Chinese expert consensus on clinical diagnosis and treatment of anal fissure (2021 edition) / 中华胃肠外科杂志

Anal fissure is a common anorectal disease, with anal pain as the main manifestation. Severe anal pain can affect the quality of life of patients. In clinical practice, there are some controversies about the treatment of anal fissure, especially the surgical indications. Improper surgical procedures will even cause anal incontinence. However, consensus opinions on anal fissure have not yet been formulated in China. On the basis of summarizing research progress in this field at home and abroad, combined with expert experience, and according to the principle of evidence-based medicine, the Clinical Guidelines Committee has organized experts in this field to form an expert consensus with 13 recommendations on diagnosis, evaluation and treatment of anal fissure for clinicians' reference.

Fisura anal: anatomía, patogenia y tratamiento / Anal fissure - anatomy, pathogenesis and treatment

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.

Evaluation of outcomes in fissurectomy and V-Y advancement flap for the treatment of chronic anal fissure / Avaliação de desfechos na fissurectomia e retalho de avanço em V­Y para o tratamento de fissura anal crônica

ABSTRACT Chronic anal fissure is difficult to treat. Surgery is usually recommended in the case of drug therapeutic failure. Fecal incontinence in patients with weaker sphincters (multipara older patients with a history of pelvic surgery etc.) is a major reason for rejecting surgery. Such these patients should be underwent fissurectomy and V-Y advancement flap in which sphincterotomy is not required. In this prospective study, we determined the outcomes and complications of fissurectomy and V-Y advancement flap in both groups of patients with low and high anal sphincter tones.

RESUMO A fissura anal crônica tem tratamento difícil. A cirurgia geralmente é recomendada em caso de falha do tratamento medicamentoso. A incontinência fecal em pacientes com esfíncteres mais fracos (pacientes multíparas mais velhas com história de cirurgia pélvica etc.) é uma razão importante para a rejeição da cirurgia. Esses pacientes devem ser submetidos a fissurectomia e retalho de avanço em V-Y no qual a esfincterotomia não é necessária. Neste estudo prospectivo, determinamos os desfechos e complicações da fissurectomia e o retalho de avanço em V-Y em ambos os grupos de pacientes com tônus baixo e alto do esfíncter anal.

TeleCondutas: fissura anal / TeleGuides: anal fissure

A fissura anal é uma laceração do revestimento do canal anal inferior. É uma das patologias benignas anorretais mais comuns e, em muitos casos, resolve-se espontaneamente. Sua prevalência é igual entre os sexos e é mais comum em adultos jovens. A grande maioria das fissuras são primárias e causadas por trauma local, como constipação, diarreia ou sexo anal. Fissuras secundárias são encontradas em pacientes com Doença de Crohn, malignidades (neoplasia epidermoide do canal anal, leucemia), tuberculose ou doenças sexualmente transmissíveis (HIV, sífilis, clamídia). Esta guia apresenta informação que orienta a conduta para casos de fissura anal no contexto da Atenção Primária à Saúde, incluindo: classificação, avaliação clínica, diagnóstico, tratamento clínico, tratamento cirúrgico e encaminhamento para especialista.

Surgery as a preferred modality of treatment for the patients of chronic anal fissure with sentinel piles

