conclusion the dwmri is a useful technique for evaluating activity of fistulas with abscess. perianal fistula visibility is greater with combined t2wi and dwmri than t2wi alone. patients and methods fifty-three patients with 56 perianal fistulas were included in the current retrospective study. the t2-weighted imaging (t2wi) and dwmri were performed and apparent diffusion coefficient (adc) valu...

Background: Perianal fistula is a complicated disorder and most difficult to manage. New treatment methods would help surgeons to achieve a better outcome in patients with perianal fistula. Human amniotic membrane (HAM) has positive effects on wound healing in several conditions. The present study aimed to further determine the effect of HAM on wound healing of perianal fistula in rabbits.Metho...

background: fistula-in-ano is a problematic perianal disease for physicians and patients because of its occasional difficulty in management. due to the different types of fistulas seen in patients, careful approach is necessary to correctly choose from among the various surgical techniques. one surgical method for complex fistula is the endorectal advancement flap which has been frequently perf...

Perianal fistula formation is a rare complication in children after rectal biopsy. Perianal fistula may become difficult to treat; therefore a lot of surgical options are present. One of these options is video assisted anal fistula treatment (VAAFT). We present a 6-year-old female who developed perianal fistula following rectal biopsy for which VAAFT was done successfully.

Perianal fistula is a very common problem in general population. Ninety percent of perianal fistulae arise from infected anal glands, and they often give rise to perianal abscesses. Very rarely perianal fistulae and abscesses undergo malignant transformation and give rise to carcinomas, mainly adenocarcinomas. We are reporting a case of squamous cell carcinoma arising from long-standing periana...

Fistulotomy alone induced remission in 85% of patients with simple perianal fistula without rectal inflammation. However, if active inflammation is present in the rectum, the risk of delayed healing or fecal incontinence increases after fistulotomy. Therefore, a noncutting seton placement is preferred, along with appropriate medical treatment when active inflammation is present. The introductio...

Colonic adenocarcinoma revealed by metastatic anorectal fistula is rare, with few cases in the literature. Such lesions can be taken for the more common manifestation of a benign perianal abscess or fistula. Once diagnosed, the management of such conditions remains controversial. We herein report two cases with perianal fistula that were subsequently found to have developed perianal adenocarcin...

BACKGROUND/PURPOSE Fistulotomy is the accepted treatment for infants with perianal fistula. Although recurrence rates range from 0% to 68%. Based on the experience of a senior colleague who noted that babies suffering from perianal fistula follow a self-limited course the authors decided to determine if this observation was accurate. METHODS A conservative approach to perianal abscess and fis...

BACKGROUND AND AIM Appropriate treatment of perianal fistulas in Crohn's disease (CD) involves accurate anatomic evaluation. EUS is an accepted imaging method for this purpose. The aim of the current study was to evaluate the clinical and endosonographic characteristics of perianal fistula in CD and to assess its impact on therapy. METHODS All CD patients referred to the Sheba medical center ...

BACKGROUND Low transsphincteric fistulas less than 1/3 of the sphincter complex are easy to treat by fistulotomy with a high success rate. High transsphincteric fistulas remain a surgical challenge. Various surgical procedures are available, but recurrence rates of these techniques are disappointingly high. The mucosal flap advancement is considered the gold standard for the treatment of high p...
