Third-Degree Atrioventricular Block And Asystole After Lung Resection: A Rare Complication.

Surgical resection remains the optimal therapeutic option for early-stage operable NSCLC. Despite significant advances in recent years related to anesthetic and surgical techniques, cardiopulmonary complications remain major causes for postoperative morbimortality. In this paper we present a case of a patient who developed complete AV block followed by asystole after lung resection surgery. The patient underwent surgery via right VATS and the procedure was uneventful.  On the first post-operative day patient developed a third-degree atrioventricular block followed by 6 seconds asystole. Pharmacological treatment was instituted and implementation of a permanent pacemaker occurred on the third post-operative day, without complications. The remaining postoperative course was uneventful and the patient was discharged home on the sixth post-operative day. It is the objective of the authors to report and highlight this rare and potencial fatal complication of lung resection.

Results Of Minimally Invasive Vats Thymectomy In Miastenia Gravis Patients Compared With More Invasive Approaches - 10-Year Experience In A Single Center.

INTRODUCTION: Myasthenia gravis (MG) is an autoimmune, neurologic disease that causes a wide range of symptoms. While the transsternal, transcervical and thoracotomy approaches are accepted as effective, there is still debate regarding the VATS approach. MATERIALS AND METHODS: We analyzed our center's surgical experience with thymectomy for myasthenia gravis, comparing the results of patients operated on using VATS and more invasive approaches, over a period of 10 years. A search of the department's surgical database for myasthenia gravis cases between January 2010 and January 2021, revealed a total of 40 cases. Twenty-four patients were included in the final analysis and were distributed into two groups: the VATS procedure group (group A) and the open procedure group (group B). The latter included sternotomy, thoracotomy, transcervical and hemiclamshell approaches. Only radical thymectomies were included. The established outcomes were clinical improvement defined as asymptomatic remission, reduction, or discontinuation of the medication necessary to achieve optimal symptom control. RESULTS: The median follow-up time was 27 months (ranging from 4 to 75 months). Videothoracoscopy radical thymectomy was performed on 12 patients. Complete remission with no medication was achieved in 1 case (8.3%), while 2 patients (16.7%) became asymptomatic with reduced medication. An improvement (reduced symptoms or decreased medication) was observed in 8 cases (66.6%). No change in clinical outcome was noted in 1 patient (8.3%). None of the patients reported worsening symptoms. Open thymectomy was performed on 12 patients. Complete remission with no medication was achieved in 1 case (8.3%), while 2 patients (16.7%) became asymptomatic with reduced medication. An improvement was noted in 6 cases (50%). No change in clinical outcome was observed in 3 patients (25%) whereas 2 of them (16.7%) experienced slightly better symptom control but with a significant increase in medication. One patient (8.3%) described the clinical results as without any significant change. None of the patients reported worsening symptoms. CONCLUSION: The videotoracoscopic approach in the treatment of myasthenia gravis is non-inferior compared to the open approach and effective in a long-term follow-up, offering all the additional benefits of less invasive surgery.

Association between mechanical power during one-lung ventilation and pulmonary complications after thoracoscopic lung resection surgery: a prospective observational study.

BACKGROUND: The role of mechanical power on pulmonary outcomes after thoracic surgery with one-lung ventilation was unclear. We investigated the association between mechanical power and postoperative pulmonary complications in patients undergoing thoracoscopic lung resection surgery. METHODS: In this single-center, prospective observational study, 622 patients scheduled for thoracoscopic lung resection surgery were included. Volume control mode with lung protective ventilation strategies were implemented in all participants. The primary endpoint was a composite of postoperative pulmonary complications during hospital stay. Multivariable logistic regression models were used to evaluate the association between mechanical power and outcomes. RESULTS: The incidence of pulmonary complications after surgery during hospital stay was 24.6% (150 of 609 patients). The multivariable analysis showed that there was no link between mechanical power and postoperative pulmonary complications. CONCLUSIONS: In patients undergoing thoracoscopic lung resection with standardized lung-protective ventilation, no association was found between mechanical power and postoperative pulmonary complications.

[Effect of transcutaneous electrical acupoint stimulation on postoperative cough in lung cancer patients undergoing video-assisted thoracoscopic surgery].

