Abstract
OBJECTIVES The aim of the study was to evaluate the effect of botulinum toxin (BT) injection on fissure healing in the treatment of chronic anal fissure (CAF) in outpatient conditions without any analgesia and sedation to the internal anal sphincter (IAS). The primary outcome measure was post-procedural pain. The secondary outcome measures were fissure healing and complications. METHODS Prospectively preserved data of 67 patients who received BT injections for CAF were analyzed prospectively. Demographic data, duration of symptomatic improvement, fissure location and number, parity, post-procedural pain, complications, continence status, response to treatment, and duration of follow-up were examined. Participants received bilateral (50 + 50 units) BT injections into the internal anal sphincter (IAS) in an outpatient setting. RESULTS Symptomatic improvement was observed in 58% of patients within 1 week. The complete response rate to treatment was 82% at a mean follow-up of 6 months. Patients with partial response to treatment (10%) were successfully treated with topical therapy, and patients with persisting fissures (8%) were successfully treated with partial lateral internal sphincterotomy (LIS). 14 patients (21%) reported some degree of transient incontinence at follow-up. Multiparous women experienced more symptoms of Incontinence (p = 0.00). Pre- and post-procedural Vas Score median values were 4. The 7th-week VAS score median value was 3. CONCLUSION Dysport injection under sedation-free outpatient conditions is an effective and safe alternative to LIS for the treatment of CAF, with tolerable procedural pain. All patients should be warned of transient incontinence.

Abstract
Botulinum toxin (BTA) is a bacterial-derived extract that can inhibit muscle contraction, acting directly on the absorption of acetylcholine. Thanks to this property, botulinum has been used in aesthetic and general medicine for several years. Nowadays, the use of botulinum toxin is being deepened to address the problem of bruxism. In this scoping review, the results of the studies in the literature of the last 10 years were analyzed. Indeed, 12 reports (found on PubMed, Web of Science, and Scopus, entering the keywords "BRUXISM" and "BOTULINUM TOXIN") were deemed eligible for inclusion in this review. In the studies reviewed, BTA was injected into different muscle groups: masseters, masseter and temporalis or masseter, temporalis, and medial pterygoid. Botulinum toxin injection is a viable therapeutic solution, especially in patients with poor compliance or without improvement in conventional treatment.

Abstract
Introduction: Anal fissure is a longitudinal tear of the mucosa of the anal canal extending from the outer anal orifice in the direction of the dentate line of the inner anal opening. Fissures are divided into primary and secondary, and acute or chronic. Besides minimal rectal bleeding, itching and soiling, primary chronic anal fissures (PCAF) manifest with anal pain as theirs main determinant. It is described as the most troubling symptom. Aim: To compare the effect of injection therapy with botulinum toxin A (ITBT) vs. anal dilation (AD), and local nifedipine with lidocaine (LNL) in pain treatment of PCAF. Materials and Methods: This controlled retrospective prospective longitudinal study covered 94 patients, divided in 3 groups. The first was treated with ITBT, the second with AD and third using LNL (31, 33 and 30 patients respectively). Clostridium botulinum toxin A was used, dissolved with saline to concentration of 200 U/ml. The solution was applied to both sides of PCAF at dose of 40U. Modified technique of AD was done using 3 fingers of a single hand, progressively introduced into the anal canal, followed by gradual lateral distraction during 1 min. LNL therapy was conducted using nifedipine (0.3%) with lidocaine (1.5%) ointment, applied twice daily for 3 weeks. To measure pain, a visual analog scale (VAS) was used. The follow-up period was 12 weeks with checkup at week 4. Results: The median age of participants was 46.6±13.9 years (50 males vs. 44 females). The type of therapy had a significantly different effect on pain at week 4 (p=0.0003). Severe pain was present in only 2 ITBT patients, 16 AD, and 6 LNL patients. Post hoc analyses showed different pain disappearance time by week 12 (p <0.0001). The mean time was shortest in ITBT group (6.1±1.5 weeks). Anal pain intensity significantly differed among the 3 groups (Fisher exact, p=0.002). Namely, 71% in ITBT group rated the pain as weakest (VAS score 1) compared to 18.2% in AD and 30% of patients in LNL group. The overall pain reduction significance was in favor of ITBT, due to the differences between the ITBT and AD groups (p=0.00024) and ITBT compared to LNL group (p=0.018). Conclusion: ITBT is superior to AD and LNL in reducing pain in PCAF.

