Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

The association between anthropometric indicators and colorectal polyps and diverticulosis

Introduction: Colonic polyps and diverticulosis are common colon findings on colonoscopy. One of the risk factors of colorectal polyps and diverticulosis is the anthropometric index. Therefore, we aimed to investigate the association between the anthropometric index and colorectal findings. Methods: In this cross-sectional study, we included 536 patients referred to Razi Hospital, Rasht, Iran, in 2023 for colonoscopy evaluation. Demographical data, clinical characteristics, and colonoscopy findings were recorded for further analysis. All data were analyzed using SPSS.16 by considering a significant level < 0.05. Results: The results showed that 35.4% of the patients had polyps, with the majority having a single polyp. The patient's mean age was 55.94 ± 13.33 years; most were females (54.1%). The most common type of polyp was pedunculated, and most were located in the sigmoid colon. The prevalence of diverticular was 11.4%, most of which were also located in the sigmoid colon. Obesity was significantly associated with an increased risk of polyps, while overweight individuals had a higher risk of diverticula (P < 0.05). Age, rural residence, and low physical activity level were identified as factors associated with an increased risk of polyps and diverticula. Conclusion: The findings suggest that obesity and overweight are risk factors for polyps and diverticula, respectively. Further research is warranted to explore additional factors and develop preventive strategies for colorectal diseases. These results support the need for preventive strategies and screening programs to reduce the risk of future colorectal lesions. (AU)

Importância do diagnóstico por imagem em pacientes com sangramento uterino anormal / Importance of diagnostic imaging in patients with abnormal uterine bleeding

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.

Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

Identification and reporting of anal pathology during routine colonoscopies

The gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.

Prevalence of abnormal uterine bleeding according to the International Federation of Gynecology and Obstetrics Classification (PALM-COEIN) among reproductive-aged women admitted in a tertiary hospital in Las Piñas

Objective@#To determine the prevalence of the causes of abnormal uterine bleeding based on the FIGO (PALM-COEIN) Classification, among patients admitted at a tertiary hospital in Las Pinas City@*Methods@#A cross sectional (retrospective) study was done. Patients aged 15-50 years old who were admitted due to abnormal uterine bleeding from January 2017 to December 2019 were included. Patients with AUB due to pregnancy, vaginitis, bleeding before menarche, and bleeding after menopause were excluded from the study. Patient’s data as to age, obstetrical score, co-morbidity, bleeding patterns were tabulated.@*Results@#A total of 455 subjects were included in the study. Results showed that the most common causes of abnormal uterine bleeding among admitted patients in Perpetual Help Medical Center Las Piñas from January 2017 – December 2019 were due to structural causes (91%). Most prevalent was bleeding due to polyps (50.5%), followed by adenomyosis (18.8%), leiomyoma (16.04%), and malignancy (6.2%). Prevalence of non-structural causes of bleeding was 0.4% for coagulopathy, 3.3% due to ovulatory dysfunction, 4.6% due to endometrial dysfunction, and 0.2% for AUB-N.@*Conclusion@#Based on this 3-year retrospective study, structural causes are the most common causes of AUB, comprising about 91% of all patients admitted for AUB. The most common structural causes are AUB-P (50.5%), followed by AUB-A, AUB-L and AUB-M. Prompt recognition of the causes of AUB is very important, to prevent complications such as severe anemia and shock. Proper treatment, be it surgical or medical, also depends on the exact cause of AUB.

