The Italian Unitary Society of Colon-proctology (SIUCP: Società Italiana Unitaria di Colonproctologia) guidelines for the management of anal fissure.

INTRODUCTION: The aim of these evidence-based guidelines is to present a consensus position from members of the Italian Unitary Society of Colon-Proctology (SIUCP: Società Italiana Unitaria di Colon-Proctologia) on the diagnosis and management of anal fissure, with the purpose to guide every physician in the choice of the best treatment option, according with the available literature. METHODS: A panel of experts was designed and charged by the Board of the SIUCP to develop key-questions on the main topics covering the management of anal fissure and to performe an accurate search on each topic in different databanks, in order to provide evidence-based answers to the questions and to summarize them in statements. All the clinical questions were discussed by the expert panel in different rounds through the Delphi approach and, for each statement, a consensus among the experts was reached. The questions were created according to the PICO criteria, and the statements developed adopting the GRADE methodology. CONCLUSIONS: In patients with acute anal fissure the medical therapy with dietary and behavioral norms is indicated. In the chronic phase of disease, the conservative treatment with topical 0.3% nifedipine plus 1.5% lidocaine or nitrates may represent the first-line therapy, eventually associated with ointments with film-forming, anti-inflammatory and healing properties such as Propionibacterium extract gel. In case of first-line treatment failure, the surgical strategy (internal sphincterotomy or fissurectomy with flap), may be guided by the clinical findings, eventually supported by endoanal ultrasound and anal manometry.

Incidence and Characterization of Rectal Complications From Fecal Management Systems.

BACKGROUND: Fecal management systems have become ubiquitous in hospitalized patients with fecal incontinence or severe diarrhea, especially in the setting of perianal wounds. Although fecal management system use has been shown to be safe and effective in initial series, case reports of rectal ulceration and severe bleeding have been reported, with a relative paucity of clinical safety data in the literature. OBJECTIVE: The purpose of this study was to determine the rate of rectal complications attributable to fecal management systems, as well as to characterize possible risk factors and appropriate management strategies for such complications. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at a large academic medical center. PATIENTS: All medical and surgical patients who underwent fecal management system placement from December 2014 to March 2017 were included. MAIN OUTCOME MEASURES: We measured any rectal complication associated with fecal management system use, defined as any rectal injury identified after fecal management system use confirmed by lower endoscopy. RESULTS: A total of 629 patients were captured, with a median duration of fecal management system use of 4 days. Overall, 8 patients (1.3%) experienced a rectal injury associated with fecal management system use. All of the patients who experienced a rectal complication had severe underlying comorbidities, including 2 patients on dialysis, 1 patient with cirrhosis, and 3 patients with a recent history of emergent cardiac surgery. In 3 patients the bleeding resolved spontaneously, whereas the remaining 5 patients required intervention: transanal suture ligation (n = 2), endoscopic clip placement (n = 1), rectal packing (n = 1), and proctectomy in 1 patient with a history of pelvic radiotherapy. LIMITATIONS: The study was limited by its retrospective design and single institution. CONCLUSIONS: This is the largest study to date evaluating rectal complications from fecal management system use. Although rectal injury rates are low, they can lead to serious morbidity. Advanced age, severe comorbidities, pelvic radiotherapy, and anticoagulation status or coagulopathy are important factors to consider before fecal management system placement.

