Perioperative and mid-term outcomes of robotic-assisted versus video-assisted minimally invasive esophagectomy for esophageal cancer: a retrospective propensity-matched analysis of 842 patients.

Comparing the safety, effectiveness, and mid-term survival rates of robot-assisted minimally invasive esophagectomy (RAMIE) and video-assisted minimally invasive esophagectomy (VAMIE). A total of 842 patients undergoing minimally invasive esophagectomy were analyzed, including 694 patients in VAMIE group and 148 in RAMIE group. PSM analysis was applied to generate matched pairs for further comparison. Operative outcomes, postoperative complications and Mid-term outcomes were compared between all patients in matched groups. After 1:4 PSM, 148 patients in the RAMIE and 592 patients in the VAMIE. Compared to VAMIE, RAMIE exhibited earlier removal of chest and neck drainage tubes, shorter postoperative hospital stays, and a higher number of lymph node dissections. However, the surgical duration of RAMIE was longer than that of VAMIE. Postoperative complications were no statistically significant between the RAMIE and VAMIE groups. There was no statistically significant difference in the 3-year OS and DFS between the two groups. Compared to VAMIE, RAMIE emerges as a viable and safe surgical approach and suggests RAMIE as a potential alternative to minimally invasive esophagectomy.

Pulmonary tuberculosis and secondary spontaneous tension pneumothorax in HIV patient: case report

Tuberculosis remains as one of the top 10 infectious diseases causing mortality worldwide. In year 2022, Tuberculosis has caused an estimated 1.30 million deaths with 1.13 million of death caused by tuberculosis alone, while 167000 cases in TB-HIV coinfection. Secondary Spontaneous Pneumothorax has been well known as a complication of Tuberculosis, although the incidence is quite rare, it could be life threatening especially if the pneumothorax progress to tension pneumothorax. Patient, male 19 years old came to the emergency room with a sudden shortness of breath for 3 hours prior to hospital admission. X-ray thorax examination showed collapse of the right lung with hyperlucent avascular findings on the right lung, which suggest secondary spontaneous tension pneumothorax. He was treated with chest tube insertion and WSD placement, 2 hours after WSD placement, he became pulseless. ACLS protocols were given and unfortunately, we were unable to achieve ROSC on him. Tuberculosis remains one of the deadliest infection diseases, but can still be treated with the DOTS regimen. Some condition can make tuberculosis difficult to treat, such as immunodeficiency patient like HIV/AIDS. Spontaneous Pneumothorax has been well known as a complication of tuberculosis, although the incidence rate of pneumothorax in tuberculosis are quite low, however it could be life-threatening if it develops into a tension pneumothorax, especially in the settings of advanced stage HIV patients. Spontaneous pneumothorax can be fatal especially when it develops to tension pneumothorax. Further research is needed to know what population who are at risk of developing pneumothorax.

Application of tissue pneumoperitoneum technique around lymph nodes in thoracoscopic lung cancer resection.

Thoracoscopic surgery is a primary treatment for lung cancer, with lobectomy and mediastinal lymph node dissection being the predominant surgical approaches for invasive lung cancer. While many thoracic surgeons can proficiently perform lobectomy, thorough and standardized lymph node dissection remains challenging. This study aimed to explore a safer and more efficient surgical method for mediastinal lymph node dissection in lung cancer. A prospective randomized controlled study was conducted, involving 100 patients with right lung cancer who were admitted to our hospital from January 2021 to April 2024 and met the inclusion criteria. These patients were randomly divided into an observation group (tissue pneumoperitoneum technique around lymph nodes group) and a control group (conventional surgery group). Thoracoscopic lobectomy and mediastinal lymph node dissection were performed. Intraoperative and postoperative related indicators were observed to validate the effectiveness and safety of the tissue pneumoperitoneum technique around lymph nodes. The observation group showed a significantly shorter lymph node dissection surgery time compared to the control group, with a statistically significant difference (p < 0.05). The number of lymph nodes dissected in the observation group was significantly higher than that in the control group, with a statistically significant difference (p < 0.05). Although the observation group had slightly more mediastinal lymph node stations dissected than the control group, the difference was not statistically significant (p > 0.05). The total drainage volume within three days postoperatively was comparable between the two groups, with no statistically significant difference (p > 0.05). The observation group had shorter chest tube indwelling time and postoperative hospital stay than the control group, with statistically significant differences (p < 0.05). The incidence of surgical complications was similar between the two groups, and there were no perioperative deaths. The tissue pneumoperitoneum technique around lymph nodes is a more efficient method for mediastinal lymph node dissection in lung cancer, demonstrating safety and feasibility, and is worthy of promotion.

