    Background Surgical treatment is thought to be the most effective strategy for multiple small nodules. However, in general, one-stage bilateral resection is not recommended due to its highly invasive nature. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2009 and September 2014 in a single institution were retrospectively reviewed. Results Simultaneous bilateral pulmonary resection by conventional video-assisted thoracic surgery (VATS) was undertaken in 29 patients. Ground glass opacity (GGO) accounted for 71.9% (46/64) of total lesions, including 26 pure GGO and 20 mixed GGO lesions. One case underwent bilateral lobectomy that was complicated by postoperative dyspnea. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 16 and 12 cases, respectively, and most of these cases had uneventful postoperative courses. There was no significant difference with regard to postoperative complications (P=0.703), duration of use of chest drains (P=0.485), between one- and two-stage groups. Mean postoperative follow-up in cases of primary lung cancer was 31.4 (range, 10–51) months. There was neither recurrence nor deaths at final follow-up. Conclusions Single-stage bilateral surgery in selected cases with synchronous bilateral multiple nodules (SBMNs) is feasible and associated with satisfactory outcomes. PMID:27076942

    Full Text Available Objective. Improve the effectiveness of surgical treatment in patients with bilateral destructive pulmonary tuberculosis by mini-invasive resection and collapse therapy. Materials and Methods: Retrospective analysis of 222 patients’ cards with bilateral destructive pulmonary tuberculosis who were treated in the period from 1995 to 2014 in the thoracic department of Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology". Patients were divided into 2 groups: basic (111 patients who underwent mini-invasive surgery and control (111 patients, who underwent standard surgical approach. The distribution of patients in investigated groups was representative by the majority of parameters. Results and discussion. The average duration of simultaneous bilateral VATS lung resections was 1,90 ± 0,12 hour, standard thoracotomies - 2,13 ± 0,19 per hour, estimated blood loss was 234±5,20ml and 433±3,70ml respectively. The average postoperative time in-patient was 52,40±2,63 days in basic and 80,10±3,58 days in the control group. Number of postoperative complications after lung resection with VATS was significantly lower (1.6 times, as compared with standard surgical approach. Volume of blood loss less than 400 ml was 93,40±3,20% in basic and 72,60±4,80% in the control group, the amount of intraoperative complications reduced by 2.2 times. Complete clinical response (decontamination and closing of cavities have been achieved in patients of the basic group by 1.6 times more often. Conclusions: For patients with bilateral pulmonary tuberculosis to perform mini-invasive surgical approach is the best option. Mini-invasive interventions with VATS due to its good abilities to visualize tissues and anatomical structures may significantly decrease the amount of intraoperative blood and plasma loss in the first postoperative day. It leads to the stabilization of tuberculosis process in the contralateral lung, responsible for

    Full Text Available The incidence of human epidermal growth factor receptor 2 (Her-2 mutations in lung adenocarcinoma is approximately 3%; however, its significance in the management of these lung cancers remains under investigation. We describe an incidental but unique opportunity to evaluate the response to treatment with herceptin in a patient with bilateral synchronous lung primaries in conjunction with breast carcinoma. Interval imaging following surgical resection of the squamous cell carcinoma while on herceptin treatment delineated the radiological regression of the Her-2 positive lung adenocarcinoma. We feel that this case highlights the potential role for herceptin treatment in Her-2 positive lung adenocarcinomas and demonstrates the importance of screening for these mutations.

    During the last decades lung cancer is the leading cause of death worldwide for both sexes. Even though cigarette smoking has been proved to be the main causative factor, many other agents (e.g., occupational exposure to asbestos or heavy metals, indoor exposure to radon gas radiation, particulate air pollution) have been associated with its development. Recently screening programs proved to reduce mortality among heavy-smokers although establishment of such strategies in everyday clinical practice is much more difficult and unknown if it is cost effective compared to other neoplasms (e.g., breast or prostate cancer). Adding severe comorbidities (coronary heart disease, COPD) to the above reasons as cigarette smoking is a common causative factor, we could explain the low surgical resection rates (approximately 20-30%) for lung cancer patients. Three clinical guidelines reports of different associations have been published (American College of Chest Physisians, British Thoracic Society and European Respiratory Society/European Society of Thoracic Surgery) providing detailed algorithms for preoperative assessment. In the current mini review, we will comment on the preoperative evaluation of lung cancer patients. PMID:24672690

    Full Text Available We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.

    Full Text Available Leptomeningeal carcinomatosis is rare, and its precise incidence is unknown. It is associated with a wide spectrum of solid and hematological malignancies. To complicate its diagnosis, the clinical presentation of leptomeningeal carcinomatosis can be variable. We report a case of a 38-year-old male with bilateral facial nerve paralysis as first presentation of lung adenocarcinoma. To our knowledge, this is the only case describing bilateral facial nerve palsy as the first and only manifestation of lung adenocarcinoma.

    2012-08-15

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    Aim: To observe the changes in thymocyte and its microenvironment in aged mice after bilateral testicular resection.Methods: In male old mice, at the 25th day after testicular resection, the peripheral blood and thymus were collected. Blood and thymus suspension smears were prepared for quantitative histochemistry and immunohistochemistry study under light and electron microscopes. Results: In testes resected mice the size and the weight of thymus were markedly increased. The demarcation between cortex and medulla was clear. The cortex was thickened and the cell density was increased. The ratio of cortex/medulla stereometry was increased. The total cell count, thymocyte count,the percentage of acid α-naphthyl acetate esterase (ANAE) positive thymocytes, nonlymphocytes and the rosette formation of macrophages and thymocytes were all increased. The thymocytes surrounded closely to the light thymic epithelial cells, dendritic cells or macrophages. The lymphocytes, particularly the ANAE positive lymphocytes of peripheral blood were increased. Conclusion: After bilateral testicular resection, the thymus of aged male mice showed morphological regeneration and the thymocytes and its microenvironment appeared to be definitely improved. It is suggested that testicular resection may improve immune function.

    2015-01-01

    Full Text Available Adrenal incidentalomas are found incidentally during a radiologic examination performed for indications other than an adrenal disease, and 15% of them are bilateral adrenal masses. This study describes a 51-year-old male smoker patient admitted with diabetes mellitus. An abdominal ultrasonography performed due to his anemia revealed bilateral adrenal masses. His chest X-ray showed abnormal 10 cm opacity at the right upper lung, and brain, thorax, and abdomen CT scans showed multiple lesions compatible with lung cancer metastases. The pathological examination of the transthoracic lung biopsy specimen was consistent with lung adenocarcinoma. Findings in this patient indicate that, in middle aged patients with bilateral adrenal mass and a history or finding of any malignancy, the first diagnosis which should be considered is adrenal metastasis, and confirming the diagnosis by adrenal biopsy may be useless. Furthermore, screening all smoking patients by chest X-ray or thoracic CT for lung cancer may not be accepted as a routine procedure, but in smokers admitted to a hospital due to signs and symptoms attributed to a pulmonary disease, at least a chest X-ray should be requested.

    Micro-invasive thoracic surgery, especially represented by video-assisted thoracic surgery (VATS), has become the mainstream of lung cancer resection. Traditional multi-portal VATS techniques, including four-port, three-port, and two-port VATS, have been widely used to perform nearly all kinds of lung cancer resections. However, how to make lung cancer resection less invasive is always the subject that all thoracic surgeons never stop pursuing. Compared with multi-portal VATS, uniportal VATS causes less postoperative pain and paresthesia because only one small incision is made and one intercoastal space is involved. In recent years, good clinical results have been obtained from uniportal VATS in lung cancer resections. In this paper, we'd like to present a brief summary about the progresses made in the application of uniportal VATS in lung cancer resection. Uniportal VATS is a sublimation of micro-invasive lung cancer resection.

    2010-08-01

    Thoracic surgery that requires resection of a portion of lung or of a whole lung profoundly alters the mechanical and fluid dynamic setting of the lung-chest wall coupling, as well as the water balance in the pleural space and in the remaining lung. The most frequent postoperative complications are of a respiratory nature, and their incidence increases the more the preoperative respiratory condition seems compromised. There is an obvious need to identify risk factors concerning mainly the respiratory function, without neglecting the importance of other comorbidities, such as coronary disease. At present, however, a satisfactory predictor of postoperative cardiopulmonary complications is lacking; postoperative morbidity and mortality have remained unchanged in the last 10 years. The aim of this review is to provide a pathophysiologic interpretation of the main respiratory complications of a respiratory nature by relying on new concepts relating to lung fluid dynamics and mechanics. New parameters are proposed to improve evaluation of respiratory function from pre- to the early postoperative period when most of the complications occur.

    Full Text Available Breast and lung cancers are the most common primary neoplasms to manifest with choroidal metastases. The incidence of choroidal metastases from metastatic lung cancer was reported to be 2–6.7%. We report a case of bilateral choroidal metastasis from non-small cell lung cancer. A 59-year-old Caucasian female patient, never a smoker, was diagnosed with stage IV lung adenocarcinoma metastatic to the pleura, bones, and the brain. Her initial scan of the chest showed innumerable soft tissue nodules and mediastinal adenopathy compatible with metastatic disease. Her initial brain MRI showed numerous small enhancing lesions consistent with extensive disease. Unfortunately, during her follow-up visits, she presented with bulge on her left eye. Simultaneously, her follow-up chest scan showed increase in the size of the lung nodules. She continued to have a reasonable performance status at that time, except for mild increase in her dyspnea. The choroidal metastases require a multidisciplinary care and should be among the differential patients with malignancy who present with ocular symptoms.

    The aim of the study was to determine in human patients the effect of lung resection on lung compliance and on pleuro-pulmonary fluid balance. Pre and post-operative values of compliance were measured in anesthetized patients undergoing resection for lung cancer (N=11) through double-lumen bronchial intubation. Lung compliance was measured for 10-12 cm H2O increase in alveolar pressure from 5 cm H2O PEEP in control and repeated after resection. No air leak was assessed and pleural fluid was collected during hospital stay. A significant negative correlation (r(2)=0.68) was found between compliance at 10 min and resected mass. Based on the pre-operative estimated lung weight, the decrease in compliance following lung resection exceeded by 10-15% that expected from resected mass. Significant negative relationships were found by relating pleural fluid drainage flow to the remaining lung mass and to post-operative lung compliance. Following lung re-expansion, data suggest a causative relationship between the decrease in compliance and the perturbation in pleuro-pulmonary fluid balance.

    Yang, Fan; Wang, Jun

    2015-10-01

    Lobectomy with lymph node dissection has long been the standard surgical procedure for non-small cell lung cancer. However, the increased identification of smaller and smaller and even more indolent tumors by advanced imaging screening rekindled the interest of sublobar resection. Still, existing evidence only supports sublobar resection for radiologically or pathologically "very-early" stage tumors or high-risk patients. Ongoing randomized controlled trials in America, Japan and Europe will address the issue of "radical" application of sublobar resection, as well as an elderly patient trial for "compromized" application initiated by us. These efforts will delineate the utility of sublobar resection in patients with non-small cell lung cancer.

    Abstract The aim of the present study was to determine the distribution of lung blood in a modified bilateral Glenn procedure designed in our institute with lung perfusion scintigraphy. Sixteen consecutive patients who underwent modified bilateral Glenn operation from 2011 to 2014 were enrolled in the study. The control group consisted of 7 patients who underwent bidirectional Glenn shunt. Radionuclide lung perfusion scintigraphy was performed using Tc-99m-macro aggregated albumin (MAA) in all patients. For the patients in modified bilateral Glenn group, the time at which the radioactivity accumulation peaked did not differ significantly between the right and left lung field (t = 0.608, P = 0.554). The incidence of perfusion abnormality in each lung lobe also did not differ significantly (P = 0.426 by Fisher exact test). The radioactive counts were higher in the right lung than in the left lung, but the difference was not statistically significant (t = 1.502, P = 0.157). Radioactive perfusion in the lower lung field was significantly greater than that in the upper field (t = 4.368, P lung to that in left lung was significantly lower in the modified bilateral Glenn group (t = 3.686, P = 0.002). Lung perfusion scintigraphy confirmed the benefit of the modified bilateral Glenn shunt with regard to more balanced blood perfusion in both lungs. PMID:27661042

    Introduction: In recent years an increasing number of lung resections are being done because of the rising prevalence of lung cancer that occurs mainly in patients with limited lung function, what is caused with common etiologic factor - smoking cigarettes. Objective: To determine how big the loss of lung function is after surgical resection of lung of different range. Methods: The study was done on 58 patients operated at the Clinic for thoracic surgery KCU Sarajevo, previously treated at the Clinic for pulmonary diseases “Podhrastovi” in the period from 01.06.2012. to 01.06.2014. The following resections were done: pulmectomy (left, right), lobectomy (upper, lower: left and right). The values of postoperative pulmonary function were compared with preoperative ones. As a parameter of lung function we used FEV1 (forced expiratory volume in one second), and changes in FEV1 are expressed in liters and in percentage of the recorded preoperative and normal values of FEV1. Measurements of lung function were performed seven days before and 2 months after surgery. Results: Postoperative FEV1 was decreased compared to preoperative values. After pulmectomy the maximum reduction of FEV1 was 44%, and after lobectomy it was 22% of the preoperative values. Conclusion: Patients with airway obstruction are limited in their daily life before the surgery, and an additional loss of lung tissue after resection contributes to their inability. Potential benefits of lung resection surgery should be balanced in relation to postoperative morbidity and mortality. PMID:25568542

    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.

    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.

    Bilateral resections of the superficial masseter, posterior temporal, and anterior digastric muscles of rats were done to determine their effects on mandibular growth. The macroscopic findings support the functional matrix theory of mandibular growth. The analysis of body weight and the statistical two-way analysis of variance done suggest that malnutrition was the main factor that caused the mandibles of rats in the experimental groups of remain undersized.

    Introduction: In recent years there has been increase in the number of patients who need thoracic surgery – first of all different types of pulmonary resection because of primary bronchial cancer, and very often among patients whose lung function is impaired due to different degree of bronchial obstruction so it is necessary to assess functional status before and after lung surgery to avoid the development of respiratory insufficiency. Objective: To show the changes in the level of arterial blood gases after various ranges of lung resection. Material and methods: The study was done on 71 patients surgically treated at the Clinic for Thoracic Surgery KCU Sarajevo, who were previously treated at the Clinic for Pulmonary Diseases “Podhrastovi” in the period from 01. 06. 2009. to 01. 09. 2011. Different types of lung resection were made. Patients whose percentage of ppoFEV1 was (prognosed postoperative FEV1) was less than 30% of normal values of FEV1 for that patients were not given a permission for lung resection. We monitored the changes in levels-partial pressures of blood gases (PaO2, PaCO2 and SaO2) one and two months after resection and compared them to preoperative values. As there were no significant differences between the values obtained one and two months after surgery, in the results we showed arterial blood gas analysis obtained two months after surgical resection. Results were statistically analyzed by SPSS and Microsoft Office Excel. Statistical significance was determined at an interval of 95%. Results: In 59 patients (83%) there was an increase, and in 12 patients (17%) there was a decrease of PaO2, compared to preoperative values. In 58 patients (82%) there was a decrease, and in 13 patients (18%) there was an increase in PaCO2, compared to preoperative values. For all subjects (group as whole): The value of the PaO2 was significantly increased after lung surgery compared to preoperative values (p <0.05) so is the value of the SaO2%. The value

    Lung contusion affects 17%-25% of adult blunt trauma patients, and is the leading cause of death from blunt thoracic injury. A small animal model for isolated bilateral lung contusion has not been developed. We induced lung contusion in anesthetized rats by dropping a 0.3-kg weight onto a precordial protective shield to direct the impact force away from the heart and toward the lungs. Lung injury was characterized as a function of chest impact energy (1.8-2.7 J) by measurements of arterial oxygenation, bronchoalveolar lavage (BAL) albumin and cytology, pressure-volume mechanics, and histopathology. Histology confirmed bilateral lung contusion without substantial cardiac muscle trauma. Rats receiving 2.7 J of chest impact energy had 33% mortality that exceeded prospectively defined limits for sublethal injury. Hypoxemia in rats with maximal sublethal injury (2.45 J) met criteria for acute lung injury at lung volumes at 48 h. We concluded that an impact energy of 2.45 J induces isolated, bilateral lung contusion and provides a useful model for future mechanistic pathophysiological assessments.

    OBJECTIVE To review the experience of iatrogenic chylothorax after pulmcnary resections for lung cancer and to evaluate our treatment strategy. METHODS From July 1997 through December 2003, a total of 1,546 patients underwent pulmonary resection (at least lobectomy) and systematic mediastinal lymph node dissection for lung cancer in our division. Sixteen patients had a postoperative chylothorax complication. All of these patients in this study were conservatively treated (closed drainage) with complete oral intake cessation and total parenteral nutrition.RESULTS All patients had their condition cured with conservative treatment. The duration of the treatment was 6-21 days. The patients were given normal diet for a mean of 9.8 days after chylothorax diagnosis.CONCLUSION If the correct treatment strategy is selected, most cases of chylothorax after pulmonary resection with systematic mediastinal lymph node dissection can be cured with a conservative strategy.

    OBJECTIVES: A multicentre evaluation of the frequency and nature of major intraoperative complications during video-assisted thoracoscopic (VATS) anatomical resections. METHODS: Six European centres submitted their series of consecutive anatomical lung resections with the intention to treat by VATS....... Conversions to thoracotomy, vascular injuries and major intraoperative complications were studied in relation to surgeons' experience. Major complications included immediate life-threatening complications (i.e. blood loss of more than 2 l), injury to proximal airway or other organs or those leading...... complication. Surgeon's experience was related to non-oncological conversions, but not to vascular injuries or major complications in a multivariable logistic regression analysis. CONCLUSION: Major intraoperative complications during VATS anatomical lung resections are infrequent, seem not to be related...

    Full Text Available Abstract Primary lung myoepithelial carcinomas are rare neoplasms arising from the salivary glands of the respiratory epithelium. Given the rare occurrences and reports of these tumors, appropriate recommendations for resection are difficult to formulate. Although classified as low-grade neoplasms, these tumors have a significant rate of recurrence and distant metastasis.

    Pulmonary nodule could be identified by intraoperative fluorescence imaging system from systemic injection of indocyanine green (ICG) which achieves enhanced permeability and retention (EPR) effects. This study was performed to evaluate optimal injection time of ICG for detecting cancer during surgery in rabbit lung cancer model. VX2 carcinoma cell was injected in rabbit lung under fluoroscopic computed tomography-guidance. Solitary lung cancer was confirmed on positron emitting tomography with CT (PET/CT) 2 weeks after inoculation. ICG was administered intravenously and fluorescent intensity of lung tumor was measured using the custom-built intraoperative color and fluorescence merged imaging system (ICFIS) for 15 hours. Solitary lung cancer was resected through thoracoscopic version of ICFIS. ICG was observed in all animals. Because Lung has fast blood pulmonary circulation, Fluorescent signal showed maximum intensity earlier than previous studies in other organs. Fluorescent intensity showed maximum intensity within 6-9 hours in rabbit lung cancer. Overall, Fluorescent intensity decreased with increasing time, however, all tumors were detectable using fluorescent images until 12 hours. In conclusion, while there had been studies in other organs showed that optimal injection time was at least 24 hours before operation, this study showed shorter optimal injection time at lung cancer. Since fluorescent signal showed the maximum intensity within 6-9 hours, cancer resection could be performed during this time. This data informed us that optimal injection time of ICG should be evaluated in each different solid organ tumor for fluorescent image guided surgery.

    Full Text Available Abstract Background Myocardial infarction can be difficult to diagnose after lung surgery. As recent diagnostic criteria emphasize serum cardiac markers (in particular serum troponin we set out to evaluate its clinical utility and to establish the long term prognostic impact of detected abnormal postoperative troponin levels after lung resection. Methods We studied a historic cohort of patients with primary lung cancer who underwent intended surgical resection. Patients were grouped according to known postoperative troponin status and survival calculated by Kaplan Meier method and compared using log rank. Parametric survival analysis was used to ascertain independent predictors of mortality. Results From 2001 to 2004, a total of 207 patients underwent lung resection for primary lung cancer of which 14 (7% were identified with elevated serum troponin levels within 30 days of surgery, with 9 (64% having classical features of myocardial infarction. The median time to follow up (interquartile range was 22 (1 to 52 months, and the one and five year survival probabilities (95% CI for patients without and with postoperative troponin elevation were 92% (85 to 96 versus 60% (31 to 80 and 61% (51 to 71 versus 18% (3 to 43 respectively (p T stage and postoperative troponin elevation remained independent predictors of mortality in the final multivariable model. The acceleration factor for death of elevated serum troponin after adjusting for tumour stage was 9.19 (95% CI 3.75 to 22.54. Conclusion Patients with detected serum troponin elevation are at high risk of early mortality with or without symptoms of myocardial infarction after lung resection.

    This study compares lung dose distributions for two common techniques of total body photon irradiation (TBI) at extended source-to-surface distance calculated with, and without, tissue density correction (TDC). Lung dose correction factors as a function of lateral thorax separation are approximated for bilateral opposed TBI (supine), similar to those published for anteroposterior-posteroanterior (AP-PA) techniques in AAPM Report 17 (i.e., Task Group 29). 3D treatment plans were created retrospectively for 24 patients treated with bilateral TBI, and for whom CT data had been acquired from the head to the lower leg. These plans included bilateral opposed and AP-PA techniques- each with and without - TDC, using source-to-axis distance of 377 cm and largest possible field size. On average, bilateral TBI requires 40% more monitor units than AP-PA TBI due to increased separation (26% more for 23 MV). Calculation of midline thorax dose without TDC leads to dose underestimation of 17% on average (standard deviation, 4%) for bilateral 6 MV TBI, and 11% on average (standard deviation, 3%) for 23 MV. Lung dose correction factors (CF) are calculated as the ratio of midlung dose (with TDC) to midline thorax dose (without TDC). Bilateral CF generally increases with patient separation, though with high variability due to individual uniqueness of anatomy. Bilateral CF are 5% (standard deviation, 4%) higher than the same corrections calculated for AP-PA TBI in the 6 MV case, and 4% higher (standard deviation, 2%) for 23 MV. The maximum lung dose is much higher with bilateral TBI (up to 40% higher than prescribed, depending on patient anatomy) due to the absence of arm tissue blocking the anterior chest. Dose calculations for bilateral TBI without TDC are incorrect by up to 24% in the thorax for 6 MV and up to 16% for 23 MV. Bilateral lung CF may be calculated as 1.05 times the values published in Table 6 of AAPM Report 17, though a larger patient pool is necessary to better

    During the past 15 years, treatment of stage IIIA (N2) non-small cell lung cancer has evolved considerably because of improvements in patients selection, staging, and combined modality therapy. Results of several clinical trials suggest that induction chemotherapy or chemoradiation and surgical resection is superior to surgery alone. However, the optimal induction regimen has not been defined. An intergroup trial is also underway to determine whether chemoradiation and surgical resection leads to better survival than chemotherapy and radiation alone. Future studies will assess ways to combine radiation and novel chemotherapeutic agents, and will identify molecular abnormalities that predict response to induction therapy.

    Five patients with true convergence excess esotropia were surgically managed with combined resection and recession of the medial rectus muscles. This technique was chosen to address the near/distance angle disparity. The use of this surgical technique produced full asymptomatic binocular control at near and distance fixation in four patients. One patient developed a consecutive exotropia but regained full binocular control following a second surgical procedure.

    Full Text Available Lip reconstruction following resection for tumour or following extensive trauma may pose a challenge. This is more so when the resection is total and a complete lip has to be constructed. We present a case of lip reconstruction following a total resection of the upper lip. The procedure used in this case was a combination of bilateral nasolabial flaps with a submental flap and buccal mucosal graft lining. We believe that this provides an alternative method of total upper lip reconstruction with minimal disruption of the facial aesthesis.

    The aim of the present study was to determine the distribution of lung blood in a modified bilateral Glenn procedure designed in our institute with lung perfusion scintigraphy. Sixteen consecutive patients who underwent modified bilateral Glenn operation from 2011 to 2014 were enrolled in the study. The control group consisted of 7 patients who underwent bidirectional Glenn shunt. Radionuclide lung perfusion scintigraphy was performed using Tc-99m-macro aggregated albumin (MAA) in all patients. For the patients in modified bilateral Glenn group, the time at which the radioactivity accumulation peaked did not differ significantly between the right and left lung field (t = 0.608, P = 0.554). The incidence of perfusion abnormality in each lung lobe also did not differ significantly (P = 0.426 by Fisher exact test). The radioactive counts were higher in the right lung than in the left lung, but the difference was not statistically significant (t = 1.502, P = 0.157). Radioactive perfusion in the lower lung field was significantly greater than that in the upper field (t = 4.368, P lung to that in left lung was significantly lower in the modified bilateral Glenn group (t = 3.686, P = 0.002). Lung perfusion scintigraphy confirmed the benefit of the modified bilateral Glenn shunt with regard to more balanced blood perfusion in both lungs.

    Study Design Case report. Objective To present a rare case of hydrocephalus following bilateral dumbbell-shaped C2 spinal neurofibromas resection and postoperative cervical pseudomeningocele in a patient with neurofibromatosis type 1 (NF1). Methods The patient's clinical course is retrospectively reviewed. A 37-year-old man affected by NF1 referred to our department for progressive weakness of both lower extremities and gait disturbance. Radiological imaging showed bilateral dumbbell-shaped C2 spinal neurofibromas. After its resection, at the 1-month follow-up evaluation, the patient reported headache and nausea. A CT brain scan showed a postoperative cervical pseudomeningocele and an increase in the ventricular sizes, resulting in hydrocephalus. Results A ventriculoperitoneal shunting was performed using a programmable valve opening pressure set to 120 mmH20. After surgery, the patient's neurological status markedly improved. Conclusion Hydrocephalus must be considered a possible complication of cervical spine tumor resection.

    Complete surgical resection is the most effective curative treatment for lung cancer. However, many patients with lung cancer also have severe COPD which increases their risk of postoperative complications and their likelihood of being considered "inoperable." Preoperative pulmonary rehabilitation (PR) has been proposed as an intervention to decrease surgical morbidity but there is no established protocol and no randomized study has been published to date. We tested two preoperative PR interventions in patients undergoing lung cancer resection and with moderate-severe COPD in a randomized single blinded design. Outcomes were length of hospital stay and postoperative complications. The first study tested 4 weeks of guideline-based PR vs. usual care: that study proved to be very difficult to recruit as patients and providers were reluctant to delay surgery. Nine patients were randomized and no differences were found between arms. The second study tested ten preoperative PR sessions using a customized protocol with nonstandard components (exercise prescription based on self efficacy, inspiratory muscle training, and the practice of slow breathing) (n=10) vs. usual care (n=9). The PR arm had shorter length of hospital stay by 3 days (p=0.058), fewer prolonged chest tubes (11% vs. 63%, p=0.03) and fewer days needing a chest tube (8.8 vs. 4.3 days p=0.04) compared to the controlled arm. A ten-session preoperative PR intervention may improve post operative lung reexpansion evidenced by shorter chest tube times and decrease the length of hospital stay, a crude estimator of post operative morbidity and costs. Our results suggest the potential for short term preoperative pulmonary rehabilitation interventions in patients with moderate-severe COPD undergoing curative lung resection. 4 weeks of conventional preoperative PR seems non feasible.

    Background If the emphysema lesions are not symmetrical, unilateral lung volume reduction surgery (LVRS) can be carried out on the more severe side. The aim of this research was to evaluate the feasibility and effects of LVRS performed simultaneously with resection of pulmonary and esophageal neoplasms.Methods Forty-five patients with pulmonary neoplasm and 37 patients with esophageal neoplasm were randomly assigned to group A or group B. In group A, LVRS was performed simultaneously on the same side as thoracotomy. In group B, only tumor resection was performed. The nonfunctional lung area was determined by preoperative chest computed tomography and lung ventilation/perfusion scan. The lung volume removed was about 20% to 30% of the lobes on one side. Preoperative and postoperative indexes including pulmonary function testing variables, arterial blood gas analysis variables, dyspnea scale, 6-minute walk distance, etc., were compared between the groups.Results There were no surgical deaths in this study. The postoperative forced vital capacity in 1 second, PaO_2, PaCO_2,dyspnea scale, and 6-minute walk distance were improved significantly in group A, whereas these indexes did not change or decreased slightly in group B.Conclusions For tumor patients who have associated emphysema, simultaneous LVRS not only increases the chance of receiving surgical therapy, but also improves the postoperative quality of life of the patient. LVRS has expanded thesurgical indication for tumor patients.

    Horseshoe lung, a rare congenital anomaly, is almost always associated with unilateral (usually right-sided) lung hypoplasia, and, in most cases, in conjunction with the scimitar syndrome. We present an 8-month-old boy with horseshoe lung associated with left-lung hypoplasia, left pulmonary artery sling and bilateral agenesis of the upper lobe bronchi, diagnosed by multidetector CT (MDCT) imaging. The study also revealed an anomalous origin of the left vertebral artery as the last branch of the aortic arch, distal to the left subclavian artery, and an anomalous origin of the left common carotid artery from the brachiocephalic trunk. A hemivertebral anomaly of the seventh cervical vertebra was incidentally detected. MDCT with high-quality multiplanar and three-dimensional reconstructions is a noninvasive and rapid technique for detecting the complex combination of vascular, tracheobronchial and parenchymal anomalies, and any potential bone anomalies, in one imaging study.

    The relationship between fetal espiratory activity and fetal lung development has been studied at the cellular level using two experimental models. Chronic bilateral phrenectomy over a period of 20-28 days during the last trimester of the fetal lamb resulted in hypoplastic lungs, although cellular maturity, as indicated by the presence of alveolar epithelial Type II cells, was present. In the lungs from fetal lambs undergoing sham operations for a similar time course there was evidence of enhanced alveolar proliferation when compared with lungs from normal fetal sheep of a similar gastational age, most probably as a result of operative stress. Following chronic bilateral vagotomy no changes in size or histology of the fetal lamb lungs were detected. At an ultrastructural level, however, inclusions of Type II cells consistently showed the loss of the typical osmiophilic lamellated appearance. These results indicate the importance of the fetal breathing apparatus in maintaining a volume of lung liquid which is adequate for normal pulmonary development, particularly during the phase in which alveoli are formed.

    The immune responses of multidrug-resistant tuberculosis (MDR-TB) patients undergoing lung resection surgery were investigated in order to understand the mechanism of strong immune suppression in MDR-TB. We examined changes in cell-mediated immune response (CMI) of a total of sixteen MDR-TB patients, three of them extensively drug-resistant tuberculosis (XDR-TB) patients, after the removal of the heavily diseased lung section. The IFN-γ response to Mycobacterium tuberculosis culture filtrate proteins (Mtb-CFP), one of the most important CMI to defend TB, showed a statistically significant elevation in 2-4 months after operation when compared to the preoperative CMI in patients who were converted into AFB negative and cured in two years' follow-up, suggesting that the recovery of CMI may be one of the key factors in the successful treatment of MDR-TB. Interestingly, IL-10 response to Mtb-CFP was also elevated in 2-4 months after surgery in cured patients although both proliferative response and PBMC composition were not significantly changed. Infection with first- or second-line drugs resistant Mtb reduces the efficiency of chemotherapeutic treatment of MDR-TB to about 50%. Thus, this study suggests that chemotherapeutic treatment of MDR-TB may be more effective when combined with accompanying therapy that increases CMI, includes lung resection surgery.

The predominant growth pattern was classified according to the new classification system for lung adenocarcinoma proposed by the International Association for the Study of Lung Cancer, the American Thoracic Society, and the European Respiratory Society. The correlations of VPI with clinical and pathologic parameters were analyzed.Results: The incidence of VPI was significantly lower in lepidic predominant group (15.5% vs 4.5%, P<0.001 and higher in solid and micropapillary predominant group (28.6% vs 17.6%, P=0.004 and 14.7% vs 4.2%, P<0.001, respectively. VPI correlated with higher risk in regional postoperative recurrence (hazard ratio, 2.341; 95% confidence interval, 1.564–3.504 and distant recurrence (hazard ratio, 2.193; 95% confidence interval, 1.665–2.89 in surgically resected lung adenocarcinomas. However, when growth patterns of adenocarcinoma were lumped into multivariate analysis, VPI was not a significant independent predictive factor for survival (P=0.854 for overall survival [OS] and P=0.575 for disease-free survival [DFS] and recurrence (P=0.38 for regional recurrence and P=0.089 for distant recurrence.

    Despite surgical resectability, early-stage lung cancer remains a challenge to cure. Survival outcomes are hindered by variable performance of adequate lymphadenectomy and the limitations of current pathologic nodal staging. Sentinel lymph node (SLN) mapping, a mainstay in the management of breast cancer and melanoma, permits targeted nodal sampling for efficient and accurate staging that can influence both intraoperative and adjuvant treatment decisions. Unfortunately, standard SLN identification techniques with blue dye and radiocolloid tracers have not been shown to be reproducible in lung cancer. In more recent years, intraoperative near-infrared image-guided lung SLN mapping has emerged as promising technology for the identification of the tumor-associated lymph nodes most likely to contain metastatic disease. Additionally, the clinical relevance of SLN mapping for lung cancer remains pressing, as the ability to identify micrometastatic disease in SLNs could facilitate trials to assess chemotherapeutic response and the clinical effect of occult nodal disease. This review outlines the status of lung cancer lymphatic mapping and techniques in development that may help close the gap between translational research in this field and routine clinical practice.

    Background Although body mass index (BMI) has been used in risk stratification for lung resection, many models only take obesity into account. Recent studies have demonstrated that underweight patients also experience increased postoperative complications. We explored the relationship of extremes of BMI to outcomes after lung resection for non-small cell cancer. Methods Patients in the Society of Thoracic Surgeons General Thoracic Surgery Database (2009 to 2014) undergoing elective lung resection for cancer were evaluated. Multivariable logistic regression was used to adjust for potential confounders including functional status and spirometry. Results We evaluated 41,446 patients (median 68 years of age; 53% female) grouped by BMI: underweight (<18.5 kg/m2; 3.0%), normal (18.5 to 24.9 kg/m2; 33.5%), overweight (25 to 29.9 kg/m2; 35.4%), obese I (30 to 34.9 kg/m2; 18.1%), obese II (35 to 39.9 kg/m2; 6.4%), and obese III (≥40 kg/m2; 3.6%). Pulmonary complication rates were higher in underweight and obese III patients compared to normal BMI patients (p < 0.001). On multivariable analysis, compared to patients with normal BMI, being underweight was associated with an increased risk of pulmonary complications (adjusted odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.16 to 1.70) and any postoperative event (adjusted OR: 1.44, 95% CI: 1.26 to 1.64). Obese III patients had an increased risk of any major postoperative complication (adjusted OR: 1.18, 95% CI: 1.02 to 1.36). Overweight and obese class I to II patients had a lower risk of pulmonary complications and any postoperative event. Conclusions BMI is associated with postoperative complications after lung resection for cancer. Being underweight or severely overweight is associated with an increased risk of complications, whereas being overweight or moderately obese appears to have a protective effect. PMID:27476820

  11. Role of quantitative CT in predicting postoperative FEV1 and chronic dyspnea in patients undergoing lung resection

    Full Text Available Abstract Lung resection is the mainstay of treatment in patients with early stage non-small cell lung cancer. However, lung cancer patients often suffer from comorbidities and the respiratory reserve should be carefully evaluated preoperatively in order to avoid postoperative complications. Forced expiratory volume in 1 second (FEV1 is considered to be an index that depicts the patient's respiratory efficacy and its prediction has a key role in the preoperative evaluation of lung cancer patients with impaired lung function. Prediction of postoperative FEV1 is currently possible with the use of perfusion radionuclide lung scanning. Quantitative CT is the analysis of data acquired during normal chest CT scan using the system's software. By applying a dual threshold of -500 to -910 Hounsfield Units, functional lung volumes are estimated and postoperative FEV1 can be predicted by reducing the preoperative measurement by the fraction of the part to be resected. Studies have shown that preoperative predictions correlate well with the actual postoperative measurements. Additionally, quantitative CT results are in good agreement with perfusion scintigraphy predictions. Newer radiological techniques such as perfusion MRI and co-registered SPECT/CT have also been used in the preoperative evaluation with similar results. In conclusion, chest CT which is obligatory for staging, can be used for quantitative analysis of the already available data. It is technically simple, providing an accurate prediction of postoperative FEV1. Thus, quantitative CT appears to be a useful tool in the preoperative evaluation of lung cancer patients undergoing lung resection.

    The primary objective of this study is to systematically review all pertinent literature related to robotic-assisted lung resection. Robotic-assisted thoracic surgery (RATS) case series and studies comparing RATS with video-assisted thoracoscopic surgery (VATS) or thoracotomy were included in the search. In accordance with preferred reporting items for systematic reviews and meta-analyses guidelines, 2 independent reviewers performed the search and review of resulting titles and abstracts. Following full-text screening, a total of 20 articles met the inclusion criteria and are presented in the review. Amenable results were pooled and presented as a single outcome, and meta-analyses were performed for outcomes having more than 3 comparative analyses. Data are presented in the following 4 categories: technical outcomes, perioperative outcomes, oncological outcomes, and cost comparison. RATS was associated with longer operative time, but did not result in a greater rate of conversion to thoracotomy than VATS. RATS was superior to thoracotomy and equivalent to VATS for the incidence of prolonged air leak and hospital length-of-stay. Oncological outcomes like nodal upstaging and survival were no different between VATS and RATS. RATS was more costly than VATS, with most of the costs attributed to capital and disposable expenses of the robotic platform. Although limited by a lack of prospective analysis, lung resection via RATS compares favorably with thoracotomy and appears to be no different than VATS. Prospective studies are required to determine if there are outcome differences between RATS and VATS.

    Some features found on chest computed tomography (CT), such as central tumor location, large pleural effusion, and the absence of a pleural tail, and a patient age of less than 60 years, have been suggested to be useful in predicting anaplastic lymphoma kinase (ALK) rearrangement in patients with non-small cell lung cancer (NSCLC).A 68-year-old female patient with a history of gynecological treatment was found to have a cavitary mass in the right lower lobe on an annual chest roentgenogram. The tumor was located in the peripheral area with a pleural tail showing no pleural effusion. In addition, two pure ground-glass-opacity nodules (p-GGNs) in the right upper lobe of the lung were detected on consecutive chest CT scans. The patient underwent right lower lobectomy, partial resection of the right upper lobe, and hilar mediastinal lymph node dissection for complete resection of each tumor. The pathological diagnosis was invasive mucinous adenocarcinoma with signet-ring cells for the cavitary mass in the right lower lobe and invasive adenocarcinoma for the rest of the p-GGNs; subcarinal lymph node metastasis was also detected. The ALK rearrangement was detected by fluorescence in situ hybridization from the cavitary mass. The patient underwent four cycles of cisplatin and vinorelbine chemotherapy as standard adjuvant chemotherapy for pStage III NSCLC. The ALK fusion gene status of NSCLC with atypical CT features should also be investigated.

