Comparison of Foley catheter as a replacement gastrostomy tube with commercial replacement gastrostomy tube: a prospective randomized trial.
Percutaneous endoscopic gastrostomy (PEG) provides a non-surgical alternative to long-term enteral feeding. The gastrostomy tube, however, may deteriorate, malfunction, or be accidentally expelled, requiring replacement. A commercial gastrostomy tube is commonly used for replacement. However, a commercial replacement gastrostomy tube is many times more expensive than a Foley catheter, and the two have never been compared. We compared the efficacy and safety of an all-silicone Foley catheter used as a replacement feeding gastrostomy tube with the effectiveness of a commercial replacement gastrostomy tube in 46 patients undergoing long-term enteral feedings per gastrostomy. Twenty-four patients were randomized to the Foley group and 22 patients to the commercial replacement gastrostomy tube group. The Foley catheter functioned well without need for replacement in 16 (66%) patients for 27.4 +/- 14.8 (mean +/- SD) weeks; the commercial replacement gastrostomy tube functioned in 13 (59%) patients for 24.5 +/- 13.6 weeks (p > 0.05, NS). The Foley catheter needed to be replaced because of malfunction in 8 (34%) patients and the commercial replacement gastrostomy tube in 9 (41%) patients after 21.6 +/- 11.5 weeks and 19.3 +/- 9.3 weeks, respectively (p > 0.05, NS). Neither the Foley catheter nor the commercial replacement gastrostomy tube migrated; this was the most striking finding, in contrast to case reports in the literature. Our data suggest that the Foley catheter can be safely used as a replacement gastrostomy tube; it is considerably cheaper than the commercial replacement gastrostomy tube, and its efficacy and complication rates are similar to those of the commercial replacement gastrostomy tube.
