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.

Unveiling the protective role of sevoflurane in video-assisted thoracoscopic surgery associated-acute lung injury: Inhibition of ferroptosis.

Acute lung injury (ALI) frequently occurs after video-assisted thoracoscopic surgery (VATS). Ferroptosis is implicated in several lung diseases. Therefore, the disparate effects and underlying mechanisms of the two commonly used anesthetics (sevoflurane (Sev) and propofol) on VATS-induced ALI need to be clarified. In the present study, enrolled patients were randomly allocated to receive Sev (group S) or propofol anesthesia (group P). Intraoperative oxygenation, morphology of the lung tissue, expression of ZO-1, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), superoxide dismutase (SOD), glutathione (GSH), Fe2+, glutathione peroxidase 4 (GPX4), and phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/nuclear factor erythroid-2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway in the lung tissue as well as the expression of TNF-α and IL-6 in plasma were measured. Postoperative complications were recorded. Of the 85 initially screened patients scheduled for VATS, 62 were enrolled in either group S (n = 32) or P (n = 30). Compared with propofol, Sev substantially (1) improved intraoperative oxygenation; (2) relieved histopathological lung injury; (3) increased ZO-1 protein expression; (4) decreased the levels of TNF-α and IL-6 in both the lung tissue and plasma; (5) increased the contents of GSH and SOD but decreased Fe2+ concentration; (6) upregulated the protein expression of p-AKT, Nrf2, HO-1, and GPX4. No significant differences in the occurrence of postoperative outcomes were observed between both groups. In summary, Sev treatment, in comparison to propofol anesthesia, may suppress local lung and systemic inflammatory responses by activating the PI3K/Akt/Nrf2/HO-1 pathway and inhibiting ferroptosis. This cascade of effects contributes to the maintenance of pulmonary epithelial barrier permeability, alleviation of pulmonary injury, and enhancement of intraoperative oxygenation in patients undergoing VATS.

Periareolar approach in video-assisted thoracoscopic surgery for right middle lobectomy: a novel technique.

BACKGROUND: Uniportal thoracoscopic right middle lobectomy (RML) poses greater technical challenges than other lobectomies. Although two-port thoracoscopy offers convenience, it results in heightened surgical trauma and scarring. The periareolar incision is rarely used in lobectomy while known for its cosmetic advantages. This study presents the periareolar access (combining a periareolar port and a 1-cm port) for video-assisted thoracoscopic surgery (VATS) in RML, comparing it with the traditional uniportal technique in both male and female patients. METHODS: Eighty patients who underwent RML were randomly divided into two groups: the periareolar VATS (PV) approach (n = 40) and the uniportal VATS (UV) approach (n = 40) from August 2020 to February 2023. All patients were followed up for 1 year and clinical data were collected and analyzed. RESULTS: No significant differences in complications, blood loss, duration of chest tube placement, and length of postoperative hospital stay were observed between two methods. However, the PV group exhibited significantly shorter operative time, reduced postoperative visible scarring and lower visual analogue scores (VAS) for postoperative pain (P < 0.05). Additionally, the PV group demonstrated significantly higher cosmetic and satisfaction scores at the 6-month postoperative assessment (P < 0.05). Notably, breast ultrasound follow-up revealed two cases injuries of the mammary glands in female patients, and sensory function of most nipple and areola remained intact except two cases in all PV group patients. CONCLUSIONS: Periareolar VATS emerges as a promising alternative approach for RML, providing clear benefits in pain management and cosmetic outcomes, while maintaining safety and convenience.

Risk factors for diaphragmatic injury in subxiphoid video-assisted thoracoscopic surgery.

