Pelvic floor physical therapy in the treatment of chronic anal fissure (PAF trial): quality of life outcome.

BACKGROUND: Chronic anal fissure is one of the most common anorectal diseases and is associated with reduced quality of life. The aim of this study was to investigate the effects of pelvic floor physical therapy on quality of life in patients with chronic anal fissure using the Short-Form 36 Health Survey (RAND-36). METHODS: Adult patients, with chronic anal fissure and concomitant pelvic floor dysfunction, such as dyssynergia and increased pelvic floor muscle tone, were recruited at the Proctos Clinic in the Netherlands, between December 2018 and July 2021 and randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy or assigned to a control group receiving postponed pelvic floor physical therapy (PAF trial). Quality of life and pain ratings were outcomes of the study and were measured at 8- and 20-week follow-up. RESULTS: One hundred patients (50 women and 50 men, median age 44.6 years [range 19-68 years]), completed the RAND-36 questionnaire and visual analog (VAS) pain scale score at admission. A significant improvement was found at 20-week follow-up in all domains of the RAND-36; physical functioning, pain, health change (p < 0.001); physical role, vitality, general health, social functioning, emotional role, mental health (p < 0.05). VAS pain was significantly reduced at 8 weeks (mean estimated difference 1.98; 95% CI 1.55-2.42, p < 0.001) and remained significant at 20-week follow-up (p < 0.001). The difference between the groups as regards change in the mean pain intensity scores at 8 weeks was 2.48 (95% CI - 3.20 to - 1.75; p < 0.001). Compared to the reference values of the general Dutch population, the patients in our study with a chronic anal fissure and pelvic floor dysfunction reported an impaired quality of life in 8 of 9 domains of the RAND-36. After treatment, significant lower scores were found in 2 out of 9 domains. CONCLUSIONS: The results of this study provide evidence that treatment by pelvic floor physical therapy improves quality of life and reduces pain, making it an important tool in management of chronic anal fissure and concomitant pelvic floor dysfunction.

Fissurectomy versus lateral internal sphincterotomy in the treatment of chronic anal fissures: no advantages in terms of post-operative incontinence.

PURPOSE: The standard treatment for chronic anal fissures that have failed non-operative management is lateral internal sphincterotomy. Surgery can cause de novo incontinence. Fissurectomy has been proposed as a sphincter/saving procedure, especially in the presence of a deep posterior pouch with or without a crypt infection. This study investigated whether fissurectomy offers a benefit in terms of de novo post-operative incontinence. METHODS: Patients surgically managed with fissurectomy or lateral internal sphincterotomy for chronic anal fissures from 2013 to 2019 have been included. Healing rate, changes in continence and patient satisfaction were investigated at long-term follow-up. RESULTS: One hundred twenty patients (55 females, 65 males) were analysed: 29 patients underwent fissurectomy and 91 lateral internal sphincterotomy. Mean follow-up was 55 months [confidence interval (CI) 5-116 months]. Both techniques showed some rate of de novo post-operative incontinence (> +3 Vaizey score points): 8.9% lateral internal sphincterotomy, 17.8% fissurectomy (p = 0.338). The mean Vaizey score in these patients was 10.37 [standard deviation (sd) 6.3] after lateral internal sphincterotomy (LIS) and 5.4 (sd 2.3) after fissurectomy Healing rate was 97.8% in the lateral internal sphincterotomy group and 75.8% in the fissurectomy group (p = 0.001). In the lateral internal sphincterotomy group, patients with de novo post-op incontinence showed a statistically significant lower satisfaction rate (9.2 ± 1.57 versus 6.13 ± 3; p = 0.023) while no differences were present in the fissurectomy group (8.87 ± 1.69 versus 7.4 ± 1.14; p = 0.077). CONCLUSIONS: Lateral internal sphincterotomy is confirmed as the preferred technique in term of healing rate. Fissurectomy did not offer a lower rate of de novo post-operative incontinence, but resulted in lower Vaizey scores in patients in whom this occurred. Satisfaction was lower in patients suffering a de novo post-operative incontinence after lateral internal sphincterotomy.

Perianal Application of Glyceryl Trinitrate Ointment Versus Tocopherol Acetate Ointment in the Treatment of Chronic Anal Fissure: A Randomized Clinical Trial.

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.

Pelvic floor physical therapy in patients with chronic anal fissure: a randomized controlled trial.

