Background: The purpose of this study is to compare the clinical characteristics and surgical outcomes of thoracotomy and video-assisted thoracoscopic surgery (VATS) in children with congenital lung malformations (CLMs) in a tertiary referring center and to report our modified biportal VATS setting. Methods: This is a single-center retrospective chart review study including children who underwent surgical resection for CLMs between January 2007 and December 2020. Patient characteristics and surgical outcomes were compared between open and thoracoscopy, as well as conventional VATS and biportal VATS. Biportal setting included an anterior utility wound and a camera trocar wound with one-lung ventilation. Results: A total of 100 patients were identified. Twenty patients received thoracotomy, and 80 patients received VATS (67 conventional and 13 biportal VATS). The median age at operation was 0.4 months in the thoracotomy group and 4.7 months in the VATS group. More patients in the thoracotomy group had preoperative symptoms, comorbidities, and emergent operations. The patients who underwent thoracotomy had significantly longer postoperative ICU stays, chest tube durations, hospital stays, and more complications. The pathological analysis revealed 67 congenital pulmonary airway malformations, 27 pulmonary sequestration, 6 hybrid lesions, and one accompanying pleuropulmonary blastoma. Compared to conventional VATS, the ICU stay was shorter in the biportal VATS group, with comparable operative durations, hospital stay and complications. Conclusion: VATS for CLMs is associated with better postoperative recovery and fewer complications. Biportal VATS is also a safe and feasible approach.

Background: The surgical outcome for primary pulmonary cryptococcosis remains unclear. In this study, we investigated the clinical characteristics, treatment, and outcomes of video-assisted thoracoscopic surgery (VATS) for primary pulmonary cryptococcosis. Methods: We retrospectively reviewed the medical records of 49 patients with confirmed pulmonary cryptococcosis who underwent VATS for pulmonary nodules at the National Taiwan University Hospital between May 2013 and March 2019. Serum cryptococcal antigen (CryAg)-positive and CryAg-negative patients were compared. Results: The diagnosis of pulmonary cryptococcosis was confirmed using histopathology or tissue swab culture. The mean age of the patients was 56.0 ± 12.2 years, and 27 patients (55.1%) were male. Most patients were asymptomatic (67.3%) and admitted following the detection of pulmonary lesions on a computed tomography scan of the chest. A greater proportion of patients in the CryAg-positive group (62.5%) underwent lobectomy compared with those in the CryAg-negative group (7.3%, P

Lymphomatoid granulomatosis (LYG) is an Epstein-Barr virus (EBV)-associated lymphoproliferative disease. It is considered a rare entity in pediatric patients. An adolescent male with lobar consolidation suspected of having pneumonia was resistant to antibiotics and had persistently abnormal radiographs with chest pain. The patient was diagnosed with pulmonary LYG through video-assisted thoracoscopic surgery (VATS) lung biopsy. He received eight cycles of rituximab, vincristine, cyclophosphamide, and prednisolone (R-CVP) but had progressive disease. As the patient developed hypogammaglobulinemia after eight courses of rituximab, he received intravenous gamma globulin (IVIG) at regular interval. With immune augmentation effect of IVIG and immune modulation treatment with prednisolone, the patient has shown no aggravation of the lung lesions. Considering its rarity, high mortality, and frequent relapses, diagnostic methods investigating the radiologic abnormalities can help in early treatment initiation.

Abstract Background Resection of lung cancer with chest wall involvement is an invasive procedure. Case presentation We report a case of pulmonary adenocarcinoma with chest wall involvement that was resected through video-assisted thoracoscopic segmentectomy and combined en bloc resection of the chest wall (2nd to 4th ribs). Surgical stress was decreased by reducing the extent of lung parenchymal resection and applying a video-assisted technique with an additional posterior paravertebral incision. Conclusion A thoracoscopic surgical approach involving incisions in areas requiring resection of the proximal, lateral, and posterior sides of the involved ribs can be applied to tumors invading the chest wall.

However, their association with postoperative pain after video-assisted thoracoscopic surgery has not been explored. The aim of this study was to examine the association between vitamin D levels and postoperative pain after video-assisted thoracoscopic surgery.Patients and Methods: This study enrolled 194 adult patients who underwent elective non-cardiac thoracic surgery in Shanghai Pulmonary Hospital from February 2021 to June 2021. Following application of the exclusion criteria, 135 patients who underwent video-assisted thoracoscopic surgery were included in the final analysis. The primary outcome was the incidence of acute postoperative moderate-severe pain. Secondary outcomes included C-reactive protein (CRP), interleukin (IL)-1, IL-6, and tumor necrosis factor-α levels in the immediate postoperative (48 hours) period, as well as pain scores at 3 months after surgery. A multivariable logistic regression model was used to analyze the association between vitamin D levels and acute postoperative moderate-severe pain.Results: Among 135 patients, 54.1% were categorized as having a low vitamin D level (< 30 nmol/L). On multivariable analysis, patients with a low 25-hydroxy-vitamin D (25[OH]D) level had a higher risk of postoperative moderate-severe pain (odds ratio, 2.44; 95% confidence interval, 1.181– 5.041; P = 0.016) when compared to patients with a sufficient 25(OH)D level. Static and dynamic pain scores at 3 months after surgery, as well as serum levels of CRP, IL-1, IL-6, and tumor necrosis factor-α were not significantly different between patients with low and sufficient 25(OH)D levels.Conclusion: Patients with low vitamin D levels are at a higher risk of acute moderate-severe pain after video-assisted thoracoscopic surgery.Trial Registration: http://www.chictr.org.cn, ChiCTR2100052380.Keywords: vitamin D, video-assisted thoracoscopic surgery, moderate-severe pain, chronic pain, inflammatory response

Background: Empyema Thoracis, a condition in which purulent fluid accumulates within the pleural cavity, is commonly caused by bacterial infection (both Gram-positive and Gram-negative), such as Mycobacterium tuberculosis, and rarely by fungal infection. Timely intervention significantly reduces morbidity and mortality. Surgical intervention is needed in advanced disease. This study aimed evaluate decortications performed through video-assisted thoracoscopic surgery (VATS) and open thoracotomy. Methods: This retrospective study included 47 patients who underwent decortications by either VATS or open thoracotomy for empyema Thoracis at the Department of Surgery of, BLDE DU Shri B M Patil Medical College from May 2015 to August 2020. Results: Tuberculosis was the most common etiological factor for empyema Thoracis. In 19 patients who underwent VATS decortications, VATS was converted to open thoracotomy in 11 patients. Only 8 patients achieved successful decortication with VATS. Thirty-nine patients (including 11 whose VATS was converted to open thoracotomy) underwent successful open thoracotomy decortications. Thirty-two patients had postoperative bronchopleural fistula, and all cases were successfully managed conservatively. The timing of the surgical intervention is critical in reducing morbidity and mortality. The more advanced the disease, the higher the failure rate of VATS in attaining complete decortications. Conclusion: Open thoracotomy decortication remains the gold standard in attaining complete decortications in advanced empyema Thoracis.

