Created using ChatSlide

Gastric Outlet Obstruction (GOO) involves impaired gastric emptying, often due to mechanical or functional blockages at the pylorus or duodenum. Key causes include peptic ulcer disease and caustic injuries leading to strictures, while congenital stenosis and mucosal diaphragms are less common. Recognising GOO requires a structured approach to interpret clinical findings and understand the underlying mechanisms, ensuring effective resuscitation and resolution of the obstruction.