BACKGROUND: A chronic anal fissure is a common, painful condition with great impact on daily life. The exact pathogenesis has not been fully elucidated and treatment varies. A large percentage of patients experience pelvic floor dysfunction (dyssynergia and increased pelvic floor muscle tone). The aim of our study was to investigate the effect of pelvic floor physical therapy in patients with chronic anal fissure. METHODS: Between December 2018 and July 2021, at the Proctos Clinic in the Netherlands, patients with chronic anal fissure and pelvic floor dysfunction were randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy including electromyographic biofeedback or assigned to a control group receiving postponed pelvic floor physical therapy. The primary outcome was muscle tone at rest during electromyographic registration of the pelvic floor before and after pelvic floor physical therapy. Secondary outcomes contained healing of the fissure, pain ratings, improvement of pelvic floor function, and complaint reduction measured with a proctology-specific patient-reported outcome measurement. Endpoints were measured at 8- and 20-week follow-up. RESULTS: One hundred forty patients were included in the study, 68 men (48.6%) and 72 women (51.4%) with a mean age of 44.5 ± 11.1 (range 19-79) years. Mean resting electromyographic values of the pelvic floor in the intervention group significantly improved from pre- to post-treatment (p < 0.001) and relative to controls (mean estimated difference between groups - 1.88 µV; 95% CI, - 2.49 to - 1.27 (p < 0.001) at first follow-up and remained significant from baseline at 20-week follow-up (p < 0.001). The intervention group performed better compared to the control group on all secondary outcomes, i.e., healing of the fissure (55.7% of the patients vs 21.4% in control, pain ratings (p < 0.001), diminished dyssynergia (p < 0.001), complaint reduction (p < 0.001), and decrease of pelvic floor muscle tone (p < 0.05) at first follow-up. CONCLUSIONS: The findings of this study provide strong evidence that pelvic floor physical therapy is effective in patients with chronic anal fissure and pelvic floor dysfunction and supports its recommendation as adjuvant treatment besides regular conservative treatment.

Short-term Results of Platelet-Rich Plasma in the Treatment of Chronic Anal Fissure: Randomized Controlled Clinical Study.

BACKGROUND: Anal fissure is one of the most common benign anal disorders, and medical treatments play an important role in its management. OBJECTIVE: The purpose of this study was to investigate the short-term effects and success of platelet-rich plasma in the treatment of chronic anal fissure. DESIGN: The study is a 2 parallel group, randomized, controlled clinical trial. SETTINGS: The study was performed in 2 tertiary university hospitals. PATIENTS: Forty-four patients with chronic anal fissure were randomly assigned to platelet-rich plasma treatment or control group. Presenting symptoms and pain scores were recorded on enrollment. The control patient self-administered topical glyceryl trinitrate. Platelet-rich plasma was injected locally in the intervention group followed by self-administered glyceryl trinitrate. MAIN OUTCOME MEASURES: The primary outcome measure is a reduction in pain scores. RESULTS: On day 10 and 1 month after treatment, the mean pain score was significantly lower in the patients treated with platelet-rich plasma than in the controls (p = 0.005 and p < 0.005). By 1 month after treatment, the mean pain score declined by 5.7 points in the platelet-rich plasma-treated group compared with a 4.1 mean pain score decline in the control group (mean difference:1.6 points (95% CI, 0.3-2.9)). According to the repeated-measures analyses, pain scores decreased in both groups, but the decrease in the treatment group was statistically higher than in the control group (p < 0.001). Complete epithelialization and recovery rates were significantly higher in the platelet-rich plasma group than in controls at all follow-up times, with p values ranging from 0.034 to <0.001. The observed difference in complete epithelialization after 2 months of treatment between the platelet-rich plasma group and the control group was 56.2% with a 95% CI of 14.03% to 98.4%. LIMITATIONS: This study was limited by its small sample size, and long-term follow-up of the patients was not presented. CONCLUSIONS: Platelet-rich plasma reduced concerns and accelerated epithelialization and healing in patients with chronic anal fissures.