To find out the preferred modality of treatment by patients having chronic anal fissure with sentinel pile. Prospective, Observational Study. This study was conducted at the Department of Surgery, Baish General Hospital, Kingdom of Saudi Arabia from January 2008 to December 2011. Forty eight patients had chronic anal fissures associated with sentinel piles. They had been explained the multiple modalities of treatment available along with their advantages and disadvantages. Some patients preferred surgery as 1[st] line of treatment while others conservative. Lateral sphincterotomy associated with fissurectomy was the surgical procedure applied, while 0.2% GTN cream as conservative modality. Out of total 48 patients, 39 were treated by surgery [P=0.2]. Thirty two [Group-A] were treated by surgery as 1[st] line of treatment [P=0.2], while 7 [Group-C] as 2[nd] line after failure with 0.2% GTN cream [P>0.05]. Healing rate and patients' satisfaction were excellent. A total of sixteen patients [41.02%] developed different post-operative complications, out of which, one patient [2.56%] had marked bleeding. One [2.56%] had transient flatus incontinence. Eight [20.51%] suffered from severe pain treated by opiate-derivative analgesic. Six [15.38%] had urinary retention. A total of 16 patients [Group-B] were initially treated conservatively with 0.2% GTN cream [P>0.05]. Out of 16, nine [56.25%] were quite satisfied with conservative treatment, while seven [43.75%] had failure and switched to surgery as 2[nd] line of treatment. None of the modality of treatment is without complications. Lateral sphincterotomy associated with fissurectomy is an effective treatment and gives patients a sense of satisfaction to the patient to get rid of sentinel pile

Tratamiento médico de la fisura anal con tadafilo tópico como principio activo / Medical treatment of chronic anal fissure with topical tadalafil

Introducción: La fisura anal es una úlcera lineal dolorosa que generalmente, aparece en la línea media posterior del canal anal, extendiéndose desde la línea dentada hasta el margen del ano. Su persistencia se debe al espasmo anómalo del músculo del esfínter interno. Hasta hace poco, la curación definitiva de las fisuras solo se logró mediante procedimientos quirúrgicos dirigidos a la ablación del espasmo esfinteriano. Diseño: Estudio prospectivo, controlado y aleatorio para comprobar la hipótesis de que la aplicación tópica de una preparación de Tadalafilo es un método efectivo y seguro para relajar el músculo liso y promover la cicatrización de la fisura anal. Población y métodos: Se seleccionaron los pacientes que acudieron a la consulta de coloproctología del HCC con diagnóstico de fisura anal (726). Todos fueron sometidos a una historia clínica y examen físico, antes del comienzo del tratamiento y seguimiento por 1 año. Los pacientes fueron divididos en tres grupos: Grupo A: tratados de forma médica con AINES por via oral, sediluvios y pomadas tópicas de esteroides 3 veces al dia. Grupo B: tratados con nitroglicerina 0,25% locales crema 3 veces al día. Grupo C: tratados con toxina botulínica inyectada 1 sola dosis en el espesor del esfínter interno del ano. Grupo D: tratados con formula magistral crema tópica de Tadalafilo aplicada 3 veces al día. Grupo E: pacientes a quienes se les realiza la Esfinterotomía Lateral Interna una vez que se considera ha fracasado el manejo médico y tratamiento farmacológico. Resultados: Se encontró predominio del sexo femenino con 370 pacientes (50.97%). Las edades en las cual se agrupó mayor cantidad de individuos fue entre los 26 a 35 años con 218 pacientes (30,02%). Predominó el diagnóstico de fisura crónica con 382 casos (52,61 %). El tratamiento inicial que se utilizó más frecuentemente fue el quirúrgico con 270 pacientes (37,19%), seguido de Tadalafilo tópico con 196 pacientes (26,99%)...

