Which statement about endoscopy is true?

Which statement about endoscopy is true?

• A. It is good for morphological diagnosis
• B. It cannot biopsy
• C. It cannot inspect the esophageal lumen
• D. It cannot perform dilation

Answer: (A)

Endoscopy provides a direct view of the esophageal mucosa, so you can assess structural and inflammatory changes visually. Beyond just looking, you can take targeted tissue samples with biopsy forceps, and those samples are examined histologically to confirm the nature of lesions, inflammation, metaplasia, or cancer. That combination—visual assessment plus tissue diagnosis—makes it very strong for morphological diagnosis. In addition, endoscopy can also inspect the lumen for abnormalities and, when needed, perform dilation with balloons or bougies in the same session. So the statement that endoscopy is good for morphological diagnosis is true, while the other statements overlook its biopsy capability, lumen inspection, and dilation potential.
