Adoption of Minimally Invasive Lung Resection: A National Cancer Database Study.

INTRODUCTION: Minimally invasive lung resection has been associated with improved outcomes; however, institutional characteristics associated with utilization are unclear. We hypothesized that the presence of surgical robots at institutions would be associated with increased utilization of minimally invasive techniques . METHODS: Patients with cT1/2N0M0 non-small cell lung cancer who underwent lung lobectomy between 2010 and 2020 in the National Cancer Database were identified. Patients were categorized by operative approach as minimally invasive surgery (MIS) versus open. Institutions were categorized as "high utilizers" of MIS technique if their proportion of MIS lobectomies was >50%. Multivariate logistic regressions were used to determine factors associated with proportion of procedures performed minimally invasively. Further multivariate models were used to evaluate the association of proportion of MIS procedures with 90-d mortality, hospital length of stay, and hospital readmission. RESULTS: In multivariate analysis, passage of time by year (odds ratio [OR] 1.26; confidence interval [CI] 1.22-1.30) and presence of a robot at the facility (OR 3.48; CI 2.84-4.24) were associated with high MIS-utilizing facilities. High utilizers of MIS were associated with lower 90-d mortality (OR 0.89; CI 0.83-0.97) and hospital length of stay (coeff -0.88; CI -1.03 to -0.72). Hospital readmission was similar between high and low MIS-utilizing facilities (compared to low MIS-utilizing facilities: OR 1.06; CI 0.95-1.09). CONCLUSIONS: Passage of time and the presence of surgical robots were independently associated with increased utilization of MIS lobectomy. In addition to being associated with improved patient-level outcomes, robotic surgery is correlated with a higher proportion of procedures being performed minimally invasively.

A new vessel filled and heart-beating human corpse model for VATS lobectomy training.

BACKGROUND: Nowadays, video-assisted thoracic surgery (VATS) lobectomy represents the treatment of choice for early-stage lung cancer. Over the years, different methods for VATS training have evolved. The aim of this study is to present an innovative beating-heart filled-vessel cadaveric model to simulate VATS lobectomies. METHODS: Via selective cannulation of the cadaver heart, the pulmonary vessels were filled with a gel to improve their haptic feedback. An endotracheal tube with a balloon on its tip then allowed movement of the heart chambers, transmitting a minimum of flow to the pulmonary vessels. A simulated OR was created, using all instrumentation normally available during surgery on living patients, with trainees constantly mentored by experienced surgeons. At the end of each simulation, the participants were asked 5 questions on a scale of 1 to 10 to evaluate the effectiveness of the training method ("1" being ineffective and "10" being highly effective). RESULTS: Eight models were set up, each with a median time of 108 min and a cost of €1500. Overall, 50 surgeons were involved, of which 39 (78%) were consultants and 11 (22%) were residents (PGY 3-5). The median scores for the 5 questions were 8.5 (Q1; IQR1-3 8-9), 8 (Q2; IQR1-3 7-9), 9 (Q3; IQR1-3 8-10), 9 (Q4; IQR1-3 8-10), and 9 (Q5; IQR1-3 8-10). Overall, the model was most appreciated by young trainees even though positive responses were also provided by senior surgeons. CONCLUSIONS: We introduce a new beating-heart filled-vessel cadaveric model to simulate VATS lobectomies. From this initial experience, the model is cost effective, smooth to develop, and realistic for VATS simulation.

Clinical and biological effects of different energetic surgical devices currently used for mini-invasive anatomical lung resections for the treatment of NSCLC: a prospective interventional study.

