ABSTRACT
Objective:To investigate the anatomical variation of the T3 sympathetic ganglia and its relationship with surgical outcomes in primary palmar hyperhidrosis.Methods:A total of 86 patients with primary palmar hyperhidrosiswho underwent R4 sympathicotomy from November 2017 to September 2018 were prospectively enrolled. The anatomical variation of T3 sympathetic ganglia was observed by fluorescence thoracoscopy. The therapeutic effect and side effect were followed up after operation.The relationship between T3 anatomical variation and postoperative effect was analyzed.Results:82.6% of T3 ganglion had no anatomic variation, 17.4% of T3 ganglion shifted down to the surface of the fourth rib or intercostal space. After 1 month of follow-up, the therapeutic effect was: overly dry 2.1%, dry 39.4%, mild moist 57.0%, moist 1.4% innormalside, and 13.3%, 53.3%, 33.3%, 0 in the variation side respectively. Mann- Whitney U test showed statistically significant difference between the two groups( P=0.004). After 1 year of follow-up, the effect was 0, 36.5%, 56.9%, 6.6% in normal side, and 0, 33.3%, 63.0%, 3.7% in the variation side respectively. There was no significant difference between the two groups by Mann- Whitney U test( P=0.869). Conclusion:Fluorescence thoracoscopy showed that the variation rate of the position of T3 sympathetic ganglion was 17.4%. Postoperatively, patients with the downshift variation of T3 sympathetic ganglion have drier hands in short-term follow-up.
ABSTRACT
@#This guideline systematically reviewed and summarized the 20 years' clinical and basic research experience of minimally invasive treatment of palmar hyperhidrosis (PH) in China, and discussed the hot and difficult issues of minimally invasive treatment of PH. We have formed a new consensus of PH in terms of its definition, clinical manifestations, diagnostic criteria and classification, surgical indications and contraindications, surgical procedures and management of complications, especially in the area of postoperative compensatory hyperhidrosis (CH). This guideline confirmed that endoscopic thoracic sympathicotomy (ETS) was the most effective treatment for PH and that CH was the most common side effect. In order to reduce the incidence of CH, eliminate patient's distress and improve patient's satisfaction, the guideline emphasized that the keys to prevent CH were to pay attention to pre-operative interview, communicate with patients, select patients carefully, avoid the enlargement of operative indication and optimize operative procedure. This guideline also introduced the advantages and disadvantages of various methods to reduce the incidence of CH. We provided this authoritative guidance document in order to avoid the surgical risk, strengthen the perioperative management and improve the sugery effect.
ABSTRACT
Raynaud Syndrome(RS) is a kind of paroxysmal digital ischemic disease whose typical symptom is characteristic tricolor change featuring pallor,cyanosis,and erythema induced by cold or emotion changing.The pathogenesis of RS is still not entirely clear,and there is no radical treatment.In recent years,endoscopic thoracic sympathectomy (ETS) for Raynaud Syndrome is gradually applied.ETS produces a high rate of initial relief,and has lower risk and technical difficulty compared with other surgical options,while its poor long-term outcome can't be ignored.There is currently a lack of a large number of clinical controlled trials between different operations,and there is still a need for further improved surgical procedures and accurate postoperative evaluation criteria.In this review,the recent advances of ETS is summarized.