OBJECTIVE: To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) for alleviating postoperative cough in lung cancer patients undergoing video-assisted thoracoscopic surgery. METHODS: A total of 110 patients with lung cancer undergoing video-assisted thoracoscopic surgery were randomly divided into a TEAS group (55 cases, 2 cases dropped out) and a sham-TEAS group (55 cases, 4 cases dropped out). In the TEAS group, TEAS was delivered 30 min before anesthesia and on day 1 to day 4 after operation separately, with disperse-dense wave, in frequence of 2 Hz/100 Hz. The acupoints included Feishu (BL 13), Pishu (BL 20), Shenshu (BL 23), Hegu (LI 4), Lieque (LU 7) and Taixi (KI 3) on the both sides. In the sham-TEAS group, at the same time points and same acupoints as the TEAS group, the electrode pads were attached to the acupoints, but without electric stimulation. The interventions were given 30 min each time, once daily in the two groups. The incidence of cough and the scores of visual analogue scale (VAS) for cough on the first day (T1), the third day (T2), the fifth day (T3), 1 month (T4) and 3 months (T5) after operation, as well as the scores of the Leicester cough questionnaire (LCQ) on T4 and T5 were compared between the two groups; the contents of serum C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were detected before surgery (T0) and at T1, T2 and T3. The first flatus time, the first defecation time, the first ambulation time, the postoperative hospital day and the incidence of postoperative nausea and vomiting were compared between the two groups. RESULTS: Compared with the sham-TEAS group, the cough incidence at T3 and cough VAS scores at T1 to T5 were lower in the TEAS group (P<0.05, P<0.01), and the LCQ scores at T4 and T5 were higher (P<0.05). The serum contents of CRP, IL-6 and TNF-αat T1 to T3 in the TEAS group were lower than those of the sham-TEAS group (P<0.01). The first flatus time, the first defecation time and the first ambulation time were earlier (P<0.05, P<0.01); and the postoperative hospital day was shorter (P<0.05) and the incidence of postoperative nausea and vomiting was lower (P<0.05) in the TEAS group when compared with those of the sham-TEAS group. CONCLUSION: TEAS relieves cough in lung cancer patients undergoing video-assisted thoracoscopic surgery, improves quality of life and promotes the early postoperative recovery.

Pulmonary Rehabilitation Exercises Effectively Improve Chronic Cough After Surgery for Non-small Cell Lung Cancer.

INTRODUCTION: Cough is a major complication after lung cancer surgery, potentially impacting lung function and quality of life. However, effective treatments for managing long-term persistent postoperative cough remain elusive. In this study, we investigated the potential of a pulmonary rehabilitation training program to effectively address this issue. METHODS: Between January 2019 and December 2022, a retrospective review was conducted on patients with non-small cell lung cancer (NSCLC) who underwent lobectomy and lymph node dissection via video-assisted thoracoscopic surgery (VATS) at Daping hospital. Based on their postoperative rehabilitation methods, the patients were categorized into 2 groups: the traditional rehabilitation group and the pulmonary rehabilitation group. All patients underwent assessment using the Leicester cough questionnaire (LCQ) on the third postoperative day. Additionally, at the 6-month follow-up, patients' LCQ scores and lung function were re-evaluated to assess the long-term effects of the pulmonary rehabilitation training programs. RESULTS: Among the 276 patients meeting the inclusion criteria, 195 (70.7%) were in the traditional rehabilitation group, while 81 (29.3%) participated in the pulmonary rehabilitation group. The pulmonary rehabilitation group showed a significantly lower incidence of cough on the third postoperative day (16.0% vs 29.7%, P = .018) and higher LCQ scores in the somatic dimension (5.09 ± .81 vs 4.15 ± 1.22, P = .007) as well as in the total score (16.44 ± 2.86 vs 15.11 ± 2.51, P = .018, whereas there were no significant differences in psychiatric and sociological dimensions. At the 6-month follow-up, the pulmonary rehabilitation group continued to have a lower cough incidence (3.7% vs 12.8%, P = .022) and higher LCQ scores across all dimensions: somatic (6.19 ± .11 vs 5.75 ± 1.20, P = .035), mental (6.37 ± 1.19 vs 5.85 ± 1.22, P = .002), sociological (6.76 ± 1.22 vs 5.62 ± 1.08, P < .001), and total (18.22 ± 2.37 vs 16.21 ± 2.53, P < .001). Additionally, lung function parameters including FVC, FVC%, FEV1, FEV1%, MVV, MVV%, DLCO SB, and DLCO% were all significantly higher in the pulmonary rehabilitation group compared to the traditional group. CONCLUSION: Pulmonary rehabilitation exercises significantly reduced the incidence of postoperative cough and improved cough-related quality of life in patients undergoing lobectomy, with sustained benefits observed at the 6-month follow-up. Additionally, these exercises demonstrated superior lung function outcomes compared to traditional rehabilitation methods.

