Right anterior mini thoracotomy for redo cardiac surgery: case series from North America and Europe.

Background: Right anterior mini thoracotomy (RAMT) for aortic valve replacement (AVR) is a minimally invasive procedure that avoids sternotomy. Herein, we report the outcomes of patients who underwent redo-cardiac via a RAMT approach for AVR. Methods: This case series reports the clinical outcomes of 14 consecutive redo operations, done in Calgary (Canada) and Gdansk (Poland) between 2020 and 2023. Primary outcomes were 30-day mortality and disabling stroke. Secondary outcomes included surgical times, hemodynamics, permanent pacemaker implantation (PPM), length of ICU and hospital stay, new post-operative atrial fibrillation (POAF), post-operative blood transfusion, incidence of acute respiratory distress syndrome (ARDS), rate of continuous renal replacement therapy (CRRT) and/or dialysis, and chest tube output in the first 12-hours after surgery. Results: Nine patients were male, and the mean age was 64.36 years. There were no deaths, while one patient had a disabling stroke postoperatively. Mean cardiopulmonary bypass and cross clamp-times were 136 min and 90 min, respectively. Three patients needed a PPM, 3 patients needed blood transfusions, and 2 developed new onset POAF. Median lengths of ICU and hospital stays were 2 and 12 days, respectively. There was no incidence of paravalvular leak greater than trace and the average transvalvular mean gradient was 12.23 mmHg. Conclusion: The number of patients requiring redo-AVR is increasing. Redo-sternotomy may not be feasible for many patients. This study suggests that the RAMT approach is a safe alternative to redo-sternotomy for patients that require an AVR.

The Enigma of Recurrent Lung Abscess: Management and Outcomes in a School-Aged Child With a Review of Literature.

Pediatric lung abscess is a rare and poorly studied disease entity. In the past, prolonged courses of intravenous (IV) antibiotics have been successfully used; however, with the advent of interventional radiology, the main therapeutic approach is through percutaneous placement of pigtail catheters with ultrasound and computed tomography (CT) direction, where available. The pathogen yield identified from fluid samples of the abscess has dramatically increased owing to the greater invasive measures, such as aspiration and drainage, as well as enhanced microbiological diagnostic methods, which also include polymerase chain reaction testing. In our case report, in 2012 when the patient was two years old, she was diagnosed with pulmonary Koch's and underwent anti-Koch's therapy, category 2. High-resolution CT of the chest revealed a large lobulated cavitary lesion with an air-fluid level suggestive of a right lung abscess. After initial therapy with IV antibiotics for three weeks and a negative tuberculosis work-up, she underwent right limited lateral thoracotomy and drainage with decortication of the right lung abscess (LA) in 2019 via a left endobronchial tube with a bronchial blocker (general endobronchial anesthesia). All samples sent for histopathologic examination after surgery yielded negative results, and she was discharged after a course of injectable antibiotics for 21 days. She remained almost symptom-free for the next four years. Thereafter, she presented with a right LA recurrence due to a thick-walled cavitary lesion, with a severely damaged right lower lung lobe resulting in right lower lobectomy under single-lung ventilation (double-lumen endotracheal tube No. 26 Fr.). Culture results should guide management, particularly for immunocompromised patients, as the LA may be attributed to complications arising from underlying conditions. Primary lung abscesses (PLA) in children are typically caused by Staphylococcus aureus, Streptococcal species, and Klebsiella pneumoniae. Compared to adults, children with PLA and secondary lung abscesses have a meaningfully greater rate of recovery.

Lymph node dissection in lung cancer surgery: a comparison between robot-assisted vs. video-assisted thoracoscopic approach.