ABSTRACT
Objective To analyze the causes of misdiagnosis of esophageal leiomyoma.Methods The clinical data of 20 patients who were preoperatively misdiagnosed as esophageal leiomyoma at our hospital in 16 years were retrospectively analyzed.There were 11 males(55%) and 9 females(45%) with a mean age of(45.9 ± 16.4) years(range, 13-71 years).The initial presentations were obstructive symptoms in 12 patients(60%).CT imaging were performed in 9 patients(45%), of which 4 cases were enhanced CT(20%).Results The misdiagnosed patients included 5 cases of extraesophageal lesions(4 cases of paraesophageal lymph node tuberculosis and 1 case of lymph node hyperplasia), 8 cases of begin interstitial diseases(3 cases of neurinoma, 3 cases of inclusion cyst, 2 cases of angioma), 5 cases of malignant interstitial diseases(4 cases of GIST, 1 case of PNET), and 2 cases of esophageal cancer.The 4 cases of esophageal tuberculosis were misdiagnosed due to the absence of CT examination.The patients with esophageal cancer were treated with esophageal resection and reconstruction without clear staging of the tumor.This might be associated with the neglection of the rapid symptom development and the characteristic lumen stenosis under the gastroscope.The characteristic mucosal ulcer in patients with highly malignant GIST was overlooked.The disease relapsed postoperatively because only tumor enucleation was performed.Conclusion Preoperative diagnosis of esophageal leiomyoma is not uncommon.This disease is most often misdiagnosed as paraesophageal lymph node tuberculosis or esophageal GIST.CT examination is useful in distinguishing esophageal leiomyoma and paraesophageal lymph node tuberculosis.The roles of reoperation and adjuvant therapy in the surgical treatment of esophageal leiomyoma need further investigation.
ABSTRACT
Familial spontaneous pneumothorax(FSP) is a specific type of primary spontaneous pneumothorax.FSP means there are more than one individuals develop pneumothorax and is a rare inherited disease.FSP is different from primary spontaneous pneumothorax in several clinical manifestations.So far the genetic basis and inheritance pattern of this disease are not clear.Progress in this field are reviewed here.
ABSTRACT
Objective Analyze the clinical feature of patients failed for diagnosis through endobronchial ultrasound transbronchial needle aspiration(EBUS-TBNA).Optimize the indication and increase diagnosis rate of EBUS-TBNA.Methods A total of 669 patients failed for diagnosis of EBUS-TBNA were included.Fifty-three of them(7.92％) were not exactly diagnosed.Perioperation clinical data and clinical feature were collected and evaluated based on specific disease,lesion location,size and operator' s experience.Results The undiagnosis rate was higher in lymphoma (77.78％),tuberculosis (23.08％) and sarcoidosis(9.09％) when analyzed from specific diseases.If the lesion location was taken into consideration,15.38％ upper paratracheal lymph nodes(R2) could not be diagnosed exactly by EBUS-TBNA,and the bilateral hilar lymph nodes(15.00％ for right,11.54 for left) were followed.Size of the lesion was not associated with the diagnosis rate.The operator's experience could also affect the results.The undiagnosis rate was highest in the first 10 cases among all operators.After at least 10 EBUS-TBNA processes,the undiagonsis rate stayed near 7.50％,which was close to the average.Conclusion It is necessary to select suitable indications for EBUS-TBNA based on the disease,lesion location and operatior experience,and cooperate with mediastinoscopy to rise diagnosis rate.
ABSTRACT
Objective To summarize and analyze the clinical features of familial spontaneous pneumothorax.Methods During April 2001 to March 2013,the clinical data of 65 familial spontaneous pneumothorax from 21 families were retrospected and summarized.Contrasting with previous literature,the clinical features of familial spontaneous pneumothorax were analyzed.Results Patients in one family vary from 2 to 6,average 3.1.Families in which patients distribute in one generation,two generations and three generations were 19.0％,61.9％ and 19.0％ respectively.Male/female ratio of patients was.Mean onset age was 36.2 ± 12.2 ; Body mass index (BMI) of male and female patients were 24.0 ± 2.6 and 22.6 ± 3.0.32.7％ patients suffered bilateral pneumothorax.The recurrence rate after non-operative treatment was 50.0％.Conclusion Compared with sporadic spontaneous pneumothorax,Familial spontaneous pneumothorax has the following features:The incidence in man and woman was more similar; The onset age was older; Lanky body is less common; More were bilateral pneumothorax; Multiple pulmonary bullae are more common; Patients with non-surgical treatment have a higher recurrence rate.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical characteristics and follow up record of patients with synchronous multiple lung cancers (SMLC).