Management of Anorectal Malformations and Hirschsprung Disease.

Anorectal malformations (ARM) and Hirschsprung disease (HD) are managed with placement of normal intestine within the anal sphincter complex. Long-term complications specific to ARM include fistula remnants, recurrence, urinary reflux with associated chronic renal insufficiency, sexual dysfunction, and fertility difficulties. Complications specific to HD include enterocolitis, persistent or acquired aganglionosis, and internal sphincter achalasia. ARM and HD patients are both at risk of stricture, bowel dysfunction and incontinence, which can have a severe impact on quality of life. Bowel management strategies should be tailored to the patient's specific category of bowel dysfunction.