Parasternal thoracotomy via sternocostal disarticulation: a novel surgical approach to the canine thorax.

To describe the technique and outcomes of a modified paramedian thoracic approach in dogs involving a parasternal thoracotomy via rib disarticulation at the sternocostal joint. 93 client-owned dogs. Medical records of dogs that underwent parasternal thoracotomy at a private practice between the years 2015 and 2021 were reviewed. Signalment, weight, clinical presentation, surgical details, complications, and short-term outcomes were recorded. Cox proportional hazards regression models were utilized to analyze the impact of covariates on hazard events. Kaplan-Meier curves were employed to evaluate survival functions for select variables. Parasternal thoracotomy via sternocostal disarticulation was performed in 93 dogs. Eighty-eight dogs (94.6%) survived the procedure. Eighty-three dogs (89.2%) survived to discharge from the hospital. Age, weight, postoperative time to eating, postoperative ambulation, and surgical or anesthetic duration were not significantly associated with survival to discharge. Thoracostomy tube duration significantly decreased the likelihood for survival to discharge; for each additional hour of thoracostomy tube placement, the odds of survival to discharge diminished by 5.7% (hazard ratio, 0.94; 95% CI, 0.912 to 0.976). Parasternal thoracotomy via rib disarticulation at the sternocostal joints may be a viable alternative to median sternotomy that does not require specialized equipment for bilateral hemithoracic visualization. Postoperative complications and short-term outcomes are comparable to those reported for the traditional median sternotomy approach. Prolonged thoracostomy tube duration may impact survival to discharge.

Inpatient Complication Rates of Bronchoscopic Lung Volume Reduction in the United States

Early randomized controlled trials (RCTs) of bronchoscopic lung volume reduction (BLVR) have shown clinically meaningful benefits in lung function, dyspnea, and quality of life in patients with severe emphysema. Safety outcome data following BLVR in the US are scarce outside the RCTs. What is the rate of inpatient complications after BLVR in the real world in the US? We used The National In-patient Sample (NIS) database to identify in-hospital complications post-BLVR from 2018 to 2020. Complications were defined as pneumothorax, COPD exacerbation, pneumonia, hemoptysis, acute respiratory failure, and valve removal. We also analyzed all-cause in-hospital mortality and length of stay (LOS). We identified 467 admissions related to BLVR procedures. The number of procedures doubled between 2019 and 2020 (from 153 to 295 procedures). The median age was 67.9 years (IQR 61.1 - 72.8), 210 (45.0%) were female, 401 (85.8%) were white, and Medicare was the primary expected payer in 72.8% of cases. Most procedures were done in urban teaching hospitals (56.9%). The rate of pneumothorax was 26.3%, acute respiratory failure 19.5%, COPD exacerbation 8.8%, pneumonia 7.3%, and hemoptysis 5.3%. Chest tube placement was required in 84 out of 123 (68.3%) cases of pneumothorax. The endobronchial valve had to be removed in 69 cases (14.8%). The median LOS was 2.8 days (IQR 2.3 -4.5). The number of in-hospital deaths was less than 11 cases (< 2.3%). Overall, the subgroup who had in-hospital complications did not differ significantly from the others in terms comorbidities, demographics, and hospital characteristics. The real-world complication rate after BLVR was similar to the published complication rates from early randomized clinical trials. In-hospital mortality was low, suggesting that aside from the commonly anticipated complications, BLVR is a safe treatment option for severe emphysema.

