Intrarectal formalin treatment for haemorrhagic radiation-induced proctopathy: efficacy and safety.

AIM: Pelvic radiotherapy is limited by dose-dependent toxicity to surrounding organs. The aim of this prospective study was to evaluate the efficacy and safety of intrarectal formalin treatment for radiotherapy-induced haemorrhagic proctopathy (RHP) at the Royal Marsden Hospital. METHOD: Adult patients were enrolled. Haemoglobin was evaluated before and after formalin treatment. Antiplatelet and/or anticoagulation treatment and administration of transfusion were recorded. The interval between completion of radiotherapy and the first intrarectal 5% formalin treatment was assessed and the dose of radiotherapy was evaluated. Clinical assessment of the frequency and amount of rectal bleeding (rectal bleeding score 1-6) and endoscopic appearance (grade 0-3) were classified. Complications were recorded. RESULTS: Nineteen patients were enrolled, comprising 13 men (68%) and 6 women. The mean age was 75 ± 9 years. The median time between completion of radiotherapy and the first treatment was 20 months [interquartile range (IQR) 15 months] and the median dose of radiotherapy was 68 Gy (IQR 14 Gy). Thirty-two procedures were performed (average 1.7 per patient). In total, 9/19 (47%) patients were receiving anticoagulation and/or antiplatelet medication and 5/19 (26%) received transfusion prior to treatment. The mean value of serum haemoglobin before the first treatment was 110 ± 18 g/L and afterwards it was 123 ± 16 g/L (p = 0.022). The median rectal bleeding score before the first treatment was 6 (IQR 0) and afterwards 2 (IQR 1-4; p < 0.001), while the median endoscopy score on the day of first treatment was 3 (IQR 0) compared with 1 (IQR 1-2) on the day of the last treatment 1 (p < 0.001). One female patient with a persistent rectal ulcer that eventually healed (18 months of healing) subsequently developed rectovaginal fistula (complication rate 1/19, 5%). CONCLUSIONS: Treatment with intrarectal formalin in RHP is effective and safe.

Acute Aortic Dissection Presenting as Rectal Tenesmus.

BACKGROUND Acute aortic dissection (AAD) is a life-threatening medical emergency that requires a high index of clinical suspicion to be diagnosed promptly. The variability in the clinical presentation of AAD has historically made it difficult to identify in the acute setting. There remains significant inter-physician variability in the use of imaging. The median time to diagnosis in the Emergency Department is over 4 h and AAD has a mortality rate of 68% when diagnosis is delayed by over 48 h after onset of symptoms. CASE REPORT We discuss a case of a 69-year-old woman presenting with gastrointestinal symptoms in the Emergency Department who ultimately was found to have AAD. The patient had delayed presentation by 12 h due to misattribution of her rectal tenesmus to irritable bowel syndrome. However, after a thorough history and physical exam, the Emergency Medicine physician appropriately risk-stratified the patient and correctly diagnosed her with a Stanford Type A aortic dissection using a computed tomography study of the chest, abdomen, and pelvis with intravenous contrast. CONCLUSIONS AAD is an uncommon disease often requiring emergency intervention. We summarize the research and scoring systems and discuss the physical exam findings, comorbidities, imaging modalities, and risk stratification tools. Although imperfect, the Aortic Dissection Detection Risk Score with the addition of a D-dimer test is currently the best-validated tool and should be an important part of clinical decision making prior to performing computed tomography imaging.

Pleasurable and problematic receptive anal intercourse and diseases of the colon, rectum and anus.

The ability to experience pleasurable sexual activity is important for human health. Receptive anal intercourse (RAI) is a common, though frequently stigmatized, pleasurable sexual activity. Little is known about how diseases of the colon, rectum, and anus and their treatments affect RAI. Engaging in RAI with gastrointestinal disease can be difficult due to the unpredictability of symptoms and treatment-related toxic effects. Patients might experience sphincter hypertonicity, gastrointestinal symptom-specific anxiety, altered pelvic blood flow from structural disorders, decreased sensation from cancer-directed therapies or body image issues from stoma creation. These can result in problematic RAI - encompassing anodyspareunia (painful RAI), arousal dysfunction, orgasm dysfunction and decreased sexual desire. Therapeutic strategies for problematic RAI in patients living with gastrointestinal diseases and/or treatment-related dysfunction include pelvic floor muscle strengthening and stretching, psychological interventions, and restorative devices. Providing health-care professionals with a framework to discuss pleasurable RAI and diagnose problematic RAI can help improve patient outcomes. Normalizing RAI, affirming pleasure from RAI and acknowledging that the gastrointestinal system is involved in sexual pleasure, sexual function and sexual health will help transform the scientific paradigm of sexual health to one that is more just and equitable.