Abstract
BACKGROUND Topical treatments and botulinum toxin injections are valid options for the management of patients with chronic anal fissures (CAF), but little is known about the efficacy of these techniques in long-term follow-up. The aim of this meta-analysis was to evaluate the effectiveness, given to clinical outcomes, of medical treatments with calcium antagonists, nitroglycerin, and botulinum toxin on CAF treatment in adults. METHOD A systemic review and meta-analysis developed according to PRISMA [PLoS Med. 2009 Jul 21;6(7):e1000100; BMJ. 2010 Mar 23;340:c332] and registered in PROSPERO (Registration number: CRD42020120386). A systematic literature search was conducted through MEDLINE, EMBASE, Web of Science, and Cochrane Library databases. Randomized control trials that compared medical treatment were identified; publications had to have a clinical definition of CAF with at least one of the following signs or symptoms: visible sphincter fibers at the base of the fissure, anal papillae, sentinel piles, and indurated margins. The symptoms had to be chronic for at least 4 weeks. Data were independently extracted for each study, and a meta-analysis was drawn using fixed- and random-effects models. RESULTS 17 randomized trials met the inclusion criteria. Diltiazem showed a superior effect compared with glycerin (RR = 1.16 [95% CI = 1.05-1.30]; I2 = 18%) and with fewer adverse effects (RR = 0.13 [95% CI = 0.04-0.042]; I2 = 87%). Similar results were evidenced with the use of nifedipine compared with lidocaine (RR = 4.53 [95% CI = 2.99-6.86]; I2 = 28%). Botulinum toxin did not show statistically significant differences compared to glycerin (RR = 0.81 [95% CI = 0.02-29.36]; I2 = 93%) or isosorbide dinitrate (RR = 1.45 [95% CI = 0.32-6.54]; I2 = 85%). Regarding recurrence, nifedipine was superior to lidocaine (RR = 0.18 [95% CI = 0.08-0.44]; I2 = 31%). CONCLUSIONS Calcium channel blockers performed well regarding the healing of CAF when compared to others in long-term follow-up. The superiority of botulinum toxin was not evidenced compared to topical treatments. More studies are needed to better assess recurrence rates.

Abstract
BACKGROUND Anal fissure is a linear tear in the distal anoderm most frequently occurring in the posterior midline. Lateral internal sphincterotomy is considered the gold standard for the treatment of this condition. To this date, several pharmacological and neuromodulatory therapies have been tried out as alternative non-invasive treatments for anal fissures, however, the efficacy of some of these methods remains to be understood. OBJECTIVE the primary aim of this study was to review available literature on neuromodulatory treatments for recurrent anal fissure as a potentially effective cure for this condition. DATA SOURCES A search was conducted among five main online databases Embase, PubMed, Web of Science, Scopus, and Scholar. STUDY SELECTION All published human studies in English literature addressing neuromodulation for the treatment of recurrent anal fissure were selected. INTERVENTION neuromodulation for the treatment of anal fissure. We chose to include all articles in which the authors stated that the procedure they performed was via neuromodulation technique, or that the described technique used in their study resembled the technique. RESULT Among a total of 3487 evaluated studies, seven represented the effects of neuro modulation on treatment of recurrent anal fissure, among which two were randomized controlled trials and the rest were prospective studies. A total of 186 patient were evaluated in these studies. The mean age of the participants was 46.97 ± 8.2. The average VAS score before intervention was 7.77 ± 2.13, which decreased to 0.31 ± 1.13 after intervention. LIMITATIONS limitations of this study include the lack of related articles, and data regarding this subject. CONCLUSION Posterior tibial nerve stimulation (PTNS) provides rapid pain relief and fissure healing especially in short-to mid-terms with little to no complications, however, using this treatment, symptoms of anal fissure do not improve as well as LIS, especially in the long-term.

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
Benign anorectal disorders of structure and function are common in clinical practice. These guidelines summarize the preferred approach to the evaluation and management of defecation disorders, proctalgia syndromes, hemorrhoids, anal fissures, and fecal incontinence in adults and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was assessed using the Grading of Recommendations Assessment, Development and Evaluation process. When the evidence was not appropriate for Grading of Recommendations Assessment, Development and Evaluation, we used expert consensus to develop key concept statements. These guidelines should be considered as preferred but are not the only approaches to these conditions.

