Filter by:The investigators aim to assess the efficacy of the Curaseal anal plug in patients with idiopathic uncomplicated fistulous tracts. Healing of the fistula tract will be assessed both clinically and radiologically with MR imaging.
Compare the effectiveness of drug-coated balloons to plain balloon angioplasty in reducing stenosis rates in dialysis arteriovenous fistulas (AVFs).
The objective of this pilot study is to evaluate the feasibility, safety and efficacy of 3M™ Cavilon™ Advanced Skin Protectant when used in the management of damaged skin exposed to caustic body fluids from an ostomy, drain site or fistula.
Dysfunctions such as tight stenosis or thrombosis in haemodialysis vascular accesses are the leading cause of hospitalisationand morbidity in chronic haemodialysis patients incurring significant related costs estimated at over one billion dollars in the USA. Dysfunctions of these vascular accesses are generally treated by conventional angioplasty as this is the least invasive procedure, the alternative being revision surgery. Angioplasty uses an inflatable balloon of various diameters. Different types of angioplasty balloons may be needed to break fibrous venous stenosis, in particular high-pressure balloons or cutting balloons. These angioplasty procedures which are often painful during dilation have a high technical success rate but a poor 1-year patency rate. These invasive repeated procedures impair the quality of life of these patients with end-stage renal disease who are on permanent dialysis or awaiting a kidney transplant and for whom vascular access patency is vital. Due to their traumatic effect on the vessel wall, these procedures induce cell proliferation processes that retrigger neointimal hyperplasia the very act of preserving the haemodialysis access is the key factor in development of a new stenosis and hence a vicious circle of stenosis-angioplasty. For the past few years, angioplasty balloons delivering anticancer drugs have been developed. These drugs, generally used in high doses for cancer chemotherapy, are released in small doses on the medical angioplasty devices. During inflation, the local release of the anticancer molecule through the different layers of the vessel wall confers local antiproliferative action without the systemic toxic effects associated with high-dose chemotherapy. These medical devices have demonstrated their efficacy in terms of increase in primary and secondary patency rates on procedures such as coronary artery angioplasty, femoro-popliteal or sub-popliteal artery angioplasty. These drug-eluting balloons (DEBs) are also CE marked with the recommendation of being indicated for AVF anticancerangioplasties, but no randomised multi-centre clinical trial has proven their medical effectiveness, and in particular their contribution in terms of patency rate improvement. However, studies on animal models show significant results regarding efficacy against neointimal hyperplasia and the first single-centre clinical trials on a small sample size appear promising. The key assessment criterion is primary patency of the dilated stenosis at one year defined by patients efficaciously dialysed at one year without re-intervention on the dilated lesion after initial angioplasty. The delay of occurrence of dilation will be considered. Patients that will be non-evaluable for the primary endpointwill be censored at the date of the latest news.
This study is designed to assess the effectiveness of porcine cross-linked collagen paste for the treatment of patients with ano-rectal abscess with underlying cryptoglandular fistula in ano.
This is a randomised controlled trial to evaluate the outcome of treatment of complex perianal fistula by Video-assisted anal fistula treatment (VAAFT) compared to fistulectomy and sphincter reconstruction as standard surgical procedure.
This study will investigate if liposomal prednisolone is effective in promoting arteriovenous fistula (AVF) maturation when administered to human subjects after surgical creation of a radio-cephalic AVF.
This clinical trial will evaluate the safety and efficacy of the Strattice-LIFT procedure to treat anal fistulas.
This study is designed to compare the safety and efficacy of paclitaxel-eluting balloon (DEB) versus conventional percutaneous transluminal angioplasty (PTA) for the treatment of hemodynamically significant recurrent cephalic arch stenosis in brachial cephalic fistulas in hemodialysis patients.
This is the 5th in a series of physiological studies to determine the amino acid requirements of infants. There have been 4 studies to determine tyrosine, methionine, threonine and lysine requirements in infants when they are fed by parenterally (intravenously). Due to the new requirements of Health Canada for preparation of parenteral solutions, the investigators are starting the phase of the study that determines the enteral (oral) intake of threonine in 1 - 6 mo infants in the interim.
