Filter by:Resection of brain tumours forms a large proportion of work in brain surgery. One important aspect is to minimize damage to normal brain structures during this process. This improves patient outcomes and reduces complications. To identify normal brain structures from the abnormal tumours, the brain surgeons use a 'guidance' technique called intraoperative neuro-monitoring (IONM). IONM uses various electrodes to observe spontaneous electrical activity of the brain or its reaction to a stimulus such as muscle contraction, light or sound. It is now becoming common practice for neurosurgeons to use this tool during brain and spinal surgery to provide a real-time feedback under anaesthesia to help them minimise injury to important and normal brain and spine structures. IONM interpretation needs fulfilment of multiple preconditions and major modifications to the anaesthetic to reduce its inaccuracies. This invites added risks and complications such as awareness, convulsions and heart problems under anaesthesia. A team approach between the surgeon, anaesthetist and neurophysiologist (IONM specialist) is also crucial to obtain meaningful results. Therefore, the usefulness of this technique is still not perfect. Although, benefits of IONM are obvious, information on associated complications and patient experience are not commonly found in the literature. Information on other effects such as hormonal balance and tumour recurrence are also scarce. In general, these aspects have little scientific exploration. There are anecdotal reports of recurrent seizures during IONM leading to serious heart problems, teeth and tongue damage due to grinding and postoperative calf muscle injury necessitating further surgery to save limbs. Neither of these is in the literature including unorthodox treatments such as the use of cold saline to control IONM triggered fits. This study is designed to observe complications and outcome and explore patient experiences following IONM in an observational capacity not interfering with the clinical management or treatment of these patients. The investigators intend to interview the participants after surgery, at a convenient time before leaving hospital to understand their views and experiences during and after surgery and their general progress in the following one year.
This clinical trial evaluates the efficacy and safety of axillary versus cephalic venous access in the pacemakers and defibrillators implantation. Half of participants will receive the implant via fluoroscopy guided axillary venous access and the other half will receive the implant via improved cephalic venous access.
The primary focus in this study is to investigate and improve the surgical technique. In addition the collection of clinical data during diagnostic and follow up and the collection of tumor and blood gives us the opportunity to investigate tumor biology and its relevance in terms of determine appropriate treatment strategy both surgically and oncological and to assess and predict treatment outcome. The aim of this study is to compare short and long-term outcomes between open D3 and laparoscopic CME (complete mesocolic excision) with CVL (central vascular ligation) right colectomy for right-sided colon cancer. Our primary hypothesis is that laparoscopic surgery improves quality of life by reducing pain, postoperative complications and thereby reduces hospital stay and convalescence. On the other hand it is to prove non-inferiority of the laparoscopic group compared to the open group by means of oncological outcome (survival, recurrence). Secondary aim is to evaluate surgical quality by comparing actual vascular stump length between the two groups by postoperative CT and compare number of lymph nodes removed with the specimen. With the use of liquid biopsy we want to detect circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs) and evaluate their value as tumor markers by comparing the prognostic and predictive value. The hypothesis is that ctDNA and CTCs are more sensitive than standard parameters and imaging (CT CEA).
Enrollment criteria and clinical data collection: following the principles of medical ethics, the development of inclusion and exclusion criteria. Selecting 200 cases of chronic venous disease (CVD) according to the Comprehensive Classification System for Chronic Venous Disorders (CEAP) divided into 6 Clinical stages (C1-C6) (Group A). Selecting 200 healthy participants without CVD (C0) as controls (Group B). Blood samples will be collected from both groups. Markers of pyroptosis (NETs, Caspase-1 and Cytokines) will be evaluated between the two groups and between the subgroups, according to clinical stage, in group A.
Chronic pancreatitis (CP) is a disease characterized by inflammation and their replacement by fibrotic tissue. The destruction of pancreatic function and structure are the main complications. This retrospective-prospective, multicenter, cohort study was conducted. This study aimed to observe the natural history of CP in China, analyse the risk factors for CP complications, and establish individual predictions.
This is a randomised double-blinded placebo-controlled phase IV trial with two parallel treatment groups receiving either immune nutrition diet (IND) or conventional diet for 2weeks peri-radical cystectomy. Patients will be stratified according to the gender, body mass index, and the type of urinary diversion (orthotopic neobladder or ileal conduit). The primary end-point is to determine, in intention to treat analysis, the influence of IND on 90-day postoperative morbidity. Secondary study end-points will be the effect of IND on infectious as well as non-infectious complications over 90 days, compliance and adverse effects of IND. Finally, an ancillary study will be performed to evaluate whether the IND costs could counterbalance, by its benefits, the health care costs.It is envisaged to finish patients' recruitment within 24 months
To date no study has determined prospectively which technique is superior to prevent recurrent Pelvic Organ Prolapse (POP) after vaginal hysterectomy- a major unmet clinical need. The aim of the study is to determine objective anatomical recurrent prolapse after Sacrospinous Ligament Fixation (SLF) vs McCall.
