Active clinical trials for "Fistula"

The International Study Group of Pancreatic Surgery (ISGPS) issued the definition and classification system of postoperative pancreatic fistula (POPF), and received widespread recognition. Currently, it has become an important reference for clinical treatment of POPF.

This study is designed to identify novel predictors of vascular access success or failure in chronic kidney disease patients. Despite efforts to improve placement of arteriovenous fistula (AVF) the primary failure rates are reported as high as 20-50%, but standard tools like ultrasound cannot inform the clinician sufficiently to accurately predict success or failure. The aim of this study is to perform enhanced assessments of arterial health preoperatively and correlate these measurements with vascular lesions (microscopic tissue changes and monocyte infiltration) and early AVF outcome. Activation of monocytes in uremia condition is responsible for endothelium dysfunction, intimal hyperplasia and atherosclerosis. The investigators expect that stiff arteries caused by monocyte dysfunction refer to the poor distensability and probably longer maturation time.

This is a pro- and retrospective cohort study to evaluate the natural history and outcome of various treatment options of patients with fistula. At each clinical visit parameters describing activity of a fistula, potential underlying Crohn's disease, investigations as well as the current treatment will be entered into a database. Selected patients can also be contacted by phone in the form of a structured interview. Data will be analyzed to determine treatment outcomes, characterize the natural history as well as risk factors for complications of treatment and an unfavorable disease course. The same data will be obtained and analyzed retrospectively from patients who visited the clinic prior to January 2017.

The transplant is the definitive treatment of renal insufficiency, in our days. While waiting for it, the arteriovenous fistula surgery is standard procedure.

The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis(HD), and fistula-first is the general recommendation for all HD patients. But in clinical practice in China, quite a few patients start HD before AVF maturation due to various situations. Whether HD initiation with mature AVF will influence the patency and complications is controversial. This study is aim to compare the AVF patency in incident HD patients with mature or immature AVF on HD initiation, and to compare other clinical outcomes, including abandonment without use, infection, and other AVF complications occurrence.

Distal pancreatectomy is the surgical technique performed to treat many pancreatic diseases located in neck and tail of the pancreas. Laparoscopic approach is the gold standard but in many centres the percentage of laparoscopic approach is still low. This technique has low mortality but 30% morbidity mostly related to pancreatic fistula. Some new devices (linear stapler, energy devices and patches) seem to decrease pancreatic fistula but there is not evidence based medicine that confirm the results published usually in unicentric studies.

Robot-assisted Vesico-Vaginal fistula (VVF) repair was described a few years ago as an alternative to the open approach to minimize the morbidity of this surgery. Very little series have reported the results of robotic VVF repair. The objective of this work was to evaluate the results of robotic VVF repair.

The investigators recently proposed a new hypothesis on the pathogenesis of mammillary fistulae (MF) suggesting that occlusion of hair follicles by keratinous plugging may relevantly contribute to the development of MF. The investigators believe that the pathogenesis of MF mimics the behaviour of hidradenitis suppurative, as both clinical entities manifest themselves as a chronic, suppurative and recurrent inflammatory process. This new proposal has led to the present suggestion of a therapeutic alternative for MF.

Pancreatic fistula (PF) grade C, defined by the International Study Group of Pancreatic Fistula (ISGPF) is associated with a life-threatening complication after pancreaticoduodenectomy(PD). Therefore, The aim of this study is to clarify the risk factors for grade C PF by Japan and Taiwan cooperative project.

New produced and patented sodium pantaborat based gel will be use for treatment of benign perianal diseases (hemooroidal disease, anal fissura anda perianal fistula)
