[Techniques of percutaneous endoscopy gastrostomy--a comparison of methods].

In the clinical praxis there are many seriously ill patients who are unwilling, unable or not allowed to eat. These patients must be fed either parenterally or enterally via permanent nasoenteral gavage. A third method for artificial feeding is the percutaneous endoscopic gastrostomy. In the last time this method was established and different modifications are given. They can be divided into two main techniques: 1. the transoral pull-string method 2. the "Introducer" technique Advantages and disadvantages of the methods used will be discussed and an own modification is presented. By this new modification it is possible to introduce macroluminal Pezzercatheters as gastrostomy. The macroluminal gastric fistula allows the usage of viscous or crushed food. Special or imported instruments or sets are unnecessary.
