Comparative Study of Glyceryl Trinitrate Ointment Versus Surgical Management of Chronic Anal Fissure
Indian Journal of …, 2011
Chronic Anal Fissure (CAF) is common perineal condition and well-known painful entity. Standard surgical treatment even though available, may require long hospital stay and sometimes have worrying complications like anal incontinence. So non-surgical treatment, Glyceryl Trinitrate has been shown to be an effective for chronic anal fissure. It decreases anal tone and ultimately heals the anal fissure. The present study is the attempt to know the efficacy of 0.2% Glyceryl Trinitrate ointment in the treatment of chronic anal fissure and to compare the effectiveness of 0.2% Glyceryl Trinitrate ointment (GTN) versus fissurectomy with lateral internal sphincterotomy (LIS) and fissurectomy with posterior internal sphincterotomy (PIS) in the management of chronic anal fissure. This is a prospective comparative study of management of chronic anal fissure done in our hospital during the period of one and half year from October 2005 to March 2007. Thirty patients treated with 0.2% Glyceryl Trinitrate ointment and 30 patients treated with fissurectomy and lateral internal sphincterotomy and 30 patients treated with posterior internal sphincterotomy, for chronic anal fissure were selected for study. A single brand of 0.2% Glyceryl Trinitrate ointment (Nitrogesic) used for trial arm. Dose of administration was 1.5 cm to 2 cm in the anal canal with device provided by manufacturers of the proprietary preparation and applied twice a daily for 12 weeks. Patients were followed up for 12 weeks and thereafter evaluated for relief of symptoms in all three groups. Observations were recorded at 2 weeks; 6 weeks and 12 weeks of follow up period, regarding symptoms like pain and bleeding during defecation, healing of CAF and also for side effects like headache in GTN group and flatus, fecal incontinence in surgical groups. Data collected in proforma and analyzed. Study revealed CAF was more in male 59 patients (66%) than the female 31 patients (34%), the ratio being 1: 0.52. The maximum number of patients was encountered in the age group of 20 to 40 years with mean duration of age 34.14 years. In all three groups symptoms like pain, bleeding, constipation and sphincter spasm were present. Sentinel pile was present in 56% of the patients. Common site of fissure was found to be posterior in 94% of patients. Observations with respect to relief of pain, no bleeding and healing were recorded at 2, 6 and 12 weeks of duration. Lateral sphincterotomy remains effective but should be reserved for the patients who fail to respond to initial chemical sphincterotomy or GTN therapy. GTN is good alternative mode of therapy for patients who refuse surgery and prefer medical line of treatment.
Local Glyceryl Trinitrate Versus Lateral Internal Sphincterotomy in Management of Anal Fissure
World Journal of Colorectal Surgery, 2010
Introduction: Anal fissure is a common benign condition that can cause severe anal pain after defecation and bleeding. Symptoms from fissure cause considerable morbidity and reduction in quality of life. The aim of treatment is to reduce anal hvpertonia, which may improve anodermal blood flow and heal the fissure. Aim of the work: This study aimed to evaluate the effectiveness of local glyceryl trinitrate (GTN) versus surgical lateral internal sphincterotomy in the management of acute and chronic anal fissure. Patients and methods: In our present study we compared topical application of GTN on lipsomal base with the surgical procedure i.e. internal lateral sphincterotomy and according to the method of treatment the patients were divided into two groups; group 1 which included 40 patients with anal fissure and agreed to have the medical treatment with topical GTN 0.2% applied to the anoderm twice daily. Group 2 also included 40 patients and treated with lateral internal sphincterotomy. Results: In group1, healing of fissures occurred in 85% of patients after 8 weeks therapy. Headache as a side effect developed in 65% of patients but no patient ceased to apply the ointment due to headache. In group 2, healing occurred in 97.5% of patients after 8 weeks. Incontinence to flatus occurred in 3 patients (7.5%) and mild soiling occurred in 2 patients (5%), but all were temporary and there was no gross incontinence and one patient with wound infection. The improvement in group 2 faster than group 1 but at the end of 8 weeks both groups become equal in pain score. The main anal resting pressure (MARP) assessment changes in the two groups were nearly equal. Conclusion: We concluded that topical application of nitroglycerin represents a new easily handled and effective alternative in the treatment of anal fissure.