Caracterización del tratamiento con plasma rico en plaquetas y leucocitos en la fisura anal secundaria / Characterization of the Treatment with Platelet-Rich Plasma and Leukocytes against Secondary Anal Fissure

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)

Conclusions: The nurses' level of knowledge about nursing interventions in outpatient surgery for anorectal diseases was identified as unsatisfactory(AU)

Proctitis infecciosa por Chlamydia Trachomatis / Infectious proctitis by Chlamydia Trachomatis

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.

Tratamiento quirúrgico de la endometriosis pélvica profunda con compromiso colorrectal / Surgical treatment of deep pelvic endometriosis with colorectal involvement

INTRODUCCIÓN: En la endometriosis el compromiso intestinal afecta hasta al 12% de las pacientes, comprometiendo al recto y a la unión rectosigmoidea en el 90% de los casos. OBJETIVO: Describir la experiencia del equipo de Coloproctología y Ginecología de Clínica Alemana de Santiago en el tratamiento quirúrgico de la endometriosis pélvica profunda con compromiso colorrectal. MATERIAL Y MÉTODOS: Estudio retrospectivo a partir de la base de datos de pacientes con endometriosis tratados entre enero del año 2015 y abril de 2018. Los criterios de inclusión fueron pacientes con clínica de endometriosis pélvica profunda, que tuviesen compromiso colorrectal y hayan sido tratados con shaving rectal, resección discoide o resección segmentaria. Se revisaron fichas clínicas electrónicas, protocolos operatorios y biopsias definitivas. RESULTADOS: Se reclutaron 25 pacientes con una mediana de edad de 35 años. El síntoma principal de consulta fue dismenorrea y el síntoma digestivo más frecuente fue disquecia. En 8 pacientes se realizó un shaving rectal, en 7 una sigmoidectomía, en 9 una resección discoide y en 1 paciente una tiflectomía. La complicación posoperatoria reportada fue la hemorragia digestiva baja en 4 pacientes (Clavien-Dindo I y IIIa). Con una mediana de seguimiento de 13 meses, a la fecha 3 pacientes se les ha diagnosticado algún tipo de recidiva. CONCLUSIÓN: Es importante que la cirugía a realizar, garantice una morbilidad y recurrencia baja. Los resultados en nuestro centro son alentadores, lo que nos hace creer que el tratamiento quirúrgico podría ser una buena alternativa en la endometriosis pélvica profunda con compromiso colorrectal.

INTRODUCTION: In endometriosis, intestinal involvement affects up to 12% of patients, compromising the rectum and the rectosigmoid junction in 90% of cases. AIM: Describe the experience of the Coloproctolgy and Gynecology Team of the Clínica Alemana de Santiago in the surgical treatment of deep pelvic endometriosis with colorectal involvement. MATERIAL AND METHODS: Retrospective study based on the database of patients with endometriosis treated between January 2015 and April 2018. The inclusion criteria were patients with deep pelvic endometriosis clinic, who had colorectal involvement and who had been treated with rectal shaving, discoid resection or segmental resection. Electronic clinical records, operative protocols and definitive biopsies were reviewed. RESULTS: Twenty-five patients with a median age of 35 years were recruited. The main symptom of consultation was dysmenorrhoea and the most frequent digestive symptom was dyschezia. In 8 patients a rectal shaving was performed, in 7 a sigmoidectomy, in 9 a discoid resection and in 1 patient a tiflectomy. The only reported post-operative complication was low gastrointestinal bleeding in 4 of the 25 patients (Clavien-Dindo I and IIIa). A median follow-up of 13 months was achieved, to date 3 patients have been diagnosed with some type of recurrence. CONCLUSION: It is important that the surgery to be performed guarantees low morbidity and recurrence. The results in our center are encouraging, which makes us believe that surgical treatment could be a good alternative in deep pelvic endometriosis with colorectal involvement.

