RESUMO

La histiocitosis de células de Langerhans es una expresión de células dendríticas mieloides, asociada a un componente inflamatorio significativo y compromiso sistémico variado. La edad más frecuente de presentación es entre 1 y 4 años, y predomina en el sexo masculino. Se comunica el caso de un niño de 5 años de edad cuya forma de presentación fue una lesión granulomatosa con fístula perianal, afectación pulmonar y de oído externo. El abordaje interdisciplinario permitió llegar al diagnóstico, realizar las intervenciones necesarias e iniciar el tratamiento adecuado.


Langerhans cell histiocytosis is an expression of myeloid dendritic cells, associated with a significant inflammatory component and varied systemic involvement. The most common age at presentation is between 1 and 4 years, and it prevails among male subjects. Here we describe the case of a 5-year-old boy who presented with a granulomatous lesion with perianal fistula and lung and external ear involvement. An interdisciplinary approach helped to make a diagnosis, provide the necessary interventions, and start an adequate treatment.

RESUMO

La infección por Neisseria gonorrhoeae (NG) es considerada de alta prioridad en salud pública, por su capacidad para desarrollar resistencia a la mayoría de los antibióticos empleados para tratarla. La presentación anorrectal suele ser asintomática y frecuente en hombres que tienen sexo con hombres (HSH). En Argentina, se recomienda terapia antibiótica dual (ceftriaxona+azitromicina/doxiciclina) como primera línea empírica. Este estudio observacional y retrospectivo se realizó para evaluar el porcentaje de positividad de NG anorrectal, el perfil de sensibilidad a penicilina, tetraciclina, ciprofloxacina, ceftriaxona, cefixima y azitromicina, así como los aspectos clínicos-epidemiológicos de los pacientes atendidos entre 20/10/2015 y 20/03/2020 en consultorios coloproctológicos de un hospital público. Se detectaron 55/436 hisopados rectales positivos para NG (13%). El 95% era HSH y 71%, VIH+. En 18/55 NG fue la única infección. Las co-infecciones más frecuentes: HPV (38%) y C. trachomatis (35%). La sensibilidad a cefalosporinas de espectro extendido (CEE) y a azitromicina fueron 100% y 98%, respectivamente. Se observó la emergencia local de los primeros cinco aislamientos de NG anorrectal con sensibilidad reducida (SR) a CEE, el primer aislamiento con categoría no-sensible a azitromicina y otro con SR a azitromicina concomitantemente con SR a CEE. Aunque el uso de terapia empírica dual sigue siendo adecuado para nuestra institución, se observó la emergencia de aislamientos con SR y NS a las drogas de primera línea, evidenciando la importancia de la vigilancia epidemiológica a nivel local para definir los tratamientos empíricos.


Neisseria gonorrhoeae (NG) infection is considered a high public health priority because of its ability to develop resistance to most of the antibiotics used to treat it.The anorectal presentation is generally asymptomatic and frequent in men who have sex with men (MSM). In Argentina, dual therapy (ceftriaxone+azithromycin/doxycycline) is recommended as first line empiric therapy.This observational and retrospective study was conducted to evaluate the percentage of anorectal NG positivity, the susceptibility profile to penicillin, tetracycline, ciprofloxacin, ceftriaxone, cefixime and azithromycin, as well as the clinical-epidemiological aspects of patients attended between 20/10/2015 and 20/03/2020 in coloproctology of a public hospital.We detected 55/436 positive rectal swabs for NG (13%). 95% were MSM and 71% were PLHIV. In 18/55 NG was the only infection. The most frequent co-infections: HPV (38%) and C. trachomatis (35%).Susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin was 100% and 98%, respectively. Local emergence of the first five anorectal NG isolates with decreased susceptibility (DS) to ESCs, the first isolate with nonsusceptible category to azithromycin and another with DS to azithromycin concomitantly with DS to ESCs were observed.Although the use of dual empirical therapy continues to be adequate for our institution, the emergence of isolates with DS and NS to first-line drugs was observed, evidencing the importance of epidemiological surveillance at the local level to define empirical treatments