    To assess the diagnostic performance of PET/MR in patients with non-small-cell lung cancer. Fifty consecutive consenting patients who underwent routine {sup 18}F-FDG PET/CT for potentially radically treatable lung cancer following a staging CT scan were recruited for PET/MR imaging on the same day. Two experienced readers, unaware of the results with the other modalities, interpreted the PET/MR images independently. Discordances were resolved in consensus. PET/MR TNM staging was compared to surgical staging from thoracotomy as the reference standard in 33 patients. In the remaining 17 nonsurgical patients, TNM was determined based on histology from biopsy, imaging results (CT and PET/CT) and follow-up. ROC curve analysis was used to assess accuracy, sensitivity and specificity of the PET/MR in assessing the surgical resectability of primary tumour. The kappa statistic was used to assess interobserver agreement in the PET/MR TNM staging. Two different readers, without knowledge of the PET/MR findings, subsequently separately reviewed the PET/CT images for TNM staging. The generalized kappa statistic was used to determine intermodality agreement between PET/CT and PET/MR for TNM staging. ROC curve analysis showed that PET/MR had a specificity of 92.3 % and a sensitivity of 97.3 % in the determination of resectability with an AUC of 0.95. Interobserver agreement in PET/MR reading ranged from substantial to perfect between the two readers (Cohen's kappa 0.646 - 1) for T stage, N stage and M stage. Intermodality agreement between PET/CT and PET/MR ranged from substantial to almost perfect for T stage, N stage and M stage (Cohen's kappa 0.627 - 0.823). In lung cancer patients PET/MR appears to be a robust technique for preoperative staging. (orig.)

    Full Text Available Aim. We describe our experience of a simple, safe, and reproducible technique for lung nodule marking prethoracoscopic metastasectomy. Thoracoscopic lung nodule resection reduces patient discomfort, complications, higher level of care, hospital stay, and cost; however, small deeply placed lung nodules are difficult to locate and resect thoracoscopically. Materials and Methods. We describe and review the success of our novel technique, where nodules are identified on a low dose CT and marked with methylene blue using CT fluoroscopy guidance immediately prior to surgery. Results. 30 nodules were marked with a mean size of 8 mm (4–18 mm located at a mean depth of 17 mm, distributed through both lungs. Dye was detected at the pleural surface in 97% of the patients and at the nodule in 93%. There were no major complications. Thoracoscopic resection was possible in 90%. Conclusion. This is a simple and safe method of lung nodule marking to facilitate thoracoscopic resection in cases where this may not be technically possible due to nodule location.

    Full Text Available Abstract Background The adrenal gland is one of the common sites of metastasis from primary lung cancer. Adrenal metastases are usually unilateral however bilateral adrenal metastases are seen in 10% of all lung cancer patients; of these 2–3% occurs at the initial presentation of non-small cell lung cancer. Secondary tumors can disrupt the structure and function of the adrenal. This can lead to adrenal hemorrhage, which constitutes a life threatening hazard for the patient. Case presentation A 59-year-old male presented with persisting abdominal pain. His initial work-up revealed significant anemia, an invasive process in the right upper lobe of the lung and large masses of heterogeneous texture, with hemorrhagic and necrotic elements in both adrenal glands. A biopsy confirmed it to be a large-cell carcinoma of the lungs. The patient developed severe leukocytosis akin to the paraneoplastic syndrome and died suddenly five days after the administration of chemotherapy. Conclusion Intratumoral hemorrhage is a rare but life threatening complication of adrenal metastases and should be treated as soon as it has been diagnosed. If adrenalectomy is not feasible, combination chemotherapy should be applied as in metastatic disease. For choosing the appropriate chemotherapeutic regimen it is important to accurately achieve the diagnosis.

    Full Text Available Lymphangioleiomyomatosis (LAM is a rare disease that leads to airways and lymphatic channels obstruction due to abnormal smooth muscle proliferation. It presents with dyspnea, pneumothorax or chylothorax. Lung transplantation (LT has emerged as a valuable therapeutic option with limited reports. We report a case of LAM that underwent double LT and complicated by refractory bilateral chylothorax which was managed successfully by povidone-iodine pleurodesis and the addition of sirolimus to the post-transplantation immunosuppressive therapy. The patient has no recurrence with 24 months follow-up.

    Full Text Available Abstract Background CD44s is a cell adhesion molecule known to mediate cellular adhesion to the extracellular matrix, a prerequisite for tumor cell migration. CD44s plays an important role in invasion and metastasis of various cancers. In the present study, we sought to determine whether CD44s is involved in clinical outcomes of patients with resected non-small cell lung cancer (NSCLC. Methods Using immunohistochemical staining, we investigated CD44s protein expression using tissue array specimens from 159 patients with resected NSCLC (adenocarcinoma (AC; n = 82 and squamous cell carcinoma (SCC; n = 77. Additionally, the immunoreactivity of cyclooxygenase (COX-2 was also studied. The clinicopathological implications of these molecules were analyzed statistically. Results High CD44s expression was detected more frequently in NSCLC patients with SCC (66/72; 91.7% than in those with AC histology (P 0.001. Additionally, high CD44s expression was significant correlated with more advanced regional lymph node metastasis (P = 0.021. In multivariate analysis of survival in NSCLC patients with AC histology, significant predictors were lymph node metastasis status (P P = 0.046, and high CD44s expression (P = 0.014. For NSCLC patients with SCC histology, the significant predictor was a more advanced tumor stage (P = 0.015. No significant association was found between CD44s and clinical outcome (P = 0.311. Conclusions High CD44s expression was a negative prognostic marker with significance in patients with resected NSCLC, particularly those with AC histology, and was independent of tumor stage.

    To review the results of postoperative radiation therapy (PORT) for residual non-small cell lung cancer (NSCLC) following surgical resection and evaluate multiple clinicopathologic prognostic factors. A total of 58 patients, who completed scheduled PORT for positive resection margin, among 658 patients treated with PORT from January 2001 to November 2011 were retrospectively analyzed. Radiation therapy was started at 4 to 6 weeks after surgery. Chemotherapy was also administered to 35 patients, either sequentially or concurrently with PORT. The median age of patients was 63 years (range, 40 to 82 years). The postoperative pathological stage I NSCLC was diagnosed in 10 (17.2%), stage II in 18 (31.0%), and stage III in 30 patients (51.7%). Squamous cell carcinoma was identified in 43, adenocarcinoma in 10, large cell in 1, others in 4 patients. Microscopic residual disease (R1) was diagnosed in 55 patients (94.8%), and the remaining three patients were diagnosed with gross residual disease (R2). The median dose of PORT was 59.4 Gy (range, 50.0 to 64.8 Gy). Chemotherapy was administered to 35 patients (60%), and the median follow-up time was 22.0 months (range, 6.0 to 84.0 months). The 3-year locoregional relapse-free survival and distant metastasis-free survival rates were 82.1% and 52.9%, respectively. The median overall survival was 23.8 months (range, 6.0 to 84.1 months), and the 3-year overall survival rate was 58.2%. Chemotherapy did not influence the failure pattern or survival outcome. PORT is an effective modality for improving local tumor control in incompletely resected NSCLC patients. Major failure pattern was distant metastasis despite chemotherapy.

    BACKGROUND: Prognostic and predictive biomarkers are increasingly used to customise the treatment of patients with solid tumours. Intra- and inter-tumour heterogeneous distribution of biomarker expression is a potential confounder for the use of biomarkers, as small biopsies may not necessarily...... truly reflect the pattern of biomarker expression. It may also be an important factor in chemo resistance, as tumours with heterogeneous biomarker expression may potentially harbour chemo resistant tumour clones.

    Full Text Available Abstract Adjuvant chemotherapy for non-small-cell lung carcinoma (NSCLC is a debated issue in clinical oncology. Although it is considered a standard for resected stage II-IIIA patients according to the available guidelines, many questions are still open. Among them, it should be acknowledged that the treatment for stage IB disease has shown so far a limited (if sizable efficacy, the role of modern radiotherapies requires to be evaluated in large prospective randomized trials and the relative impact of age and comorbidities should be weighted to assess the reliability of the trials' evidences in the context of the everyday-practice. In addition, a conclusive evidence of the best partner for cisplatin is currently awaited as well as a deeper investigation of the fading effect of chemotherapy over time. The limited survival benefit since first studies were published and the lack of reliable prognostic and predictive factors beyond pathological stage, strongly call for the identification of bio-molecular markers and classifiers to identify which patients should be treated and which drugs should be used. Given the disappointing results of targeted therapy in this setting have obscured the initial promising perspectives, a biomarker-selection approach may represent the basis of future trials exploring adjuvant treatment for resected NSCLC.

    Methylation is closely involved in the development of various carcinomas. However, few datasets are available for small cell lung cancer (SCLC) due to the scarcity of fresh tumor samples. The aim of the present study is to clarify relationships between clinicopathological features and results of the comprehensive genome-wide methylation profile of SCLC. We investigated the genome-wide DNA methylation status of 28 tumor and 13 normal lung tissues, and gene expression profiling of 25 SCLC tissues. Following unsupervised hierarchical clustering and non-negative matrix factorization, gene ontology analysis was performed. Clustering of SCLC led to the important identification of a CpG island methylator phenotype (CIMP) of the tumor, with a significantly poorer prognosis (P = 0.002). Multivariate analyses revealed that postoperative chemotherapy and non-CIMP were significantly good prognostic factors. Ontology analyses suggested that the extrinsic apoptosis pathway was suppressed, including TNFRSF1A, TNFRSF10A and TRADD in CIMP tumors. Here we revealed that CIMP was an important prognostic factor for resected SCLC. Delineation of this phenotype may also be useful for the development of novel apoptosis-related chemotherapeutic agents for treatment of the aggressive tumor.

    Background Radical lung resection is the best chance for cure in patients with anatomically resectable non-small cell lung cancer.A retrospective study was performed in an attempt to investigate general rules of major lung resection for non-small cell lung cancer in patients with compromised pulmonary function.Methods Between June 2002 and December 2008,major lung resection was performed in 127 non-small cell lung cancer patients at our institution,who met the criteria of compromised pulmonary function defined as preoperative forced vital capacity <50% of prediction or preoperative forced expiratory volume in one second <50% of prediction.Clinical data of the patients were retrospectively reviewed.Results The patients consisted of 108 males (85.0%) and 19 females (15.0%) with a mean age of 61.7 years.The morbidity rate was 44.1% (56/127) and the mortality rate was 4.7% (6/127).Multivariate analysis identified PaCO2 (P=0.023,OR=2.959,95% C/ 1.164-7.522),the percent predicted postoperative diffusing capacity of the lung for carbon monoxide (P=0.001,OR=0.176,95% C/ 0.064-0.480) and comprehensive preoperative preparation (P=0.048,OR=0.417,95% C/ 0.176-0.993) as the independent predictors of postoperative cardiopuimonary complications that were found in 45 cases.Overall 1-,3- and 5-year survival rates were 90%,55% and 37% respectively.For overall survival,multivariate analysis revealed that TNM staging (P=0.004,OR=1.585,95% C/ 1.154-2.178) was the only independent prognostic factor.Conclusions On the premise of integrated preoperative evaluation and comprehensive preoperative preparation,major lung resection provides an optimal therapeutic for selected non-small cell lung cancer patients with compromised pulmonary function.Hypercapnea and the percent predicted postoperative diffusing capacity of the lung for carbon monoxide <40% could be considered as the independent predictive factors for operative risk in those patients.Chin Med J

    When suitable, surgery still remains the therapeu-tic option to be preferred for patients carrier of colorectal liver and lung metastases. Since thoracophrenolaparotomy should be helpful during liver resection for some of these patients, si-multaneous removal of right lung metastases can be proposed through this approach. Eleven consecutive patients (median age of 53 years) carrier of colorectal liver and lung metastases, underwent single session surgical resection of both liver and right lung lesions by means of J-shaped thoracophrenolapa-rotomy. The median number of liver metastases removed was 5 (range 2-30) and of lung metastases removed was 2 (range 1-3). Lung metastases were located in the upper lobe in 1 pa-tient, in the middle lobe in 2, in the lower lobe in 6, and in the upper and lower lobe in 2. Mortality and major morbidity were nil. Two patients had a minor morbidity: one had wound infection and bile leakage treated conservatively and the other had transient fever. Mean overall survival was 24.4 months. An aggressive surgical approach should be undertaken for colorectal metastases: in case of multifocal liver disease with complex presentations, J-shaped thoracophrenolaparotomy could be considered as safe approach for combined liver and right lung metastasectomies.

    Pneumonia in elderly people is mainly caused by silent aspiration due to an age-related impairment of cough and swallowing reflexes. Because most of the patients with lung cancer are elderly people, we hypothesized that the age-related impairment of these protective reflexes might exist or occur in patients undergoing lung surgery, and cause postoperative pneumonia. We revealed that many elderly patients showed depressed swallowing reflex even before surgery and transient attenuation of cough reflex after surgery, and that postoperative pneumonia occurred only in the patients whose cough and/or swallowing reflex was abnormal postoperatively. Then, we prospectively showed that 30 elderly patients who received perioperative intensive oral care, including professional assessment of oral status, dental cleaning, and patient education for self-oral care by dentists, followed by intensive oral care by intensive care unit nurses, and encouragement of self-oral care by floor nurses, did not develop pneumonia after lung resection. In this study, we retrospectively reviewed the execution status of professional oral care by dentists and the occurrence of postoperative pneumonia in 159 consecutive patients aged 65 or older undergoing lung resection from 2013 to 2014. Thoracic surgeons in our institute asked dentists to provide professional oral care before lung resection only in 30.3% of the subjects in 2013, and 45.8% in 2014. Postoperative pneumonia occurred in 3 out of 76 subjects(3.9%)in 2013, and 1 out of 83(1.2%) in 2014. In 2013, 1 patient who did not receive preoperative professional oral care developed aspiration pneumonia postoperatively followed by acute exacerbation of idiopathic pulmonary fibrosis and in-hospital death. We need to make an effective system to provide preoperative professional oral care by dentists especially for elderly patients and high-risk patients before lung resection.

    Full Text Available For many years, surgery alone was the standard treatment for patients with stage I-IIIA non-small-cell lung cancer (NSCLC. However, recent studies have demonstrated that adjuvant chemotherapy provides a survival benefit. The first adjuvant chemotherapy for NSCLC was performed in the 1960s using a key drug known as cyclophosphamide. In the 1980s and early 1990s, a new anti-cancer drug, cisplatin, was developed. The first meta-analysis of this drug was conducted by the Non-small Cell Lung Cancer Collaborative Group in 1995. This analysis comparing surgery with surgery plus chemotherapy containing cisplatin produced a hazard ratio of 0.87 and suggested an absolute benefit of chemotherapy of 5% at 5 years;this difference was not statistically significant (p0.08. Several clinical trials of adjuvant chemotherapy were planned after the meta-analysis conducted in 1995, but the efficacy of adjuvant chemotherapy remained a matter of controversy. However, useful evidence was reported after 2003. The International Adjuvant Lung Cancer Collaborative Group Trial (IALT demonstrated a 4.1% improvement in survival for patients with stage I to III NSCLC. The JBR. 10 trial demonstrated a 15% improvement in 5-year survival for the adjuvant chemotherapy arm in stage IB or II (excluding T3N0 patients. The Adjuvant Navelbine International Trialist Association (ANITA trial reported that the overall survival at 5 years improved by 8.6% in the chemotherapy arm and that this survival rate was maintained at 7 years (8.4% in stage II and IIIA patients. A meta-analysis based on collected and pooled individual patient data from the 5 largest randomized trials was conducted by the Lung Adjuvant Cisplatin Evaluation (LACE. This analysis demonstrated that cisplatin-based adjuvant chemotherapy improved survival in patients with stage II or III cancer. Alterna-tively, uracil-tegafur has been developed and tested in Japan.

    Full Text Available OBJECTIVE: To evaluate whether external suction is more advantageous than water seal in patients undergoing selective pulmonary resection (SPR for lung neoplasm. SUMMARY OF BACKGROUND DATA: Whether external suction should be routinely applied in postoperative chest drainage is still unclear, particularly for lung neoplasm patients. To most surgeons, the decision is based on their clinical experience. METHODS: Randomized control trials were selected. The participants were patients undergoing SPR with lung neoplasm. Lung volume reduction surgery and pneumothorax were excluded. Suction versus non-suction for the intervention. The primary outcome was the incidence of persistent air leak (PAL. The definition of PAL was air leak for more than 3-7 days. The secondary outcomes included air leak duration, time of drainage, postoperative hospital stay and the incidence of postoperative pneumothorax. Studies were identified from literature collections through screening. Bias was analyzed and meta-analysis was used. RESULTS: From the 1824 potentially relevant trials, 6 randomized control trials involving 676 patients were included. There was no difference between external suction and water seal in decreasing the incidence of PAL [95% confidence interval (CI 0.81-2.16; z = 1.10; P = 0.27]. Regarding secondary outcomes, there were no differences in time of drainage (95% CI-0.36-1.56, P = 0.22, postoperative hospital stay (95% CI -.31-.54, P = 0.87 or incidence of postoperative pneumothorax (95% CI 0.18-.02, P = 0.05 between external suction and water seal. CONCLUSIONS: For participants, no differences are identified in terms of PAL incidence, drainage time, length of postoperative hospital stay or incidence of postoperative pneumothorax between external suction and water seal. The bias analysis should be emphasized. To the limitations of the bias and methodological differences among the included studies, we have no recommendation on

    Full Text Available Purpose: The purpose of this study is to evaluate the dosimetric effect of rotational setup errors on the synchronous bi-lateral lung cancer plans generated by the intensity modulated proton therapy (IMPT technique.Methods: The original IMPT plans were generated in for the left planning target volume (PTV and right PTV of the left lung and right lung, respectively. Each plan was generated using two beams (lateral and posterior-anterior with an isocenter placed at the center of the corresponding PTV. The IMPT plans were optimized for a total dose of 74 Gy[RBE] prescribed to each PTV with 2 Gy(RBE per fraction. Original plans were recalculated by introducing simulated rotational errors. For each PTV, 18 rotational plans (±1⁰, ±2⁰, and ±3⁰ for each of the yaw, roll, and pitch rotations were generated. Results: Rotational errors caused the reduction in the clinical target volume (CTV and PTV coverage in new rotational IMPT plans when compared to the original IMPT lung plans. The CTV D99 was reduced by up to 13.3%, 9.1%, and 5.9% for the yaw (+3⁰, roll (-3⁰, and pitch (+3⁰, respectively. The PTV D95 was reduced by up to 8.7%, 7.3%, and 4.6% for the yaw (+3⁰, roll (-3⁰, and pitch (+3⁰, respectively. The PTV V100 showed the highest deviation with a reduction of dose coverage by up to 40.1%, 31.8%, and 33.9% for the yaw (-3⁰, roll (-3⁰, and pitch (+3⁰ respectively. Conclusion: The rotational setup errors with magnitude of ≥2⁰ can produce a significant loss of dose coverage to the target volume in the IMPT of a synchronous bi-lateral lung cancer. The yaw had the most severe impact on the dosimetric results when compared to other two rotational errors (roll and pitch.

    Full Text Available Background. Angiogenic factors following oncological surgery is important in tumor recurrence. Vascular endothelial growth factor (VEGF, angiopoietin 1 (Ang-1, Ang-2, soluble VEGF-receptor 1 (sVEGFR1 and sVEGFR2 may influence angiogenesis. This prospective study examined the influence of open and video-assisted thoracic surgery (VATS lung resections for early stage non-small cell lung cancer (NSCLC on postoperative circulating angiogenic factors. Methods. Forty-three consecutive patients underwent major lung resection through either VATS (=23 or Open thoracotomy (=20 over an 8-month period. Blood samples were collected preoperatively and postoperatively on days (POD 1 and 3 for enzyme linked immunosorbent assay determination of angiogenic factors. Results. Patient demographics were comparable. For all patients undergoing major lung resection, postoperative Ang-1 and sVEGFR2 levels were significantly decreased, while Ang-2 and sVEGFR1 levels markedly increased. No significant peri-operative changes in VEGF levels were observed. Compared with open group, VATS had significantly lower plasma levels of VEGF (VATS 170±93 pg/mL; Open 486±641 pg/mL; =0.04 and Ang-2 (VATS 2484±1119 pg/mL; Open 3379±1287 pg/mL; =0.026 on POD3. Conclusions. Major lung resection for early stage NSCLC leads to a pro-angiogenic status, with increased Ang-2 and decreased Ang-1 productions. VATS is associated with an attenuated angiogenic response with lower circulating VEGF and Ang-2 levels compared with open. Such differences in angiogenic factors may be important in lung cancer biology and recurrence following surgery.

    This is a retrospective study of 23 patients in whom bilateral diffuse lung uptake (BDLU) of radioactivity was seen on Ga-67 scans. Of the 23 patients, 10 patients were histologically or clinically diagnosed as having respiratory diffuse or active diseases, consisting of lung cancer (5), pulmonary tuberculosis (3), silicosis (one), lung fibrosis (one), 4 as having malignant lymphoma, 3 as having multiple myeloma, and single patients as having chronic myelocytic leukemia, hepatoma, bladder cancer, skin cancer, cholecystitis, and fever of unknown origin. In all of the patients, except for one, the estimated causes of BDLU were clarified as follows: silicosis in 9 patients, pleuritis in 4, chemotherapy in 6, and radiation pneumonitis, and tuberculosis in each one. The extent of BDLU on Ga-67 scans was larger than lesions seen on chest X-ray films. This implies the involvement of blood flow changes in Ga-67 uptake. BDLU on Ga-67 scans, except for cases of pleuritis associated with malignant lymphoma, did not imply poor prognosis. Silicosis accounted for 40% of all patients, which may reflect the endemic prevalence in the present population living in a pottery district. (N.K.).

    Full Text Available IntroductionAdenocarcinomas, commonly present as a dominant lesion (DL with additional nodules in the ipsilateral or contralateral lung. We sought to determine the fate and management of the secondary nodules and to assess the risk of these nodules using the Lung CT Screening Reporting and Data System (Lung-RADS criteria and the National Comprehensive Cancer Network (NCCN guidelines to determine if surveillance is an appropriate strategy.MethodsWe retrospectively evaluated patients with lepidic growth pattern adenocarcinoma and secondary nodules from 2000 to 2013. Risk assessment of the additional lesions was completed with a simplified model of Lung-RADS and NCCN-Guidelines. ResultsEighty-seven patients underwent resection of 87 DLs (Group 1 concurrently with 60 additional pulmonary nodules (Group 2 while 157 non-DLs were radiologically surveyed over a median follow-up time of 3.2 years (Group 3. Malignancy was found in 29/60 (48% nodules in Group 2. Whereas, only 9/157 (6% of the lesions in Group 3 enlarged, 4 of which (2.5% of total were found to be malignant, and then treated, while the remaining nodules continued surveillance. After applying the Lung-RADS and NCCN simplified models, nodules in Group 2 were at higher risk for lung cancer than those in Group 3. ConclusionsIn patients with lepidic growth pattern adenocarcinoma associated with multiple secondary nodules, surveillance of the remaining nodules, after resection of the DL, is a reasonable strategy since these nodules exhibited a slow rate of growth and minimal malignancy. In contrast, nodules resected from the ipsilateral lung at the time of the DL, harbor malignancy in 48%. Risk assessment models may provide a useful and standardized tool for clinical assessment of pulmonary nodules.

    Full Text Available Background. Tuberculosis (TB is a major cause of morbidity and mortality globally. Many cases are diagnosed on autopsy and a subset of patients may require surgical intervention either due to the complication or sequelae of TB. Materials and Methods. 40 cases of resected lung specimens following surgery or autopsy in which a diagnosis of pulmonary tuberculosis was made were included. Histopathological pattern analysis of pulmonary tuberculosis along with associated nonneoplastic changes and identification of Mycobacterium tuberculosis bacilli was done. Results. The mean age of diagnosis was 41 years with male predominance (92.5%. Tuberculosis was suspected in only 12.1% of cases before death. Seven cases were operated upon due to associated complications or suspicion of malignancy. Tubercular consolidation was the most frequent pattern followed by miliary tuberculosis. The presence of necrotizing granulomas was seen in 33 cases (82.5%. Acid fast bacilli were seen in 57.5% cases on Ziehl-Neelsen stain. Conclusion. Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.

    Vascular clamping during lung cancer resection may be difficult in patients with short vessels or large neoplasms preventing adequate and safe exposure. In addition, the physiological vicinity of some vessels to rigid structures like the bronchi may interfere with ideal clamp positioning even in ordinary procedures. We have modified the original Blalock clamp to facilitate the control of pulmonary vessels and physiologically compress the vessel walls, thereby allowing optimal vascular resecti...

    Full Text Available Background and objective Video-assisted mini-thoracoscopy (VAMT has been used for pulmonary lobectomy for 20 years, which has many merits including small wound, less pain and quick recovery. VAMT is the tendency of pectoral minimally invasive surgical treatment. The aim of this study is to evaluate the efficacy of video-assisted mini-thoracoscopy (VAMT for radical resection of pleomorphic carcinoma of the lung. Methods Complete resection of pleomorphic carcinoma of the lung was performed on 28 patients by VMAT. A 1.5 cm and a 6 cm to 8 cm incision was made during the operation. Both standard surgical instruments and thoracoscopic set were used to treat the pulmonary vessels, perform lobotomy, and remove the lymph nodes in the mediastinum and pulmonary portal. Results The operation was completed in all of the cases. No peri-operative death occurred. The total volume of hemorrhage was 200 mL to 450 mL (mean, 300 mL. The patients received chest drainage for 3 to 8 days after the operation (mean, 5 d. The time in hospital was 7 d-14 d (mean, 12 d. Five-year overall survival and disease-free survival were 39.2% and 47.1%, respectively. Follow-up was available in all 28 patients for up to 2 to 91 months. Among the 28 cases, only 2 patients died 2 months after the operation, the rest all live up over 1 year. 3-year survival rate was 60.7% (95%CI: 40.3%-81.1%. Conclusion VAMT is effective for radical resection of pleomorphic carcinoma of the lung in a short term. Combination the superiority of traditional procedure and VATS, so VAMT is safe and reliable for radical resection of pleomorphic carcinoma of the lung.

    Lung contusion is the leading cause of death from blunt thoracic trauma in adults, but its mechanistic pathophysiology remains unclear. This study uses a recently developed rat model to investigate the evolution of inflammation and injury in isolated lung contusion. Bilateral lung contusion with minimal cardiac trauma was induced in 54 anesthetized rats by dropping a 0.3-kg hollow cylindrical weight onto a precordial shield (impact energy, 2.45 Joules). Arterial oxygenation, pressure-volume (P-V) mechanics, histology, and levels of erythrocytes, leukocytes, albumin, and inflammatory mediators in bronchoalveolar lavage (BAL) were assessed at 8 min, at 4, 12, 24, and 48 h, and at 7 days after injury. The role of neutrophils in the evolution of inflammatory injury was also specifically studied by depleting these cells with intravenous vinblastine before lung contusion. Arterial oxygenation was severely reduced at 8 min to 24 h postcontusion, but became almost normal by 48 h. Levels of erythrocytes, leukocytes, and albumin in BAL were increased at lung injury based on total lung volume at 4 h and on BAL albumin levels at 24 h postcontusion. Inflammatory injury from isolated bilateral lung contusion in rats is most severe in the acute period (8 min-24 h) after initial blunt trauma, and includes a component of neutrophil-dependent pathology.

In the present study, we examined the correlation of serum and lung inflammatory marker levels following bilateral femur fracture.Materials and methods: 45 Sprague Dawley rats underwent sham operation or bilateral femoral intramedullary pinning and mid-diaphyseal closed fracture via blunt guillotine. Animals were euthanized at specific time points after injury. Serum and lung tissue were collected, and 24 inflammatory markers were analyzed by immunoassay. Lung histology was evaluated by a blinded pathologist.Results: Bilateral femur fracture significantly increased serum markers of inflammation including interleukin (IL-2, IL-6, IL-10, GM-CSF, KC/GRO, MCP-1, and WBC. Femur fracture ­significantly increased serum and lung levels of IL-1a and KC/GRO at 6 hours. Lung levels of IL-6 ­demonstrated a trend towards significance. Histologic changes in pulmonary tissue after fracture included pulmonary edema and bone elements including cellular hematopoietic cells, bone fragments and marrow emboli.Discussion and conclusion: Our results indicate that bilateral femur fracture with fixation in rats results in increases in serum markers of inflammation. Among the inflammatory markers measured, rise in the serum KC/GRO (CINC-1, a homolog to human IL-8, correlated with elevated levels of lung KC/GRO. Ultimately, analysis of serum levels of KC/GRO (CINC-1, or human IL-8, may be a useful adjunct to guide clinical decisions regarding surgical timing.Keywords: blunt trauma, injury, cytokine, IL-8, bone marrow emboli

    Purpose The goals of our study were (a) to validate a molecular expression signature (cell cycle progression [CCP] score and molecular prognostic score [mPS; combination of CCP and pathological stage {IA or IB}]) that identifies stage I lung adenocarcinoma (ADC) patients with a higher risk of cancer-specific death following curative-intent surgical resection, and (b) to determine whether mPS stratifies prognosis within stage I lung ADC histological subtypes. Methods Formalin-fixed, paraffin-embedded stage I lung ADC tumor samples from 1200 patients were analyzed for 31 proliferation genes by quantitative RT-PCR. Prognostic discrimination of CCP score and mPS was assessed by Cox proportional hazards regression, using 5-year lung cancer–specific mortality as the primary outcome. Results In multivariable analysis, CCP score was a prognostic marker for 5-year lung cancer–specific mortality (HR=1.6 per interquartile range; 95% CI, 1.14–2.24; P=0.006). In a multivariable model that included mPS instead of CCP, mPS was a significant prognostic marker for 5-year lung cancer–specific mortality (HR=1.77; 95% CI, 1.18–2.66; P=0.006). Five-year lung cancer–specific survival differed between low-risk and high-risk mPS groups (96% vs 81%; P<0.001). In patients with intermediate-grade lung ADC of acinar and papillary subtypes, high mPS was associated with worse 5-year lung cancer–specific survival (P<0.001 and 0.015, respectively), compared with low mPS. Conclusion This study validates CCP score and mPS as independent prognostic markers for lung cancer–specific mortality and provides quantitative risk assessment, independent of known high-risk features, for stage I lung ADC patients treated with surgery alone.

    Intraoperative alveolar air leaks occur in patients with non-small-cell lung cancer (NSCLC) following a pulmonary resection using thoracoscopic surgery. We showed the efficacy of covering damaged lung tissue with a subcutaneous fat pad for preventing postoperative air leak. Thoracoscopic surgery was performed for NSCLC patients with three incisions along with a 3-4 cm anterior utility incision. When an air leak originated from deep within the pulmonary parenchyma or was large, a subcutaneous fat pad ∼2 × 2 cm in size was harvested from the utility incision and placed on the damaged lung tissue with fibrin glue and 2-3 mattress sutures. Subcutaneous fat pads were used for 50 patients with NSCLC during thoracoscopic surgery procedures. There were no intraoperative complications in any of the patients. A prolonged air leak (>7 days) was noted in 3 (6%) of the 50 patients. Air leak was diminished at 1.5 ± 2.6 postoperative days and the chest tubes removed at 3.2 ± 2.8 postoperative days. Reinforcement of damaged lung tissues by use of subcutaneous free fat pads is a safe and intriguing procedure in NSCLC patients who underwent a pulmonary resection in thoracoscopic surgery.

    OBJECTIVE To assess the accuracy of multi-slice spiral CT (MSCT) with imaging reconstruction in judging central pulmonary vascular involvement from central lung cancer, and to explore its ability to predict the resectability of lung cancer.METHODS MSCTs were conducted on 48 patients who were diagnosed preoperatively with central lung cancer. Images of pulmonary arteries and veins that might affect Iobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the relationship of the tumor to the vessels was assessed prospectively on both axial CT images and axial CT images plus reconstructed images(CT-RI) in comparison to subsequent pathologic and surgical findings.RESULTS MSCTs were obtained on all 48 patients whom 42 underwent thoracotomy, Iobectomy or pneumonectomy. Compared with the axial CT images,CT-RI was more accurate in judging the relationship of the central pulmonary vessels to the tumor based on subsequent pathologic 78 vessels studiedand surgical findings (186 vessels studied) (0.01 <P<0.05). The sensitivity and positive predictive value of unresectability of the vessels were all remarkably higher with CT-RI (P<0.01).CONCLUSION MSCT with imaging reconstruction can improve the recognition of neoplastic invasion of central pulmonary vessels. It can be used to predict preoperatively the resectability of central lung cancer and to plan surgery.

    ,760 patients with T1aN0M0 NSCLC after surgery from the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and lung cancer-specific survival (LCSS) were compared among patients after lobectomy, segmentectomy, or wedge resection. The proportional hazards model was applied to evaluate...... multiple prognostic factors. RESULTS: OS and LCSS favored lobectomy compared with segmentectomy or wedge resection in patients with NSCLC ≤ 1 cm and > 1 to 2 cm. Multivariable analysis showed that segmentectomy and wedge resection were independently associated with poorer OS and LCSS than lobectomy...... for NSCLC ≤ 1 cm and > 1 to 2 cm. With sublobar resection, lower OS and LCSS emerged for NSCLC > 1 to 2 cm after wedge resection, whereas similar survivals were observed for NSCLC ≤ 1 cm. Multivariable analyses showed that wedge resection is an independent risk factor of survival for NSCLC > 1 to 2 cm...

    2014-10-01

    Full Text Available Congenital Pulmonary Airway Malformations (CPAMs are abnormalities of lung parenchyma that are often diagnosed upon prenatal imaging as opposed to postnatal symptoms. With a clinical presentation identical to CPAMs, Pleuropulmonary Blastoma (PPB is a rare pulmonary neoplasm of highly malignant potential. We present a rare case of a female infant with a vague medical history of respiratory distress syndrome (RDS at birth, presenting with a tension pneumothorax at three months of age, thought initially to be secondary to CPAM, but found to be PPB upon surgical resection and histological analysis. PPB is a rare pulmonary neoplasm of childhood that originates from the primitive interstitium of the lung, resulting in lesions that can be highly malignant. It is classified as type I (cystic, type II (cystic/solid or type III (solid, with a progression of disease and worsening prognosis from type I to type III. Due to the cystic nature of CPAM and PPB it is difficult to differentiate on imaging alone; diagnosis must be made based on histological analysis. The highly malignant nature and potential for morbidity and mortality of PPB should make clinicians consider early resection of cystic lung lesions preferentially on an elective basis.

    Full Text Available Introduction: Neodymium:yttrium aluminum garnet (Nd:YAG laser resection is one of the most established interventional pulmonology techniques for immediate debulking of malignant central airway obstruction (CAO. The major aim of this study was to investigate the complication rate and identify clinical risk factors for complications in patients with advanced lung cancer. Methods: In the period from January 2006 to January 2011, data sufficient for analysis were identified in 464 patients. Nd:YAG laser resection due to malignant CAO was performed in all patients. The procedure was carried out in general anesthesia. Complications after laser resection were defined as severe hypoxemia, global respiratory failure, arrhythmia requiring treatment, hemoptysis, pneumothorax, pneumomediastinum, pulmonary edema, tracheoesophageal fistulae, and death. Risk factors were defined as acute myocardial infarction within 6 months before treatment, hypertension, chronic arrhythmia, chronic obstructive pulmonary disease (COPD, stabilized cardiomyopathy, previous external beam radiotherapy, previous chemotherapy, and previous interventional pulmonology treatment. Results : There was 76.1% male and 23.9% female patients in the study, 76.5% were current smokers, 17.2% former smokers, and 6.3% of nonsmokers. The majority of patients had squamous cell lung cancer (70%, small cell lung cancer was identified in 18.3%, adenocarcinoma in 3.4%, and metastases from lung primary in 8.2%. The overall complication rate was 8.4%. Statistically significant risk factors were age (P = 0.001, current smoking status (P = 0.012, arterial hypertension (P < 0.0001, chronic arrhythmia (P = 0.034, COPD (P < 0.0001, and stabilized cardiomyopathy (P < 0.0001. Independent clinical risk factors were age over 60 years (P = 0.026, arterial hypertension (P < 0.0001, and COPD (P < 0.0001. Conclusion : Closer monitoring of patients with identified risk factors is advisable prior and immediately after

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'in patients with primary lung carcinoma, does the sequence of pulmonary vasculature ligation during anatomical lung resection influence the oncological outcomes?' A total of 48 papers were found using the reported search, of which 7 represented the best evidence to answer the question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Among six prospective studies included, five of them randomized patients to either pulmonary vein or artery occlusion first during anatomical lung resection, while one study was retrospective. Two reports did not find any difference between pulmonary vein and artery occlusion first during long-term follow-up in terms of either disease recurrence (51 vs 53%, P = 0.7), or 5-year overall survival (54 vs 50%, P = 0.82). One report did not find any difference with regard to circulating tumour cells either after thoracotomy (5.0 vs 3.9, P = 0.4), or after the completion of lobectomy (38.0 vs 70.0, P = 0.23). One report found a higher expression of CD44v6 (P = 0.008) and CK19 (P = 0.05) in patients undergoing pulmonary arterial occlusion first. One report found that pulmonary vein occlusion before that of the pulmonary arterial branches has a favourable outcome on circulating carcino-embryonic antigen (CEA) mRNA in the peripheral blood, while another one did not find a significant difference in circulating levels of CEA mRNA (P = 0.075) and CK19 mRNA (P = 0.086) with either method. Another study reported no correlation between circulating pin1 mRNA levels in peripheral blood after the completion of the resection and the sequence of ligation of pulmonary vessels (9.95 ± 0.91 vs 14.71 ± 1.64, P > 0.05). Based on the two studies assessing the long-term outcome of patients with primary lung cancer undergoing anatomical curative

    The occurrence of a tumor at the colostomy site after abdominoperineal resection for rectal carcinoma is rare and it may be related to a previously resected carcinoma or another primary tumor. We report a 61-year-old man who developed an ulcerated skin nodule at her colostomy site 6 years after resection of a rectal adenocarcinoma. Histopathologically, the skin nodule was composed of atypical large and pleomorphic cells with high mitotic rate and they were arranged in nests and within lymphatic channels in the dermis. The neoplastic cells were immunoreactive for cytokeratin (CK) AE1/3, CK7, CK34ßE12, epithelial membrane antigen and vimentin while detection of human papillomavirus and Epstein-Barr virus DNA was negative. A diagnosis of basaloid large cell carcinoma of pulmonary origin was suggested and it was confirmed by computed tomography-guided fine needle aspiration of a right subpleural mass. A metastatic tumor at the colostomy site is an exceptional finding and may be the first manifestation of lung cancer, especially if it consist of pleomorphic large cells with high mitotic rate and basaloid immunophenotype.

