What is the term for the radiologic examination of the small intestines using a tube for barium sulfate injection?

• A. Endoscopy
• B. Fluoroscopy
• C. Enteroclysis
• D. Laparoscopy

Answer: (C)

The term for the radiologic examination of the small intestines using a tube for barium sulfate injection is enteroclysis. This procedure involves the direct introduction of barium sulfate into the small intestine, enabling detailed visualization of the intestinal mucosa through fluoroscopic imaging. The use of barium provides contrast that highlights the small intestines, making it easier for radiologists to identify any abnormalities such as tumors, Crohn’s disease, or strictures.

Endoscopy refers generally to visual examination of internal structures using an endoscope, but it typically involves direct visualization rather than radiologic imaging. Fluoroscopy is a technique that provides real-time moving images of the interior of the body, but it doesn't specifically refer to the method involving barium sulfate injection through a tube. Laparoscopy, on the other hand, is a surgical procedure involving small incisions and a camera, focused on surgical interventions rather than imaging alone. Thus, enteroclysis specifically denotes the procedure being asked about, distinguishing it from the other methods listed.