RESUMO

Introducción: El traumatismo anorrectal es una causa poco frecuente de consulta al servicio de emergencias, con una incidencia del 1 al 3%. A menudo está asociado a lesiones potencialmente mortales, por esta razón, es fundamental conocer los principios de diagnóstico y tratamiento, así como los protocolos de atención inicial de los pacientes politraumatizados. Método: Reportamos el caso de un paciente masculino de 47 años con trauma anorrectal contuso con compromiso del esfínter anal interno y externo, tratado con reparación primaria del complejo esfinteriano con técnica de overlapping, rafia de la mucosa, submucosa y muscular del recto. A los 12 meses presenta buena evolución sin incontinencia anal. Conclusión: El tratamiento del trauma rectal, basado en el dogma de las 4 D (desbridamiento, derivación fecal, drenaje presacro, lavado distal) fue exitoso. La técnica de overlapping para la lesión esfinteriana fue simple y efectiva para la reconstrucción anatómica y funcional. (AU)


Introduction: Anorectal trauma is a rare cause of consultation to the Emergency Department, with an incidence of 1 to 3%. It is often associated with life-threatening injuries, so it is essential to know the principles of diagnosis and treatment, as well as the initial care protocols for the polytrau-matized patient. Methods: We present the case of a 47-year-old man with a blunt anorectal trauma involving the internal and external anal sphincter, treated with primary overlapping repair of the sphincter complex and suturing of the rectal wall. At 12 months the patient presents good outcome, without anal incontinence. Conclusion: The treatment of rectal trauma, based on the 4 D ́s dogma (debridement, fecal diversion, presacral drainage, distal rectal washout lavage) was successful. Repair of the overlapping sphincter injury was simple and effective for anatomical and functional reconstruction. (AU)

RESUMO

Antecedentes: La sífilis es una infección sexualmente transmisible sistémica crónica que afecta a docenas de millones de personas al año. A nivel anorrectal, su manifestación polimórfica obliga al diagnóstico diferencial con enfermedades anorrectales benignas y malignas. Objetivo: Describir las diferentes presentaciones de la sífilis anorrectal a propósito de 5 casos clínicos. Método: Estudio observacional, retrospectivo, descriptivo. Resultados: La mayoría de los pacientes fueron VIH positivos en edad sexual activa. Las manifestaciones registradas, al igual que las reportadas en la bibliografía fueron las fisuras, úlceras perianales y pseudotumores. Conclusiones: La sífilis es considerada "la gran simuladora". En la localización anorrectal se requiere una alta sospecha diagnóstica para diferenciarla de presentaciones similares de otras enfermedades anales benignas, la enfermedad inflamatoria intestinal y el cáncer anorrectal, con el fin de evitar el consiguiente riesgo de sobretratamiento. (AU)


Background: Syphilis is a chronic systemic sexually transmitted infection that affects tens of millions of people annually. At the anorectal level, its polymorphic manifestation requires differential diagnosis with benign and malignant anorectal diseases. Objective: To review the presentation of anorectal syphilis from 5 clinical cases. Methods: Observational, retrospective, descriptive study. Results: Most of the patients were HIV positive in sexually active age. The manifestations recorded and reported in the literature were fissures, perianal ulcers, and pseudotumors. Conclusions: Syphilis is considered "the great pretender". In anorectal syphilis, a high diagnostic suspicion is needed to differentiate it from similar presentations due to other anal conditions, inflammatory bowel disease, and anorectal cancer, to avoid the consequent risk of overtreatment. (AU)