Background: TNM staging is the most important prognosticator for non-small cell lung cancer (NSCLC) patients. Staging has significant implications for the treatment modality for these patients. Lymph node dissection in robot-assisted thoracoscopic (RATS) surgery remains an area of ongoing evaluation. In this study, we aim to compare lymph node dissection in RATS and VATS approach for lung resection in NSCLC patients. Methods: We retrospectively compiled a database of 717 patients from July 31, 2015-July 7, 2022, who underwent either a wedge resection, segmentectomy or lobectomy. We analysed the database according to lymph node dissection. The database was divided into RATS (n = 375) and VATS (n = 342) procedures. Results: The mean number of lymph nodes harvested overall with RATS was 6.1 ± 1.5 nodes; with VATS approach, it was 5.53 ± 1.8 nodes. The mean number of N1 stations harvested was 2.66 ± 0.8 with RATS, 2.36 ± 0.9 with VATS. RATS approach showed statistically higher lymph node dissection rates compared to VATS (p = 0.002). Out of the 375 RATS procedures, 26 (6.4%) patients undergoing a RATS procedure were upstaged from N0/N1 staging to N2. N0/N1-N2 upstaging was reported in 28 of 342 (8.2%) patients undergoing a VATS procedure. The majority of upstaging was seen in N0-N2 disease: 19 of 375 (5%) for RATS and 23 of 342 (6.7%) for VATS. Conclusions: We conclude that in RATS procedures, there is a higher rate of lymph node dissection compared to VATS procedures. Upstaging was mostly seen in N0-N2 disease, this was observed at a higher rate with VATS procedures.

Minimally invasive approaches versus conventional sternotomy for aortic valve replacement in patients with aortic valve disease: a systematic review and meta-analysis of 17 269 patients.

Background: Aortic valve replacement (AVR) is a common procedure for aortic valve pathologies, particularly in the elderly. While traditional open AVR is established, minimally invasive techniques aim to reduce morbidity and enhance treatment outcomes. The authors' meta-analysis compares these approaches with conventional sternotomy, offering insights into short and long-term mortality and postoperative results. This study provides valuable evidence for informed decision-making between conventional and minimally invasive approaches for AVR. Materials and methods: Till August 2023, PubMed, Embase, and MEDLINE databases were searched for randomized controlled trials (RCT) and propensity score matched (PSM) studies comparing minimally invasive approaches [mini-sternotomy (MS) and right mini-thoracotomy (RMT)] with full sternotomy (FS) for AVR. Various outcomes were analyzed, including mortality rates, bypass and clamp times, length of hospital stay, and complications. Risk ratios (RR) and the weighted mean differences (WMD) with corresponding 95% CIs were calculated using Review Manager. Results: Forty-eight studies were included having 17 269 patients in total. When compared to FS, there was no statistically significant difference in in-hospital mortality in MS (RR:0.80; 95% CI:0.50-1.27; I2=1%; P=0.42) and RMT (RR:0.70; 95% CI:0.36-1.35; I2=0%; P=0.29). FS was also linked with considerably longer cardiopulmonary bypass duration than MS (MD:8.68; 95% CI:5.81-11.56; I2=92%; P=0.00001). The hospital length of stay was determined to be shorter in MS (MD:-0.58; 95% CI:-1.08 to -0.09; I2=89%; P=0.02) with no statistically significant difference in RMT (MD:-0.67; 95% CI:-1.42 to 0.08; I2=84%; P=0.08) when compared to FS. Conclusions: While mortality rates were comparable in minimally invasive approaches and FS, analysis shows that MS, due to fewer respiratory and renal insufficiencies, as well as shorter hospital and ICU stay, may be a safer approach than both RMT and FS.

Different approach, similar outcomes: the impact of surgical access routes in minimally invasive cardiac surgery on enhanced recovery after surgery.

