Leakage: All G-tubes have some degree of leakage of stomach fluid around the tube onto the skin. Some G-tubes leak more than others, but leakage is considered a common G-tube complication, and most individuals will experience this complication at some point in time.
Leakage may be a sign of a mechanical problem with the G tube, such as not enough water in the ballon, an opening that has become too big, or a tube that no longer fits correctly. Usually, the leakage is minimal and easily manageable, but if severe, can cause significant irritation to the surrounding skin.
Clogging: G-tubes can become clogged due to build up of feeds or medications. Clogging can lead to the G-tube not working properly. This complication can be typically be prevented by providing water flushes before and after feeds and as well as before and after medication administration. Your CF care team can provide tips for preventing clogging or make suggestions for different declogging methods.
