    Abstract Background: Anastomotic leakages after esophagectomies continue to constitute significant morbidity and mortality. Intrathoracic anastomoses pose a high risk for mediastinitis, sepsis, and death, if a leak is not addressed timely and appropriately. However, there are no standardized treatment recommendations or algorithms as for how to treat these leakages.
    Methods: The study included all patients at the University Hospital Regensburg, who developed an anastomotic leakage after esophagectomy with gastric pull-up reconstruction from 2007 to 2022. Patients receiving conventional treatment options for an anastomotic leakage (stents, drainage tubes, clips, etc.) were compared to patients receiving endoscopic vacuum-assisted closure (eVAC) therapy as their mainstay of treatment. Treatment failure was defined as cervical esophagostomy formation or death.
    Results: In total, 37 patients developed an anastomotic leakage after esophagectomy with a gastric pull-up reconstruction. Twenty patients were included into the non-eVAC cohort, whereas 17 patients were treated with eVAC. Treatment failure was observed in 50% of patients (n = 10) in the non-eVAC cohort and in 6% of patients (n = 1) in the eVAC cohort (p < 0.05). The 90-day mortality in the non-eVAC cohort was 15% (n = 3) compared to 6% (n = 1) in the eVAC cohort. Cervical esophagostomy formation was required in 40% of cases (n = 8) in the non-eVAC cohort, whereas no patient in the eVAC cohort underwent cervical esophagostomy formation.
    Conclusion: eVAC therapy for leaking esophagogastric anastomoses appears to be superior to other treatment strategies as it significantly reduces morbidity and mortality. Therefore, we suggest eVAC as an essential component in the treatment algorithm for anastomotic leakages following esophagectomies, especially in patients with intrathoracic anastomoses.

    Abstract Despite one of the largest vaccination campaigns in human history, the COVID-19 pandemic has not been yet defeated. More than 10 billion doses of COVID-19 vaccine have been administered worldwide. AstraZeneca's Vaxzevria (ChAdOx1 nCoV-19 / AZD1222) was approved as the first viral vector-based vaccine in the EU on 29 January 2021. Thromboembolic events are a rare complication of vaccination with ChAdOx1 nCoV-19 in the context of, now known as vaccine-induced immune thrombotic thrombocytopenia (VITT), with an incidence of 1.5-3 in 100,000 vaccinations. VITT is clinically as well as pathophysiologically comparable to heparin-induced thrombocytopenia. Illustrated by a fulminant patient case, a multidisciplinary step-by-step guideline was developed for the recognition, diagnosis, and management of patients with severe acute portosplanchic venous thrombosis with mesenteric ischemia due to vaccine-induced immunogenic thrombotic thrombocytopenia.

    Abstract Eosinophilic cholangitis is a rare clinical entity characterised by transmural eosinophilic infiltration of the biliary system. The aetiology of this disease is still unclear. We report on a 49-year-old male patient who presented with symptoms of obstructive jaundice and imaging suggestive for periampullary carcinoma. After partial pancreatoduodenectomy for suspected pancreatic cancer, pathology revealed massive eosinophilic cholecystitis as well as intra- and extrahepatic eosinophilic cholangitis with pseudopolypoid papillary lesions. Our case illustrates the diagnostic pitfalls in eosinophilic cholangitis as careful imaging procedures - optimally interdisciplinary - should be considered and performed in such patients. In conclusion, eosinophilic cholangitis is an uncommon, inflammatory condition that needs to be considered as a differential diagnosis for periampullary malignancies.

    Abstract Introduction: The essential prerequisite for successful gene therapy in vivo is an effective and long-lasting transfer of the desired gene into the respective cell type or tissue. Over the last decades, many different methods have been developed for this purpose. The use of plasmid DNA seems to be a good alternative to the commonly used viral vectors because its large-scale production is simple, and side effects are low. Unfortunately, most reports describe only short-term expression in vivo, probably due to the lack of genomic integration in the target cell. This problem can possibly be addressed by the use of adeno-associated virus plasmids (AAV plasmids), where the coding sequences are cloned between the AAV-specific inverted terminal repeats. Here, we report our results after allogeneic heart transplantation, which followed AAV-plasmid-mediated gene transfer of the rat soluble major histocompatibility complex class I antigen RT1.A(a) and viral interleukin (vIL)-10 in the "high"-responder Dark Agouti to Lewis rat strain combination.
    Results: A high and stable long-term expression was achieved by in vivo transfection of the liver using AAV plasmids. Serum levels over 1,000 ng/ml of soluble RT1.A(a) and over 300 pg of vIL-10, respectively, were achieved. Expression levels remained high for up to several months. A mean prolongation of heart allograft survival of 1 to 2 days was demonstrated after transfection of either RT1.A(a) or vIL-10.

