Os malefícios da "Luva Chupeta" de látex na Unidade Neonatal / The harmful effects of the latex "Glove Pacifier" in the Neonatal Unit / Los efectos nocivos del "Guante Chupete" de látex em La Unidad Neonatal

Na Iniciativa Hospital Amigo da Criança-Neofoi proposto o uso da chupeta na Unidade Neonatal (UN) de modo terapêutico, e sempre com supervisão de um profissional de saúde. Mas observa-se que o aparato conhecido como "Luva Chupeta" fabricado com o uso de uma luva de látex está sendo utilizado como alternativa para acalentar o recém-nascido (RN). Apesar de poucos estudos, é evidente que esse dispositivo deve ser contraindicado na UN, uma vez que pode provocar alergia ao látex, transmitir infecções, provocar acidentes graves como aspiração laringotraqueal do algodão devido ao rompimento da luva de látex, e dependendo do tamanho do material, obstruir as vias aéreas, e levar a óbito. Além do mais, o dispositivo pode interferir negativamente no crescimento e no desenvolvimento craniofacial e causar prejuízos associados à amamentação e na saúde materno infantil. A substituição da "Luva Chupeta" por outras estratégias, até mesmo pela chupeta convencional ou ortodôntica, para lidar com a dor e situações de estresse do RN deve ser decisiva para evitar os riscos de acidentes graves. O Protocolo de uso de bicos, Protocolo de manejo da dor do RN, adoção do Método Canguru na UN para promoção do desenvolvimento e comportamento do RN, e a capacitação/monitoramento das práticas adotas pela Equipe Materno Infantil, quanto ao cuidado ofertado são alternativas mais complexas, mas que devem ser analisadas por aqueles que desejam oferecer confiabilidade aos seus processos institucionais.

In the Baby-Friendly Hospital-Neo Initiative, the use of pacifiers in the Neonatal Unit (UN) was proposed in a therapeutic way, and always under the supervision of a health professional. However, it should be noted that the device known as "Pacifier Glove" manufactured using a latex glove is being used as an alternative to cherish the newborn. Despite few studies, it is clear that this device should be contraindicated in the UN, since it can cause allergy to latex, transmit infections, cause serious accidents such as laryngotracheal aspiration of cotton due to the rupture of the latex glove, and depending on the size of the material, obstruct the airways, and lead to death. Furthermore, the device may interfere with craniofacial growth and development and cause harm associated with breastfeeding and maternal and child health. The substitution of the "Pacifier Glove" for other strategies, even for the conventional or orthodontic pacifier, to deal with the pain and stress situations of the baby should be avoided to avoid the risk of serious accidents.The teat use protocol, the baby's pain management protocol, the adoption of the Kangaroo Method in the neonatal unit to promote the baby's development and behavior, and the training/monitoring of the practices adopted by the Maternal and Child Team, regarding the care offered, are alternatives more complex, but which must be analyzed by those who wish to offer reliability to their institutional processes. (AU)

En la Iniciativa Hospital Amigo del Niño-Neo, se propuso terapéuticamente el uso del chupete en la Unidad Neonatal (UN), y siempre bajo la supervisión de un profesional de la salud. Pero se observa que el dispositivo conocido como "chupete Gluva", fabricado con el uso de un guante de látex, está siendo utilizado como una alternativa para cuidar al recién nacido (NB). A pesar de los pocos estudios, es evidente que este dispositivo debe estar contraindicado en la NU, ya que puede causar alergia al látex, transmitir infecciones, ocasionar accidentes graves como aspiración laringotraqueal de algodón por rotura del guante de látex, y dependiendo de la El tamaño del material obstruye las vías respiratorias y provoca la muerte. Además, el dispositivo puede interferir negativamente con el crecimiento y desarrollo craneofacial y causar daños asociados con la lactancia materna y la salud maternoinfantil. La sustitución del "Dummy Glove" por otras estrategias, incluso el chupete convencional u ortodóncico, para hacer frente a las situaciones de dolor y estrés del RN debe ser determinante para evitar el riesgo de accidentes graves. El Protocolo de Uso del Pezón, el Protocolo de Manejo del Dolor del RN, la adopción del Método Canguro en la NU para promover el desarrollo y comportamiento del RN, y la capacitación/seguimiento de las prácticas adoptadas por el Equipo Materno Infantil, en cuanto a los cuidados ofrecidos, son más alternativas eficientes, complejas, pero que deben ser analizadas por quienes deseen brindar confiabilidad a sus procesos institucionales.

