Clinicopathological Analysis of Obstructive Colitis Secondary to Colorectal Carcinoma

-Retrospective Investigation into Exciting Cause and Natural Course-

Abstract

Seventeen cases of obstructive colitis secondary to colorectal carcinoma were retrospectively analyzed to investigate the exciting cause and natural course.
The resected specimens were classified into three groups according to macroscopic appearance, spreading type, irregular type, and longitudinal type. The length of the ulcer and the pathological finding of each type showed healing and cicatrization occur in this order.Clinical onset of obstructive colitis was identified in seven cases, and the interval between clinical onset and operation of each type was 2.0, 16.6, and 37.5 days, respectively. Four of the seven cases underwent bowel treatment (enema, cathartic, or their combination) just before the clinical onset, and bowel treatment was thought to be the exciting cause of obstructive colitis.
