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.

Pulmonary cryptococcosis (PC) is a common opportunistic fungal infection caused by Cryptococcus neoformans or Cryptococcus gattii. PC primarily invades the respiratory system, followed by the central nervous system. Few clinical reports have examined the coexistence of PC and lung cancer. This study reports the case of a 54-year-old immunocompetent PC patient with lung adenocarcinoma. Chest CT revealed multiple nodules in the right lung, with the largest nodule located in the dorsal segment of the right lower lobe. 18 F‑FDG positron emission tomography-computed tomography (PET-CT) revealed elevated glucose metabolism in the dorsal segment of the right lower lobe, which suggested lung cancer. The metabolism level of the nodule in the basal segment of the right lower lobe and the anterior segment of the right upper lobe was not abnormally increased, but the possibility of a malignant tumour could not be excluded. The pulmonary nodules in the dorsal segment and the basal segment of the right lower lobe were simultaneously resected via video-assisted thoracic surgery (VATS), and the final histopathology revealed primary lung adenocarcinoma and pulmonary cryptococcal infection, respectively. After surgery, antifungal treatment was administered for 3 months. Over the 3-year follow-up, contrast-enhanced computed tomography (CT) revealed no recurrence of either disease. This case study highlights the possibility of dualism in the diagnosis of multiple pulmonary nodules on chest CT, such as the coexistence of lung cancer and PC. Surgical resection is recommended for micronodules that are not easy to diagnose via needle biopsy; in addition, early diagnosis and treatment are helpful for ensuring a good prognosis. This paper reports the clinical diagnosis and treatment of one patient with pulmonary cryptococcal infection of the right lung complicated with lung adenocarcinoma, including 3 years of follow-up, providing a reference for clinical practice.

Objective To investigate the effect of video-assisted thoracoscopic surgery (VATS) on immune function and inflammatory factors in patients with non-small cell lung cancer (NSCLC). Methods A total of 60 patients with NSCLC admitted to our hospital from July 2020 to June 2022 were selected and divided into the observation group (30 cases) and the control group (30 cases) according to the random number table method. The control group was treated with thoracotomy.and the observation group was treated with VATS. The operation-related indexes, immune function indexes [CD4+,CD8+,CD4/CD8+ ratio, immunoglobulin (IgG, IgA, IgM], inflammatory factors [C-reactive protein (CRP), interleukin-2 receptor(IL-2R), matrix metalloproteinase-9(MMP-9)], incidence of complications and 1-year survival rate were compared between the two groups. Results The intraoperative blood loss and intraoperative blood transfusion in the observation group were lower than those in the control group. and the operation time and hospitalization time were shorter than those in the control group, the differences were statistically significant(P<0.05). There was no significant difference being found in the comparison of the number of N2 lymph nodes and lymph node dissection between the two groups (P>0.05). There was no significant difference being found in the comparison of the immune function indexes between the two groups before treatment (P>0.05). The immune function indexes of the two groups after treatment were lower than those before treatment, and the difference was statistically significant(P<0.05). The CD4/CD8 ratio and the levels of CD4, IgG, IgA and IgM in the observation group were higher than those in the control group, and the CD8 level was lower than that in the control group, the differences were statistically significant (P<0.05). There was no significant difference being found in the comparison of the levels of inflammatory factors between the two groups before treatment(P>0.05). After treatment, the levels of IL-2R, CRP and MMP-9 in the two groups were higher than those before treatment, and the levels of each index in the observation group were lower than those in the control group, the differences were statistically significant (P<0.05). There was no significant difference in the incidence of complications and 1-year survival rate between the two groups (P>0.05). Conclusion VATS can shorten the operation time and hospitalization time of NSCLC patients, reduce the amount of intraoperative blood loss and the level of inflammatory factors, and has little effect on immune function.

Purpose: The detection of small lung nodules in thoracoscopic procedure is difficult when the lesions are not located within the outer border of the lung. In the case of ground-glass opacities, it is often impossible to palpate the lesion. Marking lung nodules using a radiotracer is a known technique. We analysed the accuracy and safety of the technique and the potential benefits of operating in a hybrid operating room. Methods: 57 patients, including 33 (58%) females with a median age of 67 years (range 21-82) were included. In 27 patients, we marked and resected the lesion in a hybrid room. In 30 patients, the lesion was marked at the department of radiology the day before resection. [99mTc]Tc-Macrosalb (Pulmocis®) was used at an activity of 1 MBq in the hybrid room and at an activity of 3 MBq the day before to get technical feasible results. Radioactivity was detected using the Neoprobe® detection system. Results: Precise detection and resection of the nodules was possible in 95% of the lesions and in 93% of the patients. Complete thoracoscopic resection was possible in 90% of the patients. Total conversion rate was 10%, but conversion due to failure of the marking of the nodule was observed in only 5% of the patients. Histology revealed 28 (37%) primary lung cancers, 24 (32%) metastases and 21 (28%) benign lesions. In 13 (23%) patients, minor complications were observed. None of them required additional interventions. Conclusion: The radio-guided detection of small pulmonary nodules is very accurate and safe after CT-guided injection of [99mTc]Tc-Macrosalb. Performing the operation in a hybrid room has several logistic advantages and allows using lower technetium-99m activities. The technique allows minimally invasive lung sparing resection and prevents overtreatment of benign and metastatic lesions. [ABSTRACT FROM AUTHOR]

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.

