Long-term follow-up after combined fissurectomy and Botox injection for chronic anal fissures.2007 Jan 30

Department for Visceral and Transplantation Surgery, University Hospital Zürich, Rämistrasse 100, 8091, Zurich, Switzerland, dieter.hahnloser@usz.ch.

BACKGROUND AND AIMS: Chronic anal fissures are difficult to treat. The aim of this retrospective study was to determine the outcome of combined fissurectomy and injection of botulinum toxin Type A (BT). MATERIALS AND METHODS: Between January 2001 and August 2004, 40 patients (21 women), median age 37 years (range 18 to 57), underwent fissurectomy and BT injection. Fissurectomy was performed followed by injection of 10 U of BT into the internal anal sphincter on both sides of the fissure. All patients were clinically checked 6 weeks after the operation. At 1 year, patients were sent a detailed questionnaire regarding symptoms, recurrence and further treatment for evaluation of long-term results. RESULTS/FINDINGS: At 6 weeks, 38 patients (95%) were free of symptoms. No adverse effects were detected. The response rate of questionnaires was 93%; the median follow-up was 1 year (range 0.9 to 1.6). In the long-term, a recurrence was found in four patients. These patients were treated successfully with repeated fissurectomy and BT injections and salvage procedures, respectively. Overall, the success rate of combined fissurectomy and BT injection was 79%. INTERPRETATION/CONCLUSION: Combined fissurectomy and Botox injection for chronic anal fissure is an excellent and safe procedure with low morbidity and a high healing rate.

Non surgical therapy for anal fissure.

Northern General Hospital, Department of General Surgery, Herries Road, Sheffield, UK. rick.nelson@sth.nhs.uk

BACKGROUND: Because of the disability associated with surgery for anal fissure and the risk of incontinence, medical alternatives for surgery have been sought. Most recently, pharmacologic methods that relax the anal smooth muscle, to accomplish reversibly what occurs in surgery, have been used to obtain fissure healing. OBJECTIVES: To assess the efficacy and morbidity of various medical therapies for anal fissure. SEARCH STRATEGY: Search terms include "anal fissure randomized". Timing from 1966 to May 2006. Further details of the search below. SELECTION CRITERIA: Studies in which participants were randomized to a non-surgical therapy for anal fissure. Comparison groups may include an operative procedure, an alternate medical therapy or placebo. Chronic fissure, acute fissure and fissure in children are included in the review. Atypical fissures associated with inflammatory bowel disease or cancer or anal infection are excluded. DATA COLLECTION AND ANALYSIS: Data were abstracted from published reports and meeting abstracts, assessing method of randomization, blinding, "intention to treat" and drop-outs, therapies, supportive measures (applied to both groups), dosing and frequency and cross-overs. Dichotomous outcome measures included Non-healing of the fissure (a combination of persistence and recurrence), and Adverse events (including incontinence, headache, infection, anaphylaxis). Continuous outcome measures included measures of pain relief and anorectal manometry. MAIN RESULTS: 48 different comparisons of the ability of medical therapies to heal anal fissure have been reported in 53 RCTs. Eleven agents were used (nitroglycerin ointment (GTN), isosorbide dinitrate, Botulinum toxin (Botox), diltiazem, nifedipine (Calcium channel blockers or CCBs), hydrocortisone, lignocaine, bran, minoxidil, indoramin, and placebo) as well as anal dilators and surgical sphincterotomy.GTN was found to be marginally but significantly better than placebo in healing anal fissure (48.6% vs. 37%, p < 0.004), but late recurrence of fissure was common, in the range of 50% of those initially cured. Botox and CCBs were equivalent to GTN in efficacy with fewer adverse events. No medical therapy came close to the efficacy of surgical sphincterotomy, though none in these RCTs was associated with the risk of incontinence. AUTHORS' CONCLUSIONS: Medical therapy for chronic anal fissure, acute fissure and fissure in children may be applied with a chance of cure that is marginally better than placebo, and, for chronic fissure in adults, far less effective than surgery.

