The Evolution of Surgical Management for Children and Young Adults With Spontaneous Pneumothorax.

BACKGROUND: Few studies have analyzed pediatric spontaneous pneumothorax (SPTX) nationally. We sought to better define this patient population and explore the evolution of surgical management. METHODS: Patients (10-20 y old) with an International Classification of Diseases, Ninth Revision diagnosis of SPTX were identified within the Kids' Inpatient Database for the years 2006, 2009, and 2012. Diagnoses and procedures were analyzed by International Classification of Diseases, Ninth Revision codes. National estimates were obtained using case weighting. RESULTS: There were 11,792 pediatric SPTX hospitalizations, and patients were predominantly male (84.0%), non-Hispanic white (69.0%), with a mean age of 17.2 y (95% confidence interval, 17.2-17.3). Overall, 52.5% underwent tube thoracostomy as the primary intervention, and more than one-third had a major surgical procedure (34.9%). From 2006 to 2012, there was an increase in bleb excisions from 81.1% to 86.9% and an increase in mechanical pleurodesis from 64.2% to 69.0%. There was a significant change from a predominantly open thoracotomy approach in 2006 (76.1%) to a video-assisted thoracoscopic approach in 2012 (89.3%). CONCLUSIONS: Pediatric admission for SPTX results in tube thoracostomy in more than half of the cases and surgery in approximately one-third of the cases. Surgical intervention has changed to a more minimally invasive approach during the last decade, and counseling to patients and their families should reflect these updated management strategies. LEVEL OF EVIDENCE: III.

Evaluation of the Determinants of Satisfaction With Postoperative Pain Control After Thoracoscopic Surgery: A Single-Center, Survey-Based Study.

BACKGROUND: The need to measure, compare, and improve the quality of pain management is important to patients, payers, and health care providers. Pain after thoracic surgery can be severe, and thoracoscopic approaches have not had the favorable impact on pain as anticipated. The aim of this study was to evaluate the determinants of patient satisfaction with acute pain management and the effectiveness of pain control after video-assisted thoracoscopic surgery using a modified version of the Revised American Pain Society Patient Outcome Questionnaire. METHODS: We performed a single-center, prospective, survey-based study of 300 patients who had undergone elective video-assisted thoracoscopic surgery. Patients were enrolled and completed the survey on postoperative day 1 or 2. The primary outcome variable was patient-reported satisfaction with acute postoperative pain treatment measured on a 1-4 scale. The relationship between the items on the survey and patient satisfaction was analyzed to determine the factors significantly associated with satisfaction. RESULTS: Fifty-one percent of the patients had the highest satisfaction level with pain treatment, and 4% of the patients had the lowest satisfaction level. The mean reported acceptable pain level was 3.8 ± 1.9 (numeric rating scale [NRS], 0-10). The average pain intensity score at the time of the survey was 2.8 ± 2.1 (NRS, 0-10). The median for the most pain in the prior 24 hours was 7 (NRS, 0-10; interquartile range, 5-9). Five items from the survey were significantly associated with the satisfaction level. The predictor with the highest associated odds ratio (OR) with satisfaction was the ability to participate in pain management decisions (OR, 1.45; P < .0001). Another positively associated predictor was receiving helpful information about pain treatment options (OR, 1.31; P = .002). Negatively associated predictors of patient satisfaction included level of pain intensity at time of survey (OR, 0.76; P = .002), lowest pain score in the prior 24 hours (OR, 0.70; P = .0006), and having pain interfere with sleep in the postoperative period (OR, 0.72; P = .037). CONCLUSIONS: Our findings highlight several factors associated with patient satisfaction with acute postoperative pain management. Interventions focused on achieving acceptable pain levels for the majority of the time, ensuring that patients are able to get sleep, providing patients with helpful information about their pain treatment, and, most importantly, allowing patients to participate in decisions about their pain management may improve patient satisfaction with postoperative pain management.

Serial Observation of Blood Alcohol Concentration post Ethanol Pleurodesis (SOBER) Study: A Prospective Observational Study.