BACKGROUND: Subxiphoid video-assisted thoracoscopic surgery (VATS) is considered a safe and feasible operation for anterior mediastinal mass resection. However, diaphragmatic injury, presented as tearing or puncturing, may occur during subxiphoid VATS despite of low incidence. This study aims to explore risk factors for diaphragmatic injury in subxiphoid VATS, as well as strategies to reduce occurrence of the injury. METHODS: We retrospectively reviewed clinical records of 44 consecutive adult patients who underwent subxiphoid VATS. These patients were divided into two groups: diaphragmatic injury group and non-injury group. Perioperative outcomes and anatomic features derived from 3D CT reconstructions were compared between the two groups. RESULTS: Significant differences were observed in operation time (223.25 ± 92.57 vs. 136.28 ± 53.05, P = 0.006), xiphoid length (6.47 ± 0.85 vs. 4.79 ± 1.04, P = 0.001) and length of the xiphoid below the attachment point on the diaphragm (24.86 ± 12.02 vs. 14.61 ± 9.25, P = 0.029). Odds ratio for the length of the xiphoid below the attachment point on the diaphragm was 1.09 (1.001-1.186), P = 0.048 by binary logistic regression analysis. CONCLUSIONS: We identified the length of the xiphoid below the attachment point on the diaphragm as an independent risk factor for diaphragm injury during subxiphoid VATS. Prior to subxiphoid VATS, a 3D chest CT reconstruction is recommended to assess the patients' anatomic variations within the xiphoid process. For patients with longer xiphoid process, a higher incision at the middle and upper part of the xiphoid process, and partial xiphoid process resection or xiphoidectomy is preferred.

Reasons for conversions in thoracoscopic repairs of neonatal congenital diaphragmatic hernias: a systematic review.

PURPOSE: This systematic review focused on reasons for conversions in neonates undergoing thoracoscopic congenital diaphragmatic hernia (CDH) repair. METHODS: Systematic search of Medline/Pubmed and Embase was performed for English, Spanish and Portuguese reports, according to PRISMA guidelines. RESULTS: Of the 153 articles identified (2003-2023), 28 met the inclusion criteria and offered 698 neonates for analysis. Mean birth weight and gestational age were 3109 g and 38.3 weeks, respectively, and neonates were operated at a mean age of 6.12 days. There were 278 males (61.50%; 278/452) and 174 females (38.50%; 174/452). The reasons for the 137 conversions (19.63%) were: (a) defect size (n = 22), (b) need for patch (n = 21); (c) difficulty in reducing organs (n = 14), (d) ventilation issues (n = 10), (e) bleeding, organ injury, cardiovascular instability (n = 3 each), (f) bowel ischemia and defect position (n = 2 each), hepatopulmonary fusion (n = 1), and (g) reason was not specified for n = 56 neonates (40.8%). The repair was primary in 322 neonates (63.1%; 322/510) and patch was used in 188 neonates (36.86%; 188/510). There were 80 recurrences (12.16%; 80/658) and 14 deaths (2.48%; 14/565). Mean LOS and follow-up were 20.17 days and 19.28 months, respectively. CONCLUSIONS: Neonatal thoracoscopic repair for CDH is associated with conversion in 20% of cases. Based on available data, defect size and patch repairs have been identified as the predominant reasons, followed by technical difficulties to reduce the herniated organs and ventilation related issues. However, data specifically relating to conversion is poorly documented in a high number of reports (40%). Accurate data reporting in future will be important to better estimate and quantify reasons for conversions in neonatal thoracoscopy for CDH.

Postoperative outcomes in patients with diabetes after enhanced recovery thoracoscopic lobectomy.

BACKGROUND: Diabetes is considered a general surgical risk factor, but with few data from enhanced recovery (ERAS) otherwise known to improve outcome. Therefore, this study aimed to investigate postoperative outcomes of patients with diabetes who underwent video-assisted thoracoscopic surgery (VATS) lobectomy in an established ERAS setting. METHODS: We retrospectively analysed outcome data (hospital stay (LOS), readmissions, and mortality) from a prospective database with consecutive unselected ERAS VATS lobectomies from 2012 to 2022. Complete follow-up was secured by the registration system in East Denmark. RESULTS: We included 3164 patients of which 323 had diabetes, including 186 treated with insulin and antidiabetic medicine, 35 with insulin only and 102 with antidiabetic medicine only. The median LOS was 3 days, stable over the study period. There were no differences in terms of LOS, postoperative complications, readmissions or 30 days alive and out of hospital. Patients with diabetes had significantly higher 30- and 90-day mortality rates compared to those without diabetes (p < .001), but also had higher preoperative comorbidity. Preoperative HbA1c levels did not correlate with postoperative outcomes. CONCLUSION: In an ERAS setting, diabetes may not increase the risk for prolonged LOS, complications, and readmissions after VATS lobectomy, however with higher 30- and 90-day mortality probably related to more preoperative comorbidities.