Clinical analysis of 102 cases of pediatric vocal fold nodules / 临床耳鼻咽喉头颈外科杂志

Objective:To evaluate the impact of vocal fold nodules on the quality of life of children, and to compare the efficacy between conservative management（voice hygiene education, etc.） and laryngeal microsurgery. Methods:A retrospective study was performed on 102 children with vocal fold nodules, who received treatment in Children's Hospital of Fudan University during the period from January 2020 to December 2022. According to the regime, the patients were divided into conservative management group and surgical treatment group; Cases are divided into pre-school age group （2-5 years old） and school-age group （6-12 years old） based on age. The pediatric voice-related quality of life （pVRQOL） was used to evaluate the impact of vocal fold nodules on the quality of life of children and differences in efficacy between two treatment regimens. Results:The pVRQOL scores of vocal fold nodule grades 1, 2, and 3 were 91.58±8.17, 78.87±12.49, 72.50±12.08, respectively. There were statistical differences between grade 1 and grade 2, and between grade 2 and grade 3. There were statistical differences between grade 1 grade 2, grade 2 and grade 3 （P<0.001）, suggesting that the higher the rating of vocal cord nodules, the lower the pVRQOL score of patients was. The pVRQOL score of the school-age group was 69.83±11.11, which is lower than that of the preschool group（87.59±8.63）, and the difference was statistically significant （P=0.042）. Vocal fold nodules had a significant impact on the pVRQOL score of school-age children. In the conservative management group, the pVRQOL scores before and after treatment were 83.99±12.66 and 87.26±9.58, respectively, and there was significant difference between the two groups（P=0.046）. Indirect voice therapy such as voice hygiene education could improve children's pVRQOL scores and was more effective for school-age children（P<0.001）. The microsurgical treatment had a more significant improvement in the pVRQOL score of children. Conclusion:The higher the rating of vocal fold nodules, the greater the impact on the quality of life of patients. Vocal fold nodules had a greater impact on the quality of life of school-age children than that of preschool children. Voice hygiene education could improve the quality of life of children, which was more evident in the school-age group. Compared with voice hygiene therapy, laryngeal microsurgery had a more significant effect on improving the pVRQOL score of patients. It is recommended to undergo laryngeal microsurgery for the treatment of vocal fold nodules for the requirement of improving the quality of life related to voice. During the 6-month follow-up period after surgery in this study, the short-term efficacy of laryngeal microsurgery in treating vocal cord nodules in children is clear, but the long-term efficacy needs further research.

Metástasis de cáncer de células claras renal en cuerdas vocales. Reporte de un caso / Metastasis of renal clear cell carcinoma in vocal cords. A Case report

Introducción: Las metástasis a distancia de tumores primarios a cuerdas vocales son poco frecuentes. Las metástasis a laringe con mayor frecuencia corresponden a melanomas y carcinomas, afectando principalmente a la región supraglótica. Las metástasis a cabeza y cuello de los carcinomas de células renales (CCR) tienen una incidencia de 14-16%. Se presenta el caso de un paciente con metástasis de carcinoma de células claras renal a cuerdas vocales, cuya importancia recae en que es un caso poco frecuente y no existen reportes similares en el país. Paciente masculino, 57 años, con disfonía de 3 meses de evolución. Nasofibroscopía evidencia lesión polipoídea en cuerda vocal y ventrículo izquierdo. Se realiza microcirugía laríngea, enviando muestra a biopsia diferida, resultando lesión metastásica de CCR células claras. Evaluado por nefrología, se pesquisa tumor renal izquierdo sugerente de CCR. Las metástasis de neoplasias remotas a laringe son infrecuentes. Se considera al CCR el tercero en frecuencia respecto a neoplasias infraclaviculares. Éstas se pueden presentar hasta 10 años después del tratamiento del primario. Se recomienda seguimiento a largo plazo y énfasis a nuevos síntomas en región de cabeza y cuello, teniendo en consideración antecedente de CCR en pacientes con disfonía y lesiones polipoídeas en cuerdas vocales.

Introduction: The metastasis of distant site primary tumors to the vocal cords is infrequent. The most frequent source of metastasis to the larynx is melanomas and carcinomas, mainly affecting the supraglottic region. The metastasis to the head and neck of renal cell carcinomas (RCC) has an incidence of 14-16%. To present a case of metastasis of clear renal cell carcinoma to the vocal cords, since it is very infrequent, and there are no similar reports in the country. A male patient, 57 years old, presenting dysphonia for a duration of 3 months. Nasofibroscopy showed a polypoid lesion in the left vocal cord and ventricle. Larynx microsurgery was performed, and a sample was sent for biopsy, which reported a metastatic lesion of RCC clear cells. When assessed by nephrology, a left renal tumor is found, suggesting RCC. The metastasis of distant site neoplasias are infrequent. RCC is considered the third in frequency concerning to infraclavicular neoplasias. These can present up to 10 years after the treatment of the primary. Long term follow-up is recommended, and an emphasis on new symptoms in the head and neck region, considering the history of RCC in patients with dysphonia and polypoid lesions in vocal cords.