Técnica minimalista para valvuloplastía aórtica percutánea / Minimally invasive balloon aortic valve valvuloplastyBackground

RESUMEN: ANTECEDENTES: La valvuloplastía aórtica es un procedimiento paliativo o como puente al reemplazo aórtico percutáneo o quirúrgico. Nuestro abordaje incluye una técnica minimalista y la utilización de balones de mayor tamaño que lo estándar. OBJETIVO: Evaluar los resultados clínicos inmediatos y alejados de pacientes tratados mediante esta técnica modificada. MÉTODOS: Se incluyó a todos los pacientes sometidos a balonplastía aórtica entre Julio del 2012 y Agosto del 2019 en nuestro centro. El procedimiento se realizó bajo sedación consciente mediante un único acceso femoral y sin instalación de un marcapasos transitorio. El éxito de la intervención se definió como caída de gradiente basal en 50% o más en ausencia de complicación mayor. RESULTADOS: Se realizaron un total de 52 procedimientos en 49 pacientes. La edad promedio fue 76 ± 9,9 años. Un tercio de los pacientes tenía una fracción de eyección del ventrículo izquierdo ≤35% y similar proporción tenía un perfil de riesgo STS score > 10 puntos. La duración total promedio fue de 31,1 + 10,0 min. Se utilizó un balón #28 en el 84.6% de los casos. El éxito del procedimiento se alcanzó en 94,2% de los casos. Ocurrieron 2 muertes intraoperatorias (3,9%), ambas en pacientes de muy alto riesgo y 2 (3,9%) complicaciones vasculares mayores. La sobreviva en el seguimiento alejado fue 32,7%. CONCLUSIÓN: La valvuloplastia aórtica percutánea con técnica modificada, utilizando balones de mayor tamaño que lo habitual, es una técnica segura que logra óptimos resultados hemodinámicos.

ABSTRACT: Aortic balloon valvuloplasty (ABV) is a palliative procedure or a bridge to percutaneous or surgical aortic valve replacement. Our group proposes a minimalist approach that reduces the use of resources and also stands out for using larger balloons. AIM: To assess the safety and the immediate results of patients undergoing aortic balloon valvuloplasty using a minimally invasive procedure. METHODS: All patients who underwent ballon aortic valvuloplasty (BAV) between July 2012 and Au- gust 2019 were included. The procedure was performed under conscious sedation using a single femoral access and without the installation of a temporary pacemaker. Success was defined as a 50% drop in the mean aortic gradient plus the absence of major complications. RESULTS: 52 procedures in 49 patients were performed; the average age was 76 ± 9,9 years. A third of patients included had a left ventricular ejection fraction ≤35% and a similar proportion had a high risk profile with an STS score> 10 points. A 28 mm balloon was used in 84.6% of cases. The procedure was successful in 94,2% of cases. There were 2 (3,85%) intraoperative deaths in very high-risk patients and 2 (3,85%) major vascular complications. The survival rate at late follow up was 32,7%. CONCLUSION: Aortic balloon valvuloplasty with a minimally invasive technique using larger than usual balloons is a safe technique that achieves optimal hemodynamic results.

Abstract | Introduction: The desire to improve one's physical appearance through simple and economical methods has resulted in the indiscriminate application of modeling substances. As a result, iatrogenic allogenosis has emerged as an increasingly prevalent disease in Latin America. Objective: To describe the epidemiological characteristics and adverse effects arising from the use of modeling substances in a group of patients from Cali, Colombia. Materials and methods: We conducted a retrospective review of the medical records of patients who consulted for complications arising from the use of modeling substances during a six-year period. Results: A total of 1,322 patients were included of whom 95.5% were women. Patients' ages ranged from 19 to 83 years, with an average of 39 years. The most infiltrated anatomical site showing adverse effects due to modeling substances was the buttocks. The asymmetry and increased volume of the infiltrated site were the most common signs while pain, mood disturbances, and depression or anxiety were the most commonly perceived symptoms. A total of 41.8% of patients ignored what substances they had received, and 28.5% received biopolymers; these procedures were mostly performed by non-qualified personnel. Conclusions: The care of these patients requires multidisciplinary teams to establish treatment alternatives to improve their quality of life. In addition, the regulation of establishments, as well as the surveillance, inspection, and control of the imports and use of these substances should be warranted.

