Naso-jejunal feeding in allogeneic bone marrow transplant recipients: results of a pilot study.

Patients undergoing allogeneic bone marrow transplants (BMT) are often malnourished prior to commencing the procedure. They face intensive treatment with often marked nutritional consequences. There is no consensus on the optimal nutritional management of these patients. Elective parenteral nutrition (PN), beginning pre-transplant irrespective of the patients nutritional status, or the use of "salvage" PN, beginning during the post-transplant period if the patient fails to maintain nutritional status with oral diet, have been used. Enteral nutrition may benefit the patient by maintaining nutritional support throughout the transplant period, avoiding the complications and expense of PN and possibly, by using specific diets, protecting the gastrointestinal tract from the effects of chemoradiation. However, naso-gastric feeding during a transplant is not without risks, including the safe insertion of a tube in patients with mucositis and pan-cytopenias, tube displacement by vomiting and aspiration from gastro-oesophageal reflux. An alternative approach is to use naso-jejunal (NJ) feeding tubes which are associated with less risk of loss due to vomiting and less risk of aspiration. We report a pilot study of 15 allogeneic BMT patients who had elective NJ feeding initiated before conditioning therapy irrespective of perceived nutritional compromise. This was well tolerated and feasible with a motivated nutritional team.