Abstract
BACKGROUND Lateral internal sphincterotomy (LIS) remains the gold standard surgical approach for the management of chronic anal fissures (CAF). The procedure however, is complicated by the risk of postoperative incontinence. Intrasphincteric Botulinum Toxin (BT) has gained popularity as an alternative approach, despite being inferior to LIS with regards to cure rates. In the real world, patients at high risk for postoperative incontinence are likely to be offered BT as a preliminary procedure. The aim of this study was to explore the real-world outcomes of LIS and BT for a cohort of CAF patients. METHODS 251 consecutive patients treated with either BT or LS for CAF by a single surgeon were reviewed. Patients were offered BT as a preliminary procedure if they had risk factors for faecal incontinence, whereas all other patients underwent LIS. Primary outcomes included rates of recurrence and faecal incontinence. RESULTS LIS was superior to BT with regards to recurrence rates throughout the mean follow up period of five years (5% vs 15%, p = 0.012). A total of 17 patients experienced a minor degree of flatal incontinence at the 6-week follow up, although there was no difference between LIS and BT (7% vs 6%, p = 1.000). Four LIS patients (2%) continued to experience some minor incontinence to flatus at the 12-month follow up and were managed with biofeedback. CONCLUSION For patients with CAF, individualizing the treatment approach according to risk factors for incontinence could mitigate this risk in LIS. High risk patients should be offered BT as a preliminary procedure.

Abstract
OBJECTIVE The overarching objective of the scoping review was to examine peer reviewed and grey literature for best practices that have been developed, implemented and/or evaluated for delayed discharge involving a hospital setting. Two specific objectives were to review what the delayed discharge initiatives entailed and identify gaps in the literature in order to inform future work. DESIGN Scoping review. METHODS Electronic databases and websites of government and healthcare organisations were searched for eligible articles. Articles were required to include an initiative that focused on delayed discharge, involve a hospital setting and be published between 1 January 2004 and 16 August 2019. Data were extracted using Microsoft Excel. Following extraction, a policy framework by Doern and Phidd was adapted to organise the included initiatives into categories: (1) information sharing; (2) tools and guidelines; (3) practice changes; (4) infrastructure and finance and (5) other. RESULTS Sixty-six articles were included in this review. The majority of initiatives were categorised as practice change (n=36), followed by information sharing (n=19) and tools and guidelines (n=19). Numerous initiatives incorporated multiple categories. The majority of initiatives were implemented by multidisciplinary teams and resulted in improved outcomes such as reduced length of stay and discharge delays. However, the experiences of patients and families were rarely reported. Included initiatives also lacked important contextual information, which is essential for replicating best practices and scaling up. CONCLUSIONS This scoping review identified a number of initiatives that have been implemented to target delayed discharges. While the majority of initiatives resulted in positive outcomes, delayed discharges remain an international problem. There are significant gaps and limitations in evidence and thus, future work is warranted to develop solutions that have a sustainable impact.

Abstract
Background: Botulinum toxin is an injectable neuromodulator that inhibits transmission between peripheral nerve endings and muscle fibers, resulting in muscle paralysis. Botulinum toxin type A is the most common form of botulinum toxin used in clinical practice. Methods: In this review, we examine the mechanism of action, formulations, common clinical use in the genital-urinary tract, and potential clinical use in pelvic floor disorders of botulinum toxin type A. Results: Several aspects of botulinum toxin A make it a favorable therapeutic tool, including its accessibility, its longevity, and its impermanence and reversibility of resultant chemodenervation in a relatively short and safe manner. Although botulinum toxin A has well-established efficacy in treating refractory overactive bladder and neurogenic detrusor overactivity, its use in pelvic floor disorders is still in its infancy. Conclusion: The efficacy of botulinum toxin A for treating pelvic pain, voiding dysfunction, muscle pain and dysfunction, and certain colorectal-related pain issues shows promise but requires additional rigorous evaluation.

Abstract
Objectives: Hemorrhoid is a common disease in surgical practice, but only a few numbers of patients need surgical treatment. The most common concern of patients is postoperative pain. This study aimed to evaluate the efficacy and safety of an intersphincteric injection of botulinum toxin for post-hemorrhoidectomy pain relief. Methods: Overall, 90 patients were enrolled, and 44 were randomized into a botulinum toxin injection group. Preoperative gradings were grade III 37 patients and grade II 2 patients. Patients received an intersphincteric injection of 0.5 ml of a solution containing 30 units of botulinum toxin (BTX). The postoperative data were collected pain score in a visual analog score (VAS), an analgesic used, hospital stay, and complication. Results: The VAS was lower in the BTX group at 12 hours and 24 hours postoperative phase. VAS at 12 hours 4.435 ± 2.149 vs 6.232 ± 2.307 (p < 0.001), VAS at 24 hours 2.205 ± 2.079 vs 3.744 ± 2.361(p = 0.003). The BTX group has a shorter time in defection without pain than the control group (3 vs. two days, p = 0.007). There was no difference in immediate and delay complications between the two groups. Conclusions: Postoperative hemorrhoidectomy needs multimodalities for pain reduction. Botulinum toxin has some benefit in postoperative pain reduction.

