Active clinical trials for "Fistula"

This is a pilot randomised controlled trial comparing open versus thoracoscopic surgery for repair of oesophageal atresia with tracheo-oesophageal fistula or congenital diaphragmatic hernia in neonates. Thoracoscopic surgery involves insufflation of carbon dioxide into the thoracic cavity and may therefore cause hypercapnia and acidosis.

The purpose of this study is to determine if the collagen plug method heals perirectal fistulae as well as the conventional seton method.

The Objectives of this study are: To determine if vorapaxar safely improves arteriovenous (AV) fistula functional maturation when administered during the maturation process compared with placebo. To determine if vorapaxar safely improves AV fistula patency, allowing for secondary procedures to aid in fistula maturation compared with placebo. To determine if vorapaxar safely facilitates successful cannulation of AV fistulas for hemodialysis compared with placebo. This is a randomized placebo-controlled double-blind pilot trial. Study procedures will be conducted at Stanford University Medical Center, and standard-of-care (SOC) procedures will be conducted at Stanford and it's affiliated hospitals (Veteran's Affairs Palo Alto Health Care System and the Stanford Vascular Surgery Clinic at Valley Medical Center). The investigators expect to enroll 128 patients. Patients will be assigned to treatment groups with a 1:1 randomization in blocks of 4 at the conclusion of the AV fistula creation. Patients will be stratified based on fistula location (lower arm versus upper arm).

Pancreaticoduodenectomy is a surgical procedure for removing cancer in the pancreas, the bile system or the duodenum that is associated with a high rate of complications. The study wants to investigate whether a new technique to reconstruct the joint between the pancreatic gland and the short bowel can reduce the rate of severe complications after this complex surgical procedure.

Arteriovenous fistula is the preferred access for hemodialysis, and cannulation using a "button-hole" technique is increasingly recommended. By using the same two sites for cannulation there are reports of less risk of complications and less pain for the patient. However, button-hole cannulation can be difficult for the dialysis nurse, and failing cannulations can damage the AV fistula and increase patient discomfort. The investigators therefore will test whether a simple marking on the skin of the direction and angle of cannulation used in each specific patient could improve the probability of a successful and painfree cannulation.

The purpose of this investigation is to carry out a clinical evaluation of a newly developed fistula pouching system's ability to function as a good pouch for fistulas, with the opening on the skin of the stomach or in a wound on the skin of the stomach.

The objective of this pilot study is to evaluate the feasibility, safety and efficacy of 3M™ Cavilon™ Advanced Skin Protectant when used in the management of damaged skin exposed to caustic body fluids from an ostomy, drain site or fistula.

This project will examine if enhancing Nitric Oxide (NO) bioavailability increases the rates of arteriovenous fistula (AVF) maturation in end stage renal disease patients requiring vascular access for hemodialysis. To enhance NO bioavailability the study team will utilize a program of forearm exercise training, application of nitroglycerin ointment or both. Goals of this study are (A) to measure if recruited subjects can tolerate the intervention protocols, and determine if dependent variable measures, including surgery outcome, and measurement of physiologic and biologic markers, can be obtained; (B) To measure subject compliance and adherence rates for each of the intervention arms and testing visits; (C) To examine which intervention or combination of interventions demonstrates the strongest preliminary effects in order to estimate power for a pivotal intent to treat trial; and (D) explore group differences in clinical vascular markers and biologic markers in vein tissue.

Esophageal stents are commonly used for benign esophageal pathology, especially strictures or esophageal mucosal defects such as leaks, fistulae, or perforations. The major limiting factor to stent placement is the high migration rate of the stent. Investigators are trying to prospectively evaluate the efficacy of endostitch in preventing stent migration in benign esophageal disease in comparison with standard, fully covered self-expanding metal stents (FCSEMS) placement without fixation.

Post-operative pancreatic fistula (POPF) after pancreatic resection is a potentially life-threatening complication occuring in up to 27% of patients undergoing a pancreatic resection. Despite several strategies have been proposed further improvements are needed. Many studies suggest that amniotic membrane(AM) implantation is effective in tissue regeneration and prevention of fluid leakage at many surgical sites. However,the implantation of AM has never been used in pancreatic surgery. After having completed the first case of implantation of AM we proceed with this pilot study to determine in 20 consecutive patients undergone to pancreaticoduodenectomy (PD) with high risk of POPF, the efficacy of AM in reducing this event and the related morbidity.
