Abstract
BACKGROUND There are multiple treatments for anal fissures. These range from medical treatment to surgical procedures, such as sphincterotomy. The aim of this study was to compare the relative clinical outcomes and effectiveness of interventional treatments for anal fissure. METHODS Randomized controlled trials were identified by means of a PRISMA-compliant systematic review using the Medline, EMBASE, and CENTRAL databases. Inclusion criteria were randomized controlled trials comparing treatments for anal fissure. A Bayesian network meta-analysis was performed using BUGSnet package in R. Outcomes of interest were healing (6-8-, 10-16-, and >16-week follow-up), symptom recurrence, pain (measured on a visual analog scale), and fecal or flatus incontinence. PROPSERO Registration: CRD42021229615. RESULTS Sixty-nine randomized controlled trials were included in the analysis. Lateral sphincterotomy remains the treatment with the highest odds of healing compared to botulinum toxin and medical therapy at all follow-up time points. There was no significant difference in healing between botulinum toxin and medical therapy at any time point. Advancement flap showed similar effectiveness compared to lateral sphincterotomy. Medical treatment and botulinum toxin had the highest pain scores at follow-up. Sphincterotomy had the highest odds of fecal and flatus incontinence. CONCLUSION Lateral sphincterotomy had the highest rates of healing and should be considered as the definitive treatment after failed initial therapy with botulinum toxin or medical treatment. Botulinum toxin was equally effective compared to medical treatment. Advancement flap shows similar effectiveness compared to lateral sphincterotomy, but more studies are needed to evaluate its efficacy.

Abstract
PURPOSE Anal fissure is caused by a pathological contraction of the internal anal sphincter. Lateral internal sphincterotomy remains the gold standard for the treatment of fissure. Botulinum toxin injections have been proposed to treat this condition without any risk of permanent injury of the internal sphincter. We investigate clinical and pathological variables and the effects of different dosage regimens of botulinum toxin to induce healing in patients with idiopathic anal fissure. METHODS This is a retrospective study at a single center. The patients underwent a pre-treatment evaluation that included clinical inspection of the fissure and anorectal manometry. We collected and analyzed demographic data, pathological variables, associated pathological conditions, and treatment variables. Success was defined as healing of the fissure, and improvement of symptoms was defined as asymptomatic persistent fissure. RESULTS The findings of 1003 patients treated with botulinum toxin injections were reported. At 2 months evaluation, complete healing was evident in 780 patients (77.7%). Resting anal tone (77.1 ± 18.9 mmHg) was significantly lower from baseline (P < 0.0001) and from 1-month value (P = 0.0008). Thirty-nine not healed patients underwent lateral internal sphincterotomy, and 184 were re-treated with 50 UI of botulinum toxin. In these patients, the healing rate was 93.9% (171 patients). Dose and injection site of toxin correlates with healing rate. There were no relapses during an average of about 71 months. CONCLUSION Our data show that injection of botulinum toxin into the internal anal sphincter is a safe and effective alternative to surgery in patients with chronic anal fissure.

Abstract
Introduction: Surgery for chronic anal fissure is challenging for every proctologist. Solving the pain by guaranteeing rapid and effective healing is the objective, but what is the price to pay today in functional terms? Though this result is nowadays partially achievable through interventions that include the execution of an internal sphincterotomy among the procedures, it is necessary to underline the high rate of patients who can present faecal incontinence. The aim of this study is to explore the effectiveness of scanner-assisted CO2 laser fissurectomy. Methods: From April 2021 to September 2021, all consecutive patients who affected by chronic anal fissure suitable for surgery, meeting the inclusion and exclusion criteria, were evaluated. All planned data were recorded before surgery, then at 24 h, 1 week, and 1 month follow-up. A scanner-assisted CO2 laser was used in this study to achieve a smooth and dried wound with a minimal tissue thermal damage, to ensure good postsurgical pain control, rapid and functional, elastic and stable healing, and to prevent potential relapses. Paracetamol 1 g every 8 h was prescribed for the first 24 h and then continued according to each patient's need. Ketorolac 15 mg was prescribed as rescue. Results: Mean pain intensity ≤3, considered as the principal endpoint, was recorded in 26 out of the 29 patients who enrolled in the study with a final success rate of 89.7% at 1-month follow-up. Pain and anal itching showed a statistically significant reduction while bleeding, burning, and maximum pain, and REALIS score showed a reduction too at the end of the follow-up period. Reepithelisation proved to be extremely fast and effective: 22 of 29 (75.9%) showed a complete healing and 5 showed a partial reepithelisation at 1-month follow-up. Discussion: Outcomes of this study showed that it is undoubtedly necessary to change the surgical approach in case of anal fissure. The internal sphincterotomy procedure must be most of all questioned, where the availability of cutting-edge technological tools must be avoided and offered only in selected cases. Scanner-assisted CO2 laser showed great results in terms of pain control and wound healing, secondary to an extremely precise ablation, vaporisation, and debridement procedures with minimal lateral thermal damage.

Abstract
We report the synthesis and characterization of a photoactive nitric oxide (NO) releasing nanoparticle (NP) by encapsulation of the NO donor tert-dodecane S-nitrosothiol (tDodSNO) into a co-polymer of styrene and maleic anhydride (SMA) to afford SMA-tDodSNO. Encapsulation did not affect tDodSNO's stability or NO release profile, but imparted water solubility and protection from degradation reactions with glutathione. Under photoactivation the NP acted as a potent NO donor, with photoactivation acting as a switch to induce localized vasodilation in aortic rings (EC50* 660 nM at 2700 W/m2) and cause vascular hyperpermeability in mesenteric beds (8-fold increase in dye uptake at 1 µM SMA-tDodSNO with 460 W/m2 photoactivation). The NP was markedly superior as a photoactive NO donor in comparison to the S-nitrosothiols GSNO and SNAP, which are commonly used in experimental studies, as well as sodium nitroprusside, a clinically used vasodilator. Future development of this NP may find wide ranging therapeutic applications for treating cardiovascular disease and other disorders related to NO signaling, as well as enhancing macromolecular drug delivery to target organs through selective hyperpermeability. Supporting information describing the biophysical characterization of SMA-tDodSNO is supplied in an accompanying Data in Brief article (Alimoradi et al., doi: 10.1016/j.dib.2018.10.149).