    Excision repair cross-complementing gene 1 (ERCC1) protein is proposed as a predictor for cisplatin efficacy in patients with non-small cell lung cancer (NSCLC). However, recent studies declare that ERCC1 is not associated with the response of platinum-based chemotherapy or clinical outcomes. The purpose of this study is to assess whether ERCC1 expression level is linked to cisplatin sensitivity and clinical outcomes in resected NSCLC patients. Paraffin-embedded cancer samples from 112 patients were used for immunohistochemical staining. Cancer cells isolated from fresh tumor tissues were used to determine the sensitivity to cisplatin by MTT assay. The association between ERCC1 expression and cisplatin sensitivity was tested by Spearman's rho test. The correlation of ERCC1 expression with clinicopathologic parameters was evaluated by the chi-square tests. The relationship between variables and survival was assessed by log-rank test. Overall survival (OS) and disease-free survival (DFS) curves were plotted by the Kaplan-Meier method. Cox proportional hazards model was used for multivariate analysis of survival. ERCC1 expression was significantly correlated with the sensitivity of cisplatin in vitro (p < 0.01, r = 0.37). ERCC1 was not associated with OS (p = 0.17) or DFS (p = 0.13) in patients with resected NSCLC. ERCC1 is not a sensible marker for the choice of treatment in clinical patients with resected NSCLC.

    This study was conducted to observe the outcomes of postoperative radiotherapy (PORT) with or without concurrent chemotherapy in resected non-small cell lung cancer (NSCLC) in single institution. From 2002 to 2013, 78 patients diagnosed with NSCLC after curative resection were treated with radiotherapy alone (RT, n = 48) or concurrent chemoradiation (CCRT, n = 30). The indications of adjuvant radiation therapy were N2 node positive (n = 31), close or involved resection margin (n = 28), or gross residual disease due to incomplete resection (n = 19). The median radiation dose was 57.6 Gy (range, 29.9 to 66 Gy). Median survival time was 33.7 months (range, 4.4 to 140.3 months). The 5-year overall survival (OS) rate was 49.5% (RT 46% vs. CCRT 55.2%; p = 0.731). The 3-year disease-free survival rate was 45.5% (RT 39.4% vs. CCRT 55.3%; p = 0.130). The 3-year local control rate was 68.1% (RT 64.4% vs. CCRT 77.7%; p = 0.165). The 3-year DMFS rate was 56.1% (RT 52.6% vs. CCRT 61.7%; p = 0.314). In multivariate analysis, age > or =66 years and pathologic stage III were significant poor prognostic factors for OS. Treatment failure occurred in 40 patients. Four patients had radiologically confirmed grade 3 radiation pneumonitis. In NSCLC, adjuvant RT or CCRT after curative surgery is a safe and feasible modality of treatment. OS gain was seen in patients less than 66 years. Postoperative CCRT showed a propensity of achieving better local control and improved disease-free survival compared to RT alone according to our data.

    Purpose: To analyze patterns of local-regional failure (LRF) for completely resected stage IIIA(N2) non-small cell lung cancer (NSCLC) patients treated in our hospital and to propose a clinical target volume (CTV) for postoperative radiation therapy (PORT) in these patients. Methods and Materials: From 2005 to 2011, consecutive patients with pT1-3N2 NSCLC who underwent complete resection in our hospital but who did not receive PORT were identified. The patterns of first LRF were assessed and evaluated as to whether these areas would be encompassed by our proposed PORT CTV. Results: With a median follow-up of 24 months, 173 of 250 patients (69.2%) experienced disease recurrence. Of the 54 patients with LRF as the first event, 48 (89%) had recurrence within the proposed PORT CTV, and 6 (11%) had failures occurring both within and outside the proposed CTV (all of which occurred in patients with right-lung cancer). Ninety-three percent of failure sites (104 of 112) would have been contained within the proposed PORT CTV. For left-sided lung cancer, the most common lymph node station failure site was 4R, followed by 7, 4L, 6, 10L, and 5. For right-sided lung cancer, the most common site was station 2R, followed by 10R, 4R, and 7. Conclusions: LRF following complete surgery was an important and potentially preventable pattern of failure in stage IIIA(N2) patients. Ipsilateral superior mediastinal recurrences dominated for right-sided tumors, whereas left-sided tumors frequently involved the bilateral superior mediastinum. Most of the LRF sites would have been covered by the proposed PORT CTV. A prospective investigation of patterns of failure after PORT (following our proposed CTV delineation guideline) is presently underway and will be reported in a separate analysis.

    Objective: To evaluate the effect of postoperative adjuvant chemotherapy on survival after complete resection of stage Ⅲ-N2 non-small-cell lung cancer. Methods: From Jan. 1999 to Dec. 2003, one-hundred and fifty patients, who were diagnosed as stage Ⅲ-N2 non-small cell lung cancer after operation, were randomly devided into chemotherapy group and control group. The former received four cycles of chemotherapy with NVB (25 mg/m2,D1, D5)/paclitaxel (175 mg/m2, DI) and Carboplatin (AUC=5, D1). Results: In chemotherapy group, 75.8% (68/79) of patients had finished the 4 cycles of chemotherapy and no one died of toxic effects of chemotherapy.Twenty-five percent of the patients had grade 3-4 neutropenia and 2% had febrile neutropenia. The median survival for the entire 150 patients was 879 d, with 1-year survival rate of 81%, 2-year survival rate of 59% and 3-year survival rate of 43%. There was no significant difference in median survival between chemotherapy and control group (897 d vs 821 d, P=0.0527), but there was significant difference in the 1-year and 2-year overall survival (94.71%, 76.28% vs 512 d, P=0.122), but there was significant difference in the 2-year survival rate between two groups with brain metastases (66.7% vs 37.6% P<0.05). The median survival after brain metastasis appeared was 190 days. Conclusion: Postoperative adjuvant chemotherapy does not significantly improve median survival among patients with completely resected stage Ⅱ-N2 non-small-cell lung cancer, but significantly improves the 1-year and 2-year overall survival. It neither decreases the incidence of brain metastasis but put off the time of brain metastasis.

    Full Text Available The present study was carried out in order to determine the effect of lung resection on the frequency of infections in alloxan-diabetic rats. Adult female Wistar rats were injected with alloxan (40 mg/kg, iv to induce diabetes mellitus (group D; N = 45 or with vehicle (1.0 ml/kg, iv to be used as controls (group C; N = 45. Thirty-six days after receiving alloxan both groups were randomly divided into three subgroups: no operation (NO; N = 15, sham operation (SO; N = 15, and left pneumonectomy (PE; N = 15. The rats were sacrificed 36 days after surgery and their lungs were examined microscopically and macroscopically. The occurrence of thoracic wall infection, thoracic wall abscess, lung abscess and pleural empyema was similar in groups D and C. In contrast, the overall infection rate was higher (P<0.05 in the diabetic rats (SO-D and PE-D subgroups, but not in the NO-D subgroup. Considering that the overall infection rate was similar in the SO-D and PE-D subgroups, we suggest that surgery but not pneumonectomy was related to the higher prevalence of infection in diabetic rats.

    A 63-year-old man was admitted to the hospital with fever and bilateral, peripheral infiltrates. Infectious disease and malignancy seemed to be excluded by fiberoptic diagnostic procedures. Subsequently, respiratory insufficiency developed, making open lung biopsy impossible. The diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) was strongly considered and treatment with corticosteroids was started; this led to dramatic clinical and radiologic improvement for a short time. Eventually, an open lung biopsy specimen disclosed primary extranodal non-Hodgkin's lymphoma of T-cell origin, immunoblastic, of high-grade malignancy according to the Kiel classification. After the first course of chemotherapy, total respiratory insufficiency developed and the patient died. This case is unique in a patient without AIDS.

    Full Text Available Surgery is the treatment of choice for patients with non-small cell lung cancer (NSCLC stages I-IIIA. However, more than 20% of these patients develop recurrence and die due to their disease. The release of tumor cells into peripheral blood (CTCs is one of the main causes of recurrence of cancer. The objectives of this study are to identify the prognostic value of the presence and characterization of CTCs in peripheral blood in patients undergoing radical resection for NSCLC.56 patients who underwent radical surgery for previously untreated NSCLC were enrolled in this prospective study. Peripheral blood samples for CTC analysis were obtained before and one month after surgery. In addition CTCs were phenotypically characterized by epidermal growth factor receptor (EGFR expression.51.8% of the patients evaluated were positive with the presence of CTCs at baseline. A decrease in the detection rate of CTCs was observed in these patients one month after surgery (32.1% (p = 0.035. The mean number of CTCs was 3.16 per 10 ml (range 0-84 preoperatively and 0.66 (range 0-3 in postoperative determination. EGFR expression was found in 89.7% of the patients at baseline and in 38.9% patients one month after surgery. The presence of CTCs after surgery was significantly associated with early recurrence (p = 0.018 and a shorter disease free survival (DFS (p = .008.

    Marco Alifano

    Full Text Available BACKGROUND: Hypothesizing that nutritional status, systemic inflammation and tumoral immune microenvironment play a role as determinants of lung cancer evolution, the purpose of this study was to assess their respective impact on long-term survival in resected non-small cell lung cancers (NSCLC. METHODS AND FINDINGS: Clinical, pathological and laboratory data of 303 patients surgically treated for NSCLC were retrospectively analyzed. C-reactive protein (CRP and prealbumin levels were recorded, and tumoral infiltration by CD8+ lymphocytes and mature dendritic cells was assessed. We observed that factors related to nutritional status, systemic inflammation and tumoral immune microenvironment were correlated; significant correlations were also found between these factors and other relevant clinical-pathological parameters. With respect to outcome, at univariate analysis we found statistically significant associations between survival and the following variables: Karnofsky index, American Society of Anesthesiologists (ASA class, CRP levels, prealbumin concentrations, extent of resection, pathologic stage, pT and pN parameters, presence of vascular emboli, and tumoral infiltration by either CD8+ lymphocytes or mature dendritic cells and, among adenocarcinoma type, tumor grade (all p285 mg/L prealbumin levels and high (>96/mm2 CD8+ cell count had a 5-year survival rate of 80% [60.9-91.1] as compared to 18% [7.9-35.6] in patients with an opposite pattern of values. When stages I-II were considered alone, the prognostic significance of these factors was even more pronounced. CONCLUSIONS: Our data show that nutrition, systemic inflammation and tumoral immune contexture are prognostic determinants that, taken together, may predict outcome.

    @@ Lung transplantation has been performed internationally as an effective treatment for a variety of end-stage lung diseases. A great disparity between the supply of donor organs and the demand of potential recipients has resulted in longer waiting time and annual increases in deaths on the lung transplant waiting list. Living-donor lobar lung transplantation (LDLLT) has become an established strategy to deal with the shortage of cadaveric donors. Encouraged by Starnes et al1 and Date et al,2 we began to apply the operation to a critically ill patient with bronchopulmonary dysplasia (BPD) firstly at Shanghai Pulmonary Hospital in China.

    Purpose Surgical resection of isolated hepatic or pulmonary metastases of colorectal cancer is an established procedure, with a 5-year survival rate of about 50%. However, the role of surgical resections in patients with both hepatic and pulmonary metastases is not well established. We aimed to analyze overall survival of these patients and associated factors. Methods Data retrospectively collected from 66 patients who underwent both hepatic and pulmonary metastasectomy after colorectal cancer surgery from August 2002 through August 2013 were analyzed. In univariate analysis, the log-rank test compared patient survival between groups. P < 0.1 was considered indicative of significance. Multivariate analysis of the significance data using a Cox proportional hazard model identified factors associated with overall survival. The synchronous group (n = 57) was defined as patients who had metastasectomy within 3 months from primary colorectal cancer surgery. The remaining nine patients constituted the metachronous group. Results Median follow-up was 126 months from the primary colorectal cancer surgery. The 5-year survival was 73.4%. There was no difference in overall survival between the synchronous and metachronous groups, consistent with previous studies. Distribution (involving one hemiliver or both, P = 0.010 in multivariate analysis) of liver metastases and multiplicity of the pulmonary metastasis (P = 0.039) were predictors of poor prognosis. Conclusion Sequential or simultaneous resection of both hepatic and pulmonary metastasis of colorectal cancer resulted in good long-term survival in selected patients. Thus, an aggressive surgical approach and multidisciplinary decision making with surgeons seems to be justified. PMID:28203555

    Purpose: Current National Comprehensive Cancer Network guidelines recommend postoperative radiation therapy (PORT) for patients with resected non-small cell lung cancer (NSCLC) with N2 involvement. We investigated the relationship between nodal stage and local-regional recurrence (LR), distant recurrence (DR) and overall survival (OS) for patients having an R0 resection. Methods and Materials: A multi-institutional database of consecutive patients undergoing R0 resection for stage I-IIIA NSCLC from 1995 to 2008 was used. Patients receiving any radiation therapy before relapse were excluded. A total of 1241, 202, and 125 patients were identified with N0, N1, and N2 involvement, respectively; 161 patients received chemotherapy. Cumulative incidence rates were calculated for LR and DR as first sites of failure, and Kaplan-Meier estimates were made for OS. Competing risk analysis and proportional hazards models were used to examine LR, DR, and OS. Independent variables included age, sex, surgical procedure, extent of lymph node sampling, histology, lymphatic or vascular invasion, tumor size, tumor grade, chemotherapy, nodal stage, and visceral pleural invasion. Results: The median follow-up time was 28.7 months. Patients with N1 or N2 nodal stage had rates of LR similar to those of patients with N0 disease, but were at significantly increased risk for both DR (N1, hazard ratio [HR] = 1.84, 95% confidence interval [CI]: 1.30-2.59; P=.001; N2, HR = 2.32, 95% CI: 1.55-3.48; P<.001) and death (N1, HR = 1.46, 95% CI: 1.18-1.81; P<.001; N2, HR = 2.33, 95% CI: 1.78-3.04; P<.001). LR was associated with squamous histology, visceral pleural involvement, tumor size, age, wedge resection, and segmentectomy. The most frequent site of LR was the mediastinum. Conclusions: Our investigation demonstrated that nodal stage is directly associated with DR and OS but not with LR. Thus, even some patients with, N0-N1 disease are at relatively high risk of local recurrence. Prospective

    Full Text Available In previous studies, we identified 29 tumor-associated antigens (TAAs and isolated 488 human monoclonal antibodies (mAbs that specifically bind to one of the 29 TAAs. In the present study, we performed histochemical analysis of 36 freshly resected lung cancer tissues by using 60 mAbs against 27 TAAs. Comparison of the staining patterns of tumor cells, bronchial epithelial cells, and normal pulmonary alveolus cells and interalveolar septum allowed us to determine the type and location of cells that express target molecules, as well as the degree of expression. The patterns were classified into 7 categories. While multiple Abs were used against certain TAAs, the differences observed among them should be derived from differences in the binding activity and/or the epitope. Thus, such data indicate the versatility of respective clones as anti-cancer drugs. Although the information obtained was limited to the lung and bronchial tube, bronchial epithelial cells represent normal growing cells, and therefore, the data are informative. The results indicate that 9 of the 27 TAAs are suitable targets for therapeutic Abs. These 9 Ags include EGFR, HER2, TfR, and integrin α6β4. Based on our findings, a pharmaceutical company has started to develop anti-cancer drugs by using Abs to TfR and integrin α6β4. HGFR, PTP-LAR, CD147, CDCP1, and integrin αvβ3 are also appropriate targets for therapeutic purposes.

    Neodymium yttrium-aluminium-garnet (Nd : YAG) laser resection is one of the mostly used interventional pulmonology techniques for urgent desobstruction of malignant central airway obstruction (CAO). The major aim of this trial was to evaluate potential influence of Nd : YAG laser resection on overall quality of life (QoL) in patients with central lung cancer. Patients with malignant CAO scheduled for Nd : YAG laser resection were prospectively recruited in the trial. All patients were given European Organization for Research and Treatment, Quality of Life questionnaire (EORTC QLQ-30 v.3) before the procedure and approximately 2 weeks after the treatment. There were 37 male and 10 female patients, average age 54 ± 10 years. Most common tumour type was adenocarcinoma diagnosed in 51% of patients. Majority of patients were diagnosed in stage IIIB (53.2%) and stage IV (25.5%). Most common Eastern Cooperative Oncology Group performance status was 1 (72.3%). Nd : YAG laser resection significantly improved (Plife, social activities and financial situation, we did not observe statistically significant improvement. Nd : YAG laser resection of malignant CAO significantly improves QoL and overall health in patients with lung cancer.

Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD. Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed.Results: A total of 172 patients were diagnosed with COPD (124 as GOLD-1, 46 as GOLD-2, and two as GOLD-3. The frequencies of recurrence were significantly higher in patients with higher COPD grades (P<0.001. Recurrence-free survival at 5 years was 78.1%, 70.4%, and 46.4% in non-COPD, mild COPD, and moderate/severe COPD groups, respectively (P<0.001. By univariate analysis, the age, sex, smoking history, COPD severity, tumor size, histology, and pathological stage were associated with recurrence-free survival. Multivariate analysis showed that older age, male, moderate/severe COPD, and advanced stage were independent risk factors associated with recurrence-free survival.Conclusion: NSCLC patients with COPD are at high risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor.

    Takotsubo cardiomyopathy which is characterised by a transient left ventricular wall motion abnormality was first described in 1990. The disease is still not well known, and as such it is suggested that an emotional trigger is mandatory in this disease. We present the case of a 51-year old female patient seven years after bilateral lung transplantation, who developed acute respiratory distress syndrome and subsequently suffered from atypical takotsubo cardiomyopathy with transient severe reduction of ejection fraction and haemodynamic instability needing acute intensive care treatment. Acute respiratory failure has emerged as an important physical trigger factor in takotsubo cardiomyopathy. Little is known about the association of hypoxia and takotsubo cardiomyopathy which can elicit a life-threatening condition requiring acute intensive care. Therefore, experimental studies are needed to investigate the role of hypoxia in takotsubo cardiomyopathy.

    Bronchiectasis is a major cause of morbidity and mortality in developing countries. Staged bilateral segmental resection of the lungs is performed in selected patients. Our experience of surgical removal of 87 bilateral bronchiectases in 29 patients during an 11-year period was reviewed retrospectively. High-resolution computed tomography was performed preoperatively in all patients to locate the anatomic sites of bronchiectasis. The mortality and morbidity of the surgical procedure, clinical symptoms, age distribution, etiology, bacteriology, and operative procedures were analyzed. There were 22 males (76%) and 7 females (24%), aged 5 to 60 years, with a mean age of 30 years. Complications developed in 11 patients (38%); atelectasia was the most common (14%). There was one hospital death. Clinical symptoms disappeared in 19 (66%) patients, improved in 5 (17%), and were unchanged in 4 (14%). Staged bilateral resection for bronchiectases can be performed at any age with acceptable morbidity and mortality.

    Objective:To investigate the influence of thoracic minimally invasive laparoscopic surgery and conventional thoracotomy on lung function, inflammatory factor and stress response for esophageal cancer patients.Methods:In this study, 288 cases of esophageal cancer patients were collected in our hospital from January 2011 to January 2016. Patients were randomly divided into observation group (n=144) and control group (n=144), the observation group received thoracic minimally invasive laparoscopic surgery and control group underwent conventional open surgery. The levels of inflammatory cytokines indicators [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-8, IL-10] and stress response [white blood cell count (WBC), three free triiodothyronine (FT3), free thyroxine (FT4), C-reactive protein (CRP), cortisol] were detected 1 d, 3 d and 5 d after surgery. Lung function [percent predicted vital capacity (VC%), percentage of predicted forced expiratory volume (FEV%), forced expiratory volume in 1 second percentage of predicted value (FEV1%), FVC% predicted percentage (FVC%), accounted for the maximum ventilation per minute, percentage of predicted value (MVV%)] of patients in two groups were measured 1 month after surgery.Results:Compared with the control group, VC and FVC in the observation group were significantly higher 1 month after surgery; the levels of TNF-α in patients of observation group were significantly lower than the control group 1 d, 3 d and 5 d after surgery; the levels IL-6, IL-8 and IL-10 in patients of observation group were significantly lower than the control group 1 d and 3 d after surgery but not on Day5. No significant difference was found in WBC, FT3, FT4, CRP and cortisol levels between the two groups.Conclusion:Compared with conventional thoracotomy, thoracic minimally invasive laparoscopic surgery can effectively reduce surgical trauma and inhibit the release of inflammatory factors, bring less effect on lung function and improve the

    Full Text Available Introduction. Rapidly vanishing lung pseudotumor (phantom tumor refers to the transient well-demarcated accumulation of pleural fluid in the interlobar pulmonary fissures. Most frequently their appearance is associated with congestive heart failure, but also other disorders like hypoalbuminemia, renal insufficiency or pleuritis. Its rapid disappearance in response to the treatment of the underlying disorder is a classical feature of this clinical entity. Case report. A 47-yearold woman, chronic smoker with symptoms of shortness of breath, orthopnea, chills, cough, weakness and the temperature of 39.2°C was admitted to our hospital. A posteroanterior chest X-ray revealed cardiomegaly with the cardiothoracic ratio of > 0.5, blunting of both costophrenic angles and an adjacent 6 x 5 cm well-defined, rounded opacity in the right interlobar fissure. Transthoracic 2-dimensional echocardiography demonstrated left ventricular hyperthrophy with a systolic ejection fraction of 25% and moderate mitral regurgitation. The patient’s symptoms resolved rapidly after diuresis, and repeated chest X-ray four days later showed that the right lung opacity and pleural effusions had vanished. Conclusion. The presented case underlines the importance of the possibility of vanishing lung tumor in patients with left ventricular failure and a sharp oval lung mass on the chest X-ray. This is the way to avoid incorrect interpretation of this finding causing additional, unnecessary, costly or invasive imaging, interventions and drugs.

    Full Text Available Hepatocellular cancer (HCC is increasing dramatically in incidence in Europe and the United States due mainly to the hepatitis C epidemic and, to a lesser extent, increased body mass index of the population. In the fairly recent past, HCC was largely considered as untreatable due to detection mainly at late stages and lack of effective drugs for treatment. Several advances have led to changes in the prognosis of HCC. Screening of high-risk populations has allowed for earlier detection in some studies. If found at an early stage, liver transplantation not only cures the usual underlying cirrhosis but has cure rates for HCC in the range of 60% in recent series. Larger lesions can sometimes be cured by partial hepatic resection assuming the remaining liver is not too damaged to sustain liver functions after surgery. Vaccination for hepatitis B has led to reduction in the incidence of HCC. Significant improvements in antiviral treatments for both hepatitis B and hepatitis C may be having an impact on the incidence of HCC as well. It is still generally held that a finding of metastases precludes cure of HCC. We here report the case of a patient who presented with a large HCC in the context of occult hepatitis C infection. The primary tumor was resected. Over a year later, he developed a lung metastasis that was resected as well. He has not shown recurrence for 6 years since the metastasectomy. We review the recent literature on resection of lung metastases from HCC.

    Full Text Available Abstract Background This study was designed to establish a biomarker risk model for predicting bone metastasis in stage III non-small cell lung cancer (NSCLC. Methods The model consists of 105 cases of stage III NSCLC, who were treated and followed up. The patients were divided into bone metastasis group (n = 45 and non-bone metastasis group (other visceral metastasis and those without recurrence (n = 60. Tissue microarrays were constructed for immunohistochemical study of 10 molecular markers associated with bone metastasis, based on which a model was established via logistic regression analysis for predicting the risk of bone metastases. The model was prospectively validated in another 40 patients with stage III NSCLC. Results The molecular model for predicting bone metastasis was logit (P = − 2.538 + 2.808 CXCR4 +1.629 BSP +0.846 OPN-2.939 BMP4. ROC test showed that when P ≥ 0.408, the sensitivity was up to 71% and specificity of 70%. Model validation in the 40 cases in clinical trial (NCT 01124253 demonstrated that the prediction sensitivity of the model was 85.7%, specificity 66.7%, Kappa: 0.618, with a high degree of consistency. Conclusion The molecular model combining CXCR4, BSP, OPN and BMP4 could help predict the risk of bone metastasis in stage IIIa and IIIb resected NSCLC.

    Full Text Available Objective To explore the therapeutic effect and degree of safety in patients aged 80 years or over with nonsmall cell lung cancer undergoing radical resection. Methods A retrospective survey of 97 elder patients aged 80 years or over, in whom non-small cell lung cancer was pathologically confirmed after partial resection of the lung in Chinese PLA General Hospital from Jan. 2003 to Dec. 2012. The peri-operative features were evaluated, including gender, age, history of smoking, pulmonary function, surgical procedure, histopathologic type, pathologic stage, etc. The relation of the postoperative complications and mortality with the factors mentioned above was analyzed. Results Among all patients, the surgical procedure comprised 36 lobectomies, 31 segmentectomies, and 30 wedge resections. The histopathologic diagnosis showed there were adenocarcinoma in 51 patients, squamous cell carcinoma in 29, large cell carcinoma in 9, adenosquamous cell carcinoma in 6 and neuro-endocrine cell carcinomas in 2. The disease stage was determined as ⅠA in 55 cases, ⅠB in 33, ⅡA in 7, ⅢA in 2. The post-operative complications (POC occurred in 14 of 97 patients (14.4%, and the most common complication was cardiovascular complication (9 cases, followed by pulmonary complication (5 cases. Only two patients died to the complications, one of them was post-operative pneumonia and respiratory failure, and the other one was acute myocardial infarction. The survival rate of the 97 patients was 91.7%, 70.2% and 52.8% at 1, 3 and 5 years, respectively, and in the patients with stage I disease, the survival rate was 93.9%, 73.6% and 54.1%, respectively. Conclusion Advanced age is not a contraindication to radical pulmonary resection in patients over 80 years old suffering from early stage non-small cell lung cancer.

    moderately increasing the depth of sedation while maintaining spontaneous breathing. Finally, as long as the physiologic impact of awake metastasectomy is definitively elucidated, the authors believe this modality should be used for unilateral procedures, while deserving a staged bilateral approach for bilateral lung metastasectomy. Avoidance of general anesthesia results in a faster recovery with immediate return to many daily life activities, including drinking, eating, and walking, and a reduction in hospital stay and procedure-related costs. If confirmed with future studies, these results could advocate earlier resection of peripheral solitary pulmonary nodules, reducing the risk for delaying a diagnosis of unexpected pulmonary malignancy. Furthermore, potential new frontiers of awake thoracoscopic surgery might include assessment of feasibility and safety of anatomic resections in properly selected instances. Ethical and economical concerns push remorselessly for less frequent and less-invasive surgery. Administrators advocate minimal hospitalization and cost-saving treatments, whereas patients ultimately ask for appropriate health care. Thoracic surgeons of the third millennium must accept the challenge of this dynamic and rapidly evolving scenario without loosing the right root, which probably lays just between well-established conventional surgery techniques and newly available advanced technology tools. Awake thoracic surgery will benefit from evidence-based data that are progressively accumulating. Findings will stimulate experts to continue an active clinical investigation in this unpredictably evolving surgical field, which might ultimately lead to a better understanding of cardiorespiratory physiology and effects of the surgical pneumothorax and thoracic epidural anesthesia on perioperative, respiratory function in awake patients.

    Background The prognosis of R1-resection at the bronchial stump in patients with non-small cell lung cancer (NSCLC) remains unclear.This study intends to identify the prognostic factors and to optimize treatments for these patients under update conditions.Methods The data of 124 NSCLC patients who underwent R1-resection at the bronchial stump was reviewed.There were 41 patients in the surgery group (S),21 in the postoperative radiotherapy (PORT) group (S+R),30 in the postoperative chemotherapy (POCT) group (S+C),and 32 in the PORT plus POCT group (S+R+C).The constitute proportion in different groups was tested using the X2 method,univariate analysis was performed using the Kaplan-Meier and log-rank method,and multivariate analysis was done using the Cox hazard regression with entry factors including age,sex,pathological type and stage,classification of the residual disease,and treatment procedure.The process was performed stepwise backward with a maximum iteration of 20 and an entry possibility of 0.05 as well as an excluded possibility of 0.10 at each step.Results In univariate analysis,survival was more favorable for patients with squamous cell carcinoma,early pathological T or N stage,and chemotherapy or radiotherapy.There was no significant difference in the survival for patients with different types of the residual disease,except for the difference between patients with carcinoma in situ and lymphangiosis carcinomatosa (P=0.030).The survival for patients receiving chemoradiotherapy was superior to that for those undergoing surgery alone (P=0.016).In multivariate analysis,the pathological type (HR 2.51,95% CI 1.59 to 3.96,P=0.000),pathological T (HR 1.29,95% CI 1.04 to 1.60,P=-0.021) or N stage (HR 2.04,95% CI 1.40 to 2.98,P=0.000),and chemotherapy (HR 0.24,95% CI 0.13 to 0.43,P=0.000) were independent prognostic factors.Conclusion Patients with squamous cell carcinoma,early pathological T or N stage,or receiving chemotherapy had a more favorable

    Lung metastases in healthy patients should be removed non-anatomically whenever possible. This can be done with a laser. Lung parenchyma can be cut very well, because of its high energy absorption at a wavelength of 1940 nm. A coagulation layer is created on the resected surface. It is not clear, whether this surface also needs to be sutured to ensure that it remains airtight even at higher ventilation pressures. It would be helpful, if suturing could be avoided, because the lung can become too puckered, especially with multiple resections, resulting in considerable restriction. We carried out our experiments on isolated and ventilated paracardiac lung lobes of pigs. Non-anatomic resection was carried out reproducibly using three different thulium laser fibres (230, 365 and 600 μm) at two different laser power levels (10 W, 30 W) and three different resection depths (0.5, 1.0 and 2.0 cm). Initial airtightness was investigated while ventilating at normal frequency. We also investigated the bursting pressures of the resected areas by increasing the inspiratory pressure. When 230- and 365-μm fibres were used with a power of 10 W, 70 % of samples were initially airtight up to a resection depth of 1 cm. This rate fell at depths of up to 2 cm. All resected surfaces remained airtight during ventilation when 600-μm fibres were used at both laser power levels (10 and 30 W). The bursting pressures achieved with 600-μm fibres were higher than with the other fibres used: 0.5 cm, 41.6 ± 3.2 mbar; 1 cm, 38.2 ± 2.5 mbar; 2 cm, 33.7 ± 4.8 mbar. As laser power and thickness of laser fibre increased, so the coagulation zone became thicker. With a 600-μm fibre, it measured 145.0 ± 8.2 μm with 10 W power and 315.5 ± 6.4 μm with 30 W power. Closure with sutures after non-anatomic resection of lung parenchyma is not necessary when a thulium laser is used provided a 600-μm fibre and adequate laser power (30 W) are employed. At deeper

    A resected case of huge liver metastasis of hepatoid adenocarcinoma of the lung is described. A 77-year-old man who presented a solitary huge liver tumor was admitted to our hospital. He had undergone right lower lobectomy of the lung for lung cancer one year before. The view of imaging studies was not a typical one of hepatocellular carcinoma. Serum levels of AFP and PIVKA-II were 334,500ng/mL and 3,890mAU/mL, respectively, and the proportion of AFP L3 was 97.9%. It was thought that they were strongly diagnostic for hepatocellular carcinoma. Extended right lobectomy of the liver was performed. Microscopically, it was poorly differentiated adenocarcinoma and diagnosed as liver metastasis from the formerly resected lung cancer. The tumor was composed of cells with both sheet-like growth and tubule formation. The neoplastic cells, in the sheet-like growth resembled hepatocellular carcinoma cells. By immunohistochemical staining with anti-AFP and anti-PIVKA-II antibodies, cancer cells of both the primary and metastatic lesions were positive. The patient eventually died of multiple liver and bone metastasis 6 months after the operation.

Methods: In this randomized, controlled trial, 356 patients with stage I (except for T1N0, II and IIIA NSCLC were assigned to either the preoperative chemotherapy plus surgery arm (179 patients or the primary surgery arm (177 patients. Both treatments were followed by adjuvant chemotherapy. The end point of this study included overall survival (OS, progression-free survival (PFS, and survival rate associated with clinical remission. Results: Statistical survival difference was found between the preoperative chemotherapy plus surgery arm and the surgery-alone arm. However, the median survival time (MST in the preoperative chemotherapy arm was lower than that of surgery-alone arm (MST, 45.42 months vs 57.59 months (P = 0.016.

    Purpose Our institution has implemented two different adjuvant protocols in treating patients with non-small cell lung cancer (NSCLC): chemotherapy followed by concurrent chemoradiotherapy (CT-CCRT) and sequential postoperative radiotherapy (PORT) followed by postoperative chemotherapy (POCT). We aimed to compare the clinical outcomes between the two adjuvant protocols. Materials and Methods From March 1997 to October 2012, 68 patients were treated with CT-CCRT (n = 25) and sequential PORT followed by POCT (RT-CT; n = 43). The CT-CCRT protocol consisted of 2 cycles of cisplatin-based POCT followed by PORT concurrently with 2 cycles of POCT. The RT-CT protocol consisted of PORT followed by 4 cycles of cisplatin-based POCT. PORT was administered using conventional fractionation with a dose of 50.4–60 Gy. We compared the outcomes between the two adjuvant protocols and analyzed the clinical factors affecting survivals. Results Median follow-up time was 43.9 months (range, 3.2 to 74.0 months), and the 5-year overall survival (OS), locoregional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were 53.9%, 68.2%, and 51.0%, respectively. There were no significant differences in OS (p = 0.074), LRFS (p = 0.094), and DMFS (p = 0.490) between the two protocols. In multivariable analyses, adjuvant protocol remained as a significant prognostic factor for LRFS, favouring CT-CCRT (hazard ratio [HR] = 3.506, p = 0.046) over RT-CT, not for OS (HR = 0.647, p = 0.229). Conclusion CT-CCRT protocol increased LRFS more than RT-CT protocol in patients with completely resected NSCLC, but not in OS. Further studies are warranted to evaluate the benefit of CCRT strategy compared with sequential strategy. PMID:27730801

    Purpose Selenium has been reported to have chemopreventive benefits in lung cancer. We conducted a double-blind, placebo-controlled trial to evaluate the incidence of second primary tumors (SPTs) in patients with resected non–small-cell lung cancer (NSCLC) receiving selenium supplementation. Patients and Methods Patients with completely resected stage I NSCLC were randomly assigned to take selenized yeast 200 μg versus placebo daily for 48 months. Participation was 6 to 36 months postoperatively and required a negative mediastinal node biopsy, no excessive vitamin intake, normal liver function, negative chest x-ray, and no other evidence of recurrence. Results The first interim analysis in October 2009, with 46% of the projected end points accumulated, showed a trend in favor of the placebo group with a low likelihood that the trial would become positive; thus, the study was stopped. One thousand seven hundred seventy-two participants were enrolled, with 1,561 patients randomly assigned. Analysis was updated in June 2011 with the maturation of 54% of the planned end points. Two hundred fifty-two SPTs (from 224 patients) developed, of which 98 (from 97 patients) were lung cancer (38.9%). Lung and overall SPT incidence were 1.62 and 3.54 per 100 person-years, respectively, for selenium versus 1.30 and 3.39 per 100 person-years, respectively, for placebo (P = .294). Five-year disease-free survival was 74.4% for selenium recipients versus 79.6% for placebo recipients. Grade 1 to 2 toxicity occurred in 31% of selenium recipients and 26% of placebo recipients, and grade ≥ 3 toxicity occurred in less than 2% of selenium recipients versus 3% of placebo recipients. Compliance was excellent. No increase in diabetes mellitus or skin cancer was detected. Conclusion Selenium was safe but conferred no benefit over placebo in the prevention of SPT in patients with resected NSCLC. PMID:24002495

    We describe the clinical course and have characterised anatomically and genetically a unique case of a newborn with bilateral hypoplasia of pulmonary arteries, consecutive extremely hypoplastic lung tissue and associated unilateral renal agenesis. Intrauterine oxygenation by the placenta seemed to have allowed normotrophic body maturity but immediately after delivery, in the third trimester, progressive hypoxemia developed and the newborn succumbed to acute respiratory failure. Genetic analysis by array-based comparative genomic hybridisation and quantitative PCR revealed duplication of 1p21, which, however, might not be the disease causing aberration. This case might represent an extreme form of previously reported, rare cases with simultaneous dysorganogenesis of lungs and kidneys.

    Lobectomy with lymph node dissection has long been the standard surgical procedure for non-small cell lung cancer.However,the increased identification of smaller and smaller and even more indolent tumors by advanced imaging screening rekindled the interest of sublobar resection.Still,existing evidence only supports sublobar resection for radiologically or pathologically "very-early" stage tumors or high-risk patients.Ongoing randomized controlled trials in America,Japan and Europe will address the issue of " radical" application of sublobar resection,as well as an elderly patient trial for " compromized" application initiated by us.These efforts will delineate the utility of sublobar resection in patients with nonsmall cell lung cancer.%肺叶切除加淋巴结清扫多年来是非小细胞肺癌的标准术式,但随着影像学技术发展,越来越多小肺癌,特别是以磨玻璃样表现为主的“惰性”肺癌被发现,亚肺叶切除又受到重视.然而,现有的证据仅仅支持其用于治疗影像学提示或病理证实的极早期肺癌.为了真正明确亚肺叶切除的地位,目前国际上开展了几项随机对照试验,包括美国、日本和欧洲的“根治性”研究,和我国的老年患者“妥协性”研究.希望这些研究的成果能彻底回答肺癌亚肺叶切除的地位问题.

