Endoscopic stenting is a medical procedure by which a stent, a hollow device designed to prevent constriction or collapse of a tubular organ, is inserted by endoscopy. They are usually inserted when a disease process has led to narrowing or obstruction of the organ in question, such as the esophagus or the colon.

There are various types of endoscopic stents: plastic stents, uncovered self-expandable metallic stents, partially covered self-expandable metallic stents, and fully covered self-expandable metallic stents.{{cite journal | vauthors = Lam R, Muniraj T | title = Fully covered metal biliary stents: A review of the literature | journal = World Journal of Gastroenterology | volume = 27 | issue = 38 | pages = 6357–6373 | date = October 2021 | pmid = 34720527 | doi = 10.3748/wjg.v27.i38.6357 | pmc = 8517778 | doi-access = free }} Self-expandable metallic stents "play an important role in the management of malignant obstructing lesions in the gastrointestinal tract."{{cite journal | vauthors = McLoughlin MT, Byrne MF | title = Endoscopic stenting: where are we now and where can we go? | journal = World Journal of Gastroenterology | volume = 14 | issue = 24 | pages = 3798–3803 | date = June 2008 | pmid = 18609702 | pmc = 2721435 | doi = 10.3748/wjg.14.3798 | doi-access = free }}

A stent may be inserted into the common bile duct during an endoscopic retrograde cholangiopancreatography, especially if gallstone removal is deemed too risky.{{Cite web | url=https://www.keckmedicine.org/treatments/pancreatic-surgery/ |title = Pancreatic, Gallbladder and Biliary Surgery | work = Keck Medicine | publisher = University of Southern California (USC) }}