Video-assisted thoracoscopic surgery (VATS) stapler bullectomy can be performed with minimal morbidity. The residual cavities are frequently observed postoperatively, especially in cases with wide large bullae. We describe a technique using an exclusive thoracoscopic approach utilizing a polyglycolic-acid (PGA) sheet for preventing the postoperative residual cavities in a patient with a large bulla. A 40-year-old man was referred to our hospital for progressive shortness of breath. Chest computed tomography (CT) revealed multiple bullae in the upper lobe of left lung. A large bulla had compressed a significant volume of functional lung parenchyma; VATS stapler bullectomy was performed. This procedure excised no normal lung tissue and reduced the volume of the air-containing cavity with airtight repair. A PGA sheet inside the bulla reduced and prevented air leakage from the stapled margin. The patient was discharged and the postoperative course was uneventful. Compared with preoperative expiratory volume in 1 s (FEV1), postoperative FEV1 increased by 0.66 L. Postoperative chest CT 16 months after surgery demonstrated no air-containing cavity. At 38 months after surgery, the patient had no symptoms.

Abstract Background Systemic artery to pulmonary vessel fistula (SAPVF) is an uncommon abnormal vascular communication between systemic arteries and the lung parenchyma. It has been reported that the appropriate treatment for SAPVF is embolization or surgical resection. However, in patients such as ours, who have many aberrant vessels or multiple lesions, surgery should be considered as the first-choice treatment. Case presentation This case report describes multiple SAPVFs and huge bullae at the apex of the left lung in a 43-year-old man that were resected completely with the video-assisted thoracoscopic surgery (VATS). The patient had an uneventful postoperative recovery without any complications and was discharged 9 days postoperatively. He had heavy smoking history, and the giant bullae and the diffuse emphysematous change were found in the lung. Therefore, the chronic inflammation may have been present in the thoracic cavity, which caused multiple SAPVFs. Conclusions We describe the clinical course and management of the patient with multiple SAPVFs who had no obvious history of surgery, trauma, or various inflammatory or infection diseases. VATS should be the first-choice treatment in patients with many abnormal vessels or multiple lesions.

Background: Thoracoscopic lobectomy is a common treatment for congenital lung malformation. Single-direction thoracoscopic lobectomy may be an effective and safe approach without the need to flip the lung over repeatedly, thus minimizing tissue trauma, but its use has not been reported in children. The purpose of this study was to evaluate the safety and efficacy of single-direction thoracoscopic lobectomy in children. Methods: A total of 91 patients who underwent thoracoscopic lobectomy in our hospital from January 2020 to December 2020 were retrospectively analysed. According to the inclusion criteria, 21 children were identified as the single-direction group. The details of the single-direction thoracoscopic lobectomy technique are described. Another 21 patients who underwent conventional thoracoscopic lobectomy in the same period were matched using the propensity score matching and set as the control group, the clinical outcomes between the two groups were compared. Results: The median age of the patients was 4.72 months (4.72 ± 0.90) with a mean body weight of 7.43 kg (7.43 ± 1.14). There were no significant differences in intraoperative blood loss (P = 0.549), operation time (P = 0.859), length of chest tube drainage (P = 0.102) and length of hospital stay (P = 0.636) between the 2 groups. No patients experienced bronchopleural fistula and conversion to thoracotomy in either group. All patients recovered well without respiratory symptoms or other complications after follow-up of more than 1 year. Conclusions: Our preliminary experience presented a series of single-direction video-assisted thoracoscopic lobectomy for children with satisfactory perioperative results. [ABSTRACT FROM AUTHOR]

Objective: To compare the efficacy and safety of robotic-assisted thoracoscopic surgery (RATS) with video-assisted thoracoscopic surgery (VATS) in the treatment of mediastinal cysts. Methods: Retrospective analysis on clinical data of 70 cases of minimally invasive surgery for mediastinal cysts completed in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from April 2014 to December 2022. There were 34 cases in the RATS group with a cyst diameter of (3.70 ± 1.16) cm and 36 cases in the VATS group with a cyst diameter of (4.07 ± 1.20) cm. All cysts were evaluated preoperatively using magnetic resonance imaging (MRI) or chest computed tomography (CT) localization. Surgery-related indices were compared among the two groups. Results: All patients in two groups successfully completed resection of mediastinal cysts without perioperative deaths. Compared with the VATS group, the RATS group possessed shorter operative time [(75.32 ± 17.80) min vs. (102.22 ± 19.80) min, P < 0.001], lesser intraoperative bleeding [10 (5.00, 26.00) ml vs. 17.50 (5.00, 50.50) ml, P = 0.009], shorter postoperative chest drainage time [2 (1.00, 6.00) ml vs. 3 (2.00, 6.50) ml, P = 0.006] and shorter postoperative hospital stay [3 (2.00, 6.50) d vs. 4 (3.00, 7.50) d, P = 0.001]. There was no statistically significant discrepancy in intermediate openings and complications in both groups (P > 0.05). Conclusion: Compared with VATS, RATS is safety and effectivity in the treatment of mediastinal cysts and thus has advantages in operative time, intraoperative bleeding, postoperative chest drainage time and postoperative hospital stay.

Among the elderly, depression is one of the most common mental disorders, which seriously affects their physical and mental health and quality of life, and their suicide rate is particularly high. Depression in the elderly is strongly associated with surgery. In this study, we aimed to explore the risk factors and establish a predictive model of depressive symptoms 1 month after video-assisted thoracoscopic surgery (VATS) in elderly patients. The study participants included 272 elderly patients (age > 65 years) undergoing VATS from April 2020 to May 2021 at 1 of 18 medical centers in China. The patients were divided into a depression group and a nondepression group according to the Chinese version of the nine-item Patient Health Questionnaire (PHQ-9). The patients' pre- and postoperative characteristics and questionnaires were collected and compared. Then, binary logistic regression was used to determine the risk factors that affect postoperative depressive symptoms, and the predictive model was constructed. The prediction efficiency of the model was evaluated by drawing the receiver operating characteristic curve (ROC), and the area under the curve (AUC) was calculated to evaluate the value of the predictive model. Among all of the included patients, 16.54% (45/272) suffered from depressive symptoms after VATS. The results of the univariate analysis showed that body mass index (BMI), chronic pain, leukocyte count, fibrinogen levels, prothrombin time, ASA physical status, infusion volume, anxiety, sleep quality, and postoperative pain were related to postoperative depressive symptoms (all p < 0.05). The results of multivariate logistic regression analysis showed that a high fibrinogen level (OR = 2.42), postoperative anxiety (OR = 12.05), poor sleep quality (OR = 0.61), and pain (OR = 2.85) were risk factors of postoperative depressive symptoms. A predictive model was constructed according to the regression coefficient of each variable, the ROC curve was drawn, and the AUC value was calculated to be 0.889. The prediction model may help medical personnel identify older patients at risk of developing depressive disorders associated with VATS and may be useful for clinical purposes.

Objective To construct a prognostic prediction model for chronic postsurgical pain after video-assisted thoracoscopic surgery and develop a risk evaluation tool. Methods As a single-center prospective study, the study enrolled 1 132 patients received video-assisted thoracoscopic surgery between November 2020 and May 2021 at Peking Union Medical College Hospital. Numeric rating scale was used to assess the severity of acute pain when they were discharged and chronic pain at 6 months after surgery. Patients were divided into two groups based on the presence or absence of chronic postsurgical pain. Multivariate Logistic regression was conducted to analyze the risk factors which were used to construct prediction model and draw nomogram for chronic postsurgical pain after video-assisted thoracoscopic surgery. Results 460 patients (40.6%) were reported chronic pain at 6 months after surgery. More women and more patients with coronary heart disease belonged to the group of chronic postsurgical pain. Patients reported higher scores of numeric rating scale when they were discharged and inclined to keep taking painkiller after discharge. However, there were fewer patients with incisions fewer than 3 or using nitrous oxide during surgery in the group of chronic postsurgical pain (P＜0.05). The outcome of multivariate Logistic regression showed that the history of coronary heart disease, not using nitrous oxide in surgery, incisions more than or equal to 3, and the score of numeric rating scale on discharge were independent risk factors for chronic postsurgical pain (P＜0.05). The area under the receiver operator characteristic curve of the prediction model was 0.734. Conclusions The prediction model is conducive to clinical management for chronic postsurgical pain after video-assisted thoracoscopic surgery. [ABSTRACT FROM AUTHOR]