    Full Text Available Background and objective Lung cancer is the leading cause of cancer death in men and women in the world, more than one-half of cases are diagnosed at a advanced stage, and the overall 5-year survival rate for lung cancer is 18%. Lung cancer is divided into non-small cell lung carcinoma (NSCLC and small cell lung carcinoma (SCLC. Approximately 80%-85% of cases are NSCLC which includes three main types: adenocarcinoma (40%, squamous cell carcinoma (SCC (20%-30%, and large cell carcinoma (10%. Although therapies that target driver mutations in adenocarcinomas are showing some promise, they are proving ineffective in smoking-related SCC. We need pay more attention to the diagnosis and treatment of SCC. 18F-FDG positron emission tomography (PET/computed tomography (CT has emerged as an accurate staging modality in lung cancer diagnosis. The aim of this study is to investigate the role of maximum standardized uptake value (SUVmax on PET-CT in prognosis and its correlation with clinicopathological characteristics in resectable SCC. Methods One hundred and eighty-two resectable SCC patients who underwent PET/CT imaging between May 2005 and October 2014 were enrolled into this retrospectively study. All the enrolled patients had underwent pulmonary resection with mediastinal lymph node dissection without preoperative chemotherapy or radiotherapy. Survival outcomes were analyzed using the Kaplan-Meier method and multivariate Cox proportional hazards model. Correlation between SUVmax and clinicopathological factors was analysed using Pearson correlation analysis and Spearman rank correlation analysis. Results The patients were divided into two groups on the basis of SUVmax 13.0 as cutoff value, and patients with SUVmax more than 13.0 had shorter median overall survival than patients less than 13.0 in univariate analysis (56 months vs 87 months; P=0.022. There was remarkable correlation between SUVmax and gender, tumor size, tumor-node-metastasis (TNM stage

Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases is hitherto controversial. Patients and methods: We retrospectively analyzed the cases of NSCLC patients with brain metastases who underwent neurosurgical resection at the Sun Yat-sen University Cancer Center, and assessed the efficacy of surgical resection and the necessity of aggressive treatment for primary NSCLC in synchronous brain metastases patients. Results: A total of 62 patients, including 47 men and 15 women, with brain metastases from NSCLC were enrolled in the study. The median age at the time of craniotomy was 54 years (range 29–76 years. At the final follow-up evaluation, 50 patients had died. The median OS time was 15.1 months, and the survival rates were 70% and 37% at 1 and 2 years, respectively. The median OS

    Background 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. Methods 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. Results 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. Conclusions 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. PMID:26941976

    Clamshell incision is a standard approach for bilateral lung transplantation, providing a good operative field; however, once wide dehiscence occurs, its management is sometimes difficult because of intense immunosuppression and malnutrition of the recipient. A 22-year-old man with idiopathic pulmonary arterial hypertension underwent cadaveric bilateral lung transplantation through a clamshell incision using standard cardiopulmonary bypass. He developed wound dehiscence on postoperative day (POD) 20 that resulted in exposure of the bilateral fifth ribs and open pneumothorax. Considering the extreme malnutrition and emaciation of the recipient, we avoided initial closure of the dehiscence. After the debridement of necrotic tissue, negative pressure wound therapy was initiated on POD 25 and was continued for approximately 6 months with trafermin spray application. Eventually, the wound, including the fifth ribs, was completely covered with granulation tissue except for the wire tying the sternum. On POD 217, the patient underwent removal of the sternal wire followed by split-thickness skin grafting. His wound was successfully closed and he was discharged without activity limitation on POD 265.

    Full Text Available This study was conducted to investigate whether a panel of eight genetic polymorphisms can predict the prognosis of patients with early stage non-small cell lung cancer (NSCLC after surgical resection.We selected eight single nucleotide polymorphisms (SNPs which have been associated with the prognosis of lung cancer patients after surgery in our previous studies. A total of 814 patients with early stage NSCLC who underwent curative surgical resection were enrolled. The association of the eight SNPs with overall survival (OS and disease-free survival (DFS was analyzed.The eight SNPs (CD3EAP rs967591, TNFRSF10B rs1047266, AKT1 rs3803300, C3 rs2287845, HOMER2 rs1256428, GNB2L1 rs3756585, ADAMTSL3 rs11259927, and CD3D rs3181259 were significantly associated with OS and/or DFS. Combining those eight SNPs, we designed a prognostic index to predict the prognosis of patients. According to relative risk of death, a score value was assigned to each genotype of the SNPs. A worse prognosis corresponded to a higher score value, and the sum of score values of eight SNPs defined the prognostic index of a patient. When we categorized the patients into two groups based on the prognostic index, high risk group was significantly associated with worse OS and DFS compared to low risk group (aHR for OS = 2.21, 95% CI = 1.69-2.88, P = 8.0 x 10-9, and aHR for DFS = 1.58, 95% CI = 1.29-1.94, P = 1.0 x 10-5.Prognostic index using eight genetic polymorphisms may be useful for the prognostication of patients with surgically resected NSCLC.

    Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative. An antiparaneoplastic antibody panel was positive for anti-Hu antibodies. This led to an endobronchial biopsy of a paratracheal lymph node, which confirmed the diagnosis of small cell lung cancer. Conclusion. Paraneoplastic neuropathy is a rare cause of BVCP and should be considered when more common pathologies are ruled out. This is the second reported case of BVCP as a presenting symptom of paraneoplastic syndrome secondary to small cell lung cancer. PMID:27668114

    Full Text Available Background and objective Postoperative radiotherapy (PORT after complete resection of non-small cell lung cancer (NSCLC has been introduced in order to reduce locoregional recurrence, but it remains controversy whether PORT can improve survival. Therefore, we want to investigate the effect of PORT and the relationship between failure patterns and primarily location of stage IIIA (N2 in NSCLC. Methods This retrospective analysis included 233 patients who underwent resection of NSCLC, first recurrence involving a local-regional site. It illustrated the factors affecting local recurrence and the sites of failure on the basis of lobe of primary tumor. Results Multivariable analysis demonstrated the number of positive lymph nodes (P=0.003, T stage (P<0.001, histological type (P=0.038, modus operandi (P=0.013 and the number of mediastinal lymph node stations involved (P=0.018 were the independent factors. For all patients, the most common site of failure was the bronchial stump/staple line, which was present more often in those who had a wedge resection than in those who had a more radical procedure (P<0.001. The local-region frequency of squamous was higher than adenocarcinoma carcinoma (P=0.025. The recurrence frequency of mediastinal lymph node among T1 and T2-3 were 36.4%, 62.0% (P=0.009 respectively. The localregion recurrence among primarily tumor location were different. Conclusion The number of positive lymph nodes, T stage, histological type, modus operations and the number of mediastinal lymph node stations involved were the independent factors in IIIA (N2 NSCLC.

    Biomarkers can help to identify patients with early-stages or locally advanced non-small cell lung cancer (NSCLC) who have high risk of relapse and poor prognosis. To correlate the expression of seven biomarkers involved in DNA synthesis and repair and in cell division with clinical outcome, we consecutively collected 82 tumour tissues from radically resected NSCLC patients. The following biomarkers were investigated using IHC and qRT-PCR: excision repair cross-complementation group 1 (ERCC1), breast cancer 1 (BRCA1), ribonucleotide reductase subunits M1 and M2 (RRM1 and RRM2), subunit p53R2, thymidylate synthase (TS), and class III beta-tubulin (TUBB3). Gene expression levels were also validated in an available NSCLC microarray dataset. Multivariate analysis identified the protein overexpression of RRM2 and TS as independent prognostic factors of shorter overall survival (OS). Kaplan-Meier analysis showed a trend in shorter OS for patients with RRM2, TS, and ERCC1, BRCA1 overexpressed tumours. For all of the biomarkers except TUBB3, the OS trends relative to the gene expression levels were in agreement with those relative to the protein expression levels. The NSCLC microarray dataset showed RRM2 and TS as biomarkers significantly associated with OS. This study suggests that high expression levels of RRM2 and TS might be negative prognostic factors for resected NSCLC patients. PMID:26663950

    Pleural dissemination was proved by intraoperative histodiagnosis in 11 of 121 patients who underwent pulmonary resection for non-small cell carcinoma of the lung between April, 1985 and December, 1986. To control such intrathoracic residual diseases, we devised a means of local thermo-chemotherapy. Ten of 11 patients were treated with intrapleurally administrated cisplatin (50-100mg, bolus) combined with simultaneous radiofrequency hyperthermia (13.56 MHz) for 2 to 3 weeks after surgery. Courses were repeated at 5-to 7-day intervals. Eight patients had N2-disease, one N1 and the other NX. Eight were adenocarcinomas. Thermal burn of the chest wall with hyperkalemia was observed in only one patient who received thermotherapy at the over a magnetrode power of 450 watts for 50 minutes. In the other 9, side effects were minimal under the thermotherapy to obtain a peripleural temperature beyond 42 degrees C. Of the 10 patients, three lived more than 12 months after treatment. Although distant metastases were recognized in 6 cases, none had local recurrence for the median follow-up period of 6 months. One patient had metastasis to the contralateral supraclavicular lymph nodes. Because there was no evidence of intrathoracic recurrences in this patient, radical neck dissection were performed 15 months after the initial operation. This experience warrants further investigation of thermo-chemotherapy as a treatment for controlling pleural dissemination after resection of primary tumor.

    We analysed the results of radical segmentectomy achieved through a hybrid video-assisted thoracic surgery (VATS) approach that used both direct vision and television monitor visualization at a median follow-up of over 5 years. Between April 2004 and October 2010, 102 consecutive patients able to tolerate lobectomy to treat clinical T1N0M0 non-small cell lung cancer (NSCLC) underwent hybrid VATS segmentectomy in which we used electrocautery without a stapler to divide the intersegmental plane detected by selective jet ventilation in addition to the path of the intersegmental veins. Curative resection was achieved in all patients. The median surgical duration and blood loss during the surgery were 129 min (range, 60-275 min) and 50 ml (range, 10-350 ml), respectively. The complication rate was 9.8% (10/102) with the most frequent being prolonged air leak, and there was no case of in-hospital death or 30-day mortality post procedure. Five and seven patients developed locoregional and distant recurrences, respectively. The overall and disease-free 5-year survival rates were 89.8% and 84.7%, respectively. Radical hybrid VATS segmentectomy including atypical resection of (sub)segments is a useful option for clinical stage-I NSCLC. The exact identification of anatomical intersegmental plane followed by dissection using electrocautery is critical from oncological and functional perspectives.

    Introduction While retrospective analyses support an association between early tumor recurrence and tumor suppressor gene (TSG) promoter methylation in early-stage non-small cell lung cancers (NSCLCs), few studies have investigated this question prospectively. Methods Primary tumor tissue from patients with resected pathologic stage I-IIIA NSCLCs was collected at the time of surgery and analyzed for promoter methylation via methylation-specific reverse-transcriptase polymerase chain reaction (MethyLight). The primary objective was to determine an association between promoter methylation of 10 individual TSGs (CDKN2A, CDH13, RASSF1, APC, MGMT, GSTP1, DAPK1, WIF1, SOCS3, and ADAMTS8) and recurrence-free survival (RFS), with the secondary objectives of determining association with overall survival (OS), and relation to clinical or pathologic features. Results 107 patients had sufficient tumor tissue for successful promoter methylation analysis. Majority of patients were former/current smokers (88%) with lung adenocarcinoma (78%) and pathologic stage I disease (66%). Median follow-up was 4 years. When controlled for pathologic stage, promoter methylation of the individual genes CDKN2A, CDH13, RASSF1, APC, MGMT, GSTP1, DAPK1, WIF1, and ADAMTS8 was not associated with RFS. Promoter methylation of the same genes was not associated with OS except for DAPK1 which was associated with improved OS (p=0.03). The total number of genes with methylated promoters did not correlate with RFS (p=0.89) or OS (p=0.55). Conclusions Contrary to data established by previous retrospective series, TSG promoter methylation (CDKN2A, CDH13, RASSF1,APC, MGMT, GSTP1, DAPK1, WIF1, and ADAMTS8) was not prognostic for early tumor recurrence in this prospective study of resected NSCLCs.

    Full Text Available We aimed to reveal the true status of epidermal growth factor receptor (EGFR mutations in Chinese patients with non-small cell lung cancer (NSCLC after lung resections. EGFR mutations of surgically resected fresh tumor samples from 697 Chinese NSCLC patients were analyzed by Amplification Refractory Mutation System (ARMS. Correlations between EGFR mutation hotspots and clinical features were also explored. Of the 697 NSCLC patients, 235 (33.7% patients had tyrosine kinase inhibitor (TKIs sensitive EGFR mutations in 41 (14.5% of the 282 squamous carcinomas, 155 (52.9% of the 293 adenocarcinomas, 34 (39.5% of the 86 adenosquamous carcinomas, one (9.1% of the 11 large-cell carcinomas, 2 (11.1% of the 18 sarcomatoid carcinomas, and 2 (28.6% of the 7 mucoepidermoid carcinomas. TKIs sensitive EGFR mutations were more frequently found in female patients (p < 0.001, non-smokers (p = 0.047 and adenocarcinomas (p < 0.001. The rates of exon 19 deletion mutation (19-del, exon 21 L858R point mutation (L858R, exon 21 L861Q point mutation (L861Q, exon 18 G719X point mutations (G719X, including G719C, G719S, G719A were 43.4%, 48.1%, 1.7% and 6.8%, respectively. Exon 20 T790M point mutation (T790M was detected in 3 squamous carcinomas and 3 adenocarcinomas and exon 20 insertion mutation (20-ins was detected in 2 patients with adenocarcinoma. Our results show the rates of EGFR mutations are higher in all types of NSCLC in Chinese patients. 19-del and L858R are two of the more frequent mutations. EGFR mutation detection should be performed as a routine postoperative examination in Chinese NSCLC patients.

    Full Text Available Abstract Background Lung transplantation (LTx is widely accepted as a therapeutic option for end-stage respiratory failure in cystic fibrosis. However, airway complications remain a major cause of morbidity and mortality in these patients, serious airway complications like bronchopleural fistula (BPF are rare, and their management is very difficult. Case presentation A 47-year-old man with end-stage respiratory failure due to cystic fibrosis underwent bilateral sequential lung transplantation. Severe post-operative bleeding occurred due to dense intrapleural adhesions of the native lungs. He was re-explored and packed leading to satisfactory haemostasis. He developed a bronchopleural fistula on the 14th post-operative day. The fistula was successfully repaired using pericardial and intercostal vascular flaps with veno-venous extracorporeal membrane oxygenator (VV-ECMO support. Subsequently his recovery was uneventful. Conclusion The combination of pedicled intercostal and pericardial flaps provide adequate vascular tissue for sealing a large BPF following LTx. Veno-venous ECMO allows a feasible bridge to recovery.

    The aim of this study was to explore the effects of presurgical exercise training on quality of life (QOL) in patients with malignant lung lesions. Using a single-group prospective design, patients were enrolled in supervised aerobic exercise training for the duration of surgical wait time (mean 59.7 days). Participants completed assessments of cardiorespiratory fitness (peak oxygen consumption) and QOL using the Functional Assessment of Cancer Therapy-Lung scales, including the trial outcome index (TOI) and the lung cancer subscale (LCS) at baseline, immediately presurgery, and postsurgery (mean, 57 days). 9 participants provided complete data. Repeated-measures analysis indicated a significant effect for time on TOI (P = .006) and LCS (P = .009). Paired analysis revealed that QOL was unchanged after exercise training (ie, baseline to presurgery), but there were significant and clinically meaningful declines from presurgery to postsurgery in the LCS (-3.6, P = .021) and TOI (-8.3, P = .018). Change in peak oxygen consumption from presurgery to postsurgery was significantly associated with change in the LCS (r = 0.70, P = .036) and TOI (r = 0.70, P = .035). Exercise training did not improve QOL from baseline to presurgery. Significant declines in QOL after surgery seem to be related to declines in cardiorespiratory fitness. A randomized controlled trial is needed to further investigate these relationships.

    Full Text Available Nucleolin is implicated to play a role in angiogenesis, a vital process in tumor growth and metastasis. However, the presence and clinical relevance of nucleolin in human non small cell lung cancer (NSCLC remains largely unknown. In this study, we explored the expression and prognostic implication of nucleolin in surgically resected NSCLC patients. A cohort of 146 NSCLC patients who underwent surgical resection was selected for tissue microarray. In this tissue microarray, nucleolin expression was measured by immunofluorescence. Staining for CD31, a marker of endothelial cells, was performed to mark blood vessels. A Cox proportional hazards model was used to assess the prognostic significance of nucleolin. Nucleolin expression was observed in 34.2% of all patients, and 64.1% in high CD31 expression patients. The disease-free survival (DFS was significantly shorter in patients with high nucleolin (CD31(hiNCL(hi compared to patients with low tumor blood vessels (CD31(loNCL(lo (5 ys of DFS 24% vs 64%, p = 0.002. Such a difference was demonstrated in the following stratified analyses: stage I (p<0.001, squamous cell carcinoma and adenosquamous cell carcinoma (p = 0.028, small tumor (<5 cm, p = 0.008, and surgery alone (p = 0.015. Multivariate analysis further revealed that nucleolin expression independently predicted for worse survival (p = 0.003. This study demonstrates that nucleolin is associated with the clinical outcomes in postoperative NSCLC patients. Thus, the expression levels of nucleolin may provide a new prognostic marker to identify patients at higher risk for treatment failure, especially in some subgroups.

    Purpose Although numerous studies have demonstrated associations between the preoperative neutrophil-to-lymphocyte ratio (NLR) and long-term outcomes in patients with non-small cell lung cancer (NSCLC), the prognostic significance of postoperative NLR and change in NLR (ΔNLR) is unknown for patients who underwent complete resection of stage I NSCLC. The aim of this retrospective study was to evaluate the prognostic significance of postoperative NLR and ΔNLR in 123 patients with stage I NSCLC. Patients and methods This retrospective study included preoperative and postoperative data of 123 patients who underwent surgical resection for stage I NSCLC. The relationship between disease-free survival (DFS), overall survival (OS), and clinicopathological factors, including NLR, lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio, and their changes, was analyzed using both univariate Kaplan–Meier and multivariate Cox regression methods. Results The 5-year DFS and OS rates in our cohort were 60.16% and 67.48%, respectively. Univariate analysis revealed that age (P=0.045), smoking status (P=0.033), preoperative NLR (P=0.032), postoperative NLR (P<0.001), ΔNLR (P=0.004), and change in LMR (ΔLMR) (P=0.025) were significant predictors of DFS and that age (P=0.039), smoking status (P=0.042), postoperative NLR (P<0.001), ΔNLR (P=0.004), and ΔLMR (P=0.011) were independent predictors of OS. Multivariate analysis confirmed that postoperative NLR (hazard ratio [HR] =2.435, P=0.001) and ΔNLR (HR =2.103, P=0.012) were independent predictors of DFS and that postoperative NLR (HR =2.747, P=0.001) and ΔNLR (HR =2.052, P=0.018) were significant prognostic factors of OS. Conclusion Our study reported for the first time that postoperative NLR and ΔNLR – but not preoperative NLR – were independent prognostic factors of DFS and OS in patients with stage I NSCLC who underwent complete resection. This easily available biomarker might be helpful in individual risk

    The prognosis of non-small cell lung cancer (NSCLC) remains poor and heterogeneous and new biomarkers are needed. As the immune system plays a pivotal role in cancer, the study of immune-related markers may provide valuable prognostic information of NSCLC. In 122 formalin-fixed, paraffin-embedded tumor tissue samples from early-stage NSCLC, tumor and tumor-near stromal areas were microdissected and gene expression levels of conventional and regulatory T cell markers were assessed by quantitative polymerase chain reaction. Also, the presence of infiltrating CD4+, CD8+, and FOXP3+ cells in tumor samples was assessed by immunohistochemistry. The relative proportion of conventional and regulatory T cells present in the tumor environment was assessed and found to be key to understand the importance that the immune system analysis has in the prognostics of NSCLC patients. The presence of CD8+ cells in the tumor compartment was associated with better outcome, whereas the presence of FOXP3+ cells was associated with worse overall survival. The negative prognostic value of combined biomarkers, indicating high levels of FOXP3 in the stroma and low levels of CD4 or CD8 in tumors, was observed at mRNA level and was validated by immunohistochemistry.In conclusion, the proportion of T helper and cytotoxic cells vs. regulatory T cells in different locations of the tumor microenvironment have opposite prognostic impacts in resected NSCLC.

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    We report the development of spinal infarction during adjuvant chemotherapy with tegafur, gimeracil and oteracil (TS-1) after surgery for lung adenocarcinoma. A 69-year-old female had a left upper lobectomy for pulmonary adenocarcinoma, T2aN0M0. Six weeks after the surgery, tegafur, gimeracil and oteracil were administered orally as adjuvant chemotherapy for 1 year. After 10 months of adjuvant chemotherapy, the patient suddenly showed signs of numbness and weakness in both lower limbs. The patient did not have a previous medical history, and was receiving only tegafur, gimeracil and oteracil with the stomach medication. Neurological findings showed muscle weakness, numbness and a loss of tendon reflex in both lower limbs, as well as bladder and rectal disturbance. Blood tests, brain magnetic resonance imaging and chest computed tomography showed no signs of abnormalities or metastasis. Magnetic resonance imaging of the spine showed a hyperintense lesion between the Th12 and L1 spinal levels by T2-weighted image. A spinal fluid test indicated no abnormalities, and cytological diagnosis was class II. Anti-aquaporin 4, anti-ganglioside and anti-neuronal autoantibodies were all negative. These results indicated that the patient had a spinal infarction, rather than myelitis or paraneoplastic neurological syndrome. The patient was treated with heparin and steroid pulse treatment followed by rehabilitation, and recovered sufficiently to be able to walk using a cane after 2 months. The development of spinal infarction during anti-cancer chemotherapy has not been previously reported. In this case, an association of spinal infarction with the use of adjuvant chemotherapy was strongly indicated due to the lack of abnormalities in coagulability, atherosclerotic lesions and aortic disease.

    Background The outcome of surgical treatment of non-small-cell lung cancer (NSCLC) remains poor. In many patients the biological behavior of NSCLC does not follow a definite pattern, and can not be accurately predicted before treatment. 18F-fluoro-2-deoxy-glucose (18F-FDG) uptake on positron-emission tomography (PET) is associated with the aggressiveness of NSCLC. The present study focused on the role of 18F-FDG uptake in predicting the outcome of surgically treated patients with NSCLC.Methods A retrospective analysis was made of 82 patients who underwent complete resection and preoperative FDG PET. The maximum standardized uptake value (SUVmax), in addition to five clinicopathological factors and three biomolecular factors, which could possibly influence survival, was compared for possible association with patients' recurrence and survival, by the Log-rank test in univariate analysis and the Cox proportional hazards model in multivariate analysis. The association between SUVmax and other factors was also analyzed. Results Patients with SUVmax more than 11 had a disease-free survival and overall survival shorter than patients with SUVmax less than 11 in univariate analyses (P<0.001, P=0.002). In the multivariate analysis, SUVmax (dichotomized by 11) was the only significant predictor for tumor recurrence. TNM stage and SUVmax (dichotomized by 11) were independent predictors for the overall survival. Associations of SUVmax with p53 overexpression, proliferating cell nuclear antigen (PCNA) labeling index and microvascular density of the tumor were significant in the entire group. Conclusions 18F-FDG uptake on PET may be used to noninvasively assess biological aggressiveness of NSCLC in vivo, identifying the surgically-treated patients with poor prognosis who could benefit from additional therapy.

    Risk assessment and treatment choice remain a challenge in early non-small-cell lung cancer (NSCLC). Alternative splicing is an emerging source for diagnostic, prognostic and therapeutic tools. Here, we investigated the prognostic value of the actin cytoskeleton regulator hMENA and its isoforms, hMENA11a and hMENAΔv6, in early NSCLC. The epithelial hMENA11a isoform was expressed in NSCLC lines expressing E-CADHERIN and was alternatively expressed with hMENAΔv6. Enforced expression of hMENAΔv6 or hMENA11a increased or decreased the invasive ability of A549 cells, respectively. hMENA isoform expression was evaluated in 248 node-negative NSCLC. High pan-hMENA and low hMENA11a were the only independent predictors of shorter disease-free and cancer-specific survival, and low hMENA11a was an independent predictor of shorter overall survival, at multivariate analysis. Patients with low pan-hMENA/high hMENA11a expression fared significantly better (P≤0.0015) than any other subgroup. Such hybrid variable was incorporated with T-size and number of resected lymph nodes into a 3-class-risk stratification model, which strikingly discriminated between different risks of relapse, cancer-related death, and death. The model was externally validated in an independent dataset of 133 patients. Relative expression of hMENA splice isoforms is a powerful prognostic factor in early NSCLC, complementing clinical parameters to accurately predict individual patient risk. PMID:25373410

    2016-01-01

    Background The predictive and prognostic value of carcinoembryonic antigen (CEA), cytokeratin-19 fragments (Cyfra21-1), squamous cell carcinoma antigen (SCCA) and neuron-specific enolase (NSE) has been investigated in non-small-cell lung cancer (NSCLC) patients. However, few studies have directly focused on the association between these markers and epidermal growth factor receptor (EGFR) mutation status or mutation subtypes. Patients and methods We retrospectively analyzed 1016 patients with stage I-IIIA NSCLC who underwent complete resection between 2008 and 2012. Correlations between serum tumor marker levels and EGFR mutations and survival parameters were analyzed and prognostic factors were identified. Results Cyfra21-1 levels (P = 0.032 for disease-free survival [DFS]; P < 0.001 for overall survival [OS]) and clinical stage were identified as independent predictive and prognostic factors in EGFR-mutated adenocarcinoma patients. CEA levels (P < 0.001 for DFS; P = 0.002 for OS) and clinical stage were independently predictive and prognostic in EGFR wild-type adenocarcinoma patients. Further stratification analysis revealed that in EGFR exon 19 deletion adenocarcinomas, elevated Cyfra21-1 was an independent prognostic factor (P = 0.002). Within the Leu858Arg substitution subgroup, increased CEA (P = 0.005) and clinical stage were predictive factors of DFS, while elevated CEA (P = 0.005) and Cyfra21-1 (P = 0.027) were independent prognostic factors. Conclusion Cyfra21-1 and CEA exhibit different predictive and prognostic values between EGFR-mutated and wild-type adenocarcinomas, as well as between EGFR mutation subtypes. The prognostic impact of preoperative serum tumor markers should be evaluated together with EGFR mutation status. PMID:27072585

    Full Text Available Background and objective Lung cancer with brain metastasis had poor prognosis. Crizotinib had been confirmed to be used in ROS1 (C-ros oncogene 1 receptor tyrosine kinase rearranged lung adenocarcinoma, but its efficacy in lung cancer with brain metastasis was poor due to the blood brain barrier. In the present study, we reported one case of ROS1 fusion lung adenocarcinoma with symptomatic brain matastasis, who was treated with brain metastases resection, crizotinib, and whole brain radiotherapy plus boost to residual brain metastasis. The safety and efficacy was summarized. Methods At first, surgical resection was used to relive mass effect and to biopsy. Then crizotinib (250 mg, bid was chosen for the existence of ROS1 fusion gene. Whole brain radiotherapy plus boost to residual brain metastasis were used after surgery. Objective response was evaluated by Response Evaluation Criteriation in Solid Tumours (RECIST v1.1 and brain metastasis were evaluated by computer tomography (CT/magnetic resonance imaging (MRI image. Adverse events were evaluated according to Common Terminology Criteria for Adverse Events (CTC AE v4.0. Results After taking crizotinib for 3 months, the lung lesions were close to complete response (CR, the brain metastasis were partial response (PR, the abdomen metastasis were CR and the symptom of blurred vision relieved. Conclusion Crizotinib combined with palliative operation and radiation therapy (WBRT plus boost to residual brain metastasis in the treatment of ROS1 fusion gene positive lung adenocarcinoma with symptomatic brain metastases, can effectively control intracranial lesions with good tolerance.

    Full Text Available BACKGROUND: The prognostic value of the copy number (GCN and protein expression of the mesenchymal-epithelial transition (MET gene for survival of patients with non-small cell lung cancer (NSCLC remains controversial. This study aims to comprehensively and quantitatively asses the suitability of MET GCN and protein expression to predict patients' survival. METHODS: PubMed, Embase, Web of Science and Google Scholar were searched for articles comparing overall survival in patients with high MET GCN or protein expression with those with low level. Pooled hazard ratio (HR and 95% confidence intervals (CIs were calculated using the random and the fixed-effects models. Subgroup and sensitivity analyses were also performed. RESULTS: Eighteen eligible studies enrolling 5,516 patients were identified. Pooled analyses revealed that high MET GCN or protein expression was associated with poor overall survival (OS (GCN: HR = 1.90, 95% CI 1.35-2.68, p<0.001; protein expression: HR = 1.52, 95% CI 1.08-2.15, p = 0.017. In Asian populations (GCN: HR = 2.22, 95% CI 1.46-3.38, p<0.001; protein expression: HR = 1.89, 95% CI 1.34-2.68, p<0.001, but not in the non-Asian subset. For adenocarcinoma, high MET GCN or protein expression indicated decreased OS (GCN: HR = 1.49, 95% CI 1.05-2.10, p = 0.025; protein expression: HR = 1.69, 95% CI 1.31-2.19, p<0.001. Results were similar for multivariate analysis (GCN: HR = 1.61, 95% CI 1.15-2.25, p = 0.005; protein expression: HR = 2.18, 95% CI 1.60-2.97, p<0.001. The results of the sensitivity analysis were not materially altered and did not draw different conclusions. CONCLUSIONS: Increased MET GCN or protein expression was significantly associated with poorer survival in patients with surgically resected NSCLC; this information could potentially further stratify patients in clinical treatment.

    Hypersexuality has occasionally been reported in patients with temporal lobe epilepsy following temporal lobe resection. The mechanism underlying this phenomenon is poorly understood. We describe seven patients who spontaneously reported dramatic postoperative changes in sexual behavior after unilateral temporal lobe resection. Five of the seven patients showed evidence of bilateral temporal lobe abnormalities. All of the patients had significant difficulties with postoperative psychosocial adjustment that preceded the onset of hypersexuality. Five of the patients were completely seizure-free and one reported postoperative auras. Recurrent complex partial seizures occurred at a reduced frequency in one patient after 6 months. In this patient, the period of seizure freedom did not directly correlate with the period of hypersexuality. These cases suggest that hypersexuality following unilateral temporal lobe resection is more likely to occur in the presence of psychosocial difficulties and contralateral temporal lobe abnormalities. Neurophysiological processes associated with seizure cessation alone do not appear to account for postoperative hypersexuality.

    Summary: This study describes a case report of a 31-year-old patient who presented with a left thoracic tumor on costal cartilages 5 and 6 that was diagnosed as a desmoid tumor 3 years after receiving retropectoral breast implants for cosmetic reasons. The integral reconstruction of the thoracic wall, functional and aesthetic, was planned for a single surgical period. The defect secondary to the tumor resection, which left the pericardium and lung exposed, was closed using the pectoral muscle as a “pre-expanded” flap by the breast implant, and the breast aesthetic was treated bilaterally with new implants in the retromammary position. After 12 months, the patient remained free from tumor recurrence and had a satisfactory aesthetic result. PMID:28280682

METHODS A retrospective analysis of our hospital since 2006 was conducted to investigate TUVP combined with bilateral testicular resection in the treatment of advanced prostate cancer patients before and after treatment, the summary and analysis of urodynamic and change of serum PSA. RESULTS 3 months after operation, urodynamic and serum levels of patients improved significantly after treatment, maximum urinary flow rate (M FR) after operation the differences in average urinary flow rate (A FR) and residual urine (ARV) before and after operation had significant differences (P < 0.05). Before surgery, 3 months after surgery, differences in serum prostate specific antigen (PSA) level had obvious statistical significance (P<0.05). CONCLUSION In advanced prostate cancer with urinary tract obstruction patients, electrovaporization of the prostate combined with bilateral testicular resection while giving androgen blockade therapy can significantly improve the quality of life of patients, delay disease progression.

    Primary ciliary dyskinesia (PCD) is characterized by the congenital impairment of mucociliary clearance. When accompanied by situs inversus, chronic sinusitis and bronchiectasis, PCD is known as Kartagener syndrome. The main consequence of impaired ciliary function is a reduced mucus clearance from the lungs, and susceptibility to chronic respiratory infections due to opportunistic pathogens, including nontuberculous mycobacteria (NTM). There has been no report of NTM lung disease combined with Kartagener syndrome in Korea. Here, we report an adult patient with Kartagener syndrome complicated with Mycobacterium abscessus lung disease. A 37-year-old female presented to our hospital with chronic cough and sputum. She was ultimately diagnosed with M. abscessus lung disease and Kartagener syndrome. M. abscessus was repeatedly isolated from sputum specimens collected from the patient, despite prolonged antibiotic treatment. The patient's condition improved and negative sputum culture conversion was achieved after sequential bilateral pulmonary resection.

    We report a case of double-lumen tube intubation and intraoperative one-lung ventilation under spontaneous breathing with continuous dexmedetomidine administration. A 61-year-old man developed pneumothorax due to multiple metastatic cancer, had multiple bilateral bullae, and underwent bullae resection under general anesthesia. An epidural catheter was placed at T8-9. Under dexmedetomidine sedation and regional anesthesia with lidocaine, a double-lumen tube was inserted with a Macintosh laryngoscope. The patient was under one-lung ventilation with spontaneous breathing during the operation. There were no complications from one-lung ventilation and the patient was extubated in the operating room. One-lung ventilation, which preserves spontaneous breathing, under dexmedetomidine sedation is considered effective for preventing barotrauma in patients with multiple metastatic cancer.

    Baroreflex failure after chemodectoma resection We present a case of baroreflex failure secondary to a unilateral injury of the glossopharyngeal nerve. The patient was operated for a left-sided chemodectoma in the carotid body. Some months after surgery she started to report presyncopal episodes exacerbated by mental stress and when standing up. During these episodes, the patient presented hypertensive crises and tachycardia. However, blood pressure was below normal ranges at rest. The diagnosis was baroreflex failure secondary to unilateral injury of the glossopharyngeal nerve. The case reported herein illustrates the fact that the presence of a bilateral injury is not essential for the occurrence of this disorder.

    2012-01-01

    Full Text Available Background and objective Massive hemoptysis was a rare but severe postoperative complication of lung cancer. The aim of the present study is to investigate the mechanisms, risk factors, early symptoms, prevention, and treatment options for fatal hemoptysis. Methods From April 2007 to May 2011, 1,737 patients with lung cancer were surgically treated in the West China Hospital of Sichuan University. Twenty patients died during the perioperative period, seven of whom died of massive hemoptysis. These seven cases were analyzed, and their clinical data, as well as related literatures, were reviewed. Results Massive hemoptysis is the second cause of death after lung cancer surgery. Six patients died directly of massive hemoptysis. One patient underwent secondary surgery because of massive hemoptysis, but eventually died because of lung infection and respiratory failure. Early symptoms of hemorrhage were observed in four cases, and the overall incidence rate of massive hemoptysis was 0.4% (7/1,737. Conclusion Bronchovascular fistula (BVF caused by bronchopleural fistula (BPF is the mechanism for massive hemoptysis. Diabetes is a high risk factor. Early diagnosis and surgical treatment of BPF or BVF can prevent the occurrence of death as a result of massive hemoptysis.

    Full Text Available BACKGROUND AND OBJECTIVES: Cryptogenic fibrosing pleuritis is an extremely rare disease, which can affect both lungs from a very young age. The most common finding is severe lung restriction resulting in both hypoxemic and ventilatory failure. CASE REPORT: Male patient, 26 year old with acute deterioration of chronic respiratory failure. Following admission prolonged mechanical ventilation was necessary. An atypical clinical presentation made the diagnosis difficult, but eventually cryptogenic fibrosing pleuritis and lung fibrosis were established. CONCLUSIONS: The prognostic outcome of patients with the final diagnosis of cryptogenic fibrosing pleuritis is extremely poor, especially in an advanced phase of this disease.

    To discuss the benefits and morbidity of and indications for colon resection during cytoreductive operations for ovarian cancer. The history of cytoreductive surgery for ovarian cancer is discussed, with special attention to the incorporation of colon resection. Literature regarding cytoreductive surgery for ovarian cancer is then reviewed, again with attention to the role of colon resection. The focus of the review is directed at broad technical considerations and rationales, for both primary and secondary cytoreduction. Over the past 15 to 20 years the standard cytoreductive operation for ovarian cancer has shifted from an abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy to an en bloc radical resection of the pelvic tumor and an omentectomy, and more recently to include increasing use of extensive upper abdominal surgery. En bloc pelvic resection frequently includes rectosigmoid resection, almost always accompanied by a primary anastomosis. Other portions of the colon are at risk for metastatic involvement and sometimes require resection in order to achieve optimal cytoreduction. The data regarding colon resection for the purpose of surgical cytoreduction of ovarian cancer are conflicting (in terms of benefit) and all retrospective. However, the preponderance of information supports a benefit in terms of survival when cytoreduction is clearly optimal. Similar to primary surgery, benefit from secondary cytoreduction of ovarian cancer occurs when only a small volume of disease is left behind. The preponderance of data suggests that colon resection to achieve optimal cytoreduction has a positive impact on survival. In order to better understand the role of colon resection as well as other extensive cytoreductive procedures for ovarian cancer, it will be important to continue to improve our understanding of prognostic variables such as the nuances of metastatic bowel involvement in order to better guide appropriate surgical management.

    Leong, S

    2010-06-19

    BACKGROUND: Inferior vena cava (IVC) filter insertion is a commonly performed procedure for indications such as recurrent pulmonary emboli or contraindication to anticoagulation. Symptomatic duplication of the IVC is exceedingly rare with only a handful of cases being described in the literature. AIM: We report an unusual case of a patient with symptomatic duplication of the IVC. RESULT: A 53-year-old woman presented at our hospital for resection of a cerebral metastasis from a non-small cell lung cancer following a recent diagnosis of bilateral lower limb deep venous thrombosis. This required perioperative reversal of anticoagulation and IVC filter insertion. Conventional venography performed during filter insertion documented the existence of a duplicated IVC. CONCLUSION: We present a case of a symptomatic duplication of the IVC requiring filter insertion. We review the developmental anatomy of the IVC along with the diagnostic findings and management strategies available.

    nutritional assessment methods. Objective: To study the rate of hyponutrition in patients candidates to lung resection in southern Galicia, and to determine if there were significant differences in the use of 2 different nutritional assessment methods. Patients and methods: 200 patients participated in this study: 144 males (aged 29-83 years and 56 females (aged 20-80 years. All of them were assessed for their nutritional status according to Chang's method and we also performed a patient-generated global subjective assessment (PG-GSA according to the SENBA working group protocol. Results: There is agreement between the 2 methods in assessing 122 patients as having "good nutritional status". There are two cases with agreement between both methods in the diagnosis of "moderate hyponutrition or risk for hyponutrition". No case of "severe hyponutrition" is diagnosed by the Chang's method. Conclusions: We found statistically significant differences between the observations obtained with the two methods. The Chang's method performed more accurately than the PG-GSA, so that we believe it should be the first choice method for the preoperative nutritional assessment of patients candidate to a lung resection.