</p><p><b>METHODS</b>The medical records of 1 868 lung cancer patients who underwent surgical treatments From January 2007 to December 2014 were reviewed, in which 103 patients were diagnosed SMLC by Martini and American College of Chest Physicians modified guideline. The average age was 60.5 years, including 34 male and 69 female patients. According to consolidation/tumor ratio (CTR) on thin-section computed tomography, 103 cases were classified into three groups: group A (multiple ground-glass opacities, CTR ≤ 50%), group B (with one solid dominant nodules, CTR > 50%), group C (with two solid dominant nodules). The surgical procedure was determined according to CT findings and respiratory function. The Kaplan-Meier method was used to analyze the duration of recurrence-free survival (RFS) and over-all survival (OS), and differences were assessed using the Log-rank test. Multivariate analysis using the Cox proportional hazards models was used to assess the potential independent effects on RFS or OS.</p><p><b>RESULTS</b>There were 38 patients in group A (36.9%), 40 patients in group B (38.8%) and 25 patients (24.3%) in group C. More female (73.7% vs. 48.0%, χ² = 4.291, P = 0.038), less smoker (21.1% vs. 44.0%, 2 = 3.770, P = 0.052), younger (56.2 years old vs. 65.9 years old, t = -4.172, P = 0.000) and less tumor size (1.24 cm vs. 2.31 cm, t = -4.573, P = 0.000) patients in group A than in group C. The 3, 5-year RFS were 80.3% and 64.9% for all patients, respectively. The 3, 5-year OS were 87.3% and 68.6% for all patients, respectively. The 3, 5-year RFS were 100% and 100% in group A, 77.7% and 51.8% in group B, 59.6% and 44.7% in group C (P = 0.029). No significance were found in OS between the three groups (P = 0.214). Multivariate Cox analysis demonstrated that size of dominant nodule larger than 2 cm (HR = 4.475, 95% CI: 1.138 to 17.604, P = 0.032) is associated with poor prognosis, whereas postoperative chemotherapy did not affect RFS.</p><p><b>CONCLUSIONS</b>Multifocal ground-glass opacities and multiple solid lung cancers are different in nature. RFS of patients with SMLC is strongly affected tumor size. Surgical resection is effective and should be performed specifically to patients.</p>

Objective To analyze the delay in diagnosis and treatment lung cancer expressed as solitary pulmonary nodules (SPN) found by physical examination,and to discover the relative reasons and consequence for future improvement.Methods From January 2000 to August 2011,162 patients (93 males,69 females,ranging 33-82 years,median age 63.9 years) with SPN found by physical examination and diagnosed lung cancer by surgical pathology subsequently were enrolled to this study.Depending on the interval between the date when finding SPN and the date of surgery,these cases were divided into 6 groups,including the group with interval less than 1 month (74 patients),1-3 months (48 patients),3-6 months (10 patients),6-12 months (7 patients),12-24 months (8 patients),and more than 24 months (15 patients).Factors which impact the delay interval between SNP finding and surgery were discussed.The change of tumor' s diameter during observation period,and the pathological characters were also analyzed among each group.Results Of all the delay cases,30.2％ were attributed to doctor,30.9％ attributed to patients themselves,and 38.9％ attributed to hospitals.51.0％ (25/49) of the cases delayed by doctors were misdiagnosed as inflammation,16.3％ (8/49) misdiagnosed as tuberculosis,and 16.3％ (8/49)misdiagnosed as old lesions,which were three common reasons.Patients delayed more than 3 months were more likely to be related to doctor's misdiagnosis than those delayed less than 3 months[70.0％ (28/40) vs.36.8％ (21/57),x2 =10.338.P =0.001].Moreover,the possibility of SPN enlargement was positively correlated with the delay interval.In groups with delay interval more than 24 months or between 12 and 24 months,the percentage of SPN enlargement were 73.3％ (11/15) and 87.5％ (7/8) separately.The proportion of patients with stage IV disease in groups whose delay interval exceeded 12 months (13.3％ for more than 24 months and 12.5％ for 12-24 months) also significantly surpassed others groups with shorter delay interval.Conclusion There exists obvious delayed diagnosis and treatment in lung cancer initially expressed as solitary pulmonary nodules (SPN) during physical examination.Nearly 1/3 patients were delayed by doctors and half of them were misdiagnosed as inflammation.Increase of observation time could result in enlargement of SPN and advancement of disease staging.Thus,patients and doctors should pay more attention and clarify the diagnosis through surgery in less than 3 months after finding SPN,which could remarkably benefit early treatment.
