AB Intestinal  atresia  (from  Greek  meaning  “non-perforated”)  denotes  a  complete  obliteration  of  the  intestinal  lumen  and  is  commonly  used  to  describe  congenital  conditions.  Intestinal  webs,  which  are  thin  intraluminal  diaphragms  that  are  lined  with  mucosa,  are  a  form  of  atresia.  Webs  may  be  stretched  out  to  give  the  appearance  of  a  windsock.  Stenosis  is  a  narrowing  of  the  intestinal  lumen.  Intestinal  atresias  and  webs  may  be  subclassified  based  on  anatomical  location.  They  may  occur  in  the  esophagus,  stomach,  duodenum,  jejunum,  ileum,  colon,  or  anus.1