Abstract
RESUMO Objetivo: avaliar os resultados de longo prazo da correção de fissuras anais crônicas em pacientes sem hipertonia anal usando a técnica de anoplastia com o plicoma sentinela. Métodos: estudo prospectivo de pacientes com fissura anal crônica refratários ao tratamento conservador e sem hipertonia anal, submetidos à operação de anoplastia com utilização do plicoma anal para cobrir a área cruenta. Foi confirmada a ausência de hipertonia anal através do toque retal e da eletromanometria. Foi aplicado um questionário de dor visual e o escore de incontinência fecal da Cleveland Clinic, antes e após a cirurgia. Resultados: quinze pacientes com fissura anal crônica foram acompanhados por um período médio de 29 meses (12 a 56). A média de idade foi 41 anos (29 a 69) e a duração dos sintomas variou entre seis meses e cinco anos. A cicatrização ocorreu entre três e seis semanas para 13 pacientes (86,7%). Os outros dois pacientes foram submetidos a desbridamento e nova anoplastia, com sucesso. Em nenhum paciente ocorreu necrose do plicoma ou estenose anal. O escore de incontinência anal não se alterou após o procedimento e todos os pacientes referiram melhora da dor. Após 12 meses de seguimento, nenhum paciente apresentou recorrência ou incontinência anal e 93,3% (14/15) dos pacientes responderam estar muito satisfeitos. Conclusão: fissurectomia e anoplastia com o uso do plicoma sentinela é uma técnica segura que resulta em melhora da dor sem alterações da continência fecal e com altas taxas de satisfação.

Abstract
PURPOSE OF REVIEW To overview the current medical literature on the efficacy of botulism toxin treatment (BTX-A) for lower gastrointestinal disorders (GIT). RECENT FINDINGS BTX-A was found to have a short-term efficacy for the treatment of dyssynergic defecation. Surgical treatment was found to be more effective than BTX-A for the healing of chronic anal fissures, and BTX-A can be considered when surgery is undesirable. Data regarding the effects of BTX-A injection for the treatment of chronic anal pain is limited. Beneficial effects were observed only in a minority of patients. BTX-A treatment was found to be effective for the treatment of obstructive symptoms after surgery for Hirsprung's disease as well as for the treatment of internal anal sphincter achalasia. BTX-A treatment has a short-term efficacy and is safe. Further research is still needed in order to establish the exact place of BTX-A treatment of lower GIT disorders.

Abstract
Myoxinol is a complex of oligopeptides obtained from the seeds of Hibiscus esculentus used in cosmetic as natural alternative to botulin toxin. The aim of the study was to evaluate the safety and effectiveness of local myoxinol for the treatment of acute anal fissure. All the consecutive patients with acute fissure treated from January to June 2014 underwent 30 days of topical treatment (twice/day) with a mioxinol based ointment. Pain, symptomatic relief, fissure healing and re-epithelization, 1-year recurrence rate, subjective satisfaction and need for further treatments were evaluated. During the study period 157 patients were eligible for data analysis (91 males: 58%; mean age 38 years: range 17-83). Median anal pain score was 7.1 pre-treatment and 1.7 and 0.9 after 30 days and 12 months from treatment, respectively (p: 0.0001). After the treatment period complete healing was achieved in 103 patients (65.5%), relevant improvement in 31 (20%) and no improvement in 21 patients (13.5%). Overall efficacy rate was 85.5%. A significant difference was reported considering patients with pre-treatment VAS between 1-5 and 6-10 (p: 0.004). Twenty-nine patients (18.5%) required further treatments. Hydrolyzed Hibiscus esculentus extract was proven to be an effective and well-tolerated topical treatment for acute fissure, with a high healing rate, a significant reduction of pain and a low 1-year recurrence rate.

Abstract
Botulinum toxin A inhibits neuromuscular transmission. It has become a drug with many indications. The range of clinical applications has grown to encompass several neurological and non-neurological conditions. One of the most recent achievements in the field is the observation that botulinum toxin A provides benefit in diseases of the gastrointestinal tract. Although toxin blocks cholinergic nerve endings in the autonomic nervous system, it has also been shown that it does not block non-adrenergic non-cholinergic responses mediated by nitric oxide. This has promoted further interest in using botulinum toxin A as a treatment for overactive smooth muscles and sphincters. The introduction of this therapy has made the treatment of several clinical conditions easier, in the outpatient setting, at a lower cost and without permanent complications. This review presents current data on the use of botulinum toxin A in the treatment of pathological conditions of the gastrointestinal tract.

Abstract
AIM Nitric oxide donors, such as isosorbide dinitrate ointment (ISDN), are considered as first-choice agents in the treatment of chronic anal fissure. Injection with botulinum toxin A in the internal anal sphincter is often used as a second-line therapy, although it may give better results and fewer side effects than nitric oxide donors. The aim of this randomized clinical trial was to investigate whether botulinum toxin A (Dysport) is more effective than ISDN in the primary treatment of chronic anal fissure. METHOD From April 2005 until October 2009, 60 patients (32 men) with a median age of 42 (25-82) years were randomized to receive either ISDN 10 mg/ml (1%) (n = 33) or injection with 60 units of Dysport (n = 27). The primary end-point was the percentage of complete fissure healing after 8 weeks. RESULTS After a median of 9 weeks complete fissure healing was noted in 18 of 27 patients in the Dysport group and in 11 of 33 patients in the ISDN group (P = 0.010). Absolute improvement of pain scores after 9 weeks was similar in both groups (P = 0.733). Patients treated with Dysport had fewer side effects than patients treated with ISDN (P = 0.028). Of the patients with a healed fissure, 28% of the Dysport group and 50% of the ISDN group had a recurrence within 1 year (P = 0.286; hazard ratio 2.08; 95% CI = 0.54-7.97). CONCLUSION Dysport is more effective than ISDN ointment and has fewer side effects in the primary treatment of chronic anal fissure. The recurrence rate within 1 year in both treatment groups is high.

