AB  - PhysiologyThe  basic  function  of  the  esophagus  is  to  propagate  a  bolus  from  the  oropharynx  to  the  stomach.The  coordination  of  esophageal  muscle  contractions,  vagal  innervation,  and  sphincter  relaxation  allows  this  event  to  occur.Function  testsPrimary  esophageal  motility  disorders  can  be  diagnosed  using  conventional-  or  high-resolution  manometry.Various  systems  are  available  for  reflux  testing  including  24-hour  catheter-based  pH  monitoring,  wireless  capsule  pH  testing,  and  combined  pH  impedance.Endoscopic  techniquesHigh-resolution  endoscopy,  chromoendoscopy,  narrow  band  imaging,  and  confocal  endomicroscopy  are  techniques  that  enhance  the  esophageal  mucosa,  improving  diagnostic  yield  in  Barrett’s  esophagus  (BE)  and  early  esophageal  cancer.Endoscopic  ultrasound  adds  imaging  from  adjacent  structures,  and  is  useful  for  staging  and  fine-needle  aspiration.Multiple  ablative  techniques  are  now  available  for  BE  and  early  esophageal  cancer,  and  include  endoscopic  mucosal  resection,  photodynamic  therapy,  radiofrequency  ablation,  cryotherapy,  and  endoscopic  mucosal  dissection.
