Definitive surgical correction of Hirschsprung disease, which is usu. performed at 6Ð12 months of age; involves resection of distal aganglionic bowel mucosa. Normal bowel is pulled into anal canal with delayed anastomosis to anal verge. Associated complications (more frequent than with Duhamel procedure) include rectal prolapse (25%), rectal stenosis (20%Ð25%), enterocolitis (20%Ð25%), and constipation/anastomotic leakage (5%Ð10%).
