RESUMO

BACKGROUND AND AIMS: There is conflicting evidence regarding the impact of hypothetical cumulative fatigue after performing too many endoscopic procedures on both polyp and adenoma detection rates (PDR, and ADR, respectively). The aim of this study is to evaluate the effect of successive endoscopic procedures on PDR and ADR. METHODS: A retrospective cross-sectional study was undertaken among consecutive patients on whom colonoscopy and/or esophagogastroduodenoscopy were performed between January 2012 and August 2014. Data regarding polyp and adenoma detection, cecal intubation, and bowel cleansing quality as well as demographical data of subjects were extracted. Endoscopic procedures were classified according to the time slots of the procedures throughout the endoscopy session in three groups: from the 1st to 4th endoscopy study (round 1), from the 5th to the 8th study (round 2), above the 9th study (round 3). We compared PDR and ADR among rounds. RESULTS: Overall, 3388 patients were enrolled. Median age was 50 years (range 18-95) and 52.39% were female. There was a significant difference in terms of PDR among rounds (36.83%, 41.24%, and 43.38%, respectively, p = 0.007) and a non-significant numerical difference when ADR was compared (23.2%, 25.71%, and 26.78%, p = 0.07). On multivariate analysis, ADR was significantly associated with age (odds ratio [OR] 1.02 [1.01-1.03]), and male sex (OR 1.64 [1.38-1.94]). CONCLUSION: Theoretical endoscopist's fatigue due to cumulative performance of endoscopies does not diminish colonoscopy quality. Both PDR and ADR seem to improve after endoscopist's cumulative rounds of performed endoscopies. This could be due to a "warm-up" effect.

RESUMO

BACKGROUND: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant genodermatosis characterized by benign growth of the hair follicles, the presence of pulmonary cysts, spontaneous pneumothorax, and bilateral renal tumors that are usually hybrid oncocytic or multifocal chromophobe renal cell carcinoma. The diagnosis is confirmed by the presence of a pathogenic variant in the tumor suppressor folliculin (FLCN) gene mapped at 17p11.2. Although the dermatological lesions typical of BHDS are benign and only cause aesthetic concerns, and the pulmonary manifestations are controllable, the greater tendency of patients with this syndrome to present benign or malignant renal tumors, often bilateral and multifocal, makes the diagnosis of this syndrome important for the prognosis of the patients. The objective was to report the case of a patient with BHDS, without pulmonary manifestations and with hyperplastic polyposis of the gastrointestinal tract, and to perform a literature review. CASE PRESENTATION: A 60-year-old man complained of abdominal pain and diarrhoea for 2 months. Physical examination was normal except for the presence of normochromic papules in the frontal region of the face associated with hyperkeratotic and hyperchromic papules in the dorsal region. The excisional biopsies of the skin lesions indicated trichodiscomas. Esophagogastroduodenoscopy, enteroscopy, and colonoscopy showed the presence of hyperplastic polyps in the stomach, duodenum, jejunum, colon, and rectum. Computed tomography (CT) and magnetic resonance imaging (MRI) of the abdomen revealed multiple expansive solid lesions in both kidneys, with necrotic and calcified areas. Renal magnetic resonance angiography also showed a solid lesion in the right kidney measuring 5 cm in diameter and another solid lesion in the left kidney measuring 8 cm in diameter, both suggestive of renal angiomyolipoma. CT scans of the skull, chest, and temporal bones were normal. The genetic study revealed the presence of a variant of FLCN in the intron 13. CONCLUSIONS: To the best of our knowledge, this is the first reported case of BHDS with the simultaneous finding of gastrointestinal hyperplastic polyposis, which may represent a possible phenotypic expression of this syndrome that has not yet been described.

RESUMO

INTRODUCCIÓN: Aunque los tumores neuroendocrinos rectales son neoplasias poco frecuentes, su incidencia está aumentando en las tres últimas décadas. El objetivo de este trabajo es el estudio del comportamiento de dichos tumores basándonos en sus variables clínicas, diagnósticas, terapéuticas y anatomopatológicas en un hospital terciario. MÉTODO: Estudio retrospectivo de los tumores neuroendocrinos rectales desde el año 2000 hasta el año 2017 en nuestro hospital. Se realizó una búsqueda informatizada en el programa SNOMED del servicio de anatomía patológica, empleando los criterios «tumor neuroendocrino¼ y «tumor carcinoide¼. RESULTADOS: Se hallaron 16 pacientes con tumor neuroendocrino ano-rectal. El 75% eran varones. La mediana de edad fue de 53 años (rango: 34-83). El diagnóstico fue incidental en el 62,5%. El tratamiento fue endoscópico en 13 (81%) pacientes y quirúrgico en 3 (19%). El 75% de las lesiones fueron T1. El 68,7% de los tumores presentaban un grado de agresividad G1. La media de seguimiento fue de 29 meses; no hubo recidivas. Durante el seguimiento fallecieron 3 (18,5%) pacientes, todos ellos con tumor G3 metastásico, y la supervivencia media fue de 8 meses. CONCLUSIONES: Los tumores neuroendocrinos rectales son cada vez más frecuentes y presentan unos patrones variables, cuyo pronóstico dependerá de su agresividad histológica. El aumento de su incidencia puede deberse a una mayor concienciación de la existencia de estos tumores, a las campañas de cribado del cáncer colorrectal, al aumento del número de colonoscopias realizadas y a la generalización de los estudios histológicos con marcadores neuroendocrinos. BACKGROUND: Although rectal neuroendocrine tumours are rare neoplasms, their incidence is increasing in the last three decades. The objective of this work is to study the behaviour of these tumours based on their clinical, diagnostic, therapeutic, and pathological variables in a tertiary hospital. METHOD: Retrospective study of rectal neuroendocrine tumours from 2000 to 2017 in our hospital. A computerized search was performed in the SNOMED program of the pathological anatomy service, using the criteria "neuroendocrine tumour" and "carcinoid tumour". RESULTS: We found 16 patients with ano-rectal neuroendocrine tumour; 75% were male. The median age was 53 years (range: 34-83). The diagnosis was incidental in 62.5%, with endoscopic treatment in 13 patients (81%) and surgical treatment in 3 (19%). 75% of the lesions were T1. 68.7% of the tumours showed a degree of G1 aggression. The mean follow-up was 29 months; no recurrences. During follow-up, three patients died (18.5%), all of them with metastatic G3 tumour and the mean survival was 8 months. CONCLUSIONS: The rectal neuroendocrine tumours are increasingly frequent and present variable patterns, whose prognosis will depend on their histological aggressiveness. The increase incidence may be due to a greater awareness of the existence of these tumours, to colorectal cancer screening, to the increase in the number of colonoscopies performed and to the generalization of histological studies with neuroendocrine markers.