Gallbladder polyps: correlation and agreement between ultrasonographic and histopathological findings in a population with high incidence of gallbladder cancer / Pólipos da vesícula biliar: correlação e concordância entre achados ultrassonográficos e histopatológicos em uma população com alta incidência de câncer de vesícula biliar

ABSTRACT BACKGROUND: Gallbladder polyps are becoming a common finding in ultrasound. The management has to consider the potential risk of malignant lesions. AIMS: The aim of this study was to analyze the ultrasound findings in patients undergoing cholecystectomy due to gallbladder polyps and compare them for histopathological findings (HPs). METHODS: Patients with an ultrasonographic diagnosis of gallbladder polyp and who underwent cholecystectomy from 2007 to 2020 were included in the study. RESULTS: A total of 447 patients were included, of whom 58% were women. The mean age was 45±12 years. The mean size of polyps in US was 7.9±3.6 mm. Notably, 9% of polyps were greater than 10 mm, and single polyps were significantly larger than the multiple ones (p=0.003). Histopathological findings confirmed the presence of polyps in 88.4%, with a mean size of 4.8±3.4 mm. In all, 16 cases were neoplastic polyps (4.1%), 4 of them being malignancies, and all were single and larger than 10 mm. We found a significant correlation between ultrasound and histopathological findings polyp size determination (r=0.44; p<0.001). The Bland-Altman analysis obtained an overestimation of the US size of 3.26 mm. The receiver operating characteristic (ROC) curve analysis between both measures obtained an area under the receiver operating characteristic curve (AUC) of 0.77 (95%CI 0.74-0.81). Ultrasound polyps size larger than 10 mm had an odds ratio (OR) of 8.147 (95%CI 2.56-23.40) for the presence of adenoma and malignancy, with a likelihood ratio of 2.78. CONCLUSIONS: There is a positive correlation and appropriate diagnostic accuracy between ultrasound size of gallbladder polyps compared to histopathological records, with a trend to overestimate the size by about 3 mm. Neoplastic polyps are uncommon, and it correlates with size. Polyps larger than 10 mm were associated with adenoma and malignancy.

RESUMO RACIONAL: Os pólipos da vesícula biliar estão se tornando um achado comum na ultrassonografia (US). O manejo deve levar em consideração o risco de lesões malignas. OBJETIVOS: Analisar os achados da ultrassonografia em pacientes submetidos à colecistectomia por pólipos vesicais e compará-los com os achados histopatológicos. MÉTODOS: Foram revisados os prontuários médicos dos pacientes com diagnóstico ultrassonográfico de pólipo vesicular e submetidos à colecistectomia no período de 2007 a 2020. RESULTADOS: Foram incluídos no estudo 447 pacientes. A média de idade foi 45±12anos, sendo 58% mulheres. O tamanho médio dos pólipos na US foide 7,9±3,6mm. Nove por cento foram maiores que 10 mm, e os pólipos únicos encontrados foram maiores do que os múltiplos (p=0,003). A HP confirmou a presença de pólipos em 88,4%, tamanho médio 4,8±3,4mm. Dezesseis eram pólipos neoplásicos (4,1%) e quatro deles malignos, únicos e maiores que 10 mm. Foi encontrado correlação significativa entre a determinação do tamanho do pólipo ao ultrassonografia e histopatológicos (r=0,44; p<0,001). A análise de Bland-Altman obteve uma superestimação do tamanho do pólipo ao US em 3,26 mm. A análise da curva da característica de operação do receptor entre as duas medidas obteve uma área sob a curva curva da característica de operação do receptor (AUC) de 0,77 (IC95% 0,74-0,81). Pólipos ao ultrassonografia maiores que 10 mm apresentaram razão de chance (OR) de 8,147 (IC95% 2,56-23,40) para presença de adenoma e malignidade, com razão de verossimilhança de 2,78. CONCLUSÕES: Há uma correlação positiva e acurácia diagnóstica apropriada entre o tamanho dos pólipos da vesícula biliar por ultrassonografia em comparação com os achados histopatológicos, com uma tendência de superestimar o tamanho em cerca de 3 mm. Pólipos maiores que 10 mm foram associados a adenoma e malignidade.