Objectives: Enhanced recovery after surgery (ERAS) is a growing phenomenon in all surgical disciplines and aims to achieve a faster functional recovery after major operations. Minimally invasive cardiac surgery (MICS) therefore integrates well into core ERAS values. Surgical access routes in MICS include right anterolateral mini-thoracotomy (MT) as well as partial upper mini-sternotomy (PS). We seek to compare outcomes in these two cohorts, both of which were enrolled in an ERAS scheme. Methods: 358 consecutive patients underwent MICS and perioperative ERAS at our institution between 01/2021 and 03/2023. Patients age >80 years, with BMI > 35 kg/m², LVEF ≤ 35%, endocarditis or stroke with residuum were excluded. Retrospective cohort analysis and statistical testing was performed on the remaining 291 patients. The primary endpoint was successful ERAS, secondary endpoints were the occurrence of major bleeding, ERAS-associated complications (reintubation, return to ICU) as well as access-related complications (wound infection, pleural and pericardial effusions). Results: 170 (59%) patients received MT for mitral and/or tricuspid valve surgery (n = 162), closure of atrial septal defect (n = 4) or resection of left atrial tumor (n = 4). The remaining 121 (41%) patients had PS for aortic valve repair/replacement (n = 83) or aortic root/ascending surgery (n = 22) or both (n = 16). MT patients' median age was 63 years (IQR 56-71) and 65% were male, PS patients' median age was 63 years (IQR 51-69) and 74% were male. 251 (MT 88%, PS 83%, p = 0.73) patients passed through the ERAS program successfully. There were three instances of reintubation (2 MT, 1 PS), and three instances of readmission to ICU (2 MT, 1 PS). Bleeding requiring reexploration occurred six times (3 MT, 3 PS). There was one death (PS), one stroke (MT), and one myocardial infarction requiring revascularization (MT). There were no significant differences in any of the post-operative outcomes recorded, except for the incidence of pericardial effusions (MT 0%, PS 3%, p = 0.03). Conclusions: Despite different surgical access routes and underlying pathologies, results in both the MT and the PS cohort were generally comparable for the recorded outcomes. ERAS remains safe and feasible in these patient groups.

Recognition of an extralobar pulmonary sequestration during lung resection.

BACKGROUND: Extralobar pulmonary sequestration is located outside the lung parenchyma and is covered by a separated pleural sac, which comprises approximately 25% of all pulmonary sequestration. CASE PRESENTATION: This article reported one case of an extralobar pulmonary sequestration originated from the mesoesophagus, which was recognized and excised during a lung resection. Histologic examination revealed an ectopic lung tissue with hyperplasia of bronchioles, which was accord with an extralobar pulmonary sequestration. CONCLUSIONS: CT angiogram, ultrasound and MRI can be used to clarify the diagnosis and detect the abnormal feeding arteries of extralobar pulmonary sequestration. Carefulness should be taken while dissecting and ligating the potential feeding arteries. Endovascular occlusion might be an alternative option to surgery.

Left anterior mini-thoracotomy: an alternative approach for pulmonary valve replacement after surgically corrected tetralogy of fallot.

INTRODUCTION: Pulmonary regurgitation (PR) remains a common sequela in patients following surgically corrected TOF, and may lead to progressive right ventricle dilatation and dysfunction. The conventional approach of redo-sternotomy for pulmonary valve replacement (PVR) is associated with increased operative time as well as risks of bleeding and injury to the heart and great vessels. Thus, left anterior mini-thoracotomy has become an alternative approach in eliminating the risks of redo-sternotomy in these patients. This series aimed to determine the outcomes of minimally invasive pulmonary valve replacement after surgical TOF correction. METHODS: A retrospective analysis was conducted on 24 patients with severe PR post-surgical TOF correction who underwent left anterior mini-thoracotomy PVR in Penang General Hospital from January 2021 to January 2023. RESULTS: The median age was 23.5 years (I.Q.range 17.6-36.3), with a male:female ratio of 1:4. Majority of patients had mild to moderate symptoms prior to surgery and 19 patients (79.1%) were on regular diuretics medication. All patients had severe free-flow PR with evidence of right ventricular dilatation and dysfunction. Magnetic Resonance Imaging and computed tomography of pulmonary artery were performed prior to surgery. Minimally invasive PVR was performed on all patients via left upper anterior mini-thoracotomy and femoral-femoral bypass without cardioplegic arrest. The operative time and cardiopulmonary bypass time were 208 (I.Q.range 172-324) and 98.6 minutes(I.Q.range 87.4-152.4) respectively. The time to wean off inotropes postoperatively was 6.2 hours (I.Q.range1.4-14.8), and no postoperative arrhythmia and chest re-exploration were reported. Most patients stayed in Intensive Care Unit (ICU) for 10.8 hours (I.Q.range 8.4-36.5), and the total hospital stay was 4.2 days (I.Q.range 3.4-7.6). 2 patients (11.1%) required blood transfusion postoperative. There was no paravalvular leak and no mortality during the follow-up period of up to 28 months. CONCLUSION: Minimally invasive PVR after surgical correction of TOF is a safe alternative to the conventional redo-sternotomy approach in patients with favorable anatomy. This approach is able to reduce the risks associated with redo-sternotomy, particularly bleeding and injury to mediastinal structures, with the additional benefit of expedited recovery and hospital discharge. Our series has shown a safe and efficient approach in these patients with favorable outcomes.

