ABSTRACT
At present, breast cancer ranks first in the incidence of female malignant tumors, and the age of onset tends to be younger. With the development of comprehensive treatment, most patients can survive for a long time or even be cured clinically. How to improve the quality of life to achieve multiple physical, figure and psychological rehabilitation are the focus of clinical research. Traditional surgical methods have many shortcomings, such as large trauma, slow recovery, many complications, poor physical recovery, and great mental blow to patients, it has been unable to meet the overall medical demands. With the promotion of endoscopic technology in clinical application, endoscopic surgery is increasingly widely used in the surgical treatment of breast cancer, and the technical means are more mature. Its advantages such as concealed incision, small incision, low trauma, good cosmetic effect, and fewer complications can make up for the shortcomings of traditional surgical methods, meet the clinical needs of patients, and have huge advantages in the surgical treatment of breast cancer, it is worth for breast surgeons to learn and further promote. This article reviews the application status and prospect of endoscopic technology in surgical treatment of breast cancer.
ABSTRACT
With the increase of the detection rate of ground glass nodules in the lung, a large number of early lung cancers have been found, and thoracoscopic pulmonary segementectomy has been widely used in clinical practice. The identification of intersegmental interface is one of the key steps in thoracoscopic pulmonary segementectomy. In clinical practice, various methods are used to identify inter segment interfaces by natural anatomy of the lung segment, the direction of blood vessel routing, and using some methods to cause differential changes between the target segment and surrounding lung tissue. Currently, the commonly used identification methods have their own advantages and disadvantages. This paper will review the relevant methods currently used in the clinic, hoping to help the clinical practice.
ABSTRACT
Objective:To evaluate the clinical effectiveness of thoracoscopic extended septal myectomy in elderly patients diagnosed with hypertrophic obstructive cardiomyopathy(HOCA).Methods:From April 2019 to August 2021, 36 elderly patients with HOCM who underwent septal myectomy were retrospectively analyzed, including 20 patients under thoracoscopy and 16 patients under median sternotomy.The surgical outcomes, echocardiography and follow-up results were compared between the two groups.Results:The number of intracardiac incisions in the Thoracoscopy group was significantly lower than that in the median thoracotomy group( P=0.001).Additionally, the ventilation time of ≤24 hours was higher in the thoracoscopy group compared to the median thoracotomy group(75.0% vs 31.2%, P=0.017).It is noteworthy that there were no deaths in the thoracoscopic group.However, one patient experienced left ventricular rupture during mitral valve replacement and had to be converted to median sternotomy.This patient also developed low cardiac output syndrome after the operation but was discharged smoothly.In the median sternotomy group, one patient died in the hospital, two patients developed low cardiac output syndrome, and one patient underwent re-sternotomy due to bleeding.Importantly, neither group experienced ventricular septal perforation or complete atrioventricular block.The number of intracardiac incisions in the thoracoscopy postoperative interventricular septal thickness was significantly reduced in both groups.In the thoracoscopic group, the interventricular septal thickness was(19.2±3.5)mm and(11.3±2.2)mm, with a t-value of 8.531 and a p-value of <0.001.In the median sternotomy group, the interventricular septal thickness was(19.9±3.9)mm and(13.1±2.6)mm, with a t-value of 5.664 and a p-value of <0.001.This reduction effectively relieved left ventricular outflow tract obstruction.In the thoracoscopic group, the left ventricular outflow tract obstruction decreased from(96.2±32.9)mmHg to(8.2±3.4)mmHg, with a t-value of 11.894 and a p-value of <0.001.In the median sternotomy group, the left ventricular outflow tract obstruction decreased from(83.2±40.9)mmHg to(13.3±19.3)mmHg, with a t-value of 5.997 and a p-value of <0.001.The patients in the thoracoscopic group were followed up for an average of(13.5±8.8)months, and no complications occurred.The patients in the median sternotomy group were followed up for an average of(15.8±9.4)months.One patient in this group underwent alcohol septal ablation for residual obstruction and developed complete atrioventricular block. Conclusions:Thoracoscopic extended myectomy in elderly patients with(HOCM)can achieve comparable therapeutic effectiveness and safety compared to the median sternotomy approach.This minimally invasive procedure is associated with shorter ventilation time and can also minimize the need for additional intracardiac incisions, especially when simultaneous mitral valve treatment is necessary.
