Endoscopic Diagnosis Of Histology Type Of Colon Polyp By Using Aceto Acid Chromoendoscopy

Aim and background to improve of optical diagnosis of colon polyp histology during colonoscopy.

Methods During colonoscopy, 1.5 %-acetic acid, 5ml, was sprayed onto the identified polyps. Polyps and surrounding mucosa were observed endoscopically for 2 minutes. Then polyps were removed and sent for pathology

Use of acetic acid leads to fast acetowhitening reaction of polyps and surrounding mucosa. 2 groups were distinguished:

1. Loss of acetowhitening (LAW) of polyps occurs earlier than LAW of surrounding mucosa

2. LAW of polyps occurs later than LAW of surrounding mucosa

Conclusion acetic acid chromoendoscopy is an effective clarifying method for diagnosis of histological type.
