Atresia ani (AA) is the congenital absence of anal opening where rectum is fully developed
Cause:Unknown but genetics seem to play a minor role.
Symptoms:A vet can make an obvious
visual diagnosis of anal atresia right after birth
The congenital abnormalities of the anus & rectum are fairely common in young ones ( Nixon, 1972, Dreyfuss & Tulleners,1989 & Ansari, 2005 )
Various surgical techniques have been used to correct AA in domestic animals ( Singh, 1989 & Jubb et al, 1993)