INCIDENCIA Y CARACTERIZACIN DE LAS COMPLICACIONES RECTALES DE LOS SISTEMAS DE MANEJO FECAL: ANTECEDENTES:Los sistemas de manejo fecal se han vuelto omnipresentes en pacientes hospitalizados con incontinencia fecal o diarrea severa, especialmente en el contexto de heridas perianales. Aunque se ha demostrado que el uso del sistema de tratamiento fecal es seguro y eficaz en la serie inicial, se han notificado casos de ulceración rectal y hemorragia grave, con una relativa escasez de datos de seguridad clínica en la literatura.OBJETIVO:Determinar la tasa de complicaciones rectales atribuibles a los sistemas de manejo fecal. Caracterizar los posibles factores de riesgo y las estrategias de manejo adecuadas para tales complicaciones.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLINICO:Centro médico académico de mayor volumen.PACIENTES:Todos los pacientes médicos y quirúrgicos que se sometieron a la colocación del sistema de manejo fecal desde diciembre de 2014 hasta marzo de 2017.PRINCIPALES MEDIDAS DE VALORACION:Cualquier complicación rectal asociada con el uso del sistema de manejo fecal, definida como cualquier lesión rectal identificada después del uso del sistema de manejo fecal confirmada por endoscopia baja.RESULTADOS:Se identificaron un total de 629 pacientes, con una duración media del uso del sistema de manejo fecal de 4,0 días. En general, 8 (1,3%) pacientes desarrollaron una lesión rectal asociada con el uso del sistema de manejo fecal. Todos los pacientes que mostraron una complicación rectal tenían comorbilidades subyacentes graves, incluidos dos pacientes en diálisis, un paciente con cirrosis y tres pacientes con antecedentes recientes de cirugía cardíaca emergente. En tres pacientes el sangrado se resolvió espontáneamente, mientras que los cinco pacientes restantes requirieron intervención: ligadura de sutura transanal (2), colocación de clip endoscópico (1), taponamiento rectal (1) y proctectomía en un paciente con antecedentes de radioterapia pélvica.LIMITACIONES:Diseño retrospectivo, institución única.CONCLUSIONES:Este es el estudio más grande hasta la fecha que evalúa las complicaciones rectales del uso del sistema de manejo fecal. Si bien las tasas de lesión rectal son bajas, pueden provocar una morbilidad grave. La edad avanzada, las comorbilidades graves, la radioterapia pélvica y el estado de anticoagulación o coagulopatía son factores importantes a considerar antes de la colocación del sistema de manejo fecal.

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.

Management of chronic anal fissure: results of a national survey among gastrointestinal surgeons in the Netherlands.

BACKGROUND: Chronic anal fissure (CAF) is a common, bothersome condition frequently accompanied by pelvic floor complaints. Despite current guidelines, optimal management is challenging. The aim of this study is to evaluate current management of CAF among gastrointestinal surgeons in the Netherlands. METHODS: Dutch gastrointestinal surgeons and residents were sent a survey invitation by email, which was available online between June 2021 and September 2021. The questionnaire consisted of 21 questions concerning work experience, physical examination, diagnostic and surgical techniques, and follow-up. RESULTS: Overall, 106 (33%) respondents completed the survey. Most respondents (59%) had at least 10 years of experience in treating CAF. Only 23% always addressed pelvic floor complaints. Fifty-one percent performed digital rectal examination and 22% always, or almost always, examined the pelvic floor muscles. Most respondents started treatment with fibers and/or laxatives and ointment (96%). Diltiazem was in 90% the preferred ointment. Twenty-two percent referred patients for pelvic floor physical therapy. Botulinum toxin was in 54% performed under general or spinal anesthesia or sedation. The surgical procedure of choice was fissurectomy (71%) followed by lateral internal sphincterotomy (27%). Fissurectomy was in 51% always combined with botulinum toxin. Fifty-seven percent of the respondents preferred a physical follow-up appointment. CONCLUSION: Guideline recommendations are largely followed in the Netherlands, starting with conservative measures followed by surgical procedures. Surgeons do not consistently assess pelvic floor complaints, nor do they routinely examine the pelvic floor muscles. Awareness of pelvic floor dysfunctions is important to refer patients for pelvic floor physical therapy.

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 REALISE score: a new statistically validated scoring system to assess the severity of anal fissures.