RESUMO

Resumo:Introdução:O câncer anal é uma patologia considerada rara, apesar de crescente na população. A citologia anal tem sido uma aposta para diagnosticar as alterações pré-neoplásicas, evitando a evolução ao câncer. Objetivos:I) Abordar aspectos de satisfatoriedade da amostra celular e revisar os critérios citomorfológicos dos achados benignos e malignos nos esfregaços de citologia anal. II) Tornar este artigo um instrumento de suporte aos profissionais de saúde que atuam no setor de Citopatologia vinculados ao Sistema Único de Saúde (SUS) ou à iniciativa privada. Métodos:Revisão narrativa, com busca nas bases PubMed, Science Direct e SciELO, de fevereiro a abril/2023. Desenvolvimento:A análise da literatura aponta para a aplicação da citologia anal para diagnóstico das alterações induzidas pelo Papilomavírus Humano (HPV) no canal anal. O rastreamento se baseia na semelhança ao controle do câncer de colo uterino e à história natural da doença, reconhecendo que as lesões precursoras evoluem ao câncer invasivo. Essa janela entre a lesão e o câncer abre espaço para detecção precoce. Oportunamente, a técnica pode diagnosticar agentes responsáveis por outras Infecções Sexualmente Transmissíveis (IST). Conclusão: Qualificar os laudos de diagnóstico citopatológico pode apoiar o cuidado desde a atenção primária. O intuito deste trabalho foi contribuir com o processo de aprendizagem dos profissionais da saúde e apoiar a saúde pública nas estratégias de garantia de cuidado às pessoas.

RESUMO

OBJECTIVE To investigate the effect and mechanism of Panax notoginseng saponins (PNS) on wound healing after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF)/ vascular endothelial growth factor receptor-2 (VEGFR2) signaling pathway. METHODS SD rats were selected to establish a postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model group, PNS low-dose and high-dose groups (15, 30 mg/cm2), high-dose of PNS+2-methoxyestradiol (2ME2) group (PNS 30 mg/cm2+HIF-1α inhibitor 2ME2 4 mg/kg), with 10 rats in each group. Another 10 normal rats were selected for back hair removal treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or (and) intraperitoneally, once a day, for 3 weeks. After the last administration, the wound healing rate (excluding the control group), microvascular density (MVD), the expression of collagen Ⅰ and fibronectin (FN) in the wound tissue were detected in each group; the levels of angiogenic factors [VEGF, E-mail:842710813@qq.com angiopoietin-Ⅰ (Ang-Ⅰ), Ang-Ⅱ] in serum, the levels of inflammatory factors [interleukin-6 (IL-6) and IL-2] in serum binggui7183@163.com and wound tissue as well as the expressions of the related proteins of HIF-1α/VEGF/VEGFR2 signaling pathway in the wound tissue of rats were also detected in each group. RESULTS The MVD, the expression of collagen Ⅰ and FN in the wound tissue, and the levels of IL-6 and IL-2 in serum and wound tissue of rats increased significantly in the model group, compared to the control group (P<0.05), while the serum levels of VEGF, Ang- Ⅰ and Ang-Ⅱ decreased significantly (P<0.05). The wound healing rate, the MVD in wound tissue, the serum levels of VEGF, Ang-Ⅰ and Ang-Ⅱ, the expressions of collagen Ⅰ and FN in the wound tissue, and protein expressions of HIF-1α, VEGF and VEGFR2 in the PNS low-dose and high-dose groups increased significantly, compared to the model group (P<0.05), while the levels of IL-6 and IL-2 in serum and wound tissue decreased significantly (P<0.05); the high-dose PNS had a stronger effect (P< 0.05). 2ME2 could weaken the effect of PNS on above indicators of rats after anal fistula surgery (P<0.05). CONCLUSIONS PNS can promote the production of angiogenic factors and inhibit the production of pro-inflammatory factors, thereby promoting wound healing in rats after anal fistula surgery. The above effects are related to the activation of HIF-1α/VEGF/VEGFR2 signaling pathway.

