After induction of general anesthesia and intubation, a gastric tube was inserted using the Tumguide system. After the gastric tube was advanced approximately 50 cm, light from the Tumguide was confirmed emanating below the left rib. The gastric tube was ultimately advanced another 20 cm and fixed in place. A postoperative chest radiograph confirmed the gastric tube was positioned inside the stomach; however, it was withdrawn approximately 10 cm and resecured. Although there are various methods, like radiography, for confirming appropriate positioning of a gastric tube, the insertion process is blind. The Tumguide uses light with high biopermeability for illumination, which enables the gastric tube tip to be indirectly viewed as it is moved into position. Although this system has not gained wide usage, we feel this is a useful device that merits further exploration.<\/jats:p>","DOI":"10.2344\/23-0052","type":"journal-article","created":{"date-parts":[[2025,6,9]],"date-time":"2025-06-09T05:08:16Z","timestamp":1749445696000},"page":"100-103","source":"Crossref","is-referenced-by-count":0,"title":["Experience Using a New Gastric Tube Tip Localization System (Tumguide)"],"prefix":"10.2344","volume":"72","author":[{"given":"Toru","family":"Oshikiri","sequence":"first","affiliation":[{"name":"Department of Dental Anesthesiology, The Nippon Dental University, School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yui","family":"Akiho","sequence":"additional","affiliation":[{"name":"Anesthesiology and Resuscitation, The Nippon Dental University Graduate School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mio","family":"Hanyu","sequence":"additional","affiliation":[{"name":"Department of Dental Anesthesiology, The Nippon Dental University, School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hajime","family":"Hara","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, The Nippon Dental University, School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichiro","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, The Nippon Dental University, School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Oohashi","sequence":"additional","affiliation":[{"name":"Department of Dental Anesthesiology, The Nippon Dental University, School of Life Dentistry at Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1191","reference":[{"key":"i1878-7177-72-2-100-b01","series-title":"Intensive Care Med","first-page":"406","article-title":"Radiographic detection of intrabronchial malpositions of nasogastric tubes and subsequent complications in intensive care unit patients","volume":"23","author":"Bankier AA","year":"1997","unstructured":"Bankier AA,\nWiesmayr MN,\nHenk C, et al.
