Whether this is appropriate for minimally invasive approach is not yet clear. We evalu- ated the feasibility of complete video-assisted thoracoscopic surgery （VATS） thymectomy for the treatment of Ma- saoka stage I and Ⅱ thymoma-associated myasthenia gravis, compared to conventional trans-sternal thymectomy. We summarized 33 patients with Masaoka stage I and II thymoma-associated myasthenia gravis between April 2006 and September 2011. Of these, 15 patients underwent right-sided complete VATS （the VATS group） by us- ing adjuvant pneuomomediastinum, comparing with 18 patients using the trans-sternal approach （the T3b group）. No intraoperative death was found and no VATS case required conversion to median sternotomy. Significant differences between the two groups regarding duration of surgery and volume of intraoperative blood loss （P = 0.001 and P 〈 0.001, respectively） were observed. Postoperative morbidities were 26.7% and 33.3% for the VATS and T3b groups, respectively. All 33 patients were followed up for 12 to 61 months in the study. The cumulative probabilities of reaching complete stable remission and effective rate were 26.7% （4/15） and 93.3% （14/15） in the VATS group, which had a significantly higher complete stable remission and effective rate than those in the T3b group （P = 0.026 and P = 0.000, respectively）. We conclude that VATS thymectomy utilizing adjuvant pneuomo- mediastinum for the treatment of stage I and II thymoma-associated myasthenia gravis is technically feasible but deserves further investigation in a large series with long-term follow-up.展开更多

Methods： From November 2011 to June 2013, 32 consecutive patients with PSP were treated by nonintubated uniportal thoracoscopic bullectomy using epidnral anaesthesia and sedation without endotracheal intubation. An incision 2 cm in length was made at the 6th intercostal space in the median axillary line. The pleural space was entered by blunt dissection for placement of a soft incision protector. Instruments were then inserted through the incision protector to perform thoracoscopic bullectomy. Data were collected within a minimum follow-up period of 10 months. Results： The average time of surgery was 49.0 rain （range, 33-65 rain）. No complications were recorded. The postoperative feeding time was 6 h. The mean postoperative chest tube drainage and hospital stay were 19.3 h and 41.6 h, respectively. The postoperative pain was mild for 30 patients （93.75%） and moderate for two patients （6.25%）. No recurrences ofpneumothorax were observed at follow-up. Conclusions： The initial results indicated that nonintubated uniportal video-assisted thoracoscopic operations are not only technically feasible, but may also be a safe and less invasive alternative for select patients in the management of PSP. This is the first report to include the use of a nonintubated uniportal technique in VATS for such a large number of PSP cases. Further work and development of instruments are needed to define the applications and advantages of this technique.展开更多

Materials and methods： Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results： Twelve males and one female, with age ranging from 15 to 36 years （mean 23.1 years）, were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously （n=4） or sequentially （n=9）. The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients （84.6%） had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was （45.6±18.3） min （range 25-96 min） and （120.6±28.7） min （range 84-166 min） respectively for the non-simultaneous （second VATS for the recurrence of contralateral side after first VATS） and simultaneous （bilateral VATS in one operation） procedures. There was no postoperative mortality. However, prolonged air leakage （〉7 d） occurred in one patient （7.7%） who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions： VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.展开更多

Methods： A total of 51 patients with radiologically or mediastinoscopically confirmed stage ⅢA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/ complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher. Results： A total of 51 patients with non-small cell lung cancer （NSCLC） were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41 （80.4%） had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50 （98%） received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage （〉1,000 mL）, and the postoperative recovery was satisfactory. Up to 45 patients （88.2%） did not suffer from any perioperative complication, and 6 （11.8%） experienced one or more complications. Conclusions： VATS radical treatment is a safe and feasible treatment for stage ⅢA lung cancer.展开更多

In the United States, it causes more cancer-related deaths than the next four causes （breast cancer, prostate cancer, colon cancer, and pancreatic cancer） of cancer-related mortality combined （1）. About 30% of people have already progressed to stage III lung cancer and 40% to stage IV at the time they are diagnosed （2）. Although chest X-ray and sputum cytology, when applied in health check-ups, can identify some relatively small tumors, they are not able to lower the overall mortality （3）. More recently,展开更多

However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival. Methods： Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival. Results： Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients （69%）. The median 5-year overall survival for Stage Ⅰ, Ⅱ, Ⅲ and Ⅳ disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis. Conclusions： VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectableNSCLC展开更多