Impact of radiomics features, pulmonary emphysema score and muscle mass on the rate of pneumothorax and chest tube insertion in CT-guided lung biopsies

Iatrogenic pneumothorax is a relevant complication of computed tomography (CT)-guided percutaneous lung biopsy. The aim of the present study was to analyze the prognostic significance of texture analysis, emphysema score and muscle mass derived from CT-imaging to predict postinterventional pneumothorax after CT-guided lung biopsy. Consecutive patients undergoing CT-guided percutaneous lung biopsy between 2012 and 2021 were analyzed. Multivariate logistic regression analysis included clinical risk factors and CT-imaging features to detect associations with pneumothorax development. Overall, 479 patients (178 females, mean age 65 ± 11.7 years) underwent CT-guided percutaneous lung biopsy of which 180 patients (37.5%) developed pneumothorax including 55 patients (11.5%) requiring chest tube placement. Risk factors associated with pneumothorax were chronic-obstructive pulmonary disease (COPD) (p = 0.03), age (p = 0.02), total lung capacity (p < 0.01) and residual volume (p = 0.01) as well as interventional parameters needle length inside the lung (p < 0.001), target lesion attached to pleura (p = 0.04), and intervention duration (p < 0.001). The combined model demonstrated a prediction accuracy of the occurrence of pneumothorax with an AUC of 0.78 [95%CI: 0.70–0.86] with a resulting sensitivity 0.80 and a specificity of 0.66. In conclusion, radiomics features of the target lesion and the lung lobe CT-emphysema score are predictive for the occurrence of pneumothorax and need for chest insertion after CT-guided lung biopsy.

Approach to primary spontaneous pneumothorax: Experiences of a new pediatric surgery clinic

BackgroundThe prevalence of spontaneous pneumothorax in children during adolescence is low, but not negligible. Treatment involves conservative management and surgery. The aim of this study was to review our patients treated with diagnoses of primary spontaneous pneumothorax and to describe our therapeutic approach, outcomes, and deficiencies. MethodsNinety (90) patients diagnosed with primary spontaneous pneumothorax and treated and followed-up in our clinic between June 2020 and December 2023 were included in the study. The research was performed as a retrospective file review. Trauma, secondary pneumothorax, and newborn pneumothorax were excluded. ResultsSeventy six (76) patients were boys and 14 were girls, with a mean age of 16,23 years. Right pneumothorax was present in 44 patients, left pneumothorax in 41, and bilateral pneumothorax in 5. The 90 patients’ initial treatment involved tube thoracostomy, and 36 individuals with prolonged and recurrent pneumothorax underwent video-assisted thoracoscopic surgery (VATS). ConclusionThe success rate of apical wedge resection and mechanical pleurodesis with direct VATS in the treatment of prolonged and recurrent primary spontaneous pneumothorax in children is greater than 90 %. We think that, VATS is a successful, effective and safe treatment for spontaneous pneumothorax due to a significantly lower recurrence rate compared to chest tube insertion.

Fully Dual-Portal Robotic-Assisted Thoracic Surgery (F-DRATS) and Indocyanine Green-Navigated Segmentectomy

Background: In the landscape of thoracic surgery, innovation continually drives progress, offering novel approaches to address complex pathologies while prioritizing patient well-being. Dual-port robotic-assisted thoracic surgery (DRATS) represents a new frontier in this evolution. In this report, we describe our experience with the fully dual-port robotic-assisted thoracic surgery (F-DRATS) approach for segmentectomy with the indocyanine green intersegmental plane identification. Methods: We define as F-DRATS the robotic thoracic surgery performed by two intercostal incisions without rib spreading, using the robotic camera, robotic dissecting instruments, and exclusively robotic staplers. We herein describe our F-DRATS approach in lingulectomy and lymphadenectomy of stations 5, 6, 7, and 10 using the da Vinci Surgical System. Results: The patient’s postoperative course was uneventful with the chest tube removed on the second postoperative day. The final pathological analysis confirmed a low-grade malignant potential adenocarcinoma, with a main diameter of 1.1 cm, at 3 cm from the lung margins. Conclusions: This is the first description in the literature of a F-DRATS lingulectomy with ICG intersegmental plane identification.

