Clinical trials Below are current clinical trials.122 studies in Surgery (open studies only). Filter this list of studies by location, status and more. A Registry Called Every Child for Collecting Data and Biology Specimens on Younger Patients with Cancer Rochester, Minn. The purpose of this registry called Every Child, is to collect data and biospecimens from multiple body sources for younger patients with cancer over time. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care. A Study To Evaluate Mesenchymal Stem Cells For Reducing Anastomotic Stenosis Jacksonville, Fla. The purpose of this study is evaluate the safety of allogeneic adipose derived mesenchymal stem cell (AMSC) use during hemodialysis arteriovenous fistula and arterial bypass creation and its effectiveness on improving access maturation and primary anastomotic patency. Pituitary tumor registry Rochester, Minn. The purpose of this data registry involves the collection of standard of care clinical treatment regimens, diagnostic information and surgical outcomes which may include human specimens and associated genomewide expression data. CT Angiography of the Aorta following Fenestrated Branched Endovascular Aneurysm Repair (F-BEVAR) using Tube Potential Selection and Weight-based Method: Effects on Image Quality and Radiation Dose Rochester, Minn. The objective of this study is to evaluate the image quality and radiation dose of a CT angiography protocol (CTA) using tube potential selection and weight-based method. A Study To Evaluate The Impact Of Non-invasive Tests For Bladder Cancer Rochester, Minn. Levels of bladder cancer-derived extracellular vesicles become undetectable after radical cystectomy in patients with localized bladder cancer. This study hopes to determine the levels of bladder cancer-derived extracellular vesicles pre- and post-RC. A Study to Establish a Pediatric Spine Registry Rochester, Minn., Minneapolis, Minn. The purpose of this study is to collect data about patients with chest wall and spinal deformities to develop a multicenter registry. This will speed the pace of medical advancement and treatment recommendations for these conditions. A Study to Analyze Intracerebral Hemorrhage Hematoma Jacksonville, Fla. The purpose of this study is to to take the usual waste material from the removal of hematoma and apply an array of -Omics approaches (including for example genomics, transcriptomics, lipidomics, proteomics, and metabolomics) to identify biomarkers that assess prognosis and identify key therapeutic targets. A Study to Establish a Registry for Treatment of Post-hemorrhagic Hydrocephalus in Neonates Rochester, Minn. The purpose of this study is to establish a prospective, standardized data collection for the patients who undergo surgical treatment of progressive post-hemorrhagic hydrocephalus in neonates with the focus on comparing neuroendoscopic lavage (NEL) with other standard treatment options such as external ventricular drainage (EVD), ventricular access device (VAD) and ventricular subgaleal shunt (VSGS). Mayo Clinic Cancer Center Neuro-Oncology Program Registry And Biobank For The Study Of Nervous System Tumors Rochester, Minn. Biospecimen banks are a modern attempt to centralize collections of human blood and tissue samples along with health information and personal history. The Neuro-Oncology Program Registry and Biobank will be used for research purposes to increase our understanding of nervous system tumors. Intraoperative Contrast Enhanced Ultrasound for the Identification of Pituitary Adenoma in Cushing’s Disease Rochester, Minn. The purpose of this study is to combine recent advances in ultrasound imaging, specifically an endonasal transducer array and contrast enhanced ultrasound, to offer an intraoperative image-guided solution for lesion-specific surgical resection to impact clinical outcome.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
