Middle lobe torsion occurred after right upper and lower lobectomy in a 74-year-old man. Immediate re-exploratory thoracotomy using the 3-cm uniportal VATS approach was performed. The torsion was corrected, and the lobe was anchored to the anterior chest wall with Prolene stitches. The patient recovered well postoperatively with daily improvements in chest radiographic findings. Follow-up examination was performed using fiberbronchoscopy, which revealed an unobstructed right middle lobe bronchus and sticky yellow sputum. Follow-up chest computed tomography was performed 3 months after the primary surgery and revealed increased expansion of the right middle lobe. We repositioned the right middle lobe successfully by using the 3-cm uniportal VATS approach, but more cases are needed to confirm the feasibility of the approach. Lobectomy remains the primary treatment option for such cases.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

We were interested in introducing pulmonary vessel blocking techniques in open thoracic surgery into video-assisted thoracic surgery （VATS） procedures. In this study, we reported a surgical technique simultaneously blocking the pulmonary artery and the pulmonary vein for partial removal of the pulmonary artery under VATS. Seven patients with non-small-cell lung cancer （NSCLC） received lobectomy with partial removal of the pulmonary artery using the technique between December 2007 and March 2012. Briefly, rather than using a small clamp on the distal pulmonary artery to the area of invading cancer, we replaced a vascular clamp with a ribbon and Hem-o-lock clip to block the preserved pulmonary veins so as to prevent back bleeding and yield a better view for surgeons. The mean occlusion time of the pulmonary artery and pulmonary veins were 44.0±10.0 and 41.3±9.7 minutes, respectively. The mean repair time of the pulmonary artery was 25.3±13.7 minutes. No complications occurred. No patients showed abnormal blood flow through the reconstructed vessel. There were no local recurrences on the pulmonary artery. In conclusion, the technique for blocking the pulmonary artery and veins is feasible and safe in VATS and reduces the risk of abrupt intraoperative bleeding and the chance of converting to open thoracotomy, and extends the indications of VATS lobectomy.展开更多

Case: A 2-year-old girl with congenital cystic adenomatoid malformation of the right middle lobe (RML) was referred to our institution for further management after a series of infections. The vein of the RML, which drains into the superior pulmonary vein, was isolated and divided using endoclips. The bronchus was then exposed and divided using endo-clips. The arteries of the RML could be identified and ligated, allowing a line demarcating the major fissure to be identified and dissected. A stapler device was then used to seal the lung parenchyma and create a division between the right upper and middle lobes. She is currently well after follow-up of 16 months, with no episodes of respiratory distress or recurrence of symptoms. Conclusion: Our technique for dividing the pulmonary vein, then the bronchus, then the pulmonary artery and finally the fused fissure is safe and could be applied whenever fused fissures are encountered during thoracoscopic pulmonary lobectomy.展开更多

The aim of this study was to compare the perioperative outcomes of uniportal and triportal thoracoscopic Iobectomy and sublobectomy for early-stage NSCLC. Methods： A total of 405 patients with lung lesions underwent thoracoscopic lobectomy or sublobectomy through a uniportal or triportal procedure in approximately 7-month period （From November 2014 to May 2015）. A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes of patients who received uniportal or triportal thoracoscopic lobectomy and sublobectomy. Results： Fifty-eight patients underwent uniportal and 347 patients underwent triportal pulmonary resection. The conversion rate for uniportal and triportal procedure was 3.4% （2/58） and 2.3% （8/347）, respectively. The complication rate for uniportal and triportal procedure was 10.3% and 9.5%, respectively. There was no perioperative death in either group. Most patients had early-stage NSCLC in both groups （uniportal： 45/47, 96%; triportal： 313/343, 91%）. Propensity score-matching analysis demonstrated no significant differences in operation time, intraoperative blood loss, numbers of dissected lymph nodes, number of stations of lymph node dissected, duration of chest tube, and complication rate between uniportal and triportal group for early-stage NSCLC. However, the duration of postoperative hospitalization was longer in the uniportal group （6.83 ± 4.17 vs. 5.42 ± 1.86 d, P = 0.036） compared with the triportal group. Conclusions： Uniportal thoracoscopic lobectomy and sublobectomy is safe and feasible, with comparable short-term outcomes with triportal thoracoscopic pulmonary resection. Uniportal lobectomy and sublobectomy lead to similar cure rate as triportal Iobectomy and sublobectomy for early NSCLC.展开更多