Abstract
Chronic anal fissure is one of the most frequent anorectal disorders. Symptoms vary but typically include bright red rectal bleeding, itching and discomfort or pain during and after defecation. Treatment has undergone a transformation in recent years from surgical to medical, all approaches sharing the goal of reducing the spasm.According to the researched treatment guidelines and the experience at the “University Clinical Center Mother Teresa†(Clinic of Gastroenterohepatology and Clinic of Abdominal Surgery) in Skopje, Macedonia, we propose the following algorithm for treatment of chronic anal fissure in three steps: from topical nifedipine + lidocaine cream (first-line) to second course of nifedipine + lidocaine cream or digital anal dilatation or botulinum toxin type A injection (second-line) to lateral internal sphincterotomy (third-line).The proposed treatment algorithm allows patients to start with the least invasive treatment. There is no doubt that patients are willing to try less invasive modalities with the hope of avoiding surgery, with its risk of permanent disability. It should be up to the patients to decide which treatment they prefer. Although chemical sphincterotomy is less successful from lateral internal sphincterotomy, the algorithm allows feasibility, efficacy and cost-effectiveness, as well as risk reduction for surgical morbidity.

Abstract
Anal fissure is a split in the lining of the distal anal canal. Lateral internal sphincterotomy remains the gold standard for treatment of anal fissure. Although technique is simple and effective, a drawback of this surgical procedure is its potential to cause minor but some times permanent alteration in rectal continence. Conservative approaches (such as topical application of ointment or botulinum toxin injections) have been proposed in order to treat this condition without any risk of permanent injury of the internal anal sphincter. These treatments are effective in a large number of patients. Furthermore, with the ready availability of medical therapies to induce healing of anal fissure, the risk of a first-line surgical approach is difficult to justify. The conservative treatments have a lower cost than surgery. Moreover, evaluation of the actual costs of each therapeutic option is important especially in times of economic crisis and downsizing of health spending.

Mapel DW, Schum M, Von Worley A. The epidemiology and treatment of anal fissures in a population-based cohort. BMC Gastroenterol 2014; 14:129. [PMID: 25027411 PMCID: PMC4109752 DOI: 10.1186/1471-230x-14-129] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2014] [Accepted: 07/07/2014] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND Anal fissure (AF) is regarded as a common problem, but there are no published epidemiologic data, nor information on current treatment. The purpose of this study was to examine the incidence, associated comorbidities, and treatment of AF in a population-based cohort. METHODS We conducted a retrospective analysis of all persons who were enrolled in one large regional managed care system and treated for AF during calendar years 2005-2011. All persons aged 6 years or older who had a clinic, hospitalization, or surgical procedure associated with AF were identified from utilization data. To identify comorbidities associated with AF, each case was matched by age and gender to 3 controls. RESULTS There were 1,243 AF cases, including 721 (58%) females and 522 (42%) males; 150 (12%) of the cases occurred in children aged 6-17 years. The overall annual incidence was 0.11% (1.1 cases per 1000 person-years), but ranged widely by age [0.05% in patients 6-17 years to 0.18% in patients 25-34 years]. The incidence also varied by sex, and was significantly higher among females 12-24 years, and among males 55-64 years (P < 0.001). Comorbidities associated with AF included chronic constipation (prevalence 14.2% vs 3.6%), hypothyroidism (14.7% vs 10.4%), obesity (13.0% vs 7.7%), and solid tumors without metastasis (5.2% vs 3.7%) (P < 0.001 for all comparisons). A total of 448 were dispensed a topical prescription medication, 31 had botulinum toxin injection, and only 13 had lateral internal sphincterotomy. CONCLUSIONS AF is a common clinical problem, and the incidence varies substantially by age and sex. Constipation, obesity, and hypothyroidism are associated comorbidities. Most patients are prescribed topical treatments, although it appears that many prescriptions are never filled. Surgical interventions for AF including botulinum toxin and lateral internal sphincterotomy are uncommon.

Abstract
OBJECTIVE To assess the effectiveness of different modes of treatment of chronic anal fissure as regards improvement of symptoms and complications. METHODS This prospective study included 129 consecutive patients with chronic anal fissures presented to the Surgical Outpatients' Department of Islam Teaching Hospital Sialkot, Pakistan; from September 2010 to November 2012. Patients were distributed in three groups. In "OBG group", patients had attended Gynae/Obs OPD and got treated and were then referred to surgical OPD for failure of treatment or recurrence. Patients who presented with history of treatment by GPs were included in "GP Group" "SGR Group" included those who directly reported to surgical OPD for treatment. Patients were managed both pharmacologically as OPD patients and surgically as admitted patients. Patients were instructed to apply small amounts of 0.2% GTN paste in soft white paraffin, to the anoderm with finger tips three times a day. Patients were evaluated at two-week intervals and at each visit the symptoms control, adverse effects and fissure status were recorded. If there was symptomatic relief or the fissure healing was in progress, the treatment was continued for a total duration of eight weeks. Operated patients were nursed in wards after surgery i.e Internal Anal Sphicterotomy. They were advised to report to OPD weekly for one month or earlier if they experienced any symptoms suggestive of complications. Patients were declared cured in case of complete symptomatic relief with fissure healing. Success, failure and associated problems were recorded and analysed to get results. RESULTS This study included 129 patients who could be followed up for a minimum of three months. These patients were referred by gynaecologist i.e. 22 (17%) for treatment failure while 5 patients with wrong diagnosis were not included in statistical analysis; similarly 41 (32%) patients were referred by general practitioners and 9 patients with wrong diagnosis were excluded. Sixty six patients i.e. 51% were those who directly reported to surgical OPD and had no previous treatment. With surgical treatment, pain, bleeding per rectum and constipation showed significant improvement as compared to GTN ointment application. Fissure healing was 100% in surgical group as compared to 74% in medical group. Complications were recorded and were found to be headache with medical treatment; while the most feared complication with surgical treatment i.e. permanent incontinence was not encountered in our study. CONCLUSION Topical glyceryl trinitrate is economical, has a good healing rate, and faecal incontinence has not been reported. Its effectiveness, however, depends on patients' compliance which may be poor in view of associated headaches and a local burning sensation. It is first line of treatment for anal fissure but lateral internal sphincterotomy is superior, more effective and curative than the chemical sphincterotomy. Surgery is reserved for people with anal fissure who have tried medical therapy for at least one to three months but failed.

