Final answer:
To view the fundus of the stomach in fluoroscopy, the patient might be positioned in the oblique or left lateral decubitus position for clear imaging. The fundus stores undigested food and gases and is essential for digesting activities. For detailed imaging, an endoscopic ultrasound may be used.
Step-by-step explanation:
To view the fundus of the stomach in fluoroscopy, the patient's body must be positioned to ensure that the fundus, the uppermost section of the stomach, is appropriately visualized. During an upper GI tract examination with fluoroscopy, such as when checking for peptic ulcers or observing gastric emptying, it is common to use a position that allows the fundus to be filled with barium, providing a clear image. While lying on their back (supine position) can offer a view, patients are often asked to rotate into an oblique or left lateral decubitus position to bring the fundus into clearer view, allowing gravitational forces to coat and delineate its surface on imaging.
The fundus of the stomach stores undigested food and gases released during chemical digestion. The inspection of the fundus is essential to assess crucial digestive process activities, including the continued effect of salivary amylase and the activation of lingual lipase. Furthermore, the fundus can be examined via endoscopic procedures, such as an endoscopic ultrasound, where a camera or ultrasound probe is inserted through the esophagus to visualize the internal regions of the stomach.