By retrospectively comparing the outcomes from the Iobectomies that used thoracotomy vs. cVATS, we determined the appropriateness of the minimally invasive cVATS approach in the management of bronchiectasis. Methods Between June 2001 and October 2010, 60 patients with bronchiectasis underwent surgery, of which 56 Iobectomies were performed. All Iobectomies were carried out by either thoracotomy or cVATS approach. Pulmonary vessels and bronchi were manipulated by ligation or stapler in the thoracotomy group, while they were dissected by endo-cutters in the cVATS group. Results There were 21 patients in the thoracotomy group and 35 patients in the cVATS group. Two cVATS patients （5.7%） converted. The difference in operation time, chest tube duration, lengths of hospitalization, and morbidity were not significantly different between the two groups （P 〉0.05）. The blood loss was less in the cVATS group （P=0.015）. A total of 52.4% and 62.9% of patients were postoperatively asymptomatic in the thoracotomy and cVATS groups respectively, and symptomatic improvement was obtained in 38.1% patients by thoracotomy vs. 31.4% patients by cVATS. Conclusion cVATS Iobectomy is safe and effective for the management of bronchiectasis, especially for the patients with localized lesions.展开更多

文摘We aimed to describe a method for repositioning of right middle lobar torsion by using a 3-cm uniportal video-assisted thoracoscopic surgery(VATS) approach. Middle lobe torsion occurred after right upper and lower lobectomy in a 74-year-old man. Immediate re-exploratory thoracotomy using the 3-cm uniportal VATS approach was performed. The torsion was corrected, and the lobe was anchored to the anterior chest wall with Prolene stitches. The patient recovered well postoperatively with daily improvements in chest radiographic findings. Follow-up examination was performed using fiberbronchoscopy, which revealed an unobstructed right middle lobe bronchus and sticky yellow sputum. Follow-up chest computed tomography was performed 3 months after the primary surgery and revealed increased expansion of the right middle lobe. We repositioned the right middle lobe successfully by using the 3-cm uniportal VATS approach, but more cases are needed to confirm the feasibility of the approach. Lobectomy remains the primary treatment option for such cases.
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）.

