The purpose of this study is to review the operative management and outcome of operation for Crohn's disease. The medical records of 17 patients who underwent operations due to Crohn's disease at Seoul National University Children's Hospital from January of 1988 to June of 2005 were reviewed and retrospective study was carried out. The male-to-female ratio was 1.8: 1. The median age at the onset of symptom and the time of diagnosis was 9 years 6 months and 11 years 6 months respectively. The median interval time from diagnosis to operation was 2 years and 1 month (0 month~8 years). Ileocolic or ileocecal region was the most common site of involvement. The indications of operation were intractable symptoms (8 cases) and obstruction or stricture (7 cases). The median postoperative hospitalized days were 14.4 days (8~35 days). Five patients (29%) experienced postoperative complications. Symptom free state or symptom relief was observed in 11 cases after surgery and 6 cases had wax and wane course of aggravation and improvement. In pediatric Crohn's disease patients who present with intractable symptoms despite medical treatment or develop surgical complications, symptom free state or symptom relief can be achieved by minimal resection of involved lesion.