Readmission after enhanced recovery video-assisted thoracoscopic surgery wedge resection.

BACKGROUND: Despite the implementation of Enhanced Recovery After Surgery (ERAS) programs, surgical stress continues to influence postoperative rehabilitation, including the period after discharge. However, there is a lack of data available beyond the point of discharge following video-assisted thoracoscopic surgery (VATS) wedge resection. Therefore, the objective of this study is to investigate incidence and risk factors for readmissions after ERAS VATS wedge resection. METHODS: A retrospective analysis was performed on data from prospectively collected consecutive VATS wedge resections from June 2019 to June 2022. We evaluated main reasons related to wedge resection leading to 90-day readmission, early (occurring within 0-30 days postoperatively) and late readmission (occurring within 31-90 days postoperatively). To identify predictors for these readmissions, we utilized a logistic regression model for both univariable and multivariable analyses. RESULTS: A total of 850 patients (non-small cell lung cancer 21.5%, metastasis 44.7%, benign 31.9%, and other lung cancers 1.9%) were included for the final analysis. Median length of stay was 1 day (IQR 1-2). During the postoperative 90 days, 86 patients (10.1%) were readmitted mostly due to pneumonia and pneumothorax. Among the cohort, 66 patients (7.8%) had early readmissions primarily due to pneumothorax and pneumonia, while 27 patients (3.2%) experienced late readmissions mainly due to pneumonia, with 7 (0.8%) patients experiencing both early and late readmissions. Multivariable analysis demonstrated that male gender, pulmonary complications, and neurological complications were associated with readmission. CONCLUSIONS: Readmission after VATS wedge resection remains significant despite an optimal ERAS program, with pneumonia and pneumothorax as the dominant reasons. Early readmission was primarily associated with pneumothorax and pneumonia, while late readmission correlated mainly with pneumonia.

Late video-assisted thoracoscopic surgery versus thoracostomy tube reinsertion for retained hemothorax after penetrating trauma, a prospective randomized control study.

BACKGROUND: Early video-assisted thoracoscopic surgery (VATS) is the recommended treatment of choice for retained hemothorax (RH). A prospective single-center randomized control study was conducted to compare outcomes between VATS and thoracostomy tube (TT) reinsertion for patients with RH after penetrating trauma in a resource constrained unit. Our hypothesis was that patients with a RH receiving VATS instead of TT reinsertion would have a shorter hospital stay and lesser complications. MATERIALS AND METHODS: From January 2014 to November 2019, stable patients with thoracic penetrating trauma complicated with retained hemothoraces were randomized to either VATS or TT reinsertion. The outcomes were length of hospital stay (LOS) and complications. RESULTS: Out of the 77 patients assessed for eligibility, 65 patients were randomized and 62 analyzed: 30 in the VATS arm and 32 in the TT reinsertion arm. Demographics and mechanisms of injury were comparable between the two arms. Length of hospital stay was: preprocedure: VATS 6.8 (+/-2.8) days and TT 6.6 (+/- 2.4) days (p = 0.932) and postprocedure: VATS 5.1 (+/-2.3) days, TT 7.1 (+/-6.3) days (p = 0.459), total LOS VATS 12 (+/- 3.9) days, and TT 14.4 (+/-7) days (p = 0.224). The TT arm had 15 complications compared to the VATS arm of four (p = 0.004). There were two additional procedures in the VATS arm and 10 in the TT arm (p = 0.014). CONCLUSION: VATS proved to be the better treatment modality for RH with fewer complications and less need of additional procedures, while the LOS between the two groups was not statistically different.

Effect of lung isolation with different airway devices on postoperative pneumonia in patients undergoing video-assisted thoracoscopic surgery: a propensity score-matched study.