Pulmonary rehabilitation exercises significantly reduced the incidence of postoperative cough and improved cough-related quality of life in patients undergoing lobectomy, with sustained benefits observed at the 6-month follow-up. Additionally, these exercises demonstrated superior lung function outcomes compared to traditional rehabilitation methods.

Risk factors for postoperative pulmonary complications in elderly patients undergoing video-assisted thoracoscopic surgery lobectomy under general anesthesia: a retrospective study.

BACKGROUND: The objective of this study is to identify and evaluate the risk factors associated with the development of postoperative pulmonary complications (PPCs) in elderly patients undergoing video-assisted thoracoscopic surgery lobectomy under general anesthesia. METHODS: The retrospective study consecutively included elderly patients (≥ 70 years old) who underwent thoracoscopic lobectomy at Xuanwu Hospital of Capital Medical University from January 1, 2018 to August 31, 2023. The demographic characteristics, the preoperative, intraoperative and postoperative parameters were collected and analyzed using multivariate logistic regression to identify the prediction of risk factors for PPCs. RESULTS: 322 patients were included for analysis, and 115 patients (35.7%) developed PPCs. Multifactorial regression analysis showed that ASA ≥ III (P = 0.006, 95% CI: 1.230 ∼ 3.532), duration of one-lung ventilation (P = 0.033, 95% CI: 1.069 ∼ 4.867), smoking (P = 0.027, 95% CI: 1.072 ∼ 3.194) and COPD (P = 0.015, 95% CI: 1.332 ∼ 13.716) are independent risk factors for PPCs after thoracoscopic lobectomy in elderly patients. CONCLUSION: Risk factors for PPCs are ASA ≥ III, duration of one-lung ventilation, smoking and COPD in elderly patients over 70 years old undergoing thoracoscopic lobectomy. It is necessary to pay special attention to these patients to help optimize the allocation of resources and enhance preventive efforts.

The role of the early video-assisted thoracoscopic surgery in children with pleural empyema.

PURPOSE: Pleural empyema (PE) is a collection of purulent material in the pleural space. PE's management in children is a challenge and an inappropriate diagnostic-therapeutic work up can lead to serious short and long-term complications. The aim of this study is to define the correct timing to approach a pediatric PE by video-assisted thoracoscopic surgery (VATS). METHODS: A retrospective observational study was conducted including pediatric patients who underwent video-assisted thoracoscopy for pleural empyema between May 2005 and September 2022. RESULTS: 62 patients were subjected to VATS for PE (32 in Group Early VATS, 30 in Group Late VATS). It emerged that the elapsed period between the onset of symptoms and surgery correlates in a statistically significant way with the post-operative stay in intensive care (z score 4.3 and p value < 0.0001) and the analysis between early VATS, late VATS and postoperative hospitalization showed a statistically significant reduction of the post-operative hospitalization in the early VATS groups (p value < 0.02). CONCLUSIONS: VATS resulted to be safe and effective for the treatment of PE in children, and an early minimally invasive thoracoscopic intervention (early VATS) correlates with better outcomes, specifically in terms of intensive care hospitalization and overall hospitalization.

Video-Assisted vs Robotic-Assisted Lung Lobectomies for Operating Room Resource Utilization and Patient Outcomes.