Subxiphoid Single-Port Robotic Thymectomy Using the Single-Port Robotic System versus VATS: A Multi-Institutional, Retrospective, and Propensity Score-Matched Study.

Subxiphoid thymectomy is a novel alternative to the transthoracic approach and sternotomy, with potential benefits, such as reduced postoperative pain and faster recovery. We previously reported the initial experience with subxiphoid single-port robotic-assisted thoracic surgery (SRATS) thymectomy using the single-port robotic system (SPS). However, the efficacy of this technique remains unknown. Thus, this study examined the multi-institutional experience with SRATS thymectomy and compared the perioperative outcomes of this technique to those of subxiphoid single-port video-assisted thoracic surgery (SVATS) thymectomy. The data of patients who underwent subxiphoid SRATS and SVATS thymectomy, performed by three thoracic surgeons at three institutions between September 2018 and May 2024, were retrospectively collected. In total, 110 patients were included, with 85 and 25 undergoing SRATS and SVATS thymectomy, respectively. After propensity score matching, 25 patients were included in each group. The SRATS group was associated with a lower conversion rate to multi-port surgery (0% vs. 20%, p = 0.05), shorter chest tube drainage duration (1.32 ± 0.75 vs. 2.00 ± 1.29 days, p = 0.003), and a shorter postoperative hospital stay (2.52 ± 1.00 vs. 5.08 ± 5.20 days, p = 0.003). Subxiphoid SRATS thymectomy using the SPS is feasible and is a good alternative to conventional thymectomy. Further studies are necessary to confirm its benefits.

Do all traumatic hemothorax require a tube thoracostomy: A retrospective review

Abstract Background: Blunt thoracic trauma accounts for a majority of trauma-related admissions. The Eastern Association for the Surgery of Trauma guidelines recommend placement of a tube thoracostomy for all patients with a hemothorax. Our study was conducted to look at those managed without an intercostal drain (ICD) and the factors that could predict a failure in conservative management. Materials and Methods: A retrospective study was conducted from January 2020 to June 2022 at a level-one trauma center in South India to account for patients who required a tube thoracostomy after planned expectant management for hemothorax. All adult patients above 16 years, with traumatic hemothorax were included. Those who had ICD inserted in the emergency department before computed tomography (CT) and those who did not have a CT Thorax were excluded. A retrospective review of patient records was conducted and analyzed using Stata (ver. 16). Results: Eighty-eight patients were included in the study, of whom 11 patients required a tube thoracostomy after an initial trial of conservative/expectant management (i.e., not inserting an ICD). The most common reason for failure was an increase in the size of the hemothorax. Among all the predictors we looked at, only a systolic blood pressure of &lt;90 mm Hg on presentation was statistically significant for predicting failure of expectant management. Conclusion: Our study suggests not all patients with a traumatic hemothorax require a tube thoracostomy and can be managed expectantly provided close monitoring is possible. An increase in the size of the hemothorax was the main indication for a tube thoracostomy.

Intrapleural Fibrinolytic Interventions for Retained Hemothoraces in Rabbits.

Bleeding within the pleural space may result in persistent clot formation called retained hemothorax (RH). RH is prone to organization, which compromises effective drainage, leading to lung restriction and dyspnea. Intrapleural fibrinolytic therapy is used to clear the persistent organizing clot in lieu of surgery, but fibrinolysin selection, delivery strategies, and dosing have yet to be identified. We used a recently established rabbit model of RH to test whether intrapleural delivery of single-chain urokinase (scuPA) can most effectively clear RH. scuPA, or single-chain tissue plasminogen activator (sctPA), was delivered via thoracostomy tube on day 7 as either one or two doses 8 h apart. Pleural clot dissolution was assessed using transthoracic ultrasonography, chest computed tomography, two-dimensional and clot displacement measurements, and gross analysis. Two doses of scuPA (1 mg/kg) were more effective than a bolus dose of 2 mg/kg in resolving RH and facilitating drainage of pleural fluids (PF). Red blood cell counts in the PF of scuPA, or sctPA-treated rabbits were comparable, and no gross intrapleural hemorrhage was observed. Both fibrinolysins were equally effective in clearing clots and promoting pleural drainage. Biomarkers of inflammation and organization were likewise comparable in PF from both groups. The findings suggest that single-agent therapy may be effective in clearing RH; however, the clinical advantage of intrapleural scuPA remains to be established by future clinical trials.

