Brief summary
Malignant gastric outlet obstruction (GOO) results from the mechanical obstruction of the duodenum or distal stomach from an underlying cancer. The aim of this study is to compare the clinical outcomes between surgical gastrojejunostomy and EUS-guided gastrojejunostomy in patients with malignant gastric outlet obstruction.
Detailed description
Malignant gastric outlet obstruction (GOO) results from the mechanical obstruction of the duodenum or distal stomach from an underlying cancer. The consequences of GOO are abdominal pain, nausea, vomiting, anorexia, inability to maintain an oral diet and weight loss, with associated poor quality of life and inability to continue with cancer therapy. The aim of this study is to compare the clinical outcomes between surgical gastrojejunostomy and EUS-guided gastrojejunostomy in patients with malignant gastric outlet obstruction.
Interventions
AXIOS lumen-apposing metal stent will be used to create a gastrojejunostomy under EUS guidance.
A surgical gastrojejunostomy will be created via laparoscopic or robotic techniques (preferred) or open technique (if these methods fail), as clinically appropriate.