Needle aspiration versus tube thoracostomy in patients with symptomatic primary spontaneous pneumothorax: an updated meta-analysis of randomized controlled trials.

Primary spontaneous pneumothorax (PSP) is an important disease commonly seen in young males. While incidentally diagnosed cases can be managed conservatively, symptomatic patients often necessitate intervention. Chest tube placement (tube thoracostomy) is commonly used, at least in the USA as a primary treatment modality, which requires hospitalization. On the other hand, needle aspiration (NA) has been widely adopted due to simplicity and reported efficacy and safety. No consensus is reached regarding superiority and/or preferred modality, with a lack of guidelines agreement. Therefore, we conducted an updated meta-analysis of randomized controlled trials comparing NA to tube thoracostomy in patients with symptomatic PSP. Prespecified outcomes were immediate success rate, 12-month recurrence rate, post intervention complications rate, and hospital length of stay. We identified and pooled data from six randomized trials, with a total of 759 patients and a median follow up of 12 months. Our analysis showed that NA and tube thoracostomy have similar immediate success rate and 12-month recurrence rate. We also found that NA has less complication rate, need for surgical intervention, and less hospital stays. In conclusion, our review showed that in symptomatic patients with PSP, NA is as effective as tube thoracostomy regarding immediate success rate and 12-month recurrence rate, with the added benefit of less complications rate and need for surgical intervention.

Pain management after thoracotomy with dexamethasone and bupivacaine through a peripleural cather: a randomized controlled trial.

INTRODUCTION: Thoracotomy procedures can result in significant pain and cause nausea/vomiting. Glucocorticoids have anti-emetic and analgesic effects due to their anti-inflammatory and nerve-blocking properties. This study investigates the additive effect of local dexamethasone with bupivacaine as sole analgesic medication through a peripleural catheter after thoracotomy. METHOD: The study was conducted as a randomized control trial on 82 patients. Participants were allocated to receive either 2.5 mg/kg of bupivacaine plus 0.2 mg/kg of dexamethasone or 2.5 mg/kg of bupivacaine plus the same amount of normal saline as placebo through a 6 French peripleural catheter implemented above the parietal pleura and beneath the musculoskeletal structure of the chest wall. The primary outcome was the severity of pain 24 h after the operation in the visual analogue scale (VAS) score. Secondary outcomes were the incidence of nausea/vomiting, opioid consumption for pain control, and incidence of any adverse effects. RESULTS: A total of 50 participants were randomized to each group, and the baseline characteristics were similar between the groups. Median of VAS score (6 (3-8) vs. 8 (6-9), p < 0.001), postoperative opioid consumption (9 (36%) vs. 17 (68%) patients, p=0.024), and median length of hospital stay (4 (3-8) vs. 6 (3-12) days, p < 0.001) were significantly lower in the dexamethasone group. However, postoperative nausea/vomiting (p=0.26 for nausea and p=0.71 for vomiting) and surgical site infection (p = 0.55) were similar between the two groups. CONCLUSION: In thoracotomy patients, administering local dexamethasone + bupivacaine through a peripleural catheter can reduce postoperative pain, analgesic consumption, and length of hospital stay.

Final Lifelines: The Implications and Outcomes of Thoracic Damage Control Surgeries.