Abstract
Background: One of the most frequent distressing diseases which causes anal pain and bleeding after defecation is anal fissure. Despite a poorly understood pathogenesis, the internal anal sphincter spasm has been identified to play a central role in pathogenesis. Recently, botulinum toxin is being used increasingly for the treatment of chronic anal fissure to achieve chemical sphincterotomy and reduce internal sphincter tonicity. Based on the heterogeneity among the published studies, we aimed this study to evaluate its healing rate and for recognizing the factors of patients which may affect the outcome. Subjects and Methods: In a prospective case series medical research, 106 patients who suffer from chronic anal fissure were treated by botulinum toxin injections. All patients received 30 units of botulinum toxin and were physically examined every week for 2 months. They were evaluated for bleeding, pain, hematoma, thrombosis, infection, incontinence, and healing of the fissure. At the end of the follow-up period, the fissure healing rate and its relation to age, gender, prior topical therapy, duration of symptoms, and the position of the fissure were assessed. Results: At the end of the study (8 weeks), the healing rate was 84.9% (90 patients responded to injections). Healing rate was higher in females and in patients who experienced a shorter duration of symptoms before injection. The mean healing time was 4.68 weeks. In addition, patients with one fissure (anterior or posterior) demonstrated higher healing rate and shorter healing time compared to patients with two fissures (anterior and posterior). Conclusion: This study demonstrated that botulinum toxin injection is safe and effective for the treatment of chronic anal fissures, with a low complication rate. In addition, the healing rate was higher in females, patients with shorter duration of symptoms, and those with one fissure.

Abstract
AIM Chronic anal fissures (CAFs) are frequently encountered in coloproctology clinics. Chemical sphincterotomy with pharmacological agents is recommended as first-line therapy. Topical nitrates (TN) heal CAF effectively but recurrences are common. An alternative treatment modality is injection of botulinum toxin (BT) into the anal sphincter. We aimed to perform an updated systematic review and meta-analysis to compare the effectiveness of BT and TN in the management of CAF. METHOD PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until March 2017. All randomized controlled trials (RCTs) that reported direct comparisons of BT and TN were included. Two independent reviewers performed methodological assessment and data extraction. Random effects models were used to calculate pooled effect size estimates. RESULTS Six RCTs describing 393 patients (194 BT, 199 TN) were included. There was significant heterogeneity among the trials. On random effects analysis there were no significant differences in incomplete fissure healing (OR = 0.47, 95% CI 0.13-1.68, P = 0.24) or recurrence (OR = 0.70, 95% CI 0.39-1.25, P = 0.22) between BT and TN, respectively. BT was associated with a higher rate of transient anal incontinence (OR = 2.53, 95% CI 0.98-6.57, P = 0.06) but significantly fewer total side effects (OR = 0.12, 95% CI 0.02-0.63, P = 0.01) and headache (OR = 0.10, 95% CI 0.02-0.60, P = 0.01) compared with TN. CONCLUSION BT is associated with fewer side effects than TN but there is no difference in fissure healing or recurrence. Patients need to be warned regarding the risk of transient anal incontinence associated with BT.

Abstract
BACKGROUND Anal fissure is the most common anal disease in children. In the past few decades, the understanding of its pathophysiology has led to a progressive reduction in invasive procedures in favor of conservative treatment based on stool softeners and the relaxation of the anal sphincter. This randomized controlled study assessed the safety and efficacy of nitroglycerine (NTG) ointment in the treatment of pediatric anal fissure, which had not yet been proved. PATIENTS AND METHODS An unequal randomized controlled study included 105 pediatric patients with anal fissure who had presented to the private and outpatient clinics of the Central Teaching Hospital of Pediatrics during the period from February 2015 to May 2016. The control group consisted of 70 patients. Both groups were treated with classical conservative therapy of sitz bath, stool softener, and local anesthetic. In the second group, chemical sphincterotomy with 0.2% NTG ointment was used in 35 patients, and was applied at the anal canal twice daily for 8weeks. The primary outcomes of symptomatic improvement and healed fissure, as well as side effects, were analyzed. RESULTS The average age of patients was 2years (range, 4months to 5years). Patients in the NTG group had 77% symptomatic relief and 60% healed fissure compared to the control group, which had 54% and 32.8% respectively. All were statistically significant. No serious adverse effects were noticed during the treatment period. CONCLUSION The use of 0.2% NTG ointment is an effective therapy for anal fissure in children in terms of good healing rate and rapid symptom relief, but it has the drawback of a long treatment period, making patient compliance more difficult, in addition to the problems of tolerance and recurrence. TYPE OF STUDY Prospective randomized controlled study (treatment study). LEVEL OF EVIDENCE Type 2.