Apéndice cecal invertida: hallazgos en colonoscopía / Inverted cecal appendix: colonoscopy findings

Introducción. El apéndice cecal invertido, inversión apendicular o intususcepción apendicular, corresponde a una condición anatómica descrita en 1859. La primera operación de invaginación apendicular se realizó en 1890, y desde entonces se han descrito diferentes técnicas quirúrgicas y endoscópicas para el tratamiento de esta alteración. Casos clínicos. Se presentandos casos de pacientes a quienes se les indicó colonoscopia como parte de estudio de dolor abdominal y diarrea y se identificó una intususcepción apendicular completa y apendicitis y una inversión del muñón apendicular. Resultados. Mediante la colonoscopia se hizo el diagnóstico de apendicitis aguda en una de las pacientes, quien presentaba inversión apendicular completa tipo 5, que fue tratada con manejo farmacológico y seguimiento clínico. En la otra paciente hubo un hallazgo incidental de inversión del muñón apendicular tipo 3. Conclusiones. Durante la realización de estudios colonoscópicos, se debe tener en cuenta el diagnóstico de intususcepción apendicular o apéndice invertido, para evitar intervenciones erróneas, como polipectomías, que generen riesgo potencial en los pacientes.

Introduction. Inverted cecal appendix, appendicular inversion or appendicular intussusception, corresponds to an anatomical condition described in 1859. The first appendicular invagination operation was performed in 1890, and since then different surgical and endoscopic techniques have been described for its treatment. Clinical cases. We present two patients who underwent colonoscopy as part of the study of abdominal pain and diarrhea and in whom were identified a complete appendicular intussusception and appendicitis, and an inversion of the appendicular stump. Results. Through colonoscopy, the diagnosis of acute appendicitis was made in one of the patients, who presented type 5 complete appendicular inversion, which was treated with pharmacological management and clinical follow-up. In the other patient, the incidental finding of inversion of the appendicular stump type 3 was made. Conclusions. During colonoscopy, the diagnosis of appendicular intussusception or inverted appendix must be taken into account to avoid erroneous interventions such as polypectomies that generate potential risk in patients.

Pólipo Nasofaríngeo Primário: Apresentação Incomum / Primary Nasopharyngeal Polyp: Uncommon Presentation

Os pólipos inflamatórios não neoplásicos da nasofaringe são patologias raras e de consistência frágil, que normalmente são confundidos com outras lesões desta região. Entre essas, está o nasoangiofibroma, que possui consistência firme e sangra à manipulação. J.I.R.B., 17 anos, sexo masculino, estudante, com história de dor na faringe, com obstrução nasal noturna há 2 meses, associado à queixa de volume na garganta há 1 mês. À inspeção e oroscopia, encontrou-se uma volumosa lesão de aspecto polipoide, projetando-se da orofaringe. A ressonância magnética (RM) revelou lesão volumosa com componentes císticos, hiperintenso em T1 e hipointenso em T2, de aproximadamente 8,0 cm no seu maior diâmetro no corte sagital, que se estendia da nasofaringe até a orofaringe, chegando à região da epiglote. São descritos na literatura vários estudos relatando pólipos nasofaríngeos em felinos, mas apenas um estudo na literatura médica inglesa fala sobre as propriedades clínicas e histológicas dos pólipos inflamatórios primários da nasofaringe humana. Assim, o presente caso tem grande importância, principalmente pela sua raridade, local de acometimento do pólipo inflamatório benigno, bem como o tamanho da lesão. Na abordagem de massas naso e orofaríngeas em jovens e adultos, os pólipos inflamatórios primários fazem parte dos diagnósticos a serem considerados. Apesar do pequeno número de casos, as características radiológicas e patológicas dessa lesão devem ser lembradas, minimizando o risco de serem diagnosticados incorretamente.