INTRODUCTION: There is a lack of data on the outcomes of thoracic damage control surgery (TDCS). This study aimed to describe the characteristics and outcomes of patients undergoing TDCS. METHODS: This is a retrospective analysis of the American College of Surgeons-Trauma Quality Improvement Program database (2017-2021). All trauma patients who underwent emergency thoracotomy and packing with temporary closure were included. Patients were stratified based on the age groups (pediatric [<18 y], adults [18-64 y], and older adults [≥65 y]). Our primary outcome measures included 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. RESULTS: We identified 14,192 thoracotomies, out of which 213 underwent TDCS (pediatric [n = 17], adults [n = 175], and older adults [n = 21]). The mean (SD) age was 37 (18), and 86% were male. The mean shock index was 1.1 (0.4) on presentation with a median [IQR] Glasgow Coma Scale of 4 [3-14], and 22.1% had a prehospital cardiac arrest. The study population was profoundly injured with a median injury severity scoreand chest-abbreviated injury scale of 26 [17-38] and 4 [3-5], respectively, with lung (76.5%) being the most injured intrathoracic organs. Overall, the rates of 6-h, 24-h, and in-hospital mortality were 22.5%, 33%, and 53%, respectively, and 51% developed major complications. There was no significant difference in terms of in-hospital mortality (P = 0.800) and major complications (0.416) among pediatrics, adults, and older adults. CONCLUSIONS: One in three patients undergoing TDCS die within the first 24 h, and more than half of them develop major complications and die in the hospital, with no difference among pediatric, adults, and older adults. Future efforts should be directed to improve the survival of these severely injured, metabolically depleted, challenging patients.

SF6 is a useful expander for post-pneumonectomy syndrome in the long-term course: a case report.

BACKGROUND: Post-pneumonectomy syndrome (PPS) is a rare but serious condition that can occur after pneumonectomy. It is characterized by a mediastinal shift towards the vacated hemithorax, which can potentially lead to respiratory failure. The management of PPS poses a clinical challenge, especially in the context of the limited availability of certain therapeutic devices due to regulatory restrictions in Japan. CASE PRESENTATION: A 36-year-old female with stage IB non-small cell lung cancer underwent left pneumonectomy. Approximately 2 years later, she developed dyspnea. After consulting with our hospital, subsequent imaging revealed an extreme mediastinal shift causing bronchial obstruction. Emergency thoracotomy and subsequent sulfur hexafluoride (SF6) injections were successfully used to manage her condition. Over the course of follow-up, the interval between SF6 injections was extended from 3 to 11 months, indicating an improvement in the intrathoracic condition. CONCLUSIONS: This case illustrates the efficacy of SF6 gas in treating PPS and in reducing the frequency of medical interventions. SF6 gas administration is safe and effective for the treatment of patients with PPS.

Chest tube management following two row vertebral body tethering for adolescent idiopathic scoliosis.

BACKGROUND: The current gold standard of scoliosis correction procedures is still posterior spinal fusion, an extensively studied procedure. anterior vertebral body tethering is a newer surgical technique for the correction of scoliotic curves. Consequently, best practices have yet to be determined. METHODS: A single-institution, retrospective, review of all patients diagnosed with adolescent idiopathic scoliosis who underwent two row anterior vertebral body tethering between June 2020 and April 2022 was performed. RESULTS: Over the study period, 95 patients met inclusion: 79 females (83.2%) and 16 males (16.8%), age 14.4 ± 2.5 years, with a body mass index of 20.0 ± 2.9, and an average of 8.4 ± 2.1 levels treated. 28 (29.5%) procedures were for double curves and 67 (70.5%) for single curves. After tethering, a chest tube was positioned in each corrected side. A total of 123 chest tubes were analyzed, including 67 single curves and 28 double curves. The average chest tube duration was 2.5 ± 1.1 days and the average length of stay was 5.0 ± 2.0 days. The average chest tube output eight hours prior to removal was 61.1 ± 45.6 mL. There was no significant difference in average length of stay for patients who underwent correction of a single curve versus a double curve nor was there a difference in average length of stay or chest tube duration for revisions compared to primary procedures. For the entire cohort, the 30-day emergency department visit rate was 7.4% (n = 7) and the readmission rate was 4.2% (n = 4). CONCLUSIONS: This early review of a 2-year two row vertebral body tethering postoperative experience provides a report of a safe and effective approach to chest tube management at a single academic center.

