title: Acquired ileal atresia and spontaneous reconstitution of intestinal continuity in a premature infant with necrotizing enterocolitis.
abstract: An 849-g (26-week gestation) premature infant had pneumoperitoneum on the 20th day of life after having normal stools and accepting partial enteric alimentation. Percutaneous penrose drainage had to be performed on 2 consecutive days at 2 different sites (right lower quadrant, left lower quadrant), at which time she stabilized. Eleven days later, she started to pass stool, and oral feeding was begun (1 to 2 mL every 4 hours). Enteral intake could not be advanced because of repeated bouts of abdominal distension, despite having regular bowel motions. Gastrointestinal contrast radiographic investigation suggested a stricture of the ileum. At laparotomy (at age 2 months) ileal atresia with a "V"-shaped defect in the mesentery was found. Surprisingly, intestinal continuity was established via an ileoileal fistula. After resection and anastomosis, she recovered fully. Mesenteric and enteric vascular ischemia (necrotizing enterocolitis) produced acquired ileal atresia-a rare occurrence. More rare is the reestablishment of intestinal continuity by fistulization.
