Active clinical trials for "Fistula"

Purpose : The primary goals of this study were to determine the prevalence and risk factors of occult CBC and recurrence, as well as the relationship between occult cysto-biliary communications manifested as postoperative biliary leakage and recurrence. The secondary goal was to use chemical analysis of hydatid cyst fluid to assess excessive bilirubin and alkaline phosphatase levels as predictors of fistula and recurrence. Methods: This prospective multi-center experimental and follow-up study of six years duration was conducted at the hepato-biliary pancreatic units of our universities hospitals from September 2010 to September 2016. Initially, 292 patients were included, but only 244 patients enrolled in the final study.

A prospective, multi-center, randomized (1:1) clinical study evaluating the FLEX Vessel Prep device plus percutaneous angioplasty (PTA) (study arm) vs PTA alone (control arm) for the treatment of obstructive lesions in the native arteriovenous dialysis fistulae.

Pulmonary vein isolation emerged as an effective and safe strategy to treat atrial fibrillation patients. Atrio-oesophageal fistula (AOF) represents a rare but devastating complication of AF ablation procedure. This complication (0.016-0.07%) requires an international effort to allow for better understanding of the factors contributing to its occurrence and the best management strategies. A worldwide, retrospective, multicenter registry focusing on the incidence, diagnosis and management of this complication.

This prospective randomized controlled clinical trial included all patients who developed the manifestations of low output recurrent colonic fistula or leak after colonic anterior resection for rectal cancer at Zagazig University hospital between (December 2020 to August 2022). The study was prospectively approved by Zagazig University Faculty of Medicine Institutional Review Board (Approval Number: 10027/26-10-2022) .The investigators performed the study under the code of ethics of the World Medical Association (Declaration of Helsinki) for studies involving human subjects. They got written informed consent from all participants after explaining to them all the study procedures with its benefits and hazards. Patients with recurrent low output colo-cutaneous fistula (less than 500cc/24h) or leak after anterior resection due to rectal cancer , patients who subjected to conservative measures but failed , patient with good general condition (ASA I&II), patients with size of fistula less than 15mm and patients with good nutritional status were included and eligible for randomization. The investigators excluded patients who were with bad general condition (ASAIII&IV&V), patients with high output fistula , patients with recto-vaginal or recto-vesical fistula, patients with size of fistula more than 15mm and patients were treated with conservative measures. Included eligible patients were simply randomized at a 1:1 ratio to "Endoscopic (SG)" or "Surgical Group (EG)" via the drawing of sealed envelopes containing computer-generated random numbers prepared by a third party before the start of the intervention.

This study evaluates the effect of hypertonic saline 23.4% injection in fistulas or sinus tracts in adult patients with hidradenitis suppurativa.

A multicenter randomized clinical trial of paclitaxel drug-eluting balloon (DEB) versus standard percutaneous transluminal angioplasty (PTA) to reduce restenosis in 150 patients with haemodialysis access stenoses.

In recent years the use of paclitaxel releasing percutaneous transluminal angioplastic (PTA) balloon catheter is spreading in vascular pathology, mainly in stenosis infrainguinal arteries. This device combined the mechanical action of PTA balloon with the antiproliferative effects of paclitaxel. The use of these devices in venous pathology is limited. This devices could improve the treatment of renal dialysis arteriovenous fistula stenosis.

Crohn's disease is a chronic inflammation of all or part of the digestive tract, " from the mouth to the anus ". . Cell therapy is a new and promising approach for the treatment of inflammatory disease including Crohn's disease and fistulas. Adipose tissue seems to be an ideal source for cell therapy. This is a prospective, open, non-comparative, single center, phase I-II clinical trial. It will involve 10 patients and will be conducted over a period of 28 month. This protocol is designed to evaluate, in patients with Crohn's disease and fistula-in-ano refractory to conventional medical and surgical treatment, the safety and efficacy of local microinjection of autologous adipose tissue and SVF from microaspirate . The main objective is to assess tolerance and security. The secondary objective is to evaluate the effectiveness of this technique

Different studies suggest that early enteral nutrition (EEN) has benefits in reducing infectious complications, there is no data that addresses whether delayed enteral nutrition (EN) is detrimental and if it may have effects on inflammatory responses and immune function.

The aim of this study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) on patient suffering from residual Crohn's disease related perianal fistulas already treated with TNF alpha blockers