ANTECEDENTES: La fisura anal es uno de los trastornos anales benignos más comunes y los tratamientos médicos juegan un papel importante en su manejo. OBJETIVO: El propósito de este estudio fue investigar los efectos a corto plazo y el éxito del plasma rico en plaquetas en el tratamiento de la fisura an33al crónica. DISEO: El estudio es un ensayo clínico controlado, aleatorizado y de dos grupos paralelos. ESCENARIO: El estudio se llevó a cabo en dos hospitales universitarios terciarios. PACIENTES: Cuarenta y cuatro pacientes con fisura anal crónica fueron asignados aleatoriamente al grupo de tratamiento con plasma rico en plaquetas o al grupo control. Los síntomas de presentación y las puntuaciones de dolor se registraron en la inscripción. Los pacientes de control se autoadministraron trinitrato de glicerilo tópico. El plasma rico en plaquetas se inyectó localmente en el grupo de intervención seguido de trinitrato de glicerilo autoadministrado. PRINCIPALES MEDIDAS DE RESULTADO: La principal medida de resultado es una reducción en las puntuaciones de dolor. RESULTADOS: El día 10 y un mes después del tratamiento, la puntuación media de dolor fue significativamente menor en los pacientes con plasma rico en plaquetas que en los controles (p = 0.005 y p <0.005, respectivamente). Un mes después del tratamiento, la puntuación media de dolor disminuyó 5.7 puntos en el grupo tratado con plasma rico en plaquetas en comparación con una disminución de la puntuación media de dolor de 4.1 en el grupo de control (diferencia media: 1.6 puntos [intervalo de confianza del 95%; 0.3-2.9] Según los análisis de medidas repetidas, las puntuaciones de dolor disminuyeron en ambos grupos, pero la disminución en el grupo de tratamiento fue estadísticamente mayor que en el grupo de control (p <0.001). Las tasas de epitelización completa y recuperación fueron significativamente más altas en los pacientes con plasma rico en plaquetas que en los controles en todos los tiempos de seguimiento, con valores de p que van desde 0.034 a <0.001. La diferencia observada en la epitelización completa después de dos meses de tratamiento entre el grupo de plasma rico en plaquetas y el grupo de control fue del 56.2% con un intervalo de confianza del 95% del 14.03% al 98.4%. LIMITACIONES: Este estudio estuvo limitado por el pequeño tamaño de la muestra y porque no se proporcionó un seguimiento a largo plazo de los pacientes. CONCLUSIONES: El plasma rico en plaquetas redujo las molestias y aceleró la epitelización y la curación en pacientes con fisuras anales crónicas.

The role of percutaneous tibial nerve stimulation (PTNS) in the treatment of chronic anal fissure: a systematic review.

PURPOSE: This study was designed to summarize the current evidence regarding the role of percutaneous tibial nerve stimulation (PTNS) in the treatment of chronic anal fissure (CAF). METHODS: The present systematic review of the literature was conducted on the basis of the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The primary endpoint of our study was the CAF recurrence rate. Quality assessment was based on the RoB 2 tool and the Case Series Quality Checklist. RESULTS: Overall, 5 studies and 102 patients were included. A considerably heterogeneity in the neuromodulation technique and setting was identified. The pooled recurrence rate was estimated at the level of 19% (16/84). Post-interventional pain and Wexner scores were considerably reduced. The 2-month healing rate was 72% (18/25), whereas 73.6% of patients were symptom-free at 6 months. CONCLUSIONS: PTNS is an effective alternative for the non-operative management of CAF. Due to several limitations further larger and higher quality studies are required.

Anal fissure management by the gastroenterologist.

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.

Recommendations of the Crohn's Disease and Ulcerative Colitis Spanish Working Group (GETECCU) for the treatment of perianal fistulas of Crohn's disease. / Recomendaciones del Grupo Español de Trabajo de Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) para el tratamiento de las fístulas perianales de la enfermedad de Crohn.

Recommendations are advice that is given and considered to be beneficial; however, they are still suggestions and are therefore open to different interpretations. In this sense, the final objective of the review has been to try to homogenize, with the evidence available, the approach to the diagnosis and medical/surgical treatment of one of the most complex manifestations of Crohn's disease, such as simple and complex perianal fistulas.

Perianal Tuberculosis: Lessons Learned in 57 Patients From 743 Samples of Histopathology and Polymerase Chain Reaction and a Systematic Review of Literature.

