Final answer:
A feeding tube that delivers nutrients directly into the stomach is known as a gastrostomy tube or G-tube. It is used for patients who require long-term nutritional support and can't eat by mouth. The esophagus is the tube leading to the stomach and has a valve to prevent stomach contents from re-entering it.
Step-by-step explanation:
A feeding tube that is placed in a patient's stomach to provide nutrients directly is called a gastrostomy tube or G-tube. The G-tube insertion is a medical procedure that is performed when a patient needs long-term nutritional support. Often, a patient who cannot eat by mouth, whether due to surgery, neurological conditions, or other health issues, needs this type of nutritional assistance to maintain adequate nutrient intake. The G-tube is inserted through a small incision in the abdomen and the stomach wall. It allows for the delivery of nutrients including liquids, medication, and food directly into the stomach, bypassing the mouth and esophagus.
When positioning the tube, the esophagus acts as the pathway leading down to the stomach. The esophagus is a long, narrow, tube-like digestive organ that carries food from the pharynx to the stomach through peristaltic movements. The lower end of the esophagus has a muscular valve called the lower esophageal sphincter which prevents the contents of the stomach from re-entering the esophagus. Overall, the G-tube helps achieve nutritional goals for patients who are unable to consume food orally and maintain their nutritional status adequately.