Analysis of bronchiectasis patients who underwent video-assisted thoracoscopic surgery in a tertiary thoracic surgery center: Ten years of experience.

Background: This study aimed to analyze our video-assisted thoracic surgery (VATS) experience in the surgical treatment of bronchiectasis and the reasons limiting VATS application. Methods: Two hundred one patients (106 males, 95 females; mean age: 39.7±14.1 years; range, 12 to 68 years) who underwent surgical treatment for bronchiectasis between January 2012 and October 2021 were included in the retrospective study. Three groups were created based on the surgical technique used: VATS, thoracotomy, and patients who were converted from VATS to thoracotomy. Results: The most significant presenting symptoms were cough (43%) and excessive sputum expectoration (40%). Surgical intervention was applied to the left side of 60% of the patients, and the most common resection performed in all three groups was left lower lobectomy. The rate of conversion from VATS to thoracotomy was 28.8%, and it was found that dense pleural adhesions were the most common reason. Revision surgery was performed on a total of 11 (5.47%) patients. The frequency of revision surgery did not differ significantly among the three groups (p=0.943). The most common postoperative complication was prolonged air leakage. There was no statistically significant difference in postoperative complication rates among the groups (p=0.417). The rate of surgical treatment of bronchiectasis with VATS was observed to have increased from 11.1% to 77.7% in our clinic. Conclusion: In experienced hands, VATS can be safely applied in the surgical treatment of bronchiectasis.

The Hemodynamic Changes Induced by Lung Recruitment Maneuver to Predict Fluid Responsiveness in Children during One Lung Ventilation-A Prospective Observational Study.

BACKGROUND: The prediction of fluid responsiveness in critical patients helps clinicians in decision making to avoid either under- or overloading of fluid. This study was designed to determine whether lung recruitment maneuver (LRM) would have an effect on the predictability of fluid responsiveness by the changes of hemodynamic parameters in pediatric patients who were receiving lung-protective ventilation and one-lung ventilation (OLV). METHODS: A total of 34 children, aged 1-6 years old, scheduled for heart surgeries via right thoracotomy were enrolled. Patients were anesthetized and OLV with lung-protection ventilation settings was established, and then, positioned on left lateral decubitus. LRM and volume expansion (VE) were performed in sequence. Heart rate (HR), systolic arterial pressure (SAP), mean arterial pressure (MAP) diastolic arterial pressure (DAP), stroke volume (SV), stroke volume variation (SVV), and pulse pressure variation (PPV) were recorded via an A-line based monitor system at the following time points: before and after LRM (T1 and T2) and before and after VE (T3 and T4). An increase in stroke volume (SV) or mean arterial pressure (MAP) of ≥10% following fluid loading identified fluid responders. The predictability of fluid responsiveness by the changes of SV (ΔSVLRM) and MAP (ΔMAPLRM) after LRM and VE were statistically evaluated by receiver operating characteristic curves [area under the curves (AUC)]. RESULTS: SVs in all patients were significantly decreased after LRM (p < 0.01) and then, increased and returned to baseline after VE (p < 0.01). In total, 16 out of 34 patients who were fluid responders had significantly lower SV after LRM compared to that in fluid non-responders. The area under the receiver operating characteristic curves for ΔSVLRM was 0.828 (95% confidence interval [CI], 0.660 to 0.935; p < 0.001) and it indicated that ΔSVLRM was able to predict the fluid responsiveness of pediatric patients. MAPs in all patients were also decreased significantly after LRM, and 12 of them fell into the category of fluid responders after VE. Statistically, ΔMAPLRM did not predict fluid responsiveness when LRM was considered as an influential factor (p = 0.07). CONCLUSIONS: ΔSVLRM, but not ΔMAPLRM, showed great reliability in the prediction of the fluid responsiveness following VE in children during one-lung ventilation with lung-protective settings.

Spontaneous Intercostal Artery Bleeding in a Patient With Buerger's Disease: A Case Report.