ABSTRACT
Objective:To explore the practical value of general anesthesia with non-intubated spontaneous breathing in uniportal thoracoscopic surgery in elderly patients.Methods:Clinical data of 86 elderly patients undergone uniportal thoracoscopy surgery during hospitalization at our hospital between March 2020 and December 2021 were retrospectively reviewed and analyzed.Based on the anesthesia intubation method, they were divided into a non-intubated spontaneous breathing video-assisted thoracic surgery group(NI-VATS group)and a one-lung ventilation video-assisted thoracic surgery group(OLV-VATS group), with 43 cases in each group.Data were compared on the inflammatory indexes, preparation time for anesthesia, time to awakening after anesthesia, intraoperative lung collapse score, mediastinal flutter score, time to postoperative feeding, digestive tract complications, sore throat, postoperative pulmonary atelectasis, and hospitalization time.Results:Compared with the OLV-VATS group, the NI-VATS group had a shorter anesthesia preparation time [(19.8±2.6)min vs.(32.3±4.5)min, t=-15.77, P<0.001]and a shorter time to awakening [(6.8±2.1)min vs.(11.9±2.9)min, t=-9.485, P<0.001], slightly poorer operating field during surgery, an unfavorable lung collapse score [(2.5±0.7) vs.(1.8±0.7) t=4.704, P<0.001], worse mediastinal flutter [(2.1±0.6) vs.(1.3±0.5), t=6.514, P<0.001]. Lower procalcitonin(PCT)[(0.189±0.130)μg/L vs.(0.264±0.123)μg/L, t=-2.744, P=0.007), a shorter time to postoperative feeding [(3.4±1.0)h vs.(5.5±1.0)h, t=-9.55, P<0.001], and lower rates of digestive tract reactions(4.7% vs.20.9%, χ2=5.108, P=0.024)and throat pain(4.7% vs.23.3%, χ2=6.198, P=0.013), and a shorter length of hospital stay [(3.8±0.3)d vs.(4.9±0.8)d, t=-7.266, P<0.001]. Conclusions:For the elderly patients undergoing uniportal thoracoscopic surgery, non-intubated spontaneous breathing may somewhat obstruct the operating field, but it can shorten the time of anesthesia and the time to awakening, does not increase complications from anesthesia and surgery, favors rapid postoperative recovery for patients and therefore should be promoted.
ABSTRACT
Objective:To explore the effect of perioperative aspirin administration on intraoperative and postoperative bleeding in patients undergoing video-assisted thoracoscopic (VATS) pulmonary wedge resection.Methods:Sixty-three patients scheduled for VATS pulmonary wedge resection in Shougang Hospital of Peking University from November 2020 to April 2022 were randomly assigned in 2 groups. All patients had a history of aspirin taking, patients in study group ( n=32) continued aspirin taking perioperatively, and patients in the control group ( n=31) stopped taking aspirin for 7 days before surgery and resumed taking 3 days after surgery. The volume of intraoperative blood lost, operation time, postoperative drainage volume, thoracic drainage tube placement time, postoperative hospital stay, postoperative thrombosis of lower extremity, perioperative cardiovascular and cerebrovascular events, and postoperative wound healing were documented and compared between the two groups. Results:There were no significant differences in age, gender, oral aspirin time, lesion location, lesion nature, localization, lesion size and underlying disease between the two groups (all P>0.05). All patients successfully completed the operation, and no patients switched to thoracotomy. The intraoperative blood loss in study group and control group was (27.72±12.86) ml and (31.35±13.81) ml ( t=1.08, P=0.283); the operation time was (61.16±10.24) minutes and (61.39±13.79) minutes, respectively ( t=0.08, P=0.940). There were no significant differences in postoperative thoracic drainage, drainage tube placement time, length of hospital stay, incidence of lower extremity thrombosis, incidence of cardiovascular and cerebrovascular events, and rate of poor wound healing between the two groups (all P>0.05). Conclusion:Perioperative administration of aspirin may not increase intraoperative and postoperative bleeding, and the incidence of operation-related complications in patients undergoing VATS pulmonary wedge resection.