OBJECTIVES: To measure the blood alcohol concentration levels in patients after chemical pleurodesis with ethanol sclerosant via video-assisted thoracoscopic surgery. DESIGN: Prospective observational study. SETTING: Single tertiary university hospital. PARTICIPANTS: Eight patients undergoing chemical pleurodesis with ethanol sclerosant for management of recurrent pneumothoraces or pleural effusions. INTERVENTIONS: After ethics board approval, written informed consent was obtained from 8 patients undergoing chemical pleurodesis with ethanol sclerosant for management of recurrent pneumothoraces or pleural effusions. Five patients received a dose of 100 mL of 70% ethanol/1% iodine, and 3 patients received 30 mL. Blood alcohol concentration measurement was obtained at 30, 60, 90, and 120 minutes after the ethanol was instilled in the interpleural space. The postoperative quality of recovery scale was conducted preoperatively and then at 30 and 60 minutes postoperatively and on postoperative days 1 and 3. MEASUREMENTS AND MAIN RESULTS: The highest observed blood alcohol concentration was recorded at 30 minutes post-instillation of ethanol in all patients. The blood alcohol concentration peak for 75% of patients (6/8) was >0.05 g/dL at 30 minutes post-instillation of ethanol, and for 4 patients (50%), this remained >0.05 g/dL at 60 minutes. The median area under curve of ethanol absorbed was 5.66 g/dL/min (3.24-7.29). CONCLUSIONS: Significant systemic absorption of ethanol can occur after instillation of ethanol sclerosant, which potentially may affect the quality of recovery in patients. Postoperative management of these patients may need to be specifically tailored to take into account these observations.

Thirty-Day Unplanned Reintubation Following Pleurodesis: A Retrospective National Registry Analysis.

OBJECTIVE: To examine risk factors associated with 30-day unplanned reintubation after pleurodesis. DESIGN: A retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program surgical outcomes registry. SETTING: United States hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program. PARTICIPANTS: The study comprised 2,358 patients who underwent video-assisted thorascopic surgery for pleurodesis from 2007 to 2016. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The final sample included 2,358 cases, of which 93 (3.9%) required 30-day unplanned reintubation. Cases with 30-day unplanned reintubation, compared to those without, had higher unadjusted rates of American Society of Anesthesiologists physical status (ASA PS) score ≥4 (54.8% v 27.2%), preoperative dyspnea (71% v 57%), congestive heart failure (14% v 5.4%), functional dependence (28% v 10.3%), and diabetes mellitus (29% v 17.8%) (all p < 0.05). Patients with 30-day reintubation experienced higher unadjusted rates of 30-day outcomes including mortality (50.5% v 10.1%), pneumonia (28% v 4.9%), ventilator dependence (50.5% v 10.1%), sepsis (7.5% v 1.9%), myocardial infarction (5.4% v 0.1%), cardiac arrest (18.3% v 0.6%), transfusion (14% v 4.5%), and reoperation (15.1% v 3.2%) (all p < 0.05). The odds of 30-day unplanned reintubation were increased significantly on multivariable analysis for patients with ASA PS score ≥4, functional dependence, disseminated cancer, renal dialysis, and weight loss (all p < 0.05). CONCLUSION: Given the dearth of population-based studies addressing risk factors of reintubation after pleurodesis, this study suggests further review of preoperative optimization, which is required to improve patient outcomes and safety.

Trends in Hospital Treatment of Empyema in Children in the United States.