Intercostal artery (ICA) injury and bleeding are well-known complications of thoracic procedures and trauma; however, spontaneous ICA bleeding is a rare condition usually associated with specific underlying disorders that typically lead to the weakening of vasculature. Herein, we present a 42-year-old male with a history of Buerger's disease who developed spontaneous bleeding of the second left ICA after undergoing lower limb angioplasty. The bleeding was complicated by a large hemothorax and retropleural hematoma, resulting in hemorrhagic shock that necessitated massive transfusion, embolization, and eventual thoracotomy with evacuation.

Comparative outcomes of video-assisted thoracoscopic surgery versus open surgery for bronchogenic cysts in adults: a retrospective cohort study.

Background: Open thoracotomy has been the traditional surgical approach for patients with bronchogenic cysts (BCs). This study aimed to evaluate the safety and efficacy of video-assisted thoracoscopic surgery (VATS) compared to open surgery for the treatment of BCs in adults. Methods: This single-institution, retrospective cohort study included 117 consecutive adult patients who underwent VATS (group A) or open surgery (group B) for BC resection between February 2019 and January 2023. Data regarding clinical history, operation duration, length of hospital stay, 30-day mortality, and recurrence during follow-up were collected and analyzed. Results: Of the total cohort, 103 (88.0%) patients underwent VATS, while 14 (12.0%) patients underwent open surgery. Patients' age in group B were much older than group A (P=0.014), and no significant differences in other demographic and baseline clinical characteristics were observed between the groups. The VATS group had shorter median operation duration (96 vs. 149.5 min, P<0.001) and shorter mean length of hospital stay (5.0±5.5 vs. 8.6±4.0 days, P<0.001). One death occurred in the open surgery group. During a median follow-up of 34 (interquartile range, 20.8-42.5) months, no instances of BC recurrence were observed in either group. Conclusions: Compared to open surgery, VATS is also a safe and efficacious approach for treating BCs in adults. What's more, VATS offered shorter operative times and hospital stays. Considering the minimally invasive, VATS may be a better choice in most patients with bronchial cysts.

The safety and feasibility of mini-invasive Bentall surgery via right anterior mini-thoracotomy.

Background: The right anterior mini-thoracotomy (RAMT) approach has become a popular technique in cardiac surgery and applied in valve surgery. However, there is very limited evidence on the application of RAMT in the Bentall surgery. In the present study, we aimed to evaluate the safety and feasibility of the RAMT approach in Bentall surgery. Methods: A retrospective analysis was performed on 27 patients who underwent Bentall surgery between September 2020 and April 2022 in the First Affiliated Hospital of Xi'an Jiaotong University. Follow-ups were undertaken 1 and 6 months after their operations. The baseline, perioperative, and follow-up results were retrospectively analyzed. Results: A total of 27 male patients aged 48-61 years were included in the study. The operation time ranged from 4.0 to 5.0 hours, with a median of 4.5 hours. The median aortic cross-clamping time was 122 minutes [interquartile range (IQR): 109-145 minutes], and the median cardiopulmonary bypass (CPB) time was 156 minutes (IQR: 143-183 minutes). The median intensive care unit stay was 3 days (IQR: 1.75-4.25 days). The ventilation time ranged from 6.5 to 22.0 hours, with a median of 13.0 hours. The median drainage volume in the first 24 hours was 210 mL. In the following-up data, no deaths or severe complications were observed. Conclusions: The mini-Bentall procedure through an RAMT approach is a feasible and safe approach with few wounds and good clinical results in patients undergoing aortic root replacement.

Post-thoracotomy pain syndrome in the era of minimally invasive thoracic surgery.

