Balance studies in patients with intestinal resection: how long is enough?

Results from two independent metabolic balance studies in patients with ileal resection with or without a remaining colon were examined to assess the precision of the mineral, protein and fat balances obtained. 2. Low day-to-day variation in balances was found in patients with ileostomy/jejunostomy, irrespective of formula diet composition. In contrast, patients with a remaining colon showed considerable variation, with reliable cumulative balances often not reached for many weeks. 3. In conclusion, short-term cumulative balances can be performed with good precision in patients with ileostomy or jejunostomy.