Methods： From 1995 to 2006, seven patients （two males, five females）, with ages ranging from 26 to 58 years, were impressed with Stage 1 sarcoidosis （mediastinal or hilar lymph nodes involvements without lung involvement） by histological examination of intrathoracic lymph nodes （LNs） and/or lung parenchyma taken＇from VATS biopsy. Three of them received PET or PET-CT evaluation. VATS was approached from the right and left side in one and six patients, respectively, according to the locations of their lesions. Results： All the VATS biopsied LNs or lung specimens were adequate for establishing diagnosis. Mediastinal LNs were taken from Groups 3, 4 in four, Group 7 in two, and Groups 5, 6 in one of them. Hilar LNs biopsies were performed in four cases. Lung biopsy was performed in all but two cases. All of them were expressed pathologically or radiologically as Stage 1 sarcoidosis. PET-CT revealed high emission signals over these affected LNs. These patients received oral steroid treatment or follow up only. All of them were followed up from 5 months to 11 years with satisfactory results. Conclusion： VATS biopsy is a minimally invasive, safe and effective procedure. It can be used as a diagnostic altermative of transbronchial lung biopsy （TBLB）, and can harvest larger and more areas of specimens than mediastinoscopy for staging patients with sarcoidosis. PET-CT can provide us more accurate information about the characteristics and localization of these lesions before biopsy. VATS combined with PET-CT can provide more accurate and earlier diagnosis of patients with unknown intrathoracic lesions, including the sarcoidosis.展开更多

Treatment of hepatic hydrothorax remains a challenge at present. Methods： Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery （VATS） Repair of the diaphragmatic defects, or pleurodesis by focal pleurectomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged （〉7 d） high-output （〉300 ml/d） pleural effusion. Results： Out of the 12 patients, 8 （67%） had uneventful postoperative course and did not require tube for drainage more than 3 months after discharge. In 4 （33%） patients the pleural effusion still recurred after discharge due to end-stage cirrhosis with massive ascites. Conclusion： We conclude that the repair of the diaphragmatic defect and pleurodesis through VATS could be an alternative of transjugular intrahepatic portal systemic shunt （T1PS） or a bridge to liver transplantation for patients with refractory hepatic hydrothorax. Pleurodesis with electrocauterization can be an alternative therapy if talc is unavailable.展开更多

文摘BACKGROUND Esophageal cancer is sixth leading cause of cancer deaths and the eighth most common cancer worldwide.In the recent times,the incidence and mortality rates have increased.To improve the survival in esophageal carcinoma,newer tactics have to be applied to improve outcomes.It is well established that in cases of carcinoma lung and stomach,presence of micrometastasis or spread of tumor cell following surgical manipulation has been shown to predict recurrence and poor prognosis.Similarly,spread of tumor cell during esophagectomy or presence of occult micrometastatic disease in esophageal carcinoma may lead to early tumor recurrence and poor prognosis.The actual incidence of pleural micrometastasis and tumor spillage following thoracoscopic esophagectomy is not clear.The presence of malignant cells in cytologic or immunocytochemical analysis may help in prognostication and further therapeutic decision making.AIM To assess the incidence of micrometastasis and tumor spillage among the patients undergoing thoracoscopic surgery for esophageal carcinoma.METHODS An observational study was done at Department of Surgical Gastroenterology,Jawaharlal Institute of Postgraduate Medical Education and Research,Puducherry.Nineteen patients aged 18 to 70 years with slight male preponderance,undergoing elective thoracoscopic esophagectomy for esophageal carcinoma were included in this observational study from June 2021 to June 2023.Pre and post dissection pleural cavity lavage was done with 200 mL saline and the fluid was subjected to cytologic and immunocytological examination.The cytology and immunocytological examination report was interpreted as positive for malignant cells or negative for malignant cells.Immunocytological examination was done and evaluated for presence or absence of tumor markers cytokeratin 7 and p40 signifying presence or absence of tumor spillage.RESULTS Rate of pre dissection fluid was negative for the malignant cell by cytological and immunocytological analysis in all cases indicating no micrometastasis in our group of patients.Rate of post dissection fluid was negative for the malignant cell by cytological and immunocytological analysis in all cases indicating no incidence of tumor spillage post-surgery in our patients.No significant association was found between age,gender,body mass index,site of lesion,histological type,neoadjuvant therapy and tumor-nodes-metastasis staging with pre and post dissection pleural fluid cytological and immunohistochemical analysis in our study.CONCLUSION This study assessed the incidence of micrometastasis and tumor spillage following minimal invasive esophagectomy could not find any tumor cells in both pre and post dissection samples.

