Measurement of:
                           Total Mucosal Thickness  (TT) 
                           Basal Zone Thickness  (BZT)
                           Papillary Height  (PH)

             
                                         TT is in arbitrary micrometer units 
                                   (in this case, BZT = 12%  and  PH = 41%)

The following studies reveal the pathology findings in patients with GERD.  They confirm that Esophageal pinch biopsies are adequate and useful in diagnosing chronic GER.  It is important to perform biopsy in order to confirm diagnosis in the absence of Reflux Laryngitis and Erosive Esophagitis.

• Morphometric Studies on Esophageal Pinch Biopsies for Reflux Esophagitis
• Clinical Endoscopic and Pathologic Manifestations of Bile Reflux Esophagitis