Abstract
Anal fissure is a common anorectal disorder resulting in anal pain and bleeding. Fissures can either heal spontaneously and be classified as acute, or persist for 6 or more weeks and be classified as chronic, ultimately necessitating treatment. Anal stenosis is a challenging problem most commonly resulting from trauma, such as excisional hemorrhoidectomy. This frustrating issue for the patient is equally as challenging to the surgeon. This article reviews these 2 anorectal disorders, covering their etiology, mechanism of disease, diagnosis, and algorithm of management.

Abstract
BACKGROUND Lateral internal sphincterotomy has been proven highly effective in curing anal fissure but with a high incidence of postoperative incontinence. OBJECTIVE We compared conventional lateral internal sphincterotomy, V-Y advancement flap, and combined tailored lateral internal sphincterotomy with V-Y advancement flap in treating anal fissure. PATIENTS Consecutive patients treated for anal fissure at our colorectal unit were evaluated for inclusion. Participants were randomly allocated to receive conventional sphincterotomy (GI), V-Y advancement flap (GII), or combined tailored lateral sphincterotomy with V-Y advancement l flap (GIII). MAIN OUTCOME MEASURES The primary outcome measure was the incontinence rate; secondary outcomes included healing rate, operative time, anal manometery, and recurrence rate. RESULTS One hundred fifty patients with chronic anal fissure were randomized. Healing rate after 1 year was 84% in GI, 48% in GII, and 94% in GIII, respectively (P = 0.001). The recurrence rate was 4% in G1, 22% in GII, and 2% in GIII (P = 0.01). Incontinence rate was 14% in GI, 0% in GII, and 2% in GIII (P = 0.03). CONCLUSION Although all three procedures are simple and easy to perform, tailored lateral internal sphincterotomy with V-YF appears to produce the greatest healing rate, with the fewest complications and less rate of recurrence.

Abstract
AIM The aim of the study was to determine the long-term outcome, recurrence rate and faecal incontinence score after fissurectomy for chronic anal fissure (CAF) not responding to conservative treatment. METHOD Fifty-three consecutive patients (29 women) who underwent fissurectomy for a medically resistant CAF between 1998 and 2005 were included in the study. At a minimum follow-up of 5 years a standardized questionnaire was sent to all patients, assessing recurrence, satisfaction with the operation (on a scale of 0-10) and faecal continence (Vaizey score, 0-24). The patients were compared with a control group of 50 healthy volunteers, matched for sex and age, who had never undergone anal surgery. RESULTS Forty-three (81%) patients (25 women) returned the questionnaire. The mean age was 40 (SD 12.1) years and median follow up was 8.2 (5.5-12.2) years. Five patients had a recurrent CAF (11.6%). Ninety per cent of patients would have consented to the operation again if necessary. The mean Vaizey score at follow-up was 2.5 (SD ± 4.2). The mean Vaizey score of the four patients who had had a previous lateral sphincterotomy was 3.8 and for the eight patients who had reported a continence disturbance before fissurectomy it was 8.3. The mean Vaizey score of the 31 patients who were continent before fissurectomy was 0.8 compared with 0.4 in the control group (P = 0.9). CONCLUSION At 5 years or more fissurectomy for medically resistant CAF is effective with a low recurrence rate and minimal influence on continence.

Abstract
AIM To study the effect of botulinum toxin in patients with chronic anal fissure after biliopancreatic diversion (BPD) for severe obesity. METHODS Fifty-nine symptomatic adults with chronic anal fissure developed after BPD were enrolled in an open label study. The outcome was evaluated clinically and by comparing the pressure of the anal sphincters before and after treatment. All data were analyzed in univariate and multivariate analysis. RESULTS Two months after treatment, 65.4% of the patients had a healing scar. Only one patient had mild incontinence to flatus that lasted 3 wk after treatment, but this disappeared spontaneously. In the multivariate analysis of the data, two registered months after the treatment, sex (P = 0.01), baseline resting anal pressure (P = 0.02) and resting anal pressure 2 mo after treatment (P < 0.0001) were significantly related to healing rate. CONCLUSION Botulinum toxin, despite worse results than in non-obese individuals, appears the best alternative to surgery for this group of patients with a high risk of incontinence.

Abstract
OBJECTIVE A double-blind randomized clinical trial to compare topical diltiazem with botulinum toxin A (BTA) in the treatment of chronic anal fissure. BACKGROUND Chronic anal fissures remain a challenging condition. Topical diltiazem and BTA are promising agents in the treatment of anal fissure. As to date diltiazem and BTA were never compared in a solid randomized trial, which is the purpose of this study. METHODS One hundred thirty-four patients were randomized to receive either diltiazem cream and placebo injection or BTA injection and placebo cream. The primary end point was fissure healing after 3 months. RESULTS After 3 months healing of the fissure was noted in 32 of 74 (43%) patients in the diltiazem group and 26 of 60 (43%) patients in the BTA group. Reduction >50% in mean pain score was noted in 58 of 74 (78%) patients in the diltiazem group and 49 of 60 (82%) patients in the BTA group. Perianal itching was the only side effect reported and was noted in 15% of patients in the diltiazem group, and this difference was statistically significant (P = 0.012). CONCLUSIONS BTA yields higher healing rates in the short term, though after 3 months diltiazem and BTA resulted in equal healing rates. Also no significant difference in pain reduction was observed for both treatments. This study shows no significant advantage of one treatment compared to the other. This randomized clinical trial is registered by the Dutch Trial Register as NTR1012.

