy became the preferred MIE approach (49% of cases in the initial vs. 95% in the current series). Compared to the initial case series, there was no significant difference in median length of stay (8 vs. 8 days), major complications (12.5% vs. 14.7%, p = 0.68), incidence of leak (9.6% vs. 10.6%, p = 0.82), anastomotic stricture (26% vs. 32.0%, p = 0.38), or in-hospital mortality (2.9% vs. 2.6%, p = 0.47). Management of esophageal leaks has changed from primarily thoracotomy ± diversion initially (50% of leak cases) to endoscopic stenting ± laparoscopy/thoracoscopy currently (87.5% of leak cases). CONCLUSION: In a single-institutional series of MIE over two decades, there was a shift toward a preference for the laparoscopic/thoracoscopic Ivor Lewis approach with similar outcomes. The management of postoperative leaks drastically changed with predilection toward minimally invasive option with endoscopic drainage and stenting.

Geographical variance in reporting of elective surgery for chronic pancreatitis.

The selection of optimum surgical procedure from the range of reported operations for chronic pancreatitis (CP) can be difficult. The aim of this study is to explore geographical variation in reporting of elective surgery for CP. A systematic search of the literature was performed using the Scopus database for reports of five selected procedures for CP: duodenum-preserving pancreatic head resection, total pancreatectomy with islet autotransplantation (TPIAT), Frey pancreaticojejunostomy, thoracoscopic splanchnotomy and the Izbicki V-shaped resection. The keyword and MESH heading 'chronic pancreatitis' was used. Overall, 144 papers met inclusion criteria and were utilized for data extraction. There were 33 reports of duodenum-preserving pancreatic head resection. Twenty-one (64%) were from Germany. There were 60 reports of TPIAT, 53 (88%) from the USA. There are only two reports of TPIAT from outwith the USA and UK. The 34 reports of the Frey pancreaticojejunostomy originate from 12 countries. There were 20 reports of thoracoscopic splanchnotomy originating from nine countries. All three reports of the Izbicki 'V' procedure are from Germany. There is geographical variation in reporting of surgery for CP. There is a need for greater standardization in the selection and reporting of surgery for patients with painful CP.

Survey of Postoperative Regional Analgesia for Thoracoscopic Surgeries in Canada.

OBJECTIVES: To determine the preferences and perceptions regarding analgesic options for video-assisted thoracic surgery (VATS) among thoracic anesthesiologists in Canada. DESIGN: A cross-sectional survey of thoracic anesthesiologists with 30 multiple choice questions was e-mailed through an online survey tool called FluidSurveys was performed to members of the Canadian Anesthesiologists' Society. SETTING: A nationwide survey. PARTICIPANTS: Members of Canadian Anesthesiologists' Society who provide thoracic anesthesia INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Participant characteristics and outcomes are described using counts and percentages. The frequency of use of each technique for each surgical category is described in percentages and 95% confidence intervals. Based on the responses obtained from individual centers, approximately 469 anesthesiologists provided thoracic care in Canada at the time of the survey. The response rate to the survey was 19% (n = 89). Epidural analgesia was preferred by 93.42% (95% CI 85-98) for open surgeries compared with 41% (30-52) for VATS lobectomies. The difference was statistically significant-52% (37-67). Patient-controlled analgesia was preferred by 27% (19-39) for VATS lobectomies and 46% (35-57) for VATS minor resections. Only 14% preferred paravertebral block for any VATS surgeries. CONCLUSIONS: The use of analgesic techniques for VATS surgeries is variable and largely dictated by provider preferences. The majority still prefer epidural analgesia compared with paravertebral catheter (placed either by the anesthesiologist or surgeon). A broadly acceptable choice that is effective, safe, and technically less demanding requires comparative effectiveness studies and more uniform training for physicians.

Safety and Efficacy of Single-Stage versus 2-Stage Spinal Fusion via Posterior Instrumentation and Anterior Thoracoscopy: A Retrospective Matched-Pair Cohort Study with 247 Consecutive Patients.

