Active clinical trials for "Fistula"

The purpose of this study is to compare the clinical effectiveness of augmenting surgical repair of complex anal fistula using autologous PRP and/or micronized acellular porcine urinary bladder matrix (UBM) to usual surgical care alone to prevent fistula recurrence or improve HRQoL, to compare the effects of augmenting surgical repair of complex anal fistula using autologous PRP and/or micronized acellular porcine urinary bladder matrix on early postoperative pain and fecal continence and to assess the cost utility of augmented complex fistula repair relative to usual surgical care

The purpose of this protocol is to determine the safety and efficacy of abdominal wall transplantation as a treatment for the reconstruction of abdominal wall defects. Abdominal wall transplantation may be performed alone or in combination with another transplant.

Drainage of perianal abscesses is a well established treatment. Traditionally its been done in general anesthesia after the swelling has been localised its been drained with a knife. After surgical intervention complications can occur with recidivism, chronic fistulas that go from the anal to the skin and sometimes the anal sphincter is damaged which can cause problems with incontinence. Through ultrasound the abscess is opened under more controlled forms with a better visual overview. This is a new technique that has not been tested in larger studies. The aim with ultrasound-drainage as with traditional incision to drain the abscess so that the infected area can heal. The hypothesis is a reduction of recurrences and formation of fistulas with the use of 3D ultrasonography.

The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with fistulizing Crohn's disease. Autologous means these cells to coat the plug come from the patient.

The study aims to evaluate effectiveness of the association of endorectal advancement flap technique with local injection of autologous and micro-fragmented adipose tissue, obtained with the Lipogems® system, in patients with complex Perianal Fistulas not related to Crohn's Disease.

This phase II trial studies the effect of botulinum toxin (Botox) in preventing postoperative pancreatic fistula after distal pancreatectomy. Postoperative pancreatic fistula (POPF) is a known risk of distal pancreatic surgery, in which leakage of pancreatic digestive liquids causes internal swelling that can be painful (termed inflammation). A valve-like muscle, called the Sphincter of Oddi, opens and closes, controlling the flow of digestive liquids from the liver (bile) and pancreas (pancreatic juice) to the small intestine (duodenum). After surgery, the Sphincter of Oddi may act to block the flow of normal pancreatic secretions, causing secretions to leak into the abdomen resulting in POPF. Botox is a drug that can cause paralysis of muscles. Giving an injection of Botox into the sphincter of Oddi before distal pancreatic surgery may reduce leakage of digestive fluids and potential POPF.

Hidradenitis suppurativa (HS) is a common chronic skin disease where patients experience inflamed painful nodules and chronic suppurating tunnels under the skin that often leave mutilating scars. Symptoms typically begin during adolescence and patients struggle with pain, pruritus, malodor and purulent discharge compromising work life, physical exercise, and sexual habits. Consequently, the risk of social exclusion, anxiety, depression, and suicide is increased among patients suffering from HS. Creams, tablets, and injections aim to gain disease control, yet are sometimes not sufficient. Once HS tunnels have formed, surgical intervention is often required. Recently, emergence of flexible diode laser fibers has enabled treatment of tunnels from within. The technique has been tested for perianal tunnels and in few studies also for HS tunnels with promising results. Overall, the laser fiber technique is still new, and knowledge of optimal treatment settings is sparse. However, there is reason to believe that intralesional laser fiber treatment of HS tunnels may provide a new tissue-sparing alternative to conventional surgical techniques with a potential to produce fewer side effects, less scaring, shorter downtime after surgery and possibly, also improved inflammatory control. This study aims to investigate the efficacy and safety of laser fiber treatment of HS tunnels. Method The project is carried out at the Dermatological Department, Roskilde University Hospital under the leadership of principal investigator Professor DmSc Gregor Jemec. A prospective cohort study of intralesional laser fiber treatment of HS fistulas is planned. After signing informed consent, patients with two comparable HS tunnels in typical areas will draw lot to receive experimental laser fiber treatment of one tunnel while the other tunnel serve as control. Efficacy will be monitored by pain scores, ultrasound, clinical photos, clinical measures of disease activity, quality-of-life scores, and skin biopsies. Patients will be followed 2, 6, 12 weeks and if possible, also 52 weeks after treatment. After 12 weeks, patients will be offered laser fiber treatment or standard of care surgery to the untreated control tunnel.

In treatment of perianal fistula several methods are described. However, since the Hippocrates basics of surgical treatment has not changed very much. the aim of this study is to evaluate the effectiveness of PRP gel in treatment of perianal fistula.

The purpose of this study is to determine the safety and efficacy of using adult allogeneic bone marrow derived mesenchymal stem cells (MSCs), to treat people for medically refractory perianal fistulizing Crohn's disease.

Multi-center trial to assess the feasibility and safety of the EchoMark LP and the EchoMark diagnostic ultrasound system for assessing AV fistula blood flow, diameter, and depth.
