Zusammenfassung 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.

Abstract The COVID-19 pandemic poses new challenges for the medical community due to its large number of patients presenting with varying symptoms. Chest ultrasound (ChUS) may be particularly useful in the early clinical management in suspected COVID-19 patients due to its broad availability and rapid application. We aimed to investigate patterns of ChUS in COVID-19 patients and compare the findings with results from chest X-ray (CRX). 24 patients (18 symptomatic, 6 asymptomatic) with confirmed SARS-CoV-2 by polymerase chain reaction underwent bedside ChUS in addition to CRX following admission. Subsequently, the results of ChUS and CRX were compared. 94% (n=17/18) of patients with respiratory symptoms demonstrated lung abnormalities on ChUS. ChUS was especially useful to detect interstitial syndrome compared to CXR in COVID-19 patients (17/18 vs. 11/18; p<0.02). Of note, ChUS also detected lung consolidations very effectively (14/18 for ChUS vs. 7/18 cases for CXR; p<0.02). Besides pathological B-lines and subpleural consolidations, pleural line abnormality (89%; n=16/18) was the third most common feature in patients with respiratory manifestations of COVID-19 detected by ChUS. Our findings support the high value of ChUS in the management of COVID-19 patients.

Abstract Background and aims With an external additional working channel (AWC) endoscopic mucosal resection (EMR) as well as endoscopic submucosal dissection (ESD) can be extended to techniques termed “EMR+” and “ESD+.” These novel techniques are systematically compared to EMR and ESD under the use of a double-channel endoscope (DC). Methods Our trial was conducted prospectively in a pre-clinical porcine animal model (EASIE-R simulator) with standardized gastric lesions measuring 3 or 4 cm. Results EMR+ and EMR DC showed both good results for 3 cm lesions with no adverse events and an en bloc resection rate of 73.33% (EMR+) and 60.00% (EMR DC, p  = 0.70). They came to their limits in 4 cm lesions with muscularis damages of 20.00% (EMR+), 13.33% (EMR DC, p  ≥ 0.99) and decreasing en bloc resection rates of 60.00% (EMR+) and 46.67% (EMR DC, p  = 0.72). ESD+ and ESD DC were both reliable concerning en bloc resection rates (100% in all groups) and adverse events (0.00% in 3 cm lesions, 12.50% muscularis damages in both ESD+ and ESD DC in 4 cm lesions). Resection time was slightly shorter in all groups with the AWC compared to DC although only reaching significance in 3 cm ESD lesions ( p  < 0.05*). Conclusions With the AWC, a standard endoscope can easily be transformed to double-channel functionality. We could show that EMR+ and ESD+ are non-inferior to EMR and ESD under the use of a double-channel endoscope. Consequently, the AWC presents an affordable alternative to a double-channel endoscope for both EMR and ESD.