Introduction: Hyperfunctional ectopic parathyroid glands in the mediastinum pose a challenge to diagnosis and require optimal surgical management. Video-assisted thoracoscopic surgery (VATS) has emerged as a promising minimally invasive approach, offering potential benefits in terms of both patient comfort and oncological principles. This study aimed to evaluate the effectiveness and safety of VATS for the treatment of hyperfunctional ectopic parathyroid glands in the mediastinum. Methods: Among the 538 patients with mediastinal tumors who underwent thoracoscopic surgery at Istanbul University (2008–2021), 11 exhibited hyperfunctional ectopic parathyroid glands. The localization of the glands was performed using various diagnostic techniques, including neck ultrasound, sestamibi scan, CT (computerized tomography), and SPECT (Single-photon emission computed tomography). VATS (Video-assisted thoracoscopic surgery) was used to remove ectopic parathyroid glands in all 11 patients, with no need for conversion to open surgery. Results: The pathological results showed that VATS successfully removed the ectopic glands in all 11 patients. Serum parathyroid hormone (PTH) levels were monitored intraoperatively, and frozen sections were used to confirm the presence of parathyroid adenomas in all cases. Postoperative analysis showed that PTH levels dropped by at least 50% within 10–15 minutes after adenoma removal. Conclusion: VATS is a safe and effective method for the treatment of hyperfunctional ectopic parathyroid glands in the mediastinum with a low risk of complications. [ABSTRACT FROM AUTHOR]

Surgical intervention is advisable for both asymptomatic and symptomatic CCAM children. This study aims to compare and analyze the efficacy of thoracoscopic and Da Vinci robot-assisted procedures in the management of CCAM among pediatric patients. The clinical data of 188 pediatric patients diagnosed with CCAM and admitted to the Children's Hospital, Zhejiang University School of Medicine, from April 2019 to April 2023 were retrospectively analyzed. The Clavien-Dindo classification was employed for the systematic categorization of postoperative complications. The demographic and clinical characteristics of the patients were comparable between the two groups. Postoperative outcomes, such as the chest tube indwelling rate (92.6% vs 36.2%, p < 0.001∗), chest tube duration (2.0 (2.0–3.0) days vs 1.0 (1.0–2.0) days, p < 0.001∗), and length of postoperative hospital stay (6.0 (5.0–7.0) days vs 5.0 (5.0–6.0) days, p < 0.001∗), favored RATS over VATS. Additionally, there was no significant difference in complications between the two group, but the p-value is in a critical state. Ⅲa complications (mainly composed of postoperative thoracentesis procedures) manifesting as a higher rate in the RATS, nearly double that observed in the VATS. Robot-assisted thoracoscopic lung resection is demonstrated to be safe and feasible, with notable advantages in short-term postoperative clinical outcomes. Nevertheless, the practicality and long-term benefits of this technique necessitate further refinement and dedicated study. LEVEL III. [ABSTRACT FROM AUTHOR]

Background: The advent of robot-assisted thoracoscopic surgery (RATS) has completely revolutionized the modality of thymectomy, which could reportedly achieve equivalent efficacy compared with a minimally invasive approach. This study was conducted to further compare the perioperative outcomes between these two modalities. Methods: A retrospective single-center study that included patients receiving either a robotic or video-assisted thoracoscopic (VAT) thymectomy between February 2021 and January 2023 was conducted. All the patients were pathologically confirmed with thymic epithelial tumors. Clinical and pathological characteristics and perioperative outcomes were collected and compared between these two cohorts. Results: A total of 190 patients were included in this study, with 61 (32.1%) and 129 (67.9%) receiving robotic and video-assisted thymectomy, respectively. The clinicopathological characteristics were not significantly different between these 2 groups. The size of the resected specimens in the RATS cohort was larger than the VATS cohort [median (IQR), 13.0 (8.0–16.0) vs. 9.0 (6.7–12.0) cm, p < 0.001], while the procedural duration was longer for the RATS group than its counterpart [median (IQR), 105 (85–143) vs. 85 (69–115) min, p = 0.001]. Moreover, no other significant difference was observed between these two groups. Since more than half of the robotic thymectomy was performed using a subxiphoid approach, a subgroup analysis was further conducted. Similarly, the robotic group through a subxiphoid approach harbored a longer procedural duration, and the size of the specimens obtained was larger than the VATS group [median (IQR), 14.0 (11.0–16.5) vs. 12.5 (8.5–15.0) cm, p = 0.061]. Conclusions: The early clinical efficacy of robotic thymectomy was proven comparable to the established VATS approach, and such a modality might have strength when obtaining larger specimens, which could contribute to improving long-term efficacy. Despite the longer procedural duration recorded in the early stage of conducting robotic thymectomy, further accumulation would help decrease the time. [ABSTRACT FROM AUTHOR]

Objective: Considering the controversial benefits of video-assisted thoracoscopic surgery (VATS), we intended to evaluate the impact of surgical approach on cardiac function after lung resection using myocardial work analysis. Methods: Echocardiographic data of 48 patients (25 thoracotomy vs. 23 VATS) were retrospectively analyzed. All patients underwent transthoracic echocardiography (TTE) within 2 weeks before and after surgery, including two-dimensional speckle tracking and tissue Doppler imaging. Results: No notable changes in left ventricular (LV) function, assessed mainly using the LV global longitudinal strain (GLS), global myocardial work index (GMWI), and global work efficiency (GWE), were observed. Right ventricular (RV) TTE values, including tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TASV), right ventricular global longitudinal strain (RVGLS), and RV free-wall GLS (RVFWGLS), indicated greater RV function impairment in the thoracotomy group than in the VATS group [TAPSE(mm) 17.90 ± 3.80 vs. 21.00 ± 3.48, p = 0.006; d = 0.84; TASV(cm/s): 12.40 ± 2.90 vs. 14.70 ± 2.40, p = 0.004, d = 0.86; RVGLS(%): − 16.00 ± 4.50 vs. − 19.40 ± 2.30, p = 0.012, d = 0.20; RVFWGLS(%): − 11.50 ± 8.50 vs. − 18.31 ± 5.40, p = 0.009, d = 0.59; respectively]. Conclusions: Unlike RV function, LV function remained preserved after lung resection. The thoracotomy group exhibited greater RV function impairment than did the VATS group. Further studies should evaluate the long-term impact of surgical approach on cardiac function. [ABSTRACT FROM AUTHOR]

