Filter by:The purpose of this study is to collect data about the efficacy of Permacol Paste treatment in perianal Crohn's Disease.
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 .
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.
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.
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.
The aim of this study is to evaluate whether a local perianal block performed during a proctological intervention can reduce the postoperative pain.
Perianal Crohn's disease (pCD) is the commonest form of fistulising Crohn's disease, with up to 38% of patients affected and with 30% of them experiencing recurring disease symptoms. Presence of fistula can lead to major morbidity due to cutaneous perianal abscess formation or drainage. To date, it is very difficult to quantify inflammation in patients with pCD due to the absence of reliable disease activity measurements. In addition to this, optimising therapies for pCD is quite challenging and may have a major impact on quality of life. Magnetic resonance imaging of pelvic is a standard examination for the anatomical evaluation of pCD which is significant in terms of surgical therapy and progress. The overall hypothesis is that newer MRI techniques such as magnetization transfer (MT), diffusion weighted image ( DWI) and dynamic contract enhancement (DCE) are better suited to measuring the inflammatory vs fibrotic burden in pCD. The aim of this project is to measure disease activity within pCD and luminal CD using MRI sequences before and after biological therapy
In this pilot study a new surgical treatment approach for perianal fistulae, called Fistulodesis, is performed. The study aims to assess effectiveness, safety and tolerability of the Fistulodesis procedure. The investigators are aiming to include 20 patients with Crohn's disease and 20 patients without underlying Crohn's disease. It is an open label study with an anticipated duration from January 2017 to January 2020.
Evaluation of the anesthetic quality and analgesic efficacy of adding ketamine to intrathecal bupivavaine in selective saddle block for perianal surgery.
