“…A colonoscopia complementa achados radiológicos duvidosos e permite localizar a região anatômica e realização de biópsias em lesões que não são alcançadas pela retossigmoidoscopia, que indicarão ou não a necessidade de intervenção cirúrgica (MENEZES et al, 2016). O enema opaco ou clister opaco atualmente tem seu uso restrito a um número menor e mais específico de casos, mas realizado junto com a colonoscopia possui relevância em alguns casos (CARTANA et al, 2016;DIOGENES et al, 2007). (PRIOLLI et al, 2007;ANDRADE & PEREIRA, 2007).…”

Resumo O câncer colorretal está entre as neoplasias malignas que mais acometem pacientes no Brasil e no mundo. Seu diagnóstico precoce permite um tratamento mais eficaz e um prognóstico muito bom para o paciente, mas é dificultado pela generalidade dos sinais e sintomas ligados ao câncer colorretal, uma vez que também estão relacionados a outras patologias. Sua fisiopatologia apresenta características de desenvolvimento semelhantes a da maioria das lesões neoplásicas, mas com seu desenvolvimento silencioso e dependendo da localização da lesão, o diagnóstico pode demorar anos para ser realizado, muitas vezes acontecendo tardiamente. O diagnóstico sempre está ligado a exames endoscópios, principalmente a colonoscopia, aliados a exame físico e clínico, e a realização de biópsias que confirmam a presença do carcinoma colorretal e indicam a melhor saída para o tratamento cirúrgico. Esse trabalho busca, por meio de revisão da literatura, esclarecer as formas mais adequadas e que são empregadas no diagnóstico de câncer colorretal, através da pesquisa de artigos em site de busca acadêmica: Pubmed e Scielo. Após análise dos dados compilados da literatura fica claro que o correto diagnóstico anatomopatológico, bem como o estadiamento no momento da intervenção cirúrgica é de extrema importância, tanto para a definição do tratamento, quanto para o prognóstico dos pacientes. Adicionalmente o diagnóstico precoce, quer pela imediata investigação de sintomas suspeitos quer pelo rastreio da população e de grupos de risco, permite diminuir a mortalidade em pacientes com câncer colorretal.

Purpose To assess the feasibility and effectiveness of the fecal occult blood test (FOBT) and flexible rectosigmoidoscopy (RSS), as tools used in the CRC screening, in asymptomatic patients, from 50 years of age. Methods The study is transversal and presents a sample of 102 individuals. The FOBT used was the guaiaco, FECA-CULT® method, held at a single time, in feces collected from a complete evacuation. Individuals, who presented the positive FOBT, were sent to colonoscopy complement, although this is not primary variable examined in this study. All subjects underwent to flexible RSS, after bowel preparation, using a solution of sodium phosphate monobasic monohydrate and dibasic sodium phosphate heptahydrate. Results Individuals showed minimum age of 50 years and maximum 82 years, 61.6 years average and standard deviation +8.1. Of the 102 individuals, 42 (41%) belong to the males, whereas 60 (58.8%) female. The FOBT presented 10 positive cases (9.8%) (IC 95%: 4.8–17.3%) and 92 negative cases (90.2%) (IC 95%; 82.7–95.2%). The FOBT was effective at 2.9% and presented false-positive result in 6.9%. The result of the FBOT association with flexible RSS showed that 70% of neoplastic polyps showed no bleeding. Its sensitivity was 30% (IC 95%: 0.00–63.40%), the value of the relative risk was 3.94 (IC 95%: 1.20–12.89) and 5.20 valued odds ratio (IC 95%: −23.15 to 1.21). The specificity was 92.40% (IC 95%: 86.43–98.35%). The flexible RSS detected 15 polyps, among which, after histopathological study, 10 were neoplastic, being 09 adenomatous polyps (60%) and 01 malignity (6.7%) (IC 95%: 0.20–31.90%) and 05 non-neoplastic polyps (33.3%), and 03 inflammatory polyps (20%) (IC 95%: 4.3–48.1%) and 02 hyperplastic polyps (13.3%) (IC 95%: 1.7–40.5%). Neoplastic polyps were present in 60% of individuals over 60 years of age. Among the adenomatous polyps, the adenomatous polyp tubular prevalence is 53.33%. Among the 102 individuals, flexible RSS detected 09 adenomatous polyps (8.82%) and 01 (0.98%) malignity polyp. Conclusion The tools FOBT and flexible RSS presented feasibility and, when associated demonstrated statistical significance in detecting polyps in general and important clinical significance on the detection of adenomatous polyps and colorectal cancer.

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.
