Clinically, it's simply referred to as a gastric tube, which is relatively short and easy to insert. The passage from the nose to the esophagus to the stomach is quite straightforward without much bending, and it is usually inserted blindly by nurses.
Other tubes are more complex, such as nasoduodenal tubes, nasojejunal tubes, and jejunostomy tubes, all of which must be inserted into the intestines. A person's intestines are twisted and winding, similar to a maze, making blind insertion extremely difficult. Generally, these are placed during a surgical procedure by a surgeon or inserted with the aid of a digestive endoscope under direct visualization.
For patients who have undergone gastrointestinal surgery, leaving such tubes during surgery is a routine risk consideration by surgeons, taking into account the possibility of postoperative anastomotic leaks, as a precaution.