BACKGROUND: This study aims to compare three commonly used energy devices for dissection during Video-Assisted Thoracoscopic Surgery (VATS) lobectomy: monopolar hook, advanced bipolar, and ultrasonic device, in terms of duration of the surgical procedure and clinical intra- and post-operative outcomes. MATERIALS AND METHODS: In this prospective single-center study, 75 patients undergoing VATS lobectomy for non-small cell lung cancer between January 2022 and May 2023 were enrolled and divided into 3 groups based on the device used during the surgical procedure (Group 1: Ultrasonic Device, Group 2: Advanced Bipolar, Group 3: Monopolar Hook). The duration of the surgical procedure, daily pleural fluid production, post-operative pain, length of hospital stay, and occurrence of post-operative complications were compared for each group. In a subgroup of 20 patients (10 from Group 1 and 10 from Group 3), concentrations of inflammatory cytokines in pleural fluid at 3 h and 48 h post-surgery were analyzed. RESULTS: Pleural fluid production on the first and second post-operative days was significantly lower in patients treated with the Ultrasonic device compared to the other two groups (p < 0.001). The duration of the surgical procedure was significantly shorter when using the Ultrasonic device (p < 0.001). There were no significant differences in length of hospital stay (p = 0.975), pain on the first and second post-operative days (p = 0.147 and p = 0.755, respectively), and blood hemoglobin levels on the first post-operative day (p = 0.709) and at discharge (p = 0.795). No differences were observed in terms of post-operative complications, although the incidence of post-operative cardiac arrhythmias was borderline significant (p = 0.096), with no cases of arrhythmias recorded in Group 1. IL-10 levels in pleural fluid of patients in Group 3 peaked at 3 h post-surgery, with a significant reduction at 48 h (p = 0.459). DISCUSSION: The use of the ultrasonic device during VATS lobectomy may reduce pleural fluid production and shorten the duration of the surgical procedure compared to using a monopolar hook or advanced bipolar device. The choice of energy device may influence the local inflammatory response, although further studies are needed to confirm these results.

The role of surgery for invasive pulmonary aspergillosis in paediatric hemato-oncology patients-Can we better define it?

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a serious condition with high morbidity and mortality in paediatric patients with cancer, haematological diseases or immunodeficiencies with or without allogeneic haematopoietic stem cell transplantation (HSCT). The role of surgical intervention for the management of IPA has scarcely been investigated. OBJECTIVES: The aim of this study was to present a single center experience of management of IPA in paediatric patients of an oncological ward, to determine the short and long-term outcomes after thoracic surgical interventions, and to outline the indications of surgical interventions in selected patients. PATIENTS/METHODS: We conducted a retrospective study of 44 paediatric patients with proven and probable IPA treated in our institution between January 2003 and December 2021. The primary endpoint was the overall survival after surgical interventions. Secondary endpoints included post-operative morbidity and mortality. RESULTS: The median age at diagnosis of IPA in our cohort was 11.79 years (range 0.11-19.6). The underlying conditions were malignancies in 34 (77%) patients and haematological or immunological disorders with allogeneic HSCT in 9 (23%) patients. We performed thoracic surgical interventions in 10 (22.7%) patients. Most patients received a video assisted thoracic surgery. Only one patient died within 90 days after surgery with a median follow-up time of 50 months. No other major post-operative complications occurred. The calculated 5-year survival rate from IPA for patients after surgical intervention with curative intention was 57% and 56% for patients without (p = .8216). CONCLUSIONS: IPA resulted in relevant morbidity and mortality in our paediatric patient cohort. Thoracic surgical interventions are feasible and may be associated with prolonged survival as a part of multidisciplinary approach in selected paediatric patients with IPA. Larger scale studies are necessary to investigate the variables associated with the necessity of surgery.

Impact of Surgical Positioning on the Occurrence of Postoperative Ipilateral Shoulder Pain After Lung Resection by Video-Assisted Thoracoscopy: A Randomized Trial.