Introduction: Anal fissure is a painful linear ulcer usually appears in the posterior midline of the anal canal, extending from the dentate line to the margin of the anus. Its persistence is due to spasm abnormal internal sphincter muscle. Until recently, a definitive cure was achieved only cracks by surgical procedures aimed at ablation of the sphincter spasm. Design: Prospective. controlled trial to test the hypothesis that topical application of a preparation of Tadalafil is a safe and effective method to relax the smooth muscle and promote healing of anal fissure. Population and methods: We selected patients who attended the consultation of Coloproctology of HCC diagnosed with anal fissure (726). AIl underwent a medical history and physical examination before starting treatment and followed for 1 year. The patients were divided into three groups: Group A: treated medical oral NSAlDs, topical ointments sediluvios and steroids 3 times a day. Group B: treated with local nitroglycerin cream 0.25% 3 times a day. Group C: treated with botulinum toxin injection 1 dose in the thickness of the internal anal sphincter. Group D: treated with topical cream formulation TadalafiI masterfully applied 3 times a day. Group E: patients who underwent lateral internal sphincterotomy is considered after failed medical management and pharmacological treatment. Results: There was a predominance of females with 370 patientes (50.97%). The ages at which more individuals grouped was between 26 to 35 years with 218 patients (30.02%). The predominant diagnosis of chronic fissure with 382 cases (52.61%). The initial treatment was most frequently used surgical treatment of 270 patients (37.19%), followed by topical Tadalafil 196 patients (26.99%). The initial treatment had less failure was the use of topical Tadalafil 10 cases (1.37%), which required surgery...

Retalhos de avanço no tratamento da fissura anal crônica: experiência inicial / Advancement flap in the treatment of chronic anal fissure: inicial experience

A fissura anal é uma laceração do canal anal relacionada ao trauma, hipertonia esfincteriana e isquemia. A maioria cicatriza espontaneamente ou com tratamento conservador, e poucas requerem tratamento cirúrgico. O objetivo deste trabalho é verificar os resultados clínicos e alterações manométricas de pacientes submetidos ao tratamento cirúrgico da fissura anal com avançamento de retalhos em v-y. Métodos: Estudo prospectivo, realizado nos anos de 2007, 2008 e 2009, que abrangeu nove pacientes portadores de fissura anal crônica submetidos ao avançamento de retalho anal. Foram avaliadas as pressões do canal anal ao repouso, contração e esforço evacuatório; no pré e pós-operatório. Resultados: Na amostra, todos os pacientes apresentaram hipertonia esfincteriana prévia. seis (66,6 por cento) obtiveram resolução total dos sintomas e das lesões. Um (11,11 por cento) sofreu deiscência parcial do retalho, sem sintomas clínicos; e outros dois (22,22 por cento), infecção com perda dos mesmos e persistência da fissura. A análise manométrica das pressões de repouso, contração e evacuação nos grupos não mostrou alteração estatisticamente significativa (p>0,05), o que comprova que a cirurgia não incluiu manipulação dos esfíncteres. Conclusão: Os retalhos anais mostraram-se efetivos no tratamento da fissura anal, com cicatrização da lesão, sem que ocorram alterações nas pressões anais desses pacientes.

The anal fissure is a laceration of the anal canal related to trauma, hypertonic sphincter and ischemia. The majority heals spontaneously or with conservative treatment and only a few requires surgical treatment. The objective of this study is to verify the clinical results and manometric alterations of patients submitted to the surgical treatment of the anal fissure with advance of v-y skin flaps. Methods: Prospective study, accomplished in 2007,2008 and 2009, in witch nine patients with chronic anal fissure were submitted to v-y advance. The pressures of the anal canal at rest, contraction and at evacuation effort were evaluated in the pre and postoperative. Results: In the sample, all the patients had presented previous hypertonic sphincter. six (66.6 percent) had gotten total resolution of the symptoms and the injuries. One (16.6 percent) suffered partial dehiscence of the flap, without clinical symptoms; and another two (22,2 percent), infection with loss of the same and persistence of the fissure. The manometric analysis of the pressures at rest, contraction and evacuation did not show significant statistical alteration (p> 0,05), what proves that the surgery did not manipulated the sphincters. Conclusion: The anal flap had revealed an effective treatment of the anal fissure with total healing of the injury, without alterations in the pressures of the sphincters.

