9. Differentiated surgical approach for adenocarcinoma of the gastroesophageal junction

Author

Schroeder, W., Lambertz, R., van Hillegesberger, R., Bruns, C., Schroeder, W., Lambertz, R., van Hillegesberger, R., and Bruns, C.

Abstract

For adenocarcinoma of the gastroesophageal junction (GEJ) the classification of Siewert with its three subtypes is well established as a practical approach to surgical treatment. Transthoracic esophagectomy with gastric tube formation is generally accepted as the surgical standard for adenocarcinoma of the distal esophagus (GEJ type I). Intrathoracic esophagogastrostomy has become the most frequently used anastomotic technique (Ivor Lewis esophagectomy). Both the abdominal and thoracic part can be safely performed with a minimally invasive access. For subcardiac gastric cancer (GEJ type III) transhiatal extended gastrectomy is the resection of choice. For true cardiac carcinomas (GEJ type II) it has not yet been decided which of the abovementioned surgical procedures offers the best long-term survival. If technically possible in terms of a complete resection, transhiatal extended gastrectomy should be preferred because of a better postoperative quality of life. For GEJ type II tumors a minimally invasive approach is not recommended if the extent of resection cannot be safely determined preoperatively.

10. Perioperative management of transthoracic oesophagectomies. Fundamentals of interdisciplinary care and new approaches to accelerated recovery after surgery

Author

Abstract

Locally advanced carcinomas of the oesophagus require multimodal treatment. The core element of curative therapy is transthoracic en bloc oesophagectomy, which is the standard procedure carried out in most specialized centres. Reconstruction of intestinal continuity is usually achieved with a gastric sleeve, which is anastomosed either intrathoracically or cervically to the remaining oesophagus. This thoraco-abdominal operation is associated with significant postoperative morbidity, not least because of a vast array of pre-existing illnesses in the surgical patient. For an optimal outcome, the careful interdisciplinary selection of patients, preoperative risk evaluation and conditioning are essential. The caseload of the centres correlates inversely with the complication rate. The leading surgical complication is anastomotic leakage, which is diagnosed endoscopically and usually treated with the aid of endoscopic procedures. Pulmonary infections are the most frequent non-surgical complication. Thoracic epidural anaesthesia and perfusion-orientated fluid management can reduce the rate of pulmonary complications. Patients are ventilated protecting the lungs and are extubated as early as possible. Oesophagectomies should only be performed in high-volume centres with the close cooperation of surgeons and anaesthesia/intensive care specialists. Programmes of enhanced recovery after surgery (ERAS) hold further potential for the patient's quicker postoperative recovery. In this review article the fundamental aspects of the interdisciplinary perioperative management of transthoracic oesophagectomy are described.

Abstract

The highly infectious disease COVID-19 caused by the Betacoronavirus SARS-CoV-2 poses a severe threat to humanity and demands the redirection of scientific efforts and criteria to organized research projects. The international COVID19-NMR consortium seeks to provide such new approaches by gathering scientific expertise worldwide. In particular, making available viral proteins and RNAs will pave the way to understanding the SARS-CoV-2 molecular components in detail. The research in COVID19-NMR and the resources provided through the consortium are fully disclosed to accelerate access and exploitation. NMR investigations of the viral molecular components are designated to provide the essential basis for further work, including macromolecular interaction studies and high-throughput drug screening. Here, we present the extensive catalog of a holistic SARS-CoV-2 protein preparation approach based on the consortium’s collective efforts. We provide protocols for the large-scale production of more than 80% of all SARS-CoV-2 proteins or essential parts of them. Several of the proteins were produced in more than one laboratory, demonstrating the high interoperability between NMR groups worldwide. For the majority of proteins, we can produce isotope-labeled samples of HSQC-grade. Together with several NMR chemical shift assignments made publicly available on covid19-nmr.com, we here provide highly valuable resources for the production of SARS-CoV-2 proteins in isotope-labeled form., This work was supported by Goethe University (Corona funds), the DFG-funded CRC: “Molecular Principles of RNA-Based Regulation,” DFG infrastructure funds (project numbers: 277478796, 277479031, 392682309, 452632086, 70653611), the state of Hesse (BMRZ), the Fondazione CR Firenze (CERM), and the IWB-EFRE-program 20007375.

Abstract

The current outbreak of the highly infectious COVID-19 respiratory disease is caused by the novel coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). To fight the pandemic, the search for promising viral drug targets has become a cross-border common goal of the international biomedical research community. Within the international Covid19-NMR consortium, scientists support drug development against SARS-CoV-2 by providing publicly available NMR data on viral proteins and RNAs. The coronavirus nucleocapsid protein (N protein) is an RNA-binding protein involved in viral transcription and replication. Its primary function is the packaging of the viral RNA genome. The highly conserved architecture of the coronavirus N protein consists of an N-terminal RNA-binding domain (NTD), followed by an intrinsically disordered Serine/Arginine (SR)-rich linker and a C-terminal dimerization domain (CTD). Besides its involvement in oligomerization, the CTD of the N protein (N-CTD) is also able to bind to nucleic acids by itself, independent of the NTD. Here, we report the near-complete NMR backbone chemical shift assignments of the SARS-CoV-2 N-CTD to provide the basis for downstream applications, in particular site-resolved drug binding studies.

14. Ultrasound-guided lymphangiography and interventional embolization of chylous leaks following esophagectomy.

Author

Abstract

Objectives: Postoperative chylothorax is a serious complication after transthoracic esophagectomy, and is associated with major morbidity due to dehydration and malnutrition. For patients with high-output fistula, re-thoracotomy with ligation of the thoracic duct is the treatment of choice. Radiologic interventional management is an innovative procedure that has the potential to replace surgery in the treatment algorithm., Methods: Four patients with high-output chylous leaks following esophagectomy are presented. Ultrasound-guided lymphangiography with embolization of the thoracic duct and/or disruption of the cisterna chyli was performed to occlude the leakage site. Radiologic interventions and procedure-related outcomes are described in detail., Results: In all four patients, ultrasound-guided lymphangiography of the groin with injection of Lipiodol was able to detect and visualize the leakage site in the lower mediastinum. In three patients, the leak could be successfully occluded by Lipiodol embolization. In one patient, embolization failed and the disruption technique was successfully performed. No procedure-related complications were observed., Conclusions: In case of a postoperative chylothorax, radiologic intervention is feasible and safe. The procedure is indicated for high-output chylous fistulas after esophagectomy, and should be applied early after the diagnosis of this postoperative complication., (©2019 Lambertz R., et al., published by De Gruyter, Berlin/Boston.)
