Resumen
Palliation of gastric outlet obstruction (GOO) and obstructive jaundice due to malignancy is a fundamental step in improving quality of life (QoL) and initiating or restarting systemic oncologic therapy in these patients. Endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting is still the primary treatment for malignant biliary obstruction (MBO), but it fails more frequently when GOO is concomitant. Poor quality studies are present in the medical literature on the application of endoscopic ultrasound (EUS) guided procedures among patients suffering from double obstruction, and few studies explore outcomes when endoscopy is performed during the same session or within a few days. Our aim was to systematically search the evidence supporting the use of EUS-guided procedures in this scenario in order to evaluate the best strategy for concomitant treatment of MBO and MGOO.