BACKGROUND: Few data are published on perianal tuberculosis. OBJECTIVE: This study aimed to determine the best method to diagnose tuberculosis in patients with fistula-in-ano and to conduct a systematic review to determine the incidence and characteristics of tuberculosis fistula-in-ano. DATA SOURCES: The prospective study data and existing literature were derived from PubMed, Google scholar, and Scopus STUDY SELECTION:: Prospective analysis of patients with tuberculous fistula-in-ano treated between 2014 and 2018 was conducted, and a systematic review of studies describing ≥3 patients with tuberculosis fistula-in-ano was completed. INTERVENTION: Testing of tuberculosis was performed by histopathology or polymerase chain reaction of tissue or pus from the fistula tract. MAIN OUTCOME MEASURES: The primary outcomes measured were the detection rate of various tests to detect tuberculosis in fistula-in-ano and the prevalence rate of tuberculosis in simple versus complex fistulas. RESULTS: In 637 samples (410 patients) tested, tuberculosis was detected in 49 samples (43 patients). Additional samples (n = 106) sent in patients with a high index of suspicion tested positive in 14 more patients. Thus, overall, 63 samples tested positive in 57 patients (total: 743 samples in 410 patients were tested). Tuberculosis was detected in 2 of 181 patients (1.1%) in tissue (histopathology), in 28 of 341 patients (8.2%) in tissue (polymerase chain reaction), and in 19 of 115 patients (16.5%) in pus (polymerase chain reaction) samples. To detect tuberculosis, tissue (polymerase chain reaction) was significantly better than tissue (histopathology) (28/341 vs 2/181, p < 0.00001) and pus (polymerase chain reaction) was significantly better than tissue (polymerase chain reaction) (19/115 vs 28/341, p < 0.0009). Tuberculosis was significantly more common in complex fistulas than in simple fistulas (20.3% vs 7.2%, p = 0.0002). The systematic review (n = 199) highlighted that tubercular fistulas are more common in recurrent and complex fistulas and in tuberculosis endemic regions. LIMITATIONS: The true sensitivity and specificity of each testing modality could not be determined because not all patients with tuberculosis fistula-in-ano were tested by every diagnostic modality studied. CONCLUSIONS: The tuberculosis detection rate of polymerase chain reaction was significantly higher than histopathology. Among polymerase chain reaction, pus had higher detection rate than tissue. Tuberculosis was associated with more complex and recurrent fistulas.

Percutaneous tibial nerve stimulation (PTNS): an alternative treatment option for chronic therapy resistant anal fissure.

BACKGROUND: The aim of the present study was to evaluate percutaneous tibial nerve stimulation (PTNS) for treatment resistant chronic anal fissure. METHODS: Consecutive patients with chronic anal fissure were treated with neuromodulation via the posterior tibial nerve between October 2013 and January 2014. Patients had PTNS for 30 min on 10 consecutive days. All patients had failed conventional medical treatment. The visual analogue scale (VAS) score, St. Marks score, Wexner's constipation score, Brief Pain Inventory (BPI-SF), bleeding and mucosal healing were evaluated before treatment, at termination, after 3 months, and then yearly for 3 years. RESULTS: Ten patients (4 males and 6 females; mean age 49.8 years) were identified but only 9 were evaluated as one patient's fissure healed before PTNS was started. At 3-year follow-up, fissures had remained completely healed in 5 out of 9 patients. All patients stopped bleeding and were almost completely pain-free at 3 years (VAS p = 0.010) and pain relief improved from 50% at completion to 90% at 3 years. The patients' Wexner constipation scores improved significantly (p = 0.007). CONCLUSIONS: In this small series, PTNS enhanced healing of chronic anal fissure and reduced pain and bleeding with an associated improvement in bowel function.

What every PA needs to know about anorectal pain.

[Experience of using an individual approach in the anal fissures treatment]. / Opyt ispol'zovaniia individual'nogo podkhoda v lechenii anal'nykh treshchin.

