Background: In-hospital mortality of septic critically ill patients with COVID-19 is significantly higher than in those without COVID-19. The knowledge on long-term outcomes remains scarce. In this retrospective analysis, we compare clinical characteristics, long-term functional outcomes, and survival in septic critically ill patients with and without COVID-19., Methods: Data of septic critically ill patients without COVID-19 were collected as part of the Comprehensive Sepsis Center Dresden-Kreischa registry from 2020 to 2023. The data of septic critically ill patients with COVID-19 were collected as part of the local ARDS/COVID-19 registry over the same period. Diagnosis of sepsis was based on the Sepsis-3 definition. Variables collected for analyses were obtained from electronic health records. Long-term follow-up was performed 6-12 months after sepsis diagnosis. Survival was depicted using Kaplan-Meier curves. Associations between long-term mortality and risk factors were modeled by Cox Regression., Results: 372 septic patients without COVID-19 and 301 with COVID-19 were enrolled. Septic patients with COVID-19 were significantly younger, had a significantly lower Charlson Comorbidity Index, and had a significantly higher SOFA score at ICU admission. Long-term follow-up showed a significantly higher mortality in septic patients with COVID-19 (73.4 % vs. 30.1 %; HR 3.4 (95 % CI 2.73-4.27; p < 0.05)). COVID-19 infection was associated with significant increased mortality (adjusted HR 3.27; 95 % CI 2.48-4.33; p < 0.05) and reduced health-related quality of life, measured by the EQ-5D-3 L Index, (0.56 (0.16-0.79) vs. 0.79 (0.69-0.99); p < 0.05)., Conclusions: In our cohort of septic critically ill patients, health-related quality of life and long-term survival were considerably reduced in patients with concomitant COVID-19. Furthermore, COVID-19 could be identified as an independent risk factor for higher long-term mortality in these patients., Competing Interests: Declaration of competing interest None of the authors has a conflict of interest to declare., (Copyright © 2024.

Purpose: In patients with traumatic, infectious, degenerative, and neoplastic surgical indications in the cervical spine, commonly the anterior approach is used. Often these patients require a tracheostomy necessary due to prolonged mechanical ventilation. The limited spinal mobility and proximity to the surgical site of anterior cervical spine fixation (ACSF) could pose an increased risk for complications of percutaneous dilational tracheostomy (PDT.) Importantly, PDT might raise wound infection rates of the cervical spine approach. The aim of this study is to prove safety of PDT after ACSF., Methods: We performed a retrospective, single-center study comparing patients with and without ACSF who underwent Ciaglia-single step PDT. After propensity score matching using logistic regression, we compared intra- and postprocedural complication rates. Furthermore, surgical site infections were evaluated. Putensen's definitions of complications and Clavien-Dindo's classification were used., Results: A total of 1175 patients underwent PDT between 2009 and 2021. Fifty-seven patients underwent PDT following ACSF and were matched to fifty-seven patients without ACSF. The mean interval between ACSF and PDT was 11.3 days. The overall complication rate was 19.3% in the ACSF group and 21.1% in the non-ACSF group. The mean follow-up was 388 days (± 791) in the ACSF group and 424 days (± 819) in the non-ACSF group. Life-threatening complications (Clavien-Dindo IV to V) were found in 1.8% of ACSF patients and 3.5% of non-ACSF patients. There were no significant differences in complication rates. No surgical site infection of the anterior spine access was detected., Conclusion: PDT is a feasible and safe procedure in patients after ACSF. Complication rates are comparable to patients without ACSF. Surgical site infections of ACSF are very rare., (© 2024. The Author(s).)