Non-neoplastic inflammatory polyps of the nasopharynx are rare pathologies of fragile consistency, which are usually confused with other lesions of this region. Among these, the nasopharyngeal angiofibroma, which has firm consistency and bleeds to manipulation. J.I.R.B., 17 years old, male, student, with a history of pain pharynx, and nocturnal nasal obstruction for 2 months, associated with the complaint of volume in the throat for 1 month. Inspection and oroscopy, a polypoid lesion was found, protruding from the oropharynx. Magnetic resonance imaging (MRI) revealed a massive lesion with cystic, hyperintense components on T1-weighted images and hypointense at T2, approximately 8.0 cm in its largest diameter in the sagittal section, which was out of the nasopharynx to the oropharynx, reaching the epiglottis region. Several studies reporting nasopharyngeal polyps in felines have been described in the literature, but only one study in the English medical literature talks about the clinical and histological properties of the primary inflammatory polyps of the human nasopharynx. Thus, the present case is of great importance mainly, due to its rarity, site of involvement of benign inflammatory polyp, as well as the size of the lesion. In the approach of nasopharynx and oropharyngeal masses in young and adult, the primary inflammatory polyps are part of the diagnoses to be considered. Despite the small number of cases, the radiological and pathological characteristics of this lesion should be remembered, minimizing the risk of being misdiagnosed.

Incidence and characterization of colorectal adenomas in the area of influence of a specialized institution / Incidencia y caracterización de adenomas colorrectales en el área de influencia de una institución especializada

Abstract Aim: To locate and characterize colorectal adenomas endoscopically and histologically in a cohort of patients undergoing colonoscopy in Medellín, Colombia. Materials and methods: Descriptive cross-sectional study. We included patients older than 18 years who underwent colonoscopy between February and July 2020 at a specialized center in Medellín, Colombia. We determined the incidence of adenomas, their location in different segments of the colon, their endoscopic and histological characteristics, and cases of colorectal cancer (CRC) and high-grade dysplasia (HGD). Results: 992 colonoscopies were performed, finding colorectal polyps in 266 patients, of which 208 had adenomas. We resected 461 polyps, of which 336 were adenomas (72 %). The histological type with the highest representation was tubular (78 %). The location of adenomas was 37 % in the right colon, 25 % in the transverse colon, and 38 % in the left colon. CRC cases were nine per 1,000 patients, including advanced carcinoma and carcinoma in situ (HGD). Conclusions: Given the incidence of adenomas in the right and transverse colon, rectosigmoidoscopy is discouraged as a screening study for CRC. Tubular adenomas, sessile in appearance and tiny, predominated in the population studied. We recommend screening in the population over 40 years of age and the search for precursor lesions as strategies to reduce morbidity and mortality rates due to CRC.

Resumen Objetivo: localización y caracterización endoscópica e histológica de los adenomas colorrectales en una cohorte de pacientes sometidos a colonoscopia en Medellín, Colombia. Materiales y métodos: estudio descriptivo de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se determinó la incidencia de adenomas, su localización en los diferentes segmentos del colon, sus características endoscópicas e histológicas, así como también los casos de cáncer colorrectal (CCR) y displasia de alto grado. Resultados: se realizaron 992 colonoscopias y se encontraron pólipos colorrectales en 266 pacientes, de los cuales 208 tenían adenomas. En total se resecaron 461 pólipos, de los cuales 336 fueron adenomas (72 %). El tipo histológico con mayor representación fue el tubular (78 %). La localización de adenomas fue del 37 % en el colon derecho, 25 % en el transverso y 38 % en el colon izquierdo. La cantidad de casos de CCR fue de 9 por 1000 pacientes, que incluyen carcinoma avanzado y carcinoma in situ (DAG). Conclusiones: dada la incidencia de adenomas en el colon derecho y transverso, no se recomienda la rectosigmoidoscopia como estudio de tamizaje para CCR. En la población estudiada fueron predominantes los adenomas tubulares, de aspecto sésil y tamaño diminuto. Se recomienda el tamizaje en la población mayor de 40 años y la búsqueda de lesiones precursoras como estrategias para disminuir las tasas de morbimortalidad por CCR.

