“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. Furthermore, the construction of a mucosa-lined tube with valve-like control at the gastric end tends to prevent the regurgitation of the irritating gastric contents. This allows periodic intubation and frees the patient from the irritation of a constant indwelling tube.”
