Células glandulares atípicas: abordagem ginecológica / Atypical glandular cells: gynecological approach

As células glandulares atípicas representam 0,2% a 2,1% dos resultados dos testes de Papanicolaou. Mesmo com essa baixa prevalência, tem um significado importante no diagnóstico do câncer cervical e endometrial, tendo em vista que tais células e subcategorias, associadas à idade da paciente, podem prenunciar um número expressivo de doença intraepitelial, doença invasiva do endocérvix, endométrio e até neoplasias anexiais. E não se pode esquecer do importante número de resultados histológicos benignos, identificados no seguimento dessas pacientes, muitas vezes assintomáticas.(AU)

Atypical glandular cells represent 0,2% to 2,1% of Pap test results even with this low prevalence has an important significance in the diagnosis of cervical and endometrial cancer, considering that such cells and subcategories associated with the patient's age can predict a significant number of intraepithelial disease, invasive disease of the endometrium, endocervix and even adnexial neoplasms; no forgetting the important number of benign histological results, identified in the follow up of these patients, often asymptomatic.(AU)

Adenocarcinoma cervical in situ: abordagem na atenção primária e secundária à saúde / Cervical adenocarcinoma in situ: approach in primary and secondary health care

O adenocarcinoma cervical in situ é uma doença rara, totalmente curável, diagnosticada predominantemente por meio de rastreamento cervicouterino seguido de biópsia guiada por colposcopia e/ou conização. O tratamento em pacientes que desejam preservar a fertilidade pode ser realizado num contexto ambulatorial; aquelas com paridade definida deverão ser abordadas em nível terciário.(AU)

Cervical adenocarcinoma in situ is a rare, fully curable disease diagnosed predominantly through cervical-uterine screening followed by colposcopy-guided biopsy and/or conization. Treatment in patients wishing to preserve fertility may be performed in an outpatient setting; those with defined parity should be approached at the tertiary level.(AU)

Cirugía mínimamente invasiva transanal (TAMIS): técnica y resultados de la experiencia inicial / Transanal minimally invasive surgery (TAMIS): technique and results of initial experience

Resumen Antecedentes: la cirugía transanal endoscópica es un abordaje mínimamente invasivo recientemente descrito, que provee una exposición superior y permite el acceso a las lesiones del recto en toda su extensión. Además, provee un riesgo menor de compromiso de los márgenes de resección, menores tasas de recurrencia y una menor morbimortalidad en comparación con la escisión transanal convencional o las remociones endoscópicas. Objetivos: se pretende describir la experiencia inicial y los resultados con la cirugía transanal mínimamente invasiva (transanal minimally invasive surgery, TAMIS) en términos de resecciones completas y posibles complicaciones relacionadas con el procedimiento. Materiales y métodos: esta una serie de casos con un seguimiento prospectivo de los pacientes con TAMIS. Se analizaron los resultados de 27 pacientes intervenidos en varios centros de Medellín, Colombia, entre enero de 2012 y diciembre de 2016, realizados con cirugía laparoscópica monopuerto (single-port laparoscopic surgery, SILS) (21 casos) o el GelPOINT® Path (6 casos), junto con el apoyo de la óptica del laparoscopio (16 pacientes) y del endoscopio flexible (11 pacientes). Resultados: se realizaron 27 TAMIS en el mismo número de pacientes, 10 mujeres (37 %) y 17 hombres fueron evaluados. Se realizó un seguimiento a los pacientes durante aproximadamente 12 meses, en promedio 32 meses. La edad promedio fue de 68 años (52-83 años). El tamaño promedio del tumor fue de 5,3 cm (2-9 cm) y la distancia promedio desde el margen anal fue de 7 cm (5-9 cm) Las complicaciones posoperatorias se dieron en 6 casos (22 %) Una perforación rectal se corrigió por vía laparoscópica en el mismo acto quirúrgico y otra por la misma vía transanal. Una estenosis rectal se manejó con dilatación digital, y hubo un caso de sangrado rectal menor, uno de retención urinaria y un paciente presentó un cáncer rectal avanzado a los tres meses de la resección con margen microscópico positivo (4 %). No hubo reingresos. La mortalidad por la intervención fue nula. La patología operatoria reportó la presencia de adenoma de bajo grado en 3 casos (11 %), de alto grado en 11 (41 %), adenocarcinoma in situ en 6 (22 %), tumor neuroendocrino en 5 pacientes (18 %), 1 caso de fibrosis cicatricial (4 %) y 1 de leiomioma (4 %). Limitaciones: los resultados no son extrapolables a la población general debido al poco número de intervenciones y la ejecución limitada a solo dos autores. Conclusiones: en nuestra experiencia inicial, TAMIS es un procedimiento mínimamente invasivo con una baja morbilidad posoperatoria, es curativa para lesiones benignas y para pacientes seleccionados con cáncer temprano.

