Shiraz University of Medical Sciences140 enrolled

Overview

Anal fissure define as a superficial tearing in mucosa on the anoderm surface distal to dentate line . The most important factor is hard stool passing with trauma to anal mucosa. But, diarrhea diarrhea has been another important etiology that happen after some conditions like gastroenteritis, laxative over use, during chemotherapy, and ulcerative colitis exacerbation . In these conditions, it seems the change of stool PH maybe the main reason of inflammation and ulcer in acute phase. The treatment of acute is medical management with change in bowel habits and conservative therapy such as local lubricant, local vasodilator, and warm sitz bath to improve blood supply and wound healing. This research clinical trial is designed to show the effect of Asacol suppository in the management of acute fissure due to diarrhea. The hypothesis of this research clinical trial has been referred to the cause of acute fissure ulcer because of diarrhea.

The cases with acute anal fissure after diarrhea will included in this research clinical trial. They will be divided in two groups as an interventional group and control by blind randomization allocation. The interventional group will have received Asacol suppository 1 supp every night and Diltiazem jelly (standard management) twice per day. The control group will have received Diltiazem jelly and placebo suppository like interventional group. Both group will have used warm sitz bath with enough hydration for 10 days. Then the patients will have visited by another surgeon after 4 weeks to evaluate the healing of acute anal fissure. Pain will have performed if the patients can tolerate.

Interventions

Asacol is used to treat and prevent mild to moderate acute fissure diseaseDRUG

Comparison of two groups after 2 weeks in fissure wound healing, pain relief, pruritus, burning, bleeding, incontinence. Preliminary results of the study show the rate of fissure improvement 6 weeks after treatment, which is observed by clinical examination. Restoration is defined by complete epithelialization of the fissure site without scarring or residual cracks, and the secondary results will be a reduction in the amount of pain and other symptoms.

Outcomes

Primary Outcomes

Acute anal fissure after diarrhea. Standard management of acute fissure (Diltiazem Jelly, supportive care, placebo suppository, sitz bath)

bleeding anal fissure. After 2weeks the patients will visit. The score of pain, burning sensation, bleeding and improvement will be recorded in two groups. Score of pain with visual analog scale (VAS) is a tool widely used to measure pain; Scale (0-10) that higher grade means higher pain. Burning sensation (yes, no) and bleeding (yes, no) and improvement (yes, no) will be recorded

Time frame: 2 weeks

Secondary Outcomes

Acute anal fissure after diarrhea. Intervention group (Asacol suppository, supportive care, placebo suppository, sitz bath)

need surgery or botox injection. Both group including 70 patients that will visit after 2 weeks for evaluating heading acute fissure by history and physical examination. Bleeding(decrease/increase) Pruritus(decrease/increase) Wound healing (according to surgeon evaluation)

Time frame: 3 months