Importance: With increased use of robots, there is an inadequate understanding of minimally invasive modalities' time costs. This study evaluates the operative durations of robotic-assisted vs video-assisted lung lobectomies. Objective: To compare resource utilization, specifically operative time, between video-assisted and robotic-assisted thoracoscopic lung lobectomies. Design, Setting, and Participants: This retrospective cohort study evaluated patients aged 18 to 90 years who underwent minimally invasive (robotic-assisted or video-assisted) lung lobectomy from January 1, 2020, to December 31, 2022, with 90 days' follow-up after surgery. The study included multicenter electronic health record data from 21 hospitals within an integrated health care system in Northern California. Thoracic surgery was regionalized to 4 centers with 14 board-certified general thoracic surgeons. Exposures: Robotic-assisted or video-assisted lung lobectomy. Main Outcomes and Measures: The primary outcome was operative duration (cut to close) in minutes. Secondary outcomes were length of stay, 30-day readmission, and 90-day mortality. Comparisons between video-assisted and robotic-assisted lobectomies were generated using the Wilcoxon rank sum test for continuous variables and the χ2 test for categorical variables. The average treatment effects were estimated with augmented inverse probability treatment weighting (AIPTW). Patient and surgeon covariates were adjusted for and included patient demographics, comorbidities, and case complexity (age, sex, race and ethnicity, neighborhood deprivation index, body mass index, Charlson Comorbidity Index score, nonelective hospitalizations, emergency department visits, a validated laboratory derangement score, a validated institutional comorbidity score, a surgeon-designated complexity indicator, and a procedural code count), and a primary surgeon-specific indicator. Results: The study included 1088 patients (median age, 70.1 years [IQR, 63.3-75.8 years]; 704 [64.7%] female), of whom 446 (41.0%) underwent robotic-assisted and 642 (59.0%) underwent video-assisted lobectomy. The median unadjusted operative duration was 172.0 minutes (IQR, 128.0-226.0 minutes). After AIPTW, there was less than a 10% difference in all covariates between groups, and operative duration was a median 20.6 minutes (95% CI, 12.9-28.2 minutes; P < .001) longer for robotic-assisted compared with video-assisted lobectomies. There was no difference in adjusted secondary patient outcomes, specifically for length of stay (0.3 days; 95% CI, -0.3 to 0.8 days; P = .11) or risk of 30-day readmission (adjusted odds ratio, 1.29; 95% CI, 0.84-1.98; P = .13). The unadjusted 90-day mortality rate (1.3% [n = 14]) was too low for the AIPTW modeling process. Conclusions and Relevance: In this cohort study, there was no difference in patient outcomes between modalities, but operative duration was longer in robotic-assisted compared with video-assisted lung lobectomy. Given that this elevated operative duration is additive when applied systematically, increased consideration of appropriate patient selection for robotic-assisted lung lobectomy is needed to improve resource utilization.

Radicality of mediastinal lymphadenectomy in minimally invasive pulmonary resection: a comparative analysis of uniportal and multiportal thoracoscopic approaches.

INTRODUCTION: Lung cancer is a serious health problem with a high mortality rate. In the context of surgical management, minimally invasive approaches, including uniportal thoracoscopic techniques, offer potential benefits such as faster recovery and increased patient cooperation. The aim of this study was to compare the accessibility of the mediastinal lymph nodes between uniportal and multiportal thoracoscopic approaches and to verify whether the use of the uniportal approach affects the radicality of the lymphadenectomy. METHODS: A comparative study conducted from January 2015 to July 2022 at the University Hospital Ostrava focused on evaluating the radicality of mediastinal lymphadenectomy between subgroups of patients undergoing surgery using the uniportal thoracoscopic approach and the multiportal thoracoscopic approach. RESULTS: A total of 278 patients were included in the study. There were no significant differences in the number of available lymphatic stations between the subgroups. The mean number of lymph node stations removed was 6.46 in the left hemithorax and 6.50 in the right hemithorax. Thirty-day postoperative morbidity for the entire patient population was 24.5%, with 18.3% having minor complications and 3.6% having major complications. The overall mortality rate in the study population was 2.5%, with a statistically significant difference in mortality between uniportal and multiportal approaches (1.0% vs 6.4%, p=0.020). CONCLUSIONS: The uniportal approach demonstrated comparable accessibility and lymph node yield to the multiportal approach. There was also no difference in postoperative morbidity between the two approaches. The study suggests the possibility of lower mortality after uniportal lung resection compared with multiportal lung resection, but this conclusion should be interpreted with caution.

Video-assisted thoracic surgery and robotic-assisted first-rib excision and thoracic outlet syndrome decompression.

Multiple surgical approaches have been used in the management of thoracic outlet syndrome. These approaches have traditionally been "open" approaches and have been associated with the inherent morbidities of an open approach, including a risk of injury to the neurovascular structures due to traction and trauma while resecting the first rib. In addition, there has been concern that recurrence of symptoms may be related to incomplete resection of the rib with conventional open techniques. With the advent of minimally invasive thoracic surgery, surgeons began to explore first-rib resection via a thoracoscopic approach. Unfortunately, the existing video-assisted thoracic surgery technology and equipment was not well suited to working in the apex of the chest. With the introduction and subsequent progress in robotic surgery and instrumentation, this dissection can be performed with all the advantages of robotics, but also with minimal traction and trauma to the neurovascular structures, and incorporates almost complete resection of the rib with minimal residual stump. Robotics has developed as a reliable, safe, and less invasive approach to first-rib resection, yielding excellent results while limiting the morbidity of the procedure.

