    Full Text Available Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13% following blunt injury and 20 (87% after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury.

    Primary or metastatic lung cancer or mediastinal tumours may at times involve the phrenic nerve and pericardium. To remove the pathology en bloc, the phrenic nerve must be resected. This results in phrenic nerve paralysis, which in turn reduces pulmonary function and quality of life. As a curative measure of this paralysis and thus a preventive measure against decreased pulmonary function and quality of life, we have performed immediate phrenic nerve reconstruction under complete video-assisted thoracic surgery, and with minimal additional stress to the patient. This study sought to ascertain the utility of this procedure from an evaluation of the cases experienced to date. We performed 6 cases of complete video-assisted thoracic surgery phrenic nerve reconstruction from October 2009 to December 2013 in patients who had undergone phrenic nerve resection or separation to remove tumours en bloc. In all cases, it was difficult to separate the phrenic nerve from the tumour. Reconstruction involved direct anastomosis in 3 cases and intercostal nerve interposition anastomosis in the remaining 3 cases. In the 6 patients (3 men, 3 women; mean age 50.8 years), we performed two right-sided and four left-sided procedures. The mean anastomosis time was 5.3 min for direct anastomosis and 35.3 min for intercostal nerve interposition anastomosis. Postoperative phrenic nerve function was measured on chest X-ray during inspiration and expiration. Direct anastomosis was effective in 2 of the 3 patients, and intercostal nerve interposition anastomosis was effective in all 3 patients. Diaphragm function was confirmed on X-ray to be improved in these 5 patients. Complete video-assisted thoracic surgery phrenic nerve reconstruction was effective for direct anastomosis as well as for intercostal nerve interposition anastomosis in a small sample of selected patients. The procedure shows promise for phrenic nerve reconstruction and further data should be accumulated over time. © The

    Full Text Available Background: The role of video-assisted Thoracoscopic Surgery (VATS is still being defined in the management of thoracic trauma. We report our trauma cases managed by VATS and review the role of VATS in the management of thoracic trauma. Materials and Methods: All the trauma patients who underwent VATS from 2000 to 2007 at Cedars-Sinai Medical Center were retrospectively studied. Results: Twenty-three trauma patients underwent 25 cases of VATS. The most common indication for VATS was retained haemothorax. Thoracotomy was avoided in 21 patients. VATS failed in two cases. On an average VATS was performed on trauma day seven (range 1-26 and the length of hospital stay was 20 days (range 3-58. There was no mortality. VATS was performed in an emergency (day 1-2, or in the early (day 2-7 or late (after day 7 phases of trauma. Conclusion: VATS can be performed safely for the management of thoracic traumas. VATS can be performed before or after thoracotomy and at any stage of trauma. The use of VATS in trauma has a trimodal distribution (emergent, early, late, each with different indications.

    Video-assisted thoracic surgery (VATS) emerged as a minimally invasive surgery for diseases in the field of thoracic surgery. We herein reviewed our experience on thoracoscopic lobectomy for early lung cancer and evaluated Health System use. A cost-effectiveness study was performed comparing VATS vs. open thoracic surgery (OPEN) for lung cancer patients. Demographic data, tumor localization, dynamic pulmonary function tests [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), diffusion capacity (DLCO) and maximal oxygen uptake (VO2max)], surgical approach, postoperative details, and complications were recorded and analyzed. One hundred seventeen patients underwent lung resection by VATS (n=42, 36%; age: 63±9 years old, 57% males) or OPEN (n=75, 64%; age: 61±11 years old, 73% males). Pulmonary function tests decreased just after surgery with a parallel increasing tendency during first 12 months. VATS group tended to recover FEV1 and FVC quicker with significantly less clinical and post-surgical complications (31% vs. 53%, P=0.015). Costs including surgery and associated hospital stay, complications and costs in the 12 months after surgery were significantly lower for VATS (P<0.05). The VATS approach surgery allowed earlier recovery at a lower cost than OPEN with a better cost-effectiveness profile.

    Recent publications from North America have shown the benefits of robot-assisted thoracic surgery. We report here the process of setting up such a program in a French university centre and early results in a unit with an average treatment volume. Retrospective review of a single institution database. The program was launched after a 6-month preparation period. From January 2012 to January 2013, totally endoscopic, full robot-assisted procedures were performed on 30 patients (17 males). Median age was 54 [Q1-Q3, 48-63] years and ASA score 2 [1,2]. Operative procedures included thymectomy (9 ; 30%), lobectomy with nodes resection (11 ; 38%), segmentectomy (4 ; 14%), lymphadenectomy (3 ; 10%), Bronchogenic cyst (2, 5%) and posterior mediastinal mass resection (1 ; 3%). No conversion was required. Median blood loss was 50mL [10-100]. Median operating time was 135 min (105-165) including 30 min [20-40] for docking, 90min for robot-assisted operating [70-120] and 15 min [10-15] for lesion extraction. CO2 insufflation was used in 28 cases (93%). Hospital stay was 4 days [4-6] with 6 minor complications (20%) (Grade 1 according to the Clavien-Dindo classification). After a median 4 months follow-up [2-7], all patients were alive and demonstrated a good quality of life. This series suggests that full robotic thoracic procedures are safe and effective treatment for various pathologies, with low morbidity and without a significant learning curve, even in a lower volume centre. This technology should accompany the development of minimally invasive thoracic surgery. The importance of robotic training should be emphasized to optimize procedures and costs.

    The uniportal-video assisted thoracic surgery (VATS) technique comprises operations which can be performed with skin incisions ranging from 2 to 8 cm and the manifest result of the introduction of the uniportal lobectomy had made possible to increase rapidly the number of published papers on this subject. Many of the large ensuing literature report incomplete historical information on uniportal VATS, and doubts exist about the indication of uniportal VATS for some thoracic oncologic pathologies. Known limitations have been overcome. On the other hand, the modern thoracic surgical team includes one surgeon, one assistant and a scrub nurse, and it is clear that the new generation of thoracic surgeons need to use the "less" used hand. The new technology which permitted the introduction of the uniportal VATS could influence the future need of thoracic surgeons worldwide.

    The purpose of the current study is to present the clinical and surgical results in patients who underwent hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection. Thirty-one patients, 27 men and 4 women, underwent segmental-main bronchial sleeve anastomoses for non-small cell lung cancer between May 2004 and May 2011. Twenty-six (83.9%) patients had squamous cell carcinoma, and 5 patients had adenocarcinoma. Six patients were at stage IIB, 24 patients at stage IIIA, and 1 patient at stage IIIB. Secondary sleeve anastomosis was performed in 18 patients, and Y-shaped multiple sleeve anastomosis was performed in 8 patients. Single segmental bronchiole anastomosis was performed in 5 cases. The average time for chest tube removal was 5.6 days. The average length of hospital stay was 11.8 days. No anastomosis fistula developed in any of the patients. The 1-, 2-, and 3-year survival rates were 83.9%, 71.0%, and 41.9%, respectively. Hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection is a complex technique that requires training and experience, but it is an effective and safe operation for selected patients.

    We reported a case of port site metastasis in a 57-year-old patient who underwent video-assisted thoracic surgery (VATS) resection of pulmonary metastasis from breast cancer. Port site metastasis after VATS is very rare in patients with breast cancer. However, when suspicious lesions are detected near the port site in patients who have undergone VATS for pulmonary metastasis, port site metastasis should be considered in the differential diagnosis.

    In this work, a foldable ring-shaped light-emitting diode (LED) lighting assembly, designed to attach to a rubber wound retractor, is realized and tested through porcine animal experiments. Enabled by the small size and the high efficiency of LED chips, the lighting assembly is compact, flexible, and disposable while providing direct and high brightness lighting for more uniform background illumination in video-assisted thoracic surgery (VATS). When compared with a conventional fiber bundle coupled light source that is usually used in laparoscopy and endoscopy, the much broader solid angle of illumination enabled by the LED assembly allows greatly improved background lighting and imaging quality in VATS.

    In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation. Deep neuromuscular blockade should be pursued and carefully monitored, and an appropriate reversal administered before extubation. Management of one-lung ventilation (OLV) needs to be optimized to prevent not only intraoperative hypoxemia but also postoperative acute lung injury (ALI): protective ventilation strategies are therefore to be implemented. Locoregional techniques should be favored over intravenous analgesia: the thoracic epidural, the paravertebral block (PVB), the intercostal nerve block (ICNB), and the serratus anterior plane block (SAPB) are thoroughly reviewed and the most common dosages are reported. Fluid therapy needs to be administered critically, to avoid both overload and cardiovascular compromisation. All these practices are analyzed singularly with the aid of the most recent evidences aimed at the best patient care. Finally, a few notes on some of the latest trends in research are presented, such as non-intubated video-assisted thoracoscopic surgery (VATS) and intravenous lidocaine.

    This is the first case of cardiac re-synchronization therapy (CRT) operated on the ''Hermanos Ameijeiras'' Clinical Surgical Hospital using video-assisted thoracic surgery. Patient is a man aged 67 presenting with a dilated myocardiopathy with severe left ventricular systolic dysfunction. At admission he showed a clinical picture of advanced cardiac insufficiency, thus, we considered the prescription of a CRT. After the failure of the percutaneous therapy for placing a electrode in a epicardiac vein of left ventricle, we decide the minimal invasive surgical approach. The epicardiac electrode implantation by thoracic surgery was a safe procedure without transoperative and postoperative complications. We have knowledge that this is the first time that a video-thoracoscopy in Cardiovascular Surgery is performed in Cuba. (author)

    A clinical pathway provides a scheduled, objective protocol for the multi-disciplinary, evidence-based management of patients with a specific condition or undergoing a specific procedure. In implementing a clinical pathway for the care of patients receiving video-assisted thoracic surgery (VATS) in Hong Kong, many insights were gained into what makes a clinical pathway work: meticulous preparation and team-building are keys to success; the pathway must be constantly reviewed and revisions made in response to evolving clinical need; and data collection is a key element to allow auditing and clinical research. If these can be achieved, a clinical pathway delivers not only measurable improvements in patient outcomes, but also fundamentally complements clinical advances such as VATS. This article narrates the story of how the clinical pathway for VATS in Hong Kong was created and evolved, highlighting how the above lessons were learned.

  18. Video-assisted thoracic surgery for superior posterior mediastinal neurogenic tumour in the supine position

    Full Text Available Video-assisted thoracic surgery (VATS for a superior posterior mediastinal lesion is routinely done in the lateral decubitus position similar to a standard thoracotomy using a double-lumen endotracheal tube for one-lung ventilation. This is an area above the level of the pericardium, with the superior thoracic opening as its superior limit and its inferior limit at the plane from the sternal angle to the level of intervertebral disc of thoracic 4 to 5 vertebra lying behind the great vessels. The lateral decubitus position has disadvantages of the double-lumen endotracheal tube getting malpositioned during repositioning from supine position to the lateral decubitus position, shoulder injuries due to the prolonged abnormal fixed posture and rarer injuries of the lower limb. There is no literature related to VATS in the supine position for treating lesions in the posterior mediastinum because the lung tissue falls in the dependent posterior mediastinum and obscures the field of surgery; however, VATS in the supine position is routinely done for lesions in the anterior mediastinum and single-stage bilateral spontaneous pneumothorax. Thus, in the selected cases, ′VATS in supine position′ allows an invasive procedure to be completed in the most stable anatomical posture.

  19. Transitioning from video-assisted thoracic surgical lobectomy to robotics for lung cancer: are there outcomes advantages?

    2014-02-01

    To determine if there are advantages to transitioning to robotics by a surgeon who is already proficient in performing video-assisted thoracic surgical (VATS) lobectomy. A single surgeon proficient in VATS lobectomy initiated a robotic lobectomy program, and a retrospective review was conducted of his patients undergoing minimally invasive lobectomy (robotics or VATS) for lung cancer between 2011 and 2012. Data collected included patient/tumor characteristics, morbidity, mortality, operative times, and length of hospital stay. Over a 24-month period, a total of 69 patients underwent minimally invasive lobectomy (35 robotic, 34 VATS). Patients in each group were similar in age and clinical stage. Robotic upper lobectomy operative times were longer than VATS (172 vs 134 minutes; P = .001), with no significant difference in lower lobectomies noted (140 vs 123 minutes; P = .1). Median length of stay was 3 days in both groups, and the median number of lymph nodes harvested was 18 (robotic) versus 16 (VATS; P = .42). Morbidity and mortality for robotic versus VATS were 11% versus 18% (P = .46) and 0% versus 3% (P = .49), respectively. There does not seem to be a significant advantage for an established VATS lobectomy surgeon to transition to robotics based on clinical outcomes. The learning curve for robotic upper lobectomies seems to be more significant than that for lower lobectomies. Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc.

    Secondary spontaneous pneumothorax (SSP) is serious entity, usually due to underlying disease, mainly chronic obstructive pulmonary disease (COPD). Its morbidity and mortality is high due to the pulmonary compromised status of these patients, and the recurrence rate is almost 50%, increasing mortality with each episode. For persistent or recurrent SSP, surgery under general anesthesia (GA) and mechanical ventilation (MV) with lung isolation is the gold standard, but ventilator-induced damages and dependency, and postoperative pulmonary complications are frequent. In the last two decades, several groups have reported successful results with non-intubated video-assisted thoracic surgery (NI-VATS) with thoracic epidural anesthesia (TEA) and/or local anesthesia under spontaneous breathing. Main benefits reported are operative time, operation room time and hospital stay reduction, and postoperative respiratory complications decrease when comparing to GA, thus encouraging for further research in these moderate to high risk patients many times rejected for the standard regimen. There are also reports of special situations with satisfactory results, as in contralateral pneumonectomy and lung transplantation. The aim of this review is to collect, analyze and discuss all the available evidence, and seek for future lines of investigation.

    In 2013, the Centers for Medicare and Medicaid Services began its Bundled Payments for Care Improvement Initiative. If payments are to be bundled, surgeons must be able to predict which patients are at risk for more costly care. We aim to identify factors driving variability in hospital costs after video-assisted thoracic surgery (VATS) lobectomy for lung cancer. Our institutional Society of Thoracic Surgeons data were queried for patients undergoing VATS lobectomy for lung cancer during fiscal years 2010 to 2011. Clinical outcomes data were linked with hospital financial data to determine operative and postoperative costs. Linear regression models were created to identify the impact of preoperative risk factors and perioperative outcomes on cost. One hundred forty-nine VATS lobectomies for lung cancer were reviewed. The majority of patients had clinical stage IA lung cancer (67.8%). Median length of stay was 4 days, with 30-day mortality and morbidity rates of 0.7% and 37.6%, respectively. Mean operative and postoperative costs per case were $8,492.31 (±$2,238.76) and $10,145.50 (±$7,004.71), respectively, resulting in an average overall hospital cost of $18,637.81 (±$8,244.12) per patient. Patients with chronic obstructive pulmonary disease and coronary artery disease, as well as postoperative urinary tract infections and blood transfusions, were associated with statistically significant variability in cost. Variability in cost associated with VATS lobectomy is driven by assorted patient and clinical variables. Awareness of such factors can help surgeons implement quality improvement initiatives and focus resource utilization. Understanding risk-adjusted clinical-financial data is critical to designing payment arrangements that include financial and performance accountability, and thus ultimately increasing the value of health care.

Specific training in the uniportal VATS approach is crucial to ensure safety and radical treatment. Such training approach, including a direct interaction with experienced surgeons in high-volume centers, is crucial and represents an indispensable step. Another form of training that usually occurs after preceptorship is proctorship: an experienced mentor can be invited to a trainee’s own center to provide specific on-site tutelage. Videos published online are commonly used as training material. Technology has allowed the use of different models of simulators for training. The most common model is the use of animal wet laboratory training. Other models, however, have been used mostrecently, such as the use of 3D and VR Technology, virtual reality simulators, and completely artificial models of the human thorax with synthetic lung, vessel, airway, and nodal tissues. A short-duration, high-volume, clinical immersion training, and a long term systematic training in high-volume centers are getting more and more attention. According to the evaluation of students' grading, a diversified training mode is adopted and the targeted training in accordance with different students helps to improve the training effect. We have done some work in systematic and standardized training of uniportal VATS in single center. We believe such training is feasible and absolutely necessary.

    OBJECTIVES: No golden standard for analgesia in video-assisted thoracic surgery (VATS) lobectomy exists. A simple multimodal approach using an intercostal catheter (ICC) may be of benefit since acute post-operative pain following VATS lobectomy primarily originates from the chest drain area......) and inserted an ICC at the drain site level for continuous delivery of 6 ml of 0.25% bupivacaine h(-1). Pain scores at rest, mobilization and with the extended arms were followed until discharge or for 4 days. RESULTS: Forty-eight patients, mean age 64 years (CI: 61-68), were included. The mean time...... for the PVB and ICC placement was 5 min (CI: 4.7-5.9). The mean pain score at rest using a numerical rating scale (NRS, 0-10) was 85% of patients reporting satisfactory or very satisfactory pain treatment all days. CONCLUSIONS: Acute pain after VATS lobectomy may be adequately controlled using a multimodal...

    We report a case of lung abscess caused by an ingested fish bone that was successfully treated by minimally invasive surgery. Although cases of ingested foreign body abscess are well reported, lung abscess caused by ingested fish bone is extremely rare. To date, less than 10 similar cases have been reported in the literature. To the best of our knowledge, the case presented in this case report is the first report of this kind that was successfully treated by video-assist thoracic surgery (VATS). A 47-year-old man was admitted to department of thoracic surgery with the complaint of continues dry cough and fever. The patient accidentally swallowed a long sharp-blade-shaped fish bone 20 days before, which perforated the upper thoracic esophagus on the right and embedded in the right upper lobe.The diagnosis was verified by computed tomography scan and a video-assist thoracic surgery procedure was successfully performed to treat the patient. The patient survived the esophageal perforation fortunately without involvement of great vessel injury and probable mediastinitis. This report may provide additional experience on lung abscess caused by ingested fish bones. However, it is also important to educate the public of the risks of trying to force an ingested object down into the stomach.

    The objective of this study was to verify whether the European Society of Thoracic Surgeons prolonged air leak risk score for video-assisted thoracoscopic lobectomy was associated with incremental postoperative costs. We retrospectively analyzed 353 patients subjected to video-assisted thoracoscopic lobectomy or segmentectomy (April 2014 to March 2016). Postoperative costs were obtained from the hospital Finance Department. Patients were grouped in different classes of risk according to their prolonged air leak risk score. To verify the independent association of the prolonged air leak risk score with postoperative costs, we performed a stepwise multivariable regression analysis in which the dependent variable was postoperative cost. Prolonged air leak developed in 56 patients (15.9%). Their length of stay was 3 days longer compared with those without prolonged air leak (8.3 vs 5.4, P validated the European Society of Thoracic Surgeons prolonged air leak risk score for video-assisted thoracoscopic lobectomies, which appears useful in selecting those patients in whom the application of additional intraoperative interventions to avoid prolonged air leak may be more cost-effective.

    The thoracic morbidity and mortality (TM&M) classification system univocally encodes the postoperative adverse events by their management complexity. This study aims to compare the distribution of the severity of complications according to the TM&M system versus the distribution according to the classification proposed by European Society of Thoracic Surgeons (ESTS) Database in a population of patients submitted to video assisted thoracoscopic surgery (VATS) lung resection. A total of 227 consecutive patients submitted to VATS lobectomy for lung cancer were analyzed. Any complication developed postoperatively was graded from I to V according to the TM&M system, reflecting the increasing severity of its management. We verified the distribution of the different grades of complications and analyzed their frequency among those defined as "major cardiopulmonary complications" by the ESTS Database. Following the ESTS definitions, 20 were the major cardiopulmonary complications [atrial fibrillation (AF): 10, 50%; adult respiratory distress syndrome (ARDS): 1, 5%; pulmonary embolism: 2, 10%; mechanical ventilation >24 h: 1, 5%; pneumonia: 3, 15%; myocardial infarct: 1, 5%; atelectasis requiring bronchoscopy: 2, 10%] of which 9 (45%) were reclassified as minor complications (grade II) by the TM&M classification system. According to the TM&M system, 10/34 (29.4%) of all complications were considered minor (grade I or II) while 21/34 (71.4%) as major (IIIa: 8, 23.5%; IIIb: 4, 11.7%; IVa: 8, 23.5%; IVb: 1, 2.9%; V: 3, 8.8%). Other 14 surgical complications occurred and were classified as major complications according to the TM&M system. The distribution of postoperative complications differs between the two classification systems. The TM&M grading system questions the traditional classification of major complications following VATS lung resection and may be used as an additional endpoint for outcome analyses.

Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative. Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (Pport thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

    The aim of this study was to assess the feasibility, efficacy and safety of a modified silicone fluted drain tube after video-assisted thoracic surgery (VATS) lung resection. The prospective randomized study included 50 patients who underwent VATS lung resection between March 2015 and June 2015. Eligible patients were randomized into two groups: experimental group (using the silicone fluted drain tubes for chest drainage) and control group (using standard drain tubes for chest drainage). The volume and characteristics of drainage, postoperative (PO) pain scores and hospital stay were recorded. All patients received standard care during hospital admission. In accordance with the exit criteria, three patients were excluded from study. The remaining 47 patients included in the final analysis were divided into two groups: experiment group (N=24) and control group (N=23). There was no significant difference between the two groups in terms of age, sex, height, weight, clinical diagnosis and type of surgical procedure. There was a trend toward less PO pain in experimental group on postoperative day (POD) 1, with a statistically significant difference. Patients in experimental group had a reduced occurrence of fever [temperature (T) >37.4 °C] compared to the control group. The silicone fluted drain tube is feasible and safe and may relieve patient PO pain and reduce occurrence of fever without the added risk of PO complications.

    Single-port access video-assisted thoracic surgery (VATS), a technique progressively developed from the standard three-port approach in minimally invasive surgery, offers ergonomic advantages but also new challenges for the surgeon. We compared the ergonomics of three-port versus single-port VATS. Posture analysis of surgeons was evaluated during 100 consecutive VATS wedge resections (50 triportal vs. 50 uniportal). Technically demanding procedures (major lung resection) were excluded. Operating table height, monitor height, distance and inclination were adjusted according to operator preference. Body posture was assessed by measuring head-trunk axial rotation and head flexion. Perceived physical strain was self-evaluated on the Borg Category Ratio (CR-10) scale. Mental workload was assessed with the National Aeronautics Space Administration-Task Load indeX (NASA-TLX), a multidimensional tool that rates workloads on six scales (mental, physical and temporal demand; effort; performance; frustration). All procedures were completed without complications. Head-trunk axial rotation was significantly reduced and neck flexion significantly improved in uniportal VATS. Viewing direction significantly declined (p = 0.01), body posture as measured on the Borg CR-10 scale was perceived as more stressful and the NASA-TLX score for overall workload was higher (p = 0.04) during triportal VATS. The NASA-TLX score for frustration was higher with uniportal VATS (p = 0.02), but the score for physical demand was higher in triportal VATS (p = 0.006). The surgeon can maintain a more neutral body posture during uniportal VATS by standing straight and facing the monitor with only minimal neck extension/rotation; however, frustration is greater than with triportal VATS.

    Thoracoscopic surgery has been applied in medicine for more than 100 years. Still it is only within the last decade that it has gained momentum as a method in non-small cell lung cancer (NSCLC) surgery. Several approaches have been published, one of the more resent being uniportal video-assisted thoracic surgery (VATS). In this article we describe the transition from thoracotomy to uniportal VATS in our institution, the last step to uniportal VATS exemplified with two cases performed during our masterclass held in May 2016.

    Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

    Compared to the pulmonary lobe, the anatomical structure of the pulmonary segment is relatively complex and prone to variation, thus the risk and difficulty of segmentectomy is increased. We compared three-dimensional computed tomography bronchography and angiography (3D-CTBA) combined with 3D video-assisted thoracic surgery (3D-VATS) to perform segmentectomy to conventional two-dimensional (2D)-VATS for the treatment of non-small cell lung cancer (NSCLC). We retrospectively reviewed the data of randomly selected patients who underwent 3D-CTBA combined with 3D-VATS (3D-CTBA-VATS) or 2D-VATS at the Department of Thoracic Surgery, The First Affiliated Hospital of Soochow University Hospital, from January 2014 to May 2017. The operative duration of 3D group was significantly shorter than the 2D group (P 0.05). The extent of intraoperative bleeding and postoperative drainage in the 3D group was significantly lower than in the 2D group (P 3D group was shorter than in the 2D group (P 0.05). However, hemoptysis and pulmonary air leakage (>3d) occurred significantly less frequently in the 3D than in the 2D group (P 3D-CTBA-VATS is a more accurate and smooth technique and leads to reduced intraoperative and postoperative complications. © 2018 The Authors.

Optimization of perio-perative analgesia method, then reduce perioperative stress response, reduce opioiddosage, to reduce or even avoid systemic adverse reactions and elevated levels of tumor markers. Serum levels of tumor markers in patients with lung cancer are closely related to tumor growth. Clinical research reports on regional anesthesia effect on tumor markers for lung cancer are still very little in domesticliterature. The aim of this study is to evaluate the effects of thoracic paraverte-bral block on postoperative analgesia and serum level of tumor marker in lung cancer patients undergoing video-assisted thoracoscopic surgery. Methods Lung cancer patients undergoing video-assisted thoracoscopic surgery were randomly divided into 2 groups (n=20 in each group. The patients in group G were given only general anesthesia. The thoracic paravertebral blockade (PVB was performed before general anesthesia in patients of group GP. The effect of PVB was judged by testing area of block.

    Full Text Available Background and objective Thoracoscopic surgery has gradually become the major procedure for lung cancer surgery in our department. Its characteristics are minimal trauma and quick recovery, which make approximately 90% of patients discharge from the hospital after surgery. However, the postoperative complications still happen now and then. We analyzed the patients who had been hospitalized for longer than 7 days after thoracoscopic lung cancer surgery, aiming to summarize the types and risk factors of complications, and improve postoperative safety of patients. Methods The data were come from the prospective database of Thoracic Surgery Unit One in Peking Cancer Hospital, and patients that underwent thoracoscopic pulmonary surgery between Jan. 2010 and Dec. 2014 with length of stay more than 7 days were included in the study. The classifications of the complications were investigated and graded as mild or severe complications according to modified Claviengrading, the relationship between clinical factors and degrees of complications was also analyzed. Results The hospitalization of 115 cases were longer than 7 days after surgery, accounting for 10.3% (115/1,112 of the whole patients that underwent surgery during the same period. Eighty-one cases had mild complications, accounting for 7.3% (81/1,112 of the whole cases that underwent surgery during the same period and 70.4% (81/115 of the cases with prolonged length of stay; the proportions of severe complications in both groups were 3.1% (34/1,112 and 29.6% (34/115, respectively; and the proportions of complications that caused perioperative deaths were 0.18% (2/1112 and 1.7% (2/115, respectively. Among all the postoperative complications, the most common was air leakage for more than 5 days after surgery, with a total of 20 cases (1.8% and 17.4%. The other common complications were: atelectasis (19 cases, 1.7% and 16.5%, pulmonary infection (18 cases, 1.6% and 15.7%, etc. The less common

    Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC). We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (Popen groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches. Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

    We report surgical management of radiation-induced massive pericardial effusion. A 55-year-old man undergoing definitive chemoradiotherapy (CRT) for esophageal squamous cell carcinoma in the middle thorax was treated with megavoltage equipment using anterior-posterior opposed fields up to 45 Gy, including the primary tumor and regional lymphnodes. A booster dose of 25 Gy was given to the primary tumor for a total dose of 70 Gy, using bilateral oblique fields. Three years and 6 months later, he was treated with an additional 30 Gy for mediastinal lymphnode metastasis, followed by percutaneous pericardiocentesis for cardiac tamponade with massive pericardial effusion 4 times in 5 months. Because medical intervention was inadequate, he underwent pericardial effusion via video-assisted thoracoscopic pericardial window placement 4 years and 6 months after definitive CRT. Histopathological examination of the pericardial tissue specimen showed marked fibrosis but no cancer recurrence, compatible with radiation pericarditis. The postoperative course was uneventful, and pericardial effusion completely disappeared. (author)

    The optimal regional technique for analgesia and improved quality of recovery after video-assisted thoracic surgery (a procedure associated with considerable postoperative pain) has not been established. The main objective in this study was to compare quality of recovery in patients undergoing serratus plane block (SPB) with either ropivacaine or normal saline on the first postoperative day. Secondary outcomes were analgesic outcomes, including postoperative pain intensity and opioid consumption. Ninety patients undergoing video-assisted thoracic surgery were randomized to receive ultrasound-guided SPB with 0.4 mL/kg of either 0.375% ropivacaine (SPB group) or normal saline (control group) after anesthetic induction. The primary outcome was the 40-item Quality of Recovery (QoR-40) score at 24 hours after surgery. The QoR-40 questionnaire was completed by patients the day before surgery and on postoperative days 1 and 2. Pain scores, opioid consumption, and adverse events were assessed for 2 days postoperatively. Eighty-five patients completed the study: 42 in the SPB group and 43 in the control group. The global QoR-40 scores on both postoperative days 1 and 2 were significantly higher in the SPB group than in the control group (estimated mean difference 8.5, 97.5% confidence interval [CI], 2.1-15.0, and P = .003; 8.5, 97.5% CI, 2.0-15.1, and P = .004, respectively). The overall mean difference between the SPB and control groups was 8.5 (95% CI, 3.3-13.8; P = .002). Pain scores at rest and opioid consumption were significantly lower up to 6 hours after surgery in the SPB group than in the control group. Cumulative opioid consumption was significantly lower up to 24 hours postoperatively in the SPB group. Single-injection SPB with ropivacaine enhanced the quality of recovery for 2 days postoperatively and improved postoperative analgesia during the early postoperative period in patients undergoing video-assisted thoracic surgery.

Prospective observational study. Medical center. ASA physical status 1-2 patients undergoing elective lung surgeries including pneumonectomy, lobectomy, and segmentectomy performed through either the anterolateral approach or video-assisted thoracotomy surgery. Postoperative observation of ipsilateral shoulder pain. Postoperative examinations of sites of shoulder pain (clavicle, anterior, lateral,or posterior aspect of acromion, posterior neck, supraspinatus, infraspinatus, and these entire areas) with or without trigger points, visual analog scale score of wound pain, and requested counts of analgesics. The number of patients who suffered from postoperative shoulder pain was 37 of 70 (52.9%). Demographic data, anterolateral/VATS ratio, VAS scores, and requested counts of rescue analgesics requirement were similar in the groups of patients with and without postoperative shoulder pain. The segmentectomy caused a significantly higher incidence of postoperative shoulder pain compared with other procedures (p shoulder pain showed defined trigger points in their painful areas. These results supported the hypothesis that myofascial involvement contributed, to some extent, to shoulder pain after muscle-sparing thoracotomy with ipsilateral upper extremity elevation.

    The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases. RESUMO O conceito de sala híbrida traduz a união de um aparato cirúrgico de alta complexidade com recursos radiológicos de última geração (ultrassom, TC, radioscopia e/ou ressonância magnética), visando a realização de procedimentos minimamente invasivos e altamente eficazes. Apesar de bem estabelecido em outras especialidades, como neurocirurgia e cirurgia cardiovascular, o uso da sala hibrida ainda é pouco explorado na cirurgia torácica. Nosso objetivo foi discutir as aplicações e as possibilidades abertas por essa tecnologia na cirurgia torácica através do relato de três casos.

    Thoracic trauma is a challenging situation with potential severe chest wall and intrathoracic organ injuries. We present a case of emergent surgery in a 23-year-old man with hemorrhagic shock due to massive lung and chest wall injury after thoracic trauma in a water slide. We performed a SI-VATS approach in order to define intrathoracic and chest wall injuries, and once checked the extension of the chest wall injury, we added a middle size thoracotomy just over the affected area in order to stabilize rib fractures with Judet plates, that had caused massive laceration in left lower lobe (LLL) and injured the pericardium causing myocardical tear. After checking bronchial and vascular viability of LLL we suggested a lung parenchyma preserving technique with PTFE protected pulmonary primary suture in order to avoid a lobectomy. Chest tubes were removed on 3 rd postoperative day and patient was discharged on 14 th postoperative day. He has already recovered his normal activity 6 months after surgery.

    Full Text Available Abstract A right aortic arch is a rare congenital anomaly, with a reported incidence of around 0.1%. A patient with a right aortic arch underwent video-assisted thoracic surgery left lower lobectomy and mediastinal lymph node dissection for squamous cell carcinoma. There was no aortic arch or descending aorta in the left thoracic cavity, but the esophagus. There was no anomaly in the location or branching of the pulmonary vessels, the bronchi, and the lobulation of the lungs. The vagus nerve was found at the level of the left pulmonary artery. The arterial ligament was found between the left subclavian artery and the left pulmonary artery. The recurrent laryngeal nerve was recurrent around the left subclavian artery. A Kommerell diverticulum was found at the origin of the left subclavian artery. The patient experienced no complications. We conclude that video-assisted thoracoscopic lobectomy with mediastinal dissection is feasible for treating lung cancer with a right aortic arch.

    The incidence rate of prolonged air leak (PAL) after lobectomy, defined as any air leak prolonged beyond 7 days, can be estimated to be in between 6 and 15%. In 2011, the Epithor group elaborated an accurate predictive score for PAL after open lung resections, so-called IPAL (index of prolonged air leak), from a nation-based surgical cohort constituted between 2004 and 2008. Since 2008, video-assisted thoracic surgery (VATS) has become popular in France among the thoracic surgical community, reaching almost 14% of lobectomies performed with this method in 2012. This minimally invasive approach was reported as a means to reduce the duration of chest tube drainage. The aim of our study was thus to validate the IPAL scoring system in patients having received VATS anatomical lung resections. We collected all anatomical VATS lung resections (lobectomy and segmentectomy) registered in the French national general thoracic surgery database (EPITHOR) between 2009 and 2012. The area under the receiver operating characteristic (ROC) curve estimated the discriminating value of the IPAL score. The slope value described the relation between the predicted and observed incidences of PALs. The Hosmer-Lemeshow test was also used to estimate the quality of adequacy between predicted and observed values. A total of 1233 patients were included: 1037 (84%) lobectomies and 196 (16%) segmentectomies. In 1099 cases (89.1%), the resection was performed for a malignant disease. Ninety-six patients (7.7%) presented with a PAL. The IPAL score provided a satisfactory predictive value with an area under the ROC curve of 0.72 (0.67-0.77). The value of the slope, 1.25 (0.9-1.58), and the Hosmer-Lemeshow test (χ(2) = 11, P = 0.35) showed that predicted and observed values were adequate. The IPAL score is valid for the estimation of the predictive risk of PAL after VATS lung resections. It may thus a priori be used to characterize any surgical population submitted to potential preventive measures

    The objective of the present study was to compare functional loss [forced expiratory volume in one second to forced vital capacity ratio (FEV1), DLCO and VO2max reduction] after VATS versus open lobectomies. We performed a prospective observational study on 195 patients who had a pulmonary lobectomy from June 2010 to November 2014 and who were able to complete a 3-months functional evaluation follow-up program. Since the VATS technique was our first choice for performing lobectomies from January 2012, we divided the patients into two groups: the OPEN group (112 patients) and the VATS group (83 patients). The open approach was intended as a muscle sparing/nerve sparing lateral thoracotomy. Fourteen baseline factors were used to construct a propensity score to match the VATS-group patients with their OPEN-group counterparts. These two matched groups were then compared in terms of reduction of FEV1, DLCO and VO2max (Mann-Whitney test). The propensity score analysis yielded 83 well-matched pairs of OPEN and VATS patients. In both groups, 3 months postoperatively, we found a reduction in FEV1, DLCO and VO2max values (OPEN patients: FEV1-10%, DLCO -11.9%, VO2max - 5.5%; VATS patients: FEV1-7.2%, DLCO-10.6%, VO2max-6.9%). The reductions in FEV1, DLCO and VO2max were similar to those in the two matched groups, with a Cohen effect size offer any advantages in terms of FEV1, DLCO and exercise capacity recovery in comparison to the muscle-sparing thoracotomy approach. © The Author 2017.

    Competence in video-assisted thoracoscopic surgery lobectomy has previously been established on the basis of numbers of procedures performed, but this approach does not ensure competence. Specific assessment tools, such as the newly developed video-assisted thoracoscopic surgery lobectomy assessment tool, allow for structured and objective assessment of competence. Our aim was to provide validity evidence for the video-assisted thoracoscopic surgery lobectomy assessment tool. Video recordings of 60 video-assisted thoracoscopic surgery lobectomies performed by 18 thoracic surgeons were rated using the video-assisted thoracoscopic surgery lobectomy assessment tool. All 4 centers of thoracic surgery in Denmark participated in the study. Two video-assisted thoracoscopic surgery experts rated the videos. They were blinded to surgeon and center. The total internal consistency reliability Cronbach's alpha was 0.93. Inter-rater reliability between the 2 raters was Pearson's r = 0.71 (P video-assisted thoracoscopic surgery lobectomy assessment tool scores for the 10 procedures performed by beginners were 22.1 (standard deviation [SD], 8.6) for the 28 procedures performed by the intermediate surgeons, 31.2 (SD, 4.4), and for the 20 procedures performed by experts 35.9 (SD, 2.9) (P better than intermediates (P better than beginners (P video-assisted thoracoscopic surgery lobectomy (video-assisted thoracoscopic surgery lobectomy assessment tool) in a clinical setting.

    The branching patterns of pulmonary arteries and veins vary greatly in the pulmonary hilar region and are very complicated. We attempted to reconstruct anatomically correct images using a freeware program. After uploading the images to a personal computer, bronchi, pulmonary arteries and veins were traced by moving up and down in the images and the location and thickness of the bronchi and pulmonary vasculture were indicated as different-sized cylinders. Next, based on the resulting numerical data, a 3D image was reconstructed using Metasequoia shareware. The reconstructed images can be manipulated by virtual surgical procedures such as reshaping, cutting and moving. These system would be very helpful in complicated video-assisted thoracic surgery such as lung segmentectomy.

    The purpose of this study was to explore the indications of radical vedio-assisted mediastinoscopic resection for esophageal cancer. The data of 109 patients with T1 esophageal cancer who underwent video-assisted mediastinoscopic resection (VAMS group) in Third Affiliated Hospital of Soochow University Hospital from December 2005 to December 2011 were collected in the study for comparison with the 58 patients with T1 esophageal cancer who underwent video-assisted thoracoscopic surgery (VATS group) in Zhongshan Hospital, Fudan University. The perioperative safety and survival were compared between the two groups. All operations were successful in both groups. One perioperative death was noted in the VATS group. The incidences of post-operative complications were not significantly different between these two groups, whereas the VAMS group was favorable in terms of operative time (P<0.001) and blood loss (P<0.001), and a significantly larger number of chest lymph nodes were dissected in the VATS group compared with the VAMS group (P<0.001). Long-term follow-up showed that the overall survival was not significantly different between these two groups (P=0.876). T1N0M0 esophageal cancer can be as the indication of VAMS radical resection. VAMS radical resection can be considered as the preferred option for patients with poor pulmonary and cardiac function or a history of pleural disease.

    Full Text Available Background: Postoperative morbidity and inhospital length of stay are considered major determinants of total health care expenditure associated with thoracic operations. The aim of this study was to prospectively evaluate the role of video-assisted thoracic surgery (VATS compared to mini-muscle-sparing thoracotomy in facilitating early recovery and hospital discharge after pulmonary sublobar wedge resections. Patients and Methods: A total number of 120 patients undergoing elective pulmonary sublobar wedge resection were randomly assigned to VATS (n = 60 or mini-muscle-sparing thoracotomy (n = 60. The primary endpoint was time to hospital discharge. Postoperative complications, cardiopulmonary morbidity and 30-day mortality served as secondary endpoints. Results: Patients' baseline demographic and clinical data did not differ among study arms as well as the number of pulmonary segments resected and the morphology of the nodular lesions. Total hospital stay was significantly shorter in patients assigned to the thoracoscopic technique as opposed to those who were operated using the mini-muscle-sparing thoracotomy approach (4 ± 0.6 versus 4.4 ± 0.6 days respectively, P = 0.006. Multivariate analysis revealed that VATS approach was inversely associated with longer inhospital stay whereas the number of resected segments was positively associated with an increased duration of hospitalization. Patients in the VATS group were less likely to develop atelectasis (≥1 lobe compared to those who underwent thoracotomy (0% versus 6.7% respectively, P = 0.042. Kaplan-Meier analysis revealed similar 30-day mortality rates in both study arms (Log-rank P = 0.560. Conclusion: VATS was associated with shorter duration of hospitalization positively affecting the patients' quality of life and satisfaction. Significant suppression of the total cost of recovery after thoracoscopic pulmonary resections is expected.

    Full Text Available Severe intrathoracic hemorrhage from pulmonary parenchyma is the most serious complication of pulmonary laceration after blunt trauma requiring immediate surgical hemostasis through open thoracotomy. The safety and efficacy of video-assisted thoracoscopic surgery (VATS techniques for this life-threatening condition have not been fully evaluated yet. We report a case of pulmonary laceration with a massive hemothorax after blunt trauma successfully treated using a combination of muscle-sparing minithoracotomy with VATS techniques (video-assisted minithoracotomy. A 22-year-old man was transferred to our department after a falling accident. A diagnosis of right-sided pneumothorax was made on physical examination and urgent chest decompression was performed with a tube thoracostomy. Chest computed tomographic scan revealed pulmonary laceration with hematoma in the right lung. The pulmonary hematoma extending along segmental pulmonary artery in the helium of the middle lobe ruptured suddenly into the thoracic cavity, resulting in hemorrhagic shock on the fourth day after admission. Emergency right middle lobectomy was performed through video-assisted minithoracotomy. We used two cotton dissectors as a chopstick for achieving compression hemostasis during surgery. The patient recovered satisfactorily. Video-assisted minithoracotomy can be an alternative approach for the treatment of pulmonary lacerations with a massive hemothorax in hemodynamically unstable patients.

    Minimally invasive and video assisted mitral valve surgery has been used widely since beginning of 20 th . Different reduced surgical approaches allowed replacing or repairing a mitral valve sparing sternal incision. Nevertheless the most used strategy has been in the last years the right mini thoracotomy and the extra thoracic cardiopulmonary bypass (CPB). The main goal is avoiding sternal approach for mitral valve procedures and improve postoperative course of the patients. Some postoperative complication likes blood loss, need for transfusion, prolonged intubation and infection has been reduced using this alternative technique. A special advantages has been reported in elderly or high risk patients and in redo cases. Several cardiac centres using videoscopy and a revolutionary set up for CPB management and aortic occlusion have adopted the approach. The team approach, including surgeon, anaesthesiologist, nurse, cardiologist and perfusionist, is crucial for a safe and effective realization of this surgical strategy. The proper use of catheters and Seldinger skilfulness, and the guidance of trans-esophageal echocardiography (TEE) during the procedure are two milestones of this technique. A careful and progressive learning curve is required for all the components of the team. In fact some peculiarity likes modified surgical instruments, 3D and Full HD video assisted view, percutaneous canulation for CPB and myocardial protection, etc., make this procedure challenging for all members of the operative room (OR) team. Our favourite set-up include right mini thoracotomy in the IV intercostal space, femoral vein and arterial canulation and an additional venous cannula in the superior vena cava for the drainage of the upper part of the body. Aortic occlusion is achieved usually using an endo-aortic clamp positioned by means of continuous and careful TEE guidance. A mitral valve procedure is realized by direct or video guided view; using adapted and shaft instruments or

    Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis. PMID:24782978

    Full Text Available ABSTRACT Objective: The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Methods: Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. Results: The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6. However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5% were male. The majority-521 (89.8%-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2% were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%. Postoperative complications occurred in 124 patients (19.1%, the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Conclusions: Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.

    To study the feasible and safe volume threshold for chest tube removal following video-assisted thoracoscopic surgical lobectomy. One hundred and sixty-eight consecutive patients (18 were excluded) who underwent video-assisted thoracoscopic surgery lobectomy or bilobectomy with two incisions between August 2012 and February 2014 were included. Eligible patients were randomized into three groups: Group A (chest tube was removed at a drainage volume of 150 ml/day or less. n = 49); Group B (chest tube was removed when the drainage volume was less than 300 ml/day. n = 50); Group C (chest tube was removed when the drainage volume was less than 450 ml/day. n = 51). The postoperative care of all patients was consistent. The time of extracting the drainage tube, postoperative hospital stay, postoperative visual analogue scale grades, dosage of analgesic, and the incidence of complications and thoracocentesis were measured. Group B and C had a much shorter drainage time and postoperative hospital stay than Group A (P 0.05). The mean dosage of pethidine hydrochloride was 248.9 ± 33.3 mg in Group B and 226.1 ± 32.7 mg in Group C (P > 0.05). The dosage of pethidine hydrochloride of Group A was significantly higher than that of Group B and C (P 0.05), Group A had a significantly higher total VAS score than Group B and C (P drains among the three groups (P > 0.05). A 300-ml/day volume threshold for chest tube removal after video-assisted thoracoscopic surgery lobectomy is feasible and safe, demonstating more advantages than the 150-ml/day volume threshold. However, a 450-ml/day volume threshold for chest tube removal may increase the risk of thoracentesis compared with the 300- and the 150-ml/day volume threshold. © The Author 2015.

    This study was designed to compare the long-term clinical outcomes and costs between video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PT) in neonates and infants. This study enrolled 302 patients with isolated patent ductus arteriosus (PDA) from January 2002 to 2007 and followed them up until April 2010. A total of 134 patients underwent total VATS (VATS group), and 168 underwent PDA closure through PT (PT group). The two groups were compared according to clinical outcomes and costs. The demographics and preoperative clinical characteristics of the patients were similar in the two groups. No cardiac deaths occurred, and the closure rate was 100% successful in both groups. The operating, recovery, and pleural fluid drainage times were significantly shorter in the VATS group than in the PT group. Statistically significant differences in length of incision, postoperative temperature, and acute procedure-related complications were observed between the two groups. The cost was $1,150.3 ± $221.2 for the VATS group and $2415.8 ± $345.2 for the PT group (P ventricular end-diastolic diameter and the pulmonary artery diameter could be restored to normal in the VATS group but not in the PT group. The study confirmed that VATS offers a minimally traumatic, safe, and effective technique for PDA interruption in neonates and infants.