INTRODUCTION: The anal fissure is a linear tear in the anal canal mucosa. If healing fails, it evolves into a chronic anal fissure (CAF). This is one of the most frequent proctologic problems affecting younger patients, altering their social and work life. As it is disabling disease, it causes a socioeconomic problem and, hence, it is important to make a proper diagnosis and apply a rapid and efficient treatment. At present, there are different therapeutic options, both medical and surgical. Among the first, there are several options that relax the anal sphincter. One of the options which are most used is the 0.2 per cent Glycerol Trinitrate (GTN) ointment, there being some randomized and controlled studies reporting 48 per cent and 69 per cent healing rates and other studies with comparable results against surgery. The objective was to know the results of the GTN ointment, so as to avoid surgery, and the probable permanent section of the internal anal sphincter. MATERIAL AND METHODS: Topical Glycerol Trinitrate ointment 0.2 per cent was used twice a day during two weeks. All patients diagnosed with CAF who met the inclusion criteriaparticipated in this study for a one-year period, from February 2007 to January 2008. Two controls were carried out, one at the end of the treatment to verify healing and absence of symptoms, and the other after two months to check recidivism. RESULTS: There were 19 female patients (63.3 per cent) and 11 male patients (36.7 per cent). Theaverage age was 34.87 years, with higher prevalence between 21 and 40 years (50 per cent) and minor prevalence between 41 and 50 years (13.3 per cent). The most frequent symptoms found were the association of anal pain with rectal bleeding in 66.6 per cent of the patients, followedby isolated rectal bleeding and anal pain in 23.3 per cent and 10 per cent of cases, respectively. The most common localization of the CAF was the posterior midline in 63.3 per cent of patients, ...

Lateral internal sphincterotom; [for the treatment of fissure in-ano] [six years experience]

To evaluate the efficacy of lateral internal sphincterotomy in fissure in-ano. This study is a prospective clinical trial. it was conducted initially at D.H.Q./ Allied Hospital [PMC] Faisalabad and then other centers from November 2001 to onward for the period of six years. 140 patients, in urgency due to sever pain, non-compliance to conservative and pharmacological management, or their preference were treated by lateral internal sphincterotomy. The patients were followed up at 1 st to 12th weeks. The extent of improvement in presenting symptoms and complications were noted on questionnaires. Lateral internal sphincterotomy relieved 140 [100%] patients. Transient incontinence of flatus was present in 64.3%, at 1st week that was resolved at 8-12th weeks. There was no recurrence in other complications included infection 7.1%, abscess 7.1% and anesthesia related problems in 14.2%. Lateral internal Sphincterotomy may be regarded as [The Gold Standard]

Acute anal fissure; effect of topical glyceryl trinitrate [GTN] on its management

To evaluate the role of topical glyceryl trinitrate [0.2% GTN] on the clinical features of acute anal fissure. A prospective, open label therapeutic trial was carried out at Combined Military Hospital, Kharian Cantonment during one calendar year. All adult males and females presenting with acute anal fissure were included. Patients with chronic anal fissure, associated pathology [hemorrhoids, fistula in ano], age < 15 years, previous surgery of anal canal were excluded. The diagnosis was based upon history and physical examination. A detailed history was taken regarding their symptoms like painful defecation, bleeding per rectum, constipation and itching. Then the patients were examined to look for anal fissure, associated mucus discharge and sphincter tone and recorded in the proforma. 0.2% topical GTN ointment was prescribed twice daily for local application in the anal canal with the help of cotton pledget on a stick [soaked completely in ointment]. The duration of treatment was four weeks and their symptomatology and healing of anal fissure was assessed weekly. A total of 40 patients were treated in this study. Age varied between 22 - 51 years. 36 patients [90%] were male while only 4 patients [10%] were females. Painful defecation [100%], bleeding PR [87.5%] constipation [50%], and itching [40%] were the main complaints. Posterior fissure was seen in 85%, anterior fissure in 12.5%, while both anterior and posterior fissures were seen in 2.5% of patients. Out of 40 patients 21 had complete healing of anal fissure while 03 patients recovered partially. Thus the healing rate was 60%. Topical glyceryl trinitrate is an effective treatment modality for acute anal fissure

