Prótesis endoluminal autoexpandible en una oclusión aguda por tumor del colon izquierdo

endoscopic use of self-expanding prostheses is described in two patients with acute mechanical occlusion of left colon, treated in the emergence service of our center allowing us to improve the hydroelectric symptomatic status of patients, as well as the colon preparation. this latter avoided an emergence surgery and decompression colostomy; surgery was programmed for the subsequent five ones. anatomical-pathological results confirmed the presence of large seal-ring colon's adenocarcinomas in the descendent colon in a patient, and in the sigmoid colon in another one.
