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. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; 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%, &lt;i&gt;p&lt;\/i&gt; = 0.0022). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; 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.<\/jats:p>","DOI":"10.1159\/000502676","type":"journal-article","created":{"date-parts":[[2019,9,4]],"date-time":"2019-09-04T21:00:35Z","timestamp":1567630835000},"page":"163-167","source":"Crossref","is-referenced-by-count":6,"title":["Endoscopic Insertion of Nasojejunal Feeding Tube at Bedside for Critically Ill Patients: Relationship between Tube Position and Intragastric Countercurrent of Contrast Medium"],"prefix":"10.1159","volume":"75","author":[{"given":"Hiroomi","family":"Tatsumi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Akatsuka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Kazuma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoichi","family":"Katayama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuya","family":"Goto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Monma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichiro","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiki","family":"Masuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2019,9,4]]},"container-title":["Annals of Nutrition and Metabolism"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/502676","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/502676","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:54:00Z","timestamp":1745423640000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000502676"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2019,12,13]]},"published-print":{"date-parts":[[2019,12,17]]}},"URL":"https:\/\/doi.org\/10.1159\/000502676","archive":["Portico"],"relation":{},"ISSN":["0250-6807","1421-9697"],"issn-type":[{"value":"0250-6807","type":"print"},{"value":"1421-9697","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019]]}}}
