Objective
To summarize the preliminary effectiveness of surgical treatment of Erdheim-Chester disease (ECD), so as to improve the understanding of the disease by orthopedic surgeons.
Methods
The clinical data of 9 patients with ECD between December 2012 and October 2017 were retrospectively analysed. There were 6 males and 3 females with an median age of 42 years (range, 8-61 years). The disease duration was 4-59 months (mean, 39 months). There were 2 cases of multiple lesions, including 1 case involving soft tissue of the buttocks and bilateral tibia, 1 case involving the sinus, skull base, and proximal right tibia; 7 cases with single lesion, including 3 cases of right femoral neck, 1 case of proximal right tibia, 1 case of right humerus, and 2 cases of ribs. Nine patients were diagnosed according to clinical manifestations, imaging examination, and pathological diagnosis. Four patients underwent needle biopsy before operation and 5 patients were diagnosed by postoperative pathology examination. Five cases underwent lesional scraping and internal fixation, 1 case underwent bone scraping and bone grafting, and 3 cases underwent lesion resection. One of the multiple lesions was treated with interferon and hormone.
Results
Nine patients underwent the surgery safely. There was no fever, wound exudation, infection, etc., and the incisions healed by first intention. All the patients were followed up 4-59 months with an average of 31.4 months. One patient with bilateral tibia and hip soft tissue involvement continued to receive medical treatment, and the tumor was controlled without significant increasing. The remaining 8 patients were examined for X-ray films at 3, 6, and 12 months after surgery, the bone has been fused and the steel plate and intramedullary nail were firmly fixed, and no tumor recurrence was observed. At 1 year after surgery, the pain symptoms of the patients improved and returned to normal life; 3 of them who involving the right femoral neck walked freely, and the quality of life improved significantly.
Conclusion
ECD patients can achieve the purpose of eliminating lesions and relieving pain after surgical treatment, and the surgical treatment has the advantages of quick relief of pain, improved quality of life, small side effects, and low economic cost when compared with medical treatment.
Objective To explore the feasibility and safety of endoscopic thyroidectomy via chest-breast approachand summarize the operation skill. Method The clinical data of 40 cases performed endoscopic thyroidectomy via chest-breast approach from August 2010 to August 2012 in this hospital were analyzed retrospectively. Results The endoscopic thyroidectomies via chest-breast approach were successfully performed in all 40 patients without conversion to open surgery, massive haemorrhage, hypercapnia, severe subcutaneous emphysema, cutaneous necrosis on chest,permanent impairment of recurrent laryngeal nerve, and permanent hypoparathyroidism. One case of hoarseness was found on 2d after operation, who returned to normal after symptomatic treatment. One case of numbness in the extremitieshappened on day 2 after operation and the symptom was relieved through intravenous and oral administration of calcium treatment in 3d. One case of cutaneous tightness on chest happened, and it was spontaneous remission in a month. The operation time was (102±28.4) min (55-182 min), intraoperative bleeding was (46±16.6) mL (30-106 mL), and the drainage tube was removed postoperative 2-7d with an average (4±2.2) d, the postoperative hospitalization was 3-8 d with an average (4±1.1) d. All of the cases were followed-up after operation without low calcium, low parathyroid hormone, hoarseness, and local goiter recurrence. Two cases of hypoparathyroidism returned to normal after oral thyroxine dose adjustment. All the patients were satisfied with the cosmetic results. Conclusions The endoscopic thyroidectomy via chest-breast approach is safe and feasible with good cosmetic results. The subcutaneous Y tunnel, the “upper yellow middle white lower red” appearance on the chest, and the landmark of inverse trapezium on the neck are the key points for creation of operation compartment. Sufficient exposure, stepwise procedure, blunt dissection combined with sharp dissection in the precise gap are the surgical skills for endoscopic thyroidectomy.
Cardiopulmonary resuscitation (CPR) is a very important treatment after cardiac arrest. The optimal treatment strategy of CPR is uncertain. With the accumulation of clinical medical evidence, the CPR treatment recommendations have been changed. This article will review the current hot issues and progress, including the pathophysiological mechanisms of CPR, how to achieve high-quality chest compression, how to achieve CPR quality monitoring, how to achieve optimal CPR for different individuals and how to use antiarrhythmic drugs.
ObjectiveWe aimed to further investigate the feasibility of using small bore chest tubes or even without chest tube insertion after da Vinci robot-assisted thoracic surgery.
MethodsWe retrospectively analyzed initial 70 patients between September 12, 2014 and March 30, 2015 as a control group at the department of thoracic surgery, the First Affiliated Hospital of Zhejiang University, and proposed four schemes. There are 31 males and 39 females with mean age of 57.1±9.8 (ranged from 30-80 years). We applied those four schemes for the last 30 patients as an experimental group. There are 12 males and 18 females with mean age of 58.8±8.1 (ranged 42-73 years).
ResultsThe days in hospital after surgery ranged 2-25 days and there was no severe complication. After the surgery, the pain scores of the trial group are lower than that of the control group. And the schemes 1 and schemes 2 of trial group reduced significantly than the control group (P<0.05). There is no significant difference of the rate of the complication caused by poor drainage between the trial group and the control group (P>0.05). But the pain score after surgery is lower than that of the control group (P<0.05).
ConclusionOptimizing thoracic drainage strategy after da Vinci robot-assisted thoracic surgery is safe, possible and helpful to relieve postoperative pain.