Rectal syphilis in a HIV patient from Peru / Sífilis rectal en un paciente con VIH de Perú

We present the case of a 53-year-old male patient, a man who had sex with men. He described the presence of inguinal adenopathy and non-painful ulcer with indurated edges on his penis that heal spontaneously after 3 months. In the same period of time the patient presented: tenesmus, bleeding and rectal pain. In the proctoscopy was observed at the level of the rectum: deep ulcer with regular and indurated edges, ulcerated bed with abundant mucus; The rectal mucosa around the ulcer had multiple circumferential erosions 2-4 mm in diameter. The biopsy showed infiltration of lymphomonocollar cells and granulomas. The HIV ELISA test was positive, CD 4: 275 cel./uL, HIV viral load: 10 300 copies / ml, VDRL: Non-reactive, FTA-Abs: 1/10 (positive). Warthin-Starry staining was used in the rectal ulcer biopsy sample identifying spirochetes. After the administration of benzatinic Penicillin G, the symptoms and lesions in the rectal region were resolved. Likewise, antiretroviral treatment was initiated. Ulcerative and erosive proctitis is common in people living with HIV infection, however, it is rare to identify spirochetes in the biopsy sample.

Presentamos el caso de un paciente varon de 53 años de edad, un hombre que tenía sexo con hombres. El describió la presencia de adenopatía inguinal y úlcera no dolorosa con bordes indurados en su pene que cicatrizó espontáneamente luego de 3 meses. En el mismo periodo de tiempo el paciente presentó: tenesmo, sangrado y dolor rectal. En la proctoscopía se observó a nivel del recto: úlcera profunda con bordes regulares e indurados, lecho ulceroso con abundante moco; la mucosa rectal alrededor de la ulcera tenía múltiples erosiones circunferenciales de 2-4 mm de diámetro. La biopsia mostró infiltrado de células linfomonocleares y granulomas. El examen de ELISA VIH resultó positivo, CD 4: 275 cel./uL, carga viral VIH: 10 300 copias / ml, VDRL: No reactivo, FTA-Abs: 1/10 (Positivo). Se utilizó la tinción de Warthin-Starry en la muestra de biopsia de ulcera rectal identificando espiroquetas. Luego de la administración de Penicilina G benzatinica, se resolvieron los síntomas y lesiones en la región rectal. Así mismo se inició el tratamiento antirretroviral. La proctitis ulcerosa y erosiva es frecuente en personas que viven con infección por VIH, sin embargo, es raro identificar espiroquetas en la muestra de biopsia.

Características clínicas asociadas a colitis eosinofílica en lactantes con rectorragia persistente / Clinical features of Eosinophilic Colitis in infants with persistent rectal bleeding

The most common presentation of cow's milk protein allergy (CMP) in infants is known as eosinophilic colitis (EC). The aim of this study is to evaluate EC characteristics in infants evaluated with colonoscopy due to the presence of rectorrhagia. Patients and Methods: A retrospective case-control study. Left-sided colonoscopy records of infants with persistent rectal bleeding, conducted between January 2006 and March 2011, were reviewed. The cases corresponded to infants with rectal biopsy compatible with EC and controls with negative biopsy. Telephone questionnaires to parents were conducted, evaluating personal and family history. Results: Complete records were obtained in 61 (79%) of the 77 procedures. 33 (54%) of them were males. Examination average age was 6.3 ± 5.9 months. 25 (41%) patients had EC on their histology. Between cases and controls, no significant difference in gestational age, birth weight and gender, only regarding age at the time of rectal bleeding, were observed. There was also no difference in personal history regarding obstructive bronchitis, allergic rhinitis, family history of asthma, allergic rhinitis or other food allergies. Those who received artificial feeding did not presented greater risk of EC. The most common symptoms in the cases did not differ significantly from the controls. Conclusions: The prevalence of EC in the children studied was 40.9%. Our results show that there are groups of patients with persistent rectal bleeding in which there is no personal or family history that helps diagnosing EC. An endoscopic study could be considered in these patients to establish a correct diagnosis of this condition, avoid unnecessary diets and not to delay the detection of other diseases.