OBJECTIVE: The aim of this study was to evaluate the impact of the ipsilateral arm position on ipsilateral shoulder pain after lung cancer resection by video-assisted thoracic surgery. DESIGN: A prospective randomized controlled trial. SETTING: A single academic center study. PARTICIPANTS: Patients undergoing video-assisted thoracic surgery pulmonary resection for cancer at the Institut Universitaire de Cardiologie et de Pneumologie de Québec from May 2020 to May 2022 were included. INTERVENTIONS: Patients randomly were assigned with a 1:1 ratio to a supported or suspended ipsilateral arm position. MEASUREMENTS AND MAIN RESULTS: Ipsilateral shoulder pain incidence, pain score, and opioid use were recorded in the postanesthesia care unit (PACU) on postoperative days 1 and 2. One hundred thirty-three patients were randomized, 67 in the suspended-arm group and 66 in the supported-arm group. Of the patients, 31% reported ipsilateral shoulder pain in the PACU with no difference between groups (19/67 [28.4%] v 22/66 patients (33.3%), p = 0.5767). There was no significant difference between the pain score in the PACU (3 [0-6] v 4 [0-6], p = 0.9055) at postoperative day 1 (4 [2-6] v 3 [2-5], p = 0.4113) and at postoperative day 2 (2 [0-5] v 2 [1-4], p = 0.9508). Ipsilateral shoulder pain score decreased rapidly on postoperative day 2. There was no statistical difference in opioid and gabapentinoid use between the groups. CONCLUSIONS: Ipsilateral arm position seems to have no impact on ipsilateral shoulder pain.

The role of calcification in predicting invasion of thymoma to adjacent organs.

PURPOSE: Thoracoscopic procedures such as video-assisted thoracoscopic surgery (VATS) and robot-assisted thoracoscopic surgery (RATS) have gained popularity for the treatment of thymoma. Accurate preoperative assessments of tumor invasion are crucial to identifying the appropriate surgical approach. Although imaging techniques have been used to predict invasion, a quantifiable method is still needed in clinical practice. METHODS: The ubjects of this retrospective study were 226 patients with thymoma who underwent surgery at our hospital. Clinicopathological data, tumor staging, and recurrence rates were analyzed. Calcification identified through computed tomography (CT) defined the "calcified group" as having a long diameter of ≥ 5 mm. Statistical analyses were performed to assess relationships and survival outcomes. RESULTS: The calcified group had higher Masaoka and World Health Organization classification than the noncalcified group, with significantly higher organ invasion rates. The calcified group also had remarkably higher recurrence rates. CONCLUSION: Thymoma calcification appears to correlate with increased invasiveness and recurrence rates, suggesting its potential as a predictor of tumor stage and prognosis. Despite its retrospective nature and inherent limitations, this study highlights the potential clinical significance of calcification in the surgical planning and prognostication of patients with thymoma.

Perioperative outcomes of uniportal versus three-port video-assisted thoracoscopic surgery in lung cancer patients aged ≥ 75 years old: a cohort study.

BACKGROUND: Increasing attention has been raised on the surgical option for lung cancer patients aged ≥75 years, however, few studies have focused on whether uniportal video-assisted thoracoscopic surgery (VATS) is safe and feasible for these patients. This study aimed to evaluate short-term results of uniportal versus three-port VATS for the treatment of lung cancer patients aged ≥75 years. METHODS: We retrospectively evaluated 582 lung cancer patients (≥75 years) who underwent uniportal or three-port VATS from August 2007 to August 2021 based on the Western China Lung Cancer Database. The baseline and perioperative outcomes between uniportal and three-port VATS were compared in the whole cohort (WC) and the patients undergoing lobectomy (lobectomy cohort, LC) respectively. Propensity score matching (PSM) was used to minimize confounding bias between the uniportal and three-port cohorts in WC and LC. RESULTS: Intraoperative blood loss was significantly less in the uniportal than three-port LC (50 mL vs. 83 mL, P = 0.007) before PSM and relatively less in the uniportal than three-port LC (50 mL vs. 83 mL, P = 0.05) after PSM. Significantly more lymph nodes harvested (13 vs. 9, P = 0.007) were found in the uniportal than three-port LC after PSM. In addition, in WC and LC, there were no significant differences between uniportal and three-port cohorts in terms of operation time, the rate of conversion to thoracotomy during surgery, nodal treatments (dissection or sampling or not), the overall number of lymph node stations dissected, postoperative complications, volume and duration of postoperative thoracic drainage, hospital stay after operation and hospitalization expenses before and after PSM (P > 0.05). CONCLUSIONS: There were no significant differences in short-term outcomes between uniportal and three-port VATS for lung cancer patients (≥75 years), except relatively less intraoperative blood loss (P < 0.05 before PSM and P = 0.05 after PSM) and significantly more lymph nodes harvested (P < 0.05 after PSM) were found in uniportal LC. It is reasonable to indicate that uniportal VATS is a safe, feasible and effective operation procedure for lung cancer patients aged ≥75 years.

