Which term describes the administration of a liquid directly into the stomach via a tube placed in the esophagus?

• A. Intraperitoneal tubing
• B. Stomach lavage
• C. Intragastric intubation
• D. Gastric gavage

Answer: (D)

Delivering a liquid directly into the stomach by threading a tube through the mouth and down the esophagus is called gastric gavage. This term specifically describes the act of administering substances into the stomach via an esophageal route, distinguishing it from procedures that involve other sites or purposes. Stomach lavage, for example, is washing out the stomach contents rather than dosing it. Intraperitoneal tubing goes into the abdominal cavity, not the stomach. Intragastric intubation refers to placing a tube into the stomach, but the term is broader and does not by itself specify that the liquid is being delivered through the esophagus for dosing. Gastric gavage is the standard term used when the goal is to administer a liquid directly to the stomach through an esophageal tube, a common technique in laboratory animals when oral dosing is necessary.