Background: The COVID-19 pandemic revealed a need for better collaboration among research, care, and management in Germany as well as globally. Initially, there was a high demand for broad data collection across Germany, but as the pandemic evolved, localized data became increasingly necessary. Customized dashboards and tools were rapidly developed to provide timely and accurate information. In Saxony, the DISPENSE project was created to predict short-term hospital bed capacity demands, and while it was successful, continuous adjustments and the initial monolithic system architecture of the application made it difficult to customize and scale., Methods: To analyze the current state of the DISPENSE tool, we conducted an in-depth analysis of the data processing steps and identified data flows underlying users' metrics and dashboards. We also conducted a workshop to understand the different views and constraints of specific user groups, and brought together and clustered the information according to content-related service areas to determine functionality-related service groups. Based on this analysis, we developed a concept for the system architecture, modularized the main services by assigning specialized applications and integrated them into the existing system, allowing for self-service reporting and evaluation of the expert groups' needs., Results: We analyzed the applications' dataflow and identified specific user groups. The functionalities of the monolithic application were divided into specific service groups for data processing, data storage, predictions, content visualization, and user management. After composition and implementation, we evaluated the new system architecture against the initial requirements by enabling self-service reporting to the users., Discussion: By modularizing the monolithic application and creating a more flexible system, the challenges of rapidly changing requirements, growing need for information, and high administrative efforts were addressed., Conclusion: We demonstrated an improved adaptation towards the needs of various user groups, increased efficiency, and reduced burden on administrators, while also enabling self-service functionalities and specialization of single applications on individual service groups., Competing Interests: Outside the scope of this study, Jochen Schmitt has received consultation fees from Novartis, Lilly, and Sanofi, and his institution has been granted funding for investigator-initiated research from Novartis, Sanofi, Pfizer, and ALK.

Introduction: Since the beginning of the pandemic in spring 2020, inpatient healthcare has been under enormous burden, which is reflected especially in overworked staff, imprecise bed planning and/or data transfer. According to the recommendation of the Science Council, university clinics should play a controlling role in regional healthcare and act in conjunction with surrounding hospitals and practices., Methods: In September 2021, 31 representatives from 18 university hospitals were invited to a hybrid Delphi study with a total of 4 survey rounds to discuss criteria for effective inpatient care in a pandemic situation, which were extracted from previous expert interviews. Criteria that were classified as very important/relevant by≥75% of the participants in the first round of the survey (consensus definition) were then further summarized in 4 different small groups. In a third Delphi round, all participants came together again to discuss the results of the small group discussions. Subsequently, these were prioritized as Optional ("can"), Desirable ("should") or Necessary ("must") recommendations., Results: Of the invited clinical experts, 21 (67.7%) participated in at least one Delphi round. In an online survey (1st Delphi round), 233 criteria were agreed upon and reduced to 84 criteria for future pandemic management in four thematic small group discussions (2nd Delphi round) and divided into the small groups as follows: "Crisis Management and Crisis Plans" (n=20), "Human Resources Management and Internal Communication" (n=16), "Regional Integration and External Communication" (n=24) and "Capacity Management and Case & Care" (n=24). In the following group discussion (3rd Delphi round), the criteria were further modified and agreed upon by the experts, so that in the end result, there were 23 essential requirements and recommendations for effective inpatient care in a pandemic situation., Conclusion: The results draw attention to key demands of clinical representatives, for example, comprehensive digitization, standardization of processes and better (supra) regional networking in order to be able to guarantee needs-based care even under pandemic conditions. The present consensus recommendations can serve as guidelines for future pandemic management in the inpatient care sector., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Introduction: Early detection of severe complications may reduce morbidity and mortality in patients undergoing hepatic resection. Therefore, we prospectively evaluated a panel of inflammatory blood markers for their value in predicting postoperative complications in patients undergoing liver surgery., Methods: A total of 139 patients undergoing liver resections (45 wedge resections, 49 minor resections, and 45 major resections) were prospectively enrolled between August 2017 and December 2018. Leukocytes, CRP, neutrophil-lymphocyte ratio (NLR), thrombocyte-lymphocyte ratio (TLR), bilirubin, INR, and interleukin-6 and -8 (IL-6 and IL-8) were measured in blood drawn preoperatively and on postoperative days 1, 4, and 7. IL-6 and IL-8 were measured using standardized immunoassays approved for in vitro diagnostic use in Germany. ROC curve analysis was used to determine predictive values for the occurrence of severe postoperative complications (CDC ≥ 3)., Results: For wedge and minor resections, leukocyte counts at day 7 (AUC 0.80 and 0.82, respectively), IL-6 at day 7 (AUC 0.74 and 0.73, respectively), and CRP change (∆CRP) at day 7 (AUC 0.72 and 0.71, respectively) were significant predictors of severe postoperative complications. IL-8 failed in patients undergoing wedge resections, but was a significant predictor of severe complications after minor resections on day 7 (AUC 0.79), had the best predictive value in all patients on days 1, 4, and 7 (AUC 0.72, 0.72, and 0.80, respectively), and was the only marker with a significant predictive value in patients undergoing major liver resections (AUC on day 1: 0.70, day 4: 0.86, and day 7: 0.92). No other marker, especially not CRP, was predictive of severe complications after major liver surgery., Conclusion: IL-8 is superior to CRP in predicting severe complications in patients undergoing major hepatic resection and should be evaluated as a biomarker for patients undergoing major liver surgery. This is the first paper demonstrating a feasible implementation of IL-8 analysis in a clinical setting., (© 2023. The Author(s).)

