Abstract
A hollow, rigid guide tube has a bend nearer to one end than the opposite end. The bent end of the guide tube is inserted through an animal'"'"'s mouth and esophagus, and into its stomach. The bent end is pressed against the interior of the animal'"'"'s stomach by manipulating the opposite end which extends out of the animal'"'"'s mouth. A needle is pushed through the animal'"'"'s skin and into the stomach end of the guide tube. A fiber is passed through the needle and into and through the whole guide tube. The fiber then extends from outside the animal'"'"'s abdomen through the stomach wall, through the esophagus and out the animal'"'"'s mouth. The guide tube and needle are removed and a gastrostomy tube is fastened to the mouth end of the fiber and is pulled into the stomach sidewall in the conventional manner. The guide tube preferably has an outwardly flared surface at one end and has an annular disk attached near the opposite end of the tube.