In this era of endoscopic surgery, feedback from recorded surgical videos is useful and efficient; therefore, effective methods of obtaining this feedback are needed. We analyzed surgical videos using motion analysis software and verified the usefulness of visualizing and objectively evaluating surgical procedures. We measured the grasping and traction angles of the vascular sheath when using forceps and the trajectory of the forceps tip for the upper pulmonary vein during right upper lobectomy during video‐assisted thoracoscopic surgery performed by three trainers and trainees. Compared with the trainers, the trainees exhibited insufficient traction of the vascular sheath, performed many slow and unnecessary manipulations, and sometimes performed sudden and fast movements. By visualizing the surgical procedures, the trainee will be better able to identify dangerous or futile movements. It may also make it easier to objectively recognize improvements in one's technique. Motion analysis software could allow for efficient surgical education and self‐learning. [ABSTRACT FROM AUTHOR]

Objective: To compare the uniportal and multiportal video-assisted thoracoscopic surgery (VATS) in patients with nonsmall- 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.

Background: Atrial fibrillation (AF) has become the most common postoperative arrhythmia of thoracic surgery. This study aimed to investigate the risk factors and complications of perioperative atrial fibrillation (PoAF) in elderly patients who underwent video-assisted thoracoscopic surgery (VATS). Methods: Data were collected from patients who underwent VATS between January 2013 and December 2022 at Peking Union Medical College Hospital (PUMCH). Univariable analyses and multivariable logistic regression analyses were used to determine the factors correlated with PoAF. Receiver operating characteristic (ROC) curve was used to evaluate the discrimination of the indicators to predict PoAF. Results: The study enrolled 2920 patients, with a PoAF incidence of 5.2% (95% CI 4.4%-6.0%). In the logistic regression analyses, male sex (OR=1.496, 95% CI 1.056– 2.129, P=0.024), left atrial anteroposterior dimension (LAD) ≥ 40 mm (OR=2.154, 95% CI 1.235– 3.578, P=0.004), hypertension (HTN) without regular treatment (OR=2.044, 95% CI 0.961– 3.921, P=0.044), a history of hyperthyroidism (OR=4.443, 95% CI 0.947– 15.306, P=0.030), surgery of the left upper lobe (compared to other lung lobes) (OR=1.625, 95% CI 1.139– 2.297, P=0.007), postoperative high blood glucose (BG) (OR=2.482, 95% CI 0.912– 5.688, P=0.048), and the time of chest tube removal (per day postoperatively) (OR=1.116, 95% CI 1.038– 1.195, P=0.002) were found to be significantly associated with PoAF. The area under the ROC curve was 0.707 (95% CI 0.519– 0.799). 86.9% patients were successfully converted to sinus rhythm. Compared with the non-PoAF group, the PoAF group had significantly greater risks of prolonged air leakage, postoperative acute coronary syndrome, longer ICU stays, and longer hospital stays. Conclusion: Male sex, LAD≥ 40 mm, HTN without regular treatment, a history of hyperthyroidism, surgery of the left upper lobe, postoperative BG, and the time of chest tube removal were associated with PoAF. These findings may help clinicians identify high-risk patients and take preventive measures to minimize the incidence and adverse prognosis of PoAF. [ABSTRACT FROM AUTHOR]

Post-coronary artery bypass graft (CABG) surgery, chylothorax is a rare, but a serious, complication. We report a case of 49-year-old female who underwent CABG, and developed pleural effusion on post-operative day 2 which was milky in nature. Chylothorax was confirmed based on the biochemical analysis of the pleural fluid. As the medical line of management failed, video-assisted thoracoscopic surgery (VATS) was done and thoracic duct clipped on the right side. Close to the proximal portion of the left internal thoracic artery, disrupted tributaries of thoracic duct were noted and clipped. Rarity of the case and management is highlighted.

Background: Patients with early-stage lung tumors that are highly suspicious for malignancy typically undergo a preoperative diagnostic workup, primarily through bronchoscopy or transthoracic biopsy. Those without a preoperative diagnosis may alternatively be treated with upfront surgery, contingent upon the potential for intraoperative diagnosis. Previous studies have yielded conflicting results regarding the impact of upfront surgery on the survival of these patients. Our study aimed to elucidate the effect of upfront surgery on the survival outcomes of patients undergoing surgery for early-stage lung cancer without a preoperative diagnosis. Methods: We analyzed the survival rate of 158 consecutive patients who underwent pulmonary resection for stage I lung cancer, either with or without a preoperative diagnosis. Results: A total of 86 patients (54%) underwent upfront surgery. This approach positively impacted both disease-free survival (p=0.031) and overall survival (p=0.017). However, no significant differences were observed across subgroups based on sex, smoking status, forced expiratory volume in 1 second, histologic tumor size, or histologic subtype. Univariate analysis identified upfront surgery (p=0.020), age (p=0.002), maximum standardized uptake value (SUVmax) exceeding 7 (p=0.001), and histological tumor size greater than 20 mm (p=0.009) as independent predictors. However, multivariate analysis indicated that only SUVmax greater than 7 (p=0.011) was a significant predictor of unfavorable survival. Conclusion: Upfront surgery does not appear to confer a survival advantage in patients with stage I lung cancer undergoing surgical intervention.

Mediastinal parathyroid cysts (MPCs) are extremely rare, benign lesions arising from the parathyroid glands and residing within the thoracic cavity. This study aims to advance understanding of MPC, emphasizing accurate diagnosis and management approaches for this rare condition. A 46-year-old woman presented with dysphagia for one week. Blood tests revealed elevated parathyroid hormone (PTH) (112.8 pg/mL) and normal serum calcium (9.54 mg/dL). Ultrasonography identified a large, well-defined cystic nodule measuring 46 × 30 × 25 mm, extending retro-sternally in the right upper third of the chest. A subsequent high-resolution computed tomography scan of the chest revealed a large space-occupying lesion (47 × 43 × 31 mm) in the superior mediastinum, near the esophagus, suggesting an esophageal duplication cyst or, less likely, a bronchogenic cyst. Video-assisted thoracoscopic surgery (VATS) was performed, and the entire cyst was excised, confirmed histologically as a mediastinal parathyroid cyst. Mediastinal involvement of PCs poses diagnostic challenges due to their rarity and diverse clinical presentations. Surgical excision is necessary for symptomatic cases, with VATS emerging as a favorable approach.

