La estenosis colorrectal benigna hace referencia a una condición anatómica caracterizada por una disminución del diámetro de la luz intestinal distal a la válvula ileocecal, ocasionando una serie de signos y síntomas de tipo obstructivo. Es una entidad poco frecuente, secundaria en la gran mayoría de veces a la realización de anastomosis intestinales al nivel descrito. El objetivo de esta investigación fue determinar la utilidad del stent colónico en estenosis secundaria a patología colorrectal no neoplásica.  Métodos.  Estudio descriptivo de una cohorte de pacientes que desarrolló estenosis colorrectal de origen benigna confirmada por colonoscopía, en 3 hospitales de alta complejidad de la ciudad de Medellín, Colombia, entre los años 2007 y 2021.  Resultados.  Se incluyeron 34 pacientes con diagnóstico de estenosis colorrectal de origen benigno, manejados con stents metálicos autoexpandibles. La mediana de seguimiento fue de 19 meses y se obtuvo éxito clínico en el 73,5 % de los casos. La tasa de complicación fue del 41,2 %, dada principalmente por reobstrucción y migración del stent, y en menor medida por perforación secundaria a la colocación del dispositivo.  Conclusión.  Los stents metálicos autoexpandibles representan una opción terapéutica en pacientes con obstrucción colorrectal, con altas tasas de mejoría clínica en pacientes con patología estenosante no maligna. Cuando la derivación por medio de estoma no es una opción, este tipo de dispositivos están asociados a altas tasas de éxito clínico y mejoría de la calidad de vida de los pacientes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Introduction. Benign colorectal stenosis refers to an anatomical condition characterized by a decrease in the diameter of the intestinal lumen distal to the ileocecal valve, which might cause a series of obstructive signs and symptoms. It is a rare entity, caused in the vast majority of cases due to intestinal anastomosis at the described level. The purpose of this study is to determine the performance of colonic stents in the management of non-malignant colorectal strictures.  Methods. Descriptive study of a cohort of patients who developed a benign colorectal stenosis confirmed by colonoscopy in three high-complexity hospitals in the city of Medellín, Colombia, between 2007 and 2021.  Results.  Thirty-four patients diagnosed with benign colorectal stenosis managed with self-expanding metal stents were included in the study. Median follow-up was 19 months, obtaining clinical success in 73.5% of cases, with a complication rate of 41.2%, mainly due to reobstruction and migration of the stent, and to a lesser extent due to perforation secondary to device placement.  Conclusion. Self-expanding metallic stents represent a therapeutic option in patients with colorectal obstruction caused by non-malignant stenosing pathology. When diversion through a stoma is not an option, this type of device is associated with high rates of clinical success and improvement in the patients&#8217; quality of life.]]></p></abstract>
