AB  - Esophageal  diverticula  are  rare  entities.  They  are  commonly  categorized  by  anatomic  location  and  etiology.  Epiphrenic  diverticula  occur  in  the  distal  third  of  the  esophagus  and  develop  by  increased  intraesophageal  pressure  secondary  to  a  motility  disorder.  They  are  considered  pulsion  diverticula.  Midesophageal  diverticula  have  traditionally  been  considered  traction  diverticula  and  are  associated  with  mediastinal  inflammation.  Recent  work  would  suggest  that  most  midesophageal  diverticula  are  in  fact  pulsion  diverticula  and  are  associated  with  motility  disorders.  Patients  with  minimal  symptoms  or  small  diverticula  should  not  be  repaired  because  of  postoperative  anastomotic  leak  rates  ranging  from  6%  to  18%  and  a  perioperative  morbidity  rate  of  33%  to  45%.  Diverticulectomy  and  myotomy  can  be  recommended  in  patients  who  are  symptomatic.  The  repair  of  large  asymptomatic  diverticula  may  warrant  repair  as  well.  Symptoms  typically  include  dysphagia,  regurgitation,  or  weight  loss.  Less  often,  chest  pain,  heartburn,  aspiration  pneumonia,  or  vomiting  have  been  noted.  It  is  sometimes  difficult  to  determine  the  contribution  of  a  diverticula  versus  a  primary  motility  disorder  as  the  cause  of  a  patient’s  symptoms.
