It is clear from multiple accounts in the literature that patients with a vesico-vaginal fistula (VVF) involving the bladder neck and/or proximal urethra have a high likelihood of residual incontinence. Performing subsequent surgeries after the initial VVF repair risks additional complications. Therefore, placement of an autologous sling at the time of initial VVF repair would not only assist in covering the fistula, but would also imitate the physiologic support that would theoretically improve urethral function. A rectus fascia sling would most naturally provide this support and warrants testing against the success of the PC sling. Using the Goh scoring criteria, Goh class 3 and 4 VVF's are the type most involving the urethra. Therefore, this group of patients is the target population for this study. As there is currently no standard of care for repairing large urethral defects, this procedural technique combined with otherwise standardized fistula repair would not introduce any foreseeable harm to patients.
The main purpose of this study is to compare the Human Acellular Vessel (HAV) with arteriovenous fistula (AVF) when used for hemodialysis access
This is a prospective randomized multi-center non-inferiority trial conducted through the Pediatric Regional Anesthesia Network study sites to determine if caudal block increases the incidence of urethrocutaneous fistula following distal or mid shaft hypospadias repair compared with penile nerve block.
The aim of this phase 1 study is to determine the role of autologous adipose derived mesenchymal stem cells in the reduction of hemodialysis arteriovenous fistula failure when applied during the time of surgical creation.
Pancreatic resections carry a high risk for complications, especially pancreatic fistula. Both hydrocortisone and pasireotide have been shown to be effective in reducing complications in earlier RCTs. The aim of this study is to compare the effectiveness and safety of these two drugs in preventing complications of pancreatic surgery.
The purpose of this study is to determine whether anal fistula plug or endorectal advancement flap is more successful in the treatment of anal fistulas and compared both procedures with regards to cost.
Dialysis access, which is the connection that allows blood to flow in and out of the body during dialysis sessions, is important to remove wastes and excess fluid for patients with end stage renal disease (ESRD). One method used to access the vein and artery for dialysis is called a brachiocephalic fistula. Patients are being asked to participate in this study because they have endstage renal disease, and their doctor has recommended that they will have brachiocephalic fistula placed for their dialysis access. A common problem seen in patients with a brachiocephalic fistula (BCF) is cephalic arch stenosis (CAS). CAS is a narrowing in the central vein (located in the upper chest). CAS causes problems with the opening of the veins and arteries needed for dialysis. Once someone suffers CAS they may need several radiology procedures as well as surgery to help correct the problem. The BCF may fail once CAS develops. The purpose of the research study is to gather information about the BCF and what is happening inside the vein. The researchers hope to find out what may be the cause of CAS.
This study is to assess whether utilizing endoscopic ultrasound(EUS) to guide treatment can improve durable fistula healing in patients with Crohn's perianal fistulas and to get preliminary information regarding the effectiveness of Adalimumab for Crohn's perianal fistulas.
This comparative, multicentre, randomised clinical trial is designed with two parallel groups that will follow a treatment either with an autologous implant of ASCs (Adipose Derived Stem Cells) and fibrin glue (tissue adhesive material) or with fibrin glue alone for the non-surgical treatment of complex perianal fistula.
