Enteral stenting is a non-surgical outpatient procedure that helps to relieve an obstruction that is caused by an uncontrolled tumor in the digestive tract which includes the upper digestive (GI) tract (esophagus stomach, esophagus, and the upper part of the small intestine, also known as duodenum) and the lower GI tract (colon and the rectum).
A Stent is a flexible, self-expanding, hollow tube made of plastic or metal which is utilized to keep an area open within the tract of the stomach which is affected by a malignant late-stage tumor. Intraoral stents are employed to allow patients eating, or in preparation for surgery. For many patients with cancer in their esophagus or stomach, also known as duodenum or duodenum, the region may be narrowed, and the area will need to be expanded so that food can be able to pass through.
In cases of advanced pancreatic, esophageal, or colorectal cancers doctors might recommend a stent if chemotherapy, surgery, and radiation aren’t the best options. For those with colon cancer who are scheduled for surgery to remove the tumor Stents are a good option to ease bowel cleanse in the preparation for surgery. This will improve the outcomes of surgical procedures.
Doctors can also utilize enteral stenting to treat benign conditions like fistulas and leaks bleeding varices, and tightening, or narrowing of the GI tract.
How to Prepare for Enteral Stent Placement
If the procedure is carried out through the mouth it is advised not to consume food or drink after midnight the night before the procedure.
If the procedure is performed through the rectum you might be given an enema to cleanse the colon from the blockage region. You may also be directed to undergo oral bowel preparation if it is appropriate to do so.
Your physician will inform you whether or when it is time to alter or stop the medications you are taking. Since you’ll be under sedation it is necessary for someone to take you home following the procedure.
What to Expect
Stents are inserted in an upper endoscopy or colonoscopy. If you are placing a stent in the lower GI tract (esophagus stomach, esophagus, or duodenum) the endoscope is placed via the throat. A mouth guard is put in place to safeguard your gums and teeth. The throat can be numbed by sprays to ease your gag reflex.
You’ll lie on your left side and be given an IV line of sedation to ease your mind and cause you to feel sleepy. The doctor will then use balloons to increase the size of the duodenum or esophagus when necessary, and then insert the stent so that the stomach remains open.
In order to place the stent inside the colon, an endoscope is inserted into the anus into your colon and rectum. The air is pumped through the endoscope to increase the volume of the colon to make it more visible and for the doctor to be able to put the stent.
The procedure typically takes between 15 and 45 minutes. Following the procedure, you will be transported to the recovery room as the sedative is fading off. There may be some discomforts that are temporary like sore throat (if you underwent the procedure via an Upper Endoscopy) and the sensation of gas or bloating or cramps.
It is necessary to follow the prescribed diet for the first few days after the procedure. Your physician will give you these guidelines. They will also discuss any unusual negative side effects that might be experienced and a strategy to deal with the issues.
