Background: Video-assisted thoracic surgery is currently the recommended treatment for patients with empyema thoracis. However, open-window thoracostomy (OWT) is not uncommon and is performed as a last resort in patients who are in poor general condition or with complicated empyema. Although several professional associations have recommended vacuum-assisted closure (VAC) as an adjunct to standard treatment, exact data regarding the clinical role of intrathoracic VAC are not available. The primary objective of this study was to determine the safety and efficacy of intrathoracic VAC in debilitated patients and to compare the results with those of previous OWT studies., Methods: We investigated 127 patients with a poor performance status who initially received inpatient intrathoracic VAC for stage II/III empyema thoracis between January 2010 and December 2020., Results: The median duration of VAC was 15 days, and the median length of stay was 18 days. Two patients had complications, and the in-hospital mortality rate was 11.8% (15 of 127). Among the 112 surviving patients, 25 (22.3%) were discharged with OWT and 87 (77.7%) were discharged with a closed chest. Empyema recurred in 5 patients. Ultimately, we recorded an absolute success rate of 64.6% (82 of 127)., Conclusions: Intrathoracic VAC appears to be safer and associated with less morbidity and mortality than OWT in debilitated patients with empyema. Our results revealed a reduced hospital length of stay and an improved success rate. The results of this work should contribute to improving treatment success in pleural empyema patients., Competing Interests: Disclosures The authors have no conflicts of interest to disclose., (Copyright © 2024 The Society of Thoracic Surgeons.

Background: Enhanced recovery after surgery (ERAS) is a perioperative care protocol, which was introduced several years ago and has gained increasing importance in thoracic surgery. The aim of this study was to provide guidance through clinical implementation and to identify factors for better compliance., Methods: This prospective cohort study collected data between July 2021 and June 2022 at the Department of Thoracic Surgery (University Hospital Regensburg, Germany). A modified enhanced recovery after thoracic surgery (ERATS) protocol with recommendations covering the pre-, intra- and postoperative phases was established and followed. The primary objective was to evaluate the implementation of the ERATS protocol. Secondary, specific and clinically relevant recommendations were analyzed regarding their compliance., Results: The study included 139 patients undergoing elective lung resections. Many ERATS recommendations were already part of standard perioperative care, including perioperative antibiotics, venous thromboembolism prophylaxis and intraoperative warming. Other measures such as anemia management, carbohydrate loading or chest drain management were updated or newly established and standardized according to our ERATS protocol. The recommendations emphasizing early postoperative mobilization were found to be crucial. We identified three groups with significantly different compliance rates: (I) patient-dependent measures which require active participation (49.3%); (II) treatment measures requiring interdisciplinary consensus (85.8%); and (III) surgical measures (88%)., Conclusions: The implementation and continuous evaluation of our perioperative ERATS protocol led to a new categorization of targeted measures into three groups with actors of different competencies. The new grouping enables gradual implementation and a step-by-step targeted approach in order to achieve a higher compliance of ERATS in the future as well as long-term sustainability., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-23-1866/coif).

Background: Suspicious tumors of the lung require specific staging, intraoperative detection, and histological confirmation. We performed an intrathoracic, intraoperative contrast-enhanced ultrasound (Io-CEUS) for characterization of lung cancer., Methods: Retrospective analysis of prospectively collected data on the application of Io-CEUS in thoracic surgery for patients with operable lung cancer. Analysis of the preoperative chest CT scan and FDG-PET/CT findings regarding criteria of malignancy. Immediately before lung resection, the intrathoracic Io-CEUS was performed with a contrast-enabled T-probe (6-9 MHz-L3-9i-D) on a high-performance ultrasound machine (Loqic E9, GE). In addition to intraoperative B-mode, color-coded Doppler sonography (CCDS), or power Doppler (macrovascularization) of the lung tumor, contrast enhancement (Io-CEUS) was used after venous application of 2.4-5 mL sulfur hexafluoride (SonoVue, Bracco, Italy) for dynamic recording of microvascularization. The primary endpoint was the characterization of operable lung cancer with Io-CEUS. Secondly, the results of Io-CEUS were compared with the preoperative staging., Results: The study included 18 patients with operable lung cancer, who received Io-CEUS during minimally invasive thoracic surgery immediately prior to lung resection. In the chest CT scan, the mean size of the lung tumors was 2.54 cm (extension of 0.7-4.5 cm). The mean SUV in the FDG-PET/CT was 7.6 (1.2-16.9). All lung cancers were detected using B-mode and power Doppler confirmed macrovascularization (100%) of the tumors. In addition, Io-CEUS showed an early wash-in with marginal and mostly simultaneous central contrast enhancement., Conclusions: The intrathoracic application of Io-CEUS demonstrated a peripheral and simultaneous central contrast enhancement in the early phase, which seems to be characteristic of lung cancer. In comparison to preoperative imaging, Io-CEUS was on par with the detection of malignancy and offers an additional tool for the intraoperative assessment of lung cancer before resection.