RESUMO

Abstract Background: Ultra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). Methods: A two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. Results: Fifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). Conclusion: SA and PB are similarly effective in pain control during the first 48 h after hemorrhoidec-tomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Objetivo: Evaluar la efectividad del tratamiento con plasma rico en plaquetas y leucocitos en pacientes con fisura anal secundaria que asistieron a la consulta de Coloproctología del Hospital Docente Provincial Oncológico María Curie de Camagüey en el período de enero de 2020 a enero de 2023. Métodos: Se realizó un estudio cuasiexperimental. El universo lo conformaron todos los pacientes que acudieron a consulta en ese período. La muestra no probabilística intencionada la conformaron 130 pacientes adultos con diagnóstico de fisura anal secundaria que recibieron tratamiento con plasma rico en plaquetas y leucocitos. Resultados: El tiempo de cicatrización de la fisura anal permitió corroborar la efectividad del tratamiento; además, la mayoría de los pacientes evolucionaron de forma favorable. El dolor fue la complicación más visible pues presentó significación estadística al establecer la relación entre las variables. Se demostró que el tratamiento con plasma rico en plaqueta y leucocitos en pacientes con fisura anal secundaria es efectivo y seguro en la evaluación final del tratamiento. Conclusiones: Lo expuesto permite considerar que los pacientes tratados obtuvieron buenos resultados al hacer uso del plasma rico en plaquetas y leucocitos. Por consiguiente, tiene un resultado positivo en no mostrar complicaciones y una alta posibilidad de que el paciente tratado evolucione en mejor condición(AU)


Introduction: Platelet-rich plasma is a blood-derived product, rich in peptides and intercellular signaling proteins, as well as cytokines capable of intervening in each of the stages of regeneration of various tissues. Objective: To assess the effectiveness of treatment with platelet- and leucocyte-rich plasma in patients with secondary anal fissure who attended the coloproctology office at Hospital Docente Provincial Oncológico María Curie of Camagüey from January 2020 to January 2023. Methods: A quasiexperimental study was carried out, whose universe consisted of all the patients who came for consultation during that period. The nonprobabilistic purposive sample consisted of 130 adult patients with a diagnosis of secondary anal fissure who received treatment with platelet- and leucocyte-rich plasma. Results: The healing time of the anal fissure allowed corroborating the effectiveness of the treatment; in addition, most of the patients evolved favorably. Pain was the most visible complication since it presented statistical significance when the relationship between the variables were established. Treatment with platelet- and leucocyte-rich plasma in patients with secondary anal fissure proved effective and safe in the final assessment of the treatment. Conclusions: The above allows considering that the treated patients obtained good outcomes when making use of platelet- and leucocyte-rich plasma. Therefore, it has a positive outcome, not showing complications and a high possibility for the treated patient to evolve in a better condition(AU)

RESUMO

Introduction: Anal squamous cell carcinoma is rare, but its incidence and mortality have been increasing globally; 90% of cases are related to human papillomavirus (HPV) infection(1,2). Patients with inflammatory bowel disease (IBD) have a higher risk of infection with this virus; an incidence of 5.5 per 100,000 patients has been identified in the IBD group compared to 1.8 in the non-IBD group(3). Materials and methods: A descriptive case series study was conducted with 21 patients with IBD and no perianal symptoms between January and July 2022 at the Institute of Coloproctology in Medellín. They underwent anal cytology, HPV genotyping, and high-resolution anoscopy after explanation and acceptance of the procedure. If lesions were found, ablative treatment was performed. Results: 23% of this cohort had low-grade squamous lesions, while 14.2% had high-grade lesions with dysplasia changes during anoscopy. Besides, 90.4% had positive HPV genotyping, of which 76.1% were high-grade. Conclusions: Our study suggests that this series of patients with IBD behaves as a high-risk group for developing premalignant lesions in association with HPV. High-resolution anoscopy is a cost-effective, painless, and affordable method that, in expert hands, may impact the diagnosis and management of premalignant lesions and decrease the incidence of anal cancer in patients with IBD.