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.

Posterior video-assisted trans pedicular surgery for calcified midline thoracic disc herniation.

BACKGROUND: In the treatment of patients with calcified midline thoracic disc herniation (CMTDH), the posterior video-assisted transpedicular surgery (VATPS) technique is employed. Both anterior and posterior surgical approaches for treating CMTDH carry a significant risk of surgical complications and potential morbidity. This technical note introduces a surgical procedure that avoids the drawbacks associated with these approaches. METHODS: The VATPS technique presents a comprehensive approach for treating thoracic disc herniation, combining both microscopic and endoscopic stages. The microscopic phase entails a small thoracoscopic incision, muscle release, hemilaminotomy, facet joint resection, and vertebra removal, culminating in creating a corpectomy cavity for endoscope access. Careful separation of adhesions between the dura and ligaments marks this stage. Transitioning to the endoscopic phase, an endoscope is inserted into the cavity, allowing for precise visualization and separation of residual adhesions, removal of calcified disc fragments using specialized instruments, and ensuring complete discectomy. RESULTS: Fourteen patients underwent VATPS for CMTDH. During the procedure, evoked responses were reduced in one patient. However, no postoperative neurological deficits were observed. We also noted significant improvements in the Oswestry Disability Index (ODI) and the Visual Analog Scale (VAS) scores when comparing the preoperative and postoperative assessments. CONCLUSION: VATPS, a minimally invasive technique, offers excellent anterior visibility comparable to that of the anterolateral approach, all while avoiding the adverse effects associated with thoracotomies and the complications resulting from spinal cord encroachment often seen in the posterolateral approach. Moreover, it is a safer alternative to conventional endoscopic posterior thoracic surgery. The cavity formed within the vertebral corpus provides ample working space for the use of an endoscope.

A case series: uniportal VATS excision of pericardial cysts in symptomatic patients.

BACKGROUND: Pericardial cysts are infrequent lesions. Most of these are asymptomatic and incidental findings during investigations for unrelated conditions. When they are symptomatic, they demonstrate most of the time a benign clinical course. Yet, treatment is sometimes necessary. Besides a (temporary) treatment as percutaneous aspiration, there is surgery as a definite treatment. The aim of the paper is to motivate the safety and efficacy of uniportal video assisted thoracoscopy (UVATS) for the excision of (giant) pericardial cysts and describe their (peri-)operative technique. METHODS: In this retrospective, single center-based case series, we report all cases with a pericardial cyst who underwent a surgical excision by uniportal VATS (UVATS) between March 2022 and April 2023. Detailed patient characteristics, operation details, hospital length of stay and follow-up data were collected. RESULTS: A total of 4 patients underwent excision of a pericardial cyst by UVATS. The follow-up ranged from 10 to 20 months. The mean diameter of the pericardial cyst was 124 mm. Median procedure time was 94 min. No per- and postoperative complications occurred. The median length of postoperative hospital stay was 2 days. All patients showed a clinically relevant improvement of the pre-operative symptoms. CONCLUSIONS: Uniportal VATS excision for pericardial cysts is a safe and effective surgical procedure with good outcomes on symptom relief. Though, future comparative studies are urged to elucidate its value among other treatment options.

[Differential diagnosis of coccidioidomycosis manifested by peripheral pulmonary lesion]. / Differentsial'naya diagnostika koktsidioidomikoza, manifestirovannogo perifericheskim obrazovaniem legkogo.