Análise crítica da indicação da lavagem gástrica em intoxicações atendidas em um hospital de ensino / Critical analysis of gastric lavage indication for poisoning cases attended in a university hospital

Objetivo: Avaliar a indicação da lavagem gástrica no tratamento de intoxicações causadas por ingestão. Métodos: Todos os casos de intoxicação causada por ingestão que foram atendidos em dois hospitais do interior de São Paulo e submetidos à lavagem gástrica no período de 1° de janeiro de 2011 a 31 de dezembro de 2015 foram avaliados retrospectivamente quanto à indicação do procedimento, considerando o tempo entre ingestão e atendimento, a toxicidade da substância e as contraindicações para o procedimento. Resultados: Dos 587 casos atendidos, 338 (57,6%) foram submetidos à lavagem gástrica. Dentre esses casos, constatou-se a realização equivocada do procedimento em 95,8% casos. Conclusão: O número de pacientes submetidos à lavagem gástrica neste trabalho foi considerado elevado, mesmo quando orientado pelo centro de atendimento. Apesar da falta de evidências de que a lavagem gástrica traga benefícios nos casos de intoxicação, ela é largamente utilizada em virtude do desconhecimento das indicações e contraindicações desse procedimento por parte dos profissionais de saúde

Objective: To evaluate the indication of gastric lavage in the treatment of poisoning caused by ingestion. Methods: All cases of poisoning caused by ingestion that were treated in two hospitals in inland cities of São Paulo and subjected to gastric lavage from January 1, 2011 to December 31, 2015 were retrospectively assessed as for the indication of the procedure, considering the time between ingestion and care, substance toxicity, and procedure contraindications. Results: Of the 587 cases treated, 338 (57.6%) underwent gastric lavage. The procedure was considered incorrect in 95.8% of cases. Conclusion: The number of patients undergoing gastric lavage in this study was considered high, even when instructed by the center of attendance. Despite the lack of evidence that gastric lavage brings benefits in cases of poisoning, it is widely used due to the lack of knowledge by health professionals of the indications and contraindications of this procedure.

During which period should we avoid cholecystectomy in patients who underwent endoscopic retrograde cholangiopancreatography? / Durante qual período devemos evitar a colecistectomia em pacientes que realizaram colangiopancreatografia retrógrada endoscópica?

ABSTRACT Objective: To determine the period during which we should avoid cholecystectomy after endoscopic retrograde cholangiopancreatography. Methods: A retrospective analysis of electronic medical charts of 532 patients undergoing endoscopic retrograde cholangiopancreatography, between March 2013 and December 2017. Results: Approximately one-third of patients underwent the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography. The conversion rate was 3.8%. The need for abdominal drainage and the finding of biliary tract injury after surgery were observed in 15.1% and 1.9% of patients, respectively. The length of stay was significantly shorter among patients undergoing surgery more than 30 days after endoscopic retrograde cholangiopancreatography. These patients had a median length of stay of one day, whereas the median length of stay in the group undergoing the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography was 2 days. Conclusion: The period during which we should avoid cholecystectomy is between 4 and 30 days after endoscopic retrograde cholangiopancreatography.

Bypass en Y-de-Roux sobre una funduplicatura de Nissen / Roux-en-Y gastric bypass following Nissen fundoplication

El bypass gástrico en Y-de-Roux (RYGB) trata eficazmente la obesidad y a la vez la enfermedad por reflujo gastroesofágico (ERGE). Desafortunadamente, algunos pacientes que finalmente se presentan para cirugía bariátrica han sido previamente sometidos a una funduplicatura de Nissen por ERGE. La conversión a RYGB después de esta funduplicatura ha demostrado ser segura y eficaz, pero con una mayor morbilidad, tiempo operatorio más prolongado y mayor estancia hospitalaria. Se presenta una paciente de 50 años, con IMC 40,4 kg/m², evaluada para cirugía bariátrica. Había sido sometida a funduplicatura de Nissen laparoscópica siete años atrás. Informamos un caso de eliminación laparoscópica de funduplicatura de Nissen y conversión a RYGB. La funduplicatura previa no es una contraindicación para LRYGB. Estos procedimientos deben ser llevados a cabo por cirujanos experimentados, y el abordaje laparoscópico debe ser el método de elección.