Introducción: El carcinoma anal de células escamosas es raro, pero su incidencia y mortalidad han ido en aumento globalmente. El 90% de los casos están relacionados con la infección por el virus del papiloma humano (VPH)1,2 y los pacientes con enfermedad inflamatoria intestinal (EII) tienen un mayor riesgo de infección por este virus; se ha identificado una incidencia de 5,5 por 100.000 pacientes en el grupo de EII frente a 1,8 en el grupo sin EII3. Metodología: Se realizó un estudio descriptivo de serie de casos en el que se incluyó a 21 pacientes con EII, sin síntomas perianales, entre enero y julio de 2022 en el Instituto de Coloproctología de Medellín, a quienes se les realizó citología anal, genotipificación del VPH y anoscopia de alta resolución, previa explicación y aceptación del procedimiento. Si se encontraban lesiones, se realizaba tratamiento ablativo. Resultados: El 23% de esta cohorte tenía lesiones escamosas de bajo grado, mientras que el 14,2% presentaba lesiones de alto grado con cambios de displasia al momento de la anoscopia. El 90,4% tenían genotipificación positiva para VPH, de los cuales el 76,1% eran de alto grado. Conclusiones: Nuestro estudio sugiere que esta serie de pacientes con EII se comporta como un grupo de alto riesgo para desarrollar lesiones premalignas en asociación con el VPH. La anoscopia de alta resolución es un método rentable, indoloro y asequible que, en manos expertas, puede impactar el diagnóstico y manejo de lesiones premalignas y disminuir la incidencia de cáncer anal en pacientes con EII.

RESUMO

Introducción: Los carcinomas neuroendocrinos (NEC) de canal anal son neoplasias extremadamente raras, representando del 1 a 1,6% de la totalidad de los tumores neuroendocrinos (NET). Suelen ser poco diferenciados, muy agresivos y con alta tendencia a metastatizar. Caso clínico: Mujer de 52 años diagnosticada de fisura anal. Durante la esfinterotomía lateral interna (ELI) se evidencia un pólipo milimétrico aparentemente hiperplásico. Biopsia: NEC de alto grado. En el estudio de extensión se observa engrosamiento de la mucosa del canal anal que invade el esfínter interno, sin enfermedad a distancia. Se realiza amputación abdominoperineal laparoscópica donde se objetiva infiltración del tabique rectovaginal, por lo que se realiza resección y vaginoplastia. AP: NEC con estadio PT4B N2A, por lo que se indica quimioterapia adyuvante. Discusión: La presentación clínica de los NEC de canal anal es inespecífica, diferenciándose de otros tumores colorrectales en que hasta el 67% de los pacientes presentan metástasis al diagnóstico, siendo la supervivencia media de 11 meses. Si diagnosticamos un NEC localizado de forma incidental, es fundamental la celeridad en su tratamiento, dada su agresividad.


Introduction: Neuroendocrine carcinomas (NEC) of the anal canal are extremely rare neoplasms, representing 1 to 1.6% of all neuroendocrine tumors (NET). They are usually poorly differentiated, very aggressive and with a high tendency to metastasize. Clinical case: A 52-year-old woman diagnosed with anal fissure. During the LIS, an apparently hyperplastic millimetric polyp is evidenced. Biopsy: high-grade NEC. The imaging study shows thickening of the mucosa of the anal canal that invades the internal sphincter, without metastases. We performed a laparoscopic abdominoperineal amputation, and noticed an infiltration of the rectovaginal septum, so resection and vaginoplasty was performed. Pathology: NEC with stage PT4B N2A, for which adjuvant chemotherapy is indicated. Discussion: The clinical presentation of NEC of the anal canal is nonspecific, differing from other colorectal tumors in that up to 67% of patients have metastases at diagnosis, with a median survival of 11 months. When an incidentally localized NEC is diagnosed, prompt treatment is essential, given its aggressiveness.

