Active clinical trials for "Fistula"

This procedure allows patients to use the Humanitarian Use Device, IBV® Valve System.

Arteriovenous fisutla (AVF) is the vascular access of choice for hemodialysis but has a high early failure (eAVFF) rate. eAVFF can be defined as thrombosis/stenosis and Doppler ultrasound (DUS)-based failure-to-mature parameters such as postoperative blood flow (PostQa) < 500 ml/min, AVF-vein diameter (PostVD) < 5 mm, and AVF-vein depth (PostVDepth) ≥ 6 mm. We explored whether common risk factors for eAVFF could predict these eAVFF parameters and venous distensibility: the latter is largely overlooked as a potential eAVFF parameter.

Evaluation of the incidence of palatal fistula in Furlow double-opposing z-plasty versus two-flap palatoplasty for cleft palate repair.

It is clear from multiple accounts in the literature that patients with a vesico-vaginal fistula (VVF) involving the bladder neck and/or proximal urethra have a high likelihood of residual incontinence. Performing subsequent surgeries after the initial VVF repair risks additional complications. Therefore, placement of an autologous sling at the time of initial VVF repair would not only assist in covering the fistula, but would also imitate the physiologic support that would theoretically improve urethral function. A rectus fascia sling would most naturally provide this support and warrants testing against the success of the PC sling. Using the Goh scoring criteria, Goh class 3 and 4 VVF's are the type most involving the urethra. Therefore, this group of patients is the target population for this study. As there is currently no standard of care for repairing large urethral defects, this procedural technique combined with otherwise standardized fistula repair would not introduce any foreseeable harm to patients.

Radionuclide cisternography (RC) is a nuclear medicine examination based on intrathecal injection of [111In]diethylenetriaminepentaacetic acid ([111In]DTPA). It is prescribed for two recommendations: detection of cerebrospinal fluid (CSF) leak/fistula and diagnosis of normal pressure hydrocephalus. In the search part of CSF leak/fistula, RC offers the benefit of a 24-hour study of CSF unlike other reference tests. In addition to SPECT/CT imaging, the radiopharmacist performs sampling in nasal cavities and throat of the patient to collect a possible flow of CSF. These samples are analysed by radioactivity measurements and bring an added value to the exam. The interest of this examination for management of CSF leak/fistula remains unclear. The aim of this study is to identify and analyse results of all RC examinations performed since 2005 in the Nuclear Medicine department of the Neurological Hospital. The full analysis of patients will allow discussing the role of RC in management of CSF leak/fistulae in clinical practice.

Arteriovenous fistulae are preferred among methods of providing blood access for hemodialysis. For each hemodialysis treatment, the fistula is cannulated usually with two needles. One, the arterial needle, allows the blood to be withdrawn from the patient into the dialysis circuit and then it is returned by the second or venous needle. The success of arteriovenous fistula cannulation is dependent on many variables and these are affect the dialysis adequacy.

Liver transplantation enhances the prognosis of patients with cirrhoses or hepatocellular carcinoma. However some patients develop intestinal perforations for which the prognosis is poor. The aim of the study is to evaluate the risk factors of intestinal perforations using a retrospective study scheme.

Children with esophageal atresia and tracheoesophageal fistula (EA-TEF) may experience feeding and swallowing difficulties, which result in stressful interactions between children and caregivers, and potentially impact the concerns of caregivers. The aim of this study was to assess concerns of caregivers of children with EA-TEF related to feeding-swallowing difficulties.

The purpose of this study is to gain a better understanding of the disease burden and unmet need of perianal fistulas within Crohn's disease (CD) in Ontario.

Brief Summary:* Aim of the study : To evaluate if the neck division level significantly influences the postoperative pancreatic fistula rate of pancreatico-jejunal anastomosis after pancreatoduodenectomy. Methods : Patients who underwent oncologic or non-oncologic pancreatoduodenectomy between 01 January 2009 and 04 April 2018 will be included in this retrospective analysis. Two independent radiologists will measure the distance between the left side of the portal vein and the remnant pancreatic stump on post operative CT scan, blindly for postoperative course. This new variable will be integrated in a logistic regression model in addition to well known risk factors of POPF.
