Background and Oblectives: We evaluated the success rate of endoscopically positioned nasojejunal feeding tubes and the intragastric countercurrent of contrast medium thereafter. Method: This retrospective observational study investigated patients who were admitted to a single intensive care unit and required endoscopic placement of a post-pyloric feeding tube between January 2010 and June 2016. The feeding tube was grasped with forceps via a transoral endoscope and inserted into the duodenum or jejunum. Thereafter, we assessed the position of the tube and the intragastric countercurrent using abdominal radiography with contrast medium. Results: The tube tip was inserted at the jejunum and the duodenal fourth portion in 55.8 and 33.6% of patients, respectively. The tip of the inserted tube had moved into the jejunum of 71.7% of patients by the following day. The countercurrent rate was significantly lower among patients with a tube inserted into the duodenal fourth portion or more distal than among those with tubes inserted more proximally (8.4 vs. 45.4%, p = 0.0022). Conclusions: The endoscopic insertion and positioning of a nasojejunal feeding tube seemed effective because the rate of tube insertion into the duodenal fourth portion or more distal was about 90%. The findings of intragastric countercurrents indicated that feeding tubes should be inserted into the duodenal fourth portion or beyond to prevent vomiting and the aspiration of enteral nutrients.

Transnasal endoscopic placement of nasoenteric tubes (NETs) has been demonstrated to be useful in the critical care setting, with limited data on its role in non–critically ill patients. The authors collected data on consecutive patients from a non–critical care setting undergoing transnasal endoscopic NET placement. All NETs were endoscopically placed using a standard over-the-guidewire technique, and positions were confirmed with fluoroscopy. Patients were monitored until the removal of NETs o...

BACKGROUND: There is an increasing demand for enteral feeding in intensive care unit (ICU) patients. However, gastroparesis is common, and jejunal placement with gastric decompression leads to delays in feeding. In an attempt to minimize delays, we describe our technique and results with transnasal endoscopic placement of double-lumen gastric aspiration, jejunal feeding tubes (DLFT). METHODS: Fifty-one consecutive ICU patients referred for nutrition support were studied; 29% had respiratory fail...

Context Gastrointestinal promotility agents may improve tolerance to enteral nutrition, reduce gastroesophageal reflux and pulmonary aspiration, and therefore have the potential to improve outcomes of critically ill patients. Objective To systematically review and critically appraise studies of promotility agents in the critical care setting.

Objective Critically ill patients often develop large gastric residual volumes during nasogastric feeding as a result of poor gastroduodenal motility. Nasojejunal feeding may decrease the severity of this complication. The aim of this study was to determine whether nasojejunal feeding improved toler
