Gastrointestinal Stent,A stent is a tube made of plastic or metal which is used for inserting into the lumen of a vessel to keep the space open in order to pass food or fluids during surgery and stenting is a term for placement of a stent. Stents are made up of unreal material that re built to be placed inside the body and rarely cause serious complexities to a patient as the insertion of any foreign body comes along with the certain risks of reaction. Stents also have slight chance from moving from its position causing discomfort. As stents are frequently used for patients who have coronary diseases and heart attack they are also used by gastroenterologists for treatment of cancer. A GI doctor makes the use of gastrointestinal stents majorly to open the bile ducts, colon, esophagus and the small bowel when those areas get blocked by cancerous tissues. The primary purpose of the gastrointestinal stent placement is to restore the patient’s natural capability of eating drinking ad digesting food through the gastrointestinal tract mainly as patients suffering from cancer face a difficulty to swallow, digest and pass stool at the time of treating cancer.

The adoption of stents gastrointestinal tract has broadened enormously. Placement of stent is used often for gastric cardiac cancer. Recently esophageal stents have been invented with the aim to reduce recurring dysphagia that happens due to overgrowth of tumor. The stents should be taken out within 4-8 weeks post placements in order to avoid the evolution of hyperplasia or granulation of tissue at the end of the stents. Expanding scientific studies prove that using metallic gastrointestinal stents are safe. These stents have shown great success rate and less complexity rates resulting in better quality of life for its patients.  In comparison to substitute therapies, they have been proven cost-effective.


Although stents are placed with high rates of success and safety, complexities may establish at the time of placing the stent which may be detected by the surgeon immediately post placement by the diagnostic imaging. Cancerous stenosis is more prone to complexities than favorable stenosis even though factors related to tumor are not always the reason behind failures of stents. The possibility of complexities developing can be accelerated by radiation therapy, chemotherapy and antiangiogenic therapy. For effective treatment planning the ability of the patient to go through radiotherapy and chemotherapy must be taken into consideration prior to the placement of the stent. Multiple Detector Computed Tomography gives inclusive information about the area the stent has been placed in and the complexities that could possibly occur.
