Filter by:Gastric conduit ischemia or anastomotic breakdown after esophagectomy with cervical esophagogastrostomy often cause severe complications, such as leakage, necrotic organs, and strictures. Thus, the purpose of this study is the safety and efficacy of endoscopic evaluation about reconstructive organs after esophagectomy. The investigators evaluate endoscopic predictions using classifications in acute phase after esophagogastrostomy.
Back pain is a huge problem for millions of Americans, including nearly 11 million Veterans. Our older Veterans suffer the most. Citizens spend billions of dollars, yet consistently get poor results. Primary Care Providers are often tasked with diagnosing and treating Chronic Low Back Pain, even though they are often undereducated in the field. These PCPs often use advanced imaging, usually MRIs to guide care. These images often show degenerative disc disease and other common pathologies in older adults, even those who are pain free, which can lead to misdiagnosis and treatment. The investigators believe that Chronic Low Back Pain is a syndrome, a final common pathway for the expression of multiple contributors that often lie outside the spine itself. For example, hip osteoarthritis, knee pain, and even anxiety could all lessen back pain if addressed and treated probably. Investigators will measure participants' low back pain-associated disability with the well-validated RMDQ. Data will be collected at baseline and monthly via telephone. The investigators hypothesize that veterans who receive PCCET will experience significantly greater reduction in low back pain-associated disability than those who receive IAUC at six months. Investigators will also measure participants' low back pain with the 0-10 Numeric Rating Scale for Pain. Data will be collected at baseline and monthly via telephone. The investigators hypothesize that veterans who receive PCCET will experience significantly greater reduction in low back pain than those who receive IAUC at six months. The goal of this study is to compare patients treated with usual care, which usually starts with imaging, versus patients who are treated by trained geriatricians who know how to recognize and address 11 key conditions that commonly drive pain and disability in older adults. The investigators believe that older patients who receive care tailored to their needs by educated PCPs will ultimately have less back pain and, more importantly, better quality of life.
Cardiac output monitoring devices are commonly used in ICU patients. The most precise use direct measurement, which require artery cannulation. The gold standard is Swan-Ganz catheter, but it is a very invasive technique. PiCCO (Pulse index Continuous Cardiac Output) is the alternative way of haemodynamic monitoring. This technology is the easy, less invasive and cost-efficient tool for determining the main hemodynamic parameters of critically ill patients. It is based on two physical principles - transpulmonary thermodilution and pulse contour analysis. Both principles allow the calculation of haemodynamic parameters in critically ill patients. PiCCO method requires peripheral artery cannulation. Cannulation may be followed by artery stenosis. Aims of the study are: 1. to verify the occurrence of radial artery stenosis after 3 days of having a PiCCO cannula in place. 2. whether 5 days cannulation of radial artery with PiCCO catheter is related to more frequent stenosis rate. An additional assessment: 1. to check whether the eventual stenosis is still present after 3, 14 and 30 days after decannulation - assessment depending on patients availability
Patients with symptomatic or asymptomatic carotid stenosis in whom carotid artery stenting is planned are randomised between antiplatelet therapy with ticagrelor plus aspirin or clopidogrel plus aspirin and examined with brain MRI before and after stent treatment. The proportion of patients with new ischaemic lesions on MRI after treatment is compared between the two groups.
Crohn's disease （CD） with stenosis has limited therapeutic options and with high surgical rate. The present clinical trial aims to evaluate the efficacy and safety of rapamycin in the treatment of stricturing Crohn's Disease.
To establish the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) in patients with severe, calcific aortic stenosis who are at low operative risk for standard aortic valve replacement.
The studied pathology concerns post traumatic cervical spinal cord contusion on narrow spinal canal. The pathophysiology remains controversial. This pathology does not enjoy consensus support. Many questions remain regarding the surgical care and its delay. The purpose of the study was to demonstrate non-inferiority of early surgical treatment compared to the same surgery performed with a delay among patients identified as having a cervical spinal cord contusion on posttraumatic narrowed cervical canal. In the current state of knowledge and practices, the treatment of post traumatic spinal cord contusions on narrow spinal canal spinal decompression is performed remote diagnosis. The generally accepted delay is 15 days. The surgical technique is a conventional cervical spinal decompression surgery. The type of decompression (anterior or posterior) is dependent on the compression and therefore the clinical radiological analysis. The choice of the technique and the surgical approach are therefore left to the discretion of the surgeon. After completion of the clinical and radiological diagnosis of post-traumatic spinal cord contusion on narrow spinal canal, the patient was hospitalized in intensive care or in the Neurosurgery Service of the University Hospital concerned. After anesthetic consultation determining the feasibility or not of surgery and in the absence of other vital injury or involving life-threatening, early surgery within 48 hours of diagnosis is then considered (according to the assigned group). The surgical technique is a conventional cervical spinal decompression surgery. Way posterior surgery, laminectomy for spinal stenosis significant if greater than or equal to 3 floors will be preferred. In other cases, the type of surgery will be at the discretion of the surgeon and the opinion of the Staff Neurosurgery. The surgical procedure is identical in the two groups. Alone, the delay of the surgery varies : less than 48 hours for the first group and 15 days for the second. During the different monitoring visits (D0 (surgery), D7, M3, Y1 and Y2), the following criteria will be assessed : the quality and quickness of the motor and sensory recovery, the early post-operative evolution and the long and medium term evolution but also disability and functional sequelaes.
ATLANTIS is a multicenter, phase IIIb, prospective, open-label, randomized trial. The objective of this study is to demonstrate superiority of a strategy of anticoagulation with apixaban (Anti-Xa Group) as compared to the current standard of care in patients who have undergone a successful TAVI procedure. The randomization is stratified according to the presence or not of a mandatory indication for anticoagulation for a reason other than the TAVI procedure (e.g. atrial fibrillation or DVT/PE).
A prospective, multicenter, single-arm, open label clinical study to evaluate the safety and effectiveness of MicroVention, Inc. Roadsaver™ Carotid Stent System used in conjunction with the Nanoparasol® embolic protection system for the treatment of carotid artery stenosis in patients with elevated risk for adverse events following carotid endarterectomy.
The objective of this study is to assess the safety and effectiveness of the COVERA™ Vascular Covered Stent for the treatment of stenotic lesions in the upper extremity venous outflow of the Arteriovenous (AV) access circuit.