RESUMO

Introducción: Las enfermedades benignas de recto son muy frecuentes en la práctica médica habitual en todos los niveles de atención de salud. Dentro de estos procesos se reconoce que la fisura anal es uno de los más comunes. Objetivo: Caracterizar a los pacientes tratados con plasma rico en plaquetas y leucocitos por fisura anal secundaria en la provincia Camagüey en el período comprendido entre septiembre del 2020 y septiembre del 2022. Métodos: Se realizó un estudio cuasiexperimental, cuyo universo lo conformaron los pacientes con el diagnóstico de fisura anal secundaria que asistieron a la consulta de Coloproctología del Hospital Provincial Docente Oncológico María Curie. Se estableció una muestra no probabilística a criterio de los autores conformada por 132 pacientes adultos, quienes recibieron tratamiento con plasma rico en plaquetas y leucocitos por fisura anal secundaria en la provincia Camagüey. Resultados: Con respecto al sexo y a la edad, se observó una mayor frecuencia del grupo de 40 a 49 años y predominó el sexo femenino. El síntoma de mayor frecuencia fue el dolor, mientras que en la etiología prevaleció la proctitis facticia. En la mayoría de los casos estudiados la fisura anal cicatrizó en menos de 15 días y en cuanto a la evaluación final del tratamiento solo la minoría empeoró. Conclusiones: La caracterización de la muestra en estudio permite afirmar que el tratamiento con plasma rico en plaquetas y leucocitos tiene beneficios para los pacientes con fistulas perianales y su calidad de vida(AU)


Introduction: Benign rectal diseases are very frequent in routine medical practice at all levels of health care. Among these processes, anal fissure is recognized as one of the most common. Objective: To characterize patients treated with platelet-rich plasma and leukocytes for secondary anal fissure in Camagüey Province between September 2020 and September 2022. Methods: A quasiexperimental study was carried out, whose universe was made up of patients with the diagnosis of secondary anal fissure who attended the coloproctology office at Hospital Provincial Docente Oncológico María Curie. A nonprobabilistic sample was established according to the authors' criterions, made up of 132 adult patients who received treatment with platelet-rich plasma and leukocytes for secondary anal fissure in Camagüey Province. Results: Regarding sex and age, a higher frequency was observed in the group 40 to 49 years old and the female sex was predominant. The most frequent symptom was pain, while the prevailing etiology was factitious proctitis. In most of the cases under study, the anal fissure healed in less than 15 days and, regarding the final assessment of the treatment, only the minority worsened. Conclusions: The characterization of the sample under study allows to affirm that treatment with platelet-rich plasma and leukocytes has benefits for patients with perianal fistulas and their quality of life(AU)

RESUMO

Las lesiones obstétricas del esfínter anal pueden ocurrir durante el parto vaginal espontáneamente o secundariamente a la episiotomía. Su riesgo se estima en un 26% y son la causa más frecuente de incontinencia anal en mujeres jóvenes. Las lesiones de grado 4 de Sultan, también llamadas cloaca traumática, implican la ruptura completa del esfínter y la comunicación de la cavidad vaginal con el canal anal. La reparación es siempre quirúrgica, para lo que se han descrito diferentes técnicas, aunque ninguna ha demostrado ser superior. Presentamos el caso de una paciente primípara de 23 años con una cloaca traumática posparto. La reparación quirúrgica se realizó de inmediato con una técnica de overlapping. El postoperatorio fue sin complicaciones y al año presenta continencia anal completa. (AU)


Obstetric anal sphincter injuries can occur spontaneously or as a consequence of an episiotomy during vaginal delivery. Their risk is estimated at 26% and they are the most frequent cause of anal incontinence in young women. Sultan grade 4 injuries, also called traumatic cloaca, involve complete rupture of the sphincter and communication of the vaginal cavity with the anal canal. The repair is always surgical, for which different techniques have been described, although none have proven to be superior. We present the case of a 23-year-old primiparous patient with a postpartum traumatic cloaca. Surgical repair was performed immediately with an overlapping technique. The postoperative period was without complications and one year later she presents complete anal continence. (AU)

