title: The effect of perioperative blood transfusion on recurrence after primary operation for Crohn's disease.
abstract: The effect of perioperative blood transfusion on recurrence after primary operation was retrospectively studied in a group of 104 patients with Crohn's disease. Patients who had minor procedures like strictureplasty, segmental small-bowel resection, and operation for perianal fistula were excluded. Patients who had more extensive surgery were selected, to have an approximately equal distribution of blood transfusion in the different subgroups. Sixty-six female and 45 male patients were included; 65 patients had perioperative blood transfusion and 39 did not. Irrespective of blood transfusion it was confirmed that patients with small-bowel localization have a better prognosis than patients with combined or colonic localization. Patients who had resection of a specimen of less than 30 cm or more than 70 cm had a worse prognosis than the others. The reason for this observation is unclear. Except for patients with colonic localization only, blood transfusion was about equally distributed among patients with ileocaecal localization (19 of 36) and patients with ileal disease (17 of 34). Perioperative blood transfusion had no effect on disease recurrence, either for the whole group of transfused patients or for any of the subgroups, apart from those with colonic localization only. They had a significantly lower recurrence, as diagnosed before 60 months of follow-up. This is ascribed to the fact that these patients had large colonic resection with a lower chance of having active recurrent disease. In conclusion, we could not confirm the protective effects of blood transfusion on recurrence of Crohn's disease, as observed by others.