Abstract
Highlights Chronic anal fissure is a common condition associated with intense pain.Local botulinum toxin injection is a valid option in its management.Pain intensity scores significantly improved after BoNT injection.Side effects were rare and mild.Our results support the inclusion of BoNT in the management algorithm of chronic anal fissure. Introduction Chronic anal fissure is a common condition associated with intense pain. Local botulinum toxin injection is a valid option in its management. The purpose of this study was to evaluate the efficacy of botulinum toxin on pain relief in chronic anal fissure patients. Methods We conducted a retrospective cohort study, involving 81 consecutive patients referred to a chronic pain management unit due to a chronic anal fissure for treatment with botulinum toxin, during a 4 year period. Data were collected from hospital records regarding pre-treatment and post-treatment pain (numeric rating scale), side effects, need for botulinum toxin reinjection and need for surgical treatment. We used standard statistical methods for inter (t-test and qui2) and intra-group (paired sample t-test) comparisons, according to variables distribution. Results Pain intensity rest score significantly improved after BoNT injection [variation: -4.2 ± 2.9 (p < 0.001)], as did pain post-defecation score [variation: -5.1 ± 3.0 (p < 0.001)]. 8.6% needed botulinum toxin reinjection and 23.5% were submitted to surgery. Side effects were reported in 8.6%. Discussion The efficacy of botulinum toxin use on pain reduction along with its non-permanent and minor side effects support its role in the resolution of chronic anal fissure. However, treatment failure in the long term is still significant. Conclusion Botulinum toxin is effective on pain relief in patients with chronic anal fissure, which supports its inclusion in the management algorithm of this condition.

Abstract
BACKGROUND Anal fissure has a very large number of treatment options. The choice is difficult. In an effort to assist in that, choice presented here is a systematic review and meta-analysis of all published treatments for anal fissure that have been studied in randomized controlled trials. METHODS Randomized trials were sought in the Cochrane Controlled Trials Register, Medline, EMBASE and the trials registry sites clinicaltrials.gov and who/int/ictrp/search/en. Abstracts were screened, full-text studies chosen, and finally eligible studies selected and abstracted. The review was then divided into those studies that compared two or more surgical procedures and those that had at least one arm that was non-surgical. Studies were further categorized by the specific interventions and comparisons. The outcome assessed was treatment failure. Negative effects of treatment assessed were headache and anal incontinence. Risk of bias was assessed for each study, and the strength of the evidence of each comparison was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS One hundred and forty-eight eligible trials were found and assessed, 31 in the surgical group and 117 in the non-surgical group. There were 14 different operations described in the surgical group and 29 different non-surgical treatments in the non-surgical group along with partial lateral internal sphincterotomy (LIS). There were 61 different comparisons. Of these, 47 were reported in 2 or fewer studies, usually with quite small patient samples. The largest single comparison was glyceryl trinitrate (GTN) versus control with 19 studies. GTN was more effective than control in sustained cure (OR 0.68; 95% CI 0.63-0.77), but the quality of evidence was very poor because of severe heterogeneity, and risk of bias due to inadequate clinical follow-up. The only comparison to have a GRADE quality of evidence of high was a subgroup analysis of LIS versus any medical therapy (OR 0.12; CI 0.07-0.21). Most of the other studies were downgraded in GRADE due to imprecision. CONCLUSIONS LIS is superior to non-surgical therapies in achieving sustained cure of fissure. Calcium channel blockers were more effective than GTN and with less risk of headache, but with only a low quality of evidence. Anal incontinence, once thought to be a frequent risk with LIS, was found in various subgroups in this review to have a risk between 3.4 and 4.4%. Among the surgical studies, manual anal stretch performed worse than LIS in the treatment of chronic anal fissure in adults. For those patients requiring surgery for anal fissure, open LIS and closed LIS appear to be equally efficacious, with a moderate GRADE quality of evidence. All other GRADE evaluations of procedures were low to very low due mostly to imprecision.