AIM: To objectify the criteria for choosing the method of treatment of anal fissures, to determine the indications for surgery and sphincterotomy. MATERIAL AND METHODS: The results of treatment of 206 patients with chronic and acute anal fissures between the ages of 17 to 75 years are analyzed. The posterior anal fissure was detected in 175 (84.9%) patients, the front - in 18 (8.7%), the combination of fissures was noted 13 (6.3%) times. The history of the disease - from 1 month to 12 years. The examination included analysis of clinical data, indicators of pre- and postoperative anorectal manometry, endorectal ultrasound. The period of postoperative monitoring is from 6 to 12 months, control examinations with a functional study of the anal sphincters were carried out 1 and 2 months after healing. Concomitant hemorrhoids were noted in 65 (31.5%) patients, of which 20 (9.7%) patients were simultaneously hemorrhoidectomized. In 11 (5.3%) patients, simultaneous operations were performed in the presence of paraproctitis, rectal fistula. RESULTS: In 77.8% of patients with acute fissures, the use of conservative therapy, which included myotropic antispasmodics and local application of glycerol trinitrate made it possible to achieve healing of fissures without surgery. Operated 185 (89.8%) patients. With an increase in the basal anal pressure at the level of the internal sphincter, an increase in the average pressure in the anal canal, a decrease in the amplitude and duration of the rectoanal reflex, the indications for dosed sphincterotomy were determined in 167 patients. At the same time, in 117 persons, the excision of fissures was supplemented with a lateral 'closed' sphincterotomy, in 50 cases the posterior 'open' dosed sphincterotomy was performed. In 18 (9.7% of the operated ones) patients in the absence of sphincter hypertonus, the fissures were excised without sphincterotomy. The best functional results were obtained after performing the lateral 'closed' subcutaneous sphincterotomy. It was noticed that in the absence of characteristic complaints and clinical manifestations of incontinence, in 14 patients there was a decrease in the average pressure in the anal canal at rest and with volitional contraction. At the same time, 6 patients out of 14 belonged to the older age groups, and in 9 women there was a rectocele, pelvic floor prolapse. Postoperative incontinence was not observed. Recovery with complete epithelialization of the anoderm defect and the absence of complaints was achieved in 191 (92.7%) patients, satisfactory results (healing of fissures in the presence of pain or proctitis) - in 8 (3.9%) and in 7 (3.4%) patients relapse of the disease was noted with the ineffectiveness of therapy. CONCLUSION: The ineffectiveness of complex conservative treatment for more than two weeks, with a history of more than 3 months, is an indication for surgical treatment. Preoperative functional and clinical and physiological examination of patients allows the formation of surgical tactics. A differentiated approach to the choice of treatment method, as well as individual determination of indications for surgery and sphincterotomy can improve long-term results. The technique of simultaneous operations with the combination of anal fissure and other proctological diseases needs to be improved.

The Effect of Nonoperative Management of Chronic Anal Fissure and Hemorrhoid Disease on Bowel Function Patient-Reported Outcomes.

BACKGROUND: Nonoperative management has been reported to decrease symptoms from common anorectal conditions such as chronic anal fissures and hemorrhoids. The effects of these interventions on bowel function are unknown. OBJECTIVE: This study aims to perform a prospective evaluation of patient-reported outcomes of bowel function on nonoperative management for chronic anal fissures and hemorrhoid disease. DESIGN: This is a prospective, observational study. SETTINGS: Patient-reported outcome measures were collected from the clinical practice of the division of colon and rectal surgery at a tertiary colon and rectal surgery referral center. INTERVENTION: All patients received standardized dietary counseling including fiber supplementation as well as toileting strategies. Those with chronic anal fissures were also prescribed topical calcium channel blockers. The Colorectal Functional Outcome questionnaire was administered at baseline and at first follow-up visit. MAIN OUTCOME MEASURES: The primary outcomes measured were the mean change in patient-reported bowel function scores after nonoperative management for each disease and in aggregate. RESULTS: A cohort of 64 patients was included, 37 patients (58%) with chronic anal fissure and 27 patients with hemorrhoid disease. Incontinence, social impact, stool-related aspects, and the global score were observed to have statistically significant improvement in the aggregate group. When analyzed by diagnosis, hemorrhoid disease demonstrated a statistically significant improvement in incontinence and stool-related aspects, whereas chronic anal fissure was associated with a statistically significant change in social impact, stool-related aspects, and the global score. LIMITATIONS: This study was limited by the small cohort size and unclear patient adherence to medical management. CONCLUSIONS: Nonoperative management of chronic anal fissures and hemorrhoid disease is associated with significant improvement in patient-reported outcome scores in several domains, suggesting that dietary counseling and medical therapy should be the first-line outpatient therapy for these diseases.

Conservative Management of Chronic Anal Fissure. Results of a Case Series at 2-years Follow-up and Proposition of a New Classification.

