Background Acute pancreatitis (AP) represents a common gastrointestinal disorder. Complicated disease courses in particular still represent a major clinical challenge and are associated with high mortality. Evaluation of existing data sets and their careful interpretation can support a rational discussion to optimize outcomes of this common gastrointestinal disease. Methods We used standardized hospital discharge data provided by the Federal Statistical Office of Germany to evaluate hospital mortality and current developments of AP in Germany between 2008 and 2017. Results In this analysis, 516,618 hospitalized AP cases were included. Main disease etiologies featured biliary (29.9%) and alcoholic (22.7%) AP. The annual frequency of AP increased from 48,858 (2008) to 52,611 (2017), mainly due to a rising incidence of biliary AP. Average hospital mortality was 2.85% and significantly improved over time. While uncomplicated AP had low hospital mortality (1.38%), the presence of organ complications was associated with a mortality of 12.34%. The necessity of mechanical ventilation dramatically increased hospital mortality to 44.06%. Hospital mortality was significantly higher in female patients (3.31%) than males (2.55%) and showed a stepwise increase with patient age. We further identified type 2 diabetes mellitus and obesity as factors associated with increased hospital mortality. Hospital mortality was lowest among patients treated at departments specializing in gastroenterology. Finally, high case volume centers (defined as >98 annual AP cases) had the lowest hospital mortality for patients with complicated courses of AP. Conclusion With over 50,000 annual hospitalization cases, AP is one of the most important inpatient treatment indications in gastroenterology in Germany. Overall, AP mortality has improved in recent years, presumably due to improved interdisciplinary treatment concepts. In this study, we identified important clinical and epidemiological risk factors for an unfavorable course, which could help to improve risk prediction and triaging, and thus the management of AP.
(1) Background: Transarterial chemoembolization (TACE) is a minimally invasive procedure, characterized by the selective occlusion of tumor-feeding hepatic arteries, via injection of an embolizing agent and an anticancer drug. It represents a standard of care for intermediate-stage hepatocellular carcinoma (HCC), and it is also increasingly performed in cholangiocarcinoma (CCA), as well as in liver metastases. Apart from the original method, based on intra-arterial infusion of a liquid drug followed by embolization, newer particle-based TACE procedures have been introduced recently. As yet, comprehensive data on current trends of TACE, as well as its in-hospital mortality in Germany, which could help to further improve outcome following TACE, are missing. (2) Methods: Based on standardized hospital discharge data, provided by the German Federal Statistical Office from 2010 to 2019, we aimed at systematically evaluating current clinical developments and in-hospital mortality related to TACE in Germany. (3) Results: A total of 49,595 individual cases undergoing TACE were identified within the observation period. The overall in-hospital mortality was 1.00% and significantly higher in females compared to males (1.12 vs. 0.93%; p < 0.001). We identified several post-interventional complications, such as liver failure (51.49%), sepsis (33.87%), renal failure (23.9%), and liver abscess (15.87%), which were associated with a significantly increased in-hospital mortality. Moreover, in-hospital mortality significantly differed between the underlying indications for TACE (HCC: 0.83%, liver metastases: 1.22%, and CCA: 1.40%), as well as between different embolization agents (liquid embolization: 0.80%, loaded microspheres: 0.92%, spherical particles: 1.54%, and non-spherical particles: 2.84%), for which we observed large geographic differences in their frequency of use. Finally, in-hospital mortality was significantly increased in centers with a low annual TACE case volume (<15 TACE/year: 2.08% vs. >275 TACE/year: 0.45%). (4) Conclusion: Our data provide a systematic overview of indications and embolization methods for TACE in Germany. We identified a variety of factors, such as post-interventional complications, the embolization method used, and the hospitals’ annual case volume, which are associated with an increased in-hospital mortality following TACE. These data might help to further reduce the mortality of this routinely performed local-ablative procedure in the future.
A unique partial anomalous pulmonary venous return in combination with other rare malformations such as annular pancreas and a persistent umbilical vein was discovered in a female Caucasian cadaver during an anatomical dissection at the Paracelsus Medical University in Nuremberg, Germany. The pulmonary anomaly comprised of the aberrant left superior pulmonary vein connecting the superior lobe of the left lung with the left brachiocephalic vein resulting in a left to right shunt. An annular pancreas without any signs of probable symptom causing duodenal compression was additionally found. To complete the constellation of malformations, a persistent umbilical vein connecting to the inferior branch of the extrahepatic left portal vein running in the round ligament fissure of the liver was also observed. This rare constellation of malformations has been illustrated and thoroughly discussed with the currently available literature to develop a hypothesis for the genetic and developmental background.
