Total parenteral nutrition and complete bowel rest in the management of Crohn's disease.

Abstract

The role of parenteral nutrition with complete bowel rest in the management of active Crohn's disease was evaluated retrospectively in 100 patients who were otherwise refractory to conventional medical management. Ninety patients received complete nutrient replacement and 10 received protein-sparing therapy. In 77 patients, a clinical remission was achieved. Analysis of subgroups revealed that the remission rate was equivalent in patients with subacute bowel obstruction (76%), inflammatory mass (82%), and otherwise uncomplicated severe active disease (89%). However, those patients with fistulae responded less well (63%). The location of the intestinal involvement with the disease did not influence the remission rate (73% in those with small bowel disease only and 78% in those with combined small and large bowel disease). All six patients with only large bowel involvement achieved a remission. In 81% of those patients with a remission, no corticosteroids were given, or the dose prior to TPN was maintained. The serum albumin improved significantly (p less than 0.001) from 3.2 +/- 0.1 to 3.6 +/- 0.1 g/dl with total parenteral nutrition, but there was no significant effect on the hematocrit (p greater than 0.5). The percentage of patients still in remission after 3 months and 1 yr of follow-up was 75 to 79 and 58 to 61%, respectively, in the three nonfistulous groups, and 46 and 36%, respectively, in those with fistulous disease. Thus total parenteral nutrition with complete bowel rest appears to be an effective therapeutic modality in the primary management of complicated Crohn's disease.
