Filter by:The goal of this observational study is to understand the effects of anatomical factors, etiology, and complexity of anal fistula on the prognosis of patients undergoing anal fistula surgery within one year post-operation.The main question it aims to answer is: Which factors are indicative of the prognosis of anal fistula surgery? Which factors are landmark factors of anal fistulas? Participants who have already undergone anal fistula surgery at our hospital will receive outpatient and telephone follow-up to assess their prognosis.
The purpose of this study is to compare aspiration and oral antibiotics with surgical incision in the treatment of perianal abscesses in terms of recurrence and subsequent fistula formation. Included patients will be randomised to either aspiration or incision.
The study is designed as a prospective, non-randomized clinical trial comparing safety and effectiveness of the CuraSeal PICS-AF device to historical data from commercially available devices for the treatment of anorectal fistulas.
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.
Surgical treatment of perianal fistulas frequently affects fecal continence. Sphincter saving techniques like loose or cutting seton and fistulectomy with advancement of an endorectal flap have been advocated to minimize the risk of sphincter injury, but patients often complain of a prolonged healing period and major discomfort. Furthermore, the healing rate varies widely according to the type of fistula and the surgeon's experience.In the early '90s the treatment of perianal fistulas by autologous or commercial fibrin glue was suggested and the American FDA approved the use and marketing of a human fibrin glue in 1998. Since then, several studies have evaluated the effectiveness of human fibrin glue in the treatment of different types of perianal fistulas, reporting a wide range of success rates ranging from 31 to 85%. Primary aim of this study is to conduct a prospective randomized trial evaluating the effectiveness of glue treatment of perianal fistulas as compared with the classical seton treatment. Secondary aims are to compare postoperative faecal incontinence, postoperative anal pain, healing time and length of hospitalization.