Abstract Pulmonary cryptococcosis (PC) is a common opportunistic fungal infection caused by Cryptococcus neoformans or Cryptococcus gattii. PC primarily invades the respiratory system, followed by the central nervous system. Few clinical reports have examined the coexistence of PC and lung cancer. This study reports the case of a 54-year-old immunocompetent PC patient with lung adenocarcinoma. Chest CT revealed multiple nodules in the right lung, with the largest nodule located in the dorsal segment of the right lower lobe. 18 F‑FDG positron emission tomography-computed tomography (PET-CT) revealed elevated glucose metabolism in the dorsal segment of the right lower lobe, which suggested lung cancer. The metabolism level of the nodule in the basal segment of the right lower lobe and the anterior segment of the right upper lobe was not abnormally increased, but the possibility of a malignant tumour could not be excluded. The pulmonary nodules in the dorsal segment and the basal segment of the right lower lobe were simultaneously resected via video-assisted thoracic surgery (VATS), and the final histopathology revealed primary lung adenocarcinoma and pulmonary cryptococcal infection, respectively. After surgery, antifungal treatment was administered for 3 months. Over the 3-year follow-up, contrast-enhanced computed tomography (CT) revealed no recurrence of either disease. This case study highlights the possibility of dualism in the diagnosis of multiple pulmonary nodules on chest CT, such as the coexistence of lung cancer and PC. Surgical resection is recommended for micronodules that are not easy to diagnose via needle biopsy; in addition, early diagnosis and treatment are helpful for ensuring a good prognosis. This paper reports the clinical diagnosis and treatment of one patient with pulmonary cryptococcal infection of the right lung complicated with lung adenocarcinoma, including 3 years of follow-up, providing a reference for clinical practice.

Background: One-lung ventilation is used to improve surgical visualization and facilitate thoracoscopic manipulations; however, it induces ventilation/perfusion mismatch, exacerbating the inflammatory response that causes hypoxemia in the perioperative period. Opioid analgesics are the main analgesic drugs used during video-assisted thoracoscopic surgery (VATS), but their use is associated with adverse effects and higher risk of respiratory complications. Corrective measures to eliminate hypoxemia, reduce the inflammatory response, control pain, and minimize opioid-induced adverse effects are crucial in thoracic surgery.Objective: To study the efficacy of dexmedetomidine in reducing lung damage and postoperative complications after VATS.Materials and methods: We examined 100 patients who underwent lobectomy via a thoracoscopic approach. The patients were grouped based on anesthetic management: group 1 (n = 50) with intraoperative dexmedetomidine and group 2 (n = 50) without it. We determined the level of pro-inflammatory cytokines IL-6, IL-8, and TNF and calculated PaO2/FiO2 and A-aDO2. We also assessed the postoperative pain intensity, need for trimeperidin promedol and tramadol, and incidence of postoperative complications.Results: During one-lung ventilation, patients from group 1 had higher PaO2/FiO2 values (P = .025). The A-aDO2 value was higher in group 2 (P = .006). After surgery, we found differences in the content of TNF and IL-8 (P < .001). Twenty-four hours after surgery, we recorded a more significant prevalence of the studied cytokines in group 2 (P < .001). There were no significant differences in the pain dynamics on the first postoperative day (P > .05). Opioid analgesics were less needed in group 1 than in group 2 (P < .001). The incidence of postoperative complications did not differ significantly.Conclusions: Dexmedetomidine in thoracic surgery improves the oxygenation and reduces the percentage of intrapulmonary shunting by inhibiting the release of pro-inflammatory cytokines. In the postoperative period, dexmedetomidine reduces the need for opioid analgesics, but does not affect the pain level or incidence of complications.

Abstract Background Spontaneous hemopneumothorax is a rare condition that can be life-threatening if not promptly diagnosed and treated. We report a case of early treatment with transcatheter arterial embolization and video-assisted thoracoscopic surgery. Case presentation A 19-year-old Japanese male was diagnosed with left pneumothorax and underwent chest tube drainage. A total of 10 hours after admission, the patient developed dyspnea, chest pain, and sudden massive bloody effusion. Contrast-enhanced computed tomography revealed contrast extravasation near the left lung apex, and spontaneous hemopneumothorax was diagnosed. Angiography revealed bleeding from a branch of the subscapular artery and transcatheter arterial embolization was performed. The patient underwent video-assisted thoracoscopic surgery and recovered uneventfully. Conclusions Anesthesiologists involved in urgent surgeries must be aware that a patient with spontaneous pneumothorax can develop a hemopneumothorax, even when full lung expansion has been obtained following chest tube drainage, owing to latent aberrant artery disruption. Interprofessional team engagement is essential for spontaneous hemopneumothorax management.

Background: Video-assisted thoracoscopic surgery (VATS) is recognized as a safe and effective treatment modality for early-stage lung cancer and anterior mediastinal masses. Recently, novel articulating instruments have been developed and introduced to endoscopic surgery. Here, we share our early experiences with VATS major pulmonary resection and thymectomy performed using ArtiSential articulating instruments. Methods: At the Seoul Metropolitan Government-Seoul National University Boramae Medical Center, 500 patients underwent VATS pulmonary resection between July 2020 and April 2023, while 43 patients underwent VATS thymectomy between January 2020 and April 2023. After exclusion, 224 patients were enrolled for VATS major pulmonary resection, and 38 were enrolled for VATS thymectomy. ArtiSential forceps were utilized in 35 of the 224 patients undergoing pulmonary resection and in 12 of the 38 individuals undergoing thymectomy. Early clinical outcomes were retrospectively analyzed. Results: No significant differences were observed in sex, age, surgical approach, operation time, histological diagnosis, or additional procedures between the patients who underwent surgery using novel articulating instruments and the group treated with conventional endoscopic instruments for both VATS major pulmonary resection and thymectomy. However, the use of the novel articulating endoscopic forceps was associated with a significantly larger number of dissected lymph nodes (p=0.028) and lower estimated blood loss (p=0.009) in VATS major pulmonary resection. Conclusion: Major pulmonary resection and thymectomy via VATS using ArtiSential forceps were found to be safe and effective, with early clinical outcomes comparable to established methods. Further research into long-term clinical outcomes and cost-effectiveness is warranted.

