Bowel segments potentially examined:
(1) rectum
(2) sigmoid and left colon
(3) transverse colon
(4) right colon
(5) ileum
Parameters scored:
(1) deep ulceration
(2) superficial ulceration
(3) disease involvement in centimeters
(4) ulcerated surface in centimeters
(5) ulcerated stenosis
(6) non-ulcerated stenosis
score for deep ulceration =
= (12 * (number of segments showing deep ulceration)) / (number of segments examined)
score for superficial ulceration =
= (6 * (number of segments showing superficial ulceration)) / (number of segments examined)
score for disease involvement =
= SUM(surface length of disease involvement in centimeters for each segment) / (number of segments examined)
score for ulcerated surface =
= SUM(surface length of ulceration in centimeters for each segment) / (number of segments examined)