Pericardiocentesis, Chest Tube Insertion, and Needle Thoracostomy During Resuscitation of Nontraumatic Adult In-Hospital Cardiac Arrest: A Retrospective Cohort Study.

In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the postresuscitation period, and we do not know current post-IHCA practice patterns. To address this gap, we developed the Discover IHCA study, which will thoroughly evaluate current post-IHCA care practices across a diverse cohort. Our study collects granular data on post-IHCA treatment practices, focusing on temperature control and prognostication, with the objective of describing variation in current post-IHCA practices. This is a multicenter, prospectively collected, observational cohort study of patients who have suffered IHCA and have been successfully resuscitated (achieved ROSC). There are 24 enrolling hospital systems (23 in the United States) with 69 individuals enrolling in hospitals (39 in the United States). We developed a standardized data dictionary, and data collection began in October 2023, with a projected 1000 total enrollments. Discover IHCA is endorsed by the Society of Critical Care Medicine. The study collects data on patient characteristics, including prearrest frailty, arrest characteristics, and detailed information on postarrest practices and outcomes. Data collection on post-IHCA practice was structured around current American Heart Association and European Resuscitation Council guidelines. Among other data elements, the study captures postarrest temperature control interventions and postarrest prognostication methods. The majority of participating hospital systems are large, academic, tertiary care centers serving urban populations. The analysis will evaluate variations in practice and their association with mortality and neurologic function. We expect this study, Discover IHCA, to identify variability in practice and outcomes following IHCA and be a vital resource for future investigations into best practices for managing patients after IHCA.

Comparison of the Clinical Effects of Two Chest Drainage Devices for Thoracoscopic Lung Surgeries

Comparison of the Clinical Effects of Two Chest Drainage Devices for Thoracoscopic Lung Surgeries

Reduced Incidence of Pneumothorax and Chest Tube Placement following Transthoracic CT-Guided Lung Biopsy with Gelatin Sponge Torpedo Track Embolization: A Propensity Score-Matched Study.

Objectives: To evaluate the effectiveness of track embolization using gelatin sponge torpedo in reducing the incidence of pneumothorax and chest tube placement after percutaneous CT-guided lung biopsy. Methods: A retrospective single-center analysis of percutaneous computed tomography (CT)-guided transthoracic lung biopsies was performed between 2017 and 2022. After excluding the patients who received an ultrasound-guided biopsy, combined lung biopsy with ablation, fiducial placement, unsuccessful procedure due to uncooperative patient, and age under 18 years, 884 patients' clinical information was collected (667 without track embolization and 217 with track embolization). The incidence of early and late pneumothorax and chest tube placement were compared between the two groups. Propensity score matching (PSM) was applied to minimize selection bias. Univariable and multivariable analyses were performed to determine risk factors for pneumothorax. Results: After PSM, the baseline differences and all factors that could affect the incidence of pneumothorax were balanced between the track embolization group (217 patients) and the non-track embolization group (217 patients). The incidence rates of early pneumothorax (13.4% vs. 24.0% p = 0.005), late pneumothorax (11.0% vs. 18.0% p = 0.021), and chest tube placement (0.9% vs. 4.6% p = 0.036) were significantly decreased in the track embolization group. However, the success rate of tissue diagnosis yield and length of hospital stay were not significantly different between the two groups. In multivariate analysis, the risk of pneumothorax increased as the fissure was passed (OR = 3.719, p = 0.027). Conclusions: Using track embolization with a gelatin sponge torpedo significantly decreased the incidence of pneumothorax and chest tube placement following percutaneous CT-guided lung biopsy.