BACKGROUND: Minimally invasive surgeries for non-small cell lung cancers (NSCLCs) such as video-assisted thoracoscopic surgeries (VATSs) and robotic-assisted thoracoscopic surgeries (RATSs) have become standard of care for patients needing surgical resection in early stages. The role for neoadjuvant systemic therapy has increased with patients receiving neoadjuvant systemic chemotherapy and immunotherapy. However, there has been some equipoise over the intraoperative and overall outcomes for these patients. Here, we review the current data regarding outcomes of patients undergoing minimally invasive thoracic surgical resection after systemic chemotherapy, immunotherapy, or both. METHODS: A systematic literature review of randomized controlled trials and observational studies presenting data on patients with NSCLC that underwent neoadjuvant systemic therapy followed by minimally invasive surgery was performed assessing complications, conversion rates, and lymph node yield. RESULTS: Our search strategy and review of references resulted in 239 publications to screen with 88 full texts assessed and 21 studies included in our final review. VATS had a statistically significant higher lymph node yield in five studies. The reported conversion rates ranged from 0 to 54%. Dense adhesions, bleeding, and difficult anatomy were the most common reported reasons for conversion to open surgeries. The most common complications between both groups were prolonged air leak, arrythmia, and pneumonia. VATS was found to have significantly fewer complications in three papers. CONCLUSIONS: The current literature supports VATS as safe and feasible for patients with NSCLC after neoadjuvant systemic treatment. Surgeons should remain prepared to convert to open surgeries in those patients with dense adhesions and bleeding risk.

Background Video-assisted thoracoscopic surgery is a commonly used procedure for treating congenital pulmonary airway malformation (CPAM) in infants, particularly when performing segmentectomy for segmental lesions. An innovative technique employing near-infrared fluorescence (NIRF) imaging with intravenous indocyanine green (ICG) has been utilized to delineate the intersegmental demarcation during surgery. However, no previous reports have investigated this method's application, specifically in infants. The primary aim of this study was to assess the safety and efficacy of the NIRF imaging with ICG approach in this context. Methods Between January 2021 and April 2022, a total of 19 consecutive segmentectomies were conducted using the NIRF imaging with ICG method to precisely identify the intersegmental plane. The results were concurrently compared with those obtained using the modified inflation–deflation technique. Comprehensive imaging and clinical data were gathered and analyzed to assess the safety and accuracy of the NIRF imaging with ICG approach. Results The study involved infants with a median age of 5.12 months (mean body weight of 8.08 g). All segmentectomies were performed successfully without any ICG-related complications. The mean operating time for the surgeries was 88.47 ± 7.94 minutes. Notably, no intraoperative conversions or significant complications were observed in any of the patients. The average hospital stay after surgery was 4.0 ± 0.82 days. During the follow-up period, extending beyond 1-year of postoperation, all patients exhibited excellent recovery with no cases of recurrence. Conclusions Based on our experience, the NIRF imaging with intravenous ICG method proved to be both safe and effective when performing segmentectomy for infants with CPAM. Low doses of ICG did not hinder the accurate identification of the intersegmental plane. [ABSTRACT FROM AUTHOR]

Abstract Background Multiportal video-assisted thoracic surgery (mVATS) is the standard approach for the surgical treatment of spontaneous pneumothorax. However, uniportal VATS (uVATS) has emerged as an alternative aiming to minimize surgical morbidity. This study aims to strengthen the evidence on the safety and efficiency of uVATS compared to mVATS. Methods From January 2004 to December 2020, records of patients who had undergone surgical treatment for primary or secondary spontaneous pneumothorax were evaluated for eligibility. Patients who had undergone pleurectomy combined with bullectomy or apical wedge resection via uVATS or mVATS were included. Surgical characteristics and postoperative data were compared between patients who had undergone surgery via uVATS or mVATS. Univariable and multivariable analyses were performed to determine whether the surgical approach was associated with any complication (primary outcome), major complications (i.e., Clavien-Dindo ≥ 3), recurrence, prolonged hospitalization or prolonged chest drainage duration (secondary outcomes). Results A total of 212 patients were enrolled. Patients treated via uVATS (n = 71) and mVATS (n = 141) were significantly different in pneumothorax type (secondary spontaneous; uVATS: 54 [76%], mVATS: 79 [56%]; p = 0.004). No significant differences were observed in (major) complications and recurrence rates between both groups. Multivariable analyses revealed that the surgical approach was no significant predictor for the primary or secondary outcomes. Conclusions This study indicates that uVATS is non-inferior to mVATS in the surgical treatment of spontaneous pneumothorax regarding safety and efficiency, and thus the uVATS approach has the potential for further improvements in the perioperative surgical care for spontaneous pneumothorax.