Advantages of robot-assisted resection of large mediastinal tumors: a single-center preliminary study.

Current study aims to assess the safety and efficacy of robot-assisted thoracoscopic surgery (RATS) for sizable mediastinal masses with a minimum diameter ≥6 cm, compared with video-assisted thoracoscopic surgery (VATS) and open surgery. This study enrolled 130 patients with mediastinal tumors with no less than 6 cm diameter in Zhongnan Hospital, Wuhan University, including 33 patients who underwent RATS, 52 patients who underwent VATS and 45 patients who underwent open surgery. After classifying based on mass size and whether it has invaded or not, we compared their clinical characteristics and perioperative outcomes. There was no significant difference in age, gender, mass size, myasthenia gravis, mass location, pathological types (p > 0.05) in three groups. Patients undergoing open surgery typically presenting at a more advanced stage (p < 0.05). No obvious difference was discovered in the average postoperative length of stay, operation duration, chest tube duration and average postoperative day 1 drainage output between RATS group and VATS group (p > 0.05), while intraoperative blood loss in RATS group was significantly lower than VATS group (p = 0.046). Moreover, the postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss in RATS group were significantly lower than open surgery group (p < 0.001). RATS is a secure and efficient approach for removing large mediastinal masses at early postoperative period. In comparison with VATS, RATS is associated with lower intraoperative blood loss. Compared with open surgery, RATS is also associated with shorter postoperative length of stay, operation duration, chest tube duration and intraoperative blood loss.

Export priority technique for Uni-portal thoracoscopic left upper lobectomy.

BACKGROUND: Further explore the safety and feasibility of Uni-portal video assisted thoracoscopic (UVATS) left upper lobectomy by optimizing the treatment of incisions and blood vessels. METHODS: We conducted a retrospective analysis of data from 32 patients who underwent UVATS left upper lobectomy and systematic mediastinal lymph node dissection utilizing the Export priority technique between January 2021 and December 2022. We documented perioperative indicators, including surgical time, intraoperative blood loss, the number of lymph nodes dissected, and postoperative pathological staging. RESULTS: All surgeries were conducted utilizing the Export priority technique in UVATS. The mean surgical duration was (98.93 ± 14.98) minutes, with an average intraoperative blood loss of (79.53 ± 37.96) ml. The mean count of dissected lymph nodes was (13.96 ± 2.69). The length of hospital Stay averaged (5.62 ± 1.81) days. On the first postoperative day, the thoracic drainage volume was (101.87 ± 49.46) ml. The mean duration of postoperative thoracic tube insertion was (3.1 ± 1.84) days. No occurrences of postoperative hoarseness, pulmonary infection, or complications such as bronchopleural fistula were observed. CONCLUSION: The application of the Export priority technique improves the safety and feasibility of UVATS left upper lobectomy.

Efficacy and safety of video double-lumen tube intubation in lateral position in patients undergoing thoracic surgery: a randomized controlled trial.

BACKGROUND: Video double-lumen tube (VDLT) intubation in lateral position is a potential alternative to intubation in supine position in patients undergoing thoracic surgery. This non-inferiority trial assessed the efficacy and safety of VDLT intubation in lateral position. METHODS: Patients (18-70 yr) undergoing right thoracoscopic lung surgery were randomized to either the left lateral position group (group L) or the supine position group (group S). The VDLT was placed under video larygoscopy. The primary endpoint was the intubation time. Secondary endpoints included VDLT displacement rate, intubation failure rate, the satisfaction of surgeon and nurse, and intubation-related adverse events. RESULTS: The analysis covered 80 patients. The total intubation time was 52.0 [20.4]s in group L and 34.3 [13.2]s in group S, with a mean difference of 17.6 s [95% confidence interval (CI): 9.9 s to 25.3 s; P = 0.050], failing to demonstrate non-inferiority with a non-inferiority margin of 10 s. Group L, compared with group S, had significantly lower VDLT displacement rate (P = 0.017) and higher nurse satisfaction (P = 0.026). No intubation failure occurred in any group. Intubation complications (P = 0.802) and surgeon satisfaction (P = 0.415) were comparable between two groups. CONCLUSIONS: The lateral VDLT intubation took longer time than in the supine position, and non-inferiority was not achieved. The incidence of displacement as the secondary endpoint was lower in the L group, possibly due to changing body positions beforehand. The indication of lateral VDLT intubation should be based on a balance between the safety of airway management and the lower incidence of displacement. TRIAL REGISTRATION: The study was registered at Chictr.org.cn with the number ChiCTR2200064831 on 19/10/2022.