En lactantes, la forma de presentación más común de la alergia a la proteína de la leche de vaca (PLV) es la colitis eosinofílica (CE). El objetivo de este trabajo es evaluar características clínicas asociadas a CE en lactantes evaluados con colonoscopía por la presencia de rectorragia. Pacientes y Método: Estudio caso-control, retrospectivo. Se revisaron registros de colonoscopía izquierda de lactantes con rectorragia persistente, realizadas entre Enero 2006 y Marzo 2011. Casos fueron lactantes con rectorragia y biopsia compatible con CE y controles aquellos con biopsia negativa. Se realizó un cuestionario vía telefónica a los padres, evaluándose antecedentes personales y familiares. Resultados: En 61 (79%) de 77 procedimientos se obtuvo registros completos. 33 (54%) eran hombres. Edad promedio del examen fue 6,3 ± 5,9 meses. 25 (41%) pacientes presentaron CE en la histología. Sin diferencia significativa en edad gestacional, peso de nacimiento ni sexo, pero si en edad de presentación de la rectorragia, entre casos y controles. Tampoco hubo diferencia en antecedentes personales de bronquitis obstructivas, rinitis alérgica, ni antecedentes familiares de asma, rinitis alérgica u otras alergias alimentarias. Quienes recibieron lactancia artificial no tuvieron mayor riesgo de CE. Los síntomas más frecuentes en los casos no se diferenciaron significativamente de los controles. Conclusión: La prevalencia de CE en los niños estudiados fue de 40,9%. Nuestros resultados muestran que hay grupos de pacientes con rectorragia persistente en los cuales no existen antecedentes de la historia familiar ni personal que permitan establecer el diagnóstico de CE. Es en estos pacientes en los cuales podría considerarse el estudio endoscópico para establecer un correcto diagnóstico de esta patología, evitar dietas innecesarias y no retrasar la detección de otras enfermedades.

Ulceración rectal como una complicación del uso de sistema de control fecal Fexi-Seal: relato de casos / Ulceração retal como uma complicação do uso do sistema de controle fecal Fexi-Seal: relato de casos / Rectal ulceration due to using the Fexi-Seal fecal management system: a case report

El Sistema Fexi-Seal es un dispositivo desarrollado para proporcionar mejores cuidados a los pacientes críticos con incontinencia fecal. Existen trabajos que demuestran la seguridad y eficacia del dispositivo, siendo escasos los relatos relacionados con eventos adversos. El presente artículo presenta dos casos de pacientes críticos portadores de Fexi-Seal que desarrollaron complicaciones con su uso. El sistema se mostró eficaz para el tratamiento, sin embargo, es necesaria atención especial en su manejo, particularmente en cuanto al alivio periódico de la presión de la ampolla rectal y al posicionamiento correcto de la bolsa colectora en la cama para evitar tracción excesiva. El Sistema Flexi-Seal permite manejar adecuadamente la diarrea en pacientes críticos, mejorando su bienestar y disminuyendo las complicaciones asociadas a ella, aunque se torna necesario aumentar el conocimiento sobre las complicaciones relacionadas con su empleo.

O Sistema Fexi-Seal é um dispositivo desenvolvido com o objetivo de proporcionar melhores cuidados aos pacientes críticos com incontinência fecal. Existem trabalhos que demonstram a segurança e a eficácia do dispositivo, sendo, porém, escassos os relatos relacionados aos eventos adversos. O presente artigo apresenta dois casos de pacientes críticos portadores de Fexi-Seal que desenvolveram complicações com seu uso. O Sistema mostrou-se eficaz para o tratamento, no entanto, é necessária atenção especial no seu manejo, particularmente quanto ao alívio periódico da pressão na ampola retal e o posicionamento correto da bolsa coletora na cama para evitar tração excessiva. O Sistema Fexi-Seal permite manejar adequadamente a diarreia em pacientes críticos, melhorando o bem-estar e diminuindo as complicações associadas a ela, porém faz-se necessário aumentar o conhecimento sobre as complicações relacionadas ao seu emprego.

The Flexi-Seal Fecal Management System is a device designed to offer improved care to critical care patients with fecal incontinence. Studies have proven the safety and effectiveness of the device, but there are scarce reports on the adverse events. This article presents two cases of critical care patients who developed complications associated with the use of the Flexi-Seal FMS. The System proved to be effective for the treatment; however, it requires special care in the handling, particularly regarding the periodical relief of pressure from the retention balloon and the correct positioning of the collection bag on the bed, so as to avoid excessive traction. The Flexi-Seal is useful to manage diarrhoea in critical patients, improving their well-being and reducing associated complications. Nevertheless, there is a need to improve knowledge related to the complications that may occur.

Ileocolorectal intussusception due to caecal hamartoma / Intususcepción íleocolorectal causada por hamartoma de ciego

Although 75% of intussusceptions occur within the first two years of life, they can also develop in teenage years. This is a case report of a 13-year old boy with an ileocolorectal intussusception from a large caecal hamartoma (10 x 6 x 2 cm3) adjacent to the ileocaecal valve. Partial resection of the ascending colon and terminal ileum was performed, and the pathology of the resected mass revealed a hamartoma. Ileocolorectal intussusception secondary to hamartoma represents a particularly rare event in the paediatric population. With early surgical intervention, this patient's outcome was uneventful.

