Hemorrhoids and anal fissures are two of the most common benign anorectal diseases. Despite their high prevalence, diagnostic accuracy of benign anorectal disease is suboptimal at 70% for surgeons, especially for hemorrhoidal diseases. Once the diagnosis is correctly made, numerous medical and surgical treatment options are available, each with different rates of success and complications. In this article, the authors review each step of patient management, with emphasis on evidence-based treatment options for hemorrhoids and anal fissures. The article discusses the pathophysiology, diagnosis, medical management, and procedures for hemorrhoids followed by a detailed overview on the management of anal fissures.

BACKGROUND: Medical treatment, including glyceryl trinitrate ointment, represents the first step for the management of chronic anal fissure. However, glyceryl trinitrate ointment is associated with headache and, consequently, a high withdrawal rate of the treatment. OBJECTIVE: The aim of the present study was to evaluate the effect of the topical application of tocopherol acetate ointment on pain relief and chronic anal fissure epithelialization, comparing it with the effect of a standard treatment with glyceryl trinitrate ointment. DESIGN: This is a 2-parallel-group, single-center, randomized controlled, intent-to-treat clinical trial. SETTINGS: This study was conducted at the Garcilaso Clinic affiliated with Universidad Alfonso X (Madrid, Spain). PATIENTS: Patients with chronic anal fissure were selected. INTERVENTIONS: Patients were randomly assigned into 2 groups: patients receiving tocopherol acetate ointment and patients receiving glyceryl trinitrate ointment. MAIN OUTCOME MEASURES: The primary end point was quantification of anal pain 8 weeks after beginning the treatment as measured by a Visual Analogue Scale ranging from 0 to 100 mm. The secondary end points were the healing rate (during the treatment period of 8 weeks) and the recurrence rate. RESULTS: One hundred sixty consecutive patients were treated, 80 in each group. By 8 weeks after treatment, mean anal pain score declined by 56.2 mm in the glyceryl trinitrate ointment group compared with a mean anal pain score decline of 67.1 mm in the tocopherol acetate ointment group (mean difference, 10.9 mm (95% CI, 4.3-18.6); p = 0.018). Sixteen weeks after finishing the therapy, the recurrence rate was 13.2% in the glyceryl trinitrate ointment group vs 2.9 in the tocopherol acetate ointment group (p = 0.031). LIMITATIONS: Limitations of the study include the absence of manometric measurements of the internal anal sphincter before and after the treatments and the use of glyceryl trinitrate ointment as an active comparator, whereas calcium channel blockers are actually the standard treatment. CONCLUSIONS: Anal pain was significantly lower in the tocopherol acetate ointment group than in the glyceryl trinitrate ointment group at 8 weeks after treatment. Tocopherol acetate ointment achieved a greater healing rate and a lower recurrence rate 16 weeks after finishing the treatment. See Video Abstract at http://links.lww.com/DCR/B751.

Sin embargo, la pomada de trinitrato de glicerilo se asocia con cefalea y, en consecuencia, una alta tasa de cancelación del tratamiento.OBJETIVO:El objetivo del presente estudio fue evaluar el efecto de la aplicación tópica de pomada de acetato de tocoferol en el alivio del dolor y la epitelización de la fisura anal crónica, comparándolo con el efecto de un tratamiento estándar con pomada de trinitrato de glicerilo.DISEÑO:Ensayo clínico con intención de tratar controlado, aleatorizado, de un solo centro, con dos grupos paralelos.ESCENARIO:Clínica Garcilaso adscrita a la Universidad Alfonso X (Madrid, España).PACIENTES:Pacientes con fisura anal crónica.INTERVENCIONES:Los pacientes fueron aleatorizados en 2 grupos: pacientes que recibieron pomada de acetato de tocoferol y pacientes que recibieron pomada de trinitrato de glicerilo.PRINCIPALES MEDIDAS DE RESULTADO:El criterio de valoración principal fue la cuantificación del dolor anal 8 semanas después de comenzar el tratamiento, medido por la escala analógica visual que varía de 0 a 100 mm. Los criterios de valoración secundarios fueron la tasa de curación (durante el período de tratamiento de 8 semanas) y la tasa de recurrencia.RESULTADOS:Se trataron ciento sesenta pacientes consecutivos, 80 en cada grupo. A las ocho semanas después del tratamiento, la puntuación media de dolor anal se redujo en 56.2 mm en el grupo de pomada de trinitrato de glicerilo en comparación con una disminución de la puntuación de dolor anal medio de 67.1 mm en el grupo de pomada de acetato de tocoferol (diferencia media: 10.9 mm (intervalo de confianza del 95%; 4.3 a 18.6; p = 0.018) Dieciséis semanas después de finalizar la terapia, la tasa de recurrencia fue del 13.2% en el grupo de pomada de trinitrato de glicerilo frente a 2.9 en el grupo de pomada de acetato de tocoferol (p = 0.031).LIMITACIONES:Ausencia de medidas manométricas del esfínter anal interno antes y después de los tratamientos. Ungüento de trinitrato de glicerilo como comparador activo, mientras que los bloqueadores de los canales de calcio son en realidad el tratamiento estándar de oro.CONCLUSIONES:El dolor anal fue significativamente menor en el grupo de ungüento de acetato de tocoferol que en el grupo de ungüento de trinitrato de glicerilo a las 8 semanas después del tratamiento. La pomada de acetato de tocoferol logró una mayor tasa de curación y una menor tasa de recurrencia 16 semanas después de finalizar el tratamiento.