ABSTRACT
Objective To evaluate the long term effect of video-assisted thoracoscopic thymectomy for myasth,enia gravis and the influence of concomitant thymoma.Methods 47 cases of myasthenia gravis were retrospectively reviewed who had received video-assisted thoracoscopic thymectomy from Apr.2001 through Oct.2009.The patients were separated to two groups with or without thymoma.Influence of oncologic factors was carefully studied.Results There were 20 males and 27 females with a mean age of 36.6 yrs.According to the typing system of the Myasthenia Gravis Foundation of America ( MGFA),the patients belonged to type Ⅰ 18 cases,type Ⅱ a 14 cases,type Ⅱ b 14 cases,and Ⅲa 1 case.22 patients were in the group with thymoma,and the other 25 in the group without thymoma.Until the deadline of follow-up time of Jun.2011,only two cases in non-thymomatous group were lost.Follow-up time was 20 to 122 months,mean 57 months.The complete stable remission rate(CSR),pharmacologic remission(PR),minimal manifestations(MM),worse(W),exacerbation(E) and died of myasthenia gravis(D) in non-thymomatous group were 78.3％,13.0％,4.3％,0,0 and 4.3％.In thymomatous group the values were 50.0％,22.7％,13.6％,4.5％,9.1％ and 0.Conclusion Video-assisted thoarcoscopic thymectomy has a satisfactory long term effect for myasthenia gravis.Thymomatous group has no different in overall effectiveness with that of non-thymomatous group although a probably lower complete stable remission rate is prompted.
ABSTRACT
Objective To analysis the clinical radiologic features of intrapulmonary lymph nodes,and to improve the diagnostic rate of intrapulmonary lymph nodes.Methods From May 2008 to September 2011,16 cases of pulmonary nodules were proved pathologically as intrapulmonary lymph nodes,including 9 males and 7 females,with an average age of 58.2 years (39-73 years).All patients accepted chest X-ray and HR CT scan prior to operation,identified of 11 solitary nodules,3 multiple nodules,and other 2 cases of multiple nodules with synchronous ipsilateral lung cancer.We retrospectively review the data as follows:the population and clinical characters,the subjective imaging diagnosis,the imaging characters of the nodule location,size,texture,shape,border,distance from the nearest pleural surface,and the appearance of the surrounding pulmonary parenchyma et al.Results Clinically,six of all the 16 patients are or were cigarette smokers or had an exposure history of inhaled particles,three patients else were all from a same oilfield area although they denied having the Aforementioned history of smoke or exposure.Lung cancer,metastatic tumor,lung cancer intrapulmonary metastasis were the common subjective imaging diagnosis,with a misdiagnosis rate of 56.3％.Radiologically,these intrapulmonary nodules could be seen in the chest X-ray in half of the 16 patients,with a discovery rate of 50％ in chest X- ray screening.The median size of the intrapulmonary lymph nodes was 7.1 mm (4 - 11 mm),all nodules located below the level of the carina,87.5％ ( 14/16 cases) were solid nodules,68.75％ ( 11/16 cases) were round or ovate in shape with a sharp border.87.5％ ( 14/16 cases) were attached to the pleura or within 1 cm from the nearest pleural surface,87.5％ ( 14/16 cases) appeared linear densities extending from the intrapulmonary lymph nodes.The linear denshy referred to the CT imaging feature that a linear soft-tissue density extended from the intrapulmonary lymph nodes,distinct from the normal lung marking like interlobular septa and bronchovascular bundles,with a diameter less than 5 mm; spiculation were detected in only 2 of the 16 patients ; no calcification and mediestinal lymphadenopathy was detect in all the nodules.Pathologically,All nodules contained anthracotic pigment,and follicular hyperplasia were seen in 8 cases.Conclusion Intrapulmonary lymph nodes are rare benign pulmonary nodules possessing certain clinical and radiologic features.Intrapulmonary lymph nodes should be suspected for small subpleural nodules below the level of the carina.
