Active clinical trials for "Fistula"

The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.

Background: Fistula in ano is one of the most common diseases of the ano rectal region. Treatment of Fistula in ano has puzzled the medical fraternity due to its complex nature. Commonly prevalent surgical treatment for anal Fistula, that is "Fistulectomy" does not provide successful cure for the disease, post operative complications and recurrences being common. Acharya Sushruta an ancient Indian Surgeon has described in his text ' Sushruta Samhita' about an ancient Ayurvedic technique of medicated thread called Ksharsutra treatment for Bhagandara ( Fistula in ano). Treatment of anal Fistula (Bhagandara)and Nadi-Vrana(Sinus) with Ksharsutra was practiced by Sushruta (1000-600B.C.) . Hypothesis: Aycharya Sushruta advocated Kshar Sutra therapy in Fistula in ano and in various types of Fistula.

The definition of biliary fistula is heterogeneous and the more accepted is that proposed by the ISGLS. We devised a precise definition of post-resectional biliary fistula and a well-established policy both for its disclosure and management.Aim was the validation of our definition, and management of biliary fistula after hepatic resection in a large prospective cohort of patients and its comparison with that of the International Study Group of Liver Surgery (ISGLS).

Patients that have undergone pre-operative radiation for pancreatic carcinoma, that upon pathologic examination of the normal portion of the pancreatic gland that was in the radiation field showed acute and chronic changes in the pancreatic cells. The hypothesis for utilizing stereotactic radiation on pancreatic fistulae is that the treatment will decrease pancreatic secretions, thus decreasing autodigestion.

Arteriovenous malformations (AVM) are abnormally formed blood vessels that can be located throughout the brain and spinal cord. Patients with abnormalities of the blood vessels located in and around the spinal cord can develop many neurological problems. Some problems include, weakness, pain, difficulty walking, paralysis, and even death. The treatment for these AVMs depends on their location, the type of malformation, the area of the spine involved, and the condition of the patient at the time of treatment. The treatment is aimed at stopping the neurologic problems from worsening and possibly correcting the existing problems. There are two commonly used treatments for AVMs, surgery and embolization (blocking off of blood flow to the AVM). However, researchers have limited experience treating these conditions because they are rare. In addition, it has been difficult to classify different kinds of AVMs and to develop new treatments for them. This study is designed to increase researchers understanding of AVMs by admitting and following patients diagnosed with the condition. By increasing the amount of patients studied diagnosed with spinal blood vessel abnormalities, researchers can begin to develop new management plans for patients with AVMs.

This trial aims to determine if intra-operative use of human dehydrated amnion chorion allograft improves post-operative patient healing outcomes.

The purpose of this study is to reduce the length of drainage using a treatment protocol to control the manipulation of the applied vacuum to the pleural cavity.

Newly formed dialysis fistulae can often fail, and failure is usually due to narrowing of the blood vessels. Methods of detecting narrowing are available and, more importantly, can detect narrowings before a fistula fails. It is not known whether treating these narrowings will actually improve fistula survival or if the majority can be left alone. we wish to see if we can detect such narrowings with ultrasound scanning and if early detection and treatment improves patient outcomes.

Phase of Investigation: First-in-human feasibility study Objectives: Primary objective: Demonstration that TIPS microspheres do not compromise the clinical condition or safety of the patient. Secondary objective: To demonstrate that TIPS microspheres facilitate natural healing in the context of perianal fistula. Type of Investigation: First-in-human single site, open label, feasibility study to assess the safety of TIPS microspheres in perianal fistulas and indicative functionality. Investigation design and methods: First-in-human single delivery of a bioabsorbable device to treat perianal fistula. A standard of care internal flap procedure performed to close the internal fistula opening and up to 300 mg of TIPS microspheres will be inserted into each perianal fistula. Participants will be assessed for healing, inflammation, abscess, sepsis, pain and continence by clinical assessments, blood tests, MRI and questionnaires.

Anal fistula treatment is associated with increasing risk of anal incontinence until 40% of cases. New and alternative treatments (glue, advancement flap, plug…) decrease this risk, but with fistula efficacy treatment in 40 to 60% of cases. Radiofrequency might destroy fistula tract without lesion of anal sphincter. Objective : Fistula healing rate and anal continence, 6 and 12 months after radiofrequency procedure. Methods : Clinical and MRI evaluation before, 6 and 12 months after treatment. Patients : 50 patients with low, high, complex and Crohn disease fistula. An intermediate analysis is expected after the first 20 patients, to verify morbidity. Evaluations : Fistula clinical healing 6 and 12 months after procedure Fistula MRI healing 12 months after procedure Anal continence before and after procedure Feasibility og radiofrequency procedure Morbidity Success and failure prognostics factors of this procedure