The Visual Analog Scale score measured after surgery was (2.12 ± 0.48) points. Three patients had grade 1 complications, with an incidence of complications of 50.00%. Grade 3-5 compilations did not occur in any patient. No patient died during the perioperative period.Conclusion:Subxiphoid video-assisted thoracoscopic extended thymectomy is safe and effective and provides a good visual field. The surgical method allows bilateral thoracic surgery, reduces surgical trauma, and has a broad application prospect.
ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on emergence agitation in the patients undergoing thoracoscopic surgery.Methods:Eighty patients of both sexes, aged 25-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, undergoing elective thoracoscopic surgery under general anesthesia, were divided into 2 groups ( n=40 each) by a random number table method: TEAS group (group T) and control group (group C). In group T, the Hegu (L14), Zusanli (ST36) and Sanyinjiao (SP6) were stimulated starting from 30 min before induction of anesthesia until the end of operation, with a frequency of 2/100 Hz and disperse-dense waves.The intensity of stimulation was the maximum current that patients could tolerate.In group C, stimulating electrodes were placed at the same acupoints before induction, but no electrical stimulation was applied.Ramsay sedation score and VAS score were recorded.and emergence agitation was assessed using RSS agitation score.Blood samples from the median cubital vein or internal jugular vein were collected before anesthesia induction (T 1), at the end of surgery (T 2), immediately after removal of tracheal tube (T 3) and at 15 min after removal of tracheal tube (T 4) for determination of serum interleukin-6 (IL-6) and IL-10 concentrations by enzyme-linked immunosorbent assay.The intraoperative consumption of propofol, remifentanil and sufentanil was recorded.Adverse reactions such as tachycardia, bradycardia, hypertension, hypotension, respiratory depression, delay of awakening and nausea and vomiting were recorded after operation. Results:Compared with group C, the amount of intraoperative remifentanil consumed was significantly decreased, serum IL-6 concentrations were decreased, and the serum IL-10 concentration was increased T 2-4, Ramsay sedate score was increased, and the incidence of agitation was decreased in group T ( P<0.05). There was no significant difference in VAS score and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can reduce the development of emergence agitation in the patients undergoing thoracoscopic surgery, which is related to inhibition of inflammatory responses.
ABSTRACT
Objective:To investigate the predictive value of 18F-FDG PET-CT in the conversion from thoracoscopic lobectomy to thoracotomy for non-small cell lung cancer (NSCLC). Methods:The clinical data, CT and PET-CT images of 193 patients with primary NSCLC undergoing thoracoscopic surgery from January 2014 to June 2021 at China-Japan Friendship Hospital were retrospectively analyzed. All patients were divided into 45 cases who were converted to thoracotomy (the conversional group) and 148 cases who were not converted to thoracotomy (the non-conversional group). Univariate analysis was performed on clinicopathological characteristics and image parameters. Multivariate logistic regression was used to analyze the factors affecting the conversion to thoracotomy. Taking the final conversion to thoracotomy or not as the gold standard, the predictive effect of variables in the conversion to thoracotomy was analyzed through the receiver operating characteristic (ROC) curve. Delong test was used to compare the area under the curve (AUC) predicted by all variables.Results:In the conversional group, the proportion of peribronchial lymph node (PLN), peribronchial cuffs of soft (PCS), pleural calcification, pulmonary nodule calcification, PLN or PCS calcification or increased density on chest CT was higher than that in the non-conversional group (all P<0.05); and the maximum standardized uptake value (SUV max) of PET in the conversional group was higher compared with that in the non-conversional group ( P<0.001). Univariate logistic regression analysis suggested age ( OR = 4.663,95% CI 2.191- 9.923, P < 0.001) and PLN or PCS density of chest CT scan ( OR = 2.824, 95% CI 1.791-7.303, P < 0.001) were independent influencing factors of the conversion from thoracoscopic lobectomy to thoracotomy. ROC analysis showed that the effect of the conversion to thoracotomy predicted by the combination of 18F-FDG PET and chest CT [AUC = 0.891 (95% CI 0.831-0.951); the optimal cut-off value of SUV max and CT was 3.45, 70 Hu: the sensitivity was 84.4%, the specificity was 83.8%] was better than that by chest CT alone [AUC = 0.678 (95% CI 0.591-0.766); the optimal cut-off value of CT was 70 Hu: the sensitivity was 62.2%, the specificity was 62.8%; P < 0.001] and by age [AUC = 0.625 (95% CI 0.532-0.719); the optimal cut-off value was 65.5 years: the sensitivity was 75.6%, the specificity was 60.1%; P < 0.001]. Conclusions:PLN or PCS density on chest scan and age are valuable in predicting the conversion from thoracoscopic lobectomy to thoracotomy for NSCLC patients. The combination of PET and CT has an additional role in predicting the conversion to thoracotomy during thoracoscopic lobectomy.
