RESUMO
Recent international publications remark the association about carcinoma of the colon and cholelithiasis. These two entities with similar geographical distribution can be seen frequently in the modern western societies, being the cause as aetiological factors the low content in dietetics fiber. Different studies about the carcinoma of the colon and cholelithiasis pathogenesis had lead the possibility that the abnormal degradation of bile acids for the colonic bacterias, could be responsible of each one of these illness. The exposition of colonic mucosa to products of degradation of bile acids, specially secondary bile acids, may play a role in the etiopathogenic of colon carcinoma. It was analysed 135 patients with colon carcinoma or adenomatosis polyps, 42 with cholelithiasis or cholecystectomized for the same cause (31.1%), although in the control group, only 2(5%) had cholelithiasis. The female predominated the group of colon carcinoma and cholelithiasis, as well as cholecystectomized for that cause. The most frequent associated pathology was the diverticulosis.

RESUMO
El método de toma citológica por punción aspirativa se ha usado con éxito en las lesiones accesibles con agujas corrientes. Las lesiones del tractus digestivo son de más dificil acceso, lo que ha hecho que no conozcamos antecedentes ninguno en la literatura con este método. Hemos ideado, desde 1978 la forma de tomar la muestra através de los aparatos de fibra óptica en las exploraciones endoscópicas, adaptando a un tubo de polietileno de tamaño suficiente para sobrepasar el colonoscopio, en su extremo distal un pequeño trócar y en su extremo proximal a la parte ajustable del trócar para adaptar la jeringuilla que va a efectuar la aspiración. Se pasa a través del canal de la biopsia del colonoscopio, puncionando la lesión y extrayendo por aspiración el material para el extendido citológico que se hace en ese momento fijándose para su posterior coloración y observacion microscópica. Se presenta el resultado de la citología aspirativa en 100 casos de lesiones tumorales o elevadas detectadas en el curso de las colonoscopias haciendo un estudio comparativo con la citología exfoliativa y la biopsia de los mismos casos, de forma de poder comparar el índice de positividad diagnóstica entre los tres métodos. Se estudiaron 77 adenocarciocomas, 9 adenomas vellosos, 6 polipos, 5 lesiones elevadas en el curso de colitis ulcerativa idiopática de larga evolución y 3 lesiones inflamatorias. La citología aspirativa tuvo mayor positividad que la exfoliativa complementando los fallos de los estudios biópsicos en los casos de neoplasis malignas con gran componente necrótico. Se resalta la utilida del método de la citología aspirativa por su sencillez, inocuidad y seguridad diagnóstica

The method of cytologic samples by aspirative punction was successfully used in lesions that are accessible with common needles. The digestive tract's lesions are of more difficult access, and that is the reason why we do not known any antecedent with this method in the literature. Since 1978 we have thought about some way of taking the sample by fiberoptic devices in endoscopic explorations, adjusting to a polyethylene tube of suitable measure, as to exceed the colonoscopy, in the distal extreme, a little trocar and on its proximal extreme the adjustable part of the trocar for the adaptation of the syringe that makes the aspiration. It crosses through the biopsy channel of the colonoscope, puncturing the lesion and extracting the material by aspiration to prepare the cytologic smear, and fixing it for its further coloration and microscopic observation. We present the result of the aspirative cytology in 100 cases of tumoral or elevated lesions detected in the course of a colonoscopy, performing a comparative study with the exfoliative cytology and biopsy of the same cases, to compare the diagnostic positivity index between all the tree methods. We have studied 77 adenocarcinomas, 9 villous adenomas or polyps, 5 elevated lesions in long-evolution idiopathic ulcerative colitis and 3 inflammatory lesions. The aspirative cytology had greater positivity than the exfoliative one, complementing the judgement of biopsy studies in cases of malign neoplasia with great necrotic component. It must be underlined the utility of aspirative cytology method due to its simplicity, innocuousness and diagnostic security.

RESUMO
Colon Polyps constitute are one of the most frequent causes of rectal bleeding in infancy. The advent of endoscopic polypectomy through colonoscopy has resulted very useful in their treatment. From 1979 to 1984, 73 polypectomies were performed in 64 patients with colonic polyps, between 2 and 14 years old, 26 girls and 38 boys. 103 polyps were resected, 71 pedunculated and 32 sessiles. The most frequent location was the recto-sigmoid (85.6%), with 14.4% situated above it. 55.7% of the removed polyps were more than 1 cm., juvenile histologic type predominating (90%). No complication was observed either during or after this procedure. It is demonstrated that, endoscopic polypectomy in children is a safe, simple and effective method which avoids complications that may or surgery might produce.