OBJECTIVE: To evaluate trends in procedures used to treat children hospitalized in the US with empyema during a period that included the release of guidelines endorsing chest tube placement as an acceptable first-line alternative to video-assisted thoracoscopic surgery. STUDY DESIGN: We used National Inpatient Samples to describe empyema-related discharges of children ages 0-17 years during 2008-2014. We evaluated trends using inverse variance weighted linear regression and characterized treatment failure using multivariable logistic regression to identify factors associated with having more than 1 procedure. RESULTS: Empyema-related discharges declined from 3 in 100 000 children to 2 in 100 000 during 2008-2014 (P = .04, linear trend). There was no significant change in the proportion of discharges having 1 procedure (66.1% to 64.1%) or in the proportion having 2 or more procedures (22.1% to 21.6%). The proportion coded for video-assisted thoracoscopic surgery as the only procedure declined (41.4% to 36.2%; P = .03), and the proportions coded for 1 chest tube (14.6% to 20.9%; P = .04) and 2 chest tube procedures (0.9% to 3.5%; P < .01) both increased. The median length of stay for empyema-related discharges remained unchanged (9.3 days to 9.8 days; P = .053). Having more than 1 procedure was associated with continuous mechanical ventilation (adjusted OR, 2.7; 95% CI, 1.8-4.1) but not with age, sex, payer, chronic conditions, transfer admission, hospital size, or census region. CONCLUSIONS: The use of video-assisted thoracoscopic surgery to treat children in the US hospitalized with empyema seems to be decreasing without associated increases in length of stay or need for additional drainage procedures.

Outcomes of video-assisted thoracoscopic surgery for transvenous lead extraction.

INTRODUCTION: To evaluate the outcomes of video-assisted thoracoscopic surgery (VATS) during transvenous lead extractions (TLEs). METHODS AND RESULTS: Ninety-one high-risk patients who underwent TLE in the operating room from January 1, 2015, to March 31, 2017, were included in the study. Of these, 9 patients underwent VATS during TLE. Their clinical characteristics, indications for lead extraction, and complications associated with TLE in the 9 patients who had VATS were compared with those for the 82 patients who did not have VATS. The mean (SD) age of the study patients was 61 (17) years (64.8% were male). The lead dwell time, number of leads extracted, and clinical comorbidities were similar between the 2 groups. Superior vena cava (SVC) tear occurred in 2 of the 9 patients in VATS group and in 1 of the 82 in the non-VATS group (22.2% vs. 1.2%, P = 0.03). Of the 2 patients in the VATS group who had SVC tears, in 1 the tear was visualized immediately and there was no hemodynamic compromise. In the other patient, the SVC tear was within the pericardium; the blood pressure recovered quickly after sternotomy and repair. Both patients had complete lead extraction and survived hospitalization. The patient in the non-VATS group who had an SVC tear had a successful repair but died of postoperative complications. CONCLUSIONS: Utilization of VATS to facilitate TLE is beneficial for early recognition of SVC tear and timely surgical repair in select high-risk patients.

Enhanced Recovery After Surgery (ERAS®) in thoracic surgical oncology.

Enhanced recovery after surgery (ERAS®) is a strategy that seeks to reduce patients' perioperative stress response, thereby reducing potential complications, decreasing hospital length of stay and enabling patients to return more quickly to their baseline functional status. The concept was introduced in the late 1990s and was first adopted for use with patients undergoing open colorectal surgery. Since that time, the concept of ERAS has spread to multiple surgical specialties. This article explores the key elements for patient care using an ERAS protocol applied to minimally invasive thoracic surgery.

Is it appropriate to perform video-assisted thoracoscopic surgery for advanced lung cancer?

Video-assisted thoracoscopic surgery (VATS) has showed benefits in terms of pain, hospital stay and accomplishment of adjuvancy therapy versus open surgery in early stage of non-small-cell lung cancer. Over the last years, the indication of VATS technique has been expanded to advanced lung cancer. In this article, we discuss the definition of VATS and advanced lung cancer, and the safety and feasibility of VATS technique for the resection of advanced tumors.

Tailored management of stage IIIa non-small-cell lung cancer in the era of the 8th edition of the TNM classification for lung cancer.