ABSTRACT
Objective To evaluate the feasibility of lobectomy by completely Video-Assisted Thoracoscopic Surgery (cVATS) in the management of bronchiectasis.Methods Between June 2001 and October 2010,a total of 60 major lobectomies were performed in our single center on 32 female and 28 male patients of bronchiectasis,with a mean age of 43.4( range 17 to 69)years.All lobectomies were carried out anatomically and divided into thoracotomy group and cVATS group.Pulmonary vessels and bronchus were dissected by endo-cutters.Conversion to a thoracotomy took place if severe adhesion or bleeding was encountered.Results The operations included 5 lobectomies of right upper lobe,3 of middle lobe,6 of right lowerlobe,3 of left upper lobe,26 of left lower lobe,10 of left lower lobe plus lingular segment,4 of left pneumonectomy,1 of bi-lobectomy,1 of right middle lobe plus wedge resection of lower lobe and 1 of left lower lobe plus right middle lobe.There were 25 patients in the thoracotomy group and 35 patients in the cVATS group,in which 2 operations (5.7％) converted due to severe adhesion,poor differentiation of the fissure and/or the proliferation of tortuous vessels at hilus In thoracotomy and cVATS groups,the operative time were ( 207.6 ± 88.5 ) vs.( 168.7 ± 55.9 ) min ( P =0.041 ),the blood loss were ( 522.0 ±644.2) vs.(210.1 ± 213.1 ) ml ( P =0.009),the mean chest tube duration were ( 5.4 ± 4.4) vs.(6.3 ± 3.4 ) days ( P ＞0.05 ) and the mean length of hospitalization were ( 10.2 ±4.7 ) vs.( 8.5 ± 3.5 ) days ( P ＞ 0.05 ).No mortality or severe complication occurred in both groups.The morbidity was 25.7％ (9/25)vs.17.1％ (6/35) in thoracotomy and cVATS group,with no significant difference statistically (P =0.133 ) . There were 52％ vs.62.9％ patients achieved symptomatic completely relief and significant improvement was obtained in 40.0％ vs.31.4％ patients in thoracotomy and cVATS group separately.Conclusion cVATS lobectomy is safe and effective in the management of bronchiectasis.
ABSTRACT
Objective To evaluate the value of autofluorescence bronchoscope (AFB) in airway examination in central type lung cancer. Methods From Sep 2009 to Mar 2010 ,29 patients ( 23 men , 6 women , median age 62.2 years , range from 34 to 81 years) underwent AFB procedure. There were 3 lesions located at trachea, 1 at right main bronchus, 9 at right upper lobe, 1 at right median bronchus, 1 at right middle lobe, 4 at right lower lobe, 1 at left main bronchus, 9 at left upper lobe.There were 21 preliminary diagnostic cases and 8 postoperative surveillance cases. All procedure was performed under combination of local anaesthesia and general anaesthesia. All patients underwent white light bronchoscopy followed by AFB procedure.All of the suspicious abnormal sites were recorded and biopsied for pathological examination. Results All procedures were safely performed without death or serious complications. 100 specimens were obtained for pathologic examination. Malignant lesion was diagnosed in 39 and non-malignancy in61. All malignant sites were detected by AFB, however WLB missed 12 sites.The sensitivity of AFB and WLB for malignancy were 100% and 69.2%, respectively. In 21 preliminary diagnostic cases,AFB detected all malignancy sites, but WLB missed 23 sites, in which 9 were malignant sites. In 8 rechecked patients, AFB detected all malignancy sites, but WLB missed 7 sites, in which 3 were malignant sites. Conclusion Autofluorescence bronchoscopy could be more accurate in judging the extent of the tumor invasion, more sensitive in finding multiple lesions in airway, more sensitive in detecting early cancer recurrence in postoperative surveillance patients.