ABSTRACT
Objective:To investigate the effects of one-lung ventilation with a laryngeal mask airway combined with a bronchial blocker on respiratory function in older adult patients undergoing thoracoscopic surgery.Methods:Sixty older adult patients who underwent thoracoscopic surgery in Zhejiang Veteran Hospital from January 2019 to December 2020 were included in this study. They were randomly divided into a single group (a simple bronchial blocker) and a combined group (a bronchial blocker combined with a laryngeal mask airway), with 30 patients in each group. Awakening (time to extubation, spontaneous respiration and eye opening), respiratory function [peripheral oxygen saturation, vital capacity, maximum voluntary ventilation measured before and 3 days after surgery], hemodynamics [heart rate and mean arterial pressure were recorded before (T 1) and immediately after placement of a bronchial blocker or a laryngeal mask (T 2) and at the time of removal of a bronchial block or a laryngeal mask (T 3)], and adverse events (hoarseness, throat pain, dysphagia and choking) were recorded. Results:Time to extubation, time to spontaneous respiration, and time to eye opening in the combined group were (5.62 ± 1.23) minutes, (6.85 ± 1.34) minutes, and (7.34 ± 1.52) minutes, respectively, which were significantly shorter than (8.62 ± 1.55) minutes, (10.25 ± 1.78) minutes, (11.38 ± 1.85) minutes in the single group ( t = 9.94, 10.00, 11.06, all P < 0.05). At 3 days after surgery, peripheral oxygen saturation, vital capacity, and maximum voluntary ventilation in the combined group were (98.23 ± 1.05)%, (2.18 ± 0.60) L, (54.23 ± 5.36) L, respectively, which were significantly higher than (96.23 ± 1.01)%, (1.82 ± 0.50) L, (48.12 ± 4.23) L in the single group ( t = 7.51, 2.52, 4.90, all P < 0.05). Mean arterial pressure measured at T 3 was significantly lower in the combined group than that in the single group [(98.25 ± 2.32) mmHg vs. (93.35 ± 2.48) mmHg, t = 7.90, P < 0.05]. The incidences of hoarseness, throat pain and choking in the combined group were 6.66% (2/30), 10.00% (3/30), 6.66% (2/30), respectively , which were significantly lower than 33.33% (10/30), 43.33% (13/30), 43.33% (13/30) in the single group (χ 2 = 6.66, 8.52, 10.75, all P < 0.05). There was no significant difference in the incidence of dysphagia between the two groups ( P > 0.05). Conclusion:Use of a laryngeal mask airway combined with a bronchial blocker during thoracoscopic surgery in older adult patients facilitates postoperative recovery, has little impact on hemodynamics, and is highly safe.