Abstract
BACKGROUND Chronic anal fissures are associated with significant morbidity and reduced quality of life. Studies have investigated the efficacy of botulinum toxin with variable results; thus, there is currently no consensus on botulinum toxin dose or injection sites. OBJECTIVE This study aimed to systematically analyze trials studying the efficacy of botulinum toxin for treatment of chronic anal fissure to identify an optimum dosage and injection regimen. DATA SOURCES A comprehensive review of the literature was conducted according to PRISMA guidelines. PubMed/Medline, Embase, Scopus, and the Cochrane Library were searched from inception to June 2015. STUDY SELECTION All clinical trials that investigated the efficacy of botulinum toxin for chronic anal fissure were selected according to specific criteria. INTERVENSIONS The interventions used were various doses of botulinum toxin. OUTCOME MEASURES Clinical outcomes, dosage, and injection site data were evaluated with weighted pooled results for each dosage and 95% confidence intervals. RESULTS There were 1158 patients, with 661 in botulinum toxin treatment arms, from 18 clinical trials included in this review. The outcomes of interest were 3-month healing, incontinence, and recurrence rates. Meta-regression analysis demonstrated a small decrease in healing rate (0.34%; 95% CI, 0-0.68; p = 0.048) with each increase in dosage, a small increase in incontinence rate (1.02 times; 95% CI, 1.0002-1.049; p = 0.048) with each increase in dosage and a small increase in recurrence rate (1.037 times; 95% CI, 1.018-1.057; p = 0.0002) with each increase in dosage. The optimum injection site could not be determined. LIMITATIONS This study was limited by weaknesses in the underlying evidence, such as variable quality, short follow-up, and a limited range of doses represented. CONCLUSIONS Fissure healing with lower doses of botulinum toxin is as effective as with high doses. Lower doses also reduce the risk of incontinence and recurrence in the long term.

Abstract
Chronic anal fissure is a painful disorder caused by linear ulcers in the distal anal mucosa. Even though it counts as one of the most common benign anorectal disorders, its precise etiology and pathophysiology remains unclear. Current thinking is that anal fissures are caused by anal trauma and pain, which leads to internal anal sphincter hypertonia. Increased anal basal pressure leads to diminished anodermal blood flow and local ischemia, which delays healing and leads to chronic anal fissure. The current treatment of choice for chronic anal fissure is either lateral internal sphincterotomy or botulinum toxin injections. In contrast to current thinking, we hypothesize that the external, rather than the internal, anal sphincter is responsible for increased anal basal pressure in patients suffering from chronic anal fissure. We think that damage to the anal mucosa leads to hypersensitivity of the contact receptors of the anal-external sphincter continence reflex, resulting in overreaction of the reflex. Overreaction causes spasm of the external anal sphincter. This in turn leads to increased anal basal pressure, diminished anodermal blood flow, and ischemia. Ischemia, finally, prevents the anal fissure from healing. Our hypothesis is supported by two findings. The first concerned a chronic anal fissure patient with increased anal basal pressure (170mmHg) who had undergone lateral sphincterotomy. Directly after the operation, while the submucosal anesthetic was still active, basal anal pressure decreased to 80mmHg. Seven hours after the operation, when the anesthetic had completely worn off, basal anal pressure increased again to 125mmHg, even though the internal anal sphincter could no longer be responsible for the increase. Second, in contrast to previous studies, recent studies demonstrated that botulinum toxin influences external anal sphincter activity and, because it is a striated muscle relaxant, it seems reasonable to presume that it affects the striated external anal sphincter, rather than the smooth internal anal sphincter. If our hypothesis is proved correct, the treatment option of lateral internal sphincterotomy should be abandoned in patients suffering from chronic anal fissures, since it fails to eliminate the cause of high anal basal pressure. Additionally, lateral internal sphincterotomy may cause damage to the anal-external sphincter continence reflex, resulting in fecal incontinence. Instead, higher doses of botulinum toxin should be administered to those patients suffering from chronic anal fissure who appeared unresponsive to lower doses.

Abstract
BACKGROUND Chronic anal fissure is a frequent and disabling disease, often affecting young adults. Botulinum toxin and lateral internal sphincterotomy are the main therapeutic options for refractory cases. Botulinum toxin is minimally invasive and safer compared with surgery, which carries a difficult post-operative recovery and fecal incontinence risk. The long-term efficacy of Botulinum toxin is not well known. OBJECTIVE The aim of this study was to evaluate the long-term efficacy and safety of Botulinum toxin in the treatment of chronic anal fissure. METHODS This was a retrospective study at a single center, including patients treated with Botulinum toxin from 2005 to 2010, followed over at least a period of 5 years. All patients were treated with injection of 25U of Botulinum toxin in the intersphincteric groove. The response was registered as complete, partial, refractory and relapse. RESULTS Botulinum toxin was administered to 126 patients, 69.8% (n = 88) were followed over a period of 5 years. After 3 months, 46.6% (n = 41) had complete response, 23.9% (n = 21) had partial response and 29.5% (n = 26) were refractory. Relapse was observed in 1.2% (n = 1) at 6 months, 11.4% (n = 10) at 1 year, 2.3% (n = 2) at 3 years; no relapse at 5 years. The overall success rate was 64.8% at 5 years of follow-up. Botulinum toxin was well tolerated by all patients and there were no complications. CONCLUSION The use of Botulinum toxin to treat patients with chronic anal fissure was safe and effective in long-term follow-up.

