Filter by:The purpose of this study is to determine effective incision type for the treatment of chronic anal fissures.
This is an open label study. The study will consist of 1 treatment group: coated Nifedipine suppository containing 12 mg of Nifedipine, administered BID to subjects with chronic anal fissure.
The standard treatment of anal fissure in the netherlands (ISDN ointment) is being compared to a relatively new treatment (injection of Botox in the internal anal sphincter). The study hypothesis is that after 4 months, Botox has healed more patients than ISDN. The comparison is done blinded for the surgeon and the patient.
Anal fissure is a solitary ulcer in the squamous epithelium of the anus causing intense anal pain especially upon defecation and for one or two hours afterwards. There are no approved drugs in the US for this condition and surgery is often the treatment choice. Strakan is conducting this confirmatory study so the product can be submitted for regulatory approval in the US. Strakan currently markets this product throughout Europe. To determine the effect of Cellegesic versus placebo on average pain intensity over every 24 hour period for up to 21 days of treatment in 250 patients.
Chronic anal fissure is a linear tear in the distal anal canal. Most chronic fissures require intervention to heal. Surgical sphincterotomy is currently performed. However, the procedure permanently weakens the internal sphincter and may be associated with permanent complications such as incontinence. Current topical treatment or " chemical sphincterotomy" is effective in the short term for about 70% of the patient more than 50% of them will suffer from recurrence. Number of studies support the hypothesis that local ischemia is the reason for failure to heal in anal fissure. Treatment of refractory wounds by macrophage suspension is an innovative method since 1995, macrophage suspensions have been used successfully in more than 1400 patients in several hospitals in Israel without any side effect.Macrophages have key function in almost every stage of wound healing. They help in the digestion of bacteria, in a later stage, they secret IL-6, which influences endothelial cell proliferation and the initiation of angiogenesis. The study hypothesis is that local injection of activated human macrophages into chronic anal fissure may induce fissure healing.
24 patients randomly divided into two groups, one of the groups receiving atropine in addition to the planned anaesthesia. Skin conductance parameters to be compared between the two groups.
To evaluate the effect on healing rates of two different prognostic factors in patients treated with Dysport® for anal fissure: duration of fissure and dose of study drug
To demonstrate that lactulose acts as a stool softener, relieving the pain at defecation, improving the number of defecations and regulating the colonic transit time in patients suffering of hemorrhoids or anal fissure. To compare efficacy and quality of life in patients treated either with lactulose or plantago ovate.