Surgical management of non-small cell lung cancer (NSCLC) invading chest wall is the combination of pulmonary resection, lymphadenectomy and chest wall resection and reconstruction. Hitherto the surgical procedures include combination of thoracotomy and video-assisted thoracoscopic surgery (VATS), thoracotomy, and VATS. The result of the surgery leads to a defect in the chest wall. Therefore, the requirements of the technique and material are relatively high with no consensual standard. This review describes the definitions, indications, materials, prognostic factors, and recent progress in surgical techniques.
Mediastinal and chest wall tumors contain various benign and malignant tumors. In order to further standardize the whole-course diagnosis and treatment of mediastinal and chest wall tumors, the consensus was formulated through discussion by the expert group. Based on the clinical diagnosis and treatment experience and various prospective and retrospective studies, the consensus was formed.
Objective
To investigate the characteristics on chest high-resolution computed tomography (HRCT) of patients with interstitial pneumonia with positive myeloperoxidase antineutrophil cytoplasmic antibody (MPO-IP).
Methods
The extent of fibrosis and subtypes of emphysema on HRCT of MPO-IP patients were retrospectively analyzed and compared with idiopathic pulmonary fibrosis (IPF) cases admitted in the same period.
Results
From July 2014 to March 2016, 10 patients was diagnosed with IPF and 10 patients was diagnosed with MPO-IP. Emphysema was not different between two groups. Among the MPO-IP patients, 8 patients presented with a usual interstitial pneumonia (UIP) pattern. There existed statistical difference in the bronchial bifurcation level, the fibrosis score of lungs in the MPO-IP patients presented with UIP was lower than that in the IPF patients.
Conclusions
UIP is the predominant radiologic type of MPO-IP patients. Fibrosis in IPF is more serious than that in MPO-IP with UIP. Paraseptal and centrilobular emphysema are main forms in MPO-IP patients.
Precise segmentation of lung field is a crucial step in chest radiographic computer-aided diagnosis system. With the development of deep learning, fully convolutional network based models for lung field segmentation have achieved great effect but are poor at accurate identification of the boundary and preserving lung field consistency. To solve this problem, this paper proposed a lung segmentation algorithm based on non-local attention and multi-task learning. Firstly, an encoder-decoder convolutional network based on residual connection was used to extract multi-scale context and predict the boundary of lung. Secondly, a non-local attention mechanism to capture the long-range dependencies between pixels in the boundary regions and global context was proposed to enrich feature of inconsistent region. Thirdly, a multi-task learning to predict lung field based on the enriched feature was conducted. Finally, experiments to evaluate this algorithm were performed on JSRT and Montgomery dataset. The maximum improvement of Dice coefficient and accuracy were 1.99% and 2.27%, respectively, comparing with other representative algorithms. Results show that by enhancing the attention of boundary, this algorithm can improve the accuracy and reduce false segmentation.
ObjectiveTo compare clinical results between single and double chest tube applications after lung cancer resection, and explore the role of single chest tube in postoperative fast track recovery.
MethodNinety-three patients with lung cancer who underwent lobectomy between March and December of 2009 in West China Hospital of Sichuan University were included in this study. All the patients were divided into a single-tube group including 46 patients (39 males and 7 females) with their age of 58.4±9.5 years, and a double-tube group including 47 patients (32 males and 15 females) with their age of 58.2±9.0 years. Drainage amount, duration, postoperative hospital stay, and incidences of pneumothorax and pleural effusion after removal of chest tubes were compared between the 2 groups.
ResultsThe percentage of patients undergoing complete video-assisted thoracic surgery (VATS) of the double-tube group was significantly higher than that of the single-tube group, and the percentage of patients undergoing thoracotomy of the double-tube group was significantly lower than that of the single-tube group (P < 0.05). Drainage amount of the double-tube group was significantly larger than that of the single-tube group (824.4±612.5 ml vs. 510.7±406.7 ml, P < 0.05). There was no statistical difference in drainage duration, postoperative hospital stay, the incidences of subcutaneous emphysema, pneumothorax, pleural effusion or re-insertion of chest drain between the 2 groups (P > 0.05).
ConclusionClinical results of single chest tube is better than or equivalent to those of double chest tubes after lung cancer resection, and drainage duration of single chest tube application might be shorter.
Objective To optimize image quality and radiation dose of infant chest digital radiography and to explore feasibility of reducing tube voltage and adjusting according to infant chest area. Methods 0 to 3-year-old infants were randomly divided into two average groups of 0- and 1-3 year-old, and then each age group was randomly assigned to optimization and control groups in digital radiography. Measurement of radiation dose used dose area product (DAP). Mean DAP between groups was compared by using t test, and the image quality of optimization was compared by rank sum test. Results A total of 400 cases of 0 to 3-year-old infants were identified, and finally 391 cases of infants anteroposterior chest image were included, including 196 cases in the optimization group (0-years: n=91; 1-3 years: n=105) and 195 cases in the control group (0-years: n=103; 1-3 years: n=92). The results showed: there were significant differences in the mean DAP in 0-years, 1-3 years and total infants between the optimization group and the control group (all P valuelt;0.05). The DAP of the optimization group was lower, and reduction of DAP was approximately 21.6% compared to the control subject. The Wilcoxon signed-rank test showed the difference of subjective evaluation of image quality was significantly different (P=0.000). High-quality image of the optimization group increased approximately 43.9% more than control subject. Conclusion Reducing tube voltage and adjusting according to infants chest area can not only reduce the radiation dose but also improve image quality in digital radiography.