文摘BACKGROUND Although thoracotomy has been the conventional treatment for patients with early esophageal cancer(EEC),its drawbacks underscore the demand for more effective therapeutic strategies to improve surgical outcomes.AIM To comprehensively analyze the effect of totally thoracoscopic esophagectomy(TTE)on postoperative complications and serum inflammatory factors in patients diagnosed with EEC.METHODS A total of 113 patients with EEC,who were admitted to our hospital between September 2022 and December 2024,were recruited for this study.Specifically,55 patients were assigned to the control group and underwent conventional surgical procedures,whereas 58 patients formed the research group and underwent TTE.Subsequently,a series of comparisons and analyses were conducted between the two groups.These comparisons included surgery-related parameters,such as incision length,operation duration,and the number and extent of lymph node dissection;postoperative complications,namely,empyema,pulmonary infection,incision infection,anastomotic fistula,and delayed gastric emptying;postoperative pain,which was quantitatively evaluated by the Numerical Rating Scale;postoperative hospitalization duration;serum inflammatory factors,including interleukin(IL)-6,IL-8,and tumor necrosis factor-α;and stress response-associated indicators,such as C-reactive protein,cortisol,and adrenaline.RESULTS Statistical data demonstrated that compared with the control group,the research group exhibited substantially shorter incision length and postoperative hospitalization duration.The two groups had comparable number and extent of lymph node dissection.Notably,both the overall incidence of postoperative complications and the Numerical Rating Scale score on postoperative day 3 were remarkably lower in the research group.Although the levels of IL-6,IL-8,tumor necrosis factor-α,C-reactive protein,cortisol,and adrenaline in the research group increased statistically postoperatively,they were still considerably lower than those in the control group.CONCLUSION In patients with EEC,TTE not only reduces the risk of postoperative complications but also effectively alleviates the body’s inflammatory and stress responses associated with surgery.

文摘Background:Totally thoracoscopic surgery(TTS)and right lateral thoracotomy(RLT)are both extensively utilized in the surgical repair for atrial septal defect(ASD).However,RLT is generally considered in low-weight pediatric patients as a result of restricted surgical exposure.This study aims to introduce an RLT approach for ASD repair in adults and compare its clinical outcomes with TTS.Methods:We conducted a retrospective analysis of the clinical data of 23 adult patients who underwent ASD repair at Guangdong Provincial People’s Hospital between June and October 2024.Patients were divided into two groups based on the surgical approach they adopted:group totally thoracoscopic surgery(TTS,n=12)and group right lateral thoracotomy(RLT,n=11).All individuals finished a follow-up three months after surgery.Operative parameters,postoperative courses,echocardiographic measurements and laboratory investigations were compared between the two groups.Results:The total surgical duration was significantly longer in group RLT compared with group TTS[(234.00±47.93)min vs.(175.17±52.36)min,p=0.011].Group RLT exhibited a significantly higher respiratory index(RI)at<6 h postoperatively(1.00±0.58 vs.0.30±0.37,p=0.01)and significantly lower levels of soluble suppression of tumorigenicity 2(sST2)[(136.61±43.12)ng/mL vs.(199.08±33.56)ng/mL,p=0.037]and cardiac troponin(cTnT)[(277.04±89.85)pg/mL vs.(343.30±482.40)pg/mL,p=0.047]at 12-24 h postoperatively.Echocardiographic measurements showed no significant differences between two groups,except for a more pronounced reduction in left atrial(LA)size at discharge in group TTS[(5.00±3.64)mm vs.(0.09±4.44)mm,p=0.008].Conversely,group RLT demonstrated a less significant decrease in glutamyl transpeptidase(GGT)[(1.00±6.00)U/L vs.(5.25±3.86)U/L,p=0.026]but a more significant decrease in blood urea nitrogen(BUN)[(1.81±1.10)mg/dL vs.(0.81±1.07)mg/dL,p=0.038].Conclusions:RLT for ASD repair in adults demonstrated comparable clinical outcomes to TTS in terms of postoperative recovery and cardiac function and also produced fewer scars than TTS.Our study proved the feasibility,safety and cosmetic effects of uniport RLT for ASD repair in adults when compared with TTS.