Favourable results with local injections of botulinum-A toxin in patients with chronic isosorbide dinitrate ointment-resistant anal fissures]
Witte ME, Klaase JM.2006 Jul 8

Medisch Spectrum Twente, Afd. Chirurgie, Haaksbergerstraat 55, 7500 KA Enschede.

OBJECTIVE: To determine the effectiveness of injection of botulinum-A toxin in the internal anal sphincter as a treatment for chronic therapy-resistant anal fissures. DESIGN: Prospective. METHODS: In the period October 2002-February 2005, 32 consecutive patients (15 men and 17 women), with a median age of 44 years (range: 23-78 years) and suffering from chronic isosorbide dinitrate ointment-resistant anal fissures, were treated with an injection of 40 IU botulinum-A toxin (Dysport, Ipsen, The Netherlands) in the ventral side of the internal anal sphincter. The injection was given as an outpatient procedure under general or spinal anaesthesia. RESULTS: After a median follow-up of 14 months (range: 2-28 months), the chronic anal fissures were cured in 24 ofthe 32 patients (75%). Twenty-two patients were given a second or a third injection. A fissure recurred in one of the cured patients (4%), and one patient suffered from temporary flatus incontinence. CONCLUSION: Botulinum-A toxin injections were effective in 75% of patients with isosorbide dinitrate ointment-resistant chronic anal fissures. This is a simple technique with fewer side effects than local application of NO donors and fewer complications and less morbidity than surgical sphincterotomy.

Long-term results of "chemical sphincterotomy" for chronic anal fissure: a prospective study.
Lysy J, Israeli E, Levy S, Rozentzweig G, Strauss-Liviatan N, Goldin E.2006 Jun;49Gastroenterology Service, Division of Medicine, Hadassah University Hospital and Hebrew University Medical School, Jerusalem, Israel.INTRODUCTION: Pharmacologic anal sphincter relaxants promote fissure healing; however, their effect is transient and the risk of late recurrence remains uncertain. METHODS: From August 1997 to August 2002, patients with chronic anal fissure attending our outpatient clinic were treated with a protocol that included: topical isosorbide dinitrate, 2.5 mg, or nifedipine, 0.2 percent t.i.d., or the combination of both. Botulinum toxin 20 units was injected to the internal anal sphincter to those who failed. All the patients were contacted and interviewed during November to December 2002. RESULTS: Follow-up was a median of 47.43 +/- 13 (range, 4.7-60) months. A total of 455 patients completed the study; 323 patients (71 percent) healed at follow-up ending: 170 of the healed patients had one or more recurrences that responded to further treatment (37.4 percent), whereas 153 patients (33.6 percent) healed and had no recurrences. One hundred thirty-two patients (29 percent) did not heal and were referred to lateral sphincterotomy. Long intervals between symptoms appearance and treatment initiation decreased healing and increased recurrence rates (P = 0.03 and 0.01 respectively). CONCLUSIONS: Topical treatment is effective for patients with chronic anal fissure, at short-term and long-term periods. Because for many patients it is not a definitive treatment, it can be offered to those who are ready to receive repeated treatments. Longer intervals between symptom appearance and treatment initiation negatively affects fissure healing and recurrence rate.

Botulinum toxin and chronic anal fissure]
Daniel F, de Parades V, Siproudhis L, Atienza P.Service de Proctologie Médico-Interventionnelle, Groupe hospitalier Diaconesses, Croix Saint Simon, Paris.Lateral internal sphincterotomy is widely used in the treatment of chronic anal fissure. However, it is associated with a high rate of irreversible incontinence. For this reason the botulinum toxin has become a medical means of reversible sphincterotomy. Indeed, this neurotoxin induces relaxation of the smooth internal anal sphincter lasting one to three months after one injection. We reviewed the published studies about the use of this technique in the management of chronic anal fissure. Healing occurred in more than 70% of fissures without irreversible incontinence. Although further studies are needed to determine the best modalities of administration, especially due to the remaining significant recurrence rate, this toxin may be a valuable treatment for chronic anal fissure in the future.