    Full Text Available Therapies targeting EGFR are effective in treating tumors that harbor molecular alterations; however, there is heterogeneity in long-term response to these therapies. We retrospectively analyzed protein expression of EGFR, Stat3, phospho-Akt, and phospho-Erk1/2 by immunohistochemistry in a series of resected cases from a single institution, correlated with clinicopathological variables. There were 96 patients, with the majority of cases being of low stage tumors (17 pT1a, 23 pT1b, 30 pT2a, and 18 pT2b. Histologic subtypes were 45 acinar predominant, 2 cribriform, 25 solid, 7 papillary, 11 lepidic, and 4 mucinous tumors. The EGFR score was higher in tumors with vascular invasion (P=0.013, in solid and cribriform acinar histology, and in high stage tumors (P=0.006 and P=0.01. EGFR was more likely overexpressed in solid compared to lepidic tumors (P=0.02. Acinar tumors had the highest rate of ERK1/2 positivity (19%. There was a strong correlation among positivity for ERCC1 and other markers, including STAT3 (P=0.003, Akt (P=0.02, and ERK1/ERK2 (P=0.0005. Expression of molecules downstream to EGFR varied from 12% to 31% of tumors; however, the expression did not directly correlate to EGFR expression, which may suggest activation of the cascades through different pathways. The correlation of protein expression and the new lung adenocarcinoma classification may help in the understanding of activated pathways of each tumor type, which may act in the oncogenesis and drug resistance of these tumors.

  15. VATS intraoperative tattooing to facilitate solitary pulmonary nodule resection

    2008-03-01

    Full Text Available Abstract Introduction Video-assisted thoracic surgery (VATS has become routine and widely accepted for the removal of solitary pulmonary nodules of unknown etiology. Thoracosopic techniques continue to evolve with better instruments, robotic applications, and increased patient acceptance and awareness. Several techniques have been described to localize peripheral pulmonary nodules, including pre-operative CT-guided tattooing with methylene blue, CT scan guided spiral/hook wire placement, and transthoracic ultrasound. As pulmonary surgeons well know, the lung and visceral pleura may appear featureless on top of a pulmonary nodule. Case description This paper presents a rapid, direct and inexpensive approach to peripheral lung lesion resection by marking the lung parenchyma on top of the nodule using direct methylene blue injection. Methods In two patients with peripherally located lung nodules (n = 3 scheduled for VATS, we used direct methylene blue injection for intraoperative localization of the pulmonary nodule. Our technique was the following: After finger palpation of the lung, a spinal 25 gauge needle was inserted through an existing port and 0.1 ml of methylene blue was used to tattoo the pleura perpendicular to the localized nodule. The methylene blue tattoo immediately marks the lung surface over the nodule. The surgeon avoids repeated finger palpation, while lining up stapler, graspers and camera, because of the visible tattoo. Our technique eliminates regrasping and repalpating the lung once again to identify a non marked lesion. Results Three lung nodules were resected in two patients. Once each lesion was palpated it was marked, and the area was resected with security of accurate localization. All lung nodules were resected in totality with normal lung parenchymal margins. Our technique added about one minute to the operative time. The two patients were discharged home on the second postoperative day, with no morbidity. Conclusion

    Objective To determine whether re-expansion of the collapsed lung with room air can attenuate oxidative stress injury following one-lung ventilation during esophageal cancer resection. Methods Twenty-four ASA Ⅰ or Ⅱ patients aged 40-60 yr weighing 44-65 kg undergoing esophageal cancer resection were randomly divided into 2 groups (n=12 each) : room air group and pure oxygen group. Anesthesia was induced with midazolam, fentanyl, etomidate and atracurium and maintained with propofol and atracurium infusion and intermittent iv boluses of fentanyl. Right or left side double-lumen catheter (Fr 35, 37, 39) was inserted in each patient. Correct placement was verified by fiber-optic bronchoscopy. The patients were mechanically ventilated ( V_T 7-10 ml/kg, RR 12-16 bpm, FiO_2 1.0 during one-lung ventilation). P_(ET)CO_2 was maintained at 35-45 mm Hg. SpO_2 was maintained at 95%-100% during one-lung ventilation. Blood samples were collected at the beginning of one-lung ventilation (T_1 ), immediately before re-expansion of the collapsed lung (T_2) and 30 rain after re-expansion of the collapsed lung (T_3) for determination of serum levels of MDA, SOD and plasma level of protein carbonyl. Arterial blood samples were obtained at 2 h after operation for blood gas analysis. Results The plasma protein carbonyl level and serum MDA level were significantly increased while the serum SOD level was significantly decreased at T_3 as compared with thost at T_1 and T_2 in pure oxygen group. No significant change in serum levels of MDA, SOD and plasma level of protein carbonyl occurred during operation in room air group. The oxygenation index was significantly higher at 2 h after operation in room air group than in pure oxygen group. Conclusion Re-expansion of the collapsed lung with room air can attenuate the oxidative stress injury following one-lung ventilation during esophageal cancer resection.%目的 评价空气肺复张对食管癌根治术患者单肺通气后肺组织氧

    Background It is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.Methods We reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2±12.5) years and the mean left ventricular ejection fraction was (57.4±11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1±11.2) months).Results Fifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n=7), aortic valve replacement (n=3), mitral valve replacement (n=3), mitral valve replacement with coronary artery bypass grafting (n=1) and left atrial myxoma resection (n=1). Neoplastic resection consisted of lung cancer resection (n=5). colonic cancer resection (n=3), gallbladder resection (n=1), colonic cancer resection with gallbladder resection (n=1), hysterectomy (n=2), hysterectomy with bilateral salpingo-oophorectomy (n=2) and left ovariectomy (n=1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).Conclusions Simultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

    Objective To investigate the curative effects of GnRH-a assisted laparoscopic resection for bilateral ovarian endome-triosis cyst and its influence on the second pregnancy. Methods 64 cases of bilateral ovarian endometriosis cyst were randomly select-ed and divided into the intervention group (n=34) and the conventional group (n=30). The intervention group was given GnRH-a 3. 75 mg injection for 2 weeks, then underwent laparoscopic excision for endometriosis cyst, while the conventional group was not giv-en any pretreatment and simply given laparoscopic surgical treatment, then the change of hormone levels and ovarian diameters were compared between the two groups after treatment, and both group received the follow-up for 1 year, then the pregnancy and cyst re-currence were compared. Results The FSH level of the intervention group were (8. 03+2. 11) mIU /mL, significantly lower than the conventional group, while the E2 and LH levels were higher than conventional group with significant difference (P<0. 05), normal o-vary diameter less than 2 cm accounted for 67. 65%, and ovarian volume was significantly reduced; after 1 year of follow-up, the cyst recurrence rate of the intervention group was 5. 88%, pregnancy rate was 63. 63%, and the postoperative pregnancy interval in-terval time was shortened with statistically significant difference compared with the conventional group (P<0. 05). Conclusion Appli-cation of GnRH-a before laparoscopic bilateral ovarian endometriosis cyst surgery can effectively reduce the influence on the ovarian re-serve function as much as possible and effectively protect the ovarian function for the patients who have the reproduction requirements.%目的:探讨GnRH-a辅助下腹腔镜双侧卵巢子宫内膜异位囊肿剔除术的临床疗效及对再妊娠的影响。方法随机选取双侧卵巢子宫内膜异位囊肿患者64例,随机分为干预组34例和常规组30例,干预组给予GnRH-a 3.75 mg 注射治疗2 w,随后再行腹腔

    Following the initial bilateral and subsequent unilateral, subdural grid- and depth electrode-based localization and resection, our patient has remained seizure-free 2 years after epilepsy surgery with marked improvement in her quality of life, as corroborated by her neuropsychological test scores. Our patient's clinical course is testament to the potential role for resective strategies in selected cases of intractable epilepsy associated with bifrontal injury. Reversal of behavioral deficits with frontal lobe epilepsy surgery such as in this patient provides a unique opportunity to further our understanding of the complex nature of frontal lobe function.

    Tracheobronchial disruption is uncommon in blunt chest trauma. Many of these patients die before reaching the hospital. In the majority of survivors diagnosis is occasionally delayed resulting in complications like airway stenosis and lung collapse. Thus it is important to have radiological follow up after severe thoracic trauma. Sleeve resection can be an excellent option to conserve lung tissue in delayed presentation of bronchial transection.

    Patient: Male, 41 Final Diagnosis: Olfactory neuroblastoma Symptoms: Left nasal obstruction • occasional left epistaxis • headache Medication: None Clinical Procedure: Nasal endoscopic examination • neck palpation • CT • bilateral endoscopic resection • MRI • PET-CT • postoperative radiotherapy Specialty: Otolaryngology Objective: Unusual clinical course Background: Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. Case Report: A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. Conclusions: To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    2015-01-01

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

    2012-03-01

    Curative treatment of Klatskin tumors by radical surgical procedures with surgical preparation distant to the tumor region results in 5-year survival rates of 30-50%. This requires mandatory en bloc liver resection and resection of the extrahepatic bile duct often together with vascular resection. Nevertheless, the ideal safety margin of 0.5-1 cm remote from the macroscopic tumor extensions cannot be achieved in all cases. Based on hilar anatomy the probability of an adequate safety margin is higher using extended right hemihepatectomy together with portal vein resection compared to left hemihepatectomy. However, due to severe atrophy of the left liver lobe solely left-sided hepatectomy is feasible in some patients. In cases of eligibility for both procedures right hemihepatectomy is preferentially used due to the higher oncological radicality if sufficient liver function is present. Postoperative hepatic insufficiency and bile leakage after demanding biliary reconstruction, often with several small orifices, contribute to the postoperative complication rate of this complex surgical disease pattern.

    1994-01-01

    A retrospective study of mandibular resections performed from 1980 to 1984 was conducted to evaluate age, sex, aetiology, etc. The number of mandibular resections appears to have declined at the Institute of Stomatology and Maxillofacial Surgery of the Pitié-Salpêtrière Hospital. Different factors are involved included early diagnosis, improved surgical techniques and better patient follow-up. Partial mandibular resections are increasingly performed (52% of the cases) compared with total resections. Finally, a better understanding of the pathologies involved, especially tumours, has led to an adaptation of the resection techniques to avoid extensive mutilations.

    2012-01-01

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present.

    Julia G. Lyon

    2016-02-01

    Full Text Available Inflammatory myofibroblastic tumors (IMT are rare tumors of the respiratory tract that most commonly occur in the lung and are rarely seen in the trachea. They present most often in young patients. We report on a case of an IMT of the carina in a seven year old girl, requiring carinal resection and reconstruction with a novel technique in pediatric airway surgery. Attempts at endoscopic excision of the carinal IMT were unsuccessful. An open approach for resection of the involved carina, distal trachea, and proximal mainstem bronchi was performed via sternotomy and cardiopulmonary bypass. The resulting triangular defect in the trachea and bronchi was reconstructed with anastomosis of the proximal trachea and left mainstem bronchus using a rotational flap of the right lateral mainstem bronchial wall. The remaining right mainstem bronchus was anastomosed, end to side, to the intact trachea proximal to the primary anastomosis. Bronchoscopy and MRI 22 months post resection and reconstruction revealed a healthy neo-carina and patent distal airway with no evidence of recurrent IMT. Pediatric patients with carinal inflammatory myofibroblastic tumors can be successfully managed with open resection and reconstruction of the airway.

    • Gorlin syndrome (GS, also known as nevoid basal cell carcinoma syndrome (NBCCS, is a rare inherited multisystem disorder. This paper presents a 22-years-old Iranian woman with this syndrome whose past history was multiple keratocysts of maxillary bone. She was referred to gynecology clinic with the chief complaint of irregular menses and vaginal spotting. On examination, frontal bossing and hypertelorism were detected. Physical examination of genitalia disclosed bilateral adnexal masses. Pelvic ultrasound showed two solid, echogenous and calcified masses measuring 100*50*10 & 60*50*45 mm in the left and right ovaries, respectively. The patient underwent right oophorectomy and ovarian mass resection with preservation of intact ovarian tissue on the left side. On frozen and permanent histological sections, bilateral and calcified ovarian fibromas were diagnosed. Surprisingly, during the last follow-up one year after the surgery, we found that our patient was expecting a baby. It can be concluded that in the presence of bilateral and calcified ovarian fibromas, the possibility of GS should be considered. Accurate diagnosis is only possible with close attention to the familial and past medical history and physical examination. In these patients, careful follow up for detecting malignancies and other complications is highly recommended.

    Benign metastasizing leiomyoma (BML) usually are situated in one organ, most often in lungs. BML patients typically have a history of uterine leiomyoma treated with hysterectomy, myomectomy or subtotal hysterectomy. The aim of the study was to present the case of a 53-year-old woman with triple location in the lungs, parametria and appendix. She had undergone a myomectomy 26 years earlier. In 2015, she was admitted to the surgical department because of abdominal pain, whereupon a cholecystectomy was performed. CT scans showed pelvic mass with pulmonary metastasis. Upon discharge the patient was referred to the Gynecology Clinic, where a laparotomy was performed. The intraoperative findings were: 1) uterus with multiple leiomyomas, 2) four tumors in the parametria, 3) tumor connected to the appendix. A subtotal hysterectomy, with a bilateral salpingo-oophorectomy, removal of the tumors from the parametria and appendectomy was performed. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining (strongly positive for estrogen receptors and SMA, while Ki67 was very low, below 1%). Upon postoperative recovery, the patient was referred to the Thoracic Surgery Department. During the thoracotomy, multiple nodes, surrounded by lung parenchyma, were revealed. Wedge resection was performed, for localized pulmonary lesions, and sent for pathological examination. The final pathological diagnosis was benign metastasizing leiomyomatosis. In conclusion, the triple location of BML could possibly be a result of a parallel different metastasizing mechanism, although it is impossible to exclude one mechanism, which may be the cause of the metastases in three locations.

    Poor lung development was first noted on scintigraphy using sup(99m)Tc-phytate in 32 children. They had all been referred for a hepatosplenic scan but the initial circulatory phase of the radiopharmaceutical was also recorded as a routine procedure. In 3 patients it revealed aplasia of an entire lung; bilateral pulmonary hypolplasia was observed in 14 of 16 patients with diaphragmatic herniae. Six patients with congenital heart enlargement showed a poorly developed ipsilateral lung; 5 of 6 patients with dextrocardia without an intracardiac defect had a larger left lung compared with the right lung; both pulmonary beds appeared equal in a patient with mesocardia.

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

    Perihilar cholangiocarcinoma presents at the biliary and vascular junction of the hepatic hilum with a tendency to extend longitudinally into segmental bile ducts. Most patients show metastatic or unresectable disease at time of presentation or surgical exploration. In patients eligible for surgical resection, challenges are to achieve negative bile duct margins, adequate liver remnant function, and adequate portal and arterial inflow to the liver remnant. Surgical treatment is characterized by high rates of postoperative morbidity and mortality. This article reviews the various strategies and techniques, the role of staging laparoscopy, intraoperative frozen section, caudate lobectomy, and vascular reconstruction.

    Full Text Available Purpose: To report a case of bilateral primary intraocular lymphoma. Case report: A 33-year-old man presented with bilateral blurred vision since two years ago. Examination revealed large keratic precipitates, anterior chamber reaction, posterior subcapsular cataracts, and vitreous infiltration. After a short trial of topical and periocular steroids, diagnostic 25-gauge pars plana vitrectomy was performed and cytologic evaluation of the aspirate confirmed a diagnosis of intraocular lymphoma. The patient was subsequently managed with intravitreal methotrexate in both eyes and responded favorably. Central nervous system workup for lymphoma was negative. Conclusion: Primary intraocular lymphoma should be considered in young adults suffering from chronic recalcitrant panuveitis.

    Full Text Available Surgery plays a major role in the management of patients with lung cancer. Surgery is not only the main curative treatment modality in patients with early-stage lung cancer but it also has a significant role in the initial workup for the diagnosis and staging of lung cancer. This article describes the surgical management of patients with lung cancer. Surgical resection for lung cancer is still regarded as the most effective method for controlling the primary tumor, provided it is resectable for cure and the risks of the procedure are low. The 5-year survival rare following complete resection (R0 of a lung cancer is stage dependent [Table 1]. [1-3] Incomplete resection (R1, R2 rarely, if ever, cures the patient.

    Full Text Available Introduction. Femoral hernias are at high risk of strangulation due to the narrow femoral canal and femoral ring. This can lead to symptoms of obstruction or strangulation requiring emergency surgery and possible bowel resection. To our knowledge, there is only one previous published report of bilateral strangulated femoral hernia. We present our case of this phenomenon. Case Report. An 86-year-old woman presented with symptoms of small bowel obstruction. Examination revealed two tender lumps in the area of the femoral triangle. CT scan revealed bilateral femoral hernias. Both hernias were repaired and a small bowel resection on the right side was performed with side to side anastomosis. She made an uneventful recovery. Conclusion. Bilateral femoral hernias are a rare occurrence with only one reported case of bilateral strangulation. Our case highlights the importance of meticulous history taking and clinical examination as any delay in diagnosis will increase the risk of mortality and morbidity for the patient. Hernias should always be considered as a cause if one presents with symptoms of abdominal pain or obstruction.

    Objective To investigate the effects of different positions and one-lung ventilation modes on respiratory mechanics of patients during bilateral pulmonary surgery. Methods Analysis on 142 cases who underwent bilateral pulmonary surgery from June, 2007 to December, 2010. PIP,Pplat,Raw and Cdyn measures were continuous monitored by side stream spirometry while SpO2 and PETCO2 were observed on the Patient Monitor. After dual cavity bronchus vessel was fixed and different ventilation modes were applied, blood gas analyses were made after 10 min with patients in lateral positions. Results When patient was changed to a lateral position under double-lung ventilation and when one-lung ventilation mode was applied, PIP、PplatRaw increased while Cdyn decreased, and PH decreased while PETCO2 and PaCO2 increased with SpO2 and PaO2 decreasing( P < 0. 05 ). When a different ventilation mode was applied under double-lung ventilation, PIP, Pplat and Raw decreased while Cdyn increased, PH decreased while PaO2 、SpO2 、PaCO2、PETCO2 increased ( P <0. 05 );when 38 cases were applied with a different ventilation mode under one-lung ventilation, PIP, Pplat and Raw decreased significantly while Cdyn increased, PH,PaO2 and SpO2 increased while PaCO2 and PETCO2 decreased( P <0. 05 ). Conclusion Different positions and ventilation modes have great effect on respiratory mechanics of patients during bilateral pulmonary surgery, and appropriate ventilation modes can improve respiratory mechanics and prevent hypoxemia, hypercarbia and barotraumas to protect lungs.%目的 观察双侧肺同期手术中体位改变和单肺通气时对病人呼吸力学的影响.方法 选取我院2007年6月至2010年12月双侧肺同期手术病人142例,经气道旁路采用旁气流通气连续监测病人PIP、Pplat、Raw、Cdyn等呼吸力学指标,监测SpO2、PETCO2指标,分别在双腔支气管导管定位后,平卧改侧卧,单肺通气及改换通气方式后10 min抽取动

    Esthesioneuroblastoma, or olfactory neuroblastoma, is an uncommon malignant tumor arising in the upper nasal cavity. Surgical approaches to this and other sinonasal malignancies involving the anterior skull base have traditionally involved craniofacial resections. Over the past 10 years to 15 years, there have been advances in endoscopic approaches to skull base pathologies, including malignant tumors. In this study, we review our experience with purely endoscopic approaches to esthesioneuroblastomas. Between January 2005 and February 2012, 11 patients (seven men and four women, average age 53.3 years) with esthesioneuroblastoma were treated endoscopically. Nine patients presented with newly diagnosed disease and two were treated for tumor recurrence. The modified Kadish staging was: A, two patients (18.2%); B, two patients (18.2%); C, five patients (45.5%); and D, two patients (18.2%). All patients had a complete resection with negative intraoperative margins. Three patients had 2-deoxy-2-((18)F)fluoro-d-glucose avid neck nodes on their preoperative positron emission tomography-CT scan. These patients underwent neck dissections; two had positive neck nodes. Perioperative complications included an intraoperative hypertensive urgency and pneumocephalus in two different patients. Mean follow-up was over 28 months and all patients were free of disease. This series adds to the growing experience of purely endoscopic surgical approaches in the treatment of skull base tumors including esthesioneuroblastoma. Longer follow-up on larger numbers of patients is required to clarify the utility of purely endoscopic approaches in the management of this malignant tumor.

    A 68-year-old male with a tracheostoma due to hypopharyngeal cancer was admitted because his chest computed tomography (CT) showed a small nodule in the right middle lobe. Following a partial resection of the right middle lobe, histopathological diagnosis of the resected sample was that of organizing pneumonia. Eleven months later, chest CT showed a mass with pleural indentation and spiculation in the right middle lobe. 18-Fluorodeoxyglucose-positron emission tomography showed significant accumulation in the middle lobe tumor mass shadow. The abnormal chest shadow that had developed around surgical staples suggested inadequate resection and tumor recurrence. As the abnormal radiological shadow was enlarging, middle lobectomy was carried out. Histological examination revealed that the tumor was a lung abscess without malignant features. This is a unique case of lung abscess mimicking lung cancer which developed around staples used during partial resection of the lung.

    2011-08-01

    Full Text Available Abstract Less than 1% of lung neoplasms are represented by benign tumors. Among these, hamartomas are the most common with an incidence between 0.025% and 0.32%. In relation to the localization, hamartomas are divided into intraparenchymal and endobronchial. Clinical manifestation of an endobronchial hamartoma (EH results from tracheobronchial obstruction or bleeding. Usually, EH localizes in large diameter bronchus. Endoscopic removal is usually recommended. Bronchotomy or parenchimal resection through thoracotomy should be reserved only for cases where the hamatoma cannot be approached through endoscopy, or when irreversible lung functional impairment occurred after prolonged airflow obstruction. Generally, when endoscopic approach is used, this is through rigid bronchoscopy, laser photocoagulation or mechanical resection. Here we present a giant EH occasionally diagnosed and treated by fiberoptic bronchoscopy electrosurgical snaring.

    2014-01-01

    Management of subepithelial tumors(SETs) remains challenging. Endoscopic ultrasound(EUS) has improved differential diagnosis of these tumors but a definitive diagnosis on EUS findings alone can be achieved in the minority of cases. Complete endoscopic resection may provide a reasonable approach for tissue acquisition and may also be therapeutic in case of malignant lesions. Small SET restricted to the submucosa can be removed with established basic resection techniques. However, resection of SET arising from deeper layers of the gastrointestinal wall requires advanced endoscopic methods and harbours the risk of perforation. Innovative techniques such as submucosal tunneling and full thickness resection have expanded the frontiers of endoscopic therapy in the past years. This review will give an overview about endoscopic resection techniques of SET with a focus on novel methods.

    2015-09-01

    Full Text Available Epithelioid sarcoma is a rare soft tissue sarcoma and usually resistant to chemotherapy. It has high rates of local recurrence and distant metastasis, and the prognosis after metastasis is poor. We report a case of multiple lung metastases of an epithelioid sarcoma originating in the inguinal area that we treated with the multikinase inhibitor pazopanib. The patient was a 38-year-old male who began to experience discomfort in his left inguinal area. Magnetic resonance imaging showed a tumor extended from the medial aspect of the wing of the left ilium along the iliopsoas muscle to its site of insertion on the femur. The histopathological diagnosis with a biopsy was proximal-type epithelioid sarcoma. Although a positron emission tomography examination showed fluorodeoxyglucose accumulation in the left inguinal tumor, there was no distant metastasis. Wide resection by a combined iliac resection procedure was performed. Twelve months after surgery, computed tomography revealed multiple nodules and a diagnosis of bilateral multiple lung metastases was made. Treatment with pazopanib 800 mg was started. After 2.5 months of treatment, a clear reduction in the size of the pulmonary metastases was shown. Thirty months after the start of pazopanib treatment, most of the metastases have disappeared, and no development of new lesions has been seen. Therefore, it appeared that pazopanib was capable of serving as one of the choices of therapeutic agents that should be taken into consideration for the treatment of advanced epithelioid sarcoma.

    62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. Conclusion The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival. PMID:25568802

    Full Text Available Este trabalho visou à ressecção de fragmento dorsocaudal do lobo pulmonar caudal esquerdo com o auxílio de sutura mecânica por via toracoscópica. Foram utilizados 10 eqüinos clinicamente sadios, os quais foram sedados e mantidos em estação. O procedimento foi realizado no hemitórax esquerdo, por três acessos previamente programados: o primeiro acesso foi no 12º espaço intercostal (EIC, o segundo no 14º, 15º ou 16º EIC e o terceiro no 14º ou 15º EIC, conforme a necessidade de posicionamento dos instrumentos. Em todos os animais foi possível controlar o pneumotórax, sendo observada evolução clínica satisfatória durante o período pós-operatório, exceto em um animal. Os resultados obtidos indicam que, por meio da videotoracoscopia, pode-se realizar ressecção pulmonar parcial com uso de sutura mecânica em eqüinos e seu emprego na rotina hospitalar poderá contribuir para melhor compreensão e controle de enfermidades sediadas na cavidade torácica.In this study, a dorsocaudal portion resection of the left caudal lung lobe was performed using an endoscopic stapler by thoracoscopic procedure. Ten healthy horses, eight males and two females were evaluated by clinical examination and submitted to the surgical procedure. The animals were sedated and maintained in standing position. The procedure was done in the left hemitorax using three access previously studied: the first portal was done at the 12th intercostal space (IS; the second one at the 14th, 15th, or 16th IS; and the third one at the 14th or 15th IS, in accordance with the necessity of positioning the instruments. The employed surgical technique seemed to be adequate in all animals, since it helped controlling the existing pneumothorax; furthermore, clinical recovery during the postoperative period was satisfactory, except for one animal. These results suggest that thoracoscopic may successfully be employed for partial lung resection in horses, using endoscopic

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012....... Univariate and multivariate analyses were performed to determine the relationship between retreatment of bCSDH and clinical, radiological, and surgical variables. RESULTS Two hundred ninety-one patients with bCSDH were identified, and 264 of them underwent unilateral (136 patients) or bilateral (128 patients...

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    Petit's lumbar hernia is an uncommon defect of the posterior abdominal wall that represents less than 1% of all abdominal wall hernias. It is more often unilateral and founded in young females, rarely containing a real herniated sac. There are two different approaches to repair: laparoscopy and open surgery. The goal of this article is to report one case of spontaneous bilateral lumbar Petit's hernia treated with open surgery.

    Increased incidence of tendinitis and tendon ruptures is reported in recipients of a kidney transplant. Two cases of bilateral achilles tendon rupture after minimal trauma are described. Tendon ruptures are more frequent in individuals with kidney disease in dialysis or after transplantation...... compared with patients receiving other organ transplantations. It is therefore more likely that tendon ruptures are related to metabolic changes associated with kidney disease rather than with transplantation or with glucocorticoid treatment per se. Clinical symptoms of achilles tendinitis should...

    Breast cancer is the most common malignancy in women. The most frequent metastatic sites are lung, bone, liver and brain. On the other hand, gastric metastases are rare. Synchronous bilateral breast cancer (SBBC) occurs rarely. Lobular carcinoma is the histological type most often associated with bilateral breast carcinomas and gastric metastases. We made a retrospective study including four patients followed in the Salah Azaiez Institute, for a bilateral breast cancer with gastric metastases. We analyzed the epidemiological, anatomoclinical and therapeutic particularities of this rare entity. Symptoms were unspecific. The diagnosis of gastric metastasis of the SBBC was confirmed by a histopathological examination of an endoscopic biopsy. The median age was 46.2 years (range, 36–51 years) and the median time until the gastric involvement was 19 months (range, 0–41 months). None of patients had a surgical treatment for the gastric location. All Patients received at least one line of chemotherapy and radiotherapy. Median survival following the detection of gastric involvement was 22 months (range, 1–56 months). Gastric metastases from breast cancer are rare and frequently associated with other distant metastasis. Symptoms are unspecific and endoscopy may not be contributive. Therefore, gastric involvement is underestimated. Lobular infiltrating carcinoma (LIC) is the most histological type incriminated in its occurrence. The supply of immunohistochemistry is crucial to distinguish between primary or metastatic gastric cancer. PMID:28280631

    Full Text Available Background and objective Localization of pulmonary ground glass nodule is the technical difficulty of minimally invasive operation resection. The aim of this study is to evaluate the value of computed tomography (CT-guided Hook-wire precise localization in resection of pulmonary nodules by video-assisted thoracoscopic surgery (VATS as well as to discuss the necessity and feasibility of surgical resection of GGOs through a minimally invasive approach. Methods CT-guided Hook-wire precise localization and wedge resection was done on 25 cases with 26 pulmonary nodules by VATS from May 2013 to June 2015. The efficacy of localization was evaluated in terms of procedure time, VATS success rate, and associated complications of localization. Results All the 26 pulmonary nodules (6 solid nodules and 20 GGOs of 25 patients (10 males and 15 females were preoperatively detected and localized with Hook-wire under CT guidance. Nodule diameters ranged from 5 mm-20 mm (mean: 8 mm. The distance of lung lesions from the nearest pleural surfaces ranged within 5 mm-30 mm (mean: 14 mm. All resections of lesions guided by the Hook-wire were successfully performed by VATS (success rate: 100%. The mean procedure time for the CT-guided Hook-wire localization was 10 min (range: 5 min-10 min. The mean procedure time for VATS wedge resection was 20 min (range: 15 min-40 min. The mean hospital time was 4 d (range: 3 d-6 d. The major complication of CT-guided Hook-wire localization was mild pneumothorax in 4 patients, but no one needed chest tube drainage. Wedge resection was performed successfully in all cases. The dislocation of Hook-wire was found in only one patient during the operation, but the lesion was still successfully resected under VATS. Results of pathological examination of 16 mGGOs revealed 8 primary lung cancers and 8 nonspecific chronic inflammations. Results of pathological examination of 4 pGGOs revealed 1 primary lung cancers, 1 atypical adenomatous

    Lung cancer invading the superior vena cava (SVC) is a locally advanced condition, for which poor prognosis is expected with conservative treatment alone. Surgical resection of the lesion can rapidly relieve the symptoms and significantly improve survival for some patients. Replacement, repair and partial resection of SVC via thoracotomy were generally accepted and used in the past. As the rapid development of minimally invasive techniques and devices, partial resection and repair of SVC are feasible via video-assisted thoracic surgery (VATS). However, few studies have reported the VATS surgical techniques. In this study, we reported the crucial techniques of partial resection of SVC via VATS. PMID:27076960

    We present a case of simultaneous bilateral spontaneous pneumothorax caused by a pleuro-pleural communication formed from Nuss procedure for pectus excavatum. A 17-year-old man with a history of Nuss operation complained chest pain and dyspnea. A chest roentgenogram demonstrated a tiny bilateral pneumothorax and two metallic bars inserted at the Nuss procedure. Computed tomography revealed furthermore a bulla in the apex of the left lung. The bilateral pneumothorax critically deteriorated after 4 days from onset and urgent bilateral chest drainages were performed. Nevertheless the drainages the full expansion of both lungs was not obtained and air leakage only from left side was continued. A video-assisted left bullectomy was performed 9 days after the tube insertion. The two bars penetrating anterior mediastinal pleura were thought to be a cause of the simultaneous bilateral spontaneous pneumothorax.

    @@ 1 Introduction The feasibility of colon resection using the laparoscope was demonstrated as early as 1991[1~3]. It was shown one year later that it is also possible to use the laparoscope in abdominoperineal resection of the rectum for rectal carcinoma[4, 5]. One year after this, the first study was reported in which the results of anterior resection with the laparoscope were compared with the conventional operation in a small number of patients with carcinoma of the rectum[6]. The first reports on the feasibility of total excision of the mesorectum in patients with carcinoma of the middle or lower third of the rectum were first published at the start of this century[7~9]. It can be stated in summary that resection of the colon or rectum using the laparoscope is not of disadvantage to the patient, given that the surgeon has appropriate experience and the patient has been properly selected.

    Bilateral optic neuropathy with bilateral putaminal lesions may be caused by methanol or cyanide poisoning or mitochondrial disorders including Leber hereditary optic neuropathy and Leigh syndrome. We report the case of a 34-year-old Japanese man who developed bilateral visual loss 5 days after the development of gastrointestinal symptoms. Magnetic resonance imaging of the brain on admission revealed high-intensity signal areas in the bilateral putamina on diffusion-weighted and T2-weighted images as well as a high-intensity signal area in the left middle cerebellar peduncle that had been identified 3 years previously. We diagnosed bilateral optic neuropathy with bilateral putaminal lesions caused by preceding infection-triggered demyelination. We administered methylprednisolone, but his vision did not recover.

    A-71-year-old man with sigmoid colon cancer underwent sigmoidectomy in 2004. Ascites cytology was positive. He had a postoperative chemotherapy, but cancer recurred on the Douglas' pouch in the first year after the surgery. After chemoradiation, he underwent a low anterior resection with combined resection of the prostate seminal vesicle urethra in 2005. Four years after the recurrence, metastasis of the right lung S9 occurred, and he underwent right lower lobectomy. One year later, metastasis of the left lung S6 occurred, he underwent a partial resection of S6. Later a local recurrence has not been observed. Among the colon cancer recurrence, we think the surgery was effective for local recurrence disease with adequate observation.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

  1. Transurethral resection of the ejaculatory duct.

    Paick, J S

    2000-05-01

    Complete bilateral ejaculatory duct obstruction has long been recognized as an uncommon, treatable form of male infertility. Partial ejaculatory duct obstruction reflects a disturbance of ejaculation where sperm quality is impaired during transit through the distal vas deferens and ejaculatory ducts. With the advent and increased use of high-resolution transrectal ultrasonography, abnormalities of the distal ejaculatory ducts related to infertility have been well documented. Although there are no pathognomonic findings associated with ejaculatory duct obstruction, several clinical findings are highly suggestive. In an infertile man with oligospermia or azoospermia with low ejaculate volume, normal secondary sexual characteristics, testes and hormonal profile and dilated seminal vesicles, midline cyst, or calcification on transrectal ultrasonography, ejaculatory duct obstruction is suggested. Of course, other causes of infertility may be concomitantly present and need to be searched for and treated as well. In selected cases, transurethral resection has resulted in marked improvement in semen parameters and pregnancies have been achieved. As is the case with all surgical procedures, proper patient selection and surgical experience are necessary to obtain optimal results. However, it appears that the treatments currently available for relief of ejaculatory obstruction are not optimally effective. Only approximately one half of treated patients will have an improvement in semen parameters and only about one quarter of treated patients will contribute to a pregnancy. What remains to be determined is how to manage the additional nearly 50% of patients who do not benefit from transurethral resection of ejaculatory obstruction. Based on my experience, I suggest that transrectal ultrasonography should be the first diagnostic procedure used when infertile men are suspected of having ejaculatory duct obstruction; however, vasography should still be considered for a more

    Background and purpose:The human Y-box binding protein, YB-1, is one of multifunctional proteins that regulates gene expression at both the transcriptional and translational levels. YB-1 has the potential to be used as a biomarker and predictor of multidrug resistance and prognosis in human cancers. This study was designed to detect YB-1 expression in lung adenocarcinoma by using immunohistochemical staining, and to evaluate the expression of YB-1 in patients with resected lung adenocarcinoma as well as its impact on their prognosis and recurrence. Methods:A total number of 174 lung adenocarcinoma patients who underwent surgical treatment were enrolled in this study. There were 99 men and 75 women with age of 65.0 years (range from 32 to 85). Immunohistochemical staining was done using by a streptavidin-biotin-peroxidase complex method (polyclonal anti-YB-1 antibody). The statistical significance was evaluated using the Pearson’s χ2 test. Survival curves were plotted according to the Kaplan–Meier method, and differences between the curves were analyzed by the log-rank test. The Cox proportional hazards model was applied to the univariate and multivariate survival analysis. Results:Positive expression of YB-1 was detected in the cytoplasm of tumor cells in 92 of 174 patients (52.9%) with lung adenocarcinoma. The positive expression of YB-1 was associated with poorly differentiated tumor (P=0.003), poor pathologic stage (P<0.001), lymph node metastasis (P=0.005) and tumor recurrence (P<0.001). The lung adenocarcinoma patients with positive YB-1 expression had a poorer prognosis than those with negative YB-1 expression, using both univariate and multivariate analyses (overall survival risk: P<0.001 and P=0.035, respectively). In addition, multivariate analysis of the clinicopathological characteristics with stageⅠlung adenocarcinoma indicated that the positive expression of YB-1 was a significant independent factor for predicting poor prognosis and early

    的预后中有意义(P=0.045)。结论 PET/CT SUVmax对肺鳞癌患者术后生存的预测有重要的价值,是独立于TNM分期之外的一个重要预后因素,并且原发灶SUVmax与多个临床病理因素间存在相关性。%Background and objective Lung cancer is the leading cause of cancer death in men and women in the world, more than one-half of cases are diagnosed at a advanced stage, and the overall 5-year survival rate for lung cancer is 18%. Lung cancer is divided into non-small cell lung carcinoma (NSCLC) and small cell lung carcinoma (SCLC). Approximately 80%-85%of cases are NSCLC which includes three main types:adenocarcinoma (40%), squamous cell carcinoma (SCC) (20%-30%), and large cell carcinoma (10%). Although therapies that target driver mutations in adenocarcinomas are showing some promise, they are proving ineffective in smoking-related SCC. We need pay more attention to the diagnosis and treatment of SCC. 18F-FDG positron emission tomography (PET)/computed tomography (CT) has emerged as an accurate staging mo-dality in lung cancer diagnosis. hTe aim of this study is to investigate the role of maximum standardized uptake value (SUVmax) on PET-CT in prognosis and its correlation with clinicopathological characteristics in resectable SCC. Methods One hun-dred and eighty-two resectable SCC patients who underwent PET/CT imaging between May 2005 and October 2014 were enrolled into this retrospectively study. All the enrolled patients had underwent pulmonary resection with mediastinal lymph node dissection without preoperative chemotherapy or radiotherapy. Survival outcomes were analyzed using the Kaplan-Meier method and multivariate Cox proportional hazards model. Correlation between SUVmax and clinicopathological factors was analysed using Pearson correlation analysis and Spearman rank correlation analysis. Results hTe patients were divided into two groups on the basis of SUVmax 13.0 as cutoff value, and patients with SUVmax more than 13.0 had shorter median

    Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.%目的:探讨淋巴结清扫数目对无淋巴结转移非小细胞肺癌患者预后的影响。方法:回顾性分析305例无淋巴结转移非小细胞肺癌患者临床病理资料。结果:全组患者中位生存期和5年生存率分别为60.0个月和47.1%。T分期、淋巴结清扫数目和清扫站数是影响本组患者预后的独立预后因素。相同T分期患者生存率随淋巴结清扫数目增加而增高(P0.05)。结论:淋巴结清扫数目是无淋巴结转移非小细胞肺癌患者预后的独立预后因素。术中应清扫足够数目的淋巴结,进而提高患者生存率。

    Purpose/Objectives: The aim of this study was to evaluate the impact of definitive thoracic chemoradiation therapy following surgery or stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) on the outcomes of patients with non-small cell lung cancer (NSCLC) with synchronous solitary brain metastasis (SSBM). Methods and Materials: A total of 63 NSCLC patients with SSBM were retrospectively evaluated. Patients were staged using positron emission tomography-computed tomography in addition to conventional staging tools. Thoracic radiation therapy (TRT) with a total dose of 66 Gy in 2 Gy fractions was delivered along with 2 cycles of cisplatin-based chemotherapy following either surgery plus 30 Gy of WBRT (n=33) or SRS plus 30 Gy of WBRT (n=30) for BM. Results: Overall, the treatment was well tolerated. All patients received planned TRT, and 57 patients (90.5%) were also able to receive 2 cycles of chemotherapy. At a median follow-up of 25.3 months (7.1-52.1 months), the median months of overall, locoregional progression-free, neurological progression-free, and progression-free survival were 28.6, 17.7, 26.4, and 14.6, respectively. Both univariate and multivariate analyses revealed that patients with a T1-T2 thoracic disease burden (P=.001), a nodal stage of N0-N1 (P=.003), and no weight loss (P=.008) exhibited superior survival. Conclusions: In the present series, surgical and radiosurgical treatments directed toward SSBM in NSCLC patients were equally effective. The similarities between the present survival outcomes and those reported in other studies for locally advanced NSCLC patients indicate the potentially curative role of definitive chemoradiation therapy for highly selected patients with SSBM.