OBJECTIVE: Posterior-anterior spondylodesis is often used to stabilize the spine in various pathologies. The anterior procedure is often performed via thoracoscopy. It is unclear whether the anterior procedure should be performed immediately after posterior instrumentation or after the patient has convalesced. This retrospective study compared perioperative safety and morbidity in 1-stage versus 2-stage posterior-anterior fusion surgery with a thoracoscopic anterior approach. METHODS: All consecutive patients who underwent surgery for posterior-anterior spinal stabilization from 2006 to 2013 were included. American Society of Anesthesiologists score, preoperative and postoperative laboratory values, operation duration, blood loss, intensive care unit stay, pain, postoperative hospital stay, perioperative complications, and preoperative and postoperative Eastern Cooperative Oncology Group and Frankel scores were assessed. A subset of the cohort was selected by propensity score matching to eliminate possible selection bias. RESULTS: There were 247 patients who underwent 1-stage (n = 104) or 2-stage (n = 143) stabilization with thoracoscopic fusion. Spinal pathologies were fracture, malignancy, pyogenic spondylodiscitis, degenerative spinal disorders, and failed previous surgery. One-stage and 2-stage procedures were similar in terms of preoperative, surgical, and postoperative variables, including complication rates, except that the 1-stage procedure was associated with greater pain 2 days after surgery and shorter hospital stay. The propensity score-matched cohort of 64 pairs yielded similar results with only 1-stage patients showing elevated visual analog scale score on postoperative day 2 (3.8 vs. 2.4, P = 0.043). CONCLUSIONS: One-stage stabilization was as safe as 2-stage stabilization and associated with shorter hospitalization. Greater pain after the 1-stage procedure, which resolved 30 days after surgery, reflects the fact that 2-stage patients already had pain relief when they underwent thoracoscopy.

Construyendo la historia de la cirugía endovascular / Creating the history of endovascular surgery

Se relata la aparición de la cirugía mínimamente invasiva y dentro de ella la técnicas endovasculares, en relación con la evolución sociocultural de las relaciones médico-paciente desde la era del llamado paternalismo médico hasta que una vez aparecidos los derechos humanos y los derechos de los enfermos, estos pasan a tener autonomía sobre su salud y la técnicas diagnósticas y terapéuticas que reciben. Finalmente se relata brevemente la historia de las técnicas endovasculares y se propone formalmente el nombre de Cirugía Endovascular para englobarlas y se hacen unas consideraciones finales sobre la actual tecnolatría hacia el desarrollo tecnológico que conllevan (AU)

The appearance of minimally invasive surgery, and within it, the endovascular techniques, in relation to the sociocultural evolution of the doctor-patient relationship from the era of the so-called medical paternalism that, once the human rights and the rights of the patients came on the scene, patients gained freedom as regards their health, diagnosis and therapeutic techniques they receive. Finally, the history of endovascular techniques is briefly described, and the name Endovascular Surgery is formally proposed to include these. Finally, some thoughts are expressed on the current technolatry and the technological developments they entail (AU)

Current trends in multimodality treatment of esophageal and gastroesophageal junction cancer - Review article.

PURPOSE: Multimodality treatment has now been widely introduced in the curatively intended treatment of esophageal and gastroesophageal junction cancer. We aim to give an overview of the scientific evidence for the available treatment strategies and to describe which trends that are currently developing. METHODS: We conducted a review of the scientific evidence for the different curatively intended treatment strategies that are available today. Relevant articles of randomized controlled trials, cohort studies, and meta analyses were included. RESULTS: After a systematic search of relevant papers we have included 64 articles in the review. The results show that adenocarcinomas and squamous cell carcinomas of the esophagus and gastroesophageal junction are two separate entities and should be analysed and studied as two different diseases. Neoadjuvant treatment followed by surgical resection is the gold standard of the curatively intended treatment today. There is no scientific evidence to support the use of chemoradiotherapy over chemotherapy in the neoadjuvant setting for esophageal or junctional adenocarcinoma. There is reasonable evidence to support definitive chemoradiotherapy as a treatment option for squamous cell carcinoma of the esophagus. CONCLUSION: The evidence base for curatively intended treatments of esophageal and gastroesophageal junction cancer is not very strong. Several on-going trials have the potential to change the gold standard treatments of today.

Nationwide Assessment of Robotic Lobectomy for Non-Small Cell Lung Cancer.

