Virtual chromoendoscopy score 'predicts UC outcomes'

The PICaSSO tool enables endoscopic scoring to more closely match histology, researchers say

A scoring tool for use in virtual chromoendoscopy can accurately detect remission and predict which patients with ulcerative colitis (UC) will have better outcomes, researchers say.


In an international multicentre study, the Paddington International virtual ChromoendoScopy ScOre (PICaSSO) was pitted against two other scoring systems to assess inflammatory activity using high definition and virtual chromoendoscopy of the rectum and sigmoid colon.

The final analysis included 302 patients with UC (mean age 48, 59% men, mean disease duration
