Crohn's disease can involve any part of the gastrointestinal tract. Although good conservative treatment is given as soon as possible, most patients with this disease will eventually require surgery. We encountered a case of Crohn's disease associated with anemia which we treated with laparoscopic-assisted ileectomy. The postoperative course was satisfactory. The most important characteristic of Crohn's disease, fat wrapping and extending over the serosal surface toward the antimesenteric border, was observed in the ileum, distinguishing the disease and pinpointing the lesion accurately. This surgical method has an advantage over open surgery in that the recovery time is shorter and incisions are smaller, allowing easier surgery in the future, shortening the patient's hospital stay, and improving the patient's quality of life.
