摘要
Gastric outlet obstruction(GOO)is a clinical syndrome secondary to luminal obstruction at the level of the stomach and/or duodenum.GOO can be caused by either benign or malignant etiologies,often resulting in early satiety,nausea,vomiting and poor oral intake.GOO is associated with decreased quality of life and has been shown to significantly impact survival in patients with advanced malignancies.Traditional treatment options for GOO can be broadly divided into surgical[surgical gastrojejunostomy(GJ)]and endoscopic interventions(dilation and/or placement of luminal self-expanding metal stents).While surgical GJ has been shown to provide a more lasting relief of symptoms when compared to luminal stenting,it has also been associated with a higher rate of adverse events.Furthermore,many patients with advanced metastatic disease are not good surgical candidates.More recently,endoscopic ultrasound(EUS)-guided GJ has emerged as a potential alternative to traditional surgical and endoscopic approaches.This review focuses on the new advances and technical aspects of EUS-GJ and clinical outcomes in the management of both benign and malignant disease.