    Video-assisted thoracoscopic surgery is a widespread technique that has been linked to improved postoperative respiratory function, reduced hospital length of stay and a higher level of tolerability for the patients. Acute postoperative pain is of considerable significance, and the late development of neuropathic pain syndrome is also an issue. As anaesthesiologists, we have investigated the available evidence to optimize postoperative pain management. An opioid-sparing multimodal approach is highly recommended. Loco-regional techniques such as the thoracic epidural and peripheral blocks can be performed. Several adjuvants have been employed with varying degrees of success both intravenously and in combination with local anesthetics. Opioids with different pharmacodynamic and pharmacokinetic profiles can be used, either through continuous infusion or on demand. Non-opioid analgesics are also beneficial. Finally, perioperative gabapentinoids may be implemented to prevent the onset of chronic neuropathic pain.

    To evaluate the efficacy and safety of lung biopsies by video-assisted thoracoscopy surgery (VATS) in the diagnosis of undefined interstitial lung disease (ILD). The retrospective analysis was performed in 32 who patients underwent VATS for the diagnosed with ILD from Jan 2007 to Dec 2011. The main reason for VATS for all the patients was due to no specific diagnosis could be obtained after non-invasive methods, transbronchial lung biopsy (TBLB) examination and the consultation with pulmonologist, radiologist and pathologist. The clinical profiles, chest high resolution computerized tomography (HRCT), laboratory profile, TBLB as well as the diagnosis of before and after the VATS were analyzed. The surgery site, biopsy number, duration of the thoracic drain, post-operative complications were also recorded. The 30- and 90-day post-operative mortality rates were calculated. The risk factors associated with the incidence of post-operative complications were assessed. The specific diagnosis could be established in all patients after VATS lung biopsies, with change from previous ones in 27 (84.4%). Among 20 cases (62.5%) diagnosed as unclassified ILD before the surgery, 14 (70.0%) were diagnosed as nonspecific interstitial pneumonia (NSIP), 3 (15.0%) as idiopathic pulmonary fibrosis (IPF) and 3 (15.0%) as connective tissue disease-related ILD (CTD-ILD). Among the 7 cases with complete change of diagnosis after VATS, 4 (57.1%) were cryptogenic organizing pneumonia (COP). The number of site of biopsy had no significant impact on the diagnostic efficacy. There were no significant change of vital sign and lung function after the VATS. 21 (65.6%) patients had post-operative complications, including pulmonary infection (56.3%), pulmonary atelectasis (28.1%) and pneumothorax (25.0%). The 30- and 90-day mortality rates were 0 and 5.2% respectively. Patients were divided into 2 groups based on the incidence of post-operative complications, and no significant difference was found

    Air embolism is a relatively rare complication of thoracoscopic surgery. Open supraclavicular sympathectomy was indicated to overcome the risk of re-embolization. A novel video-assisted technique was performed. conclusions: The previously prevalent open supraclavicular sympathectomy is a good choice for avoiding air embolism. Laparoscopic instrumentation and technology can be used to improve open procedures, especially when exposure and visibility are limited. Sometimes we should remember to use the experience of our teachers.

    Over the past two decades, video-assisted thoracoscopic blebectomy and pleurodesis have been used as a safe and reliable option for treatment of spontaneous pneumothorax. The aim of this study is to evaluate the long-term outcome of video-assisted thoracoscopic surgery (VATS) treatment of spontaneous pneumothorax in young patients, and to identify risk factors for postoperative recurrence. We retrospectively analysed the outcome of VATS treatment of spontaneous pneumothorax in our institution in 150 consecutive young patients (age ≤ 40 years) in the years 1997-2010. Treatment consisted of stapling blebectomy and partial parietal pleurectomy. After excluding 16 patients lost to follow-up, in 134 cases [110 men, 24 women; mean age, 25 ± 7 standard deviation years; median follow-up, 79 months (range: 36-187 months)], we evaluated postoperative complications, focusing on pneumothorax recurrence, thoracic dysaesthesia and chronic chest pain. Risk factors for postoperative pneumothorax recurrence were analysed by logistic regression. Of 134 treated patients, 3 (2.2%) required early reoperation (2 for bleeding; 1 for persistent air leaks). Postoperative (90-day) mortality was nil. Ipsilateral pneumothorax recurred in 8 cases (6.0%) [median time of recurrence, 43 months (range: 1-71 months)]. At univariate analysis, the recurrence rate was significantly higher in women (4/24) than in men (4/110; P = 0.026) and in patients with >7-day postoperative air leaks (P = 0.021). Multivariate analysis confirmed that pneumothorax recurrence correlated independently with prolonged air leaks (P = 0.037) and with female gender (P = 0.045). Chronic chest wall dysaesthesia was reported by 13 patients (9.7%). In 3 patients, (2.2%) chronic thoracic pain (analogical score >4) was recorded, but only 1 patient required analgesics more than once a month. VATS blebectomy and parietal pleurectomy is a safe procedure for treatment of spontaneous pneumothorax in young patients, with a 6% long

    Major lung resection using minimally invasive techniques - video-assisted thoracoscopic surgery (VATS) - was first described 20 years ago. However, its development has been slow in many countries because the value of this approach has been questioned. Different techniques and definitions of VATS are used and this can be confusing for physicians and surgeons. The benefit of minimally invasive thoracic surgery was not always apparent, while many surgeons pointed to suboptimal operative outcomes. Recently, technological advances (radiology, full HD monitor and new stapler devices) have improved VATS outcomes. The objectives of this review are to emphasize the accepted definition of VATS resection, outline the different techniques developed and their results including morbidity and mortality compared to conventional approaches. Minimally invasive thoracic surgery has not been proven to give superior survival (level one evidence) compared to thoracotomy. A slight advantage has been demonstrated for short-term outcomes. VATS is not a surgical revolution but rather an evolution of surgery. It should be considered together with the new medical environment including stereotactic radiotherapy and radiofrequency. VATS seems to be more accurate in the treatment of small lung lesions diagnosed with screening CT scan. In the academic field, VATS allows easier teaching and diffusion of techniques.

    To determine whether surgeon selection of instrumentation and other supplies during video-assisted thoracoscopic lobectomy (VATSL) can safely reduce intraoperative costs. In this retrospective, cost-focused review of all video-assisted thoracoscopic surgery anatomic lung resections performed by 2 surgeons at a single institution between 2010 and 2014, we compared VATSL hospital costs and perioperative outcomes between the surgeons, as well as costs of VATSL compared with thoracotomy lobectomy (THORL). A total of 100 VATSLs were performed by surgeon A, and 70 were performed by surgeon B. The preoperative risk factors did not differ significantly between the 2 groups of surgeries. Mean VATSL total hospital costs per case were 24% percent greater for surgeon A compared with surgeon B (P = .0026). Intraoperative supply costs accounted for most of this cost difference and were 85% greater for surgeon A compared with surgeon B (P costs, accounting for 55% of the difference in intraoperative supply costs between the surgeons. Operative time was 25% longer for surgeon A compared with surgeon B (P accounted for only 11% of the difference in total cost. Surgeon A's overall VATSL costs per case were similar to those of THORLs (n = 100) performed over the same time period, whereas surgeon B's VATSL costs per case were 24% less than those of THORLs. On adjusted analysis, there was no difference in VATSL perioperative outcomes between the 2 surgeons. The costs of VATSL differ substantially among surgeons and are heavily influenced by the use of disposable equipment/devices. Surgeons can substantially reduce the costs of VATSL to far lower than those of THORL without compromising surgical outcomes through prudent use of costly instruments and technologies.

    Retained haemothorax and pneumothorax are the most common complications after blunt chest traumas. Lung lacerations derived from fractures of the ribs are usually found in these patients. Video-assisted thoracoscopic surgery (VATS) is usually used as a routine procedure in the treatment of retained pleural collections. The objective of this study was to find out if there is any advantage in adding the procedure for repairing lacerated lungs during VATS. Patients who were brought to our hospital with blunt chest trauma were enrolled into this prospective cohort study from January 2004 to December 2011. All enrolled patients had rib fractures with type III lung lacerations diagnosed by CT scans. They sustained retained pleural collections and surgical drainage was indicated. On one group, only evacuation procedure by VATS was performed. On the other group, not only evacuations but also repair of lung injuries were performed. Patients with penetrating injury or blunt injury with massive bleeding, that required emergency thoracotomy, were excluded from the study, in addition to those with cardiovascular or oesophageal injuries. During the study period, 88 patients who underwent thoracoscopy were enrolled. Among them, 43 patients undergoing the simple thoracoscopic evacuation method were stratified into Group 1. The remaining 45 patients who underwent thoracoscopic evacuation combined with resection of lung lacerations were stratified into Group 2. The rates of post-traumatic infection were higher in Group 1. The durations of chest-tube drainage and ventilator usage were shorter in Group 2, as were the lengths of patient intensive care unit stay and hospital stay. When compared with simple thoracoscopic evacuation methods, repair and resection of the injured lungs combined may result in better clinical outcomes in patients who sustained blunt chest injuries. © The Author 2013.

    The emergence of ultra-high-volume centres promises new opportunities for thoracic surgical training. The goal of this study was to investigate the effectiveness of a novel observership course in teaching video-assisted thoracoscopic surgery (VATS) at an ultra-high-volume centre. Two-week courses in VATS at a specialist unit now performing >10 000 major lung resections annually (>50 daily on average) were attended by 230 surgeons from around the world from 2013 to 2016. An online survey preserving responder anonymity was completed by 156 attendees (67.8%). Attendees included 37% from Western Europe, 18% from Eastern Europe and 17% from Latin America. Experience with open thoracic surgery for more than 5 years was reported by 67%, but 79% had less than 5 years of VATS lobectomy experience. During the course, 70% observed over 30 uniportal VATS operations (including 38% observing over 50), and 69% attended an animal wet lab. Although 72% of the responders attended the course less than 12 months ago, the number of ports used (P < 0.001), operation times (P < 0.001) and conversion rates (P < 0.001) reported by the responders were reduced significantly after the course. Improvements in the problem areas of tissue retraction, instrumentation, stapler application and coordination with the assistant during VATS were reported by 56%, 57%, 58% and 53%, respectively. Of those who had attended other VATS courses previously, 87% preferred the training from this high-volume course. High-volume intensive observership training at an ultra-high-volume centre may improve VATS proficiency in a short period of time, and may provide a time-efficient modality for future thoracic surgical training.

    OBJECTIVES: To compare the scar outcome of video-assisted parathyroidectomy (VAP) with traditional bilateral cervical exploration (BCE) using previously validated scar assessment scales, and to examine the feasibility of introducing VAP into a general otolaryngology-head and neck practice. DESIGN: A retrospective review of medical records from a prospectively obtained database of patients and long-term follow-up of scar analysis. PATIENTS: The records of 60 patients undergoing parathyroidectomy were reviewed: 29 patients underwent VAP and 31 patients underwent an open procedure with BCE. The groups were matched for age and sex. A total of 46 patients were followed up to assess scar outcome. MAIN OUTCOME MEASURES: The primary outcome was a comparison of patient and observer scar satisfaction between VAP and traditional BCE using validated scar assessment tools: the Patient Scar Assessment Scale and the Manchester Scar Scale. The secondary outcomes were to retrospectively evaluate our results with VAP and to assess the suitability of introducing this technique into a general otolaryngology-head and neck practice. RESULTS: The average scar length in the VAP group was 1.7 cm, and the average scar length in the BCE group was 4.3 cm. The patients in the BCE group scored higher than the patients in the VAP group on the Manchester Scar Scale (P < .01) and on the Patient and Observer Scar Scales (P = .02), indicating a worse scar outcome. The mean operative time in the VAP group was 41 minutes compared with 115 minutes in the open procedure BCE group. There was no difference between the 2 groups in terms of postoperative complications. CONCLUSIONS: Video-assisted parathyroidectomy is a safe and feasible procedure in the setting of a general otolaryngology-head and neck practice, with outcomes and complication rates that are comparable to those of traditional bilateral neck exploration. Both patient and observer analysis demonstrated that VAP was associated with a more

    The purpose of this research is to compare liposomal bupivacaine and bupivacaine/epinephrine for intercostal blocks related to analgesic use and length of stay following video-assisted thoracoscopic wedge resection. A retrospective study of patients undergoing video-assisted thoracoscopic wedge resection from 2010 to 2015 was performed. We selected patients who stayed longer than 24 h in hospital. Primary outcomes were length of stay and postoperative analgesic use at 12-h intervals from 24 to 72 h. Intercostal blocks were performed with liposomal bupivacaine in 62 patients and bupivacaine/epinephrine in 51 patients. A Wilcoxon signed-rank test evaluated differences in median postoperative analgesic use and length of stay. Those who received liposomal bupivacaine consumed fewer analgesics than those who received bupivacaine/epinephrine, with a statistically significant difference from 24 to 36 h (20.25 vs 45.0 mg; P  = 0.0059) and from 60 to 72 h postoperatively (15.0 vs 33.75 mg; P  = 0.0350). In patients who stayed longer than 72 h, the median cumulative analgesic consumption in those who received liposomal bupivacaine was statistically significantly lower than those who received bupivacaine/epinephrine (120.0 vs 296.5 mg; P  = 0.0414). Median length of stay for the liposomal bupivacaine and bupivacaine/epinephrine groups were 45:05 h and 44:29 h, respectively. There were no adverse events related to blocks performed with liposomal bupivacaine. Thoracic surgery patients who have blocks performed with liposomal bupivacaine require fewer analgesics postoperatively. This may decrease complications related to poor pain control and decrease side effects related to narcotic use in our patient population. © The Author 2017.

    We describe the technique, the benefits and the drawbacks of an original video-assisted thymectomy (VAT), performed through an inframammary cosmetic incision and median sternotomy in myasthenia gravis (MG) patients. This procedure is clinically valuable and cosmetically satisfactory so as to be very well accepted by patients, especially by young women. Minimal-access thymectomy has become increasingly popular as surgical treatment for patients with nonthymomatous myasthenia gravis because of its comparable efficacy, safety, and lesser degree of tissue trauma with conventional open surgery. We report a review/interview of 180 MG patients treated between 1993 and 2005. According to Myasthenia Gravis Foundation of America (MGFA), complete stable remission (CSR) and pharmacologic remission (PR) were calculated at the end of a minimal period of 12 months. A clinical remission was obtained in 41.1% (CR 27.8%, PR 13.3%), who had been followed for at least 12 months from surgery. 95% of these patients judged their cosmetic results to be excellent or good. Thymectomy in MG video-assisted infra-mammary cosmetic incision has shown to be a useful surgical approach as demonstrated by the good functional and very good aesthetic results, associated with a very low morbidity and no mortality.

    The current system of surgical education is facing many challenges in terms of time efficiency, costs, and patient safety. Training using simulation is an emerging area, mostly based on the experience of other high-risk professions like aviation. The goal of simulation-based training in surgery is to develop not only technical but team skills. This learning environment is stress-free and safe, allows standardization and tailoring of training, and also objectively evaluate performances. The development of simulation training is straightforward in endourology, since these procedures are video-assisted and the low degree of freedom of the instruments is easily replicated. On the other hand, these interventions necessitate a long learning curve, training in the operative room is especially costly and risky. Many models are already in use or under development in all fields of video-assisted urologic surgery: ureteroscopy, percutaneous surgery, transurethral resection of the prostate, and laparoscopy. Although bench models are essential, simulation increasingly benefits from the achievements and development of computer technology. Still in its infancy, virtual reality simulation will certainly belong to tomorrow's teaching tools.

    Video-assisted anal fistula treatment (VAAFT) is a novel minimally invasive and sphincter-saving technique to treat complex anal fistulas described by Meinero in 2006. An enterocutaneous fistula is an abnormal communication between the bowel and the skin. Most cases are secondary to surgical complications, and managing this condition is a true challenge for surgeons. Postoperative fistulas account for 75-85% of all enterocutaneous fistulas. The aim of paper was to devise a minimally invasive technique to treat enterocutaneous fistulas. We used the same principles of VAAFT applied to other conditions, combining endoluminal vision of the tract with colonoscopy to identify the internal opening. We present a case of a 78-year-old woman who was subjected to a total colectomy for cecum and sigmoid synchronous adenocarcinoma. The postoperative course was complicated with an enterocutaneous fistula, treated with conservative measures, which recurred during follow-up. We performed video-assisted fistula treatment using a fistuloscope combined with a colonoscope. Once we identified the fistula tract, we performed cleansing and destruction of the tract, applied synthetic cyanoacrylate and sealed the internal opening with clips through an endoluminal approach. The patient was discharged 5 days later without complications. Two months later the wound was completely healed without evidence of recurrence. This procedure represents an alternative treatment for enterocutaneous fistula using a minimally invasive technique, especially in selected patients not able to undergo major surgery.

    The societies of thoracic surgery are working to incorporate simulation and competency-based assessment into specialty training. One challenge is the development of a simulation-based test, which can be used as an assessment tool. The study objective was to establish validity evidence for a virtual reality simulator test of a video-assisted thoracoscopic surgery (VATS) lobectomy of a right upper lobe. Participants with varying experience in VATS lobectomy were included. They were familiarized with a virtual reality simulator (LapSim ® ) and introduced to the steps of the procedure for a VATS right upper lobe lobectomy. The participants performed two VATS lobectomies on the simulator with a 5-min break between attempts. Nineteen pre-defined simulator metrics were recorded. Fifty-three participants from nine different countries were included. High internal consistency was found for the metrics with Cronbach's alpha coefficient for standardized items of 0.91. Significant test-retest reliability was found for 15 of the metrics (p-values 50 VATS lobectomies performed). A pass/fail level defined as approximately one standard deviation from the mean metric scores for experienced surgeons passed none of the novices (0 % false positives) and failed four of the experienced surgeons (29 % false negatives). This study is the first to establish validity evidence for a VATS right upper lobe lobectomy virtual reality simulator test. Several simulator metrics demonstrated significant differences between novices and experienced surgeons and pass/fail criteria for the test were set with acceptable consequences. This test can be used as a first step in assessing thoracic surgery trainees' VATS lobectomy competency.

    Safety in the operating room is dependent on the team's non-technical skills. The importance of non-technical skills appears to be different for minimally invasive surgery as compared with open surgery. The aim of this study was to identify which non-technical skills are perceived by team members to be most important for patient safety, in the setting of video-assisted thoracoscopic surgery (VATS) lobectomy. This was an explorative, semistructured interview-based study with 21 participants from all four thoracic surgery centers in Denmark that perform VATS lobectomy. Data analysis was deductive, and directed content analysis was used to code the text into the Oxford Non-Technical Skills system for evaluating operating teams' non-technical skills. The most important non-technical skills described by the VATS teams were planning and preparation, situation awareness, problem solving, leadership, risk assessment, and teamwork. These non-technical skills enabled the team to achieve shared mental models, which in turn facilitated their efforts to anticipate next steps. This was viewed as important by the participants as they saw VATS lobectomy as a high-risk procedure with complementary and overlapping scopes of practice between surgical and anesthesia subteams. This study identified six non-technical skills that serve as the foundation for shared mental models of the patient, the current situation, and team resources. These findings contribute three important additions to the shared mental model construct: planning and preparation, risk assessment, and leadership. Shared mental models are crucial for patient safety because they enable VATS teams to anticipate problems through adaptive patterns of both implicit and explicit coordination.

    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 in patients undergoing open colorectal surgery. Since then, the concept of ERAS has been adopted by multiple surgical specialties. The diffusion of video-assisted thoracic surgery lobectomy (VATS-L) sets also the surgical treatment of lung cancer as a new area for ERAS development. In this paper, we present the Italian VATS Group (www.vatsgroup.org) surgical protocol as part of the ERAS clinical pathway belonging to the VATS-L national database. PMID:29629203

  11. Surgeons’ Volume-Outcome Relationship for Lobectomies and Wedge Resections for Cancer Using Video-Assisted Thoracoscopic Techniques

    Full Text Available This study examined the effect of surgeons’ volume on outcomes in lung surgery: lobectomies and wedge resections. Additionally, the effect of video-assisted thoracoscopic surgery (VATS on cost, utilization, and adverse events was analyzed. The Premier Hospital Database was the data source for this analysis. Eligible patients were those of any age undergoing lobectomy or wedge resection using VATS for cancer treatment. Volume was represented by the aggregate experience level of the surgeon in a six-month window before each surgery. A positive volume-outcome relationship was found with some notable features. The relationship is stronger for cost and utilization outcomes than for adverse events; for thoracic surgeons as opposed to other surgeons; for VATS lobectomies rather than VATS wedge resections. While there was a reduction in cost and resource utilization with greater experience in VATS, these outcomes were not associated with greater experience in open procedures.

    Video Assisted Thoracoscopic Surgical (VATS) lobectomy is now considered feasible and safe. Nevertheless, thoracic surgeons need to be aware of dramatic complications that may occur during this procedure and how best to manage them. We report the case of a severe tear of the right pulmonary artery (PA) during elective VATS upper lobectomy, leading to emergency conversion to control the bleeding. Initial arterial repair was performed by end-to-end anastomosis. Early CT angiography showed thrombosis of the right PA due to anastomotic stenosis. We performed emergency pulmonary arterioplasty with a prosthetic patch to save the right lung. A CT scan days after surgical lung salvage confirmed the permeability of the PA and normal vascularization of the two remaining right lobes. We discuss herein this dramatic complication of VATS lobectomy, the viability of the lung after pulmonary arterial thrombosis, and advocate for early postoperative imaging after pulmonary arterioplasty.

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was how video-assisted thoracoscopic surgery (VATS) compares to median sternotomy in the surgical management of patients with myasthenia gravis (MG)? Overall 74 papers were found using the reported search, of which 15 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results are tabulated. We conclude that VATS produces equivalent postoperative mortality and complete stable remission (CSR) rates, with superior results in terms of hospital stay, operative blood loss and patient satisfaction at the expense of a doubling of operative time. Six studies comparing VATS and transsternal sternotomy in non-thymomatous myasthenia gravis (NTMG) patients found VATS to have lower operative blood loss (73.8±70.7 vs. 155.3±91.7 ml; P0.05). One study comparing video-assisted thoracoscopic extended thymectomy to transsternal thymectomy in only thymoma-associated myasthenia gravis (T-MG) patients found equivalent CSR (11.3 vs. 8.7%, P=0.1090) at six-year follow-up. Thymoma recurrence rate (9.64%) was not significantly different (P=0.1523) between the two groups. Eight studies comparing VATS and transsternal approach in mixed T-MG and NTMG patients found a lower hospital stay (1.9±2.6 vs. 4.6±4.2 days, P<0.001), reduced need for postoperative medication (76.5 vs. 35.7%, P=0.022), lower intensive care unit stay (1.5 vs. 3.2 days, P=0.018), greater symptom improvement (100 vs. 77.9%, P=0.019) and better cosmetic satisfaction (100 vs. 83, P=0.042) with VATS. In concordance with NTMG and T-MG alone patient groups, VATS and transsternal methods had equivalent complication rates (23 vs. 19%, P=0.765) with no mortalities in either group. Even though VATS has a longer operative time (268±51 vs. 177±92 min, P<0.05), its improved cosmesis, reduced need

    The aim of the study was to study the feasibility, safety, and efficacy of transesophageal echocardiography-guided intraoperative left ventricular lead placement via a video-assisted thoracoscopic surgery approach in patients with failed conventional biventricular pacing. Twelve patients who could not have the left ventricular lead placed conventionally underwent epicardial left ventricular lead placement by video-assisted thoracoscopic surgery. Eight patients had previous chest surgery (66%). Operative positioning was a modified far lateral supine exposure with 30-degree bed tilt, allowing for groin and sternal access. To determine the optimal left ventricular location for lead placement, the left ventricular surface was divided arbitrarily into nine segments. These segments were transpericardially paced using a hand-held malleable pacing probe identifying the optimal site verified by transesophageal echocardiography. The pacing leads were screwed into position via a limited pericardiotomy. The video-assisted thoracoscopic surgery approach was successful in all patients. Biventricular pacing was achieved in all patients and all reported symptomatic benefit with reduction in New York Heart Association class from III to I-II (P = 0.016). Baseline ejection fraction was 23 ± 3%; within 1-year follow-up, the ejection fraction increased to 32 ± 10% (P = 0.05). The mean follow-up was 566 days. The median length of hospital stay was 7 days with chest tube removal between postoperative days 2 and 5. In patients who are nonresponders to conventional biventricular pacing, intraoperative left ventricular lead placement using anatomical and functional characteristics via a video-assisted thoracoscopic surgery approach is effective in improving heart failure symptoms. This optimized left ventricular lead placement is feasible and safe. Previous chest surgery is no longer an exclusion criterion for a video-assisted thoracoscopic surgery approach.

    2015-11-01

    With many surgical training programmes providing less time for training it can be challenging for trainees to acquire the necessary surgical skills to perform complex video assisted thoracoscopic surgery (VATS) lung resections. Indeed as the utilization of single port operations increases the need to approach the operating theatre with already-existing excellent hand-eye coordination skills increases. We suggest that there are a number of ways that trainees can begin to develop these necessary skills. Firstly, using computer games that involve changing horizons and orientations. Secondly, utilizing box-trainers to practice using the thoracoscopic instruments. Thirdly, learning how essential tools such as the stapler work. Trainees will then be able to progress to meaningfully assisting in theatre and indeed learning how to perform the operation themselves. At this stage is useful to observe expert surgeons whilst they operate-to watch both their technical and non-technical skills. Ultimately, surgery is a learned skill and requires implementation of these techniques over a sustained period of time.

    Uniportal video-assisted thoracoscopic surgery (VATS) lobectomy is an emerging technique for the surgical resection of non-small cell lung cancer (NSCLC). Besides its wide debates on safety and efficacy throughout the world, there were few report on uniportal VATS from the Eastern countries. In this article, we summarized our primary experience on uniportal VATS lobectomy in an Eastern center. From October 2013 till February 2014, 54 consecutive uniportal VATS lobectomy were performed in the Department of Thoracic Surgery, Zhongshan Hospital of Fudan University. Patients' clinical features and operative details were recorded. Post-operatively, the morbidity and mortality were recorded to analyze the safety and efficacy of uniportal VATS lobectomy for NSCLCs. Among the 54 planned uniportal VATS lobectomy, there was one conversion to mini-thoracotomy due to lymph node sticking. Extra ports were required in two patients. The uniportal VATS lobectomy was achieved in 51 out of 54 patients (94.4%). The average operation duration was 122.2±37.5 min (90-160 min). The average volume of estimated blood loss during the operation was 88.8±47.1 mL (50-200 mL). The mean chest tube duration and hospital stay were 3.2±1.9 days and 4.6±2.0 days, respectively. There was no postoperative mortality in this study. Two patients suffered from prolonged air leakage (5 and 7 days), and one atrial fibrillation was observed in this cohort. Based on our primary experience, uniportal VATS lobectomy is a safe and effective procedure for the surgical resection of NSCLCs. The surgical refinements and instrumental improvements would facilitate the technique. Further studies based on larger population are required to determine its benefits towards patients with NSCLCs.

  1. Video-Assisted Thoracoscopic Surgery in Patients With Clinically Resectable Lung Tumors

    Full Text Available To investigate the feasibility of thoracoscopic resection, a pilot study was performed in patients with clinically resectable lung tumors. In 40 patients, Video-assisted thoracic surgery (VATS was performed because of suspicion of malignancy. There were 29 men and 11 women with a median age of 54.8 years (range 18 to 78. Preoperative indications were suspected lung cancer and tumor in 27 patients, assessment of tumor resectability in 7 patients, and probability of metastatic tumors in 6 patients. The final diagnoses in the 27 patients with suspected lung cancer were 12 primary lung cancers, 6 lung metastases, and 9 benign lesions. The success rates for VATS (no conversion to thoracotomy were 1 of 12 (8.3% for resectable stage I lung cancer, 8 of 12 (66.7% for metastatic tumors, and 9 of 9 (100% for benign tumors. With VATS, 6 of 7 patients (85.7%, possible stage III non-small cell lung cancer, an explorative thoracotomy with was avoided, significantly reducing morbidity. The reasons for conversion to thoracotomy were 1 oncological (N2 lymph node dissection and prevention of tumor spillage and 2 technical (inability to locate the nodule, central localization, no anatomical fissure, or poor lung function requiring full lung ventilation. The ultimate diagnoses were 19 lung cancers, 12 metastatic lung tumors, and 9 benign lung tumors. Our data show the limitations of VATS for malignant tumors in general use. These findings, together with the fact that experience in performing thoracoscopic procedures demonstrates a learning curve, may limit the use of thoracoscopic resection as a routine surgical procedure, especially when strict oncological rules are respected.

    Full Text Available Background. The aim of this study was to determine the incidence of pre- and postoperative vomiting in children undergoing a Video-Assisted Gastrostomy (VAG operation. Patients and Methods. 180 children underwent a VAG operation and were subdivided into groups based on their underlying diagnosis. An anamnesis with respect to vomiting was taken from each of the children’s parents before the operation. After the VAG operation, all patients were followed prospectively at one and six months after surgery. All complications including vomiting were documented according to a standardized protocol. Results. Vomiting occurred preoperatively in 51 children (28%. One month after surgery the incidence was 43 (24% in the same group of children and six months after it was found in 40 (22%. There was a difference in vomiting frequency both pre- and postoperatively between the children in the groups with different diagnoses included in the study. No difference was noted in pre- and postoperative vomiting frequency within each specific diagnosis group. Conclusion. The preoperative vomiting symptoms persisted after the VAG operation. Neurologically impaired children had a higher incidence of vomiting than patients with other diagnoses, a well-known fact, probably due to their underlying diagnosis and not the VAG operation. This information is useful in preoperative counselling.

    Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg 2  cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.

  6. The role of diagnostic VATS in penetrating thoracic injuries

    Directory of Open Access Journals (Sweden)

    2006-10-01

    Full Text Available Abstract Background Penetrating chest injuries account for 1–13% of thoracic trauma hospital admissions and most of these are managed with a conservative approach. Nevertheless, 18–30% of cases managed only with tube thoracostomy have residual clotted blood, considered the major risk factor for the development of fibrothorax and empyema. In addition, 4–23% of chest injury patients present persistent pneumothorax and 15–59% present an injury to the diaphragm, which is missed in 30% of cases. In order to make a correct diagnosis, reduce the number of missed injuries, chronic sequelae and late mortality we propose performing surgical exploration of all patients with a penetrating injury of the pleural cavity. Methods 1270 patients who sustained thoracic trauma were admitted to our hospital between 1994 and 2004. Of these, 16 patients had penetrating injuries: thirteen were surgically explored by means of Video Assisted Thoracic Surgery (VATS, and 3 with thoracotomy due to hemodynamic instability or suspected lesion of the heart or great vessels. Results In the 13 patients who underwent VATS, 5 injuries to the diaphragm, 3 lesions to an intercostal artery, and 1 lesion to the diaphragmatic artery were detected. In 12 of these patients a laceration of the pulmonary parenchyma was also present. A conversion to thoracotomy was necessary due to a broad laceration of the diaphragm and due to hemostasis of an intercostal artery. In all but one case, which was later converted, diagnostic imaging missed the diagnosis of laceration of the diaphragm. There was no intra- or postoperative mortality, and average hospital stay was five days. Conclusion VATS is a safe and effective way to diagnose and manage penetrating thoracic injuries, and its extensive use leads to a reduction in the number of missed, potentially fatal lesions as well as in chronic sequelae.

    2010-12-01

    We measured lung function before and after video-assisted thoracoscopic apical bullectomy and talc poudrage in patients with spontaneous pneumothoraces. Seventy-two patients were prospectively followed up for 12 months. The indications for surgery were recurrent pneumothoraces (n = 58), bilateral pneumothoraces (n = 8), and persistent air leak (n = 6). There were 46 males and 26 females with mean age of 29 years (range 15-61 years). The results were analyzed using paired t tests. There were no recurrences. There were 4 complications (5.6%): 1 wound infection, 1 case of pneumonia, and 2 persistent air leaks each lasting 1 week. There were no conversions to open surgery. Preoperative and 6-month pulmonary function test results were available on 41 patients, and 35 patients completed 12-month pulmonary function tests. Twelve-month values (mean percent ± SD) were as follows: Forced expiratory volume in 1 second fell from 95 ± 19 to 89 ± 16 (P = .02); forced expiratory volume in 1 second/forced vital capacity ratio was unchanged, 95 ± 12 versus 94 ± 13 (P = .9); total lung capacity fell from 106 ± 19 to 98 ± 12 (P = 0.002); vital capacity fell from 100 ± 22 to 96 ± 16 (P = .05); residual volume fell from 126 ± 32 to 107 ± 29 (P = .002); and diffusion capacity for carbon monoxide corrected for alveolar volume was unchanged, 88 ± 15 versus 91 ± 17 (P = .07). Flow rates and diffusion capacities were preserved, but lung volumes were slightly reduced at 1 year. Video-assisted thoracoscopic apical bullectomy and talc poudrage is an effective treatment for spontaneous pneumothoraces with a low complication rate and recurrence rate and only minor changes in pulmonary function at 1 year.

    Thymectomy considered as a standard procedure in treatment of all the steps of myasthenia gravis. Video-assisted thoracoscopic surgery (VATS) thymectomy is one of the minimally invasive procedures that because of the short duration of hospitalization, less postoperative pain, and scar after surgery, nowadays it is replaced the traditional methods of surgery for patients with myasthenia gravis, but there are still differences and concerns. The aim of this study was to compare outcomes of two different techniques of surgery, VATS versus transsternal (TS) in the treatment of myasthenia gravis. In this pilot study, 42 patients with myasthenia gravis and without a thymus tumor were evaluated based on Myasthenia Gravis Foundation of America classification and drug consumption. Then, they randomly underwent two different techniques of surgery: VATS versus TS. Patients were evaluated based on preoperative and postoperative variables. Duration of intensive care unit stay and hospitalization has been reduced in patients who underwent VATS thymectomy operation technique. In addition, duration of surgical procedure has been reduced significantly in these patients. These patients have less blood loss during surgery compared with TS group. The Myasthenia Gravis Foundation of America postoperative status in VATS thymectomy revealed that the number of patients with complete stable remission was higher and number of persons remained unchanged was lower in this group. VATS thymectomy is a safe and appropriate approach comparing with traditional methods such as TS thymectomy for patients with myasthenia gravis. This method has better results after surgery and can be used as a minimally invasive alternative method instead of TS thymectomy.

    Minimally invasive cardiovascular procedures have been progressively used in heart surgery. To describe the techniques and immediate results of minimally invasive procedures in 5 years. Prospective and descriptive study in which 102 patients were submitted to minimally invasive procedures in direct and video-assisted forms. Clinical and surgical variables were evaluated as well as the in hospital follow-up of the patients. Fourteen patients were operated through the direct form and 88 through the video-assisted form. Between minimally invasive procedures in direct form, 13 had aortic valve disease. Between minimally invasive procedures in video-assisted forms, 43 had mitral valve disease, 41 atrial septal defect and four tumors. In relation to mitral valve disease, we replaced 26 and reconstructed 17 valves. Aortic clamp, extracorporeal and procedure times were, respectively, 91,6 ± 21,8, 112,7 ± 27,9 e 247,1 ± 20,3 minutes in minimally invasive procedures in direct form. Between minimally invasive procedures in video-assisted forms, 71,6 ± 29, 99,7 ± 32,6 e 226,1 ± 42,7 minutes. Considering intensive care and hospitalization times, these were 41,1 ± 14,7 hours and 4,6 ± 2 days in minimally invasive procedures in direct and 36,8 ± 16,3 hours and 4,3 ± 1,9 days in minimally invasive procedures in video-assisted forms procedures. Minimally invasive procedures were used in two forms - direct and video-assisted - with safety in the surgical treatment of video-assisted, atrial septal defect and tumors of the heart. These procedures seem to result in longer surgical variables. However, hospital recuperation was faster, independent of the access or pathology

    In recent years, the search for a less invasive and thus, less painful approach has driven technical innovation in modern thoracic surgery. In this context, subxiphoid uniportal approach has emerged as an alternative to avoid intercostal space manipulation and decrease postoperative pain and intercostal nerve chronic impairment. Subxiphoid uniportal major lung resections have been safe and effective procedures when performed by experienced surgeons even in complex cases or unexpected intraoperative situations. We present six of these surgical scenarios such as big tumors, incomplete or absent fissures, hilar calcified lymph nodes, active bleeding and massive adhesions to show the feasibility of subxiphoid approach to manage even these conditions.

    2014-09-01

    Objective : The learning process for intraoral procedures is arguably more difficult than for other surgical procedures because of the assistant's severely limited visibility. Consequently, trainees may not be able to adequately see and follow all steps of the procedure, and attending surgeons may be less willing to entrust trainees with critical portions of the procedure. In this report, we propose a video-assisted approach to intraoral procedures that improves lighting, visibility, and potential for effective education and training. Design : Technical report (idea/innovation). Setting : Tertiary referral hospital. Patients : Children with cleft palate and velopharyngeal insufficiency requiring surgery. Interventions : Video-assisted palatoplasty, sphincteroplasty, and pharyngoplasty. Main Outcome Measures : Qualitative and semiquantitative educational outcomes, including learner perception regarding "real-time" (video-assisted surgery) and "non-real-time" (video-library-based) surgical education. Results : Trainees were strongly in favor of the video-assisted modality in "real-time" surgical training. Senior trainees identified more opportunities in which they had been safely entrusted to perform critical portions of the procedure, corresponding with satisfaction with the learning process scores, and they showed greater comfort/confidence scores related to performing the procedure under supervision and alone. Conclusions : Adoption of the video-assisted approach can be expected to markedly improve the learning curve for surgeons in training. This is now standard practice at our institution. We are presently conducting a full educational technology assessment to better characterize the effect on knowledge acquisition and technical improvement.

    Full Text Available Background and objective Post-operation management of minimally invasive thoracic surgery is similar to that of open surgery, especially on the drainage tube of the chest. The aim of this study is to compare the advantages of using 16 F versus 28 F chest tubes in video-assisted thoracoscopic surgery (VATS lobectomy of lung cancer. Methods Data from 163 patients (February-May 2014 who underwent VATS lobectomy of lung cancer with insertion of one chest drain (16 F or 28 F were analyzed. The following post-operative data were evaluated: primary healing of tube incision, CXR abnormalities (pneumothorax, fluid, atelectasis, subcutaneous emphysema, and hematoma, drainage time, new drain insertion, and wound healing at the site of insertion. Results A total of 75 patients received 28 F chest tubes, and 88 patients received 16 F chest tubes. Both groups were similar in age, gender, comorbidities, and pathological evaluation of resection specimens. After adjustment, no statistically significant difference was found between the two groups in relation to tube-related complications including residual pneumothoraces (4.00% vs 4.44%; P=0.999, subcutaneous emphysema (8.00% vs 6.67%; P=0.789, retained hemothorax (0 vs 41%, P=0.253, and drainage time [(28.4±16.12 h vs (22.1±11.8 h; P=0.120] The average total drainage volume and rrhythmia rates of the 16 F group [(365±106 mL, 14.67%] was less than that of the 28 F group [(665±217 mL, 4.5%; P=0.030, P=0.047]. The rates of primary healing at the site of insertion in the 16 F group (95.45% was higher than that in the 28 F group (77.73%, P=0.039. A significant difference was found on the post-operative length of stay of the two groups [(4.23±0.05 d vs (4.57±0.16 d, P=0.078]. Conclusion The use of 16 F chest tube for VATS lobectomy of patients with lung cancer did not affect the clinically relevant outcomes tested. However, 16 F chest tube facilitated faster wound healing at the site of insertion.

    This study aimed to retrospectively evaluate the use of sugammadex in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy. Data were obtained from medical record review of patients who underwent VATS lobectomy from January 2013 to November 2014. Fifty patients were divided into two groups: the sugammadex group (group S, n = 19) was administered sugammadex 2 mg/kg, while the pyridostigmine group (group P, n = 31) received pyridostigmine 20 mg with glycopyrrolate 0.2 mg or atropine 0.5 mg. The primary endpoint measure was the overall incidence of postoperative pulmonary complications including prolonged air leak, pneumonia, and atelectasis. The secondary endpoint measures were the length of postoperative hospital stay and duration of chest tube insertion. The overall incidence of postoperative pulmonary complications in patients in group S was significantly lower compared with that of group P (5 [26.3%] vs. 17 [54.8%]; P = 0.049). Also, the durations of chest tube insertion (5.0 [4.0-7.0] vs. 7.0 [6.0-8.0] days; P = 0.014) and postoperative hospital stay (8.0 [8.0-10.0] vs. 10.0 [9.0-11.0] days; P = 0.019) were shorter in group S compared with group P. Administration of sugammadex was associated reduced with postoperative pulmonary complications (OR: 0.22; 95% CI: 0.05-0.87; P = 0.031). The use of sugammadex, compared with pyridostigmine, showed a significantly reduced overall incidence of postoperative pulmonary complications and decreased duration of chest tube use and postoperative hospital stay in patients undergoing VATS lobectomy, suggesting that sugammadex might be helpful in improving clinical outcomes in such patients.

    Full Text Available Background and objective The aim of this study is to assess the effect of video-assisted thoracoscopic surgery (VATS and video-assisted mini-thoracotomy (VAMT in the treatment of non-small cell lung cancer (NSCLC. Methods We searched PubMed, EMbase, CNKI, VIP and ISI Web of Science to collect randomized controlled trials (RCTs of VATS versus VAMT for NSCLC. Each database was searched from May 2006 to May 2016. Two reviewers independently assessed the quality of the included studies and extracted relevant data, using RevMan 5.3 meta-analysis software. Results We finally identified 13 RCTs involving 1,605 patients. There were 815 patients in the VATS group and 790 patients in the VAMT group. The results of meta-analysis were as follows: statistically significant difference was found in the harvested lymph nodes (SMD=-0.48, 95%CI: -0.80--0.17, operating time (SMD=13.56, 95%CI: 4.96-22.16, operation bleeding volume (SMD=-33.68, 95%CI: -45.70--21.66, chest tube placement time (SMD=-1.05, 95%CI: -1.48--0.62, chest tube drainage flow (SMD=-83.69, 95%CI: -143.33--24.05, postoperative pain scores (SMD=-1.68, 95%CI: -1.98--1.38 and postoperative hospital stay (SMD=-2.27, 95%CI: -3.23--1.31. No statistically significant difference was found in postoperative complications (SMD=0.83, 95%CI: 0.54-1.29 and postoperative mortality (SMD=0.95, 95%CI: 0.55-1.63 between videoassisted thoracoscopic surgery lobectomy and video-assisted mini-thoracotomy lobectomy in the treatment of NSCLC. Conclusion Compared with video-assisted mini-thoracotomy lobectomy in the treatment of non-small cell lung cancer, the amount of postoperative complications and postoperative mortality were almost the same in video-assisted thoracoscopic lobectomy, but the amount of harvested lymph nodes, operating time, blood loss, chest tube drainage flow, and postoperative hospital stay were different. VATS is safe and effective in the treatment of NSCLC.

    Video-assisted thoracoscopic surgery (VATS) using a single incision (uniportal) may result in better pain control, earlier mobilization and shorter hospital stays. Here, we review the safety and efficiency of our initial experience with uniportal VATS and evaluate our learning curve. We conducted a retrospective review of uniportal VATS using a prospectively maintained departmental database and analyzed patients who had undergone a lung anatomic resection separately from patients who underwent other resections. To assess the learning curve, we compared the first 10 months of the study period with the second 10 months. From January 2014 to August 2015, 250 patients underwent intended uniportal VATS, including 180 lung anatomic resections (72%) and 70 other resections (28%). Lung anatomic resection was successfully completed using uniportal VATS in 153 patients (85%), which comprised all the anatomic segmentectomies (29 patients), 80% (4 of 5) of the pneumonectomies and 82% (120 of 146) of the lobectomies attempted. The majority of lung anatomic resections that required conversion to thoracotomy occurred in the first half of our study period. Seventy patients underwent other uniportal VATS resections. Wedge resections were the most common of these procedures (25 patients, 35.7%). Although 24 of the 70 patients (34%) required the placement of additional ports, none required conversion to thoracotomy. Uniportal VATS was safe and feasible for both standard and complex pulmonary resections. However, when used for pulmonary anatomic resections, uniportal VATS entails a steep learning curve.

    : Objective: To compare the safety/efficacy of the robotic-assisted lobectomy/segmentectomy (RAL/S) with the video-assisted lobectomy/segmentectomy (VAL/S) for radical lung cancer resection. It remains uncertain whether the newly developed RAL/S is comparable with the VAL/S. A comprehensive search of online databases was performed. Perioperative outcomes were synthesized. Cumulative meta-analysis was performed to evaluate the temporal trend of pooled outcomes. Specific subgroups (propensity score matching studies, pure lobectomy studies) were examined. Analysis of 14 studies including a total of 7438 patients was performed. RAL/S was performed on 3239 patients, whereas the other 4199 patients underwent VAL/S. The 30-day mortality [0.7% vs 1.1%; odds ratio (OR) 0.53, P = 0.045] and conversion rate to open surgery (10.3% vs 11.9%; OR 0.57, P < 0.001) were significantly lower in patients who underwent RAL/S than VAL/S. Meanwhile, the postoperative complications (27.5% vs 28.2%; OR 0.95, P = 0.431), operation time [176.63 vs 162.74 min; standardized mean difference (SMD) 0.30, P = 0.086], duration of hospitalization (4.90 vs 5.23 days; SMD -0.08, P = 0.292), days to tube removal (4.10 vs 3.53 days; SMD 0.25, P = 0.120), retrieved lymph node (11.96 vs 10.67; SMD 0.46, P = 0.381), and retrieved lymph node station (4.98 vs 4.32; SMD 0.83, P = 0.261) were similar between the 2 groups. The cumulative meta-analyses suggested that the relative effects between 2 groups have already stabilized. All outcomes of subgroup and overall analyses were similar. This up-to-date meta-analysis confirms that RAL/S is a feasible and safe alternative to VAL/S for radical resection of lung cancer. Future studies should focus on the long-term benefits and cost effectiveness of RAL/S compared with VAL/S.

