A 538 gm female baby, gestational age 25 weeks 5 days, was born on July 5, 1982. She was transferred to the authors' hospital because of low birth-weight. Two days after birth, abdominal distension was noted. Abdominal X-ray films and enema using contrast material revealed an intestinal obstruction. On laparotomy, ileal volvulus and peritonitis due to ileal perforation were noted. Ileostomy was performed. After the operation, mechanical ventilation was done and continued. Extubation was possible on 87 days after birth. On the 5 days after operation, naso-gastric tube-feeding was started and the volume was gradually increased. On the 165 days after birth, her body weight became 1.0kg. Unfortunately, however, the patient died due to respiratory disorder before closure of ileostomy.