Objective:To proceed a comparative study of characteristics and safety of video-assisted thoracoscopic thymectomy between artificial pneumothorax combining subxiphoid-costal margin approach versus right thoracic cavity approach.Methods:From January 2018 to December 2021, 251 patients(including myasthenia gravis with thymic hyperplasia or thymoma, thymic cysts and anterior mediastinal occupying lesions)undergoing thoracoscopic extended thymectomy in our department were retrospectively studied, and their clinical data were collected.The surgical methods were divided into artificial pneumothorax combining xiphoid costal margin approach(artificial pneumothorax group, n=165)and via right thoracic approach(right thoracic group, n=86). Clinical data such as preoperative information, operative duration, blood loss, postoperative drainage, drainage duration, and surgical complication were compared between two groups.Results:There were no statistical differences in age, gender and pathology between two groups(all P>0.05). Compared with the right thoracic group, operative duration[(108.6±45.2)min vs.(127.6±42.1)min, t=-3.628, P=0.000], intraoperative blood loss[(37.9±131.7)ml vs.(107.4±284.8)ml, t=-8.215, P=0.000], postoperative drainage volume[(379.0±285.5)ml vs.(646.6±373.3 ml), t=-6.277, P=0.000]and drainage duration[(2.2±1.0)d vs.(3.1±1.0)d, t=-7.275, P=0.000]were statistically significantly decreased in the artificial pneumothorax group.No significant difference was found(all P>0.05)in phrenic nerve injury(1/165 vs.0/86, P=1.000), myasthenia crisis(3/89 vs.2/66, χ2=0.014, P=0.906), and the conversion to thoracotomy(3/165 vs.2/86, P=1.000). Conclusions:VATS thymectomy by artificial pneumothorax combining subxiphoid-costal margin approach is a safer method, having a less trauma, less bleeding and less incidence rate of complication.Especially, it is more suitable for elderly female patients who cannot be intubated in double lumen, cannot tolerate one-lung ventilation, and have pulmonary insufficiency.
ABSTRACT
Objective:To retrospectively analyze the efficacy of video-assisted thoracoscopic surgery (VATS) in the treatment of solitary pulmonary nodule (SPN) and related factors affecting the diagnosis of benign and malignant SPN.Methods:The clinical data and surgical conditions of 317 patients with SPN who were resected by VATS and diagnosed by pathology in Chaoyang Central Hospital from January 2017 to December 2019 were retrospectively analyzed.The patient′s surgical efficacy and corresponding imaging features were explored.Results:Of the 317 patients, 124 (39.1%) cases underwent uniportal VATS and 193(60.9%) cases underwent multi-portal-portal VATS, 195(61.5%) cases had lobectomy, 16(5.1%) cases had anatomical segmentectomy, and 106(33.4%) cases had wedge resection. The operation time of the whole group was 50 - 210 (146.5 ± 34.7) min, intraoperative blood loss was 10 - 180 (69.3 ± 31.5) ml, thoracic drainage tube retention time was 2 - 7 (3.7 ± 1.4) d, postoperative hospital stay was 3 - 21 (6.4 ± 1.8) d, and the complication rate was 1.0%(3/317). No perioperative death occurred. Among all the nodules, 98(31.0%) cases were benign nodules and 219(69.1%) cases were malignant. Multivariate analysis showed that maximum nodule diameter, lobulated sign, burr sign, vascular bundle sign and pleural sag sign were independent related factors for the diagnosis of benign and malignant nodules ( P<0.05). Conclusions:VATS has less trauma and fewer complications, which has important clinical value for the diagnosis and treatment of benign and malignant SPN. Nodule maximum diameter, lobulated sign, burr sign, vascular bundle sign, pleural pit sign are independent related factors that affect the diagnosis of benign and malignant SPN.
ABSTRACT
Objective: To observe the complications and impact factors of microcoil locating of pulmonary nodules before video-assisted thoracoscopic resection (VATS). Methods: A retrospective analysis was performed on 160 patients with pulmonary nodules (160 nodules) who underwent CT guided microcoil location of pulmonary nodules before VATS. Postoperative complications were counted, and the impact factors of relative complications of microcoil location were analyzed. Results: Nodules were successfully located in all 160 cases. Pneumothorax and pulmonary hemorrhage were found in 26 and 37 cases, respectively, while no air embolism occurred. All patients underwent VATS on the next day, and no microcoil displacement was found during operation. Univariate analysis showed that the patient's position (P=0.04), the distance from nodule to pleura (P=0.03) and the times of puncture (P<0.01) were related to pneumothorax, while the distance from nodule to pleura (P=0.03) was related to pulmonary hemorrhage. Multivariate analysis showed that the patient's position, the distance from nodule to pleura and the times of puncture were all independent risk factors for pneumothorax (all P<0.05), and the distance from nodule to pleura was the independent risk factor for pulmonary hemorrhage after locating of microcoil (P=0.01). Conclusion: Pneumothorax and pulmonary hemorrhage might occur after microcoil location of lung nodules before VATS. Pneumothorax related to the distance from nodule to pleura, patient's position and the times of puncture, while pulmonary hemorrhage only related to the distance from nodule to pleura.
