Filter by:Perianal fistula is a common anal problem. It needs only surgery. MRI is the best preoperative diagnostic tool, but it is demanding as it is expensive, time consuming and needs an experienced radiologist. So, we tried to find an alternative diagnostic tool which is cheaper, time saving and accurate and comparing its preoperative reports with intraoperative findings. study was held in surgery department in Zagazig University Hospitals from September 2023 to March 2024. It included 93 patients with perianal fistula who were diagnosed clinically and radiological by trans recto-perineal ultrasound and comparing pre-operative ultrasound findings with intra-operative surgical findings.
This study investigated the cellular and molecular characteristics of AT-MSCs obtained from autologous AT therapy in patients with high transphincteric perianal fistulas of crytoglandular origin. Adipose tissue was injected into anal fistulas. Characteristics of adipose tissue mesenchymal stemcells (AT-MSC) was investigated and compared in patients with fistula that healed after the treatment (responders) to patients who failed to heal (non-responders)
The purpose of this study is to gain a better understanding of the disease burden and unmet need of perianal fistulas within Crohn's disease (CD) in Ontario.
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.
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.
This study is an extension to re-treat partial and non-responders from the previously approved Phase 1 MCS-AFP protocols IRB #12-009716 (Crohn's Disease perianal fistulas) and 15-003200 (cryptoglandular perianal fistulas).