Manometric factors associated with recurrence in botulinum toxin treatment for chronic anal fissure

Unidad de Coloproctología, Servicio de Cirugía General y Aparato Digestivo, Hospital General Universitario de Elche, Elche, Alicante, España. arroyocir@hotmail.com

INTRODUCTION AND AIM: To evaluate the effectiveness of botulinum toxin in the treatment of chronic anal fissure after long-term follow-up and establish the manometric factors related to recurrence. PATIENTS AND METHOD: We performed a prospective study in 50 consecutive patients with chronic anal fissure who were treated with 25 U botulinum toxin injected into the internal sphincter. Clinical and manometric parameters were recorded until the fourth year of follow-up. RESULTS: There was a tendency to progressive recurrence over time (54% at 4 years) associated with manometric factors indicating hyperexcitability of the internal anal sphincter (persistently elevated mean resting pressure, percentage of time with slow waves, and number of patients or percentage of time with ultra-slow waves after treatment). CONCLUSIONS: Treatment of chronic anal fissure with botulinum toxin leads to long-term cure in less than 50% of patients. In patients with manometric factors related to recurrence, this treatment is insufficient for definitive cure.

Fissurectomy-botulinum toxin: a novel sphincter-sparing procedure for medically resistant chronic anal fissure
Lindsey I, Cunningham C, Jones OM, Francis C, Mortensen NJ.2006 NovDepartment of Colorectal Surgery, John Radcliffe Hospital, Oxford, United Kingdom. lindseyilinz@yahoo.comBACKGROUND: Botulinum toxin heals only approximately one-half of glyceryl trinitrate-resistant chronic anal fissures, perhaps because chemical sphincterotomy alone treats internal sphincter spasm but not chronic fissure fibrosis. We aimed to assess whether a novel procedure, fissurectomy-botulinum toxin, improves the healing rate of medically resistant fissures over that achieved with botulinum toxin alone. METHODS: A prospective pilot study of chronic fissure patients failing medical therapy was undertaken. Fissurectomy was performed, with excision of the fibrotic fissure edges, curetting of the fissure base, and excision of the sentinel pile if present. Twenty-five units of botulinum toxin (Botox) were injected into the internal sphincter. The primary end point was fissure healing, and secondary end points were improvement in symptoms, need for lateral internal sphincterotomy, and side effects. RESULTS: Thirty patients underwent fissurectomy-botulinum toxin (57 percent female; median age, 39 years). Nineteen patients had failed glyceryl trinitrate, whereas 11 had failure of both glyceryl trinitrate and botulinum toxin. At a median of 16.4 weeks follow-up, 28 fissures (93 percent) were healed. Two fissures (7 percent) remained unhealed but were symptomatically better and avoided lateral internal sphincterotomy. Two patients (7 percent) experienced transitory flatus incontinence. CONCLUSION: Fissurectomy-botulinum toxin heals over 90 percent of fissures resistant to medical therapy. Fissurectomy-botulinum toxin allows patients with medically resistant fissures to achieve a high rate of healing while avoiding the risk of incontinence associated with lateral internal sphincterotomy.

The treatment of chronic anal fissure with botulinum toxin.
Godevenos D, Pikoulis E, Pavlakis E, Daskalakis P, Stathoulopoulos A, Gavrielatou E, Leppäniemi A.2004 OctDepartment of Surgery, University of Ioannina Medical School, Athens, Greece.BACKGROUND/AIMS: The aim of this study was to evaluate the effectiveness of botulinum toxin for the treatment of uncomplicated dorsal chronic idiopathic anal fissure. MATERIAL AND METHODS: Forty-five patients who reported post defecatory anal pain since two months or more were given a total of 20U botulinum toxin in the anal sphincter apparatus on both sides as well as below the anal fissure. RESULTS: Thirty-seven patients received a second session of 25U botulinum toxin injection. Thirty-five patients (78%) presented completely healed anal fissure, while ten needed lateral internal sphincterotomy. All patients were followed up for 8-36 months. Two patients relapsed. CONCLUSION: Local injection of botulinum toxin is a new and safe treatment; however, two sessions of injections are necessary to be effective and long-term follow-up to assess the recurrence rate of fissure is needed to evaluate further this method of treatment. Partial internal lateral sphincterotomy is no more the treatment of choice for chronic anal fissure.