Analysis of patients undergoing colonoscopies and the importance of exam quality for colorectal cancer screening

Objective: To determine the impact of the quality of colonoscopy examination for colorectal cancer screening. Methods: Retrospective observational study ofmedical records from patients treated at the endoscopy and colonoscopy service of Hospital Universitário Evangélico Mackenzie (Curitiba, PR, Brazil) from January 2019 to January 2020. Results: The analysis was based on 337 medical records from patients with adenomas identified during colonoscopy, and 1,385 medical records from patients without adenomas. The estimated occurrence rate of diagnosis of adenoma during colonoscopy in the target population of the study was of 19.6%, with a 95% confidence interval ranging from 17.7 to 21.5%. Of the 337 patients with adenoma, 136 (40.4%) presented the advanced form. Statistical analysis indicated a significant association between the quality of colonoscopy preparation and test completion. Conclusion: The quality of colonoscopy images is a critical factor for colorectal cancer screening, as it leads to higher rates of adenoma detection and test completion. (AU)

Differential diagnosis of gallbladder polypoid lesions by micro-flow imaging / 南方医科大学学报

OBJECTIVE@#To explore the value of micro-flow imaging (MFI) in evaluating blood flow characteristics and differential diagnosis of gallbladder polypoid lesions.@*METHODS@#We retrospectively analyzed the clinical data and ultrasound images of 73 patients with gallbladder polypoid lesions, including 24 patients with pathologically confirmed neoplastic polyps (n=24) and 49 with non-neoplastic polyps (n=49). All the patients underwent conventional ultrasound, MFI and contrast enhanced ultrasound (CEUS) before cholecystectomy. The blood flow characteristics of the lesions in color Doppler flow imaging (CDFI) and MFI were compared, and the consistency of the findings by these two modalities with those of CEUS were evaluated by weighted Kappa consistency test. The diagnostic performance of MFI for gallbladder polypoid lesions was assessed.@*RESULTS@#There were significant differences between MFI and CDFI in the evaluation of blood flow characteristics of gallbladder polypoid lesions (χ2=37.684, P < 0.001). MFI showed better performance than CDFI in displaying the blood flow characteristics of the polyps. The consistency in the findings was 0.118 between CDFI and CEUS and 0.816 between MFI and CEUS. The sensitivity, specificity and accuracy of MFI in distinguishing neoplastic polyps from non-neoplastic polyps were 75.00%, 93.88% and 87.67%, respectively.@*CONCLUSION@#MFI has a good consistency with CEUS in displaying the blood flow characteristics of gallbladder polypoid lesions and can accurately distinguish neoplastic polyps from non-neoplastic polyps, thus providing new ultrasound diagnostic evidence to support clinical decisions on optimal treatments of gallbladder polypoid lesions.

Cáncer de vesícula biliar, una visión actual / Gallbladder cancer, a current view

Introducción. El diagnóstico de cáncer de vesícula biliar se realiza generalmente de forma incidental durante el estudio de las piezas quirúrgicas o cuando la enfermedad está avanzada y se expresa por su diseminación. Muy pocas veces se diagnostica de forma preoperatoria. Corresponde a la neoplasia más común de las vías biliares y su incidencia varía de acuerdo a la región geográfica. La región andina en Latinoamérica presenta una de las mayores incidencias a nivel mundial. Métodos. Se realizó una revisión narrativa de la literatura, para presentar una información actualizada en lo referente a los factores de riesgo (incluyendo las alteraciones genéticas y moleculares), al diagnóstico y al tratamiento de esta patología. Basados en los datos actuales, presentamos algunas recomendaciones dirigidas al diagnóstico temprano, que permita un manejo más adecuado de nuestros pacientes. Resultados. Se han implicado nuevos factores de riesgo relacionados con la etiología del cáncer de vesícula biliar, como la obesidad, factores genéticos y moleculares. A pesar de la disponibilidad de los métodos diagnósticos imagenológicos, no ha ocurrido una importante variación porcentual en cuanto al estadio al momento del diagnóstico. Conclusiones. El manejo quirúrgico del cáncer de vesícula biliar está indicado en los estadios más tempranos de la enfermedad y es importante evaluar las opciones terapéuticas en pacientes con enfermedad avanzada. Se considera de suma importancia el estudio anatomopatológico de la pieza quirúrgica y la revisión del informe por parte del cirujano.

