As a temporary gastrostomy, the Witzel or the Stamm procedure is used frequently and is easily performed. A permanent type of gastrostomy, such as the Janeway and its variations, is best adapted to patients in whom it is essential to have an opening into the stomach for a prolonged period of time. Under these circumstances, the gastric mucosa must be anchored to the skin to ensure long-term patency of the opening.