Abstract
Fissure in ano is a very common disorder of the anorectal region. Internal sphincter hypertonia with decreased relaxation coupled with mucosal ischemia of posterior anal canal are the major pathologies in chronic anal fissure (CAF). Though lateral internal sphincterotomy (LIS) remains the gold standard of treatment for the disease, it is accompanied by the potential complication of incontinence to both flatus and faecal matter. The aim of our study was to explore the role of topical diltiazem as an effective and a safe alternative to sphincterotomy for chronic anal fissure. Ninety patients with CAF were randomly assigned to group A and group B, with 45 patients each. Group A patients received 2 % diltiazem topical application, twice daily, and group B patients underwent LIS. All the patients were reviewed at first, fourth and sixth week after initiation of treatment. Visual analogue scores for pain and healing of fissure by visual inspection were recorded and compared. In group A, 71 % had complete healing of fissure at 6 weeks, with fair amount of pain relief (mean VAS-3.38), and in group B, 96 % showed healing of fissure, with excellent pain relief (mean VAS-1.87). Headache and flushing were noted in two patients in group A while no patients in group B developed incontinence. We conclude that LIS is more effective than topical diltiazem in the treatment of CAF. Topical diltiazem may be employed as an initial conservative treatment option before considering the surgical alternative.

Abstract
BACKGROUND There is paucity of data on the long-term outcome of the combination of fissurectomy and botulinum toxin A injection for the management of chronic anal fissure. OBJECTIVES The aim of this study is to assess the safety, efficacy, and long-term outcome of the combination of fissurectomy and botulinum toxin A injection. DESIGN This is a nonrandomized prospective cohort study. SETTINGS This study was conducted at a district general hospital in the United Kingdom. PATIENTS The cohort included all patients treated with fissurectomy and botulinum toxin A for chronic anal fissure between September 2008 and March 2012. INTERVENTION The patients were treated with a combination of fissurectomy and botulinum toxin A injection. MAIN OUTCOME MEASURES Symptomatic relief, fissure healing, complications, recurrence, and the need for further surgical intervention. RESULTS One hundred and two patients received fissurectomy and botulinum toxin A injection for chronic anal fissure. At 12-week follow-up, 68 patients had resolution of symptoms and complete healing of chronic anal fissure, 29 patients had improvement of symptoms but incomplete healing and had further topical or botulinum toxin A treatment with subsequent complete healing. Ninety-five patients (93%) reported no postoperative complications. Seven patients reported a degree of incontinence in the immediate postoperative period. All reported normal continence at12-week follow-up. No local complications were observed or reported. At the mean follow-up of 33 months, there was no evidence of recurrence. Twelve-month follow-up was conducted via telephone interview only. LIMITATIONS This study is nonrandomized and did not examine the dose response of Botulinum Toxin A. CONCLUSIONS Fissurectomy combined with high-dose botulinum toxin A is a safe, effective, and durable option for the management of chronic anal fissure and a promising alternative to surgical sphincterotomy.

Abstract
BACKGROUND Botulinum toxin (Botox) injection for chronic anal fissure (CAF) is commonly performed, yet there remains no consensus on optimal dosage or frequency of injections required to achieve complete resolution of anal fissure. The aim of this study was to determine the effectiveness of Botox and side-effect profile in the management of CAF. METHODS A retrospective clinical study of patients between 2010 and 2014 who underwent a Botox injection for CAF at a tertiary centre was performed. The effectiveness of Botox was measured using standardized outcomes including overall healing rate, presence of anal pain, recurrence and need for repeat botulinum injection. Binary outcomes were assessed using logistic regression model. The analysis was performed using Stata version 13 (StataCorp, College Station, TX, USA). RESULTS One hundred and one patients underwent 126 Botox injections within the study period. The mean first post-operative visit was at 1 month. The overall recurrence rate was 32%. The majority of patients were given 33 U. No statistically significant relationship between dose and recurrence was identified. The presence of pain at the first post-operative visit was a predictor of future recurrence (odds ratio 3.92, confidence interval 1.58-9.74, P = 0.003). CONCLUSION Botox is an effective strategy for CAF. Low doses can be given with good efficacy as highlighted by our audit and has the potential for great cost saving. The best predictor of recurrence is the presence of pain at the first post-procedure visit.

