Outcomes of using CO2 (Carbon Dioxide) laser in the management of chronic anal fissure as an alternative to conventional methods
At a tertiary referral centre, 10 patients (4 male and 6 female; mean age 49.8 years) were given neuromodulation via the posterior tibial nerve to the sacral nerve for 30 min on 10 consecutive days. All patients had failed conventional medical treatment. The visual analogue scale (VAS), St. Marks score, Wexner`s constipation score, Brief Pain Inventory (BPI - SF), bleeding and mucosal healing were evaluated before treatment, at termination, after 3 months and then yearly during three years.
The objective of the study is to examine the effect of Nifedipine, applied intra-anally through our drug delivery device, on rectal pain severity in anal fissure patients that are being managed with conservative treatment.
Lateral internal sphinterotomy (LIS) is the gold standard against which all treatments are compared with a healing rate over 92%. However, the most serious complication of this procedure is anal incontinence. To overcome these problems, continued efforts are being tried to find less invasive treatments modalities for anal fissure that is as effective as surgical therapy with lower morbidity.
The investigators compared conventional lateral internal sphincterotomy (CLIS), V-Y anal flap, and combined tailored lateral internal sphincterotomy with V-Y anal flap (TLIS with V-YF) in a randomized prospective study in patients undergoing treatment for chronic anal fissure.
A Phase III, multicentre, randomised, double blind, placebo-controlled study in subjects having anal fissure (AF) with AF-related pain. Subjects will undertake a 1-week screening period to provide baseline data and for assessment of eligibility. At the Baseline visit (Week 0), eligible subjects (having an average Numerical Rating Scale (NRS) score of >4 for worst pain associated with or following defaecation) will be randomised on a 1:1:1 basis to one of the three treatment groups. Subjects will receive diltiazem hydrochloride 2% cream or diltiazem hydrochloride 4% cream or placebo cream. Study treatment will be applied in and around the anus, three times daily, for up to 8 weeks. Following the Week 0 Visit, subjects will be contacted by telephone during Week 1 to ensure adequate compliance with study treatment, to ensure that study drug is being tolerated and that any concomitant medications are used at a level consistent with that prior to randomisation. Subjects will return to the clinic for safety and efficacy assessments at Weeks 2, 4, and 8 and receive a follow-up telephone call at Week 12, following cessation of therapy. Concomitant laxatives and stool softeners will be permitted, as needed, during the entire study period (screening and treatment) to ensure that constipation or passage of hard stools does not confound evaluation or improvement of the condition. Fibre supplements will be allowed but should be continued at the baseline level. Instructions on the use of the Interactive Voice Response System (IVRS) diary will be issued to subjects to record fissure-related pain (NRS) and bowel symptoms daily during the 1-week screening period, to confirm eligibility and post-randomisation to record worst anal pain associated with or following defaecation (NRS) and daily overall AF-related pain (NRS). A record of the number of times the subject has defaecated, laxative and analgesic usage will also be made as well as the number of applications of study treatment, any changes to concurrent medications and any Adverse Events (AEs). In addition, at some or all study visits, subjects will record the Patient's Global Impression of Improvement (PGI-I) on a 7 point Likert scale, complete a Short Form 36 (SF-36) quality of life questionnaire and will undergo examination of their AF. Routine blood samples will be taken and the Skin Irritation Score (SIS) recorded for safety evaluations. Subjects may receive permitted medications for pain per Entry Criteria, but these should remain stable, where possible, up to the Week 8 Visit. Introduction of any new medication for AF will not be permitted unless the Investigator deems "rescue" intervention necessary. A subject will be deemed a treatment failure if rescue intervention is required and will have to be withdrawn from the study. Any subject leaving the study following randomisation for any reason will be asked to complete the Early Withdrawal Visit. This includes subjects who withdraw due to the development of AEs or intolerance, as well as subjects who require rescue intervention. These subjects will return for safety follow-up visits at their previously scheduled follow-up assessment appointments. If complete healing has occurred at the 2 or 4 Week visits, (i.e. prior to the end of the 8-week treatment period), subjects will be asked to continue applying the medication for the full 8 week course, up to the final assessment. Following the Week 8 visit (or Early Withdrawal Visit), subjects will be followed up for a further 4 weeks (following cessation of study medication) to note any AEs. All routine blood analyses (haematology and biochemistry) and plasma levels of diltiazem and of its principal metabolites will be analysed by central laboratories.
Perianal topical nitroglycerin has been widely used as a means for avoiding surgery in patients with anal fissure. However, nitroglycerin has not been universally accepted for this application because of inconsistency of efficacy and side effects. Recent studies (Dis Colon Rectum. 2007 Apr;50(4):509-16) have demonstrated that nitroglycerin ointment products compounded by pharmacies did not meet the USP specifications for potency and/or content uniformity when filling a prescription for 0.3 percent nitroglycerin ointment. These results raise significant issues as to whether the patient is put at undue risk relative to the relief of their anal fissure pain. In addition, one study (Dis Colon Rectum. 2006 Jun;49(6):865-8) has demonstrated that intra-anal dosing of topical nitroglycerin produces a significantly greater reduction in sphincteric pressure and lower incidence of headaches than with perianal administration of the same dose of ointment. Topical glyceryl trinitrate 0.4% ointment has been developed and tested in clinical trials and is effective in healing chronic anal fissures. It assures exactly dose and concentration of nitroglycerin. Hypothesis: The endoanal application of exactly dose and concentration of nitroglycerin must reduced headache and the final recurrence. The purpose of this study is: 1. Principal end-point: to compare perianal vs endoanal application of Rectogesic and evaluate the different morbidity of the two presentation
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.
