Gastric Outlet Obstruction (GOO) refers to a medical condition characterized by a blockage or obstruction that prevents the normal flow of stomach contents from entering the small intestine. The obstruction typically occurs at the junction between the stomach and the duodenum, known as the pylorus.
The most common cause of gastric outlet obstruction is the presence of a physical barrier, such as a tumor or scar tissue, that obstructs the passage of food from the stomach into the intestines. Other less common causes include stomach ulcers, inflammation, or structural abnormalities.
Symptoms of gastric outlet obstruction may include severe abdominal pain, nausea, vomiting, bloating, feelings of fullness, and inability to eat or drink. The condition can lead to malnutrition, dehydration, and weight loss if left untreated.
Diagnosis of gastric outlet obstruction typically includes a physical examination, medical history review, and imaging tests such as X-rays, ultrasound, CT scans, or endoscopy. Once diagnosed, treatment options for gastric outlet obstruction may include medication to reduce stomach acid production, placement of a stent or balloon to open the blocked area, surgical removal of the obstruction, or other procedures to alleviate the obstruction and restore normal digestive flow.
In summary, gastric outlet obstruction is a condition characterized by a blockage in the passage of food from the stomach to the small intestine. It is typically caused by physical barriers and can result in severe symptoms and complications if not properly diagnosed and treated.