Glyceryl trinitrate ointment for the treatment of chronic anal fissure
Diseases of The Colon & Rectum, 1999
PURPOSE: A randomized, double-blind, placebo-controlled trial was performed to test the effect of intra-anal glyceryl trinitrate ointment in patients with chronic anal fissures that would normally have been treated by sphincterotomy. Long-term follow-up was then performed to assess fissure healing. METHODS: Patients with chronic anal fissures were randomly assigned to 0.2 percent topical glyceryl trinitrate ointment or placebo. Anal manometry was performed before treatment, one week later, and 48 hours after treatment ceased at four weeks. Fissure healing was assessed by an observer blinded to the treatment arm. Pain was recorded on a linear analog scale. At the completion of the trial, treatment was continued with glyceryl trinitrate until fissure healing was obtained or lateral sphincterotomy was performed if required for ongoing pain. A long-term follow-up assessment was made at a mean of 29 (range, 25–33) months. RESULTS: There was a significant reduction in anal resting pressure at Week 1 with glyceryl trinitrate (P=0.001) but not placebo, and at Week 4 there was a significant reduction in pain score with glyceryl trinitrate (P=0.001) and placebo (P=0.01) and a significant reduction in fissure grade with glyceryl trinitrate (P=0.0001) and placebo (P=0.02). Forty-six percent of fissures healed with glyceryl trinitrate and 16 percent healed with placebo (P=0.001). At long-term follow-up in 40 of 43 patients, 14 patients (35 percent) had undergone lateral sphincterotomy, and in the remainder who were treated with glyceryl trinitrate there was a significant reduction in pain score (P=0.0002). Seventeen patients attended for repeat manometry and fissures were healed with glyceryl trinitrate in ten (59 percent) cases. High internal sphincter pressures persisted at long-term follow-up in patients successfully treated with glyceryl trinitrate, indicating that the sphincter is the cause rather than effect of anal fissure. CONCLUSION: Topical glyceryl trinitrate produces a successful internal sphincterotomy, which resulted in long-term healing of 59 percent of chronic anal fissures and significant improvement in pain. Internal sphincter spasm is the cause of chronic anal fissure.
Glyceryl trinitrate is an effective treatment for anal fissure
Diseases of the Colon & Rectum, 1997
It has been suggested that chronic anal fissure is ischemic in origin because of poor blood supply and spasm of the internal anal sphincter. Nitric oxide donors such as glyceryl trinitrate (GTN) cause a chemical sphincterotomy leading to healing of the fissure. This study addresses the hypothesis that topical GTN ointment may be an effective nonsurgical treatment for chronic anal fissure. Thirty-nine consecutive patients (23 women; median age, 34 (range, 16-54) years) with chronic anal fissure presenting to the surgical outpatient department were treated for four to six weeks with 0.2 percent GTN ointment applied twice daily to the anoderm. Maximum anal resting pressure was measured at steady state before and after application of the ointment at the first visit. Patients were assessed at two weekly intervals. Previous surgery for fissure had been performed in seven patients. There were 30 posterior and 9 anterior fissures. Resting maximum anal resting pressure fell from 122.1 +/- 44 to 72.5 +/- 33.3 cm of water (mean +/- standard deviation) by 20 minutes after application of ointment (P < 0.0001; paired t-test). Healing was complete in 14 patients at four weeks and in 33 patients at six weeks. Fissures recurred in five patients after treatment had been stopped. Four recurrences were successfully treated by further GTN ointment and one by sphincterotomy. This study shows that most anal fissures can be treated nonsurgically with topically applied 0.2 percent GTN ointment. Prospective, randomized controlled trials are now needed, because nonsurgical treatment of anal fissure avoids permanent division of part of the sphincter and the consequent disturbance of continence mechanisms.