ABSTRACT
Objective To optimize operative techniques of completely video-assisted thoracoscopic lobectomy by reviewing the experience of Peking University People's Hospital. Methods From September 2006 to August 2010, 408 patients (214 males,194 females) with median age of 58.6 years (range from 15 to 86 years) underwent completely thoracoscopic lobectomy. All procedures were conducted under general anesthesia with double lumen intubation. The thoracoscope was introduced through 7th or 8th intercostals space on the mid-axillaries line. The 4 cm long utility incision was made on the 4th or 5th intercostals space anterior axillary's line without rib-spreading. A third retraction incision located on the 7th or 8th intercostals space sub-scapular line. The surgeon stands on the ventral side of patient using an electrocautery hook and a suction device through the utility incision. Anatomic lobectomy was performed with systemic mediastinal lymph node dissection for lung cancer patients. Results All procedures were carried out smoothly with no case of serious complication. There was 1 case death because of respiratory failure of pulmonary fungal infection during the operative period. The average surgical duration was 195 minutes, and average blood loss was 249 ml with no blood transfusion required. There were 35 cases (8.6%) of conversion to open thoracotomy, including interference by lymph nodes, bleeding, inflammatory adhesion of Artery and large size tumors.The results of pathology show 322 cases of malignant disease and 86 cases of benign disease. Conclusion To grasp the core technique of completely thoracoscopic lobotomy may make the procedure undergone smoothly, and may shorten the learning curve.
ABSTRACT
<p><b>BACKGROUND AND OBJECTIVE</b>Solitary pulmonary nodules (SPN) is a knotty problem in clinical work. The clinical manifestation and pathological features of SPN in sizes may be obviously different. The aim of this study is to analyze the relationship between the diameters and clinicopathologic characteristics of SPN.</p><p><b>METHODS</b>390 patients (212 male, 178 female, ranging from 17 years to 86 years, median age 57.1 years) with SPN who were postoperatively diagnosed by pathology between Jan. 2000 and Jun. 2009 are enrolled to this study. In these cases, the number of SPN diameters which are smaller than 0.5 cm (including 0.5 cm) (group A) is 16, between 0.5 cm and 1 cm (including 1 cm, not including 0.5 cm) (group B) is 58, between 1 cm and 2 cm (group C) is 163, and between 2 cm and 3 cm (group D) is 153. The clinical manifestation, and postoperative pathological characters are analyzed in various diameter ranges.</p><p><b>RESULTS</b>All procedures were carried out securely, including tumor enucleation (n = 20), wedge resection (n = 153), lobectomy (n = 217). There are 130 benign cases (33.3%) and 260 malignant cases (66.7%). 58.5% SPN are detected incidently with no symptoms. There is an increasing incidence of clinical symptoms as the increasing diameter of SPN. All the cases are divided into 4 groups, the prevalence of malignant are separated 43.7% (group A), 50.0% (group B), 63.2% (group C), 79.1% (group D). The diameter of SPN is positively correlated with incidence of malignancy (chi2 = 22.535, P < 0.001). Single factor analysis and Logistic regression analysis show the diameter of SPN is an independent risk factor of malignant pathology (OR = 1.922, P < 0.001). Fourteen patients in all of the SPN were followed up by 2 years or more before operation, and 10 of them turn out to be malignant at last. In the 14 patients, 7 cases were found not enlarged by CT scan, and 3 of them (42.9%) were malignant.</p><p><b>CONCLUSION</b>The diameter of SPN is highly associated with clinical symptoms, and is a significant risk factor to predict pathology. Early diagnosis and treatment is so important for patients with SPN.</p>