RESUMO

La incontinencia anal (IA) tiene una alta prevalencia en la sociedad, aumenta con la edad, presenta elevados costes económicos y tiene un importante impacto negativo en la calidad de vida de los pacientes que la padecen. El tratamiento quirúrgico se reserva para aquellos pacientes que no responden a medidas conservadoras. Clásicamente, las técnicas de reparación muscular han jugado un papel principal en el tratamiento de la IA, sobre todo en aquellos casos en los que había un defecto del complejo esfinteriano, siendo la más extendida la esfinteroplastía solapante y reservando técnicas más complejas como la graciloplastía para casos con lesiones esfinterianas catastróficas. Otras técnicas como la reparación total del suelo pélvico se encuentran en desuso por sus pobres resultados.


Anal Incontinence (AI) is a prevalent disease, increases with aging, has high economic costs and a deep impact in the quality of life of the patients who suffer it. Surgical treatment is proposed in patients with no-response to medical therapy. Muscle repair techniques have been the main approach in AI, specially when there is a sphincteric damage. Overlapping sphincteroplasty is the most common technique and graciloplasty is used when there is a wide damage in sphinteric complex. Some other techniques such as postanal or total pelvic floor repair are not used any more because of their poor results.

RESUMO

Introduction: Treatment of complex fistulas such as inter- or transsphincteric, recurrent, and high fistulae have high rate of recurrence or incontinence. Fistulectomy with primary sphincter reconstruction might represent an effective and safe alternative to reduce rate of recurrence and incontinence. The aim of this study is to assess incontinence and recurrence after fistulectomy with primary sphincter reconstruction for management of complex fistulas. Material and Methods: There were 60 patients with complex fistulae involving the sphincter, with 56 male and 4 female, mean age 40.6 years, operated by fistulectomy and primary sphincter repair over a period of 7 years. Patients were followed up for 6months for any complications, recurrence, and incontinence. Results: The majority of patients (50, 83.3%) had complete wound healing in 2 weeks, while 4 (6.6%) patients had hematoma and superficial wound dehiscence, which were managed conservatively and healed in 4 weeks. There was one recurrence. All patients had good continence postoperatively, except for mild fecal incontinence (FI, score 3), seen in 6 (10%) patients. However, all these patients regained continence within 6 weeks. Conclusions: Primary reconstruction of anal sphincter with fistulectomy is a safe option for complex fistula-in-ano. (AU)

RESUMO

Human papillomavirus (HPV) infection is one of the most common sexually transmitted viral diseases. A descriptive cross-sectional study was conducted with the purpose of clinically and epidemiologically characterizing anal HPV infection in patients who attended the Benign Orificial Pathology Consultation of the Coloproctological Unit at the Dr. "Antonio María Pineda" Central University Hospital, during the period March 2022 -February 2023, by selecting 288 patients whose average age was 47.09 ± 14.61 years, being the 41-50 years old group (29.17%) and the 51-60 years old group (19.44%) the most affected groups by pathologies of the anal region, with a predominance of male (54.17%). The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection. (AU)

RESUMO

La fisura anal es una de las enfermedades más antiguamente descritas, la misma que, ha tenido hasta el momento múltiples tratamientos tanto médicos como quirúrgicos, existiendo controversias en su algoritmo terapéutico. Constituye una de las patologías cuyo diagnóstico y tratamiento corresponde a la Especialidad de Coloproctología, afecta a ambos sexos y a cualquier edad y puede ser aguda o crónica. Proponemos el presente Protocolo para un adecuado manejo de la patología, de manera que sirva de guía en la toma correcta de decisiones basadas en la evidencia y el consenso de quienes integramos la Unidad Técnica de Coloproctología del Hospital de Especialidades Carlos Andrade Marín.


