Filter by:Dialysis patients have their blood filtered by a machine as their kidneys no longer work. To get blood in and out of these patients it is possible to perform a surgical procedure to increase to size and durability of a vein in the arm to allow repeated needle insertion. This enlarged vein is called a fistula. There is some evidence that ultrasound scanning the blood vessels in the arm before surgery can improve the chances of a successful procedure. The investigators aim to test whether scanning all patients is better than scanning only those who are difficult to assess by physical examination alone.
The purpose of this study is to determine safety and efficacy of allogenic eASCs (expanded adult stem cells) for the treatment of recto-vaginal fistula in patients with Crohn´s disease.
Up to date, a sure cure for Crohn's fistula has not known and the fistula recurrence rate is high. On 15 October 2008, orphan drug designation was granted by Korea FDA to Anterogen Co. Ltd., for human adipose-derived stem cell. In this study, patients are given injection of ADIPOPLUS in fistula site and followed for 8 weeks to test the safety and efficacy.
The purpose of this study is to determine whether human acellular dermal matrix plug is effective in the treatment of anal fistula
Surgical treatment of perianal fistulas frequently affects fecal continence. Sphincter saving techniques like loose or cutting seton and fistulectomy with advancement of an endorectal flap have been advocated to minimize the risk of sphincter injury, but patients often complain of a prolonged healing period and major discomfort. Furthermore, the healing rate varies widely according to the type of fistula and the surgeon's experience.In the early '90s the treatment of perianal fistulas by autologous or commercial fibrin glue was suggested and the American FDA approved the use and marketing of a human fibrin glue in 1998. Since then, several studies have evaluated the effectiveness of human fibrin glue in the treatment of different types of perianal fistulas, reporting a wide range of success rates ranging from 31 to 85%. Primary aim of this study is to conduct a prospective randomized trial evaluating the effectiveness of glue treatment of perianal fistulas as compared with the classical seton treatment. Secondary aims are to compare postoperative faecal incontinence, postoperative anal pain, healing time and length of hospitalization.
This clinical trial will study the safety and effectiveness of the Biodesign Vesico-vaginal fistula plug in the treatment of vesico-vaginal fistulas resulting from childbirth trauma.
Evaluate access to healthcare, comprehension of pre-operative counseling and post-operative goals of women treated for vesicovaginal fistula in Niger through use of a questionnaire.
This project will bank sera, DNA and vascular specimens from patients undergoing arteriovenous fistula creation and revision.
Background: T-shaped tissue anchors have promise to close incisions and perforations of the intestines securely. The closure of perforations, gastro-gastric, or intestinal fistulas usually requires invasive open or laparoscopic surgery under general anesthesia and can be complex surgeries due to their reoperative or inflammatory nature. Objective: The proposed use of full thickness tissue anchors adds a new surgical aspect to the endoscopic treatment of fistulas and perforations by offering a robust suture like closure of defects. Instead of a 20 cm abdominal incision or 3 or 4 one centimeter incisions with the related postoperative morbidity an endoscopic technique is used which requires no postoperative limitation of activities. Methods: In this study the investigators propose to use an endoscopic technique that eliminates the need for open or laparoscopic surgery and provides a more robust endoscopic repair than is possible with traditional endoscopic tools. Patients who are scheduled to undergo surgery for intestinal fistulas will be screened for study eligibility. Patients who are scheduled to undergo complex polypectomy, or submucosal dissection will be screened for study eligibility and informed about all possible therapies in case of an iatrogenic perforation (open - laparoscopic surgery, endoscopic clipping, endoscopic closure with tissue anchors). A commercially available flexible endoscope will be inserted through the mouth and the fistula or perforation will be closed using the Tissue Approximation System (Ethicon Endo Surgery, Cincinnati, OH). The investigators will initially evaluate the potential benefit, risks and impact on the patient's quality of life of this modified surgical technique in 5 patients. Expected results: The potential advantages to the patients entered into this study result from the avoidance of open or laparoscopic surgery with the related risks (bleeding, injury of organs, post operative wound infection, hernia), shorter hospital stay, reduced postoperative pain, earlier return to work, and cosmetic advantage.
Anal fistulae are a difficult problem to treat. The optimal treatment for fistula involving the anal sphincter is unclear. Two standardly used methods of treatment are the ligation of intersphincteric fistula track (LIFT) procedure and the use of an anal fistula plug. The purpose of this study is to exam the rate of fistula closure between the LIFT procedure and the use of a fistula plug