Objective To evaluate the short-term outcomes and postoperative inflammatory cytokine changes in patients with lung cancer treated with robot-assisted thoracoscopic surgery (RATS) versus video-assisted thoracoscopic surgery (VATS). Methods A total of 270 patients with lung cancer treated by minimally invasive surgery were selected for the study, and the surgical procedures were selected according to the patients’ economic conditions and preferences. Among them, 132 patients completed the operation through RATS, and 138 patients completed the operation through VATS. The clinical data of the two groups were compared. Results All patients successfully completed radical lung cancer surgery, and no perioperative deaths were reported. Intraoperative bleeding, postoperative drainage time, postoperative hospital stay, number of lymph nodes dissected, and number of lymph nodes dissected groups were more advantageous in the RATS group compared with the VATS group (P<0.05). In terms of operative time, total postoperative chest drainage, and hospitalization cost, the VATS group had an advantage (P<0.05). The postoperative levels of CRP, PCT, IL-6, IL-8, IL-10, and TNF-α increased in both groups, compared with preoperative levels, and the increases in the RATS group were lower than those in the VATS group. Conclusion RATS offers technical and short-term efficacy advantages for the treatment of lung cancer but comes with the disadvantage of high cost. Post-operative inflammatory cytokine elevation is lower in the RATS group, and inflammatory response to the organism is less severe. [ABSTRACT FROM AUTHOR]

Catamenial pneumothorax is a rare primary spontaneous pneumothorax associated with the menstrual phase and is the most common manifestation of thoracic endometriosis syndrome. We report a case of a 32‐year‐old woman with a history of endometriosis who presented to the emergency ward with a chief complaint of dyspnea and right‐sided chest pain, and a chest X‐ray showed a right pneumothorax. Initial management was by placing a chest tube to expand the right lung. The patient underwent a video‐assisted thoracoscopy and talc pleurodesis, during which we found multiple perforations in the tendinous part of the diaphragm. A partial resection of the tendinous part of the diaphragm was done. Our review indicated that primary spontaneous pneumothorax in women should be suspected as catamenial pneumothorax due to thoracic endometriosis. The gold standard procedure for diagnosis and treatment is surgery. Hormonal therapy is an effective choice to prevent and reduce post‐operative recurrence. [ABSTRACT FROM AUTHOR]

The superiority of segmentectomy over lobectomy with regard to preservation of pulmonary function is controversial. This study aimed to examine changes in pulmonary function after uniportal video-assisted thoracoscopic surgery (VATS) according to the number of resected segments. We retrospectively reviewed 135 consecutive patients who underwent anatomical lung resection via uniportal VATS from April 2015 to December 2020. Pulmonary function loss was evaluated using forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1). Patients were grouped according to number of resected segments: one-segment (n = 33), two segments (n = 22), three segments (n = 40), four segments (n = 15), and five segments (n = 25). Clinical characteristics did not significantly differ between groups, except for tumor size. Mean follow-up was 8.96 ± 3.16 months. FVC loss was significantly greater in five-segment resection (10.8%) than one-segment (0.97%, p = 0.008) and two-segment resections (2.44%, p = 0.040). FEV1 loss was significantly greater in five-segment resection (15.02%) than one-segment (3.83%, p < 0.001), two-segment (4.63%, p = 0.001), and three-segment resections (7.63%, p = 0.007). Mean FVC loss and FEV1 loss increased linearly from one-segment resection to five-segment resection. Mean loss in FVC and FEV1 per segment resected was 2.16% and 3.00%, respectively. Anatomical lung resection of fewer segments was associated with better preservation of pulmonary function in patients undergoing uniportal VATS, and function loss was approximately 2%–3% per segment resected with linear relationship.

Background: Common regional anesthesia approaches for video-assisted thoracoscopic surgery (VATS) include paravertebral block (PVB) and erector spinae plane block (ESPB). PVB is considered a deep nerve block which is contraindicated in antithrombotic therapy. ESPB is effective when administered as a bolus, as well as continuously. However, the recently proposed intertransverse process block (ITPB) ensures more effective diffusion of the local anesthetic into the paravertebral space. Case: We report cases of three patients who received bolus ITPB (costotransverse foramen block and mid-point transverse process-to-pleura block in one and two cases, respectively) combined with continuous ESPB when a deep nerve block could not be administered. Opioids were not required postoperatively, and all postoperative numerical rating scale scores (0–10) at rest were maintained below 4. Conclusions: The combination of bolus ITPB and continuous ESPB may be an alternative analgesic method when deep nerve blocks are contraindicated in VATS. [ABSTRACT FROM AUTHOR]

Background: Postoperative subcutaneous emphysema (SE) is a possible complication of thoracoscopic or laparoscopic surgery. This study investigated the risk factors and clinical significance of SE after video-assisted thoracoscopic surgery for esophageal cancer (VATS-e). Methods: This study included 135 patients who underwent VATS-e with artificial CO2 pneumothorax. Based on the X-ray images on the first postoperative day, patients were divided into two groups: N/L group (no SE or SE localized at the thoracic area, n = 65) and SE group (SE extended to the cervical area, n = 70). We compared clinicopathological features, surgical findings, and short-term outcomes between the two groups. Results: In SE group, there were more patients who received neoadjuvant chemotherapy compared to N/L group. SE group had significantly lower preoperative body mass index. SE group had more frequently two-lung ventilation than N/L group. Multivariate analysis demonstrated that low BMI, NAC, and two-lung ventilation were independent risk factors for SE extended to the cervical area. Although pulmonary complication was relatively frequent in SE group, there were no significant differences in surgical outcomes between two groups, and all patients had SE disappeared within 21 days without serious complications. Conclusions: Despite extension to the cervical area, SE had a modest impact on the short-term result of VATS-e with artificial CO2 pneumothorax. [ABSTRACT FROM AUTHOR]

Aims: Various ventilation strategies can be applied to prevent lung injury during one-lung ventilation (OLV). We compared intraoperative ventilation strategies in terms of haemodynamic and respiratory parameters in video-assisted thoracoscopic surgery (VATS). Methods: Sixty VATS patients, with American Society of Anesthesiologists score of I-III, receiving volume-controlled ventilation (VCV) (Group V) (n=30) or pressure-controlled ventilation (PCV) and recruitment maneuver (RM) (Group P) (n=30) were included in this prospective study. Mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), tidal volume (TV), airway pressures, compliance, and arterial blood gas values were recorded. In Group P, RM was applied after the 15th minute of OLV. The clinical efficacy and safety of VCV and PCV during VATS were evaluated. Results: The MAP and PaO2 were similar between groups throughout the follow-up (p>0.05). The peak inspiratory pressure (PIP) and Pplateau in Group V were higher than those in Group P (p<0.05). In Group P, there was an increase in TV, airway pressures, and compliance values at the 1st, 2nd, and 3rd minutes of RM (p<0.05). No significant change was observed in SpO2, PaO2, airway pressures, and compliance in Group P at post-RM 15th min (p>0.05). Conclusions: The ventilation modes did not have clinical superiority over each other. Nonetheless, lower PIP and Pplateau values found during PCV were considered advantage. In Group P, the RM applied during OLV increased compliance and TV. However, extensive research is needed to develop RM models that will ensure improvements in respiratory parameters will last longer.