Secondary transports of patients from one hospital to another are indicated for medical reasons or to address local constraints in capacity. In particular, interhospital transports of critically ill infectious patients present a logistical challenge and can be key in the effective management of pandemic situations. The state of Saxony in Germany has two characteristics that allow for an extensive evaluation of secondary transports in the pandemic year 2020/2021. First, all secondary transports are centrally coordinated by a single institution. Second, Saxony had the highest SARS-CoV-2 infection rates and the highest COVID-19 associated mortality in Germany. This study evaluates secondary interhospital transports from March 2019 to February 2021 in Saxony with a detailed analysis of transport behaviour during the pandemic phase March 2020 to February 2021. Our analysis includes secondary transports of SARS-CoV-2 patients and compares them to secondary transports of non-infectious patients. In addition, our data show differences in demographics, SARS-CoV-2- incidences, ICU occupancy of COVID-19 patients, and COVID-19 associated mortality in all three regional health clusters in Saxony. In total, 12,282 secondary transports were analysed between March 1st, 2020 and February 28th, 2021, of which 632 were associated with SARS-CoV-2 (5.1%) The total number of secondary transports changed slightly during the study period March 2020 to February 2021. Transport capacities for non-infectious patients were reduced due to in-hospital and out-of-hospital measures and could be used for transport of SARS-CoV-2 patients. Infectious transfers lasted longer despite shorter distance, occurred more frequently on weekends and transported patients were older. Primary transport vehicles were emergency ambulances, transport ambulances and intensive care transport vehicles. Data analysis based on hospital structures showed that secondary transports in correlation to weekly case numbers depend on the hospital type. Maximum care hospitals and specialized hospitals show a maximum of infectious transports approximately 4 weeks after the highest incidences. In contrast, standard care hospitals transfer their patients at the time of highest SARS-CoV-2 case numbers. Two incidence peaks were accompanied by two peaks of increased secondary transport. Our findings show that interhospital transfers of SARS-CoV-2 and non-SARS-CoV-2 patients differ and that different hospital care levels initiated secondary transports at different times during the pandemic., (© 2023.