BACKGROUND: Postoperative pneumonia is one of the common complications after video-assisted thoracoscopic surgery. There is no related study on the effect of lung isolation with different airway devices on postoperative pneumonia. Therefore, in this study, the propensity score matching method was used to retrospectively explore the effects of different lung isolation methods on postoperative pneumonia in patients undergoing video-assisted thoracoscopic surgery. METHODS: This is A single-center, retrospective, propensity score-matched study. The information of patients who underwent VATS in Weifang People 's Hospital from January 2020 to January 2021 was retrospectively included. The patients were divided into three groups according to the airway device used in thoracoscopic surgery: laryngeal mask combined with bronchial blocker group (LM + BB group), tracheal tube combined with bronchial blocker group (TT + BB group) and double-lumen endobronchial tube group (DLT group). The main outcome was the incidence of pneumonia within 7 days after surgery; the secondary outcome were hospitalization time and hospitalization expenses. Patients in the three groups were matched using propensity score matching (PSM) analysis. RESULTS: After propensity score matching analysis, there was no significant difference in the incidence of postoperative pneumonia and hospitalization time among the three groups (P > 0.05), but there was significant difference in hospitalization expenses among the three groups (P < 0.05). CONCLUSIONS: There was no significant difference in the effect of different intubation lung isolation methods on postoperative pneumonia in patients undergoing thoracoscopic surgery.

Nonintubated spontaneous ventilation versus intubated mechanical ventilation anesthesia for video-assisted thoracic surgery in terms of perioperative complications and practitioners' workload assessments: a pilot randomized control study.

BACKGROUND: The use of nonintubated video-assisted thoracoscopic surgery (NI-VATS) has been increasingly reported to yield favourable outcomes. However, this technology has not been routinely used because its advantages and safety have not been fully confirmed. The aim of this study was to assess the safety and feasibility of nonintubated spontaneous ventilation (NI-SV) anesthesia compared to intubated mechanical ventilation (I-MV) anesthesia in VATS by evaluating of perioperative complications and practitioners' workloads. METHODS: Patients who underwent uniportal VATS were randomly assigned at a 1:1 ratio to receive NI-SV or I-MV anesthesia. The primary outcome was the occurrence of intraoperative airway intervention events, including transient MV, conversion to intubation and repositioning of the double-lumen tube. The secondary outcomes included perioperative complications and modified National Aeronautics and Space Administration Task Load Index (NASA-TLX) scores from anesthesiologists and surgeons. RESULTS: Thirty-five patients in each group were enrolled in the intention-to-treat analysis. The incidence of intraoperative airway intervention events was greater in the NI-SV group than in the I-MV group (12 [34.3%] vs. 3 [8.6%]; OR = 0.180; 95% CI = 0.045-0.710; p = 0.009). No significant difference was found in the postoperative pulmonary complications between the groups (p > 0.05). The median of the anesthesiologists' overall NASA-TLX score was 37.5 (29-52) when administering the NI-SV, which was greater than the 25 (19-34.5) when the I-MV was administered (p < 0.001). The surgeons' overall NASA-TLX score was comparable between the two ventilation strategies (28 [21-38.5] vs. 27 [20.5-38.5], p = 0.814). CONCLUSION: The NI-SV anesthesia was feasible for VATS in the selected patients, with a greater incidence of intraoperative airway intervention events than I-MV anesthesia, and with more surgical effort required by anesthesiologists.

Efficacy of postoperative analgesia with intravenous paracetamol and mannitol injection, combined with thoracic paravertebral nerve block in post video-assisted thoracoscopic surgery pain: a prospective, randomized, double-blind controlled trial.