    Latching is an important process of breastfeeding and should be taught and practiced by the postpartum mother. The objective is to compare latching outcomes between video-assisted and routine teaching methods among postpartum women. A randomized controlled trial was conducted. Postpartum women who had deliveries without complications were randomized into two groups: 14 cases in the video-assisted teaching group and 14 cases in a routine teaching group. In the first group, the mothers were taught breastfeeding benefits, latching methods, and breastfeeding positions and practiced breastfeeding in a controlled setting for a 30-minute period and watched a 6-minute video with consistent content. In the second group, the mothers were taught a normal 30-minute period and then practiced breastfeeding. In both groups, Latching on, Audible swallowing, the Type of nipples, Comfort, and Help (LATCH) scores were assessed at 24-32 and 48-56 hours after the breastfeeding teaching modals. Demographic data and LATCH scores were collected and analyzed. There were no statistically significant differences in the mothers' ages, occupations, marital status, religion, education, income, infants' gestational age, body mass index, nipple length, route of delivery, and time to first latching between the video-assisted and routine breastfeeding teaching groups. First and second LATCH score assessments had shown no significant differences between both breastfeeding teaching groups. The video-assisted breastfeeding teaching did not improve latching outcomes when it was compared with routine teaching.

    Video-assisted thoracoscopic surgery (VATS) has been widely accepted as a minimally invasive surgery for treatment of early-stage lung cancer. However, various VATS approaches are available. In patients with lung cancer, VATS should achieve not only minimal invasiveness but also safety and oncological clearance. In this article, we introduce our method of VATS lobectomy.

    2018-02-01

    Full Text Available The main goal of enhanced recovery program after thoracic surgery is to minimize stress response, reduce postoperative pulmonary complications, and improve patient outcome, which will in addition decrease hospital stay and reduce hospital costs. As minimally invasive technique, video-assisted thoracoscopic surgery represents an important element of enhanced recovery program in thoracic surgery. Anesthetic management during preoperative, intraoperative and postoperative period is essential for the enhanced recovery. In the era of enhanced recovery protocols, non-intubated thoracoscopic procedures present a step forward. This article focuses on the key elements of the enhanced recovery program in thoracic surgery. Having reviewed recent literature, the authors highlight potential procedures and techniques that might be incorporated into the program.

    A case of temporary quadriplegia following a continuous thoracic paravertebral block in an adult patient scheduled for video-assisted thoracoscopy is presented. An 18-gauge Tuohy needle was inserted under direct vision by the surgeon but the tip of the catheter was not localized. Postoperatively, the patient developed temporary quadriplegia 90 minutes after the start of a continuous infusion of ropivacaine 0.2%. Imaging studies showed that the catheter was localized in the intrathecal space. Copyright © 2012 Elsevier Inc. All rights reserved.

    A major pathogenic factor for catamenial pneumothorax is thoracic endometriosis. However, thoracic endometriosis-related pneumothorax (TERP) can develop as either catamenial or non-catamenial pneumothorax (CP). Therefore, the aim of this study was to elucidate the clinical differences between catamenial and non-catamenial TERP. The clinical and pathological data in female patients who underwent video-assisted thoracoscopic surgery at the Pneumothorax Research Center during an 8-year period were retrospectively reviewed. This study included 150 female patients with surgico-pathologically confirmed TERP. The subjects were divided into two groups, those having all of the pneumothorax episodes in the catamenial period (CP group) and those who did not (non-CP group). We compared the clinical characteristics and surgico-pathological findings between these two groups. Of the 150 TERP patients, 55 (36.7%) were classified in the CP group, and 95 (63.3%) in the non-CP group. In regard to the locations of endometriosis, all TERP patients had diaphragmatic endometriosis, while pleural implantation was recognized in 34 of the 55 (61.8%) patients in the CP group and 42 of the 95 (44.2%) patients in the non-CP group (P pneumothorax episodes. © 2015 Asian Pacific Society of Respirology.

    Large retrospective series have indicated lower rates of cN0 to pN1 nodal upstaging after video-assisted thoracic surgery (VATS) compared with open resections for Stage I non-small-cell lung cancer (NSCLC). The objective of our multicentre study was to investigate whether the presumed lower rate of N1 upstaging after VATS disappears after correction for central tumour location in a multivariable analysis. Consecutive patients operated for PET-CT based clinical Stage I NSCLC were selected from prospectively managed surgical databases in 11 European centres. Central tumour location was defined as contact with bronchovascular structures on computer tomography and/or visibility on standard bronchoscopy. Eight hundred and ninety-five patients underwent pulmonary resection by VATS (n = 699, 9% conversions) or an open technique (n = 196) in 2014. Incidence of nodal pN1 and pN2 upstaging was 8% and 7% after VATS and 15% and 6% after open surgery, respectively. pN1 was found in 27% of patients with central tumours. Less central tumours were operated on by VATS compared with the open technique (12% vs 28%, P < 0.001). Logistic regression analysis showed that only tumour location had a significant impact on N1 upstaging (OR 6.2, confidence interval 3.6-10.8; P < 0.001) and that the effect of surgical technique (VATS versus open surgery) was no longer significant when accounting for tumour location. A quarter of patients with central clinical Stage I NSCLC was upstaged to pN1 at resection. Central tumour location was the only independent factor associated with N1 upstaging, undermining the evidence for lower N1 upstaging after VATS resections. Studies investigating N1 upstaging after VATS compared with open surgery should be interpreted with caution due to possible selection bias, i.e. relatively more central tumours in the open group with a higher chance of N1 upstaging. © The Author 2017.

    The aims of this study were to develop virtual reality simulation software for video-assisted thoracic surgery (VATS) lobectomy, to explore the opinions of thoracic surgeons concerning the VATS lobectomy simulator and to test the validity of the simulator metrics. Experienced VATS surgeons worked with computer specialists to develop a VATS lobectomy software for a virtual reality simulator. Thoracic surgeons with different degrees of experience in VATS were enrolled at the 22nd meeting of the European Society of Thoracic Surgeons (ESTS) held in Copenhagen in June 2014. The surgeons were divided according to the number of performed VATS lobectomies: novices (0 VATS lobectomies), intermediates (1-49 VATS lobectomies) and experienced (>50 VATS lobectomies). The participants all performed a lobectomy of a right upper lobe on the simulator and answered a questionnaire regarding content validity. Metrics were compared between the three groups. We succeeded in developing the first version of a virtual reality VATS lobectomy simulator. A total of 103 thoracic surgeons completed the simulated lobectomy and were distributed as follows: novices n = 32, intermediates n = 45 and experienced n = 26. All groups rated the overall user realism of the VATS lobectomy scenario to a median of 5 on a scale 1-7, with 7 being the best score. The experienced surgeons found the graphics and movements realistic and rated the scenario high in terms of usefulness as a training tool for novice and intermediate experienced thoracic surgeons, but not very useful as a training tool for experienced surgeons. The metric scores were not statistically significant between groups. This is the first study to describe a commercially available virtual reality simulator for a VATS lobectomy. More than 100 thoracic surgeons found the simulator realistic, and hence it showed good content validity. However, none of the built-in simulator metrics could significantly distinguish between novice, intermediate

    Functional results of index pollicisation are usually assessed by the clinical score of Percival. This score is based on elementary hand movements and does not reflect the function of the neo thumb in daily life activities. The aim of this study was to develop a new video-assisted scoring system based on daily life activities to assess index pollicisation functional outcomes. Twenty-two consecutive children, operated between 1998 and 2012, were examined with a mean of 77 months after surgery. The mean age at surgery was 34 months. Post-operative results were evaluated by a new video-assisted 14-point scoring system consisting of seven basic tasks that are frequently used in daily activities. The series of tasks was performed both on the request of the examiner and in real-life conditions with the use of a hidden camera. Each video recording was examined by three different examiners. Each examiner rated the video recordings three times, with an interval of one week between examinations. Inter- and intra-observer agreements were calculated. Inter- and intra-observer agreements were excellent both on request (κ = 0.87 [0.84-0.97] for inter-observer agreement and 0.92 [0.82-0.98] for intra-observer agreement) and on hidden camera (κ = 0.83 [0.78-0.91] for inter-observer agreement and 0.89 [0.83-0.96] for intra-observer agreement). The results were significantly better on request than on hidden camera (p = 0.045). The correlation between the video-assisted scoring system and the Percival score was poor. The video-assisted scoring system is a reliable tool to assess index pollicisation functional outcomes. The scoring system on hidden camera is more representative of the neo thumb use in daily life complex movements. Level IV.

    To develop a clinically risk-adjusted financial model to estimate the cost associated with a video-assisted thoracoscopic surgery (VATS) lobectomy programme. Prospectively collected data of 236 VATS lobectomy patients (August 2012-December 2013) were analysed retrospectively. Fixed and variable intraoperative and postoperative costs were retrieved from the Hospital Accounting Department. Baseline and surgical variables were tested for a possible association with total cost using a multivariable linear regression and bootstrap analyses. Costs were calculated in GBP and expressed in Euros (EUR:GBP exchange rate 1.4). The average total cost of a VATS lobectomy was €11 368 (range €6992-€62 535). Average intraoperative (including surgical and anaesthetic time, overhead, disposable materials) and postoperative costs [including ward stay, high dependency unit (HDU) or intensive care unit (ICU) and variable costs associated with management of complications] were €8226 (range €5656-€13 296) and €3029 (range €529-€51 970), respectively. The following variables remained reliably associated with total costs after linear regression analysis and bootstrap: carbon monoxide lung diffusion capacity (DLCO) 0.05) in 86% of the samples. A hypothetical patient with COPD and DLCO less than 60% would cost €4270 more than a patient without COPD and with higher DLCO values (€14 793 vs €10 523). Risk-adjusting financial data can help estimate the total cost associated with VATS lobectomy based on clinical factors. This model can be used to audit the internal financial performance of a VATS lobectomy programme for budgeting, planning and for appropriate bundled payment reimbursements. © The Author 2015.

    Knowledge about the cost of open, video-assisted thoracoscopic (VATS), or robotic lung resection and drivers of cost is crucial as the cost of care comes under scrutiny. This study aims to define the cost of anatomic lung resection and evaluate potential cost-saving measures. A retrospective review of patients who had anatomic resection for early stage lung cancer, carcinoid, or metastatic foci between 2008 and 2012 was performed. Direct hospital cost data were collected from 10 categories. Capital depreciation was separated for the robotic and VATS cases. Key costs were varied in a sensitivity analysis. In all, 184 consecutive patients were included: 69 open, 57 robotic, and 58 VATS. Comorbidities and complication rates were similar. Operative time was statistically different among the three modalities, but length of stay was not. There was no statistically significant difference in overall cost between VATS and open cases (Δ = $1,207) or open and robotic cases (Δ = $1,975). Robotic cases cost $3,182 more than VATS (p depreciation. The main opportunities to reduce cost in open cases were the intensive care unit, respiratory therapy, and laboratories. Lowering operating time and supply costs were targets for VATS and robotic cases. VATS is the least expensive surgical approach. Robotic cases must be shorter in operative time or reduce supply costs, or both, to be competitive. Lessening operating time, eradicating unnecessary laboratory work, and minimizing intensive care unit stays will help decrease direct hospital costs.

    To describe and assess the localization of small peripheral pulmonary nodules prior to video-assisted thoracoscopic surgical (VATS) resection using the implantation of microcoils. Ninety-two patients with 101 pulmonary nodules underwent computed tomography (CT)-guided implantation of microcoils proximal to each nodule. Patients were randomly assigned to undergo entire microcoil or leaving-microcoil-end implantations. The complications and efficacy of the two implantation methods were evaluated. VATS resection of lung tissue containing each pulmonary lesion and microcoil were performed in the direction of the microcoil marker. Histopathological analysis was performed for the resected pulmonary lesions. CT-guided microcoil implantation was successful in 99/101 cases, and the placement of microcoils within 1 cm of the nodules was not disruptive. There was no difference in the complications and efficacy associated with the entire implantation method (performed for 51/99 nodules) versus the leaving-microcoil-end implantation method (performed for 48/99 nodules). All nodules were successfully removed using VATS resection. Asymptomatic pneumothorax occurred in 16 patients and mild pulmonary haemorrhage occurred in nine patients. However, none of these patients required further surgical treatment. Preoperative localization of small pulmonary nodules using a refined percutaneous microcoil implantation method was found to be safe and useful prior to VATS resection. (orig.)

    Full Text Available Hemothorax is common in elderly patients following blunt chest trauma. Traditionally, tube thoracostomy is the first choice for managing this complication. The goal of this study was to determine the benefits of this approach in elderly patients with and without an initial tube thoracostomy. Seventy-eight patients aged >65 years with blunt chest trauma and stable vital signs were included. All of them had more than 300 mL of hemothorax, indicating that a tube thoracostomy was necessary. The basic demographic data and clinical outcomes of patients with hemothorax who underwent direct video-assisted thoracoscopic surgery without a tube thoracostomy were compared with those who received an initial tube thoracostomy. Patients who did not receive a thoracostomy had lower posttrauma infection rates (28.6% versus 56.3%, P=0.061 and a significantly shorter length of stay in the intensive care unit (3.13 versus 8.27, P=0.029 and in the hospital (15.93 versus 23.17, P=0.01 compared with those who received a thoracostomy. The clinical outcomes in the patients who received direct VATS were more favorable compared with those of the patients who did not receive direct VATS.

    Medical economics have significant impact on the entire country. The explosion in surgical techniques has been accompanied by questions regarding actual improvements in outcome and cost-effectiveness, such as the da Vinci(®) Surgical System (dVS) compared with conventional video-assisted thoracic surgery (VATS). To establish a medical fee system for robot-assisted thoracic surgery (RATS), which is a system not yet firmly established in Japan. This study examines the cost benefit performance (CBP) based on medical fees compared with VATS and RATS under the Japanese National Health Insurance System (JNHIS) introduced in 2012. The projected (but as yet undecided) price in the JNHIS would be insufficient if institutions have less than even 200 dVS cases per year. Only institutions which perform more than 300 dVS operations per year would obtain a positive CBP with the projected JNHIS reimbursement. Thus, under the present conditions, it is necessary to perform at least 300 dVS operations per year in each institution with a dVS system to avoid financial deficit with current robotic surgical management. This may hopefully encourage a downward price revision of the dVS equipment by the manufacture which would result in a decrease in the cost per procedure.

    The use of low tidal volume during one-lung ventilation (OLV) has been shown to attenuate the incidence of acute lung injury after thoracic surgery. To test the effect of tidal volume during OLV for video-assisted thoracoscopic surgery on the extravascular lung water content index (EVLWI). A randomised, double-blind, controlled study. Single university hospital. Thirty-nine patients scheduled for elective video-assisted thoracoscopic surgery. Patients were randomly assigned to one of three groups (n = 13 per group) to ventilate the dependent lung with a tidal volume of 4, 6 or 8 ml  kg(-1) predicted body weight with I:E ratio of 1:2.5 and PEEP of 5 cm H2O. The primary outcomes were perioperative changes in EVLWI and EVLWI to intrathoracic blood volume index (ITBVI) ratio. Secondary outcomes included haemodynamics, oxygenation indices, incidences of postoperative acute lung injury, atelectasis, pneumonia, morbidity and 30-day mortality. A tidal volume of 4 compared with 6 and 8 ml  kg(-1) after 45 min of OLV resulted in an EVLWI of 4.1 [95% confidence interval (CI) 3.5 to 4.7] compared with 7.7 (95% CI 6.7 to 8.6) and 8.6 (95% CI 7.5 to 9.7) ml  kg(-1), respectively (P tidal volume of 4 ml kg during OLV was associated with less lung water content than with larger tidal volumes of 6 to 8 ml kg(-1), although no patient developed acute lung injury. Further studies are required to address the usefulness of EVLWI as a marker for the development of postoperative acute lung injury after the use of a low tidal volume during OLV in patients undergoing pulmonary resection.

    The feasibility of extending the VATS approach to locally advanced NSCLC has been described with good clinical outcome. These complex resections are still technically challenging and patient safety must remain the highest priority. In this article, we describe our routine VATS approach for left upper lobectomy in proximal, locally advanced lesions. Both surgical and anaesthesiology teams are trained during simulation sessions to respond rapidly in case of urgent thoracotomy. Encircling arterial and venous vessels allow control of inadvertent bleeding during difficult dissection. Also, whenever needed the double vessel control technique is a time saver waiting for conversion to thoracotomy.

    Current video-assisted thoracoscopic surgery training models rely on animals or mannequins to teach procedural skills. These approaches lack inherent teaching/testing capability and are limited by cost, anatomic variations, and single use. In response, we hypothesized that video-assisted thoracoscopic surgery right upper lobe resection could be simulated in a virtual reality environment with commercial software. An anatomy explorer (Maya [Autodesk Inc, San Rafael, Calif] models of the chest and hilar structures) and simulation engine were adapted. Design goals included freedom of port placement, incorporation of well-known anatomic variants, teaching and testing modes, haptic feedback for the dissection, ability to perform the anatomic divisions, and a portable platform. Preexisting commercial models did not provide sufficient surgical detail, and extensive modeling modifications were required. Video-assisted thoracoscopic surgery right upper lobe resection simulation is initiated with a random vein and artery variation. The trainee proceeds in a teaching or testing mode. A knowledge database currently includes 13 anatomic identifications and 20 high-yield lung cancer learning points. The "patient" is presented in the left lateral decubitus position. After initial camera port placement, the endoscopic view is displayed and the thoracoscope is manipulated via the haptic device. The thoracoscope port can be relocated; additional ports are placed using an external "operating room" view. Unrestricted endoscopic exploration of the thorax is allowed. An endo-dissector tool allows for hilar dissection, and a virtual stapling device divides structures. The trainee's performance is reported. A virtual reality cognitive task simulation can overcome the deficiencies of existing training models. Performance scoring is being validated as we assess this simulator for cognitive and technical surgical education. Copyright © 2011. Published by Mosby, Inc.

    Lung herniation is a rare condition defined as a protrusion of the pleural-covered lung parenchyma through an abnormal defect or weakness in the thoracic wall. Postoperative lung herniation is reported to result from a preceding operation with inadequate closure of the chest wall. A 77-year-old woman was admitted to our hospital for treatment of hemoptysis and nausea. One year previously, she had undergone wedge resection of the right lower lobe (S6) for treatment of primary lung adenocarcinoma. Upon admission, chest radiograph and chest computed tomography showed a right lung herniation through the fifth enlarged intercostal space with right fifth and sixth rib fractures. She underwent surgical closure of the intercostal hernia using synthetic materials with fixation of the fifth and sixth ribs. The patient had developed no recurrence 9 months after surgical repair. In the present case, adequate closure of the right pleural cavity was ensured by fixation of both fifth and sixth ribs during the preceding video-assisted thoracic surgery for the primary lung carcinoma. Our patient may have had some exacerbation factors for lung herniation, increased intrathoracic pressure, attenuation of chest wall by prolonged coughing and rib fracture, and high abdominal pressure due to her hunched-over posture. It is important to know some exacerbation factors for postoperative intercostal lung herniation. Addition of monofirament-suture fixation of the ribs to patch repair is very effective for lung herniation repair in patients with concurrent lung herniation and rib fractures.

    The aim of this retrospective study was to evaluate the practice and the feasibility of Osirix, a free and open-source medical imaging software, in performing accurate video-assisted thoracoscopic lobectomy and segmentectomy. From July 2014 to April 2016, 63 patients received anatomical video-assisted thoracoscopic surgery (VATS), either lobectomy or segmentectomy, in our department. Three-dimensional (3D) reconstruction images of 61 (96.8%) patients were preoperatively obtained with contrast-enhanced computed tomography (CT). Preoperative resection simulations were accomplished with patient-individual reconstructed 3D images. For lobectomy, pulmonary lobar veins, arteries and bronchi were identified meticulously by carefully reviewing the 3D images on the display. For segmentectomy, the intrasegmental veins in the affected segment for division and the intersegmental veins to be preserved were identified on the 3D images. Patient preoperative characteristics, surgical outcomes and postoperative data were reviewed from a prospective database. The study cohort of 63 patients included 33 (52.4%) men and 30 (47.6%) women, of whom 46 (73.0%) underwent VATS lobectomy and 17 (27.0%) underwent VATS segmentectomy. There was 1 conversion from VATS lobectomy to open thoracotomy because of fibrocalcified lymph nodes. A VATS lobectomy was performed in 1 case after completing the segmentectomy because invasive adenocarcinoma was detected by intraoperative frozen-section analysis. There were no 30-day or 90-day operative mortalities CONCLUSIONS: The free, simple, and user-friendly software program Osirix can provide a 3D anatomic structure of pulmonary vessels and a clear vision into the space between the lesion and adjacent tissues, which allows surgeons to make preoperative simulations and improve the accuracy and safety of actual surgery.

    Full Text Available Erica Schipper,1 Camran Nezhat21Center for Minimally Invasive and Robotic Surgery, Palo Alto, CA; 2Obstetrics/Gynecology and Surgery, Stanford University Medical Center, Palo Alto, CA, USAAbstract: Endometriosis is a highly enigmatic disease with multiple presentations ranging from infertility to severe pain, often causing significant morbidity. Video-assisted laparoscopy (VALS has now replaced laparotomy as the gold standard for the diagnosis and management of endometriosis. While imaging has a role in the evaluation of some patients, histologic examination is needed for a definitive diagnosis. Laboratory evaluation currently has a minor role in the diagnosis of endometriosis, although studies are underway investigating serum markers, genetic studies, and endometrial sampling. A high index of suspicion is essential to accurately diagnose this complex condition, and a multidisciplinary approach is often indicated. The following review discusses laparoscopic diagnosis of endometriosis from the pre-operative evaluation of patients suspected of having endometriosis to surgical technique for safe and adequate laparoscopic diagnosis of the condition and postsurgical care.Keywords: endometriosis, video-assisted, laparoscopy, diagnosis

    To compare the postoperative recovery of patients with superior sulcus tumors (Pancoast tumors) following conventional open surgery vs. a hybrid video-assisted and limited open approach (VALO). The subjects of this retrospective study were 20 patients we operated on to resect a Pancoast tumor. All patients received induction chemo-radiation followed by surgery, performed via either a conventional thoracotomy approach (n = 10) or the hybrid VALO approach (n = 10). In the hybrid VALO group, lobectomy and internal chest wall preparation were performed using a video technique, with rib resection and specimen removal through a limited incision. There was no mortality in either group. Two patients from the thoracotomy group required mechanical ventilation, but there was no major morbidity in the hybrid VALO group. The operative times were similar for the two procedures. The average length of hospital stay was shorter and the average pain scores were significantly lower in the hybrid VALO group. The incidence of chronic pain was 10 % in the hybrid VALO group vs. 50 % in the thoracotomy group. Hybrid VALO resection of Pancoast tumors is feasible and safe, resulting in faster patient recovery and a significantly lower incidence of severe chronic pain than open thoracotomy. We conclude that centers experienced with video-assisted lobectomy should consider hybrid VALO surgery as the procedure of choice for Pancoast tumors.

    Plication of a nonfunctional hemidiaphragm usually restores altered ventilatory mechanics. This study compared two techniques in performing diaphragmatic plication: video-assisted thoracoscopy (group A) and thoracotomy (group B). Twenty dogs with induced paralysis of the right hemidiaphragm were randomly assigned to one of the two groups. Evaluations were performed before and after plication of the respiratory frequency (f) and lung area (LA) of the affected side. Operative time, time to resumption of walking, ingestion of fluids and solid food, pain intensity, and postoperative complications were measured. Group A had less pain after the surgery (P fluid ingestion (P < 0.05), and earlier resumption of walking (P < 0.019). Four weeks after the procedure, LA was similar in both groups, while a significant decrease in f was recorded in group A (P < 0.02). The remaining evaluated variables showed no differences. Both approaches were effective. Pain recorded in the postoperative period was less and recovery was faster in group A. Complications and surgical times were similar. The video-assisted thoracoscopy is a safe and efficient option for performing diaphragmatic plication in dogs.

    Full Text Available The advantages of video assisted thoracoscopic surgery (VATS in children have led to its increased usage over the years. VATS, however, requires an efficient technique for one lung ventilation. Today, there is an increasing interest in developing the technique for lung isolation to meet the anatomic and physiologic variations in infants and children. This article aims to provide an updated and comprehensive review on one-lung ventilation strategies for infants and children undergoing VATS. Search of terms such as ′One lung ventilation for infants and children′, ′Video assisted thoracoscopic surgery for infants and children′, and ′Physiologic changes during one lung ventilation for infants and children′ were used. The search mechanics and engines for this review included the following: Kandang Kerbau Hospital (KKH eLibrary, PubMed, Ovid Medline, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews. During the search the author focused on significant current and pilot randomized control trials, case reports, review articles, and editorials. Critical decision making on what device to use based on the age, weight, and pathology of the patient; and how to use it for lung isolation are discussed in this article. Furthermore, additional information regarding the advantages, limitations, techniques of insertion and maintenance of each device for one lung ventilation in infants and children were the highlights in this article.

    The role of surgery in malignant pleural mesothelioma (MPM) remains debatable; nonetheless the relative advantages of different surgical approaches are frequently reassessed and reconsidered. While extensive operations and longer recovery periods can be justified for a group of carefully selected patients, many will present at an advanced stage of their disease or with associated co-morbidities which will exclude them from selection criteria for radical treatment. For these patients, minimally invasive video-assisted procedures may be considered, for purposes of cytoreduction and/or symptomatic relief. Even though there is currently not enough clinical evidence to suggest an improvement in overall survival with limited debulking procedures, it has been suggested that they can improve quality of life over drainage and pleurodesis alone. We consider video-assisted PlasmaJet ablation to potentially have a role in mesothelioma surgery, as it may be used for effective cytoreduction while minimising the risk for complications often associated with extensive pleurectomy procedures, and we report on the use of the PlasmaJet Surgical System in our centre for surgical management of a patient with MPM. After demonstrating safety and absence of major adverse events with this approach, we feel justified in offering the procedure to more of our patients as we aim to collect additional data.

    Measuring patient-reported outcomes (PROs) has become increasingly important for assessing quality of care and guiding patient management. However, PROs have yet to be integrated with traditional clinical outcomes (such as length of hospital stay), to evaluate perioperative care. This study aimed to use longitudinal PRO assessments to define the postoperative symptom recovery trajectory in patients undergoing thoracic surgery for lung cancer. Newly diagnosed patients (N = 60) with stage I or II non-small cell lung cancer who underwent either standard open thoracotomy or video-assisted thoracoscopic surgery lobectomy reported multiple symptoms from before surgery to 3 months after surgery, using the MD Anderson Symptom Inventory. We conducted Kaplan-Meier analyses to determine when symptoms returned to presurgical levels and to mild-severity levels during recovery. The most-severe postoperative symptoms were fatigue, pain, shortness of breath, disturbed sleep, and drowsiness. The median time to return to mild symptom severity for these 5 symptoms was shorter than the time to return to baseline severity, with fatigue taking longer. Recovery from pain occurred more quickly for patients who underwent lobectomy versus thoracotomy (8 vs 18 days, respectively; P = .022). Patients who had poor preoperative performance status or comorbidities reported higher postoperative pain (all P < .05). Assessing symptoms from the patient's perspective throughout the postoperative recovery period is an effective strategy for evaluating perioperative care. This study demonstrates that the MD Anderson Symptom Inventory is a sensitive tool for detecting symptomatic recovery, with an expected relationship among surgery type, preoperative performance status, and comorbid conditions.

    To describe our initial experience with CT-guided percutaneous barium marking for the localization of small pulmonary nodules prior to video-assisted thoracoscopic surgery (VATS). From October 2010 to April 2011, 10 consecutive patients (4 men and 6 women; mean age, 60 years) underwent CT-guided percutaneous barium marking for the localization of 10 small pulmonary nodules (mean size, 7.6 mm; range, 3-14 mm): 6 pure ground-glass nodules, 3 part-solid nodules, and 1 solid nodule. A 140% barium sulfate suspension (mean amount, 0.2 mL; range, 0.15-0.25 mL) was injected around the nodules with a 21-gauge needle. The technical details, surgical findings and pathologic features associated with barium localizations were evaluated. All nodules were marked within 3 mm (mean distance, 1.1 mm; range, 0-3 mm) from the barium ball (mean diameter, 9.6 mm; range, 8-16 mm) formed by the injected barium suspension. Pneumothorax occurred in two cases, for which one needed aspiration. However, there were no other complications. All barium balls were palpable during VATS and visible on intraoperative fluoroscopy, and were completely resected. Both the whitish barium balls and target nodules were identifiable in the frozen specimens. Pathology revealed one invasive adenocarcinoma, five adenocarcinoma-in-situ, two atypical adenomatous hyperplasias, and two benign lesions. In all cases, there were acute inflammations around the barium balls which did not hamper the histological diagnosis of the nodules. CT-guided percutaneous barium marking can be an effective, convenient and safe pre-operative localization procedure prior to VATS, enabling accurate resection and diagnosis of small or faint pulmonary nodules.

    Although video-assisted thoracoscopic surgery (VATS) for thymic disorders has been introduced, its oncological outcome and benefits over others open approaches remains unclear. Single-port VATS thymectomy using a flexible port and CO 2 has been described. However, VATS thymectomy is possible by a single incision of 3 cm without CO 2 insufflation or special port device avoiding objections related to CO 2 insufflation and allowing instruments to move more freely making procedure easier and cheaper. Our institutional experience in open and CO 2 -less VATS single-port thymectomy was retrospectively reviewed to evaluate compared to sternotomy, the clinical and oncological outcomes with this novel approach. A retrospective review consisting of 84 patients who underwent thymectomy because different thymic disorders especially thymoma was performed. Eighteen patients underwent CO 2 -less VATS single port thymectomy, while 66 underwent thymectomy through open sternotomy. Many clinical factors associated with the surgical and clinical outcomes, including tumor recurrence and clinical remission, were recorded. Non major postoperative complications were observed in any group. The median operative time and postoperative hospital stay of CO 2 -less VATS single port thymectomy were 95 min and 1 day, respectively and 120 min and 7 days for open sternotomy. The thymoma was the most common thymic disorder with 7 patients (38%) in VATS group and 28 patients (42.4%) for the open approach. The median lesion size was 2.6 cm in the VATS group and 3.2 cm in the open approach. No thymoma recurrence in patients undergoing VATS was observed during the follow-up time, while in the open surgery group 14.28% recurrence was observed, distributed as follows: loco-regional 75% and 25% at distance; free disease period of these patients was 8.3 months. Thymectomy associated with myasthenia gravis (MG) was observed in 6 (33%) patients in the VATS group and 32 (48%) patients for sternotomy; our

    To describe video-assisted microwave ablation (VAMA) for the treatment of a metastatic lung lesion secondary to right forelimb osteosarcoma in a dog. Case report. A 10-year-old female spayed mixed breed dog with a metastatic lung lesion secondary to appendicular osteosarcoma. An osteosarcoma of the right distal scapula and proximal humerus that was suspected to be a radiation-induced osteosarcoma was treated with limb amputation and carboplatin chemotherapy. The patient developed pulmonary metastatic lesions and hypertrophic osteopathy (HO). VAMA of a metastatic lesion in the right caudal lung lobe was performed 227 days after amputation. The procedure was performed without complication. Follow-up information with the referring veterinarian 40 days after VAMA indicated that the patient was stable and that the clinical signs of HO had resolved. Thoracic radiographs taken by the referring veterinarian (RDVM) at monthly intervals showed that the previously treated metastatic lesion was stable. At 134 days from VAMA, the patient presented to the RDVM for lethargy and dyspnea and was transferred to an emergency clinic. The patient arrested and died 136 days from the VAMA procedure while hospitalized. A postmortem was not performed. VAMA for pulmonary metastatic lesions is technically feasible and allows for the treatment of symptoms associated with HO and minimally invasive management of pulmonary metastases in the case reported. © 2017 The American College of Veterinary Surgeons.

    Video-assisted thoracoscopic surgery (VATS) surgery has changed the way lobectomy procedure was performed over the past few decades. However, some difficulties impede the accomplishment of VATS lobectomy, which of them, benign lymphadenopathy may pose a threat to safety of surgery. We reported a case with enlarged hilar and interlobar lymph nodes. The video showed the instrumentation and techniques that we had adopted to deal with the complicated dilemma during the operation. Critical experience was also suggested in some hypothetical scenarios. AS techniques were further refined, successful VATS segmentectomy or lobectomy with challenging hilar or interlobar lymphadenopathy could be performed without uncontrolled bleeding or unexpected conversion. A VATS approach is acceptable in the management of benign hilar or interlobar lymphadenopathy. However, facile technique is necessary to deal with intraoperative dilemma. To those who are not sure about the practicability of the VATS procedure, planned conversion is still an effective method to ensure safety of the operation.

    Endobronchial lipomas are rare benign tumors whose symptoms are usually confused with recurrent infections or even asthma diagnosis, and mostly caused by endobronquial obstructive component which also conditions severity. We report a case of a 60-year-old man with a right-lower lobe upper-segment endobronchial myxoid tumor with uncertain diagnosis. We performed a single incision video-assisted anatomical segmentectomy and wedge bronchoplasty with handsewn closure to achieve complete resection and definitive diagnosis. During the postoperative air leak was not observed and there was no complication, with low pain scores and complete recovery. Final pathological exam showed endobronchial lipoma. Single-incision (SI) anatomical segmentectomies are lung-sparing resections for benign or low-grade malignancies with diagnostic and therapeutic value, and the need for a wedge bronchoplasty is not a necessary indication for conversion to multiport or open thoracotomy.

    Full Text Available Esophageal leiomyoma is a relatively rare tumor of esophagus but it is the most common benign neoplasm of the esophagus. Small esophageal leiomyoma can be observed but larger ones and those producing symptoms should be excised. As observed for other esophageal tumors, dysphagia is its main symptom. Traditionally, open thoracotomy and enucleation are its main treatment but in the last few years video assisted thoracoscopic surgical (VATS enucleation is gaining recognition with proven advantages of minimally invasive surgery. Herein we present our experience with patient presenting with cough rather than dysphagia as a main symptom, who was diagnosed to be having giant esophageal leiomyoma. VATS guided enucleation was accomplished successfully. Size of lesion was 16×4×3 cm. Postoperative recovery was uneventful and patient is not having any signs of recurrence, after three years during follow-up period.

    Minimally invasive video-assisted epicardial beating heart ablation for lone atrial fibrillation claims to be safe and effective. We, however, report on three patients with an atrioesophageal fistula after this procedure. The exact pathogenesis of this complication is unknown. All patients presented around 6 weeks after surgery with either fever or neurological deficits. Diagnosis can be made by computed tomography scan. We advocate an aggressive surgical approach with closure of the atrial defect on cardiopulmonary bypass and closure and reinforcement of the esophagus with an intercostal muscle flap in a single-stage surgery. Some caution as to the low-risk character of this procedure seems to be realistic. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Sarcomas in the head and neck are rare, and account for approximately 5-15% of all sarcomas in adults, is less than 1% of all neoplasms of the head and neck. Due to anatomical and physiological features of the structure of the nasopharynx, surgical treatment of tumors of this localization is associated with a number of technical difficulties, the high risk of non-radical removal of the tumor, it was therefore necessary for adequate surgical access. The article describes video-assisted access for removal of tumors of the nasopharynx with good visualization of the tumor process simultaneously after laryngectomy with the formation of pharyngotomy, providing the opportunity to monitor the postoperative area of the nasopharynx and early detection of continued tumor growth in patients with soft tissue sarcoma of the nasopharynx and combined lesions of the larynx.

    2017-08-01

    Background  Our pilot study describes our initial experience to do a laser resection of lung metastases under video-assisted thoracoscopic control via a minithoracotomy. With this approach, if needed, mediastinal lymphadenectomy is also possible. Methods  In this study, 15 patients (11 men and 4 women, mean age: 60 years) with resectable lung metastases of different solid primary tumors (colorectal cancer in seven patients, melanoma in three patients, renal cell carcinoma in two patients, and one each with oropharyngeal cancer, breast cancer, and seminoma) were included. An anterior minithoracotomy incision (approximately 5-7 cm length) was created in the fifth intercostal space and a soft tissue retractor (Alexis Protector; Applied Medical) was positioned. Two additional working ports were inserted. The entire lung was palpated via the minithoracotomy. All detected lung metastases were removed under thoracoscopic control. Nonanatomic resections were performed using a diode-pumped neodymium-doped yttrium aluminium garnet laser (LIMAX120; KLS Martin GmbH & Co KG) with a laser power of 80 W in a noncontact modus. Deeper parenchymal lesions were sutured. Results  A total of 29 lung metastases up to 30 mm in size were resected and all metastases diagnosed on preoperative imaging were detected. All diagnosed lung metastases were completely resected (R0). The median operation time was 102 (range: 85-120) minutes. Median blood loss was 47.6 mL and no postoperative complications occurred. Neither local recurrences nor new lung metastases were observed within 6 months after the procedures. Conclusion  Video-assisted laser resection of lung metastases is safe, effective, and fulfills the requirements of modern lung metastases surgery. Georg Thieme Verlag KG Stuttgart · New York.

    Theoretically, video-assisted mediastinoscopy (VAM) offers improved staging of subcarinal lymph nodes (LNs) compared with standard cervical mediastinoscopy (SCM). Materials and Between 2006 and 2011, 553 patients (SCM, n = 293; VAM, n = 260) with non-small cell lung carcinoma who underwent mediastinoscopy were investigated. Mediastinoscopy was performed only in select patients based on computed tomography (CT) or positron emission tomography CT scans in our center. The mean number of LNs and stations sampled per case was significantly higher with VAM (n = 7.65 ± 1.68 and n = 4.22 ± 0.83) than with SCM (n = 6.91 ± 1.65 and 3.92 ± 86.4; p < 0.001). The percentage of patients sampled in station 7 was significantly higher with VAM (98.8%) than with SCM (93.8%; p = 0.002). Mediastinal LN metastasis was observed in 114 patients by mediastinoscopy. The remaining 439 patients (203 patients in VAM and 236 in SCM) underwent thoracotomy and systematic mediastinal lymphadenectomy (SML). SML showed mediastinal nodal disease in 23 patients (false-negative [FN] rate, 5.2%). The FN rate was higher with SCM (n = 14, 5.9%) than with VAM (n = 9, 4.4%), although this difference was not statistically significant (p = 0.490). Station 7 was the most predominant station for FN results (n = 15). The FN rate of station 7 was found to be higher with SCM (n = 9, 3.8%) than with the VAM group (n = 6, 2.9%; p = 0.623). FN were more common in mediastinoscopy of subcarinal LNs. VAM allows higher rates of sampling of mediastinal LN stations and station 7, although it did not improve staging of subcarinal LNs.

    Early pain and persistent parietal disorders remains a major unresolved problem in thoracic surgery. Thoracotomy and the use of multiple ports in most Video Assisted Thoracic Surgery (VATS) procedures are the major cause of this persistent pain. For the last decade, a few publications describing the use of either single incision VATS and cervical thoracic approaches have been reported without significant results in comparison with current used techniques. Intercostals compression during surgery and early after by intercostals chest tube placement, are probably the major cause of postoperative pain. Flexible endoscope is currently used in several surgeries and will take more and more importance in our daily use in thoracic surgery. Instrument flexibility allows its use through minimally invasive approaches and offers a very interesting intra-thoracic navigation. We describe here the first use in France of a flexible endoscope in thoracic surgery through a single cervical incision to perform simultaneous exploration and biopsies of the mediastinum and right pleura using the original approach of Cervical Incision Thoracic Endoscopic Surgery (CITES).

    Full Text Available Online video lectures have been considered an instructional media for various pedagogic approaches, such as the flipped classroom and open online courses. In comparison to other instructional media, online video affords the opportunity for recording student clickstream patterns within a video lecture. Video analytics within lecture videos may provide insights into student learning performance and inform the improvement of video-assisted teaching tactics. Nevertheless, video analytics are not accessible to learning stakeholders, such as researchers and educators, mainly because online video platforms do not broadly share the interactions of the users with their systems. For this purpose, we have designed an open-access video analytics system for use in a video-assisted course. In this paper, we present a longitudinal study, which provides valuable insights through the lens of the collected video analytics. In particular, we found that there is a relationship between video navigation (repeated views and the level of cognition/thinking required for a specific video segment. Our results indicated that learning performance progress was slightly improved and stabilized after the third week of the video-assisted course. We also found that attitudes regarding easiness, usability, usefulness, and acceptance of this type of course remained at the same levels throughout the course. Finally, we triangulate analytics from diverse sources, discuss them, and provide the lessons learned for further development and refinement of video-assisted courses and practices.

    Parapneumonic empyema patients with coronary artery disease and reduced left ventricular ejection fraction are risky to receive surgical decortication under general anesthesia. Non-intubated video-assisted thoracoscopy surgery is successfully performed to avoid complications of general anesthesia. We performed single-port non-intubated video-assisted flexible thoracoscopy surgery in an endoscopic center. In this study, the possible role of our modified surgery to treat fibrinopurulent stage of parapneumonic empyema with high operative risks is investigated. We retrospectively reviewed fibrinopurulent stage of parapneumonic empyema patients between July 2011 and June 2014. Thirty-three patients with coronary artery disease and reduced left ventricular ejection fraction were included in this study. One group received tube thoracostomy, and the other group received single-port non-intubated video-assisted flexible thoracoscopy surgery decortication. Patient demographics, characteristics, laboratory findings, etiology, and treatment outcomes were compared. Mean age of 33 patients (24 males, 9 females) was 76.2 ± 9.7 years. Twelve patients received single-port non-intubated video-assisted flexible thoracoscopy surgery decortication, and 21 patients received tube thoracostomy. Visual analog scale scores on postoperative first hour and first day were not significantly different in two groups (p value = 0.5505 and 0.2750, respectively). Chest tube drainage days, postoperative fever subsided days, postoperative hospital days, and total length of stay were significantly short in single-port non-intubated video-assisted flexible thoracoscopy surgery decortication (p value = 0.0027, 0.0001, 0.0009, and 0.0065, respectively). Morbidities were low, and mortality was significantly low (p value = 0.0319) in single-port non-intubated video-assisted flexible thoracoscopy surgery decortication.

    Management of chest trauma is integral to patient outcomes owing to the vital structures held within the thoracic cavity. Understanding traumatic chest injuries and appropriate management plays a pivotal role in the overall well-being of both blunt and penetrating trauma patients. Whether the injury includes rib fractures, associated pulmonary injuries, or tracheobronchial tree injuries, every facet of management may impact the short- and long-term outcomes, including mortality.

    Objectives Theoretically, video-assisted mediastinoscopy (VM) should provide a decrease in the incidence of hoarseness in comparison with conventional mediastinoscopy (CM). Methods An investigation of 448 patients with the NSCLC who underwent mediastinoscopy (n = 261 VM, n = 187 CM) between 2006 and 2010. Results With VM, the mean number of sampled LNs and of stations per case were both significantly higher (n = 7.91 ± 1.97 and n = 4.29 ± 0.81) than they were for CM (n = 6.65 ± 1.79 and n = 4.14 ± 0.84) (p < 0.001 and p = 0.06). Hoarseness was reported in 24 patients (5.4%) with VM procedures resulting in a higher incidence of hoarseness than did CM procedures (6.9% and 3.2%) (p = 0.08). The incidence of hoarseness was observed to be more frequent in patients with left-lung carcinoma who had undergone a mediastinoscopy (p = 0.03). Hoarseness developed in 6% of the patients sampled at station 4L, whereas this ratio was 0% in patients who were not sampled at 4L (p = 0.07). A multivariate analysis showed that the presence of a tumor in the left lung is the only independent risk factor indicating hoarseness (p = 0.09). The sensitivity, NPV, and accuracy of VM were calculated as to be 0.87, 0.95, and 0.96, respectively. The same staging values for CM were 0.83, 0.94, and 0.95, respectively. Conclusion VM, the presence of a tumor in the left-lung, and 4L sampling via mediastinoscopy are risk factors for subsequent hoarseness. Probably due to a wider area of dissection, VM can lead to more frequent hoarseness.

    Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block. There were no intraoperative neither postoperative complications, the chest tube was removed at 24 hours and the patient discharged at 5 th postoperative day with low pain on the visual analogue scale (VAS). Final pathologic exam reported a benign sclerosant pneumocytoma with free margins. The patient has recovered her normal activities at 3 months completely with radiological normal controls at 1 and 3 months.

    Full Text Available Knowledge about the impact of Low-Molecular-Weight Heparin (LMWH on the coagulation system in patients undergoing minimal invasive lung cancer surgery is sparse. The aim of this study was to assess the effect of LMWH on the coagulation system in patients undergoing Video-Assisted Thoracoscopic Surgery (VATS lobectomy for primary lung cancer.Sixty-three patients diagnosed with primary lung cancer undergoing VATS lobectomy were randomized to either subcutaneous injection with dalteparin (Fragmin® 5000 IE once daily or no intervention. Coagulation was assessed pre-, peri-, and the first two days postoperatively by standard coagulation blood test, thromboelastometry (ROTEM® and thrombin generation.Patients undergoing potential curative surgery for lung cancer were not hypercoagulable preoperatively. There was no statistically significant difference in the majority of the assessed coagulation parameters after LMWH, except that the no intervention group had a higher peak thrombin and a shorter INTEM clotting time on the first postoperative day and a lower fibrinogen level on the second postoperative day. A lower level of fibrin d-dimer in the LMWH group was found on the 1. and 2.postoperative day, although not statistical significant. No differences were found between the two groups in the amount of bleeding or number of thromboembolic events.Use of LMWH administered once daily as thromboprophylaxis did not alter the coagulation profile per se. As the present study primarily evaluated biochemical endpoints, further studies using clinical endpoints are needed in regards of an optimized thromboprophylaxis approach.

    Rogério Luizari Guedes

    Full Text Available ABSTRACT: This study evaluated the use of bipolar electrosurgery and laparoscopic clipping, and their effects on blood loss and the inflammatory response, during a two portal video-assisted ovariohysterectomy technique (two groups with 10 animals each. Surgical time and blood loss volume were significantly lower in the electrosurgery group. There were no significant changes in haematocrit between groups; however, haematocrit did differ between evaluated times, and decreased 10% from the initial measurement to four hours after the procedure. The inflammatory response was significantly higher throughout the post-surgical period, but without any different clinical signs between the two groups. Both techniques had good application for the two portal video-assisted procedure; however, the bipolar electrosurgery allowed for shorter surgical times, reduced blood loss and a minimal learning curve for the surgeon.