Abstract Background Pneumothorax is a non-physiological collection of air in the pleural space. Pneumothoraces can be broadly divided into Primary, Secondary, and Traumatic. Cancer of the lung is a known cause of secondary pneumothorax in both primary and metastatic lesions, however, pneumothorax as the presentation of lung cancer is exceedingly rare. Non-small cell lung carcinoma (NSCLC) has been reported in the literature to present with a pneumothorax, particularly in adeno/squamous cell carcinomas. It is almost completely unheard of for small cell lung carcinoma (SCLC) to present with a pneumothorax. Case Presentation We present the case of a 62-year-old male patient, presenting twice in two months with spontaneous pneumothorax. The initial management involved admission and chest drain insertion. The patient has a past medical history of COPD and a significant smoking history. On the second admission, he underwent a video-assisted thoracoscopic (VATS) bullectomy and talc pleurodesis. The pathology report of the resected specimen confirmed SCLC with extensive infiltration. No gross evidence of metastatic spread was present on CT. Due to the R1 resection and significant risk of recurrence, the management plan included four cycles of adjuvant chemotherapy with carboplatin and etoposide, and radiotherapy as a consideration upon completion. Conclusions Pneumothorax as the presentation of lung cancer imparts a very poor prognosis, however the reasons for this are largely unknown. Furthermore, the mechanisms underlying spontaneous pneumothorax in lung cancer are also not well understood.

Abstract Background The erector spinae plane block (ESPB) is a new analgesic method used in thoracic surgery. However, few studies have characterized their effects on perioperative opioid consumption. We aimed to evaluate the effects of ESPB on perioperative opioid consumption in patients who underwent video-assisted thoracoscopic surgery (VATS). Methods This was a randomized, observer-blinded clinical trial at a single-centre academic hospital. Eighty patients were scheduled for thoracoscopic segmentectomy or lobectomy by VATS for lung cancer. Forty participants were randomly assigned to ESPB or control group. All patients received intravenous patient-controlled postoperative analgesia. Perioperative opioid consumption, visual analogue scale (VAS) scores, and adverse events were recorded. Results Intraoperative and postoperative opioid consumption and static/dynamic VAS scores were significantly lower in the early hours after VATS in the ESPB group (p

Abstract Background Nexplanon implants are a common hormonal contraceptive modality. Though rare, these devices can embolize into the injured wall of the basilic vein, through the right heart, and finally wedge itself into a pulmonary artery. With adherence to the arterial wall over time, it becomes less amenable to endovascular retrieval. Patients may present with symptoms mimicking a pulmonary embolism, or without any symptoms at all. In asymptomatic cases, endovascular retrieval and/or surgery is required when patients wish to begin having children prior to biological inactivity. The current literature showed as little as nine case reports detailing lung tissue removal in the aim of reversing a patient’s implanted contraceptive device. Case presentation A 22-year-old asymptomatic active-duty Caucasian female presented for elective outpatient Nexplanon removal. The suspicion of possible implant migration arose when it was discovered to be non-palpable in her left arm. After plain film x-rays failed to localize the implant, a chest x-ray and follow-up Computed Tomography (CT) scan revealed that the Nexplanon had migrated to a distal branch of the left pulmonary artery. Due to the patient’s strong desires to begin having children, the decision was made for removal. Initial endovascular retrieval failed due to Nexplanon encapsulation within the arterial wall. Ultimately, the patient underwent a left video-assisted thoracoscopic surgery (VATS) for exploration and left lower lobe basilar S7–9 segmentectomy, which successfully removed the Nexplanon. Conclusions Implanted contraceptive devices can rarely result in migration to the pulmonary vasculature. These radiopaque devices are detectable on imaging studies if patients and clinicians are unable to palpate them. An endovascular approach should be considered first to spare lung tissue and avoid chest-wall incisions, but can be complicated by encapsulation and adherence to adjacent tissue. A VATS procedure with single-lung ventilation via a double-lumen endotracheal tube allows surgeons to safely operate on an immobilized lung while anesthesiologists facilitate single-lung ventilation. This patient’s case details the uncommon phenomenon of Nexplanon migration, and the exceedingly rare treatment resolution of lung resection to remove an embolized device.

Abstract 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.

Abstract Objective Chest drainage is a standard procedure in thoracoscopic surgery for lung cancer. However, chest tube placement may deteriorate the ventilation capacity and increase difficulty of postoperative management of patients. The study investigated on the effects of enhanced recovery after surgery (ERAS) program focusing on chest tube management on surgical recovery of lung cancer patients. Methods The study population consisted of 60 patients undergoing video-assisted thoracoscopic surgery (VATS) after implementation of ERAS program and another group of 60 patients undergoing VATS before implementation of ERAS program. Results The mean time of first food intake was 12.9 h required for the ERAS group, which was significantly shorter than 18.4 h required for the control group (p

Objectives: To identify factors associated with prolonged postoperative length of stay (LOS) after VATS lobectomy (VATS-L), explore potential intersurgeon variation in LOS and ascertain whether or not early discharge influences hospital readmission rates. Methods: We conducted a retrospective analysis of patients who underwent VATS-L at a single academic center between 2018 and 2021. Each VATS lobectomy procedure was performed by 1 of 7 experienced thoracic surgeons. The primary end point of interest was prolonged LOS, defined as an index LOS >3 days. Results: Among 1006 patients who underwent VATS lobectomy, 632 (63%) had a prolonged LOS. On multivariate analysis, the factors independently associated with prolonged LOS were: surgeon (P 3, and prior ipsilateral thoracic surgery or sternotomy. There was no association between LOS ≤3 days and hospital readmission (20 [5.3%] vs 39 [5.9%]; OR, 0.88; 95% CI, 0.50-1.53). Conclusions: An intersurgeon variation in postoperative LOS after VATS-L exists and is independent of patient baseline characteristics or perioperative complications. This variation seems to be more closely related to differences in postoperative management and discharge practices rather than to surgical quality. Postoperative discharge within 3 days is safe and does not increase hospital readmissions.