Post-thoracotomy pain syndrome (PTPS) is defined as pain around the wound that persists for more than 2 months after surgery. Persistent pain not only increases the use of analgesics and their side effects but also causes many social problems, such as decreased activities of daily living, decreased quality of life, and increased medical costs. In particular, thoracic surgery is associated with a higher frequency and severity of chronic pain than is surgery for other diseases. The basic principles of postoperative pain treatment, not limited to thoracic surgery, are multimodal analgesic methods (using combinations of several drugs to minimize opioid use) and around-the-clock treatment (administering analgesics at a fixed time and in sufficient doses). Thoracic surgeons must always be aware of the following three points: acute severe postoperative pain is a major risk factor for chronic pain; neuropathic pain due to intercostal nerve injury is a major cause of postoperative pain after thoracic surgery, and its presence must not be overlooked from the acute stage; and analgesics must be administered in sufficient quantities according to dosage and volume. The frequency of PTPS has decreased compared with that in the standard thoracotomy era because of the development of analgesia and the widespread use of minimally invasive procedures such as thoracoscopic surgery and robot-assisted surgery. However, no consistently effective prevention or treatment strategies for PTPS have yet been established. In this review, we focus on PTPS in the era of minimally invasive surgery and discuss the role of thoracic surgeons in its management.

Early chest tube removal within 6 hours after thoracic surgery results in improved postoperative prognosis and no adverse effects.

Background: Advances in minimally invasive surgery and drainage systems have caused earlier chest-tube-removal. This retrospective study aimed to assess the safety of early chest tube removal using the institution's new criteria 6 hours after thoracic surgery. Methods: Elective thoracic surgery patients from 2017 to 2023 were reviewed for meeting or not meeting the newer institutional requirement for early chest tube removal; (I) no air leak detected under the digital drainage device observation; (II) no fluid drainage of ≥100 mL/h; (III) no ≥3 combined risks [male, chronic obstructive pulmonary disease (COPD), body mass index (BMI) of <18.5 kg/m2, severe pleural adhesion, upper lobe lobectomy, or left upper division segmentectomy]. The incidence of adverse events, including chest tube replacement, subcutaneous tube placement, and postoperative thoracentesis, were investigated for 1 month postoperatively. Perioperative outcomes and factors involved in conventional chest tube removal were also assessed. Results: Of the 942 patient charts reviewed, 244 (25.9%) met the criteria for chest tube removal within 6 hours postoperatively. This patient group did not experience adverse events. They also demonstrated shorter postoperative hospital stay (4 vs. 6 days, P<0.001), and lesser postoperative complications (7.4% vs. 25.6%, P<0.001) compared to those for whom early chest tube removal was not done. A correlation with thoracotomy, COPD, and steroid and/or immunosuppressant use was observed for patients in the conventional chest tube removal group. Conclusions: Early chest tube removal after 6 postoperative hours was deemed safe for a selected group of patients who met the criteria for early chest tube removal. This study would support the potential expansion of our early removal criteria.

Muscle-sparing Vertical Thoracotomy in Children and Adolescents.

BACKGROUND: Traditional posterolateral thoracotomy (PLT) is a painful and potentially morbid operation associated with an extensive recovery and a long, unsightly scar. In contrast, vertical thoracotomy (VT) is designed to spare muscles, avoid skin flaps, and minimize incision length, thereby limiting postoperative pain, hastening recovery, and improving scar cosmesis. METHODS: We reviewed children aged 1-21 that underwent PLT and VT at our institution from 1/1/2013-12/1/2023. We analyzed demographic data, operative details, and clinical outcomes with special attention paid to total oral morphine equivalents (OME), time to ambulation, and wound complications. RESULTS: We identified 105 patients who underwent PLT and 74 who underwent VT. Both groups were heterogeneous with a greater proportion of oncology patients that received wedge resection in the VT group and congenital lung lesions that received lobectomy in the PLT group. VT patients tended to be older and heavier than PLT patients. Patients who underwent VT demonstrated improved time to ambulation (1.4 ± 0.3 vs 3.0 ± 1.4 days, p = 0.037) and oral morphine equivalent requirements (1.4 ± 0.4mgOME/kg vs 3.5 ± 1.8mgOME/kg, p = 0.035) compared to those who underwent PLT. Additionally, no patients in the VT group required division of the serratus or latissimus, compared to 8 (8%) in the PLT group (p = 0.004). CONCLUSION: Muscle-sparing vertical thoracotomy provides excellent exposure for most intrathoracic pediatric operations, results in a cosmetically acceptable scar that is easily hidden by the upper arm, may reduce the frequency of division of the latissimus and serratus, and does not worsen time to ambulation or post-operative opioid requirements.