BACKGROUND: Robotic lobectomy has been described for non-small cell lung cancer (NSCLC). Our objectives were to (1) evaluate the use of robotic lobectomy over time, (2) identify factors associated with its use, and (3) assess outcomes after robotic lobectomy compared with other surgical approaches. METHODS: Stage I to IIIA NSCLC patients were identified from the National Cancer Data Base (2010 to 2012). Trends in robotic lobectomy were assessed over time, and multivariable logistic regression models were developed to identify factors associated with its use. Propensity-matched cohorts were constructed to compare postoperative outcomes after robotic lobectomy with thoracoscopic and open lobectomy. RESULTS: Lobectomy was performed in 62,206 patients by open (n = 45,527), thoracoscopic (n = 12,990), or robotic (n = 3,689) procedures at 1,215 hospitals. Between 2010 and 2012, robotic lobectomy significantly increased, from 3.0% to 9.1% (p < 0.001). Academic (odds ratio, 1.55; 95% confidence interval, 1.04 to 2.33) and high-volume hospitals (odds ratio, 1.49; 95% confidence interval, 1.04 to 2.14) were associated with increased use of robotic lobectomy. Length of stay was shorter in robotic lobectomy compared with open lobectomy (6.1 vs 6.9 days; p < 0.001). Fewer lymph nodes (9.9 vs 10.9; p < 0.001) and 12 or more nodes were examined less frequently (32.0% vs 35.6%; p = 0.005) in robotic resections than in thoracoscopic resections. There was no difference between robotic and open or robotic and thoracoscopic lobectomy patients in margin positivity, 30-day readmission, and deaths at 30 and 90 days. CONCLUSIONS: Robotic lobectomies have significantly increased in stage I to IIIA NSCLC patients, with outcomes similar to other approaches. Additional studies are needed to determine if this technology offers potential advantages compared with video-assisted thoracoscopic operations.

New trends in interventional pulmonology.

PURPOSE OF REVIEW: As the field of interventional pulmonology continues to expand and develop at a rapid pace, anesthesiologists are increasingly called upon to provide well tolerated anesthetic care during these procedures. These patients may not be candidates for surgical treatment and often have multiple comorbidities. It is important for anesthesiologists to familiarize themselves with these procedures and their associated risks and complications. RECENT FINDINGS: The scope of the interventional pulmonologist's practice is varied and includes both diagnostic and therapeutic procedures. Bronchial thermoplasty is now offered as endoscopic treatment of severe asthma. Endobronchial lung volume reduction procedures are currently undergoing clinical trials and may become more commonplace. Interventional pulmonologists are performing medical thoracoscopy for the treatment and diagnosis of pleural disorders. Interventional radiologists are performing complex pulmonary procedures, often requiring anesthesia. SUMMARY: The review summarizes the procedures now commonly performed by interventional pulmonologists and interventional radiologists. It discusses the anesthetic considerations for and common complications of these procedures to prepare anesthesiologists to safely care for these patients. Investigational techniques are also described.

Current trends in anesthesia for esophagectomy.

PURPOSE OF REVIEW: Despite marked improvements in perioperative outcomes, esophagectomy continues to be a high-risk operation associated with significant morbidity and mortality. Progress has been achieved through evidence-based changes in preoperative optimization, intraoperative ventilation strategies, fluid therapy, and analgesia, as well as expedited postoperative recovery pathways. This review will summarize the recent literature on the anesthetic management of patients undergoing esophageal resection. RECENT FINDINGS: The current focus in publications on the perioperative management of esophagectomy patients can be summarized under the umbrella term of enhanced recovery pathways, focusing on ventilation, fluid therapy, analgesia and minimally invasive surgical approaches. Lung protective ventilation reduces pulmonary complications in cases requiring one-lung ventilation. Excess fluid administration contributes to morbidity while restrictive approaches have not resulted in an increased risk of acute kidney injury. Goal-directed fluid therapy remains intuitive yet unproven. Thoracic epidural analgesia reduces the systemic inflammatory response, pulmonary complications, and enhances postoperative pain control, yet if causing perioperative hypotension may be associated with anastomotic leaks. Enhanced recovery pathways have facilitated low morbidity and mortality rates in a high-risk population but are heterogeneous and limited by a weak evidence base. Minimally invasive surgical approaches are increasingly popular and appear to have at least equivalent outcomes to open procedures. SUMMARY: The morbidity and mortality after esophagectomy remains high despite significant improvements over the last decades. Enhanced recovery pathways appear promising in achieving further marginal gains but at present are lacking large scale, prospective, multicenter evidence.