BACKGROUND: Although video-assisted thoracoscopic surgery (VATS) has advantages of reduced injury and faster healing, patients still endure moderate and severe postoperative pain. Paracetamol and mannitol injection, the first acetaminophen injection in China, has the advantages of convenient administration, rapid onset of action, and no first-pass effect. This aim of this study was to investigate the efficacy of postoperative analgesia with paracetamol and mannitol injection, combined with thoracic paravertebral nerve block (TPVB) in post VATS pain. METHODS: This study was a single-center, prospective, randomized, double-blind controlled clinical trial. Patients scheduled for VATS were randomly divided into three groups, general anesthesia group (Group C), TPVB group (Group T) and TPVB + paracetamol and mannitol injection group (Group TP). In this study, the primary outcome was determined as visual analog scale (VAS) scores at rest and coughing, the secondary observation outcomes were the first time to use analgesic pump, the total consumption of oxycodone in the analgesic pump, number of effective and total analgesic pump compressions at first 48 h postoperatively, the perioperative consumption of sufentanil, time to extubation, hospital length of stay, urine volume, and the incidence of adverse events. RESULTS: In a state of rest and cough, patients in the Group TP showed significantly lower VAS pain scores at 1, 12, 24, and 48 postoperative-hour compared with Group C and Group T. Intraoperative sufentanil and postoperative oxycodone consumption, the first time to press analgesic pump, the times of effective and total compressions of patient- controlled analgesia (PCA) were lower than those of the Group C and Group T. Interestingly, urine output was higher in Group TP. There were no differences between the three groups in terms of extubation time, length of hospital stay and adverse effects, indicating that intravenous paracetamol and mannitol injection is an effective and safe perioperative analgesia method. CONCLUSIONS: Paracetamol and mannitol injection, combined with TPVB may provide important beneficial effects on acute pain control and reduce the consumption of opioid in patients undergoing VATS. TRIAL REGISTRATION: The trial was registered on Jun 19, 2023 in the Chinese Clinical Trial Registry ( https://www.chictr.org.cn/showproj.html?proj=199315 ), registration number ChiCTR2300072623 (19/06/2023).

Erector spinae plane block did not improve postoperative pain-related outcomes and recovery after video-assisted thoracoscopic surgery : a randomised controlled double-blinded multi-center trial.

INTRODUCTION: There is a sizable niche for a minimally invasive analgesic technique that could facilitate ambulatory video-assisted thoracoscopic surgery (VATS). Our study aimed to determine the analgesic potential of a single-shot erector spinae plane (ESP) block for VATS. The primary objective was the total hydromorphone consumption with patient-controlled analgesia (PCA) 24 h after surgery. METHODS: We conducted a randomized, controlled, double-blind study with patients scheduled for VATS in two major university-affiliated hospital centres. We randomized 52 patients into two groups: a single-shot ESP block using bupivacaine or an ESP block with normal saline (control). We administered a preoperative and postoperative (24 h) quality of recovery (QoR-15) questionnaire and assessed postoperative pain using a verbal numerical rating scale (VNRS) score. We evaluated the total standardized intraoperative fentanyl administration, total postoperative hydromorphone consumption (PCA; primary endpoint), and the incidence of adverse effects. RESULTS: There was no difference in the primary objective, hydromorphone consumption at 24 h (7.6 (4.4) mg for the Bupivacaine group versus 8.1 (4.2) mg for the Control group). Secondary objectives and incidence of adverse events were not different between the two groups at any time during the first 24 h following surgery. CONCLUSION: Our multi-centre randomized, controlled, double-blinded study found no advantage of an ESP block over placebo for VATS for opioid consumption, pain, or QoR-15 scores. Further studies are ongoing to establish the benefits of using a denser block (single-shot paravertebral with a continuous ESP block), which may provide a better quality of analgesia.

Comparison of the effect between cefazolin/cefuroxime and broad-spectrum antibiotics in preventing post-operative pulmonary infections for smoking patients receiving video-assisted thoracoscopic lung surgery: a propensity score-matched retrospective cohort study.