BACKGROUND: Anal fissure is a common complication of the anorectal region and one of the most reported causes of anal pain. Acute anal fissure can be cured by surgery or medical treatment. There is an increase in the use of topical therapy for the treatment of anal fissures. A common topical drug used is Diltiazem (DTZ), a calcium-channel blocker, which relaxes the anal sphincter and thus promotes healing of the anal fissure. Moist exposed burn ointment (MEBO) is an ointment that is effective for the treatment of burns and wound healing and is becoming popular in the treatment of anal fissures. METHODS: This is a 1:1:1 randomized, controlled, parallel design, with endpoint measures of change in pain score, wound healing, defecation strain score and patient's global impression of improvement. The study will be conducted at AUBMC over a 10-week period. Patients will be randomized to three treatment arms: MEBO, Diltiazem, and a combination of MEBO and Diltiazem ointments. DISCUSSION: The results of this study will allow physicians to assess the efficacy and safety of MEBO in the treatment of acute anal fissure, and also in comparison to Diltiazem. This trial will generate evidence-based conclusions regarding the use of a herbal/natural-based product (MEBO ointment) for the treatment of anal fissures.

RESUMEN La fisura anal es una patología proctológica frecuente caracterizada por un desgarro oval en el anoder mo que, si bien es pequeño, puede producir mucho dolor y angustia en el paciente. La etiología exacta aún se discute, pero está relacionada con una hipertonía del esfínter anal en la mayoría de los casos. El tratamiento inicial es médico, con fármacos que disminuyen el tono del esfínter anal. Las fisuras cróni cas generalmente requieren tratamiento quirúrgico. La esfinterotomía interna lateral tiene un elevado porcentaje de éxito y se considera el tratamiento de referencia. En este artículo haremos una revisión de la anatomía, fisiopatología y opciones terapéuticas actuales de las fisuras anales.


ABSTRACT Anal fissure is a common anorectal condition. While it often presents as a small oval tear in the anoderm, it can cause significant pain and anguish to the patient. The exact etiology is still debatable but increased anal tone is associated with most fissures. The initial management is medical with agents intended to reduce the anal tone. More chronic fissures usually require surgical intervention. Lateral internal sphincterotomy has a high success rates and is considered the gold standard of interventions. In this article we review the relevant anatomy, pathophysiology and contemporary treatment options for anal fissures.

BACKGROUND/AIMS: An anal fissure (AF) is a linear tear in the distal anal canal and is one of the most common causes of anal pain. Hemorrhoidal disease (HD) is a symptomatic growth and distal displacement of normal anal cushions. Numerous studies have addressed the contributing factors of these conditions, yet the results remain controversial. In this study, we hypothesize that increasing patients' awareness of hidden risk factors could reduce the rate of HD and AF. MATERIALS AND METHODS: A questionnaire-based controlled study was planned. After power analysis, patients with HD (n=60) and AF (n=60) were enrolled consecutively into the study group and compared with the control group (n=60) of healthy individuals. The survey was designed to assess the participants' toilet and dietary habits and anxiety risk. Odds ratios were calculated and a binary logistic regression model was constructed to identify associated factors. RESULTS: Hard stools, spending more than 5 minutes in the toilet, frequent straining during defecation, and increased spice intake were more frequent in the patients with HD; and hard fecal consistency, time elapsed in toilet greater than 5 min, straining during defecation, and high anxiety risk were more frequent in the patients with AF as compared to the control group (p<0.05). CONCLUSION: Possible associations were identified between habitual factors or conditions (i.e., fecal consistency, the time elapsed in the toilet, straining during defecation) and anxiety and benign anorectal diseases (i.e., HD and AF). Patients should be advised about these hidden threats.

