Being male, having a complete obstruction and having a distal location of the tumor in the colon were considered to be risk factors, as were inexperienced endoscopists, use of small caliber stents, use of steel stents, and dilation of the stenosis prior to stenting.
Ser varón, tener una obstrucción completa y una localización tumoral distal en el colon son considerados factores de riesgo. Respecto a la técnica, la inexperiencia del endoscopista, utilizar prótesis de pequeño calibre o de acero y dilatar la estenosis antes de colocar la prótesis conllevan una mayor tasa de complicaciones.