Introduction. The diagnosis of gallbladder cancer is generally made incidentally during the study of the surgical pieces or when the disease is advanced and is expressed by its dissemination. It is rarely diagnosed preoperatively. It corresponds to the most common neoplasm of the bile ducts and its incidence varies according to the geographical region. The Andean region in Latin America presents one of the highest incidents worldwide. Methods. A narrative review of the literature was carried out to present updated information regarding risk factors (including genetic and molecular alterations), diagnosis and treatment of this pathology. Based on current data, we present some recommendations aimed at early diagnosis, which allows a more adequate management of our patients. Results. New risk factors related to the etiology of gallbladder cancer have been implicated, such as obesity, genetic and molecular factors. Despite the availability of diagnostic imaging methods, there has not been a significant percentage variation in terms of stage at diagnosis. Conclusions. Surgical management of gallbladder cancer is indicated in the earliest stages of the disease and it is important to evaluate therapeutic options in patients with advanced disease. The pathological study of the surgical piece and the review of the report by the surgeon are considered of utmost importance.

Atraso no diagnóstico do câncer: as razões podem começar na infância / Delay in cancer diagnosis: the reasons may start in childhood

A demora no diagnóstico do câncer atrasa o início do tratamento e tem impacto adverso no prognóstico do paciente. Embora o trauma infantil seja uma realidade comum na vida dos indivíduos, a ciência de sua ocorrência e consequências ainda são negligenciados em portadores de doenças crônicas. Estudos de nossa equipe e outros têm mostrado evidências das consequências do trauma infantil sobre aspectos emocionais, comportamentais e clinicopatológicos em pacientes com câncer. No entanto, até o momento, não há estudos que avaliaram a associação do trauma na infância com o atraso para o diagnóstico do câncer. O objetivo da presente pesquisa foi avaliar, pela primeira vez, a relação entre a ocorrência de trauma infantil e o tempo de demora para o diagnóstico da doença em um grupo de pacientes com câncer de cabeça e pescoço (CCP). Neste estudo transversal, 111 pacientes com câncer de cabeça e pescoço foram avaliados quanto aos fatores preditores para o tempo prolongado do paciente procurar atendimento e de sua trajetória no sistema de saúde até o diagnóstico da doença. O ponto de corte para avaliação do atraso para o diagnóstico foi de 3 meses, considerando até 3 meses como menor atraso e mais de 3 meses como maior atraso. Dados demográficos, clinicopatológicos e comportamentais foram extraídos dos prontuários dos pacientes. O Questionário sobre Trauma na Infância (QUESI) foi utilizado para avaliar a ocorrência de trauma infantil. Análises de regressão múltipla foram usadas para avaliar a associação das variáveis demográficas, comportamentais e clinicopatológicas, bem como da ocorrência de trauma na Infância com tempo de demora para o diagnóstico de câncer. Os resultados mostraram que o tempo médio de demora para os pacientes com CCP procurarem atendimento após perceber o primeiro sinal da doença foi de 129,50 dias, e o tempo médio de atraso entre o paciente procurar o primeiro serviço de saúde após perceber o tumor e receber o diagnóstico definitivo de câncer foi 196,43 dias. A ocorrência de abuso físico na infância foi uma variável independente para maior demora do paciente em procurar o primeiro atendimento após ter percebido o primeiro sintoma de câncer (OR = 3,22, IC = 1,020-10,183, p = 0,046). Pacientes que tinham o tumor localizado na laringe (OR = 13,5, IC = 2,645-69,355, p = 0,002) e tinham histórico de abuso emocional na infância (OR = 6,7, IC = 1,974-23,293, p = 0,002) eram mais propensos a terem um tempo maior que 3 meses entre a primeira consulta em um serviço de saúde e o recebimento do diagnóstico de câncer. Pacientes do sexo feminino (OR = 5,6, IC = 1,658-18,934, p = 0,006) e com o tumor localizado na laringe (OR = 11,2, IC = 2,204-56,987, p = 0,004), tiveram um maior atraso entre perceber o primeiro sintoma e ter o diagnóstico da doença. Em conjunto a fatores clinicopatológicos, o histórico de experiências traumáticas na infância pode ser preditivo para um maior atraso do paciente com câncer procurar os serviços de saúde e receber o diagnóstico. Os resultados do presente estudo devem estimular que a redução do trauma no período infantil seja considerada no desenvolvimento de estratégias para a prevenção secundária do câncer(AU)