Anal fissure is one of the oldest described diseases, which has so far had multiple medical and surgical treatments, with controversies in its therapeutic algorithm. It is one of the pathologies whose diagnosis and treatment corresponds to the Coloproctology Specialty, it affects both sexes and any age and can be acute or chronic. We propose the present Protocol for an adequate management of the pathology, so that it serves as a guide in the correct decision making based on evidence and consensus of those who integrate the Technical Unit of Coloproctology of the Hospital de Especialidades Carlos Andrade Marín.

RESUMO

RESUMEN La incidencia del cáncer anal ha presentado un incremento en los últimos 10 años, sobre todo en población considerada vulnerable. Las mujeres con antecedentes de infección por Virus del Papiloma Humano (VPH) en el tracto genital, tienen mayor riesgo de este tipo de cáncer. Se ha demostrado que, la infección con genotipos de VPH de alto riesgo (AR), en la región anogenital, desempeña un papel en la etiopatogenia de dicho cáncer. Se desconocen muchos aspectos de la historia natural de las lesiones anales, pero se considera que la zona de transición anal presenta un alto recambio celular, por lo que se ha planteado un mecanismo fisiopatológico de infección por VPH-AR y desarrollo de lesiones invasoras, similar al del cáncer cervical. El objetivo de este trabajo fue mostrar el estado actual sobre la información epidemiológica que vincula el riesgo de desarrollar cáncer anal en mujeres con lesiones precursoras de cáncer cervical asociadas a la infección por VPH. La relevancia de dicha información es proporcionar una base de recomendaciones para la detección oportuna de cáncer anal en mujeres consideradas de AR de padecerlo y, favorecer la realización de estudios prospectivos en la población.


ABSTRACT The incidence of anal cancer has increased in the last 10 years, especially in the population considered to be at risk. Women with a history of infection in the genital tract by Human Papillomavirus (HPV) have higher risk of developing this type of cancer. The presence of high-risk (HR) HPV genotypes in the anogenital region has been shown to play a role in the etiopathogenesis of anal cancer. Many aspects of the natural history of anal lesions are unknown, but the anal transition zone is considered to have a high cell replacement. This is why a pathophysiological mechanism of HR-HPV infection and development of invasive lesions similar to those of cervical cancer has been suggested. The aim of this work was to show the current status of the epidemiological information that links the risk of developing anal cancer in women with cervical cancer precursor lesions associated with HPV infection. The relevance of this information is to provide a basis of recommendations for the timely detection of anal cancer in women considered to be at HR of suffering it, and to encourage more prospective studies in this population.

RESUMO

Introduction: Anal examination and videoanoscopy (VA) are rarely performed during colonoscopies. In recent years, there has been a considerable increase in lesions of sexually transmitted anal and rectal infections, but these conditions are not noticed or reported during routine colonoscopy. Objective: To raise awareness regarding the fortuitous findings of lesions and sexually transmitted infections (STIs) in colonoscopy exams and to demonstrate that anal examination and VA provide important information and should be routinely performed. Methods: We conducted a descriptive retrospective study in 16,132 patients screened by colonoscopy and VA between 2006 and 2018. Among numerous other findings, the presence of anal condylomata and sexually transmitted retitis or perianal dermatitis was observed. The rates of each finding were calculated, and the patients were subdivided by sex and into age groups by blocks of ten years. Results: Among the 16,132 colonoscopies performed, 26 cases of condyloma (0.16%) and 50 cases of proctitis or perianal dermatitis suspicious for STI (0.33%) were found. Conclusion: Performing anal examination and VA systematically in all routine colonoscopies enabled the identification of numerous anal conditions, including several fortuitous cases of STIs. The study proposes that anal examination and VA should be performed in all routine colonoscopies and, in suspected cases, complementary tests for STIs. (AU)

RESUMO

The gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.