Introduction: To date, no systematic review or meta-analysis study has been conducted regarding the use of video-assisted thoracoscopic surgery (VATS) in the removal of intrathoracic foreign bodies (FB). This systematic review aims to evaluate the feasibility of VATS in the removal of intrathoracic FBs. Methods: PubMed/MEDLINE, CINAHL, Web of Science, EMBASE, and Cochrane Library databases were systematically searched to identify reports published up to April 1, 2022. Results: The initial systematic search revealed a total of 208 papers, of which only 54 studies reporting 71 cases were included in this systematic review. Among the patients, 46 (64.8%) were male, 22 (31%) were female, and 3 (4.2%) were unknown. The mean age was 34.5 ± 24.3 years (1 day to 98 years). The patients were of 3 etiologic groups: iatrogenic (31, 43.7%), traumatic (28, 39.4%), and accidental (9, 12.7%). Most of the patients were emergency cases (27, 38%). The most frequently used imaging modalities to diagnose these foreign bodies were X-ray (46, 64.8%), followed by computed tomography (44, 62%), and ultrasonography (16, 22.5%). About 43% of all the foreign bodies were therapeutic equipment. The pleural cavity had the highest involvement (36.8%), followed by the lung parenchyma (14.6%) and thoracic cavity (13.2%). Regardless of the number of access ports, all the patients had a good clinical outcome. Conclusion: VATS is a safe and effective method for the removal of intrathoracic FBs from various thoracic sites that are associated with a good clinical outcome — in both elective and emergency cases.

Posterior dislocation of the sternoclavicular joint (SCJ), although uncommon, can be life-threatening. Displacement of the clavicular head poses a threat to the vital structures of the mediastinum. We describe the case of a 15-year-old boy with traumatic Salter Harris II medial clavicular fracture with posterior dislocation of the metaphysis resulting in impingement of the aortic arch, left subclavian and common carotid artery, as well as partial obstruction of the brachiocephalic vein. We describe the novel use of video-assisted thoracoscopy to assist with a safe open reduction and fixation of the fracture dislocation. The case highlights the importance of computer tomography imaging for diagnosis of posterior SCJ fracture/dislocations and the early recognition of potential life-threatening complications in the mediastinum.

Esophageal schwannomas are a subset of rare tumors that are difficult to differentiate from other esophageal tumors preoperatively. On endoscopic ultrasound (EUS), esophageal schwannomas generally appear as well-demarcated masses that are heterogeneous, hypoechoic, or mixed-echogenic in nature. We present a case of esophageal schwannoma with atypical EUS findings. EUS revealed two lobulated tumors that originated from the muscularis propria and characterized by heterogeneous hypoechoic features and poor blood flow signals. Right-sided video-assisted thoracoscopic surgery with esophageal tumor enucleation was performed. Immunostaining finally confirmed the diagnosis of an esophageal schwannoma. Esophageal schwannomas tend to show heterogeneous hypoechoic or mixed-echogenic features, but they rarely present with two lobulated masses.

Leiomyomas are the most common benign tumours of oesophageal smooth muscle origin. In this era of constantly evolving medical technology, video-assisted, robot-assisted and endoscopic approaches are the minimally invasive strategies for the excision of these lesions. Here, we report our modification of this surgery. The lesion was excised with uniportal video-assisted thoracoscopic surgery in a semi-prone position with single-lumen endobronchial intubation.

Abstract We performed a single-centre retrospective analysis using data from databases that were prospectively maintained in our centre between January 2019 and September 2021. Patients were divided into two groups based on the degree of pulmonary fissure completeness (PFC), using the fissure development scoring system. Patients with grades 2 or 3 PFC were considered to have incomplete pulmonary fissures and were included in Group A, and patients with grades 0 and 1 were considered to have complete pulmonary fissures and were included in Group B. The differences in demographics, perioperative characteristics and clinic outcomes between the two groups were evaluated. Multivariate logistic regression analysis was performed. A total of 213 patients with congenital lung malformation (CLM) underwent video-assisted thoracoscopic lobectomy. There were 30 patients in Group A and 183 patients in Group B. Our data showed that compared with Group B, Group A had a higher incidence of complications, especially Clavien-Dindo grade II and grade III complications. The degree of PFC was significantly correlated with the length of chest tube drainage and postoperative hospital stay. Multivariate logistic regression analysis showed that the degree of PFC could be used to predict the incidence of postoperative complications. Conclusions The degree of PFC is a predictor of the incidence of complications after thoracoscopic lobectomy in children with CLM.

In recent years, intrathoracic intercostal nerve block (INB) is regularly used thanks to its safety and accuracy, especially under the circumstance of lacking ultrasound or in face of the contraindications of the thoracic paravertebral block (TPVB). However, clinical evidence of comparing TPVB and INB for pain management after VATS has been limited and the observation of the chronic pain has been less than clear.Methods: A total of 180 patients undergoing VATS were randomly divided into three groups: A single multi-point paravertebral nerve block (Group P), intrathoracic intercostal nerve block (Group I), and general anesthesia without any regional block (Group C). Postoperative acute pain was scored at rest and coughing by the Visual Analog Scale (VAS) for recording 24h, 48h and 72h after VATS. All patients were interviewed 1, 3 and 6 months after the surgery to investigate both the incidence and intensity of chronic pains.Results: There were significantly less incidence and intensity of acute pain in Group P and Group I, compared to those in Group C. The patients in Group I showed the least incidence and intensity of chronic pain after 3 months compared with those in Group P and Group C. There are 89 of 98 patients suffering pains after 1 month, which grew into chronic pains after 3 months and 78 of them still suffered chronic pains even after 6 months.Conclusion: The intrathoracic INB offers excellent relief from acute and chronic pains, which does as effectively as TPVB. Besides, one-month postoperative pain could increase the risk of a chronic one.Keywords: video-assisted thoracoscopic surgery, acute pain, chronic pain, intrathoracic intercostal nerve block, paravertebral nerve block

Abstract The potential complications related to unplanned conversion to thoracotomy remains a major concern in thoracoscopic lobectomy and may limit the wide adoption of this strategy. We reviewed the literature from 1990 until February 2022, analyzing all papers comparing successful thoracoscopic lobectomy versus converted thoracoscopic lobectomy and/or upfront thoracotomy lobectomy to establish whether unplanned conversion negatively affected outcomes. Thirteen studies provided the most applicable evidence to evaluate this issue. Conversion to thoracotomy was reported to occur in up to 23% of cases (range, 5%–16%). Vascular injury, calcified lymph nodes, and dense adhesions were the most common reasons for conversion. Converted thoracoscopic lobectomy compared to successful thoracoscopic lobectomy was associated with longer operative time and hospital stay in all studies, with higher postoperative complication rates in seven studies, and with higher perioperative mortality rates in four studies. No significant differences were found between converted thoracoscopic lobectomy and upfront thoracotomy lobectomy. Five studies evaluated long‐term survival, and in all papers conversion did not prejudice survival. Surgeons should not fear unplanned conversion during thoracoscopic lobectomy, but to avoid unexpected conversion that may negatively impact surgical outcome, a careful selection of patients is recommended–especially for frail patients.