Anal fissure is most commonly treated surgically by internal anal sphincterotomy. However, there is some concern over the effects of this procedure on continence. Nitric oxide donors such as glyceryl trinitrate (GTN) have been shown to cause a reversible chemical sphincterotomy capable of healing fissures in a small series of cases. This study reports a prospective, randomised, double-blind, placebo-controlled trial to test the hypothesis that topical GTN is the best first-line treatment for chronic anal fissure. 80 consecutive patients were randomised to receive treatments with topical 0.2% GTN ointment or placebo. Maximum anal resting pressure (MARP) was measured with a constantly perfused side-hole catheter before and after the first application of trial ointment. Anodermal blood flow was measured during manometry by laser Doppler flowmetry. After initial treatments, patients were given a supply of ointment (either GTN or placebo) to be applied to the lower anal canal twice daily. Patients were reviewed 2-weekly. At the initial and follow up visits patients were asked to record pain experienced on defaecation on a linear analogue pain score. Endpoints were healing of the fissure or condition after 8 weeks of treatment. After 8 weeks, healing was observed in 26/38 (68%) patients treated with GTN and in 3/39 (8%) patients treated with placebo (p < 0.0001, chi 2 test). Linear analogue pain score fell significantly in both groups after 2 weeks of treatment. This fall was maintained in those treated with GTN but pain scores returned to pre-treatment values by 4 weeks on treatment with placebo. MARP fell significantly from a mean of 115.9 (SD 31.6) to 75.9 (30.1) cm H2O (p < 0.001, Student's paired t-test) in patients treated with GTN but no change was seen in MARP after placebo. Anodermal blood flow measured by laser Doppler flowmetry significantly increased after application of GTN ointment but was unaffected by placebo. Topical GTN provides rapid, sustained relief of pain in patients with anal fissure. Over two-thirds of patients treated in this way avoided surgery which would otherwise have been required for healing. Long-term follow up is needed to assess the risk of recurrent fissure in patients with GTN.

Background and aims Anorectal pressure studies have demonstrated internal anal sphincter (IAS) hypertonia in patients with chronic anal fissure. It is unknown however, if these changes in IAS function are associated with any abnormality in sphincter morphology. The first aim was to investigate the clinical characteristics and the manometric and endosonographic findings of the IAS in a cohort of patients with chronic anal fissure. The second aim was to investigate the association between these findings and the outcome with topical Glyceryl trinitrate (GTN) therapy. Materials and methods All patients who presented with chronic anal fissure from November 1999 to May 2004 were included after failure of conservative therapy. Anorectal manometry and anal endosonography were performed before treatment with 0.2% GTN ointment twice daily was initiated. Patients were evaluated after 8 weeks. Results One hundred and twenty-four patients (66 women, mean age, 45.2±14.8 years) were included. Hype...

Anal fissure is one of the most common lesions to be considered in the differential diagnosis of anal pain. It typically causes episodic pain that occurs during defecation and persists for hours afterward. It is a common problem that causes significant morbidity. Majority of fissures are acute and resolve within 6-8 week with conservative treatment. Chronic anal fissures are associated with hypertonia of the anal canal and reduction in mucosal blood flow, with microcirculatory disturbance and a poor healing tendency. Knowledge of ABSTRACT

Anal fissure is a linear tear in the distal anal canal resulting from persistent hypertonia and spasm of the internal sphincter which results in mucosal ischemia. We have conducted a study in order to compare the outcome of 0.2% glyceryl trinitrate cream versus 2% diltiazem cream in the treatment of chronic anal fissure. This randomized controlled trial (RCT) was carried out in the Department of Surgical "B" unit, at Ayub Teaching Hospital, Abbottabad, Pakistan from 15th June 2012 to 15th May 2015. One hundred and eighty-four patients who visited the outpatient department for the treatment of chronic anal fissure were included in the study. They were divided into two groups with 92 patients in each group. Patients in group "A" included those patients receiving topical glyceryl trinitrate and group "B" patients were those receiving topical diltiazem cream. Out of 184 patients 66.3% were males, 33.7% were females. Mean age of the patients was 43.84±7.976 ...