    Art Ambrosio MD

    2017-05-01

    Full Text Available Objective Difficult airway management is a key skill required by all pediatric physicians, yet training on multiple modalities is lacking. The objective of this study was to compare the rate of, and time to, successful advanced infant airway placement with direct laryngoscopy, video-assisted laryngoscopy, and laryngeal mask airway (LMA in a difficult airway simulator. This study is the first to compare the success with 3 methods for difficult airway management among pediatric trainees. Study Design Randomized crossover pilot study. Setting Tertiary academic medical center. Methods Twenty-two pediatric residents, interns, and medical students were tested. Participants were provided 1 training session by faculty using a normal infant manikin. Subjects then performed all 3 of the aforementioned advanced airway modalities in a randomized order on a difficult airway model of a Robin sequence. Success was defined as confirmed endotracheal intubation or correct LMA placement by the testing instructor in ≤120 seconds. Results Direct laryngoscopy demonstrated a significantly higher placement success rate (77.3% than video-assisted laryngoscopy (36.4%, P = .0117 and LMA (31.8%, P = .0039. Video-assisted laryngoscopy required a significantly longer amount of time during successful intubations (84.8 seconds; 95% CI, 59.4-110.1 versus direct laryngoscopy (44.9 seconds; 95% CI, 33.8-55.9 and LMA placement (36.6 seconds; 95% CI, 24.7-48.4. Conclusions Pediatric trainees demonstrated significantly higher success using direct laryngoscopy in a difficult airway simulator model. However, given the potential lifesaving implications of advanced airway adjuncts, including video-assisted laryngoscopy and LMA placement, more extensive training on adjunctive airway management techniques may be useful for trainees.

  10. Robotic thoracic surgery: The state of the art

    2015-01-01

    Minimally invasive thoracic surgery has come a long way. It has rapidly progressed to complex procedures such as lobectomy, pneumonectomy, esophagectomy, and resection of mediastinal tumors. Video-assisted thoracic surgery (VATS) offered perceptible benefits over thoracotomy in terms of less postoperative pain and narcotic utilization, shorter ICU and hospital stay, decreased incidence of postoperative complications combined with quicker return to work, and better cosmesis. However, despite its obvious advantages, the General Thoracic Surgical Community has been relatively slow in adapting VATS more widely. The introduction of da Vinci surgical system has helped overcome certain inherent limitations of VATS such as two-dimensional (2D) vision and counter intuitive movement using long rigid instruments allowing thoracic surgeons to perform a plethora of minimally invasive thoracic procedures more efficiently. Although the cumulative experience worldwide is still limited and evolving, Robotic Thoracic Surgery is an evolution over VATS. There is however a lot of concern among established high-volume VATS centers regarding the superiority of the robotic technique. We have over 7 years experience and believe that any new technology designed to make minimal invasive surgery easier and more comfortable for the surgeon is most likely to have better and safer outcomes in the long run. Our only concern is its cost effectiveness and we believe that if the cost factor is removed more and more surgeons will use the technology and it will increase the spectrum and the reach of minimally invasive thoracic surgery. This article reviews worldwide experience with robotic thoracic surgery and addresses the potential benefits and limitations of using the robotic platform for the performance of thoracic surgical procedures.

    Feedback can significantly improve future performance. Reviewing one's performance by video is discussed as useful adjunct to debriefing, particularly for non-technical skills. Communicative competencies are an essential part of daily clinical practice; thus should be taught and assessed during undergraduate training. The aim of this study was to compare the educational value of video-assisted feedback versus oral feedback in communicative competencies in the surgical context. Fourth-year medical students completed a 210-min training unit of 'taking patient's history and obtaining informed consents prior to surgery' using role plays. Oral feedback was received directly thereafter using agenda-led, outcome-based guidelines (ALOBA). In the study group, the role plays were video-taped and reviewed thereafter. Afterwards, students completed two OSCE stations, where they were assessed regarding their communicative competencies and the content of the clinical scenario. One-hundred students (49 receiving video-assisted feedback, 51 oral) participated in the study. Those receiving video-assisted feedback performed significantly better in overall score in both OSCE stations (p feedback offered a significant educational benefit over oral feedback alone during a simulated patient encounter in a surgical context.

    Background Minimally invasive surgery has been recently recommended for treatment of early-stage non-small cell lung cancer. Despite the recent increase of robotic surgery, the place and potential advantages of the robot in thoracic surgery has not been well defined until now. Methods We reviewed our prospective database for retrospective comparison of our first 28 video-assisted thoracoscopic surgery lobectomies (V group) and our first 28 robotic lobectomies (R group). Results No significant difference was shown in median operative time between the two groups (185 vs. 190 minutes, p = 0.56). Median preincision time was significantly longer in the R group (80 vs. 60 minutes, P < 0.0001). The rate of emergency conversion for uncontrolled bleeding was lower in the R group (one vs. four). Median length of stay was comparable (6 days in the R group vs. 7 days in the V group, p = 0.4) with no significant difference in the rate of postoperative complications (eight Grade I in both groups, four Grade III or IV in the V group vs. six in the R group, according to the Clavien-Dindo classification, p = 0.93). No postoperative cardiac morbidity was observed in the R group. Median drainage time was similar (5 days, p = 0.78), with a rate of prolonged air leak slightly higher in the R group (25 vs. 17.8%, p = 0.74). Conclusion Perioperative outcomes are similar even in the learning period but robotic approach seems to offer more operative safety with fewer conversions for uncontrolled bleeding.

    To determine the predictive value of identifying calcified lymph nodes (LNs) for the perioperative outcomes of video-assisted thoracoscopic surgery (VATS). Fifty-six consecutive patients who underwent VATS lobectomy for lung cancer were included. We evaluated the number and location of calcified LNs on computed tomography (CT). We investigated clinical parameters, including percentage forced expiratory volume in 1 s (FEV{sub 1}%), surgery duration, chest tube indwelling duration, and length of hospital stay. We performed linear regression analysis and multiple comparisons of perioperative outcomes. Mean number of calcified LNs per patient was 0.9 (range, 0-6), mostly located in the hilar-interlobar zone (43.8 %). For surgery duration (mean, 5.0 h), FEV{sub 1}% and emphysema severity were independent predictors (P = 0.010 and 0.003, respectively). The number of calcified LNs was an independent predictor for chest tube indwelling duration (P = 0.030) and length of hospital stay (P = 0.046). Mean duration of chest tube indwelling and hospital stay was 8.8 days and 12.7 days in no calcified LN group; 9.2 and 13.2 in 1 calcified LN group; 12.8 and 19.7 in {>=}2 calcified LNs group, respectively. The presence of calcified LNs on CT can help predict more complicated perioperative course following VATS lobectomy. (orig.)

    Secondary spontaneous pneumothorax is difficult to treat and has been thought to have high morbidity and mortality rate due to the underlying diseases and presence of comorbidities in the patients. However, early surgical intervention will be beneficial if it is tolerable by the patient. In the surgical approach for treating pneumothorax, video-assisted thoracoscopic surgery (VATS) may reduce the postoperative drainage period and hospital stay compared with open thoracotomy. A retrospective review of the clinical data of 40 patients with secondary spontaneous pneumothorax who underwent open thoracotomy (n = 20) or two-port VATS (n = 20) between January 2008 and December 2012 was performed. Postoperative drainage period of open thoracotomy group and two-port VATS group was 9.85 ± 5.28 and 6.75 ± 2.45, respectively, with a significant inter-group difference. Postoperative hospital stay was 11.8 ± 5.12 in the open thoracotomy group and 8.25 ± 2.88 in the two-port VATS group, with a significant inter-group difference. Recurrence rate and postoperative complication rate were not significant between the two groups. In selected patients with secondary spontaneous pneumothorax treated with surgical approach, two-port VATS resulted in shorter postoperative drainage period and hospital stay compared with open thoracotomy.

    Additional use of the video-assisted thoracoscopic surgery (VATS) technique in the Nuss procedure has been globally accepted for the improvement of safety of surgical treatment as well as for decreased frequency of serious intraoperative and postoperative complications. To evaluate VATS in surgical treatment of patients with pectus excavatum by the left-to-right Nuss procedure for prevention of serious intra- and postoperative complications. From 2002 to 2016, 1006 patients with pectus excavatum aged 7 to 62 years (mean: 18.6) underwent the Nuss procedure. There were 796 males and 210 females. The clinical records of all patients were analyzed retrospectively. The follow-up varied from 1 to 172 months (mean: 80.7 ±43). The early 30-day postoperative mortality was zero. Early thoracoscopy-dependent postoperative complications, the majority transient and non-life-threatening, occurred in 35.6% of patients. The most frequent complication was pneumothorax, diagnosed in 24.5% of patients. Two patients required repeat surgery. One patient required VATS pleurectomy due to persistent postoperative air leakage. In another patient left thoracotomy following bleeding from the pleural cavity was performed. The use of VATS in the left-to-right Nuss procedure for pectus excavatum ensures the safety of surgical treatment and minimizes the occurrence of serious intra- and postoperative complications concerning injury of the mediastinum, lung, diaphragm or abdominal cavity.

    Intraoperative neural monitoring (IONM) technology was applied in minimally invasive video-assisted thyroidectomy (MIVAT) to explore its safety and effectiveness. Data were collected retrospectively from October 2009 to August 2011. Inclusion criteria included the following: (1) benign thyroid nodule with maximum diameter less than 4.0 cm by preoperative ultrasound evaluation; (2) no previous thyroid surgeries; (3) no cervical radiation history; (4) normal function of recurrent laryngeal nerve (RLN) examined by preoperative laryngoscopy; (5) patients who did not accept to take a "wait and see" follow-up strategy. Enrolled patients were randomly allocated into NIM group and control group. 46 patients were enrolled in NIM group, and 51 patients were enrolled in control group. All surgeries in NIM group were performed successfully, and majority of tracheal intubations were placed with one attempt. 47 RLNs in NIM group and 60 RLNs in control group were exposed. The time of RLN locating was 6.06 ± 1.48 min in NIM group and 6.92 ± 1.34 min in control group (p = .02). The time of RLN tracing and exposing was 28.96 ± 4.75 min in NIM group and 32.17 ± 5.56 min in control group (p = .02). 1 case of temporary RLN paralysis was observed in both groups, and no permanent RLN paralysis was reported. The application of intermittent IONM in MIVAT is feasible. Intermittent IONM can help reduce the time of RLN locating and the time of RLN tracing and exposing.

    Small pulmonary lesions not previously seen on chest radiographs will likely be detected with increasing frequency because of the spread of CT screening. For the diagnosis and treatment of such lesions, we frequently perform resection by video-assisted thoracoscopic surgery (VATS). We performed fluoroscopy-guided barium marking for localization of small peripheral pulmonary lesions before VATS resection, and examined its reliability, safety, and usefulness. We studied 46 patients with peripheral pulmonary lesions 20 mm or less in diameter who were scheduled to undergo VATS resection. The average diameter of the lesions was 10.2±0.5 mm (mean±standard error), and the average distance from the pleural surface was 10.1±0.8 mm. The optimal site for the catheter tip was decided on chest radiographs using CT scans for reference beforehand, and a catheter was inserted bronchoscopically into the target segment and guided to the presumed lesion. A 50% (weight/volume) barium sulfate suspension was instilled into the bronchus through the catheter, and the site of barium marking was checked by CT scanning. The average instilled volume of barium was 0.36±0.03 ml. On CT scans, barium spots were superimposed on the target lesions in 35 of the 46 patients and were only 15 mm from the lesions in the other patients. Barium was well recognized in all patients at the time of VATS resection, and we could confirm the diagnosis in all patients. A mild cough persisted for about 1 week in 1 patient, but the other patients had no specific complications. Fluoroscopy-guided barium marking is a safe, convenient, and reliable method for localization of small pulmonary lesions before VATS resection. (author)

    The purpose of this study was to compare the findings on high-resolution CT (HRCT) of the chest with those on video-assisted thoracoscopy for the detection of bullae in patients who had undergone an operation for spontaneous pneumothorax, and we also wished to evaluate the relationship between the characteristics of bullae on HRCT and development of spontaneous pneumothorax. Fifty patients with spontaneous pneumothorax who had undergone both HRCT of the chest and video-assisted thoracoscopic surgery were included in the study. Spontaneous pneumothoraces were classified as either primary or secondary pneumothorax, and as initial or recurrent pneumothorax. The HRCT scans were obtained with 1 mm slice thickness and a 5 mm scan interval. Two radiologists retrospectively compared the HRCT findings of the chest with those findings on video-assisted thoracoscopy for the detection of bullae, and they evaluated the value of HRCT for diagnosing bullae. In addition, we assessed the size and number of bullae in these patients, and we also evaluated the relationship between those findings of bullae and the development of spontaneous pneumothorax. Bullae were detected in 40 patients by using video-assisted thoracoscopy, and HRCT showed bullae in 38 of these patients. Bullae were not identified with video-assisted thoracoscopy in the remaining ten patients, and among these ten patients, bullae were not demonstrated by HRCT in eight of them. Therefore, the sensitivity and specificity of HRCT for the detection of bullae were 95% (38/40| and 80% (8/10), respectively. The average size of the bullae of the affected hemithorax and the contralateral un-affected hemithorax was 1.97 cm ± 2.30 and 1.24 cm±1.46, respectively. Pneumothorax was more frequently observed in the hemithorax with larger bullae (p 0.05). The average size of bullae in patients with secondary pneumothorax and those bullae of patients with primary pneumothorax was 4.44 cm±4.06 and 1.42 cm±1.26, respectively. The

    Radioactive marking can be a valuable extension to minimally invasive surgery. The technique has been clinically applied in procedures involving sentinel lymph nodes, parathyroidectomy as well as interventions in thoracic surgery. Improvements in equipment and techniques allow one to improve the limits. Pulmonary nodules are frequently surgically removed for diagnostic or therapeutic reasons; here video-assisted thoracoscopic surgery (VATS) is the preferred technique. VATS might be impossible with nodules that are small or located deep in the lung. In this study, we examined the clinical application and safety of employing the newly developed handheld single photon emission tomography (handheld SPECT) device in combination with CT-guided radioactive marking of pulmonary nodules. In this pilot study, 10 subjects requiring surgical resection of a pulmonary nodule were included. The technique involved CT-guided marking of the target nodule with a 20-G needle, with subsequent injection of 25-30 MBq (effective: 7-14 MBq) Tc-99m MAA (Macro Albumin Aggregate). Quality control was made with conventional SPECT-CT to confirm the correct localization and exclude possible complications related to the puncture procedure. VATS was subsequently carried out using the handheld SPECT to localize the radioactivity intraoperatively and therefore the target nodule. A 3D virtual image was superimposed on the intraoperative visual image for surgical guidance. In 9 of the 10 subjects, the radioactive application was successfully placed directly in or in the immediate vicinity of the target nodule. The average size of the involved nodules was 9 mm (range 4-15). All successfully marked nodules were subsequently completely excised (R0) using VATS. The procedure was well tolerated. An asymptomatic clinically insignificant pneumothorax occurred in 5 subjects. Two subjects were found to have non-significant discrete haemorrhage in the infiltration canal of the needle. In a single subject, the

    Submucosal tunneling endoscopic resection (STER) has been proved to be safe and effective for removal of esophageal leiomyoma originating from the muscularis propria (MP) layer. However, there are still technical challenges for tumors ≥35 mm due to the limited space of the submucosal tunnel. The aim of the study was to estimate the safety and efficacy of STER for large esophageal leiomyoma originating from the MP layer as well as compare its efficacy with video-assisted thoracoscopic surgery (VATS), which is a standard procedure for treating esophageal leiomyoma. We retrospectively collected the clinical data of the patients with esophageal leiomyoma of 35-55 mm who underwent STER or VATS at our hospital between January 2010 and December 2014. Epidemiological data (gender, age), tumor location, tumor size, procedure-related parameters, complications, length of stay and cost were compared between STER and VATS. A total of 31 patients were enrolled, and 18 patients underwent STER and the other 13 received VATS. There was no significant difference between the two groups in gender, age, tumor location, tumor size, complications and rate of en bloc resection (P > 0.05). However, patients in the STER groups had a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost (P leiomyoma of 35-55 mm. However, STER is superior to VATS in a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost.

    Full Text Available Background and objective Video-assisted thoracoscopic surgery (VATS theoretically offers advantages over open thymectomy for clinically early-stage (Masaoka-Koga stage I and II thymic malignancies. However, longterm outcomes have not been well studied. We compared the postoperative outcomes and survival from a cohort study based on the database of the Chinese Alliance for Research in Thymomas (ChART. Methods Between 1994 and 2012, data of 1,117 patients having surgery for clinically early-stage (Masaoka-Koga stage I and II tumors were enrolled for the study. Among them, 241 cases underwent VATS thymectomy (VATS group, while 876 cases underwent open thymectomy (Open group. Univariate analyses were used to compare the clinical character and perioperative outcomes between the two groups. And multivariate analysis was performed to determine the independent predictive factors for long-term survival. Results Compared with the Open group, the VATS group had higher percentage of total thymectomy (80.5% vs 73.9%, P=0.028, resection rate (98.8% vs 88.7%, P<0.001 and less recurrence (2.9% vs 16.0%, P<0.001. Five-year overall survival was 92% after VATS and 92% after open thymectomy, with no significant difference between the two groups (P=0.15. However, 5-year disease free survival were 92% in VATS group and 83% in Open group (P=0.011. Cox proportional hazards model revealed that WHO classification, Masaoka-Koga stage and adjuvant therapy were independent predictive factors for overall survival, while surgical approach had no significant impact on long-term outcome. Conclusion This study suggests that VATS thymectomy is an effective approach for clinically early-stage thymic malignancies. And it may offer better perioperative outcomes, as well as equal oncological survival.

    The 4-stage approach (4-SA) is used as a didactic method for teaching practical skills in international courses on resuscitation and the structured care of trauma patients. The aim of this study was to evaluate objective and subjective learning success of a video-assisted 4-SA in teaching undergraduate medical students. The participants were medical students learning the principles of the acute treatment of trauma patients in their multidiscipline course on emergency and intensive care medicine. The participants were quasi- randomly divided into two groups. The 4-SA was used in both groups. In the control group, all four steps were presented by an instructor. In the study group, the first two steps were presented as a video. At the end of the course a 5-minute objective, structured clinical examination (OSCE) of a simulated trauma patient was conducted. The test results were divided into objective results obtained through a checklist with 9 dichotomous items and the assessment of the global performance rated subjectively by the examiner on a Likert scale from 1 to 6. 313 students were recruited; the results of 256 were suitable for analysis. The OSCE results were excellent in both groups and did not differ significantly (control group: median 9, interquantil range (IQR) 8-9, study group: median 9, IQR 8-9; p = 0.29). The global performance was rated significantly better for the study group (median 1, IQR 1-2 vs. median 2, IQR 1-3; p students in their evaluation after the course, was greater in the study group (85% vs. 80%). It is possible to employ video assistance in the classical 4-SA with comparable objective test results in an OSCE. The global performance was significantly improved with use of video assistance.

    New symptom onset of respiratory distress without other cause, and new hemi-diaphragmatic elevation on chest radiography postcardiotomy, are usually adequate for the diagnosis of phrenic nerve paresis. The symptom severity varies (asymptomatic state to severe respiratory failure) depending on the degree of the lesion (paresis vs. paralysis), the laterality (unilateral or bilateral), the age, and the co-morbidity (respiratory, cardiac disease, morbid obesity, etc). Surgical treatment (hemi-diaphragmatic plication) is indicated only in the presence of symptoms. The established surgical treatment is plication of the affected hemidiaphragm which is generally considered safe and effective. Several techniques and approaches are employed for diaphragmatic plication (thoracotomy, video-assisted thoracoscopic surgery, video-assisted mini-thoracotomy, laparoscopic surgery). The timing of surgery depends on the severity and the progression of symptoms. In infants and young children with postcardiotomy phrenic nerve paresis the clinical status is usually severe (failure to wean from mechanical ventilation), and early plication is indicated. Adults with postcardiotomy phrenic nerve paresis usually suffer from chronic dyspnoea, and, in the absence of respiratory distress, conservative treatment is recommended for 6 months -2 years, since improvement is often observed. Nevertheless, earlier surgical treatment may be indicated in non-resolving respiratory failure. We present early (25th day postcardiotomy) right hemi-diaphragm plication, through a video assisted mini-thoracotomy in a high risk patient with postcardiotomy phrenic nerve paresis and respiratory distress. Early surgery with minimal surgical trauma, short operative time, minimal blood loss and postoperative pain, led to fast rehabilitation and avoidance of prolonged hospitalization complications. The relevant literature is discussed. PMID:23304442

    Thoracoscopic surgery for atrial fibrillation (AF) is an attractive and emerging treatment modality. However, when a bleeding occurs access for hemostasis is limited. Therefore, a sternotomy might be necessary to stop the bleeding and continue the operation. We report 2 patients with a periprocedural bleeding in whom sternotomy could be prevented by tamponading the bleeding, interrupting the operation and resuming 3 weeks later. Our cases show that sternotomies can be prevented and that there is a second chance for thoracoscopic surgery for AF. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Double-lumen endotracheal tubes (DL-ETT) and bronchial blockers (BB) have both been used for lung isolation in video-assisted thoracic surgery (VATS). Though not well studied, it is widely thought that a DL-ETT provides faster and better quality lung collapse. The aim of this study was to compare a BB technique vs a left-sided DL-ETT strategy with regard to the time and quality of lung collapse during one-lung ventilation (OLV) for elective VATS. Forty patients requiring OLV for VATS were randomized to receive a BB (n = 20) or a left-sided DL-ETT (n = 20). The primary endpoint was the time from pleural opening (performed by the surgeon) until complete lung collapse. The time was evaluated offline by reviewing video recorded during the VATS. The quality of lung deflation was also graded offline using a visual scale (1 = no lung collapse; 2 = partial lung collapse; and 3 = total lung collapse) and was recorded at several time points after pleural incision. The surgeon also graded the time to complete lung collapse and quality of lung deflation during the procedure. The surgeon's guess as to which device was used for lung isolation was also recorded. Of the 40 patients enrolled in the study, 20 patients in the DL-ETT group and 18 in the BB group were analyzed. There mean (standard deviation) time to complete lung collapse of the operative lung was significantly faster using the BB compared with using the DL-ETT [7.5 (3.8) min vs 36.6 (29.1) min, respectively; mean difference, 29.1 min; 95% confidence interval, 1.8 to 7.2; P < 0.001]. Overall, a higher proportion of patients in the BB group than in the DL-ETT group achieved a quality of lung collapse score of 3 at five minutes (57% vs 6%, respectively; P < 0.004), ten minutes (73% vs 14%, respectively; P = 0.005), and 20 min (100% vs 25%, respectively; P = 0.002) after opening the pleura. The surgeon incorrectly guessed the type of device used in 78% of the BB group and 50% of the DL-ETT group (P = 0.10). The time and

    The aim of this study was to compare the quality of lung deflation of a left-sided double-lumen endotracheal tube (DLT) with a bronchial blocker (BB) for one-lung ventilation in video-assisted thoracic surgery (VATS). A prospective, randomized, clinical study. A university-affiliated teaching hospital. Forty-five adult patients undergoing esophageal tumor surgery using VATS with right lung deflation. Patients were assigned by a computer-generated randomization sequence to either the left-sided DLT or BB group. The correct positioning of the airway device was confirmed using fiberoptic bronchoscopy. The variables assessed included: (1) time required to correctly place the devices and to achieve lung collapse; (2) the number of times the device malpositioned; (3) the quality of lung deflation as rated by the surgeon; (4) blood pressure and heart rate at baseline (T 1 ), immediately before (T 2 ) and after (T 3 ) and 1 minute (T 4 ) after intubation; (5) the number of patients with hypoxemia (SpO 2 one-lung ventilation (OLV) period; and (6) postoperative hoarseness of voice, sore throat, or pulmonary infection. Of the 45 patients approached for the study, 21 patients in the DLT group and 19 patients in the BB group were analyzed. The time required to place the device in the correct position was similar between the 2 groups. The time to achieve right lung collapse in the BB group was significantly longer (mean difference: 3.232, 95% confidence interval [CI]: 1.993-4.471; p = 0.003). The quality of lung collapse, OLV duration, number of patients with device malposition, and hypoxemia in both groups were similar. There were more patients suffering hoarseness (odds ratio [OR]: 4.85, 95% CI: 1.08-21.76; p = 0.034) or sore throat (OR: 4.29, 95% CI: 1.14-16.18; p = 0.030) in the DLT group, while no patients developed postoperative lung infection in either group.

    PurposeThis study was designed to investigate thoracic duct collateral leakage and the supply route of lymphatic fluid by lymphangiography and transcatheter thoracic ductography and to evaluate the results of embolization for thoracic duct collateral leakage performed to cut off this supply route.MethodsData were retrospectively collected from five patients who underwent embolization for thoracic duct collateral leakage in persistent high-output chylothorax after thoracic surgery. Extravasation of lipiodol at the ruptured thoracic duct collaterals was confirmed in all patients on lymphangiography. Transcatheter thoracic ductography was used to identify extravasation of iodinated contrast agent and to identify communication between the thoracic duct and leakage site. Thoracic duct embolization (TDE) was performed using the percutaneous transabdominal approach to cut off the supply route using N-butyl cyanoacrylate (NBCA) mixed with lipiodol (1:5–1:20).ResultsClinical success (drainage volume ≤10 mL/kg/day within 7 days after TDE) was achieved in all patients. The collateral routes developed as consequence of surgical thoracic duct ligation. In three patients, NBCA-Lipiodol reached the leakage site through direct communication between the thoracic duct and the ruptured lymphatic duct. In the other two patients, direct communication and extravasation was not detected on thoracic ductography, and NBCA-Lipiodol did not reach the leakage site. However, NBCA-Lipiodol did reach the cisterna chyli, lumbar trunks, and some collateral routes via the cisterna chyli or lumbar lymphatics. As a result, leakage was stopped.ConclusionsTDE was effective for the management of leakage of the collaterals in high-output chylothorax after thoracic surgery.

    PurposeThis study was designed to investigate thoracic duct collateral leakage and the supply route of lymphatic fluid by lymphangiography and transcatheter thoracic ductography and to evaluate the results of embolization for thoracic duct collateral leakage performed to cut off this supply route.MethodsData were retrospectively collected from five patients who underwent embolization for thoracic duct collateral leakage in persistent high-output chylothorax after thoracic surgery. Extravasation of lipiodol at the ruptured thoracic duct collaterals was confirmed in all patients on lymphangiography. Transcatheter thoracic ductography was used to identify extravasation of iodinated contrast agent and to identify communication between the thoracic duct and leakage site. Thoracic duct embolization (TDE) was performed using the percutaneous transabdominal approach to cut off the supply route using N-butyl cyanoacrylate (NBCA) mixed with lipiodol (1:5–1:20).ResultsClinical success (drainage volume ≤10 mL/kg/day within 7 days after TDE) was achieved in all patients. The collateral routes developed as consequence of surgical thoracic duct ligation. In three patients, NBCA-Lipiodol reached the leakage site through direct communication between the thoracic duct and the ruptured lymphatic duct. In the other two patients, direct communication and extravasation was not detected on thoracic ductography, and NBCA-Lipiodol did not reach the leakage site. However, NBCA-Lipiodol did reach the cisterna chyli, lumbar trunks, and some collateral routes via the cisterna chyli or lumbar lymphatics. As a result, leakage was stopped.ConclusionsTDE was effective for the management of leakage of the collaterals in high-output chylothorax after thoracic surgery.

    Recent papers suggest protective ventilation (PV) as a primary ventilation strategy during one-lung ventilation (OLV) to reduce postoperative pulmonary morbidity. However, data regarding the advantage of the PV strategy in patients with normal preoperative pulmonary function are inconsistent, especially in the case of minimally invasive thoracic surgery. Therefore we compared conventional OLV (VT 10 ml/kg, FiO2 1.0, zero PEEP) to protective OLV (VT 6 ml/kg, FiO2 0.5, PEEP 5 cmH2O) in patients with normal preoperative pulmonary function tests undergoing video-assisted thoracic surgery. Oxygenation, respiratory mechanics, plasma interleukin-6 and malondialdehyde levels were measured at baseline, 15 and 60 minutes after OLV and 15 minutes after restoration of two-lung ventilation. PaO2 and PaO2/FiO2 were higher in conventional OLV than in protective OLV (PProtective ventilation did not provide advantages over conventional ventilation for video-assisted thoracic surgery in this group of patients with normal lung function.

    We report a case of a 35-year-old woman affected by costal exostosis, originating from the posterior arc of the left fifth rib, who complained of a persistent intractable neuralgia in the left T5 dermatome. Both pain and the risk of visceral injury led us to resect exostosis. The procedure was performed using a uniportal videothoracoscopic approach without additional incisions. For bone resection, we used Piezosurgery, a soft tissue-sparing system based on ultrasound vibrations. Piezosurgery allowed the complete resection of exostosis without injuring the intercostal nerve and vessels. The histologic analysis confirmed the diagnosis of osteochondroma and showed no sign of malignancy. The patient was discharged 2 days after the operation. Considering the lack of symptoms, the low risk of degeneration, and the absence of recurrence at 12-month follow-up, the simple resection of exostosis without performing a more extensive rib resection was judged to be optimal.

    With the progress of antibiotic therapy, the mortality of lung abscess has been improved, and surgical intervention has declined. However, surgery is still required in selected cases that are intractable to antibiotic treatment. Video-assisted thoracoscopic surgery (VATS) is beneficial for treatment and/or diagnosis of pulmonary disease as it provides a less invasive surgical technique and reduces prolongation of post-operative recovery. However, the indication of VATS lobectomy for lung abscess is controversial as a result of particular complications, i.e. wet lung, intrapleural adhesion and ease of bleeding. We herein report a rare combination of lung abscess and osteomyelitis of mandible resulting from the same pathogen successfully treated with VATS lobectomy. We propose VATS lobectomy for lung abscess. This procedure might be the best treatment candidate for selected cases of lung abscess. © 2014 John Wiley & Sons Ltd.

    Synchronous cancers are not such rare clinical conditions. Nevertheless, even after the 8th edition of the TNM classification of the lung cancer, the surgical approach for patients presenting with synchronous bilateral lung cancer is still under debate. The resection of both lesions in the case of synchronous bilateral lung cancer is reasonable, but, on the other hand, is the lobectomy the correct choice in the event of the single primary with a contralateral metastatic lesion? In this case report, we describe how the molecular analysis and the detection of the EGFR, KRAS and TP53 mutations in both tumours have determined in a patient the two tumours as primary and both the right surgical approach. We also discuss how molecular analysis found differences in all the three genes examined in the two lesions and allowed to exclude the clonal nature of the two tumours. In conclusion, genetic studies help to offer a more radical surgical treatment to this patient.

    use of videothoracoscopy in cardiac surgery using cardiopulmonary bypass (CPB. METHODS: Between February 2006 and November 2008, 102 patients underwent consecutively minimally invasive video-assisted cardiac surgery. The cardiac pathologies approached were: mitral valvopathy (n=56, aortic (n=14, interatrial communication (IC (n=32, six patients presented associated tricuspid insufficiency and 12 presented atrial fibrillation. The age ranged from 18 to 68 years and 57 were female. The surgical approach was: femoral arterial and venous cannulation, minithoracotomy ranging from four to six centimeters (cm at the level of the 3º or 4º right intercostal space (RICS, depending on the pathology of the patient, between anterior axillary line and hemiclavicular line, submammary or right periareolar groove through the right breast and thoracoscopy. RESULTS: The surgical procedures were: plasty (n=20 or mitral valve replacement (n=36, aortic valve replacement (n=14, atrioseptoplasty using pericardial patch (n=32, tricuspid valve repair with rigid ring (n=6 and surgical correction of atrial fibrillation with radiofrequency (n=12. There were no complications during the procedures. There was no conversion to thoracotomy in neither case. Two patients developed atrial fibrillation in the postoperative period. There was an episode of stroke seven days after the hospital discharge and one death (0.9% due to systemic inflammatory response syndrome (SIRS. CONCLUSION: This study demonstrates the coverage of pathologies that are possible to be approached by video-assisted cardiac surgery with cardiopulmonary bypass being a safe and effective procedure with low morbimortality. Minimally invasive video-assisted cardiac surgery is already a reality in Brazil, demonstrating excellent aesthetic and functional results

    In recent years, Da Vinci robot system applied in the treatment of intrathoracic surgery mediastinal diseases become more mature. The aim of this study is to summarize the clinical data about mediastinal lesions of General Hospital of Shenyang Military Region in the past 4 years, then to analyze the treatment effect and promising applications of da Vinci robot system in the surgical treatment of mediastinal lesions. 203 cases of mediastinal lesions were collected from General Hospital of Shenyang Military Region between 2010 and 2013. These patients were divided into two groups da Vinci and video-assisted thoracoscopic surgery (VATS) according to the selection of the treatments. The time in surgery, intraoperative blood loss, postoperative drainage amount within three days after surgery, the period of bearing drainage tubes, hospital stays and hospitalization expense were then compared. All patients were successfully operated, the postoperative recovery is good and there is no perioperative death. The different of the time in surgery between two groups is Robots group 82 (20-320) min and thoracoscopic group 89 (35-360) min (P>0.05). The intraoperative blood loss between two groups is robot group 10 (1-100) mL and thoracoscopic group 50 (3-1,500) mL. The postoperative drainage amount within three days after surgery between two groups is robot group 215 (0-2,220) mL and thoracoscopic group 350 (50-1,810) mL. The period of bearing drainage tubes after surgery between two groups is robot group 3 (0-10) d and thoracoscopic group: 5 (1-18) d. The difference of hospital stays between two groups is robot group 7 (2-15) d and thoracoscopic group 9 (2-50) d. The hospitalization expense between two groups is robot group (18,983.6±4,461.2) RMB and thoracoscopic group (9,351.9±2,076.3) RMB (All Pda Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach, even though its expense is higher.

    Full Text Available Purpose. The purpose of this paper is to present results of a single-center, nonrandomized, prospective study of the video-assisted anal fistula treatment (VAAFT. Methods. 68 consecutive patients with perianal fistulas were operated on using the VAAFT technique. 30 of the patients had simple fistulas, and 38 had complex fistulas. The mean follow-up time was 31 months. Results. The overall healing rate was 54.41% (37 of the 68 patients healed with no recurrence during the follow-up period. The results varied depending on the type of fistula. The success rate for the group with simple fistulas was 73.3%, whereas it was only 39.47% for the group with complex fistulas. Female patients achieved higher healing rates for both simple (81.82% versus 68.42% and complex fistulas (77.78% versus 27.59%. There were no major complications. Conclusions. The results of VAAFT vary greatly depending on the type of fistula. The procedure has some drawbacks due to the rigid construction of the fistuloscope and the diameter of the shaft. The electrocautery of the fistula tract from the inside can be insufficient to close wide tracts. However, low risk of complications permits repetition of the treatment until success is achieved. Careful selection of patients is advised.

  20. Using a Bedside Video-assisted Test Tube Test to Assess Stoma Viability: A Report of 4 Cases.

    2016-07-01

    Mucosal discoloration of an intestinal stoma may indicate self-limited venous congestion or necrosis necessitating operative revision. A common bedside technique to assess stoma viability is the "test tube test". A clear tube is inserted into the stoma and a hand-held light is used to assess the color of the stoma. A technique (video-assisted test tube test [VATTT]) developed by the authors utilizes a standard video bronchoscope inserted into a clear plastic blood collection tube to visually inspect and assess the mucosa. This technique was evaluated in 4 patients (age range 49-72 years, all critically ill) with a discolored stoma after emergency surgery. In each case, physical exam revealed ischemic mucosa at the surface either immediately after surgery or after worsening hypotension weeks later. Serial test tube test assessments were ambiguous when trying to assess deeper mucosa. The VATTT assessment showed viable pink mucosa beneath the surface and until the fascia was revealed in 3 patients. One (1) patient had mucosal ischemia down to the fascia, which prompted operative revision of the stoma. The new stoma was assessed with a VATTT and was viable for the entire length of the stoma. VATTT provided an enhanced, magnified, and clearer way to visually assess stoma viability in the postoperative period that can be performed at the bedside with no adverse events. It may prevent unnecessary relaparotomy or enable earlier diagnosis of deep ostomy necrosis. Validity and reliability studies are warranted.

    Background Whether or not uniportal video-assisted thoracoscopic surgery (VATS) is beneficial for spontaneous pneumothorax remains inconclusive. This meta-analysis aimed to summarize the available evidence to assess the feasibility and advantages of uniportal VATS for the treatment of spontaneous pneumothorax compared with three-port VATS. Methods Eligible publications were identified by searching the Cochrane Library, PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data databases and CQVIP. Odds ratios (OR) and standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated to compare dichotomous and continuous variables, respectively. Results This meta-analysis was based on 17 studies and included a total of 988 patients with spontaneous pneumothorax. No death was reported during the perioperative period. Compared with three-port VATS groups, there was a statistically significant difference in uniportal VATS groups regarding postoperative hospital stay (SMD= −0.58; 95% CI: −1.04 to −0.12; P=0.01), paresthesia (OR=0.13; 95% CI: 0.07 to 0.24; Pparesthesia as well as an improvement in patients’ satisfaction. This meta-analysis indicated that using uniportal VATS to treat spontaneous pneumothorax was safe and feasible, and it may be a better alternative procedure because of its advantage in reducing postoperative pain and paresthesia.

    We developed video-assisted neck surgery (VANS) - a feasible, simple, and safe endoscopic thyroid procedure with cosmetic benefits - in 1998. To date, we have performed this procedure 633 times. We have also introduced the VANS method in Belarus, a country that was left contaminated by the Chernobyl nuclear disaster. From a mass screening, nine Belarusian patients, including two with papillary carcinoma of the thyroid, were selected to undergo an operation using the VANS method, performed by a single surgeon (author Shimizu). We compared indicating factors for minimally invasive surgery, specifically the operating time and blood loss, between the Belarusian cases and the 33 most recent cases performed at our institute in Tokyo. The procedures in Belarus were performed under very different working conditions than in Japan. However, operating time and blood loss improved for the Belarusian cases as the surgeon gained experience in this environment; all the cosmetic outcomes were excellent. Subsequently, over a 2-year period, surgeons in Belarus performed the VANS method, with modification, for 29 cases of thyroid tumor. The VANS method is easily learned by inexperienced surgeons without major technical problems. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    During the last three decades, minimally invasive surgery has become common practice in all kinds of surgical disciplines and, in Thoracic Surgery, the minimally invasive approach is recommended as the treatment of choice for early-stage non-small cell lung cancer. Nevertheless, all over the world a large number of lobectomies is still performed by conventional open thoracotomy and not as video-assisted thoracic surgery (VATS), which shows the need of a proper training for this technique. Development and improvement of surgical skills are not only challenging and time-consuming components of the training curriculum for resident or fellow surgeons, but also for more experienced consultants learning new techniques. The rapid evolution of medical technologies like VATS or robotic surgery requires an evolution of the existing educational models to improve cognitive and procedural skills before reaching the operating room in order to increase patient safety. Nowadays, in the Thoracic Surgery field, there is a wide range of simulation-based training methods for surgeons starting or wanting to improve their learning curve in VATS. Aim is to overcome the learning curve required to successfully master this new technique in a brief time. In general, the basic difference between the various learning techniques is the distinction between "dry" and "wet" lab modules, which mainly reflects the use of synthetic or animal-model-based materials. Wet lab trainings can be further sub-divided into in vivo modules, where living anaesthetized animals are used, and ex vivo modules, where only animal tissues serve as basis of the simulation-based training method. In the literature, the role of wet lab in Thoracic Surgery is still debated.

    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. 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. 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.

    A case of thoracic myelopathy with alkaptonuria (ochronotic spondyloarthropathy) is presented. To present and review the first reported case of an alkaptonuric patient with concomitant thoracic myelopathy. Alkaptonuria, a rare hereditary metabolic disease, is characterized by accumulation of homogentistic acid, ochronosis, and destruction of connective tissue resulting in degenerative spondylosis and arthritis. Despite the high incidence of intervertebral disc diseases among patients with alkaptonuria, neurologic symptoms caused by spinal disease are rare. Thoracic myelopathy in a patient with alkaptonuria has not been previously reported. The clinical course, radiologic features, pathology, and treatment outcome of an alkaptonuria patient with thoracic myelopathy was documented. Myelopathy of the patient was caused by rupture of a thoracic intervertebral disc. The neurologic symptoms of the patient were markedly improved after surgery. We have reported for the first time, that an alkaptonuria patient showed thoracic myelopathy caused by rupture of a thoracic intervertebral disc. Decompression followed by the instrumented fusion of the thoracic spine was effective for improving the neurologic symptoms.

    Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

    Full Text Available It has been suggested that video-assisted (VATS lobectomy is safer than open lobectomy in patients with compromised lung function, but data regarding this are limited. We assessed acute outcomes of VATS compared to open lobectomy in these high-risk patients using a systematic literature review and meta-analysis of data.The databases PubMed and Scopus were searched for studies published between 2000 and 2013 that reported mortality and morbidity of VATS in high-risk lung cancer patients defined as having compromised pulmonary or cardiopulmonary function. Study selection, data collection and critical assessment of the included studies were performed according to the recommendations of the Cochrane Collaboration.Three case-control studies and three case series that included 330 VATS and 257 open patients were identified for inclusion. Operative mortality, overall morbidity and pulmonary morbidity were 2.5%, 39.3%, 26.2% in VATS patients and 7.8%, 57.5%, 45.5% in open lobectomy group, respectively. VATS lobectomy patients experienced significantly lower pulmonary morbidity (RR = 0.45; 95% CI, 0.30 to 0.67; p = 0.0001, somewhat reduced operative mortality (RR = 0.51; 95% CI, 0.24 to 1.06; p = 0.07, but no significant difference in overall morbidity (RR = 0.68; 95% CI, 0.41 to 1.14; p = 0.14.The existing data suggest that VATS lobectomy is associated with lower risk for pulmonary morbidity compared with open lobectomy in lung cancer patients with compromised lung function.

    Full Text Available A workshop of experts from France, Germany, Italy and the United States took place at Humanitas Research Hospital Milan, Italy, on 10-11 February 2016, to examine techniques for and applications of robotic surgery to thoracic oncology. The main topics of presentation and discussion were: robotic surgery for lung resection; robot-assisted thymectomy; minimally invasive surgery for esophageal cancer; new developments in computer-assisted surgery and medical applications of robots; the challenge of costs; and future clinical research in robotic thoracic surgery. The following article summarizes the main contributions to the workshop. The Workshop consensus was that, since video-assisted thoracoscopic surgery (VATS is becoming the mainstream approach to resectable lung cancer in North America and Europe, robotic surgery for thoracic oncology is likely to be embraced by an increasing numbers of thoracic surgeons, since it has technical advantages over VATS, including intuitive movements, tremor filtration, more degrees of manipulative freedom, motion scaling, and high definition stereoscopic vision. These advantages may make robotic surgery more accessible than VATS to trainees and experienced surgeons, and also lead to expanded indications. However the high costs of robotic surgery and absence of tactile feedback remain obstacles to widespread dissemination. A prospective multicentric randomized trial (NCT02804893 to compare robotic and VATS approaches to stage I and II lung cancer will start shortly.

A prospective multicentric randomized trial (NCT02804893) to compare robotic and VATS approaches to stages I and II lung cancer will start shortly.

    As an adjunct to simulation-based teaching, laparoscopic video-based surgical coaching has been an effective tool to augment surgical education. However, the wide use of video review in open surgery has been limited primarily due to technological and logistical challenges. The aims of our study were to (1) evaluate perceptions of general surgery (GS) residents on video-assisted operative instruction and (2) conduct a pilot study using a head-mounted GoPro in conjunction with the operative performance rating system to assess feasibility of providing video review to enhance operative feedback during open procedures. GS residents were anonymously surveyed to evaluate their perceptions of oral and written operative feedback and use of video-based operative resources. We then conducted a pilot study of 10 GS residents to assess the utility and feasibility of using a GoPro to record resident performance of an arteriovenous fistula creation with an attending surgeon. Categorical variables were analyzed using the chi-square test. Academic, tertiary medical center. GS residents and faculty. A total of 59 GS residents were anonymously surveyed (response rate = 65.5%). A total of 40% (n = 24) of residents reported that structured evaluations rarely or never provided meaningful feedback. When feedback was received, 55% (n = 32) residents reported that it was only rarely or sometimes in regard to their operative skills. There was no significant difference in surveyed responses among junior postgraduate year (PGY 1-2), senior (PGY 3-4), or chief residents (PGY-5). A total of 80% (n = 8) of residents found the use of GoPro video review very or extremely useful for education; they also deemed video review more useful for operative feedback than written or communicative feedback. An overwhelming majority (90%, n = 9) felt that video review would lead to improved technical skills, wanted to review the video with the attending surgeon for further feedback, and desired expansion of

    Full Text Available Background and objective The development of image technology has led to increasing detection of pulmonary small nodules year by year, but the determination of their nature before operation is difficult. This clinical study aimed to investigate the necessity and feasibility of surgical resection of pulmonary small nodules through a minimally invasive approach and the operational manner of non-small cell lung cancer (NSCLC. Methods The clinical data of 129 cases with pulmonary small nodule of 10 mm or less in diameter were retrospectively analyzed in our hospital from December 2013 to November 2016. Thin-section computed tomography (CT was performed on all cases with 129 pulmonary small nodules. CT-guided hook-wire precise localization was performed on 21 cases. Lobectomy, wedge resection, and segmentectomy with lymph node dissection might be performed in patients according to physical condition. Results Results of the pathological examination of 37 solid pulmonary nodules (SPNs revealed 3 primary squamous cell lung cancers, 3 invasive adenocarcinomas (IAs, 2 metastatic cancers, 2 small cell lung cancers (SCLCs, 16 hamartomas, and 12 nonspecific chronic inflammations. The results of pathological examination of 49 mixed ground glass opacities revealed 19 IAs, 6 micro invasive adenocarcinomas (MIAs, 4 adenocarcinomas in situ (AIS, 1 atypical adenomatous hyperplasia (AAH, 1 SCLC, and 18 nonspecific chronic inflammations. The results of pathological examination of 43 pure ground glass opacities revealed 19 AIS, 6 MIAs, 6 IA, 6 AAHs, and 6 nonspecific chronic inflammations. Wedge resection under video-assisted thoracoscopic surgery (VATS was performed in patients with 52 benign pulmonary small nodules. Lobectomy and systematic lymph node dissection under VATS were performed in 33 patients with NSCLC. Segmentectomy with selective lymph node dissection, wedge resection, and selective lymph node dissection under VATS were performed in six patients with

    Tracheobronchial stenosis is common in the thoracic surgery service, and iatrogenic injury of the airway after manipulation is not infrequent. When a digital thoracic drainage system came onto the market, many advantages were evident. A 24-year-old woman with critical right main bronchial stenosis underwent airway dilation that was complicated by a tear with a massive air leak, resulting in a total right pneumothorax. We employed a pleural drain connected to a digital thoracic drainage system. The drain was removed 2 days after successful resolution of the air leak. © The Author(s) 2015.