文摘Complete resection could be achieved in virtually all myasthenic patients with Masaoka stage I and II thymoma us- ing the trans-sternal technique. Whether this is appropriate for minimally invasive approach is not yet clear. We evalu- ated the feasibility of complete video-assisted thoracoscopic surgery （VATS） thymectomy for the treatment of Ma- saoka stage I and Ⅱ thymoma-associated myasthenia gravis, compared to conventional trans-sternal thymectomy. We summarized 33 patients with Masaoka stage I and II thymoma-associated myasthenia gravis between April 2006 and September 2011. Of these, 15 patients underwent right-sided complete VATS （the VATS group） by us- ing adjuvant pneuomomediastinum, comparing with 18 patients using the trans-sternal approach （the T3b group）. No intraoperative death was found and no VATS case required conversion to median sternotomy. Significant differences between the two groups regarding duration of surgery and volume of intraoperative blood loss （P = 0.001 and P 〈 0.001, respectively） were observed. Postoperative morbidities were 26.7% and 33.3% for the VATS and T3b groups, respectively. All 33 patients were followed up for 12 to 61 months in the study. The cumulative probabilities of reaching complete stable remission and effective rate were 26.7% （4/15） and 93.3% （14/15） in the VATS group, which had a significantly higher complete stable remission and effective rate than those in the T3b group （P = 0.026 and P = 0.000, respectively）. We conclude that VATS thymectomy utilizing adjuvant pneuomo- mediastinum for the treatment of stage I and II thymoma-associated myasthenia gravis is technically feasible but deserves further investigation in a large series with long-term follow-up.
文摘Objective： The objective of the current study was to evaluate the feasibility and safety of nonintubated nniportal video-assisted thoracoscopic surgery （VATS） for the management of primary spontaneous pneumothorax （PSP）. Methods： From November 2011 to June 2013, 32 consecutive patients with PSP were treated by nonintubated uniportal thoracoscopic bullectomy using epidnral anaesthesia and sedation without endotracheal intubation. An incision 2 cm in length was made at the 6th intercostal space in the median axillary line. The pleural space was entered by blunt dissection for placement of a soft incision protector. Instruments were then inserted through the incision protector to perform thoracoscopic bullectomy. Data were collected within a minimum follow-up period of 10 months. Results： The average time of surgery was 49.0 rain （range, 33-65 rain）. No complications were recorded. The postoperative feeding time was 6 h. The mean postoperative chest tube drainage and hospital stay were 19.3 h and 41.6 h, respectively. The postoperative pain was mild for 30 patients （93.75%） and moderate for two patients （6.25%）. No recurrences ofpneumothorax were observed at follow-up. Conclusions： The initial results indicated that nonintubated uniportal video-assisted thoracoscopic operations are not only technically feasible, but may also be a safe and less invasive alternative for select patients in the management of PSP. This is the first report to include the use of a nonintubated uniportal technique in VATS for such a large number of PSP cases. Further work and development of instruments are needed to define the applications and advantages of this technique.
文摘Objective： To review our experience of the treatment of bilateral primary spontaneous pneumothorax （PSP） by video-assisted thoracoscopic surgery （VATS）. Materials and methods： Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results： Twelve males and one female, with age ranging from 15 to 36 years （mean 23.1 years）, were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously （n=4） or sequentially （n=9）. The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients （84.6%） had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was （45.6±18.3） min （range 25-96 min） and （120.6±28.7） min （range 84-166 min） respectively for the non-simultaneous （second VATS for the recurrence of contralateral side after first VATS） and simultaneous （bilateral VATS in one operation） procedures. There was no postoperative mortality. However, prolonged air leakage （〉7 d） occurred in one patient （7.7%） who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions： VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.
