Which statement is most accurate about PN indication in fistulas?

• A. PN is indicated for high-output fistulas defined as >500 mL/day.
• B. PN is indicated for all fistulas regardless of output.
• C. PN is never indicated for fistulas.
• D. PN is indicated only if fistula is in the small intestine.

Answer: (A)

When a fistula loses a lot of fluid and nutrients, the body’s nutritional needs can’t be met through oral or enteral feeding alone. This makes parenteral nutrition (intravenous nutrition) necessary to supply energy and protein and to offset losses, promoting healing and preventing malnutrition. The key point is the output level: once fistula drainage is high—typically defined as more than about 500 mL per day—enteral feeding often can’t meet the metabolic demands, so PN is indicated. For lower-output fistulas, enteral nutrition can usually be continued with careful management, and PN isn’t automatically needed. PN isn’t limited to fistulas in the small intestine, and it isn’t never indicated for fistulas.