Abstract 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

Abstract Background Hyperparathyroidism (HPT) is a disease caused by hypersecretion of one or more parathyroid glands, it can be associated with ectopic mediastinal parathyroid glands (MEPA) in 2% of cases. The use of video-assisted thoracoscopic surgery (VATS) for the surgical resection of these glands is a safe, cost-effective, and low morbidity option for patients with MEPA. We report a case series of patients with this disease managed with VATS, the first in Mexico and Latinamerica. Methods From 2008 to 2022, a retrospective study involving patients with MEPA and treated by VATS approach was performed in a tertiary hospital in Mexico city. Relevant biochemical and clinical variables such as imaging studies, pre and postoperative laboratory results, surgical strategy, outcomes and pathological analysis were analyzed. Results Four cases of mediastinal parathyroid adenomas causing HPT were included. All patients were female with a median age of 52.5 years-old (range 46–59 years), half of the patients had primary HPT and the others tertiary HPT after kidney transplant. 75% of cases had a MEPA in the medium mediastinum, all had a preoperative positive SPECT-CT 99mTc Sestamibi scan. Mean preoperative PTH was 621.3pg/mL (182-1382pg/mL). All patients successfully underwent parathyroidectomy with a VATS approach, no deaths were reported. Conclusions VATS is a minimally invasive surgery that provides adequate access to mediastinal located glands, optimal visualization of mediastinal structures and has a high resection success rate with less complications and morbidity than open approaches.

No significant differences were observed in adverse effects between the two groups. Conclusions: ESPB reduced intraoperative opioid consumption and early postoperative pain in patients undergoing VATS. Our findings support the view that ESPB is a safe and highly effective option for regional analgesia for VATS. Trial registration: http://www.chictr.org.cn, ChiCTR1800019335. [ABSTRACT FROM AUTHOR]

Objectives: This study evaluates the analgesic effects of intrathecal morphine (ITM) and ultrasound-guided erector spinae plane block (ESPB) in managing postoperative pain following video-assisted thoracoscopic surgery (VATS). Methods: This retrospective observational study examined hospital records and anesthesia documents of 40 patients who underwent VATS at a university hospital between January 2021 and January 2022. The patients were divided into two groups: ITM and ESPB. The comparative analysis included cumulative morphine consumption within the initial 12/24 h after VATS, Numeric Rating Scale (NRS) resting/activity scores, rescue analgesic requirements, and the side effect profile. Results: During the first 12 h postoperatively, the ITM group exhibited lower median morphine consumption than the ESPB group (ITM: 1.9 mg [0.85–3] vs. ESPB: 3.65 mg [3–4.23], p=0.003). Further, within the initial 24 h postoperatively, the ITM group also exhibited lower median morphine consumption compared to ESPB (ITM: 4 mg [1.54–5.38] vs. ESPB: 10 mg [10–10], p<0.001). The NRS resting/activity scores were consistently lower in the ITM group than in the ESPB group at all measurement times (p<0.001). The number of patients receiving rescue analgesic medication was lower in the ITM group than in the ESPB group (ITM, n=6 [30%] vs. ESPB, n=20 [100%]; p<0.001). The side effect profiles of both groups were comparable. Conclusion: ITM reduced morphine consumption, pain scores, and the requirement for rescue analgesia compared with ESPB, with a comparable side effect profile after VATS. [ABSTRACT FROM AUTHOR]

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.

Simple Summary: Lung cancer is the leading cause of death and the second most prevalent cancer worldwide. Recent improvements in radiological technologies enable the early detection of lung cancer. A minimally invasive approach has become a standard therapy for early-stage lung cancer, and therefore, the need for preoperative and intraoperative simulations has increased. Software evolution has broadened the possibilities of three-dimensional (3D) reformatting of computed tomography (CT), resulting in the wide use of 3D CT images in thoracic surgery. However, several issues need to be resolved for future improvement in current 3D CT imaging, such as the necessity of contrast-enhanced CT, the limitation of describing small branches of pulmonary vessels, and the static images not coping with surgical or deflated deformation. This narrative review summarizes the current situation and concerns of 3D CT imaging and its history and explores novel strategies to solve these issues. Radiologic reconstruction technology allows the wide use of three-dimensional (3D) computed tomography (CT) images in thoracic surgery. A minimally invasive surgery has become one of the standard therapies in thoracic surgery, and therefore, the need for preoperative and intraoperative simulations has increased. Three-dimensional CT images have been extensively used, and various types of software have been developed to reconstruct 3D-CT images for surgical simulation worldwide. Several software types have been commercialized and widely used by not only radiologists and technicians, but also thoracic surgeons. Three-dimensional CT images are helpful surgical guides; however, in almost all cases, they provide only static images, different from the intraoperative views. Lungs are soft and variable organs that can easily change shape by intraoperative inflation/deflation and surgical procedures. To address this issue, we have developed a novel software called the Resection Process Map (RPM), which creates variable virtual 3D images. Herein, we introduce the RPM and its development by tracking the history of 3D CT imaging in thoracic surgery. The RPM could help develop a real-time and accurate surgical navigation system for thoracic surgery. [ABSTRACT FROM AUTHOR]

Purpose: Uniportal video-assisted thoracoscopic surgery (VATS) is recognized for its minimally invasive nature, widely adopted globally. However, the evident scarring it leaves often triggers psychological apprehension and resistance to surgery. Transareolar incision, known for its superior cosmetic outcome with no visible scars, poses challenges in women due to the risk of mammary gland damage. In this report, we present successful pulmonary ground glass nodule (GGN) resection using transareolar VATS in female patients, aiming to address these concerns. Materials and Methods: We retrospectively analyzed the clinical data of 35 female patients who underwent GGN resection through transareolar VATS between August 2020 and March 2022. Results: There were no serious complications or perioperative deaths in this cohort of 35 female patients undergoing GGN resection through transareolar VATS. The operations, including local resection or segmentectomy, had an average duration of 70.1 ± 26.4 minutes, with a tube duration of 4.7 ± 2.1 days and a hospitalization time of 7.2 ± 2.3 days. The surgical approach varied, with 21 cases using transareolar uniport, 8 cases assisted by a 3-mm tiny port, and 6 cases converted to two-port VATS. Scar outcomes varied, with 21 cases showing no scar, 8 cases displaying a microscar, and 6 cases presenting a dominant scar of 1.7 ± 0.5 cm. Postoperative pain scores at 1 week and 1 month were 1.9 ± 0.9 and 1.0 ± 0.9, respectively, and the wound numbness occurred in 2.86% (1/35) of cases. Regarding breast complications, 2 patients suffered delayed healing of the incision. No damage and inflammation of glands were detected by breast B-mode ultrasonography. Conclusions: The transareolar incision emerges as a novel approach for VATS in female patients, offering advantages in terms of pain management and cosmetic outcomes. [ABSTRACT FROM AUTHOR]

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).