    The authors analyzed all cases of thoracic esophagel carcinoma seen from 1980 to 1984 inclusive, plus an additional 22 cases from a pilot study at Wayne State University. Most patients received preoperative combination radiation and chemotherapy. Eighty-nine patients completed treatment (5-fluorouracil, cisplatin, and radiation therapy) as in both the RTOG and SWOG national studies. Of these 89, 39 refused or were not offered planned surgery. Four patients are still alive and well. Fifty patients underwent esophagectomy; 12 patients were free of tumor at esophagectomy, and four of these are alive and well. One patient with a tumor in the resected esophagus alone is still alive. Twenty-two patients were enrolled in the pilot study in which surgery was reserved for salvage, the initial radiation volume was increased, the tumor dose was increased to 5,000 rad give continuously, and chemotherapy was increased to four courses

    Jeune syndrome (asphyxiating thoracic dystrophy) is a rare disorder characterized by skeletal dysplasia, reduced diameter of the thoracic cage and extrathoracic organ involvement. Fatal, early respiratory insufficiency may occur. Two-stage lateral thoracic expansion has been reported, addressing each side sequentially over 3-12 months. While staged repair theoretically provides less invasive surgery in a small child with respiratory distress, we utilized a single stage, bilateral procedure aiming to rapidly maximize lung development. Combined bilateral surgery also offered the chance of rapid recovery, and reduced hospital stay. We present our early experience of this modification of existing surgical treatment for an extremely rare condition, thought to be generally fatal in early childhood. Nine children (6 males, 3 females; median age 30 months [3.5-75]) underwent thoracic expansion for Jeune syndrome in our centre. All patients required preoperative respiratory support (5 with tracheostomy, 8 requiring positive pressure ventilation regularly within each day/night cycle). Two children underwent sequential unilateral (2-month interval between stages) and 7 children bilateral thoracic expansion by means of staggered osteotomies of third to eighth ribs and plate fixation of fourth to fifth rib and sixth to seventh rib, leaving the remaining ribs floating. There was no operative mortality. There were 2 deaths within 3 months of surgery, due to pulmonary hypertension (1 following two-stage and 1 following single-stage thoracic expansion). At the median follow-up of 11 months (1-15), 3 children have been discharged home from their referring unit and 2 have significantly reduced respiratory support. One child remains on non-invasive ventilation and another is still ventilated with a high oxygen requirement. Jeune syndrome is a difficult condition to manage, but bilateral thoracic expansion offers an effective reduction in ventilator requirements in these children

    Blunt trauma to the chest results from transfer of kinetic energy to the human body. It may cause a wide range of mostly life-threatening injuries, including fractures of the thoracic skeleton, disintegration of the pleural space, contusion or laceration of pulmonary parenchyma and damage to the mediastinal structures. For a systematic approach it may be helpful to follow an organ-based evaluation of thoracic trauma. However, it should be borne in mind that subtle injuries may be associated with serious complications. Trauma to the chest may affect different anatomic compartments at the same time, requiring and extending diagnostic approach. Conventional radiography plays a major role in diagnosting thoracic trauma, complemented by ultrasound examination of the pleura and abdomen. It is well documented that CT scanning represents a major technological improvement for assessment of thoracic trauma. With the advent of fast helical CT scanning this method becomes more applicable for severly traumatized patients and potentially replaces other time-consuming procedures. State-of-the-art imaging of both projection and cross-sectional techniques provides useful information for immediate and appropriate treatment mandatory in patients with thoracic trauma. (orig.) [de

    During video-assisted thoracic surgery (VATS), localization is sometimes needed to detect a target lesion that is too small and/or too far from the pleura. In 1995, Kanazawa et al. developed short hookwire and suture system. Since then, this system has been placed often for selected targets before VATS in Japan. This short hookwire and suture system is a representative preoperative localization method and the placement procedure is well-established. Its placement success rates are very high (range: 97.6%-99.6%), and dislodgement of this short hookwire rarely occurs with an incidence of 0.4%-2.5%. The most common complication of short hookwire placement is pneumothorax (incidence: 32.1%-68.1%), followed by pulmonary hemorrhage (incidence: 8.9%-41.6%). Complications are frequent; however, most complications are minor and asymptomatic. Copyright © 2018 Société française de radiologie. Published by Elsevier Masson SAS. All rights reserved.

    OBJECTIVE Pedicle screw fixation is a technique widely used to treat conditions ranging from spine deformity to fracture stabilization. Pedicle screws have been used traditionally in the lumbar spine; however, they are now being used with increasing frequency in the thoracic spine as a more favorable alternative to hooks, wires, or cables. Although safety concerns, such as the incidence of adjacent-segment disease (ASD) after cervical and lumbar fusions, have been reported, such issues in the thoracic spine have yet to be addressed thoroughly. Here, the authors review the literature on ASD after thoracic pedicle screw fixation and report their own experience specifically involving the use of pedicle screws in the thoracic spine. METHODS Select references from online databases, such as PubMed (provided by the US National Library of Medicine at the National Institutes of Health), were used to survey the literature concerning ASD after thoracic pedicle screw fixation. To include the authors' experience at Rutgers New Jersey Medical School, a retrospective review of a prospectively maintained database was performed to determine the incidence of complications over a 13-year period in 123 consecutive adult patients who underwent thoracic pedicle screw fixation. Children, pregnant or lactating women, and prisoners were excluded from the review. By comparing preoperative and postoperative radiographic images, the occurrence of thoracic ASD and disease within the surgical construct was determined. RESULTS Definitive radiographic fusion was detected in 115 (93.5%) patients. Seven incidences of instrumentation failure and 8 lucencies surrounding the screws were observed. One patient was observed to have ASD of the thoracic spine. The mean follow-up duration was 50 months. CONCLUSIONS This long-term radiographic evaluation revealed the use of pedicle screws for thoracic fixation to be an effective stabilization modality. In particular, ASD seems to be less of a problem in the

    The concept of personalized medicine, which aims to provide patients with targeted therapies while greatly reducing surgical trauma, is gaining popularity among Asian clinicians. Single port video-assisted thoracic surgery (VATS) has rapidly gained popularity in Hong Kong for major lung resections, despite bringing new challenges such as interference between surgical instruments and insertion of the optical source through a single incision. Novel types of endocutters and thoracoscopes can help reduce the difficulties commonly encountered during single-port VATS. Our region has been the testing ground and has led the development of many of these innovations. Performing VATS, in particular single-port VATS in hybrid operating theatre helps to localise small pulmonary lesions with real-time images, thus increasing surgical accuracy and pushes the boundaries in treating subcentimeter diseases. Such approach may be assisted by use of electromagnetic navigational bronchoscopy in the same setting. In addition, sublobar resection can also be more individualised according to pathologic tumour subtype that require rapid intraoperative diagnostic test to guide appropriate surgical therapy. A focus on technology and innovation for large tumours that require chest wall resection and reconstructions have also been on going, with new materials and prostheses that may be tailored to each individual needs. The current paper reviews the literature pertaining to the above topics and discusses recent related innovations in Hong Kong, highlighting the study results and future perspectives.

    Video-assisted thoracoscopic surgery (VATS) is a minimally invasive technique that allows a faster recovery after thoracic surgery. Although enhanced recovery after surgery (ERAS) principles seem reasonably applicable to thoracic surgery, there is little literature on the application of such a strategy in this context. In regard to pain management, ERAS pathways promote the adoption of a multimodal strategy, tailored to the patients. This approach is based on combining systemic and loco-regional analgesia to favour opioid-sparing strategies. Thoracic paravertebral block is considered the first-line loco-regional technique for VATS. Other techniques include intercostal nerve block and serratus anterior plane block. Nonsteroidal anti-inflammatory drugs and paracetamol are essential part of the multimodal treatment of pain. Also, adjuvant drugs can be useful as opioid-sparing agents. Nevertheless, the treatment of postoperative pain must take into account opioid agents too, if necessary. All above is useful for careful planning and execution of a multimodal analgesic treatment to enhance the recovery of patients. This article summarizes the most recent evidences from literature and authors' experiences on perioperative multimodal analgesia principles for implementing an ERAS program after VATS lobectomy.

It is a significant cause of mortality. Multidetector computed tomography (MDCT has been an increasingly used method to evaluate chest trauma because of its high success in detecting tissue and organ injuries. Herein, we aimed to present MDCT findings in patients with blunt and penetrating chest trauma admitted to our department. Methods: A total of 240 patients admitted to the emergency department of our hospital between April 2012 and July 2013 with a diagnosis of chest trauma who underwent MDCT evaluations were included. Most of the patients were male (83.3% and victims of a blunt chest trauma. The images were analyzed with respect to the presence of fractures of bony structures, hemothorax, pneumothorax, mediastinal organ injury, and pulmonary and vascular injuries. Results: MDCT images of the 240 patients yielded a prevalence of 41.7% rib fractures, 11.2% scapular fractures, and 7.5% clavicle fractures. The prevalence of thoracic vertebral fracture was 13.8% and that of sternal fracture was 3.8%. The prevalence of hemothorax, pneumothorax, pneumomediastinum, and subcutaneous emphysema was 34.6%, 62.1%, 9.6%, and 35.4%, respectively. The prevalence of rib, clavicle, and thoracic vertebral fractures and pulmonary contusion was higher in the blunt trauma group, whereas the prevalence of hemothorax, subcutaneous emphysema, diaphragmatic injury, and other vascular lacerations was significantly higher in the penetrating trauma group than in the blunt trauma group (p<0.05. Conclusion: MDCT images may yield a high prevalence of fracture of bony structures, soft tissue lacerations, and vascular lesions, which should be well understood by

    Full Text Available Abstract Background Trunk asymmetry and vertebral rotation, at times observed in the normal spine, resemble the characteristics of adolescent idiopathic scoliosis (AIS. Right thoracic curvature has also been reported in the normal spine. If it is determined that the features of right thoracic side curvature in the normal spine are the same as those observed in AIS, these findings might provide a basis for elucidating the etiology of this condition. For this reason, we investigated right thoracic curvature in the normal spine. Methods For normal spinal measurements, 1,200 patients who underwent a posteroanterior chest radiographs were evaluated. These consisted of 400 children (ages 4-9, 400 adolescents (ages 10-19 and 400 adults (ages 20-29, with each group comprised of both genders. The exclusion criteria were obvious chest and spinal diseases. As side curvature is minimal in normal spines and the range at which curvature is measured is difficult to ascertain, first the typical curvature range in scoliosis patients was determined and then the Cobb angle in normal spines was measured using the same range as the scoliosis curve, from T5 to T12. Right thoracic curvature was given a positive value. The curve pattern was organized in each collective three groups: neutral (from -1 degree to 1 degree, right (> +1 degree, and left ( Results In child group, Cobb angle in left was 120, in neutral was 125 and in right was 155. In adolescent group, Cobb angle in left was 70, in neutral was 114 and in right was 216. In adult group, Cobb angle in left was 46, in neutral was 102 and in right was 252. The curvature pattern shifts to the right side in the adolescent group (p Conclusions Based on standing chest radiographic measurements, a right thoracic curvature was observed in normal spines after adolescence.

    Cases of septic pulmonary embolism (SPE) diagnosed clinically by CT after dental extraction rarely include verification of bacteria from the local infection site. We report the case of a 70-year-old man without background disease suffering severe pyothrax after dental extraction. We detected two species of oral bacteria from his pleural effusion. Treatment was so difficult that it required surgical debridement by video assisted thoracoscopic surgery (VATS), even after the appropriate administration of antibiotics. According to the American Heart Association (AHA) prophylaxis guidelines for preventing infective endocarditis indicate that it is uncommon to prescribe antibiotics to patients without background disease after dental extraction. No appropriate Japanese guidelines exist considering the prevention of SPE causing severe pyothorax as in our case. The hematogenous spread of bacteria such as SPE caused by sepsis after tooth extraction thus requires more attended careful consideration in clinical practice if patients are to be properly protected against potentially serious complications.

    Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

    There is no current consensus on which lumen an airway exchange catheter (AEC) should be passed through in double-lumen endotracheal tube (DLT) to exchange for a single-lumen endotracheal tube (SLT) after thoracic surgery. We report an unusual case to provide possible solution on this issue. A 71-year-old man with lung adenocarcinoma had an event of a broken exchange catheter used during a DLT replacement with a SLT, after a video-assisted thoracic surgery. The exchange catheter was impinged at the distal tracheal lumen and snapped during manipulation. All three segments of the catheter were retrieved without further airway compromises. Placement of airway tube exchanger into the tracheal lumen of double-lumen tube is a potential contributing factor of the unusual complication. We suggest an exchange catheter be inserted into the bronchial lumen in optimal depth with the adjunct of video laryngoscope, as the safe method for double-lumen tube exchange.

    Full Text Available Introduction. Chylothorax is an accumulation of chyle in the pleural cavity due to a disruption of the thoracic duct. Traumatic chylothoraces are usually a result of a penetrating trauma and disruption of the thoracic duct, but blunt traumatic chylothorax is a rare condition. The aim of this paper is to present a rare case of traumatic chylothorax after blunt thoracic trauma. Case Outline. We present a case of traumatic chylothorax after blunt thoracic trauma in a patient injured in a motor vehicle accident. The patient had a right-sided fracture of rib XI, hydropneumothorax, lung contusion, and signs of pneumomediastinum. We performed thoracic drainage, but a few days later, according to the increase of amount of the fluid daily drained, and the confirmation of laboratory findings of the analyzed fluid, we made a diagnosis of chylothorax and the patient underwent a thoracotomy, where we sutured the thoracic duct. Conclusion. Chylothorax should be considered in patients after chest trauma if they develop a milky pleural effusion. Analysis of pleural fluid and level of triglycerides is important for the diagnosis and treatment of chylothorax.

    AIM: To investigate the features of crush thoracic trauma in Sichuan earthquake victims using chest digital radiography (CDR). METHODS: We retrospectively reviewed 772 CDR of 417 females and 355 males who had suffered crush thoracic trauma in the Sichuan earthquake. Patient age ranged from 0.5 to 103 years. CDR was performed between May 12, 2008 and June 7, 2008. We looked for injury to the thoracic cage, pulmonary parenchyma and the pleura. RESULTS: Antero-posterior (AP) and lateral CDR were obtained in 349 patients, the remaining 423 patients underwent only AP CDR. Thoracic cage fractures, pulmonary contusion and pleural injuries were noted in 331 (42.9%; 95% CI: 39.4%-46.4%), 67 and 135 patients, respectively. Of the 256 patients with rib fractures, the mean number of fractured ribs per patient was 3. Rib fractures were mostly distributed from the 3rd through to the 8th ribs and the vast majority involved posterior and lateral locations along the rib. Rib fractures had a significant positive association with non-rib thoracic fractures, pulmonary contusion and pleural injuries (P < 0.001). The number of rib fractures and pulmonary contusions were significant factors associated with patient death. CONCLUSION: Earthquake-related crush thoracic trauma has the potential for multiple fractures. The high number of fractured ribs and pulmonary contusions were significant factors which needed appropriate medical treatment. PMID:22132298

    This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

    The damage control surgery came up with the philosophy of applying essential maneuvers to control bleeding and abdominal contamination in trauma patients who are within the limits of their physiological reserves. This concept was extended to thoracic injuries, where relatively simple maneuvers can shorten operative time of in extremis patients. This article aims to revise the various damage control techniques in thoracic organs that must be known to the surgeon engaged in emergency care. RESUMO A cirurgia de controle de danos surgiu com a filosofia de se aplicar manobras essenciais para controle de sangramento e contaminação abdominal, em doentes traumatizados, nos limites de suas reservas fisiológicas. Este conceito se estendeu para as lesões torácicas, onde manobras relativamente simples, podem abreviar o tempo operatório de doentes in extremis. Este artigo tem como objetivo, revisar as diversas técnicas de controle de dano em órgãos torácicos, que devem ser de conhecimento do cirurgião que atua na emergência.

    To identify factors determining the surgical outcome of primary cervical and thoracic neuroblastoma. Twenty-six children with primary thoracic neuroblastoma presented over the last 14 years were analysed for age, mode of presentation, tumour histopathology, biology and outcome. Primary thoracic neuroblastoma was presented in 16 boys and 10 girls at a median age of 2 years (range 6 weeks-15 years). The International Neuroblastoma Staging System (INSS) classified these as Stage 1 (8), Stage 2 (5), Stage 3 (6) and Stage 4 (7). Computed tomography defined the tumour location at the thoracic inlet (11), cervical (2), cervico-thoracic (3), mid-thorax (9) and thoraco-abdominal (1). Twenty-two children underwent surgery that allowed an adequate exposure and resection. Surgical resection was achieved after initial biopsy and preoperative chemotherapy in 15 children, whereas primary resection was performed in 7 children. Four patients with Stage 4 disease underwent chemotherapy alone after initial biopsy; of which, two died despite chemotherapy. Favourable outcome after surgical resection and long-term survival was seen in 19 (86.4%) of the 22 children. Three had local recurrence (14 to 21 months postoperatively), all with unfavourable histology on initial biopsy. The prognostic factors that determined the outcome were age and INSS stage at presentation. In this series, all patients under 2 years of age are still alive, while mortality was seen in five older children. Thoracic neuroblastoma in children under 2 years of age irrespective of stage and histology of the tumour results in long-term survival.

    Purpose: To evaluate the feasibility of using the da Vinci robotic system for radioactive seed placement in the wedge resection margin of pigs' lungs. Methods and materials: Video-assisted thoracoscopic wedge resection was performed in the upper and lower lobes in pigs. Dummy 125 I seeds embedded in absorbable sutures were sewn into the resection margin with the aid of the da Vinci robotic system without complications. In the 'loop technique,' the seeds were placed in a cylindrical pattern; in the 'longitudinal,' they were above and lateral to the resection margin. Orthogonal radiographs were taken in the operating room. For dose calculation, Variseed 66.7 (Build 11312) software was used. Results: With looping seed placement, in the coronal view, the dose at 1 cm from the source was 97.0 Gy; in the lateral view it was 107.3 Gy. For longitudinal seed placement, the numbers were 89.5 Gy and 70.0 Gy, respectively. Conclusion: Robotic technology allows direct placement of radioactive seeds into the resection margin by endoscopic surgery. It overcomes the technical difficulties of manipulating in the narrow chest cavity. With the advent of robotic technology, new options in the treatment of lung cancer, as well as other malignant tumors, will become available

    Cerebrovascular accidents are devastating and worrisome complications after thoracic endovascular aortic repair. The aim of this study was to determine cerebrovascular accident predictors after thoracic endovascular aortic repair. Between January 2001 and June 2008, 76 patients treated with thoracic endovascular aortic repair were prospectively enrolled. The study cohort included 61 men; mean age was 65.4 +/- 16.8 years. All patients underwent a specific neurologic assessment on an hourly basis postoperatively to detect neurologic deficits. Cerebrovascular accidents were diagnosed on the basis of physical examination, tomography scan or magnetic resonance imaging, or autopsy. Cerebrovascular accidents occurred in 8 (10.5%) patients, including 4 transient ischemic attack and 4 major strokes. Four cases were observed within the first 24-hours. Multivariable analysis revealed that anatomic incompleteness of the Willis circle (odds ratio [OR] 17.19, 95% confidence interval [CI] 2.10 to 140.66), as well as the presence of coronary artery disease (OR 6.86, 95 CI% 1.18 to 40.05), were independently associated with postoperative cerebrovascular accident development. Overall hospital mortality was 9.2%, with no significant difference for patients hit by cerebrovascular accidents (25.0% vs 7.3%, p = 0.102). Preexisting coronary artery disease, reflecting a severe diseased aorta and anomalies of Willis circle are independent cerebrovascular accident predictors after thoracic endovascular aortic repair procedures. A careful evaluation of the arch vessels and cerebral vascularization should be mandatory for patients suitable for thoracic endovascular aortic repair.

    Full Text Available The advantages of video-assisted cardiac surgery are very necessary for high-risk patients, but subjecting them to possible complications is a big responsibility and a challenge for the cardiovascular anesthesiologist. This article presents the first five cases of video-assisted coronary artery bypass grafting in the country, and describes the anesthetic techniques and results. Also, the advantages of this surgical technique are discussed: less invasive, less postoperative pain, less duration of postoperative intubation and ventilation, minimal risk of infection and bleeding, reduced need for transfusions, and better healing and aesthetics of the wound. It was concluded that although this series is small, we consider it a good option for patients with ischemic heart disease and a single-vessel (anterior descending artery revascularization criterion, not accessible to intervention.

    Two children underwent placement of permanent, epicardial-lead, dual-chamber, unipolar pacemaker systems for complete heart block. Postoperatively, both patients demonstrated subcutaneous emphysema-in the area of their pulse generators-temporally related to thoracic catheter manipulation. Acutely, each situation was managed with manual compression of the pulse generator, ascertaining appropriate pacemaker sensing and pacing. Maintenance of compression with pressure dressings, vigilant observation/monitoring, and education of the care givers resulted in satisfactory pacemaker function without invasive intervention.

    Byssinosis is an occupational disease occurring commonly in cotton mill workers; it usually presents with features of chronic obstructive pulmonary disease (COPD). The management of patients with COPD presents a significant challenges to the anesthetist. Regional anesthesia is preferred in most of these patients to avoid perioperative and postoperative complications related to general anesthesia. We report a known case of Byssinosis who underwent nephrectomy under segmental spinal anesthesia at the low thoracic level.

    Selective conservatism for thoracic trauma is well established but the emergence of new technologies may cause management strategies to continue to evolve. A retrospective study was conducted on thoracic trauma patients managed in a single institution in South Africa over a 4-year period to determine the appropriateness of our current policy of selective conservatism. A total of 1,239 patients were included in the study; 112 required an emergency thoracotomy, 125 were admitted for observation and 1,002 required a tube thoracostomy (TT). Ninety-one per cent of the patients were male and the median age was 24 years. Seventy-five per cent of the cases were penetrating trauma and the remaining were blunt trauma. The indications for TT were pneumothorax (PTX) (n=382, 38%), haemothorax (HTX) (n=300, 30%) and haemopneumothorax (HPTX) (n=320, 32%). A total of 13% (127/1,002) of all chest x-rays (CXR) following tube removal demonstrated residual pathologies that precluded immediate discharge: 32 (8%) in Group A (PTX), 44 (15%) in Group B (HTX) and 51 (16%) in Group C (HPTX). All 32 patients in Group A were simply observed and did not require further intervention. In Group B, 17 patients required repeat TTs and 27 required video assisted thoracoscopic surgery (VATS) for clearance of residual HTX. Twenty-nine patients in Group C required repeat TTs and twenty-two required VATS. The vast majority of patients with thoracic trauma can be managed conservatively with TT alone. Residual pathology appeared to be lowest in patients with a PTX, which seldom requires treatment, while only a minority of patients required repeat TTs or VATS for a retained HTX. Selective conservatism is still appropriate in the current era in a developing world setting.

  14. The evolution of thoracic anesthesia.

    Brodsky, Jay B

    2005-02-01

    The specialty of thoracic surgery has evolved along with the modem practice of anesthesia. This close relationship began in the 1930s and continues today. Thoracic surgery has grown from a field limited almost exclusively to simple chest wall procedures to the present situation in which complex procedures, such as lung volume reduction or lung transplantation, now can be performed on the most severely compromised patient. The great advances in thoracic surgery have followed discoveries and technical innovations in many medical fields. One of the most important reasons for the rapid escalation in the number and complexity of thoracic surgical procedures now being performed has been the evolution of anesthesia for thoracic surgery. There has been so much progress in this area that numerous books and journals are devoted entirely to this subject. The author has been privileged to work with several surgeons who specialized in noncardiac thoracic surgery. As a colleague of 25 years, the noted pulmonary surgeon James B.D. Mark wrote, "Any operation is a team effort... (but) nowhere is this team effort more important than in thoracic surgery, where near-choreography of moves by all participants is essential. Exchange of information, status and plans are mandatory". This team approach between the thoracic surgeon and the anesthesiologist reflects the history of the two specialties. With new advances in technology, such as continuous blood gas monitoring and the pharmacologic management of pulmonary circulation to maximize oxygenation during one-lung ventilation, in the future even more complex procedures may be able to be performed safely on even higher risk patients.

    To describe a practical approach for the diagnosis and treatment of thoracic zygapophyseal joint pain and to present preliminary clinical data on the effects of this treatment approach on health-related quality of life. An observational study. Specialist outpatient pain clinic in northern Sweden. Patients with long-term thoracic pain. We describe a method of radiofrequency denervation of thoracic zygapophyseal joints. We compared health-related quality of life between patients who underwent radiofrequency denervation of thoracic zygapophyseal joints and patients who underwent radiofrequency denervation for lumbar and cervical zygapophyseal joint pain. Treatment according to the Spine Intervention Society Guidelines was performed on the lumbar region in 178 patients and in the cervical region in 55 patients. Another 82 patients were treated in the thoracic region with our proposed technique. A survival plot of improvements in health-related quality of life revealed that all three treatments were effective in 65% or more of patients. The improvement in health-related quality of life was maintained for 12 or more months after treatment in 47% to 51% of patients. Our results suggest that radiofrequency denervation of thoracic zygapophyseal joint pain is as effective as radiofrequency denervation, the standard treatment, for lumbar and cervical zygapophyseal joint pain. If these results can be confirmed by other centers, radiofrequency denervation is likely to become more widely available for the treatment of thoracic zygapophyseal joint pain.

    To decrease the frequency of video-assisted thoracoscopic surgery (VATS) biopsy being used to diagnose inflammatory nodules, we studied the clinicopathological findings of lung cancers and inflammatory nodules diagnosed by VATS or open-lung biopsy. We studied 46 lung cancers and 47 inflammatory nodules smaller than 30 mm in diameter diagnosed by VATS or open-lung biopsy. While the computed tomography (CT) findings were not significantly different between lung cancers and inflammatory nodules, N1 or N2 lung cancers more frequently showed distinct malignant features on CT than T1N0M0 lung cancers (P<0.05). A review of previous chest X-ray films revealed that those of inflammatory nodules showed new nodules more frequently and nodular enlargement less frequently than those of lung cancer (P<0.01). Of 13 lung cancers that showed nodular enlargement during a mean 15-month period, 12 were T1N0M0. Nondiagnosable small lung nodules, which had few malignant features on CT and had newly appeared on a chest X-ray film, were more likely to be inflammatory nodules than lung cancers; and even if they were lung cancers, the tumor stage was usually T1N0M0. Thus, to decrease the incidence of VATS biopsy being performed for inflammatory nodules, intensive follow-up by CT until slight nodular enlargement becomes evident could be a means of revealing nondiagnosable small lung nodules without distinct malignant findings, except for nodules found to be enlarging on a review of retrospective films.

    To assess the feasibility and perioperative outcomes of single-port (SP) and multi-port (MP) approaches for video-assisted thoracoscopic surgery (VATS) lobectomy and anatomical segmentectomy. Retrospective data from 458 patients who received VATS lobectomy or anatomical segmentectomy at Shanghai Chest Hospital, Korea University Guro Hospital, Affiliated Hospital of National Taiwan University, University of Hong Kong Queen Mary Hospital and Shenzhen Hospital were collected. Patients were divided into SP group and MP group according to the surgical approach. Perioperative factors such as operation time, blood loss during surgery, conversion rate, the number and stations of lymph nodes harvested, postoperative chest tube drainage time, postoperative hospitalization time, perioperative morbidity and mortality, and pain scores during the first 3 days after surgery were compared between the two groups. There were no differences in the number (P=0.278) and stations (P=0.564) of lymph nodes harvested, postoperative morbidity (P=0.414) or mortality(P=0.246), and pain score on the third day (P=0.630) after surgery between the two groups. The SP group had a longer operation time (P=0.042) and greater intraoperative blood loss (P<0.001), but the conversion rate was even higher in the MP group (P=0.018). Patients in the SP group had shorter chest tube removal time (P=0.012) and postoperative hospitalization time (P=0.005). Pain scores were lower on the first (P=0.014) and second (P=0.006) day after surgery in the SP group. SP VATS lobectomy and anatomical segmentectomy is technologically more demanding than MP VATS. It can be safe and feasible in the hands of experienced surgeons, with comparable preoperative outcomes to MP VATS, but less pain in the early postoperative period.

    Transbronchial lung cryobiopsy is increasingly being used for the assessment of diffuse parenchymal lung diseases. Several studies have shown larger biopsy samples and higher yields compared with conventional transbronchial biopsies. However, the higher risk of bleeding and other complications has raised concerns for widespread use of this modality. To study the diagnostic accuracy and safety profile of transbronchial lung cryobiopsy and compare with video-assisted thoracoscopic surgery (VATS) by reviewing available evidence from the literature. Medline and PubMed were searched from inception until December 2016. Data on diagnostic performance were abstracted by constructing two-by-two contingency tables for each study. Data on a priori selected safety outcomes were collected. Risk of bias was assessed with the Quality Assessment of Diagnostic Accuracy Studies tool. Random effects meta-analyses were performed to obtain summary estimates of the diagnostic accuracy. The pooled diagnostic yield, pooled sensitivity, and pooled specificity of transbronchial lung cryobiopsy were 83.7% (76.9-88.8%), 87% (85-89%), and 57% (40-73%), respectively. The pooled diagnostic yield, pooled sensitivity, and pooled specificity of VATS were 92.7% (87.6-95.8%), 91.0% (89-92%), and 58% (31-81%), respectively. The incidence of grade 2 (moderate to severe) endobronchial bleeding after transbronchial lung cryobiopsy and of post-procedural pneumothorax was 4.9% (2.2-10.7%) and 9.5% (5.9-14.9%), respectively. Although the diagnostic test accuracy measures of transbronchial lung cryobiopsy lag behind those of VATS, with an acceptable safety profile and potential cost savings, the former could be considered as an alternative in the evaluation of patients with diffuse parenchymal lung diseases.

    It is difficult to evaluate the significant findings of epidural hematoma in magnetic resonance images (MRIs) obtained immediately after thoracic posterior screw fixation (PSF). Prospectively, immediate postoperative MRI was performed in 10 patients who underwent thoracic PSF from April to December 2013. Additionally, we retrospectively analyzed the MRIs from 3 patients before hematoma evacuation out of 260 patients who underwent thoracic PSF from January 2000 to March 2013. The MRI findings of 9 out of the 10 patients, consecutively collected after thoracic PSF, showed neurologic recovery with a well-preserved cerebrospinal fluid (CSF) space and no prominent hemorrhage. Even though there were metal artifacts at the level of the pedicle screws, the preserved CSF space was observed. In contrast, the MRI of 1 patient with poor neurologic outcome demonstrated a typical hematoma and slight spinal cord compression and reduced CSF space. In the retrospective analysis of the 3 patients who showed definite motor weakness in the lower extremities after their first thoracic fusion surgery and underwent hematoma evacuation, the magnetic resonance images before hematoma evacuation also revealed hematoma compressing the spinal cord and diminished CSF space. This study shows that epidural hematomas can be detected on MRI performed immediately after thoracic fixation surgery, despite metal artifacts and findings such as hematoma causing spinal cord compression. Loss of CSF space should be considered to be associated with neurologic deficit. Copyright © 2017 Elsevier Inc. All rights reserved.

    To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for non-cardiac thoracic pathology in fetuses and children, compared with conventional autopsy. Institutional ethics approval and parental consent was obtained. A total of 400 unselected fetuses and children underwent PMMR before conventional autopsy, reported blinded to the other dataset. Of 400 non-cardiac thoracic abnormalities, 113 (28 %) were found at autopsy. Overall sensitivity and specificity (95 % confidence interval) of PMMR for any thoracic pathology was poor at 39.6 % (31.0, 48.9) and 85.5 % (80.7, 89.2) respectively, with positive predictive value (PPV) 53.7 % (42.9, 64.0) and negative predictive value (NPV) 77.0 % (71.8, 81.4). Overall agreement was 71.8 % (67.1, 76.2). PMMR was most sensitive at detecting anatomical abnormalities, including pleural effusions and lung or thoracic hypoplasia, but particularly poor at detecting infection. PMMR currently has relatively poor diagnostic detection rates for the commonest intra-thoracic pathologies identified at autopsy in fetuses and children, including respiratory tract infection and diffuse alveolar haemorrhage. The reasonable NPV suggests that normal thoracic appearances at PMMR exclude the majority of important thoracic lesions at autopsy, and so could be useful in the context of minimally invasive autopsy for detecting non-cardiac thoracic abnormalities.

    Isolated long thoracic nerve palsy results in scapular winging and destabilization. In this study, we review the surgical management of isolated long thoracic nerve palsy and suggest a surgical technique and treatment algorithm to simplify management. In total, 19 patients who required surgery for an isolated long thoracic nerve palsy were reviewed retrospectively. Preoperative demographics, electromyography (EMG), and physical examinations were reviewed. Intraoperative nerve stimulation, surgical decision making, and postoperative outcomes were reviewed. In total, 19 patients with an average age of 32 were included in the study. All patients had an isolated long thoracic nerve palsy caused by either an injury (58%), Parsonage-Turner syndrome (32%), or shoulder surgery (10%); 18 patients (95%) underwent preoperative EMG; 10 with evidence of denervation (56%); and 13 patients had motor unit potentials in the serratus anterior (72%). The preoperative EMG did not correlate with intraoperative nerve stimulation in 13 patients (72%) and did correlate in 5 patients (28%); 3 patients had a nerve transfer (3 thoracodorsal to long thoracic at lateral chest, 1 pec to long thoracic at supraclavicular incision). In the 3 patients who had a nerve transfer, there was return of full forward flexion of the shoulder at an average of 2.5 months. A treatment algorithm based on intraoperative nerve stimulation will help guide surgeons in their clinical decision making in patients with isolated long thoracic nerve palsy. Intraoperative nerve stimulation is the gold standard in the management of isolated long thoracic nerve palsy.

    The use of the Arndt endobronchial blocker has not gained widespread acceptance during video-assisted thoracoscopic surgery (VATS) because of its high cost and longer time to operative lung collapse especially in patients with chronic obstructive pulmonary disease (COPD). The use of a ventilator disconnection technique has been shown to produce a comparable degree of lung collapse when used with either a double-lumen tube or an Arndt endobronchial blocker. We hypothesised that the use of bronchial suction through the suction port of the endobronchial blocker would be associated with a comparable time to achieve optimum lung collapse as the disconnection technique. A randomised, double-blind study. Single university hospital. Fifty-eight patients with spontaneous pneumothorax scheduled for elective VATS using the Arndt endobronchial blocker for one-lung ventilation (OLV). Patients were randomly assigned to one of two groups (n = 29 per group) to deflate the operative lung with either disconnection of the endotracheal tube from the ventilator for 60 s prior to inflation of the endobronchial blocker or connection of a suction pressure of -30 cmH2O to the suction port of the endobronchial blocker through the barrel of a 1 ml syringe. The primary outcome was the time to total lung collapse. Secondary outcomes included surgeon rating of lung collapse, overall surgeon satisfaction, need for further fibreoptic bronchial suction manoeuvres and intraoperative hypoxaemia. The bronchial suction technique was associated with a significantly shorter time to total lung collapse than the disconnection method [93 (95% confidence interval, 95% CI 81.3 to 103.7) vs. 197 (95% CI 157.4 to 237) s respectively; P < 0.001]. Both the disconnection and bronchial suction groups had a comparable surgical rating of excellent lung collapse 40 min after the start of OLV (65.5 vs. 79.3%, respectively; P = 0.24), overall surgeon satisfaction [median (interquartile range, IQR) 9 (8 to 10) vs. 9 (8

    Rheumatoid arthritis is a relatively common multisystem disease associated with significant mortality and morbidity. Thoracic disease, both pleural and pulmonary, is a frequent extra-articular manifestation of rheumatoid arthritis and responsible for approximately 20% of rheumatoid-associated mortality. Rheumatoid disease and its associated therapies can affect all compartments of the lung inciting a range of stereotyped pathological responses and it is not infrequent for multiple disease entities to co-exist. In some instances, development of pulmonary complications may precede typical rheumatological presentation of the disease and be the first indication of an underlying connective tissue disease. The spectrum of thoracic disease related to rheumatoid arthritis is reviewed

    We report a case of vascular thoracic outlet syndrome in a young man, diagnosed with upper limb arteriography, leading to repeated arterio-arterial emboli originating from a post-stenotic subclavian artery aneurysm. It is of our interest due to its low incidence and the small number of cases reported that have been diagnosed by arteriography. The thoracic outlet is the path through which vascular and neural structures goes from the neck to the axilla, and it has three anatomical strictures, that when pronounced, can compress the brachial plexus or subclavian vessels, leading to different symptoms and signs.

    To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far. Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4. All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years. This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

    The aim of this study was to compare the efficiency of different surgical approaches to thoracic disc herniation, and to show the role of segmental fusion and selection of an appropriate microsurgical decompression technique for the successful outcome of surgery. A group of 27 patients, 10 men and 17 women, between 31 and 70 years (average age, 49.33 years) were included in this prospective study. They underwent surgery for thoracic degeneration disc disease in the period from June 1994 to August 2008. In all patients, the severity of myelopathy was assessed using the grading Frankel system and JOA score, axial and radicular pain intensity was evaluated with VAS and ODI rating systems. The diagnosis was established on the basis of thoracic spine radiography, thoracic spine MRI and a CT scan of the segment. A total of 30 thoracic segments, in the range of Th4/Th5 to Th12/L1, were indicated for surgery. Localisation of the hernia was medial at 19 segments, mediolateral at three and lateral at eight segments. Soft disc herniation was found in 17 cases and hard disc protrusion at the remaining 13 segments. Surgery for significant myelopathy was carried out in 23 patients and for pain in four patients. According to the surgical procedure used, the patients were allocated to two groups: group A comprised 10 patients treated without disc replacement through a laminectomy or a costotransversectomy exposure, and group B consisted of 17 patients undergo- ing intersomatic fusion via a thoracotomy. Clinical and radiographic examinations were made at regular intervals for at least 1 year of follow-up. The results of clinical assessment, including JOA scores, JOA Recovery Rate, VAS scores at rest and after exercise and ODI, were statistically analysed for each group and compared. There was a statistically significant difference in JOA evaluation of myelopathy between the groups in group A, the mean JOA score declined from 7.9 to 7.0, i.e., -0.9 point, while in group B it

    Full Text Available Rigid severe post-traumatic thoracic spine deformities result from frequent, recent high-energy trauma in children with an increasing frequency due to a variety of reasons. These types of injuries are commonly followed by spinal cord anatomic injury; therefore, the treatment of these patients warrants special attention from the ethical viewpoint. Generally, the only indication for surgical intervention is spinal dysfunction. Considering this and the patients’ ordinary severe somatic state, surgical trauma should be minimized as much as possible. However, for adequate deformity correction, effective spine stabilization and restoration of liquorodynamics is necessary. Recent studies have reported the successful use of different methods of dorsal interventions (P/VCR in cases with unstable damages in children. Here, we present the case of a 15-year-old boy who underwent surgical treatment for coarse post-traumatic thoracic spine deformity with chronic fracture-dislocation of Th7 vertebra.

    Effective use of postoperative incentive spirometry improves patient outcomes but is limited by pain after thoracic and upper abdominal surgery. Thoracic epidurals are frequently used to provide analgesia and attenuate postoperative pulmonary dysfunction. We hypothesized that, in patients with thoracic epidurals for thoracic and abdominal surgery, high pain scores would be associated with poorer incentive spirometry performance, even when accounting for other variables. Retrospective study of 468 patients who underwent upper abdominal or thoracic surgery using postoperative thoracic epidural analgesia between June 1, 2009, and August 31, 2013, at a single tertiary academic center. The association between incentive spirometry performance and pain was assessed as the primary outcome. Other independent predictors of incentive spirometry performance were also identified. Postoperative incentive spirometry performance was found to be inversely proportional to pain score, which correlated significantly stronger with deep breathing pain compared with pain at rest (-0.33 vs -0.14 on postoperative day 1; -0.23 vs -0.12 on postoperative day 2). Pain with deep breathing was independently associated with poorer incentive spirometry performance in the multivariable linear regression model (P spirometry performance could be used as another indicator of thoracic epidural efficacy. This may be particularly useful in patients reporting high pain scores postoperatively.

    Nanotechnology is an emerging, rapidly evolving field with the potential to significantly impact care across the full spectrum of cancer therapy. Of note, several recent nanotechnological advances show particular promise to improve outcomes for thoracic surgical patients. A variety of nanotechnologies are described that offer possible solutions to existing challenges encountered in the detection, diagnosis and treatment of lung cancer. Nanotechnology-based imaging platforms have the ability to improve the surgical care of patients with thoracic malignancies through technological advances in intraoperative tumour localization, lymph node mapping and accuracy of tumour resection. Moreover, nanotechnology is poised to revolutionize adjuvant lung cancer therapy. Common chemotherapeutic drugs, such as paclitaxel, docetaxel and doxorubicin, are being formulated using various nanotechnologies to improve drug delivery, whereas nanoparticle (NP)-based imaging technologies can monitor the tumour microenvironment and facilitate molecularly targeted lung cancer therapy. Although early nanotechnology-based delivery systems show promise, the next frontier in lung cancer therapy is the development of 'theranostic' multifunctional NPs capable of integrating diagnosis, drug monitoring, tumour targeting and controlled drug release into various unifying platforms. This article provides an overview of key existing and emerging nanotechnology platforms that may find clinical application in thoracic surgery in the near future. © The Author 2016.

    Persistent postoperative pain is an acknowledged entity that reduces daily activities. Evaluation of the post-thoracotomy pain syndrome (PTPS) is often measured using traditional pain scales without in-depth questions on pain impairment. Thus, the purpose was to create a procedure-specific questionnaire for assessment of functional impairment due to PTPS. Activities were obtained from the literature supplemented by interviews with patients and surgeons. The questionnaire was validated using the Rasch model in order to describe an underlying pain impairment scale. Four of 17 questions were redundant. The remaining 13 questions from low to intensive activity described functional impairment following persistent pain from thoracotomy and video-assisted thoracic surgery (VATS). No evidence for differential item functioning for gender, age or differences between open or VATS, were found. A generalized log-linear Rasch model including local dependence was constructed. Though local dependence influenced reliability, the test-retest reliability estimated under the log-linear Rasch model was high (0.88-0.96). Correlation with items from the Disability of the Arm, Shoulder and Hand (quick) questionnaire supported validity (γ = 0.46, P impairment questionnaire measured 2 qualitatively different pain dimensions although highly correlated (γ = 0.76). This study presents method, results and validation of a new unidimensional scale measuring procedure specific functional impairment due to PTPS following open surgery and VATS. Procedure specific tools such as this could provide important outcomes measures for future trials on persistent postsurgical pain states allowing better assessment of interventions (250).

    Thrombus formation in an atherosclerotic or aneurysmal descending thoracic aorta is a well-described, frequently encountered vascular condition. In comparison, thrombus formation in a normal-appearing descending thoracic aorta is reported far less often. We describe the case of a 46-year-old woman who had splenic and renal infarctions secondary to embolic showers from a large, mobile thrombus in a morphologically normal proximal descending thoracic aorta. After the patient underwent anticoagulation, stent-grafting, and surgical bypass to correct an arterial blockage caused by the stent-graft, she resumed a relatively normal life. In contrast with other cases of a thrombotic but normal-appearing descending thoracic aorta, this patient had no known malignancy or systemic coagulative disorders; her sole risk factor was chronic smoking. We discuss our patient's case and review the relevant medical literature, focusing on the effect of smoking on coagulation physiology. PMID:24391341

    Awake craniotomies (AC) could reduce neurological deficits compared with patients under general anesthesia, however, intraoperative seizure is a major reason causing awake surgery failure. The purpose of the study was to give a comprehensive overview the published articles focused on seizure incidence in awake craniotomy. Bibliographic searches of the EMBASE, MEDLINE,were performed to identify articles and conference abstracts that investigated the intraoperative seizure frequency of patients underwent AC. Twenty-five studies were included in this meta-analysis. Among the 25 included studies, one was randomized controlled trials and 5 of them were comparable studies. The pooled data suggested the general intraoperative seizure(IOS) rate for patients with AC was 8%(fixed effect model), sub-group analysis identified IOS rate for glioma patients was 8% and low grade patients was 10%. The pooled data showed early seizure rates of AC patients was 11% and late seizure rates was 35%. This systematic review and meta-analysis shows that awake craniotomy is a safe technique with relatively low intraoperative seizure occurrence. However, few RCTs were available, and the acquisition of further evidence through high-quality RCTs is highly recommended.

    In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

    OBJECTIVE The long-term effects of instrumentation and fusion of the occipital-cervical-thoracic spine on spinal growth in young children are poorly understood. To mitigate the effects of this surgery on the growing pediatric spine, the authors report a novel technique used in 4 children with severe cervical-thoracic instability. These patients underwent instrumentation from the occiput to the upper thoracic region for stabilization, but without bone graft at the craniovertebral junction (CVJ). Subsequent surgery was then performed to remove the occipital instrumentation, thereby allowing further growth and increased motion across the CVJ. METHODS Three very young children (15, 30, and 30 months old) underwent occipital to thoracic posterior segmental instrumentation due to cervical or upper thoracic dislocation, progressive kyphosis, and myelopathy. The fourth child (10 years old) underwent similar instrumentation for progressive cervical-thoracic scoliosis. Bone graft was placed at and distal to C-2 only. After follow-up CT scans demonstrated posterior arthrodesis without unintended fusion from the occiput to C-2, 3 patients underwent removal of the occipital instrumentation. RESULTS Follow-up cervical spine flexion/extension radiographs demonstrated partial restoration of motion at the CVJ. One patient has not had the occipital instrumentation removed yet, because only 4 months have elapsed since her operation. CONCLUSIONS Temporary fixation to the occiput provides increased biomechanical stability for spinal stabilization in young children, without permanently eliminating motion and growth at the CVJ. This technique can be considered in children who require longer instrumentation constructs for temporary stabilization, but who only need fusion in more limited areas where spinal instability exists.