Roux-en-Y gastric bypass (RYGB) effectively treats both obesity and gastroesophageal reflux disease (GERD). Unfortunately, some patients finally present for bariatric surgery have previously undergone Nissen fundoplication due to GERD. Conversion to EYGB after Nissen fundoplication is safe and effective, but is associated with greater morbidity and longer operative time and hospital stay. A 50-year-old female patient with a body mass index (BMI) of 40.4 kg/m² was evaluated for bariatric surgery. She had a history laparoscopic Nissen fundoplication seven years before. We report a case of laparoscopic take-down of Nissen fundoplication and conversion to RYGB. A previous fundoplication is not a contraindication for laparoscopic RYGB. These procedures should be performed by well-trained surgeons and laparoscopic approach should be the method of choice.

Cirugía bariátrica en adolescentes / Bariatric surgery in adolescents

Resumen: La epidemia de obesidad afecta en forma transversal a todo el ciclo vital. En particular, en las últimas décadas se ha observado un incremento de la obesidad severa en adolescentes. En esta etapa de la vida caracterizada por profundos cambios físicos, emocionales y gran vulnerabilidad, la obesidad severa tiene pocas opciones efectivas de tratamiento. En adolescentes, los resultados del tratamiento centrado en modificaciones del estilo de vida son modestos y el arsenal farmacológico muy acotado y de poca efectividad. La Cirugía Bariátrica (CB) ha surgido como una opción terapéutica viable para un grupo seleccionado de adolescentes. El objetivo de esta revisión es presentar una visión actualizada respecto a indicaciones, contraindicaciones, complicaciones y resultados de estos procedimientos en población adolescente.

Abstract: The obesity epidemic affects transversally the entire life cycle. Particularly in recent decades, an in crease in severe obesity has been observed in adolescents. At this stage of life, characterized by deep physical and emotional changes, and great vulnerability, severe obesity has few effective treatment options. In adolescents, the treatment results focused on lifestyle modifications are poor and the pharmacological options are very limited and ineffective. Bariatric Surgery (BS) has emerged as a via ble therapeutic option for a selected group of adolescents. The objective of this review is to update the current view regarding indications, contraindications, complications, and results of these procedures in the adolescent population.

Aplicaciones médicas de las cámaras de oxigenación hiperbárica de nueva generación / Medical applications of new generation hyperbaric oxygenation chambers

El uso clínico de la terapia de oxigenación hiperbárica (TOHB) consiste en respirar oxígeno en una concentración cercana al 100% en una cámara presurizada al menos a 1,4 atmósferas absolutas (atm). TOHB actúa produciendo hiperoxia y especies reactivas del oxígeno que desencadenan mecanismos bioquímicos variados. Se presenta una revisión de todas las nuevas aplicaciones emergentes de TOHB en varias especialidades médicas debido a que alcanza beneficios en la cicatrización de heridas, enfermedades inflamatorias y con componente neurológico o isquémico. Las nuevas cámaras realizan el tratamiento a presiones más seguras y con la misma eficiencia demostrada por métodos matemáticos y bioquímicos. El Grupo BioBárica Clinical Research presenta la estadística de las indicaciones en 559 pacientes tratados con estas cámaras en algunos centros médicos y las especialidades médicas implicadas. El uso de TOHB a media presión está en emergencia y podría proveer a futuro evidencia de su efectividad en otras especialidades médicas. (AU)

The clinical use of Hyperbaric Oxygen Therapy (HBOT) consists in breathing oxygen (O2) near to 100% in a pressurized chamber of at least at 1.4 absolute atmospheres (ATA). HBOT acts producing both hyperoxia and reactive oxygen species (ROS) and triggers others biochemical events. The BioBarica Clinical Research Group is developing clinical evidence in diverse pathologies because of accessibility and safety of the new Revitalair hyperbaric oxygen chamber. Because of working at "mild pressure", HBOT performed by these chamber are safer demonstrated by mathematical and biochemical methods. The BioBarica Clinical Research Group presents the statistics of the indications in 559 patients treated with these cameras in some medical centers and the medical specialties involved. Their accessibility to the physicians would become mild pressure HBOT used more frequently proving its effectiveness in other clinical specialties. (AU)

Florid cemento-osseous dysplasia: a contraindication to orthodontic treatment in compromised areas