Epidemiology and Management of Pediatric Group A Streptococcal Pneumonia With Parapneumonic Effusion: An Observational Study.

During autumn/winter 2022, UK pediatricians reported an unseasonal increase in invasive group A streptococcal infections; a striking proportion presenting with pneumonia with parapneumonic effusion. Clinicians across the United Kingdom were requested to submit pseudonymized clinical data using a standardized report form for children (<16 years) admitted between September 30, 2022 and February 17, 2023, with microbiologically confirmed group A streptococcal pneumonia with parapneumonic effusion. From 185 cases submitted, the median patient age was 4.4 years, and 163 (88.1%) were previously healthy. Respiratory viral coinfection was detected on admission for 101/153 (66.0%) children using extended respiratory pathogen polymerase chain reaction panel. Molecular testing was the primary method of detecting group A streptococcus on pleural fluid (86/171; 50.3% samples). Primary surgical management was undertaken in 171 (92.4%) children; 153/171 (89.4%) had pleural drain inserted (96 with fibrinolytic agent), 14/171 (8.2%) had video-assisted thoracoscopic surgery. Fever duration after admission was prolonged (median, 12 days; interquartile range, 9-16). Intravenous antibiotic courses varied in length (median, 14 days; interquartile range, 12-21), with many children receiving multiple broad-spectrum antibiotics, although evidence for additional bacterial infection was limited. Most cases occurred with viral coinfection, a previously well-recognized risk with influenza and varicella zoster, highlighting the need to ensure routine vaccination coverage and progress on vaccines for other common viruses (eg, respiratory syncytial virus, human metapneumovirus) and for group A streptococcus. Molecular testing is valuable to detect viral coinfection and confirm invasive group A streptococcal diagnosis, expediting the incorporation of cases into national reporting systems. Range and duration of intravenous antibiotics administered demonstrated the need for research on the optimal duration of antimicrobials and improved stewardship.

A Clinical Study on the Treatment of Adult Atrial Septal Defect Using Thoracoscopic-Assisted Right Vertical Infra-Axillary Thoracotomy, Total Thoracoscopic, and Median Sternotomy Approaches

Background: To compare the clinical outcomes of three surgical approaches for treating adult atrial septal defects (ASD): Thoracoscopic-assisted right vertical infra-axillary thoracotomy (TARVIAT) under central cardiopulmonary bypass (CPB), totally thoracoscopic (TT), and median sternotomy (MS) approaches, and to assess the feasibility and safety of the TARIAVT approach. Methods: This study reviewed 62 cases patients of repairing atrial septal defects via a TARVIAT and central extracorporeal circulation from 2019 to 2023. The patients included 22 males, aged between 18 and 59 years, with a mean age of 33.35 ± 10.97 years. The surgical indications were adult patients with moderate to severe tricuspid regurgitation and who were unsuitable for interventional closure of atrial septal defects. Exclusion criteria included patients diagnosed with severe pulmonary hypertension or Eisenmenger syndrome. Additionally, 67 patients who underwent TT approach repair of ASD and 72 patients who underwent MS approach repair of ASD were selected as the control groups. Operative time, CPB time, aortic clamping time, postoperative Intensive care unit (ICU) stay, postoperative mechanical ventilation time, 24-hour postoperative chest drainage, incision length, postoperative hospital stay, hospital costs, and postoperative complications were compared to assess statistical differences. Results: There were no deaths or major complications observed in any of the three groups. Statistically significant differences were found among the three groups in terms of extracorporeal circulation time, aortic clamping time, surgical time, 24-hour postoperative chest drainage, postoperative mechanical ventilation time, postoperative ICU stay, incision length, and postoperative hospital stay (p &lt; 0.05). The TT group exhibited longer CPB and aortic clamping times compared to the TARVIAT and MS groups, while demonstrating lower 24-hour postoperative chest drainage volumes compared to the TARIAVT and MS groups. Both the TARVIAT and TT groups showed shorter surgical times, postoperative mechanical ventilation times, postoperative ICU stay, incision lengths, and postoperative hospital. However, there were no statistically significant differences among the three groups regarding hospital costs, postoperative left ventricular ejection fraction (LVEF) values, and the incidence of postoperative complications (p &gt; 0.05). Conclusions: TARVIAT under central CPB is feasible and safe for adult patients. This approach presents lower invasiveness, shorter operative duration, and faster recovery compared to other methods. In conclusion, the TARVIAT approach for repairing adult ASD is both safe and effective, offering a viable surgical option for this condition.