Abstract Objectives To investigate feasibility and safety of autologous blood in preoperative computed tomography (CT)-guided localization of pulmonary ground-glass nodules (GGNs) by comparing to mico-coil prior to video-assisted thoracoscopic surgery. Methods Clinical data of patients with GGNs who underwent video-assisted thoracoscopic surgery followed by preoperative CT-guided autologous blood or micro-coil localization was retrospectively reviewed in our department between September 2019 and November 2021. The localization duration, localization success rate, localization-related complication, localization cost, operation time, and conversion rate were compared between the 2 localization groups. Results Totally 65 patients with 65 GGNs were included in our study, with 34 patients in autologous blood group (group B) and 31 patients in micro-coil group (group M). There is no conversion to thoracotomy. The age, sex, nodule location, diameter of nodule and distance from the pleura between the 2 groups were statistically comparable. Compared with group M, group B had similar localization success rate (94.1% vs 83.9%, P = 0.183) but shorter localization time (14.50 ± 2.61 min vs 16.35 ± 2.30 min, P = 0.004), lower cost ($92.4 ± 3.2 vs $475.6 ± 8.5, P = 0.001), and lower incidence of puncture complications (3.0% vs 19.3%, P = 0.042). Conclusions The autologous blood localization is an effective and more economical method for preoperative GGNs localization, and is associated with fewer complications compared to micro-coil localization.

All patients received cSAPB postoperatively, and patients in Group RD received 20 mL of 0.375% ropivacaine plus 0.1 mg/kg dexamethasone followed by an infusion of 0.2% ropivacaine plus 0.02 mg/kg/hour dexamethasone at a rate of 5 mL/h in patient-controlled analgesia (PCA) pump. Patients in Group R received 20 mL of 0.375% ropivacaine with normal saline followed by an infusion of 5 mL/h of 0.2% ropivacaine in PCA pump. Fifty milligrams of tramadol was given as rescue medication when the visual analog scale (VAS) score was ≥ 4 at rest. The primary outcomes were the sum of pressing number within 48 hours postoperatively and the time to the first patient-controlled bolus. The secondary outcomes were VAS scores, the incidence of rescue analgesia, wound infection and nausea/vomiting.Results: Within 48 hours postoperatively, the sum of pressing number was more in Group R (18.33 ± 3.149 vs 16.09 ± 3.292, P = 0.006), and the Log Rank Test showed a significant difference in time to the first patient-controlled bolus (P = 0.006). After the PCA infusion finished, there were significantly lower VAS scores in Group RD at 60 and 72 hours postoperatively (P < 0.001). Additionally, the incidence of rescue analgesia in Group R was significantly more than that in Group RD (P < 0.001). No incision infection was observed in any patient.Conclusion: The cSAPB with ropivacaine plus dexamethasone prolonged the duration of analgesia and motor blockade, reduced pain intensity and rescued analgesia requirements after the end of PCA infusion for patients undergoing VATS, which provide further improvement to continuous perineural block.Keywords: continuous serratus anterior plane block, video-assisted thoracoscopic surgery, dexamethasone, levobupivacaine

Abstract Background Iatrogenic pneumothorax is the most frequent complication in preoperative CT‐guided localization (POCTGL) of lung nodules. We aimed to determine the predictive factors of iatrogenic pneumothorax. Methods We retrospectively analyzed data of consecutive POCTGL procedures in patients who received video‐assisted thoracoscopic surgery (VATS) at our hospital between May 2015 and October 2019. All of our patients utilized laser angle guide assembly to aid in the localization procedures. Results In 610 consecutive POCTGL procedures, 40 (6.6%) patients developed iatrogenic pneumothorax, and complications occurred in 8.5%. Univariate analyses revealed that puncture frequency, male gender, puncture depth, left decubitus position, and nodule near fissure were factors associated with pneumothorax, while multivariate analysis showed that only male gender (odds ratio 3.58, p = 0.012) and puncture frequency (odds ratio 2.39/time, p = 0.0004) determined development of pneumothorax. Further collective analysis on puncture frequency revealed that tumor in a difficult zone (1.33 ± 0.71 vs. 1.19 ± 0.45, p = 0.002), especially adjacent to the mediastinum (1.41 ± 0.75 vs. 1.21 ± 0.52, p = 0.002), angle difference of plan‐to‐practice (r = 0.209, p =

Background: The most objective of assessment in patients with undiagnosed pleural effusion is to set up early diagnosis and encourage treatment with minimal invasive procedure. Video-assisted thoracoscopic surgery (VATS) is regularly considered as gold standard examination for an undiagnosed pleural effusion with great diagnostic value. Objectives: This study was arranged to assess the role of (VATS) in the diagnosis of unexplained exudative pleural effusion. Patients and Methods: This is a retrospective study included all patients who underwent VATS for undiagnosed exudative pleural effusion patients from 2014 to 2020. Results: Total 105 patients who underwent VATS for undiagnosed pleural effusion in this time period as the diagnostic as well as therapeutic methods were included in the study. The overall mean age was 46.5± 20.71 and we had 51 Males (48.57%) and 54 Females (51.43%).There were 48 patients (54.29%) with co-morbidities most of them had diabetes mellitus (DM) in 36 patients (34.29%). The most common radiological findings were right free pleural effusion in 45 patients (42.86%) and pleural thickness in 42 patients (40%).VATS pleural drainage and biopsy (right and left) most common performed procedure in 75 patients (71.43%).Final histopathological diagnosis was nonspecific inflammation in 15 patients (14.29%), pleural TB in 57 patients(54.29%) and malignancy in 33patients (31.43%). Conclusion: VATS is a good diagnostic and therapeutic method. Therefore, patients had undiagnosed exudative pleural effusions should be underwent V

Background and objective Patients with pulmonary nodules are treated by minimally invasive surgery, and postoperative symptoms have become the main factors affecting patients' emotion and quality of life. This study aimed to analyze the changes of postoperative symptoms in lung cancer patients with pulmonary nodules. Methods The clinical data of eighty-eight lung cancer patients admitted to the same medical group of Department of Thoracic Surgery, West China Hospital of Sichuan University from June 2021 to September 2021 were prospectively collected and analyzed. The types and severity of clinical symptoms before operation, on discharge day, 30-day and 90-day after operation were analyzed. Results The incidence of postoperative symptoms in lung cancer patients was 79.5%, and most patients suffered from mild (54.3%) and moderate (32.9%) symptoms. The main postoperative symptoms of lung cancer patients were pain (55.7%) and cough (37.2%). The incidence of pain at discharge (55.7%) was significantly higher than that at 30-day (23.7%, P=0.01) and 90-day (12.0%, P=0.01) after discharge. The incidence of cough was significantly higher at 30-day (66.1%) and 90-day (66.0%) than that at discharge (37.2%) (P=0.01, P=0.04). Conclusion The main postoperative symptoms of lung cancer patients with pulmonary nodules are pain and cough. The incidence and severity of pain decreases with time, and the incidence of cough increases but the severity decreased gradually.

Abstract Introduction Malignant pleural effusions (MPEs) are common. MPE causes significant breathlessness and impairs quality of life. Indwelling pleural catheters (IPC) allow ambulatory drainage and reduce hospital days and re-intervention rates when compared to standard talc slurry pleurodesis. Daily drainage accelerates pleurodesis, and talc instillation via the IPC has been proven feasible and safe. Surgical pleurodesis via video-assisted thoracoscopic surgery (VATS) is considered a one-off intervention for MPE and is often recommended to patients who are fit for surgery. The AMPLE-3 trial is the first randomised trial to compare IPC (±talc pleurodesis) and VATS pleurodesis in those who are fit for surgery. Methods and analysis A multi-centre, open-labelled randomised trial of patients with symptomatic MPE, expected survival of ≥ 6 months and good performance status randomised 1:1 to either IPC or VATS pleurodesis. Participant randomisation will be minimised for (i) cancer type (mesothelioma vs non-mesothelioma); (ii) previous pleurodesis (vs not); and (iii) trapped lung, if known (vs not). Primary outcome is the need for further ipsilateral pleural interventions over 12 months or until death, if sooner. Secondary outcomes include days in hospital, quality of life (QoL) measures, physical activity levels, safety profile, health economics, adverse events, and survival. The trial will recruit 158 participants who will be followed up for 12 months. Ethics and dissemination Sir Charles Gairdner and Osborne Park Health Care Group (HREC) has approved the study (reference: RGS356). Results will be published in peer-reviewed journals and presented at scientific meetings. Discussion Both IPC and VATS are commonly used procedures for MPE. The AMPLE-3 trial will provide data to help define the merits and shortcomings of these procedures and inform future clinical care algorithms.