RESUMO

BACKGROUND: Inflammatory fibroid polyp (IFP) is a very rare benign condition in children that can occur throughout the gastrointestinal tract. It is characterized as a polypoid lesion originating in the submucosa, composed of connective tissue and eosinophilic infiltrate. It is most common in the stomach and in adults between the fifth and seventh decades of life. Its occurrence is unusual in the duodenum. CASE SUMMARY: One case of duodenal IFP was described and the literature is reviewed with emphasis on the clinical and pathological features of IFP in children. A case of an IFP in the duodenum of a 13-year-old girl, who presented with abdominal pain, weight loss, vomiting, and constipation. The patient underwent exploratory laparotomy; a stenosing tumor of the third duodenal portion was found. The affected segment was resected and an end-to-end anastomosis between the duodenum and jejunum segment was performed. Immunohistochemically, actin and CD34 were positive, Ki67 was positive in <1% of cells, and the proteins CD117 and S100 were negative. CONCLUSION: To our best of our knowledge, this is the fourth report of IFP in adolescents, the first in a female's duodenum.

RESUMO

Pólipos colorretais são pequenas protrusões da mucosa colônica e do reto, sendo a sua grande maioria de potencial maligno baixo (como os adenomas tubulares com displasia de baixo grau) ou nulo (como os pólipos hiperplásicos). Os pólipos que contêm potencial maligno ­ os adenomas ­ são a parte inicial da cascata de carcinogênese de 95% das neoplasias malignas colorretais e podem ser diagnosticados e removidos através da colonoscopia. Esta guia apresenta informação que orienta a conduta para casos de pólipos colorretais no contexto da Atenção Primária à Saúde, incluindo: classificação dos pólipos colorretais, avaliação dos pólipos colorretais, seguimento das lesões pré-malignas, manejo dos pólipos colorretais, colonoscopia - procedimento e cuidados, rastreamento e vigilância de câncer colorretal, encaminhamento para serviço especializado.

RESUMO

Abstract Background Inflammatory cloacogenic polyp is a very rare kind of benign polyp which occurs in the anal transitional zone and lower rectum. These polyps arise in association with various conditions (e.g., internal hemorrhoids, diverticulosis, colorectal tumors, and Crohn's disease) in which mucosal injury is the underlying pathogenic mechanism. Case report A 24-year-old male patient applied to emergency department with bloody defecation for a month. A polyp that is 1.5 cm in size had been observed at rectum and anal verge junction during colonoscopy, pathological diagnosis was inflammatory cloacogenic polyp. Thereupon, colonoscopic polypectomy was performed as the malignant transformation possibility. Conclusion Polyps of the anorectal junction with inflammatory appearance might be inflammatory cloacogenic polyps with malignant transformation potential that must be treated by endoscopic removal or surgery and followed up routinely with colonoscopic surveillance.


Resumo Experiência Pólipos cloacogênicos inflamatórios constituem um tipo muito raro de pólipo benigno, com ocorrência na zona de transição anal e reto baixo. Esses pólipos surgem em associação com diversos distúrbios (p. ex., hemorroidas internas, diverticulose, tumores colorretais, e doença de Crohn) nos quais a lesão à mucosa é o mecanismo patogênico subjacente. Relato de caso Paciente, gênero masculino, 24 anos, compareceu ao serviço de emergência com defecação sanguinolenta com duração de um mês. Durante a colonoscopia, foi observado um pólipo medindo 1,5 cm de diâmetro no reto e na junção da borda anal; foi estabelecido um diagnóstico patológico de pólipo cloacogênico inflamatório. Subsequentemente, foi realizada polipectomia colonoscópica, diante do potencial de transformação maligna. Conclusão Pólipos da junção anorretal com aspecto inflamatório podem ser pólipos cloacogênicos inflamatórios com potencial para transformação maligna, devendo ser tratados por remoção endoscópica ou cirúrgica e monitorados periodicamente com vigilância colonoscópica.
