Active clinical trials for "Fistula"

There is still no consensus on whether drain fluid amylase (DFA) level, C-reactive protein (CRP) level, or complex scores predict clinically relevant postoperative pancreatic fistula (CR-POPF). The aim of this study is to determine the accuracy of simple biochemical parameters (leucocytes, neutrophils, lymphocytes, Neutrophil to Lymphocytes Ratio (NLR), at postoperative days 1 and 3) to exclude the diagnosis of CR-POPF.

Anal fistula is a common condition with a wide variety of clinical presentations, which can make evaluation and treatment challenging and surgical outcomes uncertain. This study was undertaken to identify lessons learned in the surgical treatment of 483 patients over a 20- year period leading to a pragmatic approach to treatment of this condition.

The occurrence of post-pancreatectomy acute pancreatitis (PPAP) can critically impact outcomes after pancreaticoduodenectomy. Although diagnosing a PPAP can be challenging, its identification appears crucial as it can trigger additional morbidity. However, due to the early onset in the perioperative period, the actual spectrum of its early phases has not been systematically explored yet. For this reason, the present study will compare some early biochemical evidence of pancreatic stump damage to morphological changes evident at postoperative imaging. The postoperative evaluation of serum and/or urine pancreatic enzymes and the radiologic assessment are included in everyday clinical practice. However, the timing and the clinical relevance of such findings mostly rely on the single-institution experience. This study aims to characterize PPAP by investigating its early radiologic, biochemical, and clinical spectrum of either local or systemic changes associated.

Preoperative vascular mapping with echo-Doppler is acknowledged as indispensable to create an arteriovenous fistula for haemodialysis (AVF). The conditions for performing this examination are not always ideal (venous vasospasm in cool temperatures, variability of the volume status in the dialysis patient). On the other hand, the use of a loco-regional anaesthesia (LRA) results in the vasodilation of the limb thus rendering it possible to use the veins which were initially considered too small. The aim of this study is to assess the functionality of our AVF when ultrasound identification was used by the surgeon after the LRA. These results have been compared with those of the preceding year during which this identification was not implemented.

The objective of this proposal is to create a database for obstetric fistula patients at Bwaila Hospital containing their demographics, obstetric history, fistula history, physical exam findings, intraoperative and postoperative results. Data collection will be prospective starting in 2011 upon institutional review board (IRB) approval to last a minimum of five years and will have a retrospective component tracing back to January 2010. Primary goals of data analysis will be to determine the risk factors for fistula formation, risk factors for poor surgical outcomes and long-term incontinence, social and economic impact of fistula repair, and the ability of various physical exam findings to predict likelihood of successful repair. It is expected that findings will lead to improved surgical management of obstetric fistulas both locally and internationally.

The purpose of this study is to describe the long-term surgical success, quality of life, prevalence of depression, fertility rates, and pregnancy outcomes of patients who have undergone obstetric fistula repair. This will be a study involving up to 300 women 1-3 years after they have undergone obstetric fistula repair at the Fistula Care Center in Lilongwe, Malawi. Patients who underwent obstetric fistula repair between January 1, 2012 and July 31, 2014 will be identified from an existing database of fistula patients. They will then be contacted and invited to participate in the study. Consented patients will complete a 1-hour pad weight to evaluate urinary continence, a demographic questionnaire, an incontinence-related quality of life metric, and a depression metric. The data will be analyzed and then disseminated to stakeholders.

An arterio-venous fistula is a surgical procedure that supports access for people undergoing hemodialysis (HD) for End Stage Renal Disease (ESRD). This observational pilot study seeks to better understand the factors that contribute to the successful maturation of an arterio-venous fistula. A primary aim of this study is to see if endothelial function (the biochemical events initiated by cells lining the arteries) is associated with successful maturation. Other aims include determining if pro-inflammatory markers in the blood or evidence of gene expression are associated with successful maturation.

Our study seeks to define the effect of each component of the distal revascularization interval ligation (DRIL) procedure on the in vivo distal blood pressure of patients with ischemic steal, and to determine whether the interval ligation component of the DRIL procedure is necessary or not.

This study will compare healing and surgical outcomes in patients with chronic perianal disease treated with Adipose-derived Stem Cells (ASCs) to outcomes in patients treated in traditional surgical techniques without ASCs. The study will perform retrospective medical record analysis to clinically characterize patients that have undergone these surgical procedures and compare follow-up data and disease status to determine efficacy of treatment with ASCs compared to similar treatments without the use of ASCs. This will help determine overall efficacy of the treatment as well as determine patient characteristics that may predict treatment success. The study will also prospectively recruit patients with perianal disease that are planning to receive treatment with ASCs, and analyze their outcomes in the same way. Medical record review of outcomes in patients with perianal disease that received treatment with ASCs compared to those that did not will determine efficacy of this procedure.

The study aims to evaluate the efficacy of the local injection of autologous micro-fragmented adipose tissue obtained with the Lipogems®system in patients with trans-sphincteric fistulas untreatable with fistulotomy.