Introduction: Fibrin stabilizing factor (FXIII) plays a crucial role in blood clotting, tissue repair, and immune defense. FXIII deficiency after trauma can lead to prolonged wound healing due to persistent infections or coagulation disorders. The aim of this study was to describe the prevalence of acquired FXIII deficiency after trauma and to provide a description of the time-course changes of important coagulation parameters in relation to FXIII activity. In this context, patient characteristics, laboratory data, and treatment modalities were examined with respect to their influence on FXIII activity. Furthermore, the effects of in vitro administration of FXIII on clot firmness and outcomes in patients with severe traumatic brain injury were investigated., Patients and Methods: Two trauma cohorts (A and B) were examined prospectively in a two-center study, and another (cohort C) was examined retrospectively. In cohort A (trauma patients, n=880) routine laboratory tests were conducted, and FXIII activity was measured. In cohort B (polytrauma patients, n=26), additional clinical parameters were collected, and in-vitro FXIII administration and rotational thromboelastometry (ROTEM) analyses were performed. In cohort C (polytrauma patients with severe traumatic brain injury [sTBI], n=84), the impact of initially measured FXIII activity on clinical outcomes after sTBI was investigated using the modified Rankin Scale (mRS) at least 6 months after trauma., Results: The prevalence of FXIII activity <70% in cohort A was 12.4%, with significant differences in age, Hb, fibrinogen, and Hct levels, platelet count, aPTT, and INR (vs. prevalence of FXIII activity >70%). Cohort B showed a decrease in FXIII activity from 85% to 58% after 7 days. FXIII deficiency correlated with time after trauma, aPTT, and fibrinogen level, lactate, and Hb levels. In-vitro administration of FXIII showed a positive influence on clot firmness due to improved maximum clot firmness (MCF in FIBTEM) and reduced maximum lysis (ML in EXTEM). Finally, a significant difference in FXIII activity between patients after sTBI with good and poor clinical outcomes was observed 6 months after trauma., Conclusion: We demonstrated that trauma-associated FXIII deficiency is a common coagulation disorder, with FXIII deficiency increasing further in the first 7 days after trauma, the period of early surgical care. In vitro administration of FXIII was able to demonstrate significant clot stabilizing effects. For trauma patients with sTBI, FXIII activity could serve as a prognostic parameter, as it differed significantly between patients with good and poor clinical outcomes., Competing Interests: Declaration of Competing Interest The Center for Musculoskeletal Surgery (CMSC) Charité - University Medicine Berlin, Germany was provided with TEG machines, TEG reagent and fibrogramin for in-vitro FXIII assays by CSL Behring Germany for the cohort B studies (cohort A/C no support). Christian Kleber has received honoraria from CSL Behring, Germany, which also supported the funding of the open access publication. The remaining authors have disclosed that they do not have any conflicts of interest., (Copyright © 2022 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Background: In the course of building extension works at Dresden University Hospital, it was necessary to shut down the central medical gas supply in a building with 3 intensive care wards with 22 beds, an operating theater tract with 5 operating rooms and 6 normal wards each with 28 beds during ongoing services. Thus, for the construction phase there was a need to establish an interim decentralized gas supply with zero failure tolerance for the affected functional units ., Methods: Following established procedures for possible risk and failure analysis, a project group was set up by the hospital's emergency and disaster management officer to develop a project plan, a needs assessment and a communication plan., Results: A variety of risk factors were systematically identified for which appropriate countermeasures needed to be designed. The needs assessment over 4 h based on physiological parameters for the maximum available 22 ventilator beds resulted in 26,000 l of oxygen and 26,000 l of compressed air. A total of 7 supply points were each equipped with two 50l cylinders for both oxygen and compressed air, with a total availability of 175,000 l of each of the 2 gases. Another eight cylinders each were held in reserve. The project was carried out on a Saturday without an elective surgery program, so that the operating rooms concerned could be closed. The timing was chosen so that double staffing of intensive care personnel was available during the afternoon shift change. In advance, as many of the patients on mechanical ventilation as possible were transferred within the hospital; however, nine of the mechanically ventilated patients had to remain. The technical intervention in the gas supply lasted only 2 h without affecting the patient's condition. During the 2‑h interim supply, 16,500 l of compressed air and 8000 l of oxygen were consumed on the high-care wards. The calculated hourly consumption per ventilated patient was 917 l of air (15 l/min) and 444 l of oxygen (7 l/min). The quantity framework based on empirical values from intensive care medicine was significantly lower. This was more than compensated for by the 10-fold stocking of gas and the predictably lower number of ventilated patients than the maximum occupancy used as a basis., Conclusion: For technical interventions in high-risk areas, careful planning and execution in an effective team is required. Established procedures of project management and risk assessment help to avoid errors., (© 2023. The Author(s).)