ABSTRACT Florid cemento-osseous dysplasia is a sclerosing disease that affects the mandible, especially the alveolar process, and that is, in most cases, bilateral; however, in some cases it affects up to three or even four quadrants. During the disease, normal bone is replaced with a thinly formed, irregularly distributed tissue peppered with radiolucent areas of soft tissue. Newly formed bone does not seem to invade periodontal space, but, in several images, it is confused with the roots, without, however, compromising pulp vitality or tooth position in the dental arch. There is no replacement resorption, not even when the images suggest dentoalveolar ankylosis. Orthodontists should make an accurate diagnosis when planning treatments, as this disease, when fully established, is one of the extremely rare situations in which orthodontic treatment is contraindicated. This contraindication is due to: (a) procedures such as the installment of mini-implants and mini-plaques, surgical maneuvers to apply traction to unerupted teeth and extractions should be avoided to prevent contamination of the affected bone with bacteria from the oral microbiota; and (b) tooth movement in the areas affected is practically impossible because of bone disorganization in the alveolar process, characterized by high bone density and the resulting cotton-wool appearance. Densely mineralized and disorganized bone is unable to remodel or develop in an organized way in the periodontal ligaments and the alveolar process. Organized bone remodeling is a fundamental phenomenon for tooth movement.

RESUMO A displasia cemento-óssea florida é uma doença óssea esclerosante exclusiva dos maxilares, relacionada ao osso do processo alveolar e, na maioria dos casos, envolvendo bilateralmente a mandíbula; mas há casos em que envolve três ou até os quatro quadrantes. Nesse processo, troca-se o osso normal por um tecido densamente formado, irregularmente distribuído e salpicado por áreas radiolúcidas com tecido mole. O osso neoformado parece não invadir o espaço periodontal, mas, em muitas imagens, confunde-se com as raízes, sem comprometer a vitalidade pulpar e a posição dentária na arcada. Não há reabsorção dentária por substituição, mesmo quando as imagens sugerem anquilose alveolodentária. Um diagnóstico preciso por parte do ortodontista deve ser feito em seus planejamentos, visto que essa doença, quando se encontra plenamente instalada, representa uma das raríssimas situações em que o tratamento ortodôntico está contraindicado. Nesses casos, o tratamento ortodôntico está contraindicado porque: a) alguns procedimentos, como a aplicação de mini-implantes e miniplacas, manobras cirúrgicas para tracionamento de dentes não irrompidos e exodontias, devem ser evitados, para se impedir a entrada de bactérias da microbiota bucal no osso comprometido; e b) a possibilidade de movimentação dos dentes nas áreas comprometidas praticamente inexiste, pela desorganização óssea no processo alveolar, caracterizada por elevada densidade óssea, que gera as imagens tipo flocos de algodão. O osso densamente mineralizado e desorganizado não é capaz de se remodelar e desenvolver organizadamente, nos ligamentos periodontais e no osso do processo alveolar. A remodelação óssea organizada é fundamental como um dos fenômenos necessários para o deslocamento dos dentes.

Pellucid marginal degeneration: postponing penetrating keratoplasty for over a decade / Degeneração marginal pelúcida: postergando o transplante de córnea em mais de uma década

Abstract Pellucid marginal degeneration (PMD) treatment can be challenging in moderate to advanced cases and penetrating keratoplasty should be avoided due to high risk of complications, such as graft rejection. We report a case of a 30-year-old female patient with PMD that was referred to our service with bilateral low visual acuity, worse in her right eye and contact lenses intolerance. We performed a corneal crescentic lamellar wedge resection that resulted in good useful vision and postponed the keratoplasty for eighteen years.

Resumo A degeneração marginal pelúcida (DMP) é uma ectasia corneana de difícil manejo em casos moderados e avançados. O transplante de córnea penetrante nesses pacientes deve ser evitado ao máximo tendo em vista que a descentração necessária do botão aumenta o risco de vascularização e consequentemente rejeição, além das dificuldades técnicas e possibilidade de deiscência de sutura devido ao afinamento corneano pronunciado característico desta ectasia. Nós relatamos o caso de uma paciente de 30 anos com DMP com queixa de baixa visual bilateral, pior no olho direito e intolerância a lentes de contato. Foi realizada ressecção lamelar em crescente neste olho, com excelente resultado, concedendo visão útil a paciente e postergando o transplante penetrante por dezoito anos.