文摘Tuberculoma of the lung is one of manifestations in tuberculosis and usually presents as a solitary pulmonary nodule(SPN).It is difficult to differentiate tuberculoma from SPN by other benign or malignant diseases.At present,the crucial role of video-assisted thoracoscopic surgery(VATS) in diagnosis and treatment of pulmonary diseases has been well acknowledged.Here,we reported 53 patients undergoing VATS resection for tuberculomas in our series.No postoperative mortality was found and only two patients experienced prolonged air-leakage(>7 d) and two had minor wound infections that were recovered after anti-tuber-culosis or antibiotic treatment.Anti-tuberculosis chemotherapy from 6 to 12 months was routinely used postoperatively.We conclude that VATS is a satisfactory tool for the diagnosis and treatment of tuberculoma and can also establish a reliable diagnosis for all patients with SPNs.
文摘Objective： The current study was prospectively designed to explore the application of video-assisted thoracoscopic surgery （VATS） radical treatment for patients with stage ⅢA lung cancer, with the primary endpoints being the safety and feasibility of this operation and the second endpoints being the survival and complications after the surgery. Methods： A total of 51 patients with radiologically or mediastinoscopically confirmed stage ⅢA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/ complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher. Results： A total of 51 patients with non-small cell lung cancer （NSCLC） were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41 （80.4%） had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50 （98%） received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage （〉1,000 mL）, and the postoperative recovery was satisfactory. Up to 45 patients （88.2%） did not suffer from any perioperative complication, and 6 （11.8%） experienced one or more complications. Conclusions： VATS radical treatment is a safe and feasible treatment for stage ⅢA lung cancer.
文摘Thoracic Surgery is a continuous evolving specialty. In the past, thoracic surgeons had to make large incisions in order to operate any pathology inside the chest. This often meant big, painful and ugly scars and long recovery times after surgery. But he history of thoracic surgery changed since the begining of video-assisted thoracoscoDic surgery （VATg3
文摘Lung cancer is the most common cancer worldwide. In the United States, it causes more cancer-related deaths than the next four causes （breast cancer, prostate cancer, colon cancer, and pancreatic cancer） of cancer-related mortality combined （1）. About 30% of people have already progressed to stage III lung cancer and 40% to stage IV at the time they are diagnosed （2）. Although chest X-ray and sputum cytology, when applied in health check-ups, can identify some relatively small tumors, they are not able to lower the overall mortality （3）. More recently,
文摘This study sought to report our 6-year experience with the LigaSure vessel sealing system（LVSS） in videoassisted thoracoscopic surgery（VATS） for primary spontaneous pneumothorax.A series of 180 consecutive patients with primary spontaneous pneumothorax were operated on in our institution from May 2005 to December 2010.Intraoperatively,large lesions（bullae or blebs） with a diameter more than 2 cm were resected by staplers,and the residual lesions were treated by LVSS.LVSS was also used to ablate the apical area when no lesions were found.Conventional apical pleural abrasion was done in all cases.All patients were successfully treated using VATS with minimal perioperative bleeding.The mean operating time was 76 minutes（range,43-160 minutes） for single-side procedures and 169 minutes（range,135-195 minutes） for bilateral procedures,the mean number of applied staples was 1.93 per patient（range,0-8 days）,the duration of drainage was 3.8 days（range,2-15 days）,and the duration of hospital stay was 5.8 days（range,3-16 days）.Postoperative complications included persistent air leak（〉 5 days） in 11 cases（6.1%） and residual pneumothorax in 6（3.3%）.None required reoperation.The mean duration of follow-up was 57 months（range,24-105 months）.Recurrence was seen in three cases（1.7%）,and all underwent another operation thereafter.None of the lesions in the relapse cases received ablation with LVSS in the first operation.LVSS can optimize VATS for primary spontaneous pneumothorax and reduces the use of single-use staples.The method is safe,easy to use,and cost-effective and produces satisfactory results.