Avaliação manométrica anal pré e pós tratamento da fissura anal crônica com nifedipina tópica 0,2 por cento / The role of nifedipine 0,2 percent in cronic anal fissure-manometric study pre and post treatment

No tratamento da fissura anal, novas drogas têm sido utilizadas, dentre elas os bloqueadores de canais de cálcio. O objetivo desta pesquisa foi à avaliação manométrica de pacientes com fissura anal crônica após tratamento com nifedipina tópica 0,2 por cento, correlacionando com a cicatrização e a dor. Trata-se de estudo prospectivo realizado em pacientes atendidos no ambulatório de Coloproctologia do Hospital Universitário de Taubaté. Os pacientes foram submetidos ao exame manométrico antes e após 30 dias da utilização de nifedipina tópica gel 0,2 por cento três vezes ao dia no ânus e margem anal. Para a análise estatística foi utilizado o teste de Mann-Whitney considerando significante, se p<0,05. Os dez pacientes não demonstraram nenhuma alteração manométrica provocada pelo tratamento com nifedipina, mas 50 por cento deles relataram melhora dos sintomas e 40 por cento dos pacientes apresentaram cicatrização da fissura, mostrando que a nifedipina foi efetiva no tratamento da fissura anal e segura do ponto de vista funcional, por não causar lesões esfincterianas. A avaliação manométrica demonstrou não haver alterações nas pressões anais demonstrando, entretanto, melhora da dor em 50 por cento e cicatrização em 40 por cento dos pacientes.

In the treatment of the anal fissure, calcium channel blockers are among the new drugs which have been used. The objective of this research was the manometric evaluation of patients with chronic anal fissure after topic treatment with 0.2 percent nifedipine and correlation with the healing and pain. This is a prospective study of patients from Coloproctology Clinic of the University of Taubaté Hospital. The patients had been submitted to a manometric examination before and after 30 days of the use of topic 0.2 percent nifedipine gel three times a day in the anus and anal edge. For the statistics analysis Mann-Whitney test was applied to a significance of p= 0,05. Ten patients did not exihibit manometric alteration associated with nifedipina treatment, however 50 percent of them reported improvement of the symptoms and 40 percent depicted healing of the fissure. The results demonstrated that nifedipine was effective and safe for anal fissure treatment and considering the functional point of view it did not cause injuries as well. The manometric evaluation did not demonstrate alterations in the anal pressure; however, it was observed that 50 percent of the patients had improvement in pain and 40 percent in healing.

Fisura anal aguda. Tratamiento convencional versus trinitrato de glicerilo / Acute anal fissure. Standard versus glyceryl trinitrate treatment

Antecedentes: El tratamiento no quirúrgico de la fisura anal aguda sigue siendo objeto de múltiples estudios. Quisimos conocer como podíamos mejorar los resultados añadiendo un donante de óxido nítrico al tratamiento convencional. Objetivo: Comparar dos tratamientos médicos para la fisura anal aguda, el tratamiento convencional versus trinitrato de glicerilo (TNG). Lugar de aplicación: Consultorios externos de coloproctología de hospitales privados. Diseño: Prospectivo, comparativo, aleatorio, multicéntrico. Población: 167 pacientes mayores de 18 años con fisura anal aguda. Método: Grupo I (TNG), n = 78. La dosis se calculó en 0,8 mg. Evaluamos efectos colaterales de la medicación y tasa de éxito. Grupo II (tratamiento convencional), n= 89. Se evaluó el dolor mediante una escala numérica al momento de la consulta y a los 3, 7 y 10 días. Resultados: El tratamiento fue insuficiente (necesidad de medicación agregada, benzodiacepinas) en 15 pacientes del grupo I y 1 paciente de este grupo necesito cirugía. Mientras que en el grupo II el tratamiento fue insuficiente en 8 pacientes (8,9 por ciento) y requirieron cirugía 12 pacientes (13 por ciento). No hubo que suspender en ningún paciente el TNG. Dentro de la evaluación del dolor vimos que gran parte del grupo I a los 3 días se situaba en el punto de menor dolor mientras que en el grupo II no hubo cambios. Conclusiones: El tratamiento con TNG es más eficaz en la tasa de curación, y es más efectivo en calmar el dolor que el tratamiento convencional.