Stage IIIA is a very heterogeneous group encompassing locally advanced disease with T3 and T4 tumors without any nodal involvement and very small T1a primary tumors with unilateral mediastinal lymphatic disease. Tailored management defines interdisciplinary management requiring board decisions, which can sometimes be difficult particularly in stage IIIa non-small-cell lung cancer (NSCLC). Lobectomy still is standard of care even for stage I NSCLC, which increasingly is implemented using minimally invasive surgical technique. On the other hand even locally extended tumors are today safely resected with low morbidity and mortality. According to the 2015 guidelines of the European Society of Thoracic Surgeons any kind of anatomical lung resection for lung cancer with curative intent has to be accompanied by formal mediastinal lymph node dissection. The transcervical route for complete bilateral mediastinal lymphadenectomy offers improved completeness of resection without the need for single lung ventilation and ideally supports the concept of minimally invasive surgery.

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.

Postoperative Pyoderma Gangrenosum Following Video-Assisted Thoracic Surgery.

Pyoderma gangrenosum (PG) is a neutrophilic, ulcerative dermatosis that can develop at sites of cutaneous trauma, including surgical incisions, a phenomenon known as pathergy. The characteristic lesion is a painful, rapidly expanding ulceration with a violaceous undermined border.1 A biopsy taken from the expanding violaceous border shows predominantly neutrophilic dermal inflammation with neutrophilic abscess formation.

The etiology of PG appears to be variable among patients, as about a half of the reported cases are associated with systemic disease such as inflammatory bowel disease, rheumatoid arthritis, or myeloproliferative disorders, while the other half seem to be idiopathic.2 PG is difficult to diagnose as other etiologies, including infectious, vasculitic, and other inflammatory dermatoses, must be excluded.1 Histopathologic and biochemical markers of PG, such as dermal neutrophilic infiltrate or overexpression of interleukin-8,3 respectively, are not pathognomonic. Given that several drugs, such as hydralazine, mesalamine, and sunitinib, are reportedly associated with PG, failure to recognize this association and stop these medications may delay diagnosis and therapy. We report a case of idiopathic postoperative PG following video-assisted thoracic surgery (VATS).

Magnesium sulphate improves pulmonary function after video-assisted thoracoscopic surgery: A randomised double-blind placebo-controlled study.

BACKGROUND: Reduced lung volumes are unavoidable after lung resection surgery. Magnesium sulphate (MgSO4) administration has been reported to reduce the requirement for neuromuscular blocking drugs and postoperative analgesics in surgical patients. OBJECTIVE: To investigate the effect of MgSO4 on pulmonary function after video-assisted thoracoscopic surgery (VATS). DESIGN: A randomised, double-blind, placebo-controlled trial. SETTING: A university tertiary care centre. PATIENTS: Sixty-six patients scheduled for pulmonary lobectomy or segmentectomy via VATS. INTERVENTION: Patients were allocated to one of two groups: the Mg (MgSO4 50 mg kg intravenously for 10 min, followed by a continuous infusion of 15 mg kg h during surgery) or the control (same volume of 0.9% saline). MAIN OUTCOME MEASURES: Pulmonary function tests [forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and peak expiratory flow rate] were measured before surgery and at three time points after surgery (2, 24 and 48 h postoperatively) using a portable spirometer. Twelve months after surgery, pulmonary function test values were repeated at a regular outpatient follow-up visit. RESULTS: FEV1 at 24 (1.7 ±â€Š0.6 vs. 1.3 ±â€Š0.5 l, P = 0.033) and 48 h (1.7 ±â€Š0.6 vs. 1.4 ±â€Š0.5 l, P = 0.021) and FVC at 24 (2.0 ±â€Š0.8 vs. 1.6 ±â€Š0.6 l, P = 0.038) and 48 h (2.2 ±â€Š0.8 vs. 1.7 ±â€Š0.7 l, P = 0.008) after surgery were significantly greater in the Mg group. Patients in the Mg group required less rocuronium than those in the control group (64.2 ±â€Š19.9 vs. 74.9 ±â€Š20.3 mg, respectively; P = 0.041). Consumption of postoperative patient-controlled analgesia was also significantly less at 24 and 48 h after surgery in the Mg group (P = 0.022 and 0.015, respectively), although pain scores and rescue analgesics were comparable. Five patients in the control group were diagnosed with postoperative pneumonia using clinical and radiological criteria before discharge. FEV1 and FVC at 12 months after surgery were not different between the two groups. CONCLUSION: Intraoperative administration of MgSO4 improved pulmonary function and reduced the need for rocuronium and postoperative analgesics in patients who underwent VATS.

