RESUMEN

Introducción: Las infecciones transmisibles sexualmente (ITS) son motivo de consulta frecuente, encontrándose Chlamydia trachomatis (CT) entre las prevalentes. Este germen provoca proctitis de diversa gravedad según el biovar involucrado. Los casos más floridos suelen ser ocasionados por el biovar LGV, responsable de la entidad linfogranuloma venéreo. Se desconocen la prevalencia de CT como causa de proctitis en Argentina y los biovares implicados. Con el objetivo de estudiar estas variables, se diseñó un protocolo para detectar y genotipificar CT en pacientes con proctitis infecciosa. Pacientes y métodos: Se incluyeron pacientes mayores de 18 años con cuadro de proctitis infecciosa atendidos en un centro público y otro privado. Se excluyeron pacientes con enfermedad inflamatoria intestinal y radioterapia pelviana. El estudio fue aprobado por un Comité de Ética y los pacientes firmaron un consentimiento informado. En las muestras de hisopado anal se realizó detección y tipificación molecular de CT. Resultados: Entre 31de agosto de 2017 y 31 de mayo de 2018, se incluyeron 56 pacientes (1 mujer, 53 hombres, 2 mujeres trans), 79% HIV+. En 29 casos (52%) se detectó CT. Todos eran hombres que tienen sexo con hombres (HSH) y refirieron practicar sexo anal u oral receptivo no protegido. La mediana de edad de este subgrupo fue de 31 años; 83% HIV+ en tratamiento antirretroviral y mediana de CD4 637 cel/mm3. La coinfección con otras ITS fue del 41% (siendo las más frecuentes HPV, gonococia y sífilis). Los motivos de consulta más frecuentes fueron proctorragia, pujo y tenesmo, proctalgia y secreción. Las manifestaciones clínicas fueron variadas: proctitis, úlcera perianal, tumor endoanal/rectal y absceso/fístula. El 86% de las proctitis correspondió al biovar LGV, siendo 62% moderadas a graves. La mediana de tiempo de evolución hasta el diagnóstico fue 21 días. Los casos más prolongados correspondieron a cuadros clínicos y endoscópicos más graves. La duración del tratamiento se adecuó al biovar involucrado. Todos los pacientes respondieron favorablemente; sin embargo, las dos fístulas perianales requirieron resolución quirúrgica. Conclusiones: Proctitis, úlceras y fístulas son manifestaciones inespecíficas; el hallazgo clínico y endoscópico per se no son suficientes para definir la etiología; sólo una anamnesis minuciosa permite presumir una ITS como agente causal. La tipificación logra definir el biovar, dato fundamental para adecuar el tratamiento, cortar la cadena de transmisión y contar con datos epidemiológicos a nivel local. Como resultado de esta investigación, el Ministerio de Salud de Nación proyectó la emisión de una alerta sobre la presencia de LGV en nuestro medio. Tipo de estudio: Observacional, transversal, analítico, multicéntrico.

Introduction: Sexually transmitted infections (STI) are a frequent reason for consultation, being Chlamydia trachomatis (CT) among the most prevalent ones. It causes proctitis of varying severity depending on the biovar involved. The most severe cases are usually caused by the LGV biovar, responsible for the entity called lymphogranuloma venereum. The prevalence of CT as a cause of proctitis in Argentina and the biovars involved are unknown. In order to study these variables, a protocol was designed to detect and genotype CT in patients with infectious proctitis. Patients and methods: Patients over 18 years old with infectious proctitis were attended in a public and private center. Patients with inflammatory bowel disease and pelvic radiation therapy were excluded. The study was approved by an Ethics Committee and the patients signed an informed consent. The detection and molecular typing of CT was performed in anal swab samples. Results: Between 31-08-2017 and 31-05-2018, 56 patients were included (1 woman, 53 men, 2 trans women), 79% HIV +. In 29 cases (52%) CT was detected. All were MSM and reported to practice unprotected receptive oral or anal sex. The median age of this subgroup was 31 years; 83% HIV + on antiretroviral treatment and median CD4 637 cel / mm3. The coinfection with other STIs was present 41% (the most frequent were HPV, gonococcal and syphilis). The most frequent symptoms were bleeding, tenesmus, proctalgia and secretion. The clinical manifestations were varied: proctitis, perianal ulcer, endoanal / rectal tumor and abscess / anal fistula. 86% of the proctitis corresponded to the LGV biovar, being 62% moderate to severe. The median time of evolution until the diagnosis was 21 days. The most prolonged cases corresponded to more severe clinical and endoscopic symptoms. The duration of the treatment was adapted to the biovar involved. All patients responded favorably; however, the two perianal fistulas required surgical resolution. Conclusions: Proctitis, ulcers and fistulas are nonspecific manifestations; the clinical and endoscopic findings per se are not sufficient to define the etiology; only a meticulous anamnesis allows us to presume an STI as a causative agent. The typification allows to define the biovar, a fundamental data to adapt the treatment, stop chain of transmission and provides local epidemiological data. As a result of this investigation, the Ministry of Health of the Argentina issued an alert about the presence of LGV in our country. Type of study: Observational, cross-sectional, analytical, multicenter study.