Abstract Background With the growing number of patients with coexisting pulmonary and mediastinal lesions detected, reports about simultaneous video-assisted thoracic surgery (VATS) for these concurrent diseases are still rare. To further explore the safety and effectiveness of simultaneous resection of pulmonary and mediastinal lesions by uniportal or biportal VATS, we retrospectively analyzed the clinical data of the largest series of cases to date. Methods From July 2018 to July 2021, all patients whose pulmonary lesions and mediastinal tumors were resected simultaneously in our institution were retrospectively reviewed. Their demographic and clinical data were collected and analyzed. Results A total of 54 patients were enrolled, of whom 44 underwent unilateral uniportal VATS, 3 underwent bilateral uniportal VATS and 7 underwent unilateral biportal VATS. Seven cases were converted to thoracotomy during surgery. For the remaining 47 patients with various demographic and clinical characteristics, most of the operations were completed within 3 h (n = 33, 70.2%) with blood loss of no more than 100 mL (n = 43, 91.5%). The duration of chest tube drainage was 5.66 ± 3.34 days, and the average daily volume was 196.90 ± 122.31 mL. Four cases of postoperative complications occurred during hospitalization. The length of postoperative hospital stay was 8.60 ± 3.63 days. No severe complications or deaths were observed during follow-up. Conclusions Uniportal and biportal VATS are safe and effective for simultaneous resection of selected coexisting pulmonary and mediastinal lesions, but the indications and operational details need more evaluation.

Abstract Background Intrathoracic gossypiboma is a consequence of retained sponge/swap, gauzoma, muslinoma, textiloma, or cottonoid in the thoracic cavity during surgery. The thoracic cavity is of the rarest place for gossypiboma as these entities most occur after abdominal surgery. Case presentation We report a case of intrathoracic gossypiboma that was missed for an extended period of time with no symptoms and was successfully treated with surgical intervention. Conclusions The rarity of gossypiboma necessitates a high index of suspicion for correct diagnosis. Gossypiboma is often difficult to diagnose, leading to misdiagnosis and unnecessary interventions. It is important to consider this entity as a diagnosis in any case with an unexplained or unusual presentation during the postoperative period.

Abstract Background Video-assisted thoracoscopic surgery (VATS) is an emerging technology in minimally invasive surgery, which has become recognized as standard treatments for early-stage lung cancer. Microcoil localization is considered to be a safe and effective way of preoperative localization, and is essential to facilitate VATS wedge-resection for lung nodules. Case presentation Here we report a rare case of a 28-year-old female who developed hemorrhagic shock caused by delayed pneumothorax after preoperative computed tomography (CT)-guided microcoil localization. The thoracic CT revealed hydropneumothorax in the right thoracic cavity at 10 h after microcoil localization, and the patient later had significant decreased hemoglobin level (87 g/L). Emergency thoracoscopic exploration demonstrated that the hemorrhagic shock was induced by delayed pneumothorax, which led to the fracture of an adhesive pleura cord and an aberrant vessel. Electrocoagulation hemostasis was then performed for the fractured vessel and the patient gradually recovered from the hypovolemic shock. Conclusions Microcoil localization is a relatively safe and effective way of preoperative localization of lung nodules, however, hemorrhagic shock could be induced by rupture of pleural aberrant vessels subsequent to puncture related pneumothorax. Shorten the time interval between localization and thoracoscopic surgery, extend the monitoring time after localization might help to reduce the risk of these complications.

Abstract Background The purpose of this retrospective study was to demonstrate the safety and feasibility of three-port single-intercostal video-assisted thoracoscopic surgery (SIC-VATS) segmentectomy compared to uniportal video-assisted thoracoscopic surgery (UVATS) segmentectomy. Methods We included 544 patients diagnosed with cT1N0M0 non-small-cell lung cancer (NSCLC) who underwent thoracoscopic segmentectomy between January 2020 and August 2021, including 147 and 397 patients who underwent three-port SIC-VATS and UVATS, respectively. After incorporating preoperative clinical variables, we compared surgical outcomes and perioperative indicators between the two groups by propensity score matching analysis. Results After 1:1 propensity score matching, each group comprised 143 patients with no significant differences in baseline demographics and characteristics. There was no significant difference in operative time (p = 0.469), blood loss (p = 0.501), number of dissected lymph nodes (p = 0.228), dwell time of the main chest drain (p = 0.065), hospital stay (p = 0.243), or major complication rate (p = 0.295) between the three-port SIC-VATS and UVATS groups. Conclusions The three-port SIC-VATS was as safe and feasible as UVATS for patients who are diagnosed with early-stage NSCLC.

Background: Pain is an everyday challenge during all surgeries and it is a chief postoperative complication, so pain management is a corner stone in anesthetic practice. Ultrasound guided nerve block is considered a recent technique for pain management. It provides better visualization of the nerves and reduces the risk for complications. Aim of the Work: The present study was designed to assess the analgesic efficacy of ultrasound guided Erector Spinae Plane Block done at the fifth thoracic transverse process level in patients undergoing VATS surgeries for postoperative analgesia. Patients and Methods: This prospective randomized clinical study was conducted in Ain Shams University Hospitals. It included a total of 60 adult patients aged 21-60 years, Scheduled for VATS surgeries. Patients were randomly divided into two equal groups 30 patients each. The ESPB group (n = 30): received ESPB after induction of anaethesia, while the Control group (n = 30): received only fentanyl 1- 2mcg/kg during induction of anesthesia and additional boluses of fentanyl.5 mcg/kg were given according to the patient's vital data. Results: The main finding in this study was that ultrasound guided ESPB provided a good analgesic effect in patients undergoing VATS surgery, it also reduced the need for rescue analgesia and the total amount of postoperative opioid consumption in comparison to controlled group, Prolonged the time to first request of analgesia, allowed early mobilization, Increase patient satisfaction in 1st 24 hour and Decrease incidence of nausea and vomiting. Conclusion: Ultrasound-guided erector spinae plane block was found statistically significantly in reducing postoperative opioid consumption, alleviating postoperative pain scores and improving patients' satisfaction in the first 24 hours after VATS surgeries, without associated adverse effects as postoperative nausea and vomiting, nerve injury, respiratory depression and hematoma formation.