Malignant pleural effusion is a common diagnosis in metastasized cancers. It is always of palliative character. Main symptoms are dyspnoea and reduced quality of life. Diagnosis is made by ultrasound-guided puncture of the pleural effusion (cytology) and often video-assisted thoracic surgery with biopsy of the pleural surface (histology). The goal of treatment is a fast, sustainable, minimally invasive, patient-centred therapy that increases quality of life. Besides systemic therapy and best supportive care the patient can be treated with local therapy including either pleurodesis (via drainage or VATS) or an indwelling-pleural catheter (IPC). Decision for one of these procedures is made upon performance index (ECOG), expandability of the lung, prognosis and the patient's wish. For the first technique, the lung must be expandable. The latter one (IPC) can be implanted both with expandable and trapped lung. Both are similarly effective in symptom control., Competing Interests: Erklärung zu finanziellen Interessen Forschungsförderung erhalten: nein; Honorar/geldwerten Vorteil für Referententätigkeit erhalten: nein; Bezahlter Berater/interner Schulungsreferent/Gehaltsempfänger: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an im Bereich der Medizin aktiven Firma: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an zu Sponsoren dieser Fortbildung bzw. durch die Fortbildung in ihren Geschäftsinteressen berührten Firma: nein Erklärung zu nichtfinanziellen Interessen Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Cytoreductive surgery (CRS) combined with hyperthermic intrathoracic chemoperfusion (HITOC) is a promising treatment strategy for pleural mesothelioma (PM). The aim of this study was to evaluate the impacts of this multimodal approach in combination with systemic treatment on disease-free survival (DFS) and overall survival (OS). In this retrospective multicenter study, clinical data from patients after CRS and HITOC for PM at four high-volume thoracic surgery departments in Germany were analyzed. A total of 260 patients with MPM (220 epithelioid, 40 non-epithelioid) underwent CRS and HITOC as part of a multimodal treatment approach. HITOC was administered with cisplatin alone (58.5%) or cisplatin and doxorubicin (41.5%). In addition, 52.1% of patients received neoadjuvant and/or adjuvant chemotherapy. The median follow-up was 48 months (IQR = 38 to 58 months). In-hospital mortality was 3.5%. Both the resection status (macroscopic complete vs. incomplete resection) and histologic subtype (epithelioid vs. non-epithelioid) had significant impacts on DFS and OS. In addition, adjuvant chemotherapy (neoadjuvant/adjuvant) significantly increased DFS ( p = 0.003). CRS and HITOC within a multimodal treatment approach had positive impacts on the survival of patients with epithelioid PM after macroscopic complete resection. The addition of chemotherapy significantly prolonged the time to tumor recurrence or progression.

Thoracic surgery in Germany is primarily provided in non-university centres with a clinical focus and less at university hospitals. The extent to which scientific activity can be achieved within these different structures is investigated on the basis of publication output.A PubMed analysis was carried out for selected authors (leader in thoracic surgery in Germany) between Jan 2012 to Dec 2021. University hospitals, DKG-certified lung cancer centres (DKG: German Cancer Society) and DGT-certified thoracic centres (DGT: German Society for Thoracic Surgery) were included.An analysis of n = 54 non-university centres (DKG certificate n = 50 and/or DGT certificate n = 22) and n = 36 university hospitals (n = 9 autonomous clinic/department) was performed. A total of n = 2414 publications were identified, with original papers (n = 1776; 74%) and publications focussing on thoracic surgery (n = 1501; 62%) being found most frequently. The publication performance of the non-university centres was n = 599 publications (11/centre) and thus significantly lower than that of the university hospitals (n = 902; 25/clinic; p ≤ 0.001). Significantly higher publication output was confirmed for autonomous (n = 560; 62/clinic) compared to non-autonomous university thoracic surgery (n = 342; 13/clinic; p = 0.003). A 10-year trend was recorded, with almost doubling of publication output from n = 105 (university: n = 63) to n = 203 (university: n = 124) publications/year. The cumulative impact factors (IF) resulted in 2845 IF (52.7 IF/clinic) for non-university centres, 6361 IF (235.6 IF/clinic) for non-autonomous and 2931 IF (325.7 IF/clinic) for autonomous university thoracic surgery.Scientific activities have increased in non-university centres, but above all in university thoracic surgery. These positive developments are in acute danger due to the upcoming political changes (Hospital Structure Act, minimum volumes). Structural changes such as independent university thoracic surgery or cooperation models with non-university centres could offer solutions., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

In modern perioperative care concepts, multimodal ERAS (Enhanced Recovery After Surgery) is a multimodal perioperative treatment concept for improving postoperative recovery of surgical patients after an operation. This is managed by the so-called ERAS Society and through which hospitals can also be officially certified. The focus of the ERAS concept is on uniform patient care from admission to discharge, with the aim of improving perioperative processes by implementing evidence-based protocols involving a multidisciplinary treatment team. In 2019, ERAS guidelines were published for the first time by the European Society of Thoracic Surgery (ESTS), in cooperation with the ERAS Society, for specific lung resection procedures, and these identified a total of 45 graduated recommendations or Enhanced Recovery Pathways (ERP). The implementation of ERAS concepts in thoracic surgery (ERATS = Enhanced Recovery After Thoracic Surgery) is intended to establish standardised perioperative procedures based on study results and/or expert recommendations. These recommendations take into account organisational aspects as well as thoracic surgical and anaesthesiological procedures, with the overriding goal of creating a structured treatment plan tailored to the patient. All these measures should result in a multimodal overall concept, which should primarily lead to an improved outcome after elective thoracic surgery and secondarily to shorter hospital stays with correspondingly lower costs.This review article describes basic ERAS principles and provides a compact presentation of the most important European ERAS recommendations from the authors' point of view, together with typical obstacles to the implementation of the corresponding ERATS program in German thoracic surgery., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.