Protocol for a randomised controlled trial: optimisation of perioperative analgesia protocol for uniportal video-assisted thoracoscopic surgery.

INTRODUCTION: Postoperative pain after thoracic surgery impairs patients' quality of life and increases the incidence of respiratory complications. Optimised analgesia strategies include minimally invasive incisions, regional analgesia and early chest tube removal. However, little is known about the optimal analgesic regimen for uniportal video-assisted thoracoscopic surgery (uVATS). METHODS AND ANALYSIS: We will conduct a single-centre, prospective, single-blind, randomised trial. The effects of postoperative analgesia will be tested using thoracic paravertebral block (PVB) in combination with patient-controlled intravenous analgesia (PVB+PCIA), erector spinae plane block (ESPB) in combination with patient-controlled intravenous analgesia (ESPB+PCIA) or PCIA alone; 102 patients undergoing uVATS will be enrolled in this study. Patients will be randomly assigned to the PVB group (30 mL of 0.33% ropivacaine with dexamethasone), ESPB group (40 mL of 0.25% ropivacaine with dexamethasone) or control groups. PCIA with sufentanil will be administered to all patients after surgery. The primary outcome will be total opioid consumption after surgery. Secondary outcomes include postoperative pain score; postoperative chronic pain at rest and during coughing; sensations of touch and pain in the chest wall, non-opioid analgesic consumption; length of stay; ambulation time, the total cost of hospitalisation and long-term postoperative analgesia. Adverse reactions to analgesics and adverse events related to the regional blocks will also be recorded. The statisticians will be blinded to the group allocation. Comparison of the continuous data among the three groups will be performed using a one-way analysis of variance to assess differences among the means. ETHICS AND DISSEMINATION: The results will be published in patient education courses, academic conferences and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT06016777.

Letter to editor : comparison of the surgical outcomes of the posterior approach, video­assisted thoracic surgery, and combined approach for thoracic dumbbell tumors based on a new classification: a retrospective study of published cases.

This critique evaluates a retrospective study comparing surgical outcomes for thoracic dumbbell tumors utilizing different approaches. The study provides comprehensive insights into the management of this complex condition, highlighting the strengths and weaknesses of its methodology and findings. While the study offers valuable information for guiding clinical practice, its retrospective design and inherent limitations warrant careful interpretation of the results. Addressing these limitations through prospective studies with randomized designs and larger patient populations could further enhance our understanding of the optimal surgical approach for thoracic dumbbell tumors.

[Research Progress on Localization of Pulmonary Nodules].

With the widespread adoption of low-dose computed tomography (LDCT) and advancements in computed tomography image resolution, the detection rate of pulmonary nodules, especially smaller ones, has significantly improved. The risk of developing malignant tumors increases with the pulmonary nodule diameter. Video-assisted thoracoscopic surgery (VATS) stands out as the preferred surgical method. The accurate localization of pulmonary nodules is crucial for the success of VATS and remains a significant challenge for thoracic surgeons. Currently, commonly employed localization methods include CT-guided percutaneous positioning, bronchoscope-guided positioning, intraoperative ultrasound positioning, augmented reality (AR), and 3D print-assisted positioning. This review explores recent research progress, highlights the strengths and weaknesses of various pulmonary nodule localization methods. The aim is to provide valuable insights for clinical applications and guide future developments in this field.

[Video-assisted Thoracoscopic Surgery for Chest Trauma].

Video-assisted thoracoscopic surgery (VATS) is now commonly used in emergency surgery to confirm the site of injury and observe the thoracic cavity, especially in cases of chest trauma with stable vital signs. VATS was used in all 33 chest trauma surgeries performed at our department from October 2009 to July 2023. The common injury mechanisms were traffic trauma and falls, but there were also cases of trauma from a bullhorn, heavy machinery and farm equipment, and penetrating injury. The common surgical procedures were treatment of rib fractures and pulmonary suture or partial lung resection, followed by treatment of diaphragmatic injuries. Unusual surgical procedures included extrapleural hematoma drainage, pericardial drainage, hemostasis of intrathoracic bleeding from thoracic vertebral fracture, and lobectomy for airway bleeding. Here, we report our surgical policies and techniques for chest trauma. First, the thoracic cavity should be observed thoracoscopically to determine the site of injury. The key to repair is placement of a small thoracotomy directly above the rib fracture site, where dislocation is largest, followed by suture repair of the lung and diaphragm by combining direct and thoracoscopic views.