    Full Text Available A 69-year-old man underwent thoracic endovascular aortic repair of a descending aortic aneurysm. Three years later, he developed impending rupture due to aneurysmal expansion that included the proximal landing zone. Urgent open surgery was performed via lateral thoracotomy, and a Dacron graft was sewn to the previous stent graft distally with Teflon felt reinforcement. Postoperatively, four sequential computed tomography scans demonstrated that the aneurysm was additionally increasing in size probably due to continuous hematoma production, suggesting a possibility of endoleaks. This case demonstrates the importance of careful radiologic surveillance after endovascular repair, and also after partial open conversion.

    Full Text Available A hybrid approach to elephant trunk technique for treatment of thoracic aortic aneurysms combines a conventional surgical and endovascular therapy. Compared to surgery alone, there is a presumption that mortality and morbidity is reduced. We present a case report of a 42-year-old man with a giant aneurysm of the entire thoracic aorta, significant aortic and tricuspid regurgitation and ventricular septum defect. The patient underwent multiple consecutive operations and interventions having, among others, finally replaced the entire thoracic aorta with the use of the hybrid elephant trunk technique.

    Guidelines for repair of bicuspid aortic valve-associated ascending thoracic aortic aneurysms have been changing, most recently to the same criteria as tricuspid aortic valve-ascending thoracic aortic aneurysms. Rupture/dissection occurs when wall stress exceeds wall strength. Recent studies suggest similar strength of bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms; thus, comparative wall stress may better predict dissection in bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms. Our aim was to determine whether bicuspid aortic valve-ascending thoracic aortic aneurysms had higher wall stresses than their tricuspid aortic valve counterparts. Patients with bicuspid aortic valve- and tricuspid aortic valve-ascending thoracic aortic aneurysms (bicuspid aortic valve = 17, tricuspid aortic valve = 19) greater than 4.5 cm underwent electrocardiogram-gated computed tomography angiography. Patient-specific 3-dimensional geometry was reconstructed and loaded to systemic pressure after accounting for prestress geometry. Finite element analyses were performed using the LS-DYNA solver (LSTC Inc, Livermore, Calif) with user-defined fiber-embedded material model to determine ascending thoracic aortic aneurysm wall stress. Bicuspid aortic valve-ascending thoracic aortic aneurysms 99th-percentile longitudinal stresses were 280 kPa versus 242 kPa (P = .028) for tricuspid aortic valve-ascending thoracic aortic aneurysms in systole. These stresses did not correlate to diameter for bicuspid aortic valve-ascending thoracic aortic aneurysms (r = -0.004) but had better correlation to tricuspid aortic valve-ascending thoracic aortic aneurysms diameter (r = 0.677). Longitudinal stresses on sinotubular junction were significantly higher in bicuspid aortic valve-ascending thoracic aortic aneurysms than in tricuspid aortic valve-ascending thoracic aortic aneurysms (405 vs 329 kPa, P = .023).

    The treatment of thoracic aortic disease has changed radically with the advances made in endovascular therapy since the concept of thoracic endovascular aortic repair was first described 15 years ago. Currently, there is a diverse array of endografts that are commercially available to treat the thoracic aorta. Multiple studies, including industry-sponsored and single-institution reports, have demonstrated excellent outcomes of thoracic endovascular aortic repair for the treatment of thoracic aortic aneurysms, with less reported perioperative morbidity and mortality in comparison with conventional open repair. Additionally, similar outcomes have been demonstrated for the treatment of type B dissections. However, the technology remains relatively novel, and larger studies with longer term outcomes are necessary to more fully evaluate the role of endovascular therapy for the treatment of thoracic aortic disease. This review examines the currently available thoracic endografts, preoperative planning for thoracic endovascular aortic repair, and outcomes of thoracic endovascular aortic repair for the treatment of both thoracic aortic aneurysms and type B aortic dissections.

    Multicenter retrospective case series. To determine the rate of thoracic duct injury during cervical spine operations. A retrospective case series study was conducted among 21 high-volume surgical centers to identify instances of thoracic duct injury during anterior cervical spine surgery. Staff at each center abstracted data for each identified case into case report forms. All case report forms were collected by the AOSpine North America Clinical Research Network Methodological Core for data processing, cleaning, and analysis. Of a total of 9591 patients reviewed that underwent cervical spine surgery, 2 (0.02%) incurred iatrogenic injury to the thoracic duct. Both patients underwent a left-sided anterior cervical discectomy and fusion. The interruption of the thoracic duct was addressed intraoperatively in one patient with no residual postoperative effects. The second individual developed a chylous fluid collection approximately 2 months after the operation that required drainage via needle aspiration. Damage to the thoracic duct during cervical spine surgery is a relatively rare occurrence. Rapid identification of the disruption of this lymphatic vessel is critical to minimize deleterious effects of this complication.

    Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

    Full Text Available PURPOSE. The aim of our retrospective study was to analyze the patterns of associated thoracic injuries in patients underwent blunt chest trauma and rib fractures. METHODS. The study included 212 patients with rib fractures due to blunt thoracic trauma. The mechanism of trauma, the type of rib fracture and the type of associated injuries were analyzed. RESULTS. The patients were divided in two groups according to the number of fractured ribs-group I included the patients with up to two fractured ribs (72 patients-33,9%, and group II – with ≥3 fractured ribs (140 patients-66,1%. Associated chest injuries were present in 36 of the patients from group I (50%, and in 133 patients from group II (95%. Pulmonary contusion was the most common intrathoracicinjurie-65,6% of the cases. The mean hospital stay was 8, 7 days. The lethality rate was 16,9% -all of them due to the associated chest injuries. CONCLUSIONS. The mortality related to rib fractures is affected by the associated thoracic injuries, the advanced age, and the number of fractured ribs.

  11. Giant thoracic schwannoma presenting with abrupt onset of abdominal pain: a case report

    2009-01-01

    Introduction Giant intradural extramedullary schwannomas of the thoracic spine are not common. Schwannomas, that is, tumors derived from neoplastic Schwann cells, and neurofibromas represent the most common intradural extramedullary spinal lesions. We report the case of a patient with a giant thoracic schwannoma presenting unusually with acute abdominal pain and with delayed neurological impairment. Case presentation A 26-year-old Hispanic man with no previous medical problems presented with acute periumbilical pain. After extensive work-up including an exploratory laparotomy for appendectomy, magnetic resonance imaging scans of the lumbar and thoracic spine revealed a giant intradural extramedullary thoracic schwannoma within the spinal canal posterior to the T9, T10, and T11 vertebral bodies. Magnetic resonance imaging signal prolongation was noted in the spinal cord both rostral and caudal to the schwannoma. The patient underwent an urgent laminectomy from T8 to L1. After sacrificing the T10 root, the tumor was removed en bloc. Postoperatively, the patient improved significantly gaining antigravity strength in both lower extremities. Conclusion The T10 dermatome is represented by the umbilical region. This referred pain may represent a mechanism by which a giant thoracic schwannoma may present as acute abdominal pain. Acute, intense abdominal pain with delayed neurologic deficit is a rare presentation of a thoracic schwannoma but should be considered as a possible cause of abdominal pain presenting without clear etiology. Although these lesions may be delayed in their diagnosis, early diagnosis and treatment may lead to an improved clinical outcome. PMID:19946504

    While open window thoracostomy (OWT) is a safe procedure and is indicated in patients who have thoracic empyema either with or without a bronchopleural fistula, it may prolong the hospital stay. We retrospectively analyzed the relationship between the etiology of thoracic empyema and the open window interval (OWI). Between January 1986 and May 1997, 53 patients resistant to conventional therapy underwent OWT for thoracic empyema at the Department of Surgery of the National Minami-Fukuoka Chest Hospital. The patients were classified into five groups based on the etiological findings of thoracic empyema. 44 patients also underwent closure of the window until June 1999. The average OWI was 180.4 +/- 51.9 (mean +/- SE) days for postoperative empyemas in lung cancer, 128.0 +/- 32.1 days for bacterial nontuberculous empyemas, 189.6 +/- 24.1 days for fungal empyemas, 365.8 +/- 201 days for empyemas caused by atypical mycobacteria and 322.0 +/- 58.7 days for tuberculous empyemas. There was no evidence that the OWI was related to either sex, age, etiology of thoracic empyemas, performance status, the existence of bronchopleural fistulae, complications of diabetes mellitus or preoperative malnutrition status in multivariable models. 5 patients underwent a second OWT because of recurrence of empyema. Mortality rate was 7.5%. There was no relationship between clinical factors including nutritional assessment and OWI. OWT generally is a safe and effective procedure for thoracic empyema resisting to conventional therapy except that it can make an extended hospital stay necessary. Copyright 2001 S. Karger AG, Basel

    Open surgery for thoracic aortic disease is associated with significant morbidity and the reported rates for paraplegia and stroke are 3%-19% and 6%-11%, respectively. Spinal cord ischemia and stroke have also been reported following endoluminal repair. This study reviews the incidence of paraplegia and stroke in a series of 186 patients treated with thoracic stent grafts. From July 1997 to September 2006, 186 patients (125 men) underwent endoluminal repair of thoracic aortic pathology. Mean age was 71 years (range, 17-90 years). One hundred twenty-eight patients were treated electively and 58 patients had urgent procedures. Anesthesia was epidural in 131, general in 50, and local in 5 patients. Seven patients developed paraplegia (3.8%; two urgent and five elective). All occurred in-hospital apart from one associated with severe hypotension after a myocardial infarction at 3 weeks. Four of these recovered with cerebrospinal fluid (CSF) drainage. One patient with paraplegia died and two had permanent neurological deficit. The rate of permanent paraplegia and death was 1.6%. There were seven strokes (3.8%; four urgent and three elective). Three patients made a complete recovery, one had permanent expressive dysphasia, and three died. The rate of permanent stroke and death was 2.1%. Endoluminal treatment of thoracic aortic disease is an attractive alternative to open surgery; however, there is still a risk of paraplegia and stroke. Permanent neurological deficits and death occurred in 3.7% of the patients in this series. We conclude that prompt recognition of paraplegia and immediate insertion of a CSF drain can be an effective way of recovering spinal cord function and improving the prognosis

    The authors reviewed CT scans and supine chest X-ray of 47 patients affected by severe thoracic trauma, examined in 1985-86. The sensibility of the two methodologies in the assessment of pneumothorax was compared. CT detected 25 pneumothorax, whereas supine chest X-ray allowed a diagnosis in 18 cases only. In 8 of the latter (44.4%) the diagnosis was made possible by the presence of indirect signs of pneumothorax only - the most frequent being the deep sulcus sign. The characterization of pneumothorax is important especially in the patients who need to be treated with mechanical ventilation therapy, or who are to undergo surgery in total anaesthesia

    We present our experience of total aortic arch replacement. Twenty-nine patients (21 males and 8 females; mean age 63.3 ± 13.3 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was non-dissecting aneurysm in 11 patients, including one aortitis and aortic dissection in 18 patients (acute type A: one, chronic type A: 11, chronic type B: six). Five patients had Marfan syndrome. In their previous operation, two patients had undergone the Bentall procedure, three had endovascular stenting, one had aortic root replacement with valve sparing and 12 had hemi-arch replacement for acute type A dissection. Approaches to the aneurysm were as follows: posterolateral thoracotomy with rib-cross incision in 16, posterolateral thoracotomy extended to the retroperitoneal abdominal aorta in seven, mid-sternotomy and left pleurotomy in three, anterolateral thoracotomy with partial lower sternotomy in two and clam-shell incision in one patient. Extension of aortic replacement was performed from the aortic root to the descending aorta in 4, from the ascending aorta to the descending aorta in 17 and from the ascending to the abdominal aorta in eight patients. Arterial inflow for cardiopulmonary bypass consisted of the femoral artery in 15 patients, ascending aorta and femoral artery in seven, descending or abdominal aorta in five and ascending aorta in two. Venous drainage site was the femoral vein in 10, pulmonary artery in eight, right atrium in five, femoral artery with right atrium/pulmonary artery in four and pulmonary artery with right atrium in two patients. The operative mortality, 30-day mortality and hospital mortality was one (cardiac arrest due to aneurysm rupture), one (rupture of infected aneurysm) and one (brain contusion), respectively. Late mortality occurred in three patients due to pneumonia, ruptured residual aneurysm and intracranial bleeding. Actuarial survival at 5 years after the operations was 80.6

    Although great progress has been achieved in thoracic organ transplantation through the development of effective immunosuppression, there is still significant risk of rejection during the early post-transplant period, creating a need for routine monitoring for both acute antibody and cellular mediated rejection. The currently available multiplexed, microbead assays utilizing solubilized HLA antigens afford the capability of sensitive detection and identification of HLA and non-HLA specific antibodies. These assays are being used to assess the relative strength of donor specific antibodies; to permit performance of virtual crossmatches which can reduce the waiting time to transplantation; to monitor antibody levels during desensitization; and for heart transplants to monitor antibodies post-transplant. For cell mediated immune responses, the recent development of gene expression profiling has allowed noninvasive monitoring of heart transplant recipients yielding predictive values for acute cellular rejection. T cell immune monitoring in heart and lung transplant recipients has allowed individual tailoring of immunosuppression, particularly to minimize risk of infection. While the current antibody and cellular laboratory techniques have enhanced the ability to manage thoracic organ transplant recipients, future developments from improved understanding of microchimerism and graft tolerance may allow more refined allograft monitoring techniques.

    Acute thoracic aortic dissection has a high mortality rate if untreated, so the diagnosis must be rapidly made. Multiple imaging techniques are often used. This retrospective study from 1988 to 1993 assesses the usefulness in diagnosis of chest X-rays, computed tomography (CT) scanning, aortography, magnetic resonance imaging (MRI), trans-thoracic (TTE) and trans-oesophageal (TOE) echocardiography. Forty-two patients with a final clinical diagnosis of dissection were studied. The diagnosis was confirmed in 16 (13 at surgery and three at autopsy). Three died with dissection given as the only cause of death. Chest X-ray abnormalities were seen in all 19 patients with surgery or death from dissection, with a widened mediastinum and/or dilated aorta being present in 17. In the group of 16 patients with surgery or autopsy proof, CT scans found dissections in 9 out of 12 patients studied and correctly classified the type in only five. Aortography was preformed in five, with accurate depiction of dissection and type in all. TTE found dissections in three of eight patients imaged by this method. MRI and TOE were preformed each on two patients, with accurate depiction of dissection and type in each. Because of the relatively low sensitivity of CT scanning in defining aortic dissections Westmead Hospital is currently assessing the use of TOE as the prime imaging modality prior to surgical intervention. 17 refs., 4 tabs., 4 figs

    Canada's contributions toward the 21st century's practice of thoracic surgery have been both unique and multilayered. Scattered throughout are tales of pioneers where none had gone before, where opportunities were greeted by creativity and where iconic figures followed one another. To describe the numerous and important achievements of Canadian thoracic surgeons in the areas of surgery for pulmonary tuberculosis, thoracic oncology, airway surgery and lung transplantation. Information was collected through reading of the numerous publications written by Canadian thoracic surgeons over the past 100 years, interviews with interested people from all thoracic surgery divisions across Canada and review of pertinent material form the archives of several Canadian hospitals and universities. Many of the developments occurred by chance. It was the early and specific focus on thoracic surgery, to the exclusion of cardiac and general surgery, that distinguishes the Canadian experience, a model that is now emerging everywhere. From lung transplantation in chimera twin calves to ex vivo organ preservation, from the removal of airways to tissue regeneration, and from intensive care research to complex science, Canadians have excelled in their commitment to research. Over the years, the influence of Canadian thoracic surgery on international practice has been significant. Canada spearheaded the development of thoracic surgery over the past 100 years to a greater degree than any other country. From research to education, from national infrastructures to the regionalization of local practices, it happened in Canada.

    Imaging of the thoracic duct is usually performed by radiological lymphography. However, this procedure, which uses an oil based dye injected directly into the lymph channels, has some adverse effects. In this paper we note that lymphoscintigraphy, a physiological and non invasive method, may visualize thoracic duct abnormalities, and might be particularly usefull when radiological lymphography is contraindicated.

    The aim of this study is to evaluate the feasibility and safety of robot-assisted thoracic surgery (RATS) lobectomy versus video-assisted thoracic surgery (VATS) for lobectomy in patients with non-small cell lung cancer (NSCLC). An electronic search of six electronic databases was performed to identify relevant comparative studies. Meta-analysis was performed by pooling the results of reported incidence of overall morbidity, mortality, prolonged air leak, arrhythmia, and pneumonia between RATS and VATS lobectomy. Subgroup analysis was also conducted based on matched and unmatched cohort studies, if possible. Relative risks (RR) with their 95% confidence intervals (CI) were calculated by means of Revman version 5.3. Twelve retrospective cohort studies were included, with a total of 60,959 patients. RATS lobectomy significantly reduced the mortality rate when compared with VATS lobectomy (RR = 0.54, 95% CI 0.38-0.77; P = 0.0006), but this was not consistent with the pooled result of six matched studies (RR = 0.12, 95% CI 0.01-1.07; P = 0.06). There was no significant difference in morbidity between the two approaches (RR = 0.97, 95% CI 0.85-1.12; P = 0.70). RATS lobectomy is a feasible and safe technique and can achieve an equivalent short-term surgical efficacy when compared with VATS, but its cost effectiveness also should be taken into consideration.

    Endovascular stent graft treatment of acute thoracic aortic transections is an encouraging minimally invasive alternative to open surgical repair. Between 2006 and 2008, 16 patients with acute thoracic aortic transections underwent evaluation at our institution. Seven patients who were treated with an endovascular stent graft were reviewed. The mean Glasgow Coma Score was 13.0, probability of survival was .89, and median injury severity score was 32. The mean number of intensive care unit days was 7.7, mean number of ventilator support days was 5.4, and hospital length of stay was 10 days. Mean blood loss was 285 mL, and operative time was 143 minutes. Overall mortality was 14%. Procedure complications were a bleeding arteriotomy site and an endoleak. Endovascular treatment of traumatic thoracic aortic transections appears to demonstrate superior results with respect to mortality, blood loss, operative time, paraplegia, and procedure-related complications when compared with open surgical repair literature.

    Full Text Available Background: A major challenge in the postoperative period is pain management which, if not adequately controlled, may contribute to patient discomfort and decreased patient satisfaction, and possibly increased morbidity and mortality. Both Thoracic paravertebral block and oblique subcostal transversus abdominis plane block can be used as analgesic techniques for abdominal surgeries. Our aim in this research was comparison of cumulative 24-h post-operative morphine consumption between ultrasound-guided oblique subcostal transversus abdominis plane block and ultrasound-guided thoracic paravertebral block in patients who underwent an open cholecystectomy under general anesthesia. Patients and methods: This study was performed on 46 patients who underwent open cholecystectomy under general anesthesia. All patients were randomly allocated alternatively to one of two equal groups to either undergo ultrasound-guided unilateral oblique subcostal transversus abdominis plane block Group (I or to undergo ultrasound-guided unilateral thoracic paravertebral block Group (II. Both groups were subjected to a similar analgesic regimen in the immediate post-operative period that involved intravenous patient-controlled morphine analgesia which was used in both groups. Results: The total morphine consumption in the first postoperative 24 h was lower in thoracic paravertebral block Group (II (9.9 mg in thoracic paravertebral block group vs. 15.4 mg in oblique subcostal transversus abdominis plane block Group (I with p < 0.001. The mean time of first request of analgesia in Group (I was 248.7 min compared to 432.1 for Group (II with p < 0.001. Conclusions: Both ultrasound-guided oblique subcostal transversus abdominis plain block and single injection ultrasound guided thoracic paravertebral block are effective analgesic techniques for upper abdominal surgeries and reduces postoperative opioid requirements. However, thoracic paravertebral block is more

    Studies have reported that thoracic CT may provide greater sensitivity compared with radiography in detection of pediatric rib fractures and fracture healing. The additional sensitivity afforded by thoracic CT may have medicolegal implications where abuse is suspected. To determine the additional value of postmortem thoracic CT compared with radiography in detecting pediatric rib fractures, and fracture healing, using autopsy findings as a gold standard. We retrospectively reviewed 56 coroner's cases with postmortem radiography and CT thoracic survey. All studies underwent primary interpretation by one or two radiologists. The study radiologist independently reviewed all images from 13 patients with positive findings on radiography, CT or autopsy. Sensitivity and specificity between observers and imaging modalities were compared. Primary interpretation: Fractures were recognized on radiography in 5/12 patients who had fractures found at autopsy, and on CT in 8/12 patients. In total, 29% (24/83) of fractures were reported on radiography, and 51% (52/101) of fractures were reported on CT. Study radiologist: Fractures were recognized on radiography in 7/12 patients who had fractures found at autopsy, and on CT in 11/12 patients. In total, 46% (38/83) of fractures were reported on radiography, and 85% (86/101) of fractures were reported on CT. Postmortem thoracic CT provides greater sensitivity than radiography in detecting pediatric rib fractures, most notably in anterior and posterior fractures. However, the degree of improvement in sensitivity provided by CT might depend on observer experience. (orig.)

    To evaluate the incidence and angiographic findings of the collateral pathway involving the internal thoracic artery in patients with chronic aortoiliac occlusive disease. Between March 2000 and Februrary 2001, 124 patients at our hospital underwent angiographic evaluation of chronic aortoiliac occlusive disease, and in 15 of these complete obstruction or severe stenosis of the aortoiliac artery was identified. The aortograms and collateral arteriograms obtained, including internal thoracic arteriograms, as well as the medical records of the patients involved, were evaluated. In nine patients there was complete occlusion of the infrarenal aorta, or diffuse stenosis of 75% or more in the descending thoracic aorta, and in the other six, a patent aorta but complete occlusion or stenosis of 75% or more of the common iliac artery was demonstrated. Collateral perfusion via hypertrophied internal thoracic arteries and rich anastomoses between the superior and inferior epigastric arteries, reconstituting the external iliac artery, were noted in all fifteen patients, regardless of symptom duration, which ranged from six months to twelve years. In patients with chronic aortoiliac occlusive disease, the internal thoracic artery, along with visceral collaterals and those from the contralateral side, is one of the major parietal collateral pathways

    2012-01-01

    Background and purpose: The incidence of retrosternal goiter (Rg) varies from 2% to 26% of all thyroidectomies, depending on the defining criteria . There are no clear guidelines to identify patients that require an intrathoracic approach. So, we tried to correlate, between the size and/ or anatomical site of the RSG based on preoperative CT findings and the surgical approaches used, aiming at defining those patients with RSG who are in need for thoracic approach. Patients and methods: Out of 1481 patients underwent thyroidectomy at the National Cancer Institute (NCI), Cairo University, between January 2000 and December 2009, only 73 (4.93%) of them had retrosternal extension. Demographic, clinical, operative, anatomical, and pathological data of patients with RSG were recorded and analyzed. Results: The intraoperative extension of the goiter correlated with the extension seen in the CT in all except two patients. Laterality and longitudinal extension found in preoperative CT, correlated well with the surgical findings. The approach used was cervical in 66 cases (90.4%); combined approach in six patients (8.2%). Pure thoracic (full sternotomy) was used alone in one case (1.4%). Extension of the RSG down to or below the arch was associated with an increased risk of using a thoracic approach p< 0.0001. Conclusion: Preoperative CT, can be used effectively to guide the indications for using a thoracic approach. Reaching the aortic arch or beyond and loss of fat planes in CT, recurrent and malignant disease, are significant risk factors for using a thoracic approach.

    Full Text Available High speed vehicles, drug abuse, alcohol and easy availability of handguns are the main reasons of increasing number of trauma especially thoracic trauma. Anaesthesiologist plays an important role in the management of extensive thoracic trauma. Thoracic trauma, penetrating or blunt, may cause damage to organs suspended in thorax viz. pleura, lungs, heart, great vessels, trachea and oesophagus. It may lead to pneumothorax, cardiac tamponade or life threatening haemorrhage. With aggressive care and management of these factors, majority of patients can survive and return to normal life.

    There is limited consensus on the optimal surgical strategy for double thoracic adolescent idiopathic scoliosis (AIS). Recent studies have reported that pedicle screw constructs to maximize scoliosis correction cause further thoracic spine lordosis. The objective of this study was to apply a new surgical technique for double thoracic AIS with rigid proximal thoracic (PT) curves and assess its clinical outcomes. Twenty one consecutive patients with Lenke 2 AIS and a rigid PT curve (Cobb angle ≥30º on side-bending radiographs, flexibility ≤30 %) treated with the simultaneous double-rod rotation technique (SDRRT) were included. In this technique, a temporary rod is placed at the concave side of the PT curve. Then, distraction force is applied to correct the PT curve, which reforms a sigmoid double thoracic curve into an approximate single thoracic curve. As a result, the PT curve is typically converted from an apex left to an apex right curve before applying the correction rod for PT and main thoracic curve. All patients were followed for at least 2 years (average 2.7 years). The average main thoracic and PT Cobb angle correction rate at the final follow-up was 74.7 and 58.0 %, respectively. The average preoperative T5-T12 thoracic kyphosis was 9.3°, which improved significantly to 19.0° (p corrected using SDRRT for Lenke 2 AIS with a rigid PT curve.

    Advantages of thoracic paravertebral analgesia (TPA) include placement of the catheter closer to the surgical field; however, the catheter can become damaged during the operation. We experienced a case of intraoperative TPA catheter breakage that prompted us to perform an experiment to investigate possible causes. A 50-year-old male underwent a thoracoscopic lower lobectomy under general anesthesia with TPA via an intercostal approach. Following surgery, it was discovered that the catheter had become occluded, as well as cut and fused, so we reopened the incision and removed the residual catheter. From that experience, we performed an experiment to examine electrocautery-induced damage in normal (Portex™, Smith's Medical), radiopaque (Perifix SoftTip™, BBraun), and reinforced (Perifix FX™, BBraun) epidural catheters (n = 8 each). Chicken meat was penetrated by each catheter and then cut by electrocautery. In the normal group, breakage occurred in 8 and occlusion in 6 of the catheters, and in the radiopaque group breakage occurred in 8 and occlusion in 7. In contrast, breakage occurred in only 3 and occlusion in none in the reinforced group, with the 5 without breakage remaining connected only by the spring coil. Furthermore, in 7 of the reinforced catheters, electric arc-induced thermal damage was observed at the tip of the catheter. A TPA catheter for thoracic surgery should be inserted via the median approach, or it should be inserted after surgery to avoid catheter damage during surgery.

Surgical treatment of thoracic aortic disease then progressed along with advances in surgical technique, conduit production, cardiopulmonary bypass, and endovascular technology. Despite radical advances in aortic surgery, principles established by surgical pioneers of the 19th century hold firm to this day. Copyright © 2017 Elsevier Inc. All rights reserved.

    Thoracic outlet syndrome is caused by compression of the neurovascular bundle as it passes from the upper thorax to the axilla. The neurovascular bundle can be compressed by bony structures such as the first rib, cervical ribs or bone tubercles, or from soft-tissue abnormalities like a fibrous band, muscle hypertrophy or space-occupying lesion. Thoracic outlet syndrome commonly affects young adults but can be seen in the pediatric age group, especially in older children. Diagnosis is based on a holistic approach encompassing clinical features, physical examination findings including those triggered by various maneuvers, electromyography, nerve conduction studies and imaging. Imaging is performed to confirm the diagnosis, exclude mimics and classify thoracic outlet syndrome into neurogenic, arterial, venous or mixed causes. MRI and MR angiography are useful in this process. A complete MRI examination for suspected thoracic outlet syndrome should include the assessment of anatomy and any abnormalities using routine sequences, vessel assessment with the arms in adduction by MR angiography and assessment of dynamic compression of vessels with abduction of the arms. The purpose of this paper is to describe the anatomy of the thoracic outlet, causes of thoracic outlet syndrome, the MR imaging techniques used in its diagnosis and the principles of image interpretation.

    To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD) and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs

    Radiologically guided drainage of 100 thoracic fluid collections is described in this paper. Collections that underwent drainage include empyemas, lung abscesses, bronchopleural fistulas (BPFs), mediastinal abscesses, paracardial collections, bronchogenic cysts, sequestrations, lymphoceles, lymphangiomas, malignant effusions, and necrotic tumors. Catheters were placed for sclerotherapy in nine patients. Guidance modalities (in descending order of frequency) were CT, US, fluoroscopy, and MR. Inadequate thoracostomy tube drainage occurred in a third of the patients prior to radiologic drainage. Drainages were effective in 85% of cases, sparing surgery or another thoracostomy tube. Complications occurred in 7% of patients, most being minor and none requiring operation. Criteria for drainage of lung abscess and BPF will be emphasized, as will techniques and methods of follow-up

    Simultaneous resection of hepatic and pulmonary metastases (HPM) from colorectal cancer (CRC) has been reported to be effective, but it is also considered invasive. We report the preliminary results of performing minimally invasive surgery using the open magnetic resonance (MR) imaging system to resect synchronous HPM from CRC in four patients. All four patients were referred for thoracoscopy-assisted interventional MR-guided microwave coagulation therapy (T-IVMR-MCT) combined with video-assisted thoracoscopic surgery (VATS). The median diameters of the HPM were 18.2 and 23.2 mm, respectively. The median duration of VATS and T-IVMR-MCT was 82.5 and 139 min, respectively. All patients were discharged without any major postoperative complications. One patient was still free of disease at 24 months and the others died of disease progression 13, 36, and 47 months without evidence of recurrence in the treated area. Thus, simultaneous VATS + T-IVMR-MCT appears to be an effective option as a minimally invasive treatment for synchronous HPM from CRC.

    Spontaneous spinal CSF leaks are an important cause of new-onset headaches. Such leaks are reported to be particularly common at the cervico-thoracic junction. The authors undertook a study to determine the significance of these cervico-thoracic CSF leaks. The patient population consisted of a consecutive group of 13 patients who underwent surgery for CSF leak repair based on CT myelography showing CSF extravasation at the cervico-thoracic junction but without any evidence of an underlying structural lesion. The mean age of the 9 women and 4 men was 41.2 years. Extensive extrathecal longitudinal CSF collections were demonstrated in 11 patients. At surgery, small leaking arachnoid cysts were found in 2 patients. In the remaining 11 patients, no clear source of CSF leakage could be identified at surgery. Resolution of symptoms was achieved in both patients with leaking arachnoid cysts, but in only 3 of the 11 patients with negative intraoperative findings. Postoperative spinal imaging was performed in 9 of the 11 patients with negative intraoperative findings and showed persistence of the longitudinal intraspinal extradural CSF. Further imaging revealed the site of the CSF leak to be ventral to the thoracic spinal cord. Five of these patients underwent microsurgical repair of the ventral CSF leak with resolution of symptoms in all 5 patients. Cervico-thoracic extravasation of dye on myelography does not necessarily indicate the site of the CSF leak. Treatment directed at this site should not be expected to have a high probability of sustained improvement of symptoms. © 2015 American Academy of Neurology.

    To report approach, technical success, safety, and short-term outcomes of thoracic duct stent-graft reconstruction for the treatment of chylothorax. Two patients, 1 (50%) male and 1 (50%) female, with mean age of 38 years (range: 16-59 years) underwent endolymphatic thoracic duct stent-graft reconstruction between September 2016 and July 2017. Patients had radiographic left-sided chylothoraces (n = 2) from idiopathic causes (n = 1) and heart transplantation (n = 1). In both (100%) patients, antegrade lymphatic access was used to opacify the thoracic duct after which retrograde access was used for thoracic duct stent-graft placement. Pelvic lymphangiography technical success, antegrade cisterna chyli cannulation technical success, thoracic duct opacification technical success, retrograde thoracic duct access technical success, thoracic duct stent-graft reconstruction technical success, ethiodized oil volume, contrast volume, estimated blood loss, procedure time, fluoroscopy time, radiation dose, clinical success, complications, deaths, and follow-up were recorded. Pelvic lymphangiography, antegrade cisterna chyli cannulation, thoracic duct opacification, retrograde thoracic duct access, and thoracic duct stent-graft reconstruction were technically successful in both (100%) patients. Mean ethiodized oil volume was 8 mL (range: 5-10 mL). Mean contrast volume was 13 mL (range: 5-20 mL). Mean estimated blood loss was 13 mL (range: 10-15 mL). Mean fluoroscopy time was 50.4 min (range: 31.2-69.7 min). Mean dose area product and reference air kerma were 954.4 μGmy 2 (range: 701-1,208 μGmy 2 ) and 83.5 mGy (range: 59-108 mGy), respectively. Chylothorax resolved in both (100%) patients. There were no minor or major complications directly related to the procedure. Thoracic duct stent-graft reconstruction may be a technically successful and safe alternative to thoracic duct embolization, disruption, and surgical ligation for the treatment of chylothorax

    The objective of this study was to evaluate the efficacy of lung cancer screening by thoracic computed tomography (CT), a randomized controlled trial was planned in Japan. The randomized trial was designed as follows: participants were randomly assigned into 2 groups, CT group and XP group; XP group would receive 10 times of lung cancer screening by chest x-ray annually for 10 years; smokers in CT group would receive 10 times of lung cancer screening by thoracic CT annually for 10 years; non-smokers in CT group would receive 3 times of lung cancer screening by thoracic CT and 7 times of chest x-ray during 10 years. A pilot study was performed to evaluate the feasibility of the trial. A letter for recruitment to participate in the above trial was mailed to the citizens in Hakui City, who were 50-64 years old and underwent regular lung cancer screening using chest x-ray this year. In the letter we explained that the efficacy of lung cancer screening by thoracic CT had not been proved yet; only half of the participants could undergo thoracic CT screening; thoracic CT screening might cause unfavorable consequences like radiation exposure, false positives or overdiagnosis. Of 329 persons who received the letter of recruitment, 117 replied. After meeting with us for detailed explanation, 111 persons participated in the above randomized trial. The compliance of recruitment is high (approximately one third) and the above trial may be feasible. (author)

    Full Text Available OBJECTIVE: To evaluate early and mid-term results in patients undergoing proximal thoracic aortic redo surgery. METHODS: We analyzed 60 patients (median age 60 years, median logistic EuroSCORE 40 who underwent proximal thoracic aortic redo surgery between January 2005 and April 2012. Outcome and risk factors were analyzed. RESULTS: In hospital mortality was 13%, perioperative neurologic injury was 7%. Fifty percent of patients underwent redo surgery in an urgent or emergency setting. In 65%, partial or total arch replacement with or without conventional or frozen elephant trunk extension was performed. The preoperative logistic EuroSCORE I confirmed to be a reliable predictor of adverse outcome- (ROC 0.786, 95%CI 0.64-0.93 as did the new EuroSCORE II model: ROC 0.882 95%CI 0.78-0.98. Extensive individual logistic EuroSCORE I levels more than 67 showed an OR of 7.01, 95%CI 1.43-34.27. A EuroSCORE II larger than 28 showed an OR of 4.44 (95%CI 1.4-14.06. Multivariate logistic regression analysis identified a critical preoperative state (OR 7.96, 95%CI 1.51-38.79 but not advanced age (OR 2.46, 95%CI 0.48-12.66 as the strongest independent predictor of in-hospital mortality. Median follow-up was 23 months (1-52 months. One year and five year actuarial survival rates were 83% and 69% respectively. Freedom from reoperation during follow-up was 100%. CONCLUSIONS: Despite a substantial early attrition rate in patients presenting with a critical preoperative state, proximal thoracic aortic redo surgery provides excellent early and mid-term results. Higher EuroSCORE I and II levels and a critical preoperative state but not advanced age are independent predictors of in-hospital mortality. As a consequence, age alone should no longer be regarded as a contraindication for surgical treatment in this particular group of patients.

    Objectives Emergency thoracic surgery in the elderly represents an extreme situation for both the surgeon and patient. The lack of an adequate patient history as well as the inability to optimize any co-morbidities, which are the result of the emergent situation, are the cause of increased morbidity and mortality. We evaluated the outcome and prognostic factors for this selected group of patients. Design Retrospective chart review. Setting Academic tertiary care referral center. Participants Emergency patients treated at the Department of Thoracic Surgery, University Hospital of Luebeck, Germany. Main outcome measures Co-morbidities, mortality, risk factors and hospital length of stay. Results A total of 124 thoracic procedures were performed on 114 patients. There were 79 men and 36 women (average age 72.5 ±6.4 years, range 65–94). The overall operative mortality was 25.4%. The most frequent indication was thoracic/mediastinal infection, followed by peri- or postoperative thoracic complications. Risk factors for hospital mortality were a high ASA score, pre-existing diabetes mellitus and renal insufficiency. Conclusions Our study documents a perioperative mortality rate of 25% in patients over 65 who required emergency thoracic surgery. The main indication for a surgical intervention was sepsis with a thoracic/mediastinal focus. Co-morbidities and the resulting perioperative complications were found to have a significant effect on both inpatient length of stay and outcome. Long-term systemic co-morbidities such as diabetes mellitus are difficult to equalize with respect to certain organ dysfunctions and significantly increase mortality. PMID:21369531

    The aim of this retrospective study was to investigate the use of thoracic Computed Tomography (CT) in the Emergency Department of a Dublin Academic Teaching Hospital over a six month period. Data was retrieved using the hospital\\'s computerised information system. There were 202 referrals in total for thoracic CT from the Emergency Department during this time period. The most common indication for thoracic CT referral was for the investigation of pulmonary embolism with 127 (63%) referrals. There were 40 (25%) referrals for suspected malignancy and lung disease, whilst 8 (4%) of the referrals were for investigation of thoracic aortic dissection, 8 (4%) for infection, and 6 (3%) were for investigation of thoracic injury. Only 8 (4%) of all referrals were for investigation of injury as a result of chest trauma.

    Thoracic surgeons participating in this survey seemed to have clearly indicated their perception of VATS major lung resections, in particular VATS lobectomy. 1. The acronym VATS as a short form of "video-assisted thoracic surgery" was the preferred terminology. 2. According to the respondents, the need or use of rib spreading served as the defining characteristic of "open" thoracic surgery. 3. It was most commonly suggested that VATS lobectomy is performed by means of two or three port incisions with the addition of a minithoracotomy or access incision. 4. Rib spreading (shearing) was not deemed acceptable as part of a strictly defined VATS procedure. 5. Although there was no general consensus, respondents suggested that the preferred approach for visualization in a VATS procedure was only through the video monitor. 6. Although minimally invasive procedures for lung resection are still mainly being used for diagnostic and minor therapeutic purposes, young surgeons seemed to be more likely to recommend VATS lung surgery for major pulmonary resections than their more senior colleagues. 7. The survey confirmed that the use of the standard posterolateral thoracotomy is still widespread. Almost 40% of the surgeons claimed to use the standard posterolateral thoracotomy for more than 50% of their cases and less than 30% use it for less than 5% of cases. 8. The major reasons to perform VATS lobectomy were perceived to be reduced pain and decreased hospitalization. 9. Approximately 60% of the surgeons claimed to perform VATS lobectomy in less than 5% of their lobectomy cases. Younger consultants reported using VATS lobectomy in up to 50% of their lobectomy cases. There was the suggestion that lack of resources could justify the minor impact of VATS lobectomy in the thoracic surgical practice in middle- to low-income countries. 10. The currently available scientific evidence on safety and effectiveness, and technologic advancements were emphasized as the two factors having a

    We sought to define an accurate measure of thoracic surgical education costs. Program directors from six distinct and differently sized and geographically located thoracic surgical training programs used a common template to provide estimates of resident educational costs. These data were reviewed, clarifying questions or discrepancies when noted and using best estimates when exact data were unavailable. Subsequently, a composite of previously published cost-estimation products was used to capture accurate cost data. Data were then compiled and averaged to provide an accurate picture of all costs associated with thoracic surgical education. Before formal accounting was performed, the estimated average for all programs was approximately $250,000 per year per resident. However, when formal evaluations by the six programs were performed, the annual cost of resident education ranged from $330,000 to $667,000 per year per resident. The average cost of $483,000 per year was almost double the initial estimates. Variability was noted by region and size of program. Faculty teaching costs varied from $208,000 to $346,000 per year. Simulation costs ranged from $0 to $80,000 per year. Resident savings to program ranged from $0 to $135,000 per year and averaged $37,000 per year per resident. Thoracic surgical education costs are considerably higher than initial estimates from program directors and probably represent an unappreciated source of financial burden for cardiothoracic surgical educational programs.

    1998-01-01

    Purpose: To describe and discuss the thoracic CT features of hypovolemic shock. Material and Methods: From a group of 18 patients with signs of hypovolemia on contrast-enhanced abdominal CT, 11 were selected for our study as having also undergone a complete chest examination. Pulse rate, blood pressure, trauma score value, Glasgow coma scale value, surgical result, and final outcome were retrospectively evaluated. The CT features analyzed were: decreased cardiac volume, reduced caliber of the thoracic aorta, aortic branches and caval venous system, increased enhancement of the aorta, and increased enhancement of the pulmonary collapses/contusions. Results: All 11 subjects presented severe injuries and hemodynamic instability; 7 were stable enough to undergo surgery; only 1 of the 11 survived. Two patients showed none of the features of thoracic hypovolemia. All the other patients presented at least two signs: reduced caliber of the thoracic aorta in 7 cases; decreased volume of the cardiac chambers and increased aortic enhancement in 6; decreased caliber of the aortic vessels in 4; decreased caliber of the caval veins in 3; and increased enhancement of the pulmonary collapses/contusions in 3. Conclusions: In patients with hypovolemia, CT may show several thoracic findings in addition to abdominal ones. Knowledge of these features is important for distinguishing them from traumatic injuries. (orig.)

    To evaluate the efficacy and safety of extended-field radiation therapy for patients with thoracic superficial esophageal cancer (SEC). From May 2007 to October 2016, a total of 24 patients with thoracic SEC (T1a and T1b) who underwent definitive radiotherapy and were analyzed retrospectively. The median total radiotherapy dose was 64 Gy (range, 54 to 66 Gy) in conventional fractionation. All 24 patients received radiotherapy to whole thoracic esophagus and 23 patients received elective nodal irradiation. The supraclavicular lymph nodes, the celiac lymph nodes, and both of those nodal areas were included in 11, 3, and 9 patients, respectively. The median follow-up duration was 28.7 months (range 7.9 to 108.0 months). The 3-year overall survival, local control, and progression-free survival rates were 95.2%, 89.7%, and 78.7%, respectively. There were 5 patients (20.8%) with progression of disease, 2 local failures (8.3%) and 3 (12.5%) regional failures. Three patients also experienced distant metastasis and had died of disease progression. There were no treatment-related toxicities of grade 3 or higher. Definitive extended-field radiotherapy for thoracic SEC showed durable disease control rates in medically inoperable and endoscopically unfit patients. Even extended-field radiotherapy with elective nodal irradiation was safe without grade 3 or 4 toxicities.

    To evaluate the feasibility of MRI for static and dynamic assessment of the deployment of thoracic aortic stent grafts after emergency implantation in trauma patients. Twenty patients initially presenting with a rupture of the thoracic aorta were enrolled in this study. All patients underwent thoracic endovascular aortic repair (TEVAR). The deployment of the implanted stent graft was assessed by CTA and MRI, comprising the assessment of the aortic arch with and without contrast agent, and the assessment of the motion of the stent graft over the cardiac cycle. The stent graft geometry and motion over the cardiac cycle were assessable by MRI in all patients. Flow-mediated signal variations in areas of flow acceleration could be well visualised. No statistically significant differences in stent-graft diameters were observed between CT and MRI measurements. MRI appears to be a valuable tool for the assessment of thoracic stent grafts. It shows similar performance in the accurate assessment of stent-graft dimensions to the current gold standard CTA. Its capability of providing additional functional information and the lack of ionising radiation and nephrotoxic contrast agents may make MRI a valuable tool for monitoring patients after TEVAR.

    The aim of this study was to assess the preoperative nutritional status of patients undergoing thoracic surgery using different nutritional tools. . We conducted a prospective study on a sample of 43 thoracic patients, including 23 with neoplasms and 20 with non-neoplastic pathology who underwent thoracic surgery procedures between July-September 2011, in the Thoracic Surgery Clinic in Iaşi. Weight and height were measured and body mass index (BMI) was calculated. WHO classification for BMI categories was used. Preoperative serum level of transthyretin (TTR) and demographic data (gender, age) were also assessed. All patients were examined by the Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002). After performing SGA, 67.9% of the patients were well-nourished, 21.4% were moderately or suspected of being malnourished and 10.7% were severely malnourished. The level of TTR was significantly lower in the moderately or severely malnourished group, compared to those considered well-nourished. According to NRS-2002, 42.9% of the patients were considered at nutritional risk. The level of TTR of these patients was lower than the level of TTR of the patients without nutritional risk, but without statistical significance. Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002) are useful in identifying patients with nutritional risk, so that appropriate nutritional management could be initialised even before surgery.

  2. Successful Management of a Combined Abdominal and Thoracic Trauma with Rectal Impalement: Report of a Case

    Directory of Open Access Journals (Sweden)

    Konstantinos Kasapas

    2013-01-01

    Full Text Available Introduction. Combined abdominal and thoracic impalement injuries are a rare form of penetrating trauma. Nowadays, they occur more frequently as an accident and not so often as a deliberate violent action. Case Report. A 35-year-old man was admitted to our emergency department with chest pain and respiratory distress after he had reportedly slipped in his bathtub. Abdominal and thoracic imaging, including computed tomography (CT, confirmed a right-sided pneumothorax and a liver laceration without bleeding or further endoperitoneal trauma. A chest tube was placed. During his hospitalization in the first 24-hour period, he complained of abdominal and right shoulder pain accompanied by fever. A new abdominal and thoracic CT scanning revealed a rupture of the rectosigmoid, a rupture of right hemidiaphragm, and a foreign body in the thoracic cavity. The patient admitted that a broomstick was violently placed through his rectum, and he underwent a thoracotomy with an exploratory laparotomy. The foreign object was removed, the diaphragmatic rupture was repaired, and a Hartmann’s procedure was performed. The postoperative course was uneventful. Conclusion. In cases of combined thoracoabdominal trauma, high index of suspicion is required when medical history is misleading and the injuries are not obvious immediately. A coordinated team effort in a well-organized trauma center is also very important.