    Purpose High dose definitive radiation therapy (RT) alone is recommended to patients with cT1-3N0 non-small cell lung cancer, who are unfit for surgery or stereotactic RT. This study was conducted to evaluate the clinical outcomes and cost-effectiveness following RT alone using two different modest hypofractionation dose schemes. Materials and Methods Between 2001 and 2014, 124 patients underwent RT alone. From 2001 till 2010, 60 Gy in 20 fractions was delivered to 79 patients (group 1). Since 2011, 60 Gy in 20 fractions (group 2, 20 patients), and 60 Gy in 15 fractions (group 3, 25 patients) were selectively chosen depending on estimated risk of esophagitis. Results At follow-up of 16.7 months, 2-year rates of local control, progression-free survival, and overall survival were 62.6%, 39.1%, and 59.1%, respectively. Overall survival was significantly better in group 3 (p=0.002). In multivariate analyses, cT3 was the most powerful adverse factor affecting clinical outcomes. Incidence and severity of radiation pneumonitis were not different among groups, while no patients developed grade 2 esophagitis in group 3 (p=0.003). Under current Korean Health Insurance Policy, RT cost per person was 22.5% less in group 3 compared with others. Conclusion The current study demonstrated that 60 Gy in 15 fractions instead of 60 Gy in 20 fractions resulted in comparable clinical outcomes with excellent safety, direct cost saving, and improved convenience to the patients with tumors located at ≥ 1.5 cm from the esophagus.

    Lung injury is the leading cause of death after thoracic surgery. Initially recognized after pneumonectomy, it has since been described after any period of 1-lung ventilation (OLV), even in the absence of lung resection. Overhydration and high tidal volumes were thought to be responsible at various points; however, it is now recognized that the pathophysiology is more complex and multifactorial. All causative mechanisms known to trigger ventilator-induced lung injury have been described in the OLV setting. The ventilated lung is exposed to high strain secondary to large, nonphysiologic tidal volumes and loss of the normal functional residual capacity. In addition, the ventilated lung experiences oxidative stress, as well as capillary shear stress because of hyperperfusion. Surgical manipulation and/or resection of the collapsed lung may induce lung injury. Re-expansion of the collapsed lung at the conclusion of OLV invariably induces duration-dependent, ischemia-reperfusion injury. Inflammatory cytokines are released in response to localized injury and may promote local and contralateral lung injury. Protective ventilation and volatile anesthesia lessen the degree of injury; however, increases in biochemical and histologic markers of lung injury appear unavoidable. The endothelial glycocalyx may represent a common pathway for lung injury creation during OLV, because it is damaged by most of the recognized lung injurious mechanisms. Experimental therapies to stabilize the endothelial glycocalyx may afford the ability to reduce lung injury in the future. In the interim, protective ventilation with tidal volumes of 4 to 5 mL/kg predicted body weight, positive end-expiratory pressure of 5 to 10 cm H2O, and routine lung recruitment should be used during OLV in an attempt to minimize harmful lung stress and strain. Additional strategies to reduce lung injury include routine volatile anesthesia and efforts to minimize OLV duration and hyperoxia.

    A 40-year-old woman with bilateral high radial nerve compressions by non-traumatic cause was reported. It occurred first at the right radial nerve which was explored after a period of investigation and conservative treatment. Two constricted sites 2.0 cm apart of the right radial nerve crossed by branches of the radial collateral artery beneath the lateral head of the triceps were found. The constricted sites including tissue in between was resected and replaced with a sural nerve graft. One year later the patient had the same episode on the left side. The operative finding was the same as the previous one. Sural nerve graft was performed after neurolysis had failed. The patient's normal radial nerve function returned in one year. This is the first reported case in the literature of bilateral high radial nerve compressions by branches of the radial collateral artery.

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    1985-04-01

    A 38-year-old man with brittle, juvenile onset diabetes mellitus and bilateral severe dry eyes with recurrent corneal ulcers developed atypical band-shaped calcifications of both corneas during a 24-hour period. Serum calcium, phosphate, and carbon dioxide levels all were within normal limits. The patient was mildly uremic but was not in renal failure. When EDTA chelation failed to clear the deposits, partial keratectomies were performed in both eyes and the specimens were examined by light and electron microscopy, including energy dispersive x-ray analysis. Microscopic studies revealed an atypical calcific keratopathy which involved neither Bowman's layer nor the most superficial stromal lamellae. The deposits were confined to deeper lamellae in the anterior stroma and by electron microscopy were composed of extracellular crystalline aggregates. Energy dispersive x-ray analysis of these aggregates confirmed the presence of calcium and phosphate. Corneal dessication appeared to be a major contributing factor in the rapid formation of these deposits.

    Full Text Available Introduction: Lung cancer metastasizing to the face has rarely been reported and is an even more unusual presentation. Case: This is the case of a 49-year-old man diagnosed with squamous cell carcinoma of the face, scheduled for resection. Preoperative radiographs revealed a left upper lobe mass, found to be squamous cell carcinoma. Diagnosis was changed to Stage IV primary lung cancer. The patient did not undergo resection. Discussion: No previous cases of primary lung cancer presenting as a malar mass have been reported. Facial lesions can be the presenting feature of primary lung cancer. Discovery of the true primary lesion can alter therapy and prognosis.

    Bilateral pulmonary agenesis (BPA) is a rare congenital lung malformation. The prognosis is severe as it is incompatible with extra-uterine life. Although multiple prenatal imaging modalities are developed, the prenatal diagnosis of BPA remains problematic. We report a case of BPA observed in our unity and for which the diagnosis was not clearly identified during the evaluation. This report illustrates the need to consider all the imaging aspects and particularly during US examination suspecting BPA.

    Full Text Available Inverted papilloma is an uncommon benign neoplasm originating from lateral nasal wall. It commonly invades paranasal sinuses and sometimes invasion to orbit and intracranial structures are seen. There are many surgical methods for its treatment, one of them is endoscopic transnasal approach."nMaterials and Methods: Between 1997 and 2001, 11 patients with this tumor were operated in Amiralam hospital in Tehran and Shahid Rahnemun in Yazd. Nine patients were operated by endoscopic transnasal route and two patients by combined Caldwell-luc and endoscopic transnasal routes."nResults: Tumors were on the right side in 3 patients, on the left side in 7 patients, and bilateral in one patient. There were no intracranial or orbital extensions. No pathologic report of malignancy was made. Surgical technique included complete tumor resection, anterior and posterior ethomidectomies, sphenoidectomy, frontal recess tumor resection and wide maxillary antrostomy, in cases in whom tumor was attached to lamina papyracea, the lamina was removed without any manipulation to orbital periosteum. Mean follow-up time was 29.8 months. There was no recurrence in 82% of cases. Tumor recurred in 18% of cases. No complications were seen."nConclusion: Although the standard treatment for this tumor is medial maxillectomy but endoscopic resection is an effective method in surgery of this tumor. It seems that if tumor does not extend to areas unreachable by endoscopic surgery, due to lower morbidity and excellent visualization of tumor, this method is preferable.

    Full Text Available Albeit a very large number of experiments have assessed the impact of various substrates on liver regeneration after partial hepatectomy, a limited number of clinical studies have evaluated artificial nutrition in liver resection patients. This is a peculiar topic because many patients do not need artificial nutrition, while several patients need it because of malnutrition and/or prolonged inability to feeding caused by complications. The optimal nutritional regimen to support liver regeneration, within other postoperative problems or complications, is not yet exactly defined. This short review addresses relevant aspects and potential developments in the issue of postoperative parenteral nutrition after liver resection.

    Purpose: To evaluate mediastinal nodal clearance (MNC) rates after induction chemotherapy and concurrent, full-dose radiation therapy (RT) in a phase II trimodality trial (Radiation Therapy Oncology Group protocol 0229). Patients and Methods: Patients (n=57) with stage III non-small cell lung cancer (pathologically proven N2 or N3) were eligible. Induction chemotherapy consisted of weekly carboplatin (AUC = 2.0) and paclitaxel 50 mg/m{sup 2}. Concurrent RT was prescribed, with 50.4 Gy to the mediastinum and primary tumor and a boost of 10.8 Gy to all gross disease. The mediastinum was pathologically reassessed after completion of chemoradiation. The primary endpoint of the study was MNC, with secondary endpoints of 2-year overall survival and postoperative morbidity/mortality. Results: The grade 3/4 toxicities included hematologic 35%, gastrointestinal 14%, and pulmonary 23%. Forty-three patients (75%) were evaluable for the primary endpoint. Twenty-seven patients achieved the primary endpoint of MNC (63%). Thirty-seven patients underwent resection. There was a 14% incidence of grade 3 postoperative pulmonary complications and 1 30-day, postoperative grade 5 toxicity (3%). With a median follow-up of 24 months for all patients, the 2-year overall survival rate was 54%, and the 2-year progression-free survival rate was 33%. The 2-year overall survival rate was 75% for those who achieved nodal clearance, 52% for those with residual nodal disease, and 23% for those who were not evaluable for the primary endpoint (P=.0002). Conclusions: This multi-institutional trial confirms the ability of neoadjuvant concurrent chemoradiation with full-dose RT to sterilize known mediastinal nodal disease.

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

    Full Text Available Aim: The aim of the study is to evaluate the cases who underwent tumor resection prosthesis due to osteosarcoma. Material and Method: 14 cases who underwent tumor resection prosthesis due to osteosarcoma in our clinic between 2000 and 2012 and who had sufficient follow-ups were evaluated. The cases were examined in terms of gender, age, direction, tumor location, follow-up time, success of the treatment, complication, recurrence, and survival. The data obtained were transferred to the SPSS 15.0 program and analyzed. Normality distributions of the data were analyzed with the Shapiro-Wilk test. Results: 8 of the 14 cases were male, 6 were female, and the average age of the cases was 21.9±7.02. Osteosarcoma was in the distal femur in 9 (64.3% of the patients, in the proximal tibia in 5 (35.7% of the patients, in the right lower extremity in 5 of the patients, and in the left lower extremity in 9 of the patients. Average follow-up time was 33 months (3-144 months range. Average MSTS score was found as 81.9 (53-96 range, perfect results were taken in 11 (78.6% patients while insufficient results were taken in 3 (21.4% patients. As for complications, aseptic softening was observed in 3 cases, peroneal nerve paralysis was observed in 2 cases, skin necrosis was observed in 2 cases, periprostatic fracture was observed in 2 cases, prosthesis infection was observed in 1 case, and local recurrence was observed in 1 case. Except for the two cases with peroneal nerve paralysis, cases with complications recovered without any problems. The patient who developed local recurrence was lost due to lung metastasis. Discussion: Treatment of osteosarcoma through tumor resection prosthesis raises question marks due to possible complications that can affect the survival of the prosthesis in the long term. However, this treatment method is favorable in terms of stability, early load efficiency, and causing less anxiety than osteosynthesis; it is also psychologically

    Synchronous gastric cancer and primary small intestinal lymphoma are extremely rare. A 49-year-old woman was referred to our hospital with a history of upper abdominal pain for two weeks and was diagnosed with synchronous cancer. During hospitalization, the patient underwent laparoscopic distal gastrectomy + resection of bilateral ovaries + partial resection of both small intestine and descending colon. Pathological examination revealed a synchronous cancer consisting of early gastric cancer with poorly differentiated adenocarcinoma located in mucosa, with lymph node metastasis (3+/29) (T1N1M0, stage IB); and diffuse large B cell lymphoma of small intestine involving descending colon and bilateral ovaries, with lymph node metastasis (2+/5) (Ann Arbor IIE). The patient recovered well, without any obvious complications and was discharged on post-operative day 7. The patient received six cycles of chemotherapy after operation. She has been doing well with no evidence of recurrence for 13 mo.

    Full Text Available Abstract Leiomyosarcoma of the inferior vena cava (IVCL is a rare retroperitoneal tumor. We report two cases of level II (middle level, renal veins to hepatic veins IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts. In our cases, IVCL is documented to be occluded preoperatively, therefore, radical resection of tumor and/or right kidney was performed and the distal end of inferior vena cava was resected and without caval reconstruction. None of the patients developed edema or acute renal failure postoperatively. After surgical resection, adjuvant radiation therapy was administrated. The patients have been free of recurrence 2 years and 3 months, 9 months after surgery, respectively, indicating the complete surgical resection and radiotherapy contribute to the better survival. The reconstruction of inferior vena cava was not considered mandatory in level II IVCL, if the retroperitoneal venous collateral pathways have been established. In addition to the curative resection of IVCL, the renal vascular reconstruction minimized the risks of procedure-related acute renal failure, and was more physiologically preferable. This concept was reflected in the treatment of the two patients reported on.

    Major problem in resecting liver parenchyma is how to control the bleeding. Recently, resection of the liver by water jet has been reported. So, experimental and clinical studies were performed to investigate the usefulness of the water jet equipment. Ten pigs weighing around 17kg were used. The optimal pressure to resect the porcine liver was 7 to 15kg/cm2. By 4 weeks the cut surface was covered with fibrous capsule. Portal angiography showed no abnormality in the resected area. The water jet was also used in 30 human operations. The optimal pressure was 12 to 18kg/cm2 for non cirrhotic liver and 15 to 20kg/cm2 for cirrhotic liver. The surface immediately after jet cutting was more smooth than that of CUSA and histologically there was slight bleeding and necrosis. The volume of blood loss during dissection was not different between water jet group and CUSA group. No significant changes were found in the laboratory data. These results suggest that water jet is as useful as CUSA for cutting the liver parenchyma.

    BACKGROUND:Pancreatic adenocarcinoma (PCa) is a disease with dismal prognosis, and the only possibility of cure, albeit small, is based on the combination of complete resection with negative histopathological margins (R0 resection) with adjuvant treatment. Therefore, a lot of effort has been made during the last decade to assess the role of extensive surgery in both local recurrence and survival of patients with PCa. DATA SOURCES:Medline search and manual cross-referencing were utilized to identify published evidence-based data for PCa surgery between 1973 and 2006, with emphasis to feasibility, efifcacy, long-term survival, disease free survival, recurrence rates, pain relief and quality of life. RESULTS: Extended surgery is safe and feasible in high volume surgical centers with comparable short-term results. Organ preserving surgery is a main goal because of quality of life reasons and is performed whenever possible from the tumor extent. Concerning long-term survival major vein resection does not adversely affect outcome. To date, there are no changes in long-term survival attributed to the extended lymph node dissection. However, there is a beneift in locoregional control with fewer local recurrences and extended lymphadenectomy allows better staging for the disease. CONCLUSIONS:Extended PCa surgery is safe and feasible despite the inconclusive results in patient's survival beneift. In the future, appropriately powered randomized trials of standard vs. extended resections may show improved outcomes for PCa patients.

    Full Text Available Surgical treatment of brain tumors, especially those located in the eloquent areas such as anterior temporal, frontal lobes, language, memory areas, and near the motor cortex causes high risk of eloquent impairment. Awake craniotomy displays major rule for maximum resection of the tumor with minimum functional impairment of the Central Nervous System. These case reports discuss the use of awake craniotomy during the brain surgery in Alzahra Hospital, Isfahan, Iran. A 56-year-old woman with left-sided body hypoesthesia since last 3 months and a 25-year-old with severe headache of 1 month duration were operated under craniotomy for brain tumors resection. An awake craniotomy was planned to allow maximum tumor intraoperative testing for resection and neurologic morbidity avoidance. The method of anesthesia should offer sufficient analgesia, hemodynamic stability, sedation, respiratory function, and also awake and cooperative patient for different neurological test. Airway management is the most important part of anesthesia during awake craniotomy. Tumor surgery with awake craniotomy is a safe technique that allows maximal resection of lesions in close relationship to eloquent cortex and has a low risk of neurological deficit.

    BACKGROUND: Pseudomonas aeruginosa cells are present as biofilms in the paranasal sinuses and the lungs of chronically infected cystic fibrosis (CF) patients. Since different inflammatory responses and selective antibiotic pressures are acting in the sinuses compared with the lungs, we compared......-lung transplantation isolates. RESULTS: The same phenotypes caused by similar mutations and similar gene expression profiles were found in mucoid and non-mucoid isolates from the paranasal sinuses and from the lungs before and after transplantation. CONCLUSION: Bilateral exchange of P. aeruginosa isolates between...... the paranasal sinuses and the lungs occurs in chronically infected patients and extensive sinus surgery before the lung transplantation might prevent infection of the new lung....

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    Mokra, Daniela; Kosutova, Petra

    2015-04-01

    Acute respiratory distress syndrome (ARDS) and its milder form acute lung injury (ALI) may result from various diseases and situations including sepsis, pneumonia, trauma, acute pancreatitis, aspiration of gastric contents, near-drowning etc. ALI/ARDS is characterized by diffuse alveolar injury, lung edema formation, neutrophil-derived inflammation, and surfactant dysfunction. Clinically, ALI/ARDS is manifested by decreased lung compliance, severe hypoxemia, and bilateral pulmonary infiltrates. Severity and further characteristics of ALI/ARDS may be detected by biomarkers in the plasma and bronchoalveolar lavage fluid (or tracheal aspirate) of patients. Changed concentrations of individual markers may suggest injury or activation of the specific types of lung cells-epithelial or endothelial cells, neutrophils, macrophages, etc.), and thereby help in diagnostics and in evaluation of the patient's clinical status and the treatment efficacy. This chapter reviews various biomarkers of acute lung injury and evaluates their usefulness in diagnostics and prognostication of ALI/ARDS.

    The harm associated with lung cancer treatment include perioperative morbidity and mortality and therapy-induced toxicities in various organs, including the heart and lungs. Optimal treatment therefore entails a need for risk assessment to weigh the probabilities of benefits versus harm. Exercise testing offers an opportunity to evaluate a patient's physical fitness/exercise capacity objectively. In lung cancer, it is most often used to risk-stratify patients undergoing evaluation for lung cancer resection. In recent years, its use outside this context has been described, including in nonsurgical candidates and lung cancer survivors. In this article we review the physiology of exercise testing and lung cancer. Then, we assess the utility of exercise testing in patients with lung cancer in four contexts (preoperative evaluation for lung cancer resection, after lung cancer resection, lung cancer prognosis, and assessment of efficiency of exercise training programs) after systematically identifying original studies involving the most common forms of exercise tests in this patient population: laboratory cardiopulmonary exercise testing and simple field testing with the 6-minute walk test, shuttle walk test, and/or stair-climbing test. Lastly, we propose a conceptual framework for risk assessment of patients with lung cancer who are being considered for therapy and identify areas for further studies in this patient population.

    Thoracic surgery remains the better therapeutic option for non-small cell lung cancer patients that are diagnosed in early stage disease. Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET). Vo2 peak, FEV1 and DLCO as well as recognition of performance status, presence of co-morbidities, frailty indexes, and age predict the potential impact of surgical resection on patient health status and survival risk. In this study we have retrospectively assessed the benefit of a high-intensity preoperative pulmonary rehabilitation program (PRP) in 14 patients with underlying lung function impairment prior to surgery. Amongst these, three patients candidate to surgical resection exhibited severe functional impairment associated with high score of frailty according CHS and SOF index, resulting in a substantial mortality risk. Our observations indicate that PRP appear to reduce the mortality and morbidity risk in frail patients with concurrent lung function impairment undergoing thoracic surgery. PRP produced improvement of VO2 peak degree and pulmonary function resulting in reduced postoperative complications in high-risk patients from our cases. Our results indicate that a preoperative training program may improve postoperative clinical outcomes in fraillung cancer patients with impaired lung function prior to surgical resection.

    Background The aim of this study is to discuss video-assisted thoracic surgery (VATS) sleeve bronchial lobectomy when handling the locally advanced central lung cancer (involving the trachea and/or main bronchus). Methods A 2.5 cm × 1.0 cm mass was found in the right upper lobe. Bronchoscopy demonstrated the tumor obstructing the right upper lobe bronchus and involved the right main bronchus and bronchus intermedius. Interrupted sutures were chosen for bronchial anastomosis. Bronchial membrane was sutured first, and then circumference end-to-end anastomoses were carried out using 3-0 absorbable sutures. Results There were no complications and the patient was discharged 8 days postoperatively. Conclusions The third intercostal space of the anterior axillary line was suggested for right upper lobe bronchial sleeve resection. This incision can reduce the distance and angle between the anastomosis to the incision, and facilitate anastomosis. This approach can also prevent operator from fatigue for keeping one posture for a long time. Clearance of the mediastinal lymph nodes before cutting the bronchus was helpful for exposing the right main bronchus, the upper lobe bronchus and bronchus intermedius satisfied. And this option would avoid pulling bronchial anastomosis during mediastinal lymph nodes clearance. Interrupted suture was safe and effective for VATS bronchial anastomosis. PMID:27621889

    Techniques in liver surgery have improved considerably during the last decades, allowing for liver resections with low morbidity and mortality. Preoperative patient selection, perioperative management, and intraoperative blood-sparing techniques are the cornerstones of modern liver surgery. Multimodal treatment of colorectal liver metastases has expanded the group of patients who are potential candidates for liver resection. Adjunctive techniques, including preoperative portal vein embolization and staged hepatectomy, have facilitated the safe performance of extensive liver resection. This article provides an overview of indications for liver resection and a systematic description of the technical approach to the most commonly performed resections.

    Full Text Available Laryngeal cancer takes the leading position among malignant tumors of head and neck. Currently, endolaryngeal laser resection is the leading treatment option for localized processes (T1-T2. In the period from December 2014 to January 2016 such surgeries were performed in 76 patients in our clinic. Carcinoma in situ was detected in 19 (25 %, T1a in 27 (35 %, T1b in 24 (31 %, T2 in 6 (8 % patients. As result of the planned histological examination, in all cases surgical procedures had microscopically radical character. Endolaryngeal CO2 -laser resections allow to perform enough large radical surgical interventions with satisfactory functional and cosmetic results, without compromising long-term outcomes.

    Thoracoscopic surgery can be one of less invasive surgical interventions for early stage lung cancer. Locally advanced lung cancer, however, cannot avoid aggressive procedures including pneumonectomy and/or extended combined resection of chest wall, aorta, esophagus, etc. for complete resection. Surgical approach even for advanced lung cancer can be less invasive by benefit from new anti-cancer treatment, innovated manipulations of bronchoplasty and angioplasty, and bench surgery( lung autotransplantation technique). We herein reviewed the strategy to minimize invasive interventions for locally advanced lung cancer, introducing 2 successful cases with advanced lung cancer. The 1st patient is a 62-year old man with centrally advanced lung cancer invading to mediastinum. Right upper sleeve lobectomy with one-stoma carinoplasty following induction chemoradiation therapy was successful. The operation time was 241 minutes. The performance status is good with no recurrence for 60 months after surgery. The 2nd is a 79-year old man with advanced lung cancer invading to the distal aortic arch. Left upper segmentectomy following thoracic endovascular aortic repair with stentgraft was successful with no extracorporeal circulation. The operation time was 170 minutes. The performance status is good with no recurrence for 30 months after surgery. The invasiveness of surgical interventions for local advanced lung cancer can be minimized by innovated device and new anti-cancer drugs.

    Full Text Available DNA double-strand breaks (DSBs, which arise following exposure to a number of endogenous and exogenous agents, can be repaired by either the homologous recombination (HR or non-homologous end-joining (NHEJ pathways in eukaryotic cells. A vital step in HR repair is DNA end resection, which generates a long 3′ single-stranded DNA (ssDNA tail that can invade the homologous DNA strand. The generation of 3′ ssDNA is not only essential for HR repair, but also promotes activation of the ataxia telangiectasia and Rad3-related protein (ATR. Multiple factors, including the MRN/X complex, C-terminal-binding protein interacting protein (CtIP/Sae2, exonuclease 1 (EXO1, Bloom syndrome protein (BLM/Sgs1, DNA2 nuclease/helicase, and several chromatin remodelers, cooperate to complete the process of end resection. Here we review the basic machinery involved in DNA end resection in eukaryotic cells.

    Placental transmogrification is a very rare lung disease, where the alveoli resemble the chorionic villi of placenta, and this change is a characteristic finding. A 31-year-old female patient presented with cough and dyspnea that had begun 2 weeks prior to admission. Along with giant bulla found in the left upper lung field, subsegmental consolidation was also identified in the lingular segment on plain chest radiograph and CT scan. Wedge resection was performed to remove the bulla. Pathologic examination of the resected bulla revealed destruction of the normal structures and characteristic villous and papillary changes. These changes led to a diagnosis of placental transmogrification. We made an encounter of an unusual placental transmogrification which had different image findings from other reported transmogrification cases. Thus, we report an atypical placental transmogrification case where both consolidation and giant bulla coexist.

Due to pulmonary tuberculosis, the patient had underwent a complete right-side pulmonary lobectomy 20 years ago. Left lung supports his life, he is unable to carry on an operation treatment, so he accepted radiotherapy. Firstly, we defined gross tumor volume (GTV1) by CT simulation location, three-dimensional conformal radiotherapy (3D-CRT) was used until tumor dose reached 50 Gy/25 f. Secondly, by repeating the planning CT scan, defined GTV2, continued to radiotherapy by 2.5 Gy/f until the dose was 65 Gy/31 f. Using the same method for third CT scan, defined GTV3, continued to radiotherapy by 3 Gy/f until the total dose was 74 Gy/34 f. After radiotherapy, the patient acquired complete response and he had no obvious side-effect of radiotherapy. There has been no recurrence for 5 years now.

  17. The Main Technical Points of Thoracoscopic Anatomical Lung Segment Resection

    Directory of Open Access Journals (Sweden)

    Liang CHEN

    2016-06-01

    Full Text Available Thoracoscopic segmentectomy is technically much more meticulous than lobectomy, due to the complicated anotomical variations of segmental bronchi and vessels. Preoperative three-dimensional computed tomography bronchography and angiography, 3D-CTBA could reveal the anatomical structures and variations of the segmental bronchi/vessels and locate the pulmonary nodules, which is helpful for surgery planning. Preoperative nodule localization is of vital importance for thoracoscopic segmentectomy. Techniques involved in this procedure include dissection of the targeted arteries, bronchus and intra-segmental veins, retention of the inter-segmental veins, identification of the inter-segmental boarder with the inflation-deflation method and seperation of intra-segmental pulmonary tissues by electrotome and/or endoscopic staplers. The incision margin for malignant nodules should be at least 2 cm or the diameter of the tumor. Meanwhile, sampling of N1 and N2 station lymph nodes and intraoperative frozen section is also necessary. The complication rate of thoracoscopic segmentectomy is comparatively low. The anatomic relationship between pulmonary segments and lobes is that a lobe consists of several irregular cone-shaped segments with the inter-segmental veins lies between the segments. Our center has explored a method to separate pulmonary segments from the lobe on the basis of cone-shaped principle, and we named it “Cone-shaped Segmentectomy”. This technique could precisely decide and dissect the targeted bronchi and vessels, and anatomically separate the inter-segmental boarder, which ultimately achieve a completely anatomical segmentectomy.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation. Mutiple radiological examinations detected bilateral adrenal atrophy. When the images were investigated in a more expanded scope, a 3.0×3.5×5.3 cm mass was detected in the anterior of left renal hilum and left renal vein. The mass was successfully resected with intraoperative endoscopy and pathological evaluation revealed an ectopic adrenal tumor. It is suggested that when the endocrinlogically confirmed adrenal neoplasm could not be well and definitely localized, the possibility of ectopic adrenal should be presumed and further radiography examinations should extend to the field where ectopic adrenal usually presents.

    This study evaluated the relationship between dose-volume histogram (DVH) parameters and pulmonary complications after neoadjuvant chemoradiotherapy (NACRT) followed by surgery for lung cancer. We also examined a new DVH parameter, because the unresected lung should be more spared than the later resected lung. Data from 43 non-small cell lung cancer patients were retrospectively analyzed. The DVH parameters of the lung were calculated from the total bilateral lung volume minus (1) the gross tumor volume (DVHg) or (2) the later resected lung volume (DVHr). Radiation pneumonitis (RP) and fistula, including bronchopleural and pulmonary fistula, were graded as the pulmonary complications. Factors affecting the incidences of grade 2 or higher RP (≥G2 RP) and fistula were analyzed. Sixteen patients (37 %) experienced ≥G2 RP and a V20 value of the total lung minus the later resected lung (V20r) ≥ 12 % was a significant factor affecting the incidence of ≥G2 RP (p = 0.032). Six patients (14 %) developed a fistula and a V35 value of the total lung minus the gross tumor (V35g) ≥ 19 % and a V40g ≥ 16 % were significant factors affecting the incidence of fistula (p = 0.002 and 0.009, respectively). These DVH parameters may be related to the incidences of ≥G2 RP and fistula. (orig.) [German] In dieser Studie wurde die Beziehung zwischen Dosis-Volumen-Histogramm-(DVH-)Parametern und pulmonalen Komplikationen nach neoadjuvanter Radiochemotherapie (NARCT) und nachfolgender Operation beim Lungenkarzinom untersucht. Zudem wurde ein neuer DVH-Parameter untersucht, da das nichtresezierte Lungengewebe mehr geschont werden sollte als reseziertes Gewebe. Daten von 43 Patienten mit nicht-kleinzelligem Bronchialkarzinom wurden retrospektiv analysiert.

    2009-07-01

    Pleuropulmonary blastoma (PPB) is an aggressive tumour accounting for less than 1% of all primary malignant lung tumours in the paediatric population. It can be associated with cystic pulmonary lesions, which may be evident at the time of diagnosis or predate the appearance of the tumour. There are contradictory reports about the value of prophylactic resection of pulmonary cysts in protecting patients from developing PPB. We report an individual case where asymptomatic congenital lobar emphysema was incidentally picked up on CXR. Following a period of surveillance the lesion was resected due to increasing size. The histology of the lesion revealed PPB Type I.

    Introduction: Nowadays an increasing number of lung resections are being done because of the rising prevalence of lung cancer that occurs mainly in patients with limited lung function, what is caused by common etiologic factor - smoking cigarettes. Loss of lung tissue in such patients can worsen much the postoperative pulmonary function. So it is necessary to asses the postoperative pulmonary function especially after maximal resection, i.e. pneumonectomy. Objective: To check over the accuracy of preoperative prognosis of postoperative lung function after pneumonectomy using spirometry and lung perfusion scinigraphy. Material and methods: The study was done on 17 patients operated at the Clinic for thoracic surgery, who were treated previously at the Clinic for Pulmonary Diseases “Podhrastovi” in the period from 01. 12. 2008. to 01. 06. 2011. Postoperative pulmonary function expressed as ppoFEV1 (predicted postoperative forced expiratory volume in one second) was prognosticated preoperatively using spirometry, i.e.. simple calculation according to the number of the pulmonary segments to be removed and perfusion lung scintigraphy. Results: There is no significant deviation of postoperative achieved values of FEV1 from predicted ones obtained by both methods, and there is no significant differences between predicted values (ppoFEV1) obtained by spirometry and perfusion scintigraphy. Conclusion: It is necessary to asses the postoperative pulmonary function before lung resection to avoid postoperative respiratory failure and other cardiopulmonary complications. It is absolutely necessary for pneumonectomy, i.e.. maximal pulmonary resection. It can be done with great possibility using spirometry or perfusion lung scintigraphy. PMID:23378687

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

    The lung transplantation program at the University of Alberta has been in existence for 25 years. The current volume is 35-40 new lung transplants per year. We offer single-lung, bilateral lung, heart/lung and bilateral living lobar transplantation as options. Experience has allowed for widening of the indications and acceptance of patients with more risk. Donor evaluation and management has allowed for extended donors to be included in the donor pool. Results will likely continue to improve with increased understanding of the mechanisms and management of bronchiolitis obliterans syndrome. Our research interests have been in the areas of risk analysis, outcome assessment, and quality of life changes from transplantation.

    Objectives: To compare the accuracy of prenatal ultrasonography (US) to magnetic resonance imaging (MRI) in the characterisation of congenital lung anomalies, and to assess their agreement with final diagnosis. To evaluate the influence of additional MRI information on therapeutic management. Methods: 26 prenatal congenital lung anomalies detected consecutively between 2006 and 2012 were retrospectively evaluated. Lesions were initially observed at prenatal US and further investigated with MRI. Prenatal US and MRI imaging findings, and suggested diagnosis were compared with the final diagnosis, obtained from autopsies (4), pathological evaluation following surgical resection (15) and postnatal imaging studies (7). Results: Postnatal diagnoses included 7 congenital pulmonary airway malformations, 8 complex lesions, 7 overinflations, 1 sequestration, 1 bronchogenic cyst, 1 blastoma and 1 bilateral lymphangioma. Suggested prenatal US and MRI diagnosis was correct in 34.6% and 46.2% of patients, respectively, mainly isolated lung lesions with typical imaging findings. Nonspecific imaging findings at US and MRI studies were observed in 38.4% of cases. In 42% of the operated anomalies, pathological dissection revealed the presence of complex anomalies. MRI changed the US diagnosis, but not the further management in 9.7% of the lesions. Conclusions: Prenatal US and MRI showed a high accuracy in the diagnosis of isolated congenital lung lesions with typical imaging findings. However, overall characterisation rates were low, because of both a high percentage of complex lesions and of lesions with nonspecific imaging findings. MRI was better than US in characterising complex lesions, but its additional information did not influence therapy decisions.

    The aim of the present study was to create a feasible specific rat model of isolated bilateral pulmonary contusion (PC) and to evaluate the relationship between severity of hypoxemia and quantity of contusion lesions. Anesthetized rats were placed in a prone position. Injury energy ranging from 2.1 to 3.0 J was produced by a falling weight passed through a specially designed arched shield to the bilateral chest wall of rats. After injury (4 h), the contusion volume was measured using computer-generated three-dimensional reconstruction from a chest computed tomographic scan and expressed as a percentage of total lung volume. Arterial partial pressure of oxygen (PaO(2)) in blood gas analysis and contusion volume percentage were used to assess the severity of contusion. Heart and lung biopsy was used to confirm the diagnosis and rule out the existence of myocardial contusion. There were 3 cases of death and 1 case of death in the 3.0 J and the 2.4 J group, respectively. PaO(2) in the 2.7 J group was significantly lower than that in the lower energy groups (Ppulmonary contusion in the 2.7 J group was significantly higher compared to that of the lower energy groups (Pcontusion percentage (R(2)=0.76). Hemorrhage, edema and neutrophil infiltration were determined by lung biopsy. No evidence of myocardial contusion was documented in multiple heart biopsies. The method illustrated in this research effectively duplicates isolated bilateral pulmonary contusion in rats, the severity of which is highly correlated with the contusion size. Thus, 2.7 J can be regarded as the maximal energy for sublethal injury.

    The coincidence of a gastrointestinal stromal tumor (GIST) and a neuroendocrine tumor (NET) in neurofibromatosis type 1 (NF1) is described only five times within the literature. We report on a 63 year old Caucasian female with the rare condition of neurofibromatosis type 1 coinciding with recurrent gastrointestinal stromal tumor plus bilateral pheochromocytoma (PCC). After a history of palpitations and dizziness that lasted for years, a left adrenal mass was detected by CT. Laparotomy revealed a pheochromocytoma of the left adrenal gland while an ileoterminal GIST was found incidentally intraoperatively.After six months contralateral PCC and multiple recurrent GIST were resected again. After four years the patient is doing well without any signs of further recurrent tumors.Discussion includes review of the literature.

    Bilateral spontaneous pneumothorax secondary to disease is rare and seldom encountered in forensic autopsies; however, traumatic bilateral pneumothorax occurs often. Herein, we present a forensic case involving a 50-year-old woman who died 4 days after ingesting a wristwatch. Postmortem computed tomography and autopsy findings demonstrated that the wristwatch was lodged at the pharyngoesophageal junction, that she had a bilateral pneumothorax unaccompanied by any thoracic wound, and that macular hemorrhagic lesions on the lung surfaces were responsible for the pneumothorax. A histological examination of the macular lesions revealed that they were aspiration pneumonia foci with many birefringent foreign materials. Furthermore, a necrotic process secondary to aspiration pneumonia with a one way check-valve hyperinflation caused by foreign materials in the bronchioles was the most probable pathogenesis of her pneumothorax. To our knowledge, this is the first reported case of a bilateral secondary spontaneous pneumothorax caused by a large foreign body at the pharyngoesophageal junction leading to death.

    2010-09-01

    Full Text Available Resectional lung volume reduction has proven to be superior to medical treatment in reducing dyspnoea and in increasing lung function, survival and quality of life in a very well selected, low risk group of hyperinflated patients with heterogeneous emphysema predominantly in the upper lobe. Nevertheless, this intervention is hampered by an important pulmonary (30% and cardiovascular (20% morbidity, mainly as a result of prolonged (>7 days air leak, and a 5% risk of death as a result of the surgical intervention. Results from ongoing randomised trials are awaited in order to determine whether less invasive, non-resectional lung volume treatment of emphysema via the bronchoscope using endobronchial valves, airway bypass stents or biological adhesives/heated water vapour will yield similar improvement with less morbidity and reduced mortality, compared with surgical resection. Furthermore, it is hoped that endoscopic lung volume reduction techniques may help patients with homogeneous emphysema currently excluded by most teams for the resectional procedure.

