Which technique is used to study the upper portion of the small intestine?

• A. colonoscopy
• B. sigmoidoscopy
• C. umbilical endoscopy
• D. enteroscopy

Answer: (D)

The technique used to study the upper portion of the small intestine is enteroscopy. Enteroscopy is specifically designed to allow visual examination of the small intestine, which is critical for diagnosing conditions such as Crohn's disease, tumors, or vascular malformations. It usually involves the use of specialized endoscopes, such as a balloon-assisted enteroscope, which can reach deeper sections of the small bowel. In contrast, colonoscopy focuses on the examination of the large intestine (colon) and the distal part of the small intestine, while sigmoidoscopy targets the sigmoid colon and rectum specifically. Umbilical endoscopy is not a standard term used in medical practice and generally would not be associated with the study of the small intestine, making enteroscopy the appropriate and accurate choice for studying the upper portion of the small intestine.