We present this clinical case as a demonstration of difficulties in differential diagnosis of pulmonary coccidioidomycosis. Differential diagnostics of peripheral pulmonary lesion performed using bronchoscopy with BAL and TBCB and video-assisted thoracic surgery (VATS) biopsy. Diagnostic specimens were tested using microbiological (luminescent microscopy, culture for M. tuberculosis (BACTEC MGIT960 and Lowenstein-Jensen Medium), RT-PCR, cytological and morphological (hematoxylin-eosin, Ziehl-Neelsen, PAS, Grocott methenamine silver (GMS) stainings) examinations. A diagnosis was verified correctly In Russia the country is not endemic for coccidioidomycosis and patient was treated accordingly. Diagnostics of peripheral pulmonary lesions requires of multidisciplinary approaches. Morphological examination, based on detection of only granulomatous inflammation in lung biopsy cannot be used for finally DS and requires microbiological confirmation for TB or other infections, and dynamic monitoring of the patient with concordance their anamnesis vitae and morbi.

Pathologic Criteria for the Diagnosis of Usual Interstitial Pneumonia vs Fibrotic Hypersensitivity Pneumonitis in Transbronchial Cryobiopsies.

Transbronchial cryobiopsy (TBCB) is increasingly used for the diagnosis of fibrosing interstitial pneumonias, but there are few detailed descriptions of the pathologic findings in such cases. It has been proposed that a combination of patchy fibrosis and fibroblast foci with an absence of alternative features is diagnostic of usual interstitial pneumonia (UIP; ie, idiopathic pulmonary fibrosis [IPF]) in TBCB. In this study, we reviewed 121 TBCB in which a diagnosis of fibrotic hypersensitivity pneumonitis (FHP; n = 83) or IPF (n = 38) was made by multidisciplinary discussion and evaluated a range of pathologic features. Patchy fibrosis was found in 65 of 83 (78%) biopsies from FHP and 32of 38 (84%) biopsies from UIP/IPF cases. Fibroblast foci were present in 47 of 83 (57%) FHP and 27 of 38 (71%) UIP/IPF cases. Fibroblast foci/patchy fibrosis combined did not favor either diagnosis. Architectural distortion was seen in 54 of 83 (65%) FHP and 32 of 38 (84%) UIP/IPF cases (odds ratio [OR] for FHP, 0.35; P = .036) and honeycombing in 18 of 83 (22%) and 17 of 38 (45%), respectively (OR, 0.37; P = .014). Airspace giant cells/granulomas were present in 13 of 83 (20%) FHP and 1 of 38 (2.6%) UIP/IPF cases (OR for FHP, 6.87; P = .068), and interstitial giant cells/granulomas in 20 of 83 (24%) FHP and 0 of 38 (0%) UIP/IPF (OR, 6.7 x 106; P = .000). We conclude that patchy fibrosis plus fibroblast foci can be found in TBCB from both FHP and UIP/IPF. The complete absence of architectural distortion/honeycombing favors a diagnosis of FHP, as does the presence of airspace or interstitial giant cells/granulomas, but these measures are insensitive, and many cases of FHP cannot be separated from UIP/IPF on TBCB.

Extension of lymph node dissection in the surgical treatment of esophageal and gastroesophageal junction cancer: seven questions and answers.

The role of two- or three-field nodal dissection in the surgical treatment of esophageal and gastroesophageal junction cancer in the minimally invasive era is still controversial. This review aims to clarify the extension of nodal dissection in esophageal and gastroesophageal junctional cancer. A basic evidence-based analysis was designed, and seven research questions were formulated and answered with a narrative review. Reports with little or no data, single cases, small series and review articles were not included. Three-field lymph node dissection improves staging accuracy, enhances locoregional disease control and might improve survival in the group of patients with cervical and upper mediastinal metastatic lymph nodal involvement from middle and proximal-third esophageal cancer.

External validation of risk prediction scores in patients undergoing anatomic video-assisted thoracoscopic resection.