    OBJECTIVES En bloc pulmonary and chest wall resection is the preferred method of treatment for locally invasive lung carcinoma. However, it carries major trauma to the chest wall, especially in cases with chest wall involvement distant to the potential location of ‘traditional’ thoracotomies. We describe an alternative method of estimating the boundaries of chest wall resection employing video assisted thoracoscopic surgery (VATS) and hypodermic needles. METHODS VATS delineation of boundaries of chest wall involvement by lung cancer has been performed in six patients who gave written consent. In one case the single–port thoracoscopic examination revealed unexpected distant pleural metastases thus preventing from resection. The other 5 patients, three males and two females [median age of 60.5 (range 39 to 75) years] underwent en bloc anatomical lung resection in addition to chest wall excision and reconstruction for T3N0 lung cancer. RESULTS In these five cases the chest wall opening was restricted to the extent of the rib excision, and the pulmonary resection was performed via the existing chest wall opening without requiring extension of the thoracotomy or any rib spreading. DISCUSSION Minimally invasive techniques aid to delineate the boundaries of chest wall involvement of lung cancer and intraoperative staging. This helped tailoring the surgical approach and location of the thoracotomy, and prevented rib-spreading or additional thoracotomies in our cases. PMID:23592724

    Objective To compare and analyze how the 1 year disease-free survival rate of the patients with non-small cell lung cancer in stageⅠ~Ⅲafter operation is influenced by the treatment of adjuvant chemotherapy, EGFR-TKIs and only surgery retrospec-tively and to know about the clinical value of EGFR-TKIs therapy on mutated NSCLC patients. Methods 48 NSCLC patients in stageⅠ~Ⅲ who received complete resection and showed clear EGFR mutation result were divided into 4 groups: EGFR mutated patients who received postoperative adjuvant chemotherapy, EGFR mutated-negative patients who received postoperative adjuvant chemothera-py, EGFR mutated patients who took EGFR-TKIs and the patients who had only surgeries. Then, the 1 year disease-free survival rate was observed in each group respectively. Results Only stage affected 1 year disease-free survival rate. For the mutant patients, chemotherapy and EGFR-TKIs therapy showed no statistical difference in 1 year disease-free survival rate : 78. 6% ( 11/14 ) VS 75% (6/8), P=0. 620. For the patients who received adjuvant chemotherapy, mutant and mutant negative patients showed no statis-tical difference:78. 6% (11/14) VS 50% (10/20), P=0. 153, but subgroup analysis for the stage Ⅲ patients, mutant positive and negative showed difference:100% (5/5) VS 18. 2% (2/11), P=0. 005. For the stageⅠpatients, adjuvant therapy and sur-gery only group showed no difference:77. 8% (7/9) VS 100% (5/5), P=0. 505. For the stageⅠpatients taking adjuvant thera-py ( targeted therapy or chemotherapy) showed no statistical difference in 1 year disease-free survival rate. Conclusion For the pa-tients in stage Ⅰ~Ⅲwith complete resection, stage is relative to 1 year disease-free survival rate. For EGFR mutant patients, chem- otherapy and EGFR-TKIs therapy show no statistical difference in 1 year disease-free survival rate. For the mutant positive patients, adjuvant chemotherapy and targeted therapy show no statistical difference in the rate

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

    Full Text Available Lhermitte-Duclos disease (LDD is a pathologic entity with progrediating, diffuse hypertrophy chiefly of the stratum granulosum of the cerebellum. Typically LDD is a unilateral lesion of the cerebellum or in vermis. Here we report a case of LDD with bilateral lesions of cerebellar hemispheres managed surgically. A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.

    2016-01-01

    Background: Laparoscopic liver resection (LLR) has been considered to be safe and feasible.However, few studies focused on the comparison between the anatomic and nonanatomic LLR.Therefore, the purpose of this study was to compare the perioperative factors and outcomes of the anatomic and nonanatomic LLR, especially the area of liver parenchymal transection and blood loss per unit area.Methods: In this study, surgical and oncological data of patients underwent pure LLR procedures for malignant liver tumor were prospectively collected.Blood loss per unit area of liver parenchymal transection was measured and considered as an important parameter.All procedures were conducted by a single surgeon.Results: During nearly 5 years, 84 patients with malignant liver tumor received a pure LLR procedure were included.Among them, 34 patients received anatomic LLR and 50 received nonanatomic LLR, respectively.Patients of the two groups were similar in terms of demographic features and tumor characteristics, despite the tumor size was significantly larger in the anatomic LLR group than that in the nonanatomic LLR group (4.77 ± 2.57 vs.2.87 ± 2.10 cm, P =0.001).Patients who underwent anatomic resection had longer operation time (364.09 ± 131.22 vs.252.00 ± 135.21 min, P < 0.001) but less blood loss per unit area (7.85 ± 7.17 vs.14.17 ± 10.43 ml/cm2,P =0.018).Nonanatomic LLR was associated with more blood loss when the area of parenchymal transection was equal to the anatomic LLR.No mortality occurred during the hospital stay and 30 days after the operation.Moreover, there was no difference in the incidence of postoperative complications.The disease-free and overall survival rates showed no significant differences between the anatomic LLR and nonanatomic LLR groups.Conclusions: Both anatomic and nonanatomic pure LLR are safe and feasible.Measuring the area ofparenchymal transection is a simple and effective method to estimate the outcomes of the liver resection surgery

  15. Compensation following bilateral vestibular damage

    2011-12-01

    Full Text Available Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that nonlabyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained.

    Full Text Available Abstract Background Pancreatic adenocarcinoma (PCA is one of the most lethal human malignancies, and radical surgery remains the cornerstone of treatment. After resection, the overall 5-year survival rate is only 10% to 29%. At the time of presentation, however, about 40% of patients generally have distant metastases and another 40% are usually diagnosed with locally advanced cancers. The remaining 20% of patients are indicated for surgery on the basis of the results of preoperative imaging studies; however, about half of these patients are found to be unsuitable for resection during surgical exploration. In the current study, we aimed to determine the clinicopathological characteristics that predict the resectability of PCA and to conduct a prognostic analysis of PCA after resection to identify favorable survival factors. Methods We retrospectively reviewed the medical files of 688 patients (422 men and 266 women who had undergone surgery for histopathologically proven PCA in the Department of Surgery at Chang Gung Memorial Hospital in Taiwan from 1981 to 2006. We compared the clinical characteristics of patients who underwent resection and patients who did not undergo resection in order to identify the predictive factors for successful resectability of PCA, and we conducted prognostic analysis for PCA after resection. Results A carbohydrate antigen 19–9 (CA 19–9 level of 37 U/ml or greater and a tumor size of 3 cm or more independently predicted resectability of PCA. In terms of survival after resection, PCA patients with better nutritional status (measured as having an albumin level greater than 3.5 g/dl, radical resection, early tumor stage and better-differentiated tumors were associated with favorable survival. Conclusions Besides traditional imaging studies, preoperative CA 19–9 levels and tumor size can also be used to determine the resectability of PCA. Better nutritional status, curative resection, early tumor stage and well

    Lung cancer is the leading cause of cancer-related mortality worldwide. Methods for early detection of lung cancer, such as computerized tomography scanning technology, often discover a large number of small lung nodules, posing a new problem to radiologists and chest physicians. The vast majority of these nodules will be benign, but there is currently no easy way to determine which nodules represent very early lung cancer. Adjuvant testing with PET imaging and nonsurgical biopsies has a low yield for these small indeterminate nodules, carries potential morbidity and is costly. Indeed, purely morphological criteria seem to be insufficient for distinguishing lung cancer from benign nodules at early stages with sufficient confidence, therefore false positives undergoing surgical resection frequently occur. A molecular approach to the diagnosis of lung cancer through the analysis of exhaled breath could greatly improve the specificity of imaging procedures. A biomarker-driven approach to signs or symptoms possibly due to lung cancer would represent a complementary tool aimed at ruling out (with known error probability) rather than diagnosing lung cancer. Volatile and nonvolatile components of the breath are being studied as biomarkers of lung cancer. Breath testing is noninvasive and potentially inexpensive. There is promise that an accurate lung cancer breath biomarker, capable of being applied clinically, will be developed in the near future. In this article, we summarize some of the rationale for breath biomarker development, review the published literature in this field and provide thoughts regarding future directions.

    The presented data show that thyroid surgery for Graves' Disease had a high therapeutic efficiency in more than 500 own patients. Considering our actual knowledge about the pathogenesis of Graves' Disease it is obvious that inadequate results of surgery are mostly due to surgical technique, which is not radical enough. Therefore subtotal bilateral thyroidectomies leaving remnants of only 4-6 g are recommended. Even as adequate premedication has shrunk the lethality of surgery to 0--which is especially significant concerning the previously dreaded postoperative thyroid storm--complications such as vocal chord paralysis and tetany do occur in a few percent. These complications, however, can usually be controlled as well as the frequent postoperative hypothyroidism. Overall thyroid surgery for therapy of Graves' Disease seems the method of choice for the treatment of younger patients with considerable thyroid enlargement and with insufficient response to antithyroid drugs.

    “Pancoast” tumors frequently require a multidisciplinary approach to therapy and are still associated with high morbidity and mortality. Due to their sensitive anatomic location, complex resections and chemoradiation regimens are typically required for treatment. Those with signs of aortic invasion pose an even greater challenge, given the added risks of cardiopulmonary bypass for aortic resection and interposition. Placement of an aortic endograft can facilitate resection if the tumor is in close proximity to or is invading the aorta. Prophylactic endografting to prevent radiation-associated aortic rupture has also been described. This case describes a 60-year-old female who presented with a stage IIIa left upper lobe undifferentiated non-small-cell carcinoma encasing the subclavian artery with thoracic aorta and bony invasion. Following carotid-subclavian bypass with Dacron, en bloc resection of the affected lung, ribs, and vertebral bodies was performed. The aorta was prophylactically reinforced with a Gore TAG thoracic endograft prior to adjuvant chemoradiation. The patient remains disease-free at more than 5 years follow-up after completing her treatment course. Endovascular stenting with subsequent chemoradiation may prove to be a viable alternative to palliation or open operative management and prevention of aortic injury during tumor resection and/or adjuvant therapy in select patients with aortic involvement.

    Severe thoracolumbar kyphotic deformity caused by old compressive vertebrae fracture remains a big challenge for spine surgeons. When symptoms related to significant deformities cannot be adequately managed conservatively, posterior vertebral column resection (PVCR) is required, but with long operating time and severe blood loss. We develop a UPVCR technique, which is done through a unilateral approach instead of a bilateral approach, vertebral body resection advancing to cross the midline in an abrasive way from an extreme oblique orientation enable the resection of most contralateral vertebral body. In the present study, the effects of UPVCR for severe thoracolumbar kyphotic deformity were investigated. We did find that satisfactory correction of sagittal deformity, functional improvement and pain relief can be achieved by UPVCR, and it has the advantage of shortening surgery time, reducing blood loss and incidence of nerve root impingement over PVCR.

    We herein report the case of a patient with a cecal cancer with simultaneous liver, spleen, and ovarian metastases as well as peritoneal dissemination who achieved a long-term survival. The patient was a 67-year-old female. Ileocecal resection with partial hepatectomy, splenectomy, simple total hysterectomy, bilateral salpingo-oophorectomy, and resection of the peritoneal dissemination were performed. The final diagnosis was Stage IV (T4a, N1, M1b[H1, P3, OTH]). Adjuvant chemotherapy was administered, but abdominal computed tomography(CT)revealed a metachronous liver metastasis 41 months later. We performed partial hepatectomy, and the patient continued adjuvant chemotherapy. The patient is currently alive and disease-free 30 months after the last operation, 72 months after the initial surgery.

    Full Text Available Hydatid cyst is an endemic disease in our country. Most commonly, it occurs in the liver and lungs. Bilateral hydroureteronephrosis is one of the rare presentations of hydatid disease. Herein, we are reporting an unusual case of hydatid disease where the primary mode of presentation was external iliac vein compression with chronic renal failure because of bilateral ureteric involvement. The patient was treated with bilateral double-J stenting to improve the renal function and operated later for removal of hydatid cyst under albendazole drug treatment.

    Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant (both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments (1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of laparoscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.

  4. Bilateral Simultaneous Femoral Neck Fracture Mimicking Abdominal Pain in a Cerebral Palsy Patient

    2014-01-01

    Full Text Available Simultaneous bilateral femoral neck fractures are unusual lesions, generally associated with an underlying condition which causes impaired bone mineralization, triggered by an increased bone stress. We present a 24-year-old cerebral palsy patient, who was previously evaluated in another institution due to inability to walk, interpreted as abdominal pain. No alteration in blood analysis or abdominal X-rays was found. As no response to treatment was observed, a new abdominal X-ray was taken, which incidentally depicted bilateral medial femoral neck fracture. He was referred to our practice after a resection arthroplasty was offered in another institution. After admission, bilateral one-stage THA was performed. Several reports emphasize bone disease as a major precipitating factor, and there is an increased incidence of hip fractures in chronic epilepsy, renal osteodystrophy, and chronic steroid use. Femoral head resection has been proven to be effective in immobilized patients, whereas this was not a reasonable option in this patient who presented walking ability. Despite the treatment election, primary care physicians should be aware of and alert to the possibility of fractures in patients with neurological disorders and calcium metabolism alterations. Late diagnosis of orthopedic injuries in this type of patients may lead to permanent disability.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    Chondroblastoma is a benign bone tumor with a relatively high incidence in older children and adolescents. Although it is generally regarded as a benign neoplasm, it sometimes grows aggressively or recurs but rarely metastasizes to the lung. We herein present a very rare case of a bilateral pneumothorax due to a pulmonary metastasis from a chondroblastoma. A 21-year-old man developed a bilateral pneumothorax 20 months after an operation for a chondroblastoma of the right ischium. A pertinent literature review revealed similar cases of chondroblastoma with pulmonary metastasis, but revealed no reports of a pneumothorax caused by a metastatic chondroblastoma.

    Spontaneous pneumothorax (SP), as the first manifestation of lung cancer, is relatively rare, with reported occurrence rate of between 0.03% and 0.05%. The mechanism of concurrent pneumothorax with lung cancer is not clear, however several theories were proposed, including tumor necrosis mechanism and rupture of the bulla which contains tumor. We herein report two cases of lung cancer, in which the initial manifestations was only limited to SP. Without any radiologic abnormalities preoperatively, wedge resection of bullatous lung and subsequent histologic study followed. Pathologic study revealed the presence of bullatous change of the lung and combined lung cancer.

    During the last two years, reports on laparoscopic procedures of the pancreas have been on increase. Laparoscopic resection of the pancreatic cauda is indicated, primarily, for benign cystic lesions of the cauda of the pancreas and for neuroendocrine tumors of the pancreas (mainly insulinomas). We have not recorded any report on the above procedure in the Czech literature. Therefore, in our case review, we have described laparoscopic distal resection of the pancreas with splenectomy for a pseudopapillary tumor of the pancreas.

    A 35-year-old man presented with asymptomatic eruption on both forearms and lower aspects of the legs for 6 months. The lesions first appeared on his inner aspects of the wrist, the dorsal surface of the hands, and legs and progressed to involve proximal aspects of the extremities. There was no significant past history. On examination, multiple pearly white papules and depigmented atrophic plaques were found bilaterally on the flexors of the arms and the extensors of the legs. The lesions were arranged in a linear manner, following the lines of Blaschko (Figures 1 and 2). The surface of the atrophic plaques was notable for prominent telangiectasia, giving an erythematous appearance. The genitalia, oral cavity, palms, and soles were spared. Systemic examination was noncontributory. Lichen striatus and extragenital lichen sclerosus (ELS) were considered the differential diagnosis. Clinically, the age of the patient, the absence of scaling, and the presence of atrophic plaques and telangiectasia were in favor of ELS. A punch biopsy from an atrophic plaque was performed, and it revealed hyperkeratosis, atrophic epidermis, basal layer vacuolar degeneration, mild lymphocytic infiltration in the dermis, edema, and homogenization of collagen of the upper portion of the dermis (Figures 3 and Figure 4). Histopathologic findings were consistent with lichen sclerosus. A diagnosis of bilateral zosteriform ELS was made.

    Pancreatic cancer is the fourth most common cause of cancer death in the United States. Surgery remains the only curative option; however only 20% of the patients have resectable disease at the time of initialpresentation. The definition of borderline resectable pancreatic cancer is not uniform but generally denotes to regional vessel involvement that makes it unlikely to have negative surgical margins. The accurate staging of pancreatic cancer requires triple phase computed tomography or magnetic resonance imaging of the pancreas. Management of patients with borderline resectable pancreatic cancer remains unclear. The data for treatment of these patients is primarily derived from retrospective single institution experience. The prospective trials have been plagued by small numbers and poor accrual. Neoadjuvant therapy is recommended and typically consists of chemotherapy and radiation therapy. The chemotherapeutic regimens continue to evolve along with type and dose of radiation therapy. Gemcitabine or 5-fluorouracil based chemotherapeutic combinations are administered. The type and dose of radiation vary among different institutions. With neoadjuvant treatment, approximately 50% of the patients are able to undergo surgical resections with negative margins obtained in greater than 80% of the patients. Newer trials are attempting to standardize the definition of borderline resectable pancreatic cancer and treatment regimens. In this review, we outline the definition, imaging requirements and management of patients with borderline resectable pancreatic cancer.

    Primary mucoepidermoid tumors of the lung are rare entities. Synchronous primary malignancies of the lung involving mucoepidermoid carcinoma and mucinous adenocarcinoma are even rarer and constitute a unique set of patient population. The presentation, diagnosis and treatment strategies for this patient population are not well described. In most cases, the diagnosis of synchronous primary lung malignancy is made after pathological examination of the resected lung specimen. Molecular and genetic analysis is now being used to supplement the diagnosis of synchronous primary lung malignancies. In this work, we briefly discuss the current state of knowledge of this unique combination of primary lung malignancies and describe the clinical presentation and management of a patient with a rare combination of synchronous primary lung malignancies.

    Danish bilateral development assistance is aimed at reducing poverty in the partner countries. Even so, bilateral assistance may have secondary, or knock-on, effects, which are beneficial for Denmark. An important secondary effect is the prospect of increased export from Denmark to the partner...... countries. This Evaluation Study presents an econometric analysis of Danish exports to 144 countries over the period from 1981 to 2010. The analysis is based on the gravity model of bilateral trade; a structural model developed over decades and now the central model in analyses of bilateral trade flows...... and trade policies. The main result of the study is that Danish bilateral aid has a positive and statistically significant impact on Danish exports to the recipient countries. Bilateral development assistance may affect exports through several channels. Three of the main channels are direct aid tying...

    has a role only in selected cases. Our objectives are to describe clinical features, diagnostic methods and role of surgical treatment in patients with PA VM. Methods: Retrospective review of all patients with PA VM, in whom surgery was performed in our institution, from February 2005 to February 2010. The follow up controls were done through physician or telephone contact. Results: 8 patients, six females (3:1, aged between 16-68 years were analyzed. Most common sigiis and symptoms were dyspnea, cyanosis and clubbing. Right lower lobe was the most frequent location. Four had multiple PA VM and four met criteria for Rendu-Osler- Weber disease. Six patients had polycythemia and two anemia. Radiography was abnormal in all and computed tomography defined anatomy in seven. Angiography was performed in three, two had contrasted echocardiography and four had scintigraphy. Most common surgical treatment was lobectomy. Indications for surgery were the size of PA VM in five cases, failure of embolization in two and one because of intra-operative findings, without a previous diagrwsis. One had postoperative bleeding. Discharge was between day 2 and 10 days after surgery. There was no mortality. At their last control all patients were asymptomatic. Conclusion: PA VMpresents a wide and varied range of clinical and anatomical findings. They can cause major symptoms and serious complications, which justify their treatment. The preoperative study is based primarily on demonstrating the shunt and determining the anatomical characteristics of the lesion. In selected cases lung resection surgery is indicated.

    To determine if the presence of bilateral implants, in addition to other anatomic and treatment-related variables, affects coverage of the target volume and dose to the heart and lung in patients receiving postmastectomy radiation therapy (PMRT). A total of 197 consecutive women with breast cancer underwent mastectomy and immediate tissue expander (TE) placement, with or without exchange for a permanent implant (PI) before radiation therapy at our center. PMRT was delivered with 2 tangential beams + supraclavicular lymph node field (50 Gy). Patients were grouped by implant number: 51% unilateral (100) and 49% bilateral (97). The planning target volume (PTV) (defined as implant + chest wall + nodes), heart, and ipsilateral lung were contoured and the following parameters were abstracted from dose-volume histogram (DVH) data: PTV D{sub 95%} > 98%, Lung V{sub 20}Gy > 30%, and Heart V{sub 25}Gy > 5%. Univariate (UVA) and multivariate analyses (MVA) were performed to determine the association of variables with these parameters. The 2 groups were well balanced for implant type and volume, internal mammary node (IMN) treatment, and laterality. In the entire cohort, 90% had PTV D{sub 95%} > 98%, indicating excellent coverage of the chest wall. Of the patients, 27% had high lung doses (V{sub 20}Gy > 30%) and 16% had high heart doses (V{sub 25}Gy > 5%). No significant factors were associated with suboptimal PTV coverage. On MVA, IMN treatment was found to be highly associated with high lung and heart doses (both p < 0.0001), but implant number was not (p = 0.54). In patients with bilateral implants, IMN treatment was the only predictor of dose to the contralateral implant (p = 0.001). In conclusion, bilateral implants do not compromise coverage of the target volume or increase lung and heart dose in patients receiving PMRT. The most important predictor of high lung and heart doses in patients with implant-based reconstruction, whether unilateral or bilateral, is treatment of

    Cochlear implantation is a standard method of hearing rehabilitation among patients with severe to profound bilateral sensorineural hearing loss. In recent years there have been an increasing number of studies showing superior hearing with bilateral cochlear implantation in comparison with a unilateral procedure. In this study we present our experience with 15 patients, children and adults, who had bilateral cochlear implant surgery. Speech perception test results demonstrated a hearing benefit in bilateral cochlear implantation in comparison with a unilateral device, mainly by improvement in the identification of speech in noise tests.

    We report a rare case of extravasation of urine, which may be associated with bilateral complete ureteral duplication, vesicoureteral reflux (VUR), and benign prostatic hyperplasia (BPH). A 71-year-old male presented with a complaint of right abdominal pain. An extravasation of urine was noted, and was improved by indwelling urethral catheterization. Transurethral resection of the prostate and the endoscopic subureteral injection of dextanomer/hyaluronic acid were performed for the treatment of BPH and VUR, respectively. The post-surgery recovery was successful.

    Full Text Available Bilateral cryptorchidism is a rare occurrence and seminoma is the most common germ cell tumor found in undescended testes when they occur. We present the case of a patient with bilateral cryptorchidism who presented to our trauma center after a motor vehicle collision and was found incidentally to have a 17-cm intra-abdominal mass. The mass was subsequently biopsied and proven to be seminoma. The patient completed three cycles of bleomycin/etoposide/cisplatin chemotherapy and successfully underwent a postchemo retroperitoneal lymph node dissection with no viable residual tumor or positive lymph nodes found in the surgical specimen. He also had an orchiopexy of the contralateral testicle. The patient recovered fully and has been found to be recurrence-free four months postoperatively. We highlight the importance of cisplatin-based chemotherapy and extensive tumor resection as the mainstay of initial cancer control.

    Cushing's syndrome due to ectopic adrenocorticotrophic hormone (ACTH) secretion is infrequent, the most frequent cause being bronchial carcinoid; nevertheless, in a considerable proportion of cases (up to 16%), the origin of ACTH secretion is not found. Treatment of Cushing's syndrome due to ectopic ACTH secretion is surgical resection of the tumor. However, surgical excision is not always feasible, either because the tumor has not been located, or because it is unresectable; in these cases the question is when to carry out a bilateral adrenalectomy. We present a case of ACTH-dependent hypercortisolism, in which the ectopic origin of ACTH secretion was established from the results of complementary tests (suppression tests, petrosal sinus sampling, imaging); nevertheless, none of the imaging tests was able to identify the secreting tumor. Consequently, after a reasonable interval, a bilateral adrenalectomy was performed, with good clinical results.

  9. Transient Occlusion of Bilateral Internal Iliac Arteries Facilitates Bloodless Operative Field in Subcapsular Prostatectomy

    2012-01-01

    Full Text Available Transurethral resection of the prostate is the gold standard of surgical treatment for benign prostatic hyperplasia (BPH. Nevertheless, open subcapsular prostatectomy is still performed for large BPH. While enucleation of prostatic adenoma is being performed, unneglectable bleeding can occur and surgeons need to rush to remove adenomas, often using fingers and in a blinded fashion. The blood supply to the prostatic capsule and adenoma can be reduced to a marked extent in subcapsular prostatectomy if the bilateral internal iliac arteries are transiently occluded. Thus, a bloodless operative field is reasonably acquired during enucleation of adenoma, which would, otherwise, be a cause for concern to surgeons due to bleeding. It is not always applicable, but it could be an option if the estimated volume of BPH is more than 100 mL. In two cases, bilateral internal iliac arteries were occluded with Bulldog clamps, and then adenomas of 159 and 97 g were enucleated.

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

    A lung cancer diagnosis and associated therapeutic management is associated with unique and varying degrees of adverse physical/functional impairments that dramatically reduce a patient's ability to tolerate exercise. Poor exercise tolerance predisposes to increased susceptibility to other common age-related diseases, poor quality of life (QOL), and likely premature death. Here we review the putative literature investigating the role of exercise as an adjunct therapy across the lung cancer continuum (i.e., diagnosis to palliation). The current evidence suggests that exercise training is a safe and feasible adjunct therapy for operable lung cancer patients both before and after pulmonary resection. Among patients with inoperable disease, feasibility and safety studies of carefully prescribed exercise training are warranted. Preliminary evidence in this area supports that exercise therapy may be an important consideration in multidisciplinary management of patients diagnosed with lung cancer.

    Abstract This study aimed to determine the prognostic effects of preoperative chemotherapy for colorectal cancer liver metastasis (CLM). We retrospectively evaluated 2 groups of patients between January 2006 and August 2012. A total of 53 patients who had ≥3 hepatic metastases underwent resection after preoperative chemotherapy (preoperative chemotherapy group), whereas 96 patients who had ≥3 hepatic metastases underwent resection with a curative intent before chemotherapy for CLM (primary resection group). A propensity score (PS) model was used to compare the both groups. The 3-year disease-free survival (DFS) rates were 31.7% and 20.4% in the preoperative chemotherapy and primary resection groups, respectively (log-rank = 0.015). Analyzing 32 PS matched pairs, we found that the DFS rate was significantly higher in the preoperative chemotherapy group than in the primary resection group (3-year DFS rates were 34.2% and 16.8%, respectively [log-rank = 0.019]). Preoperative chemotherapy group patients had better DFSs than primary resection group patients in various multivariate analyses, including crude, multivariable, average treatment effect with inverse probability of treatment weighting model and PS matching. Responses to chemotherapy are as important as achieving complete resection in cases of multiple hepatic metastases. Preoperative chemotherapy may therefore be preferentially considered for patients who experience difficulty undergoing complete resection for multiple hepatic metastases. PMID:28207557

    Full Text Available Granulomatosis with polyangiitis is autoimmune and rare disease. It affects many organs, but the most often affected organs are the nose, lungs, and kidneys. It is part of vasculitis and causes an autoimmune attack by an abnormal type of circulating antibody termed ANCAs against small blood vessels. Disease concerns both men and women with a peak age of presentation in the sixth and seven decades. Typically upper and lower respiratory tract and kidneys are involved. Otitis externa, otitis media, or mastoiditis rarely occurs in granulomatosis with polyangiitis. Deafness is the most dangerous aural complication. Histological examination of biopsy is often not specific. A case of GPA with bilateral otitis media, bilateral deafness, and bilateral facial palsy with fatal course is presented.

    Of 312 patients undergoing resection for lung cancer at National Taiwan University Hospital during 1980 to 1990, eight presented with second primary lung cancer. One patient had synchronous and seven patients had metachronous primaries. There were five males and three females with ages ranging from 41 to 77 years. In the metachronous group, two patients had a different histology between the first and the second tumor, and the intervals between the two tumors varied from 12 to 60 months. The initial resections included pneumonectomy in one and lobectomy in six patients. At the second operation, the surgical procedures included lobectomy in three, completed pneumonectomy in one, segmentectomy in another, and wedge resection in two patients. There was no operative mortality and all patients were regularly followed up from 6 months to 6 years after the second operation. Two patients died, one from repeated respiratory tract infection and the other from brain metastasis. Kaplan-Meier analysis showed 2-year and 3-year survivals of 80% and 60%, respectively. It can be concluded that surgical resection for second primary lung cancer is justified, as it can prolong the patient's survival. Lobectomy can be performed for patients with a second primary lung cancer and sufficient lung reserve, but limited resection should be chosen for patients with poor lung reserve.

    Full Text Available Abstract Background Surgery is often advocated in patients with resectable pulmonary metastases from colorectal cancer (CRC. Our study aims to evaluate peri-operative chemotherapy in patients with metastastic CRC undergoing pulmonary metastasectomy. Methods Patients treated for CRC who underwent pulmonary metastasectomy by a single surgeon were identified. Outcome measures included survival, peri-operative complications, radiological and histological evidence of chemotherapy-induced lung toxicities. Results Between 1997 and 2009, 51 eligible patients were identified undergoing a total of 72 pulmonary resections. Thirty-eight patients received peri-operative chemotherapy, of whom 9 received an additional biological agent. Five-year overall survival rate was 72% in the whole cohort - 74% and 68% in those who received peri-operative chemotherapy (CS and those who underwent surgery alone (S respectively. Five-year relapse free survival rate was 31% in the whole cohort - 38% and ≤18% in CS and S groups respectively. Only 8% had disease progression during neoadjuvant chemotherapy. There were no post-operative deaths. Surgical complications occurred in only 4% of patients who received pre-operative chemotherapy. There was neither radiological nor histological evidence of lung toxicity in resected surgical specimens. Conclusions Peri-operative chemotherapy can be safely delivered to CRC patients undergoing pulmonary metastasectomy. Survival in this selected group of patients was favourable.

    Fibular osteoseptocutaneous flap has been widely used for unilateral mandibular reconstruction. However, reports about the effects of fibular osteoseptocutaneous flap for the reconstruction of bilateral mandibular defects are limited. In this study, we used free vascularized fibular flaps to successfully manage bilateral mandibular osteoradionecrosis(ORN) in 5 patients. Functional aspects were evaluated during the reconstruction process. All 5 patients had bilateral refractory ORN of the mandible and underwent radical resection between 2003 and 2011. The reconstruction surgery was performed in 2 stages using 2 free fibular flaps in 3 patients. In the other 2 patients, reconstruction was performed in a single stage using 2 separate flaps prepared from a single fibula. All patients had a healthy mandibular symphysis and meniscus of the temporomandibular joint, and these structures were preserved during the reconstruction.Of the 10 defects involving the mandible sides, 9 were successfully reconstructed. One microvascular composite flap failed because of radiation injury to the arterial endothelium at the recipient site. After the treatments, all patients had good esthetic and functional outcomes. Preoperative clinical features such as trismus and dysphagia were also markedly improved. Our surgical method may be an effective alternative for the clinical management of advanced bilateral mandibular ORN.

In this retrospective study, indications for liver resection were malignant tumors in 17 (Elective cases and 6 patients with trauma etiology (Emergency cases. Results. Left lateral segmentectomy (segments II-III was done in 9 patients. Segment VI resection was performed in 4 patients. Non-anatomical (wedge resections were done in 10 patients. The average time necessary for transection of the liver parenchyma was 34±5 min. in Elective group and 37±5min. in Emergency group. Average blood loss was 32±5 mL in Elective group and 89±8 mL in Emergency group. In the postoperative period, we did not see any subcapsular or perihepatic hematoma responsible for delayed hemorrhage. No signs of infectious disease or abscesses were observed. Conclusion. This RF assisted technique is effective in bloodless liver resections.

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    Postoperative bilateral adrenal hemorrhage is a rare but potentially life-threatening complication. This diagnosis is often missed because the symptoms and laboratory results are usually nonspecific. We report a case of bilateral adrenal hemorrhage associated with acute primary adrenal insufficiency following laparoscopic cholecystectomy. The knowledge of this uncommon complication following any abdominal surgery allows timey diagnosis and rapid treatment.

    Full Text Available Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Limited data available for bilateral PDA stenting. Bilateral PDA stenting in nonconfluent pulmonary arteries is challenging procedure but can be considered as an option in the management of complex conditions like this. 12 days old Preterm (36 weeks gestation male baby with birth weight of 2.6 kg developed respiratory distress with severe cyanosis and desaturation upto 50%. Baby was intubated and started on Prostaglandin 0.05 mic/kg/mt. His saturation improved to 80%. Echocardiogram showed complex cyanotic heart disease, Situs ambiguous, dextrocardia, complete unbalanced AV septal defect, pulmonary atresia , nonconfluent small branch pulmonary arteries supplied by the bilateral patent ductus arteriosus (PDA from right aortic arch and all four pulmonary veins form a confluence and drain into superior vena cava(SVC through vertical vein with no obstruction. Baby was taken up for PDA stenting. descending aortogram showed right aortic arch with vertical tortuous duct to right pulmonary artery (RPA and another short duct with acute angle from left subclavian artery to left pulmonary artery (LPA . Both ducti stented with coronary stents. Vertical vein angiogram showed both lungs drain to a confluence and then to SVC via ascending vertical vein with no obstruction. After stenting lung perfusion improved and the baby was stable and maintained 80% saturation on room air. Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Our case is unique with Heterotaxy, TAPVC, Dextrocardia and double ducti. Eventhough bilateral ductal stenting is technically challenging it is successful through femoral artery approach.

    We introduce a new type of multiple zeta functions, which we call bilateral zeta functions, analogous to the Barnes zeta functions. The bilateral zeta function is a periodic function and shares certain basic properties of Barnes zeta function. Especially, we prove that the bilateral zeta function has a nice Fourier series expansion and the Barnes zeta function can be expressed as a finite sum of bilateral zeta functions. By these properties of the bilateral zeta functions, We obtain simple proofs of some formulas, for example the reflection formula for the multiple gamma function, the inversion formula of the Dedekind eta function, Ramanujan's formula, Fourier expansion of the Barnes zeta function and multiple Iseki's formula.

    ABSTRACT Lung transplantation is a globally accepted treatment for some advanced lung diseases, giving the recipients longer survival and better quality of life. Since the first transplant successfully performed in 1983, more than 40 thousand transplants have been performed worldwide. Of these, about seven hundred were in Brazil. However, survival of the transplant is less than desired, with a high mortality rate related to primary graft dysfunction, infection, and chronic graft dysfunction, particularly in the form of bronchiolitis obliterans syndrome. New technologies have been developed to improve the various stages of lung transplant. To increase the supply of lungs, ex vivo lung reconditioning has been used in some countries, including Brazil. For advanced life support in the perioperative period, extracorporeal membrane oxygenation and hemodynamic support equipment have been used as a bridge to transplant in critically ill patients on the waiting list, and to keep patients alive until resolution of the primary dysfunction after graft transplant. There are patients requiring lung transplant in Brazil who do not even come to the point of being referred to a transplant center because there are only seven such centers active in the country. It is urgent to create new centers capable of performing lung transplantation to provide patients with some advanced forms of lung disease a chance to live longer and with better quality of life.

    DNA double-strand breaks (DSBs), which arise following exposure to a number of endogenous and exogenous agents, can be repaired by either the homologous recombination (HR) or non-homologous end-joining (NHEJ) pathways in eukaryotic cells. A vital step in HR repair is DNA end resection, which generates a long 30 single-stranded DNA (ssDNA) tail that can invade the homologous DNA strand. The generation of 30 ssDNA is not only essential for HR repair, but also promotes activation of the ataxia telangiectasia and Rad3-related protein (ATR). Multiple fac-tors, including the MRN/X complex, C-terminal-binding protein interacting protein (CtIP)/Sae2, exonuclease 1 (EXO1), Bloom syndrome protein (BLM)/Sgs1, DNA2 nuclease/helicase, and several chromatin remodelers, cooperate to complete the process of end resection. Here we review the basic machinery involved in DNA end resection in eukaryotic cells.

    2001-01-01

    Objective: To investigate the expression of novel multidrugresistance transporter (BCRP gene) from human MCF-7/AdrVp breast cancer cells in normal lung tissue and non-small lung cancer tissue. Methods: RNA was extracted immediately from fresh normal lung tissue and viable tumor tissue harvested from surgically resected specimens of non-small cell lung cancer patients. cDNA of BCRP gene was prepared by RT-PCR and was then amplified by PCR. cDNA products from those specimens were transferred to blotting membrane through electrophoresis and transferring technique and southern blot hybridization was eventually performed to detect the expression of BCRP gene. Results: RNA were extracted from 8 tumor tissue alone and 12 pairs of tumor tissue and normal lung tissue harvested from the same lung. Four patients' RNA samples with poor quality due to degrading were discarded. cDNA products of BCRP gene were obtained by RT-PCR and were then amplified by PCR in the remain 16 patients' RNA samples. Through southern blot hybridization, BCRP gene was found to be slightly expressed in various amounts in all normal lung tissue (10/10) and only in a half of tumor tissue samples (8/16). Conclusion: BCRP gene is slightly expressed in different amount in all normal lung tissue and only in a half of tumor tissue of non-small cell lung cancer patients. It is possible to induce it's overexpression and to develop multidrug resistance during chemotherapy if using anthracycline anticancer drugs.

    Objective: To investigate and evaluate improvement of lung cancer survival after surgical intervention in PUMC hospital during the last 15 years. Methods: From January 1989 to December 2003, 1574 lung cancer cases underwent surgical treatment and followed up. All cases in this series were divided into two groups according to time period: group A (1999-2003) and group B (1989-1998). The difference in the survival rate between groups A and B was compared. Results: The morbidity and mortality in group A was decreased significantly in comparison to group B (11.2% vs. 19.2%, 1.06% vs. 1.93%, respectively).However, the 3-year and 5-year survival rate was increased from 42.35% to 56.07%, and from 28.46% to38.99%, respectively. A significant improvement in survival was observed in patients with stage Ⅰ, Ⅱ and ⅢA, but not in those with stage ⅢB and Ⅳ. Also, patients with lobectomy had more satisfactory results than those receiving exploratory thoracotomy, limited resection, pneumonectomy and sleeve resection. Conclusion: Lobectomy plus systematic mediastinal lymph nodes dissection has become the standard mode for resectable lung cancer. Combination of complete resection along with lymph nodal dissection, and postoperative adjuvant chemotherapy based on platinum/3rd generation chemotherapy medicine, has preliminarily been justified, proving an important approach for effective improvement in long-term survival of non-small cell lung carcinoma.

