title: The endoscopic spectrum of segmental colitis associated with diverticulosis.
abstract: OBJECTIVE
  An endoscopic classification of 'Segmental colitis associated with diverticulosis' (SCAD) is lacking. Our aim was therefore to assess the endoscopic spectrum of SCAD, comparing it with the histological and clinical features.
  
  
  METHODS
  A prospective study was performed from January 2004 to October 2007. Diagnosis of SCAD was made on the basis of specific endoscopic and histological patterns.
  
  
  RESULTS
  A total of 6230 consecutive colonoscopies were performed during the study period. SCAD was diagnosed in 92 (1.48%) patients, with four endoscopic patterns: pattern A, 'crescentic fold disease' (52.20%); pattern B, 'Mild-to moderate ulcerative colitis-like' pattern (30.40%); pattern C, 'Crohn's disease colitis-like' pattern (10.90%); pattern D, 'Severe ulcerative colitis-like' pattern (6.50%). Most patients with patterns A (58.33%, P < 0.018) and B (89.29%, P < 0.00001) showed histological alterations resembling moderate ulcerative colitis (UC). In pattern C, larger histological variability was found (P < 0.01). All patients showing pattern D showed the typical histological alteration changes of severe UC (P < 0.0001). In pattern A (60.42%, P = n.s.) and pattern B (46.43%, P = n.s.), diarrhoea was the most common symptom whilst abdominal pain was the most frequent in pattern C (50%, P = n.s.) and pattern D (83.33%, P = n.s.) patients.
  
  
  CONCLUSIONS
  Endoscopic patterns of SCAD may range from mild to severe inflammation. The histopathological findings but not clinical features showed a statistically significant association with the degree of endoscopic severity.