Abstract
BACKGROUND Botulinum toxin injection into the internal anal sphincter is gaining popularity as a second line therapy for chronic anal fissures if medical therapy fails. The dosage of botulinum toxin reported ranged from 20 to 50 IU with no more than 3 injection sites and results in a healing rate of 41%-88% at 3 months. We propose a new injection method of high-dose circumferential chemodenervation of 100 IU in treating chronic anal fissure. METHODS This was a retrospective review at a single academic center. 75 patients (50 women and 25 men) with uncomplicated chronic anal fissures underwent high-dose circumferential chemodenervation-internal anal sphincter (100 IU). We measured fissure healing, complication, and recurrence rates at 3 and 6 months post injection. RESULTS Of the 75 patients, healing rate was 90.7% at 3 months follow up with the first injection and 81.3% with the second injection. The recurrence rates were 20.6% and 12.5% at 6 months after the 1st and 2nd injections respectively. Excluding 5 patients who lost follow up, the total healing rate of the study cohort was 100%. At 2 weeks and 3 months, there were no major complications including hematoma, infection, flatus, fecal, and urinary incontinence. CONCLUSIONS High-dose circumferential chemodenervation-internal anal sphincter (100 IU) is a safe and effective method for uncomplicated chronic anal fissure.

Isosorbide dinitrate ointment vs botulinum toxin A (Dysport) as the primary treatment for chronic anal fissure: a randomized multicentre study. Colorectal Dis 2014; 16:O360-6.

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
These guidelines summarize the definitions, diagnostic criteria, differential diagnoses, and treatments of a group of benign disorders of anorectal function and/or structure. Disorders of function include defecation disorders, fecal incontinence, and proctalgia syndromes, whereas disorders of structure include anal fissure and hemorrhoids. Each section reviews the definitions, epidemiology and/or pathophysiology, diagnostic assessment, and treatment recommendations of each entity. These recommendations reflect a comprehensive search of all relevant topics of pertinent English language articles in PubMed, Ovid Medline, and the National Library of Medicine from 1966 to 2013 using appropriate terms for each subject. Recommendations for anal fissure and hemorrhoids lean heavily on adaptation from the American Society of Colon and Rectal Surgeons Practice Parameters from the most recent published guidelines in 2010 and 2011 and supplemented with subsequent publications through 2013. We used systematic reviews and meta-analyses when available, and this was supplemented by review of published clinical trials.

Abstract
BACKGROUND Although surgery is the gold standard treatment for anal fissure, the main concern remains its side effects and complications. Botulinum toxin injection and lateral internal sphincterotomy are technical options for patients suffering from chronic anal fissure. However, little is known about the efficacy of these two techniques. The aim of this meta-analysis was to compare the outcomes of botulinum toxin injection versus lateral internal sphincterotomy for chronic anal fissure. METHODS Original studies in English were searched from the MEDLINE database, PubMed, Web of Science, and the Cochrane Library database. Randomized control trials that compared botulinum toxin injection with lateral internal sphincterotomy were identified. Data were independently extracted for each study, and a meta-analysis was performed using fixed and random effects models. RESULTS Four hundred and eighty-nine patients from seven trials met the inclusion criteria. Patients undergoing lateral internal sphincterotomy had a higher-healing and incontinence rate. No statistically significant differences were noted in total complications between botulinum toxin injection and lateral internal sphincterotomy. Patients treated with lateral internal sphincterotomy had a significantly lower recurrence rate than the patients treated with botulinum toxin injection. CONCLUSIONS Our meta-analysis shows that lateral internal sphincterotomy was superior to botulinum toxin injection in terms of healing rate and lower recurrence rate. Botox, however, is safe associated with a lower rate of incontinence and could be used in certain situations. Further studies with a long-term follow-up are required to confirm our observations.

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
Pain after hemorrhoid surgery is the most common postoperative complication, significantly influencing patients' quality of life. Severe postoperative pain may still occur and continues to be the major concern of patients who are unwilling to undergo the surgery. Anal sphincter hypertonicity has been identified as a major influencing factor for increased pain after surgery. Since persistent internal anal sphincter spasm is a major factor responsible for the genesis of pain, relieving internal anal sphincter spasm is considered to be an effective method to ease the pain. Currently, multiple treatments have been used to manage pain after haemorrhoidal surgery, including sphincterotomy, botulinum toxin, glyceryl trinitrate, and calcium channel blockers. Haemorrhoidectomy coupled with spasmolysis therapy can significantly reduce the incidence of postoperative complications and improve the quality of life.
