Botulinum toxin can chemically denervate striated muscle. Botulinum toxin A (15 U) was used to treat ten patients with chronic anal fissure by injection in the internal sphincter. In seven patients, the lesion healed at 2 months after treatment; one relapsed at 3 months. In one patient the lesion healed at 1 month, but partly relapsed a month later. Mild faecal incontinence lasting for 1 day wa...

PURPOSE Topical glyceryl trinitrate heals anal fissures, but a majority of patients experience headache. Topical gels of the calcium channel blocker diltiazem and the cholinomimetic bethanechol significantly lower anal sphincter pressure in volunteers. This study investigated the use of these two new pharmacologic agents in the treatment of patients with chronic anal fissure. METHODS Two stud...

To determine whether the medical Treatment of anal fissure can be an effective alternative for surgery Methods: Retrospectively, we randomly selected 190 Patients being treated for anal fissure between the years 2005-2010 in 3 equal groups: group A: Patients who received medical treatment with topical nitroglycerin, group B: Patient treated with topical diltiazem, and group C: Patients underwen...

PURPOSE To estimate the risk of recurrent fissure in ano after sphincter preserving treatments. METHODS A retrospective case note review, combined with a telephone survey was conducted for all patients treated for a chronic anal fissure between 1998 and 2008. RESULTS Six hundred and twelve patients (303 women: mean age, 39 years; range, 16-86 years) were treated for chronic anal fissure bet...

PURPOSE This study was designed to determine whether functional variations of internal sphincter activity occur in order to differentiate between patients with anal fissures from those with hemorrhoids. METHODS Thirty patients with chronic anal fissure (median age, 28 years; 12 females), 22 patients with hemorrhoids (median age, 37 years; 7 females), and 33 control volunteers (median age, 48....

Anal fissure is one of the most common as well as widespread benign diseases of the anus. Fissure development is initiated by a mechanical injury that is induced by hard faecal mass and remains unhealed if the blood flow in the tissue surrounding the fissure is reduced and the relaxation of the internal anal sphincter is impaired. Conservative treatment is administered as the initial treatment ...

PURPOSE Many kinds of substances are produced on vascular endothelial activation. The aim of this study is to confirm an increase in Endothelin-1 (ET-1), the most potent vasoconstrictor, which is produced by endothelial activation, in patients with chronic anal fissure and to infer the relationship between ET-1 and anal fissure chronicity. METHODS The study groups are divided into three diffe...
