Abstract	(1) Background: Abdominal compartment syndrome (ACS) is a life-threatening situation and is associated with high mortality in the intensive care unit (ICU). Decompressive laparotomy represents the last therapeutic option. This cohort study aims to optimize the selection of ICU patients suffering from ACS who benefit from decompressive laparotomy. (2) Methods: All available data from adult patients treated at the 12 ICUs of a university hospital between 2011 and 2019 were included. Outcome parameters for patients with and without extracorporeal membrane oxygenation (ECMO) were compared. (3) Results: 207 ICU patients with ACS undergoing surgery were identified. Laparotomy resulted in immediate improvement of organ functions in 15% of patients, who then survived more frequently. The overall mortality rate in our cohort was 69%. The group of ECMO patients—including va- and vv-ECMO—showed significantly less organ function improvement and a higher mortality rate of 79% compared to a better postoperative improvement and a lower mortality rate of 62% in non-ECMO patients. (4) Conclusions: There are ICU patients who benefit from decompressive laparotomy—nevertheless, mortality is high. Non-ECMO patients have a better prognosis than ECMO patients. Our findings can support clinical decision-making on emergency surgery and the development of future guidelines.

Abstract	Summary: To investigate underlying mechanisms for cancer metastasis and promising therapies in animal models, spontaneous metastasis models can be used to recreate metastasis development. Here, we present three mouse models of spontaneous lung and/or liver metastasis induction. We describe steps for cancer cell preparation, mouse analgesia, and three injection techniques (subcutaneous, intracecal, and intramucosal). We then detail procedures for evaluating metastasis. Most of these models generate metastasis in a time span of 4 weeks in the majority of injected mice.For complete details on the use and execution of this protocol, please refer to Giannou et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Abstract	Abstract To determine whether a new surgical method using a flexible endoscope (FlexVATS) to perform sparing debridement and apply negative-pressure therapy without extensive decortication may be an alternative treatment option for empyema. Surgical treatment of pleural empyema is associated with considerable postoperative complications and mortality rates, and alternative treatment options are being explored to improve patient outcomes. This was a prospective case series. Seventeen consecutive patients treated with FlexVATS between February 2021 and August 2022 were included in the study. Only patients for whom FlexVATS was the first therapeutic intervention for pleural empyema were included. Treatment success, defined as infection resolution, was the primary endpoint of the study. The secondary endpoints were length of hospital stay, 90-day mortality, and empyema cavity volume reduction. Patients who had previously been treated for pleural empyema by either drainage or surgery were excluded. The trial was performed as a single-centre study at a tertiary medical centre in Germany. In total, 17 patients with pleural empyema were included in the study. The median (IQR) duration of vacuum treatment was 15 days (8–35 days). Twelve of the 17 (71%) patients were successfully treated, and a significant reduction in the empyema cavity volume was observed. 41% of the dressing changes were performed outside the operating room. Compared with a historic cohort of conventionally treated patients (decortication via VATS or thoracotomy), the 90-day mortality rates tended to be lower without reaching statistical significance. Three patients (18%) died in hospital during treatment. No negative pressure-therapy-related complications were observed. FlexVATS therapy is a promising alternative therapy for both healthy and debilitated patients with pleural empyema. Larger randomised trials are required to validate this treatment option.

Abstract	Dickkopf-related protein 1 (DKK1), an antagonist of the canonical Wnt pathway, has received tremendous attention over the past years as its dysregulation is said to be critically involved in a wide variety of gastrointestinal cancers. However, the potential clinical implications of DKK1 remain poorly understood. Although multimodal treatment options have been implemented over the past years, esophageal cancer (EC) patients still suffer from poor five-year overall survival rates ranging from 15% to 25%. Especially prognostic factors and biomarkers for risk stratification are lacking to choose the most beneficial treatment out of the emerging landscape of different treatment options. In this study, we analyzed the serum DKK1 (S-DKK1) levels of 91 EC patients prior to surgery in a single center study at the University Medical Center Hamburg-Eppendorf by enzyme-linked immunosorbent assay. High levels of S-DKK1 could be especially observed in patients suffering from esophageal adenocarcinoma which may promote the hypothesis of a crucial role of DKK1 in inflammation. S-DKK1 levels of ≥5800 pg/mL were shown to be associated with unfavorable five-year survival rates and the presence of CTCs. Interestingly, significantly lower S-DKK1 levels were detected in patients after neoadjuvant treatment, implying that S-DKK1 may serve as a useful biomarker for treatment monitoring. Multivariate analysis identified S-DKK1 as an independent prognostic marker with respect to overall survival in EC patients with a hazard ratio of 2.23. In conclusion, our data implicate a negative prognostic role of DKK1 with respect to the clinical outcome in EC patients. Further prospective studies should be conducted to implement S-DKK1 into the clinical routine for risk stratification and treatment monitoring.