BACKGROUND: The selection of prophylactic antibiotics for preventing post-operative pulmonary infections in smoking patients undergoing video-assisted thoracoscopic lung surgery (VATLS) is not clear. METHODS: In this retrospective cohort study, the outcomes of 572 smoking patients undergoing VATLS with prophylactic cefazolin/cefuroxime or other antibiotics were analyzed. Patients were classified as cefazolin/cefuroxime group and the control group. A 1:1 propensity score matching was also performed. RESULTS: The primary outcome of the incidence of post-operative pulmonary infection did not differ significantly between the two groups (23.7% vs 30.5%, RR = 0.777, 95%CI 0.564 ~ 1.070 p = 0.113). Similarly, secondary outcomes including the incidence of post-operative fever, the white blood cell count and neutrophils on the 3rd day after the surgery, and time for blood routine test recovery were all found without significant difference between the two groups. In the multivariate logistic regression model, no association was found between prophylactic use of cefazolin/cefuroxime and post-operative pulmonary infections after controlling other possible confounding factors (OR = 0.685, 95%CI 0.441 ~ 1.065, p = 0.093). CONCLUSIONS: Prophylactic use of cefazolin/cefuroxime was not associated with more adverse clinical outcomes among smoking populations undergoing VATLS when compared with broad-spectrum antibiotics and the two drugs are still feasible for peri-operative prophylactic use for smoking population before the surgery.

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.

Ultrasound-guided versus conventional lung recruitment manoeuvres in thoracic surgery: a randomised controlled study.

Lung recruitment manoeuvres (RMs) during mechanical ventilation may reduce atelectasis, however, the optimal recruitment strategy for patients undergoing thoracic surgery remains unknown. Our study was designed to investigate whether ultrasound-guided lung RMs is superior to conventional RMs in reducing perioperative atelectasis during thoracic surgery with one-lung ventilation. We conducted a randomised controlled clinical trial from August 2022 to September 2022. Sixty patients scheduled for video-assisted thoracoscopic surgery (VATS) under general anaesthesia were enrolled. Subjects were randomly divided into the ultrasound-guided RMs group (manual inflation guided by lung ultrasound) or conventional RMs group (manual inflation with 30 cmH2O pressure). Lung ultrasound were performed at three predefined time points (1 min after anaesthetic induction; after RMs at the end of surgery; before discharge from postanesthesia care unit [PACU]). The primary outcome was lung ultrasound score before discharge from the PACU after extubation. In the early postoperative period, lung aeration deteriorated in both groups even after lung RMs. However, ultrasound-guided lung RMs had significantly lower lung ultrasound scores when compared with conventional RMs in bilateral lungs (2.0 [0.8-4.0] vs. 8.0 [3.8-10.3], P < 0.01) at the end of surgery, which remained before patients discharged from the PACU. Accordingly, the lower incidence of atelectasis was found in ultrasound-guided RMs group than in conventional RMs group (7% vs. 53%; P < 0.01) at the end of surgery. Ultrasound-guided RMs is superior to conventional RMs in improving lung aeration and reducing the incidence of lung atelectasis at early postoperative period in patients undergoing VATS. The study protocol was approved by the Institutional Review Board of the Fudan University Shanghai Cancer Center (No. 220,825,810; date of approval: August 5, 2022) and registered on Chinese Clinical Trial Registry (registration number: ChiCTR2200062761).

Pulmonary presentation and coil marcation of dirofilaria lung coin nodes - case report.

Clinicians face significant diagnostic challenges when dealing with nodal lesions of the lung. The majority of lung nodules are benign; however, a significant number can be cancerous. Dirofilaria infestation should also be considered in the differential diagnosis of nodal lung lesions. Most patients with Dirofilaria infestation are asymptomatic. To determine the etiology of nodal lung infiltrations, procedures like radiological imaging, bronchoscopy, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA), transthoracic biopsy (TTB), tumor markers, nonspecific serological tests, or surgical removal of the lung coin lesions can be performed. Coil marking of the smaller lung lesions under computed tomography (CT) guidance is a helpful tool in determining the position and localization of the nodal lung lesions. Video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS) wedge resection is a diagnostic and therapeutic method of choice. No additional treatment of Dirofilaria other than wedge resection of the lung is necessary.

The impact of paravertebral nerve blockade on postoperative surgical site wound pain management in patients undergoing video-assisted thoracoscopic surgery for pulmonary carcinoma resection.

