Percutaneous gastrostomy. A clinical and experimental study.

Fluoroscopic percutaneous gastrostomy for the purpose of nutrition was performed in 28 patients with the aid of a specially designed gastrostomy set. No major complications were reported. Exchange to Foley catheter was performed after 7 days and could be used without complications for the patients' remaining life span. In order to evaluate the formation of a gastrocutaneous tract, an experimental study with the same instruments as in clinical practice was performed in 13 rabbits. Within one week a gastrocutaneous tract was formed, which was possible to dilate for insertion of a balloon catheter of larger size. The described procedure is a simple and time-saving method for a percutaneous gastrostomy in debilitated patients with dysphagia.