    2014-02-01

    Open resection arthroplasty of the sternoclavicular (SC) joint has historically provided good long-term results in patients with symptomatic osteoarthritis of the SC joint. However, the procedure is rarely performed because of the risk of injury to vital mediastinal structures and concern regarding postoperative joint instability. Arthroscopic decompression of the SC joint has therefore emerged as a potential treatment option because of many recognized advantages including minimal tissue dissection, maintenance of joint stability, avoidance of posterior SC joint dissection, expeditious recovery, and improved cosmesis. There are, however, safety concerns given the proximity of neurovascular structures. In this article we demonstrate a technique for arthroscopic SC joint resection arthroplasty in a 26-year-old active man with bilateral, painful, idiopathic degenerative SC joint osteoarthritis. This case also highlights the pearls and pitfalls of arthroscopic resection arthroplasty for the SC joint. There were no perioperative complications. Four months postoperatively, the patient had returned to full activities, including weightlifting, without pain or evidence of SC joint instability. One year postoperatively, the patient showed substantial improvements in the American Shoulder and Elbow Surgeons score; Single Assessment Numeric Evaluation score; Quick Disabilities of the Arm, Shoulder and Hand score; and Short Form 12 Physical Component Summary score over preoperative baseline values.

    Urinary function was evaluated after personal interview in 34 patients and after examination of the results of a urodynamic study in 15 of these, in whom resection for carcinoma of the rectum with preoperative irradiation therapy was performed. From the results of the personal interview, urinary urgency was found to have occurred in 19.2% when preoperative radiation was over. Urinary function after surgery was preserved in the group of patients who had undergone bilateral and unilateral pelvic plexus nerve preserving operations, whereas urinary dysfunction occurred in 66.7% of the group of patients who had undergone operations without pelvic plexus nerve preservation. Urinary dysfunction was recognized in 53.9% of the group of patients who had undergone abdominoperineal resection, but in none of the group of patients who had undergone low anterior resection. The urodynamic study showed that 21.4% had residual urinary output of more than 40 ml, 23.1% had the first desire to void at less than 100 ml, 15.4% had the maximum desire to void at less than 200 ml, 28.6% had compliance of the bladder at less than 20 ml/cmH[sub 2]O when preoperative irradiation was over, and these data became worse 1 month after surgery. However, these phenomena were improved 1 year after surgery. (author).

    2012-01-01

    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.

    2006-01-01

    BACKGROUND: Nasopharyngeal carcinoma (NPC) has a propensity to develop distant metastases at a high rate and with poor prognosis. Metastatic sites are usually multifocal and involve bones, lungs, liver and distant lymph nodes. Management of metastatic disease is essentially palliative and is based on chemotherapy. METHODS:A 50-year-old man with a solitary liver metastasis from a newly diagnosed NPC was treated by segmentectomy. Prior to surgery, neoadjuvant chemo-therapy followed by concurrent chemoradiotherapy was administered. RESULTS:Complete remission of the primary disease was achieved, although the size of the hepatic lesion was increased. After resection of the liver metastasis, no signs of local or distant recurrence was noted during the 6-month follow up. CONCLUSION:Although surgical treatment has a limited role in metastatic NPC, there are rare cases of localized disease with a reasonable outcome after resection.

    AIM: To evaluate survival in patients undergoing palliative resection versus non-resection surgery for primary colorectal cancer in a retrospective analysis.METHODS: Demographics, TNM status, operating details and survival were reviewed for 67 patients undergoing surgery for incurable colorectal cancer. Palliative resection of the primary tumor was performed in 46 cases in contrast to 21 patients with non-resection of the primary tumor and bypass surgery. Risk factors for postoperative mortality and poor survival were analyzed with univariate and multivariate analyses.RESULTS: The two groups were comparable in terms of age, gender, preoperative presence of ileus and tumor stage. Multivariate analysis showed that median survival was significantly higher in patients with palliative resection surgery (544 vs 233 d). Differentiation of the tumor and tumor size were additional independent factors that were associated with a significantly poorer survival rate.CONCLUSION: Palliative resection surgery for primary colorectal cancer is associated with a higher median survival rate. Also, the presence of liver metastasis and tumor size are associated with poor survival. Therefore,resection of the primary tumor should be considered in patients with non-curable colon cancer.

    Lung cancer is a leading cause of death in the civilised world. Surgical resection, which play a crucial role in the complex oncological treatment, has to be offered in older ages than it was done before, due to an ageing population. Results of surgical treatment of patients older than 75 years are investigated retrospectively in the present paper. A retrospectively analysis was carried out of 54 from a total of 884 lung resections for primary lung cancer performed for patients older than 75 years between 1995-2005. Twelve of these patients were above 80 years. Kaplan-Meier analysis was performed to calculate survival and multifactor analysis for the risk factors. Average age was 77.5 years (75-85). Two pneumonectomies, two bilobectomies, 41 lobectomies, seven sublobar resections and two lobectomies with chest wall resections were performed. The average hospital stay was 11.4 days (8-36). Mortality: 7.4% (n = 4), morbidity: 52% (n = 28) including: sputum retention: 43%, arrhythmia 33%, atelectasia: 15%. There were two bronchial stump insufficiencies (4%) and three reoperations were performed (5%). The average follow up was: 32 months and the five year survival 33.7% (median 43 months). Multifactorial analysis show that extended resection, male gender, age above 80 years are risk factors for adverse outcome. Female gender, stage Ia and lobectomy are considered as predictive factors for long survival. We conclude, that with proper patient selection (below ASA3, early stage) and with carefully conducted postoperative care (physiotherapy, monitoring) surgical resection should be offered to elderly lung cancer patients as well.

    Full Text Available Belatacept is a novel immunosuppressant that blocks a T-cell costimulation pathway and is approved for use in adult kidney transplant recipients. Its safety and efficacy have not been established after lung transplantation. We present a case of a lung transplant recipient treated with belatacept. A 56-year-old man underwent bilateral lung retransplantation for bronchiolitis obliterans syndrome (BOS. In the third year posttransplant, he developed hemolytic uremic syndrome (HUS attributed to tacrolimus. Tacrolimus was changed to sirolimus. One month later, he presented with worsening renal function and HUS attributed to sirolimus. Plasmapheresis and steroid pulse were initiated with clinical improvement, and sirolimus was switched to belatacept. He experienced no episodes of cellular rejection but developed recurrent BOS. Complications during treatment included anemia and recurrent pneumonias. The safety and efficacy of belatacept in lung transplantation remains unclear; further studies are needed.

    Combined pulmonary fibrosis and emphysema (CPFE) is defined as upper lobe emphysema and lower lobe fibrosis, which are representative lung disorders that increase the prevalence of lung cancer. This unique disorder may affect the morbidity and mortality during the early period after surgery. The present study aimed to identify which clinicopathological features significantly affect early surgical outcomes after lung resection in nonsmall cell lung cancer (NSCLC) patients and in those with CPFE.We retrospectively assessed 2295 patients with NSCLC and found that 151 (6.6%) had CPFE. All were surgically treated between January 2008 and December 2010 at 4 institutions.The postoperative complication rates for patients with and without CPFE were 39% and 17%, respectively. The 90-day mortality rates were higher among patients with than without CPFE (7.9% vs 1%). Acute exacerbation of interstitial pneumonia was the main cause of death among 12 patients with CPFE who died within 90 days after surgery. Multivariate logistic regression analysis selected CPFE, gender, age, and clinical stage as independent predictive factors for postoperative complications, and CPFE, clinical stage, and sex for 90-day mortality. The severity of lung fibrosis on preoperative CT images was an independent predictive factor for 90-day mortality among patients with CPFE.The key predictive factor for postoperative mortality and complications of lung resection for NSCLC was CPFE. The severity of lung fibrosis was the principal predictor of early outcomes after lung surgery among patients with CPFE and NSCLC.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had som-nolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous flu-conazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    A 51-year-old female patient, who had undergone left-sided modified radical mastectomy for left breast carcinoma 4 years ago, presented with dyspnea of 4 months duration F-18 FDG PET/CT of this patient showed diffusely in-creased FDG uptake in the bilateral lung fields along the thickened bronchovascular bundles. SUVmax of lymphangitic lung was 5.2. The standardized uptake ratio (SUR) of mediastinal blood pool to lymphangitic lung was 0.44. High resolution computed tomography (HRCT) of the same patient showed thickening of interlobular septa and bronchovaseular bundles, with preservation of normal parenchymal architecture. Multiple intrapulmonary nodules and bilateral hilar lymphadenopathy with pulmonary lymphangitic carcinomatosis (PLC). The lungs are the second most common sites for metastases after lymph nodes. These metastases are usually nodular on radiologic images. PLC with interstitial involvement constitutes only 7% of pulmonary metastastases. The most common primary sites, in order of frequency, are adenocarcinoma of the lung, breast, stomach, colon, and prostrate. HRCT has been the modality of choice in the radiologic diagnosis of PLC. Only a few studies have de-scribed the F-18 FDG PET/CT findings in pulmonary lymphangitic carcinomatosis. These studies have shown diffusely increased FDG uptake corresponding to the typical changes in the CT as the most common finding. One study has reported that F-18 FDG PET/CT is 100% specific and 86% sensitive in diagnosing PLC by subjective analysis. The mean SUV in the region of pulmonary lymphangitic lung was 1.26{+-}0.45 and that of blood pool to normal lung was 3.78{+-}1.37.

    @@ Pulmonary chondroma is a rare form of benign neoplasms of the lung, of which the cartilage is the only constituent. Most of the patients with lung chondroma are asymptomatic at the time of diagnosis and the occupying lesion in lung is mostly detected in the routine health examination. The image of pulmonary chondroma is similar to the other benign solitary neoplasms of the lung and the definitive diagnosis can only be established under a microscope after the resection of the tumor. In the present report, a 33-years-old woman with chondroma in the left lower lung was described.

    Purpose The aim of this study was to verify that laparoscopic resection for treating retroperitoneal benign neurilemmoma (NL) is expected to be favorable for complete resection of tumor with technical feasibility and safety. Methods We retrospectively analyzed 47 operations for retroperitoneal neurogenic tumor at Yonsei University College of Medicine, Severance Hospital and Gangnam Severance Hospital between January 2005 and September 2015. After excluding 21 patients, the remaining 26 were divided into 2 groups: those who underwent open surgery (OS) and those who underwent laparoscopic surgery (LS). We compared clinicopathological features between the 2 groups. Results There was no significant difference in operation time, estimated blood loss, transfusion, complication, recurrence, or follow-up period between 2 groups. Postoperative hospital stay was significantly shorter in the LS group versus the OS group (OS vs. LS, 7.00 ± 3.43 days vs. 4.50 ± 2.16 days; P = 0.031). Conclusion We suggest that laparoscopic resection of retroperitoneal benign NL is feasible and safe by obtaining complete resection of the tumor. LS for treating retroperitoneal benign NL could be useful with appropriate laparoscopic technique and proper patient selection.

    Parabolic resection, named for the shape of the cut edges of the excised tissue, expands on a common 'trick' used by experienced mitral surgeons to preserve tissue and increase the probability of successful repair. Our objective was to describe and clinically analyze this simple modification of conventional resection. Thirty-six patients with mitral regurgitation underwent valve repair using parabolic resection in combination with other techniques. Institution specific mitral data, Society of Thoracic Surgeons data and preoperative, post-cardiopulmonary bypass (PCPB) and postoperative echocardiography data were collected and analyzed. Preoperative echocardiography demonstrated mitral regurgitation ranging from moderate to severe. PCPB transesophageal echocardiography demonstrated no regurgitation or mild regurgitation in all patients. Thirty-day surgical mortality was 2.8%. Serial echocardiograms demonstrated excellent repair stability. One patient (2.9%) with rheumatic disease progressed to moderate regurgitation 33 months following surgery. Echocardiography on all others demonstrated no or mild regurgitation at a mean follow-up of 22.8+/-12.8 months. No patient required mitral reintervention. Longitudinal analysis demonstrated 80% freedom from cardiac death, reintervention and greater than moderate regurgitation at four years following repair. Parabolic resection is a simple technique that can be very useful during complex mitral reconstruction. Early and intermediate echocardiographic studies demonstrate excellent results.

    AIM: To summarize the clinical experience of laparoscopic hepatectomy at a single center.METHODS: Between November 2003 and March 2009, 78 patients with hepatocellular carcinoma ( n = 39), metastatic liver carcinoma ( n = 10), and benign liver neoplasms ( n = 29) underwent laparoscopic hepatectomy in our unit. A retrospective analysis was done on the clinical outcomes of the 78 patients.RESULTS: The lesions were located in segments Ⅰ ( n = 3), Ⅱ ( n = 16), Ⅲ ( n = 24), Ⅳ ( n = 11), Ⅴ ( n = 11),Ⅵ ( n = 9), and Ⅷ ( n = 4). The lesion sizes ranged from 0.8 to 15 cm. The number of lesions was three ( n = 4),two ( n = 8) and one ( n = 66) in the study cohort. The surgical procedures included left hemi-hepatectomy ( n = 7), left lateral lobectomy ( n = 14), segmentectomy ( n = 11), local resection ( n = 39), and resection of metastatic liver lesions during laparoscopic surgery for rectal cancer ( n = 7). Laparoscopic liver resection was successful in all patients, with no conversion to open procedures. Only four patients received blood transfusion (400-800 mL). There were no perioperative complications, such as bleeding and biliary leakage. The liver function of all patients recovered within 1 wk, and no liver failure occurred.CONCLUSION: Laparoscopic hepatectomy is a safe and feasible operation with minimal surgical trauma. It should be performed by a surgeon with sufficient experience in open hepatic resection and who is proficient in laparoscopy.

    Full Text Available Background: A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described. Materials and Methods: Eleven patients (seven men and four women with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis. Results: Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum. There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years. The average operating time was 130 min (range 90-210 min. The average incision length was 3.2 cm (2.5-4.0 cm. There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days. Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes. Conclusion: Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

    Acoustic neuroma surgery is a procedure in which a benign mass is removed from the Internal Auditory Canal (IAC). Currently this surgical procedure requires manual drilling of the temporal bone followed by exposure and removal of the acoustic neuroma. This procedure is physically and mentally taxing to the surgeon. Our group is working to develop an Acoustic Neuroma Surgery Robot (ANSR) to perform the initial drilling procedure. Planning the ANSR's drilling region using pre-operative CT requires expertise and around 35 minutes' time. We propose an approach for automatically producing a resection plan for the ANSR that would avoid damage to sensitive ear structures and require minimal editing by the surgeon. We first compute an atlas-based segmentation of the mastoid section of the temporal bone, refine it based on the position of anatomical landmarks, and apply a safety margin to the result to produce the automatic resection plan. In experiments with CTs from 9 subjects, our automated process resulted in a resection plan that was verified to be safe in every case. Approximately 2 minutes were required in each case for the surgeon to verify and edit the plan to permit functional access to the IAC. We measured a mean Dice coefficient of 0.99 and surface error of 0.08 mm between the final and automatically proposed plans. These preliminary results indicate that our approach is a viable method for resection planning for the ANSR and drastically reduces the surgeon's planning effort.

  8. Proximal Gastrojejunal Reconstruction after Pancreaticoduodenal Resection

    Directory of Open Access Journals (Sweden)

    M. Wayne

    2012-01-01

    Full Text Available Introduction. Reconstruction by proximal gastrojejunostomy, and distal biliary and pancreatic anastomoses is infrequently used after resection of the head of the pancreas because of fear of fistulas and cholangitis. Pancreaticoduodenectomy is being performed more frequently for cystic malignant and premalignant lesions. Because of this there is a need for endoscopic visualization and biopsy of the residual pancreatic duct, since multi-centricity is characteristic of some of these malignancies. Since endoscopic access of the bile duct and pancreatic duct is difficult and unsuccessful in 50–70% after B II or Roux Y reconstruction, we prospectively studied the merit and complications (early and late of proximal gastrojejunal (PGJ reconstruction after pancreaticoduodenal resection. Material and Methods. Thirty nine consecutive, non-radomized patients underwent pancreaticoduodenectomy and PGJ reconstruction over 14 mos. There were 21 males and 18 females. Results. 7 patients with IPMN have undergone repeat CT scanning for surveillance, with 3 requiring repeat EUS and ERCP. There were no technical difficulties accessing the pancreas or the pancreatic duct, supporting the PGJ reconstruction. Conclusion. Proximal gastrojejunal reconstruction following pancreaticoduodenal resection may be safely done with similar morbidity to traditional pancreaticojejunal reconstructions. PGJ reconstruction may be of greater value when direct visual access to the bile duct or pancreatic duct is necessary, and should be considered when doing resection for mucinous cysts or IPMN of the head of the pancreas.

    Full Text Available Introduction Multiorgan resection for a malignancy is a very comlicated procedure, but there is always the question: does it work? In everyday clinical practice gastric cancer in phases III and IV is rather frequent. Unfortunately, our patients are under the age of 55 years. D2 lymphadenectomy is not as extensive as D2 %/ or D3, so one must ask himself if multiorgan resection is worth the risk. Material and methods We evaluated two groups of patients: group I consisted of 34 patients who underwent total or subtotal gastrectomy, systematic lymphadenectomy and resection of one or more organs; group II (control consisted of 167 patients who underwent total or subtotal gastrectomy and systematic lymphadenectomy. These two groups of patients were analzyed in regard to: Bormann's classification, histopathologic type, early mortality, early postoperative complications, lymph node dissection and long-term survival. Results According to Bormann's classification the most common type of carcinoma in both groups was ulcerovegetativ tumor (70.6% in I and 58% in II. In the first group of patients a great number of patients had poorly differentiated adenocarcinomas (47%, while in the second group the most common histologic type was well differentiated intestinal carcinoma (28%. Patients with multiorgan resections had higher rates of early postoperative mortality and morbiditiy (mortality - 14.7% and complications - 26.5% than patients in control group (mortality - 4.8% and complications - 11.4%. The most frequent causes of postopertive mortality and morbidity were anastomotic leakage and wound infections in both groups. Metastatic lymph node invelvement was higher in the first group (41%, than in the second (28%. Long-term survival was best in the control group (38.5 months. Patients with multiorgan resection had better survival (25.4 months than inoperable cases (only 5 months. Discussion Patients undergoing multiorgan resection usually have advanced gastric

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    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.)

    2015-01-01

    Patients with recurrences from pancreas adenocarcinoma have a poor survival rate despite new chemotherapy treatment options. Recurrences are mainly hepatic metastases or peritoneal dissemination and surgical treatment is not recommended. Late and single metachronous pulmonary recurrences are uncommon and may mimic primary lung carcinoma. We report two patients with late and unique pulmonary metastasis from pancreatic cancer. These two patients underwent surgical resection; three and five years later, they did not experience recurrences. Cases called for a surgical approach in late and unique pulmonary metastases from pancreatic cancer, and paved the way for a prolonged chemotherapy free period.

    From June 1986 to December 1992, 16 patients (12 men and 4 women, 63 years-old [36 to 79]) who underwent a prior sphincter-saving resection for colorectal adenocarcinoma were operated on for locoregional recurrence with a surgical resection. Eight patients had a second anterior resection (5 colorectal, 2 coloanal and 1 ileoanal anastomosis), one a resection without anastomosis, and 7 an abdomino-perineal resection. Nine patients received an intraoperative irradiation (10 to 25 Gy). Excisions of surrounding organs were often necessary. Post-operative complications occurred in most of the patients. Excluding 3 post-operative deaths, 9 patients died of disease in a median of 12.9 months after surgery (range: 3 to 32 months). Four patients are still living 5 to 14 months after the second resection. There is little in the surgical literature dealing with these difficult surgical problem of which results are always uncertain. An earlier diagnosis of the recurrence would result in a more satisfactory procedure, but is difficult because of the limited possibilities of detection after surgical treatment and often external irradiation.

    BACKGROUND: Liver resection is currently the most efficient curative approach for a wide variety of liver tumors. The ap-plication of modern techniques and new surgical devices has improved operative outcomes. Radiofrequency ablation is used more often for liver parenchymal transection. This study aimed to assess the efficacy and safety of radiofrequency abla-tion-assisted liver resection. METHODS: A retrospective study of 145 consecutive patients who underwent radiofrequency ablation-assisted liver resec-tion was performed. Intraoperative blood loss, need for trans-fusion or intraoperative Pringle maneuver, the duration of liver parenchymal transection, perioperative complications, and postoperative morbidity and mortality were all evaluated. RESULTS: Fifty minor and ninety-five major liver resections were performed. The mean intraoperative blood loss was 251 mL, with a transfusion rate of 11.7%. The Pringle maneuver was necessary in 12 patients (8.3%). The mean duration for parenchymal transection was 51.75 minutes. There were 47 patients (32.4%) with postoperative complications. There is no mortality within 30 days after surgery. CONCLUSIONS: Radiofrequency ablation-assisted liver re-section permits both major and minor liver resections with minimal blood loss and without occlusion of hepatic inflow. Furthermore it decreases the need for blood transfusion and reduces morbidity and mortality.

    Brown syndrome, characterized by a limitation of elevation in adduction and positive forced duction testing, is usually unilateral but occurs bilaterally in 10% of all cases. It may present as a congenital condition in one eye and develop in the other eye with no apparent cause. We present a case of bilateral Brown syndrome in which the right eye became involved within 1 year of surgery on the left eye for congenital Brown syndrome.

    Full Text Available Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Although poorly understood, interstitial lung disease has been reported as a possible complication of tumor necrosis factor alpha inhibitors. We report a case of interstitial lung disease in a 64-year-old man with psoriasis 3 weeks after the initiation of infliximab treatment. The patient had received two fortnightly infusions of infliximab following a short course of methotrexate. Thoracic computed tomography showed bilateral ground glass and interstitial infiltrates, while the results of microbiology and immunologic workup were negative. Likewise, bronchoalveolar lavage detected neither typical nor atypical pathogens. Infliximab-induced interstitial lung injury was suspected and corticosteroid therapy was administered which resulted in rapid clinical and radiological improvement. This is one of the few reported cases of interstitial lung disease due to infliximab in the psoriasis population. The patient had no pre-existing lung pathology, while his previous exposure to methotrexate was minimal and was not temporally associated with the induction of interstitial lung disease.

    In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally symmetric and aesthetically superior to the osteoplastic reconstruction. The technical details are discussed, and the long term functional and aesthetic results are presented.

    Full Text Available Total shoulder arthroplasty (TSA is successful in providing pain relief and functional improvements for patients with shoulder arthritis. Outcomes are directly correlated with implant position and fixation, which ultimately affects wear and longevity. Metal-backed glenoid components were introduced as an alternative to the standard cemented glenoid fixation. Early loosening and cavitary glenoid bone loss has been reported as a major complication associated with these metal-backed glenoids, which presents the surgeon with a challenging revision situation. Furthermore, failure of bilateral TSA in patients with metal-backed glenoids is extremely rare. We present two patients with early failure of bilateral TSA secondary to loosening of the metal-backed glenoids. Both patients had significant glenoid bone loss and were treated with four different types of revision techniques. A description of treatments and outcomes of both patients are reported along with the simple shoulder test and American Shoulder and Elbow Surgeons scores. One patient underwent revision to bilateral reverse prosthesis and experienced a much-improved outcome in comparison to the patient revised to a hemiarthroplasty and resection arthroplasty, for each shoulder respectively. In patients who present with failed TSA, revision to a reverse prosthesis with or without staged glenoid bone graft should be considered as an option of treatment. It is also important to rule out infection with intraoperative tissue biopsy before proceeding to revision surgery. However, in patients with catastrophic glenoid bone loss, both hemiarthroplasty and resection arthroplasty can provide an alternative treatment option, but they are associated with a poorer functional outcome and pain relief.

    Full Text Available BACKGROUND: The aim of this meta-analysis is to evaluate the impact of transthoracic resection on long-term survival of patients with GEJ cancer and to compare the postoperative morbidity and mortality of patients undergoing transthoracic resection with those of patients who were not undergoing transthoracic resection. METHOD: Searches of electronic databases identifying studies from Medline, Cochrane Library trials register, and WHO Trial Registration etc were performed. Outcome measures were survival, postoperative morbidity and mortality, and operation related events. RESULTS: Twelve studies (including 5 RCTs and 7 non-RCTs comprising 1105 patients were included in this meta-analysis, with 591 patients assigned treatment with transthoracic resection. Transthoracic resection did not increase the 5-y overall survival rate for RCTs and non-RCTs (HR = 1.01, 95% CI 0.80- 1.29 and HR = 0.89, 95% CI 0.70- 1.14, respectively. Stratified by the Siewert classification, our result showed no obvious differences were observed between the group with transthoracic resection and group without transthoracic resection (P>0.05. The postoperative morbidity (RR = 0.69, 95% CI 0.48- 1.00 and OR = 0.55, 95% CI 0.25- 1.22 and mortality (RD = -0.03, 95% CI -0.06- 0.00 and RD = 0.00, 95% CI -0.05- 0.05 of RCTs and non-RCTs did not suggest any significant differences between the two groups. Hospital stay was long with thransthoracic resection (WMD = -5.80, 95% CI -10.38- -1.23 but did not seem to differ in number of harvested lymph nodes, operation time, blood loss, numbers of patients needing transfusion, and reoperation rate. The results of sensitivity analyses were similar to the primary analyses. CONCLUSIONS: There were no significant differences of survival rate and postoperative morbidity and mortality between transthoracic resection group and non-transthoracic resection group. Both surgical approaches are acceptable, and that one offers no clear advantage over

    Multiple or second primary lung cancers can develop at any sites in the lung with same or different histologic types, synchronously and/or metachronously. In case of metachronous occurrence of the second primary lung cancer, it is easy to confuse with the primary lung cancer as a recurrence of precedent lung malignancy treated successfully or metastasis. Previous reports have demonstrated that majority of the second primary lung malignancies have same histologic types regardless of their developing time and location. However, the repeated occurrence of the second primary lung malignancy, in particular with the different histologic features, is a very rare condition.A 62-year-old male who had past history of squamous cell carcinoma treated with surgery and adjuvant chemotherapy and the recurrence of lung malignancy on the trachea, which was also resected successfully visited our hospital due to blood tinged sputum. Evaluation using bronchoscopy and chest computed tomography revealed the tracheal mass looked similar grossly to the previous recurred tracheal mass that was resected surgically. Unexpectedly, the newly developed tracheal mass was confirmed as small cell lung cancer, the different histologic type from previous ones.In this report, we describe an interesting case of subsequent occurrence of second primary lung cancers showing histologic shifting at different sites in trachea, suggesting that it is important for physician to make an effort to identify the histologic characteristics of second primary lung cancers for the correct and adequate treatment no matter what they exhibit similar gross morphology.

    Full Text Available Background and objective Localization of pulmonary ground glass small nodule is the technical difficulty of minimally invasive operation resection. The aim of this study is to evaluate the value of intraoperative computed tomography (CT-guided localization using a hook-wire system for small ground glass opacity (GGO in minimally invasive resection, as well as to discuss the necessity and feasibility of surgical resection of small GGOs (<10 mm through a minimally invasive approach. Methods The records of 32 patients with 41 small GGOs who underwent intraoperative CT-guided double-thorn hook wire localization prior to video-assisted thoracoscopic wedge resection from October 2009 to October 2013 were retrospectively reviewed. All patients received video-assisted thoracoscopic surgery (VATS within 10 min after wire localization. The efficacy of intraoperative localization was evaluated in terms of procedure time, VATS success rate, and associated complications of localization. Results A total of 32 patients (15 males and 17 females underwent 41 VATS resections, with 2 simultaneous nodule resections performed in 3 patients, 3 lesion resections in 1 patient, and 5 lesions in a patient. Nodule diameters ranged from 2 mm-10 mm (mean: 5 mm. The distance of lung lesions from the nearest pleural surfaces ranged within 5 mm-24 mm (mean: 12.5 mm. All resections of lesions guided by the inserted hook wires were successfully performed by VATS (100% success rate. The mean procedure time for the CT-guided hook wire localization was 8.4 min (range: 4 min-18 min. The mean procedure time for VATS was 32 min (range: 14 min-98 min. The median hospital time was 8 d (range: 5 d-14 d. Results of pathological examination revealed 28 primary lung cancers, 9 atypical adenomatous hyperplasia, and 4 nonspecific chronic inflammations. No major complication related to the intraoperative hook wire localization and VATS was noted. Conclusion Intraoperative CT-guided hook wire

    Renal sonography is a routine step in the evaluation of new onset renal failure. When renal masses are discovered in this setting, functional imaging may be critical. We report a case of bilateral renal masses in a girl with urinary tract infection and renal insufficiency found to have vesicoureteral reflux. Renal scintigraphy revealed these masses to be the only remaining functional renal tissue, preventing potentially harmful resection. (orig.)

    Primary lung sarcomas are uncommon histologic types of primary lung cancer and presents a wide spectrum of clinical behaviour. Nine patients treated at Antoine Lacassagne Cancer Center between 1982 and 1995 were studied. The median age was 63 years (range, 35-73 years) and the most common histologic types were malignant fibrous histiocytoma (four) and leiomyosarcoma (three). All of them underwent surgery, six patients had a complete surgery and three patients incomplete resections. The median overall survival for all patients was 36 months. In the subgroup of patients with initial complete resection, the median survival was significantly longer (47 months) than in the subgroup of patients with incomplete resection (6 months) (Prank test). Moreover, two patients had a second complete resection for ipsilateral lung relapse and were long survivors (overall survival of 58 and 83 months, respectively). The ability to achieve a complete second surgery stress the possible benefit of an early detection of local recurrence. Because no specific symptom was linked with the local relapse, a systematic CT scan every 2 or 3 months could be required.

    Purpose: Neural progenitor cells in the subventricular zone (SVZ) have a controversial role in glioblastoma multiforme (GBM) as potential tumor-initiating cells. The purpose of this study was to examine the relationship between radiation dose to the SVZ and survival in GBM patients. Methods and Materials: The study included 116 patients with primary GBM treated at the Johns Hopkins Hospital between 2006 and 2009. All patients underwent surgical resection followed by adjuvant radiation therapy with intensity modulated radiation therapy (60 Gy/30 fractions) and concomitant temozolomide. Ipsilateral, contralateral, and bilateral SVZs were contoured on treatment plans by use of coregistered magnetic resonance imaging and computed tomography. Multivariate Cox regression was used to examine the relationship between mean SVZ dose and progression-free survival (PFS), as well as overall survival (OS). Age, Karnofsky Performance Status score, and extent of resection were used as covariates. The median age was 58 years (range, 29-80 years). Results: Of the patients, 12% underwent biopsy, 53% had subtotal resection (STR), and 35% had gross total resection (GTR). The Karnofsky Performance Status score was less than 90 in 54 patients and was 90 or greater in 62 patients. The median ipsilateral, contralateral, and bilateral mean SVZ doses were 48.7 Gy, 34.4 Gy, and 41.5 Gy, respectively. Among patients who underwent GTR, a mean ipsilateral SVZ dose of 40 Gy or greater was associated with a significantly improved PFS compared with patients who received less than 40 Gy (15.1 months vs 10.3 months; P=.028; hazard ratio, 0.385 [95% confidence interval, 0.165-0.901]) but not in patients undergoing STR or biopsy. The subgroup of GTR patients who received an ipsilateral dose of 40 Gy or greater also had a significantly improved OS (17.5 months vs 15.6 months; P=.027; hazard ratio, 0.385 [95% confidence interval, 0.165-0.895]). No association was found between SVZ radiation dose and PFS

    Therapeutic endoscopy plays a major role in the management of gastrointestinal (GI) neoplasia.Its indications can be generalized into four broad categories; to remove or obliterate neoplastic lesion,to palliate malignant obstruction, or to treat bleeding.Only endoscopic resection allows complete histologicalstaging of the cancer, which is critical as it allowss tratification and refinement for further treatment.Although other endoscopic techniques, such asablation therapy, may also cure early GI cancer, they can not provide a definitive pathological specimen.Early stage lesions reveal low frequency of lymph node metastasis which allows for less invasive treatments and thereby improving the quality of life when compared to surgery. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are now accepted worldwide as treatment modalities for early cancers of the GI tract.

    2012-01-01

    Background and Objectives: Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. Methods: Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. Results: Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5×3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. Conclusion: Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

    Although epidural analgesia is routinely used in many institutions for patients undergoing hepatic resection, there are unresolved issues regarding its safety and efficacy in this setting. We performed a review of papers published in the area of anaesthesia and analgesia for liver resection surgery and selected four areas of current controversy for the focus of this review: the safety of epidural catheters with respect to postoperative coagulopathy, a common feature of this type of surgery; analgesic efficacy; associated peri-operative fluid administration; and the role of epidural analgesia in enhanced recovery protocols. In all four areas, issues are raised that question whether epidural anaesthesia is always the best choice for these patients. Unfortunately, the evidence available is insufficient to provide definitive answers, and it is clear that there are a number of areas of controversy that would benefit from high-quality clinical trials.

    Gastric diverticula are rare and usually asymptomatic. This report, however, describes two examples of symptomatic gastric diverticula successfully treated by laparoscopic resection. Both patients were male and in their sixth decade of life. One patient was relatively healthy with no past medical history, whereas the other patient had chronic pain issues and at presentation was also undergoing evaluation for hyperaldosteronism. The patients presented with gastrointestinal symptoms, including nausea, emesis, abdominal pain, and change in bowel function. In both cases, a gastric diverticulum was identified by CT scan, and precise anatomic position was determined by upper endoscopy. After discussion with the treating teams, including a gastroenterologist and surgeon, surgical treatment and resection was elected. Successful laparoscopic removal was accomplished in both patients, and they were discharged home after tolerating liquid diets. Both patients reported resolution of their abdominal symptoms at follow-up. PMID:24680154

    Objective To present the diagnosis and management of anastomotic leakage after colon resection. Methods Early diagnosis and urgent therapeutic intervention are required in order to avert life-threatening conditions that may be caused by anastomotic leakage. Results The diagnosis of anastomotic leakage is based on clinical features, peripheral blood investigations and abdominal computed tomography (CT) scan. Major leaks are defined by symptoms of peritonitis and septicaemia due to leakage. Major leaks should be managed operatively. Minor leaks can be managed conservatively with successful outcomes. Conclusion Leakage of colonic anastomosis remains the most serious complication after colon resection. It is a major cause of postoperative morbidity and mortality. A high index of suspicion is required in order to detect early, nonspecific signs of a leakage and urgent surgical intervention is usually required to avert life-threatening events.

    A rare case is presented of a 58-year-old woman who developed a bronchopleural fistula following a laparoscopic liver resection for a colorectal metastasis. The bronchopleural fistula was finally diagnosed when after repeated admissions for chest infections, the patient coughed up surgical clips. We propose a management plan based on our experience and hope this case report will add to the scarce reports of postoperative bronchopleural fistula cases in the literature.

    Conclusion: The FLA is a versatile approach and is useful for a variety of lesions located ventrolateral to the brainstem and upper cervical cord. It allows adequate exposure with minimal retraction. Most of the foramen magnum meningiomas can be excised either without or with only partial resection of the condyle. The transjugular process approach to the jugular foramen (JF is effective for JF tumors without the necessity of facial nerve transposition.

    Hallucinations can be auditory, visual, tactile, gustatory, or olfactory, and can be caused by psychiatric (such as schizophrenia and depression), neurological (such as cerebrovascular accidents, neoplasia, and infection), or endocrine and metabolic disorders. Musical hallucinations related to neurological disorders are rare. The authors present a case of a patient with a right insular glioma who developed transient musical hallucinations after microsurgical resection of the tumor.

    A 42-year-old woman presented to a regional hospital emergency room with palpitations and was found to be in ventricular tachycardia. Chest radiography demonstrated a massively enlarged cardiac silhouette. Echocardiography and cardiac magnetic resonance imaging demonstrated a mass within the left ventricular free wall, consistent with a cardiac fibroma. The patient proceeded to have surgical resection of the mass. Left ventricular function was preserved postoperatively.

    The increased relevance of liver surgery and transplantation as a therapeutic modality over the last two decades mandates the development of novel strategies to improve liver regeneration. Here we studied whether erythropoietin (EPO) improves liver regeneration after hepatectomy in pigs. Eighteen female pigs underwent laparoscopic left lateral liver resection and were allocated randomly into three groups. No EPO was administered to the control group (group 1, n=6). Group 2 (...

  17. Cephalic Aura after Frontal Lobe Resection

    OpenAIRE

    A cephalic aura is a common sensory aura typically seen in frontal lobe epilepsy. The generation mechanism of cephalic aura is not fully understood. It is hypothesized that to generate cephalic aura more extensive cortical areas need to be excited. Here we report a patient who started to have cephalic aura after right frontal lobe resection. MEG showed interictal spike and ictal change during cephalic aura, both of which were distributed on right frontal region, and the latter involved much m...

  18. Accuracy and precision of perfusion lung scintigraphy versus {sup 133}Xe-radiospirometry for preoperative pulmonary functional assessment of patients with lung cancer

    Purpose: This study sought to determine whether {sup 133}Xe-radiospirometry (XRS) successfully selects patients able to undergo lung resection without postoperative respiratory complications and whether perfusion lung scintigraphy (PLS) is likely to provide a similar selection of patients for certain tumour stages. Methods: Two hundred and eighty-four patients with resectable lung cancer underwent preoperative assessment of postoperative forced expiratory volume in 1 s (FEV{sub 1}) by XRS and PLS. Correlations, Bland and Altman analysis and contingency tables were used to analyse the difference between the two predictive techniques. One hundred and sixty patients underwent lung resection on the basis of XRS preoperative testing only. None of them developed respiratory insufficiency. Despite a close correlation, the limits of agreement between predicted FEV{sub 1} by XRS and PLS exceeded {+-}0.3 l/s. For tumour stages T1Nx and T2N0, PLS underestimated postoperative FEV{sub 1} whereas it overestimated this parameter for stage III. XRS accurately selects patients able to undergo lung resection without postoperative pulmonary insufficiency. The agreement between XRS and PLS is unacceptable. When only PLS is available, higher thresholds for patients with stage III cancers and lower thresholds for those with stage I cancers should be used to decide on operability. (orig.)

    The assessment of the regional match between alveolar ventilation and perfusion in critically ill patients requires simultaneous measurements of both parameters. Ideally, assessment of lung perfusion should be performed in real-time with an imaging technology that provides, through fast acquisition of sequential images, information about the regional dynamics or regional kinetics of an appropriate tracer. We present a novel electrical impedance tomography (EIT)-based method that quantitatively estimates regional lung perfusion based on first-pass kinetics of a bolus of hypertonic saline contrast. Pulmonary blood flow was measured in six piglets during control and unilateral or bilateral lung collapse conditions. The first-pass kinetics method showed good agreement with the estimates obtained by single-photon-emission computerized tomography (SPECT). The mean difference (SPECT minus EIT) between fractional blood flow to lung areas suffering atelectasis was -0.6%, with a SD of 2.9%. This method outperformed the estimates of lung perfusion based on impedance pulsatility. In conclusion, we describe a novel method based on EIT for estimating regional lung perfusion at the bedside. In both healthy and injured lung conditions, the distribution of pulmonary blood flow as assessed by EIT agreed well with the one obtained by SPECT. The method proposed in this study has the potential to contribute to a better understanding of the behavior of regional perfusion under different lung and therapeutic conditions.