BACKGROUND: Anal fissure which is defined as a longitudinal tear in anoderm below the dentate line is one of the most common benign diseases of anorectal area. Severe pain during the defecation and emotional stress that it causes may reduce people's quality of life. AIMS: In this randomized clinical trial, we aimed to compare the efficiency of the topical ointment with medical treatment and surgical lateral internal sphincterotomy. METHOD: This is a randomized clinical trial of 550 patients who were treated for chronic anal fissure. Patients were randomly divided into 4 groups according to the treatment type they received. RESULTS: In a vast majority of the patients, the primary complaint was pain (92.3%) and bleeding during defecation (62%). Both pain relief and healing of the fissure, which are the components of response to treatment, had not been observed in 56 (37.3%) patients of topical nitroglycerin ointment group until the second month. Among the recalcitrant patients in both topical nitroglycerin (56) and topical diltiazem ointment (47) groups, 27 (48.2%), and 36 (76.5%) patients underwent surgery, respectively. The best response to treatment was also obtained in lateral internal sphincterotomy group. CONCLUSION: LIS is still the gold standard for the treatment of chronic anal fissure when the physicians would like to avoid recurrence and obtain the best pain relief.

PURPOSE OF REVIEW: Anal fissures are very common. They are easy to diagnose and treat in the office setting. They may coexist with hemorrhoids. In fact 20% of patients with hemorrhoids have anal fissures also. The purpose of this review is to highlight current diagnosis and treatment of anal fissures using diet, ointments and botulinum toxin to enable healing. Medical treatment relies on reducing anal sphincter spasm to allow improved blood flow and healing. RECENT FINDINGS: Many anorectal disorders can be managed in the office. Most anal fissures can be managed without the need for surgery. The need for anorectal examination, including use of anoscopy is stressed in the current literature. The use of calcium channel blockers in preference to nitroglycerin is highlighted as well as the use of botulinum toxin when ointments don't work. SUMMARY: Anal fissure can be managed nonsurgically most of the time and gastroenterologists should be able to manage them. This article should help in preventing unnecessary surgery and its complications, mainly incontinence in a small but significant number. The search for more effective drugs and options for managing this disorder continues.

AIM: Current questionnaires designed to evaluate the burden of haemorrhoidal disease ignore symptoms such as bleeding, pain and itching. A specific questionnaire is needed to evaluate the global impact of anal disorders on patients' daily lives. METHOD: We developed a questionnaire (HEMO-FISS-QoL) to assess the symptom burden of anal disorders and administered it to 256 patients (mean age 46.2 years; men 60.4%) with haemorrhoidal disease (67.2%), anal fissure (29.3%) or both (3.5%). Psychometric properties were evaluated by testing the acceptability, construct validity and reliability of the questionnaire. Principal components and multi-trait analyses were used to identify dimensions and to assess construct validity. Backward Cronbach alpha curves and a graded response model were used to reduce the number of items and modalities. External validity was evaluated against SF-12 and the Psychological Global Well-Being Index (PGWBI) using Spearman's correlation coefficient. RESULTS: Principal component analysis defined four dimensions: physical disorders, psychology, defaecation and sexuality. The number of questions was reduced from 38 to 23. The HEMO-FISS-QoL scores correlated well with those of the SF-12 and PGWBI (P < 0.001). Cronbach's coefficients (all > 0.7) reflected good internal reliability of the different dimensions. The total score increased with the severity of the anal disorders and with their consequences (days off work and personal spending related to the disease). CONCLUSION: The HEMO-FISS-QoL questionnaire reliably evaluates the global impact of haemorrhoids and anal fissures on patients' daily lives. This simple tool may prove useful for treatment evaluation in clinical trials and daily practice.