Management of postoperative pain is of vital importance for patients undergoing Video-Assisted Thoracoscopic Surgery (VATS) for Pulmonary Carcinoma Resection. The study evaluates the impact of Paravertebral Nerve Blockade (PNB) in conjunction with general anaesthesia on postoperative pain relief, as compared with general anaesthesia alone. A retrospective analysis was carried out from May 2020 to May 2023, involving 100 patients with pathologically confirmed pulmonary carcinoma. The patients were divided into two groups: a control group that received general anaesthesia and an observation group that received a combination of general anaesthesia and PNB. The intensity of postoperative pain was assessed at various time intervals using the visual analogue scale (VAS), while the effectiveness of patient-controlled analgesia was also evaluated. Additionally, the study examined the incidence rates of chronic pain in the postoperative period. Statistical analysis was performed using IBM SPSS version 27.0. Significant reductions in VAS scores for both resting and cough-induced pain were observed in the observation group at 2 and 6 h post-operation (p < 0.01). However, the difference diminished over time. The observation group had fewer patient-controlled analgesia activations and required lower dosages of hydromorphone at both 24- and 48-h post-operation. The incidence of chronic pain was also significantly lower in the observation group (24.00%) compared with the control group (54.00%) (p < 0.01). PNB, when administered in combination with general anaesthesia, significantly reduces immediate postoperative pain and the requirement for additional analgesics in patients undergoing VATS for pulmonary carcinoma resection. The effect diminishes over time but has a lasting impact on reducing the incidence of chronic postoperative pain.

Efficacy of uniportal versus multiportal video-assisted thoracoscopic lobectomy for non-small cell lung cancer: A retrospective analysis.

Objective: To compare the uniportal and multiportal video-assisted thoracoscopic surgery (VATS) in patients with non-small-cell lung cancer (NSCLC). Methods: Medical records of 128 patients with NSCLC who underwent surgical treatment in the First School of Clinical Medicine, Southern Medical University from August 2020 to February 2022 were retrospectively analyzed. There were 60 patients who underwent uniportal VATS (UVATS group) and 68 patients underwent multiportal VATS (MVATS group). The relevant indexes, complications, postoperative pain levels and quality of life, recurrence, metastases and survival between the two groups were compared. Results: UVATS was associated with longer operation time and higher intraoperative blood loss compared to MVATS (P<0.05). The postoperative drainage volume, and the visual analogue scale (VAS) scores at 24 and 72 hours were lower in the UVATS group compared to the MVATS group, while the chest tube retention time and hospitalization time were shorter than those in the MVATS group (P<0.05). The quality of life at six months after surgery in the UVATS group was significantly higher than that in the MVATS group (P<0.05). Conclusions: UVATS and MVATS have similar outcomes in patients with NSCLC. Although UVATS surgery takes longer and is associated with more interoperative bleeding, it can reduce postoperative pain, shorten postoperative recovery time, and help further improve the quality of life of patients after surgery.

[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.

Postoperative pulmonary complications in awake video-assisted thoracoscopic surgery: Our 10-year experience.

Background: The aim of this study was to evaluate the effect of awake video-assisted thoracoscopic surgery on postoperative pulmonary complications among patients with different risk scores using the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT). Methods: Between January 2011 and August 2021, a total of 246 patients (158 males, 88 females; mean age: 59.1±13.6 years; range, 25 to 84 years) who underwent awake video-assisted thoracoscopic surgery were retrospectively analyzed. According to the ARISCAT scores, the patients with low and intermediate scores were included in Group L (n=173), while those with high scores (n=73) were included in Group H. Sedation protocol consisted of the combination of midazolam and fentanyl with propofol infusion, if necessary. Oxygen was delivered via face mask or nasal canula (2 to 5 L/min) maintaining an oxygen saturation of >95%, and analgesia was achieved with intercostal nerve block. Demographics, operative, and postoperative data of the patients, and pulmonary complications were evaluated. Results: Demographics, operative, and postoperative data were similar between the groups. Postoperative pulmonary complications were observed in 20 (27%) patients in Group H and 29 (17%) patients in Group L without statistically significant difference (p=0.056). Surgical approaches consisted of pleural procedures (n=194) and pulmonary resection (n=52). The incidence of pulmonary complications was significantly higher in the pulmonary resection compared to non-pulmonary procedures (p=0.027). Conclusion: Awake video-assisted thoracoscopic surgery seems to be beneficial in reducing the incidence of postoperative pulmonary complications in high-risk patients as assessed with the ARISCAT.