Background: The aim of this study was to assess the usefulness of adding thoracic CT to abdominal CT in intensive care unit (ICU) patients with signs of infection after abdominopelvic surgery., Methods: 143 thoracoabdominal CTs of ICU patients with signs of infection after abdominopelvic surgery were retrospectively reviewed for thoracic pathologies. It was determined if pathologic findings were visible only on thoracic CT above the diaphragmatic dome or also on abdominal CT up to the diaphragmatic dome. All thoracic pathologies visible only above the diaphragmatic dome were retrospectively analyzed by an ICU physician in terms of clinical relevance. Diagnostic and therapeutic efficacy of thoracic CT were assessed with regard to an infectious focus and to other pathologic findings., Results: 297 pathologic thoracic findings were recorded. 26 of the 297 findings could only be detected on images obtained above the diaphragmatic dome (in 23 of 143 CTs). A change in patient management was initiated due to only one of the 26 supradiaphragmatic findings. Diagnostic efficacy of thoracic CT in addition to abdominal CT to identify an infectious focus was 3.5% (95%-CI: 0.5-6.5%) and therapeutic efficacy was 0.7% (95%-CI: 0-2.1%). With regard to all pathologic thoracic findings, diagnostic efficacy was 16.1% (95%-CI: 10.1-22.1%) and therapeutic efficacy remained at 0.7%., Conclusions: Additional thoracic CT to detect an infectious focus in ICU patients after abdominopelvic surgery leads to identification of the focus in only 3.5% and to changes in patient management in only 0.7%. Other relevant findings are more common (16.1%), but very rarely affect patient management., (© 2023. The Author(s).)

Background: In reconstructive surgery, loss of a microvascular free flap due to perfusion disorders, especially thrombosis, is a serious complication. In recent years, viscoelastic testing (VET) has become increasingly important in point-of-care (POC) anticoagulation monitoring. This paper describes a protocol for enhanced anticoagulation monitoring during maxillofacial flap surgery., Objective: The aim of the study will be to evaluate, in a controlled setting, the predictive value of POC devices for the type of flap perfusion disorders due to thrombosis or bleeding. VET, Platelet monitoring (PM) and standard laboratory tests (SLT) are comparatively examined., Methods/design: This study is an investigator-initiated prospective trial in 100 patients undergoing maxillofacial surgery. Patients who undergo reconstructive surgery using microvascular-free flaps will be consecutively enrolled in the study. All patients provide blood samples for VET, PM and SLT at defined time points. The primary outcome is defined as free flap loss during the hospital stay. Statistical analyses will be performed using t-tests, including the Bonferroni adjustment for multiple comparisons., Discussion: This study will help clarify whether VET can improve individualized patient care in reconstruction surgery. A better understanding of coagulation in relation to flap perfusion disorders may allow real-time adaption of antithrombotic strategies and potentially prevent flap complications.