BACKGROUND: Anal fissure (AF) is a common, painful disease that strongly affects patients' quality of life, however, no scoring system to assess the severity of AF is available in the literature. The aim of this study was to set up and validate a reliable scoring system to quantify the severity of AF, to be used in prospective trials comparing the efficacy and the outcomes of surgical or medical treatments. METHODS: The study was conducted on patients with acute or chronic AF and a control group in a tertiary centre for coloproctology in June 2020-September 2020. Two researchers independently carried out a structured interviewer-led questionnaire at two different time points (T1/T2). The questionnaire consisted of five items selected according to the most commonly reported symptoms for AF: the item pain, was scored from 0 to 10 using a visual analogue scale, and quality of life, duration of pain, use of painkillers, and bleeding were scored from 1 to 5 using Likert-scale questions. The scoRing systEm for AnaL fIsSurE (REALISE) score was the sum of the points. Patients with AF and a control group of patients with haemorrhoids, anal fistula, or obstructed defecation syndrome entered the study. Main outcome measures were reliability, inter-/intraobserver agreement, and repeatability. RESULTS: One hundred and fifty well-matched patients (75 with AF and 75 controls) were enrolled. A significant difference was found between the mean REALISE score for patients with AF and controls (p < 0.001). The two REALISE scores were highly correlated (r = 0.99). The coefficient of repeatability was 1.45 in T1 and 1.18 in T2. CONCLUSIONS: The REALISE score may have an important role in the assessment and management of AF, in grading the severity of AF and comparing results of different treatments.

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.

[A case of "early" syphilis]. / Une syphilis « précoce ¼.

INTRODUCTION: Syphilis mainly affects men who have sex with men (MSM) between the ages of 20 and 49. Herein we report a case in a teenager illustrating extension of the epidemic to other populations. PATIENTS AND METHODS: A 15-year-old boy consulted in May 2018 for an anal fissure and painful oral erosions. He reported having had unprotected anal sex with another male teenager of the same age three months earlier. Syphilis serology was positive, with a positive treponemal test (TT) and non-treponemal test (VDRL) at 1/128. A treponemal bacterial DNA PCR assay was also positive for swabs obtained from the oral erosions and anal fissure. Due to a history of allergy to penicillin the patient was treated with doxycycline 200mg daily for 14 days. One month later, the mucosal lesions had subsided, and 3 months later the VDRL titer had decreased by 2 dilutions. CONCLUSION: This case of "early" syphilis illustrates a change in the French epidemiology of sexually transmitted diseases (STIs). STIs currently affect very young and previously unexposed metropolitan French populations. These infections are increasing in teenagers due to an increase in high-risk sexual behavior associated with a lack of knowledge of STIs. This case is a reminder of the current decline in the level of knowledge about STIs among teenagers as compared to young people of the same age in the 1990s.

Colorectal Surgery Review for Primary Care Providers.

Anorectal conditions are one of the most common problems evaluated by primary care physicians. Most patients present with rectal pain, rectal bleeding, or purulent drainage per rectum. Colorectal conditions have overlapping symptoms. Thorough history and careful anorectal examination can differentiate common anorectal conditions like hemorrhoids, anorectal abscesses, anal fistula, anal fissure, and anal condyloma. Most of these conditions can be diagnosed and treated without imaging.

Evaluating the Accuracy of Hemorrhoids: Comparison Among Specialties and Symptoms.

