AB Esophageal  diverticula  are  unusual  but  interesting  abnormalities  that  can  develop  in  any  part  of  the  esophagus.  The  most  common  esophageal  diverticulum  occurs  in  the  cervical  region  and  is  known  as  a  Zenker  diverticulum.  An  esophageal  diverticulum  may  also  occur  in  the  midesophagus  near  the  pulmonary  hilum  or  as  an  epiphrenic  diverticulum  near  the  gastroesophageal  junction.  There  are  two  categories  of  esophageal  diverticula—pulsion  and  traction.  Each  has  a  distinct  etiology.  Pulsion  diverticula  are  the  most  common  type  in  the  United  States,  and  develop  as  a  consequence  of  a  motility  abnormality  in  the  esophagus  distal  to  the  site  of  the  diverticulum.1  They  are  false  diverticula  since  they  are  not  composed  of  the  entire  wall  of  the  esophagus,  but  instead  the  mucosa  herniates  or  protrudes  through  the  muscle  layers  (Fig.  30-1).