Background: The aim of this study was to describe and compare clinical characteristics and outcomes in critically ill septic patients with and without COVID-19., Methods: From February 2020 to March 2021, patients from surgical and medical ICUs at the University Hospital Dresden were screened for sepsis. Patient characteristics and outcomes were assessed descriptively. Patient survival was analyzed using the Kaplan-Meier estimator. Associations between in-hospital mortality and risk factors were modeled using robust Poisson regression, which facilitates derivation of adjusted relative risks., Results: In 177 ICU patients treated for sepsis, COVID-19 was diagnosed and compared to 191 septic ICU patients without COVID-19. Age and sex did not differ significantly between sepsis patients with and without COVID-19, but SOFA score at ICU admission was significantly higher in septic COVID-19 patients. In-hospital mortality was significantly higher in COVID-19 patients with 59% compared to 29% in Non-COVID patients. Statistical analysis resulted in an adjusted relative risk for in-hospital mortality of 1.74 (95%-CI=1.35-2-24) in the presence of COVID-19 compared to other septic patients. Age, procalcitonin maximum value over 2 ng/ml, need for renal replacement therapy, need for invasive ventilation and septic shock were identified as additional risk factors for in-hospital mortality., Conclusion: COVID-19 was identified as independent risk factor for higher in-hospital mortality in sepsis patients. The need for invasive ventilation and renal replacement therapy as well as the presence of septic shock and higher PCT should be considered to identify high-risk patients., Competing Interests: Declaration of Competing Interest None of the authors has a conflict of interest to declare.

As of late 2019, the COVID-19 pandemic has been a challenge to health care systems worldwide. Rapidly rising local COVID-19 incidence rates, result in demand for high hospital and intensive care bed capacities on short notice. A detailed up-to-date regional surveillance of the dynamics of the pandemic, precise prediction of required inpatient capacities of care as well as a centralized coordination of the distribution of regional patient fluxes is needed to ensure optimal patient care. In March 2020, the German federal state of Saxony established three COVID-19 coordination centers located at each of its maximum care hospitals, namely the University Hospitals Dresden and Leipzig and the hospital Chemnitz. Each center has coordinated inpatient care facilities for the three regions East, Northwest and Southwest Saxony with 36, 18 and 29 hospital sites, respectively. Fed by daily data flows from local public health authorities capturing the dynamics of the pandemic as well as daily reports on regional inpatient care capacities, we established the information and prognosis tool DISPENSE. It provides a regional overview of the current pandemic situation combined with daily prognoses for up to seven days as well as outlooks for up to 14 days of bed requirements. The prognosis precision varies from 21% and 38% to 12% and 15% relative errors in normal ward and ICU bed demand, respectively, depending on the considered time period. The deployment of DISPENSE has had a major positive impact to stay alert for the second wave of the COVID-19 pandemic and to allocate resources as needed. The application of a mathematical model to forecast required bed capacities enabled concerted actions for patient allocation and strategic planning. The ad-hoc implementation of these tools substantiates the need of a detailed data basis that enables appropriate responses, both on regional scales in terms of clinic resource planning and on larger scales concerning political reactions to pandemic situations., Competing Interests: Unrelated to this study, Jochen Schmitt received payments for consultations by Novartis, Lilly and Sanofi, and institutional grands for investigator-initiated research from Novartis, Sanofi, Pfizer, and ALK.

Introduction: The complex and dynamic situation in the current pandemic requires a regionally coordinated and interconnected cooperation between the different stakeholders within the health care system, such as the inpatient sector or the public health service. The aim of this study is to analyze health care management during the COVID-19 pandemic in 2020 with a focus on regional networking and communication structures., Methods: As part of the BMBF-funded project "egePan Unimed", an online questionnaire on pandemic management was sent to the boards of all 35 German university hospitals in November 2020. The questionnaire focused on the core topics of regional networking, crisis management, data exchange, and communication with political stakeholders. The questionnaire consisted of 37 closed and three open-ended questions. After piloting, the invitation to the survey was extended three times by mail and once by telephone., Results: The results (n=25, response 71.4%) show that 68% of the clinics surveyed were connected to representatives from the inpatient sector and 86% to representatives from the public health service. Networking with representatives from the outpatient sector was less common (26%). Of the university hospitals surveyed, 84% had a leadership role in a regional COVID-19 pandemic management effort. Data exchange with regional hospitals in the course of pandemic management took place at 75% of the participating university hospitals and with supra-regional hospitals at 67% of the clinics surveyed., Conclusion: To manage regional medical care during the COVID-19 pandemic in 2020, university hospitals often assumed a coordinating role in the complex pandemic care process. There were often structured collaborations with regional clinics and health departments and comparatively few cooperations with the outpatient care sector. However, this cooperation has the potential to prevent overcrowding in hospitals., (Copyright © 2021. Published by Elsevier GmbH.)