BACKGROUND: A large proportion of patients with anorectal complaints are referred to colorectal surgeons with the label of hemorrhoids. OBJECTIVE: The purpose of this study was to review presenting symptoms and frequency of accurate diagnosis, as well as to analyze determinants of misdiagnosis to guide educational endeavors. DESIGN: This was a retrospective study. SETTINGS: The study was conducted at a tertiary care academic center. PATIENTS: The charts of patients referred to a colorectal clinic with the diagnosis of hemorrhoids from January 1, 2012, to January 1, 2017, were reviewed. MAIN OUTCOME MEASURES: The accuracy of the referring provider's diagnosis of hemorrhoids was measured. RESULTS: Review of charts identified 476 patients with the referral diagnosis of hemorrhoids. The most common presenting symptoms were bleeding (63%; n = 302), pain (48%; n = 228), and protrusion (39%; n = 185). Anal examination (ie, external inspection and/or digital internal examination) was documented in only 48%. The hemorrhoid diagnostic accuracy was 65% (n = 311). Among patients with incorrect hemorrhoid diagnoses (35%; n = 169), actual diagnosis was anal fissure (34%), skin tag (27%), and hypertrophied papilla (6%). One rectal and 2 anal carcinomas were found (0.63%). Compared with general practitioners, gastroenterologists had 86% higher odds of correct diagnosis (OR = 1.86 (95% CI, 1.10-3.10); p = 0.02), whereas the gynecologists had 68% lower odds of correct diagnosis at the time of referral (OR = 0.32 (95% CI, 0.10-0.80); p = 0.02). On multivariable analysis, referring specialty was not predictive of accurate diagnosis. Patients presenting with protrusion had 73% higher odds of accurate diagnosis (OR = 1.7 (95% CI, 1.1-2.7); p = 0.02), whereas patients presenting with pain (OR = 1.6 (95% CI, 1.1-2.5); p = 0.03) or pruritus (OR = 2.5 (95% CI, 1.2-5.0); p = 0.008) were more likely to be misdiagnosed. LIMITATIONS: This is a retrospective study. Not all of the charts contained all data points. The number of patients may limit the power of the study to detect some differences. CONCLUSIONS: A variety of anorectal complaints are diagnosed as hemorrhoids by providers who have initial contact with the patients. Educational programs directed toward improving physician knowledge can potentially improve diagnostic accuracy and earlier initiation of appropriate care. Presenting symptoms other than protrusion lead to higher rate of misdiagnosis by a referring physician. See Video Abstract at http://links.lww.com/DCR/A847.

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.

What every PA needs to know about anorectal pain.

Anorectal pain is common but often misdiagnosed, and patients may suffer in silence if they are too uncomfortable discussing the topic with their healthcare provider. This article reviews rectal anatomy and the signs and symptoms of several common anorectal conditions and how to manage them.

[Chronic anal fissure: etiopathogenesis, diagnosis, treatment]. / Khronicheskaia anal'naia treshchina: étiopatogenez, diagnostika, lechenie.

Etiology, epidemiology and pathophysiology of anal fissure are examined in the article in order to determine the most optimal treatment strategy. The authors concluded that the most effective treatment is combined approach using both minimally invasive surgery and various medicines for anal spasm reduction.

The Evaluation and Office Management of Hemorrhoids for the Gastroenterologist.

PURPOSE OF REVIEW: Hemorrhoid disease is extremely common, and seldom requires surgical intervention. The vast majority of patients can be cared for in the office setting and by the gastroenterologist. This piece aims to summarize the epidemiology and pathophysiology of hemorrhoid disease, along with the proper evaluation and office-based treatment of these patients. RECENT FINDINGS: Most GI fellowship training programs spend little time on these topics, and the recommendation has been made to include anorectal care in the GI's "core curriculum." The use of the anoscope and a proper anorectal examination are keys to evaluating these patients, and the techniques available to treat these patients are described. Often overlooked in these patients are other anorectal issues that occur alongside hemorrhoidal issues very commonly-the most common being anal fissure. Comprehensive management of all of these issues will allow all but the most severely affected patients to avoid the expense and morbidity of surgical intervention. The anatomy, etiology, pathophysiology, diagnosis, and non-surgical treatment of hemorrhoid disease are presented with the gastroenterologist in mind.

[Proctology for internists]. / Proktologie für Internisten.

In proctology patients can often be helped with very little effort. With knowledge of the most common disease symptoms the treating physician can in many cases correctly recognize the cause of the complaints and initiate the appropriate therapy or arrange referral to a proctological institution. This article aims to briefly and succinctly present the most common diseases in proctology (e.g. mariscae, hemorrhoids, anal fissures, perianal venous thrombosis, abscesses and fistulas, condyloma acuminatum and anal carcinoma) and to provide the treating internist, even outside of gastroenterology, assistance with the management of proctological symptoms.