BackgroundThis meta-analysis aimed to investigate the effectiveness and safety of minimally invasive surgery [MIS, including robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS)] and open thoracotomy (OT) for non-small cell lung cancer (NSCLC) patients with N2 disease.MethodsWe searched online databases and studies from the creation of the database to August 2022, comparing the MIS group to the OT group for NSCLC with N2 disease. Study endpoints included intraoperative outcomes [e.g., conversion, estimated blood loss (EBL), surgery time (ST), total lymph nodes (TLN), and R0 resection], postoperative outcomes [e.g., length of stay (LOS) and complication], and survival outcomes [e.g., 30-day mortality, overall survival (OS), and disease-free survival (DFS)]. We estimated outcomes using random effects meta-analysis to account for studies with high heterogeneity (I2 > 50 or p < 0.05). Otherwise, we used a fixed-effect model. We calculated odds ratios (ORs) for binary outcomes and standard mean differences (SMDs) for continuous outcomes. Treatment effects on OS and DFS were described by hazard ratio (HR).ResultsThis systematic review and meta-analysis of 15 studies on MIS vs. OT for NSCLC with N2 disease included 8,374 patients. Compared to OT, patients that underwent MIS had less estimated blood loss (EBL) (SMD = – 64.82, p < 0.01), shorter length of stay (LOS) (SMD = −0.15, p < 0.01), higher R0 resection rate (OR = 1.22, p = 0.049), lower 30-day mortality (OR = 0.67, p = 0.03), and longer overall survival (OS) (HR = 0.61, P < 0.01). The results showed no statistically significant differences in surgical time (ST), total lymph nodes (TLN), complications, and disease-free survival (DFS) between the two groups.ConclusionCurrent data suggest that minimally invasive surgery may provide satisfying outcomes, a higher R0 resection rate, and better short-term and long-term survival than open thoracotomy.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022355712.

Abstract Catamenial pneumothorax is a rare primary spontaneous pneumothorax associated with the menstrual phase and is the most common manifestation of thoracic endometriosis syndrome. We report a case of a 32‐year‐old woman with a history of endometriosis who presented to the emergency ward with a chief complaint of dyspnea and right‐sided chest pain, and a chest X‐ray showed a right pneumothorax. Initial management was by placing a chest tube to expand the right lung. The patient underwent a video‐assisted thoracoscopy and talc pleurodesis, during which we found multiple perforations in the tendinous part of the diaphragm. A partial resection of the tendinous part of the diaphragm was done. Our review indicated that primary spontaneous pneumothorax in women should be suspected as catamenial pneumothorax due to thoracic endometriosis. The gold standard procedure for diagnosis and treatment is surgery. Hormonal therapy is an effective choice to prevent and reduce post‐operative recurrence.

Introduction: There is no consensus on postoperative thoracostomy tube management in thoracic patients, specifically whether or not a chest radiograph is required after tube removal. Methods: Retrospective review of video-assisted thoracoscopic (VATS) lobectomy patients was performed at a large tertiary referral center from January 1, 2019 to December 31, 2020. Patients were grouped as asymptomatic or symptomatic after thoracostomy removal. Demographic data and clinical outcomes were evaluated. Descriptive statistics, Fisher's exact and Wilcoxon rank sum tests were performed. Results: 202 of 208 patients were asymptomatic after thoracostomy removal. Demographic data between those who were asymptomatic and symptomatic revealed no differences except for a higher FEV1/FVC in the asymptomatic group. Median length of stay for asymptomatic and symptomatic patients was 2.0 and 3.5 (p=0.295). 62% of asymptomatic versus 100% of symptomatic patients had abnormal post-pull radiographs (p=0.088). No one in the asymptomatic group required an intervention after thoracostomy removal and prior to discharge whereas 66.7% in the symptomatic group required a procedure (p

Background: Rib fractures are a common injury in trauma. Potential complications include pain, pneumonia, respiratory failure, disability, and death. Surgical stabilization of rib fractures (SSRF) has become an available treatment option, and complete video-assisted thoracoscopic surgery (VATS) for SSRF is gradually accepted because of minimally invasive and pain relief. To our knowledge, complete uni-port VATS for SSRF has not yet been reported. Case presentation: A 53-year-old man accidentally fell off a three-meter high scaffolding while working resulting in severe chest pain and shortness of breath. He was found with left 7th through 11th rib fractures with a pulmonary contusion from computed tomography (CT). A 4 cm incision was made in the 7th intercostal space in the midaxillary line, and complete uni-port VATS for SSRF were operated. The patient's pain was significantly relieved after the operation, and the scar was tiny and unapparent. Conclusions: Complete uni-port VATS for SSRF is a novel and modificatory method of operation with the benefit of minimal invasion, meanwhile, intrathoracic injuries could be treated at the same time. Further study is warranted. [ABSTRACT FROM AUTHOR]

Purpose: Research has shown that a higher dose of bupivacaine administered in continuous paravertebral block (CPVB) provides a greater analgesic effect after video-assisted thoracoscopic surgery (VATS). In this randomized, controlled, double-blind study, we hypothesized that 0.25% 8 ml/h of levobupivacaine administered in CPVB after VATS provides a greater analgesic effect than 0.125% 8 ml/h. Methods: Fifty patients who underwent unilateral VATS were randomized to receive a postoperative continuous infusion of 0.125% (low group, n = 25) or 0.25% (high group, n = 25) levobupivacaine at 8 mL/h for CPVB. The primary outcome was the visual analog scale (VAS) score during coughing on the morning of postoperative day (POD) 1. The secondary outcomes were the VAS scores at rest and during coughing on POD 2, the number of anesthetized dermatomes, the frequency of rescue analgesics, postoperative nausea and vomiting, patient satisfaction, and adverse events and complications. Results: There was no significant difference in the VAS score during coughing on the morning of POD 1 between the low and high groups [median, 37.5 (interquartile range 21–50) vs. 40.0 (interquartile range 21–50), respectively; p = 0.79]. Similarly, there were no significant differences in any secondary outcomes between the two groups. Conclusions: Levobupivacaine at 0.25% 8 ml/h in CPVB did not provide better analgesia after VATS over 0.125% 8 ml/h. Clinical trial registration number: UMIN000037930 [ABSTRACT FROM AUTHOR]

Introduction: Determining the prevalence of chronic postsurgical pain (CPSP) after video-assisted thoracoscopic surgery (VATS) and identifying CPSP predictors should improve the prognosis of patients undergoing VATS. Although several studies have investigated predictors of CPSP after VATS, there were significant dissimilarities in the findings due to the confounding of predictors. Methods: PubMed, Cochrane, MEDLINE, Web of Science, Chinese Biomedical Literature, and China National Knowledge Infrastructure databases were comprehensively searched using the Medical Subject Headings terms "pain, postoperative," "thoracic surgery, video-assisted," and all related free terms from inception until March 27, 2022. The Stata metaprop package was used to comprehensively analyze the incidence of CPSP following VATS. Furthermore, the pooled odds ratios (OR) or the standardized mean differences (SMD) and their corresponding 95% confidence intervals (95% CI) were calculated, and qualitative analyses were performed for predictors that could not be assessed quantitatively to evaluate the effects of the included risk factors on the occurrence of CPSP. Unadjusted odds ratios were utilized to consider the impact of non-significant estimates if the original study did not report them. Results: Of the 4302 studies, 183 were considered eligible, and 17 were finally included in this study. The overall incidence of CPSP after VATS was 35.3% (95% CI 27.1–43.5%). The qualitative synthesis results revealed that female sex, age, and acute postoperative pain were definite predictors of CPSP after VATS. The number of ports, operation time, duration of drainage, and insufficient analgesia were also considered predictors. Consistent, quantitative synthesis results also showed that the aforementioned predictors were closely related to the occurrence of CPSP after VATS. Only by quantitative analysis, postoperative chemotherapy and an educational level less than junior school were also risk factors for CPSP. Other predictors displayed no evidence or unclear evidence of association with CPSP after VATS. Conclusion: This study preliminarily determined the incidence of CPSP after VATS based on the existing literature. Female sex, age, and acute pain were identified as risk factors for CPSP after VATS, and other potential risk factors were also identified and analyzed. However, as a result of the inclusion of retrospective studies and inevitable limitations in this systematic review and meta-analysis, the results of this study still need to be verified by large-scale prospective clinical studies.

