Active clinical trials for "Fistula"

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.

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 One, the arterial needle, allows the blood to be withdrawn from the patient into the dialysis circuit and then it is returned by the second or venous needle.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.

Prostate cancer is the first cancer amongst men with more than 50000 cases per year in France. Surgical, radiation, frost, or ultrasound induced rectourethral fistula is a rare complication (<1%) of localized prostatic cancer treatment but hard to manage. Different types of treatment exist: conservatory, trans-sphinteric (York-Masson), transanal, perineal, with or without muscle flap interposition. Gracilis flap interposition for rectourethral fistula management is a promising technique but few cases are described and functional results are scarce. The aim of this study is to present surgical and functional outcomes of rectourethral fistulas surgery with gracilis flap interposition after treatment of localized prostate cancer.

This study investigated the impact of highest drain fluid amylase (DFA) level on postoperative pancreatic fistula (POPF) severity and outcomes of patients undergoing pancreaticoduodenectomy (PD) with POPF. Patient demographics of biochemical POPF and clinically relevant POPF (CR-POPF) were compared. Predictive factors were assessed using binary logistic regression. Receiver operating characteristic curve analysis was performed to determine the optimal cutoff value of highest DFA (beyond 3 days post-PD). The investigators compared length of hospital stay, surgical mortality rates, and need for postoperative interventions by highest DFA level.

For non-healing ulcers, abnormal periods of wound healing processes: inflammation, proliferation and remodelling, are believed to lead to chronic wounds. As a chronic "stalled" wound, investigators hypothesized that these glue-assisted closure (GAC)-failed enterocutaneous fistula (ECF) might have a prolonged inflammatory phase modulated by excessive pro-inflammatory cytokines or proteases. The aim of this study was to analyze the chemicals in ECF wounds in order to determine patients' condition and fitness for GAC.

Patients whose kidneys have failed need to receive dialysis treatment, most commonly with a dialysis machine. In order to be connected to the machine an operation is often performed to join an artery to a vein in the arm. This forms what is known as an arteriovenous fistula. The fistula causes an increase in the flow of blood through the vein and the vein reacts to this by becoming bigger and thicker, making it easier to connect the patient to the machine. The success rate for the operation is relatively low and only approximately 65 from every 100 operations is still working after a year. It is thought that one factor that may cause problems with the fistula is the ability of the vein to stretch in response to increased blood flow. Previous research has shown that veins in kidney failure patients look different to those of people whose kidneys are working when viewed under a microscope. The investigators aim to study the structure of the vein that is used in making fistulas with a microscope and also to test it in an engineering laboratory to see how much it will stretch. The investigators hope that gaining information about the structure of the vein and its ability to stretch will help determine what it is about the vein that affects how well it works as part of a fistula. This information may help surgeons select the best possible vein in a given patient to give the best chance of a working fistula in the future.

This project will bank sera, DNA and vascular specimens from patients undergoing arteriovenous fistula creation and revision.

The purpose of this trial is to determine whether the use of an autologous falciform ligament patch combined with fibrin glue will reduce the rate of pancreatic fistula in patients completing distal pancreatectomy. The hypothesis for the current trial is: Autologous falciform patch closure with fibrin glue will result in a 50% decrease in fistula formation postoperatively. The primary end point will be the development of pancreatic fistula using the ISGPF definition of pancreatic fistula1. (Drain output of any measurable volume of fluid on or after postop day #3 with an amylase content greater than three times serum amylase). Secondary end points will include length of postoperative hospital stay, percutaneous intervention rates, re-operation rates, morbidity to include delayed gastric emptying, wound infection, intraabdominal abscess, postoperative hemorrhage and 30-day mortality.(Bassi C, Dervenis C, Butturini G, et al. Postoperative pancreatic fistula: An international study group (ISGPF) definition. The Journal of Surgery, 2005;138:8-13).

This study is a prospective evaluation of quality-of-life after rectovaginal fistula repair at our institution

Postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy is considered a life-threatening complication. This study was designed to analyze the risk factors for development of such fistula in a tertiary care center (Al-Rajhi Liver Hospital/ Assiut University).
