In which condition is a double-balloon enteroscopy particularly useful?

• A. Esophageal stricture treatment
• B. Small bowel lesions inaccessible by regular endoscopic techniques
• C. Colorectal cancer detection
• D. Pyloric stenosis treatment

Answer: (B)

A double-balloon enteroscopy is particularly useful for accessing and visualizing the small intestine, especially when it comes to lesions that are not reachable with standard endoscopic techniques. This specialized procedure utilizes two balloons on the endoscope that can inflate and deflate to advance the scope through the loops of the small bowel, allowing for thorough examination and potential biopsy of lesions. The small intestine often presents challenges for direct visualization due to its length and convoluted structure; standard upper and lower endoscopy may not reach these areas effectively. Thus, when small bowel lesions are suspected, such as tumors, polyps, or bleeding sites, double-balloon enteroscopy is an invaluable tool. In contrast, the other options listed pertain to conditions where double-balloon enteroscopy would not be the first-line approach or may not be applicable at all. Esophageal strictures typically require alternative methods for dilation or stenting that do not involve accessing the small intestine. Colorectal cancer detection relies on colonoscopy techniques, which are designed to visualize the colon specifically. Pyloric stenosis treatment generally involves surgical intervention rather than endoscopic techniques. Each of these conditions presents its own challenges and treatment protocols that do not align with the specific advantages offered by double-balloon enter
