The Vienna classification of gastrointestinal epithelial neoplasia
The differences between Western and Japanese pathologists in the diagnostic classification of gastrointestinal epithelial neoplastic lesions can be resolved largely by adopting the proposed terminology, which is based on cytological and architectural severity and invasion status.
Severity of inflammation is a risk factor for colorectal neoplasia in ulcerative colitis.
In long-standing extensive ulcerative colitis, the severity of colonic inflammation is an important determinant of the risk of colorectal neoplasia and endoscopic and histological grading of inflammation could allow better risk stratification for surveillance programs.
Thirty-year analysis of a colonoscopic surveillance program for neoplasia in ulcerative colitis.
Although two thirds of patients with potentially life-threatening neoplasia benefited from surveillance, the program was not wholly effective in cancer prevention, suggesting there is no need to intensify surveillance over time.

It is appropriate to review the existing classifications and to produce a system that, in the light of new knowledge, will find widespread acceptance, was the remit given to a small multidisciplinary Working Party by the Scientific Committee of the 9th World Congresses in Gastroenterology.
Pancolonic indigo carmine dye spraying for the detection of dysplasia in ulcerative colitis
Routine pancolonic indigo carmine dye spraying would improve the macroscopic detection of dysplasia and reduce the dependence on non-targeted biopsies and careful mucosal examination aided by Pancolonic chromoendoscopy and targeted biopsy of suspicious lesions may be a more effective surveillance methodology.
Mitochondrial damage: a possible mechanism of the “topical” phase of NSAID induced injury to the rat intestine
In vivo studies with nabumetone and aspirin suggested that uncoupling or inhibition of electron transport underlies the “topical” phase of NSAID induced damage.
Factors affecting the outcome of endoscopic surveillance for cancer in ulcerative colitis.
Overlap in the spectrum of non-specific inflammatory bowel disease--'colitis indeterminate'.

Case of colitis indeterminate form a small distinctive group in the spectrum of inflammatory bowel disease which is characterised by a common pattern of pathology that presents a diagnostic dilemma.

Cancer surveillance in longstanding ulcerative colitis: endoscopic appearances help predict cancer risk
Macroscopic colonoscopic features help predict neoplasia risk in UC and it should be possible to reduce surveillance frequency to five years in this cohort.