Anal fissure is a common ailment, however, the pathophysiology and optimal treatment strategy is unclear. Anal fissures may be classified as acute or chronic. Acute fissures are effectively treated and prevented with conservative measures, whereas chronic fissures typically require medical or surgical therapy. Invasive interventions have superior healing rates compared with local medical therapies, but may cause persistent incontinence. New interventions are constantly introduced and may be of value in patients with high risk of incontinence, but more evidence is currently needed.

This is a single institution nonexperimental study intended to analyze the therapeutic efficacy of topical diazepam in treating symptoms of chronic anal fissures.Anal fissures are a common cause of anal pain. Conventional treatments include nonsteroidal anti-inflammatory drugs, topical creams, such as nitroglycerin and nifedipine, and surgery. However, these treatments are usually suboptimally efficacious or have deterring side effects.Patients at an outpatient community center with a diagnosis of a chronic anal fissure were prescribed either topical 2% (n = 19) or 4% (n = 18) diazepam cream between January 2013 and February 2015. We retrospectively analyzed their responses to treatment.All 19 patients using 2% diazepam cream experienced a positive response in pain, whereas 47.4% experienced a complete response, with a numerical rating scale (NRS) score of 0 (0-10). Eighty-eight percent of patients using 4% dose had a positive response in pain, whereas 23.5% experienced a complete response. Ninety-four percent of patients using 2% dose had a positive response in anal bleeding, whereas 68.8% experienced a complete response with an anal bleeding score (ABS) of 2 (2-9). Ninety-four percent of patients using 4% dose had a positive response in anal bleeding, whereas 64.7% experienced a complete response. Only 1 patient reported a side effect from diazepam cream-perianal pruritus.Both 2% and 4% topical diazepam provided significant pain and bleeding relief from chronic anal fissures that were refractory to conventional therapies. There were insignificant differences when assessing independent comparisons for pain and bleeding between the doses.

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.

AIM: This study compared the efficacy of topical captopril with topical diltiazem in the treatment of chronic anal fissure (CAF). METHOD: Fifty patients aged between 15 and 75 years with CAF were included in a prospective randomized, double-blind clinical trial. They were randomly allocated to either captopril (0.5%) cream or diltiazem (2%) cream in a dose of 2 cm of cream on the perianal skin every 12 h for 8 weeks. The intensity of pain upon defaecation was evaluated every 10 days using a visual analogue scale. Bleeding on defaecation, pruritus and the presence of perianal irritation were also recorded before and during the trial. RESULTS: The average pain scores were lower in the diltiazem group on the 20th and 30th days. From day 40 to the end of the trial the average pain scores of the two groups did not differ significantly. There were no significant differences in bleeding or perianal irritation between the groups, but the incidence of pruritus was considerably higher in the captopril group, and at the end of the trial 45.8% of the patients in this group still suffered from pruritus. CONCLUSION: Topical captopril and diltiazem were found to be equally effective in the management of pain, bleeding and perianal irritation due to CAF, but due to the high incidence of pruritus observed with topical captopril this medication is not recommended for the treatment of CAF.

PURPOSE: The treatment of high transsphincteric fistula is a complex procedure, which may be associated with the risk of recurrence and fecal incontinence. In this study, we used an animal model to compare different types of sphincter-preserving treatments for transsphincteric fistula. METHODS: Sixteen female New Zealand rabbits, weighing 2.8-4.8 kg underwent a surgical creation of high transsphincteric fistula. After 6 weeks, magnetic resonance imaging (MRI) was performed in order to confirm fistula formation and measure the fistula diameter. The rabbits were divided into three groups. Group 1 received no plug treatment (control). Autologous dermal graft and acellular dermal matrix were used as a plug in groups 2 and 3, respectively. Five weeks after treatment, fistula tract healing was determined by measuring the largest fistula diameter with MRI. All rabbits were euthanized and the anorectum excised en bloc for histopathological examination. RESULTS: According to the MRI findings, all groups showed significant healing after the treatment (p < 0.05). The healing rate of fistula diameters after treatment was 40, 66, and 29% in the control, dermal graft, and acellular dermal matrix groups, respectively. In terms of negative healing parameters such as neutrophil, eosinophil, lymphocyte, and plasmocyte accumulation, dermal graft and acellular dermal matrix groups showed significantly lower results than those in the control group (p < 0.05). CONCLUSION: According to MRI and histopathological results, fistula tract curettage and fistula orifice closure improved transsphincteric anal fistula healing. Additionally, in this study, plug treatment favoring autologous dermal graft resulted in better healing.