Background: Cholangiocarcinoma (CCA) is a rare malignant disease of the biliary tract with an increasing incidence and a high mortality worldwide. Systematic data on epidemiological trends, treatment strategies, and in-hospital mortality of CCA in Germany are largely missing. However, the evaluation and careful interpretation of these data could help to further improve the treatment strategies and outcome of CCA patients in the future. Methods: Standardized hospital discharge data from the German Federal Statistical Office were used to evaluate epidemiological and clinical trends as well as the in-hospital mortality of CCA in Germany between 2010 and 2019. Results: A total of 154,515 hospitalized CCA cases were included into the analyses. The number of cases significantly increased over time (p < 0.001), with intrahepatic CCA (62.5%) being the most prevalent tumor localization. Overall, in-hospital mortality was 11.4% and remained unchanged over time. In-hospital mortality was significantly associated with patients’ age and tumor localization. The presence of clinical complications such as (sub)acute liver failure, acute respiratory distress syndrome (ARDS), or acute renal failure significantly increased in-hospital mortality up to 77.6%. In-hospital mortality was significantly lower among patients treated at high annual case volume centers. Finally, treatment strategies for CCA significantly changed over time and showed decisive differences with respect to the hospitals’ annual case volume. Conclusions: Our data provide a systematic overview on hospitalized CCA patients in Germany. We identified relevant clinical and epidemiological risk factors associated with an increased in-hospital mortality that could help to further improve framework conditions for the management of CCA patients in the future.
Background Selective Internal Radiotherapy (SIRT) is a minimal invasive tumor therapy for hepatocellular carcinoma (HCC), biliary tract cancer (BTC), and liver metastasis of extrahepatic tumors. Comprehensive data on past and current trends of SIRT as well as outcome parameters such as in-hospital mortality and adverse events in Germany are missing. Methods We evaluated current clinical developments and outcomes of SIRT in Germany based on standardized hospital discharge data, provided by the German Federal Statistical Office from 2012 to 2019. Results A total of 11,014 SIRT procedures were included in the analysis. Reflecting the current guideline, the most common indication was hepatic metastases (54.3%; HCC: 39.7%; BTC: 6%) with a trend in favor of HCC and BTC over time. Most SIRTs were performed with yttrium-90 (99.6%) but the proportion of holmium-166 SIRTs increased in recent years. Mean length of hospital stay for ⁹⁰Y based SIRTs was 3.67 ± 2 days and for 166Ho based SIRTs 2.9 ± 1.3 days. Overall in-hospital mortality was 0.14%. The mean number of SIRTs/hospital was 22.9 (SD ± 30.4). The 20 highest case volume centers performed 25.6% of all SIRTs. Conclusion Our study gives a detailed insight into indications, patient-related factors, and the incidence of adverse events as well as the overall in-hospital mortality in a large SIRT collective in Germany. SIRT is a safe procedure with low overall in-hospital mortality and a well-definable spectrum of adverse events. We report differences in the regional distribution of performed SIRTs and changes in the indications and used radiopharmaceuticals over the years.
Background Liver failure (LF) is characterised by a loss of the synthetic and metabolic liver function and is associated with a high mortality. Large-scale data on recent developments and hospital mortality of LF in Germany are missing. A systematic analysis and careful interpretation of these datasets could help to optimise outcomes of LF. Methods We used standardised hospital discharge data of the Federal Statistical Office to evaluate current trends, hospital mortality and factors associated with an unfavourable course of LF in Germany between 2010 and 2019. Results A total of 62,717 hospitalised LF cases were identified. Annual LF frequency decreased from 6716 (2010) to 5855 (2019) cases and was higher among males (60.51%). Hospital mortality was 38.08% and significantly declined over the observation period. Mortality significantly correlated with patients’ age and was highest among individuals with (sub)acute LF (47.5%). Multivariate regression analyses revealed pulmonary (ORARDS: 2.76, ORmechanical ventilation: 6.46) and renal complications (ORacute kidney failure: 2.04, ORhepatorenal syndrome: 2.92) and sepsis (OR: 1.92) as factors for increased mortality. Liver transplantation reduced mortality in patients with (sub)acute LF. Hospital mortality significantly decreased with the annual LF case volume and ranged from 47.46% to 29.87% in low- or high-case-volume hospitals, respectively. Conclusions Although incidence rates and hospital mortality of LF in Germany have constantly decreased, hospital mortality has remained at a very high level. We identified a number of variables associated with increased mortality that could help to improve framework conditions for the treatment of LF in the future.
