Filter by:The goal of this prospective study is to validate the superior vena cava collapsibility index (SVC-CI) as a predictor of fluid responsiveness during laparotomy and open aortic surgery. The SVC-CI and patients' response to fluid will be assessed based on transesophageal echocardiography. The study has three arms, in order to validate SVC-CI under the conditions of laparotomy, aortic cross clamping and high PEEP levels. One of the study arms will be an active comparator arm. The data obtained from this study may help physicians guide intraoperative fluid therapy in a more efficient manner, in order to decrease perioperative mortality.
The researchers will conduct observations, interviews, and focus groups with clinicians, staff and patients of the Perioperative Optimization of Senior Health (POSH) clinic, which conducts preoperative comprehensive geriatric assessments (pCGA) at UW Health to understand clinic processes and potential areas for improvement. The goal is to (1) create a process map describing clinic workflow and (2) redesign the process with healthcare providers and patients/families.
The goal of this clinical trial is to test whether a new implementation package can help older adults prepare for major surgery. The main question it aims to answer is: Can the implementation package help give more people access to this resource? Participants will be in two groups: older adults who are planning a major surgery and their medical and surgical healthcare providers. The results will be compared to a historic baseline.
In the perioperative setting, Patient Reported Outcomes Measures (PROMs) are important for both patients and clinicians. Reliable PROMs, like the Quality Of Recovery 15 (QoR-15) questionnaire, are available for patients experiencing surgery. These PROMs are significantly used as endoints for clinical interventions assessment. These PROMs may also be considered to monitor and assess patient health status as part of enhanced recovery after surgery pathway. However data about the efficacy of PROMs-based perioperative clinical follow up are lacking. The clinical hypothesis is that a PROMs (QoR-15) based perioperative clinical care is more efficient that the usual care non based on the QoR-15.
Actual indications for stage Ia NSCLC patients suggest lobectomy and lymphadenectomy. On the other hand, recent studies reported non-inferiority of segmentectomy in case of nodule < 2cm or with ground glass appearance at computed tomography. However, most of these studies did not report specifical analysis on kind of segmentectomy (single or multiple) and kind of lobectomy. Moreover, a specific study on solid nodules only is still missing. For these reasons, the effectiveness of segmentectomy instead lobectomy for every kind of segment or tumor is still to be defined. Aim of this study is to analyze survival outcome in patients underwent single or multiple segmentectomy compared to lobectomy in stage I non small cell lung cancer.
The goal of this observational study is to conducted a comprehensive analysis of the factors contributing to redo- Pull-through surgery for constipation recurrence in Children who are suffering from Hirschsprun' s disease (HSCR) and its allied disorders (ADHD) . The main question[s] it aims to answer are: 1. Our study focused on the treatment and prognosis of these conditions, drawing upon 16 years of patient data and clinical experiences" 2. What are the key risk factors affecting the prognosis of recurrent constipation patients undergoing repeat PT?
The goal of this clinical trial is to test problem solving therapy (PST) in older adults who are undergoing major surgery. The main question it aims to answer is: • What is the feasibility and acceptability of delivering PST to older surgical patients with depressive symptoms or report lacking social support in the pre-operative and post-operative setting?
The trabeculectomy is the gold standard in glaucoma surgery, nevertheless often postoperative interventions have to be done. (1),(2) The PreserFlo MicroShunt (Santen, Osaka, Japan) implantation occurs without critical steps of trabeculectomy. (3) According to a study a 20% eye pressure reduction was achieved in 53.9% of patients one year after PreserFlo MicroShunt implantation and the risk of postoperative hypotony was clearly minimized. (4) It has been shown that after trabeculectomy there is a stable development of visual fields in the first 3 months after surgery and then, despite adequate intraocular pressure reduction, visual fields deteriorate. (5) At the Klinikum Klagenfurt structural and functional changes after PreserFlo MicroShunt Implantation shall be evaluated.
Individuals attending the hospital to undergo operations are at risk of developing blood clots in the legs, known as deep vein thrombosis (DVT). A clot in the leg can cause swelling, pain, and other long-term problems. If a clot in the leg breaks off and travels to the lungs, it can cause problems with the lungs' ability to move oxygen from the air into the blood and may be life-threatening. This is known as pulmonary embolism (PE). DVT and PE are known collectively as venous thromboembolism or VTE. The importance of preventing VTE in surgical patients is widely recognised, with two main strategies used: thinning the blood with regular injections and/or tablets and wearing elastic stockings to help stop blood from sitting in the leg veins where it can clot. Evidence for using elastic stockings to prevent VTE has recently been challenged. Additionally, there is a lack of evidence for the additional benefit of stockings over and above that of blood thinning medications. If stockings were to reduce VTE over and above blood thinning medication, these benefits need to be weighed against the risks and disadvantages of stockings, including discomfort, restricting blood flow to the leg causing blisters and wounds in addition to the cost. If stockings were found not to reduce the risk of clots, they would no longer need to be used in these patients, thus reducing the disadvantages of stockings, and saving the NHS millions of pounds per year. Certain types of operations (300,000 per year in the UK) are linked with a particularly high risk of VTE, including cancer surgery, surgery in the abdomen and pelvis, and bone (orthopaedic) surgery. In these cases, patients are offered blood thinning medications both during their hospital stay and for a period after they have left the hospital. Furthermore, these patients are offered stockings to wear while in the hospital. It is not known if, in patients who receive blood thinning medications both in hospital and after discharge, the addition of wearing stockings whilst in hospital reduces their risk of VTE any further. The purpose of this study is to investigate if it is worthwhile using stockings, in addition to blood thinning medication, to reduce blood clots after surgery. People enrolled in the study will be those at the highest risk of VTE and require an extended period of medication to reduce the risk of a blood clot. A computer will randomly choose one of the below treatments by chance to make the trial fair: A) Extended duration clot-reducing medicine in addition to stockings B) Extended duration clot-reducing medicine alone The surgery and all the other medical care will continue as normal. Everyone in the study will get an ultrasound scan at 21 - 35 days after their operation to check if they have developed a blood clot. This is an additional scan, not routinely performed in the NHS, to make sure that all blood clots are detected at an early stage. Participants will receive a phone call at 7, 21-35 and 90 days after their treatment to see if they have developed a blood clot or had any problems with the treatment.
Patients with locally advanced gastric adenocarcinoma (CT2-4a N-/+ M0) were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in 3D plus ultra high resolution laparoscopic gastrectomy with lymph node dissection for gastric cancer.
