Endoluminal stenting is performed using an endoscope, which consists of a narrow tube with a light, camera and other instruments. For an endoluminal stent being placed in the esophagus, bile duct or pancreas, the endoscope is placed down the throat. For an endoluminal stent in the colon or bowel, the endoscope is placed through the anus. Fluoroscopy, which is a live imaging technology, may also be used to further guide endoscopic stent placement.
After the endoscope is inserted, a small guide wire is inserted through the blocked area and then the stent is placed. Sometimes, the blocked area is dilated before stent placement.