RESUMEN

Sacral neuromodulation involves electrical stimulation of af­ferent nerve roots to restore the balance between inhibitory and excitatory reflexes who improve the functional activity of the pelvic floor. With benefits in patients with fecal inconti­nence, constipation and chronic anorectal pain. Objective. The aim of this study is present the results obtained with sacral neuromodulation for the treatment of patients with fecal incontinence, severe and intractable chronic constipa­tion and chronic anorectal pain. Patients and methods. 33 patients had indication for transitory electrical sacral stimu­lation, 25 patients performed transitory electrical stimula­tion for fecal incontinence, 5 with refractary constipation and 3 with chronic anorectal pain. In cases of fecal inconti­nence, the patients performed previous anorectal manometry and ultrasonography examination of anal sphincters. When the constipation is the indication, we performed stimulation in patients with severe and refractary constipation like step before total colectomy. In cases of chronic anorectal pain, the electrical transitory test was performed according to our treatment algorithm for management of functional anorectal pain. In all cases, if the patients had satisfactory results after 2 weeks period the definitive implant was placed. Results. Mean follow-up was 69 months (range 6-130). Definitve implant was placed for treatment of fecal incontinence in 23 patients with a decrease in fecal incontinence scores in 98%, with an average success rate of 66% (range: 45-92). In cases of constipation, 3 definitive implants were placed, the mean follow-up was 77 months (range: 51-96) with a success rate between 50%-80% as measured by bowel frequency. We performed definitive electrical stimulation in 3 patients wit chronic and intractable anorectal pain. Response rates as measured by visual analog scale were between 40%-70%. Conclusions. Sacral neuromodulation is an area in constant growth, with more indications. The success depends on the correct indication and the patients need to be treated with other therapeutic options before sacral neuromodulation.

RESUMEN

Objetivo: Evaluar el grado de concordancia entre la manometría anorrectal y la ecografía dinámica del piso pelviano (ecodefecografía) mediante la medición del índice kappa, en la detección de la contracción paradojal del haz puborrectal en pacientes que presentan dificultad evacuatoria (DE) ocasionada por pujo disinergico. Material y Método: Se efectuaron manometría anorrectal y ecodefecografía, en 89 pacientes (9 hombres y 80 mujeres) en un centro ambulatorio de coloproctología, a pacientes que presentaban síntomas de obstrucción defecatoria en el período comprendido entre mayo 2011 y mayo 2014. Se reportó la presencia de contracción paradojal del haz puborrectal durante el pujo en las manometrías. En la ecodefecografía se analizó el movimiento del músculo puborrectal, comparando el ángulo anorrectal. durante el reposo y pujo. En caso de constatarse una disminución del mismo durante el esfuerzo evacuatorio se interpreto como contracción paradojal del haz puborrectal. Resultados:. Se obtuvo un índice kappa de 0.87 (IC 95% 0,73-0,97), dando un muy buen grado de acuerdo entre los resultados de ambos estudios, con resultados estadísticamente significativos (p=0,05). Conclusión: La ecodefecografía es una herramienta útil que puede confirmar casos de disinergia demostrada por manometría, pero si bien ambos métodos presentan muy buen grado de acuerdo entre sí, ningún estudio puede reemplazar al otro ya que ambos métodos tienen sus resultados falsos positivos.

Objective: To assess the degree of agreement between anorectal manometry and dynamic pelvic floor ultrasound (echodefecography) by calculating kappa index in patients with symptoms of obstructed defecation. Material and Methods: Anorectal manometry and echodefecography were performed in patients with obstructed defecation symtpoms between May 2011 and May 2014. When the anorectal manometry was performed, the pressures during attempted defecation were recorded. Dyssinergic pattern was defined if a rise in pressures was noted. When the echodefecography was performed, the angle between the internal edges of the puborectalis with a vertical line according to the anal canal axis was calcultated at rest and during straining. Results: Anorectal manometry and echodefecography was performed in 89 patients with defecatory disturbances symptoms. Male:female 9male, the mean age of patients was 57 years old (range 25-78). The assessment of the degree of agreement or concordance between dynamic ultrasound and anorectal manometry yielded a kappa index of 0.87 (very good agreement) with statistically significant results (p=0.05). Conclusion: Ultrasonography may be used to assess patients with obstructed defecation, as it is able to detect the same anorrectal dysfuntions found by another pelvic floor studies. It is a minimally invasive, well tolerated method, and avoids exposure to radiation. Although both methods shows very good agreement with each other, they cannot replace them since both methods have false positive results.