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Video-assisted thoracoscopic surgery(VATS)provides a new approach for treating early-stage lung cancer.Lobectomy by VATS has many advantages over conventional thoracotomy,such as shorter recovery time,less postoperative pain,and faster resumption of a normal lifestyle.However,there is still much debate on the role of VATS in lobectomy for the treatment of lung cancer.Concerns regarding safety,the extent of mediastinal lymph node dissection,and long-term survival have made some surgeons apprehensive of its validity for lung cancer.In this paper,we review the development of thoracoscopy,the present status of VATS for early stage of non-small cell lung cancer(NSCLC),and comparison between VATS and open thoracotomy in the management of NSCLC.
文摘Background Completely video-assisted thoracoscopic Iobectomy is a reasonable treatment for early-stage non-small-cell lung cancer （NSCLC）.At present,the indication for this procedure is stage la and Ib peripheral lung cancer （（〈-）5 cm）; however,for larger tumors,it remains controversial whether this surgical technique is comparable to open Iobectomy.This study aimed to evaluate the safety,completeness,and efficacy of thoracoscopic Iobectomy,and to compare this technique with open Iobectomy for the treatment of non-small-cell lung cancer when the tumor＇s diameter was greater than 5 cm.Methods From May 2001 to April 2011,802 patients underwent a Iobectomy for treatment of non-small-cell lung cancer at our center.In 133 patients,the tumor was 〉 5 cm.There were 98 men and 35 women,median age 63 years （range：29-81 years）.We divided the patients into two groups,group V （completely video-assisted thoracoscopic surgery）,and group T （open Iobectomy）,and evaluated the two groups for age,gender,tumor size,pathological type,location,duration of surgery,blood loss,lymph node dissection,pathological stage,time of drainage,hospitalization,complications,overall survival and recurrence.Results There were 46 cases in group V and 87 cases in group T.Age,gender,tumor size,location,pathological type and stage were similar between the two groups.Group V had shorter operative duration （（186.5±62.8） minutes vs.（256.7±67.5） minutes,P 〈0.001） and reduced bleeding （（218.5±174.6） ml vs.（556.9±187.2） ml,P 〈0.001）.There were no significant differences between the two groups in complications,lymph node dissection,time of drainage and hospitalization.The recurrence between the two groups was equivalent （2.4% vs.3.8%,P=0.670）.The overall survival at 1,2 and 3 years was 95.1%,81.6% and 69.6% for group V and 88.3%,78.8% and 64.0% for group T.Kaplan-Meier survival curves showed that there was no significant differences between the two groups （P=0.129）.Conclusions Completely video-assisted thoracoscopic lobectomy was similar to open lobectomy in safety,completeness,and efficacy,but had a shorter operative duration,and reduced bleeding.This is a minimally invasive procedure that is feasible for a subset of non-small-cell lung cancer patients with tumor size 〉 5 cm.
文摘Background： Both uniportal and triportal thoracoscopic lobectomy and sublobectomy are feasible for early-stage non-small cell lung cancer （NSCLC）. The aim of this study was to compare the perioperative outcomes of uniportal and triportal thoracoscopic Iobectomy and sublobectomy for early-stage NSCLC. Methods： A total of 405 patients with lung lesions underwent thoracoscopic lobectomy or sublobectomy through a uniportal or triportal procedure in approximately 7-month period （From November 2014 to May 2015）. A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes of patients who received uniportal or triportal thoracoscopic lobectomy and sublobectomy. Results： Fifty-eight patients underwent uniportal and 347 patients underwent triportal pulmonary resection. The conversion rate for uniportal and triportal procedure was 3.4% （2/58） and 2.3% （8/347）, respectively. The complication rate for uniportal and triportal procedure was 10.3% and 9.5%, respectively. There was no perioperative death in either group. Most patients had early-stage NSCLC in both groups （uniportal： 45/47, 96%; triportal： 313/343, 91%）. Propensity score-matching analysis demonstrated no significant differences in operation time, intraoperative blood loss, numbers of dissected lymph nodes, number of stations of lymph node dissected, duration of chest tube, and complication rate between uniportal and triportal group for early-stage NSCLC. However, the duration of postoperative hospitalization was longer in the uniportal group （6.83 ± 4.17 vs. 5.42 ± 1.86 d, P = 0.036） compared with the triportal group. Conclusions： Uniportal thoracoscopic lobectomy and sublobectomy is safe and feasible, with comparable short-term outcomes with triportal thoracoscopic pulmonary resection. Uniportal lobectomy and sublobectomy lead to similar cure rate as triportal Iobectomy and sublobectomy for early NSCLC.
文摘BACKGROUND Pulmonary sequestration-both intralobar and extralobar-is a rare congenital developmental malformation.Extralobar pulmonary sequestrations(EPS)have their own pleura but are separated from the bronchus and usually occur in the left lung.They are mainly found mainly between the lower lobe and the mediastinum.EPS is rarely found within the mediastinum itself,even rarer so in the posterior mediastinum.CASE SUMMARY We report the case of a 27-year-old man who was misdiagnosed with a neurogenic tumor based on preoperative contrast-enhanced computed tomography(CT)and magnetic resonance imaging findings.Contrast-enhanced chest CT revealed a posterior mediastinal mass measuring 1.2 cm×1.4 cm×3.3 cm,which consisted of some cystic areas and showed slight enhancement.The mass was in the 11th paravertebral region and attached to the 11th thoracic vertebra behind the descending aorta in the posterior mediastinum.An arteriole originating from the intercostal artery and a vein originating directly from the hemiazygos vein were found in the pedicle of the mass.The mass was resected in a uniport videoassisted thoracoscopic surgery.During the operation,the pyramid-shaped mass appeared well-encapsulated.Postoperative histopathology established a diagnosis of EPS.One month later,a follow-up CT of the thorax showed good recovery.CONCLUSION Although EPS rarely occurs in the posterior mediastinum,its diagnosis should be considered when posterior mediastinal tumors are suspected.
文摘Buitrago and colleagues should be commended on an excellent case report on the effective use of the robotic platform for a successful minimally invasive left lower lobectomy for a patient with biopsy proven squamous cell carcinoma.1 Despite a predicted postoperative forced expiratory volume in one second(ppoFEV1)of 23%and a preoperative diffusing capacity for carbon monoxide(DLCO)of 21%,the patient underwent a lobectomy without any intraoperative complications or evidence of disease at 15 months follow-up.Lymph node sampling was performed from 5 stations.The postoperative length of staywas not clearly stated.The authors made several interesting points about the impact of pulmonary function on postoperative outcomes,the oncological efficacy of lobectomy versus sublobar resections,and merits of roboticassisted thoracoscopic surgery(RATS)versus thoracotomy and conventional video-assisted thoracoscopic surgery(VATS).We would like to discuss these points in further detail based on the available evidence in the current literature.
文摘Background The feasibility of completing a Iobectomy by completely video-assisted thoracoscopic surgery （cVATS） in the management of bronchiectasis is unclear. By retrospectively comparing the outcomes from the Iobectomies that used thoracotomy vs. cVATS, we determined the appropriateness of the minimally invasive cVATS approach in the management of bronchiectasis. Methods Between June 2001 and October 2010, 60 patients with bronchiectasis underwent surgery, of which 56 Iobectomies were performed. All Iobectomies were carried out by either thoracotomy or cVATS approach. Pulmonary vessels and bronchi were manipulated by ligation or stapler in the thoracotomy group, while they were dissected by endo-cutters in the cVATS group. Results There were 21 patients in the thoracotomy group and 35 patients in the cVATS group. Two cVATS patients （5.7%） converted. The difference in operation time, chest tube duration, lengths of hospitalization, and morbidity were not significantly different between the two groups （P 〉0.05）. The blood loss was less in the cVATS group （P=0.015）. A total of 52.4% and 62.9% of patients were postoperatively asymptomatic in the thoracotomy and cVATS groups respectively, and symptomatic improvement was obtained in 38.1% patients by thoracotomy vs. 31.4% patients by cVATS. Conclusion cVATS Iobectomy is safe and effective for the management of bronchiectasis, especially for the patients with localized lesions.