    Abstract Background: Portal vein thrombosis (PVT) is a surgical challenge in liver transplantation (LTx). In contrast to LTx in decompensated liver disease, which are associated with a higher morbidity and mortality, PVT influence on outcome is still under debate. To evaluate this influence at different stages of liver decompensation, we compared the outcome of patients suffering from PVT to patients with patent portal vein within different score ranges.
    Methods: We included 193 LTx (24 with PVT) in our study, transplanted between 2004 and 2007 at our institution. Patients were divided into four Model of End-Stage Liver Disease (MELD) score groups, and outcome was compared between PVT- and non-PVT patients.
    Results: In non-decompensated liver disease (MELD <15), we found a significantly decreased survival in patients suffering from PVT (one-yr survival 57% vs. 89%). By contrast, MELD score >15 (decompensated liver disease) leads to an equal or even better survival in PVT-patients compared with patients without PVT (one-yr survival 91% vs.75%), with an only slightly increased morbidity.
    Conclusion: Outcome in patients with PVT seems to be dependent on pre-operative disease severity. In contrast to compensated liver disease, no influence of PVT on outcome could be found in decompensated liver disease, and should therefore not be considered as a contraindication in LTx.

    Abstract Die hereditäre Tyrosinämie Typ 1 (HT-1), die durch eine Mutation im Fumarylacetoacetathydrolase (fah) Gen verursacht wird, führt unbehandelt bereits in den ersten Lebensjahren zu zirrhotischem Leberversagen und zu hepatozellulärem Karzinom. Seit einigen Jahren ist für diese Erkrankung eine effektive medikamentöse Therapie, eine Substratinhibition durch NTBC (2–2-nitro-4-fluoromethylbenzoyl-1,3-cyclohexanedione) verfügbar. Trotz medikamentöser Therapie gibt es eine hohe Inzidenz an Leberdefekten in diesen Patienten. Hier wird eine alternative Therapie der HT-1 durch DNA-Injektion am Tiermodell vorgestellt. Dazu wurde murines fah-Gen zwischen AAV-spezifische ITRs in ein pSUB 201 Vektorsystem kloniert. Im Gegensatz zu anderen (Retro-)viralen Vektorsystemen ist dieser Vektor geeignet die insertionale Mutagenese zu minimieren. Fah knock out Mäusen wurde intravenös 1,2µg/kg Körpergewicht dieser DNA in einem großen Volumen (100µl/g Körpergewicht) appliziert. Die Vektoraufnahme und FAH-Produktion wurde nach 100 Tagen durch immunhistochemische Färbung der Leber kontrolliert, eine Repopulation der Leber mit FAH produzierenden Zellen wurde durch Ausüben eines Selektionsdrucks für die plasmidtragenden Zellen erwirkt (NTBC-Entzug). Ferner wurde der Therapieerfolg anhand der metabolischen Leberparameter quantifiziert. Alle behandelten Tiere überlebten den Entzug des Medikamentes NTBC mehr als 100 Tage ohne weitere pharmakologische Unterstützung. Die Lebern dieser Tiere waren mit bis zu 50% FAH positiven Hepatozyten besiedelt und die metabolischen Serumparameter erreichten annähernd Wildtypniveau, während das Lebergewebe morphologisch gesund aussah. Damit stellt die Applikation des pSUB 201 fah-Plasmids mit AAV-spezifischen ITRs eine alternative Therapie für die Behandlung von HT-1 dar. Diese ersten Langzeitversuche im HT-1-Tiermodell zeigten keine negativen Nebeneffekte. In weiteren Versuchen müssen die Vektorintegration und die damit verbundenen Risiken evaluiert werden.

    Abstract The isolation of rearranged immunoglobulin (Ig) variable region (V) genes is usually performed by PCR with consensus primers binding to conserved regions within the V sequences. However, the isolation of Ig genes by this method is hampered in 15-35% by technical difficulties, mostly mismatches of oligonucleotide primers to V sequences. In order to obtain DNA sequences from V heavy chain (VH) genes which could not be amplified with consensus primers, we used a modified PCR technique, the rapid amplification of cDNA ends (RACE) PCR in combination with new heavy chain constant region primers for the isolation of human and murine VH genes. In comparison, consensus primer PCR with different sets of previously published oligonucleotide primers was used. Both methods were applied to isolate VH genes from murine B cell lymphoma (A20 and BCL1), myeloma (NS1) and hybridoma (SP6) cell lines and from freshly isolated human chronic lymphocytic leukemia and lymphoma cells. RACE PCR allowed the amplification and subsequent cloning of the complete VH gene in all cases. In contrast, consensus primer PCR failed to isolate the VH sequence of the murine A20 cell line; this was explained by a mismatch of consensus primers with VH sequences. When both PCR methods amplified VH sequences, the DNA sequences obtained were identical. Taken together, RACE PCR represents a reliable and versatile method for the isolation of VH genes from human and murine lymphoma cells, in particular if consensus primer PCR fails.
