Percutaneous endoscopic gastrostomy (PEG) is a medical procedure used to place a feeding tube directly into the stomach through the abdominal wall. This is typically done for patients who cannot eat by mouth due to various conditions, such as stroke, neurological disorders, or cancer. The procedure is performed using an endoscope, which allows doctors to see inside the stomach and guide the tube placement. The PEG tube provides a way to deliver nutrition, fluids, and medications directly to the stomach, ensuring that patients receive the necessary support for their health. It is a minimally invasive procedure, often performed under local anesthesia, and can be done in a hospital or outpatient setting.