Background and Objectives: Ipsilateral shoulder pain (ISP) is a common complication after thoracic surgery. Severe ISP can cause ineffective breathing and impair shoulder mobilization. Both phrenic nerve block (PNB) and suprascapular nerve block (SNB) are anesthetic interventions; however, it remains unclear which intervention is most effective. The purpose of this study was to compare the efficacy and safety of PNB and SNB for the prevention and reduction of the severity of ISP following thoracotomy or video-assisted thoracoscopic surgery. Materials and methods: Studies published in PubMed, Embase, Scopus, Web of Science, Ovid Medline, Google Scholar and the Cochrane Library without language restriction were reviewed from the publication's inception through 30 September 2022. Randomized controlled trials evaluating the comparative efficacy of PNB and SNB on ISP management were selected. A network meta-analysis was applied to estimate pooled risk ratios (RRs) and weighted mean difference (WMD) with 95% confidence intervals (CIs). Results: Of 381 records screened, eight studies were eligible. PNB was shown to significantly lower the risk of ISP during the 24 h period after surgery compared to placebo (RR 0.44, 95% CI 0.34 to 0.58) and SNB (RR 0.43, 95% CI 0.29 to 0.64). PNB significantly reduced the severity of ISP during the 24 h period after thoracic surgery (WMD −1.75, 95% CI −3.47 to −0.04), but these effects of PNB were not statistically significantly different from SNB. When compared to placebo, SNB did not significantly reduce the incidence or severity of ISP during the 24 h period after surgery. Conclusion: This study suggests that PNB ranks first for prevention and reduction of ISP severity during the first 24 h after thoracic surgery. SNB was considered the worst intervention for ISP management. No evidence indicated that PNB was associated with a significant impairment of postoperative ventilatory status. [ABSTRACT FROM AUTHOR]

Background: This study aimed to compare early results in patients who underwent subxiphoid wedge resection with those operated on using a multiportal approach. Methods: We retrospectively evaluated 151 patients who underwent diagnostic wedge resection for suspected interstitial lung disease. Patients who underwent wedge resection via subxiphoid video-assisted thoracoscopic surgery and conventional video-assisted thoracoscopic surgery were compared. Results: The study included 90 men (59.6%) and 61 women (40.4%) with a mean age of 54.8 ± 12 years. Of these, 127 patients underwent conventional video-assisted thoracoscopic surgery and 24 patients underwent subxiphoid video-assisted thoracoscopic surgery. Postoperative complications occurred in 13 patients (8.6%), with no significant difference according to surgical technique. Sex was a significant factor in the rate of complications (12.2% in men vs. 3.2% in women). There was no intraoperative mortality; the 30-day mortality rate was 4% (n = 6). Five nonsurviving patients were in the conventional video-assisted thoracoscopic surgery group and 1 was in the subxiphoid video-assisted thoracoscopic surgery group (p = 0.95). Conclusion: The results of this study indicate that the subxiphoid approach reduced procedure time and length of hospital stay in the early period, while there was no significant difference between the techniques in terms of complications or mortality. Based on these findings, we conclude that surgical outcomes were as successful with the subxiphoid approach as with conventional video-assisted thoracoscopic surgery. [ABSTRACT FROM AUTHOR]

Background: Video‐assisted thoracoscopic surgery (VATS) is the preferred treatment for resectable non‐small cell lung cancer. The increased survival of patients after a first operation has caused increases in the incidence of locoregional recurrence or second primary lung cancer and a concomitant increase in the number of patients who require secondary surgery. Ipsilateral secondary operation is also commonly practiced, albeit with enhanced difficulty. Therefore, it is necessary to evaluate the feasibility and safety of VATS for ipsilateral lung cancer after pulmonary resection. Methods: Patients who underwent ipsilateral secondary VATS in the West China Hospital, Sichuan University from 2012 to 2021 were assessed retrospectively. All included patients had a pulmonary resection. Clinical characteristics, perioperative outcomes, and survival data were collected, with an emphasis on conversion to thoracotomy, postoperative complications, 30‐day mortality, and survival. Logistic regression analysis was used to identify predictors of postoperative complications. Results: Seventy patients were enrolled, of which 10 (14.3%) had converted thoracotomy, 17 (24.3%) had postoperative complications, and two (2.9%) had grade III complications. No patient died within 30 days after surgery. High Charlson comorbidity index (CCI) and severe pleural adhesion were independent predictors for complications. The median follow‐up was 50 months (range: 3–120), and the 5‐year overall survival was 78.2%. Conclusion: Secondary VATS for ipsilateral lung cancer for patients who had pulmonary resection was feasible and safe. Strict preoperative evaluation and careful management of pleural adhesion are crucial for the success of the surgery. [ABSTRACT FROM AUTHOR]

Background: Stage III tuberculous empyema is a common disease of tuberculosis. Traditionally, it has been treated by thoracotomy or video-assisted thoracoscopic surgery with two to four incisions. But conventional surgery has large trauma, large bleeding volume and long recovery time. To our knowledge it is the first report of surgery for stage III tuberculous empyema with a mini single-port approach. Case presentation: A 23-year-old woman admitted to our hospital with complaints of intermittent chest pain for half a year. We got the diagnosis of stage III tuberculous empyema after medical treatment. Considering that the patient was young and unmarried, we decided to perform minimally invasive pleural decortication through a 2.5 cm single port. The operation time was 240 min, and blood loss was 100 ml. The patient recovered well and postoperative pain was mild. Conclusion: This case demonstrates that single-port VATS with a smaller incision for the Stage III tuberculous empyema should be considered in well selected patients. [ABSTRACT FROM AUTHOR]

Thymectomy is a well-established therapeutic option in the multidisciplinary treatment of nonthymomatous myasthenia gravis (MG) and in thymoma treatment. Although many surgical procedures for thymectomy have been identified, the transsternal method is still regarded as the gold standard. Minimally invasive procedures, on the other hand, have achieved popularity in the last decades and are now extensively used in this field of surgery. Among them, robotic thymectomy has been the most cutting- edge surgical procedure. Several authors and meta-analyses have shown that a minimally invasive approach to thymectomy is associated with improved surgical results and fewer complications in surgery compared to transsternal open thymectomy, without any substantial changes in myasthenia gravis complete rates of remission. Hence, in the present review of the literature, we aimed to describe and delineate the techniques, advantages, outcomes, and future perspectives of robotic thymectomy. Existing evidence suggests that robotic thymectomy will likely become the gold standard for thymectomy in early stage thymomas and MG subjects. Many of the drawbacks related to other minimally invasive procedures appear to be resolved by robotic thymectomy, and long-term neurological outcomes are satisfactory. In addition, improved vision and high dexterity of instrument movements enable safe and complete thymic tissue dissection, superior to standard thoracoscopic procedures. The access with minimally invasive surgery VATS (video-assisted thoracoscopic surgery) or RATS (robot-assisted thoracic surgery) access in its various variants allows the extent of mediastinal fat resection due to the possibility of ectopic thymic foci in the mediastinum determining the long-term outcome in the group of patients operated on for myasthenia gravis. However, it was recommended to carry out better designed, multi-centre, randomized studies to arrive at definitive conclusions on robotic thymectomy for thymomas and myasthenia gravis treatment.
