Atresia ani
Also known as: Imperforate anus · Anal atresia · Atresia ani et recti · Fehlbildung des Afters · Anusatresie · …
Overview
What it is
Atresia ani is a congenital birth defect of the lower digestive tract where the anal opening is either completely closed or entirely missing. Because the normal exit path for stool is blocked, waste cannot leave the body, leading to a dangerous buildup in the intestines. This condition is present at birth and requires prompt medical attention to restore normal digestive function.
How it presents
Symptoms usually become noticeable shortly after birth or when the puppy transitions to solid food. Owners will typically observe a bloated abdomen, painful straining to defecate without producing stool, and vomiting.
Treatment
The condition is treatable through immediate surgical reconstruction, which is a major, one-time procedure, though some dogs may experience lifelong complications like incontinence. The estimated cost for this surgery and initial recovery care ranges from €1,500 to €5,000.