[Botulinum toxin in treatment of chronic idiopathic anal fissure]

Anal fissure is a chronic condition characterized by painful defecation and rectal bleeding. The aim of this study was to compare the injection of botulinum toxin [BT], versus with surgical lateral internal sphincterotomy [LIS]. In this clinical trial, 40 patients enrolled with chronic idiopathic anal fissure [CIAF] and were divided into 2 groups [20 BT group and 20 LIS group]. Both groups were compared according to complications and healing process during one week, following, 2 and 4 months after interventions. There were no statistical significant differences between 2 groups as a viewpoint of duration of disease, pain and other symptoms at the beginning of the study. The rate of healing in the LIS group was greater than the BT group within the first month [16/0], and second month [16/7] [p<0.05], however, there were no significant differences between the two groups in the 4[th] month [17/11] of the study [p>0.05]. In comparison with the BT group, the severity of pain in the LIS group decreased significantly. There were no significant differences between the two groups regarding complications. Healing in the BT group was approximately similar to the LIS; yet it appears to occur slower than LIS. Therefore, according to the results of the study, injection of the BT is recommended within the first step of CIAF treatment. To obtain the maximum healing effects of BT, a minimum period of 4 months is needed

Tratamiento de la fisura anal / Treatment of the anal fissure

La fisura anal es una lesión que aparece en la porción epidérmica del canal anal, con sintomatología muy florida de dolor y sangrado defecatorio. Existen dos formas típicas, la primaria o idiopática, relacionada con la isquemia relativa del anodermo debida al incremento del tono basal esfintérico interno, y la secundaria a patologías infecciosas o del tubo digestivo. Objetivo y diseño: En los últimos años surgió el concepto de esfinterotomía química. El motivo de este trabajo es la comparación entre estas técnicas incruentas y la esfinterotomía quirúrgica, evaluando en forma prospectiva randomizada los pacientes tratados con diltiazem al 2 por ciento en vaselina sólida, trinitrato de glicerilo aplicados tópicamente y la esfinterotomía lateral interna.Material y Métodos: Durante el período comprendido entre el 31 de diciembre de 2002 y el 31 de diciembre de 2004 se trataron 174 pacientes; 56 con diltiazem al 2 por ciento, 60 con trinitrato de glicerilo y 58 por medio de esfinterotomía lateral interna 10 abierta y 48 cerrada, (Nottaras). La ubicación de la fisura fue en el 76.8 por ciento o 134 pacientes en hora VI, y en el 23.2 por ciento o 40 en hora XII. La distribución según sexo fue 96 (55.3 por ciento) varones y 78 ( 44.7 por ciento) mujeres. Resultados: Luego de una media de seguimiento de 87 días (7 a 330 días), en el grupo tratado con diltiazem, 33 pacientes presentaron la desaparición de los síntomas en la primer semana, con una curación y epitelización, sin recidiva, en 38 pacientes a las 6 semanas. 7 pacientes evolucionaron mal y necesitaron cirugía, y 9 no se presentaron al control y seguimiento.En el grupo tratado con trinitrato de glicerilo, 36 pacientes tuvieron una buena evolución, 5 necesitaron cirugía, 10 no volvieron a control y 9 suspendieron el tratamiento por reacciones adversas. El grupo de 58 pacientes tratado quirúrgicamente evolucionó favorablemente excepto 2 de ellos que necesitaron una anoplastía con deslizamiento de colgajo. Conclu...