    2011-06-01

    We report our experience in starting a robotic program in thoracic surgery. We retrospectively reviewed our experience in starting a robotic program in general thoracic surgery on a consecutive series of patients. Between February 2009 and September 2010, 150 patients underwent robotic operations. Types of procedures were lobectomy in 62, thymectomy in 30, and benign esophageal procedures in 6. No thymectomy or esophageal procedures required conversion. One conversion was needed for suspected bleeding for a mediastinal mass. Twelve patients were converted for lobectomy (none for bleeding, 1 in the last 24). Median operative time for robotic thymectomy was 119 minutes, and median length of stay was 1 day. The median time for robotic lobectomy was 185 minutes, and median length of stay was 2 days. There were no operative deaths. Morbidity occurred in 23 patients (15%). All patients with cancer had R0 resections and resection of all visible mediastinal and hilar lymph nodes. Robotic surgery is safe and oncologically sound. It requires training of the entire operating room team. The learning curve is steep, involving port placement, availability of the proper instrumentation, use of the correct robotic arms, and proper patient positioning. The robot provides an ideal surgical approach for thymectomy and other mediastinal tumors. Its advantage over thoracoscopy for pulmonary resection is unproven; however, we believe complete thoracic lymph node dissection and teaching is easier. Importantly, defined credentialing for surgeons and cost analysis studies are needed. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    2017-10-01

    Background  Congenital diaphragmatic hernia (CDH) is fatal in severe cases of pulmonary hypoplasia. We experienced a fatal case of pulmonary hypoplasia due to CDH, thoracic myelomeningocele (MMC), and thoracic dysplasia. This constellation of anomalies has not been previously reported. Case Report  A male infant with a prenatal diagnosis of thoracic MMC with severe hydrocephalus and scoliosis was born at 36 weeks of gestation. CDH was found after birth and the patient died of respiratory failure due to pulmonary hypoplasia and persistent pulmonary hypertension of the newborn at 30 hours of age despite neonatal intensive care. An autopsy revealed a left CDH without herniation of the liver or stomach into the thoracic cavity, severe hydrocephalus, Chiari malformation type II, MMC with spina bifida from Th4 to Th12, hemivertebrae, fused ribs, deformities of the thoracic cage and legs, short trunk, and agenesis of the left kidney. Conclusion  We speculate that two factors may be associated with the severe pulmonary hypoplasia: decreased thoracic space due to the herniation of visceral organs caused by CDH and thoracic dysplasia due to skeletal deformity and severe scoliosis.

    Uniport video-assisted thoracoscopic surgery (VATS) has emerged as a less invasive approach for the treatment of non-small cell lung cancer (NSCLC). However, whether uniport VATS has more potential advantages over multiport VATS remains controversial. This meta-analysis aimed to compare the perioperative efficacy of uniport and multiport VATS for T1-3N0M0 NSCLC. An electronic and manual search of literature published before 1st October 2017 was conducted using PubMed, Embase, Web of Science, and the Wiley Online library. The effective values of dichotomous variables or continuous variables were estimated by odds ratios (OR) or by standardized mean differences (SMD) with 95% confidence intervals (CIs) respectively. Eleven relevant observational studies were included for meta-analysis. Results demonstrated that patients in the uniport group had a significant reduction in the duration of postoperative drainage (uniport: 4.39±2.48 vs. multiport: 4.99±3.24 days; P=0.003), bleeding volume (97.7±60.0 vs. 116.7±99.7 mL; P=0.006), length of hospital stay (6.3±2.4 vs. 7.0±3.6 days; Prate of complications (14.5% vs. 17.5%; P=0.008). There were no significant differences between the two treatment groups with regards to mortality, operative time, the number of dissected lymph nodes or the conversion rate. Uniport VATS might have represent a preferable option for the treatment of T1-3N0M0 NSCLC, due to its superior perioperative efficacy.

    Purpose: Minimally invasive techniques like video-assisted thoracoscopic surgery (VATS) are currently the method of choice for the resection of small pulmonary nodules, when they are located in the periphery of the lungs. To guarantee quick and safe intraoperative identification of the nodule, preoperative marking is necessary and sensible. We report about our experiences in 184 markings with a special lung marking wire, which is placed in or around the pulmonary nodule using CT guidance. Materials and Methods: In 184 patients (97 m, 87f, mean age: 58.1 {+-} 13.7 years) with pulmonary nodules, scheduled for resection with VATS, a special lung marking wire was placed preoperatively under CT guidance. We evaluated the technical success, safety, necessity of conversion to thoracotomy and histology in all patients. Results: The marking wire could be positioned successfully in 181 cases (98.4 %). There was one major complication (uncontrollable pneumothorax). Minor adverse events like small pneumothorax (53.3 %) or a perifocal bleeding (30.4 %) did not necessitate treatment. Complete resection of the marked nodule was successful in 98.4 % of the patients. Conversion to thoracotomy was necessary in 29 patients (15.9 %) due to bleeding, adhesions, malignancy or wire dislocation. Histology revealed a benign nodule in 96 cases (54.4 %) and a malignant lesion in 78 cases (45.6 %), of which only 21 nodules (11.5 %) turned out to present a primary pulmonary carcinoma. Conclusion: CT-guided marking of pulmonary nodules using a special marking wire followed by thoracoscopic resection is an efficient and safe method for diagnosing suspicious nodules in the periphery of the lung.

    Full Text Available PRESENTATION OF CASE Actinomycetes are branching gram-positive anaerobic bacteria belonging to Actinomycetaceae family and are commensals in human oropharynx, gastrointestinal tract and female genitalia. Thoracic or pulmonary actinomycosis is an uncommon bacterial infection. The diagnosis of pulmonary or thoracic actinomycosis is often confounding because of its shared clinical features with malignant lung diseases and chronic suppurative lung diseases. However, chest physicians should be aware of actinomycosis being a differential diagnosis in persistent shadows in lung as early diagnosis leads to good prognosis. 1

    Full Text Available Background/Aim. Thoracic drainage is a surgical procedure for introducing a drain into the pleural space to drain its contents. Using this method, the pleura is discharged and set to the physiological state which enables the reexpansion of the lungs. The aim of the study was to prove that the use of modern principles and protocols of thoracic drainage significantly reduces the occurrence of failures and complications, rendering the treatment more efficient. Methods. The study included 967 patients treated by thoracic drainage within the period from January 1, 1989 to June 1, 2000. The studied patients were divided into 2 groups: group A of 463 patients treated in the period from January 1, 1989 to December 31, 1994 in whom 386 pleural drainage (83.36% were performed, and group B of 602 patients treated form January 1, 1995 to June 1, 2000 in whom 581 pleural drainage (96.51% were performed. The patients of the group A were drained using the classical standards of thoracic drainage by the general surgeons. The patients of the group B, however, were drained using the modern standards of thoracic drainage by the thoracic surgeons, and the general surgeons trained for this kind of the surgery. Results. The study showed that better results were achieved in the treatment of the patients from the group B. The total incidence of the failures and complications of thoracic drainage decreased from 36.52% (group A to 12.73% (group B. The mean length of hospitalization of the patients without complications in the group A was 19.5 days versus 10 days in the group B. The mean length of the treatment of the patients with failures and complications of the drainage in the group A was 33.5 days versus 17.5 days in the group B. Conclusion. The shorter length of hospitalization and the lower morbidity of the studied patients were considered to be the result of the correct treatment using modern principles of thoracic drainage, a suitable surgical technique, and a

    This case study describes the process of examination, re-examination, and intervention for a collegiate runner with mechanical thoracic pain preventing athletic participation and limiting daily function. Unimpaired function fully returned in less than 3 weeks with biweekly sessions to re-establish normal and painfree thoracic mechanics via postural hygiene, exercise, mobilization, and manipulation. The outcome of this case study supports the original hypothesis that the pattern of impairments was in fact responsible for the functional limitations and disability in this athlete. At the time of publication the athlete was without functional limitations and had fully returned to competitive sprinting for the university track team.

    Full Text Available Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

    Treating thoracic infective spondylodiscitis with anterior surgical approaches carry a relatively high risk of perioperative and postoperative complications. Posterior approaches have been reported to result in lower complication rates than anterior procedures, but more evidence is needed to demonstrate the safety and efficacy of 1-stage posterior approaches for treating infectious thoracic spondylodiscitis.Preoperative and postoperative clinical data, of 18 patients who underwent 2 types of 1-stage posterior procedures, costotransversectomy and transforaminal thoracic interbody debridement and fusion and 7 patients who underwent anterior debridement and reconstruction with posterior instrumentation, were retrospectively assessed.The clinical outcomes of patients treated with 1-stage posterior approaches were generally good, with good infection control, back pain relief, kyphotic angle correction, and either partial or solid union for fusion status. Furthermore, they achieved shorter surgical time, fewer postoperative complications, and shorter hospital stay than the patients underwent anterior debridement with posterior instrumentation.The results suggested that treating thoracic spondylodiscitis with a single-stage posterior approach might prevent postoperative complications and avoid respiratory problems associated with anterior approaches. Single-stage posterior approaches would be recommended for thoracic spine infection, especially for patients with medical comorbidities.

  13. Postoperative thoracic hemorrhage after right upper lobectomy with thoracic wall resection during rivaroxaban anticoagulant therapy for deep leg vein thrombosis: A case report

    Full Text Available Introduction: Postoperative pulmonary embolism (PE is the one of the most important complications after thoracic surgery. This complicatin after the surgery is often treated by new anticoaglant drug, such as rivaroxaban, which dose not need to the monitoring of blood coaglation system. We experienced postoperative bleeding case during anticoaglant therapy using rivaroxaban. Presentation of case: The patient underwent a right upper lobectomy with lung and chest wall resection for lung cancer. On postoperative day (POD 10, we started to use rivaroxaban to treat the deep vein thrombosis (DVT. Four days after starting the rivaroxaban treatment, severe surgical site hemorrhage occurred, which led to the need for the infusion of concentrated red cells (CRC. After stopping the rivaroxaban, the thoracic bleeding ceased. Because the event occurred so long after the surgery, and because the bleeding stopped after withdrawal of treatment, we believe that rivaroxaban induced the thoracic bleeding. Conclusion: Some reports in the field of orthopedics (Turpie et al., 2009 have noted that rivarxaban is effective to prevent postoperative DVT. However, there were few reports that invied the attention to postoperative bleeding be induced by rivarxaban. Thus, we describe this case in order to alert clinicians to the potential bleeding risks associated with the admistration of rivaroxaban postoperatively.

    2016-01-01

    Full Text Available The sympathetic block is widely used for treating neuropathic pain such as complex regional pain syndrome (CRPS. However, single sympathetic block often provides only short-term effect. Moreover, frequent procedures for sympathetic block may increase the risk of complications. The use of epidural route may be limited by concern of infection in case of previous implantation of the spinal cord stimulation (SCS. In contrast, a continuous sympathetic block can be administered without such concerns. The continuous thoracic sympathetic block (TSGB has been used to treat the ischemic disease and other neuropathic conditions such as postherpetic neuralgia. We administered continuous thoracic sympathetic block using catheter in CRPS patients who underwent SCS implantations and achieved desirable outcomes. We believe a continuous sympathetic block is a considerable option before performing neurolysis or radiofrequency rhizotomy and even after SCS implantation.

    2017-08-01

    Full Text Available Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications. Further, the effectiveness and modality of prolonged antibiotic prophylaxis and/or preoperative respiratory physiotherapy should be assessed in such cases.

    Twenty patients with fractures of the thoracic and lumbar spine underwent computed tomography (CT) following Harrington distraction instrumentation and a spinal fusion. CT was done to search for a cause of persistent cord or nerve root compression in those patients who failed to improve and completely recover their partial neurologic deficit (14 cases). The most common abnormality was the presence of residual bone fragments originating in the burst fracture of a vertebral body displaced posteriorly, into the spinal canal. In patients with complications in the late recovery period, CT found exuberant callus indenting the canal or lack of fusion of the bone grafts placed in the anterolateral aspect of the vertebral bodies. This experience indicates that CT is the modality of choice for spinal canal evaluation in those patients who fail to have an optimal clinical course following fractures of the thoracic and lumbar spine treated with Harrington rods

    To determine the presentation and management outcome of thoracic trauma in a tertiary care setting. A total of 143 patients, who presented with chest trauma, were included in the study. All the patients were assessed by the history, physical examination and ancillary investigations. Appropriate managements were instituted as required. Data was described in percentages. out of 143 patients, 119 (83)% were males and 24 (17)% were females. Most of the patients belonged to the age group of 21-50 years. Ninety seven (66)% patients were admitted for indoor management. Blunt injury was found in 125 (87.4%) patients, while penetrating injuries in only 18 (12.6%) patients. Road Traffic Accidents (RTAs) were the commonest cause of trauma (n=103, 72%). Rib fracture was the commonest chest injury (74% patients). Head injury was the most frequently associated injury (18% of the patients). Tube thoracostomy was the commonest intervention undertaken in 65 (45%) patients. Seventeen (11.88%) patients were managed with mechanical ventilation. there were 17 deaths with a mortality rate of 11.88%. Thoracic trauma is an important cause of hospitalization, morbidity and mortality in the younger population. RTAs constitute the leading cause of thoracic trauma in our setup. Tube thoracostomy is the most frequent and at times the only invasive procedure required as a definitive measure in thoracic trauma patients. A policy of selective hospitalization helps to avoid unnecessary hospital admissions. (author)

    From 1994 to 1995, to evaluate the utility of preoperative CT, EUS (endoscopic ultrasonography) and US in the diagnosis of lymph node metastasis in thoracic esophageal cancer, 94 patients with thoracic esophageal cancer who underwent esophagectomy were studied clinicopathologically. The sensitivity of EUS diagnosis of upper mediastinal lymph node metastasis (85%), left-sided paragastrin lymph node metastasis (73-77%), and especially lower paraesophageal lymph node metastasis (100%) were good. But due to their low-grade specificity in EUS diagnosis, their overall accuracy was not very good. On the other hand, the overall accuracy of the CT diagnosis of lymph node metastasis was fine. However, sensitivity, the most important clinical factor in the CT diagnosis of lymph node metastasis was considerably inferior to EUS. The assessment of the diagnosis of lymph node metastasis around the tracheal bifurcation and the pulmonary hilum and the left para-cardial lesion by CT or EUS was poor. It was concluded that lymph node metastasis of these area must be the pitfall in preoperative diagnosis. The average diameter of the lymph nodes and the proportion of cancerous tissue in the lymph nodes diagnosed as metastatic lymph nodes by CT was larger than that of the false negative lymph nodes. However, the lymph nodes diagnosed as true positives by EUS showed no such tendency. This must be the reason the sensitivity of the EUS diagnosis and specificity of the CT diagnosis were favorable, but the specificity of the EUS diagnosis and especially the sensitivity of the CT diagnosis were not as good.

    2010-01-01

    Endovascular treatment is an established therapy for thoracic aortic disease. Collapse of the endograft is a potentially fatal complication. We reviewed 16 patients with a thoracic endograft between 2001 and 2006. Medical records of the treated patients were studied. Data collected include age, gender, diagnosis, indication for endoluminal treatment, type of endograft, and time of follow up. All patients (n = 16; mean age, 61 years; range, 21-82 years) underwent computed tomography (CT) for location of the lesion and planning of the intervention. Time of follow-up with CT scan ranged from 1 to 61 months. Indications for endovascular treatment were degenerative aneurysm (n = 7; 44%), aortic dissection (n = 2; 12%), perforated aortic ulcer (n = 4; 25%), and traumatic aortic injury (n = 3; 19%). Three patients suffered from a collapse of the endograft (one patient distal, two patients proximal) between 3 and 8 days after endovascular treatment. These patients were younger (mean age, 37 ± 25 years vs. 67 ± 16 years; P 0.05]; distal, 45 ± 23.5% vs. 38 ± 21.7% [P > 0.05]). Proximal collapse was corrected by placing a bare stent. In conclusion, risk factors for stent-graft collapse are a small lumen of the aorta and a small radius of the aortic arch curvature (young patients), as well as oversizing, which is an important risk factor and is described for different types of endografts and protheses (Gore TAG and Cook Zenith). Dilatation of the collapsed stent-graft is not sufficient. Following therapy implantation of a second stent or surgery is necessary in patients with a proximal endograft collapse. Distal endograft collapse can possibly be treated conservatively under close follow-up.

    Thoracic fat has been associated with an increased risk of coronary artery disease (CAD). As endothelium-dependent vasoreactivity is a surrogate of cardiovascular events and is impaired early in atherosclerosis, we aimed at assessing the possible relationship between thoracic fat volume (TFV) and endothelium-dependent coronary vasomotion. Fifty healthy volunteers without known CAD or major cardiovascular risk factors (CRFs) prospectively underwent a {sup 82}Rb cardiac PET/CT to quantify myocardial blood flow (MBF) at rest, and MBF response to cold pressor testing (CPT-MBF) and adenosine (i.e., stress-MBF). TFV was measured by a 2D volumetric CT method and common laboratory blood tests (glucose and insulin levels, HOMA-IR, cholesterol, triglyceride, hsCRP) were performed. Relationships between CPT-MBF, TFV and other CRFs were assessed using non-parametric Spearman rank correlation testing and multivariate linear regression analysis. All of the 50 participants (58 ± 10y) had normal stress-MBF (2.7 ± 0.6 mL/min/g; 95 % CI: 2.6-2.9) and myocardial flow reserve (2.8 ± 0.8; 95 % CI: 2.6-3.0) excluding underlying CAD. Univariate analysis revealed a significant inverse relation between absolute CPT-MBF and sex (ρ = -0.47, p = 0.0006), triglyceride (ρ = -0.32, p = 0.024) and insulin levels (ρ = -0.43, p = 0.0024), HOMA-IR (ρ = -0.39, p = 0.007), BMI (ρ = -0.51, p = 0.0002) and TFV (ρ = -0.52, p = 0.0001). MBF response to adenosine was also correlated with TFV (ρ = -0.32, p = 0.026). On multivariate analysis, TFV emerged as the only significant predictor of MBF response to CPT (p = 0.014). TFV is significantly correlated with endothelium-dependent and -independent coronary vasomotion. High TF burden might negatively influence MBF response to CPT and to adenosine stress, even in persons without CAD, suggesting a link between thoracic fat and future cardiovascular events. (orig.)

    Despite being commonly affected by degenerative disorders, there are few data on normal thoracic intervertebral disc dimensions. A morphometric analysis of adult thoracic intervertebral discs was, therefore, undertaken. Archival computed tomography scans of 128 recently deceased individuals (70 males, 58 females, 20-79 years) with no known spinal pathology were analysed to determine thoracic disc morphometry and variations with disc level, sex and age. Reliability was assessed by intraclass correlation coefficients (ICCs). Anterior and posterior intervertebral disc heights and axial dimensions were significantly greater in men (anterior disc height 4.0±1.4 vs 3.6±1.3 mm; posterior disc height 3.6±0.90 vs 3.4±0.93 mm; p<0.01). Disc heights and axial dimensions at T4-5 were similar or smaller than at T2-3, but thereafter increased caudally (mean anterior disc height T4-5 and T10-11, 2.7±0.7 and 5.4±1.2 mm, respectively, in men; 2.6±0.8 and 5.1±1.3 mm, respectively, in women; p<0.05). Except at T2-3, anterior disc height decreased with advancing age and anteroposterior and transverse disc dimensions increased; posterior and middle disc heights and indices of disc shape showed no consistent statistically significant changes. Most parameters showed substantial to almost perfect agreement for intra- and inter-rater reliability. Thoracic disc morphometry varies significantly and consistently with disc level, sex and age. This study provides unique reference data on adult thoracic intervertebral disc morphometry, which may be useful when interpreting pathological changes and for future biomechanical and functional studies.

  12. Exposure to 100% Oxygen Abolishes the Impairment of Fracture Healing after Thoracic Trauma.

    Directory of Open Access Journals (Sweden)

    Julia Kemmler

    Full Text Available In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients.

    Interleukin (IL)-22 plays important roles in the development of arterial disease, including atherosclerosis and hypertension. However, the relationship between IL-22 and acute thoracic aortic dissection (TAD) remains unknown. Blood samples were collected from patients with chest pain who underwent computed tomography angiography of the thoracic aorta but had no known preoperative diagnosis of coronary artery disease, peripheral artery disease, arthritis, and/or membranous nephropathy. Patients were divided into non-AD (NAD) and TAD groups, and the plasma concentrations of IL-22, IL-6 and tumor necrosis factor (TNF)-α were measured. In addition, aortic tissue samples from acute TAD patients and normal donors were collected, and the expression levels of IL-22 and IL-22 receptor 1 (IL-22R1) were measured. IL-22, IL-6 and TNF-α levels were significantly higher in acute TAD patients than in NAD patients (IL-22, NAD group: 27.0 (19.1, 38.6) pg/ml vs. TAD group: 32.9 (20.6, 58.3) pg/ml, pTAD (OR 1.169, 95% CI 1.069 to 1.277; p=0.001). In addition, compared with aortic tissue of normal controls, TAD aortas showed increased expression of IL-22 and IL-22R1, especially in the torn section (IL-22, non-torn section: 2.8±0.5/HPF vs. torn section 2.8±0.5/HPF, pTAD.

    This audit examines our total experience with penetrating thoracic trauma. It reviews all the patients who were brought alive to our surgical service and all who were taken directly to the mortuary. The group of patients who underwent emergency operation for penetrating thoracic trauma is examined in detail. A prospective trauma registry is maintained by the Pietermaritzburg Metropolitan Complex. This database was retrospectively interrogated for all patients requiring an emergency thoracic operation for penetrating injury from July 2006 till July 2009. A retrospective review of mortuary data for the same period was undertaken to identify patients with penetrating thoracic trauma who had been taken to the forensic mortuary. Over the 3-year period July 2006 to July 2009, a total of 1186 patients, 77 of whom were female, were admitted to the surgical services in Pietermaritzburg with penetrating thoracic trauma. There were 124 gunshot wounds and 1062 stab wounds. A total of 108 (9%) patients required emergency operation during the period under review. The mechanism of trauma in the operative group was stab wounds (n = 102), gunshot wound (n = 4), stab with compass (n = 1), and impalement by falling on an arrow (n = 1). Over the same period 676 persons with penetrating thoracic trauma were taken to the mortuary. There were 135 (20%) gunshot wounds of the chest in the mortuary cohort. The overall mortality for penetrating thoracic trauma was 541 (33%) of 1603 for stab wounds and 135 (52%) of 259 for gunshot wounds of the chest. Among the 541 subjects with stab wounds from the mortuary cohort, there were 206 (38%) with cardiac injuries. In the emergency operation group there were 11 (10%) deaths. In 76 patients a cardiac injury was identified. The other injuries identified were lung parenchyma bleeding (n = 12) intercostal vessels (n = 10), great vessels of the chest (n = 6), internal thoracic vessel (n = 2), and pericardial injury with no myocardial injury (n = 2

    The impact of Society of Thoracic Surgeons predicted mortality risk score on resource use has not been previously studied. We hypothesize that increasing Society of Thoracic Surgeons risk scores in patients undergoing aortic valve replacement are associated with greater hospital charges. Clinical and financial data for patients undergoing aortic valve replacement at The Johns Hopkins Hospital over a 10-year period (January 2000 to December 2009) were reviewed. The current Society of Thoracic Surgeons formula (v2.61) for in-hospital mortality was used for all patients. After stratification into risk quartiles, index admission hospital charges were compared across risk strata with rank-sum and Kruskal-Wallis tests. Linear regression and Spearman's coefficient assessed correlation and goodness of fit. Multivariable analysis assessed relative contributions of individual variables on overall charges. A total of 553 patients underwent aortic valve replacement during the study period. Average predicted mortality was 2.9% (±3.4) and actual mortality was 3.4% for aortic valve replacement. Median charges were greater in the upper quartile of patients undergoing aortic valve replacement (quartiles 1-3, $39,949 [interquartile range, 32,708-51,323] vs quartile 4, $62,301 [interquartile range, 45,952-97,103], P < .01]. On univariate linear regression, there was a positive correlation between Society of Thoracic Surgeons risk score and log-transformed charges (coefficient, 0.06; 95% confidence interval, 0.05-0.07; P < .01). Spearman's correlation R-value was 0.51. This positive correlation persisted in risk-adjusted multivariable linear regression. Each 1% increase in Society of Thoracic Surgeons risk score was associated with an added $3000 in hospital charges. This is the first study to show that increasing Society of Thoracic Surgeons risk score predicts greater charges after aortic valve replacement. As competing therapies, such as percutaneous valve replacement, emerge to

    As the largest scientific organisation world-wide exclusively dedicated to general thoracic surgery (GTS), the European Society of Thoracic Surgeons (ESTS) recognized that one of its priorities is education. The educational platform designed ESTS addresses not only trainees, but also confirmed thoracic surgeons. The two main aims are (I) to prepare trainees to graduation and to the certification by the European Board of Thoracic Surgery and (II) to offer opportunities for continuous medical education in the perspective of life-long learning and continuous professional development to certified thoracic surgeons. It is likely that recertification will become an obligation during the coming decade. At its inception, the platform differentiated two different events. A 6-day course emphasizing on theoretic knowledge was created in Antalya in 2007. The same year, a 2-day school oriented to practical issues with hands-on in the animal lab was launched in Antalya. These two teaching tracks need further development. In the knowledge track, we intend to organize highly specialized 2-day courses to deepen insight into theoretical questions. The skill track will be implemented by specialized courses for high technology such as tracheal surgery, ECMO, robotics or chest wall reconstruction. In order to promote tomorrows' leadership, we created an academic competence track giving an insight into medical communication, methodology and management. We also had to respond to an increasing demand from the Russian speaking countries, where colleagues may face problems to attend western meetings, and where the language bareer may be a major impediment. We initiated a Russian school with three events yearly in 2012. Contemporary teaching must be completed with an e-learning platform, which is currently under development. The school activities are organized by the educational committee, which is headed by the ESTS Director of Education, assisted by coordinators of the teaching tracks and

    We describe the optimal protocol of magnetic resonance-thoracic ductography (MRTD) and provide examples of thoracic ducts (TD) and various anomalies. The anatomical pathway of the TD was analyzed based on embryological considerations. A total of 78 subjects, consisting of noncancer adults and patients with esophageal cancer and lung cancer, were enrolled. The MRTD protocol included a long echo time and was based on emphasizing signals from the liquid fraction and suppressing other signals, based on the principle that lymph flow through the TD appears hyperintense on T2-weighted images. The TD configuration was classified into nine types based on location [right and/or left side(s) of the descending aorta] and outflow [right and/or left venous angle(s)]. MRTD was conducted in 78 patients, and the three-dimensional reconstruction was considered to provide excellent view of the TD in 69 patients, segmentalization of TD in 4, and a poor view of the TD in 5. MRTD achieved a visualization rate of 94%. Most of the patients had a right-side TD that flowed into the left venous angle. Major configuration variations were noted in 14% of cases. Minor anomalies, such as divergence and meandering, were frequently seen. MRTD allows noninvasive evaluation of TD and can be used to identify TD configuration. Thus, this technique is considered to contribute positively to safer performance of thoracic surgery. (author)

    The purpose of this study was to identify the effects of a corrective exercise for thoracic hyperkyphosis on posture, balance, and well-being in Korean community-dwelling older women. Fifty women 65 years of age and older, recruited from 2 senior centers, participated in this study. Participants were assigned to either the experimental group (EG) or the control group (CG) on the basis of convenience of location, and 22 in each were analyzed. Participants in the EG underwent a thoracic corrective exercise program 1 hour each session, twice per week for 8 weeks (a total of 16 sessions), which consisted of specific exercises to enhance breathing, thoracic mobility and stability, and awareness of thoracic alignment. The CG received education on the same thoracic corrective exercise program and a booklet of the exercises. Outcome measures included the extent of postural abnormality (angle of thoracic kyphosis, kyphosis index calculated both in relaxed- and best posture using flexicurve, the ratio of the kyphosis index calculated best posture/relaxed posture, craniovertebral angle, and tragus-to-wall distance), balance (Short Physical Performance Battery and limit of stability), and well-being (Geriatric Depression Scale Short Form and the 36-Item Short Form Health Survey [SF-36]). All data were collected by 6 blinded assessors at baseline, at 8 weeks after the completion of intervention, and at 16 weeks for follow-up. For participants of the EG, means of all parameters showed significant improvements over time (P posture, balance, and well-being in older women with thoracic hyperkyphosis. We recommend the use of the therapeutic strategies utilized in this study to enhance thoracic posture, balance, and well-being of older women with thoracic hyperkyphosis. Future research is needed to apply this exercise protocol on a larger and more diverse population.

    In a first part, the different techniques of digital thoracic radiography are described. Since computed radiography with phosphore plates are the most commercialized it is more emphasized. But the other detectors are also described, as the drum coated with selenium and the direct digital radiography with selenium detectors. The other detectors are also studied in particular indirect flat panels detectors and the system with four high resolution CCD cameras. In a second step the most important image processing are discussed: the gradation curves, the unsharp mask processing, the system MUSICA, the dynamic range compression or reduction, the soustraction with dual energy. In the last part the advantages and the drawbacks of computed thoracic radiography are emphasized. The most important are the almost constant good quality of the pictures and the possibilities of image processing.

    BACKGROUND: Road deaths fell initially after the introduction of the penalty points but despite this, the rate of spinal injuries remained unchanged. AIMS: We report a patient with a dramatic spinal injury, though without neurological deficit. We discuss the classification, management and economic impact of these injuries. METHODS: We describe the management of a patient with a comminuted thoracic spinal fracture without neurological injury. We conducted a literature review with regard to the availability of literature of the management of these injuries. RESULTS: This 17-year-old female was managed surgically and had a good functional outcome. There is no clear consensus in the published literature on the management of these injuries. CONCLUSIONS: Comminuted thoracic spinal factures are potentially devastating. Such a patient presents challenges in determining the appropriate treatment.

    The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

    Thoracic endometriosis is considered to be rare, but is the most frequent form of extra-abdominopelvic endometriosis. Thoracic endometriosis syndrome affects women of reproductive age. Diagnosis is mainly based on clinical findings, which can include catamenial pneumothorax and haemothorax, non-catamenial endometriosis-related pneumothorax, catamenial haemoptysis, lung nodules, and isolated catamenial chest pain. Symptoms are typically cyclical and recurrent, with a right-sided predominance. Computed tomography (CT) is the first-line imaging method, but is poorly specific; therefore, its main role is to rule out other pulmonary diseases. However, in women with a typical clinical history, some key CT findings may help to confirm this often under-diagnosed syndrome. MRI can also assist with the diagnosis, by showing signal changes typical of haemorrhage within diaphragmatic or pleural lesions

  10. Epidemiology and pathogenesis of thoracic outlet syndrome

    Directory of Open Access Journals (Sweden)

    Wojcik Gustaw

    2015-03-01

    Full Text Available The superior thoracic aperture is a place particularly vulnerable to the occurrence of tissue conflict and the development of a number of neurovascular changes carrying a risk of upper limb dysfunction. The triggering factor in this case is the pressure on the nerve vascular elements brought about by too large muscles of the chest and neck, clavicle fracture and dislocation of the upper ribs, anomalies in the form of ribs, in the neck, or by apex of the lung tumors. Each anatomical anomaly may be a cause of a number of lesions and lead to the development of the disease. Due to the nature of the oppressed structures, there are two basic groups: neurogenic and vascular. The most common variant giving clinical symptoms is neurogenic thoracic outlet syndrome. In this, the compression ratio, the brachial plexus, and for this reason, the vascular surface of the upper limb dysfunction is often overlooked. However, the vascular variant, and especially arterial sub-variant, is very dangerous because it can give complications even in the form of aneurysms, and even upper limb ischemia. The aim of the study is to present the most common changes in the thoracic outlet causing functional disorders of the upper limb.

    Severe thoracic sarcoidosis includes manifestations with significant clinical and functional impairment and a risk of mortality. Severe thoracic sarcoidosis can take on various clinical presentations and is associated with increased morbidity. The purpose of this article was to describe the CT findings in severe thoracic sarcoidosis and to explain some of their mechanisms. Subacute respiratory insufficiency is a rare and early complication due to a high profusion of pulmonary lesions. Chronic respiratory insufficiency due to pulmonary fibrosis is a frequent and late complication. Three main CT patterns are identified: bronchial distortion, honeycombing and linear opacities. CT can be helpful in diagnosing some mechanisms of central airway obstruction such as bronchial distortion due to pulmonary fibrosis or an extrinsic bronchial compression by enlarged lymph nodes. An intrinsic narrowing of the bronchial wall by endobronchial granulomatous lesions may be suggested by CT when it shows evidence of bronchial mural thickening. Pulmonary hypertension usually occurs in patients with end-stage pulmonary disease and is related to fibrotic destruction of the distal capillary bed and to the resultant chronic hypoxemia. Several other mechanisms may contribute to the development of pulmonary hypertension including extrinsic compression of major pulmonary arteries by enlarged lymph nodes and secondary pulmonary veno-occlusive disease. Aspergilloma colonization of a cavity is the main cause of hemoptysis in sarcoidosis. Other rare causes are bronchiesctasis, necrotizing bronchial aspergillosis, semi-invasive pulmonary aspergillosis, erosion of a pulmonary artery due to a necrotic sarcoidosis lesion, necrosis of parenchymal sarcoidosis lesions and specific endobronchial macroscopic lesions.

    Iyoda, A; Satoh, Y

    2012-07-01

    Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

    Patients with thoracic aorta injuries (TAI) present a unique challenge. The purpose of this study was to review the outcomes of thoracic endovascular aortic repair (TEVAR) in patients with TAI. A retrospective chart review of all patients admitted for TEVAR for trauma was performed. In a 5-year period, 19 patients (6 women and 13 men; average age, 42 y) were admitted to our trauma center with TAI. Mechanism of injury was a motor vehicle crash in 12 patients, motorcycle crash in 2 patients, automobile-pedestrian accident in 2 patients, 1 fall, 1 crush injury, and 1 stab wound to the back. A thoracic endograft was used in 6 patients and proximal aortic cuffs were used in 13 patients (68%). One patient (5%) died. There were no strokes, myocardial infarctions, paraplegia, or renal failure. TEVAR for TAI appears to be a safe option for patients with multiple injuries. TEVAR in young patients is still controversial because long-term endograft behavior is unknown. Copyright © 2012 Elsevier Inc. All rights reserved.

  15. Robotics in general thoracic surgery procedures.

    Science.gov (United States)

    Latif, M Jawad; Park, Bernard J

    2017-01-01

    The use of robotic technology in general thoracic surgical practice continues to expand across various institutions and at this point many major common thoracic surgical procedures have been successfully performed by general thoracic surgeons using the robotic technology. These procedures include lung resections, excision of mediastinal masses, esophagectomy and reconstruction for malignant and benign esophageal pathologies. The success of robotic technology can be attributed to highly magnified 3-D visualization, dexterity afforded by 7 degrees of freedom that allow difficult dissections in narrow fields and the ease of reproducibility once the initial set up and instruments become familiar to the surgeon. As the application of robotic technology trickle downs from major academic centers to community hospitals, it becomes imperative that its role, limitations, learning curve and financial impact are understood by the novice robotic surgeon. In this article, we share our experience as it relates to the setup, common pitfalls and long term results for more commonly performed robotic assisted lung and thymic resections using the 4 arm da Vinci Xi robotic platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA) to help guide those who are interested in adopting this technology.

    Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

    Chylopericardium rarely occurs in pediatric patients, but when it does it is most often a result of lymphatic injury during cardiothoracic surgery. Primary idiopathic chylopericardium is especially rare, with few cases in the pediatric literature. We report a 10-year-old boy who presented with primary idiopathic chylopericardium after unsuccessful initial treatment with surgical lymphatic ligation and creation of a pericardial window. Following readmission to the hospital for a right-side chylothorax resulting from the effluent from the pericardial window, he had successful treatment by interventional radiology with percutaneous thoracic duct embolization. This case illustrates the utility of thoracic duct embolization as a less-invasive alternative to surgical thoracic duct ligation, or as a salvage procedure when surgical ligation fails. (orig.)

    Full Text Available Giant cell tumor (GCT is a benign but locally aggressive skeletal neoplasm of young adults. GCT located in the spine is relatively rare and may need a combination of surgical and adjunctive therapies. Here we present a patient who had intermittent thoracic back pain for two weeks and experienced an acute episode of decreased muscle power of both lower limbs. Magnetic resonance (MR imaging examinations of the thoracic spine revealed that the patient had severe spinal canal compression caused by pathological fracture due to a tumor within the seventh thoracic vertebra. She underwent an emergent surgical intervention for total removal of the tumor and spinal reconstruction with autologous rib grafts and instruments. Postoperatively, the patient made an uneventful recovery of muscle power of bilateral lower limbs. She subsequently received adjuvant radiotherapy. In a follow-up period of 36 months, the patient had no clinical or radiological evidence of tumor recurrence. Even though spinal location for GCT is a rare event, it should be included in the differential diagnosis in patients with osteolytic lesions or pathological fractures of the vertebra, especially in young female patients sustaining no trauma who had a clinical history of persistent low back pain.

    Thoracic aortic operations still remain associated with substantial risks of death and neurologic injury. This study investigated the impact of surgical stroke on the early and late outcomes, focusing on the physical status and quality of life (QOL). From 1986 to 2008, 500 patients (aged 63 ± 13 years) underwent open thoracic aortic repair for root and ascending (31%), arch (39%), extended arch (10%), and descending and thoracoabdominal (19%) aneurysms. Brain protection consisted of retrograde cerebral perfusion (52%), antegrade cerebral perfusion (29%), and simple deep hypothermic circulatory arrest (19%). Surgical stroke was defined as a neurologic deficit persisting more than 72 hours after the operation. QOL was assessed with the Short-Form 36 Health Survey Questionnaire 5.9 ± 4.2 years after the operation. Stroke occurred in 10.3% of patients. Hospital mortality was 21% in the stroke group and 2.7% in the nonstroke group (p mental component was similar in both groups (14% vs 14%). Surgical stroke is associated with high hospital mortality and PNDs that decrease late survival and the physical component score of the QOL survey. Copyright © 2015 The Society of Thoracic Surgeons.

    Multimodal therapeutic concepts in cases of neoplasms of the intestinal tract entail the risk of undesirable complications with respect to healing of wounds and anastomoses. The separate steps of a combined treatment consisting radiation therapy and partial resection of the thoracic esophagus were performed in animal experiments to study the effect of radiation therapy on the healing of anastomoses. Adult non-purebred dogs were irradiated in a defined thoracic field with a Betatron (42 MeV) and subsequently underwent esophagectomy. After resection of a 2 cm segment of the esophagus end-to-end anastomosis was performed. Different methods of irradiation and postoperative observation times resulted in a total of 8 groups of 3 animals each. Fractionated irradiation was definitely better tolerated than irradiation with a high single doses. The temporary delay of the anastomotic healing was documented histologically. Only one case of anastomotic leakage occurred, and impaired wound healing was observed in only one animal. The mode of irradiation must be regarded as important for the clinical course. Fractionated preoperative irradiation in the area of the thoracic esophagus does not lead to any relevant disturbance of wound and anastomotic healing with meticulous surgical technique and adequate intensive postoperative care. The basic feasibility of surgical therapy combined with preoperative radiotherapy in tumors of the upper digestive tract was confirmed by our experimental work.

    To evaluate the incidence of additional thoracic pathologic findings (TPF) detected on scout views and corresponding bolus tracking slices (SVBT) for computed tomographic cerebral angiography (CTCA) and to test the reliability and accuracy of these findings. The study collective included 505 consecutive patients who underwent multidetector CTCA. Appendant SVBT of all patients were reviewed for any pathologic findings and patient medical reports were analyzed, if any medical treatment was initiated for the detected pathologic findings. In 18 patients thoracic CT scans were performed in the same session. These were additionally reviewed by two blinded observers to test for intra- and interobserver reliability as well as for accuracy of detecting thoracic pathologies on SVBT. TPF were detected in 165 (33 %) SVBT. The five most common pathologic findings were: pleural effusion, 12 %; pneumonia, 8 %; atelectasis/dystelecatsis, 6 %; pericardial effusion, 2 % and elevated diaphragm, 1 %. For 48 % of these findings medical treatment was initiated. SVBT showed a sensitivity of 53 %, a specificity of 99 %, a positive predictive value of 89 %, a negative predictive value of 94 % and accuracy of 94 % for the detection of TPF. The intraobserver reliability was very good and the interobserver reliability showed moderate agreement. SVBT for CTCA should be reviewed with care by radiologists, since additional TPF can affect patient management. Nevertheless, despite a high specificity of SVBT for detecting TPF, an only moderate sensitivity has to be taken into account.

    Arterial inflammation and vascular calcification are regarded as early prognostic markers of cardiovascular disease (CVD). In this study we investigated the relationship between CVD risk and arterial inflammation ({sup 18}F-FDG PET/CT imaging), vascular calcification metabolism (Na{sup 18}F PET/CT imaging), and vascular calcium burden (CT imaging) of the thoracic aorta in a population at low CVD risk. Study participants underwent blood pressure measurements, blood analyses, and {sup 18}F-FDG and Na{sup 18}F PET/CT imaging. In addition, the 10-year risk for development of CVD, based on the Framingham risk score (FRS), was estimated. CVD risk was compared across quartiles of thoracic aorta {sup 18}F-FDG uptake, Na{sup 18}F uptake, and calcium burden on CT. A total of 139 subjects (52 % men, mean age 49 years, age range 21 - 75 years, median FRS 6 %) were evaluated. CVD risk was, on average, 3.7 times higher among subjects with thoracic aorta Na{sup 18}F uptake in the highest quartile compared with those in the lowest quartile of the distribution (15.5 % vs. 4.2 %; P < 0.001). CVD risk was on average, 3.7 times higher among subjects with a thoracic aorta calcium burden on CT in the highest quartile compared with those in the lowest two quartiles of the distribution (18.0 % vs. 4.9 %; P < 0.001). CVD risk was similar in subjects in all quartiles of thoracic aorta {sup 18}F-FDG uptake. Our findings indicate that an unfavourable CVD risk profile is associated with marked increases in vascular calcification metabolism and vascular calcium burden of the thoracic aorta, but not with arterial inflammation.

    The safety and feasibility of supra-aortic debranching as part of endovascular aortic surgery or as a treatment option for arterial occlusive disease (AOD) remains controversial. The aim of this study was to assess the clinical outcome of this surgery. This single centre, retrospective study included 107 patients (mean age 69.2 years, 38.4% women) who underwent supra-aortic bypass surgery (carotid-subclavian bypass, carotid-carotid bypass, and carotid-carotid-subclavian bypass) because of thoracic or thoraco-abdominal endovascular aortic repair (57%; 61/107) or as AOD treatment (42.9%; 46/107) between January 2006 and January 2015. Mortality, morbidity with a focus on neurological complications, and patency rate were assessed. Twenty-six of 107 (14.2%) of the debranching patients were treated under emergency conditions because of acute type B dissection or symptomatic aneurysm. Follow up, conducted by imaging interpretation and telephone interviews, continued till March 2017 (mean 42.1, 0-125, months). The in hospital mortality rate was 10.2% (11/107), all of these cases from the debranching group and related to emergency procedures (p supra-aortic bypass surgery involves low complication rates and high mid-term bypass patency rates. It is a safe and feasible treatment option in the form of debranching in combination with endovascular aortic aneurysm repair and in AOD. Copyright © 2018 European Society for Vascular Surgery.

    Thoracic aortic emergencies account for 10% of thoracic-related admissions in the United States and remain associated with high morbidity and mortality rates. Open repair has declined owing to the emergence of thoracic endovascular aortic repair (TEVAR), but data on emergency TEVAR use for acute aortic pathology remain limited. We therefore reviewed our experience. We retrospectively evaluated emergency descending thoracic aortic endovascular interventions performed at a single academic level 1 trauma center between January 2005 and August 2013 including all cases of traumatic aortic injury, ruptured descending thoracic aneurysm, penetrating atherosclerotic ulcer, aortoenteric fistula, and acute complicated type B dissection. Demographics, clinical data, and outcomes were extracted. Stepwise logistic regression was used to identify independent risk factors for death. During the study period, 51 patients underwent TEVAR; 22 cases (43.1%) were performed emergently (11 patients [50.0%] traumatic aortic injury; 4 [18.2%] ruptured descending thoracic aneurysm; 4 [18.2%] complicated type B dissection; 2 [9.1%] penetrating aortic ulcer; and 1 [4.5%] aortoenteric fistula). Overall, 72.7% (n = 16) were male with a mean age of 54.8 ± 15.9 years. Nineteen patients (86.4%) required only a single TEVAR procedure, whereas 2 (9.1%) required additional endovascular therapy, and 1 (4.5%) open thoracotomy. Four traumatic aortic injury patients required exploratory laparotomy for concomitant intra-abdominal injuries. During a mean hospital length of stay of 18.9 days (range, 1 to 76 days), 3 patients (13.6%) developed major complications. In-hospital mortality was 27.2%, consisting of 6 deaths from traumatic brain injury (1); exsanguination in the operating room before repair could be achieved (2); bowel ischemia (1) and multisystem organ failure (1); and family withdrawal of care (1). A stepwise logistic regression model identified 24-hour packed red blood cell requirements ≥4

    The aim of this study was to assess the relationship between radiation therapy (RT) and treatment-related mortality in patients receiving high-dose chemotherapy (HDCT) and autologous bone marrow transplantation (ABMT) for recurrent/refractory Hodgkin's disease (HD). Between December 1986 and December 1992, 59 patients previously treated at the Princess Margaret Hospital underwent HDCT (etoposide 60 mg/kg, melphalan 160 mg/m 2 ) and ABMT, performed for refractory (13 patients) or relapsed (46 patients) HD. RT was incorporated in the salvage treatment with the intent to achieve complete control of disease prior to ABMT. RT was given before ABMT in 33 patients, and after ABMT in 4 patients. Treatment-related (TR) mortality was defined as any death occurring within 100 days of ABMT. Autopsies were performed for all patients with TR deaths. With a median follow-up of 4.6 years (range 1.2-7.4 years), the actuarial overall survival was 41%±14% at 5 years. We observed 37 deaths, and 10 of these were TR deaths. Among the 24 patients who received thoracic RT before ABMT, there were 8 TR deaths, 3 of these solely attributable to radiation pneumonitis. The remaining 5 TR deaths all had respiratory failure with complicating sepsis as a major medical problem. The interval from RT to ABMT was shorter for 8 patients dying of TR death (mean 37 days; range 0-103 days), than for the 16 survivors (mean 105 days; range 0-263 days) (P=0.026). Among 9 patients with ABMT within 50 days of thoracic RT, 6 had TR death. In contrast, among the 35 patients without thoracic RT (26 no RT, 9 non-thoracic RT), there were only 2 TR deaths. The 4 patients treated with mantle RT post-ABMT had no serious pulmonary complications. The use of thoracic RT before HDCT and ABMT was associated with a high post-transplant mortality rate. It was most evident in patients who received thoracic RT within 50 days prior to ABMT, or when the target volume included large volume of lung. We recommend that the use of

    To evaluate the diagnostic role of venous and arterial duplex scanning in neurogenic thoracic outlet syndrome (NTOS). Retrospective review of patients who underwent duplex ultrasonography prior to first rib resection and scalenectomy (FRRS) for NTOS from 2005 to 2013. Abnormal scans included ipsilateral compression (IC) with abduction of the symptomatic extremity (>50% change in subclavian vessel flow), contralateral (asymptomatic side) compression (CC) or bilateral compression (BC). A total of 143 patients (76% female, average age 34, range 13-59) underwent bilateral preoperative duplex scanning. Ipsilateral compression was seen in 44 (31%), CC in 12 (8%), and BC in 14 (10%). Seventy-three (51%) patients demonstrated no compression. Patients with IC more often experienced intraoperative pneumothoraces (49% vs. 25%, P duplex ultrasonography can assist in NTOS diagnosis. Ipsilateral compression on abduction often correlates with Adson testing. © The Author(s) 2016.