BACKGROUND: Anal fissure is a common proctological condition that is usually defined as an anodermal ulcerative process starting from the posterior commissure to the dentate line. The objective of this study was to evaluate the resolution rate of anal fissure through the use of conservative management in patients grouped according to our newly proposed classification. A secondary purpose was to quantify the recurrence rates at 2-years follow-up in each group. METHODS: A retrospective analysis was carried out on patients in our general database. Diagnosis was based on symptoms, clinical observation, anal manometry and transanal ultrasounds. After application of inclusion and exclusion criteria, patients were assigned to different groups. Follow-up was carried out at 3, 6, 12 and 24 months. RESULTS: A total of 136 patients (54 female and 82 male) were included in the statistical analysis. At the end of the treatment period, all patients in groups 1 and 2 had a complete resolution of illness and a normal basal sphincterial tone, while those in groups 3 and 4 had a higher rate of recurrence at the 2-year follow-up. CONCLUSION: Based on our series, we propose a definitive non-surgical management for all group 1 and 2 anal fissures according to our protocol. For groups 3 and 4, we recommend a primary non-surgical approach with follow-up. This was a retrospective study and further randomized controlled studies will be necessary to confirm our results.

Percutaneous Posterior Tibial Nerve Stimulation vs Perianal Application of Glyceryl Trinitrate Ointment in the Treatment of Chronic Anal Fissure: A Randomized Clinical Trial.

BACKGROUND: Current therapeutic guidelines for the treatment of chronic anal fissure establish a medical approach as the first step. Glyceryl trinitrate ointment is the most popular of the available topical treatments in Spain but it is associated with the appearance of headache. OBJECTIVE: The purpose of this study was to compare the compliance rate among patients receiving glyceryl trinitrate treatment for chronic anal fissure with that among patients receiving percutaneous posterior tibial nerve stimulation. DESIGN: This was a prospective randomized study. SETTINGS: The study was conducted at Garcilaso Clinic (Madrid, Spain). PATIENTS: Subjects with persistent anal fissure despite hygiene and dietary measures applied over at least a 6-week period were included. INTERVENTIONS: Study interventions were perianal application of glyceryl trinitrate ointment (twice daily for 8 weeks) and percutaneous posterior tibial nerve stimulation (30-minute session 2 days per week for 8 weeks). MAIN OUTCOME MEASURES: Compliance with the treatment and healing rate of chronic anal fissure in patients receiving glyceryl trinitrate ointment or undergoing percutaneous posterior tibial nerve stimulation were evaluated. RESULTS: Forty patients were included in each group. In the glyceryl trinitrate ointment group, 15% of the patients discontinued treatment because of disabling headaches. There were no adverse effects or treatment withdrawals in the percutaneous posterior tibial nerve stimulation group (p = 0.033). After 8 weeks of treatment, the healing rate in the percutaneous posterior tibial nerve stimulation group was 87.5% vs 65.0% in the glyceryl trinitrate ointment group (p = 0.018). LIMITATIONS: Because the patients were not blinded to the treatment, we cannot rule out a placebo effect derived from the needle insertion in the percutaneous posterior tibial nerve stimulation group. CONCLUSIONS: Percutaneous posterior tibial nerve stimulation is a safe and effective alternative that is in some ways superior to glyceryl trinitrate ointment for the treatment of chronic anal fissure.

A novel method for treatment of chronic anal fissure: adipose-derived regenerative cells - a pilot study.

AIM: The purpose of this study was to investigate the safety and feasibility of autologous adipose-derived regenerative cells (ADRC) in the treatment of chronic anal fissure. METHOD: A prospective pilot study was conducted in six patients with chronic anal fissures at the First Surgical Clinic, Clinical Center of Serbia and at the BelPrime Clinic, Belgrade, Serbia. All patients were candidates for surgical treatment. The average duration of symptoms was 24 months. Pain assessment was quantified using a visual analogue scale and bowel continence was assessed using the Wexner incontinence score. Both were assessed before treatment and during each postoperative outpatient visit. Liposuction was performed under local or general anaesthesia. Extraction of ADRC was achieved with a closed automated medical device. The fat and ADRC were injected subcutaneously into the edge of the fissure. The rest of the pellet was infiltrated into the internal anal sphincter. The study has been registered at ClinicalTrials.gov (NCT02628522). RESULTS: Complete healing of the anal fissure and the disappearance of symptoms was achieved in all patients. The average time to complete pain cessation was 33.7 ± 15.0 days. All fissures healed after 3 months and remained healed 12 months after the procedure. There were no complications related to the procedure. CONCLUSION: The application of ADRC may be an alternative to lateral sphincterotomy and a reliable procedure which avoids faecal incontinence.

A systematic review and meta-analysis of the treatment of anal fissure.

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.