Abstract
INTRODUCTION It is becoming increasingly clear that many diseases are characterized or associated with perturbations in nitric oxide (NO) production/signaling. Therapeutics or strategies designed to restore normal NO homeostasis will likely have broad application and utility in human health. This highly complex and multi-step pathway for NO production and subsequent target activation provides many steps in the endogenous pathway that may be useful targets for drug development. Important therapeutic areas for NO-based therapies are inflammatory disorders, cardiovascular diseases, erectile dysfunction and metabolic disorders. AREAS COVERED The following review will discuss the endogenous NO pathway, highlight the current market and indications for NO-based therapeutics, as well as identify pathway targets currently under drug development. Each step along the NO pathway will be discussed including exogenous sources of NO, use of precursors to promote NO production and downstream pathways affected by NO production with advantages and disadvantages highlighted for each. EXPERT OPINION Development of NO-based therapeutics is and will continue to be a major focus of biotech and pharmaceutical companies. Understanding and utilizing dietary and nutritional strategies to restore NO homeostasis could allow for safer, quicker marketing of products that may be just as efficacious as drugs designed against specific targets.

Abstract
Aim. The purpose of this study was to investigate whether endoanal ultrasonographic findings could better characterize chronic anal fissures, mostly in those patients with persistent and recurrent disease after medical treatment. Methods. Between January 2004 and April 2010, patients referred to our departments suspected for anal fissure were considered in a database. Physical examination and anoscopy confirmed the diagnosis of anal fissure in 543 patients. Chronicity was defined on the basis of morphological features of the fissure and mainly on its persistence or recurrence after medical therapy. Moreover, 172 out of 543 patients were selected with respect to the inclusion criteria and submitted to endoanal ultrasonography. Results. Seventeen out of 172 were anterior fissures (9.8%) and 155 posterior (90.2%). In 112 (65.1%) out of 172 patients submitted to endoanal ultrasonography, an associated chronic abscess was demonstrated, with expression of 91 intersphincteric and 21 low transphincteric fistulas, respectively. According to clinical data as well as comorbidities and previous surgery, there were no significant differences between patients with associated abscess and those with only chronic anal fissure. Conclusion. The authors assume that chronic fissures may persist because of hiding sepsis in the anal canal and that chronic anal fissure might be the clinical and pathological expression of a coexisting intersphincteric or low transphincteric fistula, and the ultrasonographic findings strongly support this theory.

Abstract
Anal fissure is one of the most common and painful proctologic diseases. Its treatment has long been discussed and several different therapeutic options have been proposed. In the last decades, the understanding of its pathophysiology has led to a progressive reduction of invasive and potentially invalidating treatments in favor of conservative treatment based on anal sphincter muscle relaxation. Despite some systematic reviews and an American position statement, there is ongoing debate about the best treatment for anal fissure. This review is aimed at identifying the best treatment option drawing on evidence-based medicine and on the expert advice of 6 colorectal surgeons with extensive experience in this field in order to produce an Italian position statement for anal fissures. While there is little chance of a cure with conservative behavioral therapy, medical treatment with calcium channel blockers, diltiazem and nifepidine or glyceryl trinitrate, had a considerable success rate ranging from 50 to 90%. Use of 0.4% glyceryl trinitrate in standardized fashion seems to have the best results despite a higher percentage of headache, while the use of botulinum toxin had inconsistent results. Nonresponding patients should undergo lateral internal sphincterotomy. The risk of incontinence after this procedure seems to have been overemphasized in the past. Only a carefully selected group of patients, without anal hypertonia, could benefit from anoplasty.

Abstract
PURPOSE Chemical sphincterotomy (CS) is routinely applied in order to avoid the irreversible anal incontinence associated with the surgical treatment of chronic anal fissure (CAF). However, CS has a lower cure rate than surgery. We developed a screening test (using anal manometry) to separate those patients that are unlikely to benefit from CS and should undergo a more aggressive treatment. METHODS Changes in pressure both at rest and during voluntary contraction of the anal sphincter in 187 patients with chronic anal fissure and 25 healthy subjects (control group) of both sexes were measured. Patients were then sequentially treated (1:1:1) with botulin toxin injections (TOX) (n = 63) or ointments of either nitroglycerine (NTG) (n = 65) or diltiazem (DTZ) (n = 59) for 2 months. The cure rate (overall and for each treatment group) and its relationship with changes in anal pressure were determined. RESULTS The overall cure rate was 53% (NTG = 54%, DTZ = 53% and TOX = 51%). Healing was not related to differences in resting or voluntary contraction pressure. However, the probability of healing was associated with an increase in the percentage change between resting and squeeze pressure (PI index) higher than 150% (190 +/- 122), similar to that of the control subjects (200 +/- 115). Failure of CS was observed in patients with a lower PI (114 +/- 77). CONCLUSIONS The ratio resting/voluntary contraction pressure may be predictive of healing in CAF, thus allowing the selection of patients at high risk of failure of conservative treatment.

Abstract
INTRODUCTION It was suggested that anal advancement flap be used to treat patients with chronic anal fissures that have failed medical management and have a low-pressure sphincter complex. We wished to assess anal advancement flap as a treatment for all chronic anal fissures. METHODS All patients with chronic anal fissures regardless of their previous management underwent V-Y advancement flap. Patient demographics, symptom duration, previous treatments, short-term postoperative outcome and long-term follow-up were recorded. RESULTS Fifty-four consecutive patients, median age 39 years (22-66), underwent a V-Y advancement flap over a 7-year period; 34 were men. Duration of symptoms ranged from 2 to 36 months with a median of 8 months. Forty-two patients (78%) had failed a previous therapy: glyceryl trinitrate (GTN) (25), GTN and diltiazem (16) and lateral sphincterotomy (one). Wound dehiscence occurred in three patients of which only one required a surgical intervention. On follow-up at 6 months, all but one patient had a healed wound and was asymptomatic. CONCLUSIONS We have shown excellent rates of healing of chronic anal fissures treated with a V-Y advancement flap regardless of sphincter pressures, previous treatment and symptom chronicity. These results show the technique can be applied to all chronic fissures with success and used as a primary therapy.