BACKGROUND: EuroLung Risk scores were established to predict postoperative morbidity and mortality in patients undergoing anatomic lung resections. We aimed to perform an external validation of the EuroLung scores, which were calculated from data of the European Society of Thoracic Surgeons database, in our video-assisted thoracoscopic surgery cohort. METHODS: All available EuroLung scores were calculated for 718 patients scheduled for anatomic video-assisted thoracoscopic surgery resections between 2009 and 2019. Morbidity and mortality according to the definitions of the EuroLung scores were analyzed in a prospectively maintained database. RESULTS: Overall observed complication rate was 10.45%. Scores showed weak individual correlation (η = 0.155-0.174). The EuroLung1 app score showed the biggest area under the receiver operative characteristic (ROC) curve with 0.660. Binary logistic regression analysis showed that predicted postoperative forced expiratory volume in 1 s was associated with increased complications in both EuroLung1 and parsimonious EuroLung1 scores. Thirty-day mortality was 0.7% (predicted 1.10-1.40%) and was associated with predicted postoperative forced expiratory volume in 1 s for both EuroLung2 and parsimonious EuroLung2 scores. The EuroLung2 (2016) showed the biggest area under the ROC curve with 0.673. Only a very weak eta correlation between predicted and observed mortality was found for both aggregate EuroLung2, EuroLung2 (2016), EuroLung2 (2019), and parsimonious EuroLung2 (2016) (η = 0.025/0.015/0.011/0.009). CONCLUSION: EuroLung scores help to estimate postoperative morbidity. However, even with the highest aggregate EuroLung scores possible only 50% suffer from postoperative morbidity. Although calibration of the scores was acceptable, discrimination between predicted and observed events was poor. Therefore, individual correlation between predicted and observed events is weak. Therefore, EuroLung scores may be best used to compare institutional quality of care to the European Society of Thoracic Surgeons database but should not be used to preclude patients from surgical treatment.

Extrapleural infusion of levobupivacaine versus levobupivacaine-sufentanil-adrenaline after video-assisted thoracoscopic surgery (VATS): A randomised controlled trial.

BACKGROUND: Peripheral blocks are increasingly used for analgesia after video-assisted thoracic surgery (VATS). We hypothesised that addition of sufentanil and adrenaline to levobupivacaine would improve the analgesic effect of a continuous extrapleural block. METHODS: We randomised 60 patients undergoing VATS to a 5-mL h-1 extrapleural infusion of levobupivacaine at 2.7 mg mL-1 (LB group) or levobupivacaine at 1.25 mg mL-1 , sufentanil at 0.5 µg mL-1 , and adrenaline at 2 µg mL-1 (LBSA group). The primary outcome was the cumulative morphine dose administered as patient-controlled analgesia (PCA-morphine) at 48 and 72 h. The secondary outcomes were pain according to numerical rating scale (NRS) at rest and after two deep breaths twice daily, peak expiratory flow (PEF) daily, quality of recovery (QoR)-15 score at 1 day and 3 weeks postoperatively, serum levobupivacaine concentrations at 1 h after the start and at the end of the intervention, and adverse events. RESULTS: At 48 h, the median cumulative PCA-morphine dose for the LB group was 6 mg (IQR, 2-10 mg) and for the LBSA group 7 mg (IQR, 3-13.5 mg; p = .378). At 72 h, morphine doses were 10 mg (IQR, 3-22 mg) and 12.5 mg (IQR, 4-21 mg; p = .738), respectively. Median NRS score at rest and after two deep breaths was 3 or lower at all time points for both treatment groups. PEF did not differ between groups. Three weeks postoperatively, only the LB group returned to baseline QoR-15 score. The LB group had higher, but well below toxic, levobupivacaine concentrations at 48 and 72 h. The incidence of nausea, dizziness, pruritus and headache was equally low overall. CONCLUSION: For a continuous extrapleural block, and compared to plain levobupivacaine at 13.5 mg h-1 , levobupivacaine at 6.25 mg h-1 with addition of sufentanil and adrenaline did not decrease postoperative morphine consumption. The levobupivacaine serum concentrations after 48 and 72 h of infusion were well below toxic levels, therefore our findings support the use of the maximally recommended dose of levobupivacaine for a 2- to 3-day continuous extrapleural block.

Is VATS suitable for lung diseases with hemoptysis? Experience from a hemoptysis treatment center in China.