ABSTRACT
Objective: To observe the value of CT-guided localization of small pulmonary nodule with new pulmonary nodule locating needle before thoracoscopic surgery. Methods: Totally 50 patients with 53 small pulmonary nodules (diameter 5.0-15.0 mm) were retrospectively analyzed. All patients underwent video-assisted thoracoscopic surgery (VATS) after CT-guided localization. The positioning effect and complications were observed. Results: The anchor positioning needle was successfully implanted in 53 lesions of 50 patients, and the positioning success rate was 100% (53/53). During the puncture process, minor bleeding occurred near puncture needle passage in 9 cases (9/50, 18.00%), while mild pneumothorax and pleural reaction were noticed during the localization operation in 14 cases (14/50, 28.00%) and 1 case (1/50, 2.00%), respectively. VATS was performed on the day of positioning in 8 cases and on the next day of positioning in 42 cases. All 53 nodules were successfully found and removed according to the guidance of positioning needle. Conclusion: CT-guided localization of small pulmonary nodule with new pulmonary nodule locating needle before VATS was effective and safe.
ABSTRACT
Objective: To observe the value of CT-guided accurate localization of small pulmonary nodule with memory alloy coils before video-assisted thoracoscopic surgery (VATS). Methods: Totally 92 patients (102 small pulmonary nodules) underwent localization of small pulmonary nodules with memory alloy coils before VATS were enrolled. VATS was performed within 24 h after localization. The localization effect and complications were observed. Results: The success rate of localization of 102 small pulmonary nodules was 98.04% (100/102), and the operation time of localization for each lesion ranged 8 min to 45 min, with the average time of (17.26±5.92)min. The memory alloy coils of 2 patients took off from lung tissue and remained in the chest wall in VATS. After localization, the incidence of small amount of pneumothorax was 10.78% (11/102), of small amount alveolar hemorrhage was 12.75% (13/102), whereas the patients had no symptom and untreated. VATS was successfully performed for 102 small pulmonary nodules without conversion to thoracotomy. Conclusion: CT-guided accurate localization of small pulmonary nodule with memory alloy coils before VATS is effective and safe.
ABSTRACT
Objective To investigate the effect of the amputation order of pulmonary artery and pulmonary artery on pulmonary residual blood volume in total thoracoscopic lobectomy.Methods Sixtyeight patients who were scheduled to underwent total thoracoscopic lobectomy from June 2015 to April 2019 in Beijing Aerospace General Hospital were selected.The patients were divided into first amputation pulmonary artery group and first amputation pulmonary vein group by random envelope method with 34 cases in each group.Five cases in first amputation pulmonary artery group and 4 cases in first amputation pulmonary vein group were excluded because of the procedure modification or the fragmentation of the specimen during the course of operation.In the end,29 cases were enrolled in first amputation pulmonary artery group and 30 cases in first amputation pulmonary vein group.In first amputation pulmonary vein group,all arteries were ligated before interruption of the veins;and in first amputation pulmonary artery group had a reverse sequence.The perioperative period status were recorded,and the crude pulmonary quality,dry pulmonary quality,pulmonary residual blood volume and adjusted pulmonary residual blood ratio were measured or calculated.Results All 59 patients were operated successfully.No serious complications occurred,no perioperative death occurred,and no patients needed blood transfusion.There was no statistical difference in the incidence of minor complications between first amputation pulmonary artery group and first amputation pulmonary vein group:27.6％ (8/29) vs.33.3％ (10/30),P＞0.05.There were no statistical differences in operative time,transoperative bleeding volume,pulmonary residual blood volume,crude pulmonary quality,dry pulmonary quality,adjusted pulmonary residual blood ratio,hemoglobin difference before and after surgery,postoperative drainage time and postoperative hospitalization time between 2 groups (P＞0.05).Conclusions The amputation order of pulmonary artery and pulmonary vein sequence of vessel interruption during total thoracoscopic lobectomy has no effect on the pulmonary residual blood volume,can be reasonably selected according to the intraoperative situation.