Abstract
AIM To compare the results of subcutaneous internal lateral sphincterotomy under local anesthesia and nitroglycerin ointment treatments in acute and chronic anal fissures. METHODS This was a comparative, prospective study of 340 patients of acute and chronic anal fissure. The patients voluntarily opted either for the surgical procedure under local anesthesia, or the nitroglycerin treatment. All the patients were followed with regular checkups and complaints were documented. RESULTS Except for 1.75% patients having bleeding/hematoma formation, and with a dropout of 2.60% patients, no failure, recurrence or long term complications like incontinence, were observed in patients who underwent subcutaneous internal lateral sphincterotomy after a mean follow up of 28 months. With surgical treatment pain, bleeding per rectum and constipation showed significant improvement as compared to nitroglycerin treatment. Fissure healing was 100% in surgical group as compared to 56.90% in medical group (P=0.000, odds ratio=344.6). Nitroglycerin was equally effective in acute and chronic fissures (P=0.096). CONCLUSION Subcutaneous internal lateral sphincterotomy under local anesthesia is more curative, easy and safe, in the hands of a beginner as well as an experienced surgeon, with highest patient satisfaction, and should be considered as the first line of therapy in both chronic and resistant/recurrent acute anal fissures.

Abstract
Anorectal disorders like haemorrhoids, rectal prolapse, anal fissures, peri-anal fistulae and sexually transmitted diseases are bothersome benign conditions that warrant special attention. They, however, can all be diagnosed by inspection or proctoscopy (sexually transmitted proctitis). Constipation can play an underlying role in haemorrhoids, rectal prolapse and anal fissures, and it is important to treat these conditions in order to avoid recurrences. Haemorrhoids and anal fissures are generally treated conservatively and surgery is seldom required. Rectal prolapse and cryptoglandular peri-anal fistulae are treated surgically. In a recurrent peri-anal fistula, the fistular tract needs to be visualised with anal ultrasound or magnetic resonance imaging (MRI). There are different techniques available for this evaluation, and care must be taken not to damage the anal sphincter. Peri-anal fistulae in Crohn's disease are treated conservatively and surgery is only required in cases with abscesses. Sexually transmitted proctitis needs to be adequately recognised and treated according to the infectious agent.

Abstract
INTRODUCTION Chronic anal fissure is a common benign disorder; for this condition, lateral internal sphincterotomy is the "gold standard" of treatment. Alternative medical treatments have not proven to be as effective as left lateral internal sphincterotomy. AIM This randomized trial was designed to compare the use of 0.25% glyceryl trinitrate ointment and anal cryothermal dilators with the use of 0.4% glyceryl trinitrate ointment alone in the treatment of chronic anal fissures. METHODS Between 1 June 2006 and 31 December 2007, 60 consecutive patients who were suffering from chronic anal fissures were randomized into two groups. The patients in group A (n = 30) were treated with 0.25% glyceryl trinitrate ointment and anal cryothermal dilators twice daily, and those in group B (n = 30) were treated with 0.4% glyceryl trinitrate ointment alone twice daily. The treatment was administered to the patients in each group for 6 weeks, and all patients were examined 7 weeks after the start of the trial. RESULTS Prior to treatment, the symptoms and the measurements of anal pressure were similar in both groups. At 7 weeks, the maximum resting pressure was significantly lower in group A (P < 0.05), in which 86.6% of the patients were asymptomatic in comparison with 73.3% of the patients in group B. After 1 year of follow-up, 25 patients (83.3%) in group A and 18 patients (60%) in group B presented no recurrence of symptoms (P < 0.05) CONCLUSIONS Treatment of chronic anal fissures with 0.25% glyceryl trinitrate ointment and anal cryothermal dilators was more effective than the administration of 0.4% glyceryl trinitrate ointment alone.

Abstract
BACKGROUND A proportion of patients with chronic anal fissure have persistent symptoms and pathology despite optimum conservative therapies. Lateral anal sphincterotomy, the standard surgical treatment, is associated with functional compromise in a minority of patients. Sphincter-sparing anoplasty has been advocated as an alternative procedure for those with "low pressure" sphincters. The aim of this study was to determine the efficacy of simple cutaneous advancement flap anoplasty (SCAFA) when applied to consecutive patients with chronic anal fissure irrespective of anal tone and the patient's gender. METHOD This was a prospective outcome study of 51 consecutive patients treated with SCAFA over a 6.5-year period. RESULTS Surgery was well tolerated. There were three (5.9%) early flap dehiscences, all of which were treated with repeat SCAFA, and one of those three patients remained symptomatic at 2 months. All fissures healed in the short term. Three other patients subsequently developed fissures at sites remote from the original pathology. Continence was unaffected by the procedure. CONCLUSIONS Simple cutaneous advancement flap anoplasty should be considered as a first-line surgical treatment of chronic anal fissure, irrespective of patient gender and anal tone.

Abstract
OBJECTIVE To analyse the diagnostic performance of the primary care (PC) doctor in benign anal diseases. DESIGN Cross-sectional study including patients referred to our clinic from PC with the diagnosis of clinical conditions pertaining to benign anal diseases between 1st June and 31st December 2007. The diagnosis established by the PC doctor was compared with that of 2 medical specialists in general and digestive diseases surgery. SETTING Department of General Surgery and Digestive Diseases. Castellon General Hospital. PARTICIPANTS Patients diagnosed with a benign anal disease in PC and referred to our department. MEASUREMENTS The sensitivity, specificity and kappa index was calculated for each disease. RESULTS A total of 105 patients were included. The diagnoses were: 65 haemorrhoids, 13 fissures, 8 fistulas, 7 abscesses, 4 pilonidal cysts, and 8 other diagnoses. A physical examination was carried out on 61 patients and 19 had a rectal examination. In AE, 44 haemorrhoids, 20 fissures, 9 pilonidal cysts were diagnosed and there were 16 other diagnoses. For haemorrhoids the sensitivity was 90.9%, the specificity 59%, and the kappa index was 0.5. For a fistula, it was 43.8%, 98.9% and 0.5, respectively and for a fissure, 15%, 88.2% and 0.04. The physical examination improved all these results. CONCLUSIONS The diagnostic performance of benign anal diseases in PC is insufficient. A good physical examination and improved training in these diseases could possibly improve these results.

