Which post-operative screening is recommended at 2 years after surgery?

• A. Bone density scan
• B. B12 level every 2 years
• C. Vitamin A level
• D. Urinalysis

Answer: (A)

Two years after this type of surgery, bone health becomes a key long-term concern because nutrient absorption changes can lead to bone loss over time. A bone density scan, often done with a DEXA exam, directly measures bone mineral density and can detect osteopenia or osteoporosis early. This makes it the best choice for screening at this interval, since it targets the specific complication most likely to emerge after malabsorptive or weight‑loss procedures.

Other options aren’t as well aligned with this specific screening need at two years. B12 levels are important, but they’re typically checked more frequently than every two years due to the ongoing risk of deficiency. Vitamin A levels and urinalysis aren’t standard or targeted screenings at this point for monitoring post-op bone health.