Surgical Treatment of Early l Stage Lung Cancer: What has Changed and What will Change in the Future.

Recent advances in the surgical treatment of early stage non-small cell lung cancer (NSCLC) have focused heavily on making procedures less invasive, less radical, and better tolerated. Advances in accuracy and increased utilization of cross-sectional imaging allows for diagnosis of smaller and more indolent tumors and preinvasive lesions. Similar to advanced disease, early-stage treatment is now being tailored to individual patients and their tumors. Sublobar resections are gaining acceptance as an oncologically equivalent approach to lobectomy in well-selected stage I patients. Minimally invasive approaches either by video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracic surgery are becoming the procedures of choice for anatomic NSCLC resections and provide decreased perioperative complications and increased tolerability, especially in the elderly and medically high-risk patients. Reports of even less invasive techniques including uniportal VATS and nonintubated lobar resections are now appearing in the literature.

Fast-track video-assisted thoracoscopic surgery: future challenges.

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.

Novel Techniques in Video-assisted Thoracic Surgery (VATS) Lobectomy.

Twenty years ago, thoracic surgery witnessed the leap from thoracotomy to the first video-assisted thoracic surgery (VATS) lobectomy. Gradually VATS lobectomy has become widely accepted and practiced worldwide. As the idea of less-invasive, fewer, and smaller incisions is taken up by surgeons, thoracic surgery has witnessed the progress of the conventional three-port VATS lung resection to two-port VATS and finally the birth of uniportal VATS lobectomy. Incisions have also become much smaller over the years, such as those seen in total port access lobectomy or microlobectomy. A modified version of the uniportal VATS lobectomy through the subxiphoid incision has also recently been used. The movement toward less-invasive surgery has no doubt driven the innovation of sophisticated instruments and technology to cope with the demanding need of working through a restricted incision. Reported outcomes and results of these new developments are encouraging.

VATS lobectomy, history, indication, contraindication and general techniques.

VATS lobectomy is a respected modality of anatomic lung resections nowadays. Video-assisted lobectomies without rib extractor fulfil all current requirements for minimally invasive lung resections. This type of an anatomic pulmonary resection with a targeted treatment of hilar structures doesn't traumatize the intercostal space by using rib retractor. Videothoracoscope serves to visualize the surgical field on the screen. Assisted VATS (aVATS) lobectomy is a procedure using 3-5 cm working incision. Fully endoscopic resection (VTS) or complete VATS lobectomy (cVATS) are operations performed only through ports, without working incision. The authors supplement the article with a videorecord of VATS lobectomy general technique (Fig. 4, Ref. 11).

Clinical outcome of parapneumonic empyema in children treated according to a standardized medical treatment.

UNLABELLED: Treatment of parapneumonic empyema (PE) consists of intravenous antibiotics and, in case of large effusions and persisting fever, pleural chest drain (±intrapleural fibrinolytics) or video-assisted surgical intervention. We standardized the treatment for PE in our tertiary care center choosing a first-step nonsurgical approach. The aim was to evaluate the need for surgery and to collect data on disease course, outcome, and microbiology. For all children treated for PE between 2006 and 2013, data were prospectively collected concerning treatment, length of stay, duration of fever, complications, and causative agent. Of 132 children treated for PE, 20 % needed surgical intervention. Analyzed per year, the need for surgery decreased from almost 40 % in 2007 to 0 % in 2010 again increasing to 40 % although this did not reach statistical significance (p = 0.115). Median duration of "in-hospital fever" was 5 days (IQR, 3-8). The duration of fever correlated with pleural LDH (r = 0.324; p = 0.002) and pleural glucose (r = -0.248; p = 0.021) and was inversely correlated with pleural pH (r = -0.249; p = 0.046). Based on pleural PCR data, 85 % of PE were caused by Streptococcus pneumoniae (40 % serotype 1). CONCLUSION: After introduction of a standardized primary medical approach (chest drain ± fibrinolysis) for PE in our institution, the need for surgical rescue interventions overall remained at 20 %, which is higher than in some other reports. Difference in microbiology or disease severity could not be proven.

