Ischemic proctitis in a diabetic patient

Ischemic colitis is the most common form of intestinal ischemia, which results from lack of blood flow in the absence of mechanical obstruction. Acute ischemic coli- tis usually occurs in the descending and sigmoid colon. The rectum is affected very rarely because of its abun- dant collateral blood supply. Ischemic proctitis is usually related to a derangement in the central circulation from congestive heart failure, arrhythmia, hypotension or va- soconstrictive drugs (1). In this report we present a case of ischemic proctitis in a patient with non-insulin-depen- dent diabetes mellitus (NIDDM).