Abstract Background: Transanal endoscopic surgery, a recently described minimally invasive approach, provides superior exposure and access to the entirety of rectal lesions and has lower risks of compromising resection margins, lower recurrence rates and lower morbidity and mortality than do conventional transanal excision and endoscopic removals. Objectives: The aim of this study is to describe our initial experience and with minimally invasive transanal surgery (TAMIS) and its results in terms of complete resections and complications possibly related to the procedure. Materials and methods: This is a series of TAMIS cases with prospective follow-ups. We analyzed the results of 27 patients who underwent the procedure at several centers in Medellín, Colombia, between January 2012 and December 2016. Twenty patients had Single Incision Laparoscopic Surgery while the GelPOINT path transanal access platform was used for the other six patients. Laparoscope optics provide support for 16 procedures while the more recently introduced flexible endoscope supported eleven procedures. Results: Twenty-seven TAMIS procedures were performed and evaluated. Ten patients were women (37%), and 17 were men. On average, patients were followed up for 32 months, but none less than 12 months. Average patient age was 68 years (52 to 83 years). The average tumor size was 5.3 cm (2 to 9 cm) and the average distance from the anal margin was 7 cm (5 to 9 cm). Postoperative complications occurred in six cases (22%). In one case, a rectal perforation was corrected laparoscopically during the procedure. Another perforation was corrected by the same transanal route. A rectal stenosis was managed with digital dilatation, there was one case of minor rectal bleeding, one case of urinary retention and one patient developed advanced rectal cancer with a positive microscopic margin (4%) three months after resection. There were no readmissions. There were no deaths due to the intervention. Pathology reported low grade adenomas in three cases (11%), high grade adenomas in 11 cases (41%), in-situ adenocarcinoma in six cases (22%), neuroendocrine tumors in five cases (19%), and one case each of cicatricial fibrosis (4%) and leiomyoma (4%). Limitations: The results cannot be extrapolated to the general population because of the limited number of interventions and performance of procedures by only two authors. Conclusions: Our initial experience shows TAMIS to be a minimally invasive procedure with low postoperative morbidity which is curative for benign lesions and for selected patients with early cancer.

Factors associated with abnormalities of the cytopathological uterine cervix test in South of Brazil / Fatores associados a alterações do exame citopatológico cérvico-uterino no Sul do Brasil

Abstract Objectives: to identify factors associated with abnormal cytopathological test uterine cervix. Methods: it is a analytical study with the participation of 390 women who presented abnormal cytopathological from a city in the state of Paraná in 2012. They were randomly selected through sampling plan. Sociodemographic information such as age, marital status, education level and ethnicity were considered independent variables while the high or low-grade cytological lesions as dependent variable. We analyzed the data statistically by Yates Corrected test, Fisher exact test and measures of association by odds ratio. For all analyzes was considered significance level of 5% and 95% confidence interval. Results: the mean age was 38.8 years, 72.9% were married or common-law marriage, 49.7% with low education level and 87.4% race/color white. HPV contamination was detected in 49.7% of women and high-grade cytological lesions in 18.2%. The low educa-tional level (95%OR=4.07) and non-white ethnicity (95%OR=2.22) were strongly associated with the development to cervical lesions (p<0.05). Conclusions: sociodemoghaphic characteristics were crucial to high-risk lesions and development of cervical cancer, especially in women with low educational level and race/color black or brown. These results confirm the persistence of diseases related to preventable and avoidable causes in the country.

Resumo Objetivos: identificar os fatores associados com alterações do exame citopatológico cérvico-uterino. Métodos: trata-se de um estudo analítico com participação de 390 mulheres que apresen-taram alterações citopatológicas em município do Estado do Paraná no período de 2012. Elas foram selecionadas aleatoriamente através de plano amostral. Informações sociode-mográficas como idade, estado civil, grau de escolaridade e etnia foram consideradas variáveis independentes enquanto que o alto ou baixo grau de lesão citológica como variável dependente. Analisaram-se os dados estatisticamente pelos Testes de Yates corrigido e Fisher e medidas de associação pela odds ratio. Para todas as análises considerou nível de significância de 5% e intervalo de confiança 95%. Resultados: a idade média foi de 38,8 anos sendo a maioria casada ou união estável (72,8%) e com baixa escolaridade (42,8%) e raça/cor branca (87,4%). A contaminação pelo HPV foi detectada em 49,7% das mulheres e lesões citológicas de alto grau em 18,2%. A baixa escolaridade (OR95%=4,07) e etnia não branca (OR95%=2,22) estiveram fortemente associadas ao desenvolvimento às lesões de colo uterino (p<0,05). Conclusão: características sociodemográficas foram determinantes para lesões de alto risco e desenvolvimento de câncer de colo uterino, especialmente nas mulheres de baixa escolaridade e raça/cor negra ou parda. Estes resultados confirmam a persistência de doenças por causas evitáveis e reduzíveis no país.
