Eighteen patients with a clinical impression of a complex fistula in ano, had anal endosonography to delineate the anatomy of the fistula track and identify associated areas of sepsis. The clinical impression of a complex fistula was refuted by endosonography and subsequent surgical exploration in two cases. Horseshoe tracks were identified in nine (50%) patients and fluid collections, not evid...

rectovaginal fistula with atresia ani is a congenital condition that affects the anal opening and rectum by the formation of an abnormal connection between the rectum and vagina. this was diagnosed in a domestic short hair kitten. the presenting physical abnormalities included depression, dehydration, partial tail agenesis, anal atresia and a discharge of watery feces from the vaginal opening. ...

BACKGROUND Treatment of high anal fistulas may be associated with a high risk of continence disorders. Beside traditional procedure of flap-reconstruction the occlusion of the fistula tract using fistula-plugs offers a new sphincter-saving treatment option. In this study for the first time results from Germany are described. PATIENTS AND METHOD 40 patients (30 male, 10 female, age 51 ± 12 yea...

BACKGROUND Complex anal fistulas are unsuitable for fistulotomy because of the risk of fecal incontinence. The anal fistula plug (AFP) has demonstrated fistula healing without sphincter division. This study aims to evaluate the cost-effectiveness of the AFP compared to the endoanal advancement flap (EAAF) as an alternative sphincter-preserving option for complex anal fistulas. METHODS The stu...

Mucinous adenocarcinoma arising in chronic fistula-in-ano is rare, and diagnosing it at an early stage is difficult. The role of endoanal ultrasonography in diagnosing the condition has not been discussed in the study. Herein, we report three cases of mucinous adenocarcinoma arising from anal fistulas in which endosonography played an important role in diagnosing malignant change. Three male pa...

The accuracy of anal endosonography (AES) in diagnosing the type of anal fistula, according to different authors, is from 25% to 100% and in cases of recurrent fistulas is the lowest.1-4 In spite of underlined difficulties resulting first of all from impossibilities of the differentiation of fistula with scar, this problem has still not been examined exactly. This study presents the own results...

BACKGROUND Individuals with impaired immunity are at higher risk of perianal diseases. Concerning complex anal fistulas impaired healing and complication rates are also higher. Definitive treatment of a fistula aims controlling the purulent discharge and prevents its recurrence. It depends mainly on the trajectory of the fistula and the underlying disease. We present a case of a HIV-positive pa...

The fear of recurrence or impairment of continence following an operation of fistula in ano had compelled the surgeons to explore use of a variety of diagnostic aids to identify the offending tracts and an equal number of surgical procedures to reduce these risk factors. But despite all these attempts and trying a number of operative options, majority of surgeons still prefer the classical lay ...

Removal of the anal sacs is a frequently performed surgery in dogs. It is most often indicated for definitive treatment of chronic anal sacculitis. The anal sacs are intimately associated with the external anal sphincter; therefore, fecal incontinence resulting from damage to this muscle or its innervation is a potential complication of anal sacculectomy. Fistula formation and incisional infect...
