The purpose of this study is to determine if endothelial cells derived from human umbilical vein are safe for use in conjunction with fistulotomy for the treatment of simple anal fistulas. Endothelial cells are a special kind of cell in the body that line the inside surface of blood vessels. The goal of the study is to evaluate the preliminary safety of human umbilical vein cells in anal fistula healing.
Anal Fistula can be a challenging condition to treat. Microdialysis has never before been used to examine the inner environment of anal fistula. This is now going to be performed.
Laser closure of the perianal fistula is the minimally invasive and low complication rate procedure which is a life-saving way for complex fistulas, preserving anal sphincter injury. Unfortunately, wide range success rate reported before (30-80%), the investigators are searching to reach better rates. Internal closure of the fistula orifice offered by some authors. The investigators are aimed to identify the efficiency of this.
The optimal method of surgical treatment of complex anorectal fistulas has not been found yet. The aim of this study is to compare two techniques in treatment of high anorectal fistulas. This study purpose to demonstrate that the fistulectomy with dissection from 1/3 to 2/3 of the height of the sphincter complex with primary suturing is technically simpler, equally effective and safe in comparison with muco-muscular endorectal advancement flap.
Fistula is a pathology that can be complex and lead to treatment difficulties for the proctologist. The proctologist's objective is to treat the infection (anal fistula and abscess) with the minimum impact on anal continence. Drainage of the fistula pathway(s) and removal of infected tissue during initial surgery are essential. The treatment of upper trans-sphincterial fistulas, i. e. those that span more than half the height of the anal sphincter, poses risks to anal continence. It sometimes requires several times of surgical treatment. The study aim to investigate the fate of all patients treated for anal fistula in an expert team, in terms of impact on healing and anal continence and according to the type of anal fistula, the co-morbidity, the surgical techniques used and the bacterial flora responsible.
Prospective comparative parallel ultrasound diagnostic transrectal study in the diagnosis of cryptogenic fistulas of the rectum
This is a randomized, controlled, parallel study to compare the results of treatment for patients with transsphincteric fistulas-in-ano.
BACKGROUND Anal abscess and perianal fistula is a high prevalence disorder in general population that affect adult patients on young ages, affecting them significantly their social and quality of life. There is clinical evidence that the origin of most perianal fistulas (60%) is with an episode one year before of a perianal abscess. In fact, the established cryptoglandular hypothesis considered the origin of anal fistula, a chronic infectious disease starting on a clinical episode of an anal glands abscess. However, controversy exists regarding the role of antibiotics in the development of anal fistula after incision and drainage of perianal abscess. Nowadays, only two single-centre randomized controlled trials has been published addressing this issue, with inconclusive results. The MAIN OBJECTIVE of the study is to examine the clinical benefit of antibiotic therapy in patients with a perianal abscess, to avoid the development of a perianal fistula. METHODOLOGY We designed a prospective, multicentre double-blind placebo trial to analyse the clinical benefit of a course of antibiotics after perianal abscess drainage to diminish the probability of development of perianal fistula in the follow up of patients. Patients with anal abscess will be allocated randomly either to receive 7 days of oral metronidazole/ciprofloxacin in addition to their standard care or to receive standard care and placebo, after they will be discharged from the hospital. Patients will be followed clinically at different intervals during one year in order to know if they develop anal fistula. Also a quality of life assessment at the end of the study will be evaluated. EXPECTED RESULTS We expected that patients allocated to antibiotic treatment would develop a significant less anal fistulas in their follow-up with a related significant better quality of life. Thus, a change on standard of care led by our group, may be achieved.
Patients with anal fistula who will undergo anal fistulotomy will be randomized into one of two groups; the first group will receive topical phenytoin therapy postoperatively and the second group will not receive such topical treatment.
