AB An  anal  fissure,  or  fissure-in-ano,  is  one  of  the  most  common  anal  disorders  seen  by  physicians.  It  is  a  linear  tear  or  crack  that  extends  into  the  anoderm  from  the  mucocutaneous  junction  to  the  dentate  line  (Figure  67-1).  An  anal  fissure  usually  results  from  the  passage  of  hard  stool  that  traumatizes  and  tears  the  anoderm.  Frequent  bowel  movements  with  diarrhea  can  cause  similar  “cracks”  that  eventually  result  in  fissures.  Anal  fissures  are  often  seen  in  infants,  but  primarily  are  a  condition  of  young  and  middle-aged  adults.1–3  It  is  the  most  common  cause  of  acute  onset  painful  rectal  bleeding  in  adults  and  in  the  first  year  of  life.