Delay in the diagnosis of cancer retard the initiation of treatment and has an adverse impact on the patient's prognosis. Although childhood trauma is a common reality in the lives of individuals, the science of its occurrence and consequences are still neglected in patients with chronic diseases. Studies by our team and others have shown evidence of the consequences of childhood trauma on emotional, behavioral and clinicopathological aspects in cancer patients. However, to date, there are no studies that have evaluated the association of childhood trauma with delay in cancer diagnosis. The objective of the present research was to evaluate, for the first time, the relationship between the occurrence of childhood trauma and the delay time for the diagnosis of the disease in a group of patients with head and neck cancer (HNC). In this cross-sectional study, 111 patients with head and neck cancer were evaluated regarding predicting factors for the patient's prolonged time to seek care and their trajectory in the health system until the diagnosis of the disease. The cut-off point for evaluating the delay for diagnosis was 3 months, considering up to 3 months as the shortest delay and more than 3 months as the longest delay. Demographic, clinicopathological and behavioral data were extracted from the patients' records. The Childhood Trauma Questionnaire (CTQ) was used to assess the occurrence of childhood trauma. Multiple regression analyzes were used to assess the association of demographic, behavioral, and clinicopathological variables, as well as the occurrence of childhood trauma with time delay for the diagnosis of cancer. The results showed that the average delay for HNC patients to seek care after noticing the first sign of the disease was 129.50 days, and the average delay time between the patient seeking the first healthcare professional after noticing the tumor and receiving the definitive diagnosis of cancer was 196.43 days. The childhood physical abuse occurrence was an independent variable for the patient's longer delay in seeking first care after having noticed the first symptom of cancer (OR = 3.22, CI = 1.020-10.183, p = 0.046). Patients who had the tumor located in the larynx (OR = 13.5, CI = 2.645- 69.355, p = 0.002) and had a history of childhood emotional abuse (OR = 6.7, CI = 1.974-23.293, p = 0.002) were more likely to have a time greater than 3 months between the first consultation at a health service and receiving the diagnosis of cancer. Female patients (OR = 5.6, CI = 1.658-18.934, p = 0.006) and with the tumor located in the larynx (OR = 11.2, CI = 2.204-56.987, p = 0.004), had a longer delay between noticing the first symptom and being diagnosed with the disease. In conjunction with clinicopathological factors, the history of traumatic experiences in childhood may be predictive of a longer delay in the cancer patient seeking health services and receiving the diagnosis. The results of the present study should encourage the reduction of childhood trauma to be considered in the development of strategies for secondary cancer prevention(AU)

Morphological characteristics, classifications and difficulties in the use of diagnostic criteria for serrated lesions of the large intestine

Abstract: Introduction Colorectal carcinoma (CRC) is the most common gastrointestinal neoplasm in the world, accounting for 15% of cancer-related deaths. This condition is related to different molecular pathways, among them the recently described serrated pathway, whose characteristic entities, serrated lesions, have undergone important changes in their names and diagnostic criteria in the past thirty years. The multiplicity of denominations and criteria over the last years may be responsible for the low interobserver concordance (IOC) described in the literature. Objectives: The present study aims to describe the evolution in classification of serrated lesions, based on the last three publications of theWorld Health Organization (WHO) and the reproducibility of these criteria by pathologists, based on the evaluation of the IOC. Methods: A search was conducted in the PubMed, ResearchGate and Portal Capes databases, with the following terms: sessile serrated lesion; serrated lesions; serrated adenoma; interobserver concordance; andreproducibility.Articlespublished since 1990were researched. Results and Discussion: The classification of serrated lesions in the past thirty years showed different denominations and diagnostic criteria. The reproducibility and IOC of these criteria in the literature, based on the kappa coefficient, varied in most studies, from very poor to moderate. Conclusions: Interobserver concordance and the reproducibility of microscopic criteria may represent a limitation for the diagnosis andappropriatemanagementof these lesions. It is necessary to investigate diagnostic tools to improve the performance of the pathologist's evaluation, for better concordance, and, consequently, adequate diagnosis and treatment. (AU)
