It is important to discuss this with your doctor but PEG tubes can last for months or years. Tubes can break down or become clogged over extended periods of time therefore, they might need to be replaced. Your doctor can easily remove or replace a tube without sedatives or anaesthesia, although your doctor might opt to use sedation and endoscopy in some cases. Your doctor will remove the tube and either insert a new tube or let the opening close if no replacement is needed. PEG sites close quickly once the tube is removed, so accidental dislodgement requires immediate attention.
