Enteral iron and quality of life after ileocolic resection

What is known

• A randomised controlled trial of ferrous fumarate corrected iron-deficiency indices (serum ferritin, iron retention) in ileostomy patients, but the study was small and mostly ulcerative colitis, not post-resection Crohn's. ¹
• Systematic review found oral iron effective for short periods but limited by intolerance/discontinuation in up to 21%, with no established diagnostic or treatment criteria. ²
• Iron deficiency's quality-of-life impact (fatigue, delayed recovery) is described in review and consensus text, not measured against an enteral-iron QoL endpoint. ^2,3

What is unknown / caveats

• No retrieved trial measured quality of life as an endpoint
• Controlled enteral-iron data are from a small 1982 ileostomy cohort, predominantly ulcerative colitis, not ileocolic-resection Crohn's
• Oral iron may enhance intestinal inflammation in colitis models, and IV iron is favoured in active disease
• Your framing is largely correct: the enteral-iron evidence here is small, dated, and does not report a blinded quality-of-life outcome after ileocolic resection.
