Initial robotic assistance in the surgical management of renal cell carcinoma with level 4 cavoatrial thrombus

We report a case of left-sided renal cell carcinoma (RCC) with level 4 cavoatrial tumor thrombus where robotic assistance was used to achieve hemostasis around the kidney in order to minimize coagulopathic hemorrhage from the nephrectomy bed during subsequent open completion nephrectomy and cavoatrial thrombectomy under extracorporeal circulation and hypothermic circulatory arrest. Robotic assistance allowed for meticulous dissection and ligation of parasitic and arterial vessels to the kidney, release of renal attachments, and exposure of the inferior vena cava. The kidney was mobilized while leaving the renal vein attached and tumor thrombus undisturbed using a “minimal touch” technique. Open completion nephrectomy and cavoatrial thrombectomy was then performed. An experienced cardiac anesthesia team performed intraoperative cardiac monitoring, including trans-esophageal echocardiography. A cardiothoracic surgeon was immediately available throughout th e case. Cardiopulmonary bypass was initiated within 60 min of open incision with a total duration a circulatory arrest time of 25 min. There was no bleeding from the nephrectomy bed during bypass despite heparinization and hypothermia. A left RCC with level 4 thrombus may be approached with initia l robotic assistance to achieve hemostasis of the nephrectomy bed for subsequent open completion nephrectomy and cavoatrial thrombectomy under extracorporeal circulation and hypothermic circulatory arrest.

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...

In this study, an attempt to oxidise the surface of a commercial activated carbon to improve its adsorption capacity for sevoflurane was conducted using 6 mol/L nitric acid, 2 mol/L ammonium persulfate, and 30 wt per cent (wt%) of hydrogen peroxide (H2O2). The adsorption tests at fixed conditions (bed depth: 10 cm, inlet concentration: 528 mg/L, and flow rate: 3 L/min) revealed that H2O2 oxidation gave desirable sevoflurane adsorption (0.510 ± 0.005 mg/m2). A parametric study was conducted with H2O2 to investigate the effect of oxidation conditions to the changes in surfa...

ConclusionWe consider that this technique is useful, however, we have to exercise care in malignant cases as the true-positive rate may be low.

ConclusionThe more invasive approach does not correlate to a better outcome. In selected cases, DR is an oncologically safe technique; EBR is still a valid option to treat advanced oral cancers