Burkholderia cepacia, cystic fibrosis and outcomes following lung transplantation: experiences from a single center in Brazil

OBJECTIVES: To evaluate the impact of Burkholderia cepacia complex colonization in cystic fibrosis patients undergoing lung transplantation. METHODS: We prospectively analyzed clinical data and respiratory tract samples (sputum and bronchoalveolar lavage) collected from suppurative lung disease patients between January 2008 and November 2013. We also subtyped different Burkholderia cepacia complex genotypes via DNA sequencing using primers against the recA gene in samples collected between January 2012 and November 2013. RESULTS: From 2008 to 2013, 34 lung transplants were performed on cystic fibrosis patients at our center. Burkholderia cepacia complex was detected in 13 of the 34 (38.2%) patients. Seven of the 13 (53%) strains were subjected to genotype analysis, from which three strains of B. metallica and four strains of B. cenocepacia were identified. The mortality rate was 1/13 (7.6%), and this death was not related to B. cepacia infection. CONCLUSION: The results of our study suggest that colonization by B. cepacia complex and even B. cenocepacia in patients with cystic fibrosis should not be considered an absolute contraindication to lung transplantation in Brazilian centers.

Retrospective analysis of the elective tests of rigid proctosigmoidoscopy performed in the service of medical residency in Coloproctology of Hospital Santa Marcelina / Análise retrospectiva de exames eletivos de retossigmoidoscopia rígida realizadas no serviço de residência médica de Coloproctologia no Hospital Santa Marcelina

Introduction: Proctologic examination is a deeply intimate procedure which deals with a body area in which prejudices, taboos and constraints prevail, and may also relate to previous trauma; yet this procedure is of paramount importance for the investigation of patients with symptoms that foretell pathologies associated with distal colon, rectum and anus. Objectives: This study aimed to analyze all cases scheduled of rigid proctosigmoidoscopy performed by the Coloproctology Service, Hospital Santa Marcelina, in 8 of its 10 years of residency in the specialty. Materials and methods: We analyzed mean age, gender distribution, device's height of reach in relation to the anal verge, the percentage of abnormal tests stratified to perform, or not perform, anoscopy and proctosigmoidoscopy, and major diseases detected. Results: 844 rigid proctosigmoidoscopy procedures scheduled and performed by the Coloproctology Service, Hospital Santa Marcelina, between September 2006 and August 2014, were analyzed. The distribution was similar between genders and the mean age was 51.2 years. With respect to the device's height of reach from the anal verge, these values were stratified as follows: distance reached >15 cm, 10-15 cm, and <10 cm from the anal verge. Distances >15 cm from the anal verge were attained in 692 (82% of RR) tests, between 10 and 15 cm in 94 (11.1%) tests, and <10 cm in 58 (6.9%) tests. Conclusion: In this study, it was found that proctology examination and rigid proctosigmoidoscopy are mandatory procedures in cases of symptoms depending on these practices.

Introdução: O exame proctológico, apesar de profundamente íntimo e de lidar com área do corpo na qual imperam preconceitos, tabus e constrangimento, podendo inclusive relacionar-se a traumas prévios, é de suma importância para a investigação de pacientes com sintomas que predizem patologias associadas ao cólon distal, reto e ânus. Objetivos: Analisar todos os casos de retossigmoidoscopias rígidas realizadas de forma agendada pelo serviço de Coloproctologia do Hospital Santa Marcelina em 8 de seus 10 anos de residência médica na especialidade. Materiais e métodos: Analisou-se a média de idade, distribuição por sexo, altura de alcance do aparelho em relação à borda anal, percentagem de exames anormais com estratificação quando realizado ou não a anuscopia e retossigmoidoscopia e as principais doenças detectadas. Resultados: Foram avaliadas 844 retossigmoidoscopias rígidas realizadas pelo serviço de Coloproctologia do Hospital santa Marcelina, de forma agendada, entre setembro de 2006 e agosto de 2014. A distribuição foi semelhante entre os sexos e a média de idade foi de 51,2 anos. Com relação à altura em relação à borda anal, estratificou-se esses valores em maior que 15 cm, entre 10 e 15 cm da borda anal e alcance inferior a 10 cm da borda anal. Em 692 exames foi possível alcance superior a 15 cm da borda anal (82% das RR), em 94 (11,1%) entre 10 e 15 cm, e em 58 (6,9%) exames, abaixo de 10 cm. Conclusão Verificou-se em nosso estudo que o exame proctológico e a retossigmoidoscopia rígida são mandatório em casos de sintomatologia que assim o necessitem.