    Abstract Literature examining magnetic resonance imaging (MRI) in acute spinal cord injury (SCI) has focused on cervical SCI. Reproducible systems have been developed for MRI-based grading; however, it is unclear how they apply to thoracic SCI. Our hypothesis is that MRI measures will group as coherent multivariate principal component (PC) ensembles, and that distinct PCs and individual variables will show discriminant validity for predicting early impairment in thoracic SCI. We undertook a retrospective cohort study of 25 patients with acute thoracic SCI who underwent MRI on admission and had American Spinal Injury Association Impairment Scale (AIS) assessment at hospital discharge. Imaging variables of axial grade, sagittal grade, length of injury, thoracolumbar injury classification system (TLICS), maximum canal compromise (MCC), and maximum spinal cord compression (MSCC) were collected. We performed an analytical workflow to detect multivariate PC patterns followed by explicit hypothesis testing to predict AIS at discharge. All imaging variables loaded positively on PC1 (64.3% of variance), which was highly related to AIS at discharge. MCC, MSCC, and TLICS also loaded positively on PC2 (22.7% of variance), while variables concerning cord signal abnormality loaded negatively on PC2. PC2 was highly related to the patient undergoing surgical decompression. Variables of signal abnormality were all negatively correlated with AIS at discharge with the highest level of correlation for axial grade as assessed with the Brain and Spinal Injury Center (BASIC) score. A multiple variable model identified BASIC as the only statistically significant predictor of AIS at discharge, signifying that BASIC best captured the variance in AIS within our study population. Our study provides evidence of convergent validity, construct validity, and clinical predictive validity for the sampled MRI measures of SCI when applied in acute thoracic and thoracolumbar SCI.

    The aim of this study was to assess the influence of thoracic anterior radiculomedullary artery (tARMA) distribution on spinal cord perfusion in a thoracic aortic surgical model. Twenty-six pigs (34 ± 3 kg; study group, n = 20; sham group, n = 6) underwent ligation of the left subclavian artery and thoracic segmental arteries. End points were spinal cord perfusion pressure (SCPP), regional spinal cord blood flow (SCBF), and neurologic outcome with an observation time of 3 hours. tARMA distribution patterns tested for an effect on end points included (1) maximum distance between any 2 tARMAs within the treated aortic segment (0 or 1 segment = small-distance group; >1 segment = large-distance group) and (2) distance between the end of the treated aortic segment and the first distal tARMA (at the level of the distal simulated stent-graft end = group 0; gap of 1 or more segments = group ≥1). The number of tARMA ranged from 3 to 13 (mean, 8). In the large-distance group, SCBF dropped from 0.48 ± 0.16 mL/g/min to 0.3 ± 0.08 mL/g/min (p distribution patterns of tARMAs correlate with the degree of SCBF drop and insufficient reactive parenchymal hyperemia in aortic procedures. Individual ARMA distribution patterns along the treated aortic segment could help us predict the individual risk of spinal ischemia. Copyright © 2017 The Society of Thoracic Surgeons.

    The use of ultrasound in peripheral thoracic lesions offers advantages over other radiological guiding methods. This diagnostic procedure has been applied in most studies published by radiologists. Our aim was to determine the diagnostic efficacy of percutaneous ultrasound-guided punctures and biopsies of peripheral thoracic lesions performed by pulmonologists. A retrospective analysis of 58 patients who underwent real-time ultrasound-guided transthoracic punctures and biopsy of peripheral thoracic lesions between March 2011 and September 2014 in the pulmonology department of our hospital. Cases were classified into the following diagnostic categories: malignant, benign and non-diagnostic (non-specific benign without evidence of malignancy and insufficient specimen). A conclusive diagnosis was obtained in 47 procedures (81%), of which 13 (22.4%) were specific benign lesions and 34 (58.6%) cancers. In the remaining 11 (19%) patients, a non-diagnostic result was obtained [non-specific benign in 5 cases (8.6%) and insufficient specimen in 6 (10.3%)]. Sensitivity was 75.6%, negative predictive value was 54.2%, specificity and positive predictive value were 100%, and diagnostic accuracy was 81%. Excluding procedures with insufficient specimens, the results were 87.2%, 72.3%, 100%, 100% and 90.4% respectively. There were no serious complications. Percutaneous ultrasound-guided puncture and biopsy in the diagnosis of peripheral thoracic lesions performed by pulmonologists is a safe procedure with high diagnostic accuracy. We achieved similar results to those previously obtained by radiologists. Copyright © 2015 SEPAR. Published by Elsevier Espana. All rights reserved.

    A 70-year-old man with distal bile duct carcinoma underwent a subtotal stomach-preserving pancreaticoduodenectomy without adjuvant chemotherapy. One and a half years after the surgery, elevated levels of serum SPan-1(38.1 U/mL)were observed and CT scans demonstrated a solitary metastasis, 25mm in size, in segment 8 of the liver. The patient received 2 courses of gemcitabine-cisplatin combination chemotherapy. No new lesions were detected after chemotherapy and the patient underwent a partial liver resection of segment 8. The pathological examination revealed a metachronous distant metastasis originating from the bile duct carcinoma. Subsequently, the patient received S-1 adjuvant chemotherapy for 6 months. Following completion of all therapies, the patient survived without tumor recurrence for 3 years and 10 months after the initial operation. Thus, surgical interventions might be effective in improving prognosis among selected patients with postoperative liver metastasis of bile duct carcinoma.

  13. Internal Thoracic Artery Encircled by an Unusual Phrenic Nerve Loop

    2007-12-01

    Full Text Available We report an anatomic variation of the phrenic nerve. During a routine gross anatomical dissection course at our medical university, we found an unusual loop of the left phrenic nerve around the internal thoracic artery, about 1 cm from the take-off of the left subclavian artery. The phrenic nerve is close to the internal thoracic artery and is easily injured when dissecting the internal thoracic artery for coronary artery bypass conduit. Therefore, we suggest that the anatomic relationship of the phrenic nerve and internal thoracic artery is important in preventing incidental injury of the phrenic nerve.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Accurate knowledge of surface anatomy is fundamental to safe clinical practice. A paucity of evidence in the literature regarding thoracic surface anatomy in children was identified. The associations between surface landmarks and internal structures were meticulously analyzed by reviewing high quality computed tomography (CT) images of 77 children aged from four days to 12 years. The results confirmed that the sternal angle is an accurate surface landmark for the azygos-superior vena cava junction in a plane through to the level of upper T4 from birth to age four, and to lower T4 in older children. The concavity of the aortic arch was slightly below this plane and the tracheal and pulmonary artery bifurcations were even lower. The cardiac apex was typically at the 5 th intercostal space (ICS) from birth to age four, at the 4 th ICS and 5 th rib in 4-12 year olds, and close to the midclavicular line at all ages. The lower border of the diaphragm was at the level of the 6 th or 7 th rib at the midclavicular line, the 7 th ICS and 8 th rib at the midaxillary line, and the 11 th thoracic vertebra posteriorly. The domes of the diaphragm were generally flatter and lower in children, typically only one rib level higher than its anterior level at the midclavicular line. Diaphragm apertures were most commonly around the level of T9, T10, and T11 for the IVC, esophagus and aorta, respectively. This is the first study to provide an evidence-base for thoracic surface anatomy in children. Clin. Anat. 30:788-794, 2017. © 2017Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Homer's Iliad is considered to be a prominent and representative work of the tradition of the ancient Greek epic poetry. In this poem Homer presents the battles which took place during the last year of the 10-year lasting Trojan War between Achaeans and Trojans. We wanted to examine the chest wounds, especially those which are described in detail, according to their localization, severity and mortality. Finally, there are reported 54 consecutive thoracic injuries in the Iliad. The mostly used weapons were the spear (63%, the stones (7.4%, the arrow (5.5% and the sword (5.5%. We divided the injuries according to their severity in mild (those which did not cause serious injury to the victim, medium (those which cause the victim to abandon the battlefield, and severe (those which cause death of the victim. According to this classification, the reported injuries were mild in 11.11%, medium in 18.52%, and severe in the last 70.37% of the reported cases. In other words, 89% of the injuries belong to the medium or severe category of thoracic injury. As far as the mortality of the injuries is concerned, 38 out of 54 thoracic injuries include death, which makes the mortality percentage reach 70.37%. Concerning the "allocation of the roles", the Achaean were in 68% perpetrators and the Trojans in only 32%. In terms of gravity, out of 38 mortal injuries 30 involve a Trojan (78.95% and the remaining 8 an Achaean (21.05%. The excellent and detailed description of the injuries by Homer, as well as of the symptoms, may reveal a man with knowledge of anatomy and medicine who cared for the injured warriors in the battlefield.

    We analyzed the incidence of bradycardia and the safety of patients with severely calcified coronary lesions who underwent orbital atherectomy without the insertion of a temporary pacemaker. The presence of severely calcified coronary lesions can increase the complexity of percutaneous coronary intervention due to the difficulty in advancing and optimally expanding the stent. High-pressure inflations to predilate calcified lesions may cause angiographic complications like perforation and dissection. Suboptimal stent expansion is associated with stent thrombosis and restenosis. Orbital atherectomy safely and effectively modifies calcified plaque to facilitate optimal stent expansion. The incidence of bradycardia in orbital atherectomy is unknown. Fifty consecutive patients underwent orbital atherectomy from February 2014 to September 2016 at our institution, none of whom underwent insertion of a temporary pacemaker. The final analysis included 47 patients in this retrospective study as 3 patients were excluded because of permanent pacemaker implantation. The primary endpoint was significant bradycardia, defined as bradycardia requiring emergent pacemaker placement or a heart rate pacemaker appears to be safe.

    The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization. In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    We report a rare case of primary thoracic rhabdomyosarcoma in a girl who was referred with acute chest pain, hacking cough, and wheezing. A chest X-ray revealed a complete opacity of the right hemithorax. Ultrasound revealed a right-sided pleural effusion and a solid mass above the liver dome, suggesting a neoplastic disease, which quickly led to further specific examination. Use of CT and MRI together with bone scintigraphy completed the investigation. The biopsy specimen showed a pattern of alveolar rhabdomyosarcoma. This case was reported to emphasize the role of US in the evaluation of a child with hemithorax opacity. (orig.)

    Forty-three patients with acquired and congenital abnormalities of the thoracic aorta were studied using digital subtraction angiography (DSA) after an intravenous bolus injection of 40 ml of contrast material. Abnormalities studied included coarctation, pseudocoarctation, Marfan syndrome, cervical aorta, double aortic arch, aneurysm, dissection, and tumor. Twenty-four patients also had conventional angiography. DSA was accurate in 95% of cases; in the other 5%, involving patients with acute type I dissection, the coronary arteries could not be seen. The authors concluded that in 92% of their patients, DSA could have replaced the standard aortogram

    Computed tomography (CT) of the chest (chest CT) is overused in blunt pediatric thoracic trauma. Chest CT adds to the diagnosis of thoracic injury but rarely changes patient management. We sought to identify a subset of blunt pediatric trauma patients who would benefit from a screening chest CT based on their admission chest x-ray (CXR) findings. We hypothesize that limiting chest CT to patients with an abnormal mediastinal silhouette identifies intrathoracic vascular injuries not otherwise seen on CXR. All blunt trauma activations that underwent an admission CXR at our Level 1 pediatric trauma center from 2005 to 2013 were retrospectively reviewed. Patients who had a chest CT were evaluated for added diagnoses and change in management after CT. An admission CXR was performed in 1,035 patients. One hundred thirty-nine patients had a CT, and the diagnosis of intra-thoracic injury was added in 42% of patients. Chest CT significantly increased the diagnosis of contusion or atelectasis (30.3% vs 60.4%; p pneumothorax (7.2% vs 18.7%; p chest CT. Chest CT changed the management of only 4 patients (2.9%). Two patients underwent further radiologic evaluation that was negative for injury, one had a chest tube placed for an occult pneumothorax before exploratory laparotomy, and one patient had a thoracotomy for repair of aortic injury. Chest CT for select patients with an abnormal mediastinal silhouette on CXR would have decreased CT scans by 80% yet still identified patients with an intrathoracic vascular injury. The use of chest CT should be limited to the identification of intrathoracic vascular injuries in the setting of an abnormal mediastinal silhouette on CXR. Therapeutic study, level IV; diagnostic study, level III.

    Chest computed tomography (CCT) is used to screen for injuries in hemodynamically stable patients with penetrating injury. We aim to determine the incidence of missed injuries detected on CCT after a negative chest radiograph (CXR) in patients with thoracic stab wounds. A 10-year retrospective review of a Level I trauma center registry was performed on patients with thoracic stab wounds. Patients who were hemodynamically unstable or did not undergo both CXR and CCT were excluded. Patients with a negative CXR were evaluated to determine if additional findings were diagnosed on CCT. Of 386 patients with stab wounds to the chest, 154 (40%) underwent both CXR and CCT. One hundred and fifteen (75%) had a negative screening CXR. CCT identified injuries in 42 patients (37%) that were not seen on CXR. Pneumothorax and/or hemothorax occurred in 40 patients (35%), of which 14 patients underwent tube thoracostomy. Two patients had hemopericardium on CCT and both required operative intervention. Greater than one-third of patients with a normal screening CXR were found to have abnormalities on CCT. Future studies comparing repeat CXR to CCT are required to further define the optimal diagnostic strategy in patients with stab wounds to chest after normal screening CXR.

  10. Mid-Thoracic Spinal Injuries during Horse Racing: Report of 3 Cases and Review of Causative Factors and Prevention Measurements

    2013-01-01

    Full Text Available We report three cases of a rare pattern of mid-thoracic spine injuries after horse racing falls and discuss possible causative factors and prevention measurements to reduce injury rates in professional riding and racing. Three patients, 2 male and 1 female with a mean age of 28 years old, underwent surgical treatment for mid-thoracic fractures after professional equestrian activities. The ASIA scale was E in one patient, B in the other one and A in the third. Multilevel posterior fusion was used in two patients and somatectomy plus fusion in the other. Follow up evaluation included changing of the ASIA scale, functional outcome and participation in equestrian activities. One patient fully recovered after surgery. Two patients remained paraplegic despite early surgical treatment and prolonged rehabilitation therapy. All patients had ended their professional equestrian career. This report analyzes possible mechanisms of injury and the pattern of mid-thoracic spine fractures after professional horse riding injuries. Despite skill improvements and continued safety education for horse riding, prophylactic measures for both the head and the spine should be refined. According to our study, additional mid-thoracic spinal protection should be added.

  13. Thoracic Ganglioneuromas Resulting in Nonimmune Hydrops Fetalis

    Directory of Open Access Journals (Sweden)

    Paul Singh

    2014-05-01

    Full Text Available Introduction - Most often, ganglioneuromas affect older pediatric and adult patients. They are typically slow growing tumors that remain clinically silent until they become large enough to cause symptoms by compression of adjacent structures. Case - We report a case of a 22-year-old Hispanic gravida 2 para 1 female patient who was found to have massive hydrops fetalis at 20 completed gestational weeks. Fetal echocardiography revealed a narrowed distal ductal arch and proximal descending aorta. Cesarean delivery was undertaken at 29 completed gestational weeks for refractory labor and nonreassuring fetal status. The neonate expired at 47 minutes of life despite aggressive resuscitation. At autopsy, multiple thoracic masses were found adjacent to a compressed proximal descending aorta. Histological and immunohistochemical analysis confirmed the diagnosis of a ganglioneuroma, a rare type of neural crest tumor. Discussion - A variety of intrathoracic masses have previously been reported to cause hydrops fetalis including teratomas, fibrosarcomas, and lymphangiomas. To our knowledge, this case is the first description of hydrops fetalis caused by ganglioneuromas. We propose that multiple thoracic ganglioneuromas led to biventricular distal outflow tract obstruction and hydrops fetalis.

    Aim: To evaluate the incidence and associated factors of postoperative intense pain and haemodynamic changes during radiofrequency ablation of hepatocellular carcinoma. Materials and methods: A total of 123 consecutive hepatocellular carcinoma patients who underwent radiofrequency ablation were prospectively recruited. Patient factors, tumour characteristics, procedural factors, intraoperative haemodynamic changes, complications, postoperative events, laboratory values before and after ablation, and postoperative pain were evaluated. Postoperative pain was scored using a visual analogue scale after the procedure. Results: The mean age of the patients was 65.6 ± 9.6 years. In multiple logistic regression analysis, patients who underwent general anaesthesia [odds ratio (95% CI): 2.68 (1.23–5.81); p = 0.013] and had more postoperative nausea and vomiting episodes [3.10 (1.11–8.63); p = 0.036] were associated with intense pain. These findings remain robust after propensity score matching. For mean difference values between before and after RFA, higher in change in aspartate transaminase (p = 0.026), alanine transaminase (p = 0.016) and white blood cell count (p = 0.015), and lower in change in haemoglobin (p = 0.009) were also correlated with intense pain. There was no significant difference in haemodynamic changes between the general anaesthesia and local anaesthesia group during ablation. Conclusion: General anaesthesia, postoperative nausea and vomiting, and laboratory factors were associated with postoperative intense pain in patients who underwent radiofrequency ablation. Counselling and modification of analgesics should be considered in patients with related factors for intense pain

    The 3 phase 3 CHAMPION (Cangrelor vs Standard Therapy to Achieve Optimal Management of Platelet Inhibition) trials collectively demonstrated the safety of transitioning from cangrelor, a potent, parenteral rapidly-acting P2Y 12 inhibitor, to clopidogrel in patients who underwent percutaneous coronary intervention (PCI). However, variation in timing of therapy, site-specific binding, and drug half-lives may theoretically complicate switching to other oral P2Y 12 inhibitors. Since regulatory approval, limited data are available regarding the "real-world" safety and tolerability of transitioning to these more potent oral P2Y 12 antagonists. From November 2015 to January 2017, we evaluated the clinical profiles and efficacy and safety outcomes in cangrelor-treated patients who underwent PCI transitioned to clopidogrel (n = 42) or ticagrelor (n = 82) at a large, tertiary care center. Most patients receiving cangrelor underwent PCI with a drug-eluting stent for acute coronary syndrome via a radial approach in the background of unfractionated heparin. Stent thrombosis within 48 hours was rare and occurred in 1 patient treated with ticagrelor. Global Use of Strategies to Open Occluded Coronary Arteries-defined bleeding occurred in 20% of patients switched to ticagrelor and 29% of patients switched to clopidogrel, but none were severe or life-threatening. In conclusion, rates of stent thrombosis and severe/life-threatening bleeding were low and comparable with those identified in the CHAMPION program, despite use of more potent oral P2Y 12 inhibition.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available Introduction: Emergency department thoracotomy (EDT may serve as the last survival chance for patients who arrive at hospital in extremis. It is considered as an effective tool for improvement of traumatic patients’ outcome. The present study was done with the goal of assessing the outcome of patients who underwent EDT and its predictive factors. Methods: In the present study, medical charts of 50 retrospective and 8 prospective cases underwent emergency department thoracotomy (EDT were reviewed during November 2011 to June 2013. Comparisons between survived and died patients were performed by Mann-Whitney U test and the predictive factors of EDT outcome were measured using multivariate logistic regression analysis. P < 0.05 considered statistically significant. Results: Fifty eight cases of EDT were enrolled (86.2% male. The mean age of patients was 43.27±19.85 years with the range of 18-85. The mean time duration of CPR was recorded as 37.12±12.49 minutes. Eleven cases (19% were alive to be transported to OR (defined as ED survived. The mean time of survival in ED survived patients was 223.5±450.8 hours. More than 24 hours survival rate (late survived was 6.9% (4 cases. Only one case (1.7% survived to discharge from hospital (mortality rate=98.3%. There were only a significant relation between ED survival and SBP, GCS, CPR duration, and chest trauma (p=0.04. The results demonstrated that initial SBP lower than 80 mmHg (OR=1.03, 95% CI: 1.001-1.05, p=0.04 and presence of chest trauma (OR=2.6, 95% CI: 1.75-3.16, p=0.02 were independent predictive factors of EDT mortality. Conclusion: The findings of the present study showed that the survival rate of trauma patients underwent EDT was 1.7%. In addition, it was defined that falling systolic blood pressure below 80 mmHg and blunt trauma of chest are independent factors that along with poor outcome.

    Two patients with thoracic manifestations of hydatid disease (HD) are discussed; one patient had recurrent HD of the chest wall and the other, intrapulmonary HD after rupture and intrathoracic extension of an infradiaphragmatic cyst. At magnetic resonance (MR) imaging the manifestations of HD in the thorax are similar to previously reported MR findings in HD in the liver. The presence of a low signal intensity rim on T2 weighted images representing the cyst wall was confirmed. On T1 weighted images cysts with heterogeneous low and intermediate signal intensity contents and a relatively high signal intensity wall were seen. ''Folded parasitic membranes'' previously not described on MR were noted. Daughter cysts may have a low or high signal intensity depending on contents. Reactive changes in the lung may be quite marked compared with the liver, due to reaction to the parasite or simply because the lung is more easily compressed leading to secondary atelectasis.

    2015-01-01

    Respiratory and cardiac motion leads to image degradation in Positron Emission Tomography (PET), which impairs quantification. In this book, the authors present approaches to motion estimation and motion correction in thoracic PET. The approaches for motion estimation are based on dual gating and mass-preserving image registration (VAMPIRE) and mass-preserving optical flow (MPOF). With mass-preservation, image intensity modulations caused by highly non-rigid cardiac motion are accounted for. Within the image registration framework different data terms, different variants of regularization and parametric and non-parametric motion models are examined. Within the optical flow framework, different data terms and further non-quadratic penalization are also discussed. The approaches for motion correction particularly focus on pipelines in dual gated PET. A quantitative evaluation of the proposed approaches is performed on software phantom data with accompanied ground-truth motion information. Further, clinical appl...

    In order to determine the thoracic manifestations of severe ovarian hyperstimulation syndrome, the medical records and available images of 771 patients who had received gonadotropins to induce superovulation, were reviewed. In 22 patients (3%) severe hyperstimulation syndrome was diagnosed clinically and confirmed with ultrasonography (US). Pleural effusion occurred in five of these (23%), one of whom required thoracentesis. Atelectasis and internal jugular vein thrombosis developed in one patient, and ventilation-perfusion mismatch occurred in another. The study concluded that respiratory distress in patients with ovarian hyperstimulation syndrome was most likely due to lung restriction. Pulmonary manifestations formed an important part of this syndrome, and radiologic input were considered necessary for assessment, monitoring and management. 10 refs., 2 figs., 1 tab.

    Benchmarking entails continuous comparison of efficacy and quality among products and activities, with the primary objective of achieving excellence. To analyze the results of benchmarking performed in 2013 on clinical practices undertaken in 2012 in 17 Spanish thoracic surgery units. Study data were obtained from the basic minimum data set for hospitalization, registered in 2012. Data from hospital discharge reports were submitted by the participating groups, but staff from the corresponding departments did not intervene in data collection. Study cases all involved hospital discharges recorded in the participating sites. Episodes included were respiratory surgery (Major Diagnostic Category 04, Surgery), and those of the thoracic surgery unit. Cases were labelled using codes from the International Classification of Diseases, 9th revision, Clinical Modification. The refined diagnosis-related groups classification was used to evaluate differences in severity and complexity of cases. General parameters (number of cases, mean stay, complications, readmissions, mortality, and activity) varied widely among the participating groups. Specific interventions (lobectomy, pneumonectomy, atypical resections, and treatment of pneumothorax) also varied widely. As in previous editions, practices among participating groups varied considerably. Some areas for improvement emerge: admission processes need to be standardized to avoid urgent admissions and to improve pre-operative care; hospital discharges should be streamlined and discharge reports improved by including all procedures and complications. Some units have parameters which deviate excessively from the norm, and these sites need to review their processes in depth. Coding of diagnoses and comorbidities is another area where improvement is needed. Copyright © 2015 SEPAR. Published by Elsevier Espana. All rights reserved.

    The study investigated the association between the location of transposed ovaries and posttreatment ovarian function in patients with early cervical cancer (IB1-IIA) who underwent radical hysterectomy and ovarian transposition with or without adjuvant therapies. Retrospective medical records were reviewed to enroll the patients with early cervical cancer who underwent ovarian transposition during radical hysterectomy at Samsung Medical Center between July 1995 and July 2012. Serum follicle-stimulating hormone (FSH) level was used as a surrogate marker for ovarian function. Twenty-one patients were enrolled. The median age and body mass index (BMI) were 31 years (range, 24-39 years) and 21.3 kg/m² (range, 17.7-31.2 kg/m²), respectively. The median serum FSH level after treatment was 7.9 mIU/mL (range, 2.4-143.4 mIU/mL). The median distance from the iliac crest to transposed ovaries on erect plain abdominal x-ray was 0.5 cm (range, -2.7 to 5.2 cm). In multivariate analysis, posttreatment serum FSH levels were significantly associated with the location of transposed ovaries (β = -8.1, P = 0.032), concurrent chemoradiation (CCRT) as an adjuvant therapy (β = 71.08, P = 0.006), and BMI before treatment (underweight: β = -59.93, P = 0.05; overweight: β = -40.62, P = 0.041). Location of transposed ovaries, adjuvant CCRT, and BMI before treatment may be associated with ovarian function after treatment. We suggest that ovaries should be transposed as highly as possible during radical hysterectomy to preserve ovarian function in young patients with early cervical cancer who might be a candidate for adjuvant CCRT and who have low BMI before treatment.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    The aim of this study was to evaluate nutritional status in children who underwent hematopoietic stem cell transplant compared with a healthy control group. A secondary aim was to utilize mid-upper arm circumference as a measure of nutritional status in these groups of children. Our study group included 40 children (18 girls, 22 boys) with mean age of 9.2 ± 4.6 years (range, 2-17 y) who underwent hematopoietic stem cell transplant. Our control group consisted of 20 healthy children (9 girls, 11 boys). The children were evaluated at admission to the hospital and followed regularly 3, 6, 9, and 12 months after discharge from the hospital. In the study group, 27 of 40 patients (67.5%) received nutritional support during hematopoietic stem cell transplant, with 15 patients (56%) receiving enteral nutrition, 6 (22%) receiving total parenteral nutrition, and 6 (22%) receiving enteral and total parenteral nutrition. Chronic malnutrition rate in the study group was 47.5% on admission to the hospital, with the control group having a rate of 20%. One year after transplant, the rate decreased to 20% in the study group and 5% in the control group. The mid-upper arm circumference was lower in children in the study group versus the control group at the beginning of the study (P groups at follow-up examinations (P > .05). During follow-up, all anthropometric measurements increased significantly in both groups. Monitoring nutritional status and initiating appropriate nutritional support improved the success of hematopoietic stem cell transplant and provided a more comfortable process during the transplant period. Furthermore, mid-upper arm circumference is a more sensitive, useful, and safer parameter that can be used to measure nutritional status of children who undergo hematopoietic stem cell transplant.

    This study aims to identify independent factors correlating to an increased risk of perioperative stroke during thoracic endovascular aortic repair (TEVAR). A prospective maintained TEVAR database, medical records, and imaging studies of 300 patients (205 men; median age of all, 66 years, range 21-89), who underwent TEVAR between March 1997 and February 2011, were reviewed. Preoperative CT data sets were reviewed by two experienced radiologists with focus on the atheroma burden in the aortic arch (grade I, normal, to grade V, ulcerated or pedunculated atheroma). Aortic arch geometry (arch types I-III) was documented. Further parameters included in the univariate analysis were age, gender, urgency of repair, duration of procedure, adenosine-induced cardiac arrest or rapid pacing, proximal landing zone, left subclavian artery (LSA) coverage, and number of stent grafts. Multivariate logistic regression analysis was performed to assess the independent correlations of potential risk factors. Atherosclerotic aneurysm was the most common pathology (44%). One hundred and fifty-four of our patients (51%) were treated under urgent or emergent conditions. Seventeen percent of all patients had significant arch atheroma (grade IV or V), and 43% had a steep type III aortic arch. The perioperative stroke was 4% (12 patients; median age, 73 years, range 31-78). Two strokes were lethal (0.7%). All strokes were classified as embolic based on imaging characteristics. In eight patients, strokes were located in the left cerebral hemisphere (seven of them in the anterior and one in the posterior circulation). Four stroke patients (one in the left posterior circulation) underwent LSA coverage without revascularization. Three stroke patients had severe arch atheroma grade V. Five patients suffering stroke were recognized to have a type III aortic arch. Strokes were equally distributed between zones 0-2 vs. 3-4 (n = 6 each, 5 vs. 3.3%). The highest incidence was found in zone 1 (11

    The purpose of the study was to describe a unique type of low-energy traumatic pediatric thoracic spinal cord injury without radiographic abnormality (SCIWORA) after a back bend during dance practice and analyze the trauma mechanisms and treatment protocols. This was a retrospective case series from September 2007 to August 2016. The study was conducted at a tertiary medical center in Beijing, China (Xuanwu Hospital, China International Neuroscience Institute [China-INI], Capital Medical University). A total of 12 pediatric patients who had a clear traumatic history after back bend movements and had been diagnosed with thoracic SCIWORA were included. Clinical and imaging data were obtained for each patient. The follow-up data was analyzed. The traumatic mechanisms were investigated by analyzing the patients' medical history, spinal diffusion tensor imaging (DTI) and fiber tractography data. Of the 12 patients, 11 (91.7%) were younger than 8 years old. The mean age of the patients was 6.6 years. All patients had a clear traumatic history of severe thoracic spinal cord injury after performing back bend movements. The mean follow-up time was 36.5 months. During the follow-up period, 1 patient (8.3%) recovered completely, and 11 patients (91.7%) had unfavorable prognoses, including 4 (33.3%) with incomplete recovery and 7 (58.3%) with no change. Two patients underwent spinal DTI, which showed rupture of the nerve fiber bundle in the section of the injury. Back bend movements performed during dance practice may cause pediatric thoracic SCIWORA, particularly in children younger than 8 years old. We suggest that the mechanism of primary injury is the longitudinal distraction of the thoracic spine during back bend movements, which leads to violent distraction of the spinal cord and blunt injury of nerve axons, nerve cells, and small vessels. Spinal DTI may facilitate the diagnosis and prognostic evaluation of SCIWORA.

    The hybrid assistive limb (HAL) is a wearable robot suit that assists in voluntary control of knee and hip joint motion by detecting bioelectric signals on the surface of the skin with high sensitivity. HAL has been reported to be effective for functional recovery in motor impairments. However, few reports have revealed the utility of HAL for patients who have undergone surgery for thoracic ossification of the posterior longitudinal ligament (thoracic OPLL). Herein, we present a postoperative thoracic OPLL patient who showed remarkable functional recovery after training with HAL. A 63-year-old woman, who could not walk due to muscle weakness before surgery, underwent posterior decompression and fusion. Paralysis was re-aggravated after the initial postoperative rising. We diagnosed that paralysis was due to residual compression from the anterior lesion and microinstability after posterior fixation, and prescribed bed rest for a further 3 weeks. The incomplete paralysis gradually recovered, and walking training with HAL was started on postoperative day 44 in addition to standard physical therapy. The patient underwent 10 sessions of HAL training until discharge on postoperative day 73. Results of a 10-m walk test were assessed after every session, and the patient's speed and cadence markedly improved. At discharge, the patient could walk with 2 crutches and no assistance. Furthermore, no adverse events associated with HAL training occurred. HAL training for postoperative thoracic OPLL patients may enhance improvement in walking ability, even if severe impairment of ambulation and muscle weakness exist preoperatively.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and⁄or anatomical anomalies. To determine the motor and anatomical causes of dysphagia. A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, nonpropagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14%, diverticula in 14% and stenosis in 7

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change

    Three models of care are described, including two models of multidisciplinary care for thoracic malignancies. The pros and cons of each model are discussed, the evidence supporting each is reviewed, and the need for more (and better) research into care delivery models is highlighted. Key stakeholders in thoracic oncology care delivery outcomes are identified, and the need to consider stakeholder perspectives in designing, validating and implementing multidisciplinary programs as a vehicle for quality improvement in thoracic oncology is emphasized. The importance of reconciling stakeholder perspectives, and identify meaningful stakeholder-relevant benchmarks is also emphasized. Metrics for measuring program implementation and overall success are proposed.

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients' responses were graded according to the Miller-Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR ( P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens ( P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

  9. Neural progenitor cells but not astrocytes respond distally to thoracic spinal cord injury in rat models

    Full Text Available Traumatic spinal cord injury (SCI is a detrimental condition that causes loss of sensory and motor function in an individual. Many complex secondary injury cascades occur after SCI and they offer great potential for therapeutic targeting. In this study, we investigated the response of endogenous neural progenitor cells, astrocytes, and microglia to a localized thoracic SCI throughout the neuroaxis. Twenty-five adult female Sprague-Dawley rats underwent mild-contusion thoracic SCI (n = 9, sham surgery (n = 8, or no surgery (n = 8. Spinal cord and brain tissues were fixed and cut at six regions of the neuroaxis. Immunohistochemistry showed increased reactivity of neural progenitor cell marker nestin in the central canal at all levels of the spinal cord. Increased reactivity of astrocyte-specific marker glial fibrillary acidic protein was found only at the lesion epicenter. The number of activated microglia was significantly increased at the lesion site, and activated microglia extended to the lumbar enlargement. Phagocytic microglia and macrophages were significantly increased only at the lesion site. There were no changes in nestin, glial fibrillary acidic protein, microglia and macrophage response in the third ventricle of rats subjected to mild-contusion thoracic SCI compared to the sham surgery or no surgery. These findings indicate that neural progenitor cells, astrocytes and microglia respond differently to a localized SCI, presumably due to differences in inflammatory signaling. These different cellular responses may have implications in the way that neural progenitor cells can be manipulated for neuroregeneration after SCI. This needs to be further investigated.

    Are the concentrations of five criteria air pollutants associated with probabilities of biochemical pregnancy loss and intrauterine pregnancy in women? Increased concentrations of ambient particulate matter (PM10), nitrogen dioxide (NO2), carbon monoxide (CO) during controlled ovarian stimulation (COS) and after embryo transfer were associated with a decreased probability of intrauterine pregnancy. Exposure to high ambient air pollution was suggested to be associated with low fertility and high early pregnancy loss in women. Using a retrospective cohort study design, we analysed 6621 cycles of 4581 patients who underwent one or more fresh IVF cycles at a fertility centre from January 2006 to December 2014, and lived in Seoul at the time of IVF treatment. To estimate patients' individual exposure to air pollution, we computed averages of hourly concentrations of five air pollutants including PM10, NO2, CO, sulphur dioxide (SO2) and ozone (O3) measured at 40 regulatory monitoring sites in Seoul for each of the four exposure periods: period 1 (start of COS to oocyte retrieval), period 2 (oocyte retrieval to embryo transfer), period 3 (embryo transfer to hCG test), and period 4 (start of COS to hCG test). Hazard ratios (HRs) from the time-varying Cox-proportional hazards model were used to estimate probabilities of biochemical pregnancy loss and intrauterine pregnancy for an interquartile range (IQR) increase in each air pollutant concentration during each period, after adjusting for individual characteristics. We tested the robustness of the result using generalised linear mixed model, accounting for within-woman correlation. Mean age of the women was 35 years. Average BMI was 20.9 kg/m2 and the study population underwent 1.4 IVF cycles on average. Cumulative pregnancy rate in multiple IVF cycles was 51.3% per person. Survival analysis showed that air pollution during periods 1 and 3 was generally associated with IVF outcomes. Increased NO2 (adjusted HR = 0.93, 95% CI

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

  14. Thoracic splenosis as a differential diagnosis of juxtapleural nodules

    Directory of Open Access Journals (Sweden)

    B. Lopes

    2014-01-01

    Full Text Available Thoracic splenosis is rare and consists of ectopic implantation of splenic tissue into the chest after concomitant thoracic and abdominal trauma with diaphragm injury. It occurs in about 18% of cases of splenic ruptures. In almost all cases, diagnosis is given incidentally once patients are usually asymptomatic. Thoracic splenosis should be considered as a differential diagnosis in all patients with history of trauma presenting with juxtapleural nodules in chest computed tomography. However, malignant conditions should be ruled out firstly. Biopsy is not essential for the diagnosis once nuclear medicine can confirm splenosis in patients with pertinent history of trauma and suggestive tomographic image. We present a typical case of thoracic splenosis whose diagnosis was made by nuclear medicine and no invasive procedures were required.

An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, Panesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

    Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber. Sampling performance was evaluated against conventional thoracic penetration. Three of the tested samplers performed well, when sampling the thoracic aerosol at nominal flow rate and two others performed well at optimized flow rate. The limit of flow rate optimization was found when using cyclone samplers. © The Author 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

    Thoracic wounding has been a relatively common presentation of military wounds throughout modern conflict. When civilian casualties are included the incidence has remained constant at around 10%, although the frequency and severity of wounds to combatants has been altered by modern body armour. Whilst thoracic injury has a high initial mortality on the battlefield, those surviving to reach hospital frequently have injuries that only require simple management. In addition to penetrating ballistic injury, blunt chest trauma frequently occurs on operations as a result of road traffic collisions or tertiary blast injury. The physiological impact of thoracic wounds, however, is often great and survivors often require intensive care management and, where available, complex strategies to ensure oxygenation and carbon dioxide removal. This review examines the incidence and patterns of thoracic trauma and looks at therapeutic options for managing these complex cases.

Retrospective comparison between gadofosveset trisodium and gadobenate dimeglumine steady state magnetic resonance angiography (SS-MRA of the thoracic vasculature at 1.5T using signal-to-noise ratio (SNR and vessel edge sharpness (ES as markers of image quality. Materials and Methods. IRB approval was obtained. Twenty separate patients each underwent SS-MRA using high-resolution 3D ECG-triggered coronal IR-TFE at 1.5T approximately 3-4 minutes following 10 or 15 mL gadofosveset or 20 mL gadobenate. ROIs were placed in the right atrium, left ventricle, left atrium, ascending aorta, descending aorta, and right pulmonary artery to estimate SNR. Vessel ES was estimated as 20–80% rise distances from line intensity profiles in the left pulmonary vein, ascending aorta, and descending aorta. Data were analyzed using nonpaired Student’s t-test (threshold for significance set at P<0.05. Results. There was no significant difference in mean SNR for the gadofosveset or gadobenate groups (P values: 0.14 to 0.85. There was no significant difference in mean vessel ES for gadofosveset and gadobenate groups (P values: 0.17 to 0.78. Conclusion. High quality thoracic SS-MRA can be achieved with gadobenate dimeglumine, similar to that achieved with the blood pool agent gadofosveset trisodium provided that imaging is initiated quickly (3-4 min after contrast injection.

    Full Text Available Abstract Background The purpose of this study was to test the hypothesis that direct vertebral derotation by pedicle screws (PS causes hypokyphosis of the thoracic spine in adolescent idiopathic scoliosis (AIS patients, using computer simulation. Methods Twenty AIS patients with Lenke type 1 or 2 who underwent posterior correction surgeries using PS were included in this study. Simulated corrections of each patient’s scoliosis, as determined by the preoperative CT scan data, were performed on segmented 3D models of the whole spine. Two types of simulated extreme correction were performed: 1 complete coronal correction only (C method and 2 complete coronal correction with complete derotation of vertebral bodies (C + D method. The kyphosis angle (T5-T12 and vertebral rotation angle at the apex were measured before and after the simulated corrections. Results The mean kyphosis angle after the C + D method was significantly smaller than that after the C method (2.7 ± 10.0° vs. 15.0 ± 7.1°, p  Conclusions In the 3D simulation study, kyphosis was reduced after complete correction of the coronal and rotational deformity, but it was maintained after the coronal-only correction. These results proved the hypothesis that the vertebral derotation obtained by PS causes hypokyphosis of the thoracic spine.

    To assess the value of adding a reformatted computed tomography (CT) rib series to transversely reconstructed CT imaging in the evaluation of rib fractures in patients with suspected traumatic thoracic injuries. One hundred consecutive patients with suspected traumatic thoracic injuries underwent 128-section multi-detector row CT. Transverse CT images with 5-mm-thick sections were reconstructed and rib series were reformatted using isotropic vogel data. Three independent radiologists, who were blinded to the data, interpreted the CT scans at 2 sessions with a 4-week interval between the sessions. Only transverse CT images were reviewed at the first session. At the second session, the CT images were reviewed along with the reformatted CT rib series. The following parameters were analyzed: receiver operating characteristic (Roc) curve, pairwise comparisons of Roc curves, sensitivity, specificity, positive predictive value, and negative predictive value. There were 153 rib fractures in 29 patients. The level of the area under the Roc curve, Az improved for all observers. The diagnostic sensitivity and specificity of each observer tended to improve in the second session. The mean confidence scores for all observers of patients with rib fractures improved significantly in the second session. A reformatted CT rib series together with transverse CT scan is useful for the evaluation of rib fracture.

    The purpose of this study is to verify the usefulness of the quantification of aortic wall involvement by enhanced computed tomography (CT). One-hundred thirteen Japanese patients underwent two enhanced CT of the descending thoracic aorta at intervals. We sliced the descending thoracic aorta continuously from the level of the tracheal bifurcation with 1 cm intervals, and we defined aortic wall volume (AWV) (cm 3 ) as the sum of a 7-slice area of aortic wall involving calcification. The average of AWV increased from 7.95±2.92 cm 3 to 8.70±2.98 cm 3 . The developmental rate of AWV (ΔAWV) was 0.270±0.281 cm 3 /year. ΔAWV did not have a significant correlation with any risk factor at the baseline. ΔAWV had significant correlation with total cholesterol, (LDL-C) low-density lipoprotein cholesterol and LDL-C/(HDL-C) high-density lipoprotein cholesterol ratio at the follow-up, and by multivariate analysis with only the LDL-C/HDL-C ratio. ΔAWV was not correlated with the intake status of hypoglycemic, antihypertensive or lipid-lowering drugs. The cut-off level of total cholesterol with the most significant odds ratio for progression of aortic wall was 190 mg/dl, and that of LDL-C was 130 mg/dl. This method proved to be useful for the non-invasive assessment of aortic wall thickness. (author)

    This retrospective study was carried out to evaluate the indications for and outcomes of the hemiclamshell (HCS) approach (longitudinal partial sternotomy with antero-lateral thoracotomy) in patients undergoing mass resection in thoracic surgery. All patients (50) who underwent a HCS procedure in our department, between July 1996 and July 2005, were studied retrospectively, analyzing the indications, morbidity and outcome (pain, neurological or shoulder defects, mortality) at one month and one year. The main indications were apical tumours (38%), tumours of the cervicothoracic junction (46%) and chest wall (10%), and 'bulky' tumours (6%). One-month mortality was 6%. Two patients suffered from a chylothorax and one from phrenic paralysis. The postoperative analgesic requirements were similar to those after other thoracic surgery approaches. Twelve percent of patients suffered pain at one month and 6% at one year. Shoulder dysfunction was observed in 10% of patients at one month and 6% at one year. In conclusion, the HCS surgical approach was associated with an uncomplicated postoperative course. This anterior approach is suitable for apical tumours, tumours of the cervicothoracic junction and 'bulky' lung tumours, providing good access for control of the large vessels and radical mediastinal clearance.

    The objective of this study was to evaluate the performance of 3 thoracic surgery centres using the Eurolung risk models for morbidity and mortality. This was a retrospective analysis performed on data collected from 3 academic centres (2014-2016). Seven hundred and twenty-one patients in Centre 1, 857 patients in Centre 2 and 433 patients in Centre 3 who underwent anatomical lung resections were analysed. The Eurolung1 and Eurolung2 models were used to predict risk-adjusted cardiopulmonary morbidity and 30-day mortality rates. Observed and risk-adjusted outcomes were compared within each centre. The observed morbidity of Centre 1 was in line with the predicted morbidity (observed 21.1% vs predicted 22.7%, P = 0.31). Centre 2 performed better than expected (observed morbidity 20.2% vs predicted 26.7%, P models were successfully used as risk-adjusting instruments to internally audit the outcomes of 3 different centres, showing their applicability for future quality improvement initiatives. © The Author(s) 2018.

    The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD) reports outstanding results for lung and esophageal cancer resection. However, a major weakness of the GTSD has been the lack of validation of this voluntary registry. The purpose of this study was to perform an external, independent audit to assess the accuracy of the data collection process and the quality of the database. An independent firm was contracted to audit 5% of sites randomly selected from the GTDB in 2011. Audits were performed remotely to maximize the number of audits performed and reduce cost. Auditors compared lobectomy cases submitted to the GTSD with the hospital operative logs to evaluate completeness of the data. In addition, 20 lobectomy records from each site were audited in detail. Agreement rates were calculated for 32 individual data elements, 7 data categories pertaining to patient status or care delivery, and an overall agreement rate for each site. Six process variables were also evaluated to assess best practice for data collection and submission. Ten sites were audited from the 222 participants. Comparison of the 559 submitted lobectomy cases with operative logs from each site identified 28 omissions, a 94.6% agreement rate (discrepancies/site range, 2 to 27). Importantly, cases not submitted had no mortality or major morbidity, indicating a lack of purposeful omission. The aggregate agreement rates for all categories were greater than 90%. The overall data accuracy was 94.9%. External audits of the GTSD validate the accuracy and completeness of the data. Careful examination of unreported cases demonstrated no purposeful omission or gaming. Although these preliminary results are quite good, it is imperative that the audit process is refined and continues to expand along with the GTSD to insure reliability of the database. The audit results are currently being i