[Current status of thoracoscopic surgery for thoracic and lumbar spine. Part 2: treatment of the thoracic disc hernia, spinal deformities, spinal tumors, infections and miscellaneous]. / Situación actual de la cirugía toracoscópica del raquis torácico y lumbar. Parte 2: Tratamiento de la hernia de disco torácica, de las deformidades, de la patología tumoral e infecciosa, y miscelánea.

INTRODUCTION: Thoracoscopic surgery or video-assisted thoracic surgery (VATS) of the thoracic and lumbar spine has evolved greatly since it appeared less than 20 years ago. It is currently used in a large number of processes and injuries. The aim of this article, in its two parts, is to review the current status of VATS of the thoracic and lumbar spine in its entire spectrum. DEVELOPMENT: After reviewing the current literature, we developed each of the large groups of indications where VATS takes place, one by one. This second part reviews and discusses the management, treatment and specific thoracoscopic technique in thoracic disc herniation, spinal deformities, tumour pathology, infections of the spine and other possible indications for VATS. CONCLUSIONS: Thoracoscopic surgery is in many cases an alternative to conventional open surgery. The transdiaphragmatic approach has made endoscopic treatment of many thoracolumbar junction processes possible, thus widening the spectrum of therapeutic indications. These include the treatment of spinal deformities, spinal tumours, infections and other pathological processes, as well as the reconstruction of injured spinal segments and decompression of the spinal canal if lesion placement is favourable to antero-lateral approach. Good clinical results of thoracoscopic surgery are supported by growing experience reflected in a large number of articles. The degree of complications in thoracoscopic surgery is comparable to open surgery, with benefits in regard to morbidity of the approach and subsequent patient recovery.

INTRODUCTION: Thoracoscopic surgery or video-assisted thoracic surgery (VATS) of the thoracic and lumbar spine has greatly evolved since it appeared less than 20 years ago. Nowadays, it is indicated in a large number of processes and injuries. The aim of this article, in its 2 parts, is to review the current status of VATS in treatment of the thoracic and lumbar spine in its entire spectrum. DEVELOPMENT: After reviewing the current literature, we develop each of the large groups of indications where VATS is used, one by one. This first part contains a description of general thoracoscopic surgical technique including the necessary prerequisites, transdiaphragmatic approach, techniques and instrumentation used in spine reconstruction, as well as a review of treatment and specific techniques in the management of spinal fractures.

The transdiaphragmatic approach has made endoscopic treatment of many thoracolumbar junction processes possible, thus widening the spectrum of therapeutic indications. These include the treatment of fractures and deformities, as well as the reconstruction of injured spinal segments and decompression of the spinal canal in any etiological processes if the lesion placement is favourable to antero-lateral approach. Good clinical results of thoracoscopic surgery are supported by the growing experience reflected in a large number of articles. The degree of complications in thoracoscopic surgery is comparable to open surgery, with benefits in morbidity of the approach and subsequent patient recovery.

[Characteristics of customized device for video-assisted thoracoscopic surgery].

Video-assisted thoracoscopic surgery (VATS) has been a mainstay in surgical interventions for an early staged lung cancer over a decade. VATS procedures are nowadays categorized into 2 groups. One is a modified open procedures through a mini-thoracotomy with customization of conventional instruments. The other is a port-access procedure with use of newly developed instruments for endoscopic surgery. The optimal device adapting for individual surgical manipulations should be selected to make a VATS procedure safer and more feasible. The sample extraction using a bag is a most important step when VATS is completed, because the rupture of bag can result in cancer cell contamination. More useful devices adapting either for mini-thoracotomy VATS or for port-access VATS, will be developed with advancement of medical technology.