文摘BACKGROUND In esophageal squamous carcinoma,lymphadenectomy along the left recurrent laryngeal nerve(RLN)is recommended owing to its highly metastatic potential.However,this procedure is difficult due to limited working space in the left upper mediastinum,and increases postoperative complications.AIM To present a novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position.METHODS The fundamental concept of this novel method is to exfoliate a bilateral pedicled nerve flap,which is a two-dimensional membrane,which includes the left RLN,lymph nodes(LNs)along the left RLN,and tracheoesophageal vessels,by suspending the esophagus to the dorsal side and pushing the trachea to the ventral side(named“bilateral exposure method”).Then,the hollow-out method is performed to transform the two-dimensional membrane to a three-dimensional structure,in which the left RLN and tracheoesophageal vessels are easily distinguished and preserved during lymphadenectomy along the left RLN.This novel method was retrospectively evaluated in 116 consecutive patients with esophageal squamous carcinoma from August 2016 to February 2018.RESULTS There were 58 patients in each group.No significant difference was found between the two groups in terms of age,gender,postoperative pneumonia,anastomotic fistula,and postoperative hospitalization.However,the number of dissected LNs along the left RLN in this novel method was significantly higher than that in the conventional method(4.17±0.359 vs 2.93±0.463,P=0.0447).Moreover,the operative time and the rate of postoperative hoarseness in the novel method were significantly lower than those in the conventional method(306.0±6.774 vs 335.2±7.750,P=0.0054;4/58 vs 12/58,P=0.0312).CONCLUSION This novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position is much safer and more effective.
文摘Background： Video-assisted thoracic surgery （VATS） has been shown to be a safe alternative to conventional thoracotomy for patients with non-small cell lung cancer （NSCLC）. However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival. Methods： Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival. Results： Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients （69%）. The median 5-year overall survival for Stage Ⅰ, Ⅱ, Ⅲ and Ⅳ disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis. Conclusions： VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectableNSCLC
文摘Background： The purpose of this study was to describe our experiences and analyze the benefits of video-assisted thoracoscopic surgery （VATS） combined with positron emitted tomography （PET）-computed tomography （CT） in the diagnosis of patients with early （Stage 1） sarcoidosis. Methods： From 1995 to 2006, seven patients （two males, five females）, with ages ranging from 26 to 58 years, were impressed with Stage 1 sarcoidosis （mediastinal or hilar lymph nodes involvements without lung involvement） by histological examination of intrathoracic lymph nodes （LNs） and/or lung parenchyma taken＇from VATS biopsy. Three of them received PET or PET-CT evaluation. VATS was approached from the right and left side in one and six patients, respectively, according to the locations of their lesions. Results： All the VATS biopsied LNs or lung specimens were adequate for establishing diagnosis. Mediastinal LNs were taken from Groups 3, 4 in four, Group 7 in two, and Groups 5, 6 in one of them. Hilar LNs biopsies were performed in four cases. Lung biopsy was performed in all but two cases. All of them were expressed pathologically or radiologically as Stage 1 sarcoidosis. PET-CT revealed high emission signals over these affected LNs. These patients received oral steroid treatment or follow up only. All of them were followed up from 5 months to 11 years with satisfactory results. Conclusion： VATS biopsy is a minimally invasive, safe and effective procedure. It can be used as a diagnostic altermative of transbronchial lung biopsy （TBLB）, and can harvest larger and more areas of specimens than mediastinoscopy for staging patients with sarcoidosis. PET-CT can provide us more accurate information about the characteristics and localization of these lesions before biopsy. VATS combined with PET-CT can provide more accurate and earlier diagnosis of patients with unknown intrathoracic lesions, including the sarcoidosis.

