Table 1 Definitions of outcomes
Outcome | Definition |
|---|---|
Reinsertion | The insertion of an endoscope or tube in the nose/mouth and esophagus for (re) placement of the feeding tube. |
Repositioning | Reinsertion of the EM transmitting stylet when the tube has not left the stomach/esophagus. |
Dislodgement | Any displacement of the feeding tube making continuation of tube feeding unsafe (e.g. because it is delivered into the stomach in the presence of gastroparesis) or impossible (e.g. when the tube has been removed from the patient), confirmed on the Cortrak® monitor or abdominal radiograph. |
Blockage | The inability to pass tube feeding through the tube whilst it is still in the correct position. |
Successful tube placement | The tip of the feeding tube positioned beyond D2 [preferably near the ligament of Treitz (i.e. duodenojejunal flexure)] or in the efferent jejunal limb (in the presence of a gastro- or duodenoenterostomy) on the Cortrak® monitor or abdominal radiograph (depending on the placement method) followed by successful enteral feeding, without signs of feeding entering the stomach. |
Duration of tube stay | The number of days that the feeding tube was in its correct position. |