BACKGROUND: Surgery is crucial in the treatment of the potentially fatal pulmonary hemoptysis condition. Currently, most patients with hemoptysis are treated by traditional open surgery (OS). To illustrate the effectiveness of video-assisted thoracic surgery (VATS) for hemoptysis, we developed a retrospective study of surgical interventions for lung disease with hemoptysis. METHODS: We collected and then analysed the data, including general information and post-operative outcomes, from 102 patients who underwent surgery for a variety of lung diseases with hemoptysis in our hospital between December 2018 and June 2022. RESULTS: Sixty three cases underwent VATS and 39 cases underwent OS. 76.5% of patients were male (78/102). Comorbidities with diabetes and hypertension were 16.7% (17/102) and 15.7% (16/102) respectively. The diagnoses based on postoperative pathology included aspergilloma in 63 cases (61.8%), tuberculosis in 38 cases (37.4%) and bronchiectasis in 1 case (0.8%). 8 patients underwent wedge resection, 12 patients underwent segmentectomy, 73 patients underwent lobectomy and 9 patients underwent pneumonectomy. There were 23 cases of postoperative complications, of which 7 (30.4%) were in the VATS group, significantly fewer than 16 (69.6%) in the OS group (p = 0.001). The OS procedure was identified as the only independent risk factor for postoperative complications. The median (IQR) of postoperative drainage volume in the first 24 h was 400 (195-665) ml, which was 250 (130-500) ml of the VATS group, significantly less than the 550 (460-820) ml of the OS group (p < 0.05). The median (IQR) of pain scores 24 h after surgery was 5 (4-9). The median (IQR) of postoperative drainage tube removal time was 9.5 (6-17) days for all patients, and it was 7 (5-14) days for the VATS group, which was less than 15 (9-20) days for the OS group. CONCLUSION: VATS for patients with lung disease presenting with hemoptysis is an effective and safe option that may be preferred when the hemoptysis is uncomplicated and the patient's vital signs are stable.

Regional Anesthesia for Lobectomy and Risk of Pulmonary Complications: A National Safety Quality Improvement Program Propensity-Matching Analysis.

OBJECTIVE: To determine whether general anesthesia (GA) in conjunction with regional anesthetic (RA) techniques are associated with favorable pulmonary outcomes versus GA alone among patients undergoing lobectomy by either video-assisted thoracoscopic surgery (VATS) or open thoracotomy. DESIGN: A retrospective cohort (2014-2017). SETTING: The American College of Surgeons National Surgical Quality Improvement Program. PARTICIPANTS: Adult patients undergoing lobectomy by either VATS or open thoracotomy. INTERVENTIONS: Two groups of patients were identified based on the use of GA alone or GA in conjunction with RA (RA+GA) techniques (either neuraxial or peripheral nerve blocks). Both groups were propensity-matched based on pulmonary risk factors. The authors' primary outcome was composite postoperative pulmonary complication (PPC), including pneumonia, reintubation, and failure to wean from the ventilator. MEASUREMENTS AND MAIN RESULTS: A total of 4,134 VATS (2,067 in GA and 2,067 in RA+GA) and 3,112 thoracotomies (1,556 in GA and 1,556 in RA+GA) were included in the final analysis. Regional anesthetic, as an adjuvant to GA, did not affect the incidence of PPC among patients undergoing lobectomy by VATS (odds ratio [OR] 1.07, 95% CI 0.81-1.43, p = 0.622), as well as in those undergoing lobectomy via thoracotomy (OR 1.19, 95% CI 0.93-1.51, p = 0.174). There was no statistically significant difference between groups in terms of readmission rates, length of stay, and mortality at 30 days. CONCLUSIONS: The RA techniques were not associated with a lower incidence of pulmonary complications in lobectomy surgery.

Anesthesia for Nonintubated Video-Assisted Thoracoscopic Surgery.