Background & Aims: Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can rapidly progress into acute respiratory distress syndrome accompanied by multi-organ failure requiring invasive mechanical ventilation and critical care treatment. Nutritional therapy is a fundamental pillar in the management of hospitalized patients. It is broadly acknowledged that overfeeding and underfeeding of intensive care unit (ICU) patients are associated with increased morbidity and mortality. This study aimed to assess the energy demands of long-term ventilated COVID-19 patients using indirect calorimetry and to evaluate the applicability of established predictive equations to estimate their energy expenditure., Methods: We performed a retrospective, single-center study in 26 mechanically ventilated COVID-19 patients with resolved SARS-CoV-2 infection in three independent intensive care units. Resting energy expenditure (REE) was evaluated by repetitive indirect calorimetry (IC) measurements. Simultaneously the performance of 12 predictive equations was examined. Patient's clinical data were retrieved from electronic medical charts. Bland-Altman plots were used to assess agreement between measured and calculated REE., Results: Mean mREE was 1687 kcal/day and 20.0 kcal relative to actual body weight (ABW) per day (kcal/kg/day). Longitudinal mean mREE did not change significantly over time, although mREE values had a high dispersion (SD of mREE ±487). Obese individuals were found to have significantly increased mREE, but lower energy expenditure relative to their body mass. Calculated REE showed poor agreement with mREE ranging from 33 to 54%., Conclusion: Resolution of SARS-CoV-2 infection confirmed by negative PCR leads to stabilization of energy demands at an average 20 kcal/kg in ventilated critically ill patients. Due to high variations in mREE and low agreement with calculated energy expenditure IC remains the gold standard for the guidance of nutritional therapy., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest.

Purpose: Postpancreatectomy hemorrhage (PPH) is one of the leading causes of mortality after pancreatic resection. Late onset PPH is most often treated using a transarterial approach. The aim of this study was to analyze risk factors for in-hospital mortality after endovascular treatment., Methods: Between 2012 and 2017, patients who were treated endovascular due to PPH were identified from a retrospective analysis of a database. Risk factors for mortality were identified by univariate analysis., Results: In total, 52 of the 622 patients (8.4%) underwent endovascular treatment due to PPH. The primary technical success achieved was 90.4%. In 59.6% of patients, bleeding control was achieved by placing a stent graft and in 40.4% by coil embolization. The primary 30-day and 1-year patency of the placed covered stents was 89.3% and 71.4%, respectively. The 60-day mortality was 34.6%. The reintervention rate was higher after stent graft placement compared to coiling (39.3% vs. 21.1%, P = 0.012). In the univariate analysis the need for reintervention was associated with a higher in-hospital mortality (21.2% vs. 7.7%, P = 0.049). The use of an antiplatelet agent was associated with a decreased in-hospital mortality in the univariate (11.5% vs. 25%, P = 0.024) and multivariate analysis (HR 3.1, 95% CI 1.1-9, P = 0.034), but did not increase the risk of rebleeding., Conclusion: Endovascular management of delayed PPH has a high technical success rate. Stent graft placement showed a higher reintervention rate. The need for reintervention was associated with a higher in-hospital mortality but did not differ between coiling and stent graft placement.