Abstract
BACKGROUND The aim of the study was to evaluate the efficacy of botulinum toxin injection in the treatment of recurrent anal fissure following lateral internal sphincterotomy. METHODS Eighty patients were treated with botulinum toxin (30 units Botox or 90 units Dysport), injected into two sites of the internal sphincter. Clinical and manometric results were recorded before and after treatment. If symptoms persisted at 2 months, the examiners could decide to re-treat the patient. The same preparation of serotype A of botulinum neurotoxin was used for reinjection. RESULTS One month after injection there was complete healing in 54 patients (68 per cent). Eight patients (10 per cent) reported mild incontinence of flatus that had disappeared spontaneously within 2 months. At 2 months, 59 patients (74 per cent) had a healing scar. After reinjection, 11 of 21 re-treated patients reported mild incontinence to flatus that lasted for a few weeks and resolved spontaneously. Anorectal manometry at 1 month demonstrated a significant reduction in both resting anal pressure and maximum voluntary squeeze pressure (P < 0.001). There were no relapses during a mean value of 57.9 months of follow-up. CONCLUSION Botulinum toxin is efficacious in patients with recurrent anal fissure following lateral internal sphincterotomy.

Abstract
OBJECTIVE Keyhole deformity is frequently encountered after posterior internal sphincterotomy but may be observed after lateral internal sphincterotomy or in patients without any history of previous anal surgery. The aim of the present study is to emphasize the surgical significance of this entity and discuss the possible strategies in the treatment of the deformity. MATERIAL AND METHODS Patients in whom keyhole deformity developed after surgical or conservative treatment applied for chronic anal fissure in our clinic and patients referred from other centers were recruited. RESULTS Nine-hundred twenty-six patients were treated for chronic anal fissure. A hundred of these patients directly underwent lateral internal sphincterotomy. The remaining 826 patients initially received conservative management, and 676 of them eventually underwent lateral internal sphincterotomy. In total, 15 patients were diagnosed to have significant keyhole deformity. Initially, all patients received conservative treatment for keyhole deformity, which was successful in two patients. Of the 13 patients in whom conservative management failed, nine underwent advancement flap reconstruction and the remaining four diamond flap reconstruction. CONCLUSION Keyhole deformity is occasionally seen as a late complication of chronic anal fissure and may be well tolerated by the patients without any well-defined symptoms. The treatment strategy is directed toward the degree of functional alteration.

Abstract
Nearly all chronic anal fissures occur in the posterior midline of the anal canal. However, some of them are in the anterior midline and are rarely double or in the lateral anal walls. The aim of this study was to determine if the clinical, manometric and endosonographic characteristics in patients with chronic anal fissure varied according to topography of the fissure. The patients included in this prospective study were divided according to a fissure site in posterior midline location (Group A, n = 84) and anterior midline location (Group B, n = 30). No differences were found regarding clinical data except that anterior fissures were more common in females. Mean maximal anal resting pressure and internal anal sphincter thickness was higher in Group A. However, these differences were not statistically significant. We found correlation between mean maximal anal resting pressure and internal anal sphincter thickness in patients suffering from anterior chronic anal fissure.

Abstract
Since its introduction for the treatment of strabismus, botulinum toxin (BoNT) has been increasingly used in the treatment of several disorders with excessive or inappropriate muscle contractions. The therapeutic effects of BoNT occur through the temporary chemodenervation caused by the injection into the local target muscle or skin. Modulation of muscle relaxation may be achieved by varying the dose of BoNT solution injected; most adverse effects are transient. Indeed, botulinum neurotoxin has been used to selectively weaken the internal anal sphincter as a treatment for chronic anal fissure in several randomized, controlled trials and open-label studies. The use of botulinum neurotoxin seems to be an effective and safe approach for the treatment of chronic anal fissure, particularly in patients at high risk for incontinence.

Abstract
BACKGROUND Hypertonicity of the internal anal sphincter (IAS) appears to be involved in the pathogenesis of anal fissure. The relaxant effects of sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, on isolated human IAS were investigated. METHODS The efficacy (maximal effect, E(max)) and potency (-log IC(50), where IC(50) is half-maximal inhibitory concentration) of the PDE5 inhibitors, sildenafil and zaprinast, and of nitric oxide donors, sodium nitroprusside and glyceryl trinitrate, as relaxants of histamine (0.1 mmol/l)-induced tone were examined in IAS strips under isometric contraction. The presence of PDE5 isoenzymes and changes in intracellular calcium and cyclic nucleotide levels in IAS muscle were tested by real-time reverse transcriptase-polymerase chain reaction, epifluorescence microscopy and enzyme immunoassay respectively. RESULTS Sildenafil produced a concentration-related inhibition of the mean(s.e.m.) histamine-induced tone (E(max) 83(2) per cent, - log IC(50) 7.04(0.05); n = 12). Zaprinast produced relaxation to similar degree, but with lower potency. Nitric oxide donors also relaxed IAS. Sildenafil (1 micromol/l) produced a 1.8-fold increase in guanosine 3',5'-cyclic monophosphate content, with no change in adenosine 3',5'-cyclic monophosphate levels. Sildenafil markedly depressed the peak intracellular calcium increase evoked by histamine. PDE5A1, PDE5A2 and PDE5A3 transcripts were expressed in IAS muscle. CONCLUSION Sildenafil relaxes the augmented tone of human IAS in vitro. These results support the potential use of this PDE5 inhibitor in the treatment of chronic anal fissure.

