Role of Ultrasound Methods for the Assessment of NAFLD
No full textNonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. The prevalence in patients with type 2 diabetes mellitus is between 55–80%. The spectrum of NALFD ranges from simple steatosis to aggressive steatohepatitis with potentially progressive liver fibrosis up to cirrhosis and hepatocellular carcinoma. In clinical practice, there are two important aims: First to make the diagnosis of NAFLD, and second, to identify patients with advanced fibrosis, because extent of fibrosis is strongly associated with overall mortality, cardiovascular disease, hepatocellular carcinoma, and extrahepatic malignancy. Histology by liver biopsy can deliver this information, but it is an invasive procedure with rare, but potentially severe, complications. Therefore, non-invasive techniques were developed to stage fibrosis. Ultrasound is the primary imaging modality in the assessment of patients with confirmed or suspected NAFLD. This narrative review focus on different ultrasound methods to detect and graduate hepatic steatosis and to determine grade of fibrosis using elastography-methods, such as transient elastography and 2-dimensional shear wave elastography in patients with NAFLD. Particular attention is paid to the application and limitations in overweight patients in clinical practice. Finally, the role of B-mode ultrasound in NAFLD patients to screen for hepatocellular carcinoma is outlined
Induction of remission with tacrolimus in a patient with severe acute, cortisone refractory ulcerative colitis and severe Covid-19 pneumonia: a case report
No full textAbstract
Background
Therapy regimens used in patients with inflammatory Bowel Disease (IBD) have been associated with enhanced risk of viral infections or viral reactivation. Moreover, it is uncertain whether IBD patients have increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or infected patients may have an increased risk for severe coronavirus disease 2019 (Covid-19). Managing severe acute flare in ulcerative colitis during the Covid-19 pandemic is a challenge for clinicians and their patients. The results of the published studies mainly report on the role of the prior medication, but not how to treat severe acute flare of IBD patients with severe Covid-19 pneumonia.
Case presentation
We report the case of a 68-year-old patient with a long history of ulcerative colitis. He was initially admitted to an external hospital because of severe acute flare. The initiation of a high-dose oral cortisone therapy did not improve the clinical symptoms. During the inpatient treatment, he was tested positive for SARS-CoV-2. At admission to our hospital the patient showed severe flare of his ulcerative colitis and increased Covid-19 symptoms. A cortisone-refractory course was noticed. After detailed multidisciplinary risk–benefit assessment, we initiated an intravenous tacrolimus therapy and dose of prednisolone was tapered gradually. After clinical response, the therapy was adjusted to infliximab. Additionally, the Covid-19 pneumonia was kept under control despite immunosuppression and the patient could be discharged in clinical remission.
Conclusions
This case suggest the use of tacrolimus as a bridging therapeutic option for severe acute, cortisone refractory ulcerative colitis in Covid-19 patients. Nevertheless, the best treatment strategy for IBD patients presenting a flare during the outbreak has yet to be defined. Further data for IBD patients under calcineurin inhibitor therapy are urgently needed.Open-Access-Publikationsfonds 202

Mesenteric Masses on 2D Mode and Contrast-Enhanced Ultrasound: A Retrospective Study in 69 Patients
No full textAbstract
Purpose Detection of mesenteric masses (MM) by 2 D ultrasound often causes a diagnostic dilemma, and histological confirmation is required for definite diagnosis. The value of contrast-enhanced ultrasound (CEUS) for the diagnosis of MMs has not been investigated before. Here, we retrospectively evaluate 2D-mode and CEUS patterns of 69 patients with histologically confirmed MMs.
Materials and Methods Between January 2006 and January 2016, n = 69 patients were included in the study. Histopathological data, clinical data, 2D-mode ultrasound and CEUS enhancement were retrospectively analyzed.
Results More than half of the MMs (n = 47/69, 68 %) revealed a malignant histology. The size of the MM, inflammation markers and clinical symptoms did not correlate with the histological outcome. 2 D mode revealed n = 46 (67 %) lesions as hypoechoic, n = 14 (20 %) as hyperechoic, and n = 9 (13 %) with a complex echo pattern. Hypoechogenicity and complex echo patterns as well as regular borders of MMs were significantly associated with malignancy (p < 0.05). On CEUS, malignant MMs showed arterial hyperenhancement (n = 11/47, 23 %), isoenhancement (n = 25/47, 52 %) and hypoenhancement (n = 7/47, 15 %). The majority of malignant MMs (n = 42/47, 89 %) revealed parenchymal hypoenhancement. Benign masses revealed arterial hyperenhancement in n = 1/22 (5 %), isoenhancement in n = 8/22 (36 %), and hypoenhancement in n = 10/22 (45 %). The majority of lesions showed parenchymal hypoenhancement (n = 19/22, 86 %).
Conclusion Hypoechogenicity and complex echogenicity in 2 D mode, irregular borders, and parenchymal wash-out were more often associated with malignancy. However, CEUS did not help to subclassify malignant MMs according to their histological entity.</jats:p

Akute nekrotisierende Pankreatitis mit hämorrhagischem Schock bei sekundärer Milzruptur: Ein Fallbericht und Literaturübersicht
No full textZusammenfassung Die atraumatische Milzruptur ist eine seltene Komplikation der akuten und chronischen Pankreatitis. Sie entsteht aufgrund ihrer anatomischen Nähe zum Pankreas, beispielsweise als Folge der Erosion großer Pseudozysten oder Walled-of-Nekrosen (WON). Im Folgenden beschreiben wir den Fall einer 62-jährigen Patientin, welche sich zur weiteren Diagnostik und Therapie einer akuten Pankreatitis mit Ausbildung einer großen Walled-of-Nekrose (WON) im Pankreaskorpus und -schwanz vorstellte. Im Verlauf entwickelte die Patientin einen hämorrhagischen Schock. Eine Notfall-Computertomografie (CT) des Abdomens zeigte eine Milzruptur mit großem Kapselhämatom ohne den Nachweis einer aktiven Blutung. Im Gegensatz zu bereits publizierten Fällen wurde die Patientin ausschließlich minimalinvasiv therapiert: mittels radiologisch gesteuerter langstreckiger Embolisation der Arteria lienalis und mittels endosonografisch angelegtem Lumen-apposing Metall Stent (LAMS). Das Kapselhämatom zeigte sich unter einer Watch-and-wait-Strategie ohne sekundäre Drainage regredient