Purpose: To investigate the outcome of local intra-arterial papaverine infusion therapy in patients with non-occlusive mesenteric ischemia (NOMI), and factors influencing survival, in comparison with a conservative approach., Methods: From 2013 to 2019, patients with NOMI confirmed by imaging were included in a retrospective two-center study. According to different in-house standard procedures, patients were treated in each center either conservatively or interventionally by a standardized local infusion of intra-arterial papaverine into the splanchnic arteries. Thirty-day mortality and factors influencing the outcome, such as different demographics and laboratories, were compared between groups using Kaplan-Meier survival analysis and Cox regression, respectively., Results: A total of 66 patients with NOMI were included, with n = 35 treated interventionally (21 males, mean age 67.7 ± 12.3 years) and n = 31 treated conservatively (18 females, mean age 71.6 ± 9.6 years). There was a significant difference in 30-day mortality between the interventional (65.7%; 12/35 survived) and the conservative group (96.8%; 1/31 survived) (hazard ratio 2.44; P = 0.005). Thresholds associated with a worse outcome of interventional therapy are > 7.68 mmol/l for lactate, < 7.31 for pH and <  - 4.55 for base excess., Conclusion: Local intra-arterial papaverine infusion therapy in patients with NOMI significantly increases survival rate in comparison with conservative treatment. High lactate levels, low pH and high base excess, and high demand for catecholamines are associated with a poor outcome., Level of Evidence: Level III.

Background: Necrotizing pancreatitis is a life-threatening presentation of acute pancreatitis. The mortality of 20-80% initially depends on the persistence of organ failure and systemic inflammatory response syndrome (SIRS) and, in the later course of the disease, on secondary infection of the necrosis. The questions whether prophylactic antibiotics aiming to prevent this infection should be administered and which antibiotic is the best to use, as well as the problem of fungal infection under antibiotic treatment are still intriguing and insufficiently solved., Methods: A search of the literature using PubMed was carried out, supplemented by a review of the programmes of the Digestive Disease Week (DDW) and the United European Gastroenterology Week (UEGW)., Results: Despite the widely practised prophylactic antibiotic administration in severe pancreatitis, no evidence for the benefit of this strategy exists. One of the drawbacks might be a tendency for disastrous fungal infection under prophylactic antibiotics. Bacterial translocation from the gut in the second week after the onset of symptoms is the major source for infection of pancreatic necrosis and provides a clear indication for antibiotic treatment. However, routine fine-needle aspiration for a calculated antibiotic therapy cannot be recommended, and all other tests offer only indirect signs. Important factors such as enteral versus parenteral feeding and the method of necrosectomy are mostly neglected in the trials but seem to be essential for the outcome of the patient., Conclusions: Even though most meta-analyses including the newer double-blind, placebo-controlled trials on prophylactic antibiotics showed no beneficial effects in the prevention of infection of necrosis and/or outcome of the patients, this strategy is still widely used in clinical routine. Since nearly all trials published so far show systematic problems (i.e. inaccurate definition of the severity of the disease, poor statistical testing, and neglect of differences in the route of nutrition), there is a need for randomized controlled prospective trials with exact definitions of the disease.

Aim: The study was designed to determine the suitability of a single-layer continuous anastomosis for ileo-colonic anastomoses and to determine perioperative risk factors for morbidity and mortality in a teaching hospital., Patients and Methods: Perioperative data of 463 patients undergoing colonic surgery with an ileocolonic anastomosis between 2000 and 2007 were retrospectively reviewed. Outcomes were compared using univariate and multivariate analyses to identify risk factors for morbidity, including anastomotic leakage, and mortality., Results: The overall anastomotic leakage rate was 2.1%. In more than 50% right hemicolectomies were performed for colonic cancer. Univariate analysis showed a significant association of the underlying diagnosis with the leakage rate (ischemia 3.0% vs. carcinoma 1.3%). Multivariate analysis identified age, ASA score, diagnosis, and urgency as risk factors for morbidity; and an urgent operation setting (vital indications), a body mass index >25, diabetes mellitus, and a hypotensive circulation upon admission as predictors of anastomotic leakage. The mortality rate was 20% (2/10) among patients with anastomotic leakage and 2.9% (13/453) in those without anastomotic leakage., Conclusion: Single-layer continuous anastomoses for ileo-colonic surgery can be safely performed, even in a teaching setting. Four preoperative risk factors for morbidity and four different factors for anastomotic leakage could be identified in multivariate analysis. If feasible, these factors should have an impact on the preoperative decision-making progress.