文摘BACKGROUND Pleural effusions occur for various reasons,and their diagnosis remains challenging despite the availability of different diagnostic modalities.Medical thoracoscopy(MT)can be used for both diagnostic and therapeutic purposes,especially in patients with undiagnosed pleural effusion.AIM To assess the diagnostic efficacy and safety of MT in patients with pleural effusion of different causes.METHODS Between January 1,2012 and April 30,2021,patients with pleural effusion underwent MT in the Department of Respiratory Medicine,The Second Affiliated Hospital of Xi’an Jiaotong University(Shaanxi,China).According to the discharge diagnosis,patients were divided into malignant pleural effusion(MPE),tuberculous pleural effusion(TBPE),and inflammatory pleural effusion(IPE)groups.General information,and tuberculosis-and effusion-related indices of the three groups were analyzed.The diagnostic yield,diagnostic accuracy,performance under thoracoscopy,and complications of patients were compared among the three groups.Then,the significant predictive factors for diagnosis between the MPE and TBPE groups were analyzed.RESULTS Of the 106 patients enrolled in this 10-year study,67 were male and 39 female,with mean age of 57.1±14.184 years.Among the 74 thoracoscopy-confirmed patients,41(38.7%)had MPE,21 had(19.8%)TBPE,and 32(30.2%)were undiagnosed.Overall diagnostic yield of MT was 69.8%(MPE:75.9%,TBPE:48.8%,and IPE:75.0%,with diagnostic accuracies of 100%,87.5%,and 75.0%,respectively).Under thoracoscopy,single or multiple pleural nodules were observed in 81.1%and pleural adhesions in 34.0%with pleural effusions.The most common complication was chest pain(41.5%),followed by chest tightness(11.3%)and fever(10.4%).Multivariate logistic regression analyses showed effusion appearance[odds ratio(OR):0.001,95%CI:0.000-0.204;P=0.010]and carcinoembryonic antigen(OR:0.243,95%CI:0.081-0.728;P=0.011)as significant for differentiating MPE and TBPE,with area under the receiver operating characteristic curve of 0.977(95%CI:0.953-1.000;P<0.001).CONCLUSION MT is an effective,safe,and minimally invasive procedure with high diagnostic yield for pleural effusion of different causes.

文摘BACKGROUND Situs inversus totalis(SIT)is a rare congenital condition that is characterized by a complete mirror image of the typical arrangement of the thoracic and abdominal viscera.Performing thoracoscopic segmentectomy for a patient with lung cancer and SIT is an extremely skilled and challenging surgical procedure.CASE SUMMARY A 41-year old woman with a medical history of dextrocardia since childhood was admitted to our hospital with a mixed ground-glass opacity(mGGO)in her left lung field,discovered by computed tomography during her health checkup.In order to facilitate surgical orientation,three-dimensional computed tomography bronchography and angiography(3D-CTBA)was preoperatively carried out.The result of 3D-CTBA was consistent with the diagnosis of SIT and an mGGO in the posterior segment of the left upper lobe(LS2).Surgery was conducted in accordance with preoperative 3D-CTBA and designed surgical procedure,combined with intraoperative navigation.Final pathological examination revealed in situ adenocarcinoma.The patient’s postoperative condition was uneventful and no complications were observed.CONCLUSION We present the first case of lung cancer in a patient with SIT who successfully underwent thoracoscopic segmentectomy assisted by 3D-CTBA.This is a new technique that covers precise confirmation and dissection of targeted structures and intersegmental demarcation,and can help achieve a meticulous anatomical segmentectomy.
文摘Background： Hepatic hydrothorax is defined as a significant pleural effusion in patients with liver cirrhosis and without underlying cardiopulmonary diseases. Treatment of hepatic hydrothorax remains a challenge at present. Methods： Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery （VATS） Repair of the diaphragmatic defects, or pleurodesis by focal pleurectomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged （〉7 d） high-output （〉300 ml/d） pleural effusion. Results： Out of the 12 patients, 8 （67%） had uneventful postoperative course and did not require tube for drainage more than 3 months after discharge. In 4 （33%） patients the pleural effusion still recurred after discharge due to end-stage cirrhosis with massive ascites. Conclusion： We conclude that the repair of the diaphragmatic defect and pleurodesis through VATS could be an alternative of transjugular intrahepatic portal systemic shunt （T1PS） or a bridge to liver transplantation for patients with refractory hepatic hydrothorax. Pleurodesis with electrocauterization can be an alternative therapy if talc is unavailable.
文摘Thoracoscopic surgeries usually require single-lung ventilation under general anesthesia because of the need to obtain a sufficient working space.In patients with impaired pulmonary function,if the patient can undergo general anesthesia,a more selected collapse of the lung is considered to be beneficial for intraoperative oxygenation.The selective bronchial blockade of the lobe to be resected has been reported by several investigators （1-3）.Mukaida and coworkers first reported thoracoscopic surgery for pnenmothorax under local and epidural anesthesia in 1998 in high-risk patients contraindicated for general anesthesia （4）.