Aunque el 75% de las intususcepciones ocurren en los primeros dos años de vida, pueden también desarrollarse en el período de la adolescencia. Éste es el reporte del caso de un niño de 13 años con una intususcepción ileocolorectal a partir de un hamartoma de ciego de gran tamaño (10 x 6 x 2 cm3) adyacente a la válvula ileocecal. Se realizó una resección parcial del colon ascendente y el íleo terminal, y la patología de la masa resecada reveló un hamartoma. La intususcepción íleocolorectal derivada secundariamente a partir de un hamartoma, representa un caso particularmente raro dentro de la población pediátrica. Una intervención quirúrgica temprana, hizo posible que este paciente tuviera una evolución clínica sin graves consecuencias.

Endometriosis profunda del tabique rectovaginal con compromiso intestinal: manejo quirúrgico con resección segmentaria de rectosigmoides / Deep infiltrating endometriosis of the rectovaginal space with intestinal commitment: surgical treatment

Presentamos 3 casos de endometriosis profunda del tabique rectovaginal con compromiso intestinal, en los cuales se realizó resección segmentaria del rectosigmoides para lograr la remoción completa de la enfermedad. Se analiza el cuadro clínico, manejo quirúrgico, complicaciones y seguimiento posterior. Revisamos la literatura a fin de establecer algunas pautas de manejo de esta entidad.

We reported 3 cases of deep endometriosis affecting the rectovaginal space with intestinal disease in which a rectosigmoides resection was required to achieve a complete surgical removal of disease. The clinical course, surgical management, complications and follow-up are analyzed. We review the literature to define some guidelines in the management of this entity.

Lesões anorretais em pacientes HIV positivos usuários de terapia anti-retroviral de alta efetividade / Anorrectal lesions in HIV-positive patients using highly active antiretroviral therapy

As lesões anorretais são comuns nos pacientes positivos para o vírus da imunodeficiência humana. A terapia antirretroviral de alta efetividade tem pouca influência na progressão das neoplasias anais. Estudou-se a prevalência das lesões anorretais em 88 pacientes HIV positivos atendidos no serviço de doenças infecto-parasitárias do Hospital Universitário de Brasília, em uso de terapia antirretroviral de alta efetividade. Dados sócio-demográficos foram coletados usando um questionário pré-elaborado e os pacientes foram submetidos a exame proctológico. Cerca de 71 por cento relataram coito anal e 30,7 por cento estavam em uso de inibidor de protease. A prevalência das lesões anorretais foi 36,4 por cento, sendo as mais freqüentes: condiloma acuminado e fissura anal. O condiloma acuminado foi a lesão anorretal mais prevalente e teve associação com o uso de lopinavir/ritonavir. Sugere-se o rastreamento das lesões anorretais causadas pelo papilomavírus humano nos pacientes HIV positivos/AIDS em uso de inibidor de protease.

Anorectal lesions are common in patients with human immunodeficiency virus (HIV). Highly active anti-retroviral therapy (HAART) has little influence on the progression of anal neoplasms. The prevalence of anorectal lesions in 88 HIV-positive patients attended at the infectious diseases service of the University Hospital of Brasília who were using HAART was studied. Sociodemographic data were collected using a pre-prepared questionnaire and then the patients underwent proctological examination. Around 71 percent of the patients said they practiced anal intercourse. 30.7 percent were using a protease inhibitor. The prevalence of anorectal lesions was 36.4 percent, and condyloma acuminata and anal fissure were the most frequent of these. Condyloma acuminata was the most prevalent anorectal lesion and was strongly associated with the use of lopinavir/ritonavir. Screening for anorectal lesions caused by human papillomavirus in HIV/AIDS patients who use protease inhibitors is suggested.

Procedimentos cirúrgicos em pacientes proctológicos selecionados, sob anestesia local: estudo de 150 casos / Surgical procedures in proctological selected patients, with local anesthesia: study of 150 cases

Experience in the treatment of 150 patients with anorectal disorders and disorders of the sacrococcygeal region who were operated on with local anesthesia at the University Hospital, ABC Medical School, Sao Bernardo do Campo, SP, Brazil, from March 1995 to March 1998.
