What term describes the small bowel series using gastrointestinal intubation?

• A. Enteroclysis
• B. Duodenal examination
• C. Fiber optics
• D. Endoscopy

Answer: (A)

The correct term for a small bowel series that involves gastrointestinal intubation is enteroclysis. This procedure is specifically designed to deliver contrast material directly into the small intestine through a tube that is inserted into the duodenum. The use of enteroclysis allows for a more thorough examination of the small bowel's anatomy and functional aspects, enabling better visualization of abnormalities like obstructions or tumors compared to a traditional small bowel series which may only include oral contrast administration.

Other options such as duodenal examination, fiber optics, and endoscopy refer to different diagnostic techniques. A duodenal examination typically focuses on imaging the duodenum specifically rather than the entire small bowel. Fiber optics is a general term that can apply to various endoscopic techniques but does not specifically refer to the method of gastrointestinal intubation used to visualize the small bowel. Endoscopy refers to the broader practice of examining the interior of a hollow organ with an endoscope and can be used to look at various parts of the gastrointestinal tract, but again, it does not specifically imply the use of enteroclysis. Thus, enteroclysis is the precise term for the described procedure in your question.