RESUMEN

The aim of this report is to describe a novel technical approach to total anorectal reconstruction and show surgical results and functional outcome. The technique is an innovative surgery to restore gastrointestinal perineal continuity after coloproctectomy in patients with familial adenomatous polyposis. We made the internal anal sphincter replacement with demucosated small bowel plication, the external anal sphincter replacement with an artificial bowel sphincter (ABS) and the restitution of intestinal transit with and ileal "S" pouch. After 12 months follow-up the control of gas is irregular, normal continence to solid stool was achieved with only occasional minimal soiling after defecation. The Jorge-Wexner incontinence score is 6 (moderate incontinence). The fecal incontinence quality of life (FIQL) comparing stoma vs. non-stomas, shows a relevant clinical difference, with improvement in all scales. This study has limitations because it is preliminary, observational and with no control group. We conclude that this recent surgical technique requires expertise in pelvic floor surgery and management of fecal incontinence. The surgeon should be able not only to introduce an artificial anal sphincter, but also to make the plication of intestinal muscle layer to create a zone of high pressure in anal canal and the ileal pouch.

RESUMEN

INTRODUCTION: Fecal incontinence is a complex disease that affects the quality of life of patients suffering from it. Anorectal manometry and endoanal ultrasound 360 grades are included among the studies used. There are no clear agreement about the relevance and usefulness of this studies and their role as apart of diagnostic procedures. OBJECTIVE: To describe the relationship between the clinical severity score in patients with fecal incontinence and the findings of anorectal manometry and endoanal ultrasound. Another objective of this study is to describe the degree of agreement of both methods of study. MATERIAL AND METHODS: The study population includes 74 patients who underwent endoanal ultrasonography and anorectal manometry for fecal incontinence. The presence or absence of ultrasound injury, the pressures obtained by anorectal manometry and its relationship with clinical severity of patients were described. An analysis of the degree of agreement between both methods was performed. RESULTS: The mean age of patients was 53 years old (range 19-84 years). Pressures of anorectal manometry were reduced in 59 patients (79.7%) and normal in 15 (20.3%). The assessment of the degree of agreement or concordance between ultrasound and anorectal manometry yielded a kappa coefficient of 0.25 (acceptable) (P = 0.0001). CONCLUSION: There is a level of acceptable agreement between endoanal ultrasound findings and anorectal manometry when patients with fecal incontinence are evaluated.

RESUMEN

Introducción: El prurito anal es un síntoma de difícil tratamiento en ausencia de factores predisponentes. Cuando no se logra identificar una causa evidente es habitualmente llamado "prurito anal esencial, primario o idiopático" y en los casos de adjudicarse el síntoma a otra patología se lo refiere como prurito anal secundario. El prurito anal esencial es una patología que representa un desafío para el médico tratante debido al poco consenso sobre el tratamiento de la misma. Objetivo: Realizar una revisión bibliográfica sobre prurito anal primario o idiopático. Presentar un algoritmo de diagnóstico y de tratamiento de pacientes que consultan por esta patología. Efectuar una evaluación inicial de los resultados obtenidos a corto plazo. Lugar de aplicación: Centro Privado de Cirugía y Coloproctología de la Ciudad de Buenos Aires. Diseño: Estudio retrospectivo, descriptivo, observacional y longitudinal. Pacientes y métodos: Se presentan 24 pacientes con diagnóstico de prurito anal esencial que fueron sometidos a tratamiento escalonado del mismo. Resultados: Se obtuvo respuesta favorable completa (ausencia del síntoma prurito por un período mayor a 15 días y con ausencia de lesiones por rascado) en 22 de los 24 pacientes (91,66%), en 2 pacientes (8,33%) se obtuvo respuesta casi completa (mejoría que se traduce en prurito leve sin lesiones cutáneas). No hubo recurrencias ni empeoramiento de los síntomas en ningún paciente. Conclusiones: La mayoría de los casos de prurito anal se deben a una causa coloproctológica o dermatológica, siendo menos frecuentes los casos en los que no se observa una causa responsable. Esta situación tiene relativa frecuencia y representa un desafío tanto para el médico tratante como para el paciente.(AU)

Introduction: Pruritus ani is a symptom of difficult treatment in the absence of predisposing factors. When not able to identify an obvious cause is usually called "essential, primary or idiopathic pruritus ani" and in case of winning the symptom to another condition is referred secondary anal itching. The idiopathic anal pruritus is a condition that poses a challenge to the treating physician due to little consensus on the treatment of it. Objetive: To review the literature on primary or idiopathic pruritus ani. To present an algorithm for diagnosis and treatment of patients who consult for this condition. Make an initial assessment of the results obtained in the short term follow-up. Application site: Private Center of Surgery and Coloproctology of the city of Buenos Aires. Design: Retrospective, descriptive, observational and longitudinal study. Patients and Methods: We present 24 patients with idiopathic anal pruritus underwent treatment in stages. Results: Favorable response was obtainded (absence of pruritlls for a period exceeding 15 days and with no scratching injuries) in 22 of 24 patients (91,66%), in 2 patients (8,33%) was obtained almost response almost complete (resulting in improvement mild itching without skin lesions). There was no recurrence or worsening of symptoms in any patient. Conclusions: Most cases of anal pruritus due to one cause dermatological or proctology, being less frequent cases in which there is observed a cause responsible. This situation is relatively common and poses a challengue for both physician and patient.(AU)