Spontaneous hemopneumothorax causing life-threatening hemorrhage: a case report

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

In ILD, a step-up diagnostic strategy vs. immediate surgical biopsy reduced need for unexpected chest tube drainage.

Impact of the interval between neoadjuvant immunotherapy and surgery on prognosis in esophageal squamous cell carcinoma (ESCC): a real-world study

BackgroundThe time interval between neoadjuvant immunotherapy and surgery is 6 weeks for esophageal squamous cell carcinoma (ESCC), but whether delayed surgery affects prognosis remains unclear.MethodsClinical data of locally advanced ESCC who underwent neoadjuvant immunotherapy followed by esophagectomy from November 2019 to December 2022 were collected. The surgery outcomes and prognosis were compared between short-interval (time to surgery ≤ 6 weeks) and long-interval groups (time to surgery > 6 weeks).Results152 patients were enrolled totally, with a ratio of 91:61 between short-interval and long-interval groups. The rate of pathological complete response in the short-interval and long-interval groups were 34.1% and 24.6% (P = 0.257). Delayed surgery did not have a significantly impact on the number of lymph node dissections (P = 0.133), operative duration (P = 0.689), blood loss (P = 0.837), hospitalization duration (P = 0.293), chest drainage duration (P = 0.886) and postoperative complications (P > 0.050). The 3-year Overall survival (OS) rates were 85.10% in the short-interval group, and 82.07% in the long-interval group (P = 0.435). The 3-year disease-free survival (DFS) rates were 83.41% and 70.86% in the two groups (P = 0.037). Subgroup analysis revealed that patients with a favorable response to immunotherapy (tumor regression grade 0) exhibited inferior 3-year OS (long-interval vs. short-interval: 51.85% vs. 91.08%, P = 0.035) and DFS (long-interval vs. short-interval: 47.40% vs. 91.08%, P = 0.014) in the long-interval group.ConclusionsDelayed surgery after neoadjuvant immunotherapy does not further improve pathological response; instead, it resulted in a poorer DFS. Especially for patients with a favorable response to immunotherapy, delayed surgery increases the risk of mortality and recurrence.

The analgesic effects of combined bilateral parasternal block and serratus anterior plane block for coronary artery bypass grafting surgery

BackgroundSevere pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB).MethodsEthics committee approval (E.Kurul-E2-24-6176, 07/02/2024) was received for the study. Then, the trial was registered on www.clinicaltrials.gov (https://clinicaltrials.gov/) under the identifier NCT05427955 on 17/03/2024. Twenty patients between the ages of 18–80, with ASA physical status classification II-III, undergoing coronary artery bypass grafting CABG with sternotomy, were included. While the patients were under general anesthesia, PSB was performed through the second and fourth intercostal spaces, and SAPB was performed over the sixth rib. The primary outcome was VAS (Visual Analog Scale) during the first 12 h after extubation. The secondary outcomes were intraoperative remifentanil consumption and block-related side effects.ResultsThe average age of the patients was 64 years. Five patients were female, and 15 were male. For the sternum area, only one patient had resting VAS scores of 4, while the VAS scores for resting for the other patients were below 4. For chest tubes area, only two patients had resting VAS scores of 4 or above, while the resting VAS scores for the other patients were below 4. The patients’ intraoperative remifentanil consumption averaged 2.05 mg. No side effects related to analgesic protocol were observed in any of the patients.ConclusionsIn this preliminary study where PSB and SAPB were combined in patients undergoing CABG, effective analgesia was achieved for the sternum and chest tubes area.
