Active clinical trials for "Fistula"

Randomized controlled study to compare the results of two surgical techniques for AVF creation, including the anchor technique (Group A) and parachute technique (Group B). The study population will be patients referred to the Vascular surgery department for the creation of Hemodialysis access. Patients will be advised to undergo elective surgery for AVF once their renal Glomerular Filtration Rate Estimated (eGFR) is less than 15 ml/min. primary outcome: Functional Maturation of Arterio-venous Fistula [ Time Frame: Six Months] Ready fistula for cannulation, vein length at least 10 cm, diameter more than 6 mm, depth not more than 6 mm, and ability of the access to deliver a flow rate of 600ml/min and maintain dialysis for 4 hours.

A laryngectomy involves removing the voice box from the throat. After the voice box has been removed from the throat, the surgeon sews the throat closed. Sometimes part of the throat does not heal and saliva runs out of the throat. This is called a fistula. When a fistula happens, healing takes longer and patients will have to wait to eat and start speaking. The test in this research project is called ICG scan (indocyanine green) and tells the surgeon how much blood is flowing to different parts of the throat. If the test shows that there are parts of your throat that have low blood flow, which will delay healing. Only half of the patients in the study will get the ICG scan. This is so the patients who had the ICG scan can be compared to the patients that did not have the ICG scan to determine if the ICG scan really helps decrease fistulas.

The purpose of the study is to compare the clinical outcomes of two commonly used, FDA-approved biologic meshes in hernia repair and abdominal wall reconstruction (Strattice and XenMatrix). The two meshes are derived from pig skin from which cells have been removed and which have been sterilized. The two meshes are made by two different companies using different processes.

Atrial fibrillation (AF) is a common debilitating heart rhythm condition that can cause heart failure and negatively impact a patient's outlook in terms of symptoms and disability. It is an irregular fast heart rhythm disorder coming from the top chamber of the heart (left atrium). Catheter ablation treatment has been shown to be effective in controlling or eliminating AF and its associated symptoms. This is now a common and effective treatment option for patients suffering with AF. During ablation, thermal energy is applied in the top chamber of the heart (the left atrium) to abolish abnormal electrical signals that cause AF. It is generally a safe procedure, but one potential risk associated with this procedure is damage to the oesophagus caused by thermal energy being transmitted to the oesophagus from the heart. The oesophagus sits just behind the heart chamber where ablation work is performed, about 5mm away, so it is vulnerable to damage. Although the risk of severe oesophageal damage is low, if it occurs it can be serious as the patient may become very ill as a result. In a recent study, it was shown that a more advanced type of oesophageal probe that cools the oesophagus during ablation is better at protecting the oesophagus from ablation-related injury compared to the standard care probe currently used. As it was a single-centre study, more evidence is required before knowing if this type of probe is more effective in protecting the oesophagus. The purpose is to run a multi-centre randomized study to compare the safety of AF ablation when there is protection by the oesophageal cooling probe versus the standard of care oesophageal temperature monitoring probe. This means that there is a 50:50 chance of the new cooling probe being used during AF ablation for participants.

The FIBROPANC-1 investigates the feasibility and safety of preoperative stereotactic radiotherapy of 4cm pancreas in patients undergoing pancreatoduodenectomy at high risk (>25%) of developing post operative pancreatic fistula (POPF). A single course of 12Gy preoperative radiotherapy may lead to sufficient fibrosis in a small (4cm) targeted area, thereby reducing the risk of grade B and C POPF.

This is a phase III study to evaluate the efficacy and safety of ASC(Autologous Adipose-derived Stem Cells) and Fibringlue or Fibringlue in Patients With Crohn's Fistula.

The number of hemodialysis patients in the world are increasing. In order to receive a sufficient dialysis, the patients needs a well functioning and stable vascular access - preferably an arteriovenous fistula (AVF). Unfortunately, the AVF has a high incidence of stenosis with percutaneous trans luminal angioplasty (PTA) as the only treatment option and a short lifetime. Little do we know of how to improve the survival of the AVF. With this study we want to explore the effect of far infrared therapy on the stenosis, maturation and survival of the arteriovenous fistula. The investigators will divide the patients into 2 groups: A treatment group and a control group. The treatment group will receive infrared therapy on their fistula during their dialysis session. The control group will not receive any infrared therapy. The investigators hope to reduce the risk of stenosis in the fistula and improve the fistula survival with this treatment. Furthermore, the investigators want to explore the change in several biochemical markers during the treatment with infrared therapy.

The aim of this study is to evaluate both clinically and radiologically the efficacy of using the pedicled buccal periosteal flap for closure of oroantral fistula without affecting the original intraoral anatomy.

Postoperative pancreatic fistula (POPF) is the main driver of surgical morbidity after pancreatoduodenectomy (PD). The aim of the present study is to compare total pancretectomy (TP) and primary pancreatic anastomosis (PA) in a cohort of extremely high-risk patients, with regards to postoperative outcomes and quality of life (QoL).

The aim of this randomized controlled study is to compare the efficacy of biodegradable internal pancreatic stenting versus no stenting in patients undergoing pancreatoduodenectomy (PD), focusing on a possible superiority association of the device in preventing clinically relevant postoperative pancreatic fistula (CR-POPF). Patients undergoing PD will be randomized into two arms: arm 1: a biodegradable internal pancreatic stent will be placed at the level of the pancreatic anastomosis arm 2: no pancreatic stent will be placed at the level of the pancreatic anastomosis The rate of occurrence of CR-POPF will be compared between the two arms.
