Abstract
Metal stent insertion to relieve malignant gastroduodenal obstruction is an effective alternative to surgery, but there are some problems associated with existing metal stents for malignant gastroduodenal obstruction. Common complications of covered and uncovered stents are migration and obstruction, respectively. To date, there are several practice-improved stents, such as partially covered, double-layer, three-layer, and individualized stents designed according to the shape and size of the Gastric Outlet Obstruction (GOO). Choosing the most appropriate type of stent is arduous and should be done mainly in relation to the morphological aspects of the stricture. In general, the stent is implanted by a Through-The-Endoscope (TTS) method, but certain types of stent can only be implanted by a peroral route. After adequate training, endoscopic gastroduodenal stent insertion is a reproducible, simple, safe, and costeffective procedure, with high technical and clinical success rates.