Abstract	Despite continuous improvements in multimodal therapeutic strategies, esophageal carcinoma maintains a high mortality rate. Metastases are a major life-limiting component; however, very little is known about why some tumors have high metastatic potential and others not. In this study, we investigated thermogenic activity and adhesion strength of primary tumor cells and corresponding metastatic cell lines derived from two patients with metastatic adenocarcinoma of the esophagus. We hypothesized that the increased metastatic potential of the metastatic cell lines correlates with higher thermogenic activity and decreased adhesion strength. Our data show that patient-derived metastatic esophageal tumor cells have a higher thermogenic profile as well as a decreased adhesion strength compared to their corresponding primary tumor cells. Using two paired esophageal carcinoma cell lines of primary tumor and lymph nodes makes the data unique. Both higher specific thermogenesis profile and decreased adhesion strength are associated with a higher metastatic potential. They are in congruence with the clinical patient presentation. Understanding these functional, biophysical properties of patient derived esophageal carcinoma cell lines will enable us to gain further insight into the mechanisms of metastatic potential of primary tumors and metastases. Microcalorimetric evaluation will furthermore allow for rapid assessment of new treatment options for primary tumor and metastases aimed at decreasing the metastatic potential.

Abstract	The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is responsible for eliciting Coronavirus disease 2019 (COVID-19) still challenges healthcare services worldwide. While many patients only suffer from mild symptoms, patients with some pre-existing medical conditions are at a higher risk for a detrimental course of disease. However, the underlying mechanisms determining disease course are only partially understood. One key factor influencing disease severity is described to be immune-mediated. In this report, we describe a post-mortem analysis of 45 individuals who died from SARS-CoV-2 infection. We could show that although sociodemographic factors and premedical conditions such as obesity and diabetes mellitus reduced survival time in our cohort, they were not associated with changes in the expression of immune-related signature genes at the RNA level in the blood, the gut, or the liver between these different groups. Our data indicate that obesity and diabetes mellitus influence SARS-CoV-2-related mortality, without influencing the extrapulmonary gene expression of immunity-related signature genes at the RNA level.

Abstract	Summary: The transplantation model provides the opportunity to assess the relevance of a molecule of interest for tumor cell extravasation by using a respective genetically modified donor animal. Here, we present a protocol for orthotopic single-lung transplantation in mice as a tool for lung metastasis studies. We describe steps for animal preparation, lung transplantation, and tumor cell injection. We then detail procedures for the direct comparison of tumor cell spreading between the genetically modified left lung and the naive right lung parenchyma.For complete details on the use and execution of this protocol, please refer to Giannou et al. (2023).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Abstract	Background Concomitant liver cirrhosis is a crucial risk factor for major surgeries. However, only few data are available concerning cirrhotic patients requiring esophagectomy for malignant disease. Methods From a prospectively maintained database of esophageal cancer patients, who underwent curative esophagectomy between 01/2012 and 01/2016, patients with concomitant liver cirrhosis (liver-cirrhotic patients, LCP) were compared to non-liver-cirrhotic patients (NLCP). Results Of 170 patients, 14 cirrhotic patients with predominately low MELD scores (≤ 9, 64.3%) were identified. Perioperative outcome was significantly worse for LCP, as proofed by 30-day (57.1% vs. 7.7, p<0.001) and 90-day mortality (64.3% vs. 9.6%, p<0.001), anastomotic leakage rate (64.3 vs. 22.3%, p = 0.002) and sepsis (57.1 vs. 21.5%, p = 0.006). Even after adjustment for age, gender, comorbidities, and surgical approach, LCP revealed higher odds for 30-day and 90-day mortality compared to NLCP. Moreover, 5-year survival analysis showed a significantly poorer long-term outcome of LCP (p = 0.023). For risk stratification, none of the common cirrhosis scores proved prognostic impact, whereas components as Bilirubin (auROC 94.4%), INR (auROC = 90.0%), and preoperative ascites (p = 0.038) correlated significantly with the perioperative outcome. Conclusion Curative esophagectomy for cirrhotic patients is associated with a dismal prognosis and should be evaluated critically. While MELD and Child score failed to predict perioperative mortality, Bilirubin and INR proofed excellent prognostic capacity in this cohort.
