Balloon catheter dilatation of focal intestinal strictures following necrotizing enterocolitis.

Dilatation with a balloon catheter was successfully employed for 9 focal intestinal strictures which occurred in 5 infants following necrotizing enterocolitis. Eight of the 9 strictures were located in defunctionalized colon distal to an enterostomy; no infant had clinical intestinal obstruction. Because the dilatation achieved distal patency, subsequent closure of the enterostomy was accomplished without a formal laparotomy. The balloon dilatation technique may be valuable in the management of focal strictures that are not causing clinical intestinal obstruction.