With the growing adoption of Enhanced Recovery After Surgery protocols across all surgical groups, including thoracic surgery, coupled with improved video-assisted thoracoscopic surgery (VATS) equipment and techniques, nonintubated thoracoscopic surgery has gained significant popularity in recent years. Avoiding tracheal intubation with an endotracheal or double-lumen tube and general anesthesia may reduce or eliminate the risks associated with traditional mechanical ventilation, one-lung ventilation, and general anesthesia. Studies have shown a trend toward better preservation of postoperative respiratory function and improved postoperative lengths of hospital stay, morbidity, and mortality; however, these have not been conclusively proven. This review article discusses the advantages of nonintubated VATS, the types of thoracic surgery in which this technique has been described, patient selection, appropriate anesthetic techniques, surgical concerns, potential complications relevant to the anesthesiologist during the conduct of nonintubated VATS surgery, and suggested management of these complications.

A Single Preoperative Dose of S-Ketamine Has No Beneficial Effect on Chronic Postsurgical Pain in Patients Undergoing Video-Assisted Thoracoscopic Surgical Lung Lesion Resection: A Prospective Randomized Controlled Study.

OBJECTIVES: To evaluate the efficacy of a single preoperative dose of S-ketamine for chronic postsurgical pain (CPSP) in patients undergoing video-assisted thoracoscopic surgical lung lesion resection (VATS). DESIGN: A prospective randomized, double-blind controlled study. SETTING: Patients were enrolled from March 17, 2021, to November 18, 2021, at a single tertiary academic hospital. PARTICIPANTS: Patients were 18-to-65 years of age and undergoing VATS. INTERVENTIONS: The experiment was divided into an S-ketamine group (0.5 mg/kg intravenous injection before anesthesia induction) or a placebo group (the same volume of normal saline). MEASUREMENTS AND MAIN RESULTS: The primary endpoint was the incidence of CPSP and its neuropathic component. The secondary endpoints included acute postoperative pain, the use of postoperative analgesics, anxiety and sleep quality scores, and the occurrence of adverse effects. There were no significant differences between the 2 groups in the incidences of CPSP, neuropathic pain, acute postoperative pain, and postoperative use of analgesics. The sleep quality scores on the first postoperative day differed significantly between the groups (47.45 ± 27.58 v . 52.97 ± 27.57, p = 0.049), but not the anxiety scores. In addition, adverse effects were similar between the 2 groups. CONCLUSIONS: A single preoperative dose of S-ketamine in patients who underwent VATS had no significant effect on acute and chronic postoperative pain or the consumption of analgesics after surgery. A single preoperative dose of S-ketamine could improve sleep on the first day after surgery, whereas it had no significant effect on anxiety levels.

Uniportal versus multiportal video-assisted thoracoscopic segmentectomy for non-small cell lung cancer: a systematic review and meta-analysis.

It remains controversial whether one-port video-assisted thoracoscopic surgery (VATS) or multiportal VATS is better for segmentectomy in patients with early non-small cell lung cancer (NSCLC). We conducted this meta-analysis of eight published studies to compare the clinical effectiveness and safety of the two surgical approaches. The uniportal group had a shorter postoperative hospital stay (mean difference (MD): - 0.40, 95% CI [- 0.71 to - 0.08] days, p = 0.01), lower postoperative pain scores on day 3 (MD: - 0.90, 95% CI [- 1.26 to - 0.54], p < 0.00001) and day 7 (MD: - 0.33, 95% CI [- 0.62 to - 0.04], p = 0.02), fewer days of chest tube drainage (MD: - 0.47, 95% CI [- 0.78 to - 0.15] days, p = 0.004), and a smaller wound (MD: - 0.73, 95% CI [- 1.00 to - 0.46] cm, p < 0.00001) than the multiportal group. However, there were no significant differences between the groups in complications, operative times, resected lymph nodes, resected lymph node stations, blood loss, postoperative pain scores on days 1, 2, 30, overall survival (OS), or disease-free survival (DFS). The most common complications were prolonged air leakage (10.29%), bleeding (8.82%), vascular injury (7.14%), empyema (5.88%), and arrhythmia (5.26%) in the uniportal group. Overall, uniportal VATS appears to be better than multiportal VATS for segmentectomy in patients with NSCLC, with better postoperative outcomes and similar survival rates.
