Sixty of 127 prednisone-dependent patients with ulcerative colitis who underwent colectomy and endorectal ileal pull-through with ileal reservoir and subsequent laparotomy with ileostomy closure (254 operations) during a 4-year period developed 95 episodes of intestinal obstruction during the early post-operative period. Acute ileus due to steroid withdrawal caused symptoms of intestinal obstruction in 43 patients (76 episodes), whereas true mechanical small-bowel obstruction occurred in only 17 patients (19 episodes). Symptoms of both conditions were similar; however, hypoactive bowel sounds, acute onset of emotional depression, no evidence of obstruction on radiologic contrast stomatogram or enema, and prompt relief of symptoms within 4 hours after intravenous administration of hydrocortisone acetate distinguished acute steroid withdrawal. Since ileus from acute steroid withdrawal occurred four times as frequently as mechanical small-bowel obstruction, prompt recognition and treatment should appreciably reduce postoperative morbidity and hospital costs.
