Early vs delayed home parenteral nutrition in short bowel

What is known

• A recent 18-year single-centre CD cohort argues early nutritional intervention is needed to prevent consequences of severe malnutrition but explicitly calls for further studies on HPN impact. ¹
• In that cohort SBS was the leading HPN indication (58.7%); 41.3% were weaned and 26% achieved nutritional autonomy, but no early-vs-delayed survival contrast was reported. ¹
• Older UK/Ireland and cross-national registries report HPN survival and mortality (including treatment-related deaths) but are descriptive, not timing comparisons. ^2,3

What is unknown / caveats

• No study in the retrieved set stratifies survival by timing of HPN initiation
• Evidence is registry/retrospective cohort. No RCT or comparative design on this question
• HPN carries competing mortality from catheter sepsis, liver failure and metabolic complications, which any timing analysis would have to account for
• The timing-versus-survival question is simply not addressed by the indexed literature retrieved.
