What are the possible complications of gastrostomy tube replacement?
-
Commonly used by radiologists, Cope loop catheters (illustrated with a metal introducer stiffener) are easily placed into the stomach. However, their small lumina and small side holes predispose them to catheter occlusion.
-
Commonly used for surgical, endoscopic, and radiologic gastrostomy access, balloon catheters provide secure intraluminal retention and are simple to place and replace.
-
When gastrostomy tubes are dislodged, the sinus tract (top right) can be readily identified and recanalized for up to several days. With sinus tracts of this diameter, feeding tubes can often be reinserted directly. When tracts are narrower, angiographic catheters and wires are often used, and tract dilatation may be necessary for tube replacement.
-
Regarding tube-site infections, most catheter-related infections involve local cellulitis, as shown here, with erythema and tenderness. These infections frequently respond to local wound care and oral antibiotics.
