Filter by:Aim of the study is to evaluate long-term success rate of Biodesign® anal fistula plug for treatment of complex trans-sphincteric anal fistulas.
The study aims to evaluate the use of 3D endoanal ultrasound in preoperative management of anal fistula disease.
Objective: Validate and analyze the results of intralesional photodynamic therapy in the treatment of complex anal fistula. Methods: Prospective observational study including patients treated for complex anal fistula who underwent intralesional photodynamic therapy (i-PDT). Patients were included with a minimum follow up of 1-year, in order to evaluate recurrence, continence and postoperative morbidity. Intralesional 5-aminolevulinic acid gel 2% was directly injected into the fistula. The internal and external orifices were closed. After an incubation period of 2 h, the fistula was irradiated using an optical fibre connected to a red laser (MULTIDIODE 630 PDT, INTERmedic, Spain) operating at 1 W/ cm for 3 min (180 Joules).
Present study investigated the efficacy of injection of freshly collected autologous adipose tissue into perianal fistulas in patients with Crohn's disease. Adipose tissue collected by liposuction was injected into the perianal fistulas. Primary objective was complete clinical healing six months after treatment. Secondary objectives were reduced or ceased fistula secretion and complications to the treatment.
It is a randomized control trial in which we will treat the patients with perianal fistula with seton placement. We will divide the patients in two groups. Group I will be treated with silk seton and Group II will be treated with prolene setone. The outcome will be then followed as fistula healing and recurrence.
This observational study aims at assessing the safety and efficacy profiles of mesenchymal stem cell, in different formats (SVF, autologous, allogenic), to treat complex perianal fistula according to the Spanish national Compassionate-use law .
Rationale: Perianal fistulas are a common incapacitating problem. Many patients are treated by seton drainage to prevent recurrent abscess formation. Nowadays, vessel loops or sutures are used for drainage. The knot of these seton drains can cause complaints of pain or tenderness if it presses against the external opening of the fistula or even slides in to the fistula tract. Medishield B.V. designed a knotless seton drain, the SuperSeton. This could decrease the pain complaints caused by the knot. Objective: The aim of this study is to determine the feasibility of SuperSeton placement in patients with perianal fistulas. Study design: The design of the study is a feasibility study. Study population: Patients (≥ 18 years) with perianal fistulas (ever) treated with a knotted seton are eligible. Intervention: The SuperSeton will be placed at the outpatient clinic in patients that already have a seton in situ. This seton will then be exchanged by the SuperSeton. In case patients do not have a seton in situ, the SuperSeton can be placed at the operating theatre in day care setting instead of a regular seton. Main study parameters/endpoints: The primary outcome is seton failure (loosening of the seton). Secondary outcomes are time of procedure, complications and quality of life measured by the PDAI ('Perianal Disease Activity Index'). Nature and extent of the burden and risks associated with participation: The SuperSeton will be placed in patients with perianal fistulas (ever) treated with a conventional knotted seton. There are no additional risks involved. The seton will be placed at the outpatient clinic in patients with a seton in situ, or at the operating theatre in day care setting in patients with a perianal abscess without a seton. The material that is used for the Setons is of medical grade polyurethane, this is the same material of catheters that are already used in clinical practice (instech BTPU 027). The Setons including the insert (BTPU) are supplied sterile (Synergy Health). Sample size calculation: A group of 60 patients will be included to determine feasibility of the SuperSeton. The proposed treatment protocol is considered feasible if at least 70% of the SuperSetons stay in place.
This randomized trial aimed to compare conventional draining seton with or without rerouting of the fistula track in treatment of complex anal fistula
Patients with simple anal fistula will undergo fistulotomy operation and will be divided into two groups: the first will undergo marsupialization of the laid open fistula track and second group will not undergo marsupialization. The effect of marsupialization on healing of anal fistula will be compared postoperatively.
The study aims to evaluate safety, feasibility and effectiveness of local injections of autologous and micro-fragmented adipose tissue obtained with the Lipogems® system in patients with refractory complex fistulizing perianal Crohn's disease.