Background: Lung segmentectomy has gained much more attention as an important surgical method for treating early-stage lung cancer. However, incomplete fissures increase the difficulty of lung segmentectomy. The aim of this study was to analyze the safety and efficacy of the fissure-first approach in precision resection of lung segments for patients with incomplete fissures. Methods: The clinical data of patients with incomplete fissures who underwent lung segmentectomy were retrospectively analyzed. Date was divided into fissure-first approach in lung segmentectomy group (group A) and fissure-last approach in lung segmentectomy group (group B). The general linear data, operation times, intraoperative adverse events, postoperative recovery dates and complications were compared. Results: A total of 122 patients with complete clinical data were included. Patients in group B had more COPD (p < 0.05), and the lesions in group A were more closely related to the hilum of the lung (p < 0.05). Compared to Group B, Group A achieved better surgical outcomes, such as operation time, postoperative hospital stays, intraoperative bleeding, number of intrapulmonary lymph nodes sampled, counts of resected subsegments (except the upper lobe of the right lung), and rate of conversion to thoracotomy (all p < 0.05). Conclusion: The fissure-first approach is a safe and effective surgical approach in lung segmentectomy for patients with incomplete fissures. This approach can reduce the counts of resected subsegments and improve techniques in lung segmentectomy for patients with lung incomplete fissures. [ABSTRACT FROM AUTHOR]

The treatment of symptomatic pseudarthrosis via posterior-only approaches in the setting of neurofibromatosis 1 (NF1) is challenging due to dural ectasias, resulting in erosion of the posterior elements. The purpose of this report is to illustrate a minimally invasive method for performing anterior thoracic fusion for pseudarthrosis in a patient with NF1-associated scoliosis and dysplastic posterior elements. To the best of our knowledge, this is the first documented case of using video-assisted thoracoscopic lateral interbody fusion to treat pseudarthrosis for NF1-associated spinal deformity. The patient underwent video-assisted thoracoscopic anterior spinal fusion via a direct lateral interbody approach with interbody cage placement at T10-T11 and T11-T12, followed by revision of his posterior spinal fusion and instrumentation. The patient had an uneventful postoperative course. At 6 months of follow-up, the patient had complete resolution of his preoperative symptoms and had returned to full-time work with no complaints. At 3 years postoperatively, the patient reported being satisfied with the operation and had continued to work full-time without restrictions. To the best of our knowledge, this is the first report of pseudarthrosis in the setting of NF1-associated scoliosis treated via minimally invasive anterior thoracic fusion facilitated by video-assisted thoracoscopic surgery. This is a powerful technique that allows for safe access for anterior thoracic fusion in the setting of dysplastic posterior anatomy and poor posterior bone stock. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.

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.

Objective: Chest drainage is a standard procedure in thoracoscopic surgery for lung cancer. However, chest tube placement may deteriorate the ventilation capacity and increase difficulty of postoperative management of patients. The study investigated on the effects of enhanced recovery after surgery (ERAS) program focusing on chest tube management on surgical recovery of lung cancer patients. Methods: The study population consisted of 60 patients undergoing video-assisted thoracoscopic surgery (VATS) after implementation of ERAS program and another group of 60 patients undergoing VATS before implementation of ERAS program. Results: The mean time of first food intake was 12.9 h required for the ERAS group, which was significantly shorter than 18.4 h required for the control group (p < 0.0001). The mean time of out-of-bed activity was 14.2 h taken for the ERAS group, which was notably shorter than 22.8 h taken for the control group (p < 0.0001). The duration of chest tube placement was 68.6 h in the ERAS group, which was remarkably shorter than 92.8 h in the control group (p < 0.0001). The rate overall postoperative complications were notably lower in the ERAS group than in the control group (p = 0.018). The visual analogue score (VAS) scores on the second postoperative day exhibited significant differences between the ERAS group and the control group (p = 0.017). The patients in the ERAS group had a shorter hospitalization stay than those in the control group (p < 0.0001). Conclusion: The study suggests the ERAS program focusing on chest tube management could improve surgical recovery, remove patient chest tube earlier, and relieve patient pain after VATS.

Background: Hyperparathyroidism (HPT) is a disease caused by hypersecretion of one or more parathyroid glands, it can be associated with ectopic mediastinal parathyroid glands (MEPA) in 2% of cases. The use of video-assisted thoracoscopic surgery (VATS) for the surgical resection of these glands is a safe, cost-effective, and low morbidity option for patients with MEPA. We report a case series of patients with this disease managed with VATS, the first in Mexico and Latinamerica. Methods: From 2008 to 2022, a retrospective study involving patients with MEPA and treated by VATS approach was performed in a tertiary hospital in Mexico city. Relevant biochemical and clinical variables such as imaging studies, pre and postoperative laboratory results, surgical strategy, outcomes and pathological analysis were analyzed. Results: Four cases of mediastinal parathyroid adenomas causing HPT were included. All patients were female with a median age of 52.5 years-old (range 46–59 years), half of the patients had primary HPT and the others tertiary HPT after kidney transplant. 75% of cases had a MEPA in the medium mediastinum, all had a preoperative positive SPECT-CT 99mTc Sestamibi scan. Mean preoperative PTH was 621.3pg/mL (182-1382pg/mL). All patients successfully underwent parathyroidectomy with a VATS approach, no deaths were reported. Conclusions: VATS is a minimally invasive surgery that provides adequate access to mediastinal located glands, optimal visualization of mediastinal structures and has a high resection success rate with less complications and morbidity than open approaches.