Abstract
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.

Abstract
Anal fissure management has rapidly progressed in the last 15 years as our understanding of fissure pathophysiology has developed. All methods of treatment aim to reduce the anal sphincter spasm associated with chronic anal fissures. Surgical techniques have been used for over 100 years with success. Lateral internal sphincterotomy remains the surgical treatment of choice for many practitioners. Postoperative impairment of continence remains controversial. Recently, less invasive methods of treatment have been explored. Topical nitrates, calcium channel blockers and botulinum toxin are established treatments. These and other non-surgical treatments are described in this review. Various guidelines and treatment algorithms for anal fissure are also discussed.

Abstract
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. Hypertonia of the IAS was found in 84 (68%) patients. The mean maximum IAS thickness was 3.6 +/- 0.76 mm (1.6-5.5). An abnormally thick IAS, adjusted by age, was observed in 113 (91.1%) patients. We found no correlation between resting pressure and IAS thickness (r = 0.074; p = 0.41). At 8 weeks, 52 patients (42%) had healed with complete symptoms resolution. No statistically significant differences were observed when clinical features and manometric and endosonographic findings were compared between healing and no-healing fissures. CONCLUSION The majority of patients with chronic anal fissure present an abnormally thick IAS. Clinical, manometric and endosonographic features had no association with outcome after GTN treatment.

Abstract
INTRODUCTION Anal fissures are commonly encountered in routine colorectal practice. Developments in the pharmacological understanding of the internal anal sphincter have resulted in more conservative approaches towards treatment. Simple measures are often effective for early fissures. Glyceryl trinitrate is well established as a first-line pharmacological therapy. The roles of diltiazem and botulinum, particularly as rescue therapy, are not well understood. Surgery has a defined role and should not be discounted completely. METHODS Data were obtained from Medline publications citing 'anal fissure'. Manual cross-referencing of salient articles was conducted. We have sought to highlight various controversies in the management of anal fissures. FINDINGS Acute fissures may heal spontaneously, although simple conservative measures are sufficient. Idiopathic chronic anal fissures need careful evaluation to decide what therapy is suitable. Pharmacological agents such as glyceryl trinitrate (GTN), diltiazem and botulinum toxin have been subjected to most scrutiny. Though practices in the UK vary, GTN or diltiazem would be suitable as first-line therapy with botulinum toxin used as rescue treatment. Sphincterotomy is indicated for unhealed fissures; fissurectomy has been revisited and advancement flaps have a role in patients in whom sphincter division is not suitable.

Abstract
INTRODUCTION In the last few years, the medical treatment of chronic anal fissure (chemical sphincterotomy) has been introduced as a consequence of the morbidity attributed to surgical sphincterotomy. However, medical treatment has two disadvantages: moderate effectiveness (between 30% and 80%) and the need for treatment to be prolonged for more than 8 weeks. OBJECTIVE To evaluate initial response to topical diltiazem 2% topical gel as a predictive factor in the curability of chronic anal fissure. PATIENTS AND METHOD From February 2004 to December 200, all patients with a history of anal fissure of more than 6 weeks were included in this study. Pregnant patients and those with prior anal surgery, inflammatory bowel disease, diltiazem intolerance and problems for maintaining contact during follow-up were excluded. A magistral formula of diltiazem 2% gel was used in three applications daily for 8 weeks. Patients were followed-up clinically and pain was measured through a visual analog scale (VAS) at the end of weeks 1, 3, 6, and 8. Groups with and without response to diliazem were compared through the chi2 test, Fisher's exact test and Student's t-test. A Receiver Operating Characteristic (ROC) curve was used to evaluate the diagnostic efficacy of initial pain response to diliazem, as well as sensitivity, specificity and predictive values. RESULTS One hundred patients (70 men), with a mean age of 43 years (22-76) were analyzed. Localization was posterior in 87%, anterior in 11% and lateral in 2%. All patients had pain, 65 had bleeding, and 13 had pruritus. At the end of the 8-week treatment, cure was achieved in 62%, with morbidity of 5% (mild headache in 2%, and pruritus in 3%). No significant differences were found between the groups with and without response to diltiazem 2% in terms of age, sex, localization, bleeding, or pruritus. Notable differences were found in the VAS for pain at the end of weeks 1, 3, 6, and 8 between the two groups (p = 0.00). ROC curves established a cut-off point of 4 in the VAS at the end of week 1, with an area below the curve of 0.925 (95% CI, 0.858-0.989). The capacity of early response to diliazem to predict curability showed a sensitivity of 85.5% (95% CI, 74.7%-92.2%), a specificity of 92.1% (95% CI, 79.2%-97.3%), a positive predictive value of 94.6% (95% CI, 85.4%-98.2%), and a negative predictive value of 79.5% (95% CI, 65.5%-88.8%). Among patients who showed no response to diltiazem by the end of week 1, cure was achieved in only 9% at 8 weeks. In contrast, among those with a favorable response in the first week, cure was achieved in 94.6%. CONCLUSIONS Lack of response to topical diltiazem 2% gel at the end of the first week reliably predicts failure of medical treatment for chronic anal fissure, obviating the need to prolong treatment for 8 weeks.

Abstract
Chronic anal fissure (CAF) is usually associated with internal anal sphincter spasm, the relief of which is central to provide fissure healing. The treatment for CAF has undergone a transformation in recent years from surgical to medical. Both the approaches share the common goal of reducing the spasm. Though surgical treatment has a high success rate, it can permanently impair fecal continence in a large number of patients. Smooth muscle relaxation seems to be a novel way by which more than 60% of the patients can be cured with the topical use of the agents. This treatment is in addition to the normalization of stools mostly. Smooth muscle relaxation is well tolerated, can be administered on an outpatient basis, does not cause any lesion of the continence organ, and subsequently, does not lead to any permanent latent or apparent fecal incontinence. This review encompasses various agents that are used for smooth muscle relaxation. In addition, it describes various clinical studies reported in the literature with their success rates and side effects.
