Endoscopische bypass bij obstructie van de maaguitgang

A new, minimally invasive technique has recently been developed that creates a gastrojejunostomy by placing a stent that connects the stomach to the jejunum. This procedure is a promising alternative treatment method for palliation of malignant gastric outlet obstruction. At present, these patients are often treated with surgical gastrojejunostomy, which is associated with significant morbidity, such as gastroparesis. A less invasive alternative is endoscopic placement of a duodenal stent, but this has the disadvantage that it is frequently associated with stent dysfunction caused by the tumour growing into the stent. In theory, endoscopic gastrojejunostomy combines the best of both techniques as it is a minimally invasive procedure associated with low morbidity and quick clinical effect, but without the complications caused by gastroparesis or stent obstruction. Prospective clinical trials are needed to compare the effectiveness and safety of the endoscopic bypass with the traditional treatment methods.
