ABSTRACT
Objetivo: Estudiar las características clínicas y endoscópicas de la proctitis crónica hemorrágica por radioterapia en el Instituto Nacional de Enfermedades Neoplásicas del Perú. Materiales y métodos: Estudio descriptivo, retrospectivo y longitudinal, con una población de 588 pacientes con esta patología, en el periodo 2011-2013, de donde se seleccionaron 114 pacientes por muestreo probabilístico aleatorizado. Se usó la estadística descriptiva e inferencial para el análisis de las variables cualitativas y cuantitativas. Resultados: La investigación encontró como principales resultados, un periodo de latencia de 439,96 días; la severidad de rectorragia clínica fue grado II y III en el 86,84%, la hemoglobina media fue de 11,63 gr/dl, los hallazgos endoscópicos fueron severidad moderada en el 58,77%, extensión solo rectal en el 92,11%, friabilidad leve del 43,86%, compromiso menor del 33% de la superficie rectal en el 71,93% y una longitud media de 7,28 cm. Los hallazgos inflamatorios fueron de cicatrices en el 0,88%, erosiones del 0,88%, de úlceras del 7%, de fístula del 0,88% y del 3,51% de estenosis rectales, el tratamiento de argón plasma coagulación (APC) único o combinado se ofreció en el 96% de los casos. Conclusiones: La proctitis crónica hemorrágica por radioterapia fue una complicación importante de la radioterapia pélvica, con hallazgos clínicos y endoscópicos característicos.
Objective: To study the clinical and endoscopic features of chronic hemorrhagic proctitis by radiotherapy in the National Institute of Neoplastic Diseases of Peru. Materials and methods: The study was descriptive, retrospective and longitudinal, with a population of 588 patients with this pathology, in the period 2011-2013, from which 114 patients were selected by randomized probabilistic sampling. Descriptive and inferential statistics were used for the analysis of qualitative and quantitative variables. Results: The main results were a latency period of 439.96 days; the severity of clinical rectal bleeding was grade 2 and 3 in 86.84%, the mean hemoglobin in chronic hemorrhagic proctitis by radiotherapy was 11.63 g / dl, the endoscopic findings were moderate severity in 58.77%, extension rectal only in 92.11%, slight friability of 43.86%, compromise less than 33% of the rectal surface in 71.93% and an average length of 7.28 cm. The inflammatory findings were 0.88% scars, erosions of 0.88%, ulcers of 7%, fistula of 0.88% and 3.51% of rectal stenosis, single or combined argon plasma coagulation (APC) treatment was offered in 96% of cases. Conclusion: Chronic hemorrhagic proctitis is an important complication of pelvic radiotherapy, with characteristic clinical and endoscopic findings.

The aim of our study was to describe the radiologic findings of extensive acute lung injury associated with limited thoracic irradiation. Limited thoracic irradiation occasionally results in acute lung injury. In this condition, chest radiograph shows diffuse ground-glass appearance in both lungs and thin-section CT scans show diffuse bilateral ground-glass attenuation with traction bronchiectasis, interlobular septal thickening and intralobular smooth linear opacities.
